Sterile drug dispensing system and sterile drug dispensing method

A sterile drug dispensing method, comprising:

• preparing a sterile drug dispensing system comprising:
• an air source output device;
• a handle;
• a filter is disposed in the handle;
• and
• a drug dissolving device detachably mountable on the handle;
• wherein the drug dissolving device comprises
• a needle;
• a barrel;
• and
• a rubber stopper disposed inside the barrel;
• wherein the handle is connected to the air source output device through a power cord and an air pipe, for filtering air, and controlling the air source output device;
• wherein the air source output device is used to output and extract air, and
• the method further comprising the following steps:
• Step S6:
• inserting the needle of the drug dissolving device into a vial, controlling the rubber stopper in the drug dissolving device to move away from the needle, pumping a liquid medicine in the vial into the drug dissolving device, and pulling out the needle;
• Step S7:
• inserting the needle of the drug dissolving device into a new vial, the new vial being filled with a second liquid medicine or a powder medicine;
• when the new vial is filled with the second liquid medicine, controlling the rubber stopper in the drug dissolving device to move away from the needle, and pumping the second liquid medicine in the new vial into the drug dissolving device, and pulling out the needle;
• and when the new vial is filled with the powder medicine, controlling the rubber stopper to move toward the needle, pushing the liquid medicine into the new vial, and pulling out the needle after mixing;
• and
• Step S8:
• repeating Step S7 until the second liquid medicine or the powder medicine in the new vial is pumped into the drug dissolving device;
• reserving a certain distance between the rubber stopper and a front end of the barrel in the drug dissolving device to counter a negative pressure in the vial,
• before Step S6, the method further includes Step S5:
• Step S5:
• mounting the drug dissolving device on the handle;
• before Step S5, the method further includes the following steps:
• Step S1:
• the air source output device outputting a power air source to the handle, the power air source replacing a front end region of the handle with a clean and sterile environment after passing through the filter in the handle;
• Step S2:
• attaching the drug dissolving device to an inside of the front end of the handle and pushing backwards until a rear end of the drug dissolving device enters the sterile environment at the front end of the handle;
• and
• Step S3:
• mounting the drug dissolving device rearward on the handle while controlling the air source output device to stop providing the power air source to the handle.
