Piston type portable detection system for blood of human body

Abstract

The invention discloses a piston type portable detection system for blood of a human body, which comprises a sensor set, a central processor, a blood sample collection system, a blood sample detection system and a vein retention body. A retention body which can be retained in a vein is adopted; interval time of sampling blood samples is set through the central processor; the blood samples are collected through the blood sample collection system, and are delivered to the blood sample detection system; and the blood sample collection system applied to the clinical can perform painless, controllable and uninterrupted monitoring, blood sample collection and blood sample detection on the blood of the human body; therefore, relatively complete information of the blood of a patient is acquired, and the pathological and physiological states of the human body can be dynamically understood in real time in a whole. In the invention, technical difficulties of influencing subsequent continuous monitoring, wounding the patient and the like due to the blood coagulation and the deposition of substances such as proteins and the like in the blood are avoided; as the blood is sampled from a capillary, the blood sampling quantity is extremely less; the safety range of the health of the human body cannot be damaged; and the portable detection system has a significant meaning for directing clinicaltreatment.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device for monitoring, collecting and testing human blood. Background technique [0002] In addition to cell components, human blood contains proteins, non-protein nitrogenous substances, lipids, sugars, other organic substances (including vitamins, enzymes, coagulation and anticoagulation factors, etc.), and inorganic substances in liquid plasma. In order to adapt to the needs of the body, a large amount of information about the condition of the human body can be learned from the blood of the human body. [0003] In the prior art, when blood needs to be monitored and tested, blood samples are often detected clinically through venous blood drawing and rapid fingertip peripheral blood, and the purpose of detection is achieved through repeated acupuncture blood sampling, which increases the suffering of patients and makes medical work more difficult. The workload of the worker increas...

Problems solved by technology

In clinical practice, the detection of hormone levels in the body is also a commonly used detection item. However, many hormones in the body are secreted in pulses and have a basal secretion state. A simple one-time blood sample cannot reflect the true levels of various hormones in the body, and may even cause wrong test results, bringing wrong information to clinical diagnosis and treatment

What's more, in most critically ill patients, multiple blood tests are required to understand the patient's pathological information, guide treatment, and evaluate the prognosis. Some patients even cause bleeding at the puncture point. When the condition suddenly changes and aggravates, the blood sample cannot be collected successfully due to insufficient blood volume and blood vessel collapse. The daily blood volume may cause the patient to develop anemia in a short period of time.
