Abstract
The utility model relates to a negative pressure drainage bottle. Liquid in a bottle draining is more convenient and sanitary through adding a liquid outlet on a bottle body. In addition, the cross section of bottle body is converted into an elliptical shape from a circular shape which enhances a negative pressure in the bottle when the negative pressure drainage bottle is extruded and prevents the bottle body from being damaged. The utility model has the advantages of reasonable design, simple structure, sanitation and convenience. The utility model is suitable for the drainage uses of all stages of hospitals.
Description
The utility model relates to a kind of medical drainage apparatus, particularly a kind of negative pressure drainage vessel.
Patent Office of the People's Republic of China has announced a kind of utility model patent that is called " negative pressure drainage vessel " on June 15th, 1988, is characterized in having air extractor duct at bottleneck inlet side cover envelope seal ring on the air extractor duct.Depression drainage device more early stage when this drainage bottle uses is convenient, but the liquid of suction still need open loam cake and just can empty, thereby trouble still when using.In addition, this drainage bottle body cross-sectional plane is generally circle, and this shape exists cracky and the not high defective of negative pressure value.
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of easy to use, health, suction effect is better and the not high disposable use negative pressure drainage vessel of cost.
Task of the present utility model is by offering liquid outlet on bottle, and ellipse finishes for the bottle of circle is changed into cross-sectional plane.
Fig. 1 is a keystone configuration scheme drawing of the present utility model, and as Figure of abstract;
Fig. 2 is the utility model bottle birds-eye view.
The utility model is described in further detail below in conjunction with drawings and Examples.
Bottle (1) at drainage bottle has liquid outlet (2), and liquid outlet has the switch (3) that clip cap or stopper etc. are made, in order to the discharging of liquid in the control bottle.The bottle upper end is inlet (4) and drainage tube (5), and the terminal check valve (6) that connects of inlet prevents that gas, liquid from flowing backwards.Inlet neck side is established deflation hole (7), its periphery is wound with elastomeric seal ring (8), and gas can only be gone out can not be advanced, because this bottle is by continuously extruded generation negative pressure, so for guaranteeing that drainage bottle can reach the high negative value and make not cracky of bottle, the cross-sectional plane of bottle is done ovalisation.Use for convenient, suspender (9) is loaded onto on bottle top, and the suspension that is used for drainage bottle is fixed.
The utility model is reasonable in design, simple in structure, owing to open the liquid outlet switch and get final product discharge liquid, has saved and has frequently got bottle and uncap, fall the trouble of liquid, uses more convenient health; Again because the bottle cross-sectional plane be an ellipse, so but the negative pressure of extrusion bottle De Genggao, and bottle cracky not.Thereby result of use is better.
Claims (4)
1, a kind of negative pressure drainage vessel is made up of the deflation hole and the peripheral seal ring that is wound with thereof of the inlet and the drainage tube of bottle and upper end thereof, the check valve that links to each other with the inlet end, inlet neck side, it is characterized in that liquid outlet is arranged on bottle.
2,, it is characterized in that having on the liquid outlet switch according to the described drainage bottle of claim 1.
3,, it is characterized in that bottle cross-sectional plane ovalize according to the described negative pressure drainage vessel of claim 1.
4,, it is characterized in that suspender is arranged on the bottle according to the described negative pressure drainage vessel of claim 1.
