Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to an implantable analyte monitoring device and a monitoring system. Background Art

[0002] Implantable analyte monitoring devices are used to obtain target analyte data in the human body by implanting them on the surface of the skin. The dynamic blood glucose monitor is a new type of implantable analyte monitoring device that uses sensors implanted in the subcutaneous tissue to record the electrical signals generated by the glucose reaction in the interstitial fluid, and indirectly reflects the measurement of blood glucose. It can continuously monitor the changes in blood glucose in the human body. One end of the sensor of the dynamic blood glucose monitor is implanted in the subcutaneous tissue of the human body to react with glucose and collect electrical signals, and the other end is connected to the transmitter to transmit the electrical signals to the signal processing module. The connection between the sensor and the transmitter needs to be installed and fixed, and the electrical signal is connected at the same time.

[0003] The dynamic blood glucose monitor can be worn on the human body for 7-14 consecutive days and continuously monitor the changes in blood sugar in the human body. In order to ensure that the user does not affect work, life and exercise during wearing, the sensor needs to be effectively fixed to ensure that the sensor can stably collect biological signals and transmit them to the transmitter.

[0004] The prior art uses a clamping spring to fix the sensor and connect the electrical signal. However, this fixing and connection method will cause fatigue of the clamping spring after long-term use. Relying solely on the elasticity of the clamping spring to clamp the sensor and maintain signal connection with the sensor lacks stability, especially after exercise or long-term use, it is easy to have poor contact problems, which will cause the transmitter to be unable to stably receive and process electrical signals, affecting the service life of the dynamic blood glucose monitor.

[0005] At the same time, during the production process of the dynamic blood glucose monitor, the implantation needle and the implantation part of the sensor that will enter the human subcutaneous tissue need to be sealed by the sterilization component, so that the sensor implantation part and the implantation needle can be sterilized and ensured to be sterile before use to prevent bacterial infection during use. However, how to quickly and effectively remove the needle cap used during sterilization during use is a problem that needs to be solved.

[0063] Embodiment 1

[0064] like Figure 1 As shown, this embodiment provides an implantable analyte monitoring device 1111, which is mainly used for monitoring the dynamic changes of blood sugar. However, it is not limited to this, and the implantable analyte monitoring device 1111 can also be used for monitoring other related targets such as lactate, acetylcholine, amylase, bilirubin, cholesterol, and chorionic gonadotropin.

[0065] Specifically, Figure 1 As shown, the implantable analyte monitoring device 1111 is provided with an upper cover 111 and a lower shell 112, and the upper cover 111 and the lower shell 112 are engaged with each other to form a shell.

[0066] like Figure 2 and Figure 3 As shown, the sensor 113 includes an implantation end 1131 and a signal connection end 1132, a connecting portion 1135 is provided between the implantation end 1131 and the signal connection end 1132, the implantation end 1131 is located outside the shell, during use, the implantation end 1131 enters into the subcutaneous tissue of the human body together with the implantation needle, and then the implantation needle quickly rebounds and exits the subcutaneous tissue of the human body, while the implantation end 1131 of the sensor 113 will remain under the subcutaneous tissue of the human body for detecting the interstitial fluid glucose value, the bioelectrode on the implantation end 1131 converts the biosignal of the interstitial fluid glucose value into an electrical signal, and transmits the electrical signal to the signal connection end 1132 through the connecting portion 1135, and the signal connection end 1132 transmits the electrical signal to the circuit board 114, and a signal processing module and a signal transmission module are provided on the circuit board 114, the processing module processes the collected signal, and sends it to a user terminal such as a mobile phone and a computer through the signal transmission module, and the user can realize real-time query of the monitoring data through the terminal.

[0067] In this embodiment, the signal connection end 1132 is in a strip-shaped structure, and the signal connection end 1132 is vertically arranged with the lower shell 112, and a contact 1133 electrically connected to the implant end 1131 can be arranged on one side or both sides of the signal connection end 1132. The number of contacts 1133 is generally 2, and can also be set to 3 or other numbers, and the specific number is determined according to the number of electrodes on the implant end 1131 and the function to be achieved.

[0068] like Figure 2 As shown, the socket 115 is installed on the circuit board 114 , and the function of the socket 115 is to realize the signal connection between the circuit board 114 and the sensor 113 , and to further fix the sensor 113 .

[0069] In order to be suitable for the scenario where the implantable analyte monitoring device 1111 can continuously monitor human analyte data for multiple days, especially to ensure that the user's daily activities such as work, life, and exercise are not affected during the use of the implantable analyte monitoring device 1111, higher requirements are placed on the installation and fixation of the sensor 113 and the stability of the signal.

[0070] To solve the sensor 113 installation problem, refer to Figure 4The fixing assembly includes a slot 1121, a strip-shaped fixing rib is convexly provided along the upper end surface of the lower shell 112, and a slot 1121 matching the specification of the signal connection terminal 1132 is concavely provided along the extending direction of the fixing rib, and the bottom of the signal connection terminal 1132 is fixed by engaging the signal connection terminal 1132 with the slot 1121. Of course, the slot 1121 can also be directly provided on the lower shell 112 to engage and fix the bottom of the signal connection terminal 1132.

