Description

The utility model relates to medical equipment, namely to devices for continuous continuous monitoring of physiological parameters of a person, for example, ECG, movement, breathing, etc. and, first of all, to cardioregistrators of underwear for a long time.

From the prior art there are known technical solutions related to cardiac recorders for wearable wearing in long-term remote monitoring systems of human physiological parameters. Among these technical solutions is a device for long-term remote monitoring of physiological parameters, adapted for carrying on a person’s body, including several special wearable electrodes in the form of a flexible patch and a microprocessor-based signal conversion and processing device attached to them, with information transfer to a local wireless network and, further through traditional communication lines (Internet, GRPS, etc.) to a server for processing and storing patient data to which doctors have access; The device contains a removable battery pack and an external device for recharging it (US WO 2011077097 A1, authors D. Anderson, D. Francey, copyright holder Intelesens Ltd, 06.30.2011, A61) for supplying power supply voltage.

The disadvantage of this device is that changing the battery pack requires removing the device as a whole from the body electrodes and, thereby, interrupting the monitoring process and, accordingly, the possible loss of significant diagnostic information.

A device is known (US patent US 8332009, authors D. MacClafin, D. Anderson, copyright holder Intelesens Ltd, 12/11/2012, A61), in fact, complementing and developing the technical solution of the previous patent application. In this patent, it is proposed to integrate magnetic elements interfaced on both sides into the connection of one of the wearable special electrodes in the form of a flexible patch with the device. This allows you to provide high-quality mechanical and electrical connection and, at the same time, it is easy to disconnect the device from the electrode patch without interrupting the electrode-body contact of the patient.

However, in this patent, changing the battery pack requires disconnecting the entire device as a whole and interrupting the monitoring process, which also leads to the possible loss of significant diagnostic information.

In addition, both solutions use a set of special disposable electrodes, significantly higher in price than typical disposable electrodes.

The closest in the totality of features to the claimed technical solution are "Power device in a system for remote continuous monitoring of human physiological parameters" (patent for a utility model of the Russian Federation 142661, authors Dshkhunyan V.L., Dshkhunyan O.V., published on 06.27.2014 ), and "The system of continuous continuous monitoring of human physiological parameters" (patent for a utility model of the Russian Federation 142734, authors Dshkhunyan V.L., Dshkhunyan O.V., published on 06.27.2014). The disadvantages of this technical solution adopted for the prototype is that the cardiosensor case must be connected through a special detachable connection of at least two body electrodes, which limits the possibility of selecting a group of electrodes for the body from the standard set (R, L, F, C1-C6 , N in accordance with GOST R IEC 60601-2-51), and limits the size of the housing, due to the need to maintain a minimum distance between them (a pair of electrodes) to obtain an acceptable amplitude of the potential difference.

The objective of this technical solution is to create a miniature body design of a cardioregistrator for long-term remote monitoring with a continuous diagnostic cycle, using only one standard standard body electrode for fastening on the body with communication through the connector and cable with the other patient electrodes of the patient, and having the ability to easily change manually replace the replacement power supply unit (battery) to the backup without disturbing the continuous diagnostic cycle.

This problem is solved due to the fact that in the device for remote continuous monitoring of the physiological parameters of a person, made with the possibility of wearing on the patient’s body, containing a cardioregistrator with a single-board electronic module with a connector for the patient’s cable connected to the body electrodes, with digital conversion units removed from these electrodes analog signals, their processing, filtering, storage and transmission of information in the appropriate format to a wireless local area network, and two interchangeable units in accordance with the proposed utility model, a latch button is built into the lower plane of the cardioregistor body adjacent to the body for fastening it on one of the body electrodes, and the plane of the replaceable battery pack is tightly attached to its upper plane with an electric connector for power supply power supply based on the force of magnetic attraction created by two pairs of opposite-pole magnetic elements embedded, respectively, in the body of the cardioregistrator and unit housing of a removable battery pack, providing mechanical and electrical contact between them.

