With the development of the economy in our country,trauma has already become a major medical burden in society,traffic injury has already become a major type of trauma,and the trauma of lower limbs is relatively much more.Since patients with lower extremity trauma have limited mobility,postoperative dressing changes need to be done at the bedside.At present,in the process of lower limb dressing change,it is necessary for family members or medical staff to help elevate the affected limb,which is unstable and difficult to adhere to.The dressing change process not only increases the pain of patients,but also affects the sight line and comfort of medical staff during operation,resulting in incomplete wound exposure and affecting the effect of dressing change.The washing solution and disinfectant in the dressing change process are easy to contaminate the sheets,which increases the difficulty of ward management.This dressing change method is unscientific,irregular and inconvenient to operate.Therefore,the medical staff of department of emergency of the First Hospital of Jiaxing City developed a mobile treatment vehicle for leg care for debridement and dressing change of patients with lower limb trauma,this device has been granted the National Utility Model Patent of China(patent numbeer:ZL 2021 2 0647636.0),which makes bedside debridement and dressing change more scientific,convenient and normative.The utility model relates to a mobile treatment vehicle for leg care,which is composed of a base,a support seat,a leg support plate,a support rod,a fixed plate and a smart trash can.The angle of the leg support plate can be adjusted 360 °by loosening the bolt,and the height can be adjusted by sliding up and down.Adequate rotation flexibility and high adjustment space can effectively solve problems of bedside debridement and dressing change for patients with lower limb trauma,provide scientific,simple and operable auxiliary tools for trauma medical staff,improve the comfort of patients and operators,and improve the quality of ward management in emergency trauma ward.

Non-invasive mechanical ventilation(NIV)is increasingly being used as a respiratory support technique in clinical practice.However,the pressure-related injuries should not be overlooked.In order to prevent local pressure injuries caused by NIV technology,a series of preventive measures have been adopted in clinical work.These measures include the use of dressings to provide pressure relief to the local skin.Currently,in clinical practice,when using preventive dressings,nurses need to cut them themselves based on the physiological structure of the patient's nose,forehead,or face.However,precise cutting can be challenging.If the dressing is cut too small,it may not provide adequate prevention,and if it's cut too large,it can cover too much skin,affecting the nurse's observation and the patient's comfort.Additionally,during NIV treatment,the preventive dressings used may become curled or displaced,requiring nurses to re-cut and replace them.This process inevitably leads to material wastage,increasing the cost of dressing use for patients.Moreover,the cutting tools used must meet infection control requirements,adding to the nursing workload and reducing the compliance of nurses in changing dressings.Our research team has designed a ready-made pressure injury prevention dressing component for use with NIV masks to prevent pressure injuries to the nasal and facial areas.It is precisely designed,flexible in composition,easy to use,and can provide multiple usage modes.It effectively combines emergency care with pressure relief measures,reducing the occurrence of pressure injuries to the patient's nasal and facial areas.This improves patient comfort and treatment compliance,facilitates technology-based nursing,and enhances clinical efficiency.It has significant clinical application value and has been granted a National Utility Model Patent(ZL 202020529121.6).
