Description

Technical Field

[0001] This utility model relates to the field of blood glucose monitoring technology, and in particular to a blood glucose monitoring device. Background Technology

[0002] Blood glucose monitoring is the regular checking of blood glucose levels. Implementing blood glucose monitoring allows for better control of blood glucose fluctuations in diabetic patients, providing important guidance for lifestyle, activity, exercise, diet, and rational medication use. It can also help patients detect problems early and seek medical attention promptly.

[0003] Blood glucose monitoring devices are generally used by diabetic patients to monitor their blood glucose levels, thus understanding their blood sugar status. This is of great significance for diabetic patients and some high-risk groups. Continuous glucose monitoring (CGM) devices are one type of blood glucose monitoring device. Currently, CGM devices are generally non-removable; they are discarded once the battery is depleted. Thus, even if other components have not reached the end of their lifespan, they must be discarded along with the device, resulting in waste.

[0004] To reduce costs and avoid waste, existing technologies include separate or detachable continuous glucose monitoring (CGM) devices. However, since CGM devices must remain attached to the user throughout use, separate designs inevitably allow water, sweat, or other liquids to enter the device, potentially causing short circuits and affecting its lifespan. Furthermore, separate designs require consideration of assembly; excessively tight fitting of the carriers solely for sealing can lead to inconvenience for users, making assembly and disassembly counterproductive.

[0005] Therefore, it is necessary to design a blood glucose monitoring device that not only meets the requirements of sealing and waterproofing, but also allows users to easily assemble, disassemble, and use it. Utility Model Content

[0006] In order to overcome the technical problem that traditional blood glucose monitoring devices described above cannot simultaneously achieve both ease of use and waterproof sealing performance, this utility model provides a blood glucose monitoring device.

[0007] The technical solution adopted by this utility model to solve its problem is:

[0008] A blood glucose monitoring device, comprising:

[0009] A sensor carrier includes a first housing and a probe module and a sensor module located in the middle of the first housing and electrically connected to each other. The first housing has a first buckle and a second slot located on the opposite side of the first buckle. The first buckle is an elastic structure. The probe module includes a second housing, and the sensor module includes a third housing.

[0010] The launch carrier includes a fourth housing and a launch module located in the middle of the fourth housing. The periphery of the fourth housing is provided with a first slot corresponding to the first buckle and a second buckle corresponding to the second slot.

[0011] The first housing is sealed to the second housing and the third housing respectively; when the sensor carrier and the transmitting carrier cooperate with each other, the sensor module and the transmitting module are electrically connected, the first buckle and the first slot are engaged, and the second buckle and the second slot are engaged.

[0012] Furthermore, the number of the second buckle and the second slot is greater than or equal to two; the first buckle protrudes outward toward the side away from the first housing to form a flange structure.

[0013] Furthermore, the first housing is provided with at least one third slot on its periphery, and the fourth housing is provided with at least one third buckle corresponding to the third slot on its periphery; when the sensor carrier and the transmitting carrier cooperate with each other, the third buckle and the third slot engage.

[0014] Furthermore, the first housing and the second housing, and the first housing and the third housing are sealed together by adhesive.

[0015] In a preferred embodiment, the probe module includes a probe, one end of which is disposed corresponding to the second housing, and the other end of which extends outward toward the side away from the first housing.

[0016] Furthermore, the sensor module includes a sensor circuit board and a connector. The sensor circuit board is provided with conductive spring pins. One end of the connector is connected to the sensor circuit board, and the other end is connected to the probe.

[0017] In another preferred embodiment, the transmitting module further includes a transmitter circuit board having contacts; the interior of the fourth housing is provided with a waterproof filler for sealing the transmitter circuit board within the fourth housing.

[0018] Furthermore, the waterproof filler is provided with a first annular rib, which is located on the outer periphery of the contact point.

[0019] Furthermore, the launch carrier also includes a power module located in the middle of the fourth housing, and the waterproof filler is provided with a second annular rib, which is located on the outer periphery of the power module.

