Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the invention, and is not intended to exhaust all possible ways of practicing the invention, nor is it intended to limit the scope of the invention.
As shown in fig. 1a, 1b, 2a and 2b, the present disclosure provides an analyte sensing system that includes a base 8, a sensor module 4 and an emitter module 7 (i.e., an electronic processing module). The sensor module 4 is used to bind to a living body, such as a human body, and detect an analyte in the body, such as a blood glucose concentration or the like. The sensor module 4 is used in cooperation with the transmitter module 7, the transmitter module 7 comprises a circuit board 204 and a power supply 207, the transmitter module 7 receives and processes the electrical signals formed by the sensor module 4 and transmits the electrical signals to the outside for use, and the power supply 207 supplies power to various electronic components on the circuit board 204 and the sensor module 4.
It will be appreciated that the analyte sensing system is generally flat, with the "thickness direction" being the direction in which it is implanted into the body in use, the side closer to the body being the "lower side" or "distal side" and the side further from the body being the "upper side" or "proximal side". The analyte sensing system has an axial direction co-directional with the "thickness direction", a radial direction perpendicular to the "thickness direction", and a circumferential direction corresponding to the axial direction and the radial direction. In fig. 1a and 2a, the U direction is the up/proximal side and the D direction is the down/distal side.
The base 8 includes a hollow mounting portion 800, a relief portion 900, and a joint portion 700, which are arranged in a plane perpendicular to the thickness direction of the analyte sensing system, and a base body for connecting the three into a whole is provided therebetween. The mounting portion 800 has a hollow space to mount the sensor module 4, and the sensor module 4 is mounted or bonded, for example, with interference with an inner peripheral wall of the mounting portion 800. The bypass portion 900 is a hole penetrating from top to bottom (in the thickness direction) for accommodating the power supply 207, and the bypass portion 900 may form a notch at an edge of the base 8. The joint part 700 is a hole which is communicated from top to bottom and is used for being clamped with the emitter module 7, the emitter module 7 is stably installed and is not easy to fall off, a user can conveniently assemble and disassemble, and the avoiding part 900 is not communicated with the joint part 700.
The base body between installation department 800, dodge portion 900 and the joint part 700 three is only used for connecting the three into a whole to occupy less projection area, for example, be less than installation department 800, dodge portion 900 and the total projection area of the joint part 700 three, thereby base 8 forms hollow out construction. The hollowed-out base 8 is light in weight, saves materials, and is beneficial to light weight of the analyte sensing system, and the installation part 800, the avoiding part 900 and the joint part 700 enable the analyte sensing system to provide a more optimized installation position for the emitter module 7, so that the thinning of the whole structure is facilitated.
Specifically, the mounting portion 800 and the relief portion 900 may occupy a circumferential space having a central angle of 80 to 100 degrees and a radial space from the center to the edge of the base 8 of 85% or more, respectively. The junction 700 between the relief 900 and the mounting 800 portion may occupy at least 25% of the space between the relief 900 and the mounting 800 portion.
Therefore, the base 8 is hollowed out in a large area, and the weight of the base 8 is reduced.
As shown in fig. 2a to 4b, the circuit board 204 is provided with a power supply holder 205, and the power supply holder 205 is made of a conductive material, for example, metal. The power supply bracket 205 lifts the power supply 207 to be positioned below the circuit board 204, the power supply 207 does not substantially occupy the mounting space of the circuit board 204, and the power supply 207 is electrically connected to the electronic components on the circuit board 204 through the power supply bracket 205. The power supply bracket 205 is welded with the power supply 207 and is welded to the reserved position of the circuit board 204 through pins, so that a more stable and difficult-to-loosen assembly structure is realized, and the long-time continuous work of a product is ensured.
In this way, the circuit board 204 below the power supply 207 may be used to mount electronic components and a larger size power supply 207 may be used, thereby making the electronic component spacing and circuit board 204 layout more reasonable while achieving a longer endurance. In addition, the circuit board 204 without the integrated power supply 207 is simpler to manufacture, reducing the manufacturing difficulty of the analyte sensing system. The power supply 207 protruding from the circuit board 204 can be accommodated in a relief portion of the base 8, thereby reducing the thickness of the analyte sensing system, which satisfies the requirement of miniaturization.
With the analyte sensing system, a larger volume of power supply can be installed, extending the duration of the flight to, for example, 45 to 90 days.
The circuit board 204 integrates electronic components such as a pin (e.g., pogo pin 201), a data test point 202, a data processing chip 203, an Application Specific Integrated Circuit (ASIC) module 208, a Micro Control Unit (MCU) module 206, and a bluetooth data processing module 209. The circuit board 204 functions to position, connect, and secure all electronic components. The spring pin 201 is fixed at a predetermined connection position of the circuit board 204 by soldering, so that it is more stable during repeated triggering and assembling processes, thereby stably transmitting a signal stream to, for example, the sensor module 4.
