Description

Technical Field

[0001] This utility model relates to the field of implantation technology, and in particular to a sterilization component with a monitoring probe. Background Technology

[0002] Continuous monitoring of human analytes is of significant value in understanding diet, health, medication use, and exercise status. Continuous analyte monitoring utilizes implantable probes to monitor analyte signals, which are then transmitted to a receiving device via a transmitter, enabling uninterrupted, visualized analyte monitoring around the clock. To ensure clinical safety, the contact points between the probe and the puncture needle undergo rigorous sterilization. Furthermore, the structural stability of the assembled probe and puncture needle, as well as their sealing performance in the unopened state, must be guaranteed to prevent the intrusion of external contaminants.

[0003] Many existing in vivo continuous analyte concentration monitors suffer from easily loosened sterilization components, leading to ineffective and improper sealing. This results in the failure of the sterility barrier, causing sterilization failure of the biochemical sensor (i.e., monitoring probe) and the metal needle (i.e., puncture needle). Furthermore, some existing products sterilize the transmitter and biochemical sensor together via radiation, which can damage the enzymes on the biochemical sensor and the circuitry of the transmitter to varying degrees. Other methods sterilize the biochemical sensor and transmitter separately before assembly, increasing material costs, design complexity, and the complexity of patient operation.

[0004] Therefore, there is an urgent need for a sterilization component with a monitoring probe. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] Dynamic monitoring, with its advantages of continuity, accuracy, and minimal invasiveness, has become a current research hotspot. However, implantable biochemical sensors, used to obtain data on target analytes within the human body by being implanted on the skin surface, may cause skin irritation or infection with prolonged use, and the stability and accuracy of the biochemical sensors may also be affected. Therefore, an in vivo continuous analyte concentration monitoring device aims to solve the problems of signal drift, poor biocompatibility, limited battery life, and discontinuous data from in vitro monitoring devices associated with existing implantable biochemical sensors. The key innovation lies in employing a minimally invasive implantation method, combined with advanced biochemical sensor technology and wireless transmission technology, to achieve long-term, stable, and accurate analyte concentration monitoring.

[0022] Reference Figures 1 to 11 As shown, this utility model embodiment provides a sterilization component with a monitoring probe, which belongs to a part of the structure of an in vivo continuous analyte concentration monitoring device; it includes a sensor probe 1 for detection and a puncture needle 2 with a side opening. The probe part 11 of the sensor probe 1 (i.e., the monitoring probe, which is prior art and will not be described in detail here) is at least partially placed inside the puncture needle 2 and moves relative to it; the sterilization component also includes a housing 3, a first sealing component 4 and a second sealing component 5.

[0023] The housing 3 has a through hole 31 penetrating its body and two limiting holes 32 located on both sides of the through hole 31. The sensor probe 1 is mounted on the housing 3. The first sealing assembly 4 has at least two hooks 411 arranged opposite to each other. The puncture needle 2 is mounted on the first sealing assembly 4. The two hooks 411 of the first sealing assembly 4 are slidably inserted into the two limiting holes 32 respectively, and the puncture needle 2 is at least partially inserted into the through hole 31. The second sealing assembly 5 has at least two fasteners 511 arranged opposite to each other, and the second sealing assembly 5 at least partially forms a receiving groove 512. The two fasteners 511 can be fastened to the two hooks 411 respectively, so that the first sealing assembly 4 and the second sealing assembly 5 abut against both sides of the housing 3 and form a sealing contact. A sterilization chamber for accommodating the puncture needle 2 and the probe part 11 is formed between the receiving groove 512 and the housing 3.

[0024] Currently, the housing 3 of in vivo continuous analyte concentration monitoring devices generally has only one hole through which components such as the hook 411, the probe part 11 of the sensor probe 1, and the puncture needle 2 pass. This can lead to poor connection stability and, in the case of unstable connection, may also cause a decrease in sealing performance. The second sealing component 5 of this application fastens the hook 411 of the first sealing component 4 with the fastener 511, so that the two abut against the two sides of the housing 3 to form a seal. The receiving groove 512 forms a sealed sterilization chamber with the housing 3. Therefore, during the sterilization operation, only the sterilization components assembled on the housing 3 are sterilized, achieving targeted sterilization of the end of the puncture needle 2 and the probe part 11 of the sensor probe 1. When in use, the second sealing component 5 is removed to expose the puncture needle 2. The end of the puncture needle 2 and the probe part 11 of the sensor probe 1 are implanted into the skin in a minimally invasive manner. Then, the puncture needle 2 is moved away from the skin, while the probe part 11 remains in the body to monitor the analyte concentration. At the same time, the sensor element and electrical component inside the housing 3 remain safe because they are not in contact with the sterilization process.

