Description

Multi-functional electronic reading ruler for legal medical expert

Technical Field

The utility model relates to a measure technical field, specifically be a multi-functional electronic reading chi is used to legal medical expert.

Background

During forensic necropsy or biopsy, examination of wounds or scars is very common, and length, width, depth and scar length measurements of wounds are closely related to inference of injurious substances, inference of causes of death, assessment of degree of injury and degree of disability.

(I) existing measurement products

Currently, the following devices are commonly available on the market for measuring wounds or scars:

the first is a single-sided adhesive scale. The ruler is the most commonly used device for measuring the length or width of a wound or a scar by a forensic doctor, and is mostly made of paper. When in use, the ruler can be used for being taken off and pasted beside a wound or a scar, and can be bent along the scale surface of the ruler. However, the ruler is generally not waterproof and disposable, the use convenience is limited by the dryness and cleanness of the adhesive and the sticking part on the back, the depth of the wound cannot be measured, and the ruler cannot be bent perpendicular to the scale surface of the ruler, so that the wound or scar with irregular shape cannot be measured. The ruler has certain ductility, the back of the ruler is easy to stick together, and very accurate measurement cannot be carried out.

The second is a steel rule. The ruler is durable, accurate in measurement and accurate in working, and can pass inspection and calibration. However, the ruler can only measure straight lines, cannot be bent along with body surface radians, and further cannot accurately measure irregular-shaped wounds and scars. The width of the steel ruler is more money, and only can measure great wound depth, and in the forensic practice, the wound that meets the wound depth that needs to measure is mostly less, consequently also can't be used for the measurement of wound depth effectively.

The third is a tape measure. The ruler may be of steel or plastic material. However, the degree of bending is as same as that of a single-sided adhesive type graduated scale, and the graduated scale can only be bent along the graduated surface of the graduated scale and cannot be bent randomly along with the shape of a wound or a scar. The ruler can not be fixed into a scar shape during measurement, has a large caliber, and can not be effectively used for measuring the wound depth.

(II) conventional measurement method

For irregular scars or wound length and width, or wound depth, no product is currently available in forensic practice, and the following methods are mainly used for measurement:

1. measurement of irregular scar or wound length and width

(1) The traditional steel ruler or the single-sided adhesive type graduated scale is used, the ruler direction is changed continuously according to the scar or the shape of the wound in a manual mode, and therefore the length of the wound or the scar is estimated. The result measured by this method can only be an estimate. Accuracy cannot be achieved. For accurate measurements to be required to determine the extent of injury, disability or to infer the length of a cross-section of an injurious agent, it is clear that the measurement results are not convincing. This is also a reason why the length of the scar is liable to cause disputes in the case of legal medical living body.

(2) Soft material, such as wool, is used, laid out according to the length of the scar, finally straightened and measured with a ruler. The method is more accurate than the former method, but the lines are not easy to fix beside the scar and have certain flexibility, and the fixing position and the shape of the lines beside the scar can be influenced by slight movement of an operator or a detected person or wind blowing in the external environment, so the use is inconvenient and inaccurate.

2. Measurement of wound depth

In the field of forensic practice, the depth of a wound to be measured is generally small, and the starting end of measurement cannot be checked by naked eyes, so that an object with certain hardness is required to be used for probing, and the depth of the wound is measured. A flexible material ruler such as a single-sided adhesive scale or a tape measure cannot be applied to such depth measurement. Most of depth measuring rulers on the market at present are wide, sharp in head and not suitable for depth measurement of soft tissues of human bodies.

(III) disadvantages of the existing products and techniques

Summarizing the existing products and techniques, scar or wound length, width and depth measurement devices and methods for use in the forensic field have the following disadvantages:

1. the application range of the used existing product is small, and the product is only limited to a linear wound or a scar which is linear or is bent along with the radian of the body surface;

2. no device is available for irregular scar measurement;

3. the traditional method for measuring the length and the width of the irregular scars or the wounds is inaccurate and difficult to operate, the measurement result has certain randomness, and the measurement result is lack of rigor as the basis for checking and identifying;

4. there are no devices specifically adapted for measuring wound depth;

the reading is estimated by the measuring personnel, and a large error exists.
