Description
Technical Field
The invention relates to an insulin pump infusion device, in particular to a refill type insulin infusion pump which can be directly installed in an insulin refill and has a more portable volume.
Background
Human intervention of physiological insulin values in diabetic patients is currently the main means for treating diabetes and other insulin deficiencies. At present, the main medicines stimulate the self-secretion and directly supplement insulin, wherein the directly supplemented form comprises injection and oral administration. An insulin pump is a major medical device for diabetes or other insulin deficiencies that automatically delivers a prescribed amount of insulin at a prescribed time, and it achieves automatic replenishment of insulin to substantially meet the therapeutic needs of the diabetic. However, the existing domestic and import insulin pumps suck insulin out of insulin pen cores, push the drug storage device into the insulin pen cores, then put the insulin into the drug storage bin, and perform air exhaust operation before normal use. In the process, the process of drawing and pushing the medicine is added once, and the risk of secondary pollution is caused. And each time changing dressing, a medicine storage device is needed, which increases the economic burden of users.

When the motor or the gear box drives the driving rod to rotate forward, the first-stage screw rod can rotate or rise along with the driving rod, and the second-stage screw rod can rotate or rise along with the first-stage screw rod; on the contrary, when the motor or the gear box drives the driving rod to rotate reversely, the first-stage screw rod can rotate or decrease along with the driving rod, and the second-stage screw rod can decrease along with the decrease or rotation of the first-stage screw rod. Wherein the pitch of the internal thread of the driving rod, the external thread of the first-level screw rod, the internal thread of the first-level screw rod and the external thread of the second-level screw rod is kept consistent, and when the driving rod is driven by the motor or the gear box to rotate for a circumference, the second-level screw rod can be precisely driven to rise or fall for a pitch.
The invention has the beneficial effects that: 1. the insulin refill can be directly loaded into the insulin refill, so that secondary pollution generated in the process of drawing out the insulin refill from the refill and loading the insulin refill into the medicine storage device is avoided; 2. the refill type insulin pump can be filled with insulin refills of different specifications and models, is convenient for users and reduces economic burden; 3. the refill type insulin pump adopts an innovative propulsion structure, so that the refill type insulin pump is smaller in size and more convenient and fast.
