Description
Technical Field
[0001] This utility model belongs to the field of face mask technology, specifically a breathable face mask that prevents pressure marks. Background Technology
[0002] A ventilator is a medical device that delivers oxygenated air into the lungs and expels carbon dioxide from the body, assisting the respiratory system in ventilation. It primarily applies pressure directly to the airway opening; during inhalation, the pressurized air is forced into the alveoli, and during exhalation, the air is passively expelled through the chest and lungs. Patients using a ventilator need to have it covered their face.
[0003] Existing breathable face masks are usually made of relatively hard materials, which can easily leave pressure marks on the face after prolonged wear, and may even lead to problems such as facial pressure ulcers and toothache. Summary of the Invention
[0004] The purpose of this invention is to provide a breathable face mask that prevents pressure marks, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A breathable, pressure-resistant face mask is provided, comprising a face mask body. A locking block is fixedly connected to the side surface of the face mask body, and a connecting frame is engaged at the end of the locking block. A T-shaped groove is formed inside the connecting frame, and a compression spring is fixedly connected to the inner wall of the T-shaped groove. A T-shaped slider is slidably connected to the inner wall of the T-shaped groove, and the side surface of the T-shaped slider is in contact with the end of the compression spring. A connecting seat is fixedly connected to the end of the T-shaped slider away from the compression spring, and a rubber ring is fixedly connected to the side surface of the connecting seat. The rubber ring is in contact with the patient's face. A first telescopic strap and a second telescopic strap are provided on the outside of the face mask body. In use, the face mask body is placed on the patient's face using the first and second telescopic straps, so that the rubber ring is in contact with the patient's face. When the patient's face is under pressure, the connecting seat drives the T-shaped slider to compress the compression spring, creating a relative displacement space between the connecting seat and the connecting frame. This provides a pressure-relieving zone for the connecting seat and the rubber ring, which helps to reduce the pressure of the face mask body on the patient's face.
[0006] Optionally, an air inlet pipe is fixedly connected to the outside of the mask body, and an air outlet is opened inside the mask body, with the air outlet located below the air inlet pipe.
[0007] Optionally, the connecting frame has an external mounting groove, the inner sidewall of the mounting groove has a slot, and the end of the slot has a protrusion that engages with the inside of the slot.
[0008] Optionally, the connecting frame is externally fixedly connected with a first connecting ring and a second connecting ring, and each of the first connecting ring and the second connecting ring is provided in two sets.
[0009] Optionally, a first sleeve ring is fitted around the two first connecting rings, and a second sleeve ring is fitted around the two second connecting rings. The first sleeve ring is fixedly connected to the end of the first telescopic belt, and the second sleeve ring is fixedly connected to the end of the second telescopic belt.
[0010] Optionally, the number of compression springs is two, and they are symmetrically distributed vertically around the first connecting ring.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is equipped with a connecting frame, a compression spring, a T-shaped slider, a connecting seat, and a rubber ring. In use, the mask body is placed on the patient's face using the first and second telescopic straps, so that the rubber ring fits snugly against the patient's face. When the patient's face is under pressure, the connecting seat drives the T-shaped slider to compress the compression spring, creating a relative displacement space between the connecting seat and the connecting frame. This provides a pressure relief zone for the connecting seat and the rubber ring, which helps to reduce the pressure of the mask body on the patient's face.
[0012] 2. This utility model is provided with an installation groove, a locking block, and a locking slot. In use, the locking block on the side surface of the mask body corresponds to the installation groove on the outside of the connecting frame, and then the locking block engages with the inside of the locking slot, thereby realizing the rapid assembly of the mask body and the connecting frame and improving the assembly efficiency.

Detailed Implementation
[0016] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] Reference Figure 1-5 A pressure-resistant and breathable face mask includes a face mask body 1. A locking block 4 is fixedly connected to the side surface of the face mask body 1. A connecting frame 5 is locked to the end of the locking block 4. A T-shaped groove 8 is opened inside the connecting frame 5. A compression spring 9 is fixedly connected to the inner side wall of the T-shaped groove 8. A T-shaped slider 10 is slidably connected to the inner side wall of the T-shaped groove 8. The side surface of the T-shaped slider 10 is in contact with the end of the compression spring 9. A connecting seat 11 is fixedly connected to the end of the T-shaped slider 10 away from the compression spring 9. A rubber ring 12 is fixedly connected to the side surface of the connecting seat 11. The rubber ring 12 is in contact with the patient's face. A first elastic band 15 and a second elastic band 18 are provided on the outside of the face mask body 1. In use, the first telescopic strap 15 and the second telescopic strap 18 are used to put the mask body 1 on the patient's face, so that the rubber ring 12 fits the patient's face. When the patient's face is under pressure, the connecting seat 11 drives the T-shaped slider 10 to compress the compression spring 9, so that there is a relative displacement space between the connecting seat 11 and the connecting frame 5, thereby providing a pressure relief range for the connecting seat 11 and the rubber ring 12, which helps to reduce the pressure of the mask body 1 on the patient's face.
[0018] An air inlet pipe 2 is fixedly connected to the outside of the mask body 1, and an air outlet 3 is opened inside the mask body 1, with the air outlet 3 located below the air inlet pipe 2. When in use, the mask body 1 draws in oxygen through the air inlet pipe 2 and discharges it through the air outlet 3.
[0019] The connecting frame 5 has an external mounting groove 6, and an inner sidewall of the mounting groove 6 has a slot 7. The end of the locking block 4 is provided with a protrusion, which engages with the inside of the slot 7. In use, the locking block 4 on the side surface of the mask body 1 is aligned with the mounting groove 6 on the outside of the connecting frame 5, and then the locking block 4 is engaged with the inside of the slot 7, thereby realizing the rapid assembly of the mask body 1 and the connecting frame 5 and improving assembly efficiency.
[0020] The connecting frame 5 has a first connecting ring 13 and a second connecting ring 16 for external fixed connection, and two sets of each of the first connecting ring 13 and the second connecting ring 16 are provided. By providing two sets of the first connecting ring 13 and the second connecting ring 16, it is convenient to install the first telescopic belt 15 and the second telescopic belt 18.
[0021] Two first connecting rings 13 are fitted with first sleeve rings 14, and two second connecting rings 16 are fitted with second sleeve rings 17. The first sleeve rings 14 are fixedly connected to the end of the first telescopic belt 15, and the second sleeve rings 17 are fixedly connected to the end of the second telescopic belt 18. The first telescopic belt 15 is connected to the first connecting rings 13 by the first sleeve rings 14, and the second telescopic belt 18 is connected to the second connecting rings 16 by the second sleeve rings 17, thereby enhancing the stability of the connection between the first telescopic belt 15 and the second telescopic belt 18.
[0022] There are two compression springs 9, which are symmetrically distributed vertically around the first connecting ring 13. When the T-shaped slider 10 compresses the compression springs 9, the two sets of compression springs 9 can better bear the force on the T-shaped slider 10 and help it withstand pressure.
[0023] Working principle: When in use, the first telescopic strap 15 and the second telescopic strap 18 are used to put the mask body 1 on the patient's face, so that the rubber ring 12 fits the patient's face. When the mask body 1 is in use, oxygen is drawn in through the air inlet 2 and discharged through the air outlet 3. When the patient's face is under pressure, the connecting seat 11 drives the T-shaped slider 10 to compress the compression spring 9, so that there is a relative displacement space between the connecting seat 11 and the connecting frame 5, thereby providing a pressure relief zone for the connecting seat 11 and the rubber ring 12, which helps to reduce the pressure of the mask body 1 on the patient's face.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