[0020] Furthermore, a patch is provided on the side of the sensor carrier away from the transmitting carrier.

[0021] In summary, the blood glucose monitoring device provided by this utility model has at least the following technical advantages compared with the prior art:

[0022] 1) The sensor carrier of this utility model includes a first housing, with a first buckle and a second slot on the opposite side of the first buckle on the outer periphery of the first housing; the transmitting carrier includes a fourth housing, with a first slot and a second buckle on the opposite side of the first slot on the outer periphery of the fourth housing. When assembling the sensor carrier and the transmitting carrier, align the second buckle with the second slot, push the transmitting carrier obliquely to engage the second buckle in the second slot, and then press down on the transmitting carrier to engage the elastic first buckle in the first slot. At this time, the blood glucose monitoring device is in the loaded state. When disassembling the sensor carrier and the transmitting carrier, pry the elastic first buckle outwards to separate the first buckle from the first slot, the second buckle from the second slot, and then remove the transmitting carrier. At this time, the blood glucose monitoring device is in the unloaded state. The above structural design is simple and reasonable, and the assembly and disassembly operations are convenient.

Therefore, they should not be construed as limitations on this utility model.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] Example 1

[0042] In the first embodiment of this utility model, a technical solution is provided on how to achieve the assembly, disassembly and use of the sensor carrier 1 and the transmitting carrier 2, as well as good sealing performance.

[0043] See Figures 1-3 As shown, according to an embodiment of the present invention, the blood glucose monitoring device includes a sensor carrier 1 and a transmitter carrier 2. When the sensor carrier 1 and the transmitter carrier 2 are connected, the blood glucose monitoring device is in a loaded state; when the sensor carrier 1 and the transmitter carrier 2 are disassembled, the blood glucose monitoring device is in an unloaded state.

[0044] The specific structural designs of sensor carrier 1 and transmitting carrier 2 are as follows:

[0045] See Figures 4-6 As shown, the sensor carrier 1 includes a first housing 11, a probe module 12 and a sensor module 13. The periphery of the first housing 11 is provided with a first buckle 111 and a second slot 112, and the second slot 112 is located on the opposite side of the first buckle 111. The first buckle 111 is an elastic structure.

[0046] The probe module 12 and the sensor module 13 are located in the middle of the first housing 11. The probe module 12 includes a second housing 121, and the sensor module 13 includes a third housing 131. The first housing 11 is sealed to the second housing 121 and the third housing 131, respectively. That is, the first housing 11 and the second housing 121, and the first housing 11 and the third housing 131 are sealed to each other, which enhances the sealing performance between them and prevents water, sweat, etc. from entering the second housing 121 and the third housing 131 during use. This improves the waterproof performance of the internal structure of the probe module 12 and the sensor module 13 and extends the service life of the blood glucose monitoring device.

[0047] See Figure 7 and Figure 8 As shown, the launch carrier 2 includes a fourth housing 21 and a launch module 22. The fourth housing 21 is provided with a first slot 211 and a second buckle 212 on its periphery. The first slot 211 is corresponding to the first buckle 111 of the first housing 11, and the second buckle 212 is corresponding to the second slot 112 of the first housing 11. The launch module 22 is located in the middle of the fourth housing 21.

[0048] Based on the above structural design, the usage process and working principle of the blood glucose monitoring device of this utility model are as follows:

[0049] See Figure 3 As shown, when assembling the sensor carrier 1 and the transmitter carrier 2, the second buckle 212 of the fourth housing 21 is aligned with the second slot 112 of the first housing 11. The transmitter carrier 2 is pushed obliquely so that the second buckle 212 is inserted into the second slot. Then the transmitter carrier 2 is pressed down so that the elastic first buckle 111 is deformed outward and then returns to its shape, thereby being inserted into the first slot 211 of the fourth housing 21. At this time, the sensor carrier 1 and the transmitter carrier 2 are connected, and the blood glucose monitoring device is in the loading state.

