Lancet device and method for sampling and injecting blood using the lancet device

Abstract

The present invention provides a blood collection needle device, which includes a blood collection needle chamber and a blood outlet, and the blood collection needle device can extract a required amount from the skin of mammals including humans through the vacuum mechanism or capillary mechanism of the blood collection needle device. blood, temporarily stores the blood, and injects the blood into a blood chamber in the blood analysis and diagnosis device through an injection port of the blood analysis and diagnosis device such as a digital bio disc (DBD) and a lab-on-a-chip.

Description

technical field [0001] The present invention relates to a blood sampling device, in particular to a blood collection needle device (lancetdevice) for taking a small amount of blood samples required by blood analysis and diagnosis equipment, such as digital biodisk (DBD) and lab-on-a-chip; The blood collection needle device is a method for taking blood samples and injecting blood. The lancet device and the method can be widely used in disease testing or blood sugar testing of diabetic patients. Background technique [0002] Lancet devices for piercing human skin are already known. For example, various lancet devices with good results have been used in outpatient departments of medical institutions, hospitals, Red Cross hospitals, and emergency organizations for taking small blood samples for blood testing. The portion of the lancet that pierces the human skin must be continuously kept sterile. The part of the lancet device that is injected into the tissue to a predetermine...

AI Technical Summary

Problems solved by technology

First, it is difficult to draw as sufficient and constant blood volume as required

Second, it is difficult to inject blood drawn from wounds into blood analysis and diagnostic equipment such as digital bio discs (DBD, digital bio disc) and lab-on-a-chip (Lab-on-a-chip)

First, when the blood is withdrawn, the cap provided at the end of the vacuum blood collection needle device is stained with blood, so the cap may be contaminated

Therefore, it is difficult to avoid the loss of drawn blood

Second, recently, AIDS has become widespread, so the use of needles may lead to the spread of the disease

In addition, when the non-disposable cap provided at the end of the vacuum lancet device is contaminated by an infected person, the re-use of the vacuum lancet device may have fatal consequences
