Boosters for Implantable Medical Devices and Implantable Medical Systems

Abstract

An implantable medical device booster and implantable medical system are provided. The booster is used for installing the implantable medical device and the pusher and ejecting the pusher, the booster includes a pusher mounting part, the pusher mounting part includes at least two hook arms, and the radial inner side of the at least two hook arms forms the pusher The installation space is used to install the pusher, and the hook arm generally extends along the ejection direction of the pusher to form a cantilever structure whose distal end is the free end. When the force from far to near acts on the distal end of the hook arm, the The distal end moves radially outward to enlarge the pusher installation space, and the pusher can be released from or loaded into the pusher installation space. When the implantation is completed, the booster can release the push piece and install a new push piece. The booster is not a one-time item, but can be reused, and the use cost is low.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and in particular, to a booster of an implantable medical device and an implantable medical system. Background technique [0002] There are two main methods of blood glucose testing: one is to puncture the finger to collect fingertip blood, and the blood glucose test strip used for testing is used in conjunction with a blood glucose meter to collect discrete blood glucose values; the other is a dynamic blood glucose monitoring system. CGM, which implants a blood glucose sensor under the skin, the enzyme on the sensor reacts with the subcutaneous tissue fluid to detect the blood glucose value, and cooperates with the transmitter to send the blood glucose value to the terminal. This method can collect continuous blood glucose values. [0003] For the continuous blood glucose monitoring system CGM, the implant tool for implanting the blood glucose test sensor is one of the indispensa...

AI Technical Summary

Problems solved by technology

[0003] For the continuous blood glucose monitoring system CGM, the implant tool for implanting the blood glucose test sensor is one of the indispensable devices. The implant tool in the prior art often has excessive force due to human factors during use. or is too small to cause user discomfort

[0004] CN109938785A discloses an implant tool, although it obtains a uniform ejection force through the ejection spring to solve the above problems, but when triggering the ejection, it is necessary to press the button at the proximal end of the implant tool, which makes the implantation process cumbersome And the structure of the implant tool becomes complicated

When the first restraint arm constrains the second restraint arm, the needle holder is clamped by the implant tool. After the needle holder implants the needle, the second restraint arm cannot return to the inside of the first restraint arm, and the needle holder cannot return. Implants cannot be reused

[0006] Moreover, the implant tool cannot separate and recycle the used puncture needle, which also results in the implant tool being unable to be reused, and the use cost is high
