Description

Technical Field

[0001] The present invention relates to the technical field of blood glucose sensor fixing equipment, and in particular to a sensor probe fixing device for a dynamic blood glucose monitoring system. Background Art

[0002] In the field of continuous blood glucose monitoring, stable fixation of the sensor probe is crucial for obtaining accurate and reliable blood glucose data. Existing methods for fixing the sensor probe in continuous blood glucose monitoring systems often have some shortcomings.

[0003] Some fixing devices rely solely on simple adhesive tape. During daily activities, due to frequent friction between skin, clothing, and external objects, the edges of the tape can easily curl and warp, resulting in a loose fixation and prone to sensor probe displacement, which in turn affects the accuracy of blood glucose monitoring. Furthermore, some fixing devices lack effective posture stabilization measures for the sensor probe. When subjected to external forces, the sensor probe may shake or tilt, which also affects the accuracy of monitoring data.

[0004] Furthermore, some fixing devices lack breathability. Prolonged contact with the skin creates a stuffy, airtight environment, which can easily trigger allergies, itching, and other discomfort, reducing patient experience and compliance. Therefore, developing a sensor probe fixing device for a continuous blood glucose monitoring system that effectively addresses these issues is of great practical significance.

[0016] In the above-mentioned technical solution of the sensor probe fixing device of the dynamic blood glucose monitoring system, preferably: the outer section of the circular rubber strip is thinner than the inner section, which is used to reduce the thickness of the outermost side of the circular rubber strip and reduce the possibility of the outermost edge of the circular rubber strip being curled up due to friction.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0031] Example 1: This embodiment of a sensor probe fixture for a dynamic blood glucose monitoring system primarily comprises a blood glucose sensor 1, a sensor-securing tape 2, an anti-warping adhesive tape 3, and a sensor-stabilizing strap 4. A monitoring probe for piercing human skin is provided on the bottom surface of the blood glucose sensor 1. The outer side of the bottom surface of the blood glucose sensor 1 is fixedly connected to the inner top area of a ring-shaped medical tape 21. Within the sensor-securing tape 2, the bottom surface of the ring-shaped medical tape 21 is coated with a layer of medical adhesive for adherence to the skin. The tape has 120 ventilating pores 23, a monitoring opening 22 at its center, and a chamfered inner edge. The outer surface of the monitoring opening 22 is provided with six arc-shaped openings arranged in a circular array centered on the central axis. The bottom surface of the annular adhesive strip 31 of the anti-warping adhesive tape 3 is coated with medical adhesive material. The inner side of the bottom is adhered to the outer side of the top of the annular medical tape 21, and the outer side of the bottom is adhered to the skin. Its surface is provided with 100 breathable openings 32, and the outer side of the top surface is provided with a slope 35. The outer section is thinner than the inner section, and the inner side wall is provided with a notch 33 for the bandage 41 to pass through.

[0032] The four bandages 41 of the sensor posture stabilization strap 4 are arranged in a circular array. Their distal ends are fixedly connected to legs 42, which are fixedly connected to the top of the annular medical tape 21 via Velcro. At their convergent ends, the bandages 41 are fixed to a silicone disc 45. The bottom of the silicone disc 45 is fixedly connected to an airbag 44, which has a cavity 43 within it and multiple anti-slip grooves on its bottom surface. During use, the annular medical tape 21 is first adhered to the skin using the bottom medical adhesive, aligning the monitoring opening 22 with the appropriate position. The outer bottom edge of the blood glucose sensor 1 is then secured to the inner top edge of the annular medical tape 21. The inner bottom edge of the annular adhesive strip 31 is then attached to the outer top edge of the annular medical tape 21, and the outer bottom edge is then attached to the skin. Finally, the bandage 41 is secured to the top of the annular medical tape 21 via legs 42. The airbag 44 contacts the top surface of the blood glucose sensor 1, providing a slight pushing action through the cavity 43 to prevent displacement of the blood glucose sensor 1.

[0033] Example 2: The sensor probe fixing device for the dynamic blood glucose monitoring system of this embodiment has the same components as those of Example 1. The monitoring probe at the bottom of the blood glucose sensor 1 penetrates the human skin and is fixed to the inner side of the top of the annular medical tape 21. The annular medical tape 21 of the sensor fixing tape 2 has a medical adhesive material at the bottom, 100 breathable pores 23 on the surface, a monitoring opening 22 in the center with a rounded chamfered edge, and 8 arc-shaped openings in a circular array on the outside. The annular adhesive strip 31 of the anti-warping adhesive tape 3 has a medical adhesive material at the bottom, adheres to the annular medical tape 21 and the skin, has 80 breathable openings 32 on the surface, a slope 35 on the outside of the top, the outer section is thinner than the inner section, and the inner sidewall has a notch 33. The sensor posture stabilization strap 4 comprises four bandages 41 arranged in a circular array. One end has a foot 42 secured to the top of the circular medical tape 21 via Velcro. The other end converges on a silicone disc 45. The disc 45 has an air pocket 44 at its base, which has a cavity 43 and anti-slip ridges. During installation, the circular medical tape 21 is adhered to the skin in an appropriate location. The blood glucose sensor 1 is then secured to the tape, followed by the annular adhesive strip 31. Finally, the bandage 41 is secured, leaving the air pocket 44 in contact with the top surface of the blood glucose sensor 1, stabilized by the cavity 43 and anti-slip ridges.

