Definitions
- the invention relates to a method of storage and packaging, and a storage system, such as a gas cylinder, for storing a mixture of NO and nitrogen at high concentration, that is to say at least 1200 ppm by volume, preferably at least 1300 ppm by volume.
- a storage system such as a gas cylinder
- NO gaseous is conventionally used at different concentrations ranging from 100 to 800 ppm by volume (hereinafter "ppmv"), the rest of the gaseous mixture being nitrogen, to treat pulmonary vasoconstrictions, including pulmonary hypertension, in patients undergoing, undergoing or having undergone cardiac surgery or in hypoxic newborns.
- ppmv ppm by volume
- EP-A-786264 and EP-1516639 are examples of EP-A-786264 and EP-1516639.
- the NO / N 2 bottles containing the NO at the starting concentration of between typically 100 to 800 ppmv can take different sizes ranging from 2 to 40 liters (equivalent of water capacity).
- the doses of NO administered to patients range from 1 to 40 ppmv and the duration of administration varies from a few hours to a few days, for example up to 4 days on average, depending on the patient and his clinical condition. .
- NO must be diluted, typically with air, air enriched with 0 2 or mixtures N 2/0 2 prior to its administration to patients to decrease its concentration to less than 40 ppmv, that is to say up to the desired dosage for the patient considered.
- This dilution is generally performed in the patient circuit of a ventilator.
- WO-A-2005/110441 and US-A-6,581,599 teach an NO content of between 800 and 10,000 ppm by volume, the remainder being nitrogen.
- these documents indicate that the conditioning of NO / nitrogen mixtures in commercially available gas cylinders is only at maximum levels of 100 ppmv because higher levels of NO are undesirable because they may cause NO and spontaneous degradation of NO to N 2 for partial high NO pressures.
- the problem is therefore to be able to have NO / N 2 mixtures in a small storage container, that is to say less than 12 liters of capacity (water equivalent), without encountering or minimizing the problems. above mentioned autonomy.
- the solution of the invention relates to a method for storing, that is to say conditioning, a NO / N 2 mixture in a packaging container comprising an internal volume, characterized in that a mixture is preserved.
- gaseous NO / N 2 containing 1500 to 4500 ppm by volume (ppmv) of NO and nitrogen for the rest, at a pressure of at least 100 bar in the internal volume of said container, the internal volume being less than 12 liters (water equivalent).
- the content of the container is increased. NO in the container so as to use a smaller amount of NO / N 2 mixture, when it is diluted with the oxygen rich gas distributed by the medical fan supplying the patient circuit to which the container according to the invention is connected.
- the target dosage set for each patient being of the order of 1 to 40 ppmv as appropriate, typically of the order of 5 to 20 ppmv.
- Table 1 shows the volumes (in ml) of NO / N 2 administered in the inspiratory branch of the ventilator patient circuit for a volume per minute of 10 1 / min of the ventilator (ie air / 0 2 ). to obtain NO concentrations between 5 and 40 ppmv, depending on the concentration of NO in the bottle containing the NO / N 2 mixture (100 to 3500 ppmv).
- the administered volumes of NO for 5 ppmv dosages are 556 ml for a concentration of 100 ppmv NO and 14 ml for a concentration of 3500 ppmv, respectively.
- the volumes are 4444 ml for a concentration of 100 ppmv of NO and 114 ml for a NO concentration of 3500 ppmv.
- Table 2 illustrates the percentages (%) of dilution obtained for the NO concentrations from 100 to 3500 ppmv to obtain dosages ranging from 5 to 40 ppmv, under the same conditions of administration as those of Table 1 (ie ventilation of 10 1 / min).
- the dilution becomes negligible for significant NO concentrations, that is to say at least 1200 ppmv, and therefore no longer influences the parameters and the ventilatory instructions. .
- the lower the volume of NO the less it will modify the ventilation instructions and thwart the beneficial effects of the treatment, in particular the Fi0 2 .
- Tables 3 to 5 below clearly show the impact of the dilutions on the desired FiO 2 for initial NO concentrations in the 225, 450 and 2000 ppmv bottle.
- Fi0 2 is a very important parameter in the context of the pathologies treated with NO (refractory hypoxemia of the newborn, ARDS, etc.) since for these, FiO 2 of the order of 100% may be necessary. This implies that the dilution should be as low as possible to keep Fi0 2 as high as possible and thus the beneficial effect of inhaled NO treatment.
- the losses of Fi0 2 generated by the dilution can represent approximately 20 to 30% of the Fi0 2 desired (ie the target Fi0 2 ), which becomes detrimental to NO treatment because a low Fi0 2 counteracts the positive effects of NO.
- ppmv ppm by volume
- Tables 6 and 7 below show that the volume of NO necessary for a daily treatment (Table 6) or 4 days (Table 7), for an adult patient ventilated at 10 1 / min, is included, for a target concentration of 20 ppmv:
- Tables 6 and 7 clearly illustrate the difference in the size of conditioning necessary to perform a treatment in these conditions, whether daily or spread over an average duration of several days, typically 4 days.
- small size bottles typically 5 liters (water equivalent) or less, can be used even for multiple treatments. days, while for the lower concentrations, larger bottles, therefore more bulky, will be necessary, for example bottles of 20 liters for a content of 225 ppmv and a treatment duration of 4 days.
- Table 8 gives a correspondence of the characteristics of the bottles for a 4-day NO treatment for 2250 ppmv (according to the present invention) and 225 ppmv (according to the prior art) of NO for filling pressures of 200. bar.
