Description
Technical Field
The invention relates to a medical auxiliary instrument, in particular to an upper limb circumference fixed point measuring device.
Background
Lymphedema is one of the most important problems after breast cancer surgery, not only can cause shoulder joint dysfunction and appearance change of affected limbs, but also can negatively affect the psychology and work life of patients, and the quality of life of breast cancer patients is reduced. The incidence of lymphedema varies greatly, from 5% to 56%, due to inconsistent definition and evaluation criteria. An accurate measuring tool and an effective evaluation mode are necessary means for preventing and judging the curative effect of lymphedema.
The most widely used measuring methods internationally at present include: arm circumference measurement, water displacement, blood loss meter (Perometer), bioelectrical impedance spectroscopy (Bioimpedance Spectroscopy, BIS). The water displacement method measures the volume of the upper limb through drainage, but the process is tedious and time-consuming. The Peromeer measures the upper limb volume by infrared rays, but the equipment is expensive and the measurement accuracy is not advantageous compared with the traditional girth measurement. BIS can accurately distinguish the change of intracellular fluid and extracellular fluid, is commonly used for early detection of lymphedema, but the device cannot directly measure the upper limb volume, is frequently used together with upper limb volume measuring equipment clinically, and has higher price.
The method currently recommended and widely used both internationally and domestically is the girth measurement method, by which the volume is calculated. The equipment required by the method is very simple, and a tape measure or a flexible rule can be used. The following problems still remain:
1) Before each measurement, marks are needed to be made on the patient, and the marks are measured one by using a flexible rule, so that time and labor are wasted, and the clinical efficiency is severely limited;
2) The requirements for the measuring personnel are high. Because the texture of human tissue is soft, if the pulling force applied to the tape during measurement is inconsistent before and after measurement, the measurement result difference can be caused. The existing solution is to keep the tension of the front and back measurement pair end flexible rule consistent by relying on experience of the same therapist intuitively, but the measurement re-measurement reliability is low due to the fact that unified standards and standardized equipment are not provided, and the improvement is needed;
3) For patients with lymphedema of the upper limbs, the position relationship between the upper limbs and the level has a certain influence on the upper limb volume. If the upper limb sags during measurement, the edema degree of the upper limb is aggravated and the volume is increased due to the gravity effect. Therefore, it is important to maintain a uniform measurement position before and after measurement. There is no particularly good method at present, and experienced therapists usually sit upright with the trunk bent forward and at an angle of 90 degrees to the body, and perform fixed point measurements at this position, but the above-mentioned body position is difficult to maintain for a long time during measurement.
