Abstract

The utility model relates to a Murphy's pipe with a guide rod air inhibition valve. The cylindrical inner wall of the Murphy's pipe is provided with a funnel partition board 4, a valve body 3 on which a guide rod 6 is arranged is installed between the funnel partition board 4 and a liquid inlet 1 of the Murphy's pipe, and the other end of the guide rod 6 which is not connected with the valve body 3 is connected with a hollow flotation device 7 through a funnel hole 5 of the funnel partition board 4. A hollow cavity 8 is arranged in the flotation device 7, and a gravity block 9 or no gravity block 9 is arranged in the hollow cavity 8. The sealed and closed contact surface of the valve body 3 and the funnel partition plate 4 is a cambered surface or a plane surface.

Description

The guide air does not enter the Morphis tube of valve
[technical field] guide air does not enter the Morphis tube of valve, relates to the medical transfusion injection system medicinal liquid is introduced the device that assembling is used on the intravital tube for transfusion.
[background of invention] is present, does not still have relevant technical literature publication and report similar techniques scheme, does not also have production marketing or is used for clinical; The most approaching prior art of the present utility model is common " Morphis tube ".This utility model is different with the Morphis tube structure that common transfusion uses, and technical is the check valve-type Morphis tube that common Morphis tube is improved to a tape guide structure, is a kind of technological innovation to this class medical treatment device.
[summary of the invention] this utility model purpose is; provide a kind of air that in Morphis tube, installs additional not enter valve and board-like funnel structure; air does not enter guide post is set on the valve; the air-stopping valve door is along with the input of transfusion liquid descends gradually; close transfusion Morphis tube device at last, play preventing that air from advancing the protective effect of human body and backflow of blood.
1,2 be described as follows in conjunction with the accompanying drawings:
The guide air does not enter the Morphis tube of valve, it is characterized in that:
The cylinder bodily form inwall installing funnel dividing plate 4 of described Morphis tube, assembling valve body 3 between funnel dividing plate 4 and Morphis tube inlet 1,
On the described valve body 3 guide post 6 is set,
The other end of described guide post 6 non-connection valve bodies 3 connects hollow type buoyant device 7 by the funnel hole 5 of funnel dividing plate 4.
In the described buoyant device 7 cavity 8 is set, is provided with or is not provided with gravity block 9 in the cavity 8.
The airtight contact surface of described valve body 3 and funnel dividing plate 4 is arcwall face or plane.
It is stable and reliable that this utility model keeps that transfusion regulates, and when liquid is totally lost, can seal the funnel liquid outlet at last by valve body, prevents infused human body or prevent blood reflux stream of air admission.

[specific embodiment]
In conjunction with the accompanying drawings 1,2, the guide air does not enter the Morphis tube of valve,
The cylinder bodily form inwall installing funnel dividing plate 4 of Morphis tube,
Assembling valve body 3 between funnel dividing plate 4 and Morphis tube inlet 1,
Guide post 6 is set on the valve body 3,
The other end of guide post 6 non-connection valve bodies 3 connects hollow type buoyant device 7 by the funnel hole 5 of funnel dividing plate 4.
Cavity 8 is set in the buoyant device 7, gravity block 9 is set in the cavity 8.
The airtight contact surface of described valve body 3 and funnel dividing plate 4 is the plane,
According to the technical scheme that this description and accompanying drawing provide, according to national relevant technologies standard design processing technique, Morphis tube, funnel and valve body are selected plastic material for use, make this utility model product.
