Description

Technical Field

[0001] This utility model relates to the field of limiting structure technology, and in particular to a limiting structure for a silicon-based sensor for blood glucose monitoring. Background Technology

[0002] Continuous glucose monitoring (CGMS) helps people with diabetes closely monitor their blood sugar and reduce the risk of diabetic complications. Unlike traditional finger-prick blood glucose meters, CGMS continuously and conveniently monitors the glucose concentration in subcutaneous interstitial fluid, creating a 24-hour continuous blood glucose profile. This accurately reflects blood glucose fluctuations under everyday environmental conditions, including nocturnal hypoglycemia and dawn phenomena that cannot be detected by conventional finger-prick blood glucose methods. A CGMS consists of a sensor and a receiver. Currently, silicon-based sensors are implanted in the arm and fixed to the upper arm with an adhesive layer to collect blood glucose data and transmit it to an app.

[0003] Although a single wear can support monitoring for up to 14 days, the silicon-based sensor may easily shift or fall off due to the patient's sleeping posture, dressing and undressing, etc., during use, which may affect the normal monitoring of blood glucose. Therefore, this application proposes a limiting structure for a silicon-based sensor for blood glucose monitoring. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that the silicon-based sensor may easily shift or fall off during use due to patients' daily activities such as dressing and undressing, which affects the normal monitoring of blood glucose. This invention proposes a limiting structure for a silicon-based sensor used in blood glucose monitoring.

[0005] The technical solution of this utility model: A limiting structure for a silicon-based sensor for blood glucose monitoring, including a fixing sticker and a silicon-based sensor, and further comprising:

[0006] A protective sleeve is set on top of the fixing sticker, the silicon-based sensor is located inside the protective sleeve, a pair of fixing blocks are fixed on both sides of the protective sleeve, a roller is set between the two fixing blocks, and a strap is set between the two rollers;

[0007] An anti-detachment limiting device is installed on the protective sleeve for reinforcing and limiting the silicon-based sensor.

[0008] Optionally, an installation strip is fixedly connected to one side of the sheath, and a sealing strip is provided on the installation strip.

[0009] Optionally, both ends of the strap are provided with Velcro, and the two Velcros are matched and glued together.

[0010] Optionally, a limiting groove is provided at the bottom of the sheath, and a slider that matches the limiting groove is connected to the bottom of the silicon-based sensor.

[0011] Optionally, the anti-detachment limiting device includes a pair of movable rods that slide through both sides of the top of the protective sleeve. The bottom ends of the two movable rods inside the protective sleeve are fixedly connected to a pressure plate. The bottom end of the pressure plate is provided with a rubber sleeve, and the top ends of the two movable rods are fixedly connected to a connecting plate.

[0012] Optionally, the bottom sides of the pressure plate are fixedly installed with locking blocks, and the bottom of the sheath is provided with a locking groove that matches the locking blocks.

[0013] Optionally, the bottom of the fixing patch and sheath is provided with an injection groove, which corresponds to the implantation part of the silicon-based sensor.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention, by setting up a protective sleeve, limiting groove, sealing strip, and injection groove, allows the silicon-based sensor to be easily placed into the protective sleeve, which is conducive to the implantation by medical personnel. The protective sleeve provides physical protection for the entire silicon-based sensor, preventing mechanical damage such as impact, scratch, or drop during wear, and extending the service life of the sensor.

[0016] Furthermore, by setting up a movable rod, connecting plate, pressure plate, and locking block, the downward pressure of the connecting plate causes the movable rod to drive the pressure plate to press down against both sides of the silicon-based sensor, and the locking block is successfully locked into the slot, thus completing the further anti-dislodgement and limiting of the silicon-based sensor, improving the stability of the silicon-based sensor implantation, and avoiding easy displacement or slippage during use.

