Description
Technical Field
The invention belongs to the technical field of temperature control devices, and particularly relates to an ice box for detecting a vascular response cold index, a device and a method.
Background
At present, with the continuous promotion of polar development, the frequent activities of human beings in cold regions such as high altitude and high altitude of plateau lead to the increasing chance of human body entering (exposing) cold environment. Therefore, before entering cold regions, it is important to promote the cold resistance of the body and to add cold habit clothes to the body. The main current way to evaluate the cold resistance of the body is the Vascular Response Cold Index (VRCI). VRCI is a method of soaking the middle finger of the left hand in ice-water mixture at 0 deg.C, and monitoring the real-time change of the finger tip temperature in the process (20 min). The experiment can objectively evaluate the contractility of the blood vessels of the organism to the cold environment, and further reflect the cold resistance of the organism. The key point in the VRCI detection process is the requirement for the environmental temperature, and the finger soaking temperature is ensured to be maintained at 0 ℃ in the detection process.
The original method uses an ice-water mixture to meet the requirement of 0 ℃ of the environment, but the process has a plurality of defects and has higher requirement on the external environment. The defects comprise that: 1) although the temperature of the ice-water mixture is considered to be 0 ℃, the temperature of ice and water in different proportions changes, and in different ice-water proportions, the time for maintaining the temperature to reach the stable temperature (0 ℃) is uncertain, so that a longer time is needed for preparation in the detection process; 2) the requirement of the ice-water mixture on the external environment is strict, and the maintaining time of different temperatures, wind speeds and humidity on the ice-water mixture at 0 ℃ is different, so that the temperature of the operation environment needs to be kept consistent in the detection process, but the requirement is difficult to realize, so that the finger soaking temperature cannot be maintained at 0 ℃ in the detection process, and the accuracy of the result is influenced; 3) the present detection is highly dependent on ice. In order to ensure that the finger soaking temperature is maintained at 0 ℃, sufficient ice needs to be prepared, and more people cannot be detected on a large scale under the limited refrigeration condition, so that the rapid evaluation of the crowd cold adaptation level for VRCI detection is a great defect; 4) the detection environment is influenced, water overflows in the using process, and the detection environment is seriously influenced. Because the detection process is relatively long (20 minutes), the testee inevitably swings when soaking fingers in the ice-water mixture, so that water overflows outwards (in order to ensure the maintenance of 0 ℃, the fingers fully invade into the water, the water surface is generally required to reach the edge of the container), the detection environment is seriously influenced, the ground is slippery, and the falling and damage of the testee are easily caused.
