Abstract
A kind of automatic vent stops liquid formula transfusion device automatic vent and stops liquid device, comprises air-filtering membrane, only liquid film, only liquid device upper cover and stops liquid device lower cover.It is characterized in that air-filtering membrane plays dropping funnel and the bubble discharge effect stopped in liquid device.The effect of auto-stopping liquid film main start-stop liquid, when medicinal liquid will be totally lost, under the effect stopping the tension force on liquid film, makes liquid stop flowing out, in like manner, makes gas also stop row going down.Only liquid film encloses liquid outlet, by formation one section of fluid-tight pipeline from liquid outlet to pipeline terminal, prevents air from entering human body, can effectively prevent from infusing terminate after the blood back that causes.This utility model production is easy to assembly, and manufacturing process is simple, and production cost is low.
Description
Technical field
This utility model relates to a kind of automatic vent and stops liquid device, particularly relates to the automatic vent that a kind of automatic vent stops on liquid formula transfusion device and stops liquid device, belong to technical field of medical instruments.
Technical background
Current disposable infusion set does not have the function of automatic liquid-stopping, transfusion device is when transfusion just starts, medicinal liquid enters dropping funnel by tube for transfusion, gas in dropping funnel is easily discharged formation gas-liquid mixture downwards and is entered in the tube for transfusion of dropping funnel bottom by liquid, therefore bubble is produced, simultaneously, because of the surface tension effects of tube for transfusion inwall, the inwall of tube for transfusion easily adsorbs a small amount of bubble, the healthy of patient is threatened, so medical personnel are when infusing, infuse again after the bubble in transfusion catheter must being discharged completely.So medical personnel can after inserting infusion bottle by bottle plug puncture unit when infusing beginning, dropping funnel is inverted, after making a certain amount of liquid be full of dropping funnel, along putting dropping funnel, do the generation preventing bubble like this, the process getting rid of bubble in this is comparatively difficult, time-consuming and loaded down with trivial details, can not thoroughly be drained by bubble again.Due to aerofluxus not thoroughly, change the liquid reason such as not in time, cause below dropper and enter inequality air, if can not dissolve in blood in time after these air enter human body, blood vessel embolism phenomenon may be caused in blood flow process, even flow into heart along blood, when these gases occupy ventricle, the circulation of blood will be hindered, time serious, likely cause the death of patient.
In patient's infuse medical fluid process, be totally lost as medicinal liquid and do not extract infusion needle, the adverse consequences of blood backflow will occur, blood back may form blood coagulation, easily form microthrombus when small blood clot pours blood vessel during transfusion again, even may occur the extreme situation endangering patient vitals.When infusing again after blood back, need further aerofluxus, sometimes also there will be syringe needle blocking, again as improper in aerofluxus during transfusion, can air embolus be formed, in input body, serious air embolism may be caused, easily cause medical tangle and patient and family members to the complaint of nursing staff and hospital and discontented.Blood back brings fear to patient and family members, and family members and patient, because of the anxiety of height, can not get good rest, and nurse will increase the tour frequency, adds workload and causes the anxiety of work with flurried.
Summary of the invention
This utility model technical issues that need to address are to provide one automatically can discharge bubble, and meanwhile, medicinal liquid is totally lost and is stopped liquid, avoid the automatic liquid-stopping device that air enters the adverse consequences of human body and blood backflow occurs.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of automatic vent stops liquid formula transfusion device automatic vent and stops liquid device, comprise only liquid device upper cover (15) and only liquid device lower cover (16), only liquid device is covered with air-filtering membrane (14), under be covered with only liquid film (17), it is characterized in that: only liquid device upper cover (15), lower cover (16) adopts medical macromolecular materials ABS or other medical macromolecular materials to manufacture, only liquid device upper cover (15) is provided with inlet and steam vent, only liquid device lower cover (16) is provided with liquid outlet and welds only liquid film (17).
This utility model structure is simple, and manufacturing process is simple, and production cost is low.This transfusion device automatic vent is particularly adopted to stop liquid device, the automatic vent when infusing, can automatic liquid-stopping after transfusion terminates, use simple, make transfusion safer.Only liquid film can adopt the secondary filter film of less than 5 μm and 5 μm, and this new structure is accurate filter.
Below in conjunction with drawings and Examples, this utility model product is further described.
Accompanying drawing explanation
Fig. 1 is the structure sectional view that transfusion device automatic vent stops liquid device.
Fig. 2 is the structural representation that automatic vent stops liquid transfusion device.
Detailed description of the invention
As shown in Figure 1, automatic vent stops liquid device assembly and is: (14) air-filtering membrane, and (15) are liquid device upper cover only, and (16) are liquid device lower cover only, and (17) are liquid film only.
Below in conjunction with example and contrast accompanying drawing and embodiment, liquid transfusion device is stopped to automatic vent of the present invention and further illustrates.As Fig. 1 this utility model automatic vent stops, liquid transfusion device stops liquid device (9) by bottle plug puncture unit assembly (1), air inlet pipe (2), air filter (3), flow regulator (4), feed tube (5), three-way connector (6), dropper (7), dropper component (8), automatic vent, flow regulator (10), long tube (11), spiral two-way (12), venoclysis needle (13) form.Automatic vent stops liquid device and comprises automatic exhaust device and automatic liquid-stopping device: the only liquid device upper cover (15) that automatic exhaust device is located at infusion unit titrimeter (8) below is equipped with the automatic exhaust device that air-filtering membrane (14) forms with steam vent, air-filtering membrane sweat soldering or ultrasonic bonding; Stopping in liquid device lower cover (16) the automatic liquid-stopping device being welded with only liquid film (17) and being formed, stop liquid film sweat soldering or ultrasonic bonding.When transfusion uses, open flow regulator (4) and flow regulator (9), take off bottle plug puncture unit sheath, bottle plug puncture unit is inserted in medicine bottle, medicinal liquid is along with in dropper (7) inflow dropper component (8), because only liquid device upper cover (15) inside is provided with automatic exhausting equipment, bubble to be discharged only liquid device (9) outward and under making liquid stream by air-filtering membrane (14) by liquid when only liquid device (9), thus prevents bubble from entering human body.At the end of transfusion, liquid level drops to only liquid film (17) position, and only stopping is flowed by liquid device lower cover (16) lower end liquid, prevents air from entering human body or occurs blood backflow phenomenon.
Claims (1)
1. an automatic vent stops liquid formula transfusion device automatic vent and stops liquid device, comprise only liquid device upper cover (15) and only liquid device lower cover (16), only liquid device is covered with air-filtering membrane (14), under be covered with only liquid film (17), it is characterized in that: only liquid device upper cover (15), lower cover (16) adopt medical macromolecular materials ABS or other medical macromolecular materials to manufacture, only liquid device upper cover (15) is provided with inlet and steam vent, and only liquid device lower cover (16) is provided with liquid outlet and welds only liquid film (17).
