Abstract
The invention relates to a deposable transfusion device with magnetic cut-off spherical zone. Aspirating needles, upper transfusion tubes, mid liquor chamber covers, mid liquor chambers, inferior transfusion tubes, adjustable valves, patch plugs, inferior transfusion needle tubes and transfusion needles are connected orderly into a gravity transfusion pathway. The inferior part of the mid liquor chamber is made into a cone and the inferior part of the outside is provided with a little magnetic ring. Besides, a magnetic cut-off spherical zone is provided in the mid liquor chamber. During the last phase of the transfusion, when no liquor is instilled into mid liquor chamber from the transfusion bottle, and the liquor level declines continuously, the magnetic cut-off spherical zone is dropped into the inferior cone of the mid liquor chamber by the gravity and the magnetic force, which combined with the cone forms into two upper and lower sealing rings successively which play a role in double sealing partition and keeping the status of sealing, and thereby suspend the process of transfusion automatically in order to save time for the patient and the nurse to deal with.
Description
This utility model relates to a kind of in infusion process, when the transfusion face height of intermediate liquid chamber is lower than specified altitude, can end the disposable infusion device of infusion process.
Affiliated technical field:
At present, known medical disposable transfusion device is by getting liquid syringe needle, upper tubing, center liquid chamber, descending tube for transfusion, control valve, adaptor, time Transfusion needle pipe, infusion needle to connect and constitute, and all have intake channel in the bottom of infusion bottle and the top of center liquid chamber, to keep atmospheric pressure, and the infusion bottle that hangs and get liquid syringe needle, upper tubing and center liquid chamber and all be higher than by the position of transfusion patient, the pressure that liquid-column height produces in the transfusion device just can be transfused in patient's the body under action of gravity by transfusion easily greater than being pressed by the body of transfusion patient.
Background technology:
But can stand up and alter one's posture during owing to patient infusion, during the disposable transfusion device that causes hanging is in and rocks, even in the violent sometimes swing, existing disposable transfusion device can not be under the state that aneroid can be failed automatic cut-off infusion process reliably, in the infusion process of carrying out a bottle or during final stage, the phenomenon that liquid in infusion bottle can not flow out or the liquid of infusion bottle flows to end may take place, can not there be liquid to continue to inject center liquid chamber, if this moment patient or nurse personnel can not in time notify the nurse to change infusion bottle or end transfusion, will be begun rapid decline by transfusion from the liquid level of center liquid chamber, finally the pressure that is produced by the fluid column of transfusion has been lower than patient's body pressure, thereby cause patients'blood to flow out external " blood back " phenomenon, cause influencing patient's physical and mental health along tube for transfusion.
Summary of the invention:
The technical problem that solves: can not be in the final stage deficiency of automatic cut-off reliably of infusing in order to overcome existing disposable transfusion device, this utility model provides a kind of disposable transfusion device of carrying magnetic stopping ball system, this transfusion device can not only be finished the gravity transfusion, and can be when one bottle of liquid flows to end the automatic cut-off transfusion device, thereby leave patient and nurse's processing time for.
The technical scheme that its technical problem that solves this utility model adopts is: cone is made in the following inside of center liquid chamber, and the following outside of center liquid chamber installed a magnetic rings, and places a stopping ball system in center liquid chamber.After after getting liquid syringe needle, upper tubing, intermediate liquid chamber cap, being injected center liquid chamber from the infusion bottle that hangs owing to action of gravity by transfusion, the last float that manually-operated makes stopping ball system reaches the certain height position with successively breaking away from by ball down on floating with contacting of center liquid chamber lower cone body, can be flowed into tube for transfusion down through the center liquid chamber cone by transfusion, enter in the patient body by control valve, adaptor, following Transfusion needle pipe, infusion needle again.When the liquid in the infusion bottle can not flow out, just there is not liquid to splash into center liquid chamber, thereby cause the liquid level of center liquid chamber constantly to descend, stopping ball system also drops to lower position thereupon under the effect of gravity, the magnetic field gravitation of magnet ring formation is at this moment strengthened, at the main effect of magnetic force with because the effect of letting out under the liquid and the guide effect of cone, the following of stopping ball system can successively drop to center liquid chamber lower cone body place by ball and last float, stopping ball system following by ball and last float successively at differing heights respectively at cutting with center liquid chamber lower cone bulk phase, form dual up and down border contact sealing effectiveness, and completely cut off outside atmospheric pressure, make liquid-column height can not under atmospheric pressure and action of gravity, continue to descend, after the transfusion path was intercepted, infusion process stopped automatically.Because the effect of magnetic force, when transfusion device rocked, stopping ball system can not break away from sealing station.After having only the operation of manual intervention once more to overcome magnetic attracting force, just can open sealing, infusion process just can be carried out again.
The beneficial effects of the utility model are: can be in the original functions that keeps disposable transfusion device, and the final stage of automatic cut-off transfusion prevents the generation of blood back phenomenon easily, and is simple and reliable for structure.
