Breathing machine mask for severe cases

Abstract

The invention discloses a breathing machine mask for severe cases. The mask comprises a mask body, a connecting rod, a connecting plate, a fixing block, a lower bandage, a limiting block, a fixing rod, a fixing groove, a moving block, a moving plate, a first spring, a placing groove, a limiting groove, a rotating rod, a second spring, a push rod and a limiting rod. The mask is simple in structureand convenient to operate, the connecting rod is limited through the limiting block, the connecting rod can move in the limiting block, and then, the fixing rod is used for fixing. Therefore, the distance between the connecting plate and the mask body can be adjusted, the situation that an upper bandage is fixed to the eyebrow bone when the mask body is used is avoided, the mask also avoids that adoctor observes the eye situation of a patient, the problem that the distance between the connecting plate and the mask body cannot be adjusted when an existing mask is used is solved, and the practicability of the mask is improved; and the problem that when an existing breathing machine mask is used, connection between the lower binding band and the fixing block is not firm enough is solved, andthe stability of the mask in the using process is improved.

Description

technical field [0001] The invention relates to a ventilator mask, in particular to a severe ventilator mask, and belongs to the technical field of mask application. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. [0003] With the improvement of ventilator functions, the current ventilator masks are also developing rapidly. When the existing ventilator masks are in use, the main body of the mask needs to be bound to the patient's face through the upper and lower straps. The distance between the strap and the lower strap is fixed and cannot be adjusted according to the length of the patient's face. When the upp...

AI Technical Summary

Problems solved by technology

[0003] With the improvement of ventilator functions, the current ventilator masks are also developing rapidly. When the existing ventilator masks are used, they need to pass the upper and lower straps , to bind the main body of the mask to the patient's face. Since the distance between the existing upper strap and the lower strap is fixed, it cannot be adjusted according to the length of the patient's face. Some upper straps of the mask may be bound when in use. At the brow bone of the patient, it is easy to cause discomfort to the patient, affect the doctor's observation of the patient's eye condition, and reduce the practicability of the ventilator mask

[0004]The lower strap of the existing mask is generally directly connected to the main body of the mask through the hook body, and no auxiliary fixing structure is provided. When the doctor moves the patient's head, May cause the lower strap on one side to fall off, reducing the stability of the mask during use
