CN2329373Y - Foam drainage strip - Google Patents

Abstract

The utility model provides a foam drainage strip, belonging to a medical device. The strip body (1) of the foam drainage strip adopts a foam structure and can be made of foam silicon rubber. The foam drainage strip has a strong adsorbing force which is more than four times stronger than the adsorbing force of a gauze drainage. The foam drainage strip has the advantages of strong drainage capacity, good drainage effect, elasticity, deformability, small irritation to tissue, one-time usage, nontoxicity and no harm, can facilitate tissue, and particularly infected wound to grow, can be compressed with the growth of granulation tissue, can not obstructed growth, can be made into different shapes as required, can be easily disinfected, packaged and carried, and can be used in bulk.

Description

A kind of foam drainage strip

This utility model provides a kind of drain device, belongs to medical supplies.

Surgical drainage is with between tissue or the pus that gathers in the body cavity, blood or the technology of other liquid guide flow in external or splanchnocoel, and surgical drainage is the important method of treatment surgical infection.The material of drain both at home and abroad has at present: rubber drainage strip, wrinkle shape rubber drainage strip, gauze drain bar, oily yarn drainage strip, cigarette drain bar, drain rubber tube, these devices once played a significantly greater role in surgical clinical.But also there is fairly obvious shortcoming in these materials, the one, and absorption affinity is poor, and the 2nd, bigger to tissue stimulation, the 3rd, easy obstruction makes it inadequate drainage, and the 4th, sterilize, pack, carry inconvenience, the 5th, can not large quantities ofly be applied to industrial injury, war wound, earthquake wound etc.

The purpose of this utility model provides a kind of foam drainage strip, to improve absorption affinity and drainage effect, improves the convenience of using.

This utility model is achieved in that its drainage strip body is the cystose structure.

Adopt the drainage strip absorption affinity of above-mentioned structure strong, drainage effect is good, and through test, its absorption affinity is more than four times of gauze drain bar.Flexible, deformable, little to tissue stimulation, be beneficial to tissue growth, especially infected wound can be compressed with the growth of granulation tissue, makes hypertrophy not be subjected to obstacle.Can make different shape as required.Density and elasticity can change according to different needs.Can disposablely use, packing, easy to carry, and can industrial injury, war wound, large quantities of uses when earthquake is hindered take place.

Below in conjunction with description of drawings structure of the present utility model.

Fig. 1 is the sketch map of structure of the present utility model.Fig. 2-Fig. 9 has represented that respectively the drainage strip body section is shaped as the situation of circle, ellipse, hollow shape, the shape of a saddle, square, profile of tooth, gear shape and wrinkle shape.Figure 10 has represented the sketch map of a kind of embodiment of the present utility model.Figure 11 is the sketch map of another kind of embodiment.

As shown in Figure 1, the bar body (1) of a kind of foam drainage strip of this utility model is the cystose structure.

Bar body (1) is made by foam silicone rubber.Silicone rubber is nontoxic, has been used for medical domains such as shaping at present.

As Fig. 2-shown in Figure 9, the cross sectional shape of bar body (1) is circle, ellipse, hollow shape, the shape of a saddle, square, profile of tooth, gear shape or wrinkle shape.

As shown in figure 10, also has spheroplast (2) in the bottom of bar body (1).The drainage strip of this shape has enlarged adsorption area, uses in the time of can having than large space in wound inside.Outer surface at whole body can be fluted, with further expansion adsorption area.

As shown in figure 11, also has branch (3) in the bottom of bar body (1).So also be in order to enlarge its adsorption area, to improve the drain ability.

Claims (5)

1. a foam drainage strip is characterized in that, the bar body (1) of described drainage strip is the cystose structure.

2. a kind of foam drainage strip as claimed in claim 1 is characterized in that described body (1) made by foam silicone rubber.

3. as claim 1 and 2 described a kind of foam drainage strips, it is characterized in that the cross sectional shape of described drainage strip body (1) is circle, ellipse, hollow shape, the shape of a saddle, square, profile of tooth, gear shape or wrinkle shape.

4. a kind of foam drainage strip as claimed in claim 1 is characterized in that the bottom of described body (1) also has spheroplast (2).

5. a kind of foam drainage strip as claimed in claim 1 is characterized in that the bottom of described body (1) also has branch (3).
