[0002] The respiratory isolation and disinfection device in the pediatric infectious disease ward mainly refers to equipment used to prevent pathogens from spreading to other patients or medical staff through the respiratory tract. This usually includes respiratory masks and ventilators. These devices can provide air filtration and isolation. The ventilator delivers air into the patient's lungs through a pipe and exhausts the waste gas out of the body, while the respiratory mask delivers filtered air into the patient's nasal cavity or oral cavity.

[0003] However, when the breathing mask is used in conjunction with a ventilator, the breathing mask is pressed against the patient's facial skin and will be worn for a long time. The existing breathing mask is not convenient for changing the compression position. The facial skin of children is relatively delicate. Long-term compression may cause compression injuries. In addition, the existing breathing mask is not convenient for simply and gently massaging the compressed facial skin area, and it is not convenient to promote blood circulation through massage.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention provides a pressurizing and fixing unit. When the patient wears the breathing mask in conjunction with the ventilator, the breathing mask can be fixed by inflating and deflating the first annular airbag and the second annular airbag, and the contact between the airbag and the patient's facial skin is softer and more comfortable. The skin of child patients is more delicate and can effectively prevent the occurrence of compressive injuries. At the same time, after one of the airbags is fixed for a long time, the medical staff can replace it with another airbag to inflate and fix it, and the position of the airbag compression can be changed, which further reduces the occurrence of compressive injuries. When the two annular airbags are inflated at the same time, pressure can be applied to the inside of the two annular airbags to make them shrink and expand back and forth. The back and forth flexible squeezing of the annular airbags can appropriately and gently massage the compressed part of the patient's face. Local massage of the compressed part can effectively promote blood circulation and further reduce the occurrence of compressive injuries.

[0021] 2. The present invention provides an auxiliary unit. When a patient wears a breathing mask in conjunction with a ventilator, when medical staff need to take off the mask to observe and care for the patient's face, the medical staff does not need to take off the breathing mask as a whole. The medical staff only needs to open the transparent mask to observe and care for the patient's face, which reduces the operation steps of the medical staff and the frequency of the patient taking off the breathing mask. It can better assist the medical staff in operating, which is more convenient and quick.

[0022] 3. The present invention sets a disinfection mechanism. When the patient wears a breathing mask in conjunction with a ventilator, bacteria may exist in the air. Children have relatively weak resistance. By setting up air disinfection, the external air delivered by the ventilator can be disinfected to a certain extent, and the gas exhaled by the patient can be further disinfected to a certain extent, thereby further ensuring the cleanliness of the air breathed by the patient, playing a respiratory isolation disinfection role, effectively reducing or even eliminating the possibility of infection, and providing further protection for the patient while protecting medical staff.

By providing a gear 2122 and a toothed plate 2120, when the gear 2122 is meshed with the toothed plate 2120 and the gear 2122 rotates, the toothed plate 2120 can be driven to move, and the movement of the toothed plate 2120 can drive the piston rod 2119 to move at the same time. By providing a micro motor 2121, the gear 2122 can be driven to rotate. By providing a connecting pipe 2123 and a cavity box 2124, the air in the first annular airbag 2106 and the second annular airbag 2110 can enter the cavity box 2124 to complete the circulation.

[0041] The surfaces of the two chamber boxes 2124 are fixedly connected with exhaust pipes 2125, the inner walls of the two exhaust pipes 2125 are fixedly connected with sealing rubber pads 2126, the surfaces of the two chamber boxes 2124 are fixedly connected with first springs 2127, the exhaust pipes 2125 are sleeved on the surfaces of the first springs 2127, one end of the two first springs 2127 are fixedly connected with sealing balls 2128, the sealing balls 2128 and the sealing rubber pads 2126 are used in conjunction with each other and are in close contact with each other, and the surfaces of the two exhaust pipes 2125 are fixedly connected with first springs 2127. The surfaces of the two pressing blocks 2131 are fixedly connected with two square sleeve blocks 2129, the inner walls of each of the two square sleeve blocks 2129 are slidably connected with a sliding block 2130, and the opposite sides of each of the two sliding blocks 2130 are fixedly connected with a pressing block 2131. The surfaces of the two pressing blocks 2131 are fixedly connected with a second spring 2132, and the other end of the second spring 2132 is fixedly connected to the surface of the exhaust pipe 2125. The inner walls of the two pressing blocks 2131 are fixedly connected with a push rod 2133, and the push rod 2133 cooperates with the sealing ball 2128. In use, the surfaces of the two pressing blocks 2131 are fixedly connected with a gear rod 2134, and the number of the gear rods 2134 is several.