[0025] The cooperation of two limiting holes 32 and hooks 411 avoids component wobbling or instability caused by traditional single-hole designs, ensuring the coaxiality of the puncture needle 2 and the probe. The tight contact between the first sealing component 4 and the second sealing component 5 and the housing 3 forms an independent sterilization chamber, reducing the risk of external contaminant intrusion. Simultaneously, the stable cooperation of the two limiting holes 32 and the two hooks 411 prevents wobbling, thus ensuring a certain degree of sealing between the first sealing component 4 and the second sealing component 5 and the housing 3. Furthermore, in the sterilization process of the testing device, only the probe 11 and the sterilization components containing the tip of the puncture needle 2, which come into contact with the human body, need to be sterilized. There is no need to disinfect the entire structure, protecting the internal sensors and electrical components of the housing 3 from damage. The smaller sterilization area significantly reduces costs compared to traditional overall sterilization methods. Moreover, the detachable design between the second sealing component 5 and the first sealing component 4 facilitates rapid exposure of the puncture needle 2 for clinical implantation.

[0026] Specifically, refer to Figure 5 and Figure 7 As shown, the first sealing assembly 4 includes an upper sealing member 41, with two hook members 411 symmetrically arranged at one end of the upper sealing member 41; a first sealing ring 42 is fitted into one end of the upper sealing member 41, and the puncture needle 2 is located inside the first sealing ring 42; when the two fasteners 511 are respectively fastened to the two hook members 411, the first sealing ring 42 is compressed and limited between the housing 3 and the upper sealing member 41. The second sealing assembly 5 includes a lower sealing member 51, with two fasteners 511 symmetrically arranged at one end of the lower sealing member 51; a second sealing ring 52 is fitted into one end of the lower sealing member 51; when the two fasteners 511 are respectively fastened to the two hook members 411, the second sealing ring 52 is compressed and limited between the housing 3 and the lower sealing member 51.

[0027] The two hooks 411 of the upper seal 41 are slidably inserted into the two limiting holes 32 of the housing 3. The puncture needle 2 passes through the first sealing ring 42 at the end of the upper seal 41 and is coaxially aligned with the sensor probe 1. At this time, the first sealing ring 42 is in a pre-compressed state. The two fasteners 511 of the lower seal 51 are engaged with the hooks 411 of the first sealing assembly 4, which drives the second sealing ring 52 at the end of the lower seal 51 to squeeze the other side of the housing 3, forming a double sealing structure on both sides of the housing 3 to ensure the sealing performance of the sterilization chamber.

[0028] In some practical applications, based on any of the above implementation methods: Refer to Figure 2 , Figure 3 , Figures 8 to 11As shown, each of the hooks 411 includes a cantilever 4112 and a first protrusion 4113 located on the inner side of the tail end of the cantilever 4112; when the two fasteners 511 are respectively fastened to the two hooks 411, the cantilever 4112 of each hook 411 is located on the outer side of the corresponding fastener 511 and the first protrusion 4113 abuts against the end of the corresponding fastener 511, so as to realize the limiting of the second sealing assembly 5 relative to the housing 3 in the axial direction of the perforation 31.

[0029] In this embodiment, axial fixation is achieved through the mechanical interlocking of the hook 411 and the fastener 511. The hook 411 of the first sealing assembly 4 includes a cantilever 4112 and a first protrusion 4113 on the inner side of the tail end. When the fastener 511 of the second sealing assembly 5 is fastened, the outer side of the cantilever 4112 fits against the inner wall of the fastener 511, and the first protrusion 4113 abuts against the end of the fastener 511, forming a limit along the axial direction of the through hole 31, preventing the second sealing assembly 5 from moving axially relative to the housing 3, thereby causing the housing 3 to be passively clamped between the first sealing assembly 4 and the second sealing assembly 5.

[0030] Furthermore, during the fastening process, the first sealing ring 42 and the second sealing ring 52 undergo elastic deformation due to axial compression, filling the gap between the housing 3 and the sealing assembly. Combined with the limiting action of the hook 411 and the fastener 511, this ensures that the sterilization chamber remains sealed at all times. The axial limiting action of the first sealing assembly 4 and the second sealing assembly 5, along with the combination of the first sealing ring 42 and the second sealing ring 52, not only prevents leakage due to gap changes at the sealing surface, but also, under the elastic force of the first sealing ring 42 and the second sealing ring 52, makes the compression between the first protrusion 4113 and the end of the fastener 511 more tight, thus ensuring the connection stability of the first sealing assembly 4 and the second sealing assembly 5 to a certain extent.

[0031] Specifically, refer to Figure 8 and Figure 11As shown, a locking block 4114 is provided on the first protrusion 4113, and the end of the fastener 511 has a locking groove 5111 that is adapted to the locking block 4114; when the two fasteners 511 are respectively fastened to the two hooks 411, each locking block 4114 is embedded in the corresponding locking groove 5111 to achieve circumferential positioning of the lower seal 51 relative to the upper seal 41. The cantilever 4112 of the hook component 411 has a certain degree of elasticity and can deform slightly when fastened. When the fastener 511 fastens the hook component 411, the locking block 4114 is embedded in the locking groove 5111 to form a circumferential mechanical interlock, preventing the lower seal 51 from rotating relative to the upper seal 41 around the axis of the perforation 31. Combined with the axial limiting of the original first protrusion 4113 abutting the end of the fastener 511, and the circumferential limiting of the newly added locking block 4114-locking groove 5111, the sealing assembly is completely fixed in the axial (perforation 31 direction) and circumferential (rotation direction) directions, ensuring that the sterilization chamber does not shift or deflect during sterilization, transportation and implantation.

