Description

Technical Field

[0001] This utility model relates to the field of respiratory equipment technology, and in particular to an anti-open mouth and nose pillow. Background Technology

[0002] A nasal pillow is a device used to assist respiratory therapy or improve sleep breathing. In the medical field, it is commonly used in non-invasive ventilation therapy, such as continuous positive airway pressure (CPAP) devices used for patients with sleep apnea-hypopnea syndrome. Nasal pillows are usually made of soft materials and are characterized by their small size and light weight. When worn, they only cover the nostrils, resulting in relatively low pressure on the face and a more comfortable experience for the user.

[0003] Patients using nasal pillows need to breathe through their mouths while sleeping to ensure the effectiveness of the ventilator. However, most products on the market no longer use nasal pillows to prevent patients from opening their mouths, instead using oronasal masks. For example, Philips' Dreamwear Full Face oronasal mask covers both the mouth and nose, providing both mouth-opening protection and positive pressure ventilation. However, this type of oronasal mask covers a larger area of ​​the face, creating more pressure during sleep, and is not as lightweight and comfortable as a nasal pillow. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nose pillow that prevents the mouth from opening, which is lightweight and comfortable, and also has the function of preventing the mouth from opening. It covers a smaller area of ​​the face and has a weaker feeling of pressure.

[0005] The technical solution adopted by this utility model is: to provide an anti-mouth and nose pillow, including...

[0006] An anti-mouth-opening headband includes a first strap for supporting the chin, a second strap and a third strap that cross over the head; the second and third straps are connected to the first strap at their intersection; and the first strap has symmetrical fixing devices on both sides corresponding to the cheek area.

[0007] The nasal pillow includes an air supply tube for connecting to an external ventilator, an air cushion for pressing against the nostrils, and connectors for airflow into each nostril. Both connectors are connected to the inner cavity of the air cushion. The inner cavity of the air cushion has several exhaust holes that communicate with the external atmosphere. Each of the two transverse sides of the air cushion is symmetrically connected to an air duct. The two air ducts pass through a fixing device on the same side and finally converge at the chin fixing part of the first strap, and are connected to the air supply tube.

[0008] To further optimize this technical solution, a nasogastric tube passage opening is provided on the outer side of the air cushion facing away from the nostril, and an elastic sealing ring is provided inside the nasogastric tube passage opening; the elastic sealing ring is used to keep the nasogastric tube passage opening and the nasogastric tube sealed when the nasogastric tube passes out through the connector, air cushion and nasogastric tube passage opening; a sealing cap with a snap-fit ​​fit is provided on the outside of the nasogastric tube passage opening.

[0009] To further optimize this technical solution, the fixing device includes a guide groove with an arc-shaped cross-section; the air guide pipe is interference-fitted with the guide groove.

[0010] To further optimize this technical solution, both the second and third straps are equipped with tension adjustment mechanisms.

[0011] To further optimize this technical solution, a flexible support shell is connected to the position where the first strap contacts and engages with the chin. Above the flexible support shell, a fourth strap is provided at the position where it engages with the lower lip. The two ends of the fourth strap are connected to the first strap.

[0012] To further optimize this technical solution, the tension adjustment mechanism is a snap-fit.

[0013] To further optimize this technical solution, the tension adjustment mechanism is an adhesive chain.

[0014] Compared with existing mouth and nose mask headbands, this utility model organically combines the nasal pillow and the mouth opening fixation strap, reducing the amount of strap used and optimizing the position of the nasal pillow air tube and air supply tube, so that the air tube and air supply tube pass through the cheek side and connect to the outside from the chin side, making it easy to wear, reducing the area of ​​the face covered, and reducing the patient's discomfort.

[0015] Existing nasal pillows or oronasal masks often cause air leakage when the nasogastric tube exits through the nostril due to crowding and interference with the nasal pillow connector. This also results in significant discomfort from the supported nostril. In this invention, for patients using a lower-entry nasogastric tube, the tube can exit through a connector, an air cushion, and a tube insertion opening, with an elastic sealing ring preventing air leakage. This design does not interfere with the patient's nasogastric feeding.

