The core of the utility model is to provide a swallow training appearance, professional treatment doctor only need contrast training patient's laryngeal muscle around the signal of telecommunication, alright know swallow training appearance to patient's improvement degree of swallowing the obstacle to professional treatment doctor's intensity of labour has been reduced.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a swallowing training instrument according to an embodiment of the present invention.
This swallowing training appearance includes:
the piezoresistive pressure sensor 1 is placed in the throat of a patient during swallowing detection of the patient, and is used for detecting the motion force of the throat muscle of the patient during swallowing of food of the patient and generating an electric signal for representing the motion force;
a throat muscle trainer 2 which is placed in the throat of a patient during swallowing training;
the controller 3 is respectively connected with the output end of the piezoresistive pressure sensor 1, the control end of the laryngeal muscle trainer 2 and the upper computer and is used for controlling the laryngeal muscle trainer 2 to train the laryngeal muscles of the patient after receiving the swallowing training instruction; when swallowing detection is carried out on a patient, the electric signal is uploaded to an upper computer to be displayed for a professional treating doctor to check.
Specifically, the swallowing training appearance of this application includes piezoresistive pressure sensor 1, laryngeal muscle training ware 2 and controller 3, and its theory of operation is:
first, this application can carry out the dysphagia degree to the patient of dysphagia and detect, considers that the motion dynamics of patient's throat muscle can embody patient's dysphagia degree, so this application can detect the motion dynamics of patient's throat muscle through placing pressure sensor in patient's throat position, and then acquires patient's dysphagia degree. The working principle of the pressure sensor is as follows: when a patient swallows food, the laryngeal muscles of the patient move, if the swallowing disorder of the patient is serious (namely the patient swallows the food difficultly), the movement force of the laryngeal muscles of the patient is small, and in this case, the pressure value sensed by the pressure sensor is small, and the generated electric signal is small; on the contrary, if the swallowing disorder of the patient is slight, the movement force of the laryngeal muscles of the patient is large, in this case, the pressure value sensed by the pressure sensor is large, and the generated electric signal is also large. Therefore, the motion force of the laryngeal muscles of the patient can be detected based on the working principle of the pressure sensor, and the swallowing disorder degree of the patient is acquired.
Based on this, for the convenience of professional treatment doctor knows patient's swallowing disorder degree, the signal of telecommunication of the dynamics of motion of the characterization patient laryngeal muscle that pressure sensor of this application will generate sends controller 3, then upload the signal of telecommunication to the host computer by controller 3 and show, professional treatment doctor alright with the size of seeing the signal of telecommunication from the host computer to know the current swallowing disorder degree of patient, and then decide whether the patient needs to swallow the training next based on the current swallowing disorder degree of patient.
When a patient needs swallowing training and agrees with the swallowing training, the laryngeal muscle trainer 2 can be placed at the throat position of the patient, and a swallowing training instruction is sent to the controller 3 (specifically, the controller 3 is connected with a control key, the long key is controlled to send the swallowing training instruction to the controller 3 through a long key representative so as to open the laryngeal muscle trainer 2, the control key is controlled to send a swallowing training ending instruction to the controller 3 through a long key representative so as to close the laryngeal muscle trainer 2, and the control key can be controlled by a professional treating doctor), and then the controller 3 controls the laryngeal muscle trainer 2 to train the laryngeal muscle of the patient after receiving the swallowing training instruction.
Then, treat that the patient swallows after the training finishes, pressure sensor can be placed at patient's throat position once more in this application and detect the motion dynamics of patient's laryngeal muscle, and pressure sensor sends the signal of telecommunication of the motion dynamics of the characterization patient's laryngeal muscle that generates to controller 3 equally, then is displayed to the host computer on uploading the signal of telecommunication by controller 3, and the size of signal of telecommunication can be followed from the host computer again to professional treatment doctor to know the swallowing disorder degree after the patient swallows the training. The professional treatment doctor only needs to compare the swallowing disorder degree before the swallowing training with the swallowing disorder degree after the swallowing training (intuitively, the electric signal before the swallowing training is compared with the electric signal after the swallowing training), and the improvement degree of the swallowing training instrument on the swallowing disorder of the patient can be known, so that the labor intensity of the professional treatment doctor is reduced.
More specifically, with respect to the selection of the pressure sensor of the present application, the present application considers that most pressure sensors are currently fabricated by integrated circuit processes, specifically by a pressure sensitive element, sandwiching a silicon fiber baffle between a silicon frame and a diaphragm structure composed of a gold-chromium film. However, the pressure sensor is greatly affected by temperature, i.e. a temperature drift phenomenon easily occurs, and the temperature drift phenomenon can cause an incomplete linear relation of output electric signals, i.e. cause the problems of low or high amplitude and the like of the output electric signals, thereby reducing the detection accuracy. Therefore, the pressure sensor of the application does not adopt a pressure sensor manufactured by an integrated circuit process, but adopts the piezoresistive pressure sensor 1 which is less influenced by temperature (for example, the piezoresistive pressure sensor of the MPS-2100 series can be selected, can be input by constant voltage or constant current, has excellent performance and long-time stability, has a wider temperature operation range of-40 ℃ to 85 ℃), and improves the detection accuracy.
The utility model provides a swallow training appearance, include: the piezoresistive pressure sensor is placed in the throat of a patient during swallowing detection of the patient, and is used for detecting the motion force of the throat muscle of the patient during swallowing of food of the patient and generating an electric signal for representing the motion force; a laryngeal muscle trainer to be placed in the throat of a patient during swallowing training; the controller is respectively connected with the output end of the piezoresistive pressure sensor, the control end of the laryngeal muscle trainer and the upper computer and is used for controlling the laryngeal muscle trainer to train the laryngeal muscles of the patient after receiving the swallowing training instruction; when swallowing detection is carried out on a patient, the electric signal is uploaded to an upper computer to be displayed for a professional treating doctor to check.
It is thus clear that the training appearance of swallowing of this application not only has the function of training patient's laryngeal muscle, still have the function of detecting patient's laryngeal muscle motion dynamics (the dyskinesia degree that patient's laryngeal muscle has been embodied in the motion dynamics of patient's laryngeal muscle, the motion dynamics is less, the dysswallowing is more serious), so the training appearance of swallowing of this application can detect the dynamics of motion of patient's laryngeal muscle around training patient's laryngeal muscle respectively, and can pass on the signal of telecommunication of sign dynamics of motion to the host computer supplies professional treatment doctor to look over, professional treatment doctor only needs the signal of telecommunication around the contrast training patient's laryngeal muscle, alright know the improvement degree of the training appearance to patient's dysswallowing, thereby professional treatment doctor's intensity of labour has been.
