Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a lightweight, padded-free medical nasal mask. Background Technology

[0002] like Figure 1 As shown, most existing medical nasal masks adopt a traditional two-layer structure. The outer body 1 is mainly used to connect with the headband 2 and the curved head 5, while the inner connector 4 is used to seal and cover the patient's mouth area and is connected to the silicone pad 3. However, this design has significant drawbacks: to improve the stability of the mask when worn by the patient, a forehead support structure is usually set on the outer body 1. This forehead support structure can seriously affect the patient's vision; moreover, the addition of the forehead support structure will inevitably increase the size of the outer body 1, resulting in a heavier overall weight for the nasal mask. When worn for a long time, the patient will feel uncomfortable due to the extra weight and restricted vision, which will significantly reduce the user experience and even adversely affect the treatment effect.

[0003] Furthermore, since the silicone pad 3 is made of ordinary silicone, it is not adhesive. Therefore, the connector 4 and the silicone pad 3 can only be bonded and fixed by applying adhesive, which makes the manufacturing process of the product complicated. Summary of the Invention

[0004] This application provides a lightweight, padded-free medical nasal mask to address the problems of existing nasal masks causing esotropia in patients and their heavy overall weight.

[0005] The technical solution of this utility model is as follows:

[0006] A lightweight, forehead-padless medical nasal mask includes: a silicone pad, a main body, a left fixation bracket, a right fixation bracket, a left adjustment buckle, a right adjustment buckle, and a headband;

[0007] The main components and silicone pads are self-adhesive;

[0008] After the main component and silicone pad self-adhere, it is used to cover the patient's nasal and oral areas;

[0009] The left and right fixed brackets are connected to the left and right sides of the main body respectively, and the left and right adjusting buckles are connected to the left and right sides of the main body respectively. The left fixed bracket is located above the left adjusting buckle, and the right fixed bracket is located above the right adjusting buckle.

[0010] The four ends of the headband are respectively connected and fixed to the left fixed bracket, the right fixed bracket, the left adjustment buckle, and the right adjustment buckle.

[0011] Preferably, the left fixation bracket and the left adjustment buckle are both connected to the left side of the main body, and the right fixation bracket and the right adjustment buckle are both connected to the right side of the main body. When the patient is wearing a medical ventilation nasal mask, the left fixation bracket is fitted to the face below the patient's left eye and is connected to the first end of the headband above the patient's left ear; the right fixation bracket is fitted to the face below the patient's right eye and is connected to the second end of the headband above the patient's right ear; the left adjustment buckle is fitted to the patient's left lower jaw and is connected to the third end of the headband on the patient's left neck; the right adjustment buckle is fitted to the patient's right lower jaw and is connected to the fourth end of the headband on the patient's right neck.

[0012] Preferably, the silicone pad is made of liquid silicone.

[0013] Preferably, the left and right fixed brackets are inserted into the main body component, and the left and right adjusting buckles are rotatably connected to the main body component.

[0014] The beneficial effects of this utility model are as follows:

[0015] This solution employs a self-adhesive fixing method between the main component and the silicone pad, which not only reduces the processing steps of the nasal mask but also optimizes the overall structure. After the main component and the silicone pad are bonded together, they tightly cover the patient's nasal and oral cavity areas while completely avoiding the eyes and the area between the eyes, thus preventing direct pressure on the eye structures and effectively preventing the occurrence of esotropia.

[0016] Furthermore, this design eliminates the traditional outer structure and forehead support of a mouth and nose mask, integrating the headband connection and the curved head assembly into the inner structure connector. This improvement significantly reduces the overall weight of the mouth and nose mask, making it lighter and thinner. Because the forehead support is eliminated, the patient's field of vision is no longer restricted, resulting in a wider field of vision, no pressure during wear, and no discomfort even after prolonged use, greatly improving the patient's wearing comfort and user experience.

[0018] Figure 2 This is a schematic diagram of the structure of the medical ventilation mouth and nose of this application. Detailed Implementation

[0019] Reference Figure 2 This application provides a lightweight, non-padded medical nasal mask, comprising: a silicone pad 1, a main body 2, a left fixation bracket 4, a right fixation bracket 5, a left adjustment buckle 6, a right adjustment buckle 7, and a headband 8.

[0020] The main body component 2 and the silicone pad 1 are self-adhesive. Self-adhesion means that the main body component 2 and the silicone pad 1 can adhere and bond through their own material properties or special surface treatments without the need for additional adhesives (such as glue), thereby reducing the processing steps of the medical ventilation nasal mask.

[0021] In this embodiment, the material of the silicone pad 1 is liquid silicone. Liquid silicone has self-adhesive properties, which allows the silicone pad 1 to be directly attached to the main component 2, thereby reducing the processing step of applying adhesive to the silicone pad 1 in the manufacturing process.

