Description
Technical Field
The utility model relates to an aseptic automatic medicine dispenser.
Background
Clinical intravenous administration, mixing and blending work is heavy when medical personnel dispense medicines, the current clinical intravenous administration is mainly powder injection or freeze-dried powder, and the powder injection or freeze-dried powder is packaged by a penicillin bottle, and the dispensing mode is manual mixing and blending and various dispensing devices.
The conventional steps of manual mixing and blending are as follows: (1) puncturing a solvent infusion bottle rubber plug by using an injector, sucking corresponding dosage of solvent injection from a solvent bottle according to the dosage of the medicine, (2) then respectively puncturing a penicillin bottle rubber plug, inputting a proper amount of the solvent injection into the penicillin bottle, (3) forcibly shaking the penicillin bottle to fully dissolve the powder in the penicillin bottle, (4) respectively puncturing the penicillin bottle by using the injector again, sucking the dissolved liquid medicine back into the injector, and (5) in the process of sucking back, withdrawing the needle for several times, and then completely sucking the liquid medicine in the penicillin bottle. (6) The injector punctures the menstruum infusion bottle again, and the liquid medicine sucked back is re-injected into the infusion bottle again. As stated above, it can be seen that the medical staff is cumbersome to operate, and cannot perform strict aseptic operation specifications, and the open dispensing environment, repeated puncturing, pumping and back-sucking of the liquid medicine will increase the probability of the liquid medicine being contaminated by microorganisms in the air. More importantly, in the conventional dispensing mode, the infusion bottle cap rubber plug and the penicillin bottle rubber plug are repeatedly punctured for multiple times, the dropped tiny particle impurities of the rubber plugs can be brought into the liquid medicine to cause particle pollution, the liquid medicine polluted by the particles can cause serious harm to a human body along with the blood circulation of the human body, for example, red blood cells and the like are easy to agglomerate on the particles to form thrombus to block blood vessels, enter pulmonary capillaries to influence the lung function, cause thrombocytopenia and anaphylactic reaction, and stimulate tissues to generate inflammation to form lumps and the like. In addition, chemotherapy drugs, cytotoxic drugs, and drugs having genetic toxicity, carcinogenicity, teratogenicity, or a growth-impairing effect, and toxicity to organs and tissues, etc., may cause toxic or corrosive damage to medical workers upon leakage.
Dispensers or dispensing devices appearing on the market have the following characteristics: the medicine dispensing device is used for injecting a solvent in an infusion bottle into a penicillin bottle, an air hole needs to be reserved on the medicine dispensing device, the whole medicine dispensing process is directly communicated with the outside, and even if a filtering membrane is additionally arranged, the medicine liquid cannot be blocked from contacting the outside. More importantly, when the solvent of the infusion bottle is injected into the penicillin bottle, the medical staff is required to forcibly extrude the plastic infusion bottle, the gas in the infusion bottle and the penicillin bottle is discharged through the air holes in the medicine dispenser, after the hands are loosened, the external air is sucked back into the penicillin bottle and the infusion bottle due to the back suction effect of the plastic infusion bottle, and the medicine and the infusion in the penicillin bottle and the infusion bottle are processed under the aseptic condition, so that the product is an aseptic product, and the device can bring a large amount of microorganisms in the external air into the bottle to seriously pollute the aseptic powder injection and the aseptic large infusion. In addition, each bottle of infusion needs medical staff to forcibly squeeze the infusion bottle, the physical strength is heavy, and if the infusion bottle is packaged by hard materials such as a glass bottle, the infusion bottle cannot be squeezed, so that the device cannot be really applied to clinic and is subject to elimination.
