    专利说明:

    The invention relates to a system and a method for monitoring the consumption of gas, in particular oxygen (O2), medical air or nitrous oxide (N20), of one or more patients within a hospital building, the gas being supplied by the network of gas pipes of said hospital building.
    In hospital buildings, such as hospitals, clinics or others, medical gases, in particular oxygen (02), medical grade air or "medical air" and nitrous oxide (N20), are usually routed by a network of gas pipelines from one or more gas sources, such as gas reservoirs or storage, on-site gas production units, such as adsorption oxygen production units with PSA pressure variations ( Pressure Swing Adsorption) or Vacuum Swing Adsorption (VSA) or others, to their site of use, namely in patient rooms, treatment rooms, operating rooms or the like. The extraction of gas from said network is done by means of gas distribution sockets which are generally fixed to the walls, in particular to the walls of hospital buildings. They are commonly called "wall outlets". An example of a wall outlet is given by EP-A-2306060.
    The problem is to be able to monitor or measure the gas consumption of a specific patient supplied with gas by such gas distribution outlets.
    In fact, knowing the consumption of a patient, and therefore the gas flow rate passing through a given gas distribution outlet supplying said patient for a period of time, not only ensures that the patient inhales the right gas and the good quantity that he needs within the framework of his treatment, for example an oxygen therapy treatment, but this also makes it possible to determine the cost of gas treatment for a given patient resulting in a new form of administrative and accounting management of the care pathway . In addition, the consumption of gas linked to a wall outlet must make it possible to better manage the gas supply to the hospital building, in particular stocks or gas production, so as to avoid supply shortages or, conversely , unnecessary supplies. It must be possible to monitor gas consumption continuously or almost continuously throughout the day.

The invention will now be better understood thanks to the following detailed description, given by way of illustration but not limitation, with reference to the appended figures in which Figures 1 to 6 schematize several embodiments of a system for monitoring the consumption of gas according to the present invention.
    FIGS. 1 to 6 represent several embodiments of a gas consumption monitoring system according to the present invention, which comprises a gas distribution outlet A fluidly connected to a gas pipeline or pipe arranged in a hospital building, that is, the hospital's gas network. This gas distribution socket is here a wall socket A making it possible to supply gas, for example oxygen or medical air, to a patient P.
    A gas distribution socket A or "wall socket" can be installed either in a technical sheath, for example a hospital headboard, or protruding on a wall or wall, or in a ceiling arm supporting for example lighting in a treatment room. The gas distribution outlet A is therefore an element of a medical gas distribution system, on which the operator can connect or disconnect one or more devices, such as flexible gas pipes or the like, serving to supply gas. medical device (s), such as anesthesia machines, lung ventilators, or any other type of medical device.
    The gas consumption monitoring system according to the present invention also comprises a gas flow measurement system arranged to measure the flow of gas delivered by the gas distribution outlet A to said patient P, for example a flow meter, advantageously a fluidic oscillation flowmeter, and moreover a telecommunication system, which is here wireless, configured to transmit, preferably wirelessly, the gas flow value measured either directly to a computer data processing system E, such as a server cloud or other type, or either indirectly via a patient data transmission device C, such as a smart phone (ie, smartphone), a digital tablet or the like, or both, as illustrated in Figure 2. It should be emphasized that the gas flow measurement system and the patient data transmission device C can be integrated into the wall outlet A.
    In the case of an indirect transmission, said patient data transmission device C receives a signal representative of the gas flow (ie flow value) measured by the gas flow measurement system and retransmits this signal representative of the gas flow to the data processing computer system E, as illustrated in FIG. 1. When a fluidic oscillation flowmeter is used to determine the gas flow rate, said flowmeter will measure one (or more) oscillation frequency which will then be converted into flow value.
    In general, the patient data transmission device C also makes it possible to transmit one or more patient data, such as an identification of the patient ID, to the data processing system E.
    One or more patient data can also be introduced or validated in the device C for transmitting patient data by a member of the nursing staff PS, in particular a nurse or the like, as illustrated in FIGS. 1 and 2 for example. In particular, the nursing staff member PS could validate that the gas flow information collected by the device C for transmitting patient data corresponds well to the patient P located in the room equipped with the wall outlet A considered, that is to say ie that for which the gas flow rate was measured and transmitted to the data transmission device C. Moreover, so that the measured gas flow rate is associated with the patient P having inhaled the gas considered, it is imperative to provide moreover, data pairing means configured to pair, that is to say associate, the value of the measured gas flow rate and the patient data or data, in particular its identification ID.
    In FIG. 1, the data pairing means are directly integrated into the patient data transmission device C so that the data pairing takes place before the data is transmitted to the computerized data processing system E, such as a server, that is to say that the data processing system E receives data previously and already paired.
    In the embodiment of Figure 2, data pairing means are directly integrated into the patient data transmission device C as in Figure 1, but other data pairing means are also delocalized in an antenna -delay D or the like communicating with the data processing computer system E. The paired data therefore arrive at the data processing computer system E by two different channels or channels.
