laser stimulator

Abstract

The invention discloses a laser stimulator, which comprises a bottom plate, four universal wheels are arranged at the bottom of the bottom plate, a stimulator body is arranged above the bottom plate, and a laser is arranged on one side of the stimulator body to stimulate The side of the stimulator body close to the laser is fixedly installed with a side plate, the laser is located on the side of the side plate away from the stimulator body, a chute is opened on one side of the side plate, the top inner wall of the chute and the bottom inner wall are fixedly installed with the same A rack, a slider is slidably installed in the chute, and a horizontal plate is slidably installed on one side of the slider. The invention is convenient to adjust the position of the laser, and the laser irradiation position is accurate. By setting the motor switch in the storage slot, it can prevent accidental touch. The height of the stimulator body can be adjusted through two push rod motors, which is convenient for people of different heights. It can be used by personnel and has a shock-absorbing function, which can reduce the damage caused by vibration.

Description

technical field [0001] The invention relates to the technical field of stimulators, in particular to a laser stimulator. Background technique [0002] In the field of neurophysiology, the introduction of laser stimulators has revolutionized the study of pain. There are two methods commonly used in the past: electrical stimulation and thermal stimulation. Since nerve fibers with large diameters have a lower current threshold than those small nerve fibers that transmit pain, current stimulation will also activate these large non-pain-sensing nerves, thereby inhibiting or hindering the generation and conduction of pain signals. This requires selective activation of pain receptors. Although traditional heat stimulation can selectively activate nociceptors, it cannot generate synchronous afferent neural activity because the process of skin temperature rise is too slow. Specifically, the first method is heat conduction, which can control the stimulation temperature, but because...

Problems solved by technology

Compared with other methods that can only detect nerve density, laser stimulation can distinguish different sensory nerves such as A-δ (pain) and C (heat). For example, DEKA's laser stimulator Stimul 1340 for pain research, its principle The function of detecting the central nervous system is achieved by stimulating the A-δ and C nerves. Because the laser does not need to touch the skin, it will not stimulate the tactile sensory nerves. However, most of the existing laser stimulators are inconvenient to adjust the irradiation position of the laser. Accurately align the parts to be tested, which cannot meet people's needs
