RU158262U1 - SPRING ELECTRODE FOR ECG RESEARCH IN VETERINARY - Google Patents

Abstract

A spring electrode for ECG studies in veterinary medicine, characterized in that it is made in the form of a stainless steel spiral electrode, longitudinally fixed on a cuff with fasteners, while the spiral electrode itself is connected to the end of the electrocardiograph cable by means of a detachable electrical contact.

Description

The present utility model relates to the field of medical and veterinary electrophysiology. It can be used to obtain high-quality graphic recording of an electrocardiogram (ECG) in humans as well as (especially) in animals.

In medicine, various analogues and devices are used. So, for example, in patent US 2007/0149888 A1, АВВ 5/04 dated 06/28/2007, to take ECG parameters, a platform with rings for the index fingers of the left and right hand is used.

In the patent US 2006/0217620 A1, A61B 5/0402 dated 09/28/2006, 4 electrodes are used to remove the ECG, which are built into the device body, and one electrode (reference) for contact with the index finger of the left hand.

Various types of ECG sensors are also used, which are attached to the patient’s skin by means of suction cups (DE 3231491 A1 of 04/07/1983). Structurally, the closest prototype to the claimed utility model can be considered, for example, the design of an ECG electrode made in the form of a movably bendable metal strip or plate fixed to the extremities by means of fixing belts or a clothespin holder (EP 0206441 B1, from 3.06.1992 g.).

However, with regard to ECG studies in veterinary medicine, all of the above devices have disadvantages, in comparison with the device proposed in this utility model. So, for example, medical sensors on clothespin holders are suitable for fixing ECG electrodes only for animals whose diameter of the distal limb is comparable to that in humans (for example, a cow, pony, large dog breeds). Sensors on suction cups can only be conditionally -

suitable, due to the presence in animals of the coat and hair, which must be shaved before an ECG recording session. Often used in veterinary medicine, the clamping electrodes of the crocodile type also have a disadvantage associated with the pain experienced by the animals during their fixation on the skin fold. In general, all known constructions of ECG electrodes are poorly held in their position and often slide or fall during the restless movements of the animal, thereby causing interference, artifacts and the need to reinstall them, or additional fixation of the animal.

Therefore, the objective of the claimed utility model was the development of such an ECG sensor design so that when it is used, there is no displacement, reliable skin-electrode contact is provided without shaving the hair at the places of application, there is no unpleasant sensation in the animals, ease of installation and fixation and universality were observed when connecting to standardized electrophysiological equipment along with high adaptability in the conditions of anatomical differences and the size of the girth of the outer surface of course Tay animals.

The technical result of the claimed utility model is to ensure reliable contact of the electrode with the skin of the animal, the reliability of fixing the electrode on the surface of the body, ease of use.

The task and technical result are achieved due to the design features of the claimed electrode for the ECG. The spring electrode is made in the form of a spiral made of stainless steel. Such a spring electrode is longitudinally fixed (sewn) on a cuff made of synthetic material equipped with Velcro fasteners. The spring electrode is connected to the lead of the electrocardiograph via a detachable electrical contact.

In preparation for the session of registering ECG indicators in an animal, an electrolyte gel is applied to the electrode spring, which is well retained in the coil of the spring. On the distal part of the animal’s limb, the thinnest girth portion is selected, on which the electrode cuff is applied so that the turns of the pressed spring electrode penetrate the coat, forming direct electrical contact with the skin surface, after which the cuff is tightened and its position is fixed with Velcro fasteners .

Additional wetting of the skin surfaces at the points of contact with the surface of the coil-spring coils makes it possible to register bioelectric pulses without shaving the hair and coat.

The sizes of all the constituent components of the claimed electrode may vary, depending on the size of the test animal.

In relation to ECG studies in humans, an ECG electrode can be attached both to the wrists and ankles, and to the fingers and toes.

The proposed drawings and photographs show preferred embodiments of the invention:

FIG. 1 A schematic representation of a spring electrode for ECG studies in veterinary medicine is shown (side view).

FIG. 2 A schematic representation of a spring electrode for ECG studies in veterinary medicine is shown (top view).

The steel spring electrode (1) is mounted on a cuff made of synthetic material (2) and connected to the lead of the electrocardiograph (3) by means of a detachable electrical contact (4). For fixing the electrode, the cuff is equipped with fasteners (Velcro) (5).

The prototypes of the claimed device have undergone preliminary and experimental testing in an electrophysiological laboratory and veterinary clinic, on animals with various sizes

and limb shapes. Positive results were obtained in accordance with the objectives.
