Description

The infusion bottle that has transfusion air inlet barrier means

The utility model discloses venous transfusion inlet air filtration technology, belong to the device in the medical aid.

The transfusion device of present clinical use, extensively adopt gravity bottom pouring type infusion set, this infusion set must have infusion bottle, tube for transfusion and air inlet pipe are formed, its air inlet pipe of traditional infusion model is that tip-tilted rubber tube of a syringe needle connection has just been operated from the transfusion bottle stopper insertion, this air inlet pipe requires to differ greatly from health care, because along with urbanization, industrialized development, the increase of population density, dust in the air, pollutant, malignant bacteria is more and more, the air of running into infusion bottle from air inlet pipe all passes through to roll with medicinal liquid and contacts, on the medicinal liquid face, form air pressure then, medicinal liquid is with after sordid air contacts, medicinal liquid will be stained with pollutant and pathogenic bacterium, in the injection human body, gently then influence the heavy then threat to life safety of health, for this reason, people adopt things such as absorbent cotton or sponge with air filtration on the air inlet pipeline of infusion bottle, but this filter effect is very poor, so many inventors have created and using liquid is set on the air inlet pipe path has come filtered air and then enter in the infusion bottle, example utility model patent 86208756,882003569, patent of invention 86103312, the effect of these innovation and creation filtration, purification air is significantly improved, but because the approach position of filtration, purification is outside bottle, to complicated on the transfusion operation.The more important thing is the air admission infusion bottle of filtration, purification, still must roll with medicinal liquid contacts, and therefore, medicinal liquid still has the contaminated probability of being stained with pathogenic bacteria, and is not thorough to the degree of purification of medicinal liquid.

The purpose of this utility model provide a kind of thorough solution transfusion air inlet can with the isolated way of medicinal liquid, promptly be to adopt transfusion air inlet and the isolated method of medicinal liquid, thereby air inlet and the contactless chance of bottle inner liquid medicine ensure the purification of medicinal liquid, improve injection quality, ensure the safety of infusing.

The utility model is achieved like this, a kind of infusion bottle that has transfusion air inlet barrier means, it is by bottle, medicinal liquid, bottle stopper and capping are formed, it is characterized in that in bottle, having one by bladder tank, the sealed transfusion inlet channel that plug-in unit and bottle stopper air inlet are formed, the transfusion air inlet is risen greatly in bladder tank and with air inlet gradually, air inlet and medicinal liquid be contactless has carried out isolation, its plug-in unit is the cylinder of a hollow, plug-in unit axle center through-hole aperture equates with the air inlet at bottle stopper center and aligns, the cylinder lower semisection is the face of cylinder, upper semisection is the zigzag cylinder, two posts become airbag cup of intersection cover, the face of cylinder and bottle stopper are stationary fit and are tightly connected, sawtooth cylinder and airbag mouth are tightly connected, the bladder tank sealing is air tight, when having pressure, infusion bottle is not compressed in the airbag cup, the airbag cup does not have the end, with producing draught head inside and outside the infusion bottle, the air admission passage magnifies bladder tank gradually runs out of the last airbag injection of airbag cup bottle, airbag volume and airbag material volume sum equal infusion bottle inner liquid medicine volume, the cup footpath is slightly less than bottleneck, the cup cervical region has a medicinal liquid pod apertures, there is an air inlet at the bottle stopper center, the inboard air inlet periphery of bottle stopper has one to be the column sleeve of stationary fit with plug-in unit, and it partly is conventional structure that bottle stopper and mouth of infusion bottle are sealed and matched.The utility model is described in further detail with Figure of description below.

Accompanying drawing 1 is this utility model work simplified schematic diagram,

Accompanying drawing 2 is an airbag cup structure sketch

Accompanying drawing 3 is the dongle configuration sketch

Accompanying drawing 4 is the transfusion bottle stopper structure diagram

Accompanying drawing 5 is the transfusion bottle stopper diagrammatic top view

1-5 with reference to the accompanying drawings, 1 is bladder tank among the figure, 2 is plug-in unit, 3 is the air inlet at bottle stopper center, chat as mentioned by this three and to form infusion bottle transfusion inlet channel, be illustrated as airbag near being full of the bottle chamber, 4 is the airbag cup, 5 is the medicinal liquid pod apertures of gas cup cervical region, having this hole infusion bottle inner liquid medicine to flow out the bottle inner liquid medicine from pod apertures can not accumulate in the cup, 6 is the reinforcement of three symmetrical distributions between plug-in unit column sleeve and the bottle stopper on the Bottle stopper body, prevent the plug-in unit of inlet channel, airbag cup and airbag rock, according to the requirement of medical and health to medical device, bladder tank, airbag cup and plug-in unit can be made with non-toxic material such as plastics etc., bottle stopper also has seal request to make with nontoxic rubber, and all the other are structure manufacturing routinely all.

This utility model will infuse the air inlet utilization be arranged on the bottle an intravital inlet channel, air inlet is store in airbag, air and the contactless isolated situation of medicinal liquid in the infusion bottle have been realized entering, so thorough airborne pollution is foreclosed, keep the pure requirement of medicinal liquid, reach safe and sanitary transfusion, this utility model and ensured that transfusion is used up and can not cause air input patient's blood vessel to guarantee personal safety.The transfusion inlet channel is arranged on has brought a lot of convenience in the bottle medical work personnel transfusion operation simultaneously, during operation, open the bottle cap envelope, inlet channel is just open-minded voluntarily, insert tube for transfusion and enter transfusion state immediately, have the medical aid articles for use of application value.
