Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oxygen mask restraint mechanism. Background Technology

[0002] An oxygen mask is a device that transfers oxygen from a storage tank into the lungs. There are mainly two types: medical oxygen masks and civilian aviation oxygen masks. They play an important role in assisting in the treatment of diseases and protecting the safety of flight attendants. When using an oxygen mask, an oxygen mask restraint mechanism is required.

[0003] Chinese patent document CN220833809U discloses an oxygen mask restraint mechanism, including an oxygen mask body and a fitting component disposed on the rear of the outer wall of the oxygen mask body. A support component is fixedly connected to the top of the oxygen mask body, and a locking component is snapped onto the inner wall of the support component. The locking component includes a limiting plate snapped onto the inner wall of the support component. The limiting plate is fixedly connected to both sides of the rear end face of the top plate. By adjusting the position of the top plate when locked, the position of the upper restraint component can be adjusted so that the restraint position of the upper restraint component can be fully adapted to the actual needs of the patient. An additional restraint component is added to the traditional oxygen mask, which on the one hand can prevent the oxygen mask body from falling off when the patient turns their head, improving the safety and stability of the restraint mechanism; on the other hand, it can also make the oxygen mask body fit the patient's face more closely, reducing oxygen waste.

[0004] The existing technology has the following problems:

[0005] The oxygen mask restraint mechanism cannot further ensure the stability of the mask during use, nor is it convenient to adjust it according to the patient's needs. The oxygen mask restraint mechanism cannot ensure a seal while improving the comfort of use, thus causing discomfort to the patient's face during prolonged use. Utility Model Content

[0006] This invention provides an oxygen mask restraint mechanism to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An oxygen mask restraint mechanism includes a mask, an oxygen tube fixedly installed on the left side of the mask, a connector fixedly connected to the end of the oxygen tube, a sealing gasket fixedly connected to the lower surface of the mask, an auxiliary fixing component fixedly connected to the inner cavity of the right part of the mask, and head straps fixedly installed on the front and rear sides of the mask.

[0009] Preferably, the auxiliary fixing component includes an arc-shaped fixing plate, a fixing column is fixedly connected to the inner cavity in the middle of the arc-shaped fixing plate, an annular iron sheet is fixedly connected to the outer wall of the fixing column, and arc-shaped iron sheets are fixedly connected to both the left and right sides of the outer wall of the annular iron sheet.

[0010] Preferably, the sealing gasket includes a silicone pad, the upper surface of which is fixedly connected to the lower surface of the mask, and a sponge interlayer is fixedly connected to the top of the inner cavity of the silicone pad.

[0011] Preferably, an elastic pad is fixedly connected to the lower surface of the first sponge interlayer, and a second sponge interlayer is fixedly connected to the lower surface of the elastic pad. The lower surface of the second sponge interlayer is fixedly connected to the bottom of the inner cavity of the silicone pad.

[0012] Preferably, a smooth rubber strip is fixedly connected to the lower surface of the silicone pad, and a sealing inner ring is fixedly connected to the smooth rubber strip and the inner wall of the silicone pad.

[0013] Preferably, adjusting plates are fixedly connected to opposite sides of the two arc-shaped iron plates, and the outer walls of the two adjusting plates are movably sleeved with the inner cavities of the left and right portions of the arc-shaped fixed plate.

[0014] Preferably, elastic silicone rings are fixedly connected to the lower surfaces of the opposite portions of the two adjustment plates, and sponge pads are fixedly connected to the lower surfaces of the two elastic silicone rings.

[0015] Preferably, the lower surfaces of both sponge pads are fixedly connected with arc-shaped smooth rubber strips, the width of which is greater than that of the sponge pads.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] This utility model provides an oxygen mask restraint mechanism. By moving two adjusting plates, the two adjusting plates can move closer to each other under the action of two arc-shaped iron plates, thereby pushing two arc-shaped smooth rubber soft bands to clamp and fix the patient's nose. At the same time, the outer walls of the opposite parts of the two adjusting plates can be pinched and moved outward, thereby driving the two arc-shaped smooth rubber soft bands away from the patient's nose, so as to facilitate adjustment at any time as needed, and the operation is simple.

[0018] This invention provides an oxygen mask restraint mechanism. Through the action of sponge interlayer one and sponge interlayer two, the silicone pad can increase its softness. At the same time, under the action of the elastic pad, the lower surface of the smooth rubber band can be closely fitted to the patient's face, thereby maintaining a seal and improving comfort. In addition, through the action of the smooth rubber band, the silicone pad can closely fit the skin while providing protection, thereby ensuring a seal, preventing oxygen leakage, and reducing oxygen waste.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, an oxygen mask restraint mechanism includes a mask 1, an oxygen tube 2 fixedly installed on the left side of the mask 1, a connector 3 fixedly connected to the end of the oxygen tube 2, a sealing gasket 4 fixedly connected to the lower surface of the mask 1, an auxiliary fixing component 5 fixedly connected to the inner cavity of the right part of the mask 1, and a head strap 6 fixedly installed on the front and rear sides of the mask 1.