[0071] Continue to refer Figure 4 The fixing assembly also includes several groups of clamping members 1122. One group of clamping members 1122 consists of two clamping members 1122 respectively arranged along the two sides of the card slot 1121. The two clamping members 1122 in the same group are clamped and fixed to achieve vertical fixation of the middle and top of the signal connection terminal 1132.

[0072] Continue to refer Figure 4 A through hole is provided at the center of the lower shell 112 for passing the implant needle and the sensor 113. A mounting seat 1125 is provided on the upper end surface of the lower shell 112 at the outer edge of the through hole. A slot hole opposite to the position of the through hole is provided on the mounting seat 1125. The slot hole is also used to pass the sensor 113 and the implant needle. A sealing groove 1126 is recessed on the upper end surface of the mounting seat 1125. The connecting portion 1135 of the sensor 113 passes through the sealing groove 1126 and extends into the slot hole and is connected to the implant end 1131. During the sterilization process, in order to ensure the sealing effect of the implant end 1131, glue will be poured into the sealing groove 1126 to achieve isolation between the implant end 1131 of the sensor 113 and the signal connection end 1132. In order to solve the problem of stable signal connection of the sensor 113, refer to Figure 5 The signal connection between the sensor 113 and the circuit board 114 is achieved through the socket 115.

[0073] Specifically, Figure 6 As shown, the socket 115 includes a base 1151 and a terminal 1152. The base 1151 is made of insulating material. A slot 1153 is set at the middle position of the bottom of the socket 115 along the length direction of the socket 115. A plurality of limit grooves 1154 corresponding to the position and matching the specifications of the clamping member 1122 are set on both sides of the slot 1153. When the socket 115 is plugged into the signal connection terminal 1132 of the sensor 113, the signal connection terminal 1132 is inserted and engaged in the slot 1153, and the clamping member 1122 is fixed in the limit groove 1154.

[0074] like Figure 6 As shown, a groove 1155 is provided on the side wall of the base 1151 near the implant end 1131, corresponding to Figure 2As shown, a groove 1134 is provided between the connecting portion 1135 and the signal connection end 1132, and the width of the groove 1134 is the same as the width of the side wall of the base 1151, so that when the base 1151 is engaged with the sensor 113, the groove 1155 and the groove 1134 are engaged with each other. Of course, the groove 1155 may not be provided on the base 1151, and in this case, it is only necessary to increase the depth of the groove 1134 so that the groove 1134 can give way to the side wall of the base 1151.

[0075] like Figure 7 As shown, the terminal 1152 can be made of copper, silver or other conductive metal materials by integral bending and forming, and the terminal 1152 includes a crimping portion 11521 connected to the contact 1133, a connecting portion 11523 connected to the circuit board 114, and a conducting portion 11522 disposed between the crimping portion 11521 and the connecting portion 11523. One end of the conducting portion 11522 is connected to the crimping portion 11521 and the other end is connected to the connecting portion 11523. The conducting portion 11522 conducts the electrical signal on the crimping portion 11521 to the connecting portion 11523. The connecting portion 11523 is connected to the signal input terminal on the circuit board 114, and transmits the electrical signal to the circuit board 114 for signal processing.

[0076] like Figure 7 As shown, the crimping portion 11521 is configured as a hook-shaped structure, and the hook tip of the crimping portion 11521 extends toward the conductive portion 11522. During the crimping process between the crimping portion 11521 and the contact 1133, the outermost position of the crimping portion 11521 relative to the conductive portion 11522 contacts the contact 1133, and at the same time, the contact 1133 squeezes the outermost position of the crimping portion 11521, so that the crimping portion 11521 is elastically deformed to move closer to the conductive portion 11522. Under the action of the elastic force, the crimping portion 11521 can maintain long-term stable contact with the contact 1133, thereby improving the stability of the signal.

[0077] like Figure 6 and Figure 7As shown, a second mounting groove 1157 is vertically opened on the base 1151, and the conducting portion 11522 of the terminal 1152 is fixed in the second mounting groove 1157. A third mounting groove 1158 connected to the second mounting groove 1157 is opened on the top of the base 1151. The connecting portion 11523 of the terminal 1152 passes through the third mounting groove 1158 and is welded to the circuit board 114. During welding, the connecting portion is ensured to be connected to the signal input port of the circuit board 114, which not only can connect and fix the entire socket 115 to the circuit board 114, but also can realize the conduction of signals between the socket 115 and the circuit board 114. A first mounting groove 1156 is opened between the second mounting groove 1157 and the slot 1153. The first mounting groove 1156 is to ensure that the outermost position of the crimping portion 11521 can extend into the slot 1153 and abut against the contact 1133 on the signal connection end 1132.

[0078] When irradiation sterilization is used for sterilization, the circuit board is not assembled in the shell during irradiation sterilization because the electron beam will cause charge accumulation when irradiating the electronic components, thereby damaging the electronic components. Therefore, the circuit board is assembled after the irradiation sterilization is completed.

