Description

Technical Field

[0001] This utility model relates to the field of oral closure technology, specifically to an oral closure device for patients who breathe through their mouths. Background Technology

[0002] Clinically, patients who are in a coma after a tracheotomy often maintain a persistently open-mouth state, which easily leads to dryness of the oral cavity, thickening of the tongue coating, and dryness and cracking of the lips and mouth. Furthermore, the retention of oral secretions allows for the proliferation of bacteria, easily causing oral complications such as halitosis, swollen and bleeding gums, and oral ulcers. Currently, the primary clinical practice is to use adhesive tape to seal the patient's lips together to prevent the mouth from remaining open during a coma.

[0003] Patent CN219461566U discloses an oral closure device comprising two horizontally oriented support plates. A horizontal plate is bolted between the two support plates near their top and bottom. An arc-shaped cushion is positioned between the two horizontal plates. A flexible patch is located on the front side of the arc-shaped cushion, and an elliptical opening is formed on the front side of the flexible patch. Elastic bands are connected to both sides of the flexible patch, with the sides of the elastic bands furthest from the flexible patch connected to the sidewalls of the two support plates. Through the interaction of the elastic bands, flexible patch, and other components, the patient's head can be adjusted and fixed in a suitable position, providing secondary fixation and effectively improving stability, thus preventing dislodgement.

[0004] However, this oral closure device has the following drawbacks: 1. It can only close the patient's mouth, not their teeth. When used on a comatose patient, the patient may unconsciously bite their tongue; 2. It mainly uses a patch to fix the oral closure device around the patient's lips, but patients with sensitive or allergic skin around their lips cannot use this device; 3. It can only close the patient's mouth, making it inconvenient to reopen the mouth for oral cleaning. If a comatose patient does not clean their mouth for a long time, it can easily lead to bad breath and a series of other problems. Utility Model Content

[0005] In view of the above-mentioned problems, the present invention aims to provide an oral closure device for patients who breathe through their mouths, so as to at least solve the problems of low comfort and troublesome disassembly of oral closure devices in the prior art, which prevent patients from cleaning their mouths for a long time.

[0035] like Figure 1 As shown, this application discloses an oral cavity closure device for patients who breathe through their mouths, including: an upper dental brace 10 and a lower dental brace 20. The upper surface of the upper dental brace 10 and the lower surface of the lower dental brace 20 are both provided with a first groove for engaging the teeth. It also includes: a lip closure device 30 and a jaw support 40. The lip closure device 30 is bonded and fixed to the outside of the upper dental brace 10 and the lower dental brace 20. The upper dental brace 10 and the lower dental brace 20 form an integral structure that can be placed directly inside the patient's mouth. The lip closure device 30 is made of rubber and can be gently bent to engage with the patient's lips. It uses downward and upward pressure on the upper and lower lips respectively to close the patient's lips. The jaw support 40 is used to support the patient's mandible.

[0036] Furthermore, such as Figure 6 As shown, the jaw support 40 includes: a lower jaw cover 41, two connecting straps 42, and two ear covers 43; one end of each of the two connecting straps 42 is connected to the top of the lower jaw cover 41 on both sides; the two ear covers 43 are connected to the other end of each of the connecting straps 42; by putting the ear covers 43 on the patient's ears and lifting the patient's jaw to make the patient's chin upward, the lower teeth can be lifted upward when the patient's chin is lifted, so that the teeth can bite within the upper jaw cover 10 and the lower jaw cover 20, improving the stability of the patient's teeth when closing and preventing the patient's teeth from opening. Example 2

[0037] Based on Embodiment 1, in order to enable the patient's mouth to open and avoid a series of problems such as bad breath caused by the patient keeping their mouth closed for a long time and not cleaning it, Embodiment 2 further provides an oral cavity opening and closing mechanism 50 for opening or closing the mouth. The upper and lower ends of the oral cavity opening and closing mechanism 50 are respectively connected to the upper dental brace 10 and the lower dental brace 20.

[0038] Furthermore, such as Figure 2As shown, the oral cavity opening and closing mechanism 50 includes: an upper dental support 51, a lower dental support 52, and a rotating shaft 53; the lower surface of the upper dental bracket 10 and the upper surface of the lower dental bracket 20 are both provided with a second groove, and two first fixing members are provided in the second groove of the upper dental bracket 10. The two first fixing members are matched with the width of the upper dental support 51, and the two first fixing members are rotatably connected to the upper dental support 51 through a damped small rotating shaft; two second fixing members are provided in the second groove of the lower dental bracket 20. The two second fixing members are matched with the width of the lower dental support 52, and the two second fixing members are rotatably connected to the lower dental support 52 through a damped small rotating shaft; the adjacent ends of the upper dental support 51 and the lower dental support 52 are both sleeved on the damped rotating shaft 53; there is a certain horizontal distance between adjacent first fixing members and second fixing members to avoid the upper dental support 51 and the lower dental support 52 overlapping when rotating, which would cause the upper dental bracket 10 and the lower dental bracket 20 to be unable to close.

[0039] Furthermore, such as Figure 3 As shown, the lip closure device 30 includes: a closure element 31 and two push rods 32; as Figure 4 As shown, the ends of the two pushers 32 away from the closure member 31 are respectively sleeved on both ends of the rotating shaft 53 and are interference-fitted with the rotating shaft 53, that is, the pushers 32 and the rotating shaft 53 cannot achieve relative movement; the second grooves on the lower surface of the upper brace 10 and the upper surface of the lower brace 20 are hollowed out near the sides of the pushers 32, so that when the upper brace 10 and the lower brace 20 are closed, the two pushers 32 can extend out of the oral cavity from the hollowed-out parts; the closure member 31 is mushroom-shaped and made of rubber, and its two ends are respectively connected to the two pushers 32. When the closure member 31 contacts the patient's lips, the upper end of the closure member 31 is slightly bent downward and the lower end of the closure member 31 is slightly bent upward. By applying downward pressure to the upper lip and upward pressure to the lower lip, the patient's lips are closed.

[0040] The oral cavity closing device for patients breathing through their mouths provided in this utility model allows for the specific operation of closing the mouth of a comatose patient as follows:

[0041] like Figure 5 As shown, the closure element 31 is pushed towards the oral cavity side, while the upper tooth support 51 rotates clockwise and the lower tooth support 52 rotates counterclockwise until they are parallel, and the pivot 53 is placed inside the oral cavity. The push rod 32 passes through the cutout of the upper tooth bracket 10 and the lower tooth bracket 20, and the closure element 31 is close to and fits the patient's lips. Then, the upper end of the closure element 31 is slightly bent downward and the lower end of the closure element 31 is slightly bent upward. By applying downward pressure to the upper lip and upward pressure to the lower lip, the patient's lips are closed. Finally, the mandibular sleeve 41 is placed on the patient's mandible, and the two ear sleeves 43 are placed on the patient's ears, so that the patient's chin is lifted, improving the stability of the patient's teeth when closed.

[0042] The oral cavity closing device for patients breathing through their mouths provided in this utility model allows for the opening of the mouth of unconscious patients and the cleaning of the oral cavity. The specific operation of this device is as follows:

[0043] Remove the two ear covers 43 from the patient's ears and the chin cover 41 from the patient's chin; then gently pry the upper end of the closure 31 upwards and the lower end of the closure 31 downwards to relieve pressure on the patient's lips; Figure 4 As shown, the closure 31 is pulled outwards from the mouth, while the upper tooth support 51 rotates counterclockwise and the lower tooth support 52 rotates clockwise to 180 degrees, thus opening the braces to their maximum angle. The patient's mouth is then cleaned.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
