Description

Technical Field

[0001] The utility model relates to the technical field of tooth pads, in particular to a tooth pad. Background Art

[0002] In the treatment of mental illness, electroconvulsive therapy is a widely used method, especially for patients with schizophrenia and epilepsy. This therapy achieves therapeutic effects by giving patients an appropriate amount of electric current stimulation. However, during the treatment, the patient's upper and lower jaws will be tightly clenched under the effect of electric shock, which brings a potential safety issue: the patient may injure the mouth or tongue due to excessive biting force.

[0003] To prevent this kind of injury, it is common practice for patients to put a bite block in their mouths during electroconvulsive therapy. This bite block can provide a buffer layer between the patient's upper and lower teeth, thereby reducing or avoiding damage to the mouth or tongue caused by clenching the jaws.

[0004] However, there is often a problem with existing dental pad designs: although patients will clench their teeth when receiving electric shocks, they can open their mouths at other times, such as when waiting for treatment or after treatment. Due to fear, anxiety and other reasons, patients may accidentally drop the dental pads, which not only affects the treatment effect, but also may cause safety hazards. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a tooth pad, such as Figure 1-Figure 4 As shown, it includes a lower sleeve 1 and an upper sleeve 2, and both of the lower sleeve 1 and the upper sleeve 2 are U-shaped to match the shape of the upper and lower rows of teeth to ensure that they fit the arrangement of the teeth. The two ends of the lower sleeve 1 and the upper sleeve 2 are rotatably connected by a rotating member 5 so that the lower sleeve 1 and the upper sleeve 2 can be flipped open and closed. The lower sleeve 1 and the upper sleeve 2 are each provided with a tooth socket 11 on the side away from each other, and the inner walls on both sides of each end of the tooth socket 11 are installed with root pressing spring plates 12. The two opposite root pressing spring plates 12 are arched toward each other to ensure that the teeth are pressed and fixed. The front inner wall of the middle part of the tooth socket 11 is installed with an incisor pressing block 13 for pressing the incisors.

[0022] In this embodiment, gaskets 3 are installed on the surfaces of the upper sleeve 2 and the lower sleeve 1 close to each other, so as to protect the surfaces of the lower sleeve 1 and the upper sleeve 2 and avoid wear.

[0023] Specifically, a limiting protrusion 4 is installed at the front end of the upper sleeve 2 and the lower sleeve 1 close to each other, which is used to limit the position between the lower sleeve 1 and the upper sleeve 2 to avoid discomfort to the tongue caused by too close fitting.

[0024] A threaded rod 61 is threadedly screwed on the outer wall of the tooth socket 11 between each root clamping spring piece 12 and the incisor clamping block 13. One end of the threaded rod 61 is located outside the tooth socket 11 and is provided with a handle 63. The outer wall of the handle 63 is provided with anti-slip grooves, which has a good fixing effect. The other end of the threaded rod 61 is located in the tooth socket 11 and is provided with a clamping plate 62. The surface of the clamping plate 62 is provided with a soft pad 621 for clamping and fixing the teeth.

[0025] A groove 14 is provided on the front inner wall of the middle part of the tooth socket 11, and the incisor pressing block 13 is slidably embedded in the groove 14 and connected to the bottom of the groove 14 through multiple springs 141. The spring 141 makes the incisor pressing block 13 fit against the incisor to ensure the fixation of the tooth pad during use.

[0026] The rotating member 5 includes an inner rotating shaft 51 and an outer rotating sleeve 52. The inner rotating shaft 51 is arranged at both ends of the lower sleeve 1, and the outer rotating sleeve 52 is arranged at both ends of the upper sleeve 2. The inner rotating shaft 51 is rotatably connected with the corresponding outer rotating sleeve 52 to ensure flexible rotation of the lower sleeve 1 and the upper sleeve 2.

[0027] When the dental pad of the utility model is used, in the preparation stage of electric shock therapy, the patient is required to open the mouth and place the lower sleeve 1 and the upper sleeve 2 of the dental pad between the upper and lower teeth respectively. Since the two ends of the lower sleeve and the upper sleeve are connected by the rotating member 5, the dental pad can be easily turned over and opened and closed to adapt to the oral morphology and tooth arrangement of different patients.

[0028] When the tooth pad is correctly placed, the root pressing spring piece 12 and the incisor pressing block 13 will fit the patient's teeth tightly. The root pressing spring piece 12 adopts an arc structure, which can elastically provide uniform and stable pressing force. The incisor pressing block 13 is designed as an outwardly protruding arc structure to better provide additional support.

[0029] During the treatment, when the current stimulates the patient, the patient's upper and lower jaws will bite tightly. At this time, the root pressing spring piece 12 and the incisor pressing block 13 work together to effectively reduce or avoid oral cavity or tongue damage caused by trismus.

[0030] In addition, the use of the gasket 3 increases the contact area between the dental pad and the patient's oral cavity, thereby improving the comfort of use. The gasket 3 made of silicone material is soft and has good elasticity, and can adapt to the oral conditions of different patients.

[0031] After the treatment, the patient can open the dental pad by simply flipping it over for easy removal. During the entire use process, the dental pad is always stably fixed in the patient's mouth, effectively preventing the dental pad from falling off due to patient activities or fear.
