UTILITY MODEL CONTENTS

[0006] In view of the above problems, the utility model aims at providing an improved breathing machine mask, which can be adaptively adjusted according to the face condition of different patients, especially for some people with mandibular retrusion or small mandible and toothless old people, who also have rhinitis or airway hyperresponsiveness, can be fitted with their faces, will not cause the leakage of inhaled drugs and oxygen, resulting in waste of drugs and oxygen, and also can make the treatment and oxygen absorption effect of patients better.

[0007] The main idea of ​​the technical solution adopted by the present invention is as follows: for some people with a retracted mandible or a relatively small mandible, as well as edentulous elderly people, and patients with rhinitis or airway hyperreactivity, the regular mask body has a poor fit with their faces and cannot completely cover their faces, which may cause problems such as air leakage. Therefore, in this application, the respiratory mask is set to a shape that is small at the top and large at the bottom, so that the length of the extension part can compensate for the retracted mandible, etc., thereby enabling the respiratory mask to better wrap the faces of such patients.

[0008] In order to achieve the above purpose, the technical solutions adopted by this utility model are as follows:

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] A respirator is a medical device, typically made of soft material, that covers the patient's mouth and nose to provide oxygen or other respiratory support. It is widely used in medical settings such as emergency rooms, operating rooms, and intensive care units (ICUs) to assist or maintain breathing. Medical respirators come in a variety of types and sizes, allowing for the selection of different models and sizes tailored to the patient's specific needs.

[0026] However, for some people with a retruded or small mandible, elderly people without teeth, and those with rhinitis or airway hyperresponsiveness, using current home ventilator oronasal masks is less comfortable and can leak. This can lead to leakage of inhaled medication and oxygen, resulting in waste of medication and oxygen, and also affect the patient's treatment and oxygen inhalation, reducing treatment effectiveness.

[0027] Therefore, this application discloses an improved ventilator mask. For the specific structural diagram, please refer to Figs. 1-3 The improved ventilator mask includes a mask body 1, which is provided with an adjustment structure that can be adjusted according to different patient facial conditions. The mask body 1 of the present application is also provided with exhaust holes 2. The exhaust holes 2 are small holes evenly distributed on the mask, which are responsible for exhausting the patient's exhaled air. The design of the exhaust holes 2 can effectively prevent the accumulation of carbon dioxide and ensure smooth breathing.

[0028] The mask body 1 used in the present application is made of silica gel or polyvinyl chloride, etc. It should be noted that the mask body 1 is also provided with a headband, a tracheal catheter and a valve. The headband is usually made of elastic material and is used to fix the mask on the head of the patient to ensure that the gas inlet is in the nose. The tracheal catheter 3 is a pipeline connecting the mask and the oxygen or other gas source and is usually made of soft plastic or rubber and has certain bending and flexibility to facilitate the patient's breathing. The valve is usually located on the tracheal catheter and is used to control the flow and pressure of the gas to ensure that the patient obtains the correct oxygen concentration and flow.

[0029] The headband, the tracheal catheter 3 and the valve used in the present application are all existing products. The structure of the above components and the connection relationship with the mask body 1 are all prior art and will not be described in detail here.

[0030] An extension 4 for facilitating the fitting of the lower jaw of different patients is attached to the lower part of the mask body 1. The length of the extension 4 is 1.5 cm. The extension 4 with a curvature is added to the lower part of the mask body 1. It is more comfortable and fitting for patients with a retruded lower jaw, a small lower jaw and elderly patients without teeth, and it better avoids air leakage at the lower part. If there is air leakage, the pressure of the breathing machine will be too large, the patient will wake up and the effect will be poor. By measuring the length of the mask body 1 worn by some patients and observing the fitting effect after wearing, it is found that the increased length of 1.5 cm is more suitable for patients with a retruded lower jaw, a small lower jaw and elderly patients without teeth. The conventional mask body 1 basically has the same length at the upper and lower parts and has a regular shape. For some people with a retruded lower jaw or a small lower jaw and elderly patients without teeth, and at the same time for patients with rhinitis or airway hyperresponsiveness, the regular mask has poor fitting degree with their faces and cannot completely wrap their faces, which may cause air leakage and other problems. Therefore, the breathing mask is designed to be large at the lower part and small at the upper part in the present application, so that the length of the extension can compensate for the retrusion of the lower jaw and the like, thereby making the breathing mask better wrap the faces of such patients.

[0031] On the basis of the extension 4 for facilitating the fitting of the lower jaw of different patients being provided at the lower part of the mask body 1, since different patients need to adjust the length of the mask, the present application further provides an adjusting structure on the mask body 1 provided with the extension 4. The adjusting structure comprises an elastic adjusting part attached to the side of the mask body 1 fitting the face and an air cushion layer 5 provided in the inside of the mask body.

[0032] Specifically, the elastic adjusting part is a multi-layer wrinkled soft rubber layer 6 which is adapted to the shape of the side of the mask body 1 fitting the face. As shown in Fig. 2 The material of the multi-layer wrinkled soft rubber layer 6 is silica gel and has soft texture. When it contacts the face of the patient, it can avoid causing damage to the face of the patient. Due to the soft texture of the silica gel, it can be easily adjusted according to the faces of different patients and is very convenient to use.

[0033] It should be noted that the number of layers of multi-layer pleats can be increased or decreased according to actual needs, and no further restrictions are imposed here. Fig. 2 Taking the three layers of folds in FIG. 1 as an example, the three layers of folds can be stretched or compressed according to the needs of the patient, so that the mask body 1 fits the patient's face better.

[0034] In order to provide support for the mandible of people with retracted or small mandibles, as well as elderly people without teeth, when the mandible is inside the mask, making the patient more comfortable, the present application also provides an air cushion layer 5 inside the mask body 1, which can change its volume by inflation and deflation. The air cushion layer 5 is a hollow silicone air bag. The outer wall of the air cushion layer 5 is bonded to the lower part of the mask body 1, and the side of the air cushion layer 5 is provided with air holes (not shown) for easy inflation and deflation. The air holes are normally closed by a piston. If the air cushion layer 5 needs to be inflated or deflated, an air pump is used to inflate the air cushion layer 5 through the air holes or the air cushion layer 5 is deflated by pressing it.

[0035] Example

[0036] Before wearing the respirator mask of the present application, you should first wash your face and remove excess facial oil. When wearing it, you need to hold the mask with your hands to fit it to your face, buckle the nasal cavity, and adjust the extension part 4 under the mask body to fit the patient's lower jaw. Then adjust the multi-layer wrinkled soft rubber layer 6 and the air cushion layer 5 to make it fit the patient's face, then fix the respirator mask, stick the fixing strap of the respirator mask so that the entire hood no longer moves. After wearing, you need to lie down to check the wearing effect, adjust a comfortable sleeping position, and then ask a doctor to check whether there is any air leakage. If there is no air leakage, it is generally considered that the respirator mask is effective.
