Description

The utility model relates to the field of medicine, namely to anesthesiology and can be used in surgical practice.

The most effective utility model can be used in anesthesiology to monitor the effectiveness of anesthesia during surgery.

In addition, the utility model can find application in the practice of telemedicine, during emergency surgical operations in extreme conditions and for emergency medical care in conditions where medical sedation is necessary.

The urgency of the problem is determined by the fact that, despite the existing set of intraoperative protection devices, including safety monitoring, which allows monitoring the patient’s condition during surgery, there remains the problem of insufficient analgesia of the patient during surgery and the problem of surface anesthesia due to an incorrect assessment of the level of anesthesia effectiveness.

A device for assessing the effectiveness of anesthesia, comprising a unit for recording physiological reactions, including a module for recording a skin-galvanic reaction (RAG), a control unit with an indicator and a unit for interfacing with a computer (RF Patent No. 2269291, priority dated May 21, 2004).

A disadvantage of the known device is the use of computer programs for recording and processing RGR data from storage media - a hard disk and random access memory (RAM), which are capable of multiple write-erase, which can lead to a decrease in the reliability and degree of protection of the device when it is damaged by computer " viruses and computer

"worms", as well as the loss of medical data and a violation of the exchange of information through the interface unit.

In addition, the use of the known device does not provide for the possibility of remote evaluation of the effectiveness and management of anesthesia online, which may impair the device’s performance, as it does not allow automatic administration of anesthetics and receive additional qualified assistance from anesthetists at a remote distance from the venue anesthesia.

A device for evaluating the effectiveness of anesthesia is known, comprising an anesthetic supply unit, a physiological response recording unit, a data processing unit and a feedback control unit with an inhaled anesthesia device (US Patent No. 4,127,121 priority of 11/28/1978).

A disadvantage of the known device is the automatic control of anesthesia only in terms of oxygen concentration in the respiratory mixture, which can reduce the usability of the device, since it does not fully control and control the degree of analgesia and amnesia of the patient, since the indicator used does not reflect these psychophysiological characteristics and does not provide sufficient level of assessment of the effectiveness of anesthesia.

Another disadvantage of the known device is that during its operation does not provide automatic control of intravenous administration of anesthetics, since the device is intended for the introduction into the body of only gaseous anesthetics.

In addition, when using the known device, it is also not possible to remotely evaluate the effectiveness and control of anesthesia on-line, the absence of which can create inconvenience in its operation, since it does not allow to increase the efficiency if necessary

assessments use qualified care from medical centers remote from the site of anesthesia.

A device is known for evaluating the effectiveness of anesthesia, comprising a body, a unit for recording physiological reactions, a data processing unit, and an indication and alarm unit (Passport of the device "Rhythmocardiomonitor ELON-001 M2", CJSC Engineering and Medical Center "New Devices", Samara, 2005, 32 S., 11:00).

A disadvantage of the known device is that its use does not provide automatic control of anesthesia and the ability to remotely evaluate the effectiveness of anesthesia online, which can reduce the operational characteristics of the device, since it requires the constant participation of an anesthesiologist to monitor and control the introduction of anesthetics, which is carried out only according to its criteria subjective assessment of the effectiveness of anesthesia.

A device for assessing the effectiveness of anesthesia, containing a unit for recording physiological reactions, including modules for recording electroencephalogram (EEG) and electrocardiogram (ECG), a central processor with a data processing unit in the form of RAM and read-only memory (ROM) with processing programs and an electrical stimulation unit for evaluation muscle tone (US Patent No. 6315736 priority of November 13, 2001).

A disadvantage of the known device is that when it is used, data recording and processing occurs by repeatedly reading and writing information in the logical elements of RAM and ROM, which can lead to loss of medical data and disrupt the exchange of information due to penetration into computer processing programs of “viruses” and computer "worms" that can irreversibly damage these electronic storage media, which reduces

reliability and degree of protection of the device, as damage to data processing programs can reduce the effectiveness of anesthesia assessments.