The data test points 202 mainly perform functions of functional verification test, correction and the like on corresponding test partitions, the data processing chip 203 is fixed in a reserved area in a conventional patch mode, mainly processes specific logic operation of data of the sensor module 4, transmits the data and temporarily stores the data participating in the operation, and corresponding functions are completed through an internal data transmission bus and a general register. The asic module 208 is a dedicated ic, which can quickly respond and operate data, so that the operation efficiency of the product is more efficient. The multi-point control unit module 206 mainly processes, diagnoses and calculates various data of different information sources, controls and transmits the data to the bluetooth data processing module 209, and transmits the data to the receiving terminal in a bluetooth mode after data conversion.
The multi-point control unit module 206 may be disposed on the circuit board 204 above the power supply 207. During transport, the power supply 207 is supported by the power support 205 above the multi-point control unit module 206 (the transmitter module is inverted during transport), reducing the risk of damage to the multi-point control unit module 206 due to forces on the transmitter module 7.
The power supply 207 and the electronic components are located on the same side of the circuit board 204, which facilitates the thinning of the system.
The transmitter module 7 further comprises a housing comprising an upper cover 3 and a bottom cover 1. The bottom cover 1 is provided with a buckling part 101, and the buckling part 101 is buckled with the joint part 700 in the hollow space of the joint part 700.

The power supply housing 107 protrudes from a portion of the main housing such that structure can be provided on the main housing 109 for connection to other portions of the analyte sensing system (e.g., the sensor module 4) with greater effectiveness in accommodating non-regularly shaped features, greater design space savings and assembly space savings, and an aid in miniaturizing the analyte sensing system.
The number of the snap-in portions 101 and the engaging portions 700 is the same, for example, two. Two snap-in portions 101 may be located on both sides of the power supply housing 107, and correspondingly, two engaging portions 700 may be located on both sides of the bypass portion 900. When the emitter module 7 is assembled with the base 8 and the sensor module 4, the two buckling parts 101 and the power supply housing 107 which are arranged on the bottom cover 1 are respectively embedded and assembled with the hollow joint part 700 and the avoiding part 900. The 'three-point' embedded layout is adopted, the assembly stability can be improved, the falling risk of a product in use is reduced, and the emitter module 7 and the base 8 are combined more closely and harmoniously.
The bottom cover 1 mainly provides a space structure for positioning and supporting the power supply 207, the circuit board 204 and the electronic components thereof. For example, two latching portions 101 are circumferentially spaced approximately 180 degrees apart, and the proximal ends of the latching portions 101 are connected to the main housing 109 and the distal ends are freely disposed, so that the latching portions 101 are formed as cantilever structures with the distal ends thereof being free ends. The locking part 101 can be elastically deformed by an external force to clamp or release the joint part 700, specifically, the distal end of the locking part 101 is radially displaced, and the locking structure is simple and occupies a small operation space.
The sensor module 4 includes an elastic sealing block 403 and electrical contacts, the elastic sealing block 403 has windows capable of being electrically connected to the electrical contacts, and the electrical contacts of the circuit board 204, such as the pogo pins 201, are elastically and electrically connected to the electrical contacts of the sensor module 4 through the windows, which is simple in structure. The positioning groove 103 of the bottom cover 1 accommodates the elastic sealing block 403 of the sensor module 4, and the elastic sealing block 403 is mounted in the positioning groove 103 in a pressed manner in the axial direction, ensuring stable transmission of current. The outer peripheral wall of the elastic sealing block 403 is provided with an annular protrusion, and when the elastic sealing block 403 is assembled in the positioning groove 103, the annular protrusion (equivalent to an O-ring) blocks the space where the spring pin 201 is communicated with the outside, so that the waterproof effect is achieved.
The main housing 109 may have a notch 106 near the outer edge of the power supply housing 107, the main housing 109 engaging the lip 301 of the upper cover 3. The bottom lid 1 is centrally provided with a central aperture 105, the central aperture 105 matching a central wall 302 (described in detail below) of the top lid 3, the central wall 302 extending into the central aperture 105.

The power supply 207 occupies a space between the inner circumferential wall and the outer circumferential wall of the circuit board 204, and projects radially inward of the inner circumferential wall and radially outward of the outer circumferential wall of the circuit board 204.
In other embodiments, the upper cover 3, the bottom cover 1 and the circuit board 204 may be integrally formed by a low-temperature injection molding process.
