Description

Title: SUCTION ADAPTER FOR SYRINGE
Technical Field
The present invention relates to a suction adapter for a syringe engaged in a needle and a needle hub of a syringe, and in particular to a suction adaptor for a syringe which makes it possible to reliably inject an injection liquid at a desired depth in a skin by raising a corresponding skin portion in a needle direction with the help of a negative pressure when injecting a curved portion of a skin.
Background Art
Generally, a syringe is equipped with a cylinder having a nozzle, a piston engaged in the cylinder, and a packing engaged to a front end of the piston. An injection liquid is stored in the cylinder, and the stored injection liquid is discharged to the outside of the syringe through the nozzle by means of the piston which pushes the stored injection liquid in a nozzle direction. A syringe needle formed of a needle and a needle hub is engaged in the nozzle of the syringe for injecting an injection liquid into a human body. The method for directly injecting an injection liquid into a human body by using a syringe is widely used for curing a patient, and the above method is even used in a beauty and a plastic surgery field in recent years. A new injection operation method, which uses an injection stuff such as filler and toxin, is widely used. When the above syringe is actually used, the position and depth for injecting an injection liquid might be different depending on a state of a patient, and a kind of an injection liquid. In the injection operation method in a beauty and plastic surgery field, a certain injection liquid is injected into a dermis and a fat layer of a skin by using a syringe. The effects of an injection decrease unless an injection liquid is injected into a precise portion of a skin, so a tense concentration and a professional skill are needed. In a process that an injection liquid is injected by pressing a piston, a skin layer of a corresponding portion is pressurized, so a skin layer of a corresponding portion becomes thinner than its surrounding portion, which makes it hard to precisely inject at a desired depth. In order to overcome the above problems, a skin portion to be injected is raised by fingers, and then a needle is injected. Since the above processes are repeatedly performed a few times, it causes a lot of inconveniences. When an injection operation is performed using a multi-needle consisting of multiple needles, since an area to be injected is wide, it is very hard to directly raise a skin to be injected. Since the portions to be injected are generally curved, not flat, it is very hard to inject at a uniform depth in a skin.
Disclosure of Invention
Accordingly, it is an object of the present invention to provide a suction adaptor for a syringe which overcomes the problems encountered in the conventional art.
It is another object of the present invention to provide a suction adaptor for a syringe which makes it possible to inject a uniform depth in a skin to be injected by raising a skin of a patient in a direction of an injection apparatus by using an air suction unit while overcoming the problems found in a conventional art in which a skin to be injected is raised by fingers.
To achieve the above objects, there is provided a suction adaptor for a syringe which is engaged to a syringe needle formed of a needle and a needle hub and is connected with an air suction unit for supplying a negative pressure to a skin which will be injected, which comprises a first space part which is formed in a lower side of the suction adaptor for accommodating a needle hub; a second space part which is formed in an upper side of the same with its upper side being open; a through hole which connects the first space part and the second space part, so a needle engaged to the needle hub passes through the through hole and is protruded from the upper side of the second space part; and an air suction unit connection part which communicates with the second space part and is connected with the air suction unit.
Here, the first space part has a shape corresponding to the needle hub.
The protrusion part is formed in the second space part while corresponding to the needle protruded through the through hole.
At least one through hole is formed depending on the positions and the number of the needles concurrently engaged to the needle hub. The protrusion part has the same height as an outer upper end of the second space part so that the injection liquid is not leaked into the second space part by means of the negative pressure of the air suction unit.
A close contact member is formed on an outer upper surface of the second space part for preventing an external air from being inputted into the second space part.

Figure 6A is a perspective view illustrating a suction adaptor for a syringe according to further another embodiment of the present invention. Figure 6B is a cross sectional view illustrating a suction adaptor for a syringe of Figure 6A.
As shown in Figure 1 , the suction adaptor 1 for a syringe is engaged to a syringe needle 9 consisting of a needle 8 and a needle hub 7 and is connected with an air suction unit for thereby providing a negative pressure to a skin portion to be injected.
