Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a fixing device for a dynamic blood glucose monitor. Background Art

[0002] Glucose monitoring is very important for diabetic patients. Through glucose monitoring, it can be determined when to inject insulin to lower the glucose level in the body, or to supplement glucose to bring the glucose level to normal.

[0003] At present, the mainstream home portable blood glucose monitors on the market (such as products produced by Sinocare, Omron, Yuyue, Roche and other companies) all use the blood sampling method of human extremity blood for testing: the user's subcutaneous tissue fluid is collected through a blood sampling pen or blood sampling test strips, and then the blood glucose level is determined by colorimetry, electrochemical methods or photometer detection. However, using a blood sampling pen or blood sampling test strips to dynamically monitor the user's blood glucose changes requires at least 4 blood glucose test strips per day, and requires at least 4 punctures of the human skin to draw blood, causing multiple stings to the user and a poor customer experience. In addition, the amount of user blood glucose information obtained by using test strips to monitor the user's blood glucose is very limited, and it is impossible to analyze and judge the user's blood glucose changes through a small amount of blood glucose information.

[0004] In addition, there is also a scheme of using electrochemical sensors for glucose detection, which directly implants the sensor into the patient's blood vessels or subcutaneous tissue. These implantable blood glucose detection devices usually need to be worn (worn by adhering to the skin) on the human body for a long time (for example, several days) to continuously monitor blood glucose data. However, these wearable dynamic blood glucose monitors often fail due to viscosity failure as the patient moves, until the dynamic blood glucose monitor becomes loose, so that the dynamic blood glucose monitor cannot work normally. Therefore, in response to the above problems, we propose a fixing device for the dynamic blood glucose monitor. Utility Model Content

Specific embodiments

[0033] The present utility model will be further described below with reference to the drawings.

[0034] Refer to Figures 1 - 11 As shown, the fixing device of the continuous glucose monitor in this embodiment includes a binding strap 1, a sliding seat 2, and a housing 3. The binding strap 1 is used to bind to the patient's arm. The sliding seat 2 is slidably assembled on the binding strap 1, and the housing 3 is rotatably connected to the sliding seat 2. The housing 3 is used to press the continuous glucose monitor.

[0035] In this embodiment, the binding strap 1 specifically includes a strap body 11, a loop buckle 12, and a plug-in component 13. The strap body 11 is made of a flexible material (such as medical rubber). A plurality of jacks 111 are provided along the length direction of the strap body 11. The loop buckle 12 is fixedly connected to one end of the strap body 11 and is integrally formed with the strap body 11. A stud hole 112 is provided at the end of the strap body 11 away from the loop buckle 12, and the stud hole 112 is used to assemble the plug-in component 13.

[0036] In this embodiment, the plug-in component 13 includes a stud 131, a first limiting protrusion 132, and a limiting piece 133. The two ends of the stud 131 are fixedly connected to the first limiting protrusion 132 and the limiting piece 133 respectively. The outer diameters of the first limiting protrusion 132 and the limiting piece 133 are both larger than the inner diameter of the stud hole 112. When assembling the plug-in component 13 in the stud hole 112, the first limiting protrusion 132 is inserted into the stud hole 112 with force, so that the stud hole 112 elastically deforms and expands in diameter. After the first limiting protrusion 132 penetrates the stud hole 112, the plug-in component 13 is assembled on the strap body 11. When it is necessary to remove the plug-in component 13, pull it in the reverse direction with force. It is worth mentioning that the outer shape of the first limiting protrusion 132 is spherical, so that the first limiting protrusion 132 can be smoothly inserted into the hole.

[0037] When the belt body 11 is bent, one end of the plug-in part 13 together with the plug-in part 13 is arranged to penetrate through the loop buckle 12 and the first limiting protrusion 132 penetrates through one of the jacks 111. In this way, the belt body 11 can be constrained into a loop and can be fixed on the patient's arm in this way. When it needs to be disassembled, the first limiting protrusion 132 can be pulled out forcefully from the jack 111. It is worth mentioning that after the plug-in part 13 is installed on the belt body 11, the first limiting protrusion 132 should be located on the side of the binding belt 1 where the housing 3 is arranged, so that the housing 3 can be located inside the loop of the belt body 11.