Closest to the proposed technical solution is a device for assessing the effectiveness of anesthesia, containing a network computer with a program for automatic processing of medical data, a unit for recording physiological parameters connected to a patient, an analog-to-digital converter, random access memory for processing information, a display, a program control unit, a module with programs for administering anesthetics and a dispenser with pumps for supplying liquid and gases (US patent No. 7089927 В 2, priority from 10.23.2002).

A disadvantage of the known device is that when it is used, it is also not possible to remotely evaluate the effectiveness and control of anesthesia online, which can lead to a deterioration in the performance of the device, due to the fact that it limits the availability of efficiency assessment and control of anesthesia outside the operating room, as well as does not allow the use of the resources of remote centers of qualified anesthesiology care, which can significantly increase the level of Hb evaluate the effectiveness of anesthesia.

Another disadvantage of the known device is that during its operation, it is possible to damage the programs for administering anesthetics with computer "viruses" and computer "worms" due to changes in the program code, its modification or permanent damage, since the control programs for administering anesthetics in the program control unit are executed in in the form of storage devices with the possibility of multiple reprogramming-recording, which can reduce the level of reliability and degree of protection of the device, because if programs are damaged, the level of anesthesia effectiveness assessment may decrease.

Another disadvantage of the known device is that it is not possible to replace the permanent storage device with automatic anesthetic administration programs in the program control unit with new ones, since this is not provided for by the device design, which may lead to a decrease in its functionality.

In addition, the disadvantage of the known device is that if there is interference in the communication channel, communication and data exchange between the device units may be interrupted, which may reduce the reliability of its operation during anesthesia due to a malfunction in the control programs for the administration of anesthetics with a decrease in the quality of assessing the effectiveness of anesthesia.

The technical result of the proposed utility model is expressed:

- the ability to remotely evaluate the effectiveness and management of anesthesia online;

- to improve ease of use and expand the operational capabilities of the device;

- the ability to increase the level of assessment of the effectiveness of anesthesia, the reliability and degree of protection of the device from damage by computer "viruses" and computer "worms".

The utility model is based on the task of creating a device to improve the quality of assessing the effectiveness of anesthesia with the possibility of automated work and remote monitoring and control of the introduction of anesthetics during surgical interventions using wired and wireless communication networks.

This object is achieved in that the device for assessing the effectiveness of anesthesia contains a network computer with a program for automatic processing of medical data, a unit for recording physiological parameters connected to

a patient, an analog-to-digital converter, random access memory for processing information, a display, a program control unit, a module with anesthetics programs and a dispenser with pumps for supplying liquids and gases, and according to a utility model, a communication module for receiving and medical data transmission via wired and wireless communication networks with the ability to automatically disable remote access, while the module with anesthetics programs Cove made splittable in a permanent memory device having an array of memory cells with write-once information recording.

Thus, in the utility model, a new set of essential features is proposed. All the proposed features are significant because they affect the technical result achieved, i.e. are in a causal relationship with the specified result.

So, for example, in the preferred embodiment, a communication module for receiving and transmitting medical data via wired and wireless communication networks is additionally introduced into the device’s program control unit, which makes it possible to remotely evaluate the effectiveness and control anesthesia online, since with such design features of the device for the first time it becomes possible to control the automatic administration of anesthetics at an unlimited distance from the site of anesthesia, which allows more accurately assess the effectiveness of anesthesia as there is a possibility of additional monitoring of the procedure the introduction of anesthetics and the depth of anesthesia, and conduct anesthesia teleconference and use the online expert anesthesia care from specialized centers located at a remote distance.

It is quite reasonable that the communication module is capable of automatically disabling remote access, as a result of which, if there is interference, malfunction or failure in the communication system, it is possible to automatically transfer the device to stand-alone operation until the communication channel is restored, which increases the reliability of the device in connection with the fact that control over the administration of anesthetics and a high level of assessment of the effectiveness of anesthesia are constantly maintained.

Due to the fact that the permanent storage device is removable, it is possible to safely replace one permanent storage device with another and replace old programs with new ones, and therefore the anesthetist can use an unlimited number of programs for introducing various anesthetics and replace them in a timely manner, which increases the usability device and extends its functionality in assessing the effectiveness of anesthesia.

