Abstract

The invention relates to a negative pressure drainage device, comprising a bracket, wherein the bracket is provided with a drainage bottle which is internally provided with a drainage bag, a cover of the drainage bag is provided with two opening joints, one opening joint is connected with the drainage bottle by using a conduit and a multiway joint, and a one-way valve is arranged in the drainage bag of the opening joint provided with the drainage bottle. The device is simple in structure and can be used repeatedly, and the drainage bag is timely destroyed after used once so as to achieve the purpose of better sanitation; the flow of drained body fluid can be clearly learned through scale marks on the drainage bottle; and the adoption of the one-way valve facilitates to prevent the fluid from being introduced into an suction unit when the drainage bag is filled with the fluid.

Description

A kind of negative pressure drainage device

Technical field

The present invention relates to a kind of medical apparatus and instruments, especially relate to a kind of negative pressure drainage device.

Background technology

The surgical operation negative pressure drainage is the successful important leverage of operation.Suitable negative pressure drainage can make the art district be lasting negative pressure state, can play the effect of abundant drain.To the dead space between oozing of blood, sepage and the elimination wound surface of control postoperative, the infection of prevention of postoperative has the important clinical meaning.At present, complicated mostly in the negative pressure drainage device structure of using, and all be difficult in practice calculating drainage flow, and body fluid might be introduced into when in use in the generation means for applying negative, next time is used this device in influence, and is unhygienic.

Summary of the invention

Technical problem to be solved by this invention provides a kind of simple in structure, the negative pressure drainage device of health safe in utilization.

The present invention solves the technical scheme that its technical problem takes: a kind of negative pressure drainage device, comprise support, support is provided with drainage bottle, be provided with drainage bag in the described drainage bottle, the lid of drainage bag is provided with two open joints, one of them open joint links to each other with drainage bottle with Multidirectional connector with conduit, is provided with check valve in the drainage bag of this open joint.

For in the negative pressure drainage device use, because the body fluid that will drain is more, do not need more changing device, can constant drainage, described drainage bag and the drainage bottle outside that has check valve is provided with drainage bag and the drainage bottle of not being with check valve, and manage the open joint that connects two drainage bags respectively with " U " shape, connect with conduit between the drainage bottle; Described not with the drainage bag of check valve and drainage bottle at least one.

This device also can adopt another kind of structure to producing negative pressure in drainage bag and the drainage bottle: described Multidirectional connector is connected with drainage bottle respectively by conduit and replaces connecting with conduit between the drainage bottle.

In order clearerly to understand the concrete flow of the body fluid that is drained, described drainage bottle adopts transparent material to make, and is provided with graduation mark on the surface of drainage bottle.

Advantage of the present invention is: this apparatus structure is simple, and can use repeatedly, and drainage bag was used once and in time destroyed, and was much cleaner; There is graduation mark can clearly know the flow that drains body fluid on the drainage bottle; Adopt check valve to avoid when liquid is full of drainage bag, being introduced in the suction pump.

The specific embodiment

A kind of as shown in Figure 1 negative pressure drainage device, comprise support 1, support 1 is provided with drainage bottle 2, be provided with drainage bag 8 in the described drainage bottle 2, the lid of drainage bag 8 is provided with two open joints 3, one of them open joint 3 usefulness conduit 7 links to each other with drainage bottle 2 with Multidirectional connector 5, is provided with check valve 6 in the drainage bag 8 of this open joint 3; Described drainage bag 8 and drainage bottle 2 outsides that have check valve 6 are provided with drainage bag 8 and the drainage bottle 2 of not being with check valve 6, and connect the open joint 3 of two drainage bags 8 respectively with " U " shape pipe 4, between the drainage bottle 2 with conduit 7 series connection; Described not with the drainage bag 8 of check valve 6 and drainage bottle 2 at least one; Described drainage bottle 2 adopts transparent material to make, and is provided with graduation mark on the surface of drainage bottle 2.

The present invention also has another kind of embodiment to replace between the drainage bottle 2 with conduit 7 series connection for described Multidirectional connector 5 is connected with drainage bottle 2 respectively by conduit 7.

One end of Multidirectional connector 5 connects suction pump, by suction pump to producing negative pressure in drainage bottle 2 and the drainage bag 8, drainage bag 8 is by 4 series connection of " U " shape pipe, drainage bottle 2 is connected by conduit 7 or directly is connected with Multidirectional connector 5, make each drainage bottle 2 and drainage bag 8 all produce negative pressure, drain body fluid, and check valve 6 is arranged at an end of Multidirectional connector 5 connection opening joints 3, its effect is to stop to be introduced into suction pump when filling body fluid.

Have in the item of using this negative pressure drainage device to note: use the back to note keeping properly, cleaning up; It is good, shady and cool dry that the negative pressure drainage bag should be stored in performance of ventilating, and relative humidity is not more than in the environment of 80% no etchant gas; Forbid heap to be pressed, prevent to puncture the suction drainage bag; Drainage bag with after in time destroy.
