Description

Technical Field

[0001] This invention relates to the field of stroke recovery treatment equipment technology, and in particular to a fixed stroke acid stimulation recovery device. Background Technology

[0002] Stroke, commonly known as apoplexy, is divided into ischemic stroke and hemorrhagic stroke. It is a disease caused by various factors that damage cerebral blood vessels, resulting in focal or systemic brain tissue damage. The most common complication of stroke is dysphagia, which refers to difficulty in eating or drinking, choking, and even malnutrition, aspiration pneumonia, or suffocation due to damage to the jaw, lips, tongue, soft palate, pharynx, esophageal sphincter, or esophagus. Currently, treatments for dysphagia include traditional acupuncture, ice stimulation, and acid stimulation. Traditional acupuncture involves directly stimulating the patient's throat with needles to promote swallowing, but it requires strict operation, is prone to infection, and has a relatively narrow scope of application. Ice stimulation involves inserting frozen cotton swabs or ice cubes directly into the patient's mouth, but sterilization of equipment is difficult, posing a risk of aspiration. Furthermore, melting ice can produce liquid water that may cause choking. Acid stimulation involves applying a highly acidic substance to cotton swabs in addition to traditional therapies, but this method is difficult to control in terms of dosage.

[0003] Xu Cailing, Duan Peibei, et al., in their study "Observation on the Effect of Vitamin C Acid Stimulation on Improving Dysphagia in Stroke Patients" [J] (China Continuing Medical Education, 2017, 9(25): 96-97), disclosed a method of using vitamin C to stimulate the tongue of patients for the recovery treatment of dysphagia. This method involves applying acid powder to the center of the patient's tongue with a cotton swab for acid stimulation, followed by massage to relax the tongue muscles and achieve better recovery results. While the method disclosed in this literature is feasible, it requires timed and fixed-point acid stimulation or massage, resulting in low treatment efficiency; furthermore, the lack of specialized equipment for treating the patient's tongue makes the treatment inconvenient.

[0004] A fixed-type acid stimulation recovery device for stroke is disclosed in Chinese invention patent with authorization announcement number CN110947074B. The device uses a micro air pump to blow vitamin C acid powder into the oral cavity for acid stimulation treatment. Although it can achieve dosage control of vitamin C acid powder, the device must be used to blow the acid powder in every time acid stimulation is performed, which is inefficient. In addition, the device does not have a tongue massage function. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fixed acid stimulation recovery device for stroke, which solves the problems of low treatment efficiency and inability to massage and relax the patient's tongue in existing acid stimulation devices.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A fixed stroke acid stimulation recovery device includes a device housing, an acid stimulation mechanism, a tongue massage mechanism, and a tooth fixation mechanism; the tooth fixation mechanism is located on both sides of the device housing; the acid stimulation mechanism is located at the top of the device housing, and the acid stimulation mechanism releases acid powder to stimulate the tongue; the tongue massage mechanism is located at the bottom of the device housing.

[0008] In this treatment, the entire device is fixed inside the oral cavity using a dental fixation mechanism. After fixation, the device shell is positioned directly above the tongue. The acid stimulation device inside releases acid powder to stimulate the patient's tongue, activating the tongue muscles. Following activation, a tongue massage mechanism massages the tongue to relax the muscles. The combined action of acid stimulation and massage therapy achieves better treatment results. During treatment, the entire device is fixed to the teeth, eliminating the need for the physician to hold the instrument, making it convenient to use. Combining acid stimulation and massage functions, it offers high treatment efficiency and reduces workload.

[0009] Furthermore, the acid stimulation mechanism includes an acid powder hopper, which is fixed inside the device housing; the acid powder hopper contains acid powder; the discharge port of the acid powder hopper is located through the bottom of the device housing; a rotating discharge disc is rotatably connected inside the discharge port, and the rotating discharge disc is driven by a discharge motor; an acid powder receiving cavity is opened on the side wall of the rotating discharge disc; the discharge motor drives the rotating discharge disc to rotate, and the rotating discharge disc sends the acid powder out from the discharge port through the acid powder receiving cavity.

[0010] In this design, acid powder enters the acid powder receiving cavity of a rotating dispensing disc. The dispensing motor drives the rotating dispensing disc to rotate, delivering the acid powder inside the receiving cavity to the patient's tongue. The amount of acid powder delivered by the rotating dispensing disc each time is the amount that the receiving cavity can hold. The dosage of acid powder released can be controlled by the number of rotations of the dispensing disc, making dosage control convenient. When periodic acid stimulation is required, the dispensing motor drives the rotating dispensing disc to release acid powder at regular intervals, enabling automatic recovery treatment in groups and sessions.

[0011] Furthermore, the acid powder hopper is equipped with a pressing block; a loading door is hinged to the top of the device housing; the pressing block is elastically connected to the loading door via a spring.

[0012] In this design, a spring-connected pressing block forces the acid powder into the acid powder receiving cavity, preventing the acid powder from failing to enter the cavity under its own weight and thus accumulating at the discharge port, thereby improving the smoothness of acid powder release.

[0013] Furthermore, the tongue massage mechanism includes a massage disc, which is movably connected inside the device housing via bearings; a through hole is opened at the center of the massage disc, through which the outlet of the acid powder hopper passes; a toothed groove is provided on the top of the massage disc, and the massage disc is connected to the gear on the output shaft of the rotary motor via the toothed groove; the rotary motor is fixed inside the device housing.