The technical result of the given set of features is a miniature and comfortable to wear flat design of the cardioregistrator case, ensuring the abutment of the lower plane to the surface of one of the body electrodes with a snap button for mechanical and electrical connections, including a single-board electronic module with conversion, processing, wireless communication to transmit digital information about the physiological parameters of the patient and with a connector for connecting via cable to the other body electrodes, which are mated by the outer plane with the flat design of the housing of the removable battery pack based on the force of magnetic attraction, due to the built-in pairs of magnetic elements providing mechanical and electrical contact, while maintaining the possibility of easily changing the battery pack manually by the patient to a backup without breaking the continuous cycle of diagnosis. The claimed utility model may be characterized in that the mating pairs of magnetic elements are distinguished by magnetic poles in order to correctly position the battery pack and the cardioregistrator.

The essence of the utility model is illustrated in figures 1. and 2.,

- pic 2 - General view (side) of the elements of the claimed device

The inventive device (Fig. 1) is mounted on the patient’s body on one of the standard body electrodes and includes a cardiac recorder 100 with an integrated single-board electronic module 400, one of the replaceable battery packs 300, a patient cable 500 connected to the other body electrodes.

In the lower plane 101 of the case of the cardioregistrator 100 (Fig. 2) adjacent to the body, a mating part (mother) 102 of the latch button 201 of the standard body electrode 200 is mounted on which the inventive device is mounted; other standard body electrodes located on the body according to the required pattern of connections (GOST 60601.2.51-2011, p. 51.101), through a patient cable 500, representing a cable of wires with end snap buttons (mother), are connected to detachable connection 401 on the built-in circuit electronic module 400.

On the outer plane 103 of the cardioregistrator case there is a case of a replaceable battery pack 300 with a group of spring contacts 302 and 402 (Fig. 2) on the mating planes 301 and 103 for power supply; usually their number is at least 2 (+, -), and for lithium batteries having a built-in current and voltage protection circuit during a charge / discharge cycle, they limit the voltage and current values to at least 3, as shown in Fig. 2. Groups of pairs of magnetic elements 104/303 and 105/304 (not shown in Fig. 1, located on the opposite side) are integrated into the case of the cardioregistrator 100 and the case of the replaceable battery pack 300, which ensure, on the basis of the force of magnetic attraction, in each pair strong mechanical contact and, accordingly, electrical contact in a detachable connection 402/302; pairs of magnetic elements 104/303 and 105/304 are distinguished by poles, which ensures correct positioning when changing the battery pack to a backup one.

The utility model works as follows.

In the initial state, before the monitoring session, standard body electrodes with snap buttons are superimposed on the patient’s body according to the required pattern of connections; the case of the cardioregistrator 100 is latched through a button 102/201 on one of the body electrodes 200; the cable loop of the patient cable 500 with end buttons is latched onto the response buttons of the remaining electrodes and connected to the plug-in connection 401 of the electronic module 400; further, one of the blocks (usually two is enough) of interchangeable power supplies 300 is mounted on the plane 103 of the cardioregistrator case, being held thereon due to the force of magnetic attraction, which provides mechanical and electrical contact in the detachable connection 402/302 to supply voltage to the electronic module 400 .

The session parameters are configured remotely from the playback equipment (smartphone, computer, or any other, by a doctor or patient) via a wireless communication channel: session time, data transmission time intervals, and other parameters; Further, a monitoring session is launched.

The analog signals from the electrodes on the patient’s body via a cable loop of cable 500 are supplied through a plug-in connection 401 and through a button 201/102 to the electronic module of the cardioregistrator 400, in which the information received is transmitted through the digital conversion, processing, filtering, storage units in the appropriate format wireless local area network. Upon reaching a lower voltage value at the battery pack 300, an audible / visual indication occurs that requires patient attention to change the battery pack 300 to a standby unit. The removal of the battery pack 300, structurally held by the pairs of magnetic elements 104/303 and 105/304 due to the force of magnetic attraction, to the backup occurs easily (with 2 fingers) for no more than 15-30 seconds, without interrupting the continuous session diagnostic cycle; the diversity of groups 104/303 and 105/304 eliminates the incorrect installation of a removable battery pack 300.

The removed battery pack goes into “recharging” mode by installing replaceable battery packs on the charging device. During a long session (several days), the change of the battery power supply to the backup one can occur repeatedly.

The technical result of the claimed utility model consists in miniaturizing the design of a cardioregistrator with a replaceable battery pack, designed for long-term wearing and using standard electrodes for registration, due to its fastening only on one of these electrodes and the use of a special magnetic detachable connection to hold the replaceable one on its outer plane battery power source.
