Abstract
The utility model discloses a wound surface enclosed dressing with two tubes. A polyurethane sponge is arranged on non-sticky gauze, a silica gel membrane is arranged on the polyurethane sponge, an instillation tube and a drainage tube both pass through the silica gel membrane to be inserted into the polyurethane sponge, and side holes are formed on both the instillation tube and the drainage tube inside the polyurethane sponge. The wound surface enclosed dressing has the advantages of simple structure and convenient operation, and is in favor of being generalized or used in all types of hospitals including primary level and rural medical institutions.
Description
Technical field
This utility model belongs to medical apparatus and instruments, particularly directly and the human body wound surface contacted a kind of with the airtight dressing of two-tube wound surface.
Background technology
1992, Germany's doctor of medicine Wim Fleischmann initiative combines the method that promotes wound healing with the wound surface sealing with traditional negative pressure drainage, very fast in the popularization of ground such as America and Europe, authenticates by FDA, and being named as the VAC technology, it makes Wound treating that revolutionary variation take place.But so far, domestic only have several families large hospital to carry out, required instrument and the equal dependence on import of special-purpose dressing, and price is very expensive.Present VAC technical operation is at first wound debridement, drainage tube is inserted sponge then temporarily or holds drainage tube with gauze dressing, places wound surface, pad pasting sealing, continuous negative pressure suction treatment.Operation inconvenience and time-consuming, the sealing effect instability.And a drainage tube is only arranged, simultaneously wound surface instillation Drug therapy.Especially material expensive can not satisfy the requirement for the vast primary care service of China, has restricted this technology applying in China.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, provides a kind of with the airtight dressing of two-tube wound surface, simple in structure, easy to operate, helps comprising vast basic unit and the popularization and application of rural medical treatment unit in all types of hospitals.
The technical solution of the utility model is achieved in that
This utility model comprises anti-adhesive gauze, polyurethane sponge is set on anti-adhesive gauze, pellosil is set on the polyurethane sponge, drip tube and drainage tube pass pellosil respectively, in the insertion polyurethane sponge, stay on interior drip tube of polyurethane sponge and the drainage tube side opening all is set.
Described polyurethane sponge thickness is 1.5-2.0cm, and the aperture is 400-600 μ m.
Around the end of drainage tube several side openings, side opening aperture being arranged is 0.2～0.3cm, at interval 2.0cm.
Post medical pad pasting on the described pellosil.
Materials such as described polyurethane sponge are with reference to China's medical apparatus and instruments biological assessment standard and test method (GB/T 16886), adopt the test of L929 l cell strain vitro cytotoxicity, carry out the biological safety evaluation with kunming mice, Cavia porcellus, new zealand rabbit.
This utility model is of fine quality and inexpensive; Simple in structure, pellosil and drip tube, drainage tube are integrated, and drip tube, drainage tube have inserted sponge when dispatching from the factory, and simplify the treatment operation, and around the drip tube, drainage tube side opening are arranged all, do not worry that the side opening direction changes, and guarantees the negative pressure drainage effect more; 3) drip tube can be in negative pressure treatment administration in wound, stop up for some reason as drainage tube, drip tube also can be worked as the drainage tube use, has improved the utilization rate of dressing; Wound surface is easy to sealing, only need and create the week tissue with medical pad pasting sealing pellosil during use, and is effective, is difficult for leaking gas.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Below in conjunction with accompanying drawing content of the present utility model is described in further detail.
The specific embodiment
Shown in accompanying drawing, polyurethane sponge 4 is set on the anti-adhesive gauze 5, pellosil 3 is set on the polyurethane sponge 4, drip tube 1 and drainage tube 2 pass pellosil 3 respectively, insert in the polyurethane sponge 4, stay on drip tube 1 in the polyurethane sponge 4 and the drainage tube 2 side opening 7 all is set, seal with medical pad pasting 6 stickups between pellosil 3 and all skin of wound.Described polyurethane sponge thickness 1.5-2.0cm, aperture 400-600 μ m.Around the end of drainage tube 8～10 side openings are arranged, side opening aperture 0.2～0.3cm, 2.0cm at interval.
During use, at first wound surface debridement, wound end shop one deck anti-adhesive gauze 5; Cut out polyurethane sponge 4, pellosil 3 by wound surface, can slightly exceed edge of wound; Polyurethane sponge 4, pellosil 3 move to wound surface, paste pellosil 3 with medical pad pasting 6 and seal with all skin of wound.Drainage tube 2 connects negative pressure drainage vessel, adjustment instrument negative pressure value begin treatment (recommend-120mmHg).When plan was dripped medicine to wound surface, drip tube 1 can link to each other dropleting medicine-feeding with transfusion device.As drainage tube 2 occurs and stop up for some reason, can select for use drip tube 1 to be used as drainage tube and use, improve the dressing utilization rate.
