Description

The invention claims to be submitted to the Chinese Patent Office on December 7, 2011, the application number is 201110404616.1, and the invention name is "body skin skin fixation and surface skin movement wrinkle restriction device" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for attaching an article to a skin of a body surface, and more particularly to a medical device device for medical catheters, dressings, insulin pump needles, electrode sheets and devices for fixation on the skin of the body surface and skin wrinkles for wound surface.

Background technique

In many cases, people need to attach or fix items on the surface of the body for a short time or a long time, especially in medical health care and wearing decoration processes, such as wound dressings, central venous catheters, intravenous indwelling needle catheters, drainage tubes, Body electrode guide piece, dialysis tube, intravenous infusion needle, insulin pump infusion needle, gastrointestinal nutrition tube, electrode sheet, sensor, vibrating massager or piece, foot pad, boutonniere, bra, breast pad, earring, earring , pendants, underwear, etc. At present, in the medical health care, the above-mentioned health care products are usually fixed to the skin surface by using various single fixed adhesive layers, and the adhesive layer (adhesive) includes a tape with a medical adhesive, a non-woven fabric, A transparent film, a hydrocolloid film, a medical foam or a medical adhesive applied to the surface of the medical device to be fixed is directly adhered to the skin surface. For example, when fixing medical catheters and protective catheters for infusion of wound medical catheters and injection wounds, the most common and most effective method in clinical practice is to use a transparent film (PU film) to fix the adhesive layer (post). The advantages are softness, ultra-thinness, certain elastic retraction force, excellent compliance, tight fit, and the same displacement and wrinkles as the skin moves and wrinkles. The fixed layer can better adhere to the surface of the skin, and it also produces the same displacement and wrinkles as the skin. Therefore, it adheres to the surface of the skin and is firm and firm, and is not easily peeled off, and is transparent and visible, and the wound condition can be observed at any time. However, it has the following drawbacks: First, the fixed medical supplies are easily displaced along with the skin, wrinkles, and the movement of the catheter tip in the human body, which easily damages the inner body tissue of the blood vessel, leading to endovascular inflammation. And thrombosis, it is also easy to cause dressings and wounds, the catheter injection port itself is displaced and wrinkled, especially on the surface of the skin at the joint; Second, the catheter injection wound and surrounding skin are covered by compression bonding, There is a gap between the fixed catheter and the skin transition area, which causes the tensioned membrane to pull the injection port or the surrounding skin to cause mechanical stimulation and cause an inflammatory reaction such as redness and swelling, resulting in infection of the injection port. Third, sweat can not be seen out, and the surface of the skin and the surface of the skin gather, which easily leads to infection of the wound at the injection port. The other is to use a relatively rigid, hard fixing adhesive layer for spunlace nonwovens, foams, foams, tapes, etc. with adhesives to fix medical supplies on the skin or to fix them. The core, the village mat, and the hollow protective pad are used to protect the wound on the wound and the catheter injection port. The advantage is that it absorbs sweat, can't or less wrinkles with the skin, and also displaces and wrinkles itself, thus preventing and limiting the Covering the adhered medical supplies and the skin to produce displacement, wrinkles, and wounds, displacements and wrinkles in the catheter injection port, and prevent mechanical damage to the wound and catheter injection port. However, the drawback is that when sweating occurs and the skin is strained due to displacement or wrinkles, the adhesion is poor, and the adhesive force is lowered, so that it is easily peeled off from the skin surface, and the fixed object is detached. It can be seen that the above fixed protection technology uses a fixed adhesive layer to firmly adhere the medical article to the skin surface to achieve the purpose of fixing the medical article and defining the protection of the wound, and cannot overcome and solve the above respective defects.

