Description

Technical Field

[0001] This invention relates primarily to the field of medical devices, and in particular to a body fluid analyzer detection device. Background Technology

[0002] In a healthy person, the pancreas automatically monitors blood glucose levels and secretes the necessary insulin / glucagon. However, in diabetic patients, the pancreas malfunctions and cannot secrete insulin as needed. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function and is a lifelong condition. Currently, medical technology cannot cure diabetes; it can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar levels.

[0003] Diabetic patients need to have their blood glucose levels checked before injecting insulin. Currently, most methods can continuously monitor blood glucose and send the data in real time to a remote device for user viewing; this method is called Continuous Glucose Monitoring (CGM). This method requires a detection device to be attached to the skin surface, with its sensor probe inserted into the subcutaneous tissue fluid to complete the measurement.

[0004] Existing body fluid analysis devices cannot achieve good waterproof performance. When users engage in underwater activities such as showering, rinsing, or swimming, water droplets can enter the device. If these droplets come into contact with the electrical connection area, they can cause short circuits or current disturbances, affecting the accuracy and reliability of the detection. Therefore, users often need to remove the device from their body before engaging in underwater activities, causing great inconvenience.

[0005] Therefore, there is an urgent need for a body fluid analysis device with good waterproof performance in the current technology. Summary of the Invention

[0006] This invention discloses a bodily fluid analyzer detection device. A waterproof structure is provided in the electrical connection area within the device. The waterproof structure includes a groove and a sealing ring on the bottom shell. One end of the sealing ring is placed in the groove, and the other end contacts the transmitter housing, preventing water droplets from entering the electrical connection area and avoiding short circuits and current intensity disturbances. Users do not need to remove the detector from their body when performing underwater activities such as showering, rinsing, or swimming, enhancing the user experience and improving the reliability of the detection data.

[0007] This invention discloses a bodily fluid analyte detection device, comprising: a transmitter for transmitting detection data indication signals to a user; a base shell for attaching to the surface of a human body; a sensor mounted on the base shell, including a probe and a conductive adhesive strip, the probe for detecting bodily fluid analyte parameter information and electrically connected to the sensor via the conductive adhesive strip to transmit detection data indication signals to the transmitter; a battery electrically connected to the transmitter for providing power to the transmitter; and a waterproof structure, the waterproof structure including a groove and a sealing ring disposed on the base shell, the lower end face of the sealing ring being placed in the groove and the upper end face contacting the housing of the transmitter, for providing waterproof protection for the electrical connection area of ​​the bodily fluid analyte detection device.

[0008] According to one aspect of the invention, the battery is sealed inside the transmitter, and a waterproof structure is located in the electrical connection area between the sensor and the transmitter.

[0009] According to one aspect of the invention, the battery is sealed within a bottom casing to form a battery sealed chamber, and at least two electrodes are led out from the battery sealed chamber, the electrodes including at least one positive electrode and one negative electrode.

[0010] According to one aspect of the invention, the transmitter is electrically connected to the positive and negative terminals respectively to obtain electrical energy from the battery.

[0011] According to one aspect of the invention, the waterproof structure is located in the electrical connection area between the transmitter and the positive and negative electrodes.

[0012] According to one aspect of the invention, the electrode is an elastic conductive material.

[0013] According to one aspect of the invention, the sealing ring is an insulating rubber ring.

[0014] According to one aspect of the invention, the diameter of the sealing ring is larger than the inner diameter of the groove.

[0015] According to one aspect of the invention, the upper end face of the sealing ring is higher than the upper end face of the groove.

[0016] According to one aspect of the invention, there are two sealing rings, located on the upper and lower sides of the probe, respectively.

[0017] The present invention also discloses a continuous glucose monitoring device, including the body fluid analyte detection device as described above, and a receiver for receiving parameter signals transmitted by the transmitter.

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0019] The body fluid analyzer detection device disclosed in this invention has a waterproof structure in each electrical connection area to prevent water droplets from entering the electrical connection area and avoid short circuits and current intensity disturbances. On the one hand, users do not need to remove the detector from their body when performing underwater activities such as showering, rinsing, and swimming, which enhances the user experience. On the other hand, it reduces the interference of detection data fluctuations caused by current intensity disturbances and improves the reliability of detection data.

