Description

Continuous analyte monitoring system

Technical Field

The present application relates to the field of medical device technology, and more particularly, to a continuous analyte monitoring system.

Background

Some physiological diseases, which have long disease duration and prolonged disease duration, require real-time monitoring of certain physiological parameters of the host to better track the treatment. Such as diabetes, require real-time monitoring of the host's blood glucose. Accurate blood sugar self-monitoring is the key to realizing good blood sugar control, is beneficial to evaluating the degree of glucose metabolism disorder of diabetics, formulating a blood sugar reduction scheme, and simultaneously reflecting the blood sugar reduction treatment effect and guiding the adjustment of the treatment scheme.

Currently, most commercially available instruments refer to blood glucose meters, and patients need to collect finger peripheral blood by themselves to measure the blood glucose level at that moment. However, this method has the following drawbacks: 1. the blood glucose level change between two measurements cannot be known, and the peak value and the valley value of the blood glucose can be missed by a patient, so that complications are caused, and the patient is irreversibly injured; 2. the finger tip puncture blood sampling for many times every day causes great pain for the diabetic. In order to overcome the above drawbacks, it is desirable to provide a method for continuously monitoring blood sugar of a patient, which is convenient for the patient to know the blood sugar status of the patient in real time and take measures in time, thereby effectively controlling the state of an illness and preventing complications to achieve a high quality of life.

In order to meet the requirements, technical personnel develop a monitoring technology capable of being implanted into subcutaneous tissues to continuously monitor subcutaneous blood sugar, the technology is characterized in that a sensor electrode is inserted into the subcutaneous tissues, the sensor electrode generates an oxidation reaction between interstitial fluid of a patient and glucose in a body, an electric signal is formed when the oxidation reaction is carried out, the electric signal is converted into a blood sugar reading through electronic equipment, the blood sugar reading is transmitted to a wireless receiver every 1 to 5 minutes, corresponding blood sugar data are displayed on the wireless receiver, and a map is formed and is provided for the patient and a doctor to refer to.

A continuous analyte monitoring system, such as blood glucose monitoring, includes a sensor assembly including a sensor electrode and electronics. The electronic equipment comprises a power supply, the electronic equipment and the sensor assembly are powered by the power supply, and if the power supply continuously supplies power to the electronic equipment and the sensor assembly in a non-working time, the service life of the electronic equipment is easily shortened. To solve the problem of continuous power supply during non-operation time, for example, chinese invention patent CN109310372B discloses an analyte sensor, which is configured to disconnect a battery from a Printed Circuit Board (PCBA) by providing a removable pull tab to prevent battery consumption during transportation and storage, wherein the pull tab can be removed by a user after inserting the sensor into the body of the user. Although this method can solve the problem of continuous power supply from the power supply during non-working time, the operation is cumbersome, and the tab is prone to shift due to jolt vibration during transportation and storage, which severely leads to the tab shifting completely from between the battery and the PCBA, which in turn leads to the tab losing its insulating effect on the battery and the PCBA. If chinese utility model patent CN209529134U discloses a developments blood glucose meter based on automatic control switch, through set up the switch circuit who has the tongue tube in the transmitter, when magnet is close to the transmitter, the tongue tube action to make the switch circuit disconnection, and then make being connected of transmitter disconnection and power. In the method, the reed switch is still a power-consuming component, so that the power consumption possibility still exists after long-term use, and meanwhile, the reed switch is accidentally powered off when the power off is not expected due to the stability, for example, a magnetic field exists around the reed switch, so that the monitoring is interrupted, and the use of a user is further influenced.

In addition, the electronic device of the existing continuous analyte monitoring system needs to be discarded after being used for a certain number of times, and in order to prevent the electronic device from being used continuously after meeting the discarding condition, the currently and commonly adopted method is to record the number of times of using the electronic device through software and give a prompt at a wireless receiver when the electronic device meets the discarding condition, but the electronic device cannot be stopped from being used continuously from the root.

Referring to fig. 1, 3, 4 and 5, the electronic device 400 is detachably mounted to the sensor assembly 200, for example, the electronic device 400 and the sensor assembly 200 may be fixed by a snap connection. The electronic device 400 includes a device housing 410 and an electronic circuit board 420 enclosed within the device housing 410, the electronic circuit board 420 having a number of electronic components integrated thereon.

