Abstract
The utility model relates to an automatic injection sealing and opening device for an injection drip chamber. The automatic injection sealing and opening device comprises a drip chamber shell (1), and an automatic sealing cone (2) is arranged in the drip chamber shell (1). The automatic injection sealing and opening device has the advantages that when the injection in the drip chamber is about to be used up, the buoyancy of the remaining injection, providing for the automatic sealing cone, is smaller than the self gravity of the automatic sealing cone, the automatic sealing cone can move downward by means of self weight, a water outlet of the drip chamber is sealed by a lower cone of the automatic sealing cone so as to lead air and the remaining injection not to flow out, and ensure the safety of an injection ; after a liquid medicine bottle is changed, the injection can continuously drip in the drip chamber, the buoyancy of the injection, providing for the automatic sealing cone, is greater than the self gravity of the automatic sealing cone along with the increasing of the injection in the drip chamber, the automatic sealing cone can move upwards by means of buoyancy provided by the injection, the lower cone of the automatic sealing cone leaves the water outlet of the drip chamber, the water outlet of the drip chamber is opened so as to enable the injection to flow out for continuous injecting. The automatic injection sealing and opening device is simple in structure, convenient to operate and safe and reliable.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of injection dropping funnel liquid automatic sealing package opening apparatus.
Background technology
In the dropping funnel of present injection, empty, after injection has been injected, calling the nurse changes dressings, the nurse clamps rubber tube to a clip, allow and stay a part of medicinal liquid in the dropping funnel, continue again injection, so not only trouble after changing dressings, also can harm be arranged to the injector, if the nurse is too busy to do it or do not find the nurse temporarily, will be after having injected, air enters in the rubber tube, cause the injector poor because of the rubber tube inner air pressure, blood backflow enters rubber tube, even air can be brought in the blood vessel, brings danger to the injector.
Summary of the invention
The purpose of this utility model is a kind of injection of design when having injected soon, can automatic-sealed dropping funnel outlet in the dropping funnel, and make air can not run into rubber tube, cause injector's blood backflow to enter the injection dropping funnel liquid automatic sealing package opening apparatus of rubber tube.
This utility model injection dropping funnel liquid automatic sealing package opening apparatus comprises dropping funnel shell 1, is provided with automatic-sealed cone 2 in the dropping funnel shell 1, and described automatic-sealed cone 2 comprises: the balance columns 4 that lower cone 3 and lower cone 3 tops are provided with; Be provided with one deck soft material layer 5 on described lower cone 3 outer surfaces, lower cone 3 can be for hollow or solid, if hollow, then have an inlet opening 6 in the cone bottom, 6 foot has the apopore 7 that a diameter is inlet opening 6 diameter 1/4-1/3 in the inlet opening simultaneously.
The advantage of this utility model injection dropping funnel liquid automatic sealing package opening apparatus is: behind the fast sky of the injection in the dropping funnel, the buoyancy that the residue injection offers the automatic-sealed cone is less than self gravity of automatic-sealed cone, the automatic-sealed cone moves downward with regard to the deadweight by self, the lower cone of automatic-sealed cone seals the outlet of dropping funnel, air and surplus liquid can not flowed out, guarantee injector's safety; After changing medicinal liquid bottle, injection continues to be added dropwise to dropping funnel, and along with increasing of injection in the dropping funnel, the buoyancy that injection offers the automatic-sealed cone is greater than self gravity of automatic-sealed cone, the automatic-sealed cone just provides buoyancy to move upward by injection, the lower cone of automatic-sealed cone leaves the water outlet of dropping funnel, and the outlet of dropping funnel is opened, and injection is flowed out smoothly, continue injection, simple in structure, easy to operate, safe and reliable.
