Description

Technical Field

[0001] The utility model relates to the technical field of injection dispensing, in particular to an electric dispensing device with a retractable driving component and an electric dispensing system. Background Art

[0002] At present, injection dispensing usually uses a manually operated drug dissolver. The drug dissolver on the market includes a barrel and a movable rubber plug arranged in the barrel, a needle is installed at the front end of the barrel, an opening is opened at the rear end, and a core rod extending from the opening to the outside of the barrel is provided at the rear end of the movable rubber plug. During the dispensing process, the core rod is manually operated to drive the movable rubber plug to move forward in the barrel to discharge the air between the front end of the movable rubber plug and the front end of the barrel, and then the core rod is operated to drive the movable rubber plug to move backward in the barrel, so that the barrel absorbs the drug solution through the needle. Manually operated drug dissolvers are prone to fatigue and mistakes when repeated dispensing operations are performed multiple times.

[0003] There is an electric medicine dispensing device, which is provided with a mounting portion for mounting a medicine dissolving device and a driving portion arranged behind the mounting portion. A driving component is arranged in the driving portion. The front end of the driving component extends into the mounting portion, and drives the movable rubber plug of the medicine dissolving device to move forward and backward to perform medicine dispensing operations. There is no need to manually operate the medicine dissolving device to perform medicine dispensing operations, thereby reducing the possibility of manual errors. In order to avoid damage to the medicine dissolving device caused by excessive forward and backward movement of the movable rubber plug by the driving component, the electric medicine dispensing device is provided with a front limit detector and a rear limit detector. During the medicine dispensing process, the front limit detector and the rear limit detector are used to limit the front end of the driving component to move forward and backward in the mounting portion, so that the movable rubber plug of the medicine dissolving device is limited and does not move forward and backward excessively, thereby avoiding damage to the medicine dissolving device. Since the front end of the driving component is limited to move forward and backward in the mounting portion, and the front end of the driving component will block the mounting portion, it is not convenient to clean the mounting portion. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hardware structure of an electric medicine dispensing device for software engineers, so that after the software engineers program the hardware structure, the electric medicine dispensing device can facilitate cleaning of the mounting portion for mounting the medicine dissolving device under the premise of avoiding excessive forward and backward movement of the movable rubber plug of the medicine dissolving device.

[0005] In order to solve the above technical problems, the utility model provides an electric dispenser with a retractable drive component, comprising a mounting portion for mounting a drug dissolving device and a drive portion arranged at the rear of the mounting portion, wherein a drive component and a drive motor for driving the drive component are arranged in the drive portion, wherein the drive component comprises a screw rod mounted on the drive motor and a nut slider driven by the screw rod to move forward and backward, wherein the front end of the nut slider extends into the mounting portion to drive the movable rubber plug of the drug dissolving device to move forward and backward to perform a dispensing operation, and comprises a front limit detector, a rear limit detector and a control main board, wherein the control main board is electrically connected to the front limit detector, the rear limit detector and the drive motor respectively; a stopper is provided on the nut slider which moves with it, the detection point of the front limit detector is located on the forward moving path of the stopper, and the detection point of the rear limit detector is located on the backward moving path of the stopper; an opening is opened at the front end of the drive portion for the front end of the nut slider to retreat into the drive portion, and the control main board is electrically connected with a function button for controlling the start and stop of the rear limit detector.

[0006] Furthermore, the front limit detector and the rear limit detector are optical couplers, which include a light emitter and a light receiver that are arranged opposite to each other, and the detection point is located between the light emitter and the light receiver.

[0007] Furthermore, the front limit detector and the rear limit detector are installed on a control main board.

[0008] Furthermore, the front limit detector, the rear limit detector and the control main board are installed in the driving part.

[0009] Furthermore, a clamping groove is provided at the front end of the nut slider for the core rod of the drug dissolver to be clamped in, and the nut slider drives the core rod of the drug dissolver to drive the movable rubber plug to move forward and backward through its clamping groove.

[0010] Furthermore, the driving unit housing serves as a handle of the medicine dispenser.

