Description

Technical Field

[0001] This utility model relates to medical assistive devices, and more particularly to a medical oral assistive device. Background Technology

[0002] Regular oral care can maintain oral health, reduce the incidence of oral diseases, promote digestion and nutrient absorption, and improve comfort. Furthermore, for patients who are bedridden for extended periods, it can help prevent respiratory infections and prevent oral bacteria and viruses from reaching the lungs through inhalation.

[0003] In oral care, for children and patients who are unable to care for themselves due to impaired consciousness, endotracheal intubation, hemiplegia, coma, or other conditions, oral care is primarily performed using tongue depressors and mouth speculum inserted through the molars to expand the oral cavity. Furthermore, the same methods are typically used for oral examinations, sputum suction, and specimen collection.

[0004] Using tongue depressors and mouth diffusers has the following main drawbacks:

[0005] 1. May cause mechanical damage to the oral cavity: During the use of tongue depressors and mouth speculum, patients with impaired consciousness or who are uncooperative may resist the tongue depressors or mouth speculum by biting their teeth or resisting with their tongues. This can easily cause damage to the oral mucosa, bleeding gums, etc., thereby reducing the efficiency of oral diagnosis, oral care and other related operations.

[0006] 2. Limited function: Tongue depressors and mouth speculum can only be used to observe the condition of the throat, fix the tongue to prevent tongue biting, and assist in collecting samples such as saliva, oral and throat secretions.

[0007] 3. Limited target audience: Most procedures require a high degree of cooperation from the individual to complete the examination. For conscious children, the elderly, and people with impaired consciousness, fear or discomfort during the treatment process often leads to unconscious resistance and non-cooperation. Usually, two or more staff members are needed to complete the procedure, or the procedure may still fail. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a medical oral aid that is simple in structure, easy to operate, widely applicable, highly safe to use, and easy to carry.

[0009] Compared to the shortcomings of tongue depressors and mouth expanders, this invention designs a medical oral assistive device. It uses the supporting force of the buccinator muscles, a disposable replaceable occlusal pad installed at the end of the upper and lower mouth expander arms to hold the tongue and teeth in place, and a limiting and locking mechanism to control the size of the mouth opening, providing the space required for treatment. This allows the patient to maintain the desired mouth opening angle for an extended period in a relatively comfortable manner. The specific solution is as follows:

[0010] The medical oral assist device described in this solution includes: an upper connector, a lower connector, and several disposable replacement occlusal pads; each disposable replacement occlusal pad is provided with a detachable connecting component one at its tail; the upper connector is integrally formed of an upper expansion arm and an upper handle; the lower connector is integrally formed of a lower expansion arm and a lower handle; both the end of the upper expansion arm and the end of the lower expansion arm are provided with detachable connecting components two; any detachable connecting component one and any detachable connecting component two can form a detachable connection structure connecting two corresponding parts;

[0011] The area where the upper expansion arm and the upper handle meet is the first area, and the area where the lower expansion arm and the lower handle meet is the second area. The first area and the second area are hinged together. A limiting locking mechanism is provided between the upper handle and the lower handle to open the upper expansion arm and the lower expansion arm outward and lock them at a specified opening angle.

[0012] A lighting component is provided on the upper or lower expansion arm. The lighting component can broaden the operator's field of vision, enabling the operator to observe the intraoral condition more clearly and improve the efficiency of diagnosis and treatment.

[0013] Furthermore, in the aforementioned medical oral assistive device, the limiting and locking mechanism comprises: a limiting seat, a limiting rod, a spring, and a lever; the limiting rod is a hexagonal prism structure, and the lever is integrally formed by a locking plate and a pressing plate, with a diamond-shaped through hole on the locking plate; the bottom of the limiting seat is hinged to the lower handle, and the top of the limiting rod is hinged to the upper handle; a mounting hole is provided on the top of the limiting seat, and one side of the top of the limiting seat extends upward to form a protrusion with an inner groove; the end of the locking plate is engaged in the groove; the limiting rod passes through the diamond-shaped through hole and the spring and then extends into the mounting hole; under the elastic force of the spring, the locking plate tilts, causing the diamond-shaped through hole to engage the four sides of the limiting rod, thus locking the position of the limiting rod; when the position of the limiting rod is locked, a gap is left between the pressing plate and the limiting seat to unlock the limiting rod.

