The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

Referring to the accompanying drawings, the adhesive multi-function negative pressure drainage device of the present invention comprises an isolation cover body for being buckled on a wound, a wound anti-inflammatory liquid supply branch pipe A and a waste which can be inserted into the wound cavity through the isolation cover body. a liquid suction branch pipe B, characterized in that: the isolation cover body is made of a flexible material that can adapt to the surface of the curved wound skin, and has an upper layer 6, an adhesive layer 2 having a port 10 in contact with the surface of the human skin, and An underlying layer 3 connected in a ring-like shape between the outer edge of the upper layer and the periphery of the mouth of the bonding layer, the wound anti-inflammatory liquid supply branch pipe A and the waste liquid suction branch pipe B passing through a closed window 9 on the isolation cover body Extend into it.

In order to facilitate the manufacture, the wound anti-inflammatory liquid supply branch pipe A and the waste liquid suction branch pipe B extend into the isolation cover body through the intersection of the upper layer and the ring-like lower layer.

For the convenience of operation, an operation port 7 is formed on the upper layer of the isolation cover body, and the upper layer of the isolation cover body is made of a transparent material. After adjusting the position of the B branch pipe in use, the disposable sealing film is pasted on the operation port. If adjustment is needed again, the disposable sealing film can be torn off or cut open, adjusted again through the operation port, and closed again with a disposable sealing film.

In order to ensure the sealing property of the isolation cover body, the wound anti-inflammatory liquid supply branch pipe A and the waste liquid suction branch pipe B are put together on the positioning blockage 5 and protrude into the isolation cover body, and the positioning block 5 and the corresponding closed window on the isolation cover body are arranged. 9 sealed fit.

In order to help balance the air pressure and avoid negative pressure injury caused by excessive negative pressure, the positioning blockage 5 is also provided with a vent pipe C, and the inner end of the vent pipe C extends into the isolation cover body.

In order to facilitate the actual operation, it is convenient for each tube to control the length that actually needs to be extended, the wound The anti-inflammatory liquid supply branch pipe A, the waste liquid suction branch pipe B and the vent pipe C are arranged side by side to form a combined pipe member 14 which can be mutually peeled off.

In order to prevent the suction port from being blocked by the foreign matter in the front port of the branch pipe B, the liquid suction side pipe 15 is disposed on the side wall of the waste liquid suction pipe B which is inserted into the isolation cover body, and the outer end is connected with the atmosphere bypass control valve 8. When the negative pressure in the drain is too large and a negative pressure injury may occur on the wound, the atmospheric bypass control valve 8 disposed on the outer end of the waste suction branch B can be immediately opened, and the internal and external pressures of the drain can be quickly balanced. , reduce the pain of patients. Open the gas bypass control valve to temporarily reduce the suction negative pressure, and also make small adjustments to the pipe introduced into the cavity to ensure smooth flow. The sealing member 4 is a disposable sealing film adhered to the operation port, so that the drainage device and the wound cavity form a closed space to block air.

In order to facilitate the wound cleaning process, the isolation cover body is provided with a plurality of closed windows, and a blockage 16 matched with the closed window. In actual operation, several sets of combined pipe fittings are accessed as needed, and for unnecessary, the blockage is used. Blocked.

In practice, the port 10 of the glue layer can be trimmed as needed.

In order to facilitate the confirmation of the length and position of the branch pipe under fluoroscopy, a non-X-ray transmission mark line is provided on the combined pipe member.

When working, the medical staff first trims the size of the mouth according to the shape of the wound and then attaches the isolation cover body, and introduces the combined pipe fittings with the wound anti-inflammatory liquid supply branch pipe A, the waste liquid suction branch pipe B and the vent pipe C, and can be taken as needed. Use several sets of combined pipe fittings to extend into the closed window, and close the window with the positioning plug. [The remaining unused closed window can be blocked by plugging. Then, through the operation port, the wound can be used to inhale the branch pipe. 8. The waste liquid sucks out the branch pipe B. And the vent pipe C for the adjustment of the placement and extension length (since the placement positions of the A, B, C pipes in the actual operation are not fixed, the combined pipe pieces can be peeled off each other, which is very convenient in practical operation, only need to Tube peeling, cutting according to length; and if the three tubes cannot be peeled off, When cutting, it is inevitable to meet the different requirements of different positions of the three pipes), and then seal the disposable sealing film; the external end of the waste liquid suction pipe B is connected to the adjustable continuous negative pressure source and through the atmosphere bypass control valve, the inner end is directly placed In the isolation cover body or the shallow part of the wound cavity, the external end of the wound anti-inflammatory liquid supply branch pipe A is connected with the anti-inflammatory rinse liquid, the inner end is placed deep into the wound cavity, the outer end of the vent pipe C is connected with the cleaned air after filtering, and the inner end and the cavity of the isolation cover body The rooms are connected to each other to balance the air pressure.

The anti-inflammatory liquid enters the wound cavity from the anti-inflammatory liquid supply branch pipe A, rinses the wound, and then the waste liquid is discharged from the waste liquid to the branch pipe B. When the isolation cover body is bonded to the surface of the human skin through the adhesive layer, the isolation cover body 1 and the wound The cavity 12 constitutes a closed space, which is isolated from the outside air, so that a full vacuum suction space is formed, and a closed vacuum suction treatment is implemented. When the negative pressure is introduced, the double mechanism of the adsorption and the negative pressure adsorption makes the deflector fixed very firmly. Under the negative pressure, the flexible isolation cover can be completely closed, so that the suction tube and the drainage liquid form the most direct contact, which is beneficial to timely Thorough drainage (but if it is made of hard material, it does not match the curved skin, and the sealing is poor, which makes the drainage effect poor). When the drainage fluid has a paroxysmal increase (such as the paroxysmal gushing of the intestinal fluid), the flexible isolation cover can simultaneously have the function of temporarily storing the bag, and the drainage liquid is temporarily retained in the isolation cover body. Then, the waste liquid is sucked out of the branch pipe B to be discharged. At the same time, it can prevent dust and bacteria in the air from invading the inside of the wound cavity, control the flow of waste liquid everywhere, and effectively protect the normal skin tissue around the wound surface. The upper layer is made of a transparent material, which is favorable for observation, has good conformality of body surface, can adapt to various conditions such as flat, concave and convex surface of the human body, and the outer edge of the outer layer of the adhesive layer is isolated for convenience. The shape of the cover conforms to the surface of the human skin, thereby facilitating the reduction of stress and enhancing the sealing of the fit.

The invention has the characteristics of safety and hygiene, simple operation and remarkable curative effect, and obviously shortens the treatment period, greatly reduces the suffering of the patient, saves the medical expenses of the patient, reduces the workload of the medical staff, and has great promotion and application value.
