Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to the technical field of an electrode magnetic connector for continuous glucose monitoring (CGM). BACKGROUND

[0002] With the continuous development of medical technology, continuous glucose monitoring (CGM) systems play an increasingly important role in diabetes management. A CGM system usually includes an implantable sensor and a detachable signal acquisition device, and a connector is a key component for connecting the sensor and the signal acquisition device, whose performance directly affects the reliability and user experience of the entire system.

[0003] At present, the common CGM connector on the market mainly adopts a traditional plug-in structure. This structure has multiple technical problems in actual application: first, the traditional plug-in connection requires a large plug-in force, and frequent plug-in operations can easily cause pin needles to bend and deform or wear, affecting the reliability of electrical connection and product service life; second, the positioning and installation method between the sensor and the connector is not accurate enough, which can easily cause poor contact between the sensor electrode and the pin needle, affecting accurate signal acquisition; third, the existing connector has insufficient protection performance and is easily eroded by sweat, moisture, etc. during daily use, reducing the use reliability of the product.

[0004] In addition, the existing connector structure is complex and the assembly process is cumbersome, which not only increases production costs but also easily causes quality fluctuations. In particular, in terms of circuit board welding connection, due to the lack of effective positioning structure, welding position deviation is easily caused, affecting product yield. At the same time, the traditional connector is easily detached when accidentally stressed or dropped, which is unacceptable in the use scenario of medical devices.

[0005] In addition, the existing connector generally has the problems of large size and insufficient compact structure, which is not conducive to the miniaturization and thinning development of the product. Moreover, the connector and the sensor often use complex fixing methods such as threads, which not only increases the operation difficulty of patients but also is not conducive to the rapid replacement and maintenance of medical devices.

[0006] Therefore, it is urgent to develop a new type of CGM electrode connector that can not only ensure the reliability of electrical connection but also simplify the operation process, while having good protection performance and service life, meeting the increasing miniaturization and portability requirements of medical devices.

[0073] Optionally, the first magnet 24 and the second magnet are both permanent magnets, the first magnet 24 is inlaid on the male seat 2, and the second magnet is inlaid on the female seat 3, and the first magnet 24 and the second magnet are oppositely arranged to form two pairs of magnetically attractive structures.

[0074] Optionally, the sensor base 1 and the male seat 2 are made of insulating materials.

[0075] Optionally, the outer surfaces of the male seat 2 and the female seat 3 are provided with waterproof sealing layers.

[0076] Specifically, as shown in the drawings, Figure 1 The embodiment provides a CGM electrode magnetic connector, which is used for realizing electrical connection between a CGM sensor and a signal acquisition circuit, and comprises a sensor base 1, a male seat 2, a female seat 3 and a circuit board 4.

[0077] The sensor base 1 is provided with a sunken mounting cavity 11, the depth of the mounting cavity 11 is matched with the height of a to-be-mounted sensor (not shown in the drawings), so that the electrodes of the sensor are located in the same plane as the first pin 21 on the male seat 2 after the sensor is mounted in place, so as to realize reliable electrical connection.

[0078] The male seat 2 is detachably connected with the sensor base 1 through a buckle structure. Specifically, the outer wall of the sensor base 1 is provided with a limiting step 12, and one end of the male seat 2 is provided with a buckle 22 matched with the limiting step 12. When the male seat 2 is sleeved on the sensor base 1, the buckle 22 is clamped with the limiting step 12, so that the male seat 2 is firmly fixed on the sensor base 1. When disassembly is needed, the buckle 22 can be removed from the limiting step 12, and the operation is very convenient.

[0079] The male seat 2 is internally provided with the first pin 21, the first pin 21 is made of conductive metal material, and the top of the first pin 21 is provided with an elastic structure. When the sensor is mounted in place, the elastic structure of the first pin 21 abuts against the surface of the sensor electrode, so that the first pin 21 reliably contacts with the sensor electrode, and a stable signal transmission path is established. Meanwhile, the male seat 2 is also provided with a first avoiding groove for accommodating the first pin 21, so as to avoid that the first pin 21 is exposed and bent by accident in a non-working state.