It is advisable that the module with programs for the administration of anesthetics is made in the form of a permanent storage device containing a matrix of storage elements with a one-time recording of information. In this regard, the reliability and degree of protection of the device is increased, due to the fact that it becomes possible to prevent damage to the device by computer "viruses" and computer "worms", since during its operation it is only possible to choose from a one-time written set of programs for administering anesthetics without any of them changes and impossibility of rewriting, which allows to increase the level of assessment of the effectiveness of anesthesia, because in programs for the administration of anesthetics, their dosage is provided by the presence of clear criteria for assessing the effectiveness of anesthesia, which are used as the limits of fluctuations of certain physiological parameters.

Thus, the distinctive features of the proposed technical solution directly affect the achievement of the technical result obtained by the implementation of the utility model.

The drawing shows a block diagram of a device.

The device comprises a network computer with a program for automatic processing of medical data (1), a physiological parameters recording unit (3), an analog-to-digital converter (4) connected to a patient (2), random access memory (5), a display (6), a software unit control (7), a module with anesthetic administration programs (8), read-only memory (9), a dispenser (10), pumps for supplying liquid (11) and gases (12) and a communication module (13).

The device operates as follows

First, one of the permanent storage devices 9 is selected with once recorded programs for administering anesthetics (for example, programs for inducing anesthesia with thiopental sodium, promedol, fentanyl, listenone, artificial lung ventilation (IVL) using a half-open type oxygen-nitrous oxide mixture in a 1: 1 ratio, halothane, isoflurane, enflurane, etc.), the dosage of which is automatically controlled by the value of physiological indicators, which are criteria for assessing the effectiveness of anesthesia, for example, respiratory rate (BH), art serial pressure, (BP), electrocardiogram (ECG), electroencephalogram (EEG), pulse oximetry (POM), plethysmography (PMG), capnometry, activity indices of the sympathetic (IAS) and parasympathetic (IAP) divisions of the autonomic nervous system, heart rate variability (HR) ), sound evoked potential (VIZ), bispectral index (LSI), etc. The selected ROM 9 is connected to the module 8 with programs for the introduction of anesthetics using the connector.

The unit for recording physiological parameters 3 using electrodes and / or pressure sensors, sound signals, etc. connect to patient 2.

Further, the gas supply pump 12 of the dispenser 10 is connected to a cylinder with a gaseous anesthetic 14, for example, nitrous oxide, which is connected to the anesthesia apparatus 15, for example, PO-6, and included in a sterile container of the pump

to supply fluid 11 of dispenser 10, the necessary amount of anesthesia is placed, for example, a solution of fentanyl in a total dose of 1.0 mg.

Then the device is turned on, and using the communication unit 13 through a wireless communication channel of the Internet using the basic TCP / IP protocol, a network computer is connected with an automatic medical data processing program 1 connected to a wired communication channel of the Internet with a program control unit 7. For operation of the device other wired or wireless communication networks (television, telephone networks, radio networks, satellite channels, fiber optic networks, etc.) can be used.

After that, the pump for supplying fluid 11 is connected to an infusion system connected to the patient’s veins or to a sterile disposable device for intravenous infusion, for example, a Sarstedt butterfly needle from Germany, which is inserted into the patient’s vein and secured to the forearm.

The initial physiological parameters are recorded in block 3, according to the electrodes connected to the patient, for example, ECG, BH, EEG, VEP. Medical data in the form of analog signals are transmitted to the input of an analog-to-digital converter 4, where they are converted to binary code. From the output of the analog-to-digital converter 4, the digitized data is input to the random access memory for storing information 5, where data is accumulated in the form of a binary code packet for a given period of time. From the output of RAM 5, the digitized data packets are transmitted via the Internet using the communication unit 13 to the network computer 1 and to the program control unit 7. In the program control unit 7, the obtained data are analyzed to automatically select the program for the administration of anesthetics, for example, halotane, promedol, sodium thiopental, fentanyl, etc., and are simultaneously displayed on display 6. Packets of information received by the network computer 1 through an automatic medical processing program