By setting the square sleeve block 2129, the movement of the sliding block 2130 can be smoother and play a guiding role. The user can press the pressing block 21 31, push the sliding block 2130 to slide on the inner wall of the square sleeve block 2129, and at the same time, the pressing block 2131 can drive the push rod 2133 to move forward. The forward movement of the push rod 2133 can push the sealing ball 2128 to separate from the surface of the sealing rubber pad 2126, so as to play the role of exhaust and release the gas in the first annular airbag 2106 and the second annular airbag 2110. By setting the gear lever 2134, an exhaust space can be formed between the pressing block 2131 and the exhaust pipe 2125.

[0042] The specific implementation method of this embodiment is as follows: the medical staff places the mask body 1 and the transparent mask 2101 on the patient's face and adjusts the position, puts the elastic band 2103 on the patient's head, and fixes the elastic band 2103 with Velcro 2104. After wearing it, the medical staff starts the micro air pump 2116 on one side of the box body 2107 through the external control switch. The micro air pump 2116 is powered by an external power supply. The air generated by the operation of the micro air pump 2116 is transported to the cavity 2114 through the connecting pipe 2117, and then the gas is transported to the first annular airbag 2106 through the first air pipe 2111 through the one-way valve 2113. When it is worn for the first time, the first annular airbag 2106 is in contact with the patient's face. When the first annular airbag 2106 is worn, the air is transported to the first annular airbag 2106 through the first air pipe 2111. When the bag 2106 is inflated, its surface will contact with the patient's facial skin. At the same time, because the expansion of the first annular airbag 2106 leads to a reduction in space, the elastic band 2103 can be tightened to a certain extent. At this time, the mask body 1 and the transparent mask 2101 can completely and comprehensively cover the patient's face. When worn for a long time, the user starts the micro air pump 2116 on the other side of the box body 2107 through an external control switch to inflate the second annular airbag 2110. When the second annular airbag 2110 is inflated and contacts with the patient's facial skin, the medical staff can press the pressure block 2131, and the pressure block 2131 drives the ejector rod 2133 to move forward to push the sealing ball 2128 in the exhaust pipe 2125 out of the sealing rubber pad 212 6. At this time, the air in the first annular airbag 2106 will be discharged through the connecting tube 2123 and the cavity box 2124, completing the exhaust of the first annular airbag 2106 to make it shrink. When the first annular airbag 2106 is exhausted and completely shrinks to its original state, the operation is completed, and the purpose of changing the skin compression position can be achieved. At the same time, the user can inflate the first annular airbag 2106 and the second annular airbag 2110 to the same expansion degree through the micro air pump 2116, and at this time, the first annular airbag 2106 and the second annular airbag 2110 are both in contact with the patient's face. At this time, the first annular airbag 2106 and the second annular airbag 2110 can continue to expand. At this time, the user starts the micro motor 2121 through the external control switch, and the micro motor The motor 2121 is powered by an external power supply, and the output end of the micro motor 2121 drives the gear 2122 to rotate. The rotation of the gear 2122 can drive the toothed plate 2120 meshing therewith to move. The movement of the toothed plate 2120 can drive the piston rod 2119 to slide on the inner wall of the piston tube 2118. Because there is air in the piston tube 2118 during inflation, when the piston rod 2119 pushes the piston head, part of the air in the piston tube 2118 can be pushed into the first annular airbag 2106 and the second annular airbag 2110. At this time, due to the elastic properties of the first annular airbag 2106 and the second annular airbag 2110, they will expand to a certain extent under pressure. When the piston rod 2119 drives the piston head to pull back,The air in the first annular airbag 2106 and the second annular airbag 2110 can be partially extracted to allow the first annular airbag 2106 and the second annular airbag 2110 to contract to a certain extent. The first annular airbag 2106 and the second annular airbag 2110 can gently press the compressed facial skin of the patient through this back and forth expansion and contraction. This gentle massage can promote local blood circulation in the compressed area to a certain extent. The micro motor 2121 is set to reciprocate forward and reverse rotation, which can achieve the reciprocating push and pull of the piston rod 2119.

At this time, the medical staff only needs to pinch the support plate 2204 to open the transparent mask 2101 as a whole. The setting of the damping shaft 2202 can make the transparent mask 2101 have a certain damping effect when it is flipped and opened, and can maintain the positioning of various opening and flipping angles. When the medical staff wants to close the transparent mask 2101, they only need to pinch the support plate 2204 to send the insert block 2205 into the fixed shell 2208. At this time, the positioning pin 2207 will shrink due to the pressure of the fixed shell 2208. When it reaches the through hole set in the fixed shell 2208, the positioning pin 2207 cancels the pressure and the reaction force of the third spring 2206 can push it into the through hole set in the fixed shell 2208, and the transparent mask 2101 can be fixed at this time.
