Description

A kind of stretchable length soft ruler

technical field

The utility model relates to the field of length measuring rulers, in particular to a flexible length measuring ruler.

Background technique

When doctors check lumbar spondylosis, they often measure the range of motion of the patient's lumbar spine. The range of motion of the lumbar spine is: the difference between the selected length of the patient's lumbar spine when bending over and stretching and the length when standing upright. The length selected when standing upright is the selected length of the lumbar spine. Usually, a length of the lumbar spine is selected from the intersection point of the patient's upright posterior superior iliac spine and the spine toward the cervical spine, and the patient is asked to lean forward and bend over. The lumbar spine of this selected length is stretched to a new length, and the stretched new The difference between the length and the selected length is the range of motion of the patient's lumbar spine based on the selected length. Doctors can use the activity of the patient's lumbar spine to judge the condition of the patient's lumbar spine.

The tape measure in the prior art includes a box body, a soft ruler, a shaft fixedly arranged in the box body, a roll holder and a stretching opening arranged on the box body; the roll holder is rotatably assembled with the shaft, and the soft ruler Wrapped on the roll holder, the stretched end of the tape stretches out of the box through the stretch opening on the box body; there is a scale indicating the length on the tape, and the scale is stretched at the stretch end of the tape. Start marking for zero. The method of using a tape measure to measure the activity of the patient's lumbar spine is as follows: the patient stands upright, finds the starting point on the lumbar spine, and sets the stretch end of the tape measure at the starting point; stretches the tape measure along the direction of the cervical spine to the selected length, and fixes the box at the selected point. Length: Let the patient lean forward and bend down, the tape measure is stretched again, read the scale value of the tape measure, the difference between the scale value and the selected length is the range of motion of the patient's lumbar spine based on the selected length. In the process of using the tape measure, the tape measure must first be stretched to the selected length. After the measurement is completed, the difference between the final stretched length and the selected length needs to be calculated. The measurement process is cumbersome.
