Abstract

A control for ensuring periodical cleaning of articles of hospital and care furniture (1). The control is initiated either by manual activation when the piece of furniture has been cleaned, or when the piece of furniture (1) is driven out of the automatic washer system (2). A timer process is started and after expiration of a preset time, it is indicated on an indication panel that the piece of furniture again needs cleaning. In a parallel process, the number of activations of the control unit (12) is registered, and an indication of the requirement for cleaning is triggered when the number of activations exceeds a preset number.

Claims

1. An apparatus (13) for use in connection with cleaning of hospital and care furniture, where the piece of hospital or care furniture comprises:

at least one actuator (6,7,8,9) for adjusting the article of furniture (1),

at least one control unit (12),

at least one control (15) comprising a microprocessor said apparatus comprising;

a signaling device which can give a signal when the piece of furniture (1) has been cleaned,

a receiver for receiving the signal from the signaling device,

a timer and/or counter unit, which based on the signal starts a process to determine when the piece of furniture again needs cleaning, and

an indicator (23) which indicates when the piece of furniture (1) again needs cleaning.

2. The apparatus according to claim 1, wherein the indication of when the piece of furniture (1) needs cleaning appears after expiration of a timer function with a preset period of time.

3. The apparatus according to claim 1, wherein the indication of when the piece of furniture (1) again needs cleaning appears when the number of activations of the control unit (12) exceeds a predetermined number.

4. The apparatus according to claim 1, wherein the signaling device, which signals that the article of furniture (1) has been cleaned, is a switch or a sensor.

5. The apparatus according to claim 4, wherein the switch or sensor is activated manually by operation or automatically when the piece of furniture (1) passes an activator or signaling device, which is typically located in the washer system (2).

6. The apparatus according to claim 1, wherein the signaling device, giving off a signal that the piece of furniture (1) has been cleaned, is a temperature sensor (18) in the equipment which gives a signal when the temperature of the equipment exceeds a threshold value.

7. The apparatus according to claim 1, wherein the indication that the piece of furniture (1) needs to be cleaned manually can be controlled means of a switch on the piece of furniture (1), on a housing or on a control unit (12).

8. The apparatus according to claim 1, wherein the indication that the piece of furniture (1) needs to be cleaned has been visualized by means of indicators (23) constructed as a LED panel.

9. The apparatus according to claim 1, wherein the indication that the piece of furniture (1) needs to be cleaned at the same times shows which situation has caused the triggering of the indication and the extent of the desired cleaning by differentiating the color or blink rate of the indicator.

10. The apparatus according to claim 1, wherein the equipment (13) either is an independent unit or integral with a monitoring unit and a control (15) managing the adjustment of the piece of furniture.

11. The apparatus according to claim 1, including means for maintaining status and set-up when the mains supply is cut off in that the equipment is furnished with at least one of the following arrangements:

a. battery backup,

b. memory circuit which retains data in a no-current state,

c. minimizing of power consumption, and

d. real-time clock input for reconstructing lost data.

12. The apparatus according to claim 1, including a counter unit counting the number of times the piece of furniture (1) has been cleaned to indicate when the piece of furniture again needs servicing.

13. The apparatus according to claim 12, wherein the counter unit counting the number of cleanings of the piece of furniture (1) is equipped with a device for external control of the counter unit.

14. The apparatus according to claim 13, wherein the device for external control of the counter unit is a magnet-based switch, which is activated by placing a magnet in its presence.

15. The apparatus according to claim 13, wherein the device for resetting the counter unit is activated through communication with the microprocessor.

16. The apparatus according to claim 14, wherein the magnet-based switch is a Hall-sensor (19).

17. The apparatus according to claim 12, wherein the indication that the piece of furniture (1) needs to be serviced has been visualized by means of indicators constructed as a LED panel.

18. The apparatus according to claim 1, wherein the equipment (13) receives information concerning the pH value of the cleaning agent during washing.

19. The apparatus according to claim 18, wherein the equipment (13) is connected to or furnished with a measuring apparatus (20) for measuring the pH value of the cleaning agent during washing.

20. The apparatus according to claim 18, which calculates the factor which, together with the number of cleanings of the piece of furniture since the last servicing of the piece of furniture (1), forms part of the determination of when an indication of required servicing of the piece of furniture (1) appears.

21. The apparatus according to claim 1, including means for exchanging data with other units in the piece of furniture (1), where other units could be one of the following:

a. a control (15),

b. a gate way, or

c. a hand control (12)

and where the data to be communicated could be;

d. the number of activations of control units,

e. status for timer or counting circuit,

f. reset or initiating of times or counters,

g. set-up timer or counter thresholds,

h. the number of cleanings since the last servicing,

i. configuration of displaying on indication panel,

j. configuration of functions on keys,

k. configuration of routine of calculation of pH measuring,

l. external control of timers, counters or indicators.

22. A method for use connection in with cleaning of hospital and care furniture, including an initiation or reset state, an operating condition with indication of the status and an alarm condition,

where the initiation state, which is carried out manually or automatically with a sensor, preferably a thermo sensor, resets a timer, which goes through a period of time before the next cleaning and resetting of a counter, which counts the number of operations of a control panel, such as a hand control and at the same time updates the status on the indication panel, and

where the operating condition maintains and increments a timer in the process of a preset period of time and indicates the status of the process on the indication panel and at the same time maintains a counter, which counts the number of operations of a hand control, and where the alarm condition occurs when the preset time of the timer expires or the counter, which counts the number of operations of a hand control, exceeds a determined number, where the alarm condition is indicated on an indication panel.

23. A method for use in connection with servicing of hospital and care furniture based on the cleaning of these, including an initiation or reset state, an operating condition with indication of the status and an alarm condition,

where the initiation state is carried out manually by activating a sensor, preferably a Hall-sensor with a magnet, and brings about a resetting of a counter, which counts the number of cleanings and at the same time updates the status on an indication panel, and

where the operating condition maintains a counter, which counts the number of cleanings of the piece of furniture and as input also has a sensor, preferably a pH sensor, which measures the aggressiveness of the cleaning agent and manipulates the counter with a factor corresponding to the extra need for service, and

where the alarm condition occurs when the counter, which counts the number of cleanings of the piece of furniture exceeds a determined number, where the alarm condition is indicated on a indication panel.
