Description

The accurate molten medicine entry needle of single use

Technical field this utility model relates to medical instruments field, belongs to 6815 injection puncture instruments by Chinese Medical Device Manufacturers classification.

Background technology is current, existing " single use aseptic injection pin ", in molten medicine and injection manipulation, when syringe needle puncture molten medicine bottle rubber stopper or cut open aspiration medicinal liquid bottle from the peace broken time, cannot avoid rubber stopper microgranule and peace cut open the broken last microgranule of bottle glass to the pollution of medicinal liquid.The name of being declared by Yuan Shumin for 1998 is called " single use side hole soluble medicine insertion bottle needle ", the patent No. is the utility model patent of ZL98249136.0, be a routine of great value invention, it efficiently solves the problem of rubber stopper particle contamination in molten medicine operating process.But how to avoid when to patient's injection with to transfusion device dosing, rubber stopper microgranule and peace cut open the problem that the broken last microgranule of bottle glass pollutes medicinal liquid in aspiration medicinal liquid process, are but the problems never solved.

Summary of the invention the purpose of this utility model is the deficiency making up " single use aseptic injection pin "; there is provided a kind of novel " the accurate molten medicine entry needle of single use "; to solve in molten medicine, injection and dosing process, rubber stopper microgranule or peace cut open the trifling pollution problem to medicinal liquid of bottle cullet.

Accompanying drawing illustrates that this utility model " the accurate molten medicine entry needle of single use " provides two profiles number.Figure mono-is the structure chart of molten medicine needle guard in outside, (1) aseptic injection pin needle stand; (2) injection needle for dispensing needle stand; (3) aseptic injection pin needle tubing; (4) injection needle for dispensing needle tubing; (5) liquid medicine filtering membrane; (6) injection needle for dispensing side opening.Figure bis-is the structure chart of aseptic injection needle guard in outside, (1) aseptic injection pin needle stand; (3) aseptic injection pin needle tubing; (5) liquid medicine filtering membrane.

Detailed description of the invention this utility model is achieved in that the accurate molten medicine entry needle of the single use of this utility model for the taked technical scheme that solves the problem, and forms primarily of " single use injection needle for dispensing ", " single use aseptic injection pin " and " liquid medicine filtering membrane ".In shape, structure and combination thereof, this utility model technical characteristic different from immediate prior art is: it has two profiles number, the first model is: one is equipped with " liquid medicine filtering membrane " " single use injection needle for dispensing ", be enclosed within the outside of another " single use aseptic injection pin ", be combined into one, be arranged on one " disposable sterilized syringe ".The second model is: one is equipped with " liquid medicine filtering membrane " " single use aseptic injection pin ", is enclosed within the outside of another " single use aseptic injection pin ", is combined into one, be arranged on one " disposable sterilized syringe ".During use, two profiles number can be chosen any one kind of them.Front or to before transfusion device dosing whenever injecting to patient; all first must carry out the operation of molten medicine and aspiration medicinal liquid; now; be enclosed within " the disposable injection needle for dispensing " or " disposable sterile injector " of outside; by " liquid medicine filtering membrane ", rubber stopper microgranule or peace will be cutd open the broken trifling of bottle and filter out.After molten medicine or aspiration medicinal liquid have operated, by be enclosed within outside, " the single use injection needle for dispensing " or " single use aseptic injection pin " that complete medical filtration pull up, at this moment, syringe is only left one " single use aseptic injection pin " and free of contamination medicinal liquid, can completes thus to patient's injection or infusion medicine-feeding.

The beneficial effects of the utility model are: avoid injection and infusion medicine-feeding operating process in rubber stopper microgranule and peace cut open the trifling pollution of bottle glass, meanwhile, because two entry needle combinations of inner and outside share syringes, thus more convenient operation, shorten the operating time, and save cost.Like this, just practical value of the present utility model and economic worth is achieved well.

Below, enumerate example to further illustrate: when needs of patients injection or transfusion device need dosing, first nurse gets the peace that medicinal liquid is housed ready and cuts open bottle, after bottle is broken from top, uses the syringe that " the accurate molten medicine entry needle of single use " is housed, complete the operation that suction peace cuts open bottle inner liquid medicine, then, grip is pulled up from syringe at an entry needle of outside, with the syringe only remaining an aseptic injection pin, implement injection to patient, or give transfusion device dosing.If what need molten medicine is bottle with rubber stopper, then first carries out molten medicine with the entry needle being enclosed within outside, inhale medicine, then, the entry needle being enclosed within outside is pulled up from syringe, with the syringe of an only surplus aseptic injection pin to transfusion device dosing.The two profiles number of " the accurate molten medicine entry needle of single use "; each operation; arbitrarily can use one; the effect avoiding rubber stopper microgranule or peace to cut open the broken last particle contamination medicinal liquid of bottle glass can be played; and only use a syringe; save the time changing syringe, save the cost of product.

Claims (1)

1. the accurate molten medicine entry needle of single use, be made up of single use injection needle for dispensing, single use aseptic injection pin and liquid medicine filtering membrane, it is characterized in that: single use injection needle for dispensing is enclosed within outside single use aseptic injection pin, to be installed on same syringe or single use aseptic injection needle guard that two specifications are different together, be installed on same syringe; Cover syringe needle tube inner chamber top is outside provided with filters rubber stopper microgranule and the trifling liquid medicine filtering membrane of ampoule bottle cullet.
