It is an ideal exhaust-free infusion set.
Description
Technical field
The invention belongs to medical mechanical domain, a kind of specifically exhaust transfusion device of exempting from.
Background technology
We know that disposable infusion set is the medical apparatus and instruments of using always, comprise bottle plug puncture unit, dropping funnel, fluid flow regulator, liquid medicine filter, venoclysis needle as the one of which, by transfusion catheter they are chained together.Medicinal liquid flows into through bottle plug puncture unit, and the outlet that oozes through dropping funnel from dropper flows into catheter of transfusion system through liquid medicine filter, venoclysis needle entering human body.The transfusion initial period, owing to be empty in the conduit, medicinal liquid gets into conduit and can move down fast, because of medicinal liquid is drop by drop to get into conduit, and air is arranged in the dropping funnel, like this, medicinal liquid is interrupted in the middle of in the conduit at dropping funnel rear portion and clips air.Along with medicinal liquid increasing owing to frictional force and capillary effect in conduit, the speed of moving down of medicinal liquid slows down gradually, and begins in the dropping funnel accumulated, and the medicinal liquid of entering conduit becomes successive, no longer includes in the air admission conduit.Air in the medicinal liquid has injury as getting into human body to the people, and serious can threat to life.Therefore, medical personnel will in time drive the bubble in the medicinal liquid out of, to guarantee transfusion safety.Like this, both waste medicinal liquid, and caused drug effect to reduce, increased medical personnel's labor intensity again, wasted a large amount of working times.And present transfusion device and dropping funnel do not have and exempt from deflated function at the transfusion initial period.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; Provide a kind of rational in infrastructure; Sneak into bubble in the transfusion catheter inner liquid medicine when avoiding the transfusion beginning, save " aerofluxus bubble " operation of transfusion, alleviate medical personnel's labor intensity; Time saving and energy saving, handled easily exempt from exhaust transfusion device.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of exhaust transfusion device of exempting from; Include dropping funnel, liquid medicine filter, the venoclysis needle of bottle plug puncture unit, band dropper, by transfusion catheter they are chained together, a flow actuator is also installed in the transfusion catheter outside between dropping funnel and the liquid medicine filter; It is characterized in that: said dropping funnel middle part is provided with a drain cover; Drain cover and dropping funnel inwall interference fit are installed, and drain cover appearance is provided with the intake chute of downward conducting, are provided with a drain post in the space that drain cover and dropping funnel bottom form; The outlet of drain post and dropping funnel is adhesively fixed, and is communicated with the bottom transfusion catheter.
Drain cover according to the invention is a cap structure, and its appearance is provided with the intake chute of three conductings.
The inlet of drain post according to the invention in dropping funnel is positioned at the top of drain cover bottom cover mouth.
The present invention is owing to increase the drain cover and a drain post of a band intake chute in dropping funnel; The transfusion initial period, the air in dropping funnel and the transfusion catheter can be concentrated discharge, against existing technologies; The medicinal liquid that can not occur entrapped air in the transfusion catheter of the present invention has been saved " the aerofluxus bubble " of transfusion and has been operated.The present invention is rational in infrastructure, and is easy for operation, alleviated medical personnel's labor intensity, practiced thrift the nursing time, time saving and energy saving, also thoroughly avoided bubble to get in the patient vessel, makes transfusion safer, is a kind of ideal exhaust transfusion device of exempting from.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1. bottle plug puncture unit, 2. dropping funnel, 3. dropper, 4. intake chute, 5. drain post, 6. transfusion catheter, 7. drain cover, 8. flow regulator, 9. liquid medicine filter, 10. venoclysis needle.
The specific embodiment
As can be seen from Figure 1, a kind of exhaust transfusion device of exempting from includes bottle plug puncture unit 1, the dropping funnel 2 of being with dropper 3, liquid medicine filter 9, venoclysis needle 10 etc.By transfusion catheter 6 they are chained together, a flow actuator 8 is also installed in transfusion catheter 6 outsides between dropping funnel 2 and the liquid medicine filter 9.The concrete composition structure of bottle plug puncture unit 1, liquid medicine filter 9, flow regulator 8, venoclysis needle 10 and they belong to prior art with being connected of transfusion catheter 6.
Dropping funnel according to the invention 2 middle parts are provided with a drain cover 7, and drain cover 7 is installed with dropping funnel 2 inwall interference fit, and drain cover 7 appearances are provided with the intake chute 4 of downward conducting.Said drain cover 7 is a cap structure, and its appearance is provided with the intake chute 4 of three conductings.Be provided with a drain post 5 in the space that drain cover 7 and dropping funnel 2 bottoms form, drain post 5 is adhesively fixed with the outlet of dropping funnel 2, and is communicated with bottom transfusion catheter 6.
The inlet of drain post 5 according to the invention in dropping funnel 2 is positioned at the top of drain cover 7 bottom cover mouths.That is to say that drain post 5 stretches into drain cover 7 cover mouths, in dropping funnel 2, drain post 5 inlets are higher than the horizontal plane at drain cover 7 bottom cover mouths place.Like this, the transfusion initial period, medicinal liquid flows into from bottle plug puncture unit 1, oozes from dropper 3; Intake chute 4 on the entering drain cover 7 drop by drop, because the intake chute of drain cover 7 is very shallow, medicinal liquid can not flow down under capillary effect, but assembles on the top of drain cover; Form the liquid level of certain altitude, along with the rising of liquid level, the weight of medicinal liquid increases gradually; When the weight of medicinal liquid during greater than surface tension, medicinal liquid flows down along intake chute 4, continues the space accumulated that forms in drain cover 7 and dropping funnel 2 bottoms; Along with the rising of liquid level, the air in the space is discharged along the endoporus of drain post 5 and is got into transfusion catheter 6, discharges from venoclysis needle 10.When air was concentrated emptying, medicinal liquid began to get into continuously transfusion catheter, got into human body through flow regulator 8, liquid medicine filter 9, venoclysis needle 10.Like this, in whole infusion process, the medicinal liquid of entrapped air can not appear in the transfusion catheter.Thereby when having avoided transfusion, sneak into bubble in the transfusion catheter inner liquid medicine, saved " aerofluxus bubble " operation of transfusion, alleviated medical personnel's labor intensity, practiced thrift the nursing time, time saving and energy saving, exempt from aerofluxus, handled easily.
