Abstract
The utility model relates to a Murphy's transfusion tube with a cap-skirt ball valve non-return structure, which has the structure characteristics that the cylindrical inner wall of a Murphy's bottle body is additionally provided with an arched funnel 5, and a non-return ball valve 3 with a cap-skirt guide vane 4 is installed between the arched funnel 5 and a fluid inlet 1. The arched funnel 5 is provided with at least one fluid outlet 6, the non-return ball valve 3 is a small closed type hollow ball with an equatorial trough, and the equatorial trough of the non-return ball valve 3 is provided with the cap-skirt guide vane 4. The periphery of the cap-skirt guide vane 4 is provided with one or more than one overflow port 8. The utility model keeps the stabilize and reliable regulation of the transfusion of a Murphy's bottle and utilizes the small non-return ball to seal a fluid outlet 7 after transfusion to prevent air from entering human bodies. Simultaneously, blood can be effectively prevented from flowing back into the transfusion tube.
Description
The Mo Feisi tube for transfusion of the non-return structure of [technical field] band cap-skirt type ball valve relates to the medical transfusion injection system medicinal liquid is introduced the device that assembling is used on the intravital tube for transfusion.
[technical background] 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; Because this utility model is different with existing common transfusion " Morphis tube " structure, technical have a bigger improvement, can't compare on the structure, and this utility model 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 in the Mo Feisi bottle cylinder shape inner wall install the arc funnel additional, between arc funnel and the inlet, assemble the Mo Feisi infusion set of a band cap skirt guiding wing check ball valve, check ball valve is along with the last input of transfusion liquid descends gradually, and last check ball valve is closed the Mo Feisi tube for transfusion.
1,2 all figure are described as follows in conjunction with the accompanying drawings:
See Fig. 1, the Mo Feisi tube for transfusion of the non-return structure of band cap-skirt type ball valve relates to a kind of agent structure feature and installs arc funnel 5 additional by Mo Feisi bottle 2 cylinder shape inner walls, between arc funnel 5 and the inlet 1, assemble the infusion set of check ball valve 3 formations of a band cap skirt guiding wing 4
Described arc funnel 5 has a liquid outlet 6 at least,
Described check ball valve 3 is the closed hollow bead of a band colpus,
The colpus assembling cap skirt guiding wing 4 of described check ball valve 3,
See Fig. 2-a, b, c, the periphery of described cap skirt guiding wing 4 is offered one or more than one overfall 8.
This utility model keeps the stable and reliable of Mo Feisi bottle transfusion adjusting, and can seal liquid outlet 7 after liquid is totally lost by non-return bead, prevents the air admission human body, effectively prevents blood reflux inflow tube for transfusion simultaneously.

[specific embodiment]
See Fig. 1, the Mo Feisi tube for transfusion of the non-return structure of this utility model band cap-skirt type ball valve relates to agent structure and installs arc funnel 5 additional by Mo Feisi bottle 2 cylinder shape inner walls,
Between arc funnel 5 and the inlet 1, the check ball valve 3 of assembling one band cap skirt guiding wing 4, arc funnel 5 has a liquid outlet 6,
Check ball valve 3 is the closed hollow bead of a band colpus,
The colpus assembling cap skirt guiding wing 4 of check ball valve 3,
See Fig. 2-a, b, c, the periphery of described cap skirt guiding wing 4 is offered 4 overfalls 8.
According to this description and the given technical scheme of accompanying drawing, according to national relevant technologies standard design processing drawing and description of the process, select medical-grade plastics material for use, can make this utility model product.
