A handheld stroke recovery physical therapy cold stimulation device

technical field

The invention relates to the technical field of rehabilitation medical equipment, in particular to a swallowing disorder rehabilitation training device.

Background technique

Stroke is a group of diseases caused by the sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to vascular blockage. At present, the main method for clinical treatment of dysphagia is cold stimulation method, mainly using ice cotton swabs after freezing wet cotton swabs or simple ice cubes as the medium of cold stimulation. Ice cotton sticks have less ice content and short use time, and need to be replaced many times during rehabilitation treatment; ice cubes are easy to melt under normal body temperature, which is easy to cause patients to choke during treatment, which is more difficult for comatose patients. Great risk of suffocation.

Therefore, there is an urgent need to develop a refrigeration method that does not carry water into the oral cavity to perform cold stimulation on patients, in order to reduce the risk of patients receiving treatment and improve the convenience of treatment.
