The bottle plug puncture unit 03 of Multifunctional safety transfusion system is as shown in Figure 1 provided with dismountable bottle plug puncture unit protective cap 01; the aerofluxus post 16 of dropping funnel upper cover 06 is as shown in Figure 2 provided with dismountable rubber protecting jacket 15, the liquid injection device 24 of dropping funnel upper cover 06 is provided with dismountable latex cap.
The safe infusion method of this utility model also disclosed a kind of Multifunctional safety transfusion system, realizes multifunctional safe infusion by following steps:
Step one: the rubber protective cap 15 first taking off aerofluxus post 16, closes vent plug 21, closes flow regulator 11;
Step 2: pull out protective sleeve for bottle stopper puncture outfit 01, 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, dropping funnel 07 need not be extruded, also dropping funnel 07 need not be inverted, medicinal liquid instills in dropping funnel 07 automatically, soft rubber cushion 26 due to floating block 20 lower end closes dropping funnel base 08 time drip hole, and medicinal liquid cannot enter in transfusion long duct 10, and medicinal liquid is stored in dropping funnel 07, along with the continuous increase of medicinal liquid, in dropping funnel 07, gas is pressed into steam vent eliminating dropping funnel 07 gradually;
Step 3: when waiting liquid level to arrive certain position, namely when medicinal liquid buoyancy is greater than floating block gravity, floating block 20 rises, soft rubber cushion 26 leaves dropping funnel base 08, medicinal liquid starts to enter transfusion long duct 10, effectively prevent the generation of bubble and prevent bubble from entering in transfusion long duct 10, make aerofluxus more convenient;
Step 4: when medicinal liquid liquid level did not have the air-filtering membrane 18 on the endoporus of stop 17 bottom, air-filtering membrane 18 on the endoporus of stop 17 bottom soaks by medicinal liquid, the medicinal liquid contacted with air-filtering membrane 18 is not by air-filtering membrane 18, now also isolated by medicinal liquid between residual air and air-filtering membrane 18 in dropping funnel 07 and no longer discharge dropping funnel, 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 07 herb liquid liquid level will no longer raise,
Step 5: after liquid level did not have the air-filtering membrane 18 of stop 17, then by controlling flow regulator 11, medicinal liquid is made to enter transfusion long duct 10, flow out from single use intravenous needle 14 endoporus, gas in emptying conduit, close flow regulator 11, puncture single use intravenous needle 14, open flow regulator 11, regulate flow, get final product normal infusion.There will not be in whole operating process and have bubble to enter in transfusion long duct 10 as general infusion set, 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 again to extrude dropping funnel, aerofluxus, reduce the labor intensity of medical personnel; When infusion bottle inner liquid medicine is totally lost;
Step 6: when infusion bottle inner liquid medicine is totally lost, floating block 20 reduces, it is inner with in transfusion long duct 10 that residual liquor all enters dropping funnel base 08, when the soft rubber cushion 26 of floating block lower end closes the opening of dropping funnel base 06 upper end, medicinal liquid automatically stops flowing and rests in dropping funnel base 08 inside and transfusion long duct 10, because automatic liquid-stopping plays a role, air is prevented to enter infusion pipeline, causing blood backflow to enter in patient body to dropping funnel or gas not in time forming aeroembolism without the need to worrying to change, reducing the heavy mental burden of medical personnel, patient and family numbers of patients;
Step 7: at the end of transfusion device transfusion; under Nurse safety operation, the vent plug 21 on dropping funnel base 08 is opened; removing suction function; automatic liquid-stopping effect was lost efficacy; be totally lost by residual liquor in infusion pipeline, avoiding medicinal liquid can not well enter in patient body, causes 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, 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.
