Abstract
Abstract A tiltable bed automatic control system for regulation of physiological characteristics such as blood pressure within predetermined limits. For example, the patient''s blood pressure is continuously measured and monitored through the use of suitable equipment. The magnitude of that pressure selectively actuates the motor of a tiltable platform or bed to appropriately reposition the bed and affect the patient''s blood pressure accordingly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
A tiltable bed automatic control system responsive to physiological characteristics of a patient comprising: a tiltable bed; a tiltable bed motor; physiological characteristic sensing means; tiltable bed motor means operable to selectively activate said motor and establish the incline of the said bed and responsive to the output of said sensing means whereby the magnitude of the physiological characteristic controls the activation of the tiltable bed motor and incline of the bed and the patient''s physiological characteristic is held within preset limits.
Claim 2
Dependent Claim
82 words
A tiltable bed automatic control system responsive to physiological characteristics of a patient comprising: a tiltable bed; a tiltable bed motor; physiological characteristic sensing means; tiltable bed motor means operable to selectively activate said motor and establish the incline of the said bed and responsive to the output of said sensing means whereby the magnitude of the physiological characteristic controls the activation of the tiltable bed motor and incline of the bed and the patient''s physiological characteristic is held within preset limits.
Claim 3
Dependent Claim
14 words
The system as claimed in claim 1 wherein said physiological characteristic is blood pressure.
Claim 4
Dependent Claim
29 words
The system as claimed in claim 2 having manual override means selectively controlling said tiltable bed motor means to deactivate said tiltable bed motor and provide manual control therefor.
Claim 5
Dependent Claim
51 words
The system as claimed in claim 3, said blood pressure monitoring means comprising a catheter, and said tiltable table motor means further comprising checking means to review bed incline for allowable return of said bed to a horizontal position, and hypotensive means regulating bed incline when predetermined blood pressure conditions occur.
Claim 6
Dependent Claim
16 words
The system as claimed in claim 1 wherein said physiological characteristic is cerebral spinal fluid pressure.
Claim 7
Dependent Claim
14 words
The system as claimed in claim 1 wherein said physiological characteristic is cardiac rate.
Claim 8
Dependent Claim
29 words
The system as claimed in claim 1 wherein said blood pressure sensing means includes discriminating means controlling the operation of said motor with respect to preset blood pressure limits.
Claim 9
Dependent Claim
29 words
The system as claimed in claim 1 having manual override means selectively controlling said tiltable bed motor means to deactivate said tiltable bed motor and provide manual control therefor.
Claim 10
Dependent Claim
69 words
The system as claimed in claim 1, said blood pressure sensing means including means monitoring said blood pressure, means establishing selected blood pressure limits, and means comparing the monitored blood pressure and the selective blood pressure limits, signaling a predetermined dissimilarity therebetween, and storing the dissimilar signal, said tiltable bed motor means including motor control means responsive to the dissimilar signal stored in said comparing, signaling, and storing means.
Claim 11
Dependent Claim
33 words
The system as claimed in claim 9 further comprising mean blood pressure deriving means, and means comparing sensed blood pressure and derived mean blood pressure for provision to said tiltable bed motor means.
Claim 12
Dependent Claim
33 words
The system as claimed in claim 3 further comprising mean blood pressure deriving means, and means comparing sensed blood pressure and derived mean blood pressure for provision to said tiltable bed motor means.
