The specific implementation mode is as follows:

the first embodiment is as follows:

as shown in fig. 1 and fig. 2, the compression type radial artery tourniquet of the present invention is mainly used for hemostasis after puncture of the radial artery 51 at the wrist 5, and comprises an inner side plate 1, a dorsal side plate 2, an elastic band 3 and a compression member 4. The inner side of the inner side plate 1 is provided with a pressing part 4, the elastic band 3 is further provided with a back side plate 2, the back side plate 2 comprises a transverse plate 21 and a vertical plate 22 which are arranged in a cross mode and connected together, the vertical plate 22 is located on one side of the back of the hand, and the transverse plate 21 is arranged on the elastic band 3.

The width of the back side plate vertical plate 22 is generally smaller than the distance between the basilic vein 52 and the cephalic vein 53 at the back of the hand of a human body, the length of the transverse plate 21 is slightly larger than the distance between the basilic vein 52 and the cephalic vein 53 at the back of the hand of the human body, and the back side plate vertical plate 22 is placed between the basilic vein 52 and the cephalic vein 53 at the back of the hand when the hand-held blood circulation treatment device is used, so that the vein is prevented from being pressed, the blood backflow of the hand is not influenced, and the occurrence of limb swelling. Due to individual difference, the spacing between the basilic vein 52 and the cephalic vein 53 is different, and the transverse plate 21 can be opened when the length is larger than the spacing between the two veins, so as to prevent the veins from being pressed.

As shown in fig. 4, oppression piece 4 and interior side plate 1 adopt detachable swing joint, and the embodiment takes snap-fastener type swing joint as an example, and swing joint makes oppression piece 4 can rotate certain angle along with human wrist 5 shape in the use to make each point atress of puncture point oppression piece 4 more even, it is comparatively comfortable, do benefit to hemostasis simultaneously. The inboard of interior plate 1 is equipped with button female 11, and oppression piece 4 is equipped with button male 41, and oppression piece 4 and interior plate 1 can separate completely, and the part that contacts human blood simultaneously only oppresses piece 4, and the abandonment oppresses piece 4 after the use can, and the surplus portion can disinfect and retrieve and recycle, realizes environmental protection resources are saved, practices thrift medical cost and reduces the purpose of patient's economic burden.

The fixed end of the elastic belt 3 is connected to one side of the inner side plate 1, the movable end of the elastic belt 3 is adjustably and movably connected to the other side of the inner side plate 1 to form a ring-shaped structure, the embodiment takes the ring buckle connection as an example, the elastic belt 3 passes through the ring buckle 32 and is reversely folded back to be connected to the elastic belt 3 through the nylon fastener 31, the other side of the inner side plate 1 is provided with an inner side plate clamping groove 12 which is matched with the ring buckle 32, and the purpose of adjusting the length of the elastic belt to adapt to the use of different.

The elastic band 3 is made of anti-slip latex yarn and polyester material, and has the characteristics of elasticity, comfort and skid resistance.

Example two:

in this embodiment, as shown in fig. 1, the two sides of the lateral plate 21 are respectively provided with a lateral plate slot 23, the elastic band 3 passes through the lateral plate slots 23, so that the lateral plate 21 can be slidably adjusted relative to the elastic band, and the position of the vertical plate 22 can be adjusted, so that the vertical plate 22 is located between the basilic vein 52 and the cephalic vein 53 on the back of the hand. Meanwhile, if the patient is a special patient with the space between the basilic vein 52 and the cephalic vein 53 at the back of the hand being smaller than the width of the vertical plate 22, the position of the vertical plate 22 can be adjusted under the circumstance that the vertical plate 22 only presses one vein, and although the blood reflux speed of the hand is influenced to a certain extent, the occurrence of swelling, numbness and cyanosis of the extremities can be prevented or reduced.

Example three:

optionally, as shown in fig. 3, a silica gel layer 6 is disposed on the pressing member 4 and the surface of the vertical plate 22 of the dorsal plate contacting the human body, and the thickness of the silica gel layer 6 is 2mm, so that the whole body is uniformly stressed and comfortable, and hemostasis is facilitated.

Example four:

in the embodiment, the width of the vertical plate 22 of the dorsal plate is 20mm, the length of the horizontal plate 21 is 40mm, the vertical plate 22 is placed between the basilic vein 52 and the cephalic vein 53, and the elastic band is arranged on the horizontal plate 21 in an overhead manner, so that the elastic band 3 can avoid the basilic vein 52 and the cephalic vein 53 at the back of the hand without influencing the blood backflow of the hand, thereby avoiding the occurrence of limb swelling, numbness and cyanosis.

Example five:

optionally, the length, width and height of the inner side plate 1 are 60mm × 20mm × 2mm, the length, width and height of the elastic band 3 are 160mm × 15mm × 1mm, the length of the inner side plate 1 plus the length of the elastic band 3 can adapt to the wrists 5 of most patients, and meanwhile, the elastic band 3 is 15mm wide, so that the compression on the wrists 5 can be reduced, and the patients feel comfortable. The length, width and height of the pressing piece 4 can be 30mm multiplied by 20mm multiplied by 2mm, and the size can well cover the puncture point, and meanwhile, the hemostatic effect is not influenced because the pressure of the puncture pressing point is too small. The length, width and height of the transverse plates 21 and the vertical plates 22 of the dorsal side plate can be selected to be 40mm multiplied by 20mm multiplied by 2mm, so that the size of the dorsal side plate 2 is moderate, and the movement of the wrist 5 cannot be influenced excessively.
