Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of hospital clinical nurse medicine dissolving and adding appliance, mainly comprises holder and push-pull device at fixed two parts, described holder comprises needle stand 1, needle stand 1 has puncture needle 2, puncture needle 2 inside is provided with intake and exhaust pin 5, and the tip of described exhaust needle 5 stretches out in described puncture needle 2; Be fixedly connected with medicine storage 6 above described needle stand 1, the position that communicates with air, medicine storage 6 top is provided with air filter 7, and described exhaust needle 5 is connected with described medicine storage 6; Described push-pull device at fixed comprises syringe 9, and syringe 9 front end is spun by the male-tapered interface 10 of inner conical interface 8 with described needle stand 1 side, and described syringe 9 inside is provided with push-pull bar 12.
Described puncture needle 2 inside is fluid passage 4, and described puncture needle 2 sidewall offers a fluid passage side opening 3, and described medicine storage 6 is vertically fixed on the top of needle stand 1; Described push-pull bar 12 top is fixedly connected with rubber piston 11, and afterbody is fixedly connected with push-pull bar handle 13; Described puncture needle 2 outer setting has protection needle guard 14.
Embodiment one:
1, powder bottle drawing liquid process: first taken off by the protection needle guard 14 on puncture needle 2, puncture needle 2 inserts in saline bottle bottle stopper, is slowly extracted out by the push-pull bar 12 that syringe 9 inside is arranged, and syringe 9 inside produces vacuum suction, extracts saline and enters in syringe 9.When extracting saline, extraneous gas enters into saline bottle by air filter 7, medicine storage 6, intake and exhaust pin 5 successively, through the filtration of air filter 7, avoids entering of dust in air, ensure that medicinal liquid is not contaminated.Because outside air enters in saline bottle by intake and exhaust pin 5, offset by the air pressure in saline bottle, air inlet defines the gas passage of one-in-and-one-out with the gas being extracted into syringe, thus makes pulling of push-pull bar in syringe very light.
2, the molten medicine process of powder bottle: be inserted into by puncture needle 2 in powder bottle bottle stopper, slowly promote push-pull bar 12, be injected in powder bottle by the saline in syringe 9, jog powder bottle dissolves completely to powder.When saline injects, the gas pressure produced in powder bottle is discharged in outside air through intake and exhaust pin 5, and air pressure is cancelled, and the gas pushed in aerofluxus and syringe 9 defines the gas passage of one-in-and-one-out, thus makes the promotion of push-pull bar in syringe very light.
3, powder bottle dosing process: slowly pull push-pull bar 12, liquid consoluet in powder bottle is withdrawn in syringe 9, in extraction, extraneous gas is by intake and exhaust pin 5 air inlet, enter in syringe 9 through air filter 7, medicine storage 6 successively, avoid entering of dust in air, ensure that medicinal liquid is not contaminated.Because outside air enters in powder bottle by intake and exhaust pin 5, offset by the air pressure in powder bottle, air inlet defines the gas passage of one-in-and-one-out with the gas being extracted into syringe.Now, in powder bottle, there is no gas pressure (malleation), when puncture needle 2 is extracted from powder bottle bottle stopper, do not produce injection, can not form aerosol yet.Slow promotion push-pull bar 12, injected in transfusion bag or infusion bottle by medicinal liquid consoluet in syringe 9, medicine dissolving and adding has operated.
Embodiment two:
1, injection bottle takes out medicine process: first taken off by the protection needle guard 14 on puncture needle 2; pull out the push-pull bar 12 in syringe 9 again; negative pressure is produced in syringe 9; the medicinal liquid in injection bottle is attracted to enter fluid passage 4 through fluid passage side opening 3; entered in syringe 9 by fluid passage 4 again, complete medicinal liquid extraction work.In drawing liquid operation, because the size of fluid passage side opening 3 is larger than the side opening of syringe, extracting liquid rapid operation is convenient.
2, injection bottle dosing process: slowly promote push-pull bar 12, injected in transfusion bag or infusion bottle by the medicinal liquid be pumped in syringe 9, feeding operations completes.
Embodiment three:
1, be with air pressure powder bottle drawing liquid process: first taken off by the protection needle guard 14 on puncture needle 2, puncture needle 2 inserts in saline bottle bottle stopper, slowly extracted out by the push-pull bar 12 that syringe 9 inside is arranged, syringe 9 inside produces vacuum suction, extracts saline and enters in syringe 9.When extracting saline, extraneous gas enters into saline bottle by air filter 7, medicine storage 6, intake and exhaust pin 5 successively, through the filtration of air filter 7, avoids entering of dust in air, ensure that medicinal liquid is not contaminated.Because outside air enters in saline bottle by intake and exhaust pin 5, offset by the air pressure in saline bottle, air inlet defines the gas passage of one-in-and-one-out with the gas being extracted into syringe, thus makes pulling of push-pull bar in syringe very light.
2, air pressure powder bottle molten medicine process is with: medicine dissolving and adding appliance is in molten medicine process, because powder bottle is inner with certain air pressure, be inserted in powder bottle bottle stopper process at puncture needle 2, medicine splash can be there is, the medicine that splash goes out enters into inside medicine storage 6 through intake and exhaust pin 5, avoid drug waste, ensure that the accurate of drug dose.Now, need by the push-pull bar 12 in push-and-pull syringe repeatedly, produce vacuum suction and the medicine in medicine storage 6 is sucked back in powder bottle by intake and exhaust pin 5.Now, slowly promote push-pull bar 12, push in powder bottle by the saline sucked in advance in syringe 9, jog powder bottle dissolves completely to powder.
3, dosing process: consoluet medicine is entered fluid passage 4 by fluid passage side opening 3, then be pumped in syringe 9 by fluid passage 4.Then, injected in transfusion bag or infusion bottle by the consoluet medicinal liquid in syringe 9, feeding operations completes.
Finally it should be noted that above embodiment only in order to the technical solution of the utility model to be described, not limitation ot it; Although with reference to previous embodiment to invention has been detailed description, it will be appreciated by those skilled in the art that it still can be modified to the technical scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
