Description

Technical Field

[0001] This utility model relates to the field of oxygen mask technology that prevents side leakage, and in particular to an oxygen mask that prevents side leakage. Background Technology

[0002] Oxygen masks are important medical devices in clinical nursing. They are devices that transfer oxygen from a storage tank to the lungs. In addition to medical oxygen masks, there are also civilian aviation oxygen masks and other types, which play an important role in assisting in the treatment of diseases and protecting the safety of flight attendants.

[0003] A leak-proof oxygen mask, as disclosed in utility model patent application CN216855462U, includes a mask body and ventilation holes on the mask body. The lower end of the mask body has a soft rubber ring that conforms to the face, and the lower end of the rubber ring is bent inwards in an arc to form a fitting portion that increases the support area. It also includes a deformation mechanism located at the lower inner side of the rubber ring, capable of deforming the fitting portion under stress, and a resilient support mechanism located between the deformation mechanism and the mask body, capable of deforming and providing support under stress. The deformation mechanism can deform in all directions and upwards. The support mechanism deforms along with the deformation mechanism to provide support. The lower end of the mask is equipped with a rubber ring, providing deformation length and distance. The fitting part is bent inward to better fit the face and facilitate a proper fit after deformation. Pressing down on the first wire ring from the outside of the rubber ring allows for vertical and horizontal deformation to fit the face. However, this device has the same characteristics as most existing anti-leakage oxygen masks: the rubber ring on one side of the mask is prone to damage due to repeated deformation during prolonged use, as each person's facial features are different. This device does not allow for easy disassembly and replacement of the rubber ring, which can lead to some losses. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an anti-leakage oxygen mask, which can solve the technical problem that this device has the same characteristics as most existing anti-leakage oxygen masks, namely, the rubber ring on one side of the mask body is easily damaged due to repeated deformation during long-term use due to the different facial conditions of each person. However, this device cannot effectively disassemble and replace the rubber ring, which will cause certain losses.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a leak-proof oxygen mask, including an oxygen mask body, a sealing groove is provided on one side of the oxygen mask body, a sealing plate is inserted into the sealing groove, a rubber ring is provided on one side of the sealing plate, a pair of first fixing plates are provided on the sealing plate, a threaded rod is provided on one side of the first fixing plate, and a second fixing plate is provided on one side of the oxygen mask body, a through hole is provided on the second fixing plate, one end of the threaded rod passes through the through hole and extends to one side, and a nut is threadedly connected to the threaded rod.

[0006] As a preferred embodiment of this utility model, the rubber ring has an iron wire ring inside.

[0007] As a preferred technical solution of this utility model, the oxygen mask is provided with a limiting frame on both sides, and a rope is threaded through the two limiting frames.

[0008] As a preferred embodiment of this utility model, one end of each of the two ropes is fixedly connected to an elastic band.

[0009] As a preferred technical solution of this utility model, the oxygen mask body is provided with brackets on both sides, the brackets are threaded with bolts, and one end of the bolts is provided with a pressure plate.

[0010] As a preferred embodiment of this invention, one end of the oxygen mask is connected to the air duct.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the rubber ring is damaged, the nut can be rotated so that one end of the nut is no longer tightly fixed to the second fixing plate and can be removed from the threaded rod. Then, the rubber ring and the sealing plate can be pulled to one side until the sealing plate is removed from the sealing groove. This allows the rubber ring to be removed from the oxygen mask and replaced. During replacement, the sealing plate on one side of the rubber ring can be inserted into the sealing groove. At the same time, the threaded rod can be used to observe the through hole on the second fixing plate. Then, the nut can be screwed into the threaded rod until the nut is tightly fixed to the second fixing plate. This allows for the replacement and installation of the rubber ring. This device can effectively achieve the disassembly and replacement of the rubber ring. Attached Figure Description

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] Example

[0021] like Figures 1-5 As shown, the present invention provides an oxygen mask with a leak-proof design. The rubber ring 4 has an internal wire ring 10 with a certain deformation capacity, making it suitable for different users. The oxygen mask body 1 has a limiting frame 11 on both sides, and a rope 12 is threaded through each limiting frame 11. One end of each rope 12 is fixedly connected to an elastic band 13, which has good elasticity. The oxygen mask body 1 has a bracket 14 on both sides, and a bolt 15 is threaded onto the bracket 14. One end of the bolt 15 is provided with a pressure plate 16. One end of the oxygen mask body 1 is connected to the air duct 17.

[0022] In use, by rotating bolt 15, the rotation of bolt 15 can drive the pressure plate 16 to move until one side of the pressure plate 16 is no longer tightly fixed to the rope 12, thereby pulling the rope 12 to move along the limit frame 11 and adjusting the position of the rope 12 to meet the needs of different users. When the rope 12 moves to the appropriate position, rotate bolt 15 in the opposite direction, so that bolt 15 drives the pressure plate 16 to move to one side and tightly fix it to the rope 12. The pressure plate 16 has an anti-slip layer on one side, which can better fix the rope 12.

[0023] As a further implementation of this embodiment, such as Figures 1-6 As shown, a sealing groove 2 is provided on one side of the oxygen mask body 1, and a sealing plate 3 is inserted into the sealing groove 2. A rubber ring 4 is provided on one side of the sealing plate 3, and the rubber ring 4 is made of rubber. A pair of first fixing plates 5 are provided on the sealing plate 3. A threaded rod 6 is provided on one side of the first fixing plate 5, and a second fixing plate 7 is provided on one side of the oxygen mask body 1. A through hole 8 is provided on the second fixing plate 7. One end of the threaded rod 6 passes through the through hole 8 and extends to one side. A nut 9 is threadedly connected to the threaded rod 6. The rubber ring 4 fits tightly against the face of the human body, which can effectively prevent oxygen leakage.

[0024] When the rubber ring 4 is damaged during use, the nut 9 can be rotated so that one end of the nut 9 is no longer tightly fixed to the second fixing plate 7 and can be removed from the threaded rod 6. Then, the rubber ring 4 and the sealing plate 3 can be pulled to one side until the sealing plate 3 is removed from the sealing groove 2. This allows the rubber ring 4 to be removed from the oxygen mask body 1 and replaced. When replacing, the sealing plate 3 on one side of the rubber ring 4 can be inserted into the sealing groove 2. At the same time, the threaded rod 6 can be used to check the through hole 8 on the second fixing plate 7. Then, the nut 9 can be screwed into the threaded rod 6 until the nut 9 is tightly fixed to the second fixing plate 7. This allows the rubber ring 4 to be replaced and installed. This device can effectively disassemble and replace the rubber ring 4.

[0025] Specific working principle: When the rubber ring 4 is damaged, the nut 9 can be rotated so that one end of the nut 9 is no longer tightly fixed to the second fixing plate 7 and can be removed from the threaded rod 6. Then, the rubber ring 4 and the sealing plate 3 are pulled to one side until the sealing plate 3 is removed from the sealing groove 2. This allows the rubber ring 4 to be removed from the oxygen mask body 1 and replaced. When replacing, the sealing plate 3 on one side of the rubber ring 4 can be inserted into the sealing groove 2. At the same time, the threaded rod 6 can be used to observe the through hole 8 on the second fixing plate 7. Then, the nut 9 is screwed into the threaded rod 6 until the nut 9 is tightly fixed to the second fixing plate 7. This allows the rubber ring 4 to be replaced and installed. This device can effectively disassemble and replace the rubber ring 4.