[0080] The female seat 3 is electrically connected with the circuit board 4 and detachably connected with the male seat 2 by magnetic force. The female seat 3 is internally provided with a second pin 31 in contact with the first pin 21, which is also made of conductive metal material and has an L-shaped bend structure at the head, and the other end is electrically connected with the circuit board 4 by welding. The female seat 3 is symmetrically provided with two welding columns 33, which are respectively and accurately matched with the corresponding positioning holes 41 on the circuit board 4 and are welded and fixed, which not only provides an accurate positioning reference, but also enhances the connection strength. Similarly, the female seat 3 is also provided with a second avoiding slot to accommodate the second pin 31 to avoid damage.

[0081] The opposite sides of the male seat 2 and the female seat 3 are respectively inlaid with two pairs of first magnets 24 and second magnets, both of which are permanent magnets. When the male seat 2 and the female seat 3 are connected in position, the two pairs of magnets form a magnetic attraction structure to ensure that the male seat 2 and the female seat 3 can be quickly positioned and closely fitted, and at the same time provide sufficient anti-falling performance. When it is necessary to disassemble the connector, only a proper separating force needs to be applied, which is convenient to operate.

[0082] Considering the use environment of the connector, the sensor base 1 and the male seat 2 are made of insulating materials, and the outer surfaces of the female seat 3 and the male seat 2 are also provided with a waterproof sealing layer to adapt to various harsh working conditions.

[0083] Through the above structure design, the CGM electrode magnetic connector of the embodiment realizes accurate positioning and installation of the sensor, convenient connection of the male seat and the female seat, reliable transmission of the electrical signal and good environmental adaptability, and is particularly suitable for application in the field of medical instruments.

[0084] More specifically, the elastic structure refers to a structure with elastic deformation ability arranged at the top of the first pin 21. It can be a spring, a section of elastic metal sheet or any other structure with elasticity.

[0085] When the male seat 2 is connected with the sensor base 1, the elastic structure of the first pin 21 will contact the electrode of the sensor. Since there may be a certain tolerance in the installation position of the sensor, the height of the sensor electrode is not completely consistent. The elastic structure can well solve this problem.

[0086] Specifically, when the height of the sensor electrode is slightly lower than the height of the first pin 21, the elastic structure will deform during the contact between the first pin 21 and the sensor electrode, generating a downward pressing force, so that the end of the first pin 21 can tightly adhere to the surface of the sensor electrode, ensuring stable and reliable electrical contact between the two.

[0087] Conversely, when the height of the sensor electrode is slightly higher than that of the first pin 21, the elastic structure can also be deformed, so that the end of the first pin 21 always maintains contact with the sensor electrode, avoiding the problem of poor contact caused by height difference.

[0088] This design of using an elastic structure to compensate for installation errors not only simplifies the installation process and reduces the processing precision requirement, but also greatly improves the applicability and reliability of the connector, which is a major innovation of the utility model.

[0089] In addition, the elastic structure can also play a buffering and protection role when the two components are separated. When the male seat 2 is separated from the sensor base 1, the elastic structure will gradually return to the original state, making the separation process between the first pin 21 and the sensor electrode more stable, avoiding the impact and wear caused by instantaneous elastic opening, and prolonging the service life of the connector.

[0090] In summary, the elastic structure on the first pin 21 plays a crucial role in sensor installation, electrical connection establishment, and component separation through its unique elastic deformation capability, which is a delicate and innovative design in the utility model.

[0091] Further, the first avoiding groove is arranged on the male seat 2 and is used for accommodating the first pin 21. Specifically, the bottom of the first pin 21 is located in the first avoiding groove, and the elastic structure 211 at the top is exposed outside the first avoiding groove. In this way, in the state that the male seat 2 is separated from the sensor base 1, the first pin 21 is completely accommodated in the first avoiding groove and cannot be exposed.

[0092] Similarly to the first avoiding groove, the second avoiding groove is arranged on the female seat 3 and is used for accommodating the second pin 31. The second pin 31 is different from the first pin 21, which is a bend structure, so the shape of the second avoiding groove is slightly different from that of the first avoiding groove and needs to be adapted to the curved shape of the second pin 31. One end of the second pin 31 is located in the second avoiding groove, and the other end is exposed outside the second avoiding groove and is welded with the circuit board 4.

