Description
Technical field
This utility model relates to a kind of precision infusion set, is specifically related to a kind of precision infusion set that can automatic vent stops liquid.
Background technology
The transfusion device using clinically is at present plain edition gravity transfusion system, must apply external force dropping funnel and just can descend liquid during use, increases nurse's workload.During transfusion, family numbers of patients or patient need to observe transfusion situation, need to change in time medicine bottle when medicine bottle inner liquid medicine drips off, otherwise will there is air to enter in the flexible pipe of dropping funnel below, make to produce bubble in flexible pipe, if bubble enters human body with medicinal liquid, can damage patient's health; Discharge bubble, operation is trouble very, to medical personnel, strengthens workload.General employing is at present closed flow regulator and is prevented that air from entering human body, but can cause blood back like this, also unfavorable to patient.
The liquid medicine filter of the general infusion set of current clinical use, adopt fiber speed filter membrane, can not carry out the classification of accurate aperture, use and surpass a certain amount of or chance soda acid, easily there is fibre shedding, and microgranule more than particle diameter 15 μ m in main filtering medicinal liquid, lower to the rejection rate of the following microgranule of 15 μ m, therefore, existing transfusion device can not meet at when transfusion automatic vent and the functional requirement of automatic liquid-stopping.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of precision infusion set that can automatic vent stops liquid, can automatic vent and automatic liquid-stopping while guaranteeing to infuse, and meets user demand.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is as follows:
A kind of automatic vent stops liquid precision infusion set, comprise bottle plug puncture unit, the air inlet with filter and stopper, dropper, dropping funnel, flexible pipe, flow regulator and venoclysis needle, in described dropping funnel, be provided with can automatic liquid-stopping liquid medicine filtering membrane, on the flexible pipe that is communicated with dropping funnel and venoclysis needle, be provided with precision liquid medicine filter.
Described precision liquid medicine filter comprises upper cover and the base being used in conjunction with each other, and is provided with double medium filtration medium on base, is provided with perforation on base.Described filter medium is poly (ether sulfone) film.
On bottle plug puncture unit, be movably equipped with protective sleeve for bottle stopper puncture outfit.
Described automatic vent stops liquid precision infusion set, also comprises the liquid injecting piece for dosing, and described liquid injecting piece is between dropping funnel and precision liquid medicine filter.
Described liquid injecting piece is 6:100 joint.
Described liquid medicine filtering membrane is poly (ether sulfone) film.
This utility model automatic vent stops liquid precision infusion set, is provided with one deck poly (ether sulfone) film in dropping funnel, and the fiber while having liquid in dropping funnel on film is erect, and after medicinal liquid is totally lost, the automatic sagging covering of fiber is considered hole in closed state, plays automatic liquid-stopping effect.In accurate filter, adopt double-deck poly (ether sulfone) film, water environment capacity is strong, filter opening rule, even, filtering accuracy height can not produce foreign body and come off, little to drug adsorption, there is to strict classification in aperture, can need to select suitable aperture (5 μ m, 3 μ m, 2 μ m) according to clinical.Only transfusion device need be inserted after medicinal liquid bottle, transfusion device can be by the steam vent of the automatic exhaust device in accurate filter, automatic air-out.
Beneficial effect: compared with prior art, advantage of the present utility model comprises: being provided with one deck poly (ether sulfone) film in dropping funnel can its effect to automatic liquid-stopping.It is double-deck poly (ether sulfone) film that accurate filter is selected, by the steam vent of the automatic exhaust device in accurate filter, and automatic air-out, do not need repetitive manual aerofluxus, exhaust velocity is fast, can eliminate the bubble in liquid and guarantee no leakage, compared with market like product aerofluxus fast approximately 30% to 40%.
Accompanying drawing explanation
Fig. 1 is the structural representation that automatic vent stops liquid precision infusion set;
Fig. 2 is the structural representation of accurate filter upper cover;
Fig. 3 is the structural representation of accurate filter base.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1; automatic vent stops liquid precision infusion set, and main structural components comprises protective sleeve for bottle stopper puncture outfit 1, bottle plug puncture unit 2, the air inlet 3 with filter and stopper, dropper 4, dropping funnel 5, liquid medicine filtering membrane 6, flexible pipe 7, flow regulator 8, liquid injecting piece 9, precision liquid medicine filter 10 and venoclysis needle 11 etc.Protective sleeve for bottle stopper puncture outfit 1 is actively installed on bottle plug puncture unit 2, for the protection of bottle plug puncture unit 2; Bottle plug puncture unit 2 is connected with the air inlet 3 with filter and stopper, air inlet 3 is connected with one end of dropping funnel 5 by one section of flexible pipe 7, dropper 4 is located at flexible pipe 7 one end in dropping funnel 5, liquid medicine filtering membrane 6 is located at the interior one end away from dropper 4 of dropping funnel 5 near bottom position, the other end of dropping funnel 5 communicates with liquid injecting piece 9, precision liquid medicine filter 10 and venoclysis needle 11 successively by another section of flexible pipe 7, on the flexible pipe 7 between dropping funnel 5 and liquid injecting piece 9, establishes actuator 8.Wherein, liquid medicine filtering membrane 6 is poly (ether sulfone) film.Liquid injecting piece 9 is 6:100 joint.
