An integrated automatic blood-squeezing peripheral blood glucose detection device

Abstract

The application discloses an integrated automatic blood-squeezing peripheral blood glucose detection device, which comprises a host computer (1) and a detachably connected disposable sterile integrated core (2). The disposable sterile integrated core (2) comprises a microneedle assembly (4), an elastic squeezing structure (3) arranged around the microneedle assembly (4), a blood glucose detection test paper (6), a capillary blood guiding channel (5) and an electrode contact (7). When the microneedle assembly (4) completes skin puncture, the elastic squeezing structure (3) applies synchronous micro mechanical squeezing force to the tissue around the blood sampling site, so that blood seeps out and is automatically transported to the blood glucose detection test paper (6) through the capillary blood guiding channel (5). The blood glucose detection test paper (6) is internally integrated in the disposable sterile integrated core (2), and the electrode contact (7) is used for electrical connection with the host computer (1). The application realizes the integration of blood sampling, automatic blood squeezing, blood guiding and detection by using a pure mechanical structure, and does not need manual blood squeezing and manual sample adding. The application has the advantages of simple structure, low cost, simple operation, safety and sanitation, and is suitable for rapid blood glucose detection in family and hospital scenes.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a peripheral blood detection device that integrates blood collection, blood squeezing, blood conduction and blood glucose detection functions. Background Technology

[0002] Currently, most rapid blood glucose testing devices used in clinical and home settings employ a separate lancing device and test strip design, which presents the following problems in practical use: After blood collection, you need to manually squeeze your fingertip to obtain a blood sample. Uneven squeezing force can easily lead to insufficient bleeding, hemolysis, or significant pain. The test strips need to be picked up and inserted separately, which is a complicated procedure and can easily cause contamination of the test strips or cross-contamination of blood. It is difficult for the elderly, children, and people with mobility impairments to operate; In hospital settings, nurses' operational efficiency is low and the risk of infection control is high.

[0003] Existing integrated blood collection devices mostly use motors, negative pressure, or complex transmission structures, which are costly and unreliable. They also fail to achieve synchronous triggering of blood collection and elastic squeezing actions, and do not integrate microneedles, elastic squeezing structures, test strips, and capillary channels into the same disposable core, making it difficult to meet the actual needs of low cost, high reliability, and easy mass production. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an integrated automatic blood squeezing capillary blood glucose testing device, which solves the problems of traditional blood glucose meters requiring manual blood squeezing, cumbersome operation, easy contamination, complex structure, and high cost. Technical solution

[0005] An integrated automatic blood squeezing capillary blood glucose testing device includes a main unit (1) and a detachable disposable sterile integrated core (2). The disposable sterile integrated core (2) includes an elastic extrusion structure (3), a microneedle assembly (4), a capillary blood conduction channel (5), a blood glucose test strip (6), and electrode contacts (7). The elastic compression structure (3) is arranged around the periphery of the microneedle assembly (4) and is configured to apply synchronous, minute, and uniform mechanical compression force to the tissue around the blood collection site while the microneedle assembly (4) completes skin puncture. The capillary blood conduction channel (5) directly connects the blood collection area and the reaction area of ​​the blood glucose test strip (6), and achieves automatic blood transmission by relying on capillary force; The blood glucose test strip (6) is entirely built into the disposable sterile integrated core (2), and does not need to be removed, connected, or manually added during use; The electrode contact (7) is located at the rear end of the blood glucose test strip (6) and is used to electrically connect with the host (1) to transmit the detection signal; The entire device uses a purely mechanical structure to perform blood collection and squeezing actions, and does not include motors, electromagnets, air pumps, or negative pressure drive components.

[0006] Work process Unpack the individual sterile packaging and assemble the disposable sterile integrated core (2) into the main unit (1); The integrated core front contact head is pressed tightly against the skin of the fingertip, and the elastic extrusion structure (3) forms a pre-compression; Trigger host (1), microneedle component (4) completes skin puncture; The elastic compression structure (3) applies compression force simultaneously, and blood naturally seeps out; Blood is automatically delivered to the blood glucose test strip (6) via capillary blood conduction channel (5); The host (1) reads the detection signal and displays the blood glucose concentration through the electrode contacts (7); After the test is completed, the disposable sterile integrated core (2) is removed and discarded as a whole. Beneficial effects

[0007] It achieves simultaneous blood collection and automatic blood squeezing, resulting in stable bleeding volume and low pain, thus solving the pain points of manual blood squeezing. The microneedle, elastic blood squeezing structure, test strip, capillary channel and electrode contact are integrated into one, allowing for true one-press testing; It is a purely mechanical, non-powered structure with simple structure, high reliability, low production cost, and easy mass production. The disposable sterile sealed design prevents the needle from being exposed and blood from coming into contact with the hands, greatly reducing the risk of contamination and making it suitable for use in hospitals and homes. The operation steps are extremely simple and can be completed with one hand, making it convenient for all ages and medical staff to use. Attached Figure Description
