Description

Technical Field

[0001] This utility model relates to the field of transmitter technology, and in particular to a sealing structure for a transmitter. Background Technology

[0002] Dynamic monitoring, with its advantages of continuity, accuracy, and minimal invasiveness, has become a current research hotspot. Continuous dynamic monitoring of analytes employs a minimally invasive implantation method, combining advanced biochemical sensor (i.e., detection sensor) technology and wireless transmission technology to achieve long-term, stable, and accurate monitoring of analyte concentrations (generally, a needle is launched from an assist device and inserted into the body, carrying the sensor's detection probe to the target location; then the needle is removed, but the detection probe remains in the patient's body for real-time monitoring).

[0003] Portable transmitters (such as continuous glucose monitors and implantable biosensors) need to achieve high-precision sealing to ensure the long-term stability of internal electronic components (such as detection sensors, circuit boards, and power supplies), while also being compatible with the dynamic movement requirements of puncture needles and clinical aseptic operation standards.

[0004] The existing transmitter housing generally integrates the aforementioned electronic components. Currently, the sealing of internal electronic components mainly involves designing individual seals (such as gaskets) for each component. This results in a large number of parts and complex assembly processes, which reduces product reliability to a certain extent and makes the seals prone to failure due to assembly methods.

[0005] Therefore, a sealing structure for the transmitter is urgently needed. Utility Model Content

The probe is at least partially installed within the accommodating cavity, such that the probe portion is coaxially arranged with the perforation, and the probe portion is located inside the puncture needle; the upper cover has an annular protrusion corresponding to the annular groove on its inner side, and a protrusion adapted to the groove; when the upper cover is installed at the opening end of the base, the annular protrusion is embedded in the annular groove and a first gap is formed between the annular protrusion and the annular groove, the protrusion is embedded in the groove and a second gap is formed between the protrusion and the groove, and a portion of the structure of the electronic connection portion forms a third gap with the inner wall of the installation channel, and the third gap communicates with the accommodating cavity; the first gap, the second gap and the third gap are all filled and sealed with adhesive.

[0008] Preferably, the top cover also has a clearance groove extending through the top cover, the clearance groove being located inside the protrusion; when the top cover is installed at the open end of the base, the first protrusion is inserted into the clearance groove, and the puncture needle is at least partially located in the clearance groove.

[0009] Preferably, the transmitter further includes a first sealing component and a second sealing component. When the first sealing component is detachably connected to the second sealing component, the first sealing component abuts against the top of the first protrusion and forms a sealing contact therewith, and the second sealing component abuts against the outside of the base and forms a sealing contact therewith. The puncture needle is fixedly connected to the first sealing component, and the second sealing component at least partially forms a receiving groove. A sterilization chamber for receiving the puncture needle and probe portion is formed between the receiving groove and the base.

[0011] Preferably, the second sealing assembly includes: a lower connector, on which the receiving groove is located; and a second sealing ring, which is fitted into one end of the base; when the first sealing assembly is detachably connected to the second sealing assembly, the second sealing ring is compressed and confined between the lower connector and the base.

[0012] Preferably, the angle between the electronic connector and the probe is approximately 90 degrees, a first positioning protrusion is formed on the electronic connector, and a first positioning groove is provided in the accommodating cavity; the first positioning protrusion is embedded in the first positioning groove to realize the installation of the electronic connector in the accommodating cavity.

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 9As shown, this utility model embodiment provides a sealing structure for a transmitter, which also has at least a detection sensor 1 and a puncture needle 2 (the detection sensor 1 and the puncture needle 2 are prior art). The detection sensor 1 has an electronic connection part 11 and a probe part 12. The puncture needle 2 has a side groove 21 distributed along its length direction. The side groove 21 allows the probe part 12 to be placed inside the puncture needle 2. The sealing structure includes at least a base 3 and a top cover 4.

[0023] The base 3 has an open cavity 31. The open end of the base 3 has an annular groove 32 coaxially arranged with the cavity 31. A first protrusion 33 is formed inside the cavity 31. The top of the first protrusion 33 has a groove 331 that is connected to the end and a through hole 332 that penetrates the base 3 to accommodate the puncture needle 2. One side of the first protrusion 33 also has an installation channel 333. The electronic connection part 11 passes through the installation channel 333 and is at least partially installed in the cavity 31 so that the probe part 12 is coaxially arranged with the through hole 332 and the probe part 12 is located inside the puncture needle 2. The inner side of the upper cover 4 has an annular protrusion 41 corresponding to the annular groove 32 and a protrusion 42 adapted to the groove 331. like Figure 3 As shown, when the upper cover 4 is installed at the open end of the base 3, the annular protrusion 41 is embedded in the annular groove 32 and a first gap 34 is formed between the annular protrusion 41 and the annular groove 32. The protrusion 42 is embedded in the groove 331 and a second gap 35 is formed between the protrusion 42 and the groove 331. A portion of the structure of the electronic connection part 11 forms a third gap 36 with the inner wall of the installation channel 333, and the third gap 36 communicates with the accommodating cavity 31. The first gap 34, the second gap 35 and the third gap 36 are all filled and sealed with adhesive (the adhesive can be a two-component epoxy or UV adhesive).

