[0002] Arterial catheterization refers to arterial puncture catheterization, which is often used to establish a drug infusion channel, draw arterial blood samples or perform surgical tests. Arterial puncture catheterization is generally used to monitor various critically ill patients, such as patients with severe shock, cardiopulmonary failure, etc. It is to repeatedly draw arterial blood samples for blood gas analysis or electrolyte determination, thereby detecting real-time blood pressure, repeatedly collecting blood gas, and alleviating patient pain. Arterial catheterization usually requires padding under the wrist and letting the palm tilt downward to fully expose the position of the artery to ensure smooth catheterization. The Chinese utility model patent with application number 202121398305.4 discloses a radial artery catheterization handrest cart, which has a cushioning mechanism on the right side of the upper surface of the handrest. The cushioning mechanism can be used to raise the patient's wrist, and the position of the cushion can be adjusted by the first slider and the first connecting rod, and the first limit knob is used to limit and fix it.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0031] like Figures 1 to 4 As shown, a sterile arterial catheterization adjustable pillow comprises an inflatable body 1, which is a trapezoidal structure with a small upper part and a large lower part. The interior of the inflatable body 1 is divided into several layers by a transverse partition membrane 2. A vent hole 21 (circular in this embodiment) is embedded in the center of each layer of the partition membrane 2. The front and rear sides of the vent hole 21 are bonded with overlapping valves 22 (after the pressure reaches a certain value, the gas can pass through the valve 22 to enter the next layer). A deflated inflatable structure 3 is provided on the right side of the bottom layer. A sterile towel bag 4 is provided on the bottom surface of the inflatable body 1. The left end of the sterile towel bag 4 is bonded and fixed to the bottom surface of the inflatable body 1. A notch 41 in the front-to-back direction is provided on the lower part of the sterile towel bag 4. A sterile towel 5 is placed in the sterile bag 4 in the notch 41. One end of the sterile towel 5 is fixedly connected to the sterile towel bag 4 inside the notch 41. A through hole 51 (circular in this embodiment) is provided at the center of the sterile towel 5.

[0032] The inflatable structure 3 includes an inflatable tube 31, the left end of which is connected to the inner part of the bottom layer of the inflatable body 1, and the right end of which is connected to the outlet nozzle (not shown) of the inflatable balloon 32, and the other side of the inflatable balloon 32 is provided with an inlet nozzle 321. A three-way valve 33 is also provided on the inflatable tube 31.

[0033] A one-way valve is provided in the air outlet of the inflatable balloon 32 to allow only air to escape.

[0034] A one-way valve that only allows air to enter is disposed in the air inlet nozzle 321 of the inflation balloon 32 .

[0035] The notch 41 is located at the left end of the lower part of the sterile towel bag 4. After the sterile towel bag 4 is turned out, the notch 41 is close to the inflatable body 1, which is convenient for the sterile towel 5 to be pulled out close to the inflatable body 1, thereby facilitating the operation of the staff.

[0036] The vertical projection area of ​​the sterile towel bag 4 is the same as the vertical projection area of ​​the bottom layer of the inflatable body 1 .

[0037] When in use, the inflatable body 1 can be inflated through the inflatable structure 3. When the lower layer is inflated, the inflated gas will not flow to the upper layer, ensuring that after the lower layer is filled with gas, the upper layer can be inflated only when the pressure is sufficient to squeeze open the overlapping part of the valve 22. At the same time, the purpose of adjusting the height of the trapezoidal inflatable body 1 is also achieved. Adjust the three-way valve 33 ( Figure 3 90 degrees to the left) so that the inflation tube 31 is connected to the inflation balloon 32, and the inflation body 1 can be inflated by pressing the inflation balloon 32; adjust the three-way valve 33 ( Figure 3 The left inflation tube 31 is connected to the side opening of the three-way valve 33, and the inflation body 1 is squeezed to deflate. The sterile towel bag 4 at the bottom is folded to the left, and then the sterile towel 5 is pulled out from the notch 41 and laid on the patient's wrist, so that the through hole 51 is located at the puncture site of the wrist, thereby establishing a sterile environment for puncture. Example 2

[0038] The left and right sides of the uppermost layer of the inflatable body 1 are respectively provided with hooks of fasteners (not shown), and the bottom surfaces of the left and right sides of the central through hole 51 of the sterile towel 5 are respectively provided with hooks of fasteners (not shown). The cooperation between the hooks of fasteners and the hooks of fasteners can fix the sterile towel 5, prevent the sterile towel 5 from slipping off the wrist, and facilitate the accuracy of puncture by the staff. Example 3

[0039] like Figure 5 As shown, flexible limiting structures are respectively provided on the left and right sides of the top surface of the inflatable body 1.

[0040] The limiting structure is a semi-cylindrical sponge block 6 in the front-to-back direction, and the plane at the bottom of the sponge block 6 is bonded and fixed to the upper surface of the inflatable body 1 .

[0041] When in use, the sponge block 6 can limit the wrist on both sides to prevent slipping, which is further beneficial to the staff's arterial catheterization operation.
