Embodiment Construction

[0028] As mentioned above, the drive structure of the prior art drug infusion device consumes a lot of power, which increases the requirements on the power supply and has poor reliability.

[0029] After research, it is found that the cause of the above problems is that the power-on or power-off of the linear driver is completely controlled by the program unit. Since the program unit needs to respond for a long time, the linear driver takes a long time to be powered on and consumes a lot of power. .

[0030] In order to solve this problem, the present invention provides a driving structure of a drug infusion device. The first switch unit controls whether the linear driver is powered, and the timer controls the disconnection of the power supply circuit through the second switch unit to reduce the power consumption of the infusion device. .

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings...

Abstract

The invention discloses a driving structure of a medicine infusion device, which comprises a driving unit and a driving wheel, and the driving unit moves in the driving direction to drive the driving wheel to rotate; the linear driver is electrically connected with the driving unit, and the powered linear driver can pull the driving unit to move in the driving direction; the switch unit group comprises a first driving unit and a second driving unit, and the first switch unit is electrically connected with the linear driver; the power supply, the switch unit group and the linear driver are electrically connected to form a power supply circuit for supplying power to the linear driver; when the linear driver is powered, the driving unit performs driving and can trigger a first signal representing that the linear driver arrives at the end point of the driving direction, and the first switch unit is disconnected after receiving the first signal so as to cut off power supply to the linear driver; the program unit comprises a timer electrically connected with the second switch unit, the timer controls the power supply circuit to be disconnected through the second switch unit, and the power consumption of the infusion device is reduced.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a driving structure of a medicine infusion device. Background technique [0002] The pancreas in a normal human body can automatically monitor the glucose content in the human blood and automatically secrete the required insulin / glucagon. The function of the pancreas in diabetic patients is abnormal and cannot normally secrete the insulin needed by the human body. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, medical technology is still unable to cure diabetes, and the occurrence and development of diabetes and its complications can only be controlled by stabilizing blood sugar. [0003] Diabetics need to check their blood sugar before injecting insulin into their body. At present, most detection methods can continuously detect blood glucose, and send blood glucose data to remote devices ...
