Description

sweat collection cap

technical field

The present invention relates to a sweat collection cap.

Background technique

Sweat is a fluid secreted by sweat glands. There are many types of inorganic and organic components in sweat. When the human body is infected with a certain disease or ingests a certain substance, the composition of sweat produced by metabolism will change. Therefore, the detection and analysis of sweat components can contribute to the development of disease diagnosis, doping detection and anti-drug law enforcement. In recent years, metabolomics and nondestructive testing have become research hotspots. Compared with traditional diagnostic testing methods, metabolomics and nondestructive testing have significant advantages, and their application prospects are promising.

Although there are many kinds of existing sweat collection devices, there are generally a series of problems such as the small amount of sweat collected, the sweat collection process takes a long time, the operation is complicated, and the composition of the collected sweat is quite different from that secreted by sweat glands. In order to promote sweating, the commonly used methods are injection of pilocarpine (alias: pilocarpine) and strenuous exercise.

Injection of pilocarpine has toxic and side effects and requires professional medical personnel to operate, and irregular use may easily lead to medical accidents. The drug circulates throughout the body of the recipient with the body fluid, causing adverse reactions such as extensive sweating and physical discomfort.

The strenuous exercise method can be used for daily high-intensity exercise or sweat collection detection and analysis during/after labor, but it is not suitable for disease detection of patients and pre-match detection of athletes. High-intensity activities can easily lead to aggravation of the patient's condition, cause fatigue of athletes, and affect competition performance.

Chinese patent CN201520257815.8 proposes a sweat collector for laboratories, which is similar to a syringe. The collector involved in this patent first transfers sweat to the straw through a sweat head, and then discharges the sweat from the sweat tube on the straw. Due to the small size of the sweat-absorbing head, this patent is not suitable for testing items that require a large amount of sweat.

Chinese patent CN201520085922.7 proposes a sweat collector for inspection. The collector involved in this patent has a cylindrical shape, uses the sampling cotton on the round roller to collect sweat on the skin, and squeezes the horizontal plate to squeeze the sweat out of the sampling cotton. This patent is only applicable when the subject is sweating a lot, and there is a defect that the sampling cotton absorbs sweat components.

Chinese patent CN201320604412.7 proposes a head and face sweat remover. The sweat remover that this patent relates to is used for holding the sweat that joint face discharges. In the process of collecting sweat by using the device, more sweat evaporates, and the sweat concentration varies greatly due to different evaporation intensities.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the present invention proposes a sweat collection cap.

The end of the liquid outlet pipe on the liquid collecting ring of the present invention is trumpet-shaped. The elastic liquid collection bag is made of natural rubber and has good elasticity. Therefore, the elastic liquid collection bag is relatively firm when installed on the liquid collection ring, and it is also relatively convenient to disassemble.

The present invention selects soft polyvinyl chloride material to make the closed hat top, and is applicable to different head shapes.

The present invention selects natural rubber to make elastic liquid collection bag for use. The elastic liquid collection bag has good airtightness, which can prevent the collected sweat from being polluted and ensure that the collected sweat will not be lost.

The top of the closed cap and the inner wall of the liquid collecting ring are smooth, which reduces the flow resistance of sweat and facilitates the confluence and collection of sweat.

Working process of the present invention is as follows:

Firstly, the elastic liquid collection bag is installed on the liquid outlet pipe, and the person to be tested wears the sweat collection cap of the present invention, and a closed space is formed between the sweat collection cap and the head; since the hair has the function of heat preservation, the temperature inside the cap continues to rise, Prompt head perspiration; head perspiration leads to increased humidity inside the cap, which further promotes head perspiration; a small part of the sweat from the head diffuses into the confined space in the form of steam, and condenses into liquid inside the sweat collection cap It is drop-shaped and flows into the liquid collection circle; most of the sweat directly flows into the liquid collection circle in liquid form; the sweat in the liquid collection circle is finally collected into the elastic collection bag through the sweat tube.

The sweat collection cap of the present invention creates an airtight environment for collecting sweat, the heat emitted by the head is not easy to lose, the temperature inside the collection cap increases, and the perspiration is promoted; the perspiration of the head causes the humidity in the collection cap to increase, which further promotes the sweating of the head. Perspiration; the sweat collection cap is simple in structure, easy to wear and use, and has a wide range of applications; compared with other sweat collection methods, this method is more comfortable, more convenient to collect sweat, and the collected sweat is more consistent with the sweat components discharged from the sweat glands. near.