[0020] Furthermore, the battery can be directly sealed inside the transmitter to provide power to the transmitter. This achieves waterproofing between the battery and the transmitter without the need for additional waterproofing structures, preventing short circuits that could damage the transmitter and improving the reliability of the body fluid analyzer detection device.

[0021] Furthermore, the battery can be sealed inside the bottom casing and discarded along with it. Each time the user replaces the bottom casing, the battery is replaced at the same time, ensuring the battery always maintains high-performance operation. A waterproof structure is incorporated at the electrical connection area between the transmitter and battery leads to prevent water droplets from entering the connection area, thus avoiding short circuits and current disturbances.

[0022] Furthermore, the electrodes are made of conductive elastic material. When the transmitter comes into contact with the electrodes, it squeezes the electrodes, keeping them in a state of continuous compression, retracting into the grooves and maintaining elasticity. On the one hand, the electrodes and transmitter maintain close contact to ensure the stability of power transmission. On the other hand, it facilitates close contact between the transmitter housing and the sealing ring, improving waterproof performance, preventing water droplets from entering the electrical connection area, and avoiding short circuits and current intensity disturbances.

[0023] Furthermore, the sealing ring is made of insulating rubber. Since rubber is a flexible material and has a certain compressive elasticity, when the transmitter is installed on the base, it exerts a certain squeezing force on the sealing ring, which can better maintain the tight contact between the sealing ring and the transmitter housing, prevent water droplets from entering the electrical connection area, and avoid causing short circuits and current intensity disturbances.

[0024] Furthermore, the diameter of the sealing ring is larger than the inner diameter of the groove, allowing the sealing ring to be more tightly fixed within the groove, thus increasing the reliability of the waterproof structure.

[0025] Furthermore, the upper surface of the sealing ring is higher than the upper surface of the groove, allowing the transmitter housing and the sealing ring to make closer contact, thus increasing the reliability of the waterproof structure.

[0026] Furthermore, there are two sealing rings, located on the upper and lower sides of the probe, respectively. Attached Figure Description

[0038] As mentioned earlier, existing detection devices cannot achieve good waterproof performance. When users engage in underwater activities such as showering, rinsing, or swimming, water droplets can enter the detection device. If these droplets come into contact with the electrical connection area, they can cause short circuits or current disturbances, affecting the accuracy and reliability of the detection. Therefore, users often need to remove the detection device from their bodies before engaging in underwater activities, causing great inconvenience.

[0039] To address this issue, the present invention provides a bodily fluid analysis device with a waterproof structure in each electrical connection area to prevent water droplets from entering the electrical connection area, thus avoiding short circuits and current intensity disturbances. Users do not need to remove the detector from their body when performing underwater activities such as showering, rinsing, or swimming, enhancing the user experience and improving the reliability of the detection data.

[0044] First Embodiment

[0045] Figure 1a This is a three-dimensional structural schematic diagram of the body fluid analysis device according to an embodiment of the present invention.

[0046] The detection device includes a base shell 10, a sensor 11, and a transmitter 12.

[0047] The bottom shell 10 is used to assemble the transmitter 12 and the sensor 11, and to attach the detection device to the skin surface using adhesive tape (not shown in the figure). The bottom shell 10 includes a fixing part and a force-applying part. At least one second engaging part 101 is provided on the bottom shell 10. The second engaging part 101 is used to engage the transmitter 12. Specifically, in this embodiment of the invention, there are two second engaging parts 101. The two second engaging parts 101 are correspondingly disposed on the side wall of the bottom shell 10.

[0048] Here, the fixing part and the force-applying part are relative concepts. Depending on the structural design of the base shell 10 and the transmitter 12, the positions of the fixing part and the force-applying part can be selected in different ways, which will be described in detail below.

[0049] The transmitter 12 is provided with at least one first engaging portion 121. The first engaging portion 121 corresponds to the second engaging portion 101. The transmitter 12 is assembled onto the base shell 10 by the mutual engagement of the second engaging portion 101 and the first engaging portion 121. Obviously, in this embodiment of the invention, the transmitter 12 is provided with two first engaging portions 121, that is, two pairs of mutually engaging first engaging portions 121 and second engaging portions 101.

[0050] Here, the correspondence between the first locking part 121 and the second locking part 101 means that they are equal in number and correspond in position.

