Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a cold stimulation device for the rehabilitation treatment of swallowing disorders. Background Technology

[0002] Dysphagia is one of the most common complications of neurological diseases, which can lead to aspiration, aspiration pneumonia, malnutrition, and even death, severely impacting patients' quality of life and prognosis. Cold stimulation is currently one of the clinically recognized and commonly used rehabilitation treatments for dysphagia. Its principle is to activate the swallowing reflex pathway by cold stimulation of the oral and pharyngeal mucosa, enhancing the contraction strength and coordination of swallowing muscles, thereby improving swallowing function.

[0003] Currently, the most common clinical method of cold stimulation is the cotton ball soaked in cold water method: medical staff repeatedly wipe the patient's soft palate, tongue base, and pharynx with a cotton ball soaked in ice water. This method has many drawbacks: it requires repeated soaking in ice water and changing the cotton ball, which is cumbersome and has low treatment efficiency; the cotton ball is easily contaminated during repeated soaking, posing a risk of cross-infection. Therefore, there is a need to develop a cold stimulation device for the rehabilitation treatment of swallowing disorders. Summary of the Invention

The stimulation component is mounted on the support component and can be adjusted up and down in height along with the support component on the front side of the adjustment component to accommodate different users; The guide assembly is located at the bottom front side of the device body, and the chin support can slide back and forth along the guide assembly; the head support is adjustablely installed on the front side of the device body to support the patient's head and maintain the treatment position. The controller is installed on the main body of the device and is electrically connected to the cooling device and the adjustment component respectively; the fixing component is set on the main body of the device and is used to fix the main body of the device to the treatment support surface.

[0006] As a further improvement to the above solution, the stimulation component includes a cold water storage bottle, a delivery tube, a stimulation ball, and an discharge tube; The cold water storage bottle has a top opening and a downward-protruding cylindrical water outlet at the bottom center, with external threads on the outer wall of the water outlet. The delivery tube, stimulation ball, and discharge tube together form a disposable stimulation head, which is integrally molded from medical-grade silicone.

[0007] As a further improvement to the above solution, the top end of the delivery pipe is provided with a pipe joint that can be detachably connected to the outlet of the cold water storage bottle; a flow regulating valve is connected in series on the delivery pipe to regulate the flow rate of the cold water.

[0008] As a further improvement to the above solution, the adjustment component includes an adjustment slide rail, two support baffles, a transmission component, and a drive component; The adjusting slide rail is installed on the front side wall of the main body of the equipment; the two supporting baffles are respectively fixed at the upper and lower ends of the adjusting slide rail; the transmission component is vertically installed between the two supporting baffles; the driving component is connected to the transmission component, and its control end is electrically connected to the controller.

[0009] As a further improvement to the above solution, the transmission component is an adjusting screw, and the driving component is an adjusting motor; each of the supporting baffles is inlaid with a supporting bearing, and the adjusting screw is vertically installed in the inner ring of two supporting bearings; the adjusting motor is fixed on the lower supporting baffle, and its output shaft is coaxially connected to the bottom end of the adjusting screw through a coupling.

[0010] As a further improvement to the above solution, the support assembly includes a bottle neck bracket, a bottle body bracket, and an adjustment slider; The bottle body bracket is installed on top of the bottle mouth bracket; the adjusting slider is fixed at the rear end of the bottle mouth bracket; the front sides of the bottle mouth bracket and the bottle body bracket are respectively provided with bottle mouth slots and bottle body slots that match the cold water storage bottle.

[0011] As a further improvement to the above solution, an adjustment groove is provided on the rear side of the adjustment slider to slide with the adjustment slide rail; a positioning slider is fixed in the adjustment groove, and a screw hole is provided on the positioning slider to thread with the adjustment screw.

[0014] The beneficial effects of this invention are as follows: This invention adopts a closed-loop design of "centralized cooling + gravity circulation + real-time waste discharge". Cold water flows from the storage container into the stimulation ball by gravity and is discharged directly after use, so as to achieve continuous and uninterrupted cold stimulation. The stimulation ball with continuously circulating cold water is used for treatment, eliminating the need to repeatedly dip it in ice water and change cotton balls. Medical staff only need to install the disposable stimulation head on the cold water storage bottle and adjust the stimulation position and flow rate to carry out treatment, simplifying the operation process. This invention designs the delivery tube, stimulation ball, flow regulating valve, and discharge tube, which come into direct contact with the patient, as an integrated sterile disposable component. It can be quickly connected to a cold water storage bottle through a standard threaded interface and is discarded as a whole after use, avoiding the risk of cross-infection. The height of the stimulation component of this invention can be electrically adjusted by adjusting the component, the chin support can slide back and forth, and the head support can be adjusted in height and tilt angle to adapt to patients of different heights and body types; the silicone pad and buffer spring on the arc support plate can effectively buffer hard impacts and improve patient comfort.

In use, the U-shaped clamping plate 91 is clamped on the edge of the treatment table, and then the anti-slip knob is turned clockwise to move the fixing screw 93 upward until the rubber anti-slip pad is tightly pressed against the bottom surface of the table, thus firmly fixing the device on the table. The method of using this invention is as follows: Place the device on the edge of the treatment table, secure the two U-shaped clips 91 to the edge of the table, and turn the anti-slip knob to fix the device firmly. Turn on the power, turn on the touch screen PLC controller 8, set the cooling temperature of the semiconductor refrigeration unit to 2℃, and wait for the cold water temperature to drop to the set temperature. Unpack the sterile packaging of the disposable irritation head, screw the tube connector 45 onto the outlet of the cold water storage bottle 41, then place the cold water storage bottle 41 into the bottle mouth slot 34 and bottle body slot 35 of the support component 3, pass the bottom end of the discharge tube 44 through the tube slot 53, place a trash can below, and add an appropriate amount of cold water to the cold water storage bottle 41. Instruct the patient to sit upright and place their chin on the curved support plate 64. Slide the chin support 6 back and forth to a comfortable position. Adjust the first damping knob 75 and the second damping knob so that the curved plate 71 fits against the patient's forehead and supports the patient's head. The height of the support component 3 can be adjusted by the touch screen PLC controller 8 so that the stimulation ball 43 is aimed at the patient's soft palate or the base of the tongue. Open the flow regulating valve 46, adjust the cold water flow rate to a suitable level, and begin the cold stimulation therapy; After treatment, close the flow regulating valve 46, remove and discard the disposable stimulation head; turn off the power to the equipment and tidy up the equipment.
