Description

Device for detecting the location of a point of pulses in hands}

The present invention relates to a detection device for detecting the exact position of the Mac, and more specifically, to accurately detect the position of the village, the tubular part, the chuck part inside the wrist to be the target of the pulse to determine the physical condition of the subject It relates to a vein position detection device.

In oriental medicine and oriental medicine, pulse diagnosis is used to diagnose diseases of the examinee by measuring pulses of the coronary, coronal, and vertebral parts, which are specific positions on the arteries located inside the wrist. The pulse method is to measure the harmony of the blood and blood flow through the human body to measure the functional presence of the twelve, mainly the strength of the pulse (pressure strength and weakness), Determination of the state of health by sensing the cycle.

However, these pulses require long-term medical experiences, and because the treatment of the patient's condition and the severity of the disease depends on the sense of the finger, it is difficult to systematically organize the various conditions according to the patient's constitution. There are many concerns. In addition, in order to prescribe according to the patient's constitution, objective data is required, but it is true that the specification is difficult.

In order to solve the above problems, conventionally, a device for manually detecting a pulse wave by attaching a pulse wave detection sensor for pressure measurement to the radial artery of the wrist, wrapping the cuff of a blood pressure monitor and applying air pressure by hand, has been devised. However, the device cannot determine whether the pulse wave detection sensor is correctly located in the radial artery, and when the cuff is released after the measurement, the pulse wave is often detected at a different position out of the measurement position. In addition, since the whole wrist was pressed with a cuff, it was difficult to obtain a normal pulse wave waveform.

In order to alleviate this drawback, an apparatus for automatically detecting pulse waves caused by three levels of pressure by driving three sensor rods with a stepping motor is disclosed. However, the pulse wave detection device using a sensor rod has a problem that can not accurately detect the pulse point. In other words, if the doctor correctly detects the point of contact and touches the ends of the three sensor rods, there is no problem, but in the unskilled state, the position of the pulse is not accurately located and even if a slight error occurs, the accurate measurement cannot be detected. However, since this climax requires mastery for a long time, even the doctors did not fully acquire the problem of deteriorating the accuracy of the climax.

The present invention is to solve the above problems, an object of the present invention is a true position detection device capable of accurately detecting the true position for the pulse measurement of the three points, located in the wrist, the coronal part, the chuck part of the examinee To provide.

Another object of the present invention is to provide a true position detection device that can measure the accurate pulse pressure and period by maintaining a constant pressure of the pressure sensor in contact with the inner skin of the wrist.

It is another object of the present invention to provide a pulse pressure measuring apparatus which has a structure capable of correcting a pressure change caused by wrist movement occurring during tremor and can be used for detecting a tremor position.

In particular, the central rod 60 has a screw thread formed on the surface and is connected to the rotating shaft of the geared motor 52 to rotate simultaneously with the rotation of the geared motor 52. Due to the rotational force of the central rod 60, the vertical moving part 50 moves up and down, and thus the horizontal moving part 30 moves up and down. On the other hand, the slide rod 58 has no thread on the surface and allows the horizontal moving unit 30 to move stably at the same time as Shanghai.

For the combination of the central rod 60 and the horizontal moving unit 30, referring to Figure 3, the horizontal moving unit 30 on the upper surface of the guide box 62 through which the central rod 60 and the sliding rod 58 penetrates The upper fixing plate 32 of) is coupled.