[0051] When separating the base shell 10 from the transmitter 12, the fixing part is secured by a finger or other device. By applying force to the force-applying part in one direction using another finger or other auxiliary device, the base shell 10 will disengage, and the second engaging part 101 and the first engaging part 121 will separate from each other, thereby separating the transmitter 12 from the base shell 10. In other words, when separating the base shell 10 from the transmitter 12, the user can separate the two using only one finger applying force to the force-applying part in one direction, making it convenient for the user. After separation, the transmitter can be reused, reducing user costs.

[0052] It should be noted here that failure is a conventional concept in the field of engineering materials. After failure, the material loses its original function, and the failed part cannot be restored. Since the second engaging part 101 is part of the bottom shell 10, the failure of the bottom shell 10 includes the failure of the bottom plate, side wall, or second engaging part 101. Therefore, the failure modes of the bottom shell 10 include one or more of the following: fracture of the bottom plate or side wall, breakage of the bottom shell 10, fracture of the second engaging part 101, and plastic deformation of the bottom shell 10. Obviously, after the bottom shell 10 fails, the bottom shell 10 loses its function and role in engaging the transmitter 12.

[0053] The methods for fixing the fixing part include clamping, supporting, etc. There are no specific restrictions here, as long as the conditions for fixing the fixing part can be met.

[0054] Combination Figure 2 The schematic diagram of the sensor's three-dimensional structure is shown. The sensor 11 is mounted on the bottom shell 10 and includes at least a probe 113 and a conductive strip 114. The probe 113 is used to penetrate human skin to detect the parameters of the body fluid analyte and convert them into electrical signals. The electrical signals are transmitted to the conductive electrodes 122 of the transmitter 12 through the conductive strip 114. The transmitter 12 then transmits the body fluid analyte parameters to the user.

[0055] In this embodiment of the invention, the battery is located inside the transmitter 12 housing, forming a good waterproof seal. The conductive electrode 122 is electrically connected to the conductive adhesive strip 114. A groove 131 is provided on the sensor bottom shell 111 around the conductive adhesive strip 114 for placing a sealing ring 130. The contour of the sealing ring is consistent with the contour of the groove.

[0056] In other embodiments of the present invention, the contour of the sealing ring and the contour of the groove may not be the same. For example, the groove may be square, circular, arc-shaped or a combination thereof, and the corresponding sealing ring may be circular, arc-shaped, square or a combination thereof.

[0057] To better understand the waterproofing principle of the waterproof structure composed of groove 131 and sealing ring 130, refer to... Figure 3a , Figure 3b , Figure 3c .

[0058] Figure 3a Before installing the sealing ring 130, Figure 2 The sensor 11 is shown in a C-C' cross-sectional view. The groove 131 is provided on the sensor bottom shell 111 and surrounds the probe 113 and the conductive silicone 114. The probe 113 is divided into an inner part 113b and an outer part 113a. The outer part 113a is bent or flexed towards the upper end of the bottom shell 111 and laid flat on the bottom shell 111. Figure 3b After installing sealing ring 130, Figure 2 The C-C' cross-sectional view of the sensor 11 shown shows that the contour of the sealing ring 130 is consistent with the contour of the groove 131. The sealing ring 130 is tightly fitted to the groove 131, the probe 13, and the conductive strip 114, and the upper end face of the sealing ring 130 is slightly higher than the upper end face of the conductive strip 114. Here, "slightly higher" means that the upper end face of the sealing ring 130 is 0-5 mm higher than the upper end face of the conductive strip 114, preferably 1 mm. Figure 3c After installing the sealing ring 130 and the transmitter 12, Figure 2 The C-C' cross-sectional view of sensor 11 shows that conductive electrode 122 is in contact with conductive adhesive strip 114, and transmitter housing is in contact with the upper surface of sealing ring 130. It is foreseeable that transmitter housing 12, sealing ring 130, and groove 131 can form a sealed chamber 132, within which the probe body portion 113a, conductive adhesive strip 114, and conductive electrode 122 are located. When the body fluid analyzer is submerged underwater, water droplets are blocked by transmitter housing 12, sealing ring 130, and groove 131, preventing them from entering chamber 132. This provides waterproof protection for the electrical connection area between conductive electrode 122 and conductive adhesive strip 114.

[0059] In other embodiments of the present invention, the sealing ring is slightly larger than the groove, which allows the sealing ring 130 to be installed more tightly in the groove 131, making it less likely to fall off, and the edge of the sealing ring 130 can form a tighter contact with the groove 131, achieving more ideal waterproof protection.

