Description

The present invention visualizes an electric signal from a pressure sensor capable of measuring the pressure applied to the human body during the operation such as palpation, massage, and care without using a complicated circuit. The present invention relates to a device and a human body model incorporating the pressure visualization device.

  In the act of directly touching the human body such as palpation, massage, and care, it is important to know which part of the subject is touched with what level of force, that is, pressure. For example, in palpation and massage, it is necessary to learn the position to be treated and the adjustment of the acupressure. Moreover, in nursing care, it is necessary to be able to grasp the level of force so that excessive pressure does not place an excessive burden on the subject. Traditionally, methods for acquiring these various techniques have been carried out by the trainer imitating the model of the instructor, but the various techniques are largely dependent on individual skills, and the level of power is sensuous and ambiguous. It was difficult to convey the technology to the trainees in an easy-to-understand manner. In addition, preparation of subjects to be practiced was also necessary.

  In response to this problem, an apparatus for quantitatively evaluating a massage technique without actually performing treatment on a subject has been proposed (see Patent Document 1). In this proposal, the subject is replaced with a simulated human body with a built-in pressure sensor, and the practitioner's technique is evaluated by inputting the pressure measured by the sensor to the technique evaluation apparatus. There has also been a proposal for acquiring massage techniques with a simple and inexpensive apparatus that omits the technique evaluation device (see Patent Document 2).

However, in the system of Patent Document 1, the evaluation result of the procedure is displayed on the display of the procedure evaluation device, but it is not only troublesome to read the evaluation result but also diverts the line of sight from the subject. It contributes to the loss of efficiency. In addition, the pressure can be detected with a single 6-axis sensor embedded in the cervical vertebrae. However, in order to evaluate the data detected by the 6-axis sensor as pressure, a computing device such as a personal computer is required, making the system complicated. There is a problem that it is costly.

On the other hand, the apparatus of Patent Document 2 can practice a massage technique more easily and inexpensively, but cannot obtain an objective evaluation of the technique.

Accordingly, the present invention has been devised to solve the above-described problems and to enable application in a wider range of fields. The object is to provide a device that can easily recognize and intuitively understand the pressure applied to the human body by various treatments with a simpler and less expensive configuration.

In order to solve the above problems, the present invention has a built-in pressure sensor that can be worn on a practitioner's finger and the like, and a pressure visualization device that visually displays a color corresponding to the magnitude of an electric signal from the pressure sensor. The structure which consists of the human body model which imitated each part of the human body was taken.

Here, the method for transmitting the electrical signal from the pressure sensor to the pressure visualization device may be wired electrical connection or wireless communication using radio waves.

The pressure sensor emits an electric signal having a magnitude proportional to the pressure, and includes a mechanism for transmitting the electric signal to a pressure visualization device built in the human body model. For example, a rubber band-like shape is attached to a portion that comes into contact with the human body model imitating the subject. Various sensors that are currently applied in various fields can be applied to pressure sensors that generate electrical signals according to the strength of the pressure, but in order to adopt a configuration located between the operator's finger and the human body model. It is desirable to have a certain degree of flexibility so that the human body model can be felt.

Furthermore, the human body model imitates the part of the human body to be treated, and is designed to be equal in size and shape to the actual human body. It is desirable that the surface of the human body model be covered with a material such as silicon rubber, in order to resemble the feeling of an actual person during treatment.

In addition, the pressure visualization device built in the human body model emits light of a color that continuously changes according to the electrical signal measured by the pressure sensor that emits an electrical signal having a magnitude proportional to the magnitude of the pressure. The human body model covering the device itself appears to emit its color, thereby informing the strength of the pressure due to the treatment.

As an effect of the present invention, only one inexpensive pressure sensor is required for this apparatus, and a complicated arithmetic unit is not required for pressure evaluation. Therefore, the pressure applied to the human body with a simple and inexpensive configuration. It becomes possible to know. In addition, because the human body model to be treated itself notifies the pressure by light, the user can intuitively know the pressure applied to the subject by his own treatment without taking his eyes off the treatment target, As a result, efficient real-time practice that combines treatment and evaluation becomes possible. Furthermore, since the present invention relates to a human body model and evaluation of pressure applied to the human body model, it is applicable not only to massage but also to exercises such as palpation and care operation.

Schematic diagram of the present invention Circuit diagram of sensor unit

  Hereinafter, the best embodiment of the present invention will be described with reference to the drawings. Although various embodiments of the present invention can be considered, the following description will be made taking application to face massage as an example.

FIG. 1 shows a schematic configuration when the present invention is applied to face massage. The treatment evaluation system 1 includes a sensor unit 2 incorporating a pressure sensor, a pressure visualization device 3 capable of receiving pressure data from the sensor unit 2, and a human body model 4 incorporating the pressure visualization device 3.

The sensor 2 is for measuring the pressure of the treatment, and is attached to the finger performing the treatment. When the practitioner performs treatment with the finger wearing the sensor, the sensor 2 is sandwiched between the practitioner's finger and the subject, and an electric signal corresponding to the strength of the pressure is generated. An electrical signal from the pressure sensor is transmitted to the pressure visualization device 3, and the pressure visualization device 3 emits light corresponding to the magnitude of the electrical signal.

The human body model 4 simulates the shape and size of an actual human body, and its skeleton is made of a transparent material such as acrylic resin. Its surface layer has elasticity close to that of the human body and can transmit light to some extent. It is covered with a material such as silicon rubber. The human body model 4 has a built-in pressure table visualization device 3 and is configured so that light emitted from the pressure visualization device 3 can be seen from the outside.

Continuing on from the above, the application to the practice of face massage will be described as an example.

When practicing with an instructor, the instructor first attaches the sensor unit 2 to the finger performing the operation and performs an appropriate operation. Then, light corresponding to the appropriate pressure is emitted from the pressure visualization device and can be confirmed from the outside through the human body model 4. Therefore, the practitioner can know the appropriate pressure as the corresponding color.

After the instructor's example, the practitioner, like the instructor, attaches the sensor part to the finger performing the treatment, and massages the same part where the instructor performed the operation. At this time, if a force is applied so that the human body model emits light of the same color as the model by the previous lecturer, it can be determined that the power of the treatment is appropriate.

By repeating the above process, the practitioner can sensuously acquire appropriate force at each point of the massage, and the massage skill that has been relied on the skill of the practitioner can be easily applied to the practitioner. It becomes possible to convey.
