Abstract

The utility model relates to a medical surgical auxiliary device which is particularly used for drainage after surgical operations. A drainage tube of the utility model is provided with an inner tube of the drainage tube, and one end of the inner tube of the drainage tube is provided with a drainage hole. Gauze is wound around the end with the drainage hole to form a cigarette shape, an outer skin layer is arranged outside the cigarette-shaped gauze, both ends of the outer skin layer are fixed, and the outer skin of the drainage tube is provided with a drainage hole. One end of the inner tube of the drainage tube is connected with a negative pressure drainage device. The drainage tube has the advantages of good tightness, large drainage areas, thorough drainage, simple manufacture, low price, and safe and convenient application; the utility model is not easy to clog up, fall off and cause infection, and is easy to popularize and apply in various primary hospitals.

Description

Negative pressure drainage tube

This utility model is a kind of medical surgical assistive device, especially for the drain behind the surgical operation.

Intraperitoneal drainage is the major measure that prevents the infection in abdominal cavity.Intraperitoneal drainage thing commonly used at present has cigarette drain, tube drainage and rubber strip drain etc.Tradition cigarette drainage tube mainly is rolled into cigarette type with several layers of gauze, and it is outside double-bags with the glove adhesive plaster, and this drainage tube easily stops up, and drainage time is lacked, and is open passive drain, only can be used for the prevention drain in abdominal cavity clinically.And the tube drainage thing is also easily stopped up conduction hole by the abdominal cavity surrounding tissue and pressurized becomes flat and influences drain.More than the shortcoming of several drains be that drain is easily blocked, easily come off, easy infection, drain is not thorough, action time is short etc.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of drainage tube that can prevent to block, come off, and can make the drain area big again, and drain is thorough, long action time, and can wash or the negative-pressure drainage tube of medication.

Technical solution of the present utility model is: this negative-pressure drainage tube has pipe in the drainage tube, Guan Yiduan is provided with conduction hole in the drainage tube, twines gauze at an end that is provided with conduction hole and becomes cigarette type, and the cigarette gauze is provided with exodermis outward, its two ends of exodermis are fixed, and the drainage tube crust is provided with conduction hole.Pipe range is in the drainage tube crust in drainage tube one end cigarette gauze and the drainage tube, and other end drainage tube crust is longer than the husky cloth of cigarette.

This utility model has following advantage compared to existing technology:

1, this drainage tube utilizes the lasting attraction and the support effect of cigarette gauze, thereby does not influence drain, long action time because of the surrounding tissue pressurized becomes flat or blocks.

2, this drainage tube is because of approaching rubber winding, sound construction, difficult drop-off with gauze writhing number layer and outside using.

3, gauze does not communicate with the external world in this drainage tube, has only an end of pipe in the drainage tube to link to each other with depression drainage device, and incision dressing keeps clean, drying, has avoided the generation of antidromicity abdominal cavity infection and complication.

4, this drainage tube not only has drainage, also can both can do preventative drain by pipe perfusion in the drainage tube, flushing medication, can do the therapeutic drain again.

5, this drainage tube negative pressure drainage, the cigarette gauze is in leather hard all the time, so initiatively drainage is strong.Drain is not subjected to the restriction of stagnant liquid position, the abdominal cavity height and the depth, and active area is big, and drain is thorough.

6, this drainage tube patient after clinical practice 102 example operations is respond well.This drainage tube is made simple, and is cheap, and application safety is convenient, easily applies at each basic hospital.

The drawing of accompanying drawing is described as follows: Fig. 1 is the drainage tube sketch map, and Fig. 2 is a pipe sketch map in the drainage tube, and Fig. 3 is an A-A profile among Fig. 1.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail.

Referring to Fig. 2, pipe (1) available length is about 30cm in the negative-pressure drainage tube, and diameter is 0.5cm silica gel tube or latex tubing, is cut into 8 of 3.0 * 0.2 conduction holes in silica gel tube one end 8cm length.Referring to Fig. 1, then with gauze in having an end 14cm length of conduction hole, twine 6 layers to caliber be 1.5cm, the thin rubber of reuse is 2 layers of gauze outsourcings, the junction cements with robber cement.Make inner cigarette gauze (4) of abdomen and the interior pipe of drainage tube (1) be longer than drainage tube crust (2) 0.5cm, abdomen outer end drainage tube crust (2) is longer than cigarette gauze (4) 1.5cm, cigarette gauze (4) is wrapped in the drainage tube crust (2) fully, the junction cements with robber cement, and only pipe (1) communicates with extraneous depression drainage device in the drainage tube.(not drawing among the figure).

Drainage tube autoclave sterilization or 70% alcohol-pickled 30 minutes are standby.In twining an end 8cm length of gauze, be cut into (3) 6 of the conduction holes of 0.3 * 0.2cm during use, after soaking, drainage tube is put into the part of patient abdominal cavity need drain with normal saline, skin 3cm is exposed at the cigarette position outside the abdominal cavity, pipe (1) connects disposable depression drainage device (peak suction is 20mmHg) in the drainage tube, start depression drainage device, can use.

If when abdomen innerlich anwenden or flushing, by silica gel tube perfusion antibiotic and normal saline.
