Abstract
The utility model relates to an improvement of a medical infusion device, in particular to an infusion device with automatic flow-stopping function, which is safe and simple in structure. The infusiondevice comprises an upper needle head, an infusion pipe, an air storage chamber, an adjustor and a lower needle head; and is structurally characterized in that a liquid storage chamber is arranged between the upper needle head and the air storage chamber, a floating ball is arranged inside the liquid storage chamber, and a funnel is arranged at the bottom of the liquid storage chamber.
Description
Technical field
This utility model relates to a kind of improvement of medical Transfusion device structure.
Background technology
At present, the patient need be careful the surplus of tube for transfusion herb liquid constantly when transfusion, because the transfusion persistent period is longer, the nurse personnel have carelessness slightly, will cause malpracticees such as blood backflow or air admission blood vessel, the life security that seriously jeopardizes the patient.
The utility model content
This utility model just provides a kind of automatic stopping flow syringe safe, simple in structure.
This utility model adopts following technical scheme: this utility model comprises syringe needle, transfusion catheter, air storage chamber, actuator, following syringe needle, its structural feature is to go up between syringe needle and the air storage chamber to be provided with liquid storage cylinder, be provided with ball float in the liquid storage cylinder, the liquid storage cylinder bottom is provided with funnel.
This utility model beneficial effect:
This utility model is simple in structure, with low cost, be beneficial to and popularize.
1, safety, reliable:
Owing to be provided with liquid storage cylinder between syringe needle and the air storage chamber on this utility model, be provided with ball float in the liquid storage cylinder, the liquid storage cylinder bottom is provided with funnel; When medicinal liquid is about to be totally lost, ball float descends with liquid level and since ball float proportion be 0.9,90% volume below liquid level, ball float arrives funnel bottom prior to liquid level and blocks; Thereby avoid causing malpracticees such as blood backflow or air admission blood vessel;
2, simple in structure, utilization popularizes:
This utility model has added on the structure of original transfusion device and had the liquid storage cylinder that leaks head, ball float, and is simple in structure, cost is lower, be beneficial on a large scale and popularize.
Description of drawings
Accompanying drawing is this utility model structural representation.
The specific embodiment
This utility model comprises syringe needle 1, transfusion catheter 2, air storage chamber 3, actuator 4, following syringe needle 5, is provided with liquid storage cylinder 6 between last syringe needle 1 and the air storage chamber 3, is provided with ball float 7 in the liquid storage cylinder 6, and liquid storage cylinder 6 bottoms are provided with funnel 8.
Below in conjunction with structure, course of action of this utility model is described:
During transfusion state, ball float 7 floats on the liquid level, the medicinal liquid proper flow;
When medicinal liquid is about to be totally lost, ball float 7 descends with liquid level, because ball float 7 proportions are lighter, 90% volume is below liquid level, and ball float 7 arrives funnel 8 bottoms prior to liquid level and blocks; The liquid level of following air storage chamber 3 descends under action of gravity to some extent, but immediately produces negative pressure, makes the ball float 7 in the liquid storage cylinder 6 tightly block funnel 8 bottoms, thereby makes medicinal liquid stop to flow.
After waiting to change new medicine bottle, new medicinal liquid enters transfusion catheter 2, as long as the air storage chamber 3 below the extruding makes air pressure back down ball float 7, ball float 7 floats on again on the liquid level, and medicinal liquid again can proper flow.
This utility model funnel 8 can be gum elastic.