[0016] Other technical effects of this utility model will be clearly explained in the details of some embodiments. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, a mouth and nose protection pillow is provided, including...

[0024] An anti-mouth-opening headband includes a first strap 1 for supporting the chin, a second strap 2 and a third strap 3 for wrapping around the head and connecting in a crisscross pattern; the second strap 2 and the third strap 3 are connected to the first strap 1 at their intersection; the first strap 1 has symmetrical fixing devices on both sides corresponding to the cheek area;

[0025] The nasal pillow includes an air supply tube 4 for connecting to an external ventilator, an air cushion 5 for pressing against the nostrils, and connectors 6 for allowing air to flow into each nostril. Both connectors 6 are connected to the inner cavity of the air cushion 5. The inner cavity of the air cushion 5 is provided with several exhaust holes 7 that communicate with the external atmosphere. Each of the two transverse sides of the air cushion 5 is symmetrically connected to an air duct 8. The two air ducts 8 pass through a fixing device on the same side and finally converge at the chin fixing part of the first strap 1, and are connected to the air supply tube 4.

[0026] The two air ducts 8 serve both as air intake channels to supply air to the air cushion 5 and as connectors to press the air cushion 5 tightly against the nostrils. Adjusting the position of the air ducts 8 in the fixing device can adjust the pressure between the air cushion 5 and the nostrils, ensuring a seal between the connector 6 and the nostrils. The fixing device is a higher-level concept and can be a device such as an elastic buckle, adhesive, or elastic sleeve to fix the air ducts 8 to the first strap 1.

[0027] The connection point between the air supply tube 4 and the two conduits is located in the middle of the first band 1 corresponding to the chin. This way, neither the air supply tube 4 nor the two conduits 8 pass directly across the face, resulting in less visual pressure and greater flexibility of movement.

[0028] like Figure 3 , Figure 4As shown, in a further optimized embodiment, the outer side of the air cushion 5 facing away from the nostril is provided with a nasogastric tube passage 9, and an elastic sealing ring 10 is provided inside the nasogastric tube passage 9; the elastic sealing ring 10 is used to keep the nasogastric tube passage 9 and the nasogastric tube sealed when the nasogastric tube passes through the connector 6, the air cushion 5 and the nasogastric tube passage 9; a sealing cap 11 is provided on the outside of the nasogastric tube passage 9 for fastening.

[0029] Nasogastric tubes come in different sizes, therefore a flexible sealing ring 10 is needed to seal the gap between the nasogastric tube and the nasogastric tube passage 9. When the patient is not using a nasogastric tube, the sealing cap 11 is used to completely close the nasogastric tube passage 9.

[0030] In a further optimization of this embodiment, the fixing device includes a guide groove 12 with an arc-shaped cross-section; the air guide pipe 8 is interference-fitted with the guide groove 12.

[0031] The air guide tube 8 can be removed from the guide groove 12, adjusted for tightness, and then snapped back into the guide groove 12. Figure 1 As shown, the guide groove 12 has a rounded corner transition when it turns from the cheek side to the front of the face, which can prevent dead corners in the air tube 8.

[0032] In a further optimization of this embodiment, both the second strap 2 and the third strap 3 are equipped with tension adjustment mechanisms.

[0033] The first strap 1, the second strap 2, and the third strap 3 can all be made of elastic materials, such as silicone or elastic woven material. On this basis, adding a tension adjustment mechanism can expand the range of use for different patients. The tension adjustment device can be a buckle 15, Velcro, or Hook and loop.

[0034] To further optimize this embodiment, a flexible support shell 13 is connected to the position where the first strap 1 contacts and engages with the chin. Above the flexible support shell 13, a fourth strap 14 is provided at the position where it engages with the lower lip. Both ends of the fourth strap 14 are connected to the first strap 1.

[0035] The flexible support shell 13 fits snugly against the chin, conforming to ergonomics, increasing the contact area, and reducing discomfort on the chin. The fourth strap 14 prevents the flexible support shell 13 from slipping backward.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
