Description

Technical Field

[0001] The invention relates to a pneumatic temporomandibular joint movable device. Background Art

[0002] Temporomandibular joint dysfunction is one of the common diseases in clinical practice. Temporomandibular joint dysfunction syndrome refers to a series of symptoms such as pain, snapping, muscle soreness, fatigue, limited mouth opening, and temporomandibular joint dysfunction in the temporomandibular joint area. Some cases have repeated attacks, prolonged and long-lasting symptoms, which seriously affect the masticatory muscles and language functions. From the perspective of modern medicine, the cause of this disease is relatively complicated and is still unclear. It is currently believed that it is related to factors such as emotional instability, physical weakness, disordered tooth occlusion, and trauma. These factors affect the normal structure of the mandibular joint or cause disorders in the coordinated movement of muscles and ligaments attached to the joint structure.

[0003] Existing treatment methods include: light, electricity, acupuncture, injection, physical therapy and other methods.

[0004] For example: ultra-laser therapy device, temporomandibular arthroscopy, acupuncture combined with ultra-short wave therapy, ultra-laser irradiation combined with local injection therapy of the temporomandibular joint, bloodletting and heated needle therapy, etc., each has its advantages and disadvantages and is suitable for different groups of people.

[0005] Another form of physical therapy mainly relies on traction devices and therapist's manual pressure. It is convenient and safe, has a wide range of applications, low medical costs, high cure rate, and high patient acceptance. Patent No. ZL201420629753.4 discloses a temporomandibular joint opening exerciser. Patent Nos. WO2012024828A1, AU2013334877A1, CA2663354A1, KR20120033385A and RU2440063C1 also disclose similar temporomandibular joint movable devices. However, currently, when clinical patients have stiff jaw joints and limited range of motion, the physical traction device treatment mode is a single vertical mouth slowly open, forcing the temporomandibular joint to slowly rotate for a period of time, and then return to the original state, and the treatment cycle is repeated for several, several days, or several weeks. However, when treating the temporomandibular joint, the doctor cannot intuitively obtain the change information of the temporomandibular joint movable device and the force information applied to the patient, which may lead to an increase in the patient's pain or an insignificant treatment effect. That is, the doctor needs to manually adjust the mouth opening distance and is unable to provide feedback for cooperative diagnosis. Therefore, there are defects such as insufficient comfort and lack of compliance in current clinical applications. Summary of the invention

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific implementation methods thereof are described in detail below in conjunction with the accompanying drawings:

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The best embodiment of the present invention is a pneumatic temporomandibular joint movable device, comprising a housing 14, a display screen 13, an opening and closing mechanism and a laser sensor 17. The housing 14 is in a trapezoidal shape, and the display screen 13 is embedded in the front surface of the housing 14; a semicircular groove 20 is provided at the front end of the bottom of the housing 14, and the opening and closing mechanism is provided in the semicircular groove 20; the opening and closing mechanism comprises a porous gas disk 10 and a polymer film sheet 15, the porous gas disk 10 is composed of a stainless steel tube, a plurality of air outlet holes opened on the tube wall of the stainless steel tube, and a polymer porous fiber 16 filled in the stainless steel tube, and the plurality of air outlet holes are evenly and densely distributed on the tube wall of the stainless steel tube; the polymer film sheet 15 is coated on the outside of the porous gas disk 10; the laser sensor 17 is provided on the front surface of the housing 14, and the laser sensor 17 is located above the display screen 13.

[0028] A battery 1, an air pump 2, a solenoid valve 18, an air pipe 9 and a pressure sensor 11 are arranged in the shell 14. The battery 1 supplies power to the air pump 2, and the air inlet of the air pipe 9 is connected to the porous air disk 10; the solenoid valve 18 adopts a three-position two-way solenoid valve, and has a solenoid valve air outlet 5 and a solenoid valve air inlet 7; the solenoid valve air inlet 7 is connected to the air outlet 3 of the air pump 2 through a connecting pipe 4; when the air pump 2 is working, the air is taken in by the air pump 2 through the air inlet 8 of the air pump, and the air is transported through the operation of the air pump 2, and then sent to the solenoid valve 18 through the connecting pipe 4 from the air outlet 3 of the air pump; when the solenoid valve 18 is energized, the solenoid valve air inlet 7 is connected to the air outlet 6 of the air pipe 9 to supply air to the porous air disk 10; when the solenoid valve 18 loses power, the solenoid valve air outlet 5 is directly connected to release air.