[0024] In this embodiment, the transmitter sealing structure mainly adopts a glue injection sealing design; the electronic connection part 11 of the detection sensor 1 passes through the mounting channel 333 of the base 3 into the receiving cavity 31, and its probe part 12 is coaxially aligned with the perforation 332 of the base 3 and placed inside the puncture needle 2. When the upper cover 4 is fastened to the base 3, the annular protrusion 41 is embedded in the annular groove 32 to form a first gap 34, the protrusion 42 is embedded in the groove 331 to form a second gap 35, and the electronic connection part 11 and the inner wall of the mounting channel 333 form a third gap 36. After the electronic connection part 11 is installed on the base 3 and the upper cover 4 is not installed, two-component epoxy glue or UV glue (such as...) is filled into the first gap 34, the second gap 35 and the third gap 36. Figure 3The shaded area in the square grid indicates the part where the glue is applied. Then, the top cover 4 is fastened to the base 3, achieving a comprehensive seal between the top cover 4 and base 3, and between the detection sensor 1 and base 3. This triple-seal design effectively prevents the intrusion of external environments (such as moisture and dust), improving the long-term operational stability of the transmitter housing (i.e., the base and top cover together form the housing). Replacing the traditional mechanical seal structure with gap-filling glue reduces the number of parts and assembly steps, contributing to the overall miniaturization of the transmitter design.

[0025] In addition, the mounting channel 333 serves as both a positioning and sealing function for the sensor 1. By injecting adhesive through the gap between the electronic connection part 11 and the inner wall of the channel, the stability of the probe part 12 after precise alignment with the perforation 332 is ensured, while avoiding assembly deviations that may be caused by using traditional sealing parts (such as O-rings, soft rubber seals, etc.).

[0026] In some practical applications, the upper cover 4 also has a clearance groove 43 extending through it (e.g., Figure 5 and Figure 6 The clearance groove 43 is located inside the protrusion 42; when the upper cover 4 is installed at the open end of the base 3, the first protrusion 33 is inserted into the clearance groove 43, and the puncture needle 2 is at least partially located in the clearance groove 43. The puncture needle 2 can move up and down, and the puncture needle 2 is inserted into the patient's body to bring the probe part 12 into the patient's body as well. Then the puncture needle 2 is removed, and the probe part 12 remains in the patient's body for real-time monitoring of the concentration of analytes (such as various parameters detected by the blood-adaptive detection sensor 1).

[0027] After the puncture needle 2 is installed through the perforation 332 of the base 3, it is located within the clearance groove 43 of the upper cover 4 and can move up and down axially. When the transmitter is working, the puncture needle 2 is inserted into the patient's body, bringing the probe part 12 located inside it into the detection position within the patient's body; subsequently, the puncture needle 2 is withdrawn, while the probe part 12 remains in the body to monitor the analyte concentration in real time. The clearance groove 43 provides space for the up and down movement of the puncture needle 2, and at the same time, the first protrusion 33 is used to determine the assembly position of the upper cover 4 through the insertion and engagement with the clearance groove 43.

[0028] In some practical applications, refer to Figures 1 to 2 As shown, the transmitter also includes a first sealing component 5 and a second sealing component 6. When the first sealing component 5 is detachably connected to the second sealing component 6, the first sealing component 5 abuts against the top of the first protrusion 33 and forms a sealing contact therewith. The second sealing component 6 abuts against the outside of the base 3 and forms a sealing contact therewith. The puncture needle 2 is fixedly connected to the first sealing component 5. The second sealing component 6 at least partially forms a receiving groove 611. A sterilization chamber for accommodating the puncture needle 2 and the probe part 12 is formed between the receiving groove 611 and the base 3.

[0029] Specifically, the first sealing assembly 5 includes an upper connector 51 and a first sealing ring 52; the first sealing ring 52 is embedded in one end of the first protrusion 33, and the puncture needle 2 is located inside the first sealing ring 52; when the first sealing assembly 5 is detachably connected to the second sealing assembly 6, the first sealing ring 52 is squeezed and limited between the first protrusion 33 and the upper connector 51.

[0030] The second sealing assembly 6 includes a lower connector 61 and a second sealing ring 62, with the receiving groove 611 located on the lower connector 61; the second sealing ring 62 is embedded in one end of the base 3; when the first sealing assembly 5 is detachably connected to the second sealing assembly 6, the second sealing ring 62 is squeezed and confined between the lower connector 61 and the base 3.

