Abstract
The utility model discloses a disposable negative pressure drainage device, which comprises a hard transparent plastic bottle which is provided with a hook, and a plastic liquid storing bag, wherein an interface of a negative pressure source and an interface of a drainage tube are arranged on the plastic bottle, and a liquid outlet is arranged on the lower end of the plastic bottle; the liquid outlet is connected with a liquid discharging tube, a unidirectional valve is arranged on the outlet end of the liquid discharging tube and the liquid discharging tube is communicated with the liquid storing bag. The utility model has the advantages of simple structure, convenient use and disposable use; cross infection can be effectively avoided. The utility model can be widely used for clinical drainage for body cavities of patients.
Description
Technical field this utility model belongs to medical treatment and nursing utensil technical field, relates to a kind of depression drainage device.
Background technology is present, the depression drainage device that hospital clinical uses, and mainly by after two high capacity vial series connection, an end connects negative pressure source, and the other end is communicated with patient's body lumen by drainage tube, and liquid such as the intravital dope of patient, ascites are drained in the vial.Each drain finishes, and all need be cleaned, sterilize vial by medical personnel, bothersome effort, and the danger that cross infection takes place is arranged.
The summary of the invention the purpose of this utility model provides a kind of disposable depression drainage device of avoiding cross infection, to remedy the deficiencies in the prior art.
The disposable depression drainage device of this utility model comprises hard transparent plastic bottle and plastics liquid storing bag that band is linked up with, and plastic bottle is provided with negative pressure source interface and drainage tube interface, and its lower end is provided with liquid outlet; Connect discharging tube on the liquid outlet, the port of export of discharging tube is provided with check valve; Discharging tube is communicated with liquid storing bag.
In order to grasp drainage flow, said liquid storing bag is marked with scale.
This utility model use simple in structure, easy to use, disposable can effectively avoid intercrossing to infect, and it is clinical to be widely used in the patient's body lumen drain.
Appended drawings is this utility model structural representation.
The specific embodiment with reference to the accompanying drawings, the disposable depression drainage device of this utility model comprises the hard transparent plastic bottle 1 and the plastics liquid storing bag 7 of band hook 4, plastic bottle 1 is provided with negative pressure source interface 3 and drainage tube interface 2, its lower end is provided with liquid outlet 5; Connect discharging tube 6 on the liquid outlet 5, the port of export of discharging tube 6 is provided with check valve 8, and is open-minded downwards, upwards closes; Discharging tube 6 is communicated with liquid storing bag 7, and liquid storing bag 7 is marked with scale.
When this utility model uses, plastic bottle 1 is hung on the transfusion stand, and negative pressure source interface 3 is connected with drainage tube with negative pressure source respectively with drainage tube interface 2, can carry out the body cavity drain.After negative pressure source started, the check valve 8 of discharging tube 6 ports of export was subjected to suction function and closes automatically, and drainage tube just can suck drain liquid in the plastic bottle 1.The liquid that enters in the plastic bottle 1 flows to plastic bottle 1 bottom by deadweight, enters in the discharging tube 6 from liquid outlet 5.Fluid accumulation in discharging tube 6 is to certain altitude, and the pressure of fluid column is with one-way valve opens, and drain liquid enters in the liquid storing bag 7.As the drainage tube obstruction takes place, and during plastic bottle 1 intrinsic pressure increasing, the check valve 8 of discharging tube 6 ports of export is promptly closed automatically, and the drain liquid in the liquid storing bag 7 can not gone in the plastic bottle 1 by suck-back.The depression drainage device of this structure adopts 250～500ml because the volume of plastic bottle 1 is general, and selects for use rigid plastics to make, and is cheap, can disposablely use.
