Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a cold stimulation device for rehabilitating dysphagia. Background Art

[0002] Dysphagia is a common complication of many neurological diseases (such as stroke, traumatic brain injury, Parkinson's disease, etc.) and after head and neck tumor surgery, which seriously affects the patient's nutritional intake and quality of life, and may even cause life-threatening conditions such as aspiration pneumonia. Traditional rehabilitation treatment methods for dysphagia are diverse, but there are certain limitations. For example, oral motor training depends on the patient's active cooperation and the therapist's experience, and has poor effects on some patients with severe dysphagia; electrostimulation therapy may cause discomfort to patients, and the equipment is relatively complex and costly. Cold stimulation, as a sensory stimulation method, has the characteristics of simplicity, feasibility, economy and relatively high safety. Its principle is to stimulate the nerve endings in the oral cavity and pharynx through low temperature, enhance the sensitivity and contractility of muscles, so as to improve swallowing function; Existing cold stimulation methods are often relatively simple, such as using ice cubes, etc. The temperature is difficult to accurately control, and the stimulation site and intensity are also not easy to grasp. There is a lack of a standardized cold stimulation device specifically designed for the rehabilitation of dysphagia.

[0003] In view of the above problems, a cold stimulation device for rehabilitating dysphagia is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a cold stimulation device for rehabilitating dysphagia, which solves the problems in the background art that the existing cold stimulation method uses ice cubes, making it difficult to control the temperature and the stimulation site.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A cold stimulation device for rehabilitating dysphagia, comprising: a housing; a conduction rod detachably connected to one end of the housing; a stimulation head fixedly connected to the conduction rod; a cleaning mechanism located outside the conduction rod and adapted to the stimulation head; a refrigeration mechanism located inside the housing; the refrigeration mechanism includes a refrigeration sheet, a heat sink and a fan. The refrigeration sheet is detachably connected inside the housing, the refrigeration sheet is fixedly connected to the conduction rod, the heat sink is fixedly connected to the back of the refrigeration sheet inside the housing, and the fan is fixedly connected to the rear of the heat sink inside the housing.

[0006] As a further description of the above technical solution: The cleaning mechanism includes a cleaning push rod, an extension rod, a cleaning plate, a cleaning spring and a cleaning sponge. The cleaning push rod is embedded and connected to the outer wall of the housing. The extension rod is slidably connected inside the cleaning push rod. One end of the extension rod away from the cleaning push rod is fixedly connected to the cleaning plate. Cleaning holes are formed on the surface of the cleaning plate, and the cleaning sponge is detachably connected to the inside of the cleaning holes through the cleaning spring.

[0007] As a further description of the above technical solution: an operation panel is embedded in the outer side wall of the housing.

[0008] As a further description of the above technical solution: a power supply is fixedly connected inside the housing, and the power supply is electrically connected to the operation panel and the fan.

[0009] As a further description of the above technical solution: a rubber pad is fixedly connected to the outer side wall of the housing.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A cold stimulation device for rehabilitating swallowing disorders provided by the present invention cools the conduction rod and the stimulation head through a refrigeration sheet to make it reach the required stimulation temperature, and then inserts the conduction rod and the stimulation head into the patient's oral cavity to stimulate parts such as the root of the tongue, the edge of the tongue, the soft palate, the hard palate, and the posterior pharyngeal wall, enhancing the sensitivity and contractility of the muscles, thereby improving the swallowing function. Moreover, the heat sink can dissipate the transferred heat, improving the heat dissipation efficiency, and the fan increases the air flow to provide a stable low-temperature environment, thus achieving a better stimulation effect.

[0011] 2. A cold stimulation device for rehabilitating swallowing disorders provided by the present invention sprays disinfectant on the stimulation head after it is used through a cleaning mechanism, and then moves the position of the cleaning sponge through the extension rod and the cleaning push rod to contact the stimulation head through the cleaning spring to clean it and prevent cross-infection. Moreover, the cleaning sponge is disposable and easy to disassemble, increasing the cleaning efficiency in the later stage. Description of the Drawings

The surface of the stimulation head 3 is specially treated to have a certain anti-slip property, ensuring that a stable stimulation force can be applied when contacting the oral mucosa and it is not easy to slide. A pressure sensor is provided on the stimulation head 3, which can measure the magnitude of the applied pressure and feedback the pressure data to the operation panel 6 of the device.

The operation panel 6 also has a feedback record setting, which can automatically store relevant parameters of each treatment, including treatment time, temperature setting, stimulation site, pressure value, and patient's reaction, etc.
