Description

[Detailed Description of the Invention] The present invention relates to a device for measuring swelling of the upper limbs, lower limbs, neck, etc. of a human body.

When collecting data for clinical evaluation related to swelling treatment, conventionally, marks are placed on the skin at the measurement site, and once a day, for example, the outer diameter and circumference of the swelling area are measured with caliper-like scissors or a tape measure. was measuring. However, there is a risk that the measurement location may differ slightly from measurement to measurement, resulting in inaccurate data.
The use of tape measures, calipers, etc. had the disadvantage of causing pain to patients.

The purpose of this invention is to accurately determine the measurement location and measurement direction based on the back of the foot, palm, chin, etc.
An object of the present invention is to provide a swelling measuring instrument capable of simultaneously measuring an outer diameter and a circumferential length.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention for measuring swelling of upper and lower limbs.

An elevating guide plate 2 with a scale C attached to the side edge of the base 1 is fixed with screws, and a vertical groove 3 of this guide plate 2 is fitted with a clamp 4 that can be raised and lowered, and the fixing screw at the back allows it to be adjusted to any desired height. It is fixed in place. The clamp holder 4 has
A horizontal guide groove is provided for slidably holding the scissor scale 5.

As shown in the plan view in FIG. 3, the scissor scale 5 includes a straight fixed scale 51 and a fixed jaw 5 that is bent into a hook shape from one end of the fixed scale 51.
2, and a movable jaw 53 that is slidably supported by a fixed scale 51 and whose facing distance changes while facing the fixed jaw 52, and the lengths of the fixed jaw 52 and the movable jaw 53 are the same as the upper limb of the human body to be measured, Greater than the radius of the lower limb or neck. The fixed scale 51 is engraved with a scale A similar to the main scale of a normal caliper, and the distance between the fixed jaw 52 and the movable jaw 53 can be measured. Hooks 54 and 55 are provided at a predetermined point P at the tip of the fixed jaw 52 and at a point substantially corresponding to the point P at the tip of the movable jaw 53, and one end of the string 6 is fixed to the hook 54, A weight 7 is provided at the other end of the string 6. This string 6 is fixed to the circumference to be measured 52
A mark 61 is attached at a predetermined length, for example, exactly 50 cm from the fixed end. The fixed jaw 52 is engraved with a scale B that starts from a point P toward the base and starts at, for example, 50 cm and decreases in a negative direction. Also, point P
A notch 8 for guiding the string 6 is formed at a position where a straight line parallel to the scissor surface of the fixed jaw 52 intersects with the edge of the fixed length 51.

Insert the base 56 of the movable jaw 53 of the scissor scale 5 into the guide groove of the scissor holder 4 and tighten the fixing screw 1.
3, the fixed length 51 and the fixed jaw 5 are fixed.
2 comes to slide relative to the base 1.

Next, how to use it will be explained.

The height of the clamping tool 4 is fixed according to the measurement site and the scale C is read. Next, the fixed jaw 52 and the movable jaw 5
Between 3 and 3, hold the part to be measured, for example, the lower leg, and mark A on the scale.
I Read. At the same time, the string 6 is wound around the lower limbs, hung on the hooks 54 and 55, passed through the notch 8, and the weight 7 is suspended as shown in the figure, and the position of the mark 61 at this time is read on the scale B. In this way, the scale A measures the outer diameter, the scale B measures the circumference, and the scale C measures, for example, the height from the sole of the foot to the measurement site.

FIG. 2 shows another embodiment of the present invention. This example measures cervical swelling.

The lifting guide plate 2, the clamping tool 4, and the scissor scale 5 of the above-described embodiment are fixed to the side edge of the base 1 so that the fixed jaw 52 and variable jaw 53 of the scissor scale 5 face outward. Attach the small lifting guide plate 9 to the screw 1
It is fixed at 0, and a scale D is carved along the vertical groove 11 of the small elevating guide plate 9, and a pedestal 12 that can be raised and lowered is fitted into the groove 11 and fixed at an arbitrary height by a fixing screw at the back. Ru. When using this embodiment, the subject's chin is placed on the pedestal 12, the head is fixed, and the neck is held between two scissor scales using the same method as in the previous embodiment. Neck diameter and neck circumference can be measured.

According to the present invention, a string with a mark attached to a predetermined position and a weight at the tip is attached to a scissors measure, the string is wrapped around the measurement site, and the outer diameter and circumference are measured with the weight suspended. Since the length can be read, the circumference can be accurately measured even for areas with non-circular outlines, and the tension of the string is always constant, allowing accurate measurements without causing pain to the patient. be able to. In addition, since the scissor scale is supported in a predetermined positional relationship to the substrate that supports the object to be measured, such as the base on which the feet are placed and the pedestal on which the chin is placed, it is extremely easy to identify the correct position, and the reliability is improved. High data can be obtained. Furthermore, according to the present invention, a negative scale B is attached starting from a predetermined point of the fixed jaw toward the base at a predetermined length, for example, 50 cm, and the mark on the string is read by this scale B. Since there is no need to mark the scale on the string, a thin string with a circular cross section can be used, which not only significantly reduces the patient's pain, but also makes it easier and more accurate to read the scale B.
