Description
Technical field
This utility model relates to drainage bag, especially a kind of Medical negative pressure drainage bag.
Background technology
In current surgical operation; when the hematocele hydrops of operation intracavity and transudate pass through outside drainage tube lead body by client need, often can use drainage bag and carry out negative pressure drainage, after above-mentioned drain; can prevent postoperative cavity inner product liquid inductance from contaminating, thus effectively can promote wound healing.Existing drainage bag utilizes the air in external negative pressure generator extraction drainage bag usually, and make to produce negative pressure in bag by liquid drain in drainage bag, use inconvenient operation, needs after using, to negative pressure generator cleaning and sterilizing, also to make troubles to nursery work.Existing also have a kind of drainage bag, and the elastic force utilizing the spring being in compressive state to obtain makes to produce negative pressure in bag, and drainage bag is single use, and manufacturing cost is high, and price is relatively high.
Utility model content
In order to solve the problems of the technologies described above, a kind of Medical negative pressure drainage bag that this utility model provides, simple and practical, low cost of manufacture, uses easy and convenient to handle.
To achieve these goals, the technical scheme that this utility model adopts is:
A kind of Medical negative pressure drainage bag, comprise a drainage bag, the upper end of described drainage bag is provided with drain interface, negative pressure generator is provided with in described drainage bag, described negative pressure generator is docked by the plastic shrapnel of two pieces of V-shaped concave shape and forms, a cavity is formed between two plastic shrapnels, the upper end of described cavity and drain orifice, the lower end of described cavity is open ports and is communicated with the cavity of drainage bag, be squeezed to make two plastic shrapnels when resetting and produce negative pressure suction liquid, described drain interface is also provided with steam vent be communicated with negative pressure generator, during assembling, being inverted after two pieces of plastic shrapnel combinations is fixed in drainage bag, namely in reverse V-shaped structure, upper end is most advanced and sophisticated and connects drain interface, lower end is open ports.
Preferably, described plastic shrapnel is hard elastic PVC material.
Preferably, described negative pressure generator is one-body molded by two plastic shrapnels.
Preferably, the surface of described drainage bag is provided with containing mark
Preferably, described drainage bag is provided with fixation clamp.
The beneficial effects of the utility model: the built-in employing plastic shrapnel of negative pressure drainage bag forms the negative pressure generator of band cavity, the V-shaped structure of negative pressure generator is more convenient for hand-held, produce negative pressure process to assist without the need to relying on the elastic components such as outside negative pressure device or spring, structure more simplifies, more reliably practical, use easy to operate, produce negative pressure rapid, manufacture easily simple, be conducive to saving cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Fig. 1 is the Facad structure schematic diagram of drainage bag of the present utility model;
Fig. 2 is the transverse sectional view in Fig. 1.
Detailed description of the invention
Shown in seeing figures.1.and.2, a kind of Medical negative pressure drainage bag that this utility model provides, comprise a drainage bag 1, the upper end of described drainage bag 1 is provided with drain interface 3, is provided with negative pressure generator in described drainage bag 1, and described negative pressure generator is docked by two pieces of V-shaped plastic shrapnels 2 and forms, concrete, plastic shrapnel 2 is concave structure, and the concave side of two plastic shrapnels 2 is spliced relatively, makes to form a cavity between two plastic shrapnels 2.During assembling, two pieces of plastic shrapnels 2 combine rear inversion and are fixed on tip position in drainage bag 1, namely in reverse V-shaped structure, upper end is most advanced and sophisticated and is communicated with drain interface 3, lower end is open ports and is communicated with the cavity of drainage bag 1, and described drain interface 3 is provided with steam vent 4 and is communicated with negative pressure generator, and this steam vent 4 is unidirectional air-stopping valve, namely the air extruding drainage bag 1 during negative pressure generator is discharged from steam vent 4, but cannot suck air from steam vent 4 and enter drainage bag 1.
The plastic shrapnel 2 of above-mentioned employing is hard elastic PVC material, and two plastic shrapnel 2 integrated injection moldings, make overall structure have good elastic force, more solid and reliable, produces and more easily realizes.
The conveniently use of nursing staff, arranges containing mark on the surface of drainage bag 1, can be measured by scale; On drainage bag 1, be provided with fixation clamp in addition, drainage bag 1 can be fixed on specific position by fixation clamp, avoid disturbed, convenient operation.
During use, shutoff drain interface 3, extruding negative pressure generator, make plastic shrapnel 2 compressive deformation of both sides, the air in drainage bag 1 is discharged from steam vent 4, then connect drainage tube and drain interface 3, plastic shrapnel 2 resets and makes drainage bag 1 expand generation negative pressure by the hematocele hydrops in human body or liquid body exudate suction drainage bag 1 under elastic force effect, produce negative pressure process to assist without the need to relying on the elastic components such as outside negative pressure device or spring, structure more simplifies, more reliably practical
The built-in employing plastic shrapnel 2 of negative pressure drainage bag forms the negative pressure generator of band cavity, the V-shaped structure of negative pressure generator is more convenient for hand-held, rely on the reseting elasticity of plastic shrapnel 2 self to prop up bag to make to produce negative pressure in bag, use easy to operate, generation negative pressure is rapid, manufacture easily simple, be conducive to saving cost.
Above-described structure, just preferred embodiment of the present utility model, this utility model is not limited to the structure of above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
