Definitions

• the present invention concerns an electromechanical device for signalling the level in the phleboclysis ' containers, comprising a mechanical structure and an electronic alarm central.
• said care means a considerable engage- ent for the nurses, specially at night, when they must control a plurality of patients at the same time that are undergoing the same treatment.
• an electromechanical device for signalling the level in the phleboclysis containers comprising a mechanical structure working by means of the emptying of the container and an e- lectronic central, consisting in a control card.
• Figure 1 shows a vertical scheme of an electromecha ⁇ nical device for signalling the level in the phleboclysis containers.
• Figure 2 shows a scheme of the working of the device.
• Figure 3 shows a block scheme of the electronic cen ⁇ tral.
• the figures show an electromechanical device for sig ⁇ nalling the level in the phleboclysis containers, com ⁇ prising a mechanical structure consisting of a small movable basket 1 for supporting the liquid container C, connected to a vertical rod 2 that works inside a cylindrical support 3 by means of axial bearings and calibrated springs, bringing the sliding sensibility to friction "zero".
• the device works through the emptying of container C. Said container, once the desired level has been reach- ed by means of the run of the internal axis, closes the electric contact by operating the alarm of the cen ⁇ tral CE.
• the cylindrical support 3 that has the function of carrying structure, comprises a calibrating system that works by means of a calibrated tap 4 onto which the outlet jack and the switch are mounted, that are not shown in the figures.
• the jack must be connected to the outlet cable from the central .
• the electronic control consists of an electronic card having the following features:
• the central CE works with a 9-Volt battery and is provided for working with 12, 110 and 220 Volt.
• the feature related to the wall tap PM allows - when the central CE starts the alarm - to automatically call the responsible nurse due to the centralized system * used in nursing homes and in hospitals.
• Said jack has also the function of switch, thus pre ⁇ venting the feeding battery from discharging when the device is not connected ot the sensor.
• the control block receives information from outside and transforms it into appropriate signals.
• an external alarm AE that may be adapted to various requested outlet stations; in the specific case, said signals consist in the closing, for about one second, of the relais contact.
• the inlet signal of the interface block ext IE may be used for the control of other interfaces with the out ⁇ side so as to control any electromechanical and/or e- lectronic system. Furthermore, the device is provided with a reset com ⁇ mand RS, with the option of eventually inserting a test switch.
• control block BC that clashes with the integrated IC 1
• the functioning of the control block BC may be describ ⁇ ed as follows:
• - PIN 13 (acoustic interface): presence of a square wave that, operating on T1, produces an intermit- tant acoustic alarm; said condition on PIN 13 also produces the intermittance of the optical alarm;
• the reset control operates bringing the PIN 6 of the integrated to 0 Volt.
• the device according to the present invention has such functional features as to make it suitable to many o- ther applications, like e.g.:
• liquid level water, fuel, milk, etc.
• movable tankers systems for controlled irrigations and so on.
