An infusion channel which is communicated with the infusion side needle hole is arranged in the needle seat, the needle seat is equipped with a connecting hole which is connected with a syringe, the connecting hole is communicated with the breathing channel, the lower portion of the needle seat is equipped with an auxiliary needle, the lower end of the auxiliary needle is closed with an auxiliary needle tip, the side portion of the auxiliary needle tip is equipped with a liquid outlet hole, and the liquid outlet hole is communicated with the infusion channel. Drug can be rapidly dissolved and dispensed through using the casing dispensing device, because the whole process of dissolving and dispensing the drug is done under the closed condition, the opportunity of drug pollution is greatly reduced.

Description

A kind of sleeve pipe dispenser

Technical field

This utility model relates to a kind of medical apparatus, specifically is a kind of sleeve pipe dispenser.

Background technology

Clinically, because of in molten medicine, medicine bottle external and internal pressure imbalance when making up a prescription, need substitution gas and medicinal liquid solvent repeatedly, the labor intensity and the operating time that have increased the molten medicine of nurse greatly and made up a prescription, complex operation, inconvenience, while is bottle stopper because syringe repeatedly punctures, and the syringe that has medicinal liquid is exposed in the air to be operated, and has increased the chance of drug contamination greatly.

The utility model content

The technical problems to be solved in the utility model provides the fast instant medicine of a kind of energy, makes up a prescription and can reduce the sleeve pipe dispenser of drug contamination chance.

For solving the problems of the technologies described above, a kind of sleeve pipe dispenser that is provided, comprise syringe needle, the bottom of syringe needle is inserted on the needle stand, and its construction features is: the upper end of syringe needle is airtight to be needle point, and syringe needle is provided with air inlet side pin hole and transfusion side pin hole from top to down successively, be provided with sealing ring between air inlet side pin hole and the transfusion side pin hole, be provided with breather in the syringe needle, the breather upper end communicates with air inlet side pin hole, and its lower end airway interior with being arranged on needle stand communicates; Be provided with the infusion channel that communicates with the side pin hole of infusing in the needle stand, needle stand is provided with the connecting hole that can connect syringe, and connecting hole communicates with airway, secondary syringe needle is equipped with in the bottom of needle stand, the lower end of secondary syringe needle is airtight to be secondary needle point, and the sidepiece of secondary syringe needle is provided with liquid outlet, and liquid outlet communicates with infusion channel.

This utility model is so to use: syringe needle is inserted in the powder bottle, secondary syringe needle is inserted in fluid bag or the liquid bottles, keep fluid bag or liquid bottles to be higher than powder bottle, simultaneously syringe is inserted in the connecting hole on the needle stand, utilize syringe to make and produce negative pressure in the powder bottle, liquid in fluid bag or the liquid bottles is under the effect of gravity and pressure, by secondary syringe needle, infusion channel, syringe needle flows in the powder bottle from transfusion side pin hole, when the liquid of waiting to enter powder bottle reaches instructions for use, rock powder bottle and carry out molten medicine, after the dissolving fully, powder bottle is positioned on the position that is higher than fluid bag or liquid bottles, utilize syringe to make and produce malleation in the powder bottle, the medicinal liquid after the dissolving flows back in fluid bag or the liquid bottles under the effect of gravity and pressure, thereby finishes whole molten medicine, the process of making up a prescription.Use this utility model can carry out molten medicine fast, make up a prescription; Because whole molten medicine, the process of making up a prescription all are to carry out under airtight condition, have significantly reduced the chance of drug contamination.