[0060] In other embodiments of the present invention, a sealing ring (not shown in the figure) may be added below the probe body portion 113a and above the bottom shell 111. Together with the sealing ring and groove above the probe body portion 113a, it forms a waterproof structure, which can better prevent water droplets from entering the electrical connection area and achieve a better waterproof effect.

[0061] In other embodiments of the present invention, the sealing ring material is preferably insulating rubber. Since rubber is a flexible material and has a certain compressive elasticity, when the transmitter 12 is installed on the base shell 10, it exerts a certain compressive force on the sealing ring 130, which can better maintain the tight contact between the sealing ring 130 and the housing of the transmitter 10, prevent water droplets from entering the electrical connection area, and avoid causing short circuits and current intensity disturbances.

[0062] Second Embodiment

[0063] Figure 1b This is a schematic diagram of the structure of a body fluid analyzer detection device according to another embodiment of the invention.

[0064] The detection device includes a base shell 20, a sensor 11, and a transmitter 22.

[0065] In this embodiment of the invention, the fixing part and the force-applying part are relative concepts. Depending on the structural design of the base shell 20 and the transmitter 22, the positions of the fixing part and the force-applying part can be chosen in different ways.

[0066] In other embodiments of the present invention, the line l1 connecting the two second engaging portions 202 divides the bottom shell 20 into side A and side B. Side A is provided with a force-applying portion, and side B is provided with a fixing portion.

[0067] Therefore, in this embodiment of the invention, the process of separating the bottom shell 20 and the transmitter 22 is as follows: use one finger to fix the fixing part on side B, and use another finger to apply a force F to the force application part in one direction, so that the second engaging part 202 fails, thereby separating the second engaging part 202 from the first engaging part 221, and separating the transmitter 22 from the bottom shell 20.

[0068] It should be noted that the embodiments of the present invention do not limit the position of the second engaging part 202. For example, two second engaging parts 202 can be disposed on the bottom plate of the bottom shell 20, and no specific limitation is made here.

[0069] The embodiments of the present invention do not impose specific limitations on the shape of the top view of the detection device; its shape can also be a rounded rectangle, a rectangle, a circle, an ellipse, or other shapes.

[0070] The detection device in this embodiment of the invention also includes a battery 208. The battery 208 is used to power the transmitter and is disposed within the bottom housing 20. The location of the battery 208 in the bottom housing 20 is the battery sealing chamber 203. This allows the battery 208 to be replaced simultaneously each time the bottom housing 20 is replaced. Since the transmitter 22 no longer requires a battery, it can be reused continuously, reducing the cost of replacing the transmitter 22 for the user. Simultaneously, the bottom housing 20 continuously uses a high-performance new battery, ensuring the transmitter 22 maintains a continuous high-performance operating state.

[0071] Preferably, in this embodiment of the invention, the top of the battery sealing chamber 203 is flush with the top of the transmitter 22, which reduces the thickness of the detection device.

[0072] The battery sealing chamber 203 can be directly used as a force application point; therefore, the battery is located on side A of l1. Because the battery sealing chamber 203 is relatively thick and has a relatively large area, it is easier for the user to apply force to the battery sealing chamber 203, thus optimizing the user's operating procedures.

[0073] Figure 4 This is a top view of the bottom shell 20.

[0074] Since the battery 208 needs to supply power to the transmitter 22, in this embodiment of the invention, the bottom shell 20 is also provided with at least two electrodes 204. The electrical contacts 223 of the transmitter 22 are electrically connected to the positive and negative terminals of the battery through the electrodes 204, forming an electrical connection area. The battery 208 supplies power to the transmitter through the electrodes 204 and the electrical contacts 223. If water droplets enter the electrical connection area, causing a short circuit, the power supply to the battery 208 will be unstable, and the current intensity received by the transmitter 22 will fluctuate. This may cause fluctuations in the body fluid analyte parameter information received by the transmitter 22 from the probe 113 and the emission parameter information, affecting the reliability of the analyte detection device. Therefore, the electrical connection area needs to be waterproofed. The waterproof structure of the electrical connection area includes a groove 207 and a sealing ring 205.

[0075] To better understand the waterproofing principle of the waterproof structure composed of groove 207 and sealing ring 205, refer to... Figure 5a , Figure 5b , Figure 5c .