[0014] The massage disc has several sets of massage components arranged in a circular array.

[0015] The massage assembly includes a first gear and a second gear, which are meshed together. The inner wall of the device housing is provided with an annular tooth groove, and the first gear is meshed with the annular tooth groove. Both the first gear and the second gear are movably connected to the massage disc via a rotating shaft. The side of the first gear and the second gear away from the massage disc is connected to the massage ball assembly via an eccentric shaft.

[0016] A rotary motor drives the massage disc to rotate, which in turn drives the first gear and the second gear to rotate circumferentially around the center of the massage disc. During the circumferential rotation, due to the meshing of the first gear and the annular tooth groove, the first gear rotates on its own axis, which in turn drives the massage ball assembly to rotate circumferentially around the center of the first gear.

[0017] In this design, when the rotary motor drives the massage disc to rotate, the massage ball assembly not only follows the massage disc in a wide-range circumferential motion around its center, but also, driven by the rotation of the first gear, performs a small-range circumferential motion around the center of the first gear. This motion method can massage and relax the overall muscles of the tongue, while also massaging and relaxing local muscles, achieving a massage and relaxation effect from all directions and angles. The massage effect is good, and the tongue muscles are thoroughly and comprehensively relaxed.

[0018] Furthermore, the massage ball assembly includes a ball shell, which is fixedly connected to the bottom of the eccentric shaft; a spring is provided inside the ball shell, and the massage ball is connected to the bottom of the spring.

[0019] In this solution, a massage ball is connected by a spring. During the massage, the spring can make appropriate expansion and contraction adjustments according to the contact pressure between the massage ball and the tongue, making the massage process more comfortable and improving the patient's experience.

[0020] Furthermore, an installation plate is provided inside the device housing; the top of the installation plate receives the acid powder hopper, and a hole is opened in the center of the installation plate to form a discharge port;

[0021] Both the discharge motor and the rotary motor are fixed on the mounting plate. The mounting plate has a slotted hole, through which the gear on the output shaft of the rotary motor passes and is connected to the massage disc.

[0022] The bottom of the mounting plate forms an annular inner cavity, and a sealing membrane assembly is provided at the bottom of the annular inner cavity.

[0023] In this design, the device housing and mounting plate are integrally formed, and a discharge hole is formed in the middle of the mounting plate. The design is ingenious and the structure is simple. An annular inner cavity is formed at the bottom of the mounting plate for installing the tongue massage mechanism.

[0024] Furthermore, the sealing membrane assembly includes an annular sealing plate, which is embedded in an annular inner cavity; an annular sealing membrane is provided at the bottom of the annular sealing plate, and a threaded outer ring and a threaded inner ring are provided at the bottom of the annular sealing membrane. The threaded outer ring is threadedly connected to the outer ring of the annular inner cavity, and the threaded inner ring is threadedly connected to the inner ring of the annular inner cavity; the threaded outer ring and the threaded inner ring press and fix the annular sealing membrane on the annular sealing plate.

[0025] In this design, an annular sealing membrane is wrapped around the bottom of the annular inner cavity to seal the tongue massage mechanism inside, preventing saliva from the patient's mouth from entering the device. The annular sealing membrane is fixed to the annular sealing plate by a threaded outer ring and a threaded inner ring, which is convenient to fix. When the annular sealing membrane needs to be replaced, the threaded outer ring and the threaded inner ring can be unscrewed to replace the annular sealing membrane, which is convenient to replace.

[0026] Furthermore, the dental fixation mechanism includes two sets of portal-shaped braces, which are connected to both sides of the device housing via rods.

[0027] In this treatment, two sets of portal braces are fitted onto the teeth on both sides of the patient's tongue to fix the device inside the patient's mouth. The symmetrical design of the two sets of portal braces ensures that the device housing is located in the center of the tongue and also prevents lateral displacement during massage.

[0028] Furthermore, each set of gate-type clamps includes three clamp units, which are arranged in an arc shape; each clamp unit is rotatably connected to a rod.

[0029] In this design, the three clamp units are arranged in an arc shape according to the tooth arrangement path, and each clamp unit is rotatably connected to the rod. When fixed to the teeth, the angle can be flexibly adjusted to better correspond to the tooth position.

[0030] Furthermore, the annular sealing film is a medical-grade polyethylene film.

[0031] The beneficial effects of this invention are:

[0032] The acid stimulation recovery device provided by this invention includes an acid stimulation mechanism and a tongue massage mechanism. During treatment, the acid stimulation mechanism first stimulates the tongue to activate the taste buds and enhance the swallowing reflex. After stimulation, the tongue massage mechanism massages the tongue muscles to relax them and increase tongue flexibility. The acid stimulation mechanism releases acid powder through a rotating dispensing disc, facilitating dosage control. The tongue massage mechanism uses a rotary motor to drive a massage disc, which in turn causes the massage ball assembly to rotate over a wide range of circumferential directions. Simultaneously, a first gear drives the massage ball assembly to rotate over a smaller range of circumferential directions, achieving comprehensive massage and relaxation of the tongue. When using this device for treatment, the duration of acid stimulation and massage can be set according to the treatment cycle, allowing for automatic, periodic treatment with high efficiency.