    Alternatively, in FIG. 3, data transmission is provided, on the one hand, by the socket A and, on the other hand, by the device for transmitting patient data to the computer data processing system E at within which the pairing of said data is carried out.
    Alternatively, in Figure 4, the data pairing means are directly integrated into the wall outlet A. The information is therefore paired there before being sent to the computer server E or the like, via a relay antenna D or the like. In this case, the patient identification or other patient information comes from a patient data transmission device which is of the connected bracelet type B.
    According to other alternatives visible in Figures 5 and 6, the data travels via a local relay R while being previously paired (Fig. 6), as explained above, or then unpaired (Fig. 5), the pairing taking place in the computer server E or the like. The apparara is then done by geolocation and detection of the elements in a close geographical space.
    In the embodiment of FIG. 6, the distribution outlet A can search for the connected bracelet B, recognize it and then send it its data, that is to say at least the gas flow rate. The bracelet will then link its data to that (s) of socket A, before sending it to the server E after pairing, for example in bracelet B, the sending being done directly or via a relay antenna D or via a local relay R (Fig. 5). A reverse diagram would also be possible, that is to say that the data could transit and be paired within the wall socket A (see Fig. 4). In general, the gas consumption monitoring system of the invention is configured to perform a measurement and collection of the flow of medical gas delivered by the wall outlet A and administered to a patient P via said wall outlet A , then to transmit the information, in particular the measured gas flow rate and the identification ID of the patient P, to a remote computer system E.
    The gas flow measurement system, such as a flow meter, used to collect the flow of medical gas administered to patient P, as well as the telecommunications system, preferably wireless, can be placed upstream or downstream of the wall outlet. A or even integrated into said wall outlet A. The telecommunication system is preferably wireless and comprises, for example, a modem and a transmitting / receiving antenna.
    The information collected by the gas consumption monitoring system according to the present invention can be, in addition to the identification (ID) of the patient which is essential information, also an identification (IDS) of the system, the autonomy of the battery. of the system, its next maintenance date, the type of gas delivered by the wall outlet, its location in the hospital, the environmental temperature, the time of use, the pressure measured, the temperature measured ...
    The system can also perform calculations with the information collected, in particular the flow rate value, such as calculating the total consumption of gas administered over a given period of time for example. These calculations can be done in particular in the data transmission device C, in the server E or the like, or even in an electronic card integrated into or cooperating with the wall outlet A.
    The transmission of information can be done at long range, ie "long range", via a network of Lora type, wifi or Sigfox for example, or at short range, ie "short range", via a network of Bluetooth Low Energy type for example. Thus, the communication with the relay antenna D or the like or with the server E, or even with the local relay R (FIGS. 5 and 6) is done by long-range or short-range transmission, and the same goes for same as that between the wall socket A and the data transmission device C.
    The gas consumption monitoring system according to the present invention can also receive information from the remote computer system E, such as a server or the like, including of the “cloud” type, and moreover transmit and receive information in communicating with various external devices, in particular a relay system, such as a relay antenna D. Likewise, the patient data transmission device, for example a connected bracelet B, can also receive information from the remote computer system E.
    It is therefore understood that the exchange of data between the communicating wall socket A and the computer system E, that is to say a server or the like, can be done directly or indirectly through another system, for example via the device. transmission C of patient data, such as a smart phone, or a connected bracelet B or any other connected object which could collect data on the patient or collect data entered by the nursing staff, and then transmit them.
    The additional patient medical data can also be entered manually by a user, for example the nursing staff PS, and transmitted via the patient data transmission device C, such as a smart phone or a digital tablet C. These additional patient medical data include, in addition to the patient's identification (ID), other data, such as location, sex, age, weight, oxygen saturation (SpO2), heart rate, ventilation data, pathology, treatment , his blood pressure ...
    The data processing computer system E can be a physical server, a cloud server, a computer, a database or even more simply a smartphone or a digital tablet.
    As already said, the computer system E can link certain data, that is to say to pair them, and perform calculations. The data pairing means make it possible to pair patient data, such as the patient identifier (ID), all or part of the other data or information collected by the data transmission device C, B, in particular a smart phone C or a connected bracelet B, and the data collected by the wall outlet A, in particular the gas flow rate.
    It should be noted that common data can be present in the data from the gas distribution outlet A and from the patient data transmission device C, B and can therefore serve as a key for associating the rest of the data and linking them , that is to say to pair them. This common data can for example be a room number, a bed number in a room, a location in the hospital, a patient identifier (ID), a number of the wall outlet used, a correspondence table between wall outlet and bed number ... preferably the patient ID is the common data.
    The gas consumption monitoring system according to the present invention therefore makes it possible to associate for a patient and his personal data, in particular his patient ID, a consumption of medical gas over a given period of time. The invention therefore provides a system and a method for monitoring the gas consumption of one or more patients treated in a hospital building, said patients being treated by inhalation of medical gas supplied by the network of gas pipes of the hospital building, in particular oxygen, medical air or nitrous oxide, or a mixture of several of these gases.
