[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figure 1-3 The present application provides the following technical scheme: an inflatable arm type fixing plate, comprising a plate 1 and a bandage 2 arranged on the plate 1, the plate 1 comprising a palm plate 11, a small arm plate 12 and a large arm plate 13 rotatably connected at the head and tail, and a locking piece 3 arranged at each rotatable connection.

[0024] As an optional implementation scheme of the present invention, the plates 1 are rotatably connected to each other so that the fixing plate can be stored in a folded position when not in use, thereby reducing storage space and the probability of damage during transportation and storage. When in use, it can be directly unfolded and worn on the patient's arm in a posture that matches the patient's catheterization and puncture, taking into account the palm, forearm and upper arm, and the entire plate 1 is fixed with a locking member 3. The strap 2 therein can also be used to assist in fixing the catheter. Overall, it can prevent the arterial catheters in multiple parts of the patient's arm, such as the radial / brachial artery, from moving. After wearing, the design of the strap 2 will not cover the patient's catheterization site, making it convenient for medical staff to observe the catheterization situation.

[0025] In the present technical solution, the locking member 3 refers to a structure that can adjust the angles of the rotatably connected panels 1 and then fix them. There are many ways to achieve this technical purpose in the prior art, such as snaps, knob screws, etc. The present locking member 3 does not make specific restrictions on the specific implementation method. It should be understood that as long as the method can achieve the fixation of two rotatably connected panels 1, it is considered to be within the protection scope of the present technical solution.

[0026] Compared with the existing technology that only fixes the wrist to the palm end through an integrated plate 1, this fixing plate is easy to store when not in use due to the above structure. When in use, it only needs to be unfolded, worn on the arm and fixed. It can take into account the catheterization of the patient's entire arm at the same time, and can also be flexibly adjusted according to the patient's actual arm posture. It is ergonomic and convenient for subsequent catheterization observation.

[0027] like Figure 1 and Figure 3 As shown, the axis positions of the two rotating connections correspond to the wrist joint and the elbow joint respectively, and the axis directions are perpendicular to the planes of each plate 1.

[0028] As an optional implementation scheme of the present invention, since the catheterization operation is usually performed on the inner side of the arm where the skin is more tender and the blood vessels are more abundant, and the entire fixing plate is connected to the back of the hand, the plate 1 is usually placed on the outside of the arm. The parallel rotation of each plate 1 not only meets the basic requirement of exposing the inner side of the arm for catheterization observation and operation, but also makes the adjustment more flexible and convenient for matching the bending and stretching posture of the patient's arm. The entire plate 1 is more ergonomic. Secondly, the entire fixing plate has only a single rotation method. Compared with the folding method, it makes it less likely for the patient to bend the arm toward the torso after wearing it, and can better avoid bleeding, hematoma, pseudoaneurysm, etc. at the puncture site. It is also convenient to keep the catheterization position in an exposed posture for easy observation.

[0029] like Figure 2As shown, the locking member 3 includes a nut 31 and a washer 33 , and the end of each plate 1 is respectively provided with a stud 32 threadedly engaged with the nut 31 and / or a through hole for the stud 32 to pass through.

[0030] As an optional implementation scheme of the present invention, the nut 31 plus the gasket 33 is a common way of adjusting the screw. When the wearing is completed, the fixation of each plate 1 can be completed by directly tightening the nut 31.

[0031] like Figure 2-3 As shown, each stud 32 is fixedly connected to the plate 1. An integrally formed connection is preferred to enhance the strength of the entire fixing plate.

[0032] like Figure 1-2 As shown, each plate 1 is provided with a plurality of ventilation holes 1a to facilitate ventilation of the patient's arm skin and avoid the breeding of prickly heat and the like.

[0033] like Figure 3 As shown, each plate 1 is made of a hard material and is covered with a breathable fabric 4. The hard plate 1 is relatively strong, which helps to improve the fixation effect of the entire fixation plate on the patient's arm posture after wearing it. The breathable fabric 4 improves the comfort of the entire fixation plate after wearing it, avoiding strong discomfort caused by prolonged wear.

[0034] like Figure 3 As shown, the surface of the strap 2 is provided with Velcro 5, and each plate 1 is provided with a connecting portion 6 for installing the strap 2. The connecting portion 6 includes one of a perforation and a buckle. An inflatable airbag 7 is also provided on the inner side of the strap 2 located on the upper arm plate 13.

[0035] As an optional embodiment of the present invention, the strap 2 and Velcro 5 are common wearing methods and will not be described in detail here. Regarding the inflatable airbag 7, its main function is to increase its volume after inflation, which can improve the support and comfort of the inner side of the patient's upper arm. Since the patient rests in bed for a long time during the intubation, the upper arm is unsupported and suspended. The entire plate 1 plus the intubation has a certain weight, so the use of the airbag 7 can make the suspended upper arm more comfortable.

[0036] The working principle and use process of the present invention are as follows: after puncture and catheterization, the fixing plate is taken out and directly unfolded. After wearing, the rotation angle between each plate 1 is adjusted according to the curvature and extension of the patient's arm, and finally the nut 31 is tightened.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