[0031] In this embodiment, the sealing and sterilization process of the transmitter is as follows: The puncture needle 2 is fixed to the upper connector 51 of the first sealing assembly 5 (in actual applications, the upper connector 51 is usually injection molded so that the puncture needle 2 and the upper connector 51 form a whole). The probe part 12 is located on the lower side of the perforation 332 of the base 3 and is coaxially assembled with the puncture needle 2. The lower connector 61 of the second sealing assembly 6 forms a sterilization chamber with the base 3 through the receiving groove 611. The puncture needle 2 and the probe part 12 are located in the sterilization chamber. The sterilization chamber is pre-sealed by the first sealing ring 52 (embedded in the end of the first protrusion 33) and the second sealing ring 62 (embedded in the end of the base 3).

[0032] When the first sealing assembly 5 and the second sealing assembly 6 are detachably connected, the upper connector 51 squeezes the first sealing ring 52 to make it fit tightly against the first protrusion 33 and the upper connector 51, and the lower connector 61 squeezes the second sealing ring 62 to make it fit tightly against the base 3 and the lower connector 61, forming a double elastic seal for the sterilization chamber; at the same time, the puncture needle 2 can move axially inside the sealing ring to ensure that the sealing performance is not affected during the puncture action.

[0033] Before assembly, the lower connector 61 is connected to the upper connector 51 to achieve an internal sterile environment through a sterilization process, and the probe part 12 and the puncture needle 2 are sterilized. Then, the circuit board 7 and the power supply 8 are assembled, and the upper cover 4 is assembled to achieve sterile retention of the probe part 12 and the puncture needle 2. During clinical use, the second sealing component 6 is removed, and the puncture needle 2 can drive the probe part 12 to complete the puncture-retention operation.

[0034] The adhesive sealing (first gap 34, second gap 35, third gap 36) achieves long-term static sealing of the internal components of the transmitter (detection sensor 1, accommodating cavity 31), while the elastic sealing rings (first sealing ring 52, second sealing ring 62) achieve detachable dynamic sealing of the sterilization chamber.

[0035] It should be noted that the detachable connection between the upper connector 51 and the lower connector 61 can be achieved at least in the following manner: the upper connector 51 has two hooks 511, the first protrusion 33 is provided with two limiting holes 334 penetrating the base 3, and the lower connector 61 is provided with two fasteners 612; when the upper connector 51 and the lower connector 61 are connected, the two hooks 511 are slidably inserted into the two limiting holes 334 respectively, and are respectively fastened to the two fasteners 612 below, thereby realizing the connection between the upper connector 51 and the lower connector 61.

[0036] In some practical applications, refer to Figure 3 and Figure 5 As shown, the angle between the electronic connection part 11 and the probe part 12 tends to be ninety degrees. A first positioning protrusion 111 is formed on the electronic connection part 11, and a first positioning groove 311 is provided in the accommodating cavity 31. The first positioning protrusion 111 is embedded in the first positioning groove 311 to realize the installation of the electronic connection part 11 in the accommodating cavity 31. The ninety-degree bending structure makes the layout of the detection sensor 1 more suitable for the space of the accommodating cavity 31.

[0037] In other practical applications, in summary, referring to... Figures 4 to 6 As shown, a circuit board 7 and a power supply 8 for powering the circuit board 7 are also installed in the accommodating cavity 31. The circuit board 7 is electrically connected to the electronic connection part 11. Specifically, a plurality of second positioning grooves 71 are formed on the side edge of the circuit board 7, and a plurality of second positioning protrusions 312 are formed in the accommodating cavity 31. The plurality of second positioning protrusions 312 are respectively inserted and engaged with the plurality of second positioning grooves 71 to realize the positioning of the circuit board 7 relative to the base 3.

[0038] Specifically, the circuit board 7 is also provided with a strip groove 72, and connection endpoints 73 are provided on both sides of the strip groove 72. The electronic connection part 11 is configured as a sheet structure with corresponding conductive contacts on the sheet structure. The electronic connection part 11 is embedded in the strip groove 72 and the conductive contacts are in contact with the connection endpoints 73 to realize the electrical signal connection between the electronic connection part 11 and the circuit board 7.

[0039] In this embodiment, the sheet-like electronic connection part 11 is embedded in the strip groove 72 of the circuit board 7 to achieve mechanical fixation of the detection sensor 1 and the circuit board 7 and direct electrical signal connection. The circuit board 7 is positioned by inserting into the second positioning protrusion 312 of the accommodating cavity 31 through the second positioning groove 71 on the side edge. The power supply 8 supplies power to the circuit board 7. The whole is integrated into the accommodating cavity 31 and sealed by adhesive (adhesive is applied at the first gap 34, the second gap 35 and the third gap 36) to achieve sealing protection.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
