CS258394B1 - Equipment for electrical stimulation of biological tissue receptors - Google Patents

Abstract

The essence of the device according to the invention is that the electrodes of the device for electrical stimulation of receptors of biological tissues are connected to the outputs of a mechanically controlled piezoelectric crystal. This eliminates the need to use for the same purpose complex, expensive and malfunctioning devices, equipped with a converter of low-voltage and high-intensity electric current to high-voltage and low-intensity electric current, connected to an assembly of electric batteries, the disadvantage of which is that they discharge quickly during operation of the device and therefore must be replaced frequently. The device is usable both as a so-called electric whip and for stimulation of biological tissues in laboratory conditions.

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for electrical stimulation of biological tissue receptors and to a high voltage source for supplying electrodes to the device for continuous operation.

Known devices of this kind are provided with a low-voltage and high-intensity electric current converter to a high-voltage and low-intensity electric current. The disadvantages of such devices are their complexity and the necessity of battery power. However, when working with the device, the batteries discharge quickly and must be replaced several times a day, which makes operation more expensive and more expensive. If these devices are equipped with electronic components, their cost increases and, moreover, they exhibit a failure rate.

These disadvantages are overcome by the solutions according to the invention. Its essence is that the electrodes of the device are connected by conductors to the outputs of a mechanically operated piezoelectric crystal. Thus, the high voltage source for the electrodes of the device, especially the tip, is a mechanically operated piezoelectric crystal. This device works on the principle of converting mechanical energy into electrical energy using a piezoelectric crystal. This is done by deforming the piezoelectric crystal, which is achieved either by increasing the downforce, exerted by a lever mechanism or the like / or by mechanical shock resulting, for example, from the release of the spring element.

The designed device is simple, unassuming, works reliably and is inexpensive as it can be assembled from common commercial parts.

An exemplary embodiment of the invention is illustrated in the drawing which is a diagram of the arrangement of the animal handling device.

In the handle 1 of the device there is a housing 2 with piezoelectric crystal 3, which is controlled by a mechanical actuator. The conductors 5, 6 of the tip electrode 7, 13 are connected to the output of the piezoelectric crystal 3.

When handling livestock, for example, driving it to a desired location, the device is applied with its tip electrodes 7, 6 to the animal body while simultaneously pressing the lever of the mechanical actuator. At this point, the piezoelectric crystal 3 transforms the mechanical energy into pulsating high-voltage electrical energy, which passes through the conductors 5, 5 to the spike electrodes T., 8. By contact with the animal body, a high voltage spark is created which shockes the animal and becomes with obedience, eg when transporting to a slaughterhouse.

The device according to the invention has a wide application in the handling of animals either as a so-called electric whip, or as an electric whip. to stimulate biological tissues under laboratory conditions.
