The invention mainly relates to the field of medical devices, in particular to an installation unit of analyte detection device.
The pancreas in a normal human body can automatically monitor the blood glucose level and automatically secrete required amount of insulin/glucagon. In the body of a type 1 diabetes patient, the pancreas does not function properly and cannot produce enough insulin for the body. Therefore, type 1 diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, there is no cure for diabetes with medical technology. The onset and development of diabetes and its complications can only be controlled by stabilizing blood glucose.
Diabetics need to have their blood glucose measured before they inject insulin into the body. At present, most of the testing methods can continuously measure blood glucose level and transmit the data to a remote device in real time for the user to view. This method is called Continuous Glucose Monitoring (CGM).
However, the protective cover of the installation unit of the current analyte detection device cannot identify whether it has been opened after leaving the factory. If the protective cover has been opened, it may pollute the sensor or auxiliary needle of the sensor and affect the user experience.

With reference to
In an embodiment of the invention, the first elastic component 1071 is in a state of compression and has elastic potential energy, and its self-elasticity gives thrust Fr to the near end of parallel slider module 103. The thrust Fr acts on the first buckle 1012 through the coupling surface of the second buckle 1033 and the first buckle 1012. And generate a component force Fsin perpendicular to the plane of the first buckle 1012, which can push the first buckle 1012 toward the outside of the housing 101 to bend, so as to release the coupling state of the first buckle 1012 and the second buckle 1033.
In the embodiment of the invention, when the installation unit 100 is used, the outer cover 1021 is rotated to break the column 10211, the protective cover 102 is separated from the housing 101, and the near end of the installation unit 100 is close to the user's skin until the fixed ring 1063 of triggering module 106 is triggered to stick to the skin surface, and the user presses the housing 101 at the far end. The housing 101 moves toward the skin, while the triggering module 106 remains stationary. Therefore, the triggering module 106 moves toward the far end relative to the housing 101, and the lug 1062 disconnects from the first slot point 10141 and enters the second slot point 10142. Meanwhile, the fixed buckle 1061 no longer contacts with the first buckle 1012. The coupling state between the first buckle 1012 and the second buckle 1033 is released due to the bending of the component force Fsin toward the outside of the housing 101.
In the embodiment of the invention, after the coupling state is released, the parallel slider module 103 continues to move toward the near end under the elastic force of the first elastic component 1071, and drives the analyte detection device 104 to move toward the near end until the lower-outer-shell 10413 of the analyte detection device 104 contacts the user's skin surface.

The thrust force of the second elastic component 1072 on the auxiliary-needle slide block 10511 is toward the far end, so the auxiliary-needle slide block 10511 can push the slide-buckles 10321 toward the outside of the housing 101, making the slide-buckles 10321 bend, the principle of which is equivalent to
In the embodiment of the invention, in the installation unit 100, the side wall of the limit slot 1015 of the auxiliary needle prevents the slide-buckles 10321 from bending, and the connection state of the slide-buckles 10321 and the auxiliary-needle slide block 10511 clasp does not change. As parallel slider module 103 and auxiliary-needle module 105 move towards the near end, the slide-buckles 10321 is separated from the auxiliary-needle limit slot 1015, and the inner wall of the auxiliary-needle limit slot 1015 no longer prevents the slide-buckles 10321 from bending. The second elastic component 1072 pushes the auxiliary-needle slide block 10511 to the far end. At the same time, the auxiliary-needle slide block 10511 pushes the slide-buckle 10321 to bend outwards, and the connection between the slide-buckle 10321 and the auxiliary-needle slide block 10511 is released. The second elastic component 1072 continues to push the auxiliary-needle slide block 10511 to move toward the far end, and finally the auxiliary-needle module 105 returns to its initial position. Auxiliary-needle 1052 retracted into housing 101 to prevent auxiliary-needle 1052 from being exposed to housing 101 and causing unnecessary damage.
In the embodiment of the invention, when the slide-buckles 10321 is detached from the limit slot 1015 of the auxiliary-needle, the semi-enclosed needle body 10522 of the auxiliary-needle penetrates the user's subcutaneous.
