Reusable needle assisting device and use method thereof

Abstract

The invention provides a reusable needle assisting device and a using method thereof. The needle assisting device is internally provided with a reset mechanism capable of enabling the needle assisting device to restore to an initial locking state, and the reset mechanism comprises a needle withdrawing bin, a needle withdrawing bin knob, a trigger assembly reset button and the like. By pressing the reset mechanism, a buckle in the needle assisting device returns to an initial position, a needle withdrawing spring is compressed again, and therefore, the reset mechanism can be used for next sensor implantation. By arranging the reset mechanism, the needle withdrawing process of the needle assisting device is more stable and smoother, implantation and needle withdrawing operation can be repeatedly carried out for more times, the process of recovering the initial locking state of the needle assisting device is more stable and accurate, and dislocation and clamping phenomena cannot be generated in the process from the unlocking state to the initial locking state for more times, so that the needle assisting device and an emitter in the needle assisting device can be repeatedly used, and the needle assisting device is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a human body physiological parameter monitoring device, in particular to a reusable needle assisting device and a use method thereof. Background technique [0002] Implantable biosensors have the advantage of continuously measuring some important physiological or pathological parameters in the body that change over time, such as the concentration of oxygen, glucose, and lactic acid, so as to obtain comprehensive and accurate diagnosis or treatment effects. Continuous monitoring of human physiological parameters has important reference significance for diet, health, medication, exercise status, etc. In vitro blood glucose self-monitoring is a typical example, but because it needs to constantly prick fingers to obtain discontinuous test values, and requires users to remember the test values ​​themselves, the monitoring effect is greatly reduced. Continuous blood glucose monitoring use...

AI Technical Summary

Problems solved by technology

However, at present, most needle aids, such as blood sugar detection devices, are basically disposable medical devices in order to ensure hygiene and sterility, including needle aids and their internal transmitters, etc., which are discarded after use, and the cost of use is relatively high. It not only brings certain economic pressure to patients, but also is not conducive to environmental protection and carbon neutrality.

[0005] CN110461217A provides a needle aid, which can only be used once, and is discarded after one implantation, and there is a situation that the needle withdrawal process after implantation is easy to be stuck; CN110720930 provides a needle aid, It can be used repeatedly, but its structure is complex and requires multiple springs to cooperate. Once it is used multiple times, it is prone to inaccurate matching positions, jamming or misalignment, and it is difficult to achieve true repeated use.
