Description

A wound sealing dressing with double tubes

technical field

The utility model belongs to medical equipment, in particular to a wound sealing dressing with double tubes which is directly in contact with the wound surface of a human body.

Background technique

In 1992, German medical doctor Wim Fleischmann pioneered the method of combining wound sealing with traditional negative pressure drainage to promote wound healing. It was quickly promoted in Europe, America and other places. It passed FDA certification and was named VAC technology, which revolutionized wound treatment. Sexual changes. But so far, there are only a few large hospitals in China, and the required instruments and special dressings are all imported, and the price is extremely expensive. The current VAC operation is to debride the wound first, then temporarily insert the drainage tube into a sponge or wrap the drainage tube with a gauze dressing, place it on the wound surface, seal it with a film, and continue the negative pressure suction treatment. The operation is inconvenient and time-consuming, and the sealing effect is unstable. And there is only one drainage tube, so the wound cannot be infused with medicine at the same time. In particular, the materials are expensive and cannot meet the requirements of serving the vast grassroots medical services in my country, which restricts the popularization and application of this technology in my country.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art, and provide a wound sealing dressing with double tubes, which is simple in structure and easy to operate, and is conducive to popularization and application in various types of hospitals, including grassroots and rural medical units.

The technical scheme of the utility model is achieved in that:

The utility model comprises non-stick gauze, a polyurethane sponge is arranged on the non-stick gauze, a silica gel film is arranged on the polyurethane sponge, a drip tube and a drainage tube respectively pass through the silica gel film, inserted into the polyurethane sponge, and the drip tube left in the polyurethane sponge Side holes are arranged on the drainage tube.

The polyurethane sponge has a thickness of 1.5-2.0 cm and a pore diameter of 400-600 μm.

There are several side holes around the end of the drainage tube, the diameter of the side holes is 0.2-0.3 cm, and the interval is 2.0 cm.

A medical patch is pasted on the silica gel membrane.

Materials such as described polyurethane sponge refer to my country's medical device biological evaluation standard and test method (GB/T 16886), adopt L929 mouse fibroblast cell strain in vitro cytotoxicity test, carry out biosafety with Kunming mouse, guinea pig, New Zealand rabbit sex evaluation.

The utility model has high quality and low price; the structure is simple, and the silicone film is integrated with the drip tube and the drainage tube. Side hole, don't worry about the direction change of the side hole, and more ensure the effect of negative pressure drainage; 3) The drip tube can deliver medicine to the wound at the same time as the negative pressure treatment, if the drainage tube is blocked for some reason, the drip tube can also be used as a drainage tube Using it improves the utilization rate of the dressing; the wound surface is easy to seal, and only needs to use a medical film to seal the silicone membrane and the periwound tissue when using it, the effect is good, and it is not easy to leak air.

Description of drawings

Accompanying drawing is the structural representation of the utility model;

Below in conjunction with accompanying drawing, the content of the present utility model is described in further detail.

Detailed ways

Referring to the accompanying drawings, a polyurethane sponge 4 is arranged on the non-stick gauze 5, and a silicone membrane 3 is arranged on the polyurethane sponge 4. The drip tube 1 and the drainage tube 2 pass through the silicone membrane 3 respectively, are inserted in the polyurethane sponge 4, and stay in the polyurethane sponge. The infusion tube 1 and the drainage tube 2 in the 4 are provided with side holes 7, and the silicone film 3 and the periwound skin are pasted and closed with a medical sticking film 6. The polyurethane sponge has a thickness of 1.5-2.0 cm and a pore diameter of 400-600 μm. There are 8 to 10 side holes around the end of the drainage tube with a diameter of 0.2 to 0.3 cm and an interval of 2.0 cm.

When in use, first debride the wound surface and lay a layer of non-stick gauze 5 on the bottom of the wound; cut the polyurethane sponge 4 and the silicone film 3 according to the wound surface, which can slightly exceed the edge of the wound; move the polyurethane sponge 4 and the silicone film 3 to the wound surface, and use a medical sticky film 6 Paste the silicone membrane 3 and the periwound skin for closure. The drainage tube 2 is connected to the negative pressure drainage bottle, and the negative pressure value of the instrument is adjusted to start treatment (recommended -120mmHg). When intending to drip medicine to the wound surface, the drip tube 1 can be connected with the infusion set for drip administration. If the drainage tube 2 is blocked for some reason, the drip tube 1 can be used as the drainage tube to improve the utilization rate of the dressing.