[0022] After self-adhesion, the main component 2 and the silicone pad 1 cover the patient's nasal and oral regions, including the bridge of the nose, nasal alae, nasal vestibule, upper lip, lower lip, and perioral area. The soft silicone pad 2 conforms closely to the patient's facial contours, forming a good seal and ensuring effective airflow transmission and management. Because the main component 2 and the silicone pad 1 completely avoid the area between the eyes and both eyes, they do not exert direct pressure on the eye structures, thus preventing esotropia (inward strabismus).

[0023] The left fixed bracket 4 and the right fixed bracket 5 are respectively connected to the left and right sides of the main body component 2, and the left adjusting buckle 6 and the right adjusting buckle 7 are respectively connected to the left and right sides of the main body component 2. The left fixed bracket 4 is located above the left adjusting buckle 6, and the right fixed bracket 5 is located above the right adjusting buckle 7.

[0024] Specifically, the left fixation bracket 4 and the left adjustment buckle 6 are both connected to the left side of the main body component 2, and the right fixation bracket 5 and the right adjustment buckle 7 are both connected to the right side of the main body component 2. When the patient is wearing a medical ventilation nasal mask, the left fixation bracket 4 is fitted to the patient's face below the left eye and connected to the first end 81 of the headband 8 above the patient's left ear; the right fixation bracket 5 is fitted to the patient's face below the right eye and connected to the second end 82 of the headband 8 above the patient's right ear; the left adjustment buckle 6 is fitted to the patient's left lower jaw and connected to the third end 83 of the headband 8 on the left side of the patient's neck; the right adjustment buckle 7 is fitted to the patient's right lower jaw and connected to the fourth end 84 of the headband 8 on the right side of the patient's neck. After being connected to the left fixation bracket 4 and the right fixation bracket 5, the headband 8 is fixed around the user's forehead, thereby reducing pressure on the forehead and further reducing biocompatibility risks. Furthermore, it effectively avoids the patient's primary line of sight, playing a positive and important role in preventing esotropia.

[0025] Combined with appendix Figure 1 and 2As can be seen, by changing the connection position between the headband and the main body, the main body in this embodiment can eliminate the existing outer structure and forehead pad design, and place the headband connection and the elbow head installation position on the original inner structure connector, thereby reducing the overall weight of the nasal mask. Through testing, the applicant measured the overall weight of the medical nasal mask in this application to be approximately 88g, making it lightweight and comfortable for patients to wear, and its weight is significantly lower than... Figure 1 The existing products are about 1 / 4 lighter.

[0026] In this embodiment, the left fixed bracket 4 and the right fixed bracket 5 are assembled on the main body component 2 by plugging in, while the left adjusting buckle 6 and the right adjusting buckle 7 are rotatably connected to the main body component 2.

[0027] The main body component 2 integrally incorporates: a first slot 21 connected to the left fixed bracket 4, a second slot 22 connected to the right fixed bracket 5, a first rotating shaft 23 connected to the left adjusting buckle 6, and a second rotating shaft 24 connected to the right adjusting buckle 7. Through this integral molding, the first slot 21, the second slot 22, the first rotating shaft 23, and the second rotating shaft 24 become a single unit with the main body component 2, reducing assembly gaps and the possibility of loosening between components. This ensures reliable performance of the equipment during use. The integral molding design also reduces assembly steps in the production process, lowering labor and time costs.

[0028] like Figure 2 In this embodiment of the application, the lightweight medical nasal mask without forehead pad also includes: a bent tube head 3; an airway interface 21 is provided on the main body device 2, and one end of the bent tube head 3 is connected to the airway interface 21 by means of screw connection or the like.

[0029] Reference Figure 2 The medical nasal mask also includes: a left support sleeve 9 and a right support sleeve 10; the left support sleeve 9 is fitted onto the left fixation bracket 4; and the right support sleeve 10 is fitted onto the right fixation bracket 5. The left support sleeve 9 and the right support sleeve 10 are made of softer materials such as rubber, which helps to conform to the patient's face and avoids the discomfort caused by the relatively harder materials of the left fixation bracket 4 and the right fixation bracket 5.

[0030] Considering that the width of the left fixation bracket 4 and the right fixation bracket 5 is too narrow, the patient may feel excessive pressure due to the small contact area with the patient's face. Therefore, in this embodiment, the left fixation bracket 4 and the right fixation bracket 5 are made wider to increase the contact area with the patient's face, thereby reducing the patient's discomfort.

[0031] In this embodiment, the left fixing bracket 4 and the right fixing bracket 5 are made of PP material through injection molding with a custom mold, and undergo processes such as baking / curing / thermoplasticizing / demolding / trimming.
