Nose-compression-free noninvasive ventilation mask

Abstract

The invention relates to the technical field of medical instruments, and discloses a nose-compression-free noninvasive ventilation mask. The mask comprises a mask body; a compression-free protection mechanism is arranged at the nose position of the mask body; a ventilation connecting pipe is fixedly connected to the center of the top of the mask body; the ventilation connecting pipe is connected with an oxygen catheter through a disassembly and assembly mechanism; the side surface of the mask body fixedly communicates with an air outlet pipe; the compression-free protection mechanism comprisesa skin-friendly layer, a pressure reduction layer and a protection layer; the pressure reduction layer is located between the skin-friendly layer and the protection layer; the skin-friendly layer islocated on the outer side of the mask body; the upper surface of the skin-friendly layer is fixedly connected with the lower surface of the pressure reduction layer; the upper surface of the pressurereduction layer is fixedly connected with the lower surface of the protection layer; and the upper surface of the protection layer is fixedly connected with the nose position of the mask body. According to the nose-compression-free noninvasive ventilation mask, the nose of a patient is free of compression, pressure sores caused to the nose are avoided, and the oxygen catheter can be conveniently and rapidly disassembled and assembled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mask for nasal pressure-free non-invasive ventilation. Background technique [0002] With the help of a ventilator, mechanical ventilation is used to maintain airway patency, improve ventilation and oxygenation, prevent the body from hypoxia and carbon dioxide accumulation, in order to make the body possible to survive the respiratory failure caused by the basic disease, and to treat the basic disease. creating condition. Mechanical ventilation is a ventilation method that uses mechanical devices to replace, control or change spontaneous breathing movements. [0003] Patients with non-invasive ventilation often need to have a certain pressure to press the nose and face because they need to ensure the airtightness between the mask and the face. However, due to the lack of subcutaneous fat in the nose, pressure sores will still inevitably occur even with inflatable masks...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mask for non-invasive ventilation without nasal pressure, which has the advantages of no pressure on the nose and convenient disassembly and assembly of oxygen tubes, and solves the problem that the mask for non-invasive ventilation in the prior art is easy for patients. Pressure sores on the nose, and cumbersome disassembly and assembly between the mask and the oxygen catheter