[0093] The purposes of arranging the first avoiding groove and the second avoiding groove are as follows:

[0094] Protection: When the connector is in a separated state, the first pin 21 and the second pin 31 are completely located in the avoiding groove and cannot be exposed. In this way, the pin can be effectively prevented from being accidentally touched, bent or damaged, improving the safety and reliability of the connector.

[0095] Positioning effect: the inner wall of the avoidance groove can play the role of positioning the pin needle. The first pin needle 21 and the second pin needle 31 will not deviate or shake in the avoidance groove, thereby ensuring their position accuracy and laying a foundation for subsequent connection.

[0096] Insulating effect: since the avoidance groove is located inside the male seat 2 and the female seat 3, which are made of insulating materials, the avoidance groove also plays a certain insulating effect, which can prevent short circuit or electric leakage between the pin needle and the shell, and improve the electrical safety performance of the connector.

[0097] Reducing volume: accommodating the pin needle in the avoidance groove can reduce the overall height and volume of the connector, which is very beneficial for some application scenarios that have strict requirements on volume, such as wearable devices.

[0098] In summary, the first avoidance groove and the second avoidance groove protect, position, insulate the first pin needle 21 and the second pin needle 31, and reduce the overall volume of the connector, which not only ensures the performance and reliability of the connector, but also makes the structure of the connector more compact and reasonable, which is another big innovation point in the utility model.

[0099] Working principle:

[0100] Firstly, the sensor to be measured is installed in the sunken mounting cavity 11 of the sensor base 1, so that the sensor electrode and the first pin needle 21 on the male seat 2 are located in the same plane. Since the depth of the mounting cavity 11 matches the height of the sensor, the sensor can be accurately fixed on the base 1, laying a foundation for subsequent electrical connection.

[0101] Then, the male seat 2 and the sensor base 1 are connected through the buckle structure. The buckle 22 on the male seat 2 cooperates with the limiting step 12 on the base 1, and only needs to push the male seat 2 downward along the outer wall of the base 1 until the buckle 22 is buckled into the groove of the limiting step 12, and then the male seat 2 is firmly fixed on the base 1. This buckle type connection method is simple to operate and can provide reliable fixing effect.

[0102] Next, while the male seat 2 and the sensor base 1 are mechanically connected, the first pin needle 21 on the male seat 2 also realizes electrical connection with the electrode of the sensor. The first pin needle 21 is provided with an elastic structure, which will deform when it contacts the sensor electrode, thereby generating a compression force to keep the first pin needle 21 and the sensor electrode in stable and reliable contact, establishing the first electrical signal transmission path between the sensor and the connector.

[0103] Finally, the female seat 3 is welded with the circuit board 4, and then is detachably connected with the male seat 2 through magnetic force. The second pin needle 31 on the female seat 3 is in a bent structure, one end of which is in contact with the first pin needle 21, and the other end is welded with the circuit board 4 through the welding column 32, so that a second electrical signal transmission path is established between the connector and the circuit board. It is worth mentioning that the positioning column 33 on the female seat 3 plays a role in accurate positioning during the welding process, greatly improving the assembly efficiency. When the female seat 3 is connected with the male seat 2, the first magnet 24 and the second magnet 35 generate magnetic force to attract the two components to tightly adhere to each other, and at the same time, the first pin needle 21 and the second pin needle 31 are stably in contact, ensuring the reliability of the entire electrical connection.

[0104] In summary, the sensor establishes a stable and reliable electrical signal transmission path with the circuit board 4 through the mechanical connection and electrical connection between the sensor base 1, the male seat 2, the female seat 3 and the circuit board 4. When the sensor needs to be replaced, the male seat 2 is simply removed from the sensor base 1, and then the female seat 3 is separated from the male seat 2, which is very convenient. At the same time, since the first pin needle 21 and the second pin needle 31 inside the connector are respectively accommodated in the first and second avoiding grooves, they will not be accidentally bent or damaged during installation and disassembly, greatly improving the service life of the connector.

[0105] The advantages of the above embodiment are as follows:

[0106] The sensor base adopts a sunken mounting cavity, which is compatible with the height of the sensor, so that the electrode of the sensor and the first pin needle are located in the same plane, which is conducive to realizing stable and reliable electrical connection.

The second pin needle of the female seat adopts a bent structure and is welded on the circuit board, which is conducive to saving layout space.
