Definitions

  • the present invention relates to a dive computer comprising means for checking the diver's biometric parameters, that is to say, means which in addition to the normal information usually detectable, also provide a function not normally present, which is extremely useful if not essential: the processing and/or displaying of the measurement of the physical/chemical/biological parameters of the diver's bloodstream.
  • the present invention relates to a dive computer able to read and process physical/chemical/biological parameters in the bloodstream such as:
  • the dive computer in accordance with the present invention can guarantee much greater safety for the diver during a dive because it can check and report on risks linked to:
  • the present invention is for use in the field of measuring instruments and in particular in the sector of instruments which may be worn on the wrist or may be portable, for sportsmen and women and in particular for diving.
  • dive computers In the diving sector there are various measuring and checking apparatuses and instruments, called dive computers, which can be worn on the wrist or located on the end of control hoses or in any other most suitable position.
  • a dive computer is an instrument used to measure various parameters during a dive, typically the dive time and depth, to allow calculation of the times for safe ascent to the surface without the well-known problem of the bends.
  • the bends are a pathology deriving from the formation of bubbles in the bloodstream or tissues and caused by failure to eliminate inert gases, such as nitrogen, following a dive.
  • dive computers are designed to process decompression table data and can continuously estimate the partial pressure of the inert gases in the body, in particular nitrogen, based on continual reading of the diver's depth and the dive time.
  • Many dive computers also provide the diver with other information, for example the water temperature, the pressure of the gas in the cylinder or average air consumption, being real battery-powered computers enclosed in a watertight shell.
  • All dive computers measure the surrounding pressure to calculate the partial pressure of the gases in human tissues.
  • the most advanced models also include further information such as the water temperature or the pressure inside the cylinder.
  • Some dive computers even use an elastic strap on the diver's chest which, with special electrodes, detects the heart rate during the dive.
  • Prior art dive computers use the dive profile and with a mathematical algorithm estimate the partial pressure of the inert gases which must be expelled from the tissues. Based on these calculations, the computer estimates the possibility of direct ascent to the surface or, rather, ascent to the surface with one or more decompression stops.
  • Some algorithms used are the Buhlmann algorithm, the Multi-Tissue Model, the variable permeability model and, often, the Reduced Gradient Bubble Model (RGBM).
  • RGBM Reduced Gradient Bubble Model
  • Some computers can calculate the decompression stops even for gases other than air, such as nitrox, pure oxygen, trimix, helium and other mixtures.
  • common dive computers are mainly designed to provide data about the problem dealt with in decompression tables, therefore based exclusively on the estimate of the partial pressure of inert gases in the body, in particular nitrogen, processing and supplying data only about the problem linked to the bends.
  • This technological limit of conventional dive computers does not allow the detection of risks linked to the various physiological factors, such as hypoxia, that is to say, haemoglobin oxygen saturation, hyperoxia, that is to say, the quantity of oxygen dissolved, hypercapnia, that is to say, the quantity of CO2 dissolved, and does not even allow measurement of fatigue, thus each year there are several cases of divers who are taken ill, in some cases their condition being serious and often unfortunately lethal.
  • hypoxia that is to say, haemoglobin oxygen saturation
  • hyperoxia that is to say, the quantity of oxygen dissolved
  • hypercapnia that is to say, the quantity of CO2 dissolved
  • the present invention has for an aim to provide a dive computer comprising means for checking the diver's biometric parameters which is able to eliminate or at least reduce the above-mentioned disadvantages.
  • the invention also has for an aim to provide a dive computer comprising means for checking the diver's biometric parameters, and which consists as a whole of an apparatus designed for reading the diver's biophysical parameters and an apparatus able to process said data.
  • the apparatus for reading biophysical parameters and the data processing apparatus may be grouped together in a single device, or they may remain as separate components which may be connected to each other using a cable or a wireless system, that is to say by means of radio waves or the like.
  • a dive computer comprising means for checking the diver's biometric parameters whose features are described in the main claim.
  • the dive computer can warn the diver visually or acoustically and if necessary will be able to activate special solenoid valves designed to modify the diver's buoyancy.
  • the device disclosed therefore substantially consists of an apparatus designed to read the diver's biophysical parameters and an apparatus able to process said data.
