The invention discloses a multi-stimulation device for dysphagia rehabilitation training, and relates to the field of rehabilitation training instruments. According to the multi-stimulation device for dysphagia rehabilitation training, a user can load stimulation liquid with different cold and hot temperatures and various tastes in the liquid containing tank, the variety of the stimulation liquid connected into the guide pipe is changed by rotating the rotary drum, and therefore the stimulation liquid with different temperatures and the stimulation liquid with different tastes can be replaced; a heating wire and a semiconductor chilling plate are additionally arranged on the outer wall of the liquid containing tank, so that the liquid temperature is adjusted bidirectionally, and accurate cold and hot temperature control is achieved; a user can press the pumping assembly to pump the stimulation liquid into the bite pad through the guide pipe and the rotary drum, the stimulation liquid is sprayed out from the end of the massage block, a patient can bite the bite pad to receive alternate stimulation treatment of the stimulation liquid, the stimulation liquid with different tastes or different temperatures is rapidly alternated, a TRPV1 temperature-sensitive ion channel and a P2X3 purine receptor can be effectively activated, and the treatment effect is good. Signal transduction of a swallowing reflex arc is enhanced through double paths, and precise rehabilitation is achieved.

Methods and systems for monitoring, preventing and / or treating upper airway disorders such as apnea, dysphagia, reflux and / or snoring are described. The methods and systems monitor the upper airway disorders by processing one or more neural signals obtained from one or more upper airway afferents. Upper airway disorders are prevented and / or treated by delivering one or more stimulations to one or more reflex-related afferents, efferents, muscles, and sensory receptors to manipulate the threshold and / or trigger an upper airway reflex including, but not limited to a swallow reflex and / or a negative-pressure reflex.

The invention discloses a sucking screw for oral and labial muscle training, and particularly relates to the field of oral and labial muscle training.The sucking screw comprises a shell, the shell is in a screw shell shape, a smooth pipeline is arranged in the shell, and the smooth pipeline is coiled in a screw shell shape; the piston is arranged in the smooth pipeline, and the diameter of the piston is the same as that of the inner wall of the smooth pipeline; and the top cover is installed at the top end of the shell, a connecting assembly is arranged at the bottom end of the top cover, and the bottom end of the top cover is detachably connected with the top end of the shell. The device can actively cooperate with a treated patient, the suction ability training is dominated, the blowing function is assisted, the lip closing function and the tongue muscle activity ability can be directly trained through the suction function training, salivary secretion can be promoted through suction, swallowing reflex can be induced, and the swallowing function is indirectly trained; through the training of the blowing function, the strength and endurance of cheek muscles can be exercised.

To provide a dysphagia diet determination device capable of accurately determining the selection of a meal suitable for the individual swallowing state of a subject.SOLUTION: The swallowing food determination device is a swallowing food determination device for determining a swallowing food layer suitable for a subject on the basis of a meal situation of the subject from among swallowing food layers obtained by classifying the swallowing food into a plurality of layers on the basis of a degree of eating and swallowing, the swallowing food determination device including: an apnea measurement means for measuring an apnea situation in which breathing of the subject becomes apnea during a meal on the basis of the meal situation; a reflex measurement means for measuring a reflex situation of a swallowing reflex generated in a larynx of the subject during a meal on the basis of the meal situation; and a determination means for determining the swallowing food layer suitable for the subject on the basis of the apnea situation and the reflex situation.SELECTED DRAWING: Figure 1

The invention discloses a mistaken-suction-preventing feeding auxiliary device for a patient with dysphagia. The mistaken-suction-preventing feeding auxiliary device comprises a food storage box and a feeding device. The food storage box is provided with a containing cavity used for containing dysphagia food. The feeding device comprises a metering cylinder, a piston and a feeding pipe, the metering cylinder is provided with a temporary storage cavity, and the metering cylinder is connected with the food storage box through a feeding pipe; the piston is movably sleeved in the metering cylinder; one end of the feeding pipe is connected with the metering cylinder, and a food outlet is formed in the other end of the feeding pipe. The metering cylinder is matched with the piston, so that the volume of food entering the temporary storage cavity each time can be quantified, and it is ensured that each fed food ball has the stable and consistent volume. When the piston moves forwards, the speed of extruding food can be controlled by adjusting the moving speed of the piston, so that food balls enter the feeding pipe at a slow and uniform flow speed, and the phenomenon that the food balls directly flow into the pharyngeal cavity due to too fast delivery is prevented. The feeding pipe enables the food balls to cross a sensitive area in the front middle of the oral cavity and a complex pushing process and directly reach a starting area of swallowing reflex.

This invention discloses a variable-frequency ultrasonic rehabilitation trainer for dysphagia following stroke, comprising an ultrasonic system, an insulating shell, a power supply, a base, and gaskets. The ultrasonic system consists of an ultrasonic drive circuit board, a sandwich-type piezoelectric transducer, and an ultrasonic amplitude transformer. Impedance matching achieves system coupling. The ultrasonic power supply, connected to a microcontroller signal control module on a separate circuit board, provides impedance matching and frequency tracking functions. Integrated chips, multivibrators, and low-pass filters control the intensity of the ultrasonic waves, thus changing the power of the ultrasonic rehabilitation trainer. The ultrasonic amplitude transformer is an exponentially transitional, small-end symmetrical type, exhibiting longitudinal or torsional vibration characteristics and advantages in length and shape. It is also equipped with medical-grade silicone sleeves of various shapes. Patients with dysphagia can use the trainer to stimulate the palatal arch, soft palate, tongue base, and posterior pharyngeal wall, enhancing muscle contraction and inducing the swallowing reflex.

The present application relates to the technical field of intelligent medical health monitoring, in particular to a new-born low blood sugar early warning method in mother-infant room based on multi-parameter fusion, comprising the following steps: analyzing the heat production process and oxygen consumption quantitative basal metabolic equivalent, evaluating the cold exposure and high-frequency movement energy consumption stress increment data, tracking the swallowing reflex to evaluate sugar intake combined with increment calculation energy gap to generate deficiency index, monitoring microcirculation compensation and muscle tremor amplitude to generate early warning intervention instruction set.
