Abstract
The utility model belongs to the medical equipment, and discloses a liquid dripping speed regulator. A piston cavity is formed in an air cylinder, an air inlet communicated with the piston cavity is formed in the upper end of the air cylinder, an air outlet joint communicated with the piston cavity is formed in the lower end, and a rubber seal and a rubber plug which can be sealed and matched with the air outlet joint are arranged on the air outlet joint; the lower end of the rubber plug is connected with an air feeding pipe, a control valve is arranged on the air feeding pipe, and a needle connected with an infusion bottle is arranged at the tail end of the air feeding pipe; and a rodless piston is arranged in the piston cavity, and a counterweight part is arranged above the rodless piston. The liquid dripping speed regulator is simple in structure and convenient to operate, air pressure is adopted to control the liquid dripping speed, too slow dripping caused by thick medical liquid or pipe blockage is avoided; and meanwhile, the air cylinder is pre-filled with air, pure air after treatment can be adopted, and the medical liquid can be further prevented from being polluted by germs in the air.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of liquid dropping speed adjuster.
Background technology
Liquid dropping speed adjuster is mainly used for regulating a speed in the time of clinical transfusion, current liquid dropping speed adjuster is mostly for gravity infusion process, it is only the object that plays regulating transfusion speed by the cross-sectional sizes of control infusion pipeline, can not provide certain pressure to the medicinal liquid in medicine bottle, affected by the caliber restriction of tube for transfusion and the viscosity of medicinal liquid, current liquid dropping speed adjuster does not often have accurate speed governing object, and then brings some inconvenience to clinical treatment.In addition, at present, in infusion process, the air in ward often contains certain pathogenic bacteria, with medicinal liquid directly contacts after entering bottle by air inlet pipe, and pathogenic bacteria easily, with in medicinal liquid input blood of human body, exists certain potential safety hazard.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that this utility model provides, and safety and sanitation regulate that to drip speed convenient, is particularly useful for the not liquid dropping speed adjuster of clinical case such as freely of medicinal liquid that viscosity is high or infusion pipeline circulation.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of liquid dropping speed adjuster, comprise an air collector, and in air collector, be plunger shaft, air collector upper end is provided with the air inlet communicating with plunger shaft, and lower end is provided with the air outlet adapter communicating with plunger shaft; On air outlet adapter, establish rubber stopper and the rubber plug that can be sealed and matched with it; The lower end of described rubber plug is connected with snorkel, and snorkel is provided with control valve, and the tail end of snorkel is provided with the syringe needle for being connected with infusion bottle; In described plunger shaft, be provided with a rodless piston, the top of rodless piston is provided with counterweight.
Described air inlet can hold counterweight, to change the counterweight of Different Weight.
The utlity model has following beneficial effect: when transfusion, this utility model is connected with infusion bottle by syringe needle, air in plunger shaft enters in infusion bottle under the pressure-acting of rodless piston, make infusion bottle bottom form certain malleation, and then order about medicinal liquid and enter tube for transfusion, control to the air feed speed in infusion bottle by control valve, can play to regulate and drip a fast object; In the time that control valve cuts out, negative pressure will be formed on infusion bottle bottom, and then can stopping infusion; When medicinal liquid is when comparatively a little obstructions occurs for thickness or pipeline, can tune up control valve, guarantee to there is enough malleations in infusion bottle, ensure the Reasonable Speed of infusing.This utility model is simple in structure, easy to operate, adopts air pressure to control liquid droping speed, has avoided the generation of dripping speed and crossing slow situation causing because of medicinal liquid thickness or pipeline blockage; Meanwhile, because it is contained in air in air collector in advance, can adopt the pure air of processing, and then avoid airborne pathogenic bacteria to pollute medicinal liquid.

Fig. 1 is this utility model structural representation.
In figure, 1, rubber plug, 2, snorkel, 3, syringe needle, 4, air inlet, 5, counterweight, 6, rodless piston, 7, plunger shaft, 8, air collector, 9, rubber stopper, 10, air outlet adapter, 11, control valve.
Detailed description of the invention
Shown in Fig. 1, a kind of liquid dropping speed adjuster, comprise an air collector 8, in air collector 8, it is plunger shaft 7, air collector 8 upper ends are provided with the air inlet 4 communicating with plunger shaft 7, lower end is provided with the air outlet adapter 10 communicating with plunger shaft 7, establishes rubber stopper 9 and the rubber plug 1 that can be sealed and matched with it on air outlet adapter 10; The lower end of described rubber plug 1 is connected with snorkel 2, and snorkel 2 is provided with control valve 11, and the tail end of snorkel 2 is provided with the syringe needle 3 for being connected with infusion bottle; In described plunger shaft 7, be provided with a rodless piston 6, the top of rodless piston 6 is provided with counterweight 5.When transfusion, air collector 8 is connected with infusion bottle by snorkel 2, air in plunger shaft 7 enters in infusion bottle under the pressure-acting of rodless piston 6, make to be in infusion bottle malleation, and then order about medicinal liquid and enter in tube for transfusion, control air input speed by control valve 11, can play to regulate and drip fast object.
