[0028] Embodiment one:

[0029] Referring to Figures 1-3 A novel auxiliary pillow fixing device for arterial puncture blood sampling includes a pillow 1 and a wrist support mechanism 2. The pillow 1 is used for supporting the small arm of the human body. The wrist support mechanism 2 is installed on one side of the pillow 1 and is used for assisting the back bending and drooping of the human wrist within a certain angle range. Through the wrist support mechanism 2, the skin of the patient can be tightened, the radial artery can be straightened and fixed, the radial artery can be fully exposed, the pulsation can be clearer, and the success rate of radial artery puncture by an anesthesiologist in an operating room can be improved.

[0030] Referring to Figures 1-3 In further embodiments, the wrist support mechanism 2 includes a pad plate 21, a bending dynamic plate 22, a wrist pad 23, and a driving assembly 24. The pad plate 21 is fixed on the pillow 1. The bending dynamic plate 22 extends out of the pillow 1 and is rotationally connected to the pad plate 21 through a rotating shaft. The bending dynamic plate 22 can rotate only when subjected to an external force. The wrist pad 23 is fixed and laid on the pad plate 21 and the bending dynamic plate 22 through elastic bands or magic tapes. In the present embodiment, the bending dynamic plate 22 and the pad plate 21 are rotationally connected through an external force and utilize the principle of friction. This is prior art and will not be described in detail. The wrist pad 23 is preferably fixed through elastic bands. The driving assembly 24 is installed between the pillow 1 and the bending dynamic plate 22 and is used for driving the bending dynamic plate 22 to rotate. The side of the wrist pad 23 connected to the bending dynamic plate 22 can rotate and bend with the bending dynamic plate 22. The wrist pad 23 always maintains support for the palm of the human body to avoid suspension, thereby improving the comfort of the patient. The pad plate 21 within the range of the pillow 1 and the bending dynamic plate 22 are both provided with a binding assembly 3 to bind and fix the palm and the wrist part, thereby avoiding the movement of the wrist part of the human body as much as possible during the puncture process, thereby improving the work efficiency.

[0031] Further, the pillow 1 and the wrist pad 23 are both made of high-density sponge material, which is soft and not easy to be compressed, and can further improve the comfort and satisfaction of the patient during treatment. The rotation angle between the curved dynamic plate 22 and the horizontal plane is between 45° and 55°, which ensures that the patient's palm is in an inverted arch shape and in an over-extended position.

[0032] Further, the binding assembly 3 in the range of the cushion plate 21 on the pillow 1 includes two magic tapes, one end of each of the two magic tapes is fixed on the two opposite side walls of the pillow 1, and the other end is adhered to each other; the binding assembly 3 on the curved dynamic plate 22 includes two magic tapes, one end of each of the two magic tapes is fixed on the two opposite side walls of the curved dynamic plate 22, and the other end is adhered to each other. In this embodiment, the installation and use of the magic tape are prior art and will not be described in detail.

[0033] Referring to Figures 1-3 In further embodiments, the driving assembly 24 is symmetrically installed with two groups to ensure the stability of the rotation of the curved dynamic plate 22. The driving assembly 24 includes a micro electric cylinder 241, a connecting ear one 242, a transmission shaft one 243, a connecting ear two 244, and a transmission shaft two 245. The transmission shaft one 243 is installed on the outer side wall of the pillow 1. The connecting ear one 242 is rotationally connected with the transmission shaft one 243 and is fixedly installed on the bottom of the micro electric cylinder 241 by a bolt. The connecting ear two 244 is sleeved on the telescopic rod of the micro electric cylinder 241 and is fixed by a clamping bolt. The transmission shaft two 245 is integrally formed on the side wall of the curved dynamic plate 22 away from the cushion plate 21. The connecting ear two 244 is fixedly connected with the transmission shaft two 245. When fixing the wrist, the medical staff controls the rotation angle of the curved dynamic plate 22 by the extension and retraction of the micro electric cylinder 241, so as to curve the palm back to the most suitable position to completely expose the radial artery.

[0034] Referring to Figure 1 and Figure 3 A control member 4 is installed on the pillow 1. The control member 4 is a small processor and is connected with a control button. The control member 4 is signal-connected with the micro electric cylinder 241. The control member 4 can control the opening and closing of the micro electric cylinder 241 and the extension direction of the piston rod. This is prior art and will not be described in detail.

[0035] Referring to Figure 1 and Figure 3 In further embodiments, a recess 231 is formed on the wrist pad 23. The recess 231 is adapted to the human wrist and palm, which can further ensure the limitation of the human hand and reduce the possibility of movement during the puncture process. A silica gel protrusion 232 is adhered to the inner wall of the recess 231 for supporting the wrist, which ensures the curved state of the human wrist.

[0036] Embodiment two:

[0037] Referring to Figure 4The difference between the embodiment and the embodiment one is that the cushion plate 21, the bending dynamic plate 22 and the wrist pad 23 are detachably sleeved with a cotton cloth sleeve 5, specifically, a zipper is installed on the cotton cloth sleeve 5 to facilitate dismounting, a large area of magic tape is installed on the outer wall of one side of the cushion plate 21, and the magic tape is attached to the cotton cloth sleeve 5, which is detachable, convenient to clean and replace, can be repeatedly used and low in cost; meanwhile, the binding assembly 3 on the bending dynamic plate 22 comprises two magic tapes, one end of the two magic tapes is fixed on the two opposite side walls of the bending dynamic plate 22 respectively, and the other end is inserted into the cotton cloth sleeve 5 to be attached to each other.

[0038] The above is only the preferred embodiment of the present application, and is not any form and substantial limitation of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the present application, a number of improvements and supplements can be made, and these improvements and supplements should be considered as the protection range of the present application.
