Background

Assisted respiration is an important medical technical means, is an important means for respiratory therapy and respiratory support, and is suitable for patients with pulmonary ventilation and pulmonary ventilation dysfunction caused by various reasons and respiratory failure caused by various reasons. Therefore, assisted breathing is widely used in clinical departments at various levels of hospitals of different sizes. Correspondingly, the breathing mask and the oxygen mask required by auxiliary breathing are widely used, and the use rate can reach more than 90% particularly in clinical departments such as the department of critical medicine and the department of respiration. However, through observation of the use of clinical ventilation masks, it has been found that there are some disadvantages.

Various types of existing ventilation mask materials are various, for example, a medical oxygen inhalation mask is made of polypropylene and polyvinyl chloride materials, the edge contacting with the skin of the face is in a strip shape, and a strap is used for fixing; the anaesthetic mask is made of soft 6866 medical polymer material, and the edge contacting with the facial skin is cylindrical; the noninvasive ventilator ventilation mask is made of silica gel materials, and the edge contacting with the facial skin is similar to the round edge of an anesthetic mask and the like.

The mask fixed by the lace is used for more than 3 hours, the obvious mask edge and the lace indentation can appear on the face of a patient, the skin of the face of the patient can be damaged due to long-time non-adjustment, and medical equipment damage is formed, so that the pain of the patient and the risk of medical disputes are increased.

Although the noninvasive ventilator mask used by critical patients is soft silica gel, when the mask is worn for too long time and the patients are irritated and not matched, the airtightness is affected, so that the air leakage is increased, and the treatment effect of the patients is reduced; meanwhile, the nurse needs to adjust the position of the mask in time, and the workload of the nurse is increased.

In chinese patent CN212327139U, a noninvasive mechanical ventilation mask is disclosed, and specifically discloses "a noninvasive mechanical ventilation mask cushion, comprising: the mask cushion body and the earmuffs arranged on two sides of the mask cushion body are provided with a lip nostril, the periphery of the lip nostril is provided with a groove matched with the edge profile of the bottom of the ventilation mask, the mask cushion body comprises a left cheek cushion, a nose cushion, a right cheek cushion and a chin cushion which are sequentially connected, the thickness of the nose cushion is respectively larger than that of the left cheek cushion, the right cheek cushion and the chin cushion, a plurality of air holes are formed in the left cheek cushion and the right cheek cushion, and a left gasket and a right gasket are further arranged below the left cheek cushion and the right cheek cushion. "

In the above-mentioned patent, the face guard pad area of coverage is too big, has still increased patient's facial skin burden when consuming the material, and uses the earmuff fixed face guard pad, has increased the burden of patient's ear.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the application include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

Example 1: as shown in fig. 1 to 3, a novel noninvasive ventilator mask pressure reduction device comprises a mask pad, wherein the mask pad comprises a pad a 1, the center of the pad a 1 is provided with a nostril 3, one surface of the periphery of the nostril 3, which is butted with a mask 7, is provided with a groove 4 consistent with the outline of the bottom edge of the mask 7, and the width of the groove 4 is 2 cm. The mask cushion also comprises a B-pad 2, the B-pad 2 coinciding with the bottom edge of the forehead fixing 8. The widest department at the horizontal both ends of A pad 1 is equipped with fixed band A5 and connects, the B pad 2 left and right sides is equipped with longitudinal connection's fixed band B9 respectively, fixed band A5 all adopts elastic fixation area with fixed band B9. The fixing strap A5 is connected with the A pad 1 in a sewing mode, and the fixing strap B9 is connected with the B pad 2 in a sewing mode. One side of A pad 1 and the facial contact of patient is equipped with opening 6, opening 6 is located the position of 5cm above the left junction of fixed band A5 and A pad 1 and the position of 5cm above the right junction of fixed band A5 and A pad 1 respectively, opening 6 is the incision form, and its degree of depth is half of A pad 1 thickness. The A cushion 1 and the B cushion 2 are both made of foam materials with good air permeability and strong skin-friendly property.

Wherein, A pad 1 and B pad 2 are used together, A pad 1 and B pad 2 are placed between face guard 7 and patient for the pressure of dispersion face guard 7 alleviates patient's skin burden. The groove 4 is attached to the bottom edge of the face mask 7 and is used for fixing the face mask 7 and improving the sealing performance of the face mask 7. The fixing strap A5 adopts an elastic fixing strap, so that the A cushion 1 and the face mask 7 can be fixed or detached conveniently.
