Description

[0001] O-RING TEST APPARATUS [0002]

The present invention relates to an O-ring test apparatus for sifting, and it is an object of the present invention to provide an O-ring test apparatus for classifying the constitution by measuring the change of the gripping force of the subject by objective data using a sensor for sensing pressure, The present invention relates to an O-ring test apparatus for testing an O-ring.

The O-Ring Test was developed by Dr. Omura Yoshiaki, a Japanese born medical scientist, and published in New York in the early 1970s. It is a special diagnostic method in which the harmful effects of certain substances on the human body It is a diagnostic method to find by intensity. The O-ring test is a test to determine whether the subject has made an O-shaped thumb and index finger of his right hand, placed a specific object on his left hand, and then opened the finger of the subject with both hands. Detects changes in gripping force.

Recently, the principle of O - ring test method which reacts to a specific substance has been used as an auxiliary diagnostic method for distinguishing the constitution of a patient based on the sagittal constitutional medicine theory in Oriental medicine.

However, o-ring testing is challenging and requires the old diagnostic experience and skill of the tester.

In addition, the force with which the human muscles can exert is not always constant, and the muscular strength that maintains the constant force is gradually reduced, resulting in an error, which makes it impossible to make an accurate judgment.

For this purpose, Korean Patent Registration No. 20-0422392 discloses contents of measuring the gripping force using a pressure sensor in order to obtain objective data of an O-ring test.

In addition, devices for correcting the gripping force of the subject by using the correction means to correct the change of the gripping force or by using an auxiliary means such as a motor have been developed to induce the measurement point for accurate measurement.

However, the measurement method using the pressure sensor can measure the gripping force of the subject objectively, but the examiner could not directly detect the change of the gripping force of the subject.

Therefore, the examiner must judge the change of the gripping force of the examinee only by using the simple measurement value, so that it is difficult to accurately discriminate the constitution.

On the other hand, in the O-ring test, when the metal material is brought into contact with the body of the examinee, different influences are exerted on the examinee depending on the specific metal material, and the test results may be different.

Accordingly, when the test unit 100 is formed of a metallic material, the metallic material changes the body of the examinee so as to affect the test result. Therefore, in order to prevent the influence of the metallic material on the testee, The first measurement bar 120 and the second measurement bar 130, which are in direct contact with the body of the first measurement bar 130, are formed of a synthetic resin material.

3, an intermediate member is provided between the first measuring bar 120 and the second measuring bar 130 to minimize rotational friction.

At this time, the intermediate member may be a bearing for reducing the rotational friction force between the first measurement bar 120 and the second measurement bar 130.

Here, the bearing may be any one of a variety of bearings such as a ball bearing, a roller bearing, and the like.

3, the second measurement bar 130 includes an extension 131 protruding from an end of the second measurement bar 130 to be in contact with the sensor unit 160 .

Hereinafter, the specific function of the extension member 131 will be described in detail with reference to FIG. 5 to be described later.

Meanwhile, the first measurement bar 120 and the second measurement bar 130 are provided at one side thereof with a subject grip unit 140 so that the subject can grip the subject with a finger.

In order to enable the examiner to grasp the gripping force of the examinee by holding the finger on the other side of the first measurement bar 120 and the second measurement bar 130 in opposition to the examinee's grip section 140, (150).

The inspector sensing unit 150 may include a first sensing grip 152 and a second sensing grip 151. The first sensing grip 152 may be coupled to the first sensing grip 152, And the second sensing grip 151 is formed on the other side of the second measuring bar 130 in opposition to the second gripping grip 141. The second sensing bar 151 is formed on the other side of the first measuring bar 120,

The rotation angle of the examinee grip portion 140 increases as the height of the measurement bar increases with the height of the first measurement bar 120 and the second measurement bar 130, The second sensing grip 151 can no longer be rotated downward by the first sensing grip 152 when the second measuring bar 130 is rotated.

Accordingly, when the inspecting person sensing unit 150 contacts the first sensing grip 152 and the second sensing grip 151, the first measuring bar 120 and the second measuring bar 130 The rotation angle of the examinee's gripper 140 is not sufficiently secured.

Therefore, when the first sensing grip 152 and the second sensing grip 151 are brought into contact with each other, the inspectors' sensing unit 150 may be provided with a plate- The first measurement bar 120 and the second measurement bar 130 may be disposed at the lower end of one side of the first measurement bar 120 and the second measurement bar 130, respectively.

Here, the pressing member 161 receives pressure by the extension member 131 and presses the pressing member 161 against the sensor unit 160.

In this case, when the second measuring bar 130 rotates to press the pressing member 161, the pressing member 161 secures a moving distance due to the holding of the examinee, The second gripping grip 141 is moved in a direction in which the second gripping grip 141 is in contact with the sensor unit 160 so that the extension member 131 and the sensor unit 160 are in contact with each other, As shown in FIG.

Meanwhile, the sensor unit 160 can objectively measure the change rate and the maximum value of the gripping force of the subject.

However, in the O-ring test, not only the maximum value of the gripping force of the subject but also the resistance of the subject to the external force is also an important factor in determining the constitution.

Therefore, in the o-ring testing apparatus according to the embodiment of the present invention, the ocular ring testing apparatus further includes the inspector sensing unit 150 to grasp not only the maximum value of the gripping force of the examinee but also the resistance reaction by the external force, The inspector sensing unit 150 includes the first sensing grip 152 and the second sensing grip 151.
