Abstract

An exhaust-free dropping funnel adopted by an infusion device belonging to the field of medical equipment. The dropping funnel can not only simplify exhaust operation and abate labor intensity, but also avoid air bubbles in a pipeline during exhaust or infusion. The dropping funnel adopts the technical scheme as follows: the designed exhaust-free dropping funnel adopted by the infusion device comprises a funnel drum, a funnel cover and a funnel core, wherein the funnel core is connected with a liquid outlet at the bottom of the funnel drum; the funnel core consists of a core body and a core cover; the core cover is sheathed outside the core body; the upper end of the core cover is sealed and hollow, and at least one slot-shaped or hole-shaped liquid inlet is arranged the side surface of the core cover; and the upper end of the core body is sealed and hollow, and at least one slot-shaped or hole-shaped liquid inlet is arranged on the side surface of the core body. When the infusion device provided with the exhaust-free dropping funnel is in use, the dropping funnel does not need to be inverted or pinched; and when a liquid level reaches the top of the core cover, liquid enters an infusion pipeline through a slit, and air in the funnel core and the infusion pipeline is automatically discharged out, thereby achieving the effects of avoiding pinching the dropping funnel and automatically exhausting.

Description

A kind of infusion set is with exempting from the aerofluxus dropping funnel

One, technical field

This utility model belongs to medical instruments field, specially refers to a kind of infusion set with exempting from the aerofluxus dropping funnel.

Two, background technology

General infusion set product (comprising precision infusion set and non-precision infusion set) following problem of ubiquity in nursing procedure commonly used clinically at present:

1, bleeding is loaded down with trivial details, and clinical bleeding commonly used comprises following six steps:

(1)---(2) are inverted dropping funnel, and------(4) reset, and (6) close actuator to (3) extruding dropping funnel in aerofluxus---(5) wait aerofluxus is finished---to insert bottle

Bleeding is loaded down with trivial details, and the operating time is longer, increases nursing labor intensity; And clinical because bleeding is lack of standardization causes transfusion device aerofluxus failure that generation is often arranged, and causes transfusion device and liquid waste.

2, bleeding process need extruding dropping funnel, for the little nursing staff of strength, operation is inconvenience very; Winter temperature is low easily to cause the dropping funnel hardening, increases nursing staff's labor intensity especially greatly, and clinical nursing staff often complains that the dropping funnel of transfusion device is too hard, is not easy to operation.

There are the problems referred to above during in view of clinical use transfusion device, wish to invent a kind of easy to operate, can solve the device of transfusion device exhausting problem, further optimize the safety and the effectiveness of infusion apparatus product.

Three, summary of the invention

This utility model can be simplified bleeding, avoids the aerofluxus failure, has reduced labor intensity, and in order to achieve this end, the technical scheme that is adopted is:

This utility model has designed a kind of infusion set with exempting from the aerofluxus dropping funnel, has comprised bucket tube, bucket cover and bucket core, and the bucket core is connected with bucket tube bottom liquid outlet; The bucket core is made up of core body and core cap, and core cap is enclosed within the outside of core body, and the gap between core body and the core cap is 0.5～4mm; End closure on the core cap, hollow, the side has at least one groove shape or inlet that at least one is poroid, and groove width or bore dia are 0.3～5mm; End closure on the core body, side also have at least one groove shape or inlet that at least one is poroid, and groove width or bore dia are 0.3～3mm, hollow, and core body lower end liquid outlet links to each other with a bucket tube liquid outlet.

Compare with infusion apparatus product commonly used clinically, the beneficial effects of the utility model are: increased in the general infusion set dropping funnel and exempted from aerofluxus bucket core, during clinical transfusion, behind transfusion device needle for inserting bottle insertion bottle stopper, medicinal liquid enters in the dropping funnel under action of gravity automatically, and liquid level rises in the dropping funnel.Because the liquid body surface tension effects has only when liquid level rises to certain altitude in the dropping funnel, liquid just can enter between core body and the core cap, and the liquid level rate of climb between core body and the core cap is less than the dropping funnel liquid level rate of climb; Behind liquid level submergence bucket core in the dropping funnel, because air can't be discharged in the dropping funnel, cause the dropping funnel internal pressure to increase, acceleration liquid enters the space between core cap and the core body, the air of inside, space is subjected to the extruding of liquid and can discharges by the inlet of core body, and liquid can not be discharged under capillary effect; Rising along with liquid level between core body and the core cap, the core body inlet is submerged, the pressure that produces when dropping funnel is inner is during greater than core surface tension force, liquid can flow into the infusion pipeline by the inlet of core body, exempt to be inverted and exempt to pinch the operation of dropping funnel and directly discharge the effect of air in the dropping funnel thereby reach, simplified bleeding, reduced labor intensity, can also effectively prevent the generation of gas-liquid mixed and aerofluxus failure, make transfusion safer.

Four, description of drawings

Fig. 1 is this utility model structural representation;

Fig. 2 is bucket cored structure sketch map;

Five, the specific embodiment

With reference to Fig. 1,1 bucket tube, 2 bucket covers, 3 bucket cores;

With reference to Fig. 2,31 core bodys, 32 core caps;

With reference to Fig. 1, bucket tube 1, bucket cover 2, core body 31, core cap 32 all adopt macromolecular material injection molded, at first core body 31 and core cap 32 are connected to form bucket core 3, the core 3 that will struggle against again is connected with bucket tube 1 bottom liquid outlet, bucket cover 2 is assembled with bucket tube 1 to become to exempt from the aerofluxus dropping funnel at last.To exempt from the aerofluxus dropping funnel replaces common dropping funnel to be assemblied in being on the transfusion device exempting from exhaust transfusion device.

When using configuration to exempt from the transfusion device of aerofluxus dropping funnel, bottle plug puncture unit is inserted in the medicine bottle, open flow regulator, need not be inverted dropping funnel and pinch dropping funnel, medicinal liquid can flow to dropping funnel automatically under the self gravitation effect, liquid level slowly raises and submergence bucket core top in the dropping funnel, air can be discharged by core cap and core body upper liquid outlet in the dropping funnel, exempts to be inverted and to exempt to pinch dropping funnel, self-bleeding effect thereby reach.

Claims

1. an infusion set is characterized in that having comprised bucket tube (1), bucket cover (2) and bucket core (3) with exempting from the aerofluxus dropping funnel, and the bucket core is connected with bucket tube bottom liquid outlet.

2. the aerofluxus dropping funnel of exempting from according to claim 1, the core (1) that it is characterized in that struggling against is made up of core body and core cap, core cap is enclosed within the outside of core body, gap between core body and the core cap is an end closure on 0.5～4mm core cap, hollow, the side has at least one groove shape or inlet that at least one is poroid, and groove width or bore dia are 0.3～5mm; End closure on the core body, side also have at least one groove shape or inlet that at least one is poroid, and groove width or bore dia are 0.3～3mm, hollow, and core body lower end liquid outlet links to each other with a bucket tube liquid outlet.