[0076] Figure 5a Before installing sealing ring 205, Figure 4The bottom shell 20 is shown in the D-D' cross-sectional view. The battery 208 is placed in the battery sealed chamber 203. The battery sealed chamber 203 is composed of the positive and negative conductive strips 209 of the battery 208 and the shell of the bottom shell 20, forming a completely sealed space. Water droplets cannot enter the battery sealed chamber. The positive and negative conductive strips 209 extend outward from the battery sealed chamber 203 to the groove 207 and cover the bottom end surface of the groove 207. The electrode 204 is located in the middle of the groove 207, with one end fixed to the positive and negative conductive strips 209. Figure 5b After installing sealing ring 205, Figure 4 The bottom shell 20 shown in the D-D' cross-sectional view shows that the sealing ring 205 is located on the upper end face of the groove 207, and its outline is consistent with the groove outline. It can enclose the electrode 204. The upper end face of the sealing ring 205 is slightly higher than the upper end face of the groove 207. Here, "slightly higher" means that the upper end face of the sealing ring 205 is 0-5mm higher than the upper end face of the groove 207, preferably 1mm. Figure 5c After installing the sealing ring 205 and the transmitter 22, Figure 4 The D-D' cross-sectional view of the bottom shell 20 shows that the transmitter power electrode 223 is in contact with the electrode 204 to obtain power from the battery 208. The housing of the transmitter 22 is in contact with the upper surface of the sealing ring 205. It is foreseeable that the housing of the transmitter 22, the sealing ring 205, the groove 207, and the positive and negative conductive strips 209 form a sealed chamber 210, within which the transmitter power electrode 223 and the electrode 204 are located. When the body fluid analyzer detection device is submerged underwater, water droplets are blocked by the housing of the transmitter 22, the sealing ring 205, and the groove 207, preventing them from entering the chamber 210. This provides waterproof protection for the electrical connection areas of the transmitter power electrode 223, the electrode 204, and the positive and negative conductive strips 209.

[0077] In other embodiments of the present invention, the sealing ring is slightly larger than the groove, which allows the sealing ring 205 to be installed more tightly in the groove 207, making it less likely to fall off, and the edge of the sealing ring 205 can form a tighter contact with the groove 207, achieving more ideal waterproof protection.

[0078] In other embodiments of the present invention, electrode 204 is an elastic conductive material that can be electrically connected to transmitter power electrode 223, such as a conductive spring or a conductive sheet. When transmitter 22 is mounted on bottom shell 20, transmitter power electrode 223 squeezes electrode 204, so that electrode 204 is continuously compressed and maintains elasticity. In this way, electrode 204 can maintain continuous close contact with transmitter power electrode 223, ensuring that battery 208 delivers stable power to transmitter 22.

[0079] In other embodiments of the present invention, the sealing ring material is preferably insulating rubber. Since rubber is a flexible material and has a certain compressive elasticity, when the transmitter 22 is installed on the base shell 20, it exerts a certain compressive force on the sealing ring 205, which can better maintain the tight contact between the sealing ring 205 and the housing of the transmitter 20, prevent water droplets from entering the electrical connection area, and avoid causing short circuits and current intensity disturbances.

[0080] In this embodiment of the invention, the waterproof structure of the conductive electrodes 222 of the sensor 11 and the transmitter 22 is the same as that of the first embodiment, and will not be described again here.

[0081] In this embodiment of the invention, the compressed sealing ring 105 applies a certain elastic force to the transmitter 22. When a force F is applied to the force-applying part, the sealing ring 105 provides an elastic force that promotes the separation of the transmitter 22 from the bottom shell 20.

[0082] In summary, this invention discloses a bodily fluid analysis device. A waterproof structure is provided in the electrical connection area of ​​the device to prevent water droplets from entering the electrical connection area, thus avoiding short circuits and current intensity disturbances. Users do not need to remove the detector from their body when performing underwater activities such as showering, rinsing, or swimming, which enhances the user experience and improves the reliability of the detection data.

[0083] This invention also discloses a continuous glucose monitoring device, such as... Figure 6 As shown, after the sensor 11 is installed on the housing 10 (20) and the transmitter 12 (22) is installed on the housing 20, the transmitter 12 (22) can obtain the detection data indication signal of the sensor 11. The transmitter 12 (22) then wirelessly connects with the receiver 30 to transmit the detection data indication signal to the receiver 30 so that the user can know the detection data.

[0084] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
