[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In an exemplary implementation, such as Figure 1-3As shown, this embodiment provides an arm infusion protection device, which includes a base plate 1 and an arched plate 2 detachably connected to the base plate 1 and forming an arched channel. The connection between the base plate 1 and the arched plate 2 can adopt the connection method in the prior art, such as the connection method in the applicant's previous application (patent publication number CN222566455U). Alternatively, one side of the arched plate 2 can be connected to one side of the base plate 1 by a hinge, and the other side can be connected by a snap-fit ​​method. The main advantage is that the detachable structure facilitates operations such as needle insertion and removal. Furthermore, compared with the prior art, the improvement of this solution lies in that the base plate 1 is respectively connected to the arched plate 2. The first fixing strap 3 and the second fixing strap 4 outside the channel are used to position the arm. Both the first fixing strap 3 and the second fixing strap 4 include a flexible strap 5 and Velcro female and Velcro female straps 6 and 7 fixed to opposite ends of the flexible strap 5. This allows for easy adjustment of tightness, avoiding discomfort caused by prolonged elastic wear and solving the problem of arm discomfort caused by using straps to position the arm within an arched channel in existing technologies. Furthermore, this solution also includes a pair of elastic pads 8 fixedly connected to the base plate 1 at both ends within the arched channel. These elastic pads 8 provide support for the arm within the arched channel. To provide elastic support and improve arm comfort, more specifically, the base plate 1 is provided with several first through holes 9, and the arched plate 2 is provided with several second through holes 10. All the first through holes 9 are located between two elastic pads 8. The first through holes 9 and the second through holes 10 connect the inside and outside of the arched channel in the vertical direction, thereby preventing stuffiness around the arm during infusion. In another embodiment, a heat preservation device, such as a heat preservation blanket or an electric blanket, can be installed between the two elastic pads 8. This allows the arched channel to be heated and maintained at a constant temperature during infusion in winter, preventing the arm from getting cold and uncomfortable. In a further embodiment, on both sides of the arched plate 2... A hook 11 is also fixedly installed on the inner wall. The hook 11 can be similar to that in the prior art (patent announcement number CN222566455U) and is used to position and lock the infusion tube to prevent the infusion tube from shaking in the arched channel. In a further embodiment, the flexible band 5 does not have to be made of elastic material. As long as it can bend and deform smoothly, it can wrap around the arm, so that the Velcro 7 can be smoothly connected to the Velcro 6 without causing elastic pressure on the arm, which has better comfort. More specifically, the length of the Velcro 6 is greater than the length of the Velcro 7, which has better adaptability to tightness adjustment when connected.

[0025] like Figure 1-3As shown, in this scheme, the flexible strips 5 of the first fixing strip 3 and the second fixing strip 4 are respectively fixed to the base plate 1 by the connecting strip 13. Specifically, the connecting strip 13 is fixedly connected to the middle section of the flexible strip 5, and the connecting strip 13 extends into the arched channel. It is pressed onto the base plate 1 by the pressure plate 14. The pressure plate 14, the connecting strip 13, and the base plate 1 are connected by screws 15. This creates a gap between the first fixing strip 3 and the second fixing strip 4 and the two ends of the arched channel, allowing the infusion tubing to enter the arched channel. At the same time, the first fixing strip 3 and the second fixing strip 4 are detachable. The design allows for easy storage when not in use. More specifically, the top surface of the screw 15 is located below the upper surface of the pressure plate 14, which avoids the screw 15 causing discomfort to the arm. Furthermore, the top surface of the elastic pad 8 can be higher than the pressure plate 14, which can better prevent the arm from being affected by the screw 15 and causing discomfort. On the other hand, the connecting strap 13 and the base plate 1 can also adopt other detachable connection methods, such as snap fastening (a male buckle is set on the base plate 1, and a female buckle that mates with the male buckle is set on the connecting strap 13, and the two can be fastened together).

[0026] like Figure 1-4 As shown, in a further embodiment, the elastic pad 8 is also fixedly connected to the arc-shaped wing plates 16 located at both ends and extending upwards. The elastic pad 8 mainly provides cushioning support (it can be made of rubber), and at the same time, it prevents the part of the arm located between the two elastic pads 8 from being tightly pressed against the inner bottom surface of the base plate 1, so that the first through hole 9 below can connect the inside and outside. At the same time, the bottom surfaces of the base plate 1 are also fixedly connected to the pad blocks 12, which raises the bottom of the base plate 1 and ensures that the first through hole 9 connects the inside and outside. Furthermore, the elastic pad 8 is also fixedly connected to the arc-shaped wing plates 16 located at both ends and extending upwards. The arc-shaped wing plates 16 and the elastic pad 8 can be made of rubber as a single structure, making the whole U-shaped, providing a certain left and right limit for the arm. A sponge layer (or cotton cloth, cotton, etc.) can also be set on the inner wall of the single rubber material to provide further cushioning.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
