Description

Breathing machine face guard with good leakproofness

Technical Field

The utility model belongs to the technical field of respirator face guard, especially, relate to a respirator face guard with good leakproofness.

Background

A noninvasive ventilator is a method of providing effective mechanical ventilation by a ventilator in connection with a nasal or oronasal mask. The method has the characteristics of small pain, flexible application, intermittence, sustainable application and the like, and can effectively reduce the incidence rate of ventilator-associated pneumonia VAP. The noninvasive ventilator has obvious effects of shortening invasive ventilation time, reducing complications, improving survival rate, reducing medical expenses and the like. The noninvasive ventilator face mask is a connector which is specially used for noninvasive ventilators and is worn on the face of a patient, and the connection method of the noninvasive ventilator face mask is a nose mask, an oral-nasal face mask, a full face mask, a nasal sac tube, a mouth piece and the like.

Clinically, noninvasive positive pressure mechanical ventilation is increasingly applied to treating patients with acute and chronic respiratory failure, heart failure and the like, and can prevent partial patients from tracheal intubation. When in noninvasive ventilation, the respirator is connected with the face of a patient through the mask, and for the patient with a gastric tube, gas is easy to leak from a gap at the joint of the mask after the patient is provided with the mask, so that gas leakage is caused.

The patent numbers are: CN201220554260X, publication (bulletin) No. is: CN202920766U, name of utility model: an operable noninvasive ventilator mask is disclosed, which comprises a mask body, wherein two operation hole channels are symmetrically arranged on the mask body along the central line of the mask body, the operation hole channels obliquely upwards pass through the mask body from the outer side of the mask body and are aligned with nostrils of a patient, and a cover body for sealing the operation hole channels is arranged at the outer openings of the operation hole channels. Although this patent has solved can insert the stomach tube (keep somewhere the stomach tube) and (or) go on the problem of bronchoscopy through the handle hole, after the operation is accomplished, when need keeping somewhere the stomach tube, because this handle hole with keep somewhere between the stomach tube gapped, can lead to gas leakage, when the clearance is big, the breathing machine can't produce gas pressure in the face guard, causes not to have the respiratory treatment failure of wound.

The application numbers are: CN201420529836.6, publication (bulletin) No. CN204133999U, name of utility model: the noninvasive ventilator mask comprises a mask shell, wherein the upper surface of the mask shell is provided with a ventilator air pipe joint, a nasogastric tube insertion port and a liquid diet insertion port, and the side surface of the mask shell is provided with an elastic fixing belt … … for fixing the mask shell to the head of a patient. The mask is provided with a nasogastric tube insertion port and a liquid diet insertion port, but the problem of air leakage at the ports during intubation or when a nasogastric tube is left in place is still not solved.

Therefore, how to solve the above problems becomes a focus of research by those skilled in the art.
