[0002] Dysphagia refers to a group of clinical syndromes in which various symptoms appear due to damage to one or more stages of swallowing caused by swallowing-related nerve damage or swallowing organ damage. Dysphagia can be caused by various diseases such as stroke, brain trauma, cerebral palsy, dementia, Parkinson's disease, etc. Electrical stimulation technology is a relatively effective way to treat dysphagia. However, the functions of the treatment equipment in the related technology are relatively simple, usually only have treatment functions, but not observation and diagnosis functions. It is impossible to observe the movement of the tissues in the pharyngeal cavity when the patient swallows during the treatment process. Therefore, it is impossible to diagnose and evaluate the patient's dysphagia recovery during the treatment process. Therefore, the dysphagia diagnosis and treatment equipment in the related technology has a single function, cannot take into account the treatment and diagnosis of dysphagia, and the treatment effect is poor.

[0009] The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0010] An embodiment of the utility model provides a device for diagnosing and treating dysphagia. Figure 1 Schematic diagram of a swallowing disorder diagnosis and treatment device provided by an embodiment of the utility model. Figure 1 The dysphagia diagnosis and treatment device comprises: a host computer 10, a camera diagnosis device 20 and an electrical stimulation treatment device 30. The camera diagnosis device 20 is connected to the host computer 10, and the electrical stimulation treatment device 30 is connected to the host computer 10.

[0011] Among them, the electrical stimulation therapy device 30 includes: an electrical signal generating module 31 and an electrical stimulation applying module 32; the electrical signal generating module 31 is connected to the host computer 10 and the electrical stimulation applying module 32 respectively; the electrical stimulation applying module 32 is placed in the patient's pharyngeal cavity, and is configured to apply electrical stimulation to the patient's pharyngeal cavity according to the electrical signal generated by the electrical signal generating module 31.

[0012] The electrical stimulation therapy device 30 can electrically stimulate the muscles and other tissues in the patient's pharyngeal cavity, such as the pharyngeal constrictor muscles. Specifically, the electrical signal generation module 31 can generate an electrical signal according to the instructions issued by the host computer 10 or according to a separately accessed control instruction (such as an instruction directly issued by a doctor). The electrical signal can be, for example, a pulse signal. The electrical stimulation application module 32 can include a patch electrode or a stimulation electrode of other structures to apply electrical stimulation to the patient's pharyngeal mucosa based on the above-mentioned electrical signal. Exemplarily, the electrical stimulation therapy device 30 can exert its effect by delivering electrical pulses to the pharyngeal mucosa through a catheter electrode suspended on the surface of the pharynx through intrapharyngeal electrical stimulation (PES). In one embodiment, the electrical stimulation treatment device 30 activates the sensory nerves (and possibly the afferent motor nerves) in the mucosa through PES. These sensory nerves include the facial nerve, glossopharyngeal nerve, vagus nerve, and cranial nerves. The information (such as warmth, electrical stimulation, and burning sensation) stimulated by PES in the pharyngeal mucosa will be transmitted to the solitary nucleus in the brainstem and the higher-level swallowing center - the cerebral cortex and subcortex, and the brainstem will process the incoming information. The solitary nucleus innervated by the afferent nerves is closely related to the peripheral nerve efferent network, and thus connects the sensory input and coordinated motor output at the brainstem level. Through these complex interconnections, PES affects the output of the swallowing cortex motor signal to achieve the effect of dysphagia treatment.

[0013] The video diagnostic device 20 can be used to observe the tissues in the patient's pharyngeal cavity in real time. Exemplarily, the video diagnostic device 20 can be an electronic endoscope or an electronic laryngoscope, which includes a lens portion that extends into the patient's pharyngeal cavity. During treatment, the lens portion of the video diagnostic device 20 and the electrical stimulation application module 32 can be placed into the patient's pharyngeal cavity together. In this way, on the one hand, the reaction of the patient's pharyngeal cavity tissue to electrical stimulation can be obtained in a timely and intuitive manner before and after the electrical stimulation treatment, as well as during the electrical stimulation treatment; the imaging diagnosis of the patient's pharyngeal cavity through real-time video is more intuitive and accurate than the diagnostic method based on the acoustic signal and / or pressure signal in the patient's pharyngeal cavity. Second, the insertion depth and position of the electrical stimulation application module 32 can be intuitively obtained based on the image, so that the electrical stimulation application module 32 can electrically stimulate the tissues in the patient's pharyngeal cavity at the correct position to ensure the treatment effect.

[0014] The host computer 10 can be configured to collect tissue image data, such as pictures or video data, obtained by the camera diagnostic device 20, and judge the degree of the patient's dysphagia, the immediate response to electrical stimulation, and the state difference before and after electrical stimulation based on the image data, so as to judge the degree of recovery after electrical stimulation treatment. In addition, the host computer 10 can process the image data and display it intuitively, and can also extract effective information from the image data for display, which is helpful for doctors to judge the state of the patient's pharyngeal cavity. The host computer 10 can also display the electrical stimulation waveform applied by the electrical stimulation treatment device 30. The host computer 10 can also be configured to control the working state of the electrical signal generation module 31, so as to achieve control of the electrical stimulation treatment process. Exemplarily, an automatic diagnosis and treatment program or software can be set in the host computer 10. According to the above-mentioned state information in the pharyngeal cavity, the host computer 10 can automatically adjust the treatment plan within a certain range, such as adjusting the duration and / or intensity of electrical stimulation, so as to continuously adjust the treatment plan as the treatment progresses, so as to achieve better treatment effects. Alternatively, the instruction level issued by the medical staff is higher than the instruction level automatically generated by the host computer 10. The medical staff can formulate different treatment plans according to the characteristics of the lesions of different patients based on the above-mentioned intra-pharyngeal state information processed by the host computer 10, and continuously adjust the treatment plan as the treatment progresses. Then, the control instructions are issued through the host computer 10 or other human-computer interaction devices to continuously correct the electrical stimulation applied by the electrical stimulation treatment device 30 to achieve better treatment effects.

[0015] The swallowing disorder diagnosis and treatment device provided by the first embodiment of the utility model integrates a camera diagnosis device 20, an electrical stimulation treatment device 30 and a host computer 10. The camera diagnosis device 20 can be used to collect real-time images of the patient's pharyngeal cavity state, so as to intuitively and simply judge the patient's swallowing state; the electrical stimulation treatment device 30 can be used to electrically stimulate the tissue in the patient's pharyngeal cavity to achieve the swallowing disorder treatment effect; the host computer 10 can timely adjust the working state of the electrical signal generation module 31 according to the image data collected by the camera diagnosis device 20, thereby adjusting the electrical stimulation applied by the electrical stimulation application module 32 to the patient's pharyngeal cavity, so that the treatment process is more adapted to the change process of the patient's pharyngeal cavity state, and the intensity and duration of the electrical stimulation can be adjusted in combination with the patient's response to the electrical stimulation. In summary, the diagnosis and treatment process of the swallowing disorder diagnosis and treatment device provided by the first embodiment of the utility model is intuitive and visual, so that the intubation depth is accurate, and it can directly observe whether the patient has adverse reactions, the immediate response of the electrical stimulation, and the effect comparison before and after the electrical stimulation, which is conducive to achieving better treatment effects. Compared with the related art, an embodiment of the present invention can take into account both the treatment and diagnosis of dysphagia, thereby improving the reliability of diagnosis and the treatment effect.