[0014] To better fit the area where the operator's fingers press, this design features an outwardly curved edge at the tail of the pressing plate, forming a smooth outer contour. It should be noted that, for ease of description, the side where the operator's fingers press is defined as the "outer side."

[0015] There are several forms of detachable connection structures. Two schemes are presented here. The first scheme is that both the first and second detachable connection components are mating or interlocking, and either the first or second mating component can be paired to form a mating pair. The second scheme is that the first detachable connection component is a screw, and the second detachable connection component is an internally threaded hole that matches the external thread section on the screw.

[0016] The disposable replaceable bite pad is preferably made of silicone.

[0017] Furthermore, in the aforementioned medical oral assistive device, the lighting component includes: a light-emitting diode, a button battery, and a switch, wherein the switch is a rocker switch or a self-locking button.

[0018] To provide a more comfortable grip for the operator's fingers on the upper and lower handles, this design includes a first raised edge at the end of the upper handle, forming a smooth outer contour, and a second raised edge at the end of the lower handle, also forming a smooth outer contour. It should be noted that, for ease of description, the side where the operator's fingers grip is defined as the "outer" side.

[0019] The beneficial effects of this utility model are: ① The limiting and locking mechanism can gradually adjust the degree of the patient's mouth opening as needed, improving human adaptability and allowing the patient to maintain the mouth opening angle for a long time in a relatively comfortable situation, thereby improving the efficiency of diagnosis and treatment and nursing care; ② The above-mentioned medical oral assistive device can play a role in oral care, diagnosis and treatment, preventing tongue biting during epileptic seizures, assisting in sputum suction, assisting in the treatment of oral diseases, mouth opening training, and improving the efficiency of oral specimen collection. It can be used in hospitals or by patients at home, and is convenient to carry and has a wide range of applications; ③ The use of disposable replaceable occlusal pads can reduce the chance of infection. In addition, the disposable replaceable occlusal pads are made of silicone, which has the advantages of being soft and not easily damaged, reducing mechanical damage to the oral cavity. Furthermore, due to the large contact area, it is easier to effectively hold the tongue and teeth, further reducing mechanical damage to the oral cavity; ④ The above-mentioned medical oral assistive device is simple to operate and the steps are simple. Even patients with impaired consciousness or who are uncooperative can complete the operation alone. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the medical oral assistive device described in this embodiment includes: an upper connector 1, a lower connector 2, and several disposable replacement occlusal pads 3. Each disposable replacement occlusal pad 3 has a detachable connecting component 1 61 at its tail. The upper connector 1 is integrally formed from an upper expansion arm 11 and an upper handle 12, and the lower connector 2 is integrally formed from a lower expansion arm 21 and a lower handle 22. Both the ends of the upper expansion arm 11 and the lower expansion arm 21 are provided with detachable connecting components 2 62. Each detachable connecting component 1 61 and each detachable connecting component 2 62 can form a detachable connecting structure 6 connecting two corresponding components.

[0031] This embodiment uses a disposable replaceable bite pad 3, which can reduce the chance of infection. In addition, the disposable replaceable bite pad 3 is made of silicone material, which has the advantages of being soft and not easily damaged, and can reduce mechanical damage to the oral cavity. Furthermore, due to its large contact area, it can more easily and effectively hold the tongue and teeth, further reducing mechanical damage to the oral cavity.

[0032] There are several forms of detachable connection structures. Two schemes are given here. The first scheme is that detachable connection component 61 is a male-female snap-fit ​​component, and detachable connection component 62 is a male-female snap-fit ​​component. Either male-female snap-fit ​​component 1 or either male-female snap-fit ​​component 2 can be paired to form a male-female snap-fit. The second scheme is that detachable connection component 61 is a screw, and detachable connection component 62 is an internally threaded hole that matches the external thread section on the screw. Of course, in actual manufacturing, the detachable connection structure is not limited to these two schemes.