[0079] In order to realize the installation and fixation of the upper cover 111 and the lower shell 112, refer to Figure 4 A plurality of first buckles 1123 are arranged along the edge of the upper end surface of the lower shell 112, and a plurality of slots corresponding to the positions of the first buckles 1123 are arranged on the side wall of the upper cover 111. The lower shell 112 and the upper cover 111 are snap-connected by engaging the first buckles 1123 with the slots on the upper cover 111.

[0080] In order to realize the installation and fixation of the circuit board 114, continue to refer to Figure 4 A plurality of second buckles 1124 are arranged along the edge of the upper end surface of the lower shell 112. The height difference between the second buckles 1124 and the first buckles 1123 is equal to or slightly less than the thickness of the circuit board 114. The lower end surface of the circuit board 114 is supported by the first buckles 1123 and the upper end surface is limited by the second buckles 1124, so as to realize the installation and fixation of the circuit board 114.

[0081] like Figure 2 As shown, the battery 1141 is located on the lower end surface of the circuit board 114. The purpose is to ensure that the battery 1141 and the socket 115 are located in the same direction, which can effectively save the space occupied by the battery 1141, ensure that the internal layout of the entire monitoring device 11 is more reasonable, and reduce the volume of the monitoring device 11.

[0082] Embodiment 2

[0083] like Figure 8As shown, this embodiment provides an implantable analyte monitoring system 1, which is mainly used for monitoring the dynamic changes of blood sugar. However, it is not limited to this, and the implantable analyte monitoring device 1111 can also be used for monitoring other related targets such as lactate, acetylcholine, amylase, bilirubin, cholesterol, and chorionic gonadotropin.

[0084] like Figure 8 As shown, the monitoring system includes a shell and a protective cover 122 detachably connected to the shell. A needle assisting assembly 16 for implementing needle assisting and needle withdrawing actions is arranged inside the shell. An implantable analyte monitoring device 1111 is arranged at the bottom of the needle assisting assembly 16.

[0085] like Figure 8 As shown, the needle-assisting assembly 16 includes a needle-assisting unit and a needle-retracting unit. The needle-assisting unit is configured to puncture the implantation needle and the implantation end 1131 into the subcutaneous tissue of the patient after pressing the activation button 124 on the top cover 123. The needle-retracting assembly retracts the implantation needle, while the implantation end 1131 remains in the subcutaneous tissue of the patient. It is worth noting that the implanter is a conventional medical component in the medical field and is not the focus of protection of the present utility model.

[0086] When manufacturing the monitoring device, it is necessary to sterilize the implant end 1131 of the sensor 113 and the implant needle that will enter the human body to prevent bacteria and viruses on the implant end 1131 and the implant needle from entering the human body and causing infection.

[0087] In order to achieve sterilization operation, Figure 8 As shown, a needle cap 14 is provided on the monitoring system, and the needle cap 14 is detachably connected to the needle seat. The implant end 1131 and the implant needle that need to be sterilized are inserted into the needle cap 14, and the needle seat, the mounting seat 1125, the sealant filled in the sealing groove 1126, the lower shell 112 and the sealing ring seal the open end of the needle cap 14 together to form a sterilization cavity, and the sterilization operation of the implant end and the implant needle is completed in the sterilization cavity. After the irradiation sterilization is completed, the bacteria and viruses on the implant end 1131 and the implant needle are effectively killed and meet the standard of being able to enter the human body. At the same time, because the implant needle and the implant end 1131 are sealed in the needle cap 14, the implant end 1131 and the implant needle can be stored under sterile conditions.

[0088] When in use, the needle cap 14 needs to be removed before the needle is inserted, so that the implantation needle and the implantation end 1131 can be exposed to the air, which facilitates the implantation needle and the implantation end 1131 to enter the subcutaneous tissue of the human body. If the needle cap 14 is removed by manual operation, since the implantation needle will be exposed to the air, improper operation may cause the implantation needle to pierce the skin of the operator, posing a safety hazard, and may also cause contamination of the implantation needle. Improper operation may also cause the needle cap 14 to contact and collide with the implantation needle. In severe cases, the implantation needle may be deformed or bent, which poses a great risk to the implantation needle entering the subcutaneous tissue of the human body. Therefore, how to quickly and effectively remove the needle cap 14 is also a problem that the monitoring system needs to solve.

[0089] In order to solve the problem of disassembling the needle cap 14, Fig. 9 As shown, in this embodiment, the needle cap 14 and the protective cover 122 are fixed by a connector 15, the protective cover 122 is connected to the bottom of the upper shell 121 by a threaded manner, and the protective cover 122 is also connected to the upper shell 121 by a buckle or other means. When the protective cover 122 is removed from the upper shell 121, the protective cover 122 drives the needle cap 14 to separate from the monitoring device through the connector 15, so that the needle cap 14 can be quickly and effectively removed.

[0090] Specifically, Fig.10 As shown, the connecting member 15 includes a base 151, a first fastener 152 and a second fastener 153. A fixing hole is formed through the protective cover 122. In this embodiment, the specification of the base 151 is larger than the specification of the fixing hole, thereby ensuring that the base 151 is always located on the outside of the protective cover 122 and does not enter the inside of the protective cover 122 through the fixing hole.
