Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of medical intravenous infusion set.
Background technology
Infusion treatment is a kind of medical procedure commonly used.Tradition venous transfusion mode is with the high extension of liquid medicine bottle, makes the liquid medicine bottle position be higher than position of human body, injects human vein with liquid medicine in the potential energy official post bottle between liquid medicine bottle and human body automatically through tube for transfusion, transfusion needle.Existing common transfusion device generally is made up of tube for transfusion and transfusion needle, when using this transfusion device to give patient infusion, owing to there is not special supervising device, needs family members or nurse personnel to keep an eye on usually.In case serious consequence takes place probably in the nurse error, after promptly medicinal liquid was lost, if untimely processing, the air admission blood vessel can cause patient's life danger.In the experience of life in the past, because this former thereby malpractice that cause is rarely known by the people.
On the other hand, it is reported in the prior art that the transfusion device that has automatic control function had, but this transfusion device is owing to complex structure, use cost are big, often is difficult to penetration and promotion and uses.Therefore, with regard to present medical condition, how to design a kind of simplely, cost is low, and the modified model infusion set that safety is good replaces the nurse formula infusion model of existing traditional infusion device, the problem that those skilled in the art studied really.
Summary of the invention
This utility model provides a kind of medical automatic control alarm transfusion apparatus, its objective is to design a kind of simplely, and cost is low, and the modified model infusion set that safety is good replaces the nurse formula infusion model of existing traditional infusion device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of medical automatic control alarm transfusion apparatus, comprise puncture needle, tube for transfusion, flow regulator, dropping funnel and venoclysis needle, be provided with a floating plug in the liquid storage cylinder of dropping funnel, the bottom of floating plug cooperates the unsteady liquid-level switch of formation with the liquid storage cylinder lower part outlet; The tube for transfusion of dropping funnel top is provided with a pipe capsule, is provided with a ball float in the pipe capsule, and ball float is vertically fixedlyed connected in pipe by a tinsel or thin bar with floating plug; The pairing pipe cyst wall of ball float Lower Half face is provided with the elastic wall to convex, and a contact and an outer contact in one are established in the elastic wall outside, and interior contact is provided with outer contact gap and is connected to form the shake-up alarm switch with a warning circuit; The import of pipe capsule connects to being provided with another shunt valve between the dropping funnel import, and shunt valve is provided with control liquid folder.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described shake-up alarm switch can be provided with elastic wall to convex by single face, and establishes in one pair the form formation of contact and outer contact in this elastic wall outside and singly touch alarm switch; Also can will be symmetrical arranged at left and right directions to the elastic wall of convex and interior contact and outer contact, by the electric conductor connection, two outer contacts are connected to form symmetric double contact alarm switch with warning circuit respectively between two interior contacts.
2, in the such scheme,, warning can be removed immediately, another manual normally closed switch can be in warning circuit, be connected in series in order to make warning circuit after reaching the warning effect.Operating this switch warning stops.
3, in the such scheme, described unsteady liquid-level switch can be formed by following two kinds of work surfaces cooperation:
(1), the bottom of floating plug cooperates the unsteady liquid-level switch of formation with liquid storage cylinder lower part outlet end face with the plane.
(2), the bottom of floating plug is with sphere and liquid storage cylinder lower part outlet cambered surface or cone match, constitutes the liquid-level switch that floats.
4, in the such scheme, described warning circuit can adopt existing audible alarm circuit, optical alarm circuit or acousto-optic group alarm circuit.It is on-the-spot that this alarm signal can occur in transfusion, also can be sent to nurse's night shift room or Control Room etc. by circuit.
5, such scheme should be noted following two calculating in concrete design:
(1), can effectively utilize liquid buoyancy to carry out work, both add up to the discharge opeing weight of weight less than floating plug in order to make floating plug and ball float.Floating plug and ball float can adopt hollow-core construction or other light material for this reason.Tie up to about the gravity of floating plug and ball float and the pass between the buoyancy and to meet under the above-mentioned condition prerequisite, kick the beam or overweightly all might influence operate as normal, be preferably on the basis of calculating, verify by testing again.
(2), should have certain elasticity to the elastic wall of convex on the pipe capsule, contact and outer contact in this elasticity can guarantee to touch when ball float falls, and both are come in contact.On the other hand, when ball float rose, elastic wall can guarantee the normal elasticity recovery again.
This utility model operation principle is: first, control infusion channel by floating plug is set in dropping funnel, floating plug floats medicinal liquid and flows into human vein smoothly by dropping funnel during normal infusion, after medicinal liquid uses up, floating plug falls dropping funnel is closed, and this moment, air can't enter human vein.Second, in the pipe capsule, ball float is set, this ball float is connected to form a link gear by tinsel or thin bar and floating plug, fall to closing the dropping funnel outlet simultaneously at floating plug, ball float whereabouts roof pressure is on the elastic wall of convex, contact becomes electrical connection with outer contact by separating in making, and reports to the police thereby connect warning circuit.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1, simple in structure, the low cost of manufacture of this utility model helps penetration and promotion and uses.
2, this utility model is safe and reliable, and is easy to use, not only saved nurse personnel's time and efforts, and the malpractice that can effectively avoid infusion process and taken place.