data are analyzed to control the automatic selection of anesthetics administration programs, for example, halotane, promedol, sodium thiopental, fentanyl, etc., and are displayed on its display. Further, the network computer 1 transmits via the Internet to the communication unit 13 information about the selected program for the administration of anesthetics, from which it enters the program control unit 7 for comparison. After comparison and coincidence of the anesthetics administration programs, the program control unit 7 reads and starts from the module with anesthetics programs 8 the selected anesthetics administration program, which controls the pumps for supplying liquid 11 and gas 12 of dispenser 10, which ensure the administration of anesthetics to patient 2. Upon receipt anesthetics in the patient’s body continues to register physiological parameters and their analysis by unit 3 and program control unit 7 with simultaneous display of data on display 6 and on the display of the network computer 1.

In the case of changes in physiological parameters above or below the limits defined in the selected anesthetic administration program from module 8 (i.e., changes in the data for assessing the effectiveness of anesthesia), the program control unit 7 displays information about this on display 6, transfers it to the network computer 1 and replaces one program with another by reading and loading it from a module with anesthetics programs 8. The new program controls the pumps for supplying liquid 11 and gas 12 of dispenser 10, ensuring and the introduction of anesthetics to the patient 2. When the patient reaches the required level of anesthesia, the device gives a signal about the start of surgery and displays the information "Anesthesia level is sufficient" on the displays. The cycle of automatic evaluation of effectiveness and management of anesthesia is repeated many times until the end of the surgical intervention.

In a situation of inconsistency of information about the selected programs for the administration of anesthetics, the program control unit 7 displays information about this on the display 6, issues an alarm, transmits information about the inconsistency of programs to the network computer 1 and switches to stand-alone operation. At the same time, from a networked computer, it is possible to select the program for administering anesthetics manually, which is a priority for downloading and starting the program control unit 7.

In case of violation of the communication channel due to interference or other reasons, the device is temporarily transferred to offline mode using the block automatically disable remote access 14 until the restoration of the communication channel.

In addition, the device generates an alarm signal and stops the flow of anesthetics when the physiological parameters of the patient change to life-threatening values, which are recorded in the ROM 9 and transmits information about this to the network computer 1.

In the battery mode, the device automatically selects and starts the program for administering anesthetics based on an analysis of the registered physiological parameters of the patient, the fluctuation limits of which are recorded in ROM 9 and are the criteria for assessing the effectiveness of anesthesia.

The proposed technical solution was used during surgical interventions at the Research Institute of Emergency Medicine. N.V. Sklifosovsky together with the telemedicine laboratory of the State Scientific Center of the Russian Federation - Institute of Biomedical Problems of the Russian Academy of Sciences (SSC RF - IMBP RAS), which hosted a network computer with a program for automatic processing of medical data.

Example 1 practical use of the device.

As a network computer, a laptop "ASUS A-1800" was used with a program for automatic processing of medical data, remote from the place

Recorded indicators in the form of packets of digitized data were transmitted via the Internet using a communication module to a network computer and to the program control unit. In the program control unit, the data obtained were analyzed and simultaneously displayed on the display of the device and on the display of the network computer. The program control unit reads and starts from the module with anesthetic administration programs the selected anesthetic administration program, which controls the metering pumps for supplying liquid and gas, which ensure the administration of anesthetics to the patient. As anesthetics entered the patient’s body, registration of selected physiological parameters, which are criteria for assessing the effectiveness of anesthesia, and their analysis with simultaneous display of data on the displays continued. After the patient reached the required level of anesthesia, the device gave a signal about the start of surgery and displayed the information "Anesthesia level is sufficient" on the displays, which served as the basis for the start of surgery.

During anesthesia, a communication channel violation was detected as a result of an attack by the MTU-Inform Internet service provider server by an unknown virus, but due to the effectiveness assessment and anesthesia management using the anesthetics injection program once entered into the permanent storage device, the device did not fail It was. Also during

During anesthesia, two failures were registered in the communication channel with a total duration of 6 minutes, which led to the automatic disconnection of remote access by the communication module and the transfer of the device’s operation to offline mode, after which, when the communication channel was restored, the device was automatically transferred to normal operation mode.