  • the computer uses technologies for reading data such as:
  • the device comprises at least one biometric signal pick up element and at least one signal processor.
  • the various new data processed by the dive computer again coinciding with reading of the depth (water pressure) and the dive time, is managed by a dedicated software which confirms precise information for the diver regarding oxygen saturation, informing the diver of any danger of hypoxia, the quantity of oxygen dissolved, with any danger of hyperoxia, the quantity of CO2 dissolved, with any danger of hypercapnia, the diver's fatigue level and supplies a very precise estimate of the danger of suffering the bends.
  • this invention aims to make the diver's dive safer whether he or she is using an open-circuit scuba set (classic demand regulator), or a closed-circuit (use of rebreather), free diving or other.
  • the dive computer in accordance with the invention substantially consists of a data acquisition part 10, for example made using a watertight material casing and also able to resist underwater pressure, this acquisition part being connected, by a cable 11, or by means of a wireless or other most suitable system, to at least one sensor 12, designed to read biometric parameters, which can be applied to a part of the body sensitive to the data to be detected, and it also consists of a part 20 for processing the data received.
  • the data acquisition part 10 of the computer may, for example, be applied on the elastic strap 13 of a diving mask 14 and secured there using a clip 23 on the elastic strap.
  • the cable 11 connects the computer 10 to a group of luminous sensors and gas or chemical sensors, which are connected to the earlobe 19 for example using fixing clips 15.
  • the connecting cable 11 connects the battery container 16 and the reading circuit 17 with the actual sensors 18 designed to read the biometric parameters.
  • the group of sensors 12 is secured, by clips 15 to the earlobe 19, which is a particularly vascularised part of the body, but the sensors may be applied in the same way to other parts of the body, for example on one or more fingers, as illustrated in Figure 7 .
  • the sensors normally used are two light sources at different frequencies 18 which, passing through the vascularised part of the skin, for example the earlobe 19, detect colour variations which indicate haemoglobin saturation.
  • a heating element and an optical and chemical pick up element is normally used to detect the partial CO2 pressure.
  • An electrode is generally used to detect the partial 02 pressure, whilst the heart rate is detected by the volumetric variation linked to the arterial pulse.
  • the rechargeable battery is located in the container 16 which is watertight.
  • An adjacent watertight container holds the electronic circuit 17 designed to transmit the biometric data to the processor 20, located on the diver's wrist, or at the end of the compressed air hose 21.
  • the numeral 22 denotes cavities for the electronic circuits dedicated to the biometric sensors.
  • the system described therefore uses the acquisition unit 10 with the sensors 12, and the processing and if necessary display unit 20 of the dive computer to read and process the physical/chemical/biological parameters in the bloodstream, such as:
  • the dive computer consisting of the acquisition unit 10 with the sensors 12, and of the processing and if necessary display unit 20, is therefore able to guarantee much greater safety for the diver during a dive because it can check and report on risks linked to hypoxemia and hypoxia (haemoglobin oxygen saturation), hyperoxia (quantity of oxygen dissolved), hypercapnia (quantity of CO2 dissolved), fatigue (analysed by interpolation of the biometric data analysed by the dive computer).
  • the sensors used for reading the above-mentioned data also provide very precise readings of the heart rate, obtained from the variation in volume linked to the arterial pulse, very useful for calculating the quantity of air actually breathed and the diver's level of fatigue.
  • the system disclosed allows the diver's dive to be made safer whether he or she is using an open-circuit scuba set (classic demand regulator), or a closed-circuit (use of rebreather), free diving or other.
  • sensors of any type may be used, such as those to be applied on the fingers, shown in Figure 7 , or other kinds of sensors suitable for the purpose.
  • the apparatus for reading biophysical parameters 10, 12 and the data processing apparatus 20 may be grouped together in a single device, or they may remain as separate components which may be connected to each other by a cable or through a wireless system, that is to say by means of radio waves or the like.
  • versions of the computer may be made in which programs and detectors even with partial functions are installed, that is to say comprising systems for detecting only one or several of the physical/chemical/biological parameters of the bloodstream, that is to say, haemoglobin oxygen saturation and/or partial CO2 pressure, and/or partial 02 pressure and/or the heart rate.
