After the displacement component 2, the collection component 3, the installation component 4 and the drive component 5 are pulled out, a U-shaped frame is formed by two support plates 203 and a step plate 204. After being pulled out, there is no obstruction on both sides, and the staff can maintain the internal structure and install the blood collection tube in an unobstructed state. When the displacement component 2 is pulled out again, the sliding connection between the slider 201 and the slide rail 6 can support and limit the movement of the slider 201, so the support plate 203 and the step plate 204 can be pulled out of the shell along the slide rail 6. 1, after the displacement assembly 2 is pulled out, the blood draw tube consisting of the needle 418, the connecting sleeve 415, the fixing plate 416, the hose 417 and the plug 419 can be installed by using the multiple sets of the first sliding seat 401 and the second sliding seat 407 in cooperation. The two ends of the hose 417 are supported by using the two connecting sleeves 415 and the fixing plate 416 in cooperation. The needle 418 and the plug 419 are supported by the two connecting sleeves 415 respectively. During installation, the fixing plate 416 is inserted into the interior of the mounting seat 404 along the card slot 412. When the fixing plate 416 is inserted, it will contact the arc surface of the clamping plates 414 on both sides, thereby pushing the clamping plates 414 on both sides outward. At this time, the second spring 413 will be compressed, and the fixing plate 416 will be completely inserted into the mounting seat 404. After that, the position of the fixing piece 416 is limited by the setting of the card slot 412, and the fixing piece 416 is clamped by the rebound force of the second spring 413, so that the fixing piece 416 is firmly installed in the mounting seat 404. After the two fixing pieces 416 are inserted, the installation of the blood collection tube is completed. At this time, the state of the first moving block 403 is to provide support through the first spring 402, and the first spring 402 is in a natural stretching state, and the state of the second moving block 409 is that the first magnetic plate 408 and the second magnetic plate 410 above are in an adsorption state, that is, the overall state is that the needle 418 is below the jack 207, and the plug 419 is above the vacuum blood collection tube 303. At the positions of multiple groups of first sliding seats 401 and second sliding seats 407, multiple groups of blood collection tubes can be installed. The installation of blood vessels can complete the placement of multiple vacuum blood collection tubes 303 at the position of the follower ring 302. After the vacuum blood collection tube 303 is inserted into the placement groove, the friction force of the rubber sleeve 304 is used to limit the vacuum blood collection tube 303. The number of blood collection tubes and vacuum blood collection tubes 303 is equal, and they are respectively in vertical corresponding positions. One group of blood collection tubes corresponds to one vacuum blood collection tube 303 for one-time blood collection. After completing the preparation of blood collection tubes and vacuum blood collection tubes 303, the displacement component 2 is pushed into the shell 1 for use. At this time, there is a group of blood collection tubes and vacuum blood collection tubes 303 corresponding to the position of the jack 207. When starting to draw blood, the user is guided to place the index finger at the position of the groove 205 through the cooperation of the sign and voice, and the fingertip corresponds to the position of the jack 207.The shape of the groove 205 corresponds to the shape of a finger. At this time, the second motor 503 is running. After the second motor 503 is running, it can drive the support shaft 505 to rotate along through the connection between the second rotating shaft 504 and the pulley group. When the support shaft 505 rotates, it can drive the rotating block 506 to rotate along. Based on the non-operating state in Example 13, when the rotating block 506 rotates, the arc-shaped toothed plate 507 drives the second damping shaft 511 to rotate in the opposite direction through the engagement of the third gear 513. The rotation of the second damping shaft 511 drives the second cam 512 to rotate along. Referring to the motion state in Example 14, after the second cam 512 completes a rotation of 180 degrees, it will push the upper roller 406 upward through its convex surface. At this time, the upper roller 406 will pass The connection of the support 405 drives the first moving block 403 to move upward. When the first moving block 403 moves upward, it will compress the first spring 402 to shrink. At the same time, the upper fixing plate 416 and the connecting sleeve 415 are driven upward through the connection of the mounting seat 404. The connecting sleeve 415 drives the needle 418 to move upward. After the needle 418 moves upward, it extends from the position of the insertion hole 207 and pierces the user's fingertips. While the second cam 512 rotates to drive the needle 418 to move upward, the rotating block 506 continues to rotate, which will make the arc-shaped toothed plate 507 mesh with the second gear 510 and drive the first damping shaft 508 to rotate accordingly. After the rotating block 506 completes one circle of rotation, since the number of teeth of the arc-shaped toothed plate 507 is half of the third gear 513 and the second gear 510, the arc-shaped toothed plate 507 The third gear 513 and the second gear 510 can be driven in sequence to complete a half-circle rotation. When the first damping shaft 508 rotates, the first cam 509 can be driven to follow and complete a half-circle rotation. At this time, the convex surface of the first cam 509 rotates downward, which can push the lower roller 406 to move downward. The lower roller 406 drives the second moving block 409 and the lower mounting seat 404 to move downward through the connection of the support 405. When the mounting seat 404 moves downward, it can drive the plug 419 to move downward through the connection between the lower fixing plate 416 and the connecting sleeve 415. At the same time, the second moving block 409 moves downward, so that the lower first magnetic plate 408 and the second magnetic plate 410 are in an adsorption state. After the plug 419 moves downward, it can be inserted into the corresponding vacuum blood collection tube 303. The inside