[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0022] The specific embodiment of the utility model provides a special body position pad for radial artery puncture, combined with the attached Figure 1 As shown, it mainly includes a base 1, a bionic protrusion 2, a fixing part 3 and an attachment layer 4, wherein the bionic protrusion 2 and the fixing part 3 are both arranged on the base 1, and the top shape of the bionic protrusion 2 along the length direction of the base 1 is an arch shape formed when the forearm and the back of the hand are bent toward each other. The arch shape formed when the wrist is bent toward the back of the hand is adopted to ensure that the patient's wrist can be arched after being placed on the bionic protrusion 2, which is convenient for medical staff to perform radial artery puncture. The fixing part 3 is arranged on the base 1 on the side of the bionic protrusion 2 close to the back of the hand, and the position of the patient's hand is fixed by the fixing part 3 to prevent the movement of the patient's hand during the puncture from affecting the puncture. The attachment layer 4 is arranged on the upper end surface of the whole formed by the base 1 and the bionic protrusion 2. The attachment layer 4 is the part in contact with the patient's skin and can be made of skin-friendly material. The use of the above-mentioned special positioning pad for radial artery puncture can provide effective and stable support for the patient's wrist during radial artery puncture, avoiding the risk of puncture due to collapse of the support body.
[0023] The bionic protrusion 2 in the present application is integrally formed of a soft material, for example, the bionic protrusion 2 can be made of silicone material.
[0024] In a specific embodiment of the present application, the length of the bionic protrusion 2 in the direction perpendicular to the length of the base 1 is longer than the length of the base 1, so that the bionic protrusion 2 can ensure complete support for the patient's arm and can also extend on both sides of the patient's arm, wherein the attachment layer 4 is made of an absorbent material, so that the attachment layer 4 has the ability to absorb liquid, and the upper end surface of the whole formed by the attachment layer 4, the base 1 and the bionic protrusion 2 is detachable. Bleeding is prone to occur during radial artery puncture. The wider bionic protrusion 2 and the detachable attachment layer 4 with blood absorption ability are used to absorb the blood that appears during the puncture process. The attachment layer 4 is replaced before each puncture to ensure that the radial artery puncture is completed in a clean environment to avoid cross infection.
[0025] The specific attachment layer 4 can be a disposable pad, for example, a disposable medical pad paper, a disposable medical pad, etc.
[0026] In the specific embodiment of the present application, the top shape of the bionic protrusion 2 along the direction perpendicular to the length of the base 1 is designed to be a radial bionic shape of the forearm and the back of the hand. In this way, the upper end surface of the bionic protrusion 2 forms a bionic shape with a depression in the middle and protrusions at both ends along the direction perpendicular to the length of the base 1. At this time, when the patient places the wrist inside it, it can play a good supporting effect and at the same time can avoid the movement of the wrist position to a certain extent.
[0027] In a specific embodiment of the present application, an anti-slip portion may be provided at the bottom of the base 1 , and the anti-slip portion may be a protrusion made of a material with greater friction, such as rubber.
[0028] The base 1 can also be made of a material with high friction such as rubber, so that when the base 1 is placed on a desktop, there will be high friction between the base 1 and the desktop.
[0029] In a specific embodiment of the present application, the bionic protrusion 2 can also be designed as a structure combining an outer coat and a filler, wherein the outer coat is supported by an elastic material, the filler is filled inside the outer coat, and the filler is a soft material. The contour shape of the bionic protrusion 2 is located on the upper end surface of the filler, and a placement hole is provided on the outer coat, through which the filler can be placed inside the outer coat. In this way, the wrist shape of different people can be adapted by fillers with different contour shapes inside, so as to achieve the best support effect for the patient's wrist.
[0030] The fixing part 3 in the present application can be designed as a strap, one end of which is connected to one side of the base 1, and the other end of the strap is detachably connected to the other side of the base 1, so as to achieve good fixation of the patient's hand position through the strap.
[0031] In the present utility model, the terms "one embodiment", "some embodiments", "examples", "specific examples", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present utility model.

Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
