Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of catheter, concretely is pharynx electric stimulation catheter. BACKGROUND

[0002] The patient's swallowing and speech disorder is caused by nerve injury, muscle injury, radiation injury and the like, therefore, how to research and design a swallowing disorder training device is a problem that we need to solve at present, brain stroke, brain trauma, head and neck tumor radiotherapy and many other reasons can cause different degrees of swallowing disorder, the main performance is the sensation and movement disorder of oropharynx and throat, which seriously affects the patient's eating and speech function, swallowing is the result of a series of complex and highly coordinated muscle movements, the precise coordination of neuromuscular makes the oral cavity, pharynx and esophagus pipeline and valve contract and open in turn, which produces a pressure gradient that can push the bolus from the oral cavity to the esophagus in order, swallowing disorder can cause muscle strength of lips, tongue and pharynx to decrease and atrophy, resulting in the pressure gradient of bolus pushing being destroyed and the transport disorder, food residue or aspiration;

[0003] Pharyngeal muscle weakness is a common clinical manifestation of swallowing disorder, mainly manifested as weakness and relaxation of pharyngeal muscles, which causes pharyngeal residue, nasal regurgitation, aspiration and other symptoms during eating, and is a more difficult problem in the swallowing rehabilitation process, in order to improve the patient's dysfunction, the oropharyngeal part needs to be stimulated, so that the nervous system, transmission system and control system can form a unified whole again under repeated stimulation, and the purpose of recovery is achieved;

[0004] The treatment method for patients with pharyngeal muscle weakness includes drug treatment, physical therapy and surgical treatment, cold, heat, pressure and other signals are used as stimulation signals, although they can play a certain therapeutic role, but in the actual use process, there are problems such as weak persistence, frequent replacement and difficulty in maintaining a relatively stable state of stimulation signals during use, resulting in unsatisfactory treatment effect, peripheral electric stimulation is one of the effective physical treatment methods, by applying different frequency and intensity of electric stimulation to pharyngeal muscle group, it can help pharyngeal muscle to exercise properly, so as to prevent muscle atrophy and promote rehabilitation, low frequency electric stimulation technology has been widely used in the fields of rehabilitation medicine, sports training and beauty, in the treatment of pharyngeal muscle weakness, because it is a cavity muscle, surface electric stimulation cannot achieve accurate and effective stimulation, therefore, it is particularly important to invent a catheter for intracavity electric stimulation.

[0005] The mature technology for pharyngeal constrictor muscle electrical stimulation at present includes low-frequency electrical stimulation, induced electrical therapy, electroacupuncture, etc. for peripheral stimulation, transcranial direct current stimulation for central action. The commonly used peripheral electrical stimulation instrument for dysphagia in clinical practice is low-frequency pulse or induced electrical therapy instrument. The transcranial direct current stimulation for central electrical stimulation is all surface stimulation, which cannot directly stimulate the pharynx. The electroacupuncture is invasive and has a certain depth, but also cannot enter the pharynx, especially the hypopharynx. The pharyngeal cavity electrical stimulation technology has been developed abroad, but it is still relatively rare in China. The main reasons include the following aspects: first, there is a lack of sufficient clinical research evidence to support its therapeutic effect. Although the technology has achieved certain research results abroad, large-scale clinical trials and evaluation have not been conducted in China. Second, the equipment of the pharyngeal cavity electrical stimulation technology is relatively expensive, which may limit its promotion and application in clinical practice. Meanwhile, the intracavity electrode cannot be used by one person, and needs to be sterilized for repeated use, which also increases the complexity and cost of use. In view of the shortcomings of the prior art, the utility model aims to provide a pharyngeal electrical stimulation catheter. Utility model content