of the blood collection tube 303 is in a negative pressure state. At this time, the needle 418 is inserted into the fingertip, and the needle 418 is connected to the vacuum blood collection tube 303 through the connection of the hose 417 and the plug 419. The blood is sucked into the vacuum blood collection tube 303 by using the pressure difference. At this time, the blood collection is completed by waiting for a few seconds. After the blood collection is completed, the second motor 503 is started to drive the second shaft 504 to rotate one circle. At this time, the motion state is that the arc-shaped toothed plate 507 drives the third gear 513 and the second gear 510 to rotate half a circle in sequence, that is, the first cam 509 and the second cam 512 are driven to rotate half a circle to return to the initial position. When the first cam 509 continues to rotate, as shown in Figure 14, when the first cam 509 continues to rotate from the top support state,The upper roller 406 will be separated from the support of the first cam 509. Due to the special-shaped setting of the first cam 509, a large drop is generated below the large roller 406 when it is separated. Since the first spring 402 is in a compressed state, the rebound force of the first spring 402 can be used to drive the needle 418 to quickly move down and reset through the connection between the first moving block 403 and the mounting seat 404. At this time, the needle 418 is quickly withdrawn from the fingertip, effectively reducing the contact time between the needle 418 and the human body, thereby reducing pain. When the first spring 402 rebounds and drives the first moving block 403 to move down and reset, referring to Example 11, a buffer pad is provided at the inner bottom of the first sliding seat 401, and the first spring 402 rebounds and drives the first moving block 403 to rebound and move downward. The first movable block 403 contacts the buffer pad, and the deformation of the buffer pad plays a role in buffering and absorbing the impact force of the first movable block 403, thereby ensuring that the first movable block 403 is in a stable rebound state, that is, the displacement state is stable after the needle 418 is pulled out, to avoid the first spring 402 from rebounding violently and causing the needle 418 to cause harm to the user. After the needle 418 is pulled out, the second cam 512 rotates and resets. At this time, the second movable block 409 is adsorbed on the position of the first magnetic plate 408 below. After the roller 406 below is separated from the support of the second cam 512, it will still be in a downward position. Therefore, the plug 419 will always be inserted into the vacuum blood collection tube 303, to avoid directly pulling out the plug 419 and causing internal blood to be contaminated. The staff takes out the blood inside the vacuum blood collection tube 303 in a sterile environment, which ensures the safety of blood collection. After completing the blood collection of one user, a set of blood collection tubes and vacuum blood collection tubes 303 corresponding to the position of the jack 207 are used. At this time, the two first motors 208 are synchronously started to replace the positions of the blood collection tubes and the vacuum blood collection tubes 303. After the first motor 208 is started, it can drive the first gear 210 to follow the rotation through the connection with the first rotating shaft 209. The first gear 210 can drive the rotating tube 212 and the connecting ring 213 to follow the rotation through the engagement with the gear ring 215. When the rotating tube 212 rotates, it can also drive the follower ring 302 to follow the rotation through the connection of the connecting rod 301. The first plane bearing 211 is set to rotate the rotating tube 212. The second plane bearing 216 is provided to provide support for the rotation of the follower ring 302. The synchronous rotation of the upper and lower connecting rings 213 can drive multiple groups of first sliding seats 401 and second sliding seats 407 to follow the rotation, that is, drive multiple groups of blood collection tubes to follow the rotation. The rotation of the follower ring 302 can drive the vacuum blood collection tube 303 to rotate. At this time, the synchronous rotation of multiple groups of blood collection tubes and the vacuum blood collection tube 303 can play a role in exchanging positions. The blood collection tube and the vacuum blood collection tube 303 that complete the blood collection rotate out of the position of the socket 207, and the blood collection tube and the vacuum blood collection tube 303 next to them rotate to the corresponding position of the socket 207. At this time, the next user places his finger at the groove 205 position and starts the second motor 503 to perform the blood collection operation.When the multiple sets of blood collection tubes and vacuum blood collection tubes 303 inside the shell 1 are rotated and used in sequence, the closed environment inside the shell 1 is used to ensure that the needle 418 is not affected by external pollutants. At the same time, the use of the disinfection lamp 7 can sterilize and disinfect the needle 418 in real time to ensure that the needle 418 is not contaminated when in use. By placing multiple sets of disposable blood collection tubes and vacuum blood collection tubes 303 inside the shell 1 and using them in sequence to complete the blood collection operation, the device can complete the self-service blood collection work for multiple users after one material preparation work, without the need to frequently replace blood collection consumables, thereby improving blood efficiency. The working efficiency of the station is improved. Before the user places the finger in the groove 205 for blood collection, the lower part of the finger is placed on the soft pad 206, and the setting of the soft pad 206 provides soft support. At the same time, the electric push rod 8 is started to extend, and the sponge pad 9 is driven downward by the operation of the electric push rod 8. After the sponge pad 9 moves downward, it applies pressure to the upper part of the finger, and the pressure applied by it produces a sense of pressure on the finger in advance. At this time, the nerve endings at the finger position are compressed, which can divert the attention of the touch during blood collection, thereby reducing the pain caused by blood collection and improving the user's satisfaction with blood collection.
