The shell 3 is internally provided with a three-station clamping device 32 which can be vertically lifted and horizontally rotated for clamping the blood collection needle 31. The stations of the three-station clamping device 32 respectively correspond to the blood collection hole 30, the blood collection needle placement window 39 and the discarding port 37 to realize the three-station conversion and complete the blood collection action. A transfer robot 34 which clamps the vacuum tube 33 and drives it to move horizontally is arranged at a position corresponding to the blood collection hole 30 above the three-station clamping device 32. A vacuum tube placement table 35 for placing an empty vacuum tube 33 and an output track 36 for taking out the vacuum tube 33 after blood collection are completed are respectively arranged on both sides of the transfer robot 34.

[0024] The three-station clamping device 32 includes a three-station clamping platform 321 and a driving device 322 for driving the three-station clamping platform 321 to rise and fall and rotate at equal angles. In order to clamp the blood collection needle 31, the three-station clamping platform 321 includes a platform frame 3210 and three clamping stations 3211 equally distributed around the axis of the platform frame 3210. The clamping station 3211 includes an ejection cylinder 3212 fixed to one side of the platform frame 3210. The ejection part of the ejection cylinder 3212 is fixedly connected to a push plate 3213. The upper and lower ends of the push plate 3213 are respectively provided with blood collection needle clamping claws 3214 for clamping the upper and lower ends of the blood collection needle 31.

[0025] In order to drive the lifting and equal-angle rotation of the three-station clamping platform 321, the driving device 322 used includes a clamping device lifting cylinder 3220 fixed on the upper end surface of the shell 3, and the ejection part of the clamping device lifting cylinder 3220 is vertically downwardly connected to the station conversion motor 3222 through the connecting plate 3221, and the rotating shaft of the station conversion motor 3222 is downwardly connected to the axis of the three-station clamping platform 321.

[0026] The transfer robot 34 includes a clamping seat 341 fixed on the upper end surface of the shell 3, an electric clamping claw 342 sliding left and right along the clamping seat 341 is arranged at the lower part of the clamping seat 341 in order to clamp the vacuum tube 33, and a transverse electric cylinder 343 is arranged on one side of the clamping seat 341 to drive the electric clamping claw 342 to slide left and right.

[0027] In order to place the vacuum tube 33 into the shell 3 and quickly move the vacuum tube to the clamping position specified by the transfer robot 34, the vacuum tube placement table 35 includes a rotating electric cylinder 353 with an upward rotating axis and a placement platform 351, wherein the rotating axis of the rotating electric cylinder 353 is connected to the center of the lower end surface of the placement platform 351, and vacuum tube placement seats 352 are arranged at both ends of the placement platform 351.

[0028] In order to fix the arm and adjust the position of the arm artery to correspond to the needle of the blood collection needle 31, the arm fixing platform 11 includes a lower plate 111, a middle plate 112 and an upper plate 113. The lower end face of the lower plate 111 is fixed on the base 1, and the lower plate 111 and the middle plate 112 located above are slidably connected by a longitudinal slide rail 124 arranged longitudinally therebetween. The middle plate 112 and the upper plate 113 arranged above are slidably connected by a transverse slide rail 125 arranged transversely therebetween. In order to automatically correspond the arm artery to the blood collection needle, the middle plate 112 and the upper plate 113 are respectively driven to translate by horizontal push electric cylinders 126 in different directions at the lower ends, and arm fixing devices 128 are fixed at both ends of the upper end face of the upper plate 113.

[0029] In order to facilitate the staff to quickly fix the blood collection arm, the arm fixing device 128 includes a U-shaped pad block 1281 fixed on the upper end face of the upper plate 113, and the end of one side wall of the pad block 1281 is rotatably connected to an upper pressure plate 1282 with an opening opposite to the pad block 1281, and the pad block 1281 and the upper pressure plate 1282 are clamped and connected by a fixing buckle 1283.

[0030] Compared with other detectors, Doppler ultrasound detectors have the advantages of being cheap, non-invasive, and having a large detection depth, so the artery detection device 38 is a Doppler ultrasound detector.

[0031] In order to uniformly manage and collect discarded needles, a recovery frame 371 is arranged directly below the discard port 37 , and the recovery frame 371 is fixed to one side of the base 1 .

[0032] In order to ensure that the vacuum tube 33 can accurately fall into the collection area when the transfer robot 34 places the vacuum tube 33, the output track 36 has a U-shaped cross-section, the middle part of the output track 36 is fixedly connected to the shell 3, and one end of the output track 36 is located below one side of the transfer robot 34, and the other end is tilted downward to pass through the shell 3.

[0033] As for the use process of the present invention, first place the arm on the pads 1281 at both ends of the upper end surface of the upper plate 113, then press the arm with the upper pressing plate 1282 and fix the pads 1281 to the upper pressing plate 1282 through the fixing buckle 1283; the lifting platform electric cylinder 4 drives the artery detection device 38 on the housing 3 to rise and fall to an easily identifiable position, detects the position of the artery and the depth required for blood sampling, controls the arm fixing platform 11 that can be moved horizontally to drive the arm, and moves the blood vessels on the arm to be directly below the blood sampling hole 30;

[0034] After the upper and lower ends of the blood collection needle 31 are fixed to the clamping station 3211 through the blood collection needle placement window 39, the empty vacuum tube is placed on the vacuum tube placement seat 352. At this time, the station conversion motor 3222 on the driving device 322 rotates 60°, and the synchronous rotating electric cylinder 353 drives the placement platform 351 to rotate 180° and moves the empty vacuum tube 33 to the lower side of the transfer manipulator 34. The transverse electric cylinder 343 pushes the electric clamp 342 to the position of the vacuum tube 33 to clamp the vacuum tube 33 and move it to the second station blood collection point. At this time, the blood collection needle 31 is located at the second station. The ejection part of the clamping device lifting electric cylinder 3220 drives the blood collection needle 31 clamped on the three-station clamping platform 321 and the butt end of the vacuum tube 33 is inserted into the upper vacuum tube 33. The electric clamp 342 releases the vacuum tube 33, and the clamping device lifting electric cylinder 3220 drives the needle head of the blood collection needle 31 downward to the calculated position to complete blood collection.

[0035] The lifting electric cylinder 3220 drives the three-station clamping platform 321 to move upward, and the electric clamp 342 clamps the vacuum tube 33 and places it on the output track 36 to take out the vacuum tube 33 after blood collection. The electric clamp 342 clamps the vacuum tube 33 and drives the station conversion motor 3222 on the device 322 to rotate 60°. The ejection electric cylinder 3212 on one side of the platform frame 3210 ejects the push plate 3213 and releases the blood collection needle clamps 3214 at the upper and lower ends, which are respectively provided with clamping the upper and lower ends of the blood collection needle 31, and the discarded blood collection needle 31 is thrown into the recycling frame 371 through the discard port 37.

[0036] The present invention uses a Doppler ultrasonic detector to automatically identify the position of the artery and determine the depth of blood sampling, thereby solving the problem that the current manual blood sampling cannot quickly find the patient's artery for blood sampling when encountering a patient with unclear arteries. The arm fixing platform is driven by the detected data to move the arm's artery position to the corresponding blood sampling position. The blood collection needle is driven to complete blood collection through the combined application of the lifting electric cylinder and the rotating platform. The three workstations are quickly switched to replace the original complicated processes of manually discarding waste needles and collecting vacuum tubes after blood collection, thereby greatly reducing the requirements for the manual blood collection ability of the staff, alleviating the staff's work intensity and increasing efficiency.
