Abstract

Mobile apparatus for attachment to a hospital bed, gurney, wheelchair, or similar transport device, has an attendant call button operable by the patient in case of an emergency, thereby activating a signal to summon an attendant. In a preferred embodiment, the signal includes both a visual indicator and an audible indicator, wherein the visual indicator is a light positioned at the distal end of a stanchion mounted to a housing, and the audible indicator is a beeper disposed within the housing. The call button is attached to the distal end of a retractable power cord and has a clip associated therewith for securing the button to the patient'"'"'s clothing, bed covering, or other location convenient for the patient. Electronic circuitry contained within the housing and powered by a rechargeable battery is employed to sequentially control the operation of the light and beeper. The housing is easily detachable from the transport apparatus to facilitate recharging of the battery.

Claims

1. A portable alerting device for use by medical patients confined to a gurney, wheelchair, or other transport apparatus, comprising:

a housing, removably securable to the transport apparatus, having a plurality of side portions and a top portion;

signalling means mounted to said housing; and

actuating means, selectively operable by the patient, for controlling the operation of said signalling means in response to input from the patient.

2. An alerting device as set forth in claim 1, wherein:

said signalling means comprises both a visual indicator and an audible indicator; and

said actuating means controls the operation of both said visual and audible indicators in response to a single input effort by the patient.

3. An alerting device as set forth in claim 1, wherein:

said signalling means comprise electrical components; and

said actuating means comprise a source of electric power, electronic circuitry operatively connected to said power source, and switch means operatively connected to said circuitry, selectively moveable by the patient between on and off positions, said switch means being operative when in said on position to establish an electrical connection between said power supply and said signalling means thereby activating said signalling means.

4. An alerting device as set forth in claim 3, wherein:

said signalling means comprise a light and a beeper.

5. An alerting device as set forth in claim 4, further comprising:

a stanchion mounted to said top portion of said housing, selectively moveable between lowered and raised positions, having a proximate end pivotally secured to said housing and a distal end, said light being mounted on said distal end whereby said light is maintained in a vertically spaced relation to said housing when said stanchion is in said raised position.

6. An alerting device as set forth in claim 3, wherein:

said switch means comprise a button switch, normally biased in its off position.

7. An alerting device as set forth in claim 3, wherein;

said power source comprises a rechargeable battery.

8. An alerting device as set forth in claim 7, further comprising:

plug means disposed in one of said side portions of said housing, electrically communicative with said battery and engageable with an electrical outlet to effect recharging of said battery.

9. An alerting device as set forth in claim 8, wherein:

said plug means includes a male plug member pivotable between extended and retracted positions, said plug member being suitably disposed to engage said electrical outlet when in said extended position and substantially flush with said side portion when in said retracted position.

10. An alerting device as set forth in claim 7, further comprising:

a warning light for indicating a low charge for said battery.

11. An alerting device as set forth in claim 3, wherein said actuating means further comprise:

an extendable electrical cord, having a first end electrically connected to said circuitry and a second end operatively connected to said switch means; and

a retaining mechanism associated with said switch means for securing said switch means at a location remote from said housing and readily accessible to the patient.

12. An alerting device as set forth in claim 3, wherein:

said signalling means further comprise a light and a beeper; and

said circuitry includes a timer and a reset switch, said reset switch being operative to de-activate said signalling means, whereby;

upon activation of said signalling means, said light is initially activated for a preselected time period, after which said beeper is automatically activated provided that said reset switch is not operated during said preselected time period.

13. A portable alerting device for use by medical patients confined to a gurney, wheelchair, or other transport apparatus, comprising:

a housing, removably securable to the transport apparatus, having a plurality of side portions and a top portion;

signalling means mounted to said housing, comprising electronically activated visual and audible indicators; and

actuating means, selectively operable by the patient, for controlling the operation of said signalling means in response to input from the patient, said actuating means comprising

a battery for providing electrical power;

electronic circuitry connected to said battery for controlling the operation of said visual and audible indicators; and

a switch operatively connected to said circuitry and selectively moveable by the patient from an off position to an on position, said switch serving to activate said visual and audible indicators when moved to said on position by establishing an electrical connection between said circuitry and said indicators; and

a reset switch, manually operable to de-activate said visual and audible indicators.

14. An alerting device as set forth in claim 13, wherein said actuating means further comprise:

a retractable electrical cord interconnected between said switch and said circuitry, having a proximate end operatively connected to said actuating means and a distal end attached to said switch; and

a fastening device associated with said switch for attaching said switch to a location remote from said housing within reach of said patient.

15. An alerting device as set forth in claim 13, wherein said actuating means further comprise:

a timer included in said circuitry for initially activating said visual indicator for a predetermined time period prior to activating said audible indicator.

16. An alerting device as set forth in claim 15, wherein:

said timer is programmable, and is pre-programmed to sequentially activate said visual and audible indicators in three discrete stages, wherein

said first stage corresponds to said visual indicator operating in a pulsating manner, said audible indicator being inactive,

said second stage corresponds to said visual indicator operating in a continuous manner, said audible indicator being inactive, and

said third stage corresponds to said visual indicator operating in a continuous manner and said audible indicator operating in a pulsating manner.

17. An alerting device as set forth in claim 13, further comprising:

a stanchion having a proximate end pivotally attached to said housing and a distal end in spaced relation thereto, said visual indicator being disposed on said distal end,

said stanchion being selectively moveable between first and second positions, wherein said visual indicator is generally adjacent said housing with said stanchion in said first position, and maintained at a distance from said housing with said stanchion in said second position.

18. An alerting device as set forth in claim 17, wherein:

said stanchion is telescopically extendable, whereby the distance between said visual indicator and said housing when said stanchion is in said second position may be increased.

19. An alerting device as set forth in claim 13, wherein:

said battery is rechargeable, and;

said housing includes recharge means disposed therein, said recharge means comprising a plug adapted to engage a suitable source of electricity, said plug being pivotable between an extended position suitable for engaging said source of electricity and a folded position.

20. An alerting device as set forth in claim 13, wherein:

said visual indicator comprises a light; and

said audible indicator comprises a beeper.
