Knee-jerk reflex electronic tester and method for judging knee-jerk reflex intensity

Abstract

The invention relates to the technology of medical devices, in particular to a knee-jerk reflex electronic tester. The tester comprises a diagnosis box and a sensor; the diagnosis box comprises an LED lamp, a USB power supply port, a first Bluetooth communication module, a diagnosis box switch and a microprocessor; the sensor comprises a sensor switch, a sensor charging port, a second Bluetooth communication module and an acceleration sensor; the first Bluetooth communication module is connected with the second Bluetooth communication module in a communicating mode; the LED lamp, the USB power supply port and the second Bluetooth communication module are connected with base pins of the microprocessor; the LED lamp and the USB power supply port are arranged on the outer surface of the diagnosis box; the sensor switch, the sensor charging port and the second Bluetooth communication module are connected with the acceleration sensor through a circuit board; the sensor switch is arranged on a sensor shell, and the sensor charging port are formed in the sensor shell. According to the knee-jerk reflex electronic tester, the subjective effect which is possibly caused by naked eye observation of doctors is eliminated, through a large amount of test samples, the weak, moderate and strong range of the knee-jerk reflex intensity can be constantly adjusted, and the diagnosis value is more precise.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an electronic knee jerk reflex tester and a method for determining knee jerk reflex intensity. Background technique [0002] The knee jerk reflex is one of the simplest reflexes, consisting of two neurons. The entire neural structure that performs reflexes is called the reflex arc, and generally includes five parts: receptors, afferent fibers, central, efferent fibers, and effectors. The structure of the reflex arc also varies from simple to complex. In the simplest reflex arc, afferent neurons and efferent neurons directly contact in the center, which is called monosynaptic reflex, such as the knee-jerk reflex. Complex reflex arcs have many interneurons. [0003] The afferent and efferent nerves of the knee jerk reflex are the femoral nerve, and the nerve center is the lower nerve center, located in the gray matter of the spinal cord. At the same time as...
