An integrated implant device for an implantable biosensor

Abstract

The present invention discloses an integrated implantation device for an implantable biosensor. Before triggering, the bottom surface of the sliding seat is pressed against the human skin, pressing the main shell to start the trigger, and the main shell drives the fixed seat to move downward relative to the sliding seat, that is, the sliding seat slides upward relative to the fixed seat, and the protruding bone position slides from the lower end of the bone position slide groove to its upper end. Since the first clamping protrusion of the needle member is clamped in the bone position slide groove, it does not slide relative to the fixed seat, so that the needle member slides downward relative to the sliding seat to realize the needle-piercing action; when the protruding bone position slides from the lower end of the bone position slide groove to the upper end thereof, the first clamping protrusion of the needle member is pushed out, and the spring begins to release freely, pushing the needle member to move away from the skin to realize needle extraction, and the edge of the top wall of the sliding seat pushes the second clamping protrusion to both sides, the cantilever resistance beam loses its resistance to the sliding seat, and the needle member reaches the upper limit stable position. The structure adopts an integrated design, will not be triggered by mistake, and has good structural stability.

Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and in particular to an integrated implant device for an implantable biosensor. Background Art

[0002] Diabetes is a group of metabolic diseases characterized by high blood sugar. High blood sugar is caused by defects in insulin secretion or its biological function, or both. Long-term high blood sugar leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves. With the increasing incidence of diabetes, diabetes has become a public health problem worldwide.

[0003] At present, blood sugar monitoring is an important part of diabetes management. Managing the patient's blood sugar can significantly reduce the risk of diabetic complications. The industry has invented CGM (Continuous Glucose Monitoring), a monitoring technology that monitors the glucose concentration of subcutaneous tissue fluid through a glucose sensor and indirectly reflects the blood sugar level. It can provide continuous, comprehensive and reliable blood sugar information throughout the day, understand the trend of blood sugar fluctuations, and discover hidden hyperglycemia and hypoglycemia that are not easily detected by traditional monitoring methods.

[0004] For the diabetic population, traditional fingertip blood glucose meters have shortcomings such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations and provide warnings. They can no longer meet the needs of some people, especially type 1 diabetes patients who have real-time transmission requirements for blood glucose fluctuations and type 2 diabetes patients who require intensive insulin treatment.

[0005] Due to the need for continuous blood glucose monitoring, an implantable biosensor is required to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in the tissue fluid is a continuous monitoring method that can be used in reality. Its single service life is one to two weeks, which greatly reduces the pain caused by the process of continuous fingertip blood collection and venous blood collection. Currently, such implantable devices on the market have problems such as complex user operation, long implantation process, and easy mis-triggering of the push device, which leads to reduced user compliance and experience.

[0006] The implantable biosensor implantable device in the prior art is split, has poor structural stability, and is prone to false triggering. Summary of the invention

[0007] In view of the above, the present invention provides an integrated implant device for an implantable biosensor with good structural stability.

The first locking protrusion (421) of the fixing seat (1) of the member (4) is pushed out from the bone position slide groove (131) of the fixing seat (1), and the needle member (4) is freed from restraint. Under the action of the restoring force of the spring (5), the needle member (4) moves away from the skin to achieve the needle withdrawal action. The edge of the top wall of the sliding seat (2) pushes the second locking protrusion (33321) of the main shell (3) to both sides, and the cantilever abutting beam (3332) loses its abutting effect on the sliding seat (2). When the top surface of the needle member (4) abuts against the bottom surface of the main shell (3), it reaches the upper limit position, and the needle withdrawal is completed.
