The second restriction member 320 is located at one end of the wrist, also referred to as the proximal end, and the proximal end of the second restriction member 320 is fixedly connected to the lower side of the wrist band 210, which is the side of the wrist band 210 that fits against the back side of the patient's wrist; the second restriction member 320 is located at one end of the palm portion, which is also referred to as a distal end, and the distal end of the second restriction member 320 is fixedly connected to the lower side of the palm cover 110, where the lower side refers to the side of the palm cover 110 attached to the back of the patient's palm.

Preferably, the distal end of the first restriction member 310 can be connected to the palm sleeve 110 near the middle in the upper region thereof, so that the first restriction member 310 can span the palm of the human body, the connection between the palm and the wrist, thereby performing a more comprehensive restriction function. The first limiting member 310 has an arc fitting with the palm side shape of the wrist of the patient, and the arc fits with the convex shape of the flesh portion at the junction of the palm and the wrist of the human body, and fits with the slightly concave shape of the palm center of the palm of the human body. The second restriction 320 has at least a curvature that conforms to the shape of the pisiform of the dorsal aspect of the patient's wrist. The first limiting piece 310 and the second limiting piece 320 can be made of degradable plastic materials with strong shaping capability and difficult deformation after shaping, and can play a role in fixing the wrist of a patient. Preferably, polylactic acid PLA plastic is adopted, the plastic material can be automatically degraded, the environment is protected, the cost is lower, the melting point of the material is low, the material is easy to shape, the material has a certain antibacterial property, and the material has wide application in the medical field.

The adjusting member 220 may be provided in a form in which a screw and a set nut are engaged with each other to perform an adjusting function. The screw rod can penetrate through the surface of the wristband 210, wherein one end of the screw rod, which is positioned on the outer surface of the wristband 210, is wrapped with a rotating handle which is easy to be held by a patient, the inner side of a positioning nut matched with the screw rod is provided with threads which can be meshed with the outer surface of the screw rod, and the patient can control the screw rod to move up and down by rotating the rotating handle, so that the pressing piece 230 connected to the screw rod is controlled to reduce or increase the pressing force to the position in a manner of being far away from or close to the hemostatic point of the patient.

Preferably, since the proximal end of the first restriction member 310 is connected to the pressing member 230 and the distal end is fixedly connected to the upper side of the palm sleeve 110, the relative position of the distal end of the first restriction member 310 is unchanged while the proximal end of the first restriction member 310 is driven by the up-and-down movement of the pressing member 230, so that the first restriction member 310 can perform a "swing" like movement during the manipulation of the adjustment member 220 by the patient. During "rocking" the proximal end of the first restriction member 310 is capable of simultaneously applying different amounts of pressure to the skin tissue adjacent the hemostatic spot of the patient in coordination with the movement of the compression member 230, exhibiting different degrees of restriction. In general, the wound of the patient after the radial artery interventional therapy is a process of gradually recovering over time, and after a period of nursing, the pressure of the compression hemostasis point does not have to be maintained at a larger value just after the therapy is completed, but the compression force on the patient can be gradually reduced by controlling the adjusting member 220, so that the restriction effect of the first restriction member 310 on the patient is also presented as a dynamic smaller process, and the form is more humanized for the patient while the rehabilitation training effect is not lost.

Preferably, the connection between the distal end of the first limiting member 310 and the upper side of the palm sleeve 110 may be hinged by a hinge, wherein one piece of the hinge is fixed at the upper side edge of the palm sleeve 110, and the other piece of the hinge is connected to the distal end of the first limiting member 310, and the opening and closing direction of the hinge is the same as the direction in which the proximal end of the first limiting member 310 approaches or separates from the second limiting member 320. Such an arrangement allows the "swing" direction of the first restriction member 310 controlled by the adjustment member 220 to be determined, avoiding the occurrence of a situation in which the curvature thereof is deteriorated in conformity with the shape of the wrist of the patient, resulting in the occurrence of an indentation in the skin thereat, and alternatively, the hinge is made of stainless steel, has high strength and durability, and can withstand long-term use without being easily damaged.

Preferably, training portion 100 further includes finger cuff 120 and spring 130, finger cuff 120 being configured as a cap-like structure that conforms to the shape of the patient's finger with the top of the cap-like structure closed and the brim enclosing a ring slightly larger than the diameter of the patient's finger. The shape enables the finger to be worn on the finger tip of the patient easily, and the two ends of the elastic member 130 are fixedly connected with the fingerstall 120 and the palm sleeve 110 respectively, wherein the elastic member 130 can be a pull rope with a certain elasticity, and the length of the elastic member is shorter than the length of the finger of the patient. One end of the elastic member 130 connected with the finger stall 120 is fixedly connected to the top end of the outer surface of the finger stall 120, so as to reserve a space into which the finger tip of the patient extends.

Preferably, the finger cuff 120 has a securing strap thereon that helps to bind it to the patient's finger, which may be in the form of an annular elastic strap that can be looped over the finger of the patient from the patient's fingertip position around the top of the finger cuff 120 to aid in securing, avoiding accidental removal of the finger cuff 120 by the patient while training the finger with the training portion 100.

Preferably, the second limiting member 320 is provided with a pressing strip adapted to the radian of the second limiting member, and the pressing strip can be made of a rubber material with certain flexibility, so that the pressing sense of the back side and the palmar back of the wrist of the patient can be relieved to a certain extent, and the limiting effect on the wrist of the patient is not lost.

Preferably, compression member 230 should be positioned within wristband 210 at a location corresponding to the patient's radial artery puncture site. In general, the palm of the patient is upward, the arterial pulsation is most obvious at the position of the wrist joint, which is 2 cm away from the palm, and is the best point for radial artery puncture, and the position is clinically used as the radial artery puncture point, so the position of the puncture point is relatively fixed. Therefore, the pressing member 230 is disposed at a position corresponding thereto, and can be applied to the pressing of the puncture site of most patients.

Preferably, the compression member 230 may be provided with a hemostatic dressing for wound healing on a side thereof remote from the adjustment member 220, which may be provided with thromboxane for promoting blood clotting, accelerating hemostasis and reducing bleeding risk, and providing a suitable moist environment for the wound surface for wound healing.

The following explains the specific steps of the utility model in combination with the working principle:

when the device of the present utility model is worn by a patient, the patient first stretches his/her hand, which is left after the radial artery coronary intervention, into the wristband 210 and the palmar sleeve 110 with the aid of medical staff, and then adjusts the angle and position of the hand so that the compression member 230 can face the hemostasis point of the user. After the adjustment, the adjusting member 220 is adjusted to enable the pressing member 230 to press towards the position of the hemostatic point and apply a certain pressure, and in addition, as the hemostatic dressing is coated on the pressing member 230 in advance, the pressing member can enable the wound to absorb the hemostatic dressing in an accelerating way, so that the wound healing is facilitated. The proximal end of the first restriction member 310, which is connected to the compression member 230, also provides a greater restriction force than the distal end during adjustment of the adjustment member 220 to compress against the hemostatic site, avoiding tearing and bleeding of the skin tissue at the hemostatic site of the patient. After the adjustment of the adjustment member 220 is completed, the patient may twist his or her finger slightly and then may apply the finger cuff 120 to the tip of his or her finger and assist in securing the finger cuff 120 with a securing strap. After the fingerstall 120 is worn, the length of the elastic piece 130 is shorter than that of the finger of the patient, so that the patient can play a role in rehabilitation training on the finger under the elastic action of the elastic piece 130 through the contraction and extension movements of the finger.
