Description

Technical Field

[0001] The utility model relates to the technical field of sepsis sample detection and adsorption, in particular to a sample detection and adsorption device that is easy to use. Background Art

[0002] Sepsis is a serious infectious disease, usually caused by bacteria. It can occur throughout the body, leading to a systemic inflammatory response. Symptoms include fever, chills, hypotension, increased heart rate, rapid breathing, changes in consciousness, etc. The mortality rate of sepsis has now exceeded that of myocardial infarction, becoming the leading cause of death among non-cardiac patients in intensive care units. In the process of treating sepsis patients, sample detection and adsorption equipment is often needed. The sepsis sample detection and adsorption equipment is a device used to adsorb and enrich the body fluids of sepsis patients. The samples collected by the device are used for the detection and analysis of pathogenic microorganisms, inflammatory factors, etc., so as to help doctors understand the patient's condition and formulate corresponding treatment plans.

[0003] Common sample detection and adsorption devices are similar to syringes. When medical staff use sample detection and adsorption devices, they usually insert the needle into the position in the patient's body where liquid needs to be extracted, and extract the required liquid in the patient's body into the cylinder of the detection and adsorption device. During the suction process, the medical staff needs to hold the outer shell and pull the movable rod outward. When pulling the movable rod, since the needle and the outer shell do not have a fixed fulcrum, it is easy to cause shaking and trembling when pulling the movable rod outward, which can easily affect the stability of the needle when aspirating samples.

[0004] Therefore, those skilled in the art provide an easy-to-use sample detection adsorption device to solve the problems raised in the above background technology. Utility Model Content
