Infrared arm circumference measurement instrument

Abstract

The invention discloses an infrared arm circumference measurement instrument. The measurement instrument comprises a pressure sensing armlet, an infrared detection ring, an elbow right-angle ruler, a supporting device, a pressure display screen and an arm circumference display screen, wherein a pressure sensor is arranged inside the pressure sensing armlet, the pressure display screen is arranged outside the pressure sensing armlet, and pressure sensed by the pressure sensor can be displayed on the pressure display screen; the pressure sensing armlet is connected with the infrared detection ring through the supporting device; a plurality of infrared distance measuring sensors are uniformly arranged on the inner side of the infrared detection ring; a processor is arranged in the infrared detection ring, and is used for processing signals detected by the infrared distance measuring sensors to obtain arm circumference data and displaying the arm circumference data on the arm circumference display screen outside the infrared detection ring; and one end of the elbow right-angle ruler is connected with the pressure sensing armlet. The infrared arm circumference measurement instrument is novel in structure and convenient to use, can be used for solving the current clinical problem that the arm circumference measured by human factors is not accurate and improving the precision and efficiency of measurement, and provides reliable basis for clinical detection and arm swelling treatment.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to an infrared arm circumference measuring instrument for measuring arm circumference. Background technique [0002] Lymphedema refers to edema in a certain part of the human body due to lymphatic fluid retention caused by a defect in the lymphatic system. Pathogenesis Surgical injury and lymph node cancer metastasis interrupt the lymphatic return path of the upper arm, the protein concentration in the interstitial fluid increases, the filtration pressure increases, and the decrease in plasma protein reduces the colloid osmotic pressure difference, while the capillary permeability increases and is rich in protein Lymph fluid can stimulate the proliferation of fibroblasts in the interstitial tissue and release collagen, and the function of macrophages is inhibited, unable to degrade and digest collagen, and fibrosis occurs in the subcutaneous tissue. Early lymphedema is re...

Problems solved by technology

Although current technical equipment has made it relatively easy to implement and measure controlled spillage, its use is still limited: First, the issue of sensitivity was once questioned because sufficient edema would need to occur to cause measurable spillage. Second, it cannot reflect the location and shape of local edema, and patients often complain that it is difficult to maintain the posture and wait for the fluid to overflow