[0034] Example 3: The sensor probe fixing device for the dynamic blood glucose monitoring system of this embodiment has similar component structures to those of Examples 1 and 2. The monitoring probe at the bottom of the blood glucose sensor 1 penetrates the skin and is fixed to the inner side of the top of the annular medical tape 21. The annular medical tape 21 of the sensor fixing tape 2 has a medical adhesive material at the bottom, 160 breathable pores 23 on the surface, a central monitoring opening 22 with a chamfered edge, and four arc-shaped openings in a circular array on the outside. The annular adhesive strip 31 of the anti-warping adhesive tape 3 has a medical adhesive material at the bottom, adheres to the annular medical tape 21 and the skin, has 120 breathable openings 32 on the surface, a slope 35 on the outside of the top, the outer section is thinner than the inner section, and the inner sidewall has a notch 33. The sensor posture stabilization strap 4 comprises four bandages 41 arranged in a circular array. One end has a foot 42 secured to the top of the circular medical tape 21 via Velcro. The other end is connected to a silicone disc 45. The disc 45 has an airbag 44 at its base, which has a cavity 43 and anti-slip ridges. During operation, the circular medical tape 21 is first affixed, securing the blood glucose sensor 1. The annular adhesive strip 31 is then affixed, and the bandage 41 is finally secured. The airbag 44 stabilizes the blood glucose sensor 1 through the cavity 43 and anti-slip ridges.

[0035] According to the content of the above-mentioned preferred technical solution, the workflow of this technical solution is explained as follows: first, the skin at the installation site is cleaned and disinfected, and then the medical adhesive on the bottom surface of the annular medical tape 21 of the sensor fixing tape 2 is brought into contact with the cleaned skin and appropriate pressure is applied to make the annular medical tape 21 firmly adhere to the skin. Since the surface of the annular medical tape 21 is provided with multiple breathable pores 23, the breathability of the skin at the adhesion site can be ensured, reducing the stuffy and uncomfortable feeling. At the same time, the multiple arc-shaped openings provided on its outer surface also play a certain breathable role, and these openings may increase the flexibility of the annular medical tape 21 to fit the skin to a certain extent; then, the monitoring probe at the bottom of the blood glucose sensor 1 is inserted into the human skin, and at the same time, the outer side of the bottom surface of the blood glucose sensor 1 is fixedly connected to the inner area of the top surface of the annular medical tape 21. At this time, the blood glucose sensor 1 is located above the monitoring opening 22 opened in the central position inside the annular medical tape 21. The arc chamfering treatment of the inner edge of the monitoring opening 22 can avoid scratching and damage to the blood glucose sensor 1 or the skin.

[0036] Then, the inner side of the bottom surface of the circular adhesive strip 31 of the anti-warping adhesive tape 3 is adhered and connected to the outer side of the top surface of the annular medical tape 21, and at the same time, the outer side surface of the bottom of the circular adhesive strip 31 is adhered and connected to the human skin. The multiple breathable openings 32 opened on the surface of the circular adhesive strip 31 can further ensure the breathability of the adhesion part. The slope 35 opened on the outer side of its top surface can reduce the stress concentration caused by friction with external objects, and reduce the possibility of curling and warping. The design that the outer section of the circular adhesive strip 31 is thinner than the inner section further reduces the risk of curling and warping of the outermost edge due to friction, and the notch 33 opened on the inner side wall of the circular adhesive strip 31 provides space for the subsequent installation of the sensor posture stabilization strap 4.

[0037] Finally, the sensor posture stabilizing strap 4 is installed. The legs 42 fixed to the ends of the four bandages 41 that are away from each other are fixed to the top surface of the annular medical tape 21 through Velcro. The ends of the bandages 41 that converge are fixed on the silicone disc 45. The airbag 44 fixedly connected to the bottom surface of the silicone disc 45 contacts the upper surface of the blood glucose sensor 1. The cavity 43 opened inside the airbag 44 will be slightly deformed when subjected to a certain pressure, thereby providing a slight pushing effect on the blood glucose sensor 1 towards the human body. When external objects rub against the blood glucose sensor 1 or the fixing device, the pushing effect of the airbag 44 can prevent the blood glucose sensor 1 from shifting due to friction. At the same time, the multiple anti-slip grooves arranged on the bottom surface of the airbag 44 can increase the friction with the upper surface of the blood glucose sensor 1, further enhancing the fixing effect of the blood glucose sensor 1. Through the above series of operations, the installation of the sensor probe fixing device of the dynamic blood glucose monitoring system is completed, so that the blood glucose sensor 1 can be stably fixed on the human skin, thereby performing normal blood glucose monitoring.