Different from the surface of a general object using a fixed adhesive layer with an adhesive to fix the article, the physiological characteristics of the skin on the surface of the human body will affect the fixation of the fixed adhesive layer. First, the skin is a In the organ that secretes sweat, the sweat that is secreted will reduce the viscosity of the fixed adhesive layer, or even fall off. Second, the skin is a relatively soft surface that can be moved and wrinkled by external force, especially in joints with motor function, and the older the skin, the more wrinkles the skin are, the more likely it is to wrinkle. When a rigid protective fixing adhesive layer which is difficult to wrinkle or wrinkle is adhered to the skin surface, when the adhesive surface is subjected to an external force to generate a tension of moving wrinkles, it first restricts the tension against the moving wrinkles. Displacement of the surface of the skin, wrinkles, when the adhesion is insufficient to resist this tension, the adhesive surface is peeled off, so when only a rigid fixed adhesive layer is used to bond the article to fix the skin surface, the advantage is that it It resists the tension of the skin moving wrinkles to limit the movement wrinkles of the skin surface surrounded by the adhesive surface or its opening. However, the disadvantage is that it requires resistance to the skin to resist the tension of the skin moving wrinkles, when the adhesion is insufficient to resist the tension of the skin moving wrinkles or when the surface tension with the skin is increased, the rigidity is protected. The fixed adhesive layer will separate and fall off. However, when a compliant protective fixed adhesive layer adheres to the surface of the skin, it is soft, ultra-thin, and compliant, so that it can be accompanied by wrinkles of the texture of the skin to produce the same displacement wrinkles, regardless of any displacement wrinkles. The skin can maintain a good adhesion to the skin surface, so the tension of the skin moving wrinkles is not resisted by the adhesion force, so when the adhesive layer is used to protect the medical product or the wound which fixes the skin surface, The advantage is that the adhesion is tight and firm, and it is not easy to fall off even in the presence of sweat. However, the defect is to protect the fixed medical article or the wound which is protected by the fixed adhesive layer from displacement and movement wrinkles with the movement of the skin surface, and the fixation of the catheter with the catheter injection or the fixation of the wound dressing will make the injection Catheter movement at the entrance and wrinkle displacement of the wound surface results in re-injury of the wound and wound and damage to the wound tissue due to relative displacement of the dressing. Third, allergic skin wounds are allergic to the adhesive layer and cause inflammation and infection. Therefore, it is necessary to avoid the adhesive layer directly injecting the catheter into the wound, and surgery. Wounds and traumatic wounds.

In addition, children and comatose patients are prone to accidental traction and fall off, so it is necessary to use more robust techniques and methods to fix skin surface medical supplies, especially central venous catheters that can cause serious complications. CVC, peripheral venous central venous catheter PICC, longer-term indwelling intravenous indwelling needle catheter, hemodialysis catheter, etc., require both a fixed catheter and a medical device that protects the wound from injury.

In addition, there are also some special catheter fixation devices used to fix the catheters on various skin types of the skin, mainly by attaching some gripping or mechanical devices to the anchor pads attached to the skin surface to fix the catheters, but these devices are free. Gap, external force can cause small displacement of the catheter, causing the catheter tip to damage the inner wall of the blood vessel and cause complications such as phlebitis. At the same time, the outer diameter and shape of the catheter produced by different manufacturers are different, so it is necessary to produce a special fixing device suitable for a certain manufacturer to match. This will increase the cost and inconvenience to the user. At the same time, the use of these fixing devices can only serve as a fixed catheter. The protective treatment of the catheter injecting the wound also requires the use of a transparent film or tape as in the first method described above. Padded non-woven fabrics, hydrocolloids and other dressings are applied to protect the catheter from injecting into the wound.

In addition, the above-mentioned methods and techniques used clinically to fix medical catheters and protect nursing wounds are achieved by using fully enclosed cover adhesion, so it is necessary to replace the adhesive layer to re-sterilize the catheter injection or wound. Therefore, it is necessary to frequently change the adhesive layer frequently to clean the wound and increase the medical cost.

For insulin pump infusion needles, ostomy bags, electrode pads, vibrating massagers, etc., the clinical fixation of the skin surface is mainly using a rigid plastic or silicone sheet with an adhesive layer or a layer attached to the surface. a nonwoven fabric of an adhesive layer to fix the above medical product to the skin, and these methods are In the meantime, the above-mentioned rigid fixing adhesive layer is used for fixing the medical article, and thus there is a defect in that the rigid fixing adhesive layer is used to fix the medical article.

In the wearing of clothing accessories, a single layer of adhesive layer is generally used to fix the foot pad, the boutonniere, the chest chest, and the breast pad to the surface of the skin, which also has the above defects, especially in the summer, when people wear little clothes. People need a firm and soft, sweat-proof, fixed adhesive layer to secure the wear and accessories. Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a body surface skin article fixation and surface skin movement wrinkle restriction device which both secures the article to a firm surface of the skin while at the same time limits skin movement wrinkles.

In order to solve the above problems, the present invention adopts the following technical solutions:

In order to achieve the above object, the technical solution of the present invention is:

A body surface skin article fixing and surface skin moving wrinkle limiting device comprises a main body, wherein the main body comprises a flexible fixing layer and a rigid fixing layer, and the flexible fixing layer and the rigid fixing layer are bonded to each other, and the periphery of the flexible fixing layer The boundary extends beyond the peripheral boundary of the rigid fixed layer, and the lower surface of the flexible fixed layer and the rigid fixed layer are provided with an adhesive layer, and the flexible fixed layer can move the wrinkles according to the bonded skin texture to generate the same movement The pleats, the rigid fixation layer can limit the movement wrinkles of the bonded flexible fixation layer on the skin.

