Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a noninvasive ventilation fixing device. BACKGROUND

[0002] With the progress of science and technology, most invasive ventilators now have the function of "noninvasive ventilation", that is, CPAP mode. In view of the need of clinic: for the convenience of patients to switch ventilation modes, invasive-noninvasive mechanical ventilation sequential treatment, the invasive ventilator is often used for noninvasive ventilation in clinic.

[0003] The invasive ventilator has the following problems when used for noninvasive ventilation: 1. Although most invasive ventilators now have noninvasive ventilation mode, they do not have a special noninvasive mask; 2. The mask matched with the special noninvasive ventilator cannot be used for the invasive ventilator because of the air leakage device at the interface. Therefore, a disposable sealed anesthesia mask and a silica gel four-head belt are now often used for fixation, but there are the following disadvantages: ① The disposable sealed anesthesia mask has only a single tracheal interface, and the mask rim has no fixed socket, only four hooks at the tracheal joint are connected with the four-head silica gel fixing belt, which leads to uneven pressure at each part of the mask rim, and air leakage is prone to occur. Nurses often adopt the method of tightening the fixing belt to avoid air leakage, which increases the risk of skin pressure injury, causes discomfort of the patient due to tightness, and affects compliance. ② The four-head silica gel fixing belt has a small stress area and cannot be fixed on the head. When the patient turns over or subconsciously pulls the mask, the mask is prone to slide down, which leads to displacement of the mask, air leakage, formation of invalid oxygen supply, and affects the treatment effect. ③ After the four-head belt is untied, it is scattered on the pillow, which is inconvenient to wear. The patient's head needs to be lifted to arrange and wear the belt, and even two people are needed to operate, which is time-consuming and laborious and increases the nursing workload. The comfort degree of the connection interface is considered to be the most critical and independent risk factor for the success of noninvasive treatment. The sealing and stability of the connection have a great influence on the comfort and compliance of the patient. Therefore, in the process of using the noninvasive ventilator, how to improve the sealing effect of the mask and the comfort of the patient, and how to reduce the air leakage amount of the noninvasive ventilator mask are the keys to improving the success of noninvasive ventilator treatment.
