Detailed ways

Please refer to Figures 1 to 3. The present utility model provides the following technical solution: including a front support block 1, a rear support block 11 and a puncture needle 15. The tops of the front support block 1 and the front support block 1 are slidingly connected with two installation blocks 12. , an arc plate 13 is fixedly connected between the two installation blocks 12, a connecting plate 2 is fixedly connected between the front support block 1 and the rear support block 11, and side plates 21 are slidingly connected to both sides of the connecting plate 2. The two side plates 21 are fixedly connected with sliding rods 22, and the outer sides of the sliding rods 22 are equipped with springs 221. The sliding rods 22 are slidably connected with a sliding plate 23, and the bottom of the sliding rod 23 is slidingly connected with a pressure block 24.

In this embodiment: the front support block 1 and the rear support block 11 are used to support the patient's forearm and rear arm respectively, and the arms can be placed on the front support block through the arc-shaped grooves on the front support block 1 and the rear support block 11 1 and the rear support block 11, and the mounting block 12 slidably connected to the front support block 1 and the rear support block 11 can slide to the front support block 1 and the rear support block 1 after the arm is on the front support block 1 and the rear support block 11 11 top, the upper part of the patient's arm is limited through the arc plate 13, so that the arm is limited on the front support block 1 and the rear support block 11, and then the connecting plate 2 is passed between the front support block 1 and the rear support block 11. The connection is made so that the front support block 1 and the rear support block 11 are connected into one body, thereby limiting the position of the patient's arm. When the patient's arm is punctured to collect plasma through the puncture needle 15, the patient's arm can be prevented from being stung. The arm bends greatly after being stimulated, causing the head of the puncture needle 15 to puncture out of the blood vessel, thus affecting the normal work of collecting plasma from the patient, and easily causing harm to the patient. After the patient completes the collection of plasma, the puncture needle 15 is removed from the blood vessel. After the patient's arm is taken out, the patient's puncture site needs to be pressed to avoid continuous bleeding, which is prone to bacterial growth and other adverse effects. The side plates 21 are slidably connected on both sides of the connecting plate 2, and the side plates 21 are fixedly connected through their top ends. The sliding rod 22 installs the sliding plate 23, and the sliding rod 23 slides up and down on the sliding rod 22. At the same time, the sliding rod 22 is connected by the spring 221, so that it is subject to the elastic force from the spring 221, causing the sliding plate 23 to move downward, affecting the patient's health. The arm is pressed, and the side plate 21 slides outside the connecting plate 2. It can be slid to the puncture position so that it corresponds to the puncture position. After sliding downward, the patient's arm can be punctured through the pressing block 24 at the bottom of the slide plate 23. Press the bottom part to prevent continuous bleeding. At the same time, the pressing block 24 slides on the bottom of the slide plate 23, and can be taken out from the bottom of the slide plate 23 by sliding, so that it can be taken out for cleaning and disinfection after use, so that the device can It effectively prevents the patient from easily touching the wound with unsterilized hands when pressing the wound, and does not affect the patient's own hand operation.

The tops of the front support block 1 and the rear support block 11 are both provided with arcuate grooves, the front support block 1 is fixedly connected with a tourniquet 14, and one side of the connecting plate 2 is fixedly connected with a binding band 27 for binding the puncture needle 15. The other side of the connecting plate 2 is provided with a buckle for limiting the restraint strap 27; the arc-shaped grooves on the tops of the front support block 1 and the rear support block 11 enable the patient's arms to rest on the front support block 1 and the rear support block 11. The tourniquet 14 fixedly connected to the front support block 1 is used to restrain the patient's rear arm to exert a pulse pressure effect. The restraint belt 27 is used to bypass the puncture needle 15 and then buckle one end of the tourniquet 14 . Fix, so that when the puncture needle 15 collects plasma, it is fixed to maintain the corresponding position.

A limit slot 122 is provided at the connection between the front support block 1 and the installation block 12. The bottom end of the installation block 12 is fixedly connected to the limit block 121. The limit slot 122 is slidingly connected to the limit block 121; the front support block 1 and the installation block 12 pass through the limit block 121. The position block 121 and the limiting groove 122 form an interconnected assembly, so that the installation block 12 can be limited on the front support block 1 and the rear support block 11 and can be taken out to facilitate fixing the patient's arm.

A slider 241 is fixedly connected to the connection between the pressure block 24 and the slide plate 23. A chute 231 is provided at the bottom of the slide plate 23 for limiting the slide block 241. An alcohol pad 242 is detachably connected to the bottom of the pressure block 24. One end of the pressure block 24 is fixed. A tie rod 243 is connected; the pressure block 24 and the slide plate 23 form an interconnected assembly through the slide block 241 and the chute 231, so that when the pressure block 24 is under the slide plate 23, it will not separate from the slide plate 23, thereby limiting it. When pushed, the sliding plate 23 can be slid out to clean the sliding plate 23. The alcohol pad 242 removably connected to the bottom of the pressure block 24 is used to prevent bacterial growth, and the alcohol pad 242 can be removed and replaced to ensure hygiene during use. The pull rod 243 can It is convenient for the user to separate the pressing block 24 from the bottom of the slide plate 23 by pulling the pull rod 243 .

A fixed block 25 is fixedly connected to one side of the two side plates 21, and a vertical pole 26 is fixedly connected to the top of the fixed block 25. The outer wall of the vertical pole 26 is rotationally connected to the limiting plate 261; the fixed block 25 fixedly connected to one side of the side plate 21 is used for The vertical pole 26 is fixed, and the limiting plate 261 connected by rotation at the top of the vertical pole 26 protrudes from the surface of the vertical pole 26 so that its protruding end can be rotated below the sliding plate 23 to limit its position and avoid the pulling of the sliding plate 23 by the spring 221 The lower part contacts the patient's skin in advance, which affects the use effect of the alcohol pad 242. When the limiting plate 261 rotates outside the sliding plate 23, the sliding plate 23 can move downward.

The working principle and usage process of the utility model: through the arc-shaped grooves on the front support block 1 and the rear support block 11, the arm can be placed on the front support block 1 and the rear support block 11, and then through the arc-shaped plate 13, the upper part of the patient's arm To limit the position, the front support block 1 and the rear support block 11 are connected through the connecting plate 2, so that the front support block 1 and the rear support block 11 are connected into one body, thereby limiting the position of the patient's arm. When the patient's arm is undergoing puncture When the needle 15 performs puncture and plasma collection, when the patient's arm is stung, it can prevent the patient's arm from bending greatly after being stimulated, causing the head of the puncture needle 15 to puncture the blood vessel, thereby affecting the normal work of collecting plasma from the patient. , after the patient collects plasma, the puncture part of the patient's arm can be pressed through the pressing block 24 at the bottom of the slide 23 to prevent continuous bleeding and effectively prevent the patient from easily touching the wound with unsterile hands when pressing the wound. to the wound and does not affect the patient's own hand operations.
