Abstract
Description
Technical Field

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0031] Respiratory masks are widely used in medical places such as emergency treatment, operating rooms, and intensive care units to help patients breathe or maintain respiratory function. Currently, existing respiratory masks need to be worn in front of the user's face and then oxygen is supplied through an oxygen tube. However, long-term use of the mask will produce water vapor inside the mask, which will accumulate inside the mask and cause the inside of the mask to become humid, which will not only affect the oxygen transfer efficiency, but may also increase the user's breathing resistance and make him feel uncomfortable.
[0032] Based on this, the present application provides a water vapor-proof breathing mask, which can reduce the water vapor inside the breathing mask body, avoid affecting the oxygen transfer efficiency, and improve the patient's comfort in oxygen inhalation.
[0033] See also Figures 1 to 5, the present application provides a water vapor-proof breathing mask, comprising: a breathing mask body 1, an air inlet one-way valve 10, an air outlet one-way valve 9, an air inlet component 5, a condenser 6, a liquid collecting box 8, and a timed exhaust component; the breathing mask body 1 is provided with an air inlet channel 4 and an air outlet channel 7, the air outlet channel 7 is arranged below the air inlet channel 4, the air inlet one-way valve 10 and the air inlet component 5 are arranged inside the air inlet channel 4, the air outlet one-way valve 9 and the timed exhaust component are arranged inside the air outlet channel 7, the condenser 6 is arranged outside the air outlet channel 7, and the liquid collecting box 8 is installed on the air outlet channel 7, the air inlet channel 4 is used to supply oxygen into the breathing mask body 1, the air outlet channel 7 cooperates with the timed exhaust component to extract the gas inside the breathing mask body 1 outward, and is used to condense the gas in the air outlet channel 7 into liquid through the condenser 6 and collect it in the liquid collecting box 8.
[0034] In the embodiment of the present application, a soft pad 11 is provided on the outer surface of the respiratory mask body 1, so that when the patient wears the respiratory mask body 1, the soft pad 11 will directly contact the patient's facial skin, thereby reducing the impact of the respiratory mask body 1 on the patient's skin and improving the comfort of the patient's wearing. Among them, a plurality of fasteners 3 are also provided on the outside of the respiratory mask body 1, and the connection between the plurality of fasteners 3 and the respiratory mask body 1 is an integral molding setting, that is, the connection between the fasteners 3 and the respiratory mask body 1 is a non-detachable installation, and a strap 2 is buckled on the fastener 3, and the respiratory mask body 1 can be fixed to the patient's face through the plurality of straps 2, so as to supply oxygen to the patient.
[0035] Among them, dual ventilation channels are arranged on the breathing mask body 1, one is the air inlet channel 4, and the other is the air outlet channel 7. The air inlet channel 4 is arranged above the air outlet channel 7, so that the gas exhaled by the patient can flow out from the air outlet channel 7 better. Specifically, an air inlet opening is arranged on the breathing mask body 1, and the connection mode of the air inlet channel 4 and the air inlet opening is an integrated installation. An air inlet check valve 10 is arranged in the air inlet channel 4, and the air inlet check valve 10 only allows oxygen to enter the breathing mask body 1 through the air inlet channel 4, while the gas inside the breathing mask body 1 cannot enter the air inlet channel 4, so as to ensure the purity of the oxygen inside the air inlet channel 4 and avoid being affected by the gas inside the breathing mask body 1.
[0036] Similarly, the breathing mask body 1 is provided with an air outlet opening, and the connection mode of the air outlet channel 7 is also integrated installation. An air outlet check valve 9 is provided in the air outlet channel 7. The air outlet check valve 9 only allows the gas inside the breathing mask body 1 to flow into the air outlet channel 7, and the gas in the air outlet channel 7 cannot flow back into the breathing mask body 1, thereby avoiding pollution of the gas inside the breathing mask body 1. And through the integrated installation mode, gas leakage can be effectively avoided at the connection between the air inlet channel 4 and the air outlet channel 7 and the breathing mask body 1, ensuring the stable flow of gas.
[0037] It should be noted that the opening area of the air outlet opening is smaller than the opening area of the air inlet opening, so that after the external oxygen enters the inside of the breathing mask body 1, it can be fully absorbed by the patient, ensuring the patient's oxygen intake. The opening area of the air outlet opening is small, so that when the patient breathes oxygen, the loss of oxygen can be effectively reduced. When the patient exhales, the timed exhaust component will automatically open according to the set time, increase the circulation speed of the gas, and thus the gas inside the breathing mask body 1 will be drawn out through the air outlet channel 7. The condenser 6 can be used to cool the drawn gas into liquid and then collect it. Since the gas inside the breathing mask body 1 is drawn out, the water vapor inside the breathing mask body 1 can be reduced, avoiding the impact on the oxygen transfer efficiency and improving the comfort of the patient's oxygen inhalation.
[0038] The air intake assembly 5 includes an air intake filter plate and a drying plate, both of which are arranged in the air intake channel 4, the air intake filter plate is arranged on one side of the drying plate, the air intake check valve 10 is arranged on one side of the drying plate, the air intake check valve 10 is close to the breathing mask body 1, and the air intake filter plate is arranged to filter the oxygen in the air intake channel 4 to ensure the purity of the oxygen, and the drying plate is arranged to reduce the humidity of the oxygen and maintain a certain degree of dryness, so that when the oxygen flows into the inside of the breathing mask body 1, it can be better absorbed by the patient.
[0039] Among them, the timed exhaust assembly includes a timer and a micro exhaust fan 12, the timer is connected to the micro exhaust fan 12, the timer is used to control the opening and closing of the micro exhaust fan 12, and the micro exhaust fan 12 is arranged between the air outlet check valve 9 and the condenser 6. The setting time of the timer can be set according to the patient's respiratory frequency. When the patient's respiratory rate is high, the setting time of the timer can be shortened, and when the patient's respiratory rate is low, the setting time of the timer can be lengthened. It is necessary to ensure that when the patient exhales, the timer controls the micro exhaust fan 12 to turn on, and the gas inside the breathing mask body 1 is pumped into the air outlet pipe, and the condenser 6 is configured to condense the gas into liquid, and transport it to the liquid collection box 8 through the water outlet pipe of the condenser 6. In order to facilitate disassembly and subsequent use, the liquid collection box 8 can be detachably installed on the air outlet channel 7.
[0040] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