[0027] First, connect connector 3 to the oxygen equipment, then place mask 1 on the patient's face. The sealing pad 4 ensures that mask 1 fits snugly against the patient's face without causing discomfort. Next, secure headband 6 to the patient's head. Finally, with the help of auxiliary fixing component 5, mask 1 is further secured.

[0028] like Figure 2 As shown, the lower surfaces of the two sponge pads 57 are fixedly connected with arc-shaped smooth rubber strips 58, and the width of the arc-shaped smooth rubber strips 58 is greater than that of the sponge pads 57.

[0029] When the outer wall of the sponge pad 57 comes into contact with the patient's nasal skin, it can adhere closely to the skin while generating suction, thereby ensuring the stability of the fixation.

[0030] like Figure 3 As shown, the auxiliary fixing component 5 includes an arc-shaped fixing plate 51. A fixing post 55 is fixedly connected to the inner cavity of the middle part of the arc-shaped fixing plate 51. An annular iron sheet 54 is fixedly connected to the outer wall of the fixing post 55. Arc-shaped iron sheets 53 are fixedly connected to both the left and right sides of the outer wall of the annular iron sheet 54. Adjusting plates 52 are fixedly connected to the opposite sides of the two arc-shaped iron sheets 53. The outer walls of the two adjusting plates 52 are movably sleeved with the inner cavities of the left and right parts of the arc-shaped fixing plate 51.

[0031] By moving the two adjusting plates 52, they can be brought closer together under the action of the two arc-shaped iron plates 53, thereby pushing the two arc-shaped smooth rubber soft bands 58 to clamp and fix the patient's nose. At the same time, the outer walls of the opposite parts of the two adjusting plates 52 can be pinched and moved outward, thereby driving the two arc-shaped smooth rubber soft bands 58 away from the patient's nose, which makes it easy to adjust at any time according to the application needs, and the operation is simple.

[0032] The lower surfaces of the opposite parts of the two adjustment plates 52 are fixedly connected with elastic silicone rings 56, and the lower surfaces of the two elastic silicone rings 56 are fixedly connected with sponge pads 57.

[0033] The elastic silicone ring 56 and the sponge pad 57 enable the two adjusting plates 52 to push the two curved smooth rubber soft bands 58 to clamp and fix the patient's nose, providing a certain amount of cushioning and protection, thereby ensuring the stability of the fixation while improving comfort and reducing damage to the patient's face.

[0034] like Figure 4 As shown, a smooth rubber strip 43 is fixedly connected to the lower surface of the silicone pad 41, and a sealing inner ring 42 is fixedly connected to the smooth rubber strip 43 and the inner wall of the silicone pad 41.

[0035] The smooth rubber strip 43 allows the silicone pad 41 to fit snugly against the skin while providing protection, thus ensuring a seal, preventing oxygen leakage, and reducing oxygen waste.

[0036] like Figure 5 As shown, the sealing gasket 4 includes a silicone soft gasket 41, the upper surface of which is fixedly connected to the lower surface of the mask 1, and a sponge interlayer 44 is fixedly connected to the top of the inner cavity of the silicone soft gasket 41; an elastic gasket 45 is fixedly connected to the lower surface of the sponge interlayer 44, and a sponge interlayer 46 is fixedly connected to the lower surface of the elastic gasket 45; the lower surface of the sponge interlayer 46 is fixedly connected to the bottom of the inner cavity of the silicone soft gasket 41.

[0037] The silicone pad 41 is made softer by the sponge interlayer 44 and the sponge interlayer 46. At the same time, the elastic pad 45 ensures that the lower surface of the smooth rubber soft band 43 can fit closely to the patient's face, thereby maintaining a seal and improving comfort, making it easy to use.

[0038] The working principle of this utility model is as follows: First, the connector 3 is connected to the oxygen equipment. Then, the mask 1 is placed on the patient's face. The smooth rubber soft band 43 allows the silicone soft pad 41 to fit tightly against the skin while providing protection, thus ensuring a seal and preventing oxygen leakage. Furthermore, the sponge interlayer 44, the sponge interlayer 46, and the elastic pad 45 ensure that the patient's face does not feel uncomfortable. Next, the headband 6 is fixed to the patient's head. Finally, by moving the two adjusting plates 52, the two adjusting plates 52 can move closer to each other under the action of the two arc-shaped iron plates 53, thereby pushing the two arc-shaped smooth rubber soft bands 58 to clamp and fix the patient's nose, thus further fixing the mask 1.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
