Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a face mask with a bite-sized opening. Background Technology

[0002] Currently, there are two common types of mouthpiece-equipped masks used for breathing in anesthetized patients. The first type is a fixed mouthpiece and mask. The second type is a lateral (i.e. axial) sliding connection between the mouthpiece and the mask. This type of connection allows for adjustment of the length of the mouthpiece extending into the mask to meet the bite requirements of different human mouth shapes.

[0003] However, due to the different shapes and positions of the human mouth, nose, and chin, such as the varying heights of the chin and nose (some people have high nose bridges and short chins, while others have short noses and long chins), the following problems arise when using the aforementioned mask: because the mask's bite is not designed to adapt to the different oral cavity structures of different people, it is impossible to ensure that the bite is aligned with the human mouth when wearing it, resulting in poor mask placement and discomfort in the patient's bite. Utility Model Content

[0004] In view of this, the present invention aims to provide a face mask with a bite opening, which can adapt to different mouth, nose and chin positions of different people, so that the bite opening can be directly facing the mouth of the human body, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A face mask with a bite-shaped opening includes a cup and a bite-shaped opening. A through hole is provided in the lower part of the cup. The diameter of the through hole is larger than the diameter of the bite-shaped opening. The bite-shaped opening passes through the through hole. The bite-shaped opening and the through hole are sealed and connected by an elastic sealing gasket. The root of the bite-shaped opening that extends into the cup is connected to the cup by an elastic bracket.

[0007] Furthermore, the diameter of the through hole is larger than the diameter of the bite.

[0008] Furthermore, the elastic sealing gasket includes an inner ring body, a first intermediate ring body, and an outer ring body arranged sequentially from the inside to the outside. The end faces of the inner ring body and the outer ring body are both planar structures, while the first intermediate ring body is a curved structure.

[0009] The inner ring body is fitted with a bite joint and bonded together, and the end face of the outer ring body is attached to and bonded to the surface of the cup.

[0010] Furthermore, the elastic support includes a second intermediate ring body positioned opposite the through hole of the bra cup, and several support legs positioned around the second intermediate ring body. The support legs are elastic support legs. The second intermediate ring body is connected to the bra cup through the support legs, and the second intermediate ring body is fitted with a fixed bite.

[0011] Furthermore, the second intermediate ring is an elastic intermediate ring, and the second intermediate ring is tightly fitted into the fixed jaw.

[0012] Furthermore, the support leg is provided in three parts, one of which is located directly above or below the bite, and the other two are symmetrically arranged on the left and right sides of the bite.

[0013] Furthermore, the front of the cup is provided with an air bladder along the periphery, and the air bladder is provided with an air nozzle.

[0014] Furthermore, the air nozzle is located on the back of the airbag.

[0015] Furthermore, the surface of the bite-in portion extending into the cup is covered with a soft material layer.

[0016] Compared with existing technologies, the face mask with a bite-shaped opening described in this utility model has the following advantages:

[0017] In this invention, the bite and the mask are connected by an elastic sealing gasket and an elastic bracket. On the one hand, this ensures the seal when the mask is worn. On the other hand, the bite posture and position can be adapted to different mouth, nose and chin positions, so that the bite is aligned with the oral cavity, improving the patient's bite comfort and enhancing the wearing and use effect of the mask.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 As shown, a face mask with a bite-shaped opening includes a cup 1 and a bite-shaped opening 2. The bite-shaped opening 2 has a tubular structure. A through hole is opened in the lower middle part of the cup 1. The bite-shaped opening 2 extends horizontally through the through hole into the cup 1. At this time, the front end of the bite-shaped opening 2 is located inside the cup 1, and the rear end is left outside the cup 1. The bite-shaped opening 2 and the through hole are sealed and connected by an elastic sealing gasket 5. The root of the part of the bite-shaped opening 2 that extends into the cup 1 is connected to the cup 1 by an elastic bracket 3, so that the bite-shaped opening 2 can be stably placed inside the cup 1. The setting of the elastic sealing gasket 5 and the elastic bracket 3 allows the position and posture of the bite-shaped opening 2 to adapt to the position of the patient's oral cavity, so that the bite-shaped opening 2 is directly facing the human oral cavity, ensuring the patient's biting comfort and improving the wearing and use effect of the face mask.

[0026] In this invention, the diameter of the through hole in the cup 1 is preferably larger than the diameter of the bite 2, and the elastic sealing gasket 5 is made of rubber or silicone. The structure and principle of the elastic sealing gasket 5 are similar to those of a diaphragm structure, such as... Figure 3 As shown, the device includes an inner ring body 51, an outer ring body 52, and a first intermediate ring body 53 connecting the inner ring body 51 and the outer ring body 52. ​​The end faces of the inner ring body 51 and the outer ring body 52 are planar, while the first intermediate ring body 53 is curved. During installation, one end face of the outer ring body 52 is an adhesive end face 521, which adheres to the surface of the cup 1 and is bonded to it. The inner ring body 51 is fitted with and fixed to the bite 2. To improve the stability and sealing of the connection between the elastic sealing gasket 5 and the bite 2, the inner surface 511 of the inner ring body 51 is bonded to the bite 2. The elastic sealing gasket 5 is itself an elastic component. The first intermediate ring body 53 adopts a curved structure, which facilitates axial and radial adjustment of the bite 2 position, ensuring that the bite 2 position can be adjusted according to different human oral cavity conditions and that the bite 2 extends into the oral cavity at an appropriate length.

[0027] In this utility model, the elastic support 3 includes a second intermediate ring 31 disposed opposite to the through hole of the cup 1, and several legs 32 disposed around the second intermediate ring 31. The legs 32 are belt structures. Both the second intermediate ring 31 and the legs 32 are elastic components, such as rubber or silicone components. The second intermediate ring 31 is tightly fitted with the bite 2. The second intermediate ring 31 is connected to the cup 1 through the several legs 32.

[0028] In this invention, the multiple legs 32 can be arranged evenly in a circumferential direction or in a symmetrical arrangement.

[0029] When arranged symmetrically, if there are 2n support legs 32, where n≥2, the support legs 32 are divided into two groups and symmetrically arranged on both sides of the bite opening 3. If there are 2n+1 support legs, where n≥1, one of the support legs can be placed directly above or below the bite opening 2, and the remaining support legs are divided into two groups and symmetrically arranged on both sides of the bite opening 2. This symmetrical arrangement of the support legs is suitable for most human facial needs, preventing the bite opening 2 from tilting to the left or right after insertion into the mouth.

[0030] In this invention, the front of the cup 1, corresponding to the face, is provided with an airbag 4 along its periphery. The airbag 4 is preferably a rubber airbag, and an air nozzle 6 is provided on the back of the airbag 4. When worn, air is supplied to the airbag 4 through the air nozzle 6, causing the airbag 4 to inflate. The airbag 4 fits snugly against the face, reducing discomfort and improving the seal between the mask body 1 and the face.

[0031] In this invention, the surface of the portion of the bite opening 2 that extends into the cup 1 is covered with a soft material layer, such as a silicone layer, a PVC layer, or a PU layer. When the patient wears the mask and bites, the soft material layer on the bite opening 2 protects the patient's teeth.

[0032] When wearing this mask, cup 1 should face the face of the anesthetized patient. Adjust the position of the bite 2 according to the position of the patient's mouth so that the front end of bite 2 (the end facing the mouth) is facing the patient's mouth. Insert bite 2 into the mouth while wearing the mask, and then connect the rear end of bite 2 to the breathing tube of the anesthesia ventilator.

[0033] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