The suction adaptor 1 for a syringe includes a first space part 10 for accommodating a needle hub, and a second space part 30 which is provided on an upper side of the first space part and has an air suction connection part 50 communicating with the air suction unit. The first and second space parts 10 and 30 communicate with each other by means of a through hole, and the through hole 23 is formed in a shape of a hole through which the needle passes while corresponding to the needle. A protrusion part 60 might be further provided, so that the through hole 23 is extended for thereby surrounding the needle 8 protruded into the second space part through the through hole 23. A needle 8 passes through the through hole 23 of the protrusion part 60. A close contact member 70 might be further provided on an upper surface of the second space part while closely contacting with the same. The close contact member 70 might be further provided in the protrusion part 60 as well.
The suction adaptor for a syringe according to the present invention will be described with reference to Figure 2. As shown in Figure 2, the suction adaptor 1 for a syringe according to the present invention comprises a first space part 10 which is formed in a lower side of the suction adaptor 1 for accommodating the needle hub 7, a second space part 30 which is formed in an upper side of the same with its upper side being open, a through hole 23 which connects the first space part 10 and the second space part 30, so a needle engaged to the needle hub 7 passes through the through hole 23 and is protruded from the upper side of the second space part 30 and an air suction unit connection part 50 which communicates with the second space part 30 and is connected with an air suction unit(not shown). The first space part 10 is formed in a lower side of the suction adaptor 1 for a syringe and is formed for accommodating the needle hub 7 in a shape corresponding to the needle hub with its lower side being open. A partition wall 20 is formed in an upper side of the first space part 10 for separating the first space part 10 from the second space part 30. The through hole 23 is formed in the partition wall 20 at a portion corresponding to the position of the needle 8 engaged to the needle hub so that the needle 8 engaged to the needle hub 7 is extended into the second space part 30 through the partition wall 20 in case that the needle hub 7 is engaged to the first space part 10. The second space part 30 formed in an upper side of the first space part 10 communicates with the first space part 10 through the through hole 23, and the air suction unit connection part 50 is connected with the air suction unit(not shown) forming in a negative pressure in the second space part 30 by sucking the air from the second space part 30. The air suction unit connection part 50 is formed in a cylinder shape having a hollow part communicating with the second space part 30 and is connected with the air suction unit through a connection pipe(not shown).
The first space part 10 will be described in detail. The first space part 10 is formed in a shape corresponding to the needle hub 7, so that the needle hub 7 is inserted into the first space part 10. So, the first space part 10 might be formed in various shapes depending on the shape of the needle hub 7. Since a cylindrical needle hub engaged with the needle is used in the embodiment of Figure 2, the first space part is formed in a cylindrical shape. However, in case of the suction adaptor for a syringe shown in Figures 5A through 6B, the first space part 10 is formed in a shape corresponding to the shape of the multiple- needle hub formed of a plurality of needles with its upper surface being formed in a rectangular shape or a square shape.
The through hole 23 is formed depending on the number and positions of the needles 8 engaged to the needle hub 7 installed in the first space part 10. Figure 3 is a view illustrating a state that the needle is engaged to the suction adaptor 1 for a syringe. The needle hub 7 includes an inlet 7a connected with a nozzle 4, and an outlet 7b communicating with the needle 8. The inlet 7a of the needle hub 7 is connected with the nozzle 4 of the syringe cylinder, and the injection liquid L inputted from the nozzle 4 of the cylinder is inputted into the outlet 7b of the needle hub. At this time, the needle 8 is engaged to the outlet of the needle hub.
The protrusion part 60 is formed in the second space part 30 while corresponding to the needle 8 protruded through the through hole 23 so that the injection liquid L is not leaked from the needle 8 by means of a negative pressure formed by the air suction unit. Since the through hole 23 is extended in the interior of the protrusion part 60, the needle 8 is positioned in the through hole 23 of the protrusion part 60. So, the protrusion part 60 surrounds the needle 8.
Since the protrusion part 60 is formed depending on the number of the needles 8 engaged to the needle hub 7, one protrusion part 60 is formed in the second space part 30. However, as shown in Figures 5A through 6B, in case that the needle is a multi-needle formed of a plurality of needles, a plurality of protrusion parts are formed as corresponding to a plurality of needles.
It is preferred that the upper surface of the protrusion part 60 corresponds to the height of the upper surface of the second space part 30.
