AI Technical Summary
When treating patients' legs, the existing polyurethane closed trauma negative pressure drainage kits have poor sealing properties due to the dense leg hair, which affects the aspiration of tissue fluid.
A negative pressure wound drainter is designed, which uses a latex and expansion tube with a latex material. It is fixed to the patient's legs through the expansion tube's expansion, and negative pressure is formed by the negative pressure ball to extract the tissue liquid.
The device can be effectively fixed on the patient's legs. Even if the legs are thickly hairy, it can maintain good sealing and improve the suction efficiency of tissue fluid.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a negative pressure wound drainer. Background Art
[0002] As we all know, the main business scope of the Department of Critical Care Medicine is: rescue and continuous life support for critically ill patients; treatment and organ function support for patients with multiple organ dysfunction; prevention and treatment of multiple organ dysfunction syndrome.
[0003] Among them, polyurethane closed trauma negative pressure drainage suits are often used for wound treatment. Polyurethane closed trauma negative pressure drainage suits are an advanced wound healing treatment system for treating various acute wounds and chronic difficult-to-heal wounds. It is mainly composed of extension tubes, adsorption pads, medical foam, disposable sterile dressings, straight-through, three-way and stop-flow clamps.
[0004] However, when treating patients' legs, since many patients have dense leg hair, using a disposable sterile dressing to fix the device results in poor airtightness, which affects the suction of tissue fluid. Utility Model Content
[0005] 1. Technical issues to be solved
[0006] In view of the deficiencies in the prior art, the utility model provides a negative pressure wound drain device, which solves the problems mentioned in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a negative pressure wound drainer, comprising a fixed tube, an adsorption pad is installed inside the fixed tube, both ends of the fixed tube are connected to expansion tubes, each expansion tube is connected to an exhaust pipe, each exhaust pipe is installed with a packaging cap, each expansion tube is connected to an air intake pipe, each air intake pipe is installed with a one-way valve, a connecting tube is connected to the middle of the outer wall of the fixed tube, the connecting tube is connected to a connecting branch pipe, a sealing plug is installed at one end of the connecting branch pipe, a clamp is installed on the connecting tube, and a negative pressure ball is installed on the connecting tube.
[0009] Furthermore, the fixing tube is made of latex.
[0010] Furthermore, each expansion tube is made of latex.
[0011] Furthermore, each exhaust pipe is provided with an external thread, each packaging cap is provided with an internal thread inside, each exhaust pipe is connected to each packaging cap through threads, and a rubber pad is installed between each exhaust pipe and each packaging cap.
[0012] Furthermore, the sealing plug is made of rubber.
[0013] Furthermore, one end of the connecting tube is connected to a fluid accumulation bag.
[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a negative pressure wound drainage device, which has the following beneficial effects:
[0016] The negative pressure wound drainer is constructed by arranging expansion tubes made of latex at both ends of a fixed tube made of latex, and using a syringe to connect the air inlet tube to expand the two expansion tubes, so that the fixed tubes can be fixed on the patient's legs. Even if the patient's legs are densely haired, the expansion tubes can fit better with the legs, and then by pressing the negative pressure ball, negative pressure is formed in the fixed tube to extract tissue fluid.
