The upper arm 211 is connected to a lower arm medicine storage cylinder 213 through a joint portion 212. A medicine storage drawer 214 is slidably connected inside the lower arm medicine storage cylinder 213. A control structure for automatically extending the medicine storage drawer 214 is also provided inside the joint portion 212.

[0045] Multiple partitions 215 provided in the inner cavity of the medicine storage drawer 214 divide the inner cavity into multiple compartments for storing drugs for different patients in a classified manner. One end of the bottom of the medicine storage drawer 214 is threadedly connected with a limit screw 218 that penetrates through the bottom of the lower arm medicine storage cylinder 213 to limit the complete extraction of the medicine storage drawer 214. A limit groove 219 adapted to the limit screw 218 is provided at the bottom of the lower arm medicine storage cylinder 213.

[0046] The control structure includes a servo motor 216 fixedly connected inside the joint portion 212.

The lead screw 2110 is meshed and driven with the output shaft of the servo motor 216 through a gear set 217. The servo motor 216 controls the extension length of the medicine storage drawer 214 by driving the lead screw 2110 to rotate. Each time, it extends by the length of one grid to expose the drugs of one patient, ensuring that patients can only get their own drugs and guaranteeing the safety of the drugs. When taking or putting drugs, first, medical staff need to input their job numbers. After verification, the medicine storage drawer 214 can be opened to put in drugs; at the patient end, after verifying the patient's QR code, the corresponding drugs can be opened and taken out.

[0047] In this embodiment, to achieve the function of shaking the liquid medicine of the robot, the shaking structure 29 includes a shaking box 291 and an electric push rod 292 embedded and installed at the rear end of the joint part 212. A sponge lining 293 for placing the liquid medicine bottle is arranged inside the shaking box 291. The elastic setting of the sponge lining 293 can press the medicine bottle tightly to prevent it from shaking. The sponge lining 293 is provided with a plurality of connected cylindrical grooves, and a plurality of medicine bottles or medicine bags are inserted at the same time. A connecting sleeve 294 with a fastening bolt is fixed at the front end of the shaking box 291. The connecting sleeve 294 is located in the middle and upper layer on the side of the shaking box 291, so that when the shaking box 291 drives the medicine bottle to swing, there is a downward centrifugal force to prevent the medicine bottle from being thrown out from above. A torsion sleeve 295 is sleeved on the output end of the electric push rod 292, and the torsion sleeve 295 is rotatably connected to the rear end of the joint part 212. The rear end of the torsion sleeve 295 can be inserted into the connecting sleeve 294 and locked by a fastening bolt. This connection method is convenient for removing the shaking box 291. A prism shaft 296 adapted to be inserted and connected to the inside of the connecting sleeve 294 is further provided at the rear end of the torsion sleeve 295. Spiral torsion chamber grooves 297 are formed on opposite sides of the inner wall of the connecting sleeve 294, and round blocks 298 slidably adapted to the chamber grooves 297 are arranged on both sides of the output end of the electric push rod 292. The electric push rod 292 realizes the forward and reverse rotation of the torsion sleeve 295 by pushing and pulling the chamber grooves 297 with the round blocks 298, and then drives the shaking box 291 to rotate forward and backward. After the nurse configures the intravenous injection liquid medicine in the medicine bottle and medicine bag, it is put into the sponge lining 293 and then the swinging and shaking function is started to reduce the workload of the medical staff in intravenous injection liquid preparation.

[0048] Figure 10 The second implementation manner is shown. The main difference from the first implementation manner is that a central control host, a charging power supply and a memory are installed inside the lower limb part 3. The charging power supply is connected to the central control host to supply power to the intelligent nursing robot. The central control host controls the camera to take pictures for monitoring the patient taking medicine. The central control host is connected to the memory to store patient and medicine data. The central control host is connected to the touch display screen to display images and receive operation information on the touch display screen.

[0049] The central control host is equipped with an AI intelligent question-and-answer module, a walking control unit, a vital sign measurement unit, an extended rehabilitation management function, a medicine management and distribution unit, and a medicine-taking supervision module. The AI intelligent question-and-answer module completes answers by combining the commonly asked popular science questions and answers entered in the memory with the questions raised by the patient recognized by the AI intelligent system, and recognizes and executes the instructions of the patient and medical staff. The walking control unit is used to control the walking and movement of the lower limb part 3. The robot is built-in with a positioning module. After the medical staff selects the function and bed number on the operation screen, the camera on the robot's head takes pictures and views. The walking control unit controls the lower limb part 3 to move to the designated bed number to reach the position. After scanning the bed number identification and confirming that it is correct, the corresponding operation can be performed. The vital sign measurement unit completes the vital sign measurement through the infrared temperature measurement module and the blood pressure measuring instrument. The extended rehabilitation management function provides rehabilitation guidance for the patient through the rehabilitation plan stored in the memory. The medicine management and distribution unit includes an infusion medicine distribution module and an oral medicine distribution module, which are used to control the two functional arms 21 to respectively pop out the medicine storage drawers 214 to take infusion medicines or oral medicines. The medicine-taking supervision module is used to cooperate with the camera to complete the supervision and confirmation function when the patient takes medicine.

[0050] With the cooperation of each program module and hardware, the robot can realize functions such as intelligent vital sign detection, medicine distribution, query and communication, etc. Each module can also cooperate with each other. For example, when distributing oral medicines, the AI intelligent question-and-answer module has voice prompts throughout the process, and the camera monitors the whole process of the patient taking the pills 360 degrees. After the patient takes the medicine, he opens his mouth and takes a picture in front of the camera for record. If the patient does not take the medicine or interrupts taking the medicine or does not take the medicine into the mouth (the action characteristics of taking medicine are uploaded and input into the robot's system in advance for behavior feature recognition) during the camera shooting process, and leaves the camera area, the robot will alarm and call the nurse. Only after the nurse makes manual handling can the operation for the next patient be carried out. The robot can also provide rehabilitation guidance for the patient according to the patient's case and the experience data stored in the memory, reducing the workload of medical staff.

[0051] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.