[0038] In this embodiment, the sliding seat 2 specifically includes a sliding sleeve 21, a rotating column 22 and a second limiting protrusion 23. The sliding sleeve 21 is sleeved outside the belt body 11, so that the sliding seat 2 is slidably assembled on the binding belt 1. The two ends of the rotating column 22 are fixedly connected to the sliding sleeve 21 and the second limiting protrusion 23 respectively. In addition, a rotating column hole 31 is opened on the top wall of the housing 3, and the rotating column 22 is rotatably assembled in the rotating column hole 31. The second limiting protrusion 23 is located inside the housing 3 to limit the rotating column 22 from withdrawing from the rotating column hole 31. In this way, the housing 3 is rotatably connected to the sliding seat 2.

[0039] During use, taking the case where the continuous glucose monitor is worn on the outside of the patient's upper arm as an example, the housing 3 is covered on the outside of the continuous glucose monitor until the inner top wall of the housing 3 abuts against the outer end of the continuous glucose monitor. Then, the binding belt 1 is tied to the patient's upper arm in the above-mentioned manner, so that the binding belt 1 applies a pushing force to the continuous glucose monitor through the housing 3 to fix the continuous glucose monitor on the patient's arm, so as to prevent the continuous glucose monitor from loosening from the patient's arm during the movement of the patient's arm and ensure the normal operation of the continuous glucose monitor.

[0040] It is worth mentioning that since the housing 3 and the sliding seat 2 are rotatably connected, when fixing some non-circular continuous glucose monitors, for example, when fixing an oval continuous glucose monitor (the corresponding housing 3 should be made oval), the attachment angle between the oval continuous glucose monitor and the patient's arm is often not fixed (here it means that the angle formed by the length direction of the oval continuous glucose monitor and the length direction of the arm is not fixed). At this time, the angle of the housing 3 can be rotated to be consistent with the attachment angle of the oval continuous glucose monitor, and then the continuous glucose monitor can be fixed. In this way, continuous glucose monitors with different attachment angles can be fixed, and various fixing situations can be handled.

[0041] In this embodiment, a plurality of limiting grooves 32 are provided on the outer side of the housing 3 facing the sliding sleeve 21, and the limiting grooves 32 are evenly distributed in a circumferential and integral column. The number of the limiting grooves 32 is an even number. In addition, on the side of the sliding sleeve 21 facing the housing 3, there are third limiting protrusions 211 that match the limiting grooves 32. The number of the third limiting protrusions 211 is two, and the two third limiting protrusions 211 are symmetrically distributed on opposite sides of the rotating column 22. The height of the third limiting protrusion 211 is 3 mm, and the axial sliding clearance of the rotating column 22 relative to the rotating column hole 31 is greater than 3 mm. Thus, when adjusting the angle between the housing 3 and the sliding seat 2, the sliding seat 2 can be pulled away from the housing 3, so that the limiting protrusion 211 exits the limiting groove 32, and then the housing 3 can rotate normally. When the housing 3 is fixed after rotating to the same angle as the continuous glucose monitor, the binding band 1 will force the sliding seat 2 to move towards the housing 3, so that the two limiting protrusions 211 are inserted into the corresponding two limiting grooves 32. In this way, the angle between the sliding seat 2 and the housing 3 can be fixed to prevent the housing 3 from being rotated by an external force and driving the continuous glucose monitor to rotate, further protecting the continuous glucose monitor.

[0042] In this embodiment, the fixing device further includes a flexible protection member 4. The flexible protection member 4 includes a first pressing pad 41, and the first pressing pad 41 is arranged on the inner top wall of the housing 3, so that the housing 3 is in flexible contact with the continuous glucose monitor, avoiding the continuous glucose monitor from being hard pressed and further protecting the continuous glucose monitor.

[0043] In addition, the flexible protection member 4 further includes a second pressing pad 42 and a ring pad 43. The second pressing pad 42 is arranged at the opening end of the housing 3 and matches the shape of the opening end of the housing 3. The ring pad 43 is fixedly connected between the second pressing pad 42 and the first pressing pad 41 and matches the shape of the inner side wall of the housing 3. This structure can prevent the opening end of the housing 3 from being in hard contact with the patient's skin, thus improving the comfort of using the housing 3.

[0044] In summary, the present utility model discloses a fixing device for a continuous glucose monitor. The fixing device can fix the continuous glucose monitor worn on the patient's arm to prevent the continuous glucose monitor from becoming loose from the patient's arm during the movement of the patient's arm, ensuring the normal operation of the continuous glucose monitor. In addition, the fixing device has multiple fixing angles and can cope with various fixing situations.

[0045] The above embodiments are only used to exemplarily illustrate the principle and efficacy of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
