Description

Storage type powder injection combination dosing syringe

technical field

The utility model relates to a drug-storage type powder injection combination drug-dosing syringe.

Background technique

In the past, medical syringes, medicine bottles and diluents were relatively independent. When the nurse injects the powder (as penicillin etc.) to the patient, the diluent must be pulled out with a syringe and then pricked into the medicine bottle, the diluent is released to dissolve the powder, and then the injection can be inhaled into the syringe. The entire operation process uses a lot of materials, the procedures are complicated, the syringes are easily contaminated, and there are often medical accidents caused by wrong medicines. Someone in China has applied for the patent of "powder injection with pressure medicine bottle type syringe", which is to put the powder in an inner container, rely on the spine needle at the front end of the push handle to pierce the inner container, and make the diluent in the solute bottle rely on the pressure and the drug powder. Mix and mix well before injecting. Though this injector is simple in structure, still there is not quite ideal part.

Contents of utility models

The technical problem to be solved by the utility model is to provide a medicine-storing powder injection combination dosing syringe with novel structure and simple operation in order to overcome the deficiencies described in the prior art.

The technical improvement scheme of the utility model is: a solvent bottle with a diluent is socketed with the solute bottle, a connecting pipe is connected between the solvent bottle and the solute bottle, and a piston and a push handle are connected at the end of the solvent bottle.

The further technical improvement of the utility model is: the solvent bottle and the solute bottle are slidingly matched. An inner stopper is provided in the solute bottle. Said connecting pipe is a hollow pipe with pointed ends, and a limiting plate is also arranged on the connecting pipe. A threaded needle sleeve made of flexible plastic is arranged outside the double-pointed needle, and a limiting plate is also provided on the double-pointed needle.

Due to the unique and novel structural design of the syringe, the diluent can be injected into the solute bottle through the connecting tube under the external force of pushing the push handle and the piston, and the medicine powder is melted and mixed, and then directly injected into the patient or added to the infusion bottle. It is particularly simple, and for nurses, it can reduce the operation steps, let alone the phenomenon of wrong medicine filling, and reduce the psychological burden of nurses. Because a threaded needle sleeve made of flexible plastic is added outside the double-pointed needle, the degree of sterility is high, and it will not be polluted or cross-contaminated. When the syringe is produced, the required medicinal powder and the corresponding diluent are loaded according to the dosage requirements. The whole syringe is packed in a sterile package for one-time use, and there is no possibility of repeated use. Compared with the commonly used medicine powder, ordinary syringe and diluent, the overall cost of the syringe is lower, and the more important thing is that the operation is simple and convenient, the labor intensity of nurses is reduced, there is no transfer of powder or diluent, and it is suitable for large-scale production, especially for Daily use of hospital nurses performing intramuscular injection of powder injections, dosing into infusion bottles and dosing through infusion bottle catheters.

Description of drawings

Accompanying drawing is the overall structural representation of the utility model.

Detailed ways

As shown in the accompanying drawings, the utility model is mainly composed of a solvent bottle 10, a solute bottle 15, a double-pointed needle 13, a connecting pipe 11, and an inner plug 3. Wherein, the inner plug 3 is contained in the solute bottle 15, and the solvent bottle 10 containing the diluent 6 is located above the inner plug 3, and the ports of the solvent bottle 10 and the solute bottle 15 are all equipped with medical rubber or other non-toxic rubber. The sealing plug 5,2. Both ends of the connecting tube 11 and the double-pointed needle 13 are pointed, and one end of the double-pointed needle 13 is inserted into the sealing plug 2; while one end of the connecting tube 11 is inserted into the sealing plug 5, and the other end is inserted into the inner plug 3 in the pit. The protective cover 9 covers the solvent bottle 10, the piston 7 and the push handle 8, and cooperates with the solute bottle 15 upper edge. Both the communicating tube 11 and the double-pointed needle 13 are fixed with limiting pieces 4 and 14 . The end of the solute bottle 15 is connected with a thin threaded needle sheath 1 made of flexible non-toxic plastic.

When this syringe is manufactured, the required medicated powder 12 is filled in the solute bottle by dosage, and the diluent 6 of the corresponding dose is filled in the solvent bottle. When injecting the patient or needing to add medicine to the infusion bottle, first remove the protective cover and press the push handle and the piston downward. Under the action of external force, the connecting tube will pierce the sealing plug upward while the solvent bottle moves downward. And pierce the inner plug downward. Due to the action of the push handle and the piston, the diluent will be sprayed into the solute bottle through the connecting pipe to dissolve and mix the powder. Then align the double-pointed needle and the needle cover with the injection site or the infusion bottle and insert it, and the reaction force will cause the double-pointed needle to pierce the sealing plug 2 . At the same time, the needle cover will be compressed to the limiting piece due to the blocking of the skin at the injection site or the rubber stopper of the infusion bottle. Continue to push the push handle to make the medicinal solution injected into the human body or the infusion bottle under the effect of pressure, thus completing one operation.
