detailed description

The above-mentioned and other technical features and advantages of the present utility model will be described in more detail below in conjunction with the accompanying drawings.

Example 1

As shown in FIG. 1 , it is a schematic structural view of the main body of the drug dissolver according to Embodiment 1 of the present invention. As shown in FIG. 2 , it is a schematic structural view of the drug dissolving device of the aseptic drug dispensing system according to Embodiment 1 of the present utility model. An aseptic dispensing system provided in this embodiment includes a drug dissolver body 1 , a first connection portion 13 is provided at one end of the drug dissolver body 1 , and a second connection portion 14 is provided at the other end. The first connection part 13 and the first purification device 4 are connected by screw thread or buckle connection or claw hook connection or twist connection or magnetic force connection. The second connection part 14 is connected with the medicine fetching device 2 by thread connection, buckle connection, claw hook connection, turn buckle connection or magnetic force connection. The piston 3 is built in the drug dissolver body 1 . The piston 3 moves axially in the drug dissolver body 1 . The piston 3 divides the drug dissolver body 1 into a first cavity 11 and a second cavity 12 . The material used to make the piston 3 is silicone rubber with high temperature resistance and biosafety. The shape of the drug dissolver body 1 is a cylinder, an ellipse, a cuboid or a triangular prism.

The first purification device 4 communicates with the first air pump 9 through the joint 5. A gas pipeline 6 is also arranged inside the first purification device 4. One end of the gas pipeline 6 communicates with the joint 5, and the other end communicates with the second cavity 12. The gas pipe The road 6 is provided with a first air filter 7, the first air filter 7 is used to filter the gas from the first air pump 9, and the first air filter 7 makes the air from the first air pump 9 become sterile air.

A sealing ring 8 is provided at the connection between the first purification device 4 and the first connecting portion 13 . The cross-sectional area of the end of the gas pipeline 6 communicating with the drug dissolver body 1 is smaller than the cross-sectional area of the piston 3 , which has the advantage of preventing the piston 3 from detaching from the drug dissolver body 1 and entering the gas pipeline 6 .

The aseptic dispensing system provided in this embodiment also includes a clean laminar flow device 10, the clean laminar flow device 10 is set on the first purification device 4, an annular air outlet is arranged on the clean laminar flow device 10, and the clean laminar flow device 10 passes through the Air pipe 17 communicates with the second cleaning device 15, and the second air filter 16 is built in the second cleaning device 15, and the second air filter 16 is used to filter the gas from the second air pump 18, and the second air pump 18 communicates with the second air pump 18 through the pipeline. The two purification devices 15 are connected.

The working principle of this embodiment is:

Before dispensing starts, start the second air pump 18, and the second air pump 18 pumps air into the second purification device 15. After the air is filtered by the second air filter 16, it flows through the trachea 17 and the clean laminar flow device 10 in sequence. The sterile air is discharged through the annular air outlet on the clean laminar flow device 10, and the sterile air forms a positive pressure at the annular air outlet. The sterile air forming a positive pressure surrounds the drug dissolving device body 1 and the drug taking device 2 to form a gas-shielded laminar flow, which can prevent the drug dissolving device body 1 and the drug taking device 2 from contacting the air with bacteria. Enhanced dispensing security.

The drug dissolver body 1 is airtightly connected with the first purification device 4. After the connection, the first air pump 9 presses air into the gas pipeline 6. Since the gas pipeline 6 communicates with the second cavity 12, the second cavity The air pressure in the second chamber 12 rises, and when the air pressure in the second chamber 12 is higher than that in the first chamber 11, the high-pressure gas in the second chamber 12 pushes the piston to move toward the medicine fetcher 2. All the air in the first cavity 11 is exhausted. When all the air in the first cavity 11 is exhausted, the medicine fetcher 2 is inserted into the liquid medicine bottle, and then the air in the second cavity 12 is pumped out by the first air pump 9. When the gas is sucked out, when the pressure in the first cavity 11 is greater than the pressure in the second cavity 12 , the piston 3 moves toward the first purification device 4 to suck the liquid medicine into the first cavity 11 . Then remove the liquid medicine bottle, insert the medicine taker 2 into the freeze-dried powder medicine bottle, control the first air pump 9 to press air into the gas pipeline 6, when the air pressure in the second cavity 12 is higher than that in the first cavity 11, the high-pressure gas in the second cavity 12 pushes the piston to move in the direction close to the medicine taker 2, so that the medicinal solution in the first cavity 11 flows into the freeze-dried powder medicament bottle, and when the medicinal solution and the freeze-dried powder are fully After mixing, the gas in the second cavity 12 is sucked out by the first air pump 9, and when the pressure in the first cavity 11 is greater than the pressure in the second cavity 12, the piston 3 moves toward the direction close to the first purification device 4 , and further, extract the mixture of the freeze-dried powder and the liquid medicine into the first cavity 11 to complete the dispensing.

During the working process of the dispensing system, since the gas pipeline 6 is provided with the first air filter 7, the air flowing into the second cavity 12 is purified sterile air, preventing the inside of the drug dissolver body 1 from being polluted, so that The dispensing process is safer.

During the entire working process of the dispensing system, the second air pump 18 is always in working condition, so that the gas-shielded laminar flow always exists, so as to ensure that the medicine dissolving device body 1, the medicine taking device 2 and the medicine bottle are in a sterile environment.

The above descriptions are only preferred embodiments of the present utility model, and are only illustrative, not restrictive, of the present utility model. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the utility model, but all will fall within the protection scope of the utility model.