In the embodiment of the invention, in the installation unit 100, the T-shaped-structure slider 10351 is located in the limit slot 1013, and the limit slot 1013 restricts the position and direction of the parallel slider module 103 through the T-shaped-structure slider 10351 to ensure that the parallel slider module 103 is perpendicular to its sliding direction. Thus, the analyte detection device 104 set at the front end of the parallel slider module 103 is kept perpendicular to its motion direction, and the auxiliary-needle 1052 is kept parallel to its motion direction, so that the part of the sensor inside the auxiliary-needle 1052 and its envelope can pierce the user's skin at a vertical angle to relieve the user's pain.
In the embodiment of the invention, in the process of parallel slider module 103 sliding towards the near end, the T-shaped-structure slider 10351 slides in the limit slot 1013 until it touches the fixed ring 1063 of the triggering module 106. Driven by the first elastic component 1071, the parallel slider module 103 continues to move towards the near end. The fixed ring 1063 stops the T-shaped-structure slider 10351 from moving toward the near end, so the T-shaped-structure slider 10351 is bent around the vertical part, the T-shaped-structure buckle 10352 is disconnected from the buckle hole 10412, and the analyte detection device 104 is separated from the parallel slider module 103, so that it can be installed on the user's skin surface.
In the embodiment of the invention, when the T-shaped-structure slider 10351 contacts with the fixed ring 1063, the position of the parallel slider module 103 is a predetermined position. At this time, the lower-outer-shell 10413 of the analyte detection device contacts the user's skin surface.
In an embodiment of the invention, the auxiliary-needle 1052 passes through the second through-hole and the first through-hole 10414 in turn, and through the analyte detection device 104. Meanwhile, the semi-enclosed needle body 10522 of the auxiliary-needle 1052 envelope sensor 1042. In the process of parallel slider module 103 and auxiliary-needle module 105 moving towards the near end, the semi-enclosed needle body 10522 with sensor 1042 penetrated into the subcutaneous body. After the auxiliary-needle 1052 retracted, the internal part of sensor 1042 remained under the subcutaneous body, and the state of the internal part of sensor 1042 was not affected when the auxiliary-needle 1052 retracted.
In the embodiment of the invention, the user is required to press the housing 101 at the far end and apply force F to the housing 101 at the near end to trigger the fixed ring 1063 of triggering module 106 to contact the user's skin surface, and the user's skin provides force F′ of fixed ring 1063 that is opposite to force F, so as to realize the relative movement of triggering module 106 and housing 101. During the actual installation, the absolute position of the triggering module 106 remains unchanged, and the housing 101 moves toward the near end.
Before the installation, in order to prevent the triggering module 106 from moving relative to the housing 101, a protective cover 102 is installed at the near end of the housing 101. The protective cover 102 is surrounded by the fixed ring 1063 of the triggering module 106, so as to prevent the installation action from being carried out in an incorrect position due to the accidental collision of the fixed ring 1063.
At the same time, the auxiliary-needle 1052 and the sensor 1042 are extended into the groove of the inner cover 10233, which can play a sealing role and prevent the outside dust, particles and other dirt from contacting the needle body and the sensor and causing pollution.
In embodiments of the invention, adhesive tape is also arranged on the lower-outer-shell 10413 (not shown in the figure) of the analyte detection device to fix the analyte detection device 104 on the user's skin surface.
To sum up, the invention discloses an installation unit of analyte detection device, which comprises the shell, the protective cover and the label. The protective cover comprises an outer cover and an inner cover. The outer ring of the label is fixed on the near end plane of the outer cover, the inner ring is fixed on the near end plane of the inner cover, and the inner ring of the label is connected with the outer ring through the easy tear seam. Before using the installation unit, the outer cover and inner cover remain fixed relative to the housing. When using the installation unit, the inner cover and inner ring of label remain fixed relative to the housing, and the outer cover and outer ring of label rotate relative to the housing to damage the easy tear seam. After the easy tear seam is damaged, it cannot be restored. The user can judge whether the protective cover of the installation unit has been opened through the state of the easy tear seam, so as to avoid using the contaminated analyte detection device.
