A horizontally extending guide needle placement frame 15 is fixedly connected to the lower sliding sleeve 12. A horizontally extending normal saline bottle mouth fixing frame 14 is fixedly connected to the fixed ring seat 11. The axes of the medicine placement frame 16, the guide needle placement frame 15 and the normal saline bottle mouth fixing frame 14 coincide. The medicine placement frame 16 is used to place the medicine bottle 21 and the mouth of the medicine bottle 21 can extend out from the bottom of the medicine placement frame 16. The guide needle placement frame 15 is used to place the guide needle 20 and is provided with a hole for avoiding the needle tip of the guide needle 20. The normal saline bottle mouth fixing frame 14 is a U-shaped open structure for clamping the mouth of the normal saline bottle 19.

[0025] The guide needle 20 includes a needle seat at the center. The needle seat is in snap-fit with the guide needle placement frame 15. The needle seat is provided with a guide needle tip 23 and a gas guide needle tip 24 penetrating up and down. The upper end of the guide needle tip 23 extends out of the needle seat by a length slightly greater than the thickness of the cap of the medicine bottle 21. The lower end of the guide needle tip 23 extends out of the needle seat by a length greater than the thickness of the cap of the normal saline bottle 19.

The upper end of the gas guide needle tip 24 extends out of the needle seat by a length slightly greater than the thickness of the cap of the normal saline bottle 19. Both ends of the guide needle tip 23 and the gas guide needle tip 24 are pointed.

[0026] The guide needle 20 is a disposable product with a sterile package.

[0027] A vertical rod extending downward is provided on the cantilever of the electric lifting rod 6 connected to the lifting and pressure regulating seat 7, and a liquid level sensor 22 is installed at the bottom of the vertical rod; the liquid level sensor 22 is aligned with the bottom of the medicine placement frame 16 for monitoring whether the medicine in the medicine bottle 21 is exhausted; the bottom of the medicine placement frame 16 is a hollow structure to avoid affecting the normal operation of the liquid level sensor 22, and the liquid level sensor 22 is bidirectionally signal-connected to the control module.

[0028] Working principle of this embodiment:

[0029] When this embodiment is in use, the staff places the medicine bottle 21 and the normal saline bottle 19 in the same medicine dispensing unit 8 according to the corresponding relationship. The medicine bottle 21 is placed in the medicine placement frame 16, and its bottle mouth extends out from the bottom. The bottle mouth of the normal saline bottle 19 is clamped and fixed by a U-shaped normal saline bottle mouth fixing frame 14. The guide needle 20 is installed in the guide needle placement frame 15, and the needle tip of the guide needle 20 is aligned with the bottle mouths of the medicine bottle 21 and the normal saline bottle 19.

[0030] Then, the motor 3 drives the turntable 5 to rotate through gear transmission, and each medicine dispensing unit 8 is rotated to the working position one by one. Since the motor 3 is a servo motor, it can accurately control the rotation angle of the turntable 5 to ensure that the medicine dispensing unit 8 is accurately in place. After the medicine dispensing unit 8 is in place, the electric lifting rod 6 drives the lifting and pressure regulating seat 7 to descend, pushing the guide needle 20 to insert into the bottle mouths of the medicine bottle 21 and the normal saline bottle 19. The two ends of the needle tip of the guide needle 20 penetrate the bottle caps of the medicine bottle 21 and the normal saline bottle 19 respectively. Through the guide needle 20, the medicine flows from the medicine bottle 21 into the normal saline bottle 19. The liquid level sensor 22 monitors the liquid level of the medicine in the medicine bottle 21 in real time. When the medicine is exhausted, the sensor feeds back the signal to the control module, and the medicine dispensing of this medicine dispensing unit is completed.

