[0025] In order to make the technical solution of the present invention better understood by the technical personnel in the field, and to make the above-mentioned features, purposes and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the embodiments. The embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1-2 As shown, the utility model comprises: a connecting plate 1, the connecting plate 1 is fixed to the patient bed;

[0027] A fixed column 2 detachably connected to the connecting plate 1, the fixed column 2 comprising an adjusting column 21 and a fixed base 22 which are connected in a limited position, the adjusting column 21 being connected in a limited position to the fixed base 22 and being fixedly connected to the connecting plate 1 through the fixed base 22;

[0028] The fixed handle 3 is sleeved on the outside of the fixed column 2. The fixed handle 3 is divided into a waterproof layer, a deformation layer and a shaping layer from the outside to the inside. One side of the fixed handle 3 is provided with a wave shape matching the patient's hand after gripping.

[0029] Before use, the fixed column 2 and the connecting plate 1 are limited and fixed, and then the fixed handle 3 is first put on the outside of the fixed column 2, and finally the position of the patient's bed is selected to fix the connecting plate 1 to the patient's bed. Generally, the specific position is selected according to the functional position of the patient's hands constrained on both sides of the body.

[0030] After the patient's radial artery is cannulated, the patient places his hands on one side of the fixed handle 3, and the functional positions of both hands are restrained on both sides of the body. In this fixed posture, it can be ensured that the fluctuation of the patient's radial artery can be effectively and without interference received by the invasive arterial pressure sensor.

[0031] Several ways to fix the connecting plate 1 to the patient bed board

[0032] First, the connecting plate 1 is also provided with a fixing clip, which is fixed to the patient's bed through the fixing clip. The operation is simple and can be reused, but it is easy to move due to external factors.

[0033] Second: If Figure 1 As shown in , a bolt group is provided on the connecting plate 1, which is fixed to the patient bed by bolt connection. The operation is complicated and needs to be installed every time, but it can be reused and is not easily moved due to external factors;

[0034] Third: an adhesive layer is provided at the bottom of the connecting plate 1, which is fixed to the patient's bed by bonding. It is easy to operate and not easily moved due to external factors. However, it cannot be reused and is more troublesome to clean. It is only suitable for removal after installation and is only suitable for people of general height and weight.

[0035] In order to accommodate patients with different physical conditions, the angle between the fixing column 2 and the connecting plate 1 is 70° to 90°.

[0036] The fixing base 22 is fixedly connected to the connecting plate 1 by bonding or bolting. In this embodiment, the bonding method is glue.

[0037] like Figure 2 As shown, a circular arc-shaped moving groove 221 is opened on the top of the fixed base 22, and a plurality of corresponding limiting holes 222 are arranged on both sides of the moving groove 221, and a fixing rod is arranged in the limiting hole 222;

[0038] The bottom of the adjusting column 21 is connected to the bottom of the moving groove 221 through a rotating shaft, and a positioning hole 211 corresponding to the limiting hole 222 is opened at the center of the adjusting column 21.

[0039] The angle between the fixing column 2 and the connecting plate 1 is adjusted by rotating the adjusting column 21 around the rotating shaft. After selecting a suitable angle, the fixing rod is passed through the limiting hole 222 on one side, the positioning hole 211, and the limiting hole 222 on the other side in sequence to fix the adjusting column 21. In order to prevent the adjusting column 21 from being pushed out due to external factors, one end of the fixing rod can be further fixed to the limiting hole 222 by means of a thread.

[0040] like Figure 3As shown in the figure, as the specific structure of the fixed handle 3: the waterproof layer is waterproof leather, the deformation layer is sponge, and the shaping layer is a silicone model. The deformation layer cannot be too thick and is generally controlled at 0.5-1cm. The thickness of the shaping layer is less than 0.4cm, which means that it can be deformed to a certain extent, and will not cause shaking due to deformation. In order to better fix, the fixing column 2 is wide at the top and narrow at the bottom, and the shape of the inner cavity of the fixed handle 3 corresponds to the shape of the fixing column 2.

[0041] The above embodiments are merely illustrative of the principles and effects of this patent application, and are not intended to limit this patent application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