[0050] See Figure 3 As shown, similarly, when disassembling the sensor carrier 1 and the transmitter carrier 2, the elastic first buckle 111 is pried outward, and the transmitter carrier 2 is pulled upward, so that the first buckle 111 and the first slot 211, the second buckle 212 and the second slot 112 are separated respectively, and then the transmitter carrier 2 can be taken out. At this time, the sensor carrier 1 and the transmitter carrier 2 are disassembled and separated, and the blood glucose monitoring device is switched to the unloading state.

[0051] Therefore, the above structural design is simple and reasonable, and the assembly and disassembly operations are convenient. While meeting the requirements of sealing and waterproof performance, it also facilitates the user's assembly, disassembly and use of the blood glucose monitoring device.

[0052] More specifically, when the blood glucose monitoring device is in the loaded state, the sensor module 13 of the sensor carrier 1 and the transmitter module 22 of the transmitter carrier 2 are electrically connected, forming an electrical circuit by connecting the probe module 12, the sensor module 13, and the transmitter module 22. The transmitter module 22 transmits the data detected by the probe module 12 to an external device, thereby monitoring the user's blood glucose. After one use, the blood glucose monitoring device is removed from the user, the sensor carrier 1 and the transmitter carrier 2 are disassembled and separated, the sensor carrier 1 is removed and discarded, and a new sensor carrier 1 is used to replace the transmitter carrier 2, thus reusing the transmitter carrier 2 and avoiding waste.

[0053] Optionally, see Figures 4-6As shown, the number of second buckles 212 and second slots 112 is greater than or equal to two, and preferably two, to improve the connection stability of the first housing 11 and the fourth housing 21 at this position.

[0054] Optionally, see Figures 4-6 As shown, the first latch 111 protrudes outward toward the side away from the first housing 11 to form a flange structure 114. This flange structure 114 is used by the user to pry open the first latch 111 with their fingers, thereby separating the first latch 111 from the first slot 211, facilitating the disassembly of the sensor carrier 1 and the transmitting carrier 2. Preferably, the flange structure 14 is inclined upward toward the outside, making it convenient for the user to press and pry open the first latch 111 with their fingers.

[0055] See Figures 4-6 As shown, in a preferred embodiment, the first housing 11 is further provided with at least one third slot 113 on its periphery, and the fourth housing 21 is further provided with at least one third buckle 213 corresponding to the third slot 113 on its periphery. Specifically, when the sensor carrier 1 and the transmitting carrier 2 cooperate with each other, the third buckle 213 and the third slot 113 engage.

[0056] Preferably, the third slot 113 is located on the periphery of the first housing 11 on the side other than the first buckle 111 and the second slot 112, and the third buckle 213 is located on the periphery of the fourth housing 21 on the side other than the first slot 211 and the second buckle 212, so that it can connect all the periphery positions of the four sides of the first housing 11 and the fourth housing 21 by combining with the combination of the first buckle 111 and the first slot, and the combination of the second slot 112 and the second buckle 212.

[0057] Preferably, the number of third slots 113 and third buckles 213 is set to two, and the two third slots 113 and the two third buckles 213 are respectively arranged on opposite sides of each other, which further improves the connection stability of the first housing 11 and the fourth housing 21.

[0058] In another preferred embodiment, the first housing 11 and the second housing 121, and the first housing 11 and the third housing 131 are sealed together by adhesive, preferably by applying UV adhesive to prevent water, sweat, etc. from entering the second housing 121 and the third housing 131 during use, thereby improving the waterproof performance of the probe module 12 and the sensor module 13 and extending the service life of the blood glucose monitoring device.

[0059] Preferably, the sensor carrier 1 is provided with an adhesive patch 4 on the side away from the transmitting carrier 2, which is used to attach the sensor carrier 1 to the user's body.

[0060] Example 2

[0061] In the second embodiment of this utility model, a specific structural design scheme for the sensor carrier 1 is provided.

