Abstract
Abstract For recording medical information on a strip chart by a strip chart recorder associated with a fetal monitoring device, a communication is initially entered into a data entry system which includes a switching membrane having a plurality of switches forming a switching network underlying the membrane. A microprocessor scans the network to identify the communication and thereafter supplies the same to a liquid crystal display for view by a user of the system prior to transmission of the communication to the recorder for recordation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
81 words
For printing by a strip chart recorder and displaying by a display device medical information, a method comprising: communicating said medical information to switching membrane means; scanning said switching membrane means; generating one of a plurality of membrane signals in response to each communication and scan; identifying said one of said plurality of membrane signals; displaying by said display device said medical information in response to said identification; and printing by said recorder said medical information in response to said identification.
Claim 2
Dependent Claim
81 words
For printing by a strip chart recorder and displaying by a display device medical information, a method comprising: communicating said medical information to switching membrane means; scanning said switching membrane means; generating one of a plurality of membrane signals in response to each communication and scan; identifying said one of said plurality of membrane signals; displaying by said display device said medical information in response to said identification; and printing by said recorder said medical information in response to said identification.
Claim 3
Dependent Claim
58 words
A method of printing and displaying medical information as in claim 1; wherein said switching membrane means comprise a plurality of depressable keys overlying a corresponding plurality of switches and wherein said communicating of said medical information comprises depressing at least one of said plurality of keys so that said corresponding switch is switched to its conductive state.
Claim 4
Dependent Claim
23 words
A method of printing and displaying medical information as in claim 2; wherein each of said plurality of membrane signals comprises digital information.
Claim 5
Dependent Claim
62 words
A method of printing and displaying medical information as in claim 3; wherein said identifying comprises reading said one of said plurality of membrane signals, counting the number of non-zero bits of information read, fetching a reference value stored in a first memory device and adding the number of said non-zero bits counted to said reference value to produce an accumulator value.
Claim 6
Dependent Claim
31 words
A method of printing and displaying medical information as in claim 4; further comprising determining completion of said communication of medical information prior to printing any portion of said medical information.
Claim 7
Independent Claim
39 words
A method of printing and displaying medical information as in claiim 5; further comprising storing a display signal and a message signal supplied by said first memory device in a second memory device in response to said accumulator value.
Claim 8
Independent Claim
39 words
A method of printing and displaying medical information as in claiim 5; further comprising storing a display signal and a message signal supplied by said first memory device in a second memory device in response to said accumulator value.
Claim 9
Dependent Claim
49 words
A method of printing and displaying medical information as in claim 6; wherein said displaying of said medical information is in response to said display device receiving said display signal and further wherein said printing of said medical information is in response to said recorder receiving said message signal.
Claim 10
Dependent Claim
25 words
A method of printing and displaying medical information as in claim 7; wherein said medical information is associated with fetal heart rate and uterine activity.
Claim 11
Dependent Claim
54 words
A method of printing and displaying medical information as in claim 8; wherein said medical information is selected from the group of functions consisting of ph, temperature, intravenous rate, oxygen rate, pulse, respiration, blood pressure, oxytocin rate, effacement, dilation, station of fetus, maternal position change, rupture of membrane, medication, fetal movement and vaginal exam.
Claim 12
Dependent Claim
52 words
A method of printing and displaying medical information as in claim 9; wherein initial depression of one of said plurality of keys communicates one of said group of functions to said switching membrane means and subsequent depressions of said plurality of keys communicates numerical data and symbols associated with the communicated function.
Claim 13
Dependent Claim
59 words
A method of printing and displaying medical information as in claim 10; wherein identifying of one of said plurality of membrane signals generated in response to said initial depression further comprises fetching an address stored in said first memory device in accordance with said accumulator value and executing a routine beginning at said address representative of said communicated function.
Claim 14
Dependent Claim
59 words
A method of printing and displaying medical information as in claim 11; further comprising storing a plurality of flag signals in said second memory device in response to said initial depression of said switching membrane means whereby identifying one of said plurality of membrane signals generated by said subsequent depressions is in response to said plurality of flag signals.
Claim 15
Dependent Claim
28 words
A method of printing and displaying medical information as in claim 12; wherein said first memory device is a ROM and said second memory device is a RAM.
Claim 16
Dependent Claim
26 words
A method of printing and displaying medical information as in claim 13; wherein said display device includes a liquid crystal display for displaying said medical information.
