Definitions
- the present invention has its preponderant field of application in safety practices and protocols in the Mining Industry, specifically where activities are carried out in confined spaces with a risk of poisoning due to the presence of Carbon Monoxide in the environment.
- Carbon monoxide (CO) is an invisible, odorless, colorless, tasteless, flammable and highly toxic gas, which is released when combustible materials are burned incompletely or with little oxygen supply.
- This gas comes from materials such as wood, charcoal, mineral coal, tobacco, natural gas, diesel, kerosene, gasoline, butane and propane. Its characteristics make it very difficult to detect with the senses of the human body, being the first and most frequent warning symptoms that indicate the presence of CO in the air, usually headaches, dizziness, nausea, vomiting and muscle weakness. This gas can even cause the death of a living being when you breathe even in moderate amounts, by poisoning in a few minutes, because it replaces the oxygen in the blood hemoglobin.
- CO binds to hemoglobin in a way up to 250 times more easily than with oxygen itself.
- the compound called COHB or carboxyhemoglobin is produced, which is about 200 times more difficult to separate than the hemoglobin compound with oxygen. It blocks the ability of blood to transport oxygen and results in a serious injury to the lung and brain, even causing death.
- gases especially carbon monoxide, these are generated by the conditions of mineral extraction such as the use of internal combustion machines.
- Tools are required that have the ability not only to detect and Inform the value of CO in real time to the control system, but have algorithms that estimate the conditions of the workers without the need for invasive sensing means, in order to establish specific evacuation procedures if required.
- the present invention solves said problem and aims to estimate a percentage of COHB in the blood; It is based on a non-invasive method that integrates CO measurement sensors and time detection and measurement to which the miners are exposed.
- Patent No. EP0860142 claims an improved method and apparatus for photoplethysmographic monitoring of blood analyte parameters, specifically oxyhemoglobin, deoxyhemoglobin, COHB and methemoglobin, utilizes a plurality of light beams that have different spectral contents to illuminate a patient's tissue . It is used in the forward calibration equation to generate estimated values of relative blood analyte concentration.
- Patent No. US6397093 describes an apparatus and method that allows the non-invasive monitoring of the COHB level of a subject, thus allowing the detection of a possible carbon monoxide poisoning.
- Patent No. UA2005012309 refers to medicine, in particular a method for the non-invasive determination of the relative concentration of COHB in arterial blood that is calculated by the formula using certain regression coefficients of selected intervals of logarithmic signal values. luminous that pass through bio-store with variable blood flow and measured Three wavelengths and absorption coefficients of deoxyhemoglobin, oxyhemoglobin and COHB. The following is a brief description of current patents in relation to the subject of gas detection in mining, in order to complement the references of the present invention. Patent No.
- US20150163652 claims a system and method of monitoring of gases in mining, the method of the invention includes the collection of data emitted by the nodes to monitor the percentage of gas in the environment, if the gas passes over a preset threshold a visual alarm is generated and audible.
- patent No. CN 102733855 details a mobile gas monitoring system in an underground coal mine.
- the system comprises a mobile gas detector brought by people to detect the gas concentration, a radio communication base station arranged on the surface to receive information on the gas concentration detected by carrying out a radio communication with the gas detector mobile, a monitoring center server used to receive the information of the detected gas concentration and position information of the mobile gas detector from the radio communication base station to carry out the information management.
- Figure 1 is a diagram of the inputs and outputs of the Method of Estimation of Alert and Awareness Status in relation to the percentage of COHB in Blood, corresponding to the present invention.
- Figure 2 is the representative diagram of the database that uses the State Estimation Method of Alert and Awareness in relation to and awareness of people detected in a confined space.
- At least one sensor measures the level of ambient CO [101] in real time; if said value exceeds an allowed limit [104] then an output [105] is generated that activates a visual and / or auditory alert, in addition send such information to the main security system! of the company.
- the CO sensor input [101] the exposure time of people to said CO level [103] through at least one sensor are taken into account of presence and is compared to a database with default values [106]; the output of said algorithm [107] will determine an action corresponding to issuing a visual alert, an evacuation route indication or requesting assistance from a security brigade.
- Figure 2 shows the diagram with data corresponding to the database of the method of the present invention.
- the literature indicates that in 10% of COHB there is a slight headache and fatigue. In 20% of COHB in the blood the headache becomes more acute and nausea occurs. At 30% COHB drowsiness occurs, until 40% is reached where the person fades away. A 50% level of COHB in the blood represents permanent damage to the brain and even death. This information is essential for the functionality of the Method of Estimation of Alert Status and Consciousness in relation to the percentage of COHB in Blood of the present invention.

Abstract
La présente invention concerne un procédé d'estimation de l'état de vigilance et de conscience en relation avec le pourcentage de carboxyhémoglobine (COHB) dans le sang de personnes qui travaillent dans des espace confinés et sont exposées à des intoxications au gaz monoxyde de carbone (CO). Ce procédé fait appel à des capteurs de CO et des capteurs de présence pour détecter des personnes exposés à des niveaux dudit gaz dépassant les limites autorisées. Un système intégré comprenant lesdits capteurs exécute un algorithme d'estimation du niveau de COHB dans le sang en utilisant une base de données prédéterminée pour comparer les valeurs à celles qui ont été obtenues.
