Abstract
The utility model provides a drainage bag with continuous negative pressure compensation, which is convenient in use and has good negative pressure effects. The drainage bag is characterized in that one end of the a connecting pipe is fixedly connected with one end of a guiding pipe; the other end of the guiding pipe is connected to an liquid inlet of a negative pressure device through a one-way valve A; an liquid outlet of the negative pressure device is connected with a liquid collecting bag through a one-way valve B; an air sucking capsule and a filter venting hole are arranged on the negative pressure device, and the filter venting hole is communicated with the liquid collecting bag. The continuous and stable negative pressure is produced by continuously extruding the air sucking capsule. The two one-way valves are installed on the drainage bag, wherein the one-way valve A can prevent the liquid in the guiding pipe from flowing back, and the one-way valve B can prevent the liquid in the liquid collecting bag from flowing back to the negative pressure device, so that the stability of the negative pressure and the normal use of the drainage device are ensured. In addition, the air in the liquid collecting bag can be drained from the filter venting hole in time, so that as compared with the use of an exhaust valve, the drainage device has the advantages of no operation need and convenience in use.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of negative pressure drainage bag.
Background technology
The surgical operation negative pressure drainage is the successful important leverage of operation.Suitable negative pressure drainage can make operative region present lasting negative pressure state, plays the effect of abundant drain, and the dead space between oozing of blood, sepage and the elimination wound surface of control postoperative, the infection of prevention of postoperative are had the important clinical meaning.At present, common negative pressure drainage device structure is complicated mostly, and is difficult in use calculating drainage flow, also might drain liquid be introduced into the negative pressure generator, thereby have influence on the use of negative pressure drainage device; And these equipment are difficult to produce stable negative pressure pressure.In addition, liquid collector in use has gas and gets into, and these gases of discharge in time, so some negative pressure drainage device are equipped with air bleeding valve, solve the problem that occurs gas in the liquid collector through the opening and closing air bleeding valve, operate more loaded down with trivial details.
Summary of the invention
In order to solve the problems of the technologies described above; This utility model provides a kind of easy to use, effective lasting compensation negative pressure drainage bag of generation negative pressure; Comprise joint, the connection tube that is connected with joint, liquid-collection bag, be arranged on the floss hole on the liquid-collection bag; An end that it is characterized in that connection tube is fixedly connected with an end of conduit, and the other end of conduit is connected through check valve A on the inlet of negative pressure device, and the liquid outlet of negative pressure device is through being connected with liquid-collection bag with check valve B; Negative pressure device is provided with air-breathing windbag and filters air-vent, filters air-vent and is communicated with said liquid-collection bag.
The interface quantity of said joint is one or two.
Said liquid-collection bag adopts transparent bag, and the liquid-collection bag surface is provided with capacity marking.
The beneficial effect of this utility model is: produce the negative pressure that continues through continuously extruded air-breathing windbag, the negative pressure pressure stability of generation is equipped with two check valves; Check valve A can prevent the liquid return in the conduit, and check valve B can prevent that liquid return has guaranteed the normal use of the stable and equipment of negative pressure effect to negative pressure equipment in the liquid-collection bag; Gas in the liquid-collection bag can in time be discharged from filter air-vent; With respect to using air bleeding valve, need not operation, easy to use.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the front view of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further specified:
Like Fig. 1, shown in Figure 2, joint 1 is fixed with an end of connection tube 2, and joint 1 adopts " Y " type joint; Two interfaces are arranged, and the other end of connection tube 2 and conduit 3 are fixing, and the other end of conduit 3 is connected on the inlet of negative pressure device 5 through check valve A4; Check valve A4 only allow liquid from conduit 3 one effluents to negative pressure device 5 one sides, the liquid outlet of negative pressure device 5 is connected with check valve B6, the other end of check valve B6 is connected with liquid-collection bag 10; Check valve B6 only allow liquid from negative pressure device 5 one effluents to liquid-collection bag 10 1 sides, negative pressure device 5 is provided with and filters air-vent 9, filters air-vent 9 and is communicated with liquid-collection bag 10; Gas in the liquid-collection bag 10 can be discharged from filter air-vent 9, and air-breathing windbag 8 is connected on the negative pressure device 5, and air-breathing windbag 8 can produce pressure through extruding and recovery; Negative pressure device 5 tops are equipped with and are linked with 7, and liquid-collection bag 10 adopts transparent bag, and it is marked with capacity marking; Person easy to use observes, and the lower end of liquid-collection bag 10 is connected with floss hole 11.
During use, the interface of joint 1 is connected with conduit with drain, and drain is put into the other end of conduit and treated drain liquid; Produce negative pressure through pushing air-breathing windbag 8, make and treat drain liquid flow through successively joint 1, connection tube 2, conduit 3, check valve A4, negative pressure device 5, check valve B6, finally flow in the liquid-collection bag 10.After the use, open floss hole 11, can the liquid in the liquid-collection bag 10 be discharged.
