Description

Technical Field

[0001] This invention relates to the field of auxiliary support device technology, specifically to an auxiliary support device for postoperative coughing in elderly patients undergoing thoracic surgery. Background Technology

[0002] In thoracic surgery, difficulty coughing up sputum is a very common postoperative complication in elderly patients due to declining physical function, postoperative wound pain, and weakened muscle strength. Thoracic surgeries (such as radical resection of lung cancer and esophagectomy) cause trauma to the patient's chest tissues. When patients cough up sputum after surgery, the contraction of chest muscles pulls on the wound, causing severe pain. This leads patients to consciously suppress the coughing action, resulting in sputum accumulation in the airway. This not only affects lung ventilation but may also induce serious complications such as lung infection and atelectasis, significantly prolonging the patient's hospital stay and increasing the risk of postoperative recovery.

[0003] To alleviate postoperative coughing difficulties in elderly patients, current clinical practice often employs manual coughing assistance or simple assistive devices. Manual coughing primarily involves medical staff or family members manually pressing on the patient's chest to assist pectoral muscle contraction and promote sputum expectoration. The pressure applied relies entirely on experience; excessive force can worsen wound damage, while insufficient force fails to provide effective assistance. Furthermore, manual pressure requires continuous application of force, leading to high workload for medical staff and inconsistent operational procedures by family members, resulting in inconsistent effectiveness. Additionally, patients experience wound pain during coughing, and sputum expectoration is inefficient. While some compression-type assistive devices provide external pressure, the pressure adjustment is imprecise, and their rigid connection structure results in poor fit to the patient's chest, potentially causing localized pressure injuries. Moreover, they are not suitable for the different body types of elderly patients. Furthermore, patients need to use sputum cups and other instruments when coughing up sputum, which is inconvenient to operate, and sputum is prone to splashing, causing environmental pollution and increasing the risk of cross-infection. At the same time, elderly patients often need nebulization therapy after surgery to dilute sputum. After nebulization therapy, patients need to switch to sputum-clearing aids, which is a complicated procedure that increases the burden of postoperative activity and is not conducive to rapid recovery.

[0004] In summary, a postoperative cough support device for elderly thoracic surgery patients is needed to address the aforementioned issues. Summary of the Invention