The edge of the device case 410 is provided with locking heads 430 equal to the number of the locking latches 223, and the locking heads 430 pass through the locking holes 224 to be locked in cooperation with the locking latches 223. Two buckling parts 225 are arranged on two side edges of the sensor base 220 in a mirror symmetry manner, the buckling parts 225 comprise upright posts 226 which are formed on the edges of the sensor base 220 and extend upwards, clamping grooves 227 are formed on the inner surfaces of the upright posts 226, one ends of the clamping grooves 227 far away from the lock catches 223 are closed, tongue pieces 440 which are equal to the buckling parts 225 in number are formed on the edges of the equipment shell 410, the tongue pieces 440 are arranged to be matched and clamped into the clamping grooves 227 in a sliding manner, and the tongue pieces 440 are limited in the clamping grooves 227 by closing the ends of the clamping grooves 227 far away from the lock catches 223. The edge of the device housing 410 is formed with a second recess 450 for receiving the tongue 440, and when the tongue 440 is located in the second recess 450, the outer edge of the upright 226 forms a complete and smooth arc with the edge of the electronic device 400, thereby ensuring the integrity of the appearance of the device housing 410. Also, in one embodiment, the upper surface of the post 226 is coplanar with the upper surface of the device housing 410, thereby ensuring the integrity of the entirety of the coupling of the sensor mount 220 to the device housing 410. To facilitate the toggling of the latch 223, the upper surface of the latch 223 is not lower than the upper surface of the electronic device 400.

When the sensor base 220 is installed on the device housing 410, the latch 223 is opened by rotating, then the tongue piece 440 of the device housing 410 is clamped into the clamping groove 227 in a sliding manner, and then the latch 223 is rotated until the lock hole 224 is fastened on the lock head 430. When it is desired to separate the sensor mount 220 from the device housing 410, the latch 223 is simply rotated open and the tongue 440 is withdrawn from the slot 227 against the installation direction.

Referring to fig. 1, 9 and 10, a first conductive part 240 is disposed on the sensor assembly 200, a second conductive part 460 and a third conductive part 470 are disposed on the electronic device 400, the second conductive part 460 and the third conductive part 470 are insulated from each other, when the electronic device 400 is mounted on the sensor assembly 200, the first conductive part 240 is in electrical contact with the second conductive part 460 and the third conductive part 470, respectively, so that the second conductive part 460 and the third conductive part 470 are conducted by the first conductive part 240, and the second conductive part 460 and the third conductive part 470 are connected in series in a path for supplying power to the electronic circuit board 420, that is, when the second conductive part 460 and the third conductive part 470 are conducted by the first conductive part 240, power is allowed to be supplied to the electronic components on the electronic circuit board 420.

Generally, the electronic apparatus 400 is configured to be reusable, and as the number of uses of the electronic apparatus 400 increases, the endurance and accuracy thereof are affected, and thus, after the electronic apparatus 400 is used a certain number of times, the electronic apparatus 400 needs to be discarded or scrapped. With the present application, each time the sensor assembly 200 is replaced, as the electronic device 400 is detached from the sensor assembly 200, portions of the second conductive portion 460 and the third conductive portion 470 are removed; when the second conductive part 460 and the third conductive part 470 are all removed, the electronic apparatus 400 meets the scrapping condition, and at this time, the electronic apparatus 400 does not have the remaining second conductive part 460 and the remaining third conductive part 470, so that even if the electronic apparatus 400 is mounted on a new sensor assembly 200, the electronic apparatus 400 cannot normally operate, and the electronic apparatus 400 is prevented from being used after meeting the scrapping requirement.

In one embodiment, portions of the second conductive portion 460 and the third conductive portion 470 are removed by the first conductive portion 240. In other embodiments, portions of the second and third

conductive portions

460, 470 are removed by other components disposed on the sensor assembly 200.