[0017] In summary, this invention protects the silicon-based sensor while further preventing it from detaching and limiting its position, thus improving the stability of the implanted silicon-based sensor and preventing it from easily shifting or slipping out during use.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, the present invention proposes a limiting structure for a silicon-based sensor for blood glucose monitoring, including a fixing patch 1 and a silicon-based sensor 2. The fixing patch 1 also includes an attachment part, an adhesive layer, etc., and a protective sleeve 3 set on the top of the fixing patch 1. The protective sleeve 3 is made of waterproof rubber material. The silicon-based sensor 2 is located inside the protective sleeve 3. Wrapping the silicon-based sensor 2 with the protective sleeve 3 can provide daily protection for the silicon-based sensor 2. An installation strip is fixedly connected to one side of the protective sleeve 3. A sealing strip 15 is set on the installation strip. After the silicon-based sensor 2 is placed into the protective sleeve 3 and implanted, the sealing strip 15 is used to seal the protective sleeve 3.

[0031] In addition, a pair of fixing blocks 4 are fixed on both sides of the sheath 3, a roller 5 is provided between the two fixing blocks 4, a fixing post is fixedly connected between the two fixing blocks 4, the roller 5 is sleeved on the outside of the fixing post, a strap 6 is provided between the two rollers 5, and Velcro 7 is provided at the bottom of both ends of the strap 6. The two Velcro 7 are matched and glued together. Specifically, the two Velcro 7 are a female Velcro and a female Velcro. When the sheath 3 is bound to the part that needs to be fixed, the strap 6 and the Velcro 7 can be used to firmly fix the sheath 3 in the position that needs to be placed.

[0032] In addition, a limiting groove 8 is provided at the bottom of the sheath 3, and a slider that matches the limiting groove 8 is connected to the bottom of the silicon-based sensor 2. By using the slider to slide into the limiting groove 8, it is not only convenient to put in and take out the silicon-based sensor 2, but also beneficial to the limiting of the silicon-based sensor 2.

[0033] It is worth noting that the bottom of the fixing patch 1 and the protective sleeve 3 is provided with an injection groove 9, which corresponds to the implantation part of the silicon-based sensor 2. After the silicon-based sensor 2 is placed in the protective sleeve 3 and fixed, the implantation part passes through the injection groove 9, which makes it easier for medical staff to implant the silicon-based sensor 2 into the patient's epidermis.

[0034] like Figures 2-4As shown, the device also includes an anti-detachment limiting device, which is installed on the protective sleeve 3 for reinforcing and limiting the silicon-based sensor 2. The anti-detachment limiting device includes a pair of movable rods 11 that slide through the top two sides of the protective sleeve 3. The bottom ends of the two movable rods 11 inside the protective sleeve 3 are fixedly connected to a pressure plate 13. The bottom end of the pressure plate 13 is provided with a rubber sleeve. The rubber sleeve is provided to prevent the pressure plate 13 from damaging the silicon-based sensor 2 when it is pressed down.

[0035] Furthermore, the top ends of the two movable rods 11 are fixedly connected to the connecting plate 12. When the silicon-based sensor 2 is initially placed on the limiting groove 8, pressing the connecting plate 12 causes the movable rods 11 to move and press down, driving the pressure plate 13 to abut against the two sides of the silicon-based sensor 2.

[0036] Furthermore, the bottom sides of the pressure plate 13 are fixedly installed with locking blocks 14, and the bottom of the sheath 3 is provided with a slot 10 that matches the locking blocks 14. When the pressure plate 13 presses against the upper end of the silicon-based sensor 2, the locking blocks 14 are successfully inserted into the slot 10, thus completing the anti-dislodgement limit of the silicon-based sensor 2.

[0037] The working principle of this embodiment is as follows: First, the silicon-based sensor 2 is placed into the sheath 3 along the limiting groove 8. At this time, the connecting plate 12 is pressed, causing the connecting plate 12 to drive the movable rod 11 to move and press down. The movable rod 11 drives the pressure plate 13 to press down and abut against both sides of the silicon-based sensor 2. At this time, the locking block 14 is successfully locked into the locking groove 10, thus completing the limiting and fixing of the silicon-based sensor 2. Then, the sealing strip 15 completes the sealing of the entire sheath 3. After the silicon-based sensor 2 is fixed, the implanted part of the silicon-based sensor 2 passes through the injection groove 9, which makes it easy for medical staff to implant the silicon-based sensor 2 under the patient's skin. After the implantation is completed, the binding of the strap 6 and the adhesion of the Velcro 7 complete the limiting and fixing of the entire device, avoiding the displacement or falling off of the silicon-based sensor 2 during long-term monitoring, thus improving the stability of the device fixation.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
