Description

TECHNICAL FIELD

[0001] The present application relates to a tracheostomy post-protection device. BACKGROUND

[0002] Tracheostomy is an important means to relieve airway obstruction and maintain respiratory patency in clinical practice, and plays a key role in the treatment of critically ill patients. After the operation, in order to prevent foreign matter from entering the airway and reduce the risk of infection, the tracheostomy site of the patient usually needs to wear a special protective device.

[0003] The tracheostomy post-protection device in the prior art is generally composed of a cover body connected to the tracheostomy site of the patient and a filter screen arranged in the cover body. The main function of the filter screen is to filter the air entering the airway and block harmful substances such as dust, bacteria and droplets in the air, thereby reducing the infection rate.

[0004] However, in actual use, when it is necessary to perform sputum suction, dressing change and other operations on the patient, the cover body of the protective device needs to be removed from the base. At this time, the filter screen in the cover body is directly exposed to the external environment. Since the existing protective device lacks a protective structure specially designed for the filter screen in the dismounted state, the filter screen is easily contaminated during the standby process. Specifically, airborne bacteria and dust particles will adhere to the filter screen in large quantities.

[0005] These contaminations not only reduce the filtering efficiency of the filter screen, but more seriously, when the cover body is installed back to the base again, the contaminants on the filter screen will enter the tracheostomy site with the patient's breathing, thereby significantly increasing the risk of surgical wound infection, adversely affecting the postoperative recovery of the patient, and even causing serious complications, increasing the probability of surgical wound infection, prolonging the hospitalization time of the patient and increasing the treatment cost.
