Abstract
The utility model relates to the field of medical devices, in particular to a disposable negative pressure drainage device. The disposable negative pressure drainage device is characterized in that: a liquid drainage bottle, a suction bottle and an expandable ball are communicated; a one-way valve is arranged in a negative pressure ball, and the negative pressure ball is extruded to enable air to go out only, so that negative pressure is generated in the liquid drainage bottle, and the liquid drainage bottle sucks drainage liquid of a focus through a liquid drainage pipe.
Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of disposable use depression drainage device.
Background technology
The medical disposable use depression drainage device of prior art is more complicated all, and volume is bigger.
Summary of the invention
Goal of the invention of the present utility model is to overcome with above-mentioned existing problem, and a kind of a kind of disposable use depression drainage device simple and reasonable for structure, well behaved is provided.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: disposable use depression drainage device, mainly form by template pincers, negative pressure ball, discharge opeing bottle, suction bottle, expanded spheres, discharging tube, puncture needle.The template pincers are transferred to the closed position, discharge opeing bottle, suction bottle are in vacuum state, push negative pressure ball repeatedly, owing to be provided with check valve in the negative pressure ball, air can only go out and can not advance, make and produce negative pressure in discharge opeing bottle, the suction bottle, and the expanded spheres that is located in the suction bottle is to be made by the thin-walled rubber of stoking, in suction bottle under the effect of negative pressure, pressure balance is kept in the air inlet air inlet, and expanded spheres is expanded rapidly, when expanded spheres is slightly run into the suction bottle wall, stop to push negative pressure ball, finish the pressure accumulation process.The position of when using, the template pincers being transferred to out, expanded spheres is slowly shunk by air inlet, makes to produce negative pressure in the discharge opeing bottle, and the discharge opeing bottle reaches the function that focus realizes attracting discharge opeing by discharging tube.Open leakage fluid dram and pour out the liquid that is attracted to, building leakage fluid dram repetition said process realization attraction discharge opeing again.
The utlity model has following advantage:
1. rational in infrastructure, volume is little.
2. do not need electric energy.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings 1, structure of the present utility model is done to describe further: this disposable use depression drainage device clamp by 1 template, and 2 discharge opeings are covered, 3 negative pressure balls, 4 discharge opeing bottles, 5 suction bottles, 6 expanded spheres, 7 air inlets, 8 discharging tubes, 9 puncture needles, 10 check valves are formed.Discharge opeing bottle 4, suction bottle 5, expanded spheres 6 communicate, being provided with check valve 10 extruding negative pressure balls 3 air in the negative pressure ball 3 can only go out and can not advance, discharging tube 8 is connected with discharge opeing bottle 4, template pincers 1 are housed between discharging tube 8 and the discharge opeing bottle 4, expanded spheres 6, air inlet 7 communicate, and the other end of discharging tube 8 is connected with puncture needle 9.
