[0033] In this embodiment, a puncture mechanism 1 is designed, wherein the puncture mechanism 1 includes a pressing block 11, and a fixing block 12, a fixing rod 13 and a ejector pin 14 are connected to the bottom end of the inner wall of the pressing block 11, which can be used to puncture the capsule body 24 so that the medicine inside the capsule body 24 can be discharged, and a connecting block 16 is connected to the inner wall of the lower end of the pressing block 11, and a plurality of card blocks 17 are connected to the bottom end of the outer wall of the connecting block 16, which can be connected to the nozzle mechanism 3 for limiting position, and a spring 18 is provided on one side of the inner wall of the connecting block 16, wherein the upper end of the spring 18 is connected to the top of the inner wall of the pressing block 11, and the lower end of the spring 18 is connected to the outer wall of the upper end of the medicine releasing mechanism 2, and the pressing block is pressed. 11 enables the ejector pin 14 to play a reset role after puncturing the communicating hole 25, and its upward elastic force enables the card block 17 to play a better limiting role when connected to the nozzle mechanism 3. Since the existing device, after puncturing the communicating hole 25, is squeezed by the ejector pin 14, the communicating hole 25 will be tightly attached to the inner wall of the medicine tray block 21, making it difficult to remove. At this time, a plurality of barb blocks 15 can be arranged in a circular array on the outer wall of the ejector pin 14, and the barb blocks 15 are directed upward. Therefore, when taking out the ejector pin 14, the barb blocks 15 provided on the outer wall of the ejector pin 14 can exert an upward force on the capsule body 24 after puncture, thereby taking out the capsule body 24;
[0034] A medicine releasing mechanism 2 is designed, wherein the medicine releasing mechanism 2 includes a medicine tray block 21, a limiting ring 23 is connected to the upper end of the medicine tray block 21, a hole is opened in the middle of the limiting ring 23, and is correspondingly connected to the fixing rod 13 and the ejector pin 14, which can play a limiting role, and a plurality of limiting blocks 22 are arranged in a circular array on the outer wall of the medicine tray block 21, and the limiting blocks 22 can be connected to the suction nozzle mechanism 3, and the inner wall of the medicine tray block 21 is connected to the capsule body 24, so the medicine tray block 21 is connected to the suction nozzle mechanism 3 to play a role in supporting the medicine tray block 21 and the capsule body 24, and a connecting hole 25 is opened at the bottom of the medicine tray block 21, and the connecting hole 25 is correspondingly connected to the capsule body 24, so that when the ejector pin 14 punctures the capsule body 24, the medicine powder inside the capsule body 24 can be transported to the suction nozzle mechanism 3 through the connecting hole 25, thereby performing a drug administration operation.
[0035] Example 2
[0036] like Figure 1-2 and Figure 6 As shown, the nozzle mechanism 3 includes a tube body 31, a nozzle body 32 is fixedly connected to the lower end of the tube body 31, a mounting groove 33 is opened at the upper end of the tube body 31, a limiting block 22 connected to the outer wall of the medicine holder block 21 is movably connected with the mounting groove 33 opened on the outer wall of the upper end of the tube body 31, a limiting groove 34 is opened on the inner wall of the upper end of the tube body 31, and a clamping block 17 connected to the bottom end of the outer wall of the connecting block 16 is movably connected with the limiting groove 34 opened on the upper end of the inner wall of the tube body 31.
[0037] In this embodiment, a suction nozzle mechanism 3 is designed, wherein the suction nozzle mechanism 3 includes a tube body 31, and a suction nozzle body 32 is connected to the bottom end of the tube body 31, and the medicine powder inside the tube body 31 can be sucked into the mouth through the suction nozzle body 32, and a mounting groove 33 is provided at the upper end of the tube body 31, and the inner wall of the mounting groove 33 can be connected to the limit block 22 accordingly, and a limit groove 34 is provided at the upper end of the inner wall of the tube body 31, and the limit groove 34 can be connected to the block 17 accordingly, so that the upper end of the tube body 31 respectively supports and limits the medicine tray block 21 and the connecting block 16, and the connecting block 16 is connected to the limit groove 34 through the block 17, so as to limit the medicine tray block 21 to prevent the medicine tray block 21 from shaking, thereby making it impossible to perform the puncture operation.
[0038] Working principle:
[0039] like Figure 1-6 As shown, the medicine tray block 21 is connected to the mounting groove 33 at the upper end of the tube body 31 through the limiting block 22. At this time, the capsule body 24 is placed in the inner wall of the medicine tray block 21. Next, the connecting block 16 connected to the lower end of the pressing block 11 is inserted into the tube body 31. At this time, it is necessary to first align the block 17 at the bottom end of the outer wall of the connecting block 16 with the mounting groove 33. When a certain position is reached, the connecting block 16 is rotated so that the block 17 connected to the outer wall of the lower end is connected to the limiting groove 34 at the upper end of the inner wall of the tube body 31. The connecting block 16 is connected to the upper end of the medicine tray block 21, and through the action of the spring 18, an upward force is applied to the pressing block 11, thereby driving the block 17 to generate an upward force in the limiting groove 34, which plays a limiting role. At this time, the pressing block 11 is pressed to move the pressing block 11 downward, and drives the fixing block 12 and the fixing rod 13 connected to the lower end to perform a puncture operation on the capsule body 24. When the capsule body 24 is punctured, the medicine powder inside it enters the tube body 31 through the connecting hole 25. At this time, the medicine powder in the tube body 31 is sucked out through the suction nozzle body 32, and the medication operation can be completed. The punctured capsule body 24 will be limited by the barb block 15 on the outer wall of the ejector pin 14. The connection operation of the puncture mechanism 1 and the suction nozzle mechanism 3 is reversed, and the capsule body 24 can be taken out of the medicine tray block 21, so as to facilitate the cleaning of the medicine tray block 21 and improve the use efficiency of the device.
