Device for collecting and storing sweat specimens

Abstract

The invention belongs to the field of detection devices, and specifically discloses a device for collecting and storing sweat specimens. The device includes a collection unit and a separation unit, wherein the collection unit includes a waterproof layer, a hydrophilic substance cladding which is arranged on the waterproof layer, a skin-friendly layer and a protective layer, the skin-friendly layeris arranged on the hydrophilic substance cladding, and the protective layer is adhered to both ends of the inner surface of the waterproof layer, and is detachably arranged on the waterproof layer; aplurality of air holes are formed in the skin-friendly layer, a sweat stimulant is adsorbed on the hydrophilic substance cladding, and the separation unit includes an outer tube, an inner tube and atube plug; the inner tube is placed inside the outer tube, the tube plug is placed on the upper end of the inner tube, and the upper part of the outer tube is capable of clamping the tube body of theinner tube so as to prevent the inner tube from slipping off; and multiple meshes for filtering out sweat are formed in the lower part of the inner tube. Through the device, sweat at any parts can becollected for a long time, the collection amount is large, and the sweat specimens are collected and stored, so that the sweat is analyzed more accurately, and feedback of the indicator conditions ofthe human body is obtained.

Description

technical field [0001] The invention belongs to the field of detection devices, in particular to a device for collecting and storing sweat samples. Background technique [0002] With the increasing focus on health, people's demand for monitoring various indicators of the body has grown by leaps and bounds. The detection of blood, tissue fluid or sweat can be used to track and grasp the health status of the body. The detection of blood and tissue fluid will cause certain damage to the body, so Non-invasive detection using sweat is a trend. Human sweat contains sodium, chloride, lactic acid, urea and small amounts of proteins, peptides and metal ions. The components in sweat can reflect the health status of the human body. For example: dehydration, cystic fibrosis, pancreatic disease in children, etc. At the same time, the collection of human sweat is also used in high-temperature training by athletes or troops, especially when wearing protective equipment, a large amount o...

Problems solved by technology

People often use the nude weight difference method before and after exercise, the clothed weight difference method and the gauze weight gain method to express the amount of sweat to reflect the human body's weight-bearing limit, which cannot accurately reflect the physical condition of athletes or soldiers

[0003] Chinese patent CN2910156Y discloses a sweat collection bag, which solves the problem that the sweat from the doctor's forehead easily drips into the operation area during the surgical operation and causes pollution

It includes a sweat-absorbing layer and a fastening body. The outer and bottom sides of the sweat-absorbing layer are provided with a waterproof layer, and a liquid collection chamber is provided at the end of the sweat-absorbing layer, but the collection bag cannot be conveniently placed on other parts of the body. Perform sweat collection and storage analysis

[0004] Traditional sweat collectors use sweat-absorbing materials to scrape and collect the skin. First of all, it is impossible to accurately know when and where the sweat is sweated, and it cannot effectively collect sweat from the skin for a long time, and the collection volume is very small. Therefore, the detected results are not accurate
