Description

Technical Field

[0001] The present application relates to the field of medical device technology, and more specifically, to a novel breathing mask. Background Art

[0002] The health of the respiratory system is being taken seriously by more and more people. It has been clinically proven that ventilators are very effective in improving obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD), and respiratory masks are one of the key accessories of ventilators.

[0003] The breathing mask is an important component that connects the breathing circuit and the patient. It is generally composed of a mask body, a cushion, a headband, a buckle, an anti-suffocation valve, a forehead pad assembly, a vent and a low-pressure oxygen interface. However, existing breathing masks have the following defects:

[0004] During the inhalation process, fresh gas is input → the ventilator outputs gas of the required pressure → breathing tube → breathing mask → user. Leakage or changes in the leakage rate of this gas circuit system may also affect the function and performance of the ventilator. The most likely place for seal leakage is the place where the cushion of the breathing mask meets the face. If the pressure of the cushion and the face is too high or too low, it is easy to leak.

[0005] During the exhalation process, exhaled carbon dioxide and other gases cannot be discharged from the mask in time, resulting in repeated inhalation of exhaled gases.

[0006] When the ventilator is paused or stops due to a malfunction, it cannot guarantee that the user can breathe normally. If the user needs more oxygen to ensure the treatment effect, a supplementary oxygen supply interface is required.

[0007] Therefore, effective design is needed to meet the above requirements to ensure sealing and comfort, so as to obtain the ideal treatment effect.

[0008] In view of this, we propose a new type of breathing mask. Utility Model Content

[0009] 1. Technical problems to be solved

[0010] The purpose of the present application is to provide a new type of breathing mask, which solves the technical problems raised in the above-mentioned background technology, achieves good sealing and comfort, and thus obtains an ideal therapeutic effect.

[0011] 2. Technical solution

[0012] The embodiment of the present application provides a novel breathing mask, including a mask body assembly, an anti-suffocation valve assembly and a forehead pad assembly.

[0013] As an optional solution of the utility model, the mask main body assembly includes a main body, a cushion, a buckle, a low-pressure oxygen interface rubber plug and a headband;

[0014] The cushion is detachably fixed on the main body;

[0015] Buckles are detachably fixed on both sides of the main body;

[0016] A plurality of vent holes are fixedly arranged on the main body;

[0017] A low-pressure oxygen interface is fixedly provided on the main body;

[0018] The low-pressure oxygen interface rubber plug is detachably fixed on the low-pressure oxygen interface;

[0019] The headband is detachably fixed on the buckle.

[0020] A forehead pad assembly is detachably fixedly arranged on the upper end of the mask body.

[0021] Through the above technical solution, the cushion and facial contour dimensions are first collected for different face shapes, and then the facial contour curve is designed after data analysis to make the cushion fit more closely to the face. The buckle is designed with a guide groove to facilitate quick insertion. At the same time, the buckle has a certain elasticity and has a "click" feedback after being inserted into place. The optimized detachable buckle is convenient for the user to fix the breathing mask on the face with a headband. The vent is set near the nostrils to facilitate the timely discharge of exhaled carbon dioxide and other gases from the mask, thereby avoiding repeated inhalation of exhaled gases. A low-pressure oxygen interface is set on each side of the breathing mask, so that it is convenient to connect no matter which side the gas source is on; when using supplementary oxygen supply, in order to prevent the plug from being lost, a card strip is designed on the plug and stuck on the main body; when supplementary oxygen supply is not required, the low-pressure oxygen interface plug is used to cover the low-pressure oxygen interface.

[0022] As an optional solution of the utility model, the forehead pad assembly includes a forehead silicone pad, a forehead silicone pad support frame, a telescopic rod and a knob;

[0023] The forehead silicone pad and the forehead silicone pad support frame are detachably fixed together;

[0024] The forehead silicone pad support frame is rotatably arranged on the telescopic rod;

[0025] The telescopic rod is slidably arranged in the circular hole at the upper end of the main body;

[0026] A nut is fixedly arranged on the telescopic rod;

[0027] The knob is rotatably arranged in the circular hole at the upper end of the main body;

[0028] A screw rod is fixedly arranged on the knob, and the screw rod is matched with the nut thread for connection.

[0029] A triangular frame is provided on the forehead silicone pad.

[0030] Through the above technical solution, the triangle has the characteristics of stability, and the silicone has good elasticity. This structure takes into account deformation and support, can match and fit various forehead shapes, maximize the contact area, and can achieve good cooperation between the silicone pad and the forehead. Under the condition of a certain tension of the headband, the larger the contact area, the smaller the pressure, and the more comfortable the user feels when wearing the breathing mask of this structure. The two buckles on the telescopic rod are stuck in the arc groove of the forehead silicone pad support frame and can be rotated to a certain angle. When the telescopic rod is adjusted to move, the good cooperation between the forehead silicone pad and the forehead can also be ensured. The telescopic rod slides along the limit in the circular hole at the upper end of the main body, and a nut is designed inside the telescopic rod. The knob can rotate around the limit in the circular hole at the upper end of the main body, and a screw rod is designed on the knob. When the knob is turned, the screw rod rotates synchronously at the same time. Because it is limited, the nut matching the screw rod moves, so that the telescopic rod slides along the limit in the circular hole at the upper end of the main body. The forehead and face can be considered static. When the telescopic rod moves back and forth, the pressure between the silicone cushion and the face can be evenly adjusted. The tightness should be based on achieving a seal. This design achieves good sealing.

[0031] An anti-suffocation valve assembly is detachably fixedly arranged at the lower end of the mask body.

[0032] As an optional solution of the utility model, the anti-suffocation valve assembly includes an elbow, an anti-suffocation valve and a pipe joint;

[0033] The elbow is rotatably arranged in the circular hole at the lower end of the main body;

[0034] The anti-suffocation valve is detachably arranged in the groove on the elbow;

[0035] The pipe joint is rotatably arranged on the elbow;

[0036] A gas exchange hole is provided on the elbow.

[0037] Through the above technical solution, when the ventilator works normally, it will output fresh air with a pressure of not less than 4cmH2O. At this time, the anti-suffocation valve flips upward under the action of the positive pressure in the pipeline, closing the gas exchange hole on the elbow. When the ventilator is paused or stops due to a malfunction, the positive pressure in the breathing circuit is less than 4cmH2O. At this time, the anti-suffocation valve flips downward, and the gas exchange hole on the elbow opens, that is, another air path opens, thereby ensuring that the user can breathe fresh air normally. The rotatable elbow and pipeline connector can reduce or avoid the displacement of the breathing mask when the user changes his sleeping position such as turning his head or turning over, thereby maximizing the treatment effect of the user.

[0038] As an optional solution of the present invention, the pitch of the screw rod and the nut is 4.5 mm.

[0039] As an optional solution of the present invention, the diameter of the vent holes is 0.8 mm, and the number of the vent holes is twenty-five.

[0040] As an optional solution of the utility model, silica gel is fixedly provided on the front side of the anti-suffocation valve, and the thickness of the silica gel is 0.8 mm.
