RU74283U1 - ECG AND REO REGISTRATION DEVICE - Google Patents

Abstract

The utility model relates to the field of medical equipment for examination by non-surgical methods and can be used for diagnostic purposes when measuring bioelectric signals of an organism or its parts. The objective of the claimed device is a significant increase in information about the functioning of the heart, which consists in registering simultaneously with the electrocardiogram (ECG) rheogram (REO). This is achieved through the use of a seven-core flat cable, namely through the alternation of its conductive wires, both signal and ground, which allows shielding of the ECG signal from interference from the signal side of the high-frequency generator.

Description

The proposed utility model relates to the field of medical equipment for examination by non-surgical methods and can be used for diagnostic purposes in measuring the bioelectric signals of an organism or its parts.

A device for registering an electrocardiogram (ECG) of a commercially available brand (catalog of IMTEH CJSC), consisting of a cable and a holder for disposable electrodes, with a plug connected to a cardiograph. This device has 2-3 leads for taking signals from the human body.

The disadvantage of this design is the need for special labeling of each cable in order to place it in a certain area on the body. In addition, long cables often become entangled with each other, so additional time is required to eliminate this drawback. In addition, there is completely no possibility of simultaneously registering an electrocardiogram (ECG) and rheogram (REO).

The essential features common with the essential features of the claimed utility model are: a cardiograph, a cable and a holder (adapter in the inventive device) connected by means of a disposable electrode to the human body.

A device is known (www / practiced.ru), consisting of a cable with ten leads, holders with plugs connected to a cardiograph, with one end of the cable connected to the connector (to the cardiograph) and the other end through the holder to a disposable electrode and to the human body .

The essential features common with the essential features of the claimed utility model are: cardiograph, cable and holders

(adapters in the inventive device) connected using disposable electrodes to areas of the human body.

Of all known devices for recording ECG, the closest to the claimed utility model is a commercially available device for recording ECG marks MS 14559 (catalog of the company Dräger medical, 2005, www.draegershop.de), consisting of a five-core round cable, each core of which is connected to its own adapter with a button connected to a disposable electrode. When the buttons are pressed, the adapters are fixed or removed from disposable electrodes connected to the human body. One out of five adapters is connected to the grounded circuit of the cardiograph, four other adapters are used to take four ECG signals from the body relative to the grounded one. All five adapters with buttons are used to remove ECG information from the human body.

The essential features of the prototype, common with the essential features of the claimed utility model, are: a cardiograph, cable, adapters connected at one end with disposable electrodes to the human body, and the other with conductive cable conductors.

The reasons hindering the achievement of the goal are that the use of only a cable, adapters and a cardiograph does not make it possible to register a rheogram simultaneously with an electrocardiogram.

The objective of the claimed utility model is a significant increase in information about the functioning of the human heart, which consists in registering simultaneously with the electrocardiogram of the rheogram.

The technical result is achieved by the fact that a high-frequency generator, a detector and an interface are introduced into the device for recording the electrocardiogram and rheogram, and the cable is a seven-core flat cable, the first and seventh wires of which are connected to the high-frequency generator, the third and fifth wires are connected to the input

cardiograph and detector input, the second, fourth and sixth conductors are connected to the ground wire of the cardiograph, and the outputs of the cardiograph and detector are connected to the interface.

To achieve a technical result, a high-frequency generator, a detector and an interface are introduced into the device for recording an electrocardiogram and rheogram containing a cardiograph, cable, adapters connected at one end to the current-carrying conductors of the cable, and the other through disposable electrodes with certain areas of the human body, and the cable, represents a seven-core flat cable, the first and seventh veins of which are connected to a high-frequency generator, the third and fifth veins are connected to the input of the cardiograph and the detector input The second, fourth and sixth wires are connected to a grounding conductor cardiograph, and outputs the cardiograph and a detector connected to the interface.

Comparing the claimed utility model with the prototype, it can be seen that it contains new features, i.e. meets the criterion of novelty. Comparing with analogues, it is seen that the proposed device meets the criterion of "significant differences", because no new signs were found in the analogues.

To prove the existence of a causal relationship between the claimed features and the achieved technical result, we consider the principle of operation of the claimed utility model.

The figure shows a diagram of a device where:

1 - high-frequency generator;

2 - cardiograph;

3 - detector;

4 - interface;

5 - the human body;

6 - adapters connected to the conductive cores of the cable.

The first and seventh conductors are connected to a high-frequency generator, the third and fifth conductors are connected to the inputs of the cardiograph and detector, the second,

the fourth and sixth veins are connected to the ground wire of the cardiograph. The outputs of the cardiograph and detector are connected to the interface.

The device operates as follows. Five disposable electrodes for an electrocardiogram are fixed on the patient’s body. Adapters from a seven-core flat cable are connected to them. The first and seventh conductors are connected to a high-frequency generator. The third and fifth veins are connected to the inputs of the cardiograph and the inputs of the detector. The second, fourth and sixth veins are connected to the ground wire of the cardiograph. A high-frequency generator through the adapters of the first and seventh cores provides a signal with a frequency of 100 kHz to the human body. Its amplitude-modulated blood flow shape is recorded by the adapters of the third and sixth veins. This signal is fed to the detector inputs, where a low-frequency envelope is selected, which is a rheogram. From the detector output, the rheogram signal is fed to the first input of the interface for visualization. Simultaneously with the adapters of the third and fifth cores, an electrocardiogram signal is taken, which is fed to the inputs of the cardiograph. From the output of the cardiograph, the signal is fed to the second input of the interface for viewing the electrocardiogram synchronously with the rheogram.

The technical and economic advantages of the claimed utility model are undoubtedly significant for medical diagnostics, since there are currently no devices that can simultaneously record an electrocardiogram and rheogram in one area of the body. This effect is achieved through the use of a seven-core flat cable, namely through the alternation of its conductive wires, both signal and ground, which allows shielding of the electrocardiogram signal from interference from the signal side of the high-frequency generator.