Referring to fig. 1, fig. 11 and fig. 12, in an embodiment, the second conductive portion 460 may include a plurality of first conductive members 461 stacked along the removing direction, the third conductive portion 470 may include a plurality of second conductive members 471 stacked along the removing direction, the number of the first conductive members 461 is the same as the number of the second conductive members 471, wherein each of the first conductive members 461 is separable, and each of the second conductive members 471 is separable. When the sensor assembly 200 is replaced each time, as the electronic device 400 is detached from the sensor assembly 200, since the plurality of first conductive members 461 are stacked along the removing direction, the plurality of second conductive members 471 are stacked along the removing direction, the first conductive portion 240 is disposed at one side of the second conductive portion 460 and the third conductive portion 470, the relative position relationship between the plurality of first conductive members 461, the plurality of second conductive members 471 and the first conductive portion 240 is determinable, and the portions of the second conductive portion 460 and the third conductive portion 470 can be removed by the first conductive portion 240, so that the positions of the first conductive member 461 closest to the first conductive portion 240 and the second conductive member 471 closest to the first conductive portion 240 can be uniquely determined. The first conductive member 461 closest to the first conductive portion 240 and the second conductive member 471 closest to the first conductive portion 240 are simultaneously removed by the first conductive portion 240, and then the remaining first conductive member 461 is automatically moved by a distance of the first conductive member 461 along the removing direction to fill in the position of the removed first conductive member 461; likewise, the remaining second conductive member 471 is automatically moved a distance of the second conductive member 471 in the removing direction to fill the position of the removed second conductive member 471. The first conductive member 461 and the second conductive member 471 are added to make electrical contact with the first conductive portion 240 on the new sensor assembly 200. When the first and second

conductive members

461 and 471 are all removed, the electronic device 400 cannot be used continuously, and therefore, the present application may limit the number of times the electronic device 400 is used by setting the number of the first and second

conductive members

461 and 471. For example, if 5 first conductive members 461 and 5 second conductive members 471 are provided, the electronic device 400 cannot be used any more after being reused 5 times. In one embodiment, the first conductive member 461 and the second conductive member 471 are electrically connected to the first conductive portion at a specific position. In another embodiment, the first conductive portion 240 is elastic and can be adaptively electrically connected to the first conductive member 461 and the second conductive member 471 after the partial structure is removed.

Referring to fig. 5 and 6, in an embodiment, the electronic device 400 further includes an elastic restoring mechanism 480, and the elastic restoring mechanism 480 is configured to drive the remaining first conductive member 461 and the remaining second conductive member 471 in the removing direction. The elastic return mechanism 480 includes a return spring 481 that is pre-compressed and a drive seat 482 arranged at a free end of the return spring 481, the free end of the return spring 481 driving the drive seat 482 in the removal direction; one end of the driving seat 482 is fixed to a free end of the return spring 481, and the other end abuts on the first conductive member 461 closest to the driving seat 482 and the second conductive member 471 closest to the driving seat 482.

With continued reference to fig. 5 and 6, in one embodiment, a cavity 490 is formed in the device housing 410 for accommodating the elastic return mechanism 480, the first conductive portion 240, and the second conductive portion 460. The cavity 490 extends to the outer surface of the device case 410 along the removal direction and forms an opening 491 for the first conductive portion 240 and the second conductive portion 460 to pass through on the outer surface of the device case 410.

In one embodiment, the first conductive member 461 and the second conductive member 471 are arranged in mirror symmetry. For example, the first conductive member 461 and the second conductive member 471 are semi-annular, correspondingly, the first conductive portion 240 is annular, the first conductive member 461 and the second conductive member 471 fall on the first conductive portion 240 along the projection of the removal direction, the cavity 490 in the device housing 410 is a cylindrical cavity corresponding to the outer contour of the first conductive member 461 and the second conductive member 471, a guiding column 492 is formed in the cavity 490 along the axial direction of the cavity 490, the guiding column 492 is located between the first conductive member 461 and the second conductive member 471, and the outer diameter of the guiding column 492 corresponds to the inner contour of the first conductive member 461 and the second conductive member 471, the first conductive member 461 and the second conductive member 471 are defined in the gap between the guiding column 492 and the cavity 490 by the cooperation between the outer surface of the guiding column 492 and the inner surface of the cavity 490, and the first conductive member 461 and the second conductive member 471 are prevented from shaking in the cavity 490 in the radial direction. Further, two guiding ribs 493 are formed on the guiding column 492, and the two guiding ribs 493 are respectively located in two joints between the first conductive member 461 and the second conductive member 471, so as to prevent the first conductive member 461 and the second conductive member 471 from moving circumferentially in the cavity 490. By the provision of the guide posts 492 and the guide ribs 493, it can be ensured that the first conductive member 461 and the second conductive member 471 move on a straight trajectory along the removal direction. In this embodiment, the corresponding driving seat 482 is also annular, the projection of the driving seat 482 along the removing direction falls on the first conductive portion 240, the driving seat 482 and the return spring 481 are sleeved on the guide post 492, and in one embodiment, the driving seat 482 may be made of insulating plastic.

