Abstract

Provided is an infusion automatic stopping device. The infusion automatic stopping device is formed by arranging a horizontal pipe between two layers of materials, and the periphery of the infusion automatic stopping device is sealed except for an inlet and an outlet. The infusion automatic stopping device is characterized in that an infusion channel is opened or closed according to pressure through the two layers of materials. When medicine liquid is sufficient, infusion is carried out normally, and when the medicine liquid is infused totally, the infusion can be stopped automatically. The infusion automatic stopping device has the advantages that the work strength and the workload of nursing personnel can be reduced, entering of air and returning of blood can be prevented, medical safety can be guaranteed, pains of patients can be alleviated, unnecessary medical dispute can be avoided, the medicine liquid can be controlled manually and infused totally, waste can be avoided, medical effect can be guaranteed, the structure is simple, the cost is low, and industrial production of the infusion automatic stopping device is convenient.

Description

The transfusion self-stop device

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of transfusion from stop controller, can be in the transfusion transfusion that can stop automatically infusing in the time of will using up from stop controller.

Background technology

Transfusion device relies on action of gravity that medicinal liquid is imported human vein from medicine bottle, will fail when most at medicinal liquid, can not stop to continue transfusion.For avoiding occurring contingency, the way in the reality is to rely on manual observation, approaches when being totally lost at medicinal liquid, and medical personnel or nursing staff are in time artificial to stop transfusion.In this case, bring problems: 1, manual observation medicinal liquid position and control transfusion, will expend too big energy, increase too much work and work, needs of patients is infused and many bottles when infusing for a long time, and patient and care-giver have a hard time for this reason; If 2 have carelessness slightly, when will using up, medicinal liquid fails in time to stop infusing, and medicinal liquid all is totally lost the back air followed by entering patient's blood vessel, have influence on patient's life security when serious, and when changing medicine bottle, the medical worker gives patient's piercing needle again if desired, also brings misery to the patient.3, patient and care-giver neglect always unavoidably because energy expends excessively, contingency occurs easilier, increase unnecessary damages and misery to the patient.If 4 hospital are responsible for nursery work, unnecessary medical tangle will be increased.

Summary of the invention

For working strength and the workload that alleviates the care-giver, reduce patient's misery, avoid the generation of contingency, this utility model provides a kind of transfusion from stop controller, will fail when most at medicinal liquid, and stop automatically continuing transfusion, and in transfusion device, keep the medicinal liquid of some and certain altitude position, both the air admission vein can be prevented, also blood back can be prevented.

The technical scheme that its technical problem that solves this utility model adopts is:

Pipeline at transfusion device increases by one from stop controller, is communicated with the transfusion device sealing from stop controller.From stop controller by materials at two layers in the folder transverse tube forms, seal except importing and exporting the neighboring, it is characterized in that materials at two layers opens or seal infusion channel according to pressure.。

Under such structural design, finish the function of automatic stop from stop controller according to different pressure.

When in the medicine bottle medicinal liquid being arranged, because the hydraulic pressure of medicinal liquid is bigger, outwards bloat from the materials at two layers pressurized of stop controller, medicinal liquid passes through by the gap of two interlayers, normal infusion.

Along with defeated under the medicinal liquid, liquid level descends, and hydraulic pressure reduces gradually, and the degree that outwards bloats from the materials at two layers of stop controller reduces gradually.

When the medicine bottle inner liquid medicine will be use up, materials at two layers was until recovering normal form, with the transverse tube sealing infusion channel of centre.

Because it is defeated down that the medicinal liquid below stop controller continues because of gravity, thereby form negative pressure.Under atmospheric effect, materials at two layers and transverse tube being pressed together tightly, infusion channel is by firm sealing, and transfusion stops fully.

The beneficial effects of the utility model are: will fail when most at medicinal liquid, and stop transfusion automatically, and keep the medicinal liquid of some and certain altitude position in transfusion device.Concrete advantage is: 1, alleviate care-giver's working strength and workload; 2, prevent into air and blood back, ensure medical safety; 3, alleviate patient's misery; 4, avoid unnecessary medical tangle; 5, medicinal liquid can Artificial Control be totally lost, and avoids waste and ensures medical effect; 6, simple in structure, with low cost, be convenient to suitability for industrialized production.
