Description

  The present invention relates to a rehabilitation tool used for training of recovery of eating / swallowing function, particularly tongue function.

  Eating and swallowing functions may be impaired in people with brain damage due to stroke or in elderly people with senile dementia. As a training for recovery of the eating / swallowing function for a patient having such eating / swallowing disorders, there are a direct training for actually eating food and an indirect training performed without giving food.

  Among these, the latter indirect training does not have to worry about food entering the trachea due to aspiration, and in this respect, it is considered safer than the former direct training. As specific indirect training, training for inducing swallowing by applying physical stimulation to a swallowing induction site such as a soft palate, a tongue base, and a posterior pharyngeal wall is known. A dedicated instrument for stimulating a swallowing induction site has also been developed (see, for example, Patent Document 1).

  In addition, the movement of the tongue is deeply involved in the eating and swallowing functions, and if the pressure (tongue pressure) when pressing the tongue against the palate is not more than a certain level, it is difficult to form a bolus and feed it into the pharynx Become. For this reason, the measurement of tongue pressure is conventionally performed using the tongue pressure measuring device (for example, refer patent document 2).

  Furthermore, since improvement in tongue pressure leads to recovery of eating and swallowing functions, the tongue pressure measurement device is used to allow the patient to repeatedly press the tongue against the palate to improve tongue muscle strength. Indirect training has also been proposed (for example, Non-Patent Documents 1 and 2).

Joanne Robbins and 5 others "The Effects of Lingual Exercise on Swallowing in Older Adults" JAGS (J. Am Geriatr. Soc., American Geriatrics Society, September 2005, 53, 9, p. 1483-1489 Urihara Uri and eight others, "Cases of oral cancer with tongue movement rehabilitation using a disposable probe (33rd Academic Conference)", Japanese Society for Stomatognathic Function, Japan Journal of Stomatognathic Function, 2005, No. Volume 11, Issue 2, P158-159

  However, in training to stimulate the swallowing trigger location, the swallowing trigger location is in the back of the mouth, so caregivers without medical knowledge and patients with reduced motor function can identify the exact location of the swallowing trigger site. It is difficult to do. Therefore, even if a dedicated instrument is used, it is extremely difficult for a person other than the medical staff to perform the training by accurately stimulating the swallowing induction site.

  On the other hand, in training for the purpose of improving the muscle strength of the tongue, it is considered that the sensor portion of the tongue pressure measuring device only needs to be sandwiched between the tongue and the palate, and the above-described problems do not occur. However, the tongue pressure measuring device is not originally designed for the purpose of rehabilitation, and is a device premised on being operated by a medical worker. For this reason, there exists a problem that it is unusable especially when a patient performs training by himself.

  Furthermore, it is preferable to perform training for the purpose of improving the muscle strength of the tongue anytime and anywhere, but the tongue pressure measuring device does not consider carrying. For this reason, development of a dedicated instrument that can be carried anywhere is required.

  An object of the present invention is to provide a rehabilitation tool for use in recovery training for a swallowing function (particularly the tongue function) that solves the above problems, is easy to carry, and has excellent operability.

  As described above, in the rehabilitation tool of the present invention, the angle of the insertion portion to be inserted into the patient's oral cavity is variable. Therefore, according to the rehabilitation tool of the present invention, even the patient himself / herself with a reduced motor function can easily guide the elastic member at the distal end of the insertion portion between the tongue and the palate. The rehabilitation tool is excellent in operability. Moreover, since the rehabilitation tool of the present invention has a simple configuration and is easy to carry, the caregiver and the patient can perform recovery training anytime, anywhere.

The three-way valve 29 connects between the tube member 23 and the tube member 31 or between the tube member 23 and the tube member 30 in accordance with an instruction from the control unit 28.

  The pressure detection unit 27 converts the pressure transmitted through the pipe members 23 and 31 into an electrical signal, and outputs the obtained electrical signal to the control unit 28. When the pressure detection unit 27 outputs an electrical signal, the control unit 28 specifies an output value of the electrical signal and obtains an actual pressure from the specified output value. Further, the control unit 28 displays the obtained pressure on the display screen of the display display 32. Thus, the rehabilitation tool in Embodiment 1 can also be used as a probe for a tongue pressure measuring device.

  The pressurizing unit 26 includes a pressurizing mechanism such as a pump or a syringe, and pressurizes the internal pressure of the elastic member (balloon) 8 to be a set pressure in accordance with an instruction from the control unit 28. When the internal pressure set value of the elastic member 8 is input from the user, the control unit 28 switches the valve flow path and operates the pressurizing unit 26 so that the internal pressure becomes the set value. Further, at this time, the control unit 28 also displays the input set value on the display screen of the display display 32.
