Rapid blood glucose monitoring needle

Abstract

The invention discloses a rapid blood glucose monitoring needle. The rapid blood glucose monitoring needle is used in cooperation with a remaining needle. The rapid blood glucose monitoring needle comprises a needle seat, a protective cap, a monitoring needle body and test paper. The needle seat comprises a needle seat inner cavity and an air cabin located on the side wall of the needle seat inner cavity and formed by a movable plate. The air cabin is communicated with the needle seat inner cavity through a connector arranged on the side wall of the needle seat inner cavity, a blood sampling groove is formed in the front end of the test paper and stretches into the needle seat inner cavity, the rear end of the test paper is provided with an induction sheet connected with a blood glucose meter, the induction sheet is arranged on the outer side of the needle seat inner cavity, the monitoring needle body is fixed to the front end of the needle seat and communicated with the needle seat, and the front end of the monitoring needle body penetrates through the protective cap detachably connected with the remaining needle and then stretches into a soft catheter of the remaining needle. Due to the fact that blood is sampled through the remaining needle, a blood sample is tested on a site, repeated puncture on the skin of a patient is avoided, the monitoring rate of vein blood glucose is greatly increased, and the mistaken puncture harm to an operator is avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a painless and rapid venous blood sugar monitoring needle. Background technique [0002] At present, there are two main methods of blood glucose monitoring widely used clinically, fingertip blood glucose monitoring and venous blood glucose monitoring. Fingertip blood glucose monitoring is fast and convenient. For example, a blood glucose meter using the glucose oxidase electrode measurement method can detect the result within 30 seconds and the required blood sample volume is very small, less than 5 microliters. However, the extraction of blood samples needs to be punctured with a fingertip needle, and the puncture points are limited to very few parts such as the ring finger and the middle finger. Often, the wound left by the last puncture has not healed, and a new wound must be punctured again. Frequent punctures can easily cause continuous pain at the puncture site, difficulty in wound heal...

AI Technical Summary

Problems solved by technology

Under frequent puncture, it is easy to cause continuous pain at the puncture site, difficulty in wound healing or complications

These have increased the pain of the patient. On the other hand, since the skin needs to be disinfected with alcohol before the puncture, in order to avoid contamination of the blood sample and affect the test results, the first drop of blood must be discarded when taking blood. This is in case of poor blood supply. The patient has to moderately squeeze the punctured finger to take blood, which not only increases the risk of the operator coming into contact with the patient's blood, but also affects the blood glucose test results, which brings troubles to the clinical operators; venous blood glucose monitoring is the current clinical practice. The gold standard for blood sugar monitoring, but it takes a long time to test, and it takes at least 2-3 hours to get the test results. It cannot give timely feedback on the patient's blood sugar situation at that time, and is not suitable for daily monitoring of blood sugar of patients.

In addition, venous blood glucose monitoring also has problems such as repeated punctures, which is undoubtedly an unbearable pain for patients who need to monitor blood glucose multiple times a day

[0003] In addition, the blood collection needles commonly used in clinical practice to detect venous blood sugar are still exposed after use, which can easily puncture medical staff and threaten the life and health of medical staff. Pollution