[0011] The utility model also provides an electric medicine dispensing system, comprising a medicine dissolving device and the electric medicine dispensing device as described above, wherein the medicine dissolving device is mounted on a mounting portion of the electric medicine dispensing device.

[0012] The utility model has the following beneficial effects: after the software engineer programs the control mainboard of the electric medicine dispensing device, in the process of using the electric medicine dispensing device to dispense medicine, the control mainboard controls the driving motor to drive the movable rubber plug of the medicine dissolving device to move forward and backward through the driving component to perform the medicine dispensing operation, and in this process, the nut slider of the driving component drives the block to move forward and backward synchronously. Since the detection point of the front limit detector is located on the forward moving path of the block, when the block moves forward until it passes the detection point of the front limit detector, the control mainboard detects that the block passes through the front limit detector, and accordingly controls the driving motor to stop driving the nut slider to continue to move forward, so that the nut slider drives the movable rubber plug to move forward excessively and cause damage to the medicine dissolving device, and since the detection point of the rear limit detector is located on the backward moving path of the block, when the block moves backward until it passes the detection point of the rear limit detector, the control mainboard detects that the block passes through the rear limit detector, and accordingly controls the driving motor to stop driving the nut slider to continue to move backward, so that the nut slider drives the movable rubber plug to move backward excessively and cause damage to the medicine dissolving device. After the medicine dispensing is completed, if it is necessary to clean the installation part for installing the dissolver, the user can first remove the dissolver, then press the function button to turn off the rear limit detector, and then control the main board to control the drive motor to drive the nut slider to move backward. Since the rear limit detector is turned off, the nut slider can drive the blocker to move backward and pass the rear limit detector until the nut slider retreats into the drive part through the opening at the front end of the drive part, and no longer blocks the installation part, which is convenient for the user to clean the installation part.

[0018] The present invention is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1As shown, the electric medicine dispenser includes a mounting portion 1 for mounting a medicine dissolving device 3 and a driving portion 2 arranged at the rear of the mounting portion 1. After the medicine dissolving device 3 is mounted on the mounting portion 1, it is fixed, and the front end of the medicine dissolving device 3 extends forward to the outside of the front end of the mounting portion 1. The outer shell of the driving portion 2 serves as a handle of the electric medicine dispenser, and the user can hold the driving portion 2 to perform the medicine dispensing operation.

[0020] like Figure 2 As shown, the driving part 2 is provided with a control main board 10, a driving assembly and a driving motor 7 for driving the driving assembly, wherein the control main board 10 is a PCB circuit board with a microprocessor integrated thereon, and the control main board 10 is electrically connected to the driving motor 7. The driving assembly includes a screw rod 8 mounted on the driving motor 7 and a nut slider 9 driven by the screw rod 8 to move forward and backward, the front end of the nut slider 9 extends forward to the outside of the driving part 2 and extends into the mounting part 1 to form a snap-in groove 91 with a notch facing upward, and the front end of the driving part 2 is provided with an opening for the snap-in groove 91 at the front end of the nut slider 9 to return to the driving part 2. A movable rubber plug 31 is provided in the cylinder of the dissolver 3, and a core rod 32 for pushing and pulling the movable rubber plug 31 to move forward and backward is provided at the rear end of the movable rubber plug 31. After the dissolver 3 is installed on the mounting part 1, the core rod 32 of the dissolver 3 is snapped into the snap-in groove 91. The driving motor 7 can drive the screw rod 8 of the driving assembly to rotate so that the nut slider 9 moves forward and backward along the screw rod 8. The nut slider 9 drives the core rod 32 of the dissolving device 3 to drive the movable rubber plug 31 to move forward and backward through the clamping groove 91 at its front end. A key circuit board 17 is provided in the mounting portion 1. The key circuit board 17 is provided with a control button 16 electrically connected to it. The key circuit board 17 is electrically connected to the control main board 10, so that the control button 16 is electrically connected to the control main board 10 through the key circuit board 17. The user can send forward movement instructions and backward movement instructions to the control main board 10 through the control button 16.