The technical solution can comprehensively utilize the respective health care products or general products of the skin surface by adhering to the skin surface by using the incomplete overlapping adhesion of the fixing layers of two different material properties and adhesive properties to each other. The advantages and characteristics (ie, firmness and stability) of the fixation of the skin parts on the body surface, the characteristics of the flexible fixation layer are ultra-thin, and can be attached to the surface of the skin. The same wrinkles occur when the surface texture of the skin is wrinkled, and the same wrinkles are generated. A transparent film (PU film) can be preferably used. The rigid fixing layer is characterized in that it is harder and thicker than the flexible fixing layer, and can not be accompanied by the moving wrinkles of the surface skin texture after bonding to the skin surface, and the same moving wrinkles can be generated, and no wrinkles can be generated, which can be fixed according to the fixing. The material needs to be selected from materials. These materials can be soft materials that satisfy the comfort of the skin. They can also be hard, inelastic, and non-deformable materials, including plastics, silicones, foams, foams, hydrocolloids, and nonwovens. Or, that is, a material that can cause the same movement wrinkles without being accompanied by the moving wrinkles of the surface skin texture after bonding to the skin can be used as the rigid fixing layer. Therefore, when the skin adhered by the flexible fixing layer moves and wrinkles under the action of an external force, almost no tension is generated between the flexible fixing layer and the adhesive surface of the skin, so that no matter how the skin is displaced or wrinkled, the flexible protection is fixed. The layers will not separate from the surface of the skin. When the rigid fixing layer is adhered to the skin surface, the rigid fixing layer resists the tension generated by the skin wrinkle deformation, and limits the skin wrinkles. When the force of the skin wrinkle displacement is greater than the adhesive force of the rigid fixing layer on the skin, The rigid fixation layer will fall off, especially when the skin is sweating and immersed. However, when the rigid fixing layer is bonded to the surface of the flexible fixing layer which has been adhered to the surface of the skin, the adhesion is greatly enhanced, which is sufficient to resist the tension generated by the flexible fixing layer and the moving wrinkles of the skin on the adhesive surface, and the rigidity is fixed. The layer does not separate from the surface of the flexible fixing layer, nor does it affect the firm bonding of the flexible fixing layer and the skin surface, while the rigid protective fixing layer can limit the movement wrinkles of the bonded flexible protective fixing layer and the fixed The movement of medical supplies and the skin surface of the wound surrounded by the opening move wrinkles, thus avoiding the skin surface wrinkles on the wound surface and damaging the wound, limiting the increase of wound tension, preventing tearing and cracking of the wound, and avoiding the infusion catheter Displacement damages the infusion catheter wound. Moreover, since the flexible fixing layer and the rigid fixing layer are bonded to each other, the peripheral boundary of the flexible fixing layer exceeds the peripheral boundary of the rigid fixing layer, so the peripheral edge bonded to the skin The boundary is a flexible fixed layer, so the same moving wrinkles can occur along with the moving wrinkles of the surface skin texture, and the same wrinkles are generated without separating and peeling off, so the flexible protective fixing layer and the rigid protective fixing layer are matched with each other. Bonding to fix body parts (such as wound dressings, medical catheters, Yueliang ornaments, etc.) is very strong and not easy to separate from the skin, and is quite stable without moving.

Preferably, the flexible fixing layer and/or the rigid fixing layer are provided with openings that open the upper and lower end faces thereof. This design allows the fixture to be in direct contact with the skin surface through the opening to achieve its function, such as an electrode pad, massager. At the same time, the adhesive layer is prevented from directly bonding the wound. The opening of the rigid fixing layer can surround the wound and the catheter around the wound to surround the wound and limit the increase of wound tension and the movement wrinkles of the skin on the wound surface, preventing the wound from tearing and splitting. To avoid wound damage caused by wound skin wrinkles, wounds and dressings and relative displacement friction of the infusion catheter, and the dressing covered by adjusting the thickness of the rigid fixing layer with the opening and the volume of the opening thereof can be permeablely Contact with secretions to absorb wound exudate, preventing foreign body contact allergic reactions caused by dressing compression contact with wounds and direct adhesive catheter infusion wounds, and wound re-injury caused by dressing and wound secretion adhesion.

Preferably, the outer edge of the flexible fixing layer and/or the rigid fixing layer communicates with the opening through a slit. This arrangement is such that when the catheter is infused with wound protection and catheter fixation, the opening surrounding the catheter is injected into the wound through the gap provided as a base layer.

Preferably, the rigid fixing layer is bonded to a substantially intermediate portion of the flexible fixing layer.

Preferably, the flexible fixing layer serves as a substrate fixing layer, and the adhesive layer provided on the lower surface is used for bonding with the skin and the object to be fixed. This arrangement enables the rigid fixing layer to be firmly fixed to the surface of the flexible fixing layer, so that the rigid fixing layer exerts its limit to the flexible fixing layer to which the bonding is adhered and the accompanying skin wrinkles, preventing the prior art from using only the flexible fixing layer. Made when fixing skin surface items The movement of the fixed article on the skin and the negative effects of such movement, such as central venous catheter displacement, movement wrinkles of the skin wound, and relative displacement friction of the skin wound and the covered dressing, can damage the wound and catheter infusion wound It is not affected by sweating and immersion, and will not separate and fall off under the action of external force and joint activity.

