The electric lifting rod 524 adjusts the lower shell 521 slightly based on the mounting strip 522 by lifting and lowering, thereby controlling the needle of the blood collection needle 53 to slightly tilt and point to the center of the bottom port of the isolation cover 5, so as to align it with the radial artery of the patient's wrist.

[0029] Specifically, the medical staff puts the device on the patient and directs the red laser emitted by the laser lamp 54 to the radial artery of the patient's wrist, that is, the center of the bottom port of the isolation cover 5 is aligned with the radial artery of the patient's wrist. At this time, the intelligent control box 1 retracts through the electric lifting rod 524 to drive the lower shell 521 to slightly deflect based on the mounting strip 522, so that the needle head of the blood collection needle 53 fixed between the lower shell 521 and the upper shell 523 is slightly tilted to point to the center of the bottom port of the isolation cover 5, that is, to the radial artery of the patient's wrist. At this time, the intelligent control box 1 controls the electric push rod 527 on the inner wall of the card slot 525 on the upper shell 523 to extend, and the electric push rod 527 extends. After the length is extended, the U-shaped clamping plate 526 is pushed to slide in the clamping groove 525 on the upper shell body 523, thereby pushing the blood collection needle 53 fixed between the lower shell body 521 and the upper shell body 523 to slide along the clamping groove 525, thereby pushing the blood collection needle 53 to slide along the clamping groove 525 in the slightly inclined lower shell body 521 and then obliquely penetrate into the radial artery of the patient's wrist, so that the blood in the radial artery of the patient's wrist is introduced into the external sample tube for storage through the blood collection needle 53 along the blood transfusion tube 531, automatically completing the automatic blood collection of the patient's radial artery. On the contrary, after the blood collection is completed, the electric push rod 527 retracts to drive the blood collection needle 53 to automatically withdraw from the radial artery of the patient's wrist, which is convenient to use.

[0030] In order to enhance the healing effect of the puncture wound after the patient completes the blood collection, Figure 1-Figure 2 , Figure 6 and Figure 8-Figure 9 As shown, this implementation provides the following preferred technical solutions: The auxiliary strap 31 includes a connecting pipe 311 movably embedded in the bottom plates on both sides of the cold water box 3 and a rotating disk 312 fixedly connected to the bottom of the connecting pipe 311. The rotating disk 312 is hollow. The connecting pipe 311 is symmetrically arranged about the isolation cylinder 14. The connecting pipe 311 movably penetrates the bottom plate of the cold water box 3 and a protruding chuck is arranged. The connecting pipe 311 is movably fixed to the bottom plate of the cold water box 3 by the protruding chuck. At the same time, a sealing ring and other anti-leakage measures are arranged between the contact end surface of the bottom plate of the cold water box 3 and the protruding chuck. A second gear ring 313 is fixedly sleeved on the outer wall of the rotating disk 312, and the two sides of the bottom of the rotating disk 312 are respectively fixedly connected with the connected cold water inlet pipe 314 and the cold water outlet pipe 315, and the outer wall of the cold water inlet pipe 314 and the cold water outlet pipe 315 near one end of the rotating disk 312 has a movable sleeve limit plate 316, and the side walls of the joints at the other ends of the cold water inlet pipe 314 and the cold water outlet pipe 315 are evenly fixedly connected with a circulation pipe 317, and the outer wall of the circulation pipe 317 is wrapped with a gauze sleeve 318.

[0031] The top of the second gear ring 313 is arranged in contact with the bottom of the cold water box 3, and a receiving opening is opened on the side wall of the isolation tube 14 corresponding to the second gear ring 313. One end of the second gear ring 313 extends to the inside of the isolation tube 14 through the receiving opening. A micro motor 15 is fixedly connected to the bottom plate of the intelligent control box 1. The transmission shaft of the micro motor 15 penetrates the bottom plate of the intelligent control box 1 and extends to the isolation tube 14. A driving gear 16 is fixedly connected to the bottom of the transmission shaft of the micro motor 15. A chain 17 is movably sleeved on the outer wall of the driving gear 16, and the other end of the chain 17 is movably sleeved on the outer wall of the second gear ring 313.

[0032] A water pipe 32 is fixedly connected to the outer wall of one side of the cold water box 3. The water pipe 32 is externally connected to a cold water circulation pump. There are two water pipes 32, one for water inlet and the other for water outlet to realize water circulation and renewal in the cold water box 3. The driving gear 16 is suspended above the top port of the regulating cylinder 6, and the setting height of the driving gear 16 is the same as the setting height of the second gear ring 313. The driving gear 16 is located at the midline of the line connecting the second gear rings 313. The driving gear 16 and the two sets of second gear rings 313 support the chain 17 in a triangular shape.

[0033] Specifically, when the patient wears the device, the patient's wrist is put between the circulation tubes 317 on both sides of the isolation tube 14, so that the bottom of the isolation cover 5 fits the patient's wrist skin, and the limiting plate 316 is suspended on the side of the patient's wrist away from the circulation tube 317. After the isolation cover 5 and the radial artery of the patient's wrist are calibrated, the intelligent control box 1 is started to control the micro motor 15, and the micro motor 15 drives the active gear 16 to rotate. The active gear 16 uses the chain 17 to drive the second gear ring 313 suspended on the outer side of the two ends of the adjustment tube 6 to rotate. The second gear ring 313 drives the rotating disk 312 to rotate at the bottom of the cold water box 3 based on the connecting tube 311. When the rotating disk 312 rotates, it drives the cold water inlet pipe 314 and the cold water outlet pipe 315 at both ends of the circulation tube 317 to be twisted. Because the water in the cold water inlet pipe 314 and the cold water outlet pipe 315 will not be deformed, and the limiting plate 316 cooperates with the patient's wrist to prevent the patient from deforming. 16, the cold water inlet pipe 314 and the cold water outlet pipe 315 on the side of the limit plate 316 close to the middle turntable 312 are twisted, and the two are twisted. Push the limit plate 316 to move toward the patient's wrist to shrink the cold water inlet pipe 314 and the cold water outlet pipe 315, and cooperate with the circulation pipe 317 in the gauze sleeve 318 to automatically lock the patient's wrist, so as to realize the automatic wearing and fixing of the patient's wrist by the device, and on the contrary, the wearing lock can be released. After the patient's puncture and blood collection is completed, the low-temperature water in the cold water box 3 flows through the cold water inlet pipe 314, the circulation pipe 317 and the cold water outlet pipe 315 under the action of the external circulation pump, and the low-temperature water is passed through the circulation pipe 317 through the gauze sleeve 318 to apply low-temperature ice to the patient's arms on both sides of the puncture wound, so as to reduce the blood flow circulation effect of the patient's wrist, thereby promoting the hemostasis and healing effect of the patient's radial artery puncture wound, which is convenient and practical.