[0029] The main control board 12 is arranged on the back of the display screen 13; the air pump 2, the electromagnetic valve 18, the laser sensor 17 and the pressure sensor 11 are respectively connected to the main control board 12. The display screen 13 is provided with up and down buttons for adjusting the predetermined opening distance.

[0030] The pneumatic temporomandibular joint movable device of the present invention sets a predetermined opening distance by means of the up and down buttons. The main control board 12 sends a working signal to the air pump 2 and the solenoid valve 18 according to the predetermined opening distance. The air pump 2 delivers air to the solenoid valve 18 when in operation, and then supplies air to the porous air disk 10 through the air pipe 9. The polymer porous fibers 16 expand, thereby driving the height of the polymer film sheet 15 to increase. The laser sensor 17 measures the actual height of the polymer film sheet 18 in real time to obtain the actual opening distance, and feeds back the actual opening distance to the main control board 12. The pressure sensor 11 senses the air pressure value output by the air pump 2, and sends the air pressure value data to the main control board 12. The main control board 12 sends the actual opening distance and air pressure value data to the display screen 13 for display. Since the laser sensor 17 is arranged above the display screen 13, the influence of other devices on the information obtained by the laser sensor 17 can be avoided, so that the laser sensor 17 can obtain more accurate information.

[0031] The pneumatic temporomandibular joint movable device of the present invention can be activated by long pressing any point on the display screen 13 when the patient is very uncomfortable or needs to change the treatment method urgently. The upper and lower buttons on the display screen 13 are adjusted to the initial position respectively, and then the patient is asked to bite the polymer film sheet 15. At this time, if you want to open your mouth wider, you can adjust the upper button on the display screen 13 to set the mouth opening distance. The mouth opening distance between the temporomandibular joints can be up to about 45mm. The main control board 12 controls the air pump and the solenoid valve to deliver air to the porous air disk 10. The polymer porous fiber 16 expands and drives the height of the polymer film sheet 15 to increase, thereby adjusting the actual mouth opening distance. The mouth opening distance (unit MM) and force (unit N) information of the whole process are displayed in real time on the display screen 13. While easily opening the patient's stiff mouth, the doctor can record the mouth opening distance and torque change value during the stretching treatment process, and can understand the relevant information of the patient more specifically and provide treatment that is more in line with the actual situation.

[0032] During use of the pneumatic temporomandibular joint mobilization device of the present invention:

[0033] (1) Improve the original simple physical therapy and add sensing devices, such as mouth opening distance detection and force detection. Doctors can use the acquired sensing information to enable patients to receive treatment in a comfortable state, eliminate patients' tension and fear, improve the range of motion and flexibility of mouth opening in a painless treatment, and almost eliminate the range of motion rebound effect by creating permanent, non-traumatic tissue elongation and remodeling;

[0034] (2) The mouth-opening treatment is driven by an air pump to automatically help the temporomandibular joint head move downward and forward, thereby widening the gap between the temporomandibular joints and making it easier to open the mouth.

[0035] (3) In addition, by real-time monitoring and guiding patients to use the device, it can achieve safer and more effective improvement in mouth opening, while also reducing the workload of therapists and the therapists' full use of manual skills, which is suitable for the promotion and application of this technology.

[0036] In summary, the pneumatic temporomandibular joint mobilization device of the present invention realizes air pump-driven mouth opening treatment, has a compact appearance, is easy to carry, and patients can treat themselves at any time, which is safe and comfortable.
