Abstract
The utility model relates to a venous rapid transfusion pressurizer, which belongs to the technical field of medical devices, and comprises a puncture needle (1), an air filter (2) and an elastic airbag (3). The utility model is characterized in that one end of the elastic airbag (3) is equipped with a unidirectional inlet valve (4), the other end is equipped with a unidirectional exhaust valve (5), one end of the air filter (2) is communicated with the unidirectional exhaust valve (5), and the other end is connected with the puncture needle (1). The utility model has the advantages of simple structure and convenient operation, a bottle stopper does not need to be punctured again and again, liquid is not capable of being polluted by the air which is filtered, a needlepoint is a solid puncture needle, thereby not cutting the bottle stopper, and avoiding the dross of the bottle stopper entering into liquid medicine.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of vein prelum of infusing fast.
Background technology
In curative activity, to intracranial hypertension, lose blood, fluid loss characteristics shock and some urgency, danger, heavy patient's rescue, often to the liquid in the infusion bottle be pressurizeed rapidly in a large number from vein liquid make-up and administration.Clinically at present adopt behind the syringe pump air repeated localised puncture bottle stopper to inject air in bottle to pressurize, this method complicated operation bothers more, and the repeated localised puncture bottle stopper very easily causes the bottle stopper seepage; The air that injects filtered simultaneously makes bottle interior liquid be polluted easily, does not meet hygienic requirements.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned foot, provides a kind of simple in structure, easy to operate, both need not puncture to bottle stopper repeatedly, also can be to the vein that liquid the pollutes prelum of infusing fast.
The purpose of this utility model is achieved in that this vein prelum of infusing fast is made up of piercing needle, air filter, elastic bag, and elastic bag one end is provided with breather cheek valve, and the other end is provided with one-way exhaust valve; Air filter one end is connected with one-way exhaust valve, and the other end links to each other with piercing needle.The piercing needle needle point is solid, has the side opening that communicates with the piercing needle inner chamber below the solid needle point.
During use, the nurse inserts piercing needle in the infusion bottle, according to required transfusion speed, gently pushes elastic bag with have gentle hands, and air enters into liquid bottles by the filtration of air filter, and the liquid bottles internal pressure increases, and transfusion speed is accelerated.
Advantage of the present utility model: simple in structure, easy to operate, need not puncture to bottle stopper repeatedly, the air after the filtration can not pollute liquid, and needle point is that solid piercing needle can not cause the cutting to bottle stopper, avoids crumb of bottle stopper to enter in the medicinal liquid.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this vein prelum of infusing fast is made up of piercing needle 1, air filter 2, elastic bag 3, and elastic bag 3 one ends are provided with breather cheek valve 4, and the other end is provided with one-way exhaust valve 5; Air filter 2 one ends are connected with one-way exhaust valve 5, and the other end links to each other with piercing needle 1.Piercing needle 1 needle point is solid, has the side opening 6 that communicates with piercing needle 1 inner chamber below the solid needle point.
Claims (2)
1, a kind of vein prelum of infusing fast is made up of piercing needle (1), air filter (2), elastic bag (3), it is characterized in that elastic bag (3) one ends are provided with breather cheek valve (4), and the other end is provided with one-way exhaust valve (5); Air filter (2) one ends are connected with one-way exhaust valve (5), and the other end links to each other with piercing needle (1).
2, the vein according to claim 1 prelum of infusing fast is characterized in that piercing needle (1) needle point is solid, has the side opening (6) that communicates with piercing needle (1) inner chamber below the solid needle point.
