Abstract
The utility model provides a negative pressure drainage instrument and belongs to the technical field of a medical appliance. The negative pressure drainage instrument structurally comprises a drainage bottle, a bottle cap, a drainage tube and a solid content filter bag, wherein the drainage bottle is in threaded sealed connection with the bottle cap; the bottle cap is in sealed inserted connection with drainage tube; one end of the drainage tube is arranged outside a bottle body, and the other end extends into the bottle and is connected with a bag mouth of the solid content filter bag; the bottom part of the drainage bottle is communicated with a negative pressure tube which is provided with a check valve; one end of the negative pressure tube is connected with a negative pressure aspirator; the negative pressure tube between the check valve and the drainage bottle is also provided with an exhaust valve; and the drainage bottle is transparent. Objects drained by the negative pressure drainage instrument are directly collected in the solid content filter bag, liquid flows into the drainage bottle to be collected through the solid content filter bag, and solid contents are stopped and filtered in the solid content filter bag, so that the solid contents cannot be mixed with drainage liquid, the solid contents and the drainage liquid can be treated respectively, and the pipeline blockage cannot be caused.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of depression drainage device.
Background technology
General, the negative pressure channel that is used for negative pressure drainage device clinically at present all is that series connection is through, for some common disorder patients or infectious disease patient, the organ that is attracted can produce physiological juice and secretions, juice is convenient to collection and treatment, but how relatively secretions thickness, physiological semisolid drain appears sometimes, even blocking pipeline, cause unnecessary trouble, this brings to a certain extent challenge for medical personnel and medical care equipment, then need need to be resolved hurrily.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of depression drainage device is provided.
The technical solution of the utility model realizes in the following manner, this depression drainage device, its structure comprises drainage bottle, bottle cap, drainage tube, solid content filter bag, drainage bottle is connected with the bottle cap thread seal, and the sealing cross-under has drainage tube on the bottle cap, and drainage tube one end is arranged on outside the bottle, the other end probes into to bottle and with solid content filter bag bag mouth and is connected, the drainage bottle bottom is communicated with the negative pressure pipe, and the negative pressure pipe is provided with check valve, and negative pressure Guan Yiduan is connected with the negative pressure-pumping device.
Also be provided with on the negative pressure pipe between check valve and the drainage bottle and unload air valve.
Drainage bottle adopts transparent bottle drainage bottle.
The beneficial effect that this utility model is compared with prior art produced is:
The suction action of this depression drainage device by the negative pressure-pumping device makes and produces negative pressure in the drainage bottle, and unidirectional breather valve prevents that gas backstreaming from advancing drainage bottle, makes and keeps negative pressure in the drainage bottle always, thereby realize negative pressure drainage.The object that drains is directly collected in the solid content filter bag, the liquid part then sees through the solid content filter bag and flow into the drainage bottle collection, and solid content matter is then filtered in the solid content filter bag by resistance, thereby can not mix with drain liquid, it can be handled respectively with drain liquid, can not cause pipeline blockage.Drainage bottle adopts the hyalomitome material, can make medical personnel observe directly color and other characteristics of the object that drains, thereby come further diagnose medical conditions.