[0031] When the medicine dispensing operation is completed and the electric lifting rod 6 drives the lifting and pressure regulating seat 7 to rise, the pressure of the lifting and pressure regulating seat 7 on the upper sliding sleeve 13 is released. At this time, the elastic restoring forces of the upper spring 18 and the lower spring 17 start to take effect: the upper spring 18 pushes the upper sliding sleeve 13 upward to restore it to the initial position, and at the same time drives the medicine placement frame 16 to reset. The lower spring 17 pushes the lower sliding sleeve 12 upward to restore it to the initial position, and at the same time drives the guide needle placement frame 15 to reset. Through the combined action of the upper spring 18 and the lower spring 17, the lower sliding sleeve 12 and the upper sliding sleeve 13 return to the initial position, the guide needle 20 withdraws from the normal saline bottle 19 and stays on the medicine bottle 21, and the device returns to the initial state. When all the medicine dispensing units 8 complete the medicine dispensing at one time, the guide needle 20, the medicine bottle 21 and the normal saline bottle 19 can be taken out from the medicine dispensing unit 8. This embodiment effectively solves the problems of low efficiency, inaccurate dosage and cumbersome operation in traditional manual medicine dispensing through automated, precise and aseptic designs.

[0032] In this embodiment, the guiding needle 20 is a disposable item with a sterile package, which can avoid contaminating the medicine due to repeated use.

[0033] In this embodiment, the pointed designs of the guiding needle tip 23 and the air guiding needle tip 24 on the guiding needle 20 ensure smooth penetration of the bottle cap. At the same time, the length design of the air guiding needle tip 24 ensures the air pressure balance in the medicine bottle 21, avoiding the generation of negative pressure in the medicine bottle 21. Under the state without negative pressure, the medicine in the medicine bottle 21 flows into the physiological saline bottle 19 under the action of gravity. Through a simple structure in this embodiment, the transfer of the medicine in the medicine bottle to the physiological saline bottle can be realized.

[0034] Embodiment 2: Please refer to Figures 1 to 8 , a portable clinical pharmacy dispensing device, which is different from Embodiment 1 in that the control module of the box body 1 is provided with a programmable module, and the programmable module can be programmed through the PC side. The liquid level sensor 22 can monitor the remaining dosage of medicine in the medicine bottle 21. An identification module is provided on the side wall of the electric lifting rod 6, and the identification module is used to identify the physiological saline bottle 19 and the medicine bottle 21 in the dispensing unit 8. The identification module is signal-connected to the control module.

[0035] The working principle of this embodiment:

[0036] Before use, the staff can program the programmable module of the control module in the box body 1 through the PC side, and set the dispensing ratio, dispensing sequence and other relevant parameters of each medicine bottle 21 and physiological saline bottle 19. These settings will guide the subsequent automatic dispensing process. When the dispensing unit 8 is rotated to the working position by the turntable 5, the identification module on the side wall of the electric lifting rod 6 starts to work. The identification module can identify the types and specifications of the medicine bottle 21 and the physiological saline bottle 19 by reading barcodes, two-dimensional codes or other identifiers on them. After the identification is completed, the identification module sends the information to the control module. The control module judges whether the medicine bottle 21 and the physiological saline bottle 19 in the current dispensing unit 8 meet the dispensing requirements set by the programming according to the preset programming instructions.

[0037] If the medicine bottle 21 and the physiological saline bottle 19 in the dispensing unit 8 meet the programming requirements, the control module will instruct the electric lifting rod 6 to drive the lifting and pressing seat 7 to descend, so that the guiding needle 20 penetrates the bottle caps of the medicine bottle 21 and the physiological saline bottle 19, and the dispensing process starts. During the dispensing process, the liquid level sensor 22 continuously monitors the liquid level of the medicine in the medicine bottle 21. When the medicine is exhausted or reaches the preset dosage, the liquid level sensor 22 feeds back the signal to the control module. The control module accurately controls the lifting of the electric lifting rod 6 according to the feedback of the liquid level sensor 22 and the programmed dispensing ratio, so as to control the insertion and extraction time of the guiding needle 20 between the medicine bottle 21 and the physiological saline bottle 19, and ensure the accuracy of the dispensing amount.

[0038] If the recognition module detects any medicine bottles 21 or normal saline bottles 19 that do not meet the preset requirements during the medicine dispensing process, the control module will pause the medicine dispensing process and issue an alarm to prompt the staff to intervene.

[0039] Through the introduction of the programmable module and the recognition module in this embodiment, a more intelligent and automated medicine dispensing process is achieved, improving the accuracy and efficiency of medicine dispensing, while reducing the risk of human operation errors.