[0032] The locking block 4114 matches the shape of the locking groove 5111 (such as wedge, rectangle, etc.). When the lower seal 51 is assembled and installed in place, the locking block 4114 is embedded in the locking groove 5111, which will generate obvious feedback, making it easy for the operator to sense the installation position of the lower seal 51. When it is necessary to remove the seal 51, it is necessary to flip the lower seal 51 with a little force before it can be removed.

[0033] Based on the above implementation: In some practical applications, the end of the fastener 511 is composed of an inclined surface 5112 and a plane 5113 connecting the inclined surface 5112 (e.g., Figure 11 The locking groove 5111 is located on the plane 5113; the second sealing ring 52 abuts against the end of the housing 3, and during the rotation of the lower sealing member 51, the locking block 4114 first contacts the inclined surface 5112 and moves along the inclined surface 5112 to the plane 5113 to be embedded in the locking groove 5111. The second sealing ring 52 of the second sealing assembly 5 abuts against the end of the housing 3. At this time, the lower sealing member 51 is rotated, and the locking block 4114 contacts the inclined surface 5112 at the end of the fastener 511 to form an initial positioning. As the lower sealing member 51 continues to rotate, the locking block 4114 slides along the inclined surface 5112 and compresses the second sealing ring 52, so that the first protrusion 4113 gradually approaches the plane 5113 end of the fastener 511. When the locking block 4114 slides to the position of the plane 5113 and is located in the locking groove 5111, under the elastic restoring force of the first sealing ring 42 and the second sealing ring 52, the locking block 4114 automatically embeds into the locking groove 5111 on the plane 5113, completing the dual fixation in the axial direction (the first protrusion 4113 abuts against the plane 5113) and the circumferential direction (the locking block 4114 and the locking groove 5111 interlock), at which point the sterilization chamber is completely sealed. The inclined surface 5112 design provides a self-guiding function, which can make the locking block 4114 automatically slide into the locking groove 5111 by rotation, reducing the alignment error of manual operation and improving the efficiency of clinical use; during the sliding process of the inclined surface 5112, the second sealing ring 52 is gradually compressed and stores elastic potential energy, and finally "locks" the locking block 4114 into the locking groove 5111 through the restoring force, avoiding the problem of easy loosening of traditional buckles.

[0034] In other practical applications, refer to Figures 8 to 11 As shown, the outer wall of the lower sealing member 51 is also provided with a limiting block 513 that corresponds one-to-one with the fastener 511 and is circumferentially offset from it; when the two limiting blocks 513 of the lower sealing member 51 are facing the two hooks 411, the two hooks 411 can pass over the corresponding fasteners 511 and abut against the limiting block 513, and the second sealing ring 52 abuts against the end of the housing 3.

[0035] Specifically, each fastener 511 is also provided with a side stop 514 on its side (e.g., Figure 11 When the locking block 4114 is embedded in the corresponding locking groove 5111, the cantilever 4112 abuts against the corresponding side stop 514. Specifically, two symmetrically distributed peripheral stops 515 are formed between the two side stops 514; when the two fasteners 511 are respectively fastened to the two hooks 411, the inner and outer sides of the cantilever 4112 abut against the corresponding fasteners 511 and peripheral stops 515 respectively.

[0036] In summary, the limiting block 513 on the outer wall of the lower seal 51 is circumferentially offset from the fastener 511. During initial assembly, the limiting block 513 is aligned with the hook 411, and the hook 411 passes over the fastener 511 and abuts against the limiting block 513. At this time, the second sealing ring 52 just presses against the end of the housing 3, forming a mechanical pre-positioning before sealing. When the lower seal 51 is rotated, the limiting block 513 rotates with the lower seal 51 and disengages from the hook 411. The hook 411 moves toward the fastener 511, and the locking block 4114 slides into the locking groove 5111 along the inclined surface 5112.

[0037] After the locking block 4114 is embedded in the locking groove 5111, the inner side of the cantilever 4112 abuts against the fastener 511, and the outer side abuts against the outer stop block 515. At the same time, the tail end of the cantilever 4112 is circumferentially limited by the side stop block 514 to prevent the locking block 4114 from sliding out again after entering the locking groove 5111 due to forceful rotation by the operator. The outer stop block 515 radially limits the cantilever 4112.

[0038] The cantilever 4112 is clamped in multiple directions by fastener 511, outer stop 515 and side stop 514. Compared with single-direction limiting, it can withstand greater external impact (such as transportation vibration and operation collision) and prevent the sealing components from deforming or loosening.

[0039] At least one groove 516 is provided on the outer side of the housing of the second sealing component 5. The groove 516 can be provided on the axial outer side of the housing of the second sealing component 5 or on the bottom outer side of the housing of the lower sealing member 51. Before the sensor probe 1 is implanted into the body, the sealing member 51 needs to be removed. The lower sealing member 51 can be rotated in the opposite direction by the needle aid cover or other structure that cooperates with the groove 516, thereby removing the seal of the lower sealing member 51 on the sensor probe 1 axially.

[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.
