Description

 Paste type multifunctional negative pressure drainer

 The invention relates to a glue type multifunctional negative pressure drainer. Background technique

 At present, drainage treatment and local anti-inflammatory treatment are required for the trauma of the patient and the wound left after the surgery. Conventional methods include passive drainage and active drainage. For patients with severe inflammation, local disinfection with an anti-inflammatory solution is applied. These conventional practices have the following disadvantages: 1. The tape of the drainage material and the irrigation tube is not strong enough to be easily detached; 2. The suture and the irrigation tube are firmly positioned, but the suture and cutting of the suture have obvious damage to the skin; Only rely on gauze and tape covering the wound to isolate the wound cavity and the outside air. During long-term treatment, dust and bacteria in the air easily invade the inside of the wound cavity, thereby accelerating inflammation. 4. Open passive or Active drainage causes the skin around the wound to be exposed and immersed in the drainage fluid, causing damage. 5. The passive or active drainage of the wound makes the wound cavity difficult to close and heal slowly. Therefore, further improvements are needed. Summary of the invention

 The object of the present invention is to provide a multi-functional negative pressure drainage device which can not only realize active drainage treatment of a patient's wound cavity, but also can quickly and effectively control the wound to achieve timely anti-inflammatory treatment, and is easy to operate. Safe and reliable. The adhesive type multifunctional negative pressure drainage device of the invention comprises an isolation cover body for being buckled on the wound, wherein the isolation cover body is provided with a wound anti-inflammatory liquid supply branch pipe A and a waste liquid suctioning which can extend into the wound cavity The bottom side of the isolation cover body is provided with a glue layer for contacting the surface of the human skin, wherein the upper side of the isolation cover body is provided with an operation port, and the operation port is provided with Seals.

 During work, the medical staff can open the seal first, and adjust the placement of the anti-inflammatory liquid supply branch pipe A and the waste liquid suction branch pipe B through the opening, and then seal the seal.

 The invention not only has convenient use, good sealing performance, but also is safe and reliable. DRAWINGS

 The invention will now be further described with reference to the drawings and embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, the present invention includes an isolation cover 1 for fastening to a wound. The isolation cover 1 is provided with a wound anti-inflammatory liquid supply branch A and a waste suction branch pipe which can be inserted into the wound cavity. B. The anti-inflammatory liquid enters the wound cavity from the anti-inflammatory liquid supply branch pipe A, and the wound is cleaned, and then the waste liquid is sucked out from the waste liquid to the branch pipe B. The bottom side of the isolation cover 1 is provided with a bonding layer 2 for contacting the surface of the human skin. After the isolation cover is bonded to the surface of the human skin through the adhesive layer, the isolation cover and the wound cavity form a closed space, and the outside air Isolation to prevent dust and bacteria from entering the interior of the wound cavity. At the same time, it is more important to effectively protect the normal skin tissue around the wound and control the flow of waste. In order to facilitate the operation observation and wound positioning of the medical staff, the upper side of the isolation cover body is provided with an operation port 7, and the operation port is provided with a sealing member 3.

 In order to facilitate the balance of the air pressure, the isolation cover body is further provided with a vent pipe C. In order to avoid the occurrence of a situation in which the vent pipe C is not able to balance the pressure inside and outside the damper due to excessive negative pressure, the outer end portion of the waste liquid suction branch pipe B is provided with an atmosphere bypass control valve 4. When the negative pressure in the drain is too large and a large pressure is generated on the wound, the atmospheric bypass control valve 4 disposed on the outer end of the waste suction branch pipe B can be immediately opened, and the pressure inside and outside the drain can be quickly balanced. Reduce the pain of the patient. The sealing member 3 is a sealing film adhered to the operation port, so that the drainage device and the wound cavity form a closed space to isolate the air. In order to facilitate the installation and positioning, the isolation cover body is provided with a positioning duct 6, and the wound anti-inflammatory liquid supply branch pipe A, the waste liquid suction branch pipe B and the vent pipe C are jointly inserted into the isolation cover body through the positioning pipe 6. In order to facilitate the actual operation, the wound anti-inflammatory liquid supply branch pipe A, the waste liquid suction branch pipe B and the vent pipe C are connected into a combined pipe body.

 In order to facilitate the drainage treatment of a plurality of places under the same wound, the isolation cover is provided with at least two sets of combined tubes, 12 and 13, respectively.

 The embodiment of the invention has the characteristics of safety, 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 a large Promote application value.
