Description
Technical Field
The utility model relates to a human blood sugar monitoring or detection area, concretely relates to last glucose monitoring system's implantation device.
Background
As the global population becomes older and chronic diseases grow larger, more control is needed for the treatment of various diseases, including monitoring the physical condition of patients and making real-time and correct responses.
For example, Diabetes mellitus, a chronic disease affecting the elderly, develops very rapidly, and according to data of IDF Diabetes Adtlaseelevation Edition 2017 published by International Diabetes Federation (IDF) 2017, the population of Diabetes mellitus worldwide in 2017 is 4.25, most of which is concentrated in India, China, USA, Russia and Japan, and the data of 2045 years is expected to increase to 6.29 billion.
Continuous Glucose Monitoring Systems (CGMs) are comprised of sensors, signal emitters, signal reading systems, and the like. By inserting the sensor under the skin of the patient, the system can record the subcutaneous glucose concentration of the user, transmit the subcutaneous glucose concentration to the signal reading system, and draw a glucose concentration curve during monitoring, provide a blood glucose concentration curve of 7 days to 14 days continuously, and monitor the change of the blood glucose concentration in the body well. Multiple random control experimental studies prove that the CGMs are helpful for improving the blood sugar control of type 1 and type 2 diabetes patients, remarkably reducing the level of glycosylated hemoglobin (HbA1c), and improving the standard reaching rate of HbA1 c. Studies have shown that CGMs reduce the incidence of hypoglycemia in type 2 diabetic patients, and at 12 months, the daily incidence of patients with blood glucose below 3.9, 3.1, 2.5mmol/L is reduced by 41%, 56%, and 62% from baseline, respectively, and studies have shown that the higher the CGMs monitoring frequency, the longer the time within the patient's blood glucose reach standard (TIR), and the shorter the hypoglycemia time, the better glycemic control.
Currently, commercially available continuous glucose monitoring systems are packaged as separate emitters and sensors and need to be assembled before being implanted into a human body.

First, push button 1
As shown in fig. 2, the button 1 includes a cover plate 102 and at least one insert 101, the insert 101 being connected to the cover plate 102.
As shown in fig. 1, when the button 1 is in the initial state, the cover plate 102 may protrude from the housing 2, the insert 101 may extend into the housing 2, and the button 1 and the housing 2 are stationary relative to each other.
When the button 1 is switched from the initial state to the operating state, the cover plate 102 is pressed, and the insert 101 moves in a direction close to the body surface of the human body with respect to the housing 2. Such as when the button 1, the housing 2 are in the up-down arrangement shown in fig. 1, the button 1 moves downward relative to the housing 2. For another example, when the button 1 and the housing 2 are laterally arranged, the button 1 moves horizontally relative to the housing 2.
The number of the inserts 101 is not particularly limited and is not limited to three shown in the drawings.
The number of the inserts 101 is set according to actual needs, and the following conditions are met:
In the process that insert 101 removes along being close to human body surface direction, an terminal surface of insert 101 gradually with warp 4 contact and with warp 4 whole outwards strut or local inwards shrink and local outwards strut, lead to emitter 7 to break away from warp 4, realize finally that sensor 9 inserts internally and emitter 7 fixes at the body surface.
There are various ways for the insert 101 to separate the deformation member 4 from the launcher 7, one is that during the downward movement of the insert 101, the whole deformation member 4 is outwardly expanded, the support bracket 402 of the deformation member 4 is gradually moved outward, so that the deformation member 4 is gradually switched from supporting the launcher 7 to separating from the launcher 7; one is that during the downward movement of the insert 101, the deformable element 4 is partially retracted inwards and partially expanded outwards, the support bracket 402 of the deformable element 4 being gradually moved outwards, so that the deformable element 4 is gradually switched from supporting the emitter 7 to disengaging from the emitter 7.
Ideally, as shown in fig. 9, the deformation element 4 does not need to be provided with a support bracket 402, and in the initial state, the inner wall of the deformation element 4 is in contact with the outer wall of the emitter 7, and due to the friction force between the two, the two are relatively static, and the deformation element 4 can also play a role of supporting the emitter 7.

The projection of the bottom end 10111 of the inclined surface 1011 on the horizontal plane is positioned outside the deformation piece 4, and the projection of the top end 10112 of the inclined surface 1011 on the horizontal plane is positioned inside the deformation piece 4.
The deformation element 4 can be of an oval configuration as shown in fig. 9. Both ends of the short axis of the initial state of the shaping member 4 support the emitter 7, and the emitter 7 may be additionally supported by the support bracket 402.
When the connecting line of the two inserts 101 coincides with the long axis of the deformation member 4, and the inclined surface 1011 moves downward, as shown by arrows in fig. 9, the two ends of the long axis of the deformation member 4 are pressed to contract inward, and the two ends of the short axis of the deformation member 4 are spread outward, so that the emitter 7 is released in the spreading process.
In summary, the present invention provides the button 1 with the purpose that the insert 101 deforms the deformation element 4 during the pressing of the button 1 from the initial position, so that the deformation element 4 is separated from the emitter 7.
(III) of course, the utility model discloses also can not set up button 1 and realize the deformation of deformation 4, direct manual extrusion deformation 4.
