Fixing device for wireless charger and wireless charging device

Abstract

A wireless charger fixing device (100, 200, 300, 400, 400', 500, 500', 500", 600, 600', 600", 700, 700', 700", 800, 800', 800"). The fixing device comprises a shoulder fixing unit (20, 20a, 20c, 20d, 20e, 20f) and a charger fixing unit (30, 30a, 30b, 30c, 30d, 30e) provided at one end of the shoulder fixing unit (20, 20a, 20c, 20d, 20e, 20f). The shoulder fixing unit (20, 20a, 20c, 20d, 20e, 20f) comprises a shaping portion (22, 22c, 22d, 22d') having a predetermined length, and the shape of the shaping portion (22, 22c, 22d, 22d') can be adjusted to extend from the chest of a human body to the back and to maintain the adjusted shape. The shoulder fixing unit (20, 20a, 20c, 20d, 20e, 20f) has a first end for the arrangement of the charger fixing unit (30, 30a, 30b, 30c, 30d, 30e) and an opposite second end. The fixing device (100, 200, 300, 400, 400', 500, 500', 500", 600, 600', 600", 700, 700', 700", 800, 800', 800") further comprises a cushioning mechanism (50, 50', 50a, 50a', 50b, 50b', 50c, 50c') provided at the first end and / or the second end, the cushioning force of the cushioning mechanism (50, 50', 50a, 50a' 50b, 50b', 50c, 50c') being smaller than the tension produced by the shaping portion (22, 22c, 22d, 22d') during opening deformation from a curved shape. By providing the cushioning mechanism (50, 50', 50a, 50a', 50b, 50b', 50c, 50c'), the tension produced by chest contraction or arm swing of a user can be absorbed without causing the shoulder fixing unit (20, 20a, 20c, 20d, 20e, 20f) to expand, thus ensuring that the position of the fixing device (100, 200, 300, 400, 400', 500, 500', 500", 600, 600', 600", 700, 700', 700", 800, 800', 800") will not change so as to cause a wireless charger to misalign with a rechargeable implantable medical device, achieving higher charging efficiency of the wireless charger.

Description

technical field [0001] The invention relates to a fixing device of a wireless charger, especially a fixing device of a wireless charger for charging a rechargeable implantable medical device, and also relates to a fixing device comprising the wireless charger Wireless charging device for the device. Background technique [0002] Implantable medical devices come in a wide variety and range of applications, such as cardiac pacemakers and spinal cord stimulators, implantable neurostimulators, and more. Most of the existing implantable medical products on the market are powered by lithium primary batteries with high energy density, and most of them have a short lifespan. In recent years, with the development of wireless technology and lithium rechargeable battery technology, the development of rechargeable implantable medical devices with longer lifespan has become the mainstream trend of future development. [0003] The implantable medical device is implanted in the patient's...

AI Technical Summary

Problems solved by technology

This portable charging device is inconvenient to wear and disassemble, and it is inconvenient for patients to use

[0005] During the use of the wireless charging fixture, due to the contraction of the chest or the swing of the user's arm, the wireless charging fixture expands, resulting in the following two problems: 1. The fixture is loose and slips; 2. The charger and the Increased distance for rechargeable implantable medical devices makes charging less efficient