Preferably, the rigid fixing layer serves as a base fixing layer, and the lower surface is bonded only to the skin or to the skin and the object to be fixed. In this arrangement, when the lower surface of the rigid fixing layer is only bonded to the skin, the rigid fixing layer can be used as a supporting pad for the fixed object, so as to prevent the skin from being directly pressed and pressed. In addition, this arrangement allows the flexible fixing layer to completely cover and adhere to the rigid fixing layer to enhance the waterproof function.

Preferably, the upper surface of the rigid fixing layer is provided with an adhesive layer composed of a discontinuous adhesive region. This arrangement allows the fixed object to be adhered to the upper surface and supports the fixed object to make it fixed more firmly and to prevent the fixed object from directly pressing the skin, and also to cover the flexible fixing layer on which the cover is fixed to fix the fixed object. Or other fixed layers are easily torn off.

Preferably, a notch is provided at the edge of the flexible fixing layer and/or the rigid fixing layer. This arrangement makes it easier and more convenient to fix the catheter and the like.

Preferably, a dressing is further disposed between the flexible fixing layer and the rigid fixing layer to prevent the adhesive layer from directly bonding the catheter into the wound or the general wound to prevent damage to the wound.

Preferably, a pad body is further disposed under the main body or a flexible fixing layer or a rigid fixing layer, and the pad body has a through hole for guiding the upper and lower sides of the pad body. If the pad has the same characteristics as the rigid fixing layer, it will be equivalent to the rigid fixing layer.

Preferably, the rigid fixation layer comprises an article to be secured. Some of the objects to be fixed to the skin itself have the material properties of the rigid fixing layer, and thus are fixed by the surface adhesive or the rigid chassis containing the adhesive layer bonded to the surface of the flexible fixing layer as the substrate fixing layer, were able Avoid separating and peeling off due to skin tension and sweating when directly attached to the skin surface. These fixtures include any rigid article that needs to be secured to the surface of the skin.

Compared with the prior art, the present invention has the following advantages:

The flexible fixing layer and the rigid fixing layer are disposed, and the boundary of the flexible fixing layer exceeds the boundary of the rigid fixing layer. Since the flexible fixing layer is bonded to the skin surface or other articles, the compliance and the adhesion are good, so it is not easy to fall off from the skin surface. Even in the case of sweating and immersion, the skin surface items can be firmly and stably fixed, and at the same time, since the rigid fixing layer is provided, the skin movement wrinkles caused by the flexible fixing layer can be avoided as much as possible, and the present invention can be avoided as much as possible. In the prior art, only the flexible fixing layer (such as a transparent PU film or a PE film) is provided, and the surface of the skin adhered by the external force is displaced by the movement of the skin, and the spunlace is prevented from being spun. A rigid fixing layer with an adhesive layer such as cloth, hydrocolloid, foam or the like causes a problem that the fixed adhesive layer is detached under the action of an external force of tension stretching by the skin moving wrinkles.

Further, an opening is provided on the flexible fixing layer and/or the rigid fixing layer, so that the wound, the skin displacement and the wrinkle under the external force of the catheter injection port can be effectively protected and restricted, and the wound is damaged; and the rigid fixing layer can be avoided and / or the flexible fixation layer directly bonds, tightly compresses the inflammation and infection caused by the injection of the catheter into the wound. At the same time, it can also restrict or reduce the movement or wrinkle of the skin surface or the wound skin area surrounded by external force, and avoid the damage of the injection port caused by the movement of the catheter due to the displacement of the skin. In addition, the opening is provided to prevent infection of the catheter and the instability of the catheter due to the accumulation of sweat at the wound site.

Further, an opening is provided on the flexible fixing layer and/or the rigid fixing layer to allow direct contact with the surface of the skin by the fixture, such as an electrode sheet, a vibration massage sheet or a device.

Further, a cover body is arranged on the opening, and the catheter can be injected into the wound at any time for cleaning and elimination. There is no need to change dressings for toxic or medical treatment.

Further, the rigid fixing layer can serve as a receiving pad for the fixed object, which can effectively alleviate or even prevent the pressing effect of the fixed, relatively heavy article on the skin surface.

Further, in the technical solution, since the opening or the opening and/or the passage are provided, the wound or the catheter infusion wound which requires different treatment methods can be debrided, drained and partially through the openable opening or the passage. Treatment of drugs, physics, nutrition, growth factors, negative pressure, etc., while creating specific environments that promote healing, such as aerobic, anaerobic, dry, wet, sterile and bactericidal environments, to promote rapid wound healing.
