Description
Technical field
This utility model relates to clinical transfusion aseptic medical equipment, particularly relate to a kind of stop liquid from aerofluxus can liquid transfusion device only.
Background technology
At present, use common transfusion primarily of bottle plug puncture unit protective cap, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, dropper, dropping funnel, transfusion long duct, transfusion long duct, medicine filter and single use intravenous needle composition in medical field clinically.When using general infusion set transfusion, manually must squeeze dropping funnel, could medicinal liquid be introduced in dropping funnel from infusion bottle, enter in dropping funnel process at medicinal liquid, medicinal liquid easily by the gas press-in transfusion long duct in dropping funnel, produces bubble in pipe, simultaneously, due to the effect of tube for transfusion inner wall surface tension force, inwall easily adsorbs a small amount of bubble, and exclusion process is difficult, loaded down with trivial details, time-consuming, if can not get rid of bubble very well, bubble enters in patient body with medicinal liquid, easily causes the danger such as aeroembolism.Current medical personnel to patient fluid infusion's front exhaust mode are being: after bottle plug puncture unit inserts infusion bottle; be inverted dropping funnel; squeezing dropping funnel with hands makes medicinal liquid enter in dropping funnel; until dropping funnel inner liquid medicine reach a certain amount of after; put down dropping funnel; as far as possible by most of removal of bubbles; for inwall absorption bubble; need medical personnel's springing transfusion catheter repeatedly; bubble is rushed in dropping funnel, whole process is time-consuming, effort, loaded down with trivial details, add the working strength of medical personnel; simultaneously when being critically ill patient in the face of urgent transfusion and rescue, serious consequence will be caused.
And, the usual one-to-many of medical personnel look after patient fluid infusion, the amount of labour, intensity are all very large, in infusion process, normal appearance fails change infusion bottle in time or pull out transfusion needle because of medical personnel, patient or family numbers of patients, cause in blood backflow transfusion catheter or bubble enters in patient body and causes the adverse consequencess such as aeroembolism, bring heavy mental burden to medical personnel, patient or family numbers of patients.
In addition; by improving general infusion set dropping funnel structure or add only liquid adnexa near dropping funnel; though can realize simply stopping liquid and aerofluxus; but still effectively cannot solve aerofluxus bubble problem when changing infusion bottle, meanwhile, simple only liquid causes part liquor residue at dropping funnel with in transfusion long duct; can not well enter in patient body; cause curative liquor quantity not sufficient and liquid waste, especially when the few dosage of needs of patients input, expensive help medicinal liquid are critically ill in urgent rescue, will serious consequence be caused.
Therefore, for above-mentioned general infusion set and improvement transfusion device Problems existing, in clinical transfusion process, use a kind of transfusion device possessing automatic vent, automatic liquid-stopping and tube for transfusion clean liquid function particularly important.

This utility model also disclosed a kind of stop liquid from aerofluxus can the safe infusion method of liquid transfusion device only, concrete steps are as follows: step one: first take off the rubber protective cap 16 be arranged on the aerofluxus post 17 of dropping funnel upper cover 06, close the vent plug 08 be arranged on dropping funnel base 10, close flow regulator 12;
Step 2: pull out protective sleeve for bottle stopper puncture outfit 16, then bottle plug puncture unit 03 is inserted in transfusion bottle stopper, open air inlet seat 02, naturally transfusion device is hung, open annular water and stop 05, medicinal liquid flows into intracavity on dropping funnel 07 by transfusion tubulature 04, along with liquid level rises, because the only liquid film 20 on separate layer 21 is soaked rear stuffiness, in dropping funnel, gas is pressed into the hollow structure of stop 18 and aerofluxus post 17 gradually by the air-filtering membrane 19 on the endoporus of stop 18 bottom and is discharged dropping funnel 07 by the steam vent on aerofluxus post 17, effectively prevent the generation of bubble and prevent bubble from entering in transfusion long duct 11, make aerofluxus more convenient, in addition, when changing infusion bottle, because automatic vent plays a role, do not need again to be exhausted process, directly bottle plug puncture unit 03 is inserted new infusion bottle, efficiently solve the problem that general infusion set replacing infusion bottle needs aerofluxus again, reduce the labor intensity of medical personnel,
Step 3: on dropping funnel 07, the medicinal liquid of intracavity instills dropping funnel 07 time intracavity by the only liquid film 20 on separate layer 21, and enters transfusion long duct 11 by dropping funnel base 10;
Step 4: when medicinal liquid liquid level did not have the air-filtering membrane 19 on the endoporus of stop 18 bottom; air-filtering membrane 19 on the endoporus of stop 18 bottom soaks by medicinal liquid; the medicinal liquid contacted with air-filtering membrane 19 is not by air-filtering membrane 19; now also isolated by medicinal liquid between residual air and air-filtering membrane 19 in dropping funnel 07 and no longer discharge dropping funnel 07; medicinal liquid continues instillation dropping funnel 07 subsequently; space in dropping funnel 07 reduces gradually; residual air will produce pressure; when the pressure that residual air produces is enough to stop medicinal liquid instillation, dropping funnel herb liquid liquid level will no longer raise;
Step 5: when medicinal liquid liquid level did not have the air-filtering membrane 19 on the endoporus of stop 18 bottom and no longer rose, get final product regulable control flow calorimeter 12, make medicinal liquid enter transfusion long duct 11 and flow out 15 from disposable venous infusion needle, gas in emptying transfusion long duct 11, close flow regulator 12, puncture venoclysis needle 15, and then open flow regulator 12, regulate flow, get final product normal infusion;
Step 6: when infusion bottle inner liquid medicine is totally lost, residual liquor all enters dropping funnel 07 cavity of resorption, dropping funnel base 10 is inner and infuse in long duct 11, because the only liquid film 20 on separate layer 21 is soaked rear stuffiness, dropping funnel cavity of resorption, dropping funnel chassis interior and transfusion long duct herb liquid automatically stop flowing and resting on dropping funnel 07 cavity of resorption under suction function, dropping funnel base 10 is inner and infuse in long duct 11, reach the object of automatic liquid-stopping, simultaneously because automatic liquid-stopping plays a role, air is stoped to enter infusion pipeline, without the need to worrying that replacing causes blood backflow or gas to enter in patient body not in time and forms aeroembolism, reduce medical personnel, the heavy mental burden of patient and family numbers of patients,
Step 7: because automatic liquid-stopping exists, residual fraction medicinal liquid in transfusion long duct 11, now under Nurse safety operation, vent plug 08 on the left of dropping funnel base 10 is opened, removing suction function, automatic liquid-stopping effect was lost efficacy, be totally lost and rest on the residual liquor that dropping funnel base 10 is inner and infuse in long duct 11, due to the existence of the automatic clean liquid function of transfusion device, effectively prevent medicinal liquid can not well enter in patient body, cause curative liquor quantity not sufficient and liquid waste, especially rescue urgent the few dosage of needs of patients input of being critically ill, during expensive help medicinal liquid, serious consequence will be caused.
Last it is noted that obviously, above-described embodiment is only for this utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among the protection domain of this explanation.