[0062] See Figures 3-6 As shown, in the technical solution of this embodiment, the probe module 12 includes a probe 122. One end of the probe 122 is correspondingly disposed with respect to the second housing 121, so that the second housing 121 can provide a sealing and waterproof protection for the area where the probe 122 is located. The other end of the probe 122 extends outward toward the side away from the first housing 11, and is used to pierce the user's arm or other parts when using the blood glucose monitoring device to detect the user's blood glucose.

[0063] See Figure 6 As shown, in a preferred embodiment, the sensor module 13 includes a sensor circuit board 132 and a connector 133. The sensor circuit board 132 is provided with a conductive spring pin 134. One end of the connector 233 is connected to the sensor circuit board 132, and the other end of the connector 233 is connected to the probe 122. The conductive spring pin 134 is used to connect to the transmitting module 22 of the transmitting carrier 2 (specifically, to connect to the contact 222 described in the following embodiments), enabling the sensor carrier 1 and the transmitting carrier 2 to conduct electricity and realize data transmission between them.

[0064] Preferably, the conductive spring needle 134 is formed by a combination of a needle head, a spring, a needle tube, and a needle tail, and is used to form an electrical contact with the launching module 22.

[0065] In this embodiment, when using the blood glucose monitoring device, the probe 122 is inserted into the user's arm or other part of the body to detect the user's blood glucose level. The obtained data is input to the transmitting module 22 through the connector 133, sensor circuit board 132, and conductive spring 134. The transmitting module 22 then sends the acquired data to an external device. During the user's use of this blood glucose monitoring device, the probe module 12 detects the user's blood glucose level multiple times, and the transmitting module 22 continuously transmits the obtained data to the external device, thereby continuously and dynamically monitoring the user's blood glucose parameters.

[0066] Example 3

[0067] In the third embodiment of this utility model, a specific structural design scheme for the launch carrier 2 is provided.

[0068] See Figure 7 and Figure 8As shown, in the technical solution of this embodiment, the transmitting module 22 further includes a transmitter circuit board 221. The transmitter circuit board 221 is provided with a contact 222, which is used to form an electrical contact with the conductive spring pin 134 on the sensor circuit board 132 described in the above embodiment, so as to make the sensor carrier 1 and the transmitting carrier 2 conductive and realize data transmission between the two.

[0069] More specifically, the interior of the fourth housing 21 is provided with a waterproof filler 3, which is used to seal the transmitter circuit board 221 inside the fourth housing 21, thereby ensuring that water or sweat cannot enter the exposed areas of the transmitter circuit board 221.

[0070] Preferably, the waterproof filler 3 is made of silicone. Liquid silicone can be filled into the fourth housing 21 by heating and pouring during manufacturing and then cooled and fixed, thereby reducing gaps and improving the sealing performance of the transmitter circuit board 221 in the fourth housing 21.

[0071] See Figure 7 As shown, in a preferred embodiment, the waterproof filler 3 is provided with a first annular rib 31, which is located on the outer periphery of the contact 222. When the sensor carrier 1 and the transmitting carrier 2 are connected, i.e., when the blood glucose monitoring device is in the loaded state, the first annular rib 31 is compressed and abuts against the first housing 11, ensuring that water or sweat cannot enter the area where the contact 222 is located, improving the contact safety between the conductive spring needle 134 and the contact 222, and further improving the sealing performance of the transmitting carrier 2.

[0072] See Figure 7 As shown, in another preferred embodiment, the launch carrier 2 further includes a power module 23, which is located in the middle of the fourth housing 21 and is used to provide power to the launch module 22, sensor module 13, probe module 12, etc.

[0073] Specifically, the waterproof filler 3 is also provided with a second annular rib 32, which is located on the outer periphery of the power module 23. When the sensor carrier 1 and the transmitting carrier 2 are connected, that is, when the blood glucose monitoring device is in the loading state, the second annular rib 32 is compressed and abuts against the first housing 11, ensuring that water or sweat cannot enter the area where the power module 23 is located, preventing short circuits, and further improving the sealing performance of the transmitting carrier 2.

[0074] Preferably, the first annular rib 31 and the second annular rib 32 are both annular protrusions that protrude in a direction away from the fourth housing 21.

[0075] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
