Sterile automatic dispenser and using method thereof

Abstract

The invention provides a sterile automatic dispenser and a using method thereof. The dispenser comprises a solvent bottle puncture needle, a base and a vial puncture needle, the solvent bottle puncture needle is provided with a first channel, the vial puncture needle is provided with a second channel and a third channel, the first channel is in communication with the second channel, the base is provided with a joint, the joint is used for being connected with a syringe, the third channel is communicated with the joint and the syringe, a suction hole is formed in the bottom end of the vial puncture needle, and the suction hole is connected to the second channel. The process of pumping and injecting a liquid medicine in the whole dispensing process is a sterile operation in a sealed environment, and the liquid medicine is not in contact with the outside air. In addition, it is only necessary to puncture an infusion bottle and a vial rubber stopper once, the entire process of manual dispensing is completed, and the damage of the particulate pollution caused by repeating puncturing of the rubber stopper to a human body is reduced.

Description

technical field [0001] The invention relates to an aseptic automatic dispensing device. Background technique [0002] For clinical intravenous medication, the mixing and dispensing work of medical staff is heavy. Currently, clinical intravenous medication is mainly powder injection or freeze-dried powder, which is packaged in vials. The dispensing method is manual mixing and mixing with various dispensers. [0003] The routine steps of manual mixing and deployment are as follows: (1) puncture the rubber stopper of the solvent infusion bottle with a syringe, draw the corresponding dose of solvent injection from the solvent bottle according to the drug dose, (2) then puncture the rubber stopper of the vial respectively, and inject an appropriate amount of solvent injection Put it into the vial, (3) Shake the vial vigorously to fully dissolve the powder in the vial, (4) puncture the vial with a syringe again, and suck the dissolved medicine back into the syringe. After withdra...

AI Technical Summary

Problems solved by technology

The above statements show that the medical staff are cumbersome to operate and cannot strictly implement the aseptic operation specifications. In an open dispensing environment, repeated puncture and injection of the drug solution will increase the probability of microbial contamination of the drug solution in the air.

More importantly, in the above-mentioned conventional dispensing method, the rubber stopper of the infusion bottle cap and the rubber stopper of the vial are repeatedly punctured, and the tiny particles of impurities from the rubber stopper that fall off will be brought into the liquid medicine, causing particle pollution, and those contaminated by particles The liquid medicine will cause serious harm to the human body along with the blood circulation of the human body. For example, red blood cells are easy to condense on the particles to form thrombus to block blood vessels, enter the pulmonary capillaries, affect lung function, cause thrombocytopenia and allergic reactions, stimulate tissue inflammation and form lumps Wait

In addition, chemotherapy drugs, cytotoxic drugs, and drugs that are genotoxic, carcinogenic, teratogenic, or harmful to fertility, and toxic to organs and tissues, once leaked, will cause toxic or corrosive injuries to medical staff

[0004] The dispensing devices or dispensing devices appearing on the market have the following characteristics: the dispensing device injects the solvent in the infusion bottle into the vial, and air holes must be left on the dispensing device. The entire dispensing process is directly connected to the outside world. Even if a filter membrane is installed, Still can't block the contact between the liquid medicine and the outside world

More importantly, to inject the solvent in the infusion bottle into the vial, the medical personnel need to squeeze the plastic infusion bottle hard, and the gas in the infusion bottle and the vial will be discharged through the air hole on the dispenser. After letting go, due to the return of the plastic infusion bottle suction, and suck the outside air back into the vials and infusion bottles, and the medicines and infusions in the vials and infusion bottles are processed under aseptic conditions, and the products are sterile products, so that the device will A large number of microorganisms in the air are brought into the bottle, seriously contaminating sterile powder injections and sterile infusions

In addition, each bottle of infusion requires the medical staff to squeeze the infusion bottle hard, and if it is a hard packaging such as a glass bottle, it cannot be squeezed, so this device cannot be really suitable for clinical use and is facing elimination.
