Description
Technical Field
The utility model relates to a closed liquid medicine transfer system, and belongs to the field of liquid medicine preparation.
Background
Dispensing personnel involved in the dispensing and management of hazardous medical fluids are susceptible to damage from exposure to air and hazardous medical fluid vapors that can diffuse into the surrounding environment. As used herein, "hazardous liquid medicine" refers to any injectable material, the contact of which or the vapor of which can cause health hazards. Illustrative and non-limiting examples of such medical solutions include, but are not limited to, cytotoxins, antiviral agents, chemotherapeutic solutions, antibiotics, and radiopharmaceuticals, such as herceptin (herceptin), cisplatin (cissplatinum), fluorouracil (fluorouracil), leucovorin (leucovorin), paclitaxel (taxol), methoxan (methaxat), gemcitabine hydrochloride for injection (gemzar), cyclophosphamide (cyclophosphamide), cyclophosphamide (cytoxan), and cyclophosphamide injectate (neosar), or combinations of the above-listed medical solutions in liquid, solid, or gaseous form.
Wherein a hazardous medical liquid in liquid or powder form is contained in a vial (first container) and is usually prepared in a separate room by a dispensing person provided with protective clothing, a mask and a laminar flow safety cabinet, who transfers the hazardous medical liquid from the vial (first container) by means of a syringe provided with a cannula, i.e. a hollow injection needle, which is added to the corresponding solution.
Since the hazardous medical solution is toxic, direct physical contact with the hazardous medical solution or even exposure to minute amounts of hazardous medical solution vapor in the air can cause damage to the human body, increasing the risk of causing physical ailments such as skin cancer, leukemia, liver damage, deformities, miscarriage, and premature labor. In conventional hazardous liquid drug dispensing processes, locations susceptible to exposure of hazardous liquid drugs to air include containers, such as vials, bottles, syringes, and iv bags, containing hazardous liquid drugs that experience overpressure resulting in exposure of the hazardous liquid drug to contaminated air. Residue of the medical solution on the needle tip, vial or iv bag seal may also result in exposure to hazardous medical solutions. Therefore, it is desirable to provide a liquid medicine dispensing device which can prevent the hazardous liquid medicine from being easily exposed to the air or directly contacting with the human body during the dispensing process of the hazardous liquid medicine, so as to realize the airtight dispensing process of the hazardous liquid medicine.