[0033] The area where the upper expansion arm 11 and the upper handle 12 meet is the first area, and the area where the lower expansion arm 21 and the lower handle 22 meet is the second area. The first area and the second area are hinged together. A limiting and locking mechanism 5 is provided between the upper handle 12 and the lower handle 22 to open the upper expansion arm 11 and the lower expansion arm 21 outward and lock them at a specified opening angle.

[0034] like Figure 5 and Figure 6 As shown, the structure of the limiting locking mechanism 5 includes: a limiting seat 7, a limiting rod 51, a spring 9, and a lever plate; the limiting rod 51 is a hexagonal prism structure, and the lever plate is integrally formed by a locking plate 81 and a pressing plate 82, with a diamond-shaped through hole 84 on the locking plate 81; the bottom of the limiting seat 7 is hinged to the lower handle 22, and the top of the limiting rod 51 is hinged to the upper handle 12, with a mounting hole opening downward on the top of the limiting seat 7, and one side of the top of the limiting seat 7 extending upward to form a protrusion 71 with an inner groove, the end of the locking plate being engaged in the groove, and the limiting rod 51 passing through the diamond-shaped through hole 84 and the spring 9 and extending into the mounting hole. When the pressing plate 82 is not subjected to external force, the end of the locking plate is restricted by the locking groove and cannot disengage from it. Under the elastic force of the spring 9, the locking plate 81 can only tilt upward on the other side until the diamond-shaped through hole 84 locks the four sides of the limiting rod 51, locking the position of the limiting rod 51. At this time, the limiting rod 51 cannot move along its axial direction. When the position of the limiting rod 51 is locked, there is a gap between the pressing plate 82 and the limiting seat 7 to unlock the limiting rod 51. When unlocking, press the pressing plate 82 inward to gradually rotate the locking plate 81, which is in an inclined state, to a horizontal position. At this time, the diamond-shaped through hole 84 can no longer lock the four sides of the limiting rod 51. At this time, the limiting rod 51 can be pulled outward or pushed inward to adjust the axial position of the limiting rod 51.

[0035] To better fit the area where the operator's fingers press, this design includes an outwardly curved edge 83 at the tail of the pressing plate 82, forming a smooth outer contour. It should be noted that, for ease of description, the side where the operator's fingers press is defined as the outside.

[0036] To provide a more comfortable grip for the operator's fingers on the upper handle 12 and lower handle 22, this embodiment provides a first raised edge 13 with a smooth outer contour at the end of the upper handle 12, and a second raised edge 23 with a smooth outer contour at the end of the lower handle 22. It should be noted that, for ease of description, the side where the operator's fingers grip is defined as the "outer side".

[0037] A lighting assembly 4 is provided on the upper expansion arm 11 or the lower expansion arm 21, such as... Figure 7 As shown, the lighting component 4 includes: a light-emitting diode 41, a button battery 42, and a switch 43. The switch 43 is a rocker switch or a self-locking button, and can be positioned for easy access by the operator. The lighting component 4 can broaden the operator's field of vision, allowing them to observe the intraoral cavity more clearly and improving diagnostic and nursing efficiency.

[0038] The aforementioned medical oral assistive device is simple to operate and follows easy procedures. Even patients with impaired consciousness or who are uncooperative can be operated independently. During use, the limiting and locking mechanism 5 allows for gradual and as-needed adjustment of the patient's mouth opening, reducing discomfort, improving adaptability, and enabling the patient to maintain the required mouth opening angle for an extended period in a relatively comfortable manner, thereby improving the efficiency of diagnosis, treatment, and nursing care.

[0039] The aforementioned medical oral aids can serve functions such as oral care, diagnosis and treatment, prevention of tongue biting during epileptic seizures, assistance with sputum suction, assistance in the treatment of oral diseases, mouth opening training, and improvement of the efficiency of oral specimen collection. They can be used in hospitals or by patients at home, are easy to carry, and have a wide range of applications.
