[0023] See also Figure 1-4, a gynecological examination blood sampling auxiliary device, comprising an auxiliary plate 1, an adjusting mechanism 2 is arranged inside the auxiliary plate 1, and a fixing mechanism 3 is arranged above the auxiliary plate 1;

[0024] The adjusting mechanism 2 includes a servo motor 201, the right end of the servo motor 201 is fixedly connected to the left side of the auxiliary plate 1, a protective shell 4 is arranged on the outside of the servo motor 201, and the right side of the protective shell 4 is fixedly connected to the left side of the auxiliary plate 1. The protective shell 4 can protect the servo motor 201 and prevent the servo motor 201 from being disturbed by external factors during operation. At the same time, it can also improve the stability of the servo motor 201 during operation, thereby increasing the stability of the device.

[0025] The output end of the servo motor 201 power is fixedly connected to a threaded rod 202. The right end of the threaded rod 202 passes through the auxiliary plate 1 and extends to the inside of the auxiliary plate 1. The outer surface of the threaded rod 202 is sleeved with an auxiliary bearing 5, and the auxiliary bearing 5 is embedded in the inside of the auxiliary plate 1. The auxiliary bearing 5 can effectively reduce the friction generated by the threaded rod 202 during rotation, making the threaded rod 202 more sensitive when rotating. At the same time, it can also reduce the loss rate of the threaded rod 202 and increase the service life of the threaded rod 202.

[0026] The outer surface of the threaded rod 202 is threadedly connected to a moving block 203, and the moving block 203 is slidably connected to the inside of the auxiliary plate 1. The upper surface of the moving block 203 is fixedly connected to a placement block 204, and the bottom surface of the placement block 204 is fixedly connected to two sliding blocks 6. Each sliding block 6 is slidably connected to the inside of the auxiliary plate 1. The sliding block 6 can move simultaneously with the placement block 204, and use the friction generated by itself on the auxiliary plate 1 during the movement to improve the stability of the placement block 204 during movement, thereby further improving the stability of the device.

[0027] The fixing mechanism 3 includes two electric telescopic rods 301, and the ends of the two electric telescopic rods 301 that are away from each other are fixedly connected to the inner wall of the placement block 204. The telescopic end of each electric telescopic rod 301 is fixedly connected to a square outer tube 302, and the interior of each square outer tube 302 is slidably connected to a square inner tube 303. The front and back sides of the auxiliary plate 1 are fixedly connected to mounting blocks 7, and the upper surface of each mounting block 7 is provided with a fixing hole 8. By utilizing the cooperation between the mounting block 7 and the fixing hole 8, the auxiliary plate 1 can be conveniently fixed to the required position through the fixing hole 8, thereby avoiding the situation where a lot of time is spent on the installation of the auxiliary plate 1, thereby improving the convenience of the device.

[0028] The inner wall of each square outer tube 302 is fixedly connected to a pressure sensor 304, and the side of each square inner tube 303 that is away from each other is fixedly connected to a pressure measuring spring 305. The ends of the two pressure measuring springs 305 that are away from each other are respectively fixedly connected to the ends of the two pressure sensors 304 that are close to each other. The upper surface of the auxiliary plate 1 is fixedly connected to a support platform 9, and the inner wall of the support platform 9 is fixedly connected to a cushion 10. Relying on the cooperation of the support platform 9 and the cushion 10, a good supporting point can be provided for the patient's arm, increasing the external support area of ​​the patient's arm during blood drawing. At the same time, the cushion 10 can increase the comfort of the patient's arm when it is in contact with the support platform 9.

[0029] Each pressure sensor 304 is electrically connected to the electric telescopic rod 301 through a wire, and the side surfaces of the two square inner tubes 303 that are close to each other are fixedly connected with a clamping plate 306, and the side surfaces of the two clamping plates 306 that are close to each other are fixedly connected with a sponge pad 307. The left and right side surfaces of the support platform 9 are fixedly connected with reinforcement blocks 11, and the bottom surface of each reinforcement block 11 is fixedly connected to the upper surface of the auxiliary plate 1. The reinforcement blocks 11 can increase the fixed connection area between the support platform 9 and the auxiliary plate 1 to increase the firmness of both parties, prevent the support platform 9 from breaking or shaking after long-term use, and improve the durability of the support platform 9.

[0030] The working principle of the utility model is as follows: when in use, firstly connect the servo motor 201, the electric telescopic rod 301 and the pressure sensor 304 to the power supply. When it is necessary to clamp the patient's arm, start the servo motor 201 first. The protective shell 4 can increase the stability of the servo motor 201 during operation. The power generated by the servo motor 201 is used to drive the threaded rod 202 to rotate forward or reverse. The auxiliary bearing 5 can reduce the friction generated by the threaded rod 202 during rotation, so that the moving block 203 drives the placement block 204 to move left and right. The sliding block 6 can improve the stability of the placement block 204 during movement. When it is adjusted to a suitable distance from the support table 9, it can stop. The distance between the placement block 204 and the support table 9 can be conveniently adjusted according to the length of the patient's arm. Then the patient's arm is placed on the surface of the placement block 204 and passes through the support table 9. The support table 9 can increase the support area of ​​the patient's arm. Then start the electric telescopic rod 301, and use the electric telescopic rod 301 to push the two square outer tubes 302 to move relative to each other, so that the pressure measuring spring 305 drives the square inner tube 303 to move at the same time, so that the clamping plates 306 move relative to each other, and rely on the clamping plates 306 to clamp the patient's arm. When the clamping plates 306 touch the patient's arm, the pressure measuring spring 305 will be compressed. At this time, the pressure sensor 304 can sense the pressure of the pressure measuring spring 305, and when the pressure reaches a preset value, it sends an electrical signal to the electric telescopic rod 301 through a wire to stop it, so as to avoid the patient's discomfort caused by excessive clamping force, and also prevent the possibility of the patient's arm moving due to insufficient clamping force. When loosening is required, start the electric telescopic rod 301 to drive the two clamping plates 306 away from each other, which not only increases the patient's comfort during blood collection, but also improves the use effect of the blood collection aid.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
