Abstract
The invention relates to a disposable light shielding liquid stopping infusion apparatus drip chamber which comprises a drip tube, an upper shell and a lower base. The upper shell is composed of a light shielding upper shell body and a transparent upper shell body. The lower base is composed of a light shielding lower base body and a transparent lower base body. The disposable light shielding liquid checking infusion apparatus drip chamber further comprises a liquid stopping valve mechanism with a mechanical flow control function and arranged in the drip chamber. When a drug solution sensitive to light rays is injected in a vein infusion mode, the light shielding function is achieved; when drug infusion is ended or during the period when drug bottles are replaced, an infusion pipe is automatically sealed, the air is prevented from entering the body of a patient, blood return is avoided, the risks possibly generated due to the fact that light shielding matter affects the sight are lowered, and the working pressure of medical staff is relieved.
Description
Technical field
The present invention relates to a kind of single use lucifuge and stop liquid infusion unit titrimeter, more particularly, relate to and a kind ofly can have lucifuge function when the drug solution of venoclysis to light sensitive, medicinal liquid infusion terminates or changes a bottle gap, self-closed infusion pipeline, the single use lucifuge preventing air from entering in patient body stops liquid infusion unit titrimeter.Belong to medical sanitary technology field.
Background technology
When current patient carries out the drug solution venous transfusion to light sensitive, widely using single use light proofing infusion apparatus, ensureing that therapeutic effect serves positive role to preventing medicine from changing like this.But, because it does not have the self-closed function when medicinal liquid is totally lost, lucifuge material affects sight line again, make patient or medical personnel accurately and timely cannot grasp medicinal liquid infusion situation, there is the possibility such as vein, blood back that air enters patient, bring the hidden danger be absolutely unsafe to patient, too increase the operating pressure of medical personnel simultaneously.
Medicinal liquid is affected for preventing the lucifuge material in single use light proofing infusion apparatus material, there is the problem of drug compatibility aspect, according to supervision department's requirement, squeeze (blowing) that existing single use light proofing infusion apparatus flexible pipe and dropping funnel all have employed double-layer coextrusion moulds technique, outer is the material containing lucifuge material, and internal layer is the transparent material meeting drug compatibility requirement.The method and structure of this manufacture dropping funnel have impact on the design and implimentation of transfusion device automatic liquid-stopping function, needs to be improved.
Summary of the invention
The present invention aims to provide a kind ofly can have lucifuge function when the drug solution of venoclysis to light sensitive, and medicinal liquid infusion terminates or changes a bottle gap, self-closed infusion pipeline, and the single use lucifuge preventing air from entering in patient body stops liquid infusion unit titrimeter.
Technical scheme of the present invention is as follows:
Single use lucifuge stops liquid infusion unit titrimeter, it is characterized in that: it comprises dropper, upper shell, lower base, wherein upper shell is made up of lucifuge upper shell and transparent upper shell, lower base is made up of lucifuge lower base and transparent lower base, it also comprises the only liquid valve system that of being arranged in described dropping funnel has mechanics flow control effect, only should include a housing (dropping funnel body), the buoyancy body be arranged in dropping funnel by liquid valve system, have infusion channel in lower base, infusion channel is positioned at the below of buoyancy body.
Above-mentioned have the only liquid valve system of mechanics flow control effect to meet following condition: in infusion process, when dropping funnel inner liquid medicine liquid level is in normal level, buoyancy body is in suspended state; When transfusion terminates or changes bottle gap, buoyancy body declines, and contact with infusion channel, closed infusion channel.
The advantage of technique scheme is, 1, lucifuge upper shell and lucifuge lower base prevent light on the impact of medicine; Although 2 lucifuge Effect of Materials sight lines, possibly medicinal liquid infusion situation accurately and timely cannot be grasped, owing to stopping the self-closed function of liquid valve system when medicinal liquid is totally lost, air cannot enter the vein of patient, also can not produce blood back phenomenon, improve safety, reduce the operating pressure of medical personnel.
Further technical scheme is, described lucifuge upper shell and transparent upper shell are double-layer integrally part.
Another step technical scheme is, described lucifuge lower base and transparent lower base are double-layer integrally part.
The technical scheme of a step is again, single use lucifuge stops liquid infusion unit titrimeter, it comprises dropper, upper shell, lower base, wherein upper shell is made up of lucifuge upper shell and transparent upper shell, it also comprises the only liquid valve system that of being arranged in described dropping funnel has mechanics flow control effect, only should include a housing (dropping funnel body) by liquid valve system, be arranged on the buoyancy body in dropping funnel, infusion channel is had in lower base, infusion channel is positioned at the below of buoyancy body, it is characterized in that: described lower base is all satisfactory monolayer lower base of lucifuge and compatible pharmaceutical performance.
Optimal technical scheme is again, and the needle for inserting bottle of described dropper and transfusion device, air filter are one-body molded is dropping funnel lid.
The present invention, owing to adopting technique scheme, achieves goal of the invention easily.
