Abstract
A sandwich-type transfusion device self-stop controller is composed of three layers of materials. Outer edges of the three layers of the materials are connected in a sealing mode, a small hole is arranged in the middle layer of the materials and communicated with space in two sides of the middle layer, a transfusion channel of the small hole in the middle layer is opened or closed through the three layers of the materials according to pressure, and functions that normal transfusion is carried out when medical liquid is sufficient and the transfusion is stopped automatically when the medicine liquid runs out are achieved. The self-stop controller has the advantages of preventing air from entering and blood from returning, guaranteeing medical safety, relieving pain of patients, avoiding unnecessary medical disputes, controlling transfusion of the medical liquid manually, avoiding waste, guaranteeing medical effects, and being simple in structure, low in cost and convenient to produce industrially.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of transfusion device from stop controller, can transfusion can automatic stopping infusion in the time of will using up transfusion device from stop controller.
Background technology
Transfusion device relies on action of gravity that medicinal liquid is inputted 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 large 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 slightly have carelessness, when will using up, medicinal liquid fails in time to stop infusing, and medicinal liquid all is totally lost rear air followed by entering patient's blood vessel, have influence on patient's life security when serious, and when changing medicine bottle, if need the medical worker again to patient's piercing needle, also bring misery to the patient.3, patient and care-giver neglect always unavoidably because energy expends excessively, contingency occurs easilier, increase unnecessary injury 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 device from stop controller, will fail when most at medicinal liquid, and automatically stop to continue transfusion, and in transfusion device, keep the medicinal liquid of some and certain altitude position, both can prevent that air from entering vein, also can prevent return blood.
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.Be comprised of trilaminate material from stop controller, the outward flange of trilaminate material is tightly connected, and middle layer material is established an aperture, is communicated with the space of both sides, middle level, it is characterized in that trilaminate material opens or seal the infusion channel of middle level aperture 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 larger, bulge from the outer two layers material pressurized of stop controller, medicinal liquid passes through by the through-core hole in middle level, normal infusion.
Along with defeated under the medicinal liquid, liquid level descends, and hydraulic pressure reduces gradually, and the degree that bulges from the outer two layers material of stop controller reduces gradually.
When the medicine bottle inner liquid medicine will be use up, cladding material was until recover normal form, the through-core hole in sealing middle level.
Because it is lower defeated that the medicinal liquid below stop controller continues because of gravity, thereby form negative pressure.Under atmospheric effect, cladding material and middle layer material being pressed together tightly, through-core hole is firmly sealed, and transfusion stops fully.
The beneficial effects of the utility model are: will fail when most at medicinal liquid, and automatic stopping infusion, and in transfusion device, keep the medicinal liquid of some and certain altitude position.Concrete advantage is: 1, alleviate care-giver's working strength and workload; 2, prevent into air and blood back, guarantee of the 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.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is that Emhorn sandwich type automatic stop infusion apparatus is from the stop controller front elevation.
Fig. 2 is that Emhorn sandwich type automatic stop infusion apparatus is from the stop controller side view.
Fig. 3 is the A-A profile.
Fig. 4 is the B-B profile.
Among Fig. 3,1, the feed liquor layer, 2, sandwich of layers, 3, go out liquid layer, 4, inlet, 5, liquid outlet, 6, through-core hole.
The specific embodiment
Be installed on the pipeline of transfusion device by bonding way from stop controller.
In Fig. 3, process through-core hole by punching technology, then by bonding or welding procedure with trilaminate material firmly together.
