    Description: The present invention relates to a device for dispensing a liquid.
    To administer a drug solution to a patient, the device commonly used is the so-called "drip" device, comprising a suspended reservoir and a throttle enabling the flow rate between the reservoir and the outlet pipe to be regulated. effect of gravity. This device lacks precision and despite this is commonly used.
    Some of these systems are portable and have their own power source, which allows the patient to move with minimal constraints. This represents an important advantage, especially for long-term treatments outside the hospital environment. However, the smaller the system, the lower the available power of the pump, and it can therefore be blocked relatively easily, especially if the efficiency is low.
    Dispensing devices are also known comprising a piston syringe body driven linearly in the syringe by a lead screw rotated by an electric motor. Known devices of this type, however, have the drawbacks of being expensive and reserved for complex applications, installed and monitored by professional personnel.
    The object of the present invention is to provide a portable mechanical device for dispensing a liquid which solves the problems of the cited state of the art.
    The invention relates to a device for dispensing a liquid, in particular a portable device for administering a medicinal solution to a patient, the device comprising a housing and / or a container of a liquid to be dispensed. The housing and / or container has an opening for dispensing a liquid, a support piece pressing against the housing and / or the container to control the distribution of liquid through the opening. The device also includes a drive unit for driving the support piece against the housing and / or the container thereby displacing the liquid to be dispensed towards the opening and a control member mechanically connected to the drive unit for check the drive of the support piece in order to adjust the distribution of the liquid.
    Thanks to this new portable device for dispensing a liquid, it is possible to adjust the duration and / or the volume and / or the speed of the liquid to be dispensed.
    In one embodiment, a liquid dispensing device comprises a control wheel mechanically connected to a drive unit arranged to drive a rotating shaft at an adjustable speed, a flexible container of a liquid to be dispensed, a support piece pressing against the flexible container, and a mechanical connection between the rotating shaft of the drive unit and the support piece to press the support piece against the flexible container depending on the rotation of the shaft and thus to move the liquid to be dispensed.
    In another embodiment, the flexible container comprises a flexible pocket, the support piece bears against one face of the flexible pocket, and the mechanical connection comprises an endless screw driven by the shaft in rotation to gradually press the support piece against the flexible pocket.
    In one embodiment and in particular in order not to damage or even pierce the flexible pocket, the support piece presses against the flexible pocket by means of a gas pocket.
    Preferably, the control wheel has a time scale corresponding to the training time of the processing unit.
    In one embodiment, the drive unit may include a piston.
    To be completely autonomous, the drive unit includes an energy storage means controlled by the control wheel.
    To manage different administration speeds, the device can include an adjustable speed variator arranged to regulate the drive speed of the rotating shaft.
    Alternatively, the device comprises a flexible container comprising a flexible tube, the support part comprises an eccentric cam, and the rotating shaft of the mechanical connection drives the eccentric cam in rotation to pump the liquid to be infused in the flexible tube.
    In another variant, the portable device comprises a pump, in particular a peristaltic pump equipped with a rotor carried by another shaft around which are distributed rollers driven by a movement of revolution rolling along a flexible pipe by compressing it locally against at least one presser normal to said pipe so as to allow the suction and the delivery of said liquid to be perfused.
    In one embodiment, the drive unit comprises a mechanical clockwork mechanism with manual winding, the mechanical clockwork mechanism being windable by the control member.
    The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, in no way limiting with reference to the schematic figures, in which:
    CH 714 684 A2
    Fig. 1 shows a sectional view of a device for administering a liquid according to the present invention;
    Fig. 2 shows a partial sectional view of a device for administering a liquid comprising a gas pocket;
    Fig. 3 shows a partial sectional view of a device comprising a speed controller and a worm;
    Fig. 4 shows a partial sectional view of a device comprising a speed controller and a peristaltic pump; and
    Fig. 5 shows a sectional view of a cam pump.
    As illustrated in FIG. 1, a device for dispensing a liquid to be infused according to the present invention has the shape of a teat. This device comprises a control wheel 9 mechanically connected to a drive unit 1 arranged to drive a shaft 2 in rotation at an adjustable speed. The device comprises a flexible pocket 6 of a liquid to be infused housed inside a flexible container 3. The drive unit 1 comprises a barrel 15 allowing energy to be stored, the barrel 15 being arranged to rotate in one direction when the device is running. The barrel 15 is driven by the control wheel 9, the control 9 comprising on its periphery at least one graduated scale 16 of power reserve which extends around the periphery of said control wheel 9. A marker is placed on the device for cooperating with the corresponding graduated scale 16 of power reserve located on the periphery of the control wheel 9 to indicate at each revolution or each fraction of a revolution of the barrel 15 the power reserve on the periphery of the control wheel 9 .
    A support piece 4 rests against one face of the flexible container 3 thus pressing on the flexible bag 6. The device comprises a gear train 13 and a gear train 17 arranged between the shaft 2 in rotation of the drive unit 1 and the barrel 15. The device further comprises a mechanical connection 5 comprising in this example an endless screw 7 driven by the shaft 2 in rotation to gradually press the support piece 4 against the flexible bag 6 and thus move the liquid to be infused. The liquid to be infused exits through the opening 20 arranged at the end of a part having the shape of a nipple.
    In an embodiment illustrated in FIG. 2, the support piece 4 bears against the flexible pocket 6 by means of a gas pocket 8. This gas pocket 8 not only makes it possible not to damage the flexible pocket 3 but also allows, by the flexibility of this gas pocket 8, to marry the body of the flexible pocket 3 so as to extract all the liquid to be perfused. As illustrated in this embodiment, the device includes a plug 18 for removing the drive unit and a cover 19 for removing the flexible container 3 and the flexible bag 6.
    In the example illustrated in fig. 3, the device for dispensing a liquid to be infused comprises the control wheel 9 mechanically connected to the drive unit 1 arranged to drive the shaft 2 in rotation. This shaft 2 is coupled to a speed variator 14 which regulates the speed of rotation of the worm screw 7.
    In the example illustrated in fig. 4, the drive unit 1 drives the shaft 2 in rotation at an adjustable speed. This shaft 2 is coupled to the speed variator 14 which regulates the rotation speed of a pump 10 of the peristaltic type.
    As illustrated in FIG. 5, the flexible container comprises a flexible tube 12, the support piece comprises an eccentric cam 11, and the rotating shaft of the mechanical connection drives the eccentric cam 11 in rotation to pump the liquid to be perfused into the flexible tube 12. The support piece bears against one face of the flexible container 3 thus pressing on the flexible bag 6 and passing the liquid through the pump 10.
    In a variant not illustrated, the portable pump is a peristaltic pump is equipped with a rotor carried by another shaft around which are distributed rollers driven by a movement of revolution rolling along a flexible pipe in the compressing locally against at least one presser normal to said flexible tube, so as to allow aspiration and delivery of said liquid to be infused.