When an upper surface of the second space part 30 closely contacts with a skin, since the upper surface of the protrusion part 60 contacts with the skin, the needle 8 installed in the protrusion part 60 is not affected by means of the negative pressure generated by the air suction unit, so it is possible to prevent a unnecessary leakage of the injection liquid.
Figure 4 is a schematic view illustrating a state that an injection liquid is injected into a skin by using a suction adaptor 1 for a syringe according to the present invention. When an upper surface of the suction adaptor 1 for a syringe is closely contacted with a skin of a patient, and a negative pressure is applied to the second space part 30 by driving an air suction unit. The skin of a patient to be injected is raised in an injection apparatus direction by means of a pressure difference occurring by means of the negative pressure. The piston 5 and cylinder 3 of the syringe are pressurized toward the raised skin in a direction of a skin of a patient for thereby injecting an injection liquid L. At this time, the length of the needle 8 protruded in the direction of the upper surface of the protrusion part 60 is different depending on the kind of the injection liquid and the thickness of the skin. In case that a beauty injection stuff such as filler or toxin is injected, it is preferred that an end of the needle 8 reaches a boundary potion of the dermis D and the fat layer F through an epidermis E. In order to form an exposure portion of the needle 8 in order to correspond to the depth of the insertion, it is possible to adjust the heights of the protrusion part 60 and the second space part. For example, it is possible to determine the heights of the upper surface of the second space part and the end of the protrusion part of the suction adaptor 1 for a syringe to the height lower by 3mm with respect to the weight of the end of the needle so that the length of the needle exposed to the outside of the protrusion part 60 becomes 3mm.
In addition, a close contact member 70 may be further provided on an upper surface of the suction adaptor 1 , namely, on an upper surface of the second space part 30. A ring shaped close contact member 70 made of silicon, rubber or something and corresponding to an upper surface of the second space part 30 is provided so as to prevent air from being externally inputted into the second space part 30 when a close contact reliability is poor due to the curved surfaces in case that the air is sucked by closely contacting the suction adaptor. Figures 5A through 6B are a perspective view and a cross sectional view illustrating a suction adaptor for a syringe according to another embodiment of the present invention. When the shape of the needle hub 7 changes depending on the number of the needles 8, it is possible to change the shapes of the first and second space parts 10 and 30 of the suction adaptor 1 for a syringe while corresponding to the changed shapes of the needle hub 7. Namely, in a multi- needle formed of a plurality of needles, a suction adaptor for a syringe according to the present invention might be engaged to the above needle hub. In case that multiple needles are used, since the area of the injection performed one time is wide, it is hard to raise the skin of a corresponding portion with fingers. In this case, the suction adaptor for a syringe according to the present invention can be usefully used.
Figure 5A is a view illustrating a suction adaptor for a multi-needle formed in a 3x2 arrangement. Namely, Figure 5A shows a suction adaptor 1 for a syringe which is engaged in a multi-needle in which three needles are arranged in a horizontal direction, and two needles are arranged in a vertical direction. A plurality of through holes 23 are formed in the portions corresponding to the needles above the upper side of the first space part 10 in which the needle hub is engaged. The upper side of the second space part 20 and the end of the protrusion part 60 are extended while corresponding to the length of the exposed needle. It is needed to expose the needle as much as a corresponding depth so that the needle is inserted at the depth of the skin layer into which an injection liquid L is inputted. The heights of the second space part and the protrusion part are determined while corresponding to the length of the needle except for the exposed part of the needle for an exposed length adjustment of the needle. Figures 6A and 6B are views of a suction adaptor for a multi-needle formed in a 6x6 arrangement. The multi-needle of Figure 6B is further equipped with an exposure length adjuster 7C of the needle. The adjuster positioned in a front end of the needle hub might be connected with the first space part. The needle having the adjuster is externally exposed to the outside through the protrusion port.
As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
Effects
In the present invention, a suction adaptor is closely attached to an injection portion by means of a suction adaptor for a syringe, and the air in a second space part is sucked by means of an air suction unit, so a skin layer is sucked and raised up in a direction of an injection apparatus for thereby injecting an injection liquid at a desire depth of a skin.
