Boom strap with arm slip prevention and reduced internal rotation

The present invention relates to a boom strap, and more particularly to a boom strap for preventing medical arm sliding and reducing the internal rotation of the upper limb for the purpose of fixing, braking or protecting the upper limb due to injury or surgery.

The conventional boom strap is shown in Fig. 1. The structure of the general boom strap (10) basically comprises a hanging bag (12) and a shoulder strap (14). The rear end of the hanging bag (12) is closed. The end (121) has a through hole (122) at the front end, and an opening (123) is arranged on the top of the two ends, and a ring member (124) is fixed on the left and right side walls of the front end opening (122). One end of the shoulder strap (14) is fixed to the closed end (121) of the hanging bag (12), and the other end is provided with a pair of magic felts (141), and the ends thereof are passed through the ring member (124). Thereby, the length of the shoulder strap (14) can be adjusted.

When worn, as shown in Figures 1a and 1b, the patient's affected limb is inserted through the top opening (123) of the sling (12), and the wrist extends from the front end opening (122) so that the elbow abuts The closed end (121) of the hanging bag (12); the rear end (or outer end) of the conventional shoulder strap (14) is fixed to the closed end (121) of the hanging bag (12), and the front end of the shoulder strap (14) is affected by The upper arm of the limb is turned to the back and the opposite side of the shoulder The neck junction is lowered to the chest and fixed to the ring member (124) on the other side of the top opening (123) of the sling (12) (as shown in Figures 1a and 1b).

As with the traditional boom strap (10) mentioned above, due to its construction, the arm will be restrained in the inner rotation and the inner position, and the patient must deliberately put the arm close to the chest, otherwise the hanging bag will gradually move backwards. Sliding causes the arm to slip forward and lose its fixed effect.

As shown in Fig. 1c, in order to improve the disadvantage that the arm is easily slipped forward when the conventional boom strap (10) is worn, some of the commercially available boom straps (10') are pierced at the front end of the hanging bag (12) (122). A small loop (125) is attached to the top to teach the patient to hook the thumb into the annulus (125) to prevent the hanging bag (12) from slipping off. However, in fact, when the patient hooks the thumb to the annulus for a long time, the thumb is very uncomfortable and prone to fatigue and soreness, and the anti-slip effect is often poor, so most patients do not use it and are ineffective. Moreover, the wearing method is the same as that of the traditional boom strap (10). Similarly, the arm will be restricted to the position of the inner rotation, and the inner rotation of the forearm is not conducive to the joint ligament tissue caused by the dislocation of the shoulder joint.
