Medical immobilization tape is a commonly used medical material in clinical practice, and the specific method of use should be analyzed in relation to the purpose of using medical immobilization tape. The purpose of the medical immobilization belt is to fix the patient area, reduce the movement of the patient area, so as to improve the local pain situation, but also conducive to the recovery of the patient. Commonly used medical immobilization straps include: wrist brace, elbow brace, bunion fixation set, forearm fixation set, chest immobilization strap and so on. Taking chest immobilization belt as an example, it is mainly used for the treatment and recovery of patients with rib fracture. Due to the special anatomical nature of the rib cage of the thorax, which is curved, there is a certain degree of difficulty in ordinary fixation methods. Medical immobilization straps can be used, which can limit the undulating activities of the thorax and reduce the friction of the broken end of the rib, thus improving the local pain. During use, the chest fixation belt needs to be wrapped around the chest for fixation, and the fixation belt should be tightened appropriately, but not too tight, so that the patient can breathe freely. As the rib fracture slowly recovers, the chest immobilization band can be removed as appropriate.
