Description

Venous transfusion medicinal liquid dissolving dispenser

This utility model relates to a kind of medical device, particularly a kind of venous transfusion medicinal liquid dissolving dispenser.

Prepare to the medicinal liquid of venous patient transfusion at present, all be to puncture the medicament bottle stopper with syringe needle therefrom to extract medicament again out, take out back reuse punctures transfusion bottle stopper, medicament is injected in the infusion bottle, the Infusion bottle lid if the big need of pharmaceutical quantities repeatedly puncture, especially powder medicament, need at first sucking-off diluent from infusion bottle, diluent is injected each powder bottle, treat the sucking-off one by one of medicated powder dissolving back reuse syringe, be injected in the infusion bottle, this repeated multiple times puncture bottle stopper medicinal liquid on the one hand easily pollutes, and is time-consuming; On the other hand, easily with inabundant dissolved pharmacy particle, plug microgranule and other pyrogen material are brought medicinal liquid into, cause iatrogenic diseases such as phlebitis, pulmonary meat thatch are swollen, blood vessel embolism.The number of times and the pollution of syringe needle puncture bottle stopper when making up a prescription for minimizing, Chinese patent CN2077299u discloses a kind of disposable medicine dissolving and adding appliance, its actuator by air bag, conduit, syringe needle and an on-off action is formed by connecting, this medicine dissolving and adding appliance, though the medicament of needs can be drawn onto air bag, join in the infusion bottle again, but its sterilization difficulty and intracavity gas thereof easily cause liquid medicine contamination on the one hand, undissolved on the other hand pharmacy particle, pyrogen materials such as bottle stopper microgranule still enter medicinal liquid, air bag is difficult to control simultaneously, and operation inconvenience easily causes the medicament loss.

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy to operate, effectively prevent the venous transfusion medicinal liquid dissolving dispenser that medicament pollutes.But this dispenser is once finished powder medicament realization close dissolving and dosing the injection drug continuous dosing, but and pyrogen materials such as undissolved pharmacy particle of filtering and bottle stopper microgranule.

The purpose of this utility model realizes by following technical proposals:

The needle holder of design one band arm, arm, syringe needle tube and needle stand pipe meet are provided with a transfer valve, connect a filter on the arm, and link to each other with infusion bottle by the conduit of band syringe needle, and the needle holder front end links to each other with injection needle, and its rear end links to each other with syringe cylinder.

Also filter can be linked to each other with syringe needle, link to each other with arm by conduit again.Said filter is that upper and lower threaded filter head housings and the filter disc in it are formed, and the filter disc aperture is 0.45～0.60um.

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 is a kind of needle holder cutaway view of the present utility model.

Below with reference to the accompanying drawings, in conjunction with the embodiments this utility model is further described: as shown in Figure 1, the needle holder of design one band arm 4, the syringe needle tube 2 of needle holder front end is provided with a transfer valve 3 with the intersection of arm 4 and needle stand pipe 8, said transfer valve valve core is sphere or cylindricality, and valve core is provided with two not at grade through holes, wherein has one to be the square through hole, another is a clear opening, and the two is 30～60 ℃ of angles of the crossing.Needle holder also can be designed to tee T as shown in Figure 2, and transfer valve is designed to the slide-valve 11 with cannelure.By sliding stem 10 move left and right, needle stand 8 is communicated respectively with syringe needle tube 2 or arm 4.The needle holder of second kind of structure, its valve core also can be designed to the cylindricality or the spherical valve core of a band trapezoidal hole.Arm links to each other with filter 6 one ends by conduit 5, and said filter is formed for the upper and lower shell and the intermediary screen plate of threaded or clamping member, and the filter other end links to each other with syringe needle, and syringe needle links to each other with infusion bottle.Also filter one end can be connected on the arm, the other end links to each other with the conduit of band syringe needle, and syringe needle links to each other with infusion bottle, and the needle stand pipe of needle holder rear end links to each other with syringe cylinder, and needle holder front end syringe needle tube links to each other with injection needle.During use, if injection, transfer valve is allocated to the needle stand pipe to communicate with syringe needle tube, and arm is closed, in the syringe needle insertion injection bottle with the needle holder front end injection is sucked in the syringe, stir transfer valve then to arm, the needle stand pipe is opened, and syringe needle tube is closed, injection is injected infusion bottle, in order to prevent liquid waste, can come the resorption transfusion for several times, conduit is washed, if powder, then earlier transfer valve is allocated to arm, the needle stand pipe communicates, and liquid in the infusion bottle is drawn in the syringe, again transfer valve being allocated to arm closes, syringe needle tube communicates with the needle stand pipe, and liquid is injected powder, treats after the medicament dissolving medicinal liquid to be sucked syringe, by the transfer valve conversion, medicinal liquid is injected in the infusion bottle again.In the time of need not making up a prescription, conduit can be separated with arm with arm or with filter, be hung on the infusion bottle top and make the infusion bottle air inlet pipe.

From foregoing description as can be known, the purpose of this utility model can realize, it only needs that not only infusion bottle plug and ampoule are filled in capable one-time puncture just can finish the medicament dissolving, process for preparation such as interpolations, and the assurance medicinal liquid is prepared and is carried out in confined conditions, reduce and pollute, but do not dissolve pharmacy particle completely by the filter disc filtering simultaneously, pyrogen materials such as plug microgranule significantly reduce the side effect to patient, venous transfusion medicinal liquid dissolving dispenser is convenient to sterilization simultaneously, uses easy to operate.
