Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The utility model discloses the most crucial design lies in:
referring to fig. 1 to 2, the main structure of the medical negative pressure drainage device of the present invention includes a bottle cap 1, an inner container 2, and a bottle body 3, wherein a liquid inlet 11 and a liquid outlet 12 are disposed above the bottle cap 1, the liquid inlet 11 is connected to a suction head (not shown) through a conduit 5, and the lower end of the liquid outlet 12 is further connected to an overflow valve 13. A sealing groove is arranged below the bottle cap 1 and is connected with the edge of the upper end of the bottle body 3 to form a closed structure. The side of the bottle body 3 is provided with a three-way pipe 4, one inlet of the three-way pipe 4 is communicated with the bottle body 3, the other inlet of the three-way pipe 4 is communicated with the liquid outlet 12 through a conduit 5, the outlet of the three-way pipe 4 is communicated with a negative pressure device (not shown in the figure) through the conduit 5, and the bottle body 3 is also provided with a volume scale mark 31 for observing the liquid level. The top of inner bag 2 links to each other with the bottom surface of bottle lid 1 is fixed, and the junction is sealed and is handled in order to prevent gas leakage, and the external diameter of inner bag 2 is less than the internal diameter of bottle 3, can supply inner bag 2 to accept in the bottle 3, and the preparation material of inner bag 2 is soft material, and the place that inner bag 2 is close to the bottle lid is equipped with the screw thread, can increase the frictional force of inner bag 2 and 3 inner walls of bottle, increases the fastness.
The utility model discloses a theory of operation does: the negative pressure device is started to pump air to the outlet of the three-way pipe 4 to form negative pressure, the negative pressure enters the inner container 2 through the guide pipe 5 through one inlet of the three-way pipe 4, waste liquid such as phlegm, pus and blood generated after the operation of a patient is sucked by the suction head and flows into the inner container 2 through the guide pipe 5 to be collected. Negative pressure can reduce the differential pressure between bottle 3 and the inner bag 2 in getting into bottle 3 through the other import of three-way pipe 4 simultaneously, prevents that inner bag 2 shrivelled.
The utility model discloses an among the negative pressure drainage ware be disposable article, can together abandon the inner bag 2 of collecting full waste liquid and the bottle lid 1 of integral type, leave bottle 3 and place the high pressure steam cooker in 121 ℃ and disinfect.
The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
