Description

"METHOD FOR DRAWING IN A LIQUID PRODUCT FROM A BOTTLE BY MEANS OF A SYRINGE"
TECHNICAL FIELD The present invention relates to a method for drawing in a liquid product from a bottle using a syringe.
The present invention- finds particularly advantageous application in drawing in liquid pharmaceutical products, to • which the following description will make explicit reference, without loosing generality.
BACKGROUND ART
For drawing in a pharmaceutical product from a bottle provided with a perforable closing membrane, it is known to set the bottle in a substantially vertical upside-down position and to draw in a given amount of pharmaceutical product by means of a syringe set in a substantially vertical position, with a suction needle thereof facing upwards .
The known methodology of drawing in a liquid product of the type described above presents some drawbacks principally deriving from the fact that the vertical orientation of the bottle and- of the syringe can lead, following upon perforation of the closing- membrane, . both to. dripping,, and hence leakage of pharmaceutical product from the bottle, and to imprecise dosage of the pharmaceutical product within the syringe caused by phenomena of cavitation and/or by phenomena of suction within the needle, and hence within the syringe, of air bubbles present inside the bottle.
DISCLOSURE OF INVENTION '
It is ' an object of the present invention to provide a method for drawing in a liquid product from a bottle by means of a syringe that will be free from the drawbacks described above and that will be simple and economically advantageous to produce .
According to the present invention there is provided a method for drawing in a liquid product from a bottle by means' of a syringe according to what is claimed in the annexed claims .
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be- described with reference to the annexed drawings, which illustrates a non-limiting example of embodiment thereof and in which:
Figures 1-4 are schematic illustrations, in side elevation, of four different operating steps of a preferred embodiment of the method of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
With reference to Figures 1-4, designated as a whole by 1 is a station for drawing in a pharmaceutical liquid product from a bottle 2 by means of a syringe 3.
The bottle 2 has a given longitudinal axis 4 ' and is closed, at an open end thereof, by a perforable elastic membrane 5, whilst the syringe 3 has a given longitudinal axis 6 and comprises a containment cylinder 7, a piston 8 slidably engaged in the cylinder 7, and a suction needle 9 engaged to the cylinder 7 itself.
The needle 9 comprises an engagement element 10, which is connected to the cylinder 7, and is provided with a- plurality of air-relief channels 11, which extend parallel to the axis 6, are uniformly distributed about the axis 6, and are made on an outer surface of the element 10 itself. The needle 9 moreover comprises a suction cannula 12 fitted on the element 10 parallel to the axis 6.
According to what is illustrated in Figure 1, drawing in the pharmaceutical product from the bottle 2 is performed by setting- the bottle 2 with the membrane 5 facing downwards, orienting the axis 4 of the bottle 2 parallel to a direction 13 set according to an angle different from 0° with respect to a substantially vertical direction 14, setting the syringe 3 with the needle 9 facing upwards, orienting the axis 6 of the syringe 3 according to an angle different from 0° with respect to the direction 14, in the case in point parallel to the direction 13, and displacing the bottle 2 and the syringe 3 with respect to one another in the direction 13 at a relatively high speed to enable the cannula 12 to perforate the membrane '5. In particular, it should be pointed out that the speed of perforation of the membrane 5 is in any case higher than the average speed normally used for displacing the syringe 3 and for displacing the cylinder 7 and the piston 8 with respect to one another.
The inclination of the axes 4 and 6 with respect to the vertical direction 14 and the relatively high speed of perforation of the membrane 5 guarantee a relatively high seal between the cannula 12 and the membrane 5 itself and enable prevention of dripping and leakage of pharmaceutical product from the bottle 2.
The inclination of the axes 4 and 6 with respect to the vertical direction 14 moreover enables orientation of possible air bubbles present within the bottle 2 along a path substantially parallel to the direction 14 and. hence prevention of their suction into the needle 9 and the cylinder 7.
Once the membrane 5 is perforated, the piston 8 is displaced along the cylinder 7 so as to enable the needle 9 to draw in a first amount of pharmaceutical product from the bottle 2. On account of the high seal between the cannula 12 and the membrane 5, the pressure within the bottle 2 decreases so as to be, at the. end of the first suction step, lower than the pressure within the cylinder 7.
With reference to Figure 2, the bottle 2 and the syringe 3 are then displaced with respect to one another in the direction 13 so .as to enable the element 10 to traverse the membrane 5 and enable the channels 11 to connect the inside of the bottle 2 to the external environment .
Consequently, the pressure within the bottle 2 increases until it reaches a value substantially equal to atmospheric pressure, and the piston 8 is displaced again along the cylinder 7 to enable the needle 9 to draw in a second amount of pharmaceutical product from the bottle 2.
In connection with what is set forth above, it should be pointed out that drawing in the second amount of pharmaceutical product from the bottle 2 must be interrupted at the latest when the level of the pharmaceutical product in the bottle 2 substantially corresponds to an inlet hole (not illustrated) of the cannula 12 so as to prevent the needle 9 from sucking air into the cylinder 7.
Next (see Figure 3), the bottle 2 and the syringe 3 are displaced with respect to one another in the direction 13 for disengaging the element 10 again from the membrane 5, the cannula 12 is kept inside the bottle 2, the axis 4 of the bottle 2 is oriented parallel to the direction 14, and the axis 6 of the syringe 3 is kept parallel to the direction 13.
At this point, the piston 8 is displaced again along the cylinder 7 to enable the needle 9 to draw in a third amount of pharmaceutical product from the bottle 2. The orientation of the axes 4 and 6 enables guaranteeing of a high seal between the membrane 5 and the cannula 12 and hence prevention of dripping and leakage of pharmaceutical product from the bottle 2. In a way similar to what has been described as regards drawing-in of the second amount of pharmaceutical product, also drawing-in of the third amount of pharmaceutical product from the bottle 2 must be interrupted at the latest., when the level of the pharmaceutical product in the bottle 2 substantially corresponds to the aforesaid inlet hole (not illustrated) of the cannula 12 so as to prevent the needle 9 from sucking air into the cylinder 7.
Finally, with reference to Figure 4, the axis 4 of the bottle 2 is oriented again parallel to the direction 13 , the axis 6 of the syringe 3 is kept parallel to the direction 13 , and the bottle 2 and the syringe 3 are displaced with respect to one another in the direction 13 with a relatively low speed for disengaging the cannula 12 from the membrane 5 and from the bottle 2. The relatively low speed of extraction of the cannula 12 from the membrane 5, which is in any case lower than the speed of perforation of the membrane 5 itself, enables the bottle 2 to be set in communication with the external environment so as to bring about ah increase in the pressure within the bottle 2 up to a value substantially equal to atmospheric pressure.
During the step of extraction of the cannula 12 from the bottle 2, the piston 8 is displaced again along the cylinder 7 to draw the pharmaceutical product contained in the needle 9 into the cylinder 7, thus preventing any possible dripping of pharmaceutical product from the needle 9 itself.
