Abstract
The utility model provides an automatic exhaust liquid-stopping infusion apparatus which comprises a bottle stopper puncture device assembly (1), an air inlet pipe (2), an air filter (3), a flow regulator, a tee joint connecting pipe (5), a dropper (6), a drip chamber assembly (7), a long pipe (8), a hard connector (11), a latex tube (12), a liquid medicine filter (13) and an intravenous infusion needle (14). An automatic exhaust device (15) is inserted in the drip chamber assembly (7) of the infusion apparatus, an exhaust plug (16), an air filter film (19) and an exhaust pipeline (17) are arranged above the automatic exhaust device (15), and the lower end of the dropper (6) and the upper end of the drip chamber assembly (7) are connected together in a bonding mode. The automatic exhaust liquid-stopping infusion apparatus is simple in structure, simple in manufacturing process, and low in production cost. Particularly, when the automatic exhaust liquid-stopping infusion apparatus is used, automatic exhaust can be achieved in the infusion process, liquid medicine can be made to be stopped after infusion is completed, blood is prevented from flowing back, using is simple, the working burden of medical staff can be lightened, and infusion is made to be safer.
Description
Technical field
This utility model product belongs to medical instruments field, specially refers to a kind of automatic vent and the transfusion device that stops the liquid function in patient's infusion medicinal liquid process.
Technical background
Present clinical use general infusion set, before carrying out the medicinal liquid infusion, need to be inverted dropping funnel, and the extruding dropping funnel, after making a certain amount of liquid be full of dropping funnel, along putting dropping funnel, could be by most of removal of bubbles, if misoperation, in dropping funnel, liquid and admixture of gas enter flexible pipe, form bubble.As bubble enters in patient body, easily cause the harm of aeroembolism.So, before medical personnel are infused, must be by the emptying as far as possible of the bubble in hose of infusion apparatus, the process of this artificial aerofluxus bubble is not only loaded down with trivial details but also consuming time, has increased medical personnel's work load.And, in patient's infusion medicinal liquid process, as medicinal liquid, be totally lost and do not extract infusion needle, will the adverse consequences of blood backflow occurs.Therefore, in clinical transfusion, use a kind of automatic vent to stop liquid formula transfusion device just particularly important.
Summary of the invention
This utility model is to adopt following technical proposals to realize: a kind of automatic vent stops the liquid transfusion device, comprise bottle plug puncture unit assembly (1), air inlet pipe (2), air filter (3), flow regulator, three-limb tube (5), dropper (6), dropper component (7), long tube (8), hard joint (11), latex tubing (12), liquid medicine filter (13), venoclysis needle (14), feature is that automatic exhaust device (15) is inserted in infusion unit titrimeter (7), automatic exhaust device (15) adopts medical macromolecular materials, automatic exhaust device (15) top is provided with venting plug (16), air-filtering membrane (19) and gas exhaust piping (17), the lower end of dropper (6) links together with dropper component (7) upper end by bonding, the upper end of dropper (6) with by three-limb tube (5) or directly be connected with the lower end of bottle plug puncture unit assembly (1), form the feed liquor path.Further, upper casing, lower casing are installed in dropper component (7) lower end, stop the automatic liquid-stopping device (8) that liquid film forms, long tube (10) upper end is connected with the lower end of automatic liquid-stopping device (8), form the fluid path, automatic liquid-stopping device (8) upper casing, lower casing adopt medical macromolecular materials ABS.
This utility model is to have set up the automatic exhaust device with degassing function and the automatic liquid-stopping device that stops the liquid function on the basis of common disposable infusion set.This utility model, in the clinical transfusion process, is used step the same with general infusion set, and, reduced and pushed the way that dropping funnel is manually got rid of bubble, prevent again the adverse consequences of blood backflow or aeroembolism.Greatly alleviated medical personnel's work load.
This utility model is simple in structure, and manufacturing process is simple, and production cost is low.Particularly adopt this automatic vent to stop the liquid transfusion device, can automatic vent in infusion process, can make the medicinal liquid only liquid of being totally lost, automatically infusion channel is closed, prevent blood backflow, use simply, make patient's overall process of infusing safer.
The accompanying drawing explanation
Accompanying drawing 1 stops the structural representation of liquid transfusion device for this automatic vent.
The structural representation that accompanying drawing 2 is this automatic exhaust device.
The structural representation that accompanying drawing 3 is this automatic liquid-stopping device
The specific embodiment
A kind of automatic vent stops the liquid transfusion device, comprise bottle plug puncture unit assembly 1, air inlet pipe 2, air filter 3, small size flow regulator 4, three-limb tube 5, dropper 6, dropper component 7, automatic liquid-stopping device 8, large size amount actuator 9, long tube 10, hard joint 11, latex tubing 12, liquid medicine filter 13, venoclysis needle 14, it is characterized in that: be inserted with automatic exhaust device 15 above infusion unit titrimeter assembly 7, be provided with venting plug 16 in automatic exhaust device 15 upper ends, air-filtering membrane 19 and 1 gas exhaust piping 17, and automatic exhaust device 15 lower ends are close to dropping funnel 7 inwalls and are positioned at dropping funnel 7, gas exhaust piping 17 lower ends and dropping funnel 7 upper end liquid outlets are not on same.
Claims (2)
1. an automatic vent stops the liquid transfusion device, comprise bottle plug puncture unit assembly (1), air inlet pipe (2), air filter (3), flow regulator, three-limb tube (5), dropper (6), dropper component (7), long tube (8), hard joint (11), latex tubing (12), liquid medicine filter (13), venoclysis needle (14), feature is that automatic exhaust device (15) is inserted in infusion unit titrimeter (7), automatic exhaust device (15) adopts medical macromolecular materials, automatic exhaust device (15) top is provided with venting plug (16), air-filtering membrane (19) and gas exhaust piping (17), the lower end of dropper (6) links together with dropper component (7) upper end by bonding, the upper end of dropper (6) with by three-limb tube (5) or directly be connected with the lower end of bottle plug puncture unit assembly (1), form the feed liquor path.
