Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a fixing device for the affected limb in the treatment of upper limb fractures. Background Art

[0002] The neck-wrist suspension sling is a commonly used fixing tool after upper limb fractures or dislocations at present. It is mainly used for the suspension-assisted treatment usually required for patients with forearm fracture injuries during reduction or after surgery. At present, the suspension force of the neck-wrist suspension sling is concentrated on the neck, and the suspension points are on the affected limb and the neck. When the suspension points are used as fulcrums, they are unstable, and the passive movement of the upper limb during body activities is a shortcoming that cannot be overcome by this suspension method. Summary of the Invention

Detailed Embodiments

[0020] The present invention will be further described below in conjunction with specific drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the scope of protection of the present invention.

[0021] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0022] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0023] As Figure 1 , Figure 2 shown, the embodiment discloses a fixing device for the affected limb in the treatment of upper limb fractures, which mainly consists of components such as an arm support 1, a restraint strap 2, a waist binding strap 3, a shoulder cross strap 4, etc.

[0024] The arm support 1 is the main body for supporting and fixing the affected limb. Along the length direction of the upper surface of the arm support 1, there is a groove for placing the arm. Several pairs of restraint straps 2 are installed on both sides of the groove for placing the arm. When the arm is placed in the groove for placing the arm, it can be reliably fixed. Both ends of the arm support 1 are respectively connected to the waist binding strap 3 through an adjustable connection device that can finely adjust the connection position vertically. The waist binding strap 3 is used to fix the arm support 1 on the side of the patient's waist. Since the individual conditions of patients and the injury conditions of the arms are different, the fixed positions of the arms after surgery are also different. In order to ensure that the arm can be stably and reliably supported, the present application specially designs an adjustable connection device. By operating the adjustable connection device, the connection position between the waist binding strap 3 and the end of the arm support 1 can be vertically finely adjusted, so that the arm can be firmly supported at multiple positions [such as positions with the front higher than the back, the front lower than the back, etc.]. In addition, a shoulder cross strap 4 with an adjustable overall length is installed on the waist binding strap 3. When the shoulder cross strap 4 is used, it is worn obliquely on the shoulder, making the fixation of the arm support 1 more secure, and the patient's shoulder and waist bear the force together, with comfortable use.

[0025] In this embodiment, the adjustable connection device includes a fine adjustment screw rod 5 and a flat joint 6 with an internal threaded hole. Installation notches 1a are provided on the near-body sides of both ends of the arm support 1. The fine adjustment screw rod 5 is vertically installed at the installation notch 1a at the end of the arm support 1, and the upper end of the fine adjustment screw rod 5 is exposed for screwing. The flat joint 6 is threadedly installed on the part of the fine adjustment screw rod 5 located within the installation notch 1a, and the end of the waist binding strap 3 is connected to the flat joint 6. With such a setting, by screwing the fine adjustment screw rod 5 forward and backward, the flat joint 6 can move up and down along the fine adjustment screw rod 5 to achieve fine adjustment of the connection position.

[0026] In this embodiment, the surface of the arm placement groove is covered with a breathable soft cushion 7, which is preferably made of latex material provided with breathable holes, so as to further improve the comfort of the patient during the rehabilitation treatment.

[0027] In this embodiment, the waist strap 3 includes two elastic bands 31 and a set of docking buckles 32. One ends of the two elastic bands 31 are respectively connected to the two ends of the armrest 1, and the other ends of the two elastic bands 31 are installed with the docking buckles 32. The shoulder sling 4 includes a non-elastic flat belt 41, a threading head 42 and a snap button 43. One end of the non-elastic flat belt 41 is provided with a circular flat buckle, which is movably connected to one of the elastic bands 31, the threading head 42 is movably installed on the other elastic band 31, the other end of the non-elastic flat belt 41 passes through the threading head 42, and the non-elastic flat belt 41 and the threading head 42 are installed with selectively docking snap buttons 43. With such a setting, the patient can flexibly adjust the overall length and connection position of the shoulder sling 4 during use to ensure that the armrest 1 is comfortably and stably fixed on the side of the patient's body, and further ensure that the affected limb of the patient is supported in the most comfortable position.

[0028] In this embodiment, both ends of the restraint belt 2 are respectively connected to both sides of the arm placement groove, and the other end of the restraint belt 2 is provided with a magic tape.

[0029] In this embodiment, a socket 1b is provided at the front end of the arm placement groove, and a pluggable and detachable palm exercise ball [a commercially available product, so it is not shown in the figure] is installed in the socket 1b. In this way, the patient can also use the palm exercise ball for hand function training during the rehabilitation period to ensure that the limb function does not degenerate; the palm exercise ball can be detached when not in use for exercise.

[0030] In this embodiment, the side of the armrest 1 close to the body is set as a concave arc shape, and such a structure of the armrest 1 is more in line with the ergonomic design and is more comfortable to use.

[0031] The above-described are only the preferred embodiments of the present invention, and the above specific embodiments are not limitations to the present invention. Within the scope of the technical idea of the present invention, various deformations and modifications can occur. Any retouching, modification or equivalent replacement made by those of ordinary skill in the art according to the above description shall fall within the scope protected by the present invention.
