Abstract

Mobile functional hospital unit (1) for the temporary distribution of medical fluids, comprising at least one rear outlet (5, 25; 30) for tapping off medical fluid designed and able to be connected to a medical fluid distribution network arranged within a hospital building and associated with the rear wall (6) of the cabinet (2), at least one side outlet (21, 22, 23, 24; 17) for tapping off medical fluid associated with at least one side wall (27, 28) of the cabinet (2), and at least one connecting line (9) fluidically connecting at least one gas cylinder (3, 4; 7, 8) to at least one of the rear (5, 25) and side (21, 22, 23, 24) gas tapping outlets in order to supply at least one of the rear (5, 25) and side (21, 22, 23, 24) outlets with gas delivered by at least one gas cylinder (3, 4; 7, 8).

Claims

1. A mobile functional hospital unit for temporarily distributing medical fluids, the unit being fitted with wheels so that the unit can be moved around over the floor and comprising:

a cabinet comprising a front wall, a rear wall, side walls, a top and a bottom, and the interior of which defines at least one compartment which houses one or more medical gas cylinders and at least one medical vacuum suction pump; and

monitoring and control means designed and able to provide a user with at least one item of information relating to a malfunctioning of the unit,

and further comprising;

at least one rear outlet for tapping off medical fluid designed and able to be connected to a medical fluid distribution network arranged within a hospital building and associated with the rear wall of the cabinet;

at least one side outlet for tapping off medical fluid associated with at least one of the side walls of the cabinet; and

at least one connecting line fluidically connecting at least one gas cylinder to at least one of the rear and side gas tapping outlets in order to supply at least one of the rear and side outlets with gas delivered by at least one gas cylinder.

2. The unit of claim 1, wherein the unit comprises at least two cylinders.

3. The unit of claim 2, wherein the unit comprises at least one pair of cylinders containing a first medical gas and at least one second pair of cylinders containing a second medical gas.

4. The unit of claim 3, wherein the first medical gas is oxygen.

5. The unit of claim 3, wherein the second medical gas is air.

6. The unit of claim 4, wherein the second medical gas is air.

7. The unit of claim 1, wherein the at least one rear fluid-tapping outlet has an internal fluid-passage diameter greater than the diameter of the at least one side fluid-tapping outlet.

8. The unit of claim 3, wherein the two cylinders of a pair of gas cylinders are connected to a common connecting line connecting the two cylinders of the pair of cylinders to at least one of the rear and side gas tapping outlets.

9. The unit of claim 3, wherein the two cylinders of a pair of gas cylinders are connected to a common connecting line connecting the two cylinders of the pair of cylinders to at least one rear gas tapping outlet situated on the rear wall of the cabinet and to at least one side gas tapping outlet situated on the side wall of the cabinet.

10. The unit of claim 1, wherein a solenoid valve is provided on each connecting line.

11. The unit of claim 1, wherein a solenoid valve is provided on at least one connecting line.

12. The unit of claim 1, wherein at least one rear outlet and/or at least one side outlet for tapping off medical fluid is a vacuum suction outlet and at least one rear outlet and/or at least one side outlet for tapping off medical fluid is an outlet for distributing gas.

13. The unit of claim 1, wherein on each connecting line there are, in series between the gas cylinder or cylinders and the corresponding connecting outlet or outlets, a pressure regulator, a non-return valve and a solenoid valve.

14. The unit of claim 1, wherein on at least one connecting line there are, in series between the gas cylinder or cylinders and the corresponding connecting outlet or outlets, a pressure regulator, a non-return valve and a solenoid valve.

15. The unit of claim 1, wherein at least one rear outlet and at least one side outlet are vacuum suction outlets fluidically connected, via at least one vacuum line, to the suction intake of the suction pump so that a partial vacuum can be created at the outlets.

16. The unit of claim 1, wherein the unit comprises at least one side connecting outlet and at least one rear connecting outlet for a first type of medical gas and at least one side connecting outlet and at least one rear connecting outlet for a second type of medical gas.

17. The unit of claim 1, wherein the side connecting outlets are duplicated on the two opposite side walls of the cabinet.

18. The unit of claim 1, wherein the front wall of the cabinet comprises a control panel.

19. The unit of claim 1, wherein the control panel comprises a keypad and/or a display collaborating with the monitoring and control means.

20. The unit of claim 1, wherein at least one of the side walls has a door providing access to the internal compartment containing the cylinder or cylinders or to the internal compartment containing the pump.

21. The unit of claim 20, wherein at least one door is preferably provided on each of the side walls.

22. The unit of claim 1, wherein the interior of the cabinet comprises at least one main compartment housing one or more medical gas cylinders and at least one additional compartment in which at least the suction pump is positioned, the compartments each being fitted with one or more access doors.

23. The unit of claim 22, wherein the additional compartment is closed by a door that has ventilation slots.

24. The unit of claim 1, wherein at least one rear outlet for tapping off medical gas fluid is positioned at the upper end of the rear wall and near the top and/or at least one side outlet for tapping off medical fluid is positioned at the upper end of at least one side wall and near the top.

25. The unit of claim 1, wherein at least an upper part of the front face is inclined with respect to a vertical plane, the inclined upper part of the front wall bearing the control panel.

26. The unit of claim 1, wherein the monitoring and control means are designed and able to transmit alarm signals in order to alert the user to any malfunctioning of the unit, the malfunctioning being chosen among a reduction in the quantity or pressure of gas in one of the cylinders below a fixed threshold value;

an increase in the temperature of the pump valve above a given maximum temperature value;

detection that at least one door is open;

defective operation of at least one valve or sensor positioned on the vacuum line or on the connecting line;

a reduction in the vacuum pressure below a fixed threshold value;

a battery charge below a fixed threshold value;

or the fact that the unit is overdue for service.

27. The unit of claim 1, wherein the monitoring and control means are designed and able to transmit audible and/or visible alarm signals to alert the user to any malfunctioning and/or to display information about the malfunction on the display screen.

28. The unit of claim 1, wherein if a malfunction is detected, the monitoring and control means are designed and able to act on the pump in such a way as to stop it running, to act on a solenoid valve positioned on the outlet side is of the cylinders in order to close this valve, or to allow the gas to pass into the connecting line.
