Outpatient body fluid collecting and processing device

Abstract

The invention discloses an outpatient body fluid collecting and processing device. The device comprises a bottom plate, a heat preservation sleeve is fixedly connected to the bottom plate, a heat preservation layer is arranged on the outer side wall of the heat preservation sleeve, an annular cavity is formed in the heat preservation sleeve, an exhaust hole is formed in the bottom of the annular cavity, an annular plug is slidably connected into the annular cavity, pull rods are symmetrically and fixedly connected to the annular plug, a cover plate is fixedly connected to the ends, penetratingout of the annular cavity, of the pull rods, the heat preservation sleeve is provided with a storage cavity, an isolation sleeve is placed in the storage cavity, and a push rod is slidably inserted into the isolation sleeve in a penetrating mode. According to the invention, a communicating pipe is connected to an external liquefied nitrogen input pipe, the cover plate is pressed to enable the annular plug to move downwards, liquefied nitrogen is injected into the annular cavity through the communicating pipe, after the cover plate tightly covers the heat preservation sleeve, a sealing plug isscrewed to the communicating pipe through to complete sealing, the interior of the storage cavity is kept at a low temperature, and meanwhile due to the fact that the heat preservation sleeve is lightproof, the storage cavity is used for long-term storage of samples.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an outpatient body fluid collection and processing device. Background technique [0002] Body fluid is the general term for all fluids in the human body. Body fluids make up about 60% of an adult's body weight. In addition to water, body fluids contain many ions and other compounds. Extracellular fluid is the internal environment that cells rely on for survival. Physiological regulation of body fluids Humor regulation is that some cells in the body produce certain special chemical substances, which are transported by the blood circulation to reach various organs and tissues of the body or a certain organ and tissue, thereby Cause some special reactions of this organ tissue. Various hormones secreted by many endocrine cells regulate the functions of the body through the pathway of body fluid circulation. For example, insulin secreted by pancreatic islet B cells can reg...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that "the samples after collection are placed in the first pipe and the second pipe are easily affected by external conditions such as light and temperature, and cannot effectively store body fluid samples for a long time. Due to the shortcoming that specimens are stored for too long and are easy to be inactivated, which will affect subsequent detection, a device for collecting and processing body fluids in outpatient clinics is proposed.
