[0028] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the utility model.

[0029] Example: Please refer to Figures 1 to 5 :

[0030] The utility model provides a blocking device for preventing arm sagging, comprising:

[0031] At least two fixing seats 101, a connecting rod 102 is fixedly connected between the two fixing seats 101; at least one connecting seat 201 is rotatably connected to the outer side of the connecting rod 102, and a flexible support frame 202 is fixedly connected to the connecting seat 201; the support frame 202 rotates at an angle of 0-90° with the connecting rod 102 as the axis through the connecting seat 201, and the support frame 202 is bent to form a support surface parallel to the plane where the fixing seats 101 are located, and the end of the support surface away from the fixing seat 101 is bent to form a blocking surface perpendicular to the fixing seat 101;

[0032] In another embodiment, the device only blocks the patient's arms or legs, the support frame 202 and the fixing seat 101 form a 90° angle, and the support frame 202 is bent to form an arc-shaped surface that fits the patient's arms or legs, thereby restricting the patient's arms or legs within the space formed by the support frame 202 and the fixing seat 101, thereby preventing the patient's arms or legs from leaving the plane of the operating table and drooping, and reducing the space occupied by the device when in use, thereby preventing interference to medical staff performing the operation.

[0033] Among them, Figure 1 and Figure 2 As shown, the upper end surface of the fixing seat 101 is a horizontal surface, and the lower end surface of the fixing seat 101 is an arc surface; the upper end surface of the fixing seat 101 contacts the patient's body and is set as a horizontal surface, which can increase the contact area between the upper end surface and the patient's body, reduce the pressure between the device and the patient's body, and avoid long-term use of the device causing pressure injuries to the patient's body; the lower end surface contacts the bed body and is set as an arc surface, which can reduce the contact area between the device and the bed body, thereby reducing friction and facilitating the insertion of the device between the patient's body and the bed body.

[0034] Among them, Figure 3As shown, a guide surface 103 is provided at one end of the fixing seat 101 away from the connecting rod 102; the angle between the guide surface 103 and the upper end surface of the fixing seat 101 is 0-45°; the guide surface 103 guides the device when the device is inserted between the patient's body and the bed, making the process of inserting the device more labor-saving.

[0035] Among them, Figure 2 and Figure 3 As shown, at least two fixing seats 101 are rotatably connected with a roller 104 via a rotating shaft, and the roller 104 and the fixing seat 101 rotate unidirectionally; the surface of the roller 104 is provided with friction grooves; the roller 104 rolls when the device is inserted under the patient, so that the friction grooves on its surface do not affect the insertion of the device; the roller 104 does not roll when the device is pulled out, and the friction between the device and the patient's body and the bed is increased through the friction grooves, so as to avoid the patient's unconscious movements and cause the device to fall out from under the patient.

[0036] Among them, Figure 3 As shown, there is damping between at least one connecting seat 201 and the connecting rod 102; through damping, the rotation between the connecting seat 201 and the connecting rod 102 is limited by force, and only when the force reaches a certain value will the connecting seat 201 rotate around the connecting rod 102 as the axis.

[0037] Among them, Figure 4 As shown, a limiting hole 203 is opened inside the connecting seat 201, and the limiting hole 203 is a screw hole; a limiting member 3 is inserted into the limiting hole 203, and the limiting member 3 is a screw; the height of the thread of the limiting member 3 is greater than the height of the thread of the limiting hole 203; by tightening or loosening the limiting member 3, the connecting seat 201 can be fixed or movable relative to the connecting rod 102.

[0038] Among them, Figure 5 As shown, the outer side of the support frame 202 is wrapped with a flexible cushion 4; the cushion 4 increases the contact area between the support frame 202 and the patient's limbs, and provides flexible support for the patient's limbs, thereby increasing the comfort of the device when used.

[0039] Among them, Figure 3 As shown, the two connecting seats 201 are connected to the connecting rod 102, and the connecting seats 201 slide along the axial direction of the connecting rod 102; the two ends of the support frame 202 are respectively fixedly connected to the two connecting seats 201; the position of the connecting seat 201 can be changed along the axial direction of the connecting rod 102, thereby changing the position of the two ends of the support frame 202, and at the same time, the support frame 202 is flexible, and the overall shape of the support frame 202 can be set by medical staff. For example, if the overall shape is a circular ring, it can be used to support the patient's head, etc., thereby increasing the applicability of the device.

[0040] Specific usage and function of this embodiment: When the utility model is used, the fixing seat 101 is inserted under the patient's body, and the fixing seat 101 is fixed by the weight of the patient's body to ensure that the fixing seat 101 will not overturn. According to the needs of use, such as the position of the patient's head and limbs, the shape of the flexible support frame 202 is determined, and the angle between the support frame 202 and the fixing seat 101 is adjusted. At the same time, the support frame 202 is bent so that the support frame 202 has a supporting surface parallel to the fixing seat 101, which is used to place the patient's limbs on the supporting surface of the support frame 202, and the patient's limbs are blocked by the blocking surface, which facilitates surgical operations on the limbs and prevents the limbs from leaving the plane of the operating table and sagging.
