Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of aseptic dispensing, and in particular to a clean air host with a dispensing device storage bin and a pneumatic dispensing system. Background Art
[0002] Injection dispensing usually uses a manually operated dissolving device. The dissolving device on the market includes an outer coat and a movable rubber plug arranged in the outer coat. The front end of the outer coat is equipped with a needle, the rear end is provided with an opening, and the rear end of the movable rubber plug is provided with a core rod extending from the opening to the outside of the outer coat. During the dispensing process, a person first manually operates the core rod to drive the movable rubber plug to move forward in the outer coat to discharge the air between the front end of the movable rubber plug and the front end of the outer coat, and then operates the core rod to drive the movable rubber plug to move backward in the outer coat, so that the outer coat absorbs the drug solution through the needle. After the movable rubber plug moves forward to discharge the air between the front end of the movable rubber plug and the front end of the outer coat, the inner wall of the outer coat located behind the movable rubber plug is connected to the outside air through the rear end opening of the outer coat, so that bacteria in the air can easily enter from the rear end opening of the outer coat and then attach to the inner wall of the outer coat. Then the movable rubber plug moves backward to reset, so that the outer coat absorbs the drug solution. Then the inner wall of the outer coat that was originally connected to the outside air contacts the drug solution, causing the bacteria attached to the inner wall of the outer coat to contaminate the drug solution.
[0003] A pneumatic dispensing system is currently available, which includes a clean air main unit and a dispensing device for installing a dissolving device. The clean air main unit is connected to the rear end opening of the outer jacket of the dissolving device installed on the dispensing device via an air pipe. During the dispensing process, the clean air main unit blows sterile clean air through the air pipe to the rear end opening of the outer jacket of the dissolving device on the dispensing device, causing the movable rubber plug of the dissolving device to move forward under the action of air pressure, and expelling the air between the front end of the movable rubber plug and the front end of the outer jacket. At this time, bacteria in the air cannot enter through the rear end opening of the outer jacket and adhere to the inner wall of the outer jacket; after the air between the front end of the movable rubber plug and the front end of the outer jacket is expelled, the clean air main unit reversely inhales the air between the rear end opening of the outer jacket and the rear end of the movable rubber plug through the air pipe, so that a negative pressure is formed between the rear end opening of the outer jacket and the rear end of the movable rubber plug. The movable rubber plug then moves backward and resets under the action of the negative pressure, causing the outer jacket to absorb the drug solution through the needle. Since there are no bacteria attached to the inner wall of the outer jacket, the drug solution absorbed into the outer jacket will not be contaminated by bacteria. This pneumatic dispensing system can prevent bacterial contamination of the drug solution inhaled into the outer sleeve during the dispensing process. However, before dispensing begins, the dispenser is placed in the air for a long time. Bacteria in the air may enter and attach to the mounting part of the dispenser, resulting in the possibility of contamination of the drug solution when dispensing using the pneumatic dispensing system. Summary of the Invention

[0015] The present invention is further described in detail below in conjunction with specific embodiments.
[0016] Pneumatic dispensing system such as Figure 1As shown, it includes a dispensing device 1 and a clean air main unit 2 with a dispensing device storage compartment. The dispensing device 1 includes a mounting portion 11 for mounting the dissolving device and an air inlet end 12 for connecting to the clean air main unit 2. The mounting portion 11 is connected to the air inlet end 12. The mounting portion 11 serves as the handle of the dispensing device 1. In this embodiment, the dissolving device mounted on the dispensing device 1 includes an outer sleeve and a movable rubber plug disposed within the outer sleeve. The outer sleeve has a needle mounted at the front end and an opening at the rear end. The movable rubber plug can move back and forth within the outer sleeve.
[0017] The clean air host 2 includes a housing 11, in which an air source device and an air filter device are installed. An air outlet port 22 is provided on the housing 21. The air source device is connected to the air outlet port 22 via the air filter device, and the air outlet port 22 is connected to the air inlet end 12 of the dispenser 1 via an air pipe (not shown in the figure). The housing 1 is provided with a storage bin 23 for storing the dispenser 1. The storage bin 23 has a bin cover. A through hole 25 is provided between the bin cover of the storage bin 23 and the housing 1. The dispenser 1 specifically has its mounting portion 11 stored in the storage bin 23, and the air inlet end 12 is exposed outside the storage bin 23. When the bin cover of the storage bin 23 is closed, the through hole 25 blocks the portion between the mounting portion 11 and the air inlet end 12 of the dispenser 1. Figure 2 As shown, a sterilization device 24 is provided in the storage bin 23 , and the sterilization device 24 is specifically an ultraviolet lamp or an ozone disinfection device.
[0018] Before using the dispenser 1, the mounting portion 11 of the dispenser 1 can be placed in the storage bin 23 of the clean air host 2, with the air inlet end 12 exposed outside the storage bin 23. Then, the bin cover of the storage bin 23 is closed so that the through hole 25 is stuck in the area between the mounting portion 11 of the dispenser 1 and the air inlet end 12. Then, the mounting portion 11 of the dispenser 1 is sterilized using the sterilization equipment 24 in the storage bin 23. After sterilization, the mounting portion 11 of the dispenser 1 is stored in the storage bin 23 to prevent bacteria in the air from entering and adhering to the mounting portion 11 of the dispenser 1 and causing contamination.
[0019] When using the dispenser 1, first open the cover of the storage bin 23, take the dispenser 1 out of the storage bin 23, and then install the dissolver on the mounting portion 11 of the dispenser 1 so that the rear end opening of the dissolver jacket is connected to the air inlet end 12. Then the clean air host 2 can be started to make the air source device blow out air, and the air is output from the air outlet port 22 after passing through the air filter device. The clean air is transmitted from the air inlet end 12 of the dispenser 1 to the mounting part 11, and the movable plug of the drug dissolver on the mounting part 11 moves forward under the action of air pressure, and the air between the front end of the movable plug and the front end of the outer coat is discharged. At this time, the bacteria in the air cannot enter from the rear end opening of the outer coat and attach to the inner wall of the outer coat; after the air between the front end of the movable plug and the front end of the outer coat is discharged, the clean air host 2 reversely inhales the air between the rear end opening of the outer coat and the rear end of the movable plug through the trachea, so that a negative pressure is formed between the rear end opening of the outer coat and the rear end of the movable plug. The movable plug then moves backward and resets under the action of the negative pressure, causing the outer coat to absorb the drug solution through the needle. Since there are no bacteria attached to the inner wall of the outer coat, the drug solution inhaled into the outer coat will not be contaminated by bacteria.
[0020] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