[0021] like Figure 3 As shown, the control main board 10 is provided with a front limit detector 12 and a rear limit detector 13 electrically connected thereto. Both the front limit detector 12 and the rear limit detector 13 are optical couplers, which include a light emitter and a light receiver arranged relatively to each other. The detection point of the optical coupler is located between the light emitter and the light receiver. A stopper 14 is provided at the bottom of the nut slider 9. The nut slider 9 drives the movable rubber plug 31 of the dissolver 3 to move forward and backward, thereby driving the stopper 14 to move forward and backward synchronously along the screw rod 8. The detection point of the front limit detector 12 is located on the forward movement path of the stopper 14, specifically below the front end of the screw rod 8; the detection point of the rear limit detector 13 is located on the backward movement path of the stopper 14, specifically below the rear end of the screw rod 8.

[0022] When using the electric medicine dispensing device to dispense medicine, the medicine dissolving device 3 is first mounted on the mounting portion 1 so that the core rod 32 of the medicine dissolving device 3 is inserted into the clamping groove 91 , so that the electric medicine dispensing device and the medicine dissolving device 3 form an electric medicine dispensing system. Then the user can push the control button 16 forward to send a forward movement instruction to the control main board 10. The control main board 10 controls the drive motor 7 to drive the screw rod 8 to rotate forward, so that the nut slider 9 moves forward along the screw rod 8. The nut slider 9 drives the core rod 32 of the dissolver 3 through the clamping groove 91 at its front end to drive the movable plug 31 to move forward and discharge the air between the front end of the movable plug 31 of the dissolver 3 and the front end of the cylinder. In this process, the nut slider 9 drives the stopper 14 to move forward synchronously. Since the detection point of the front limit detector 12 is located on the forward movement path of the stopper 14, when the stopper 14 moves forward until it passes the detection point of the front limit detector 12, the control main board 10 detects the passage of the stopper 14 through the front limit detector 12, and accordingly controls the drive motor 7 to stop driving the nut slider 9 to continue to move forward. In this way, it can be avoided that the nut slider 9 drives the movable plug 31 to move forward excessively and cause damage to the dissolver 3. Then the user can push the control button 16 backward to send a backward movement instruction to the control main board 10, and the control main board 10 controls the driving motor 7 to drive the screw rod 8 to rotate in the opposite direction, so that the nut slider 9 moves backward along the screw rod 8, and the nut slider 9 drives the core rod 32 of the dissolver 3 through the clamping groove 91 at its front end to drive the movable plug 31 to move backward, so that the dissolver 3 inhales the drug solution. In this process, the nut slider 9 drives the baffle 14 to move backward synchronously. Since the detection point of the rear limit detector 13 is located on the backward movement path of the baffle 14, when the baffle 14 moves backward until it passes the detection point of the rear limit detector 13, the control main board 10 detects the passage of the baffle 14 through the rear limit detector 13, and accordingly controls the driving motor 7 to stop driving the nut slider 9 to continue to move backward, thereby avoiding the nut slider 9 driving the movable plug 31 to move backward excessively and causing damage to the dissolver 3.

[0023] In this embodiment, the key circuit board 17 is also provided with a function key 15 electrically connected thereto, and the function key 15 is electrically connected to the control main board 10 through the key circuit board 17, and the user can send a command to control the start and stop of the rear limit detector 13 to the control main board 10 through the function key 15. After the above-mentioned dispensing operation is completed, if it is necessary to clean the mounting portion 1 for mounting the dissolving device 3 on the electric dispensing device, the dissolving device 3 is first removed, and then the function key 15 is pressed to turn off the rear limit detector 13, and then the control key 16 is pushed back to send a backward movement command to the control main board 10, and then the control main board 10 controls the driving motor 7 to drive the screw rod 8 to rotate in the opposite direction, so that the nut slider 9 moves backward along the screw rod 8. At this time, since the rear limit detector 13 has been turned off, the nut slider 9 can drive the stopper 14 to move backward over the rear limit detector 13, until the nut slider 9 returns to the driving portion 2 through the opening at the front end of the driving portion 2, and no longer blocks the mounting portion 1, so that the user can clean the mounting portion 1. After the user finishes cleaning the mounting part 1, the user can push the control button 16 forward to send a forward movement instruction to the control main board 10, and the control main board 10 controls the drive motor 7 to drive the screw rod 8 to rotate forward, so that the nut slider 9 moves forward along the screw rod 8 until the nut slider 9 extends from the opening at the front end of the drive part 2 into the mounting part 1, and then press the function button 15 to start the rear limit detector 13, preparing for the next dispensing operation.