Accordingly, a window 494 through which the third conductive member 462 and the fourth conductive member 472 protrude is formed on the inner wall of the cavity 490, and the third conductive member 462 and the fourth conductive member 472 are disposed at positions adjacent to the opening 491. In one embodiment, the third and fourth

conductive members

Referring to fig. 7 and 8, when the electronic device 400 is mounted on the sensor assembly 200, the first step 4612 presses the first elastic hook 241 to deform the first elastic hook, and the first elastic hook 241 is restored and hooks the first step 4612 after passing over the first step 4612; similarly, the second step 4712 presses and deforms the second elastic hook 242, and the second elastic hook 242 goes over the second step 4712 and then returns to its original shape to hook the second step 4712. Wherein, the first step 4612 and the second step 4712 may respectively include a protruding portion, and the first elastic hook 241 may hook the protruding portion. Referring to fig. 11 and 12, when the electronic apparatus 400 is detached from the sensor assembly 200, the first elastic hook portion 241 hooks the first step 4612, and the second elastic hook portion 242 hooks the second step 4712, so that the first conductive member 461 closest to the first conductive portion 240 and the second conductive member 471 closest to the first conductive portion 240 are removed when the electronic apparatus 400 is separated from the sensor assembly 200. The fixation of the third and fourth

conductive members

462, 472 to the first and second

conductive members

461, 471 is overcome during the removal of the electronic device 400 from the sensor assembly 200.

In an embodiment, the first conductive member 461 and the second conductive member 471 may be hollow structures, a lower surface of the first conductive member 461 is formed with a first slit 4613 allowing the first elastic hook 241 to pass through, a width of the first elastic hook 241 after being expanded is larger than a width of the first slit 4613, when the electronic device 400 is mounted on the sensor assembly 200, the first elastic hook 241 is embedded in the first slit 4613 and passes through the first slit 4613 to reach the inside of the first conductive member 461, the first elastic hook 241 is compressed and deformed by being pressed by an edge of the first slit 4613 during passing through the first slit 4613, and the first elastic hook 241 returns to an expanded state after passing through the first slit 4613, in this embodiment, the first step 4612 is a part of the edge of the first slit 4613. Similarly, the lower surface of the second conductive member 471 is formed with a second slit 4713 allowing the second elastic hook 242 to pass through, the width of the second elastic hook 242 after being opened is greater than the width of the second slit 4713, when the electronic device 400 is mounted on the sensor assembly 200, the second elastic hook 242 is embedded in the second slit 4713 and passes through the second slit 4713 to reach the inside of the second conductive member 471, the second elastic hook 242 is compressed and deformed by being pressed by the edge of the second slit 4713 during passing through the second slit 4713, and the second elastic hook 242 returns to the opened state after passing through the second slit 4713, in this embodiment, the second step 4712 is a part of the edge of the second slit 4713. The lower surface in this embodiment refers to a surface of the first conductive member 461 or the second conductive member 471 facing the first conductive part 240, and when the electronic device 400 is mounted on the sensor assembly 200, the lower surface of the first conductive member 461 and the lower surface of the second conductive member 471 are used for making electrical contact with the first conductive part 240.

By the cooperation of the hollow first conductive member 461 and the first elastic hook portion 241, the first conductive member 461 is left on the first conductive portion 240 and cannot be separated from the first elastic hook portion 241 on the first conductive portion 240 when the first conductive member 461 is removed from the first conductive portion 240, and the second conductive member 471 is left on the first conductive portion 240 and cannot be separated from the second elastic hook portion 242 on the first conductive portion 240 when the first conductive portion 240 is removed from the second conductive member 471. The first conductive part 240 with the first conductive member 461 and the second conductive member 471 cannot be engaged with the remaining first conductive member 461 and the remaining second conductive member 471 on the electronic device 400, so that the first conductive part 240 and the sensor assembly 200 cannot be reused, and at this time, the user can replace the sensor assembly 200 with a new one. Typically, the sensor assembly 200 has a service life of 14 days, and over 14 days, the sensor assembly 200 fails and is no longer in service. When replacement is required, the electronic apparatus (which can be used repeatedly for the same number of times as the number of the first conductive members 461) is taken out, and when replacement of the sensor assembly 200 is not required, the electronic apparatus is not taken out. When the electronic device also has the remaining first conductive member 461 and the remaining second conductive member 471, the electronic device can also be used in connection with a new sensor assembly 200 until the electronic device fails when the electronic device no longer has the remaining first conductive member 461 and the remaining second conductive member 471.