[0024] like Figure 4 As shown, a through hole 92 leading to the interior of the driving part 2 is formed at the front end of the nut slider 9, and the through hole 92 communicates with the space between the mounting part 1 and the interior of the driving part 2. Therefore, when cleaning the mounting part 1, the user can directly insert the cleaning tool into the driving part 2 through the through hole 92 to clean the driving component without disassembling the driving part 2, which is more convenient.

[0025] In this embodiment, a clean air duct 4 for transmitting clean air is provided in the driving part 2. The front end of the clean air duct 4 is connected to the mounting part 1, and the rear end is connected to the air pipe 6 via the connecting pipe assembly 5, and is connected to an external clean air host (not shown in the figure) through the air pipe 6. The clean air host has an air compressor and an air filter assembly. The air compressor blows out clean air through the air filter assembly. The clean air is blown into the mounting part 1 in sequence through the air pipe 6, the connecting pipe assembly 5, and the clean air duct 4, and the bacteria on the rear end of the dissolving device 3 are blown away, thereby forming a clean air cavity in the mounting part 1. In this way, bacteria in the air cannot enter the mounting part 1 and adhere to the inner wall of the cylinder of the dissolving device 3. Figure 5As shown, the driving part 2 is provided with an annular clamping part 21, and the outer edge of the annular clamping part 21 is provided with a clamping groove 22. The outer shell of the pipe assembly 5 is sleeved on the annular clamping part 21 and is sunk into the clamping groove 22, so that the pipe assembly 5 can rotate relative to the driving part 2 along the clamping groove 22. The pipe assembly 5 is provided with a first air guide 51 and a second air guide 52 that are mutually docked and can rotate relative to each other around the docking point. The first air guide 51 and the second air guide 52 are hollow inside to form an air guide channel. The first air guide 51 and the second air guide 52 are docked with each other, which means that the air guide channels of the two are aligned and sealed with each other without being connected together, so that the two can rotate relative to each other around the docking point. The first air guide 51 is connected to the air pipe 6, and the second air guide 52 extends into the driving part 2 to connect to the rear end of the clean air duct 4. During the relative rotation of the pipe assembly 5 and the driving part 2, the first air guide 51 and the second air guide 52 can maintain the air connection between the air pipe 6 and the clean air duct 4. The electric dispenser is provided with a signal line 11 electrically connected to the control main board 10. The signal line 11 extends from the drive unit 2 to the pipe assembly 5, surrounds the first air guide 51 and the second air guide 52, and then passes through the wall of the air pipe 6 to connect to the external clean air host, so that the control main board 10 is connected to the external air host through the signal line 11. In the above-mentioned dispensing process, the clean air host is connected to the electric dispenser through the air pipe 6 and the signal line 11, and together with the electric dispenser and the dissolving device 3, forms an electric dispensing system. The user holds the electric dispenser and changes the direction so that the needle of the dissolving device 3 is downward to inhale the drug solution from the medicine bottle for dispensing operation. In this process, since the pipe assembly 5 and the drive unit 2 can rotate relatively, during the period when the electric dispenser changes its direction, the pipe assembly 5 can be adaptively rotated so that the air pipe 6 does not rotate with the drive unit 2, so that the air pipe 6 is reduced in twisting and avoids damage.

[0026] The above is only an implementation method of the 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 invention, which still fall within the scope of patent protection.
