4. Currently hospitalized patients are mainly nursing by nurses, which not only requires a large number of nurses, but also may delay the time of rescue because of the inability to observe the patient's condition changes at any time. A hospital intends to develop a computer-centric patient monitoring system, try to write out the definition of the problem, and analyze the feasibility of developing the system.

The basic requirements of the hospital patient Monitoring system is to receive each patient's physiological signal at any time (pulse temperature, blood pressure ECG, etc.) to record the patient's situation regularly to form a patient log, when a patient's physiological signal beyond the prescribed safety limits of the doctor to send a warning message to the nurse on duty, in addition, The nurse can also ask the system to print out a specific patient's condition report when needed.

For:

Problem definition: A hospital intends to develop a computer-centric patient monitoring system is to better allow the doctor to monitor the patient's physiological signal (pulse, blood pressure, ECG, etc.) changes, regularly record the patient's situation to form a patient log, to prevent the failure to find a critical patient's condition deterioration and delay the occurrence of rescue opportunities When a patient's physiological signal exceeds the prescribed safety range, a warning message is sent to the nurse on duty, and the nurse may require the system to print out a specific patient's condition report if needed.

Feasibility Study:

(1) Technical feasibility: The computer hardware of the development system has been very popular, now the computer technology are very mature, relatively speaking, the technology to develop this system is also relatively simple, so technically feasible; at the same time, hospitals must have a certain amount of system management and maintenance professionals. The hospital patient Monitoring system consists of three parts: the Guardianship Center, the Nurse Monitoring section and the Internet medical website. The monitoring center is connected to the Nurse Monitoring section, the Internet, the patient's voice heard, Video information and image data are transmitted to the Nurse Monitoring section in real time through the communication network (so that nurses can keep abreast of the patient's physiology) and the Internet Medical Center (to facilitate the sharing of physiological data).

Therefore, technical analysis is feasible.

(2) Economic feasibility: with the economy more and more developed, people can pay for the treatment of disease costs are also very high, so its development has a broad market. Currently hospitalized patients mainly by nurses, so do not only need a large number of nurses, and because can not always observe the patient's condition changes, but also may delay the rescue opportunity. The current Community health care system is not perfect, most of the collection work mainly by hand, and the information is not conducive to sharing, the data collected in a computer, the community center and the residents can not establish a time to visit and interview relationship.

(3) Operational feasibility: The popularization of computers has made the use of computer-centric patient monitoring system a foreshadowing, the system operators need to undergo professional staff guidance and training.

(4) Legal feasibility: The hospital wants to use the patient monitoring system needs to purchase the genuine software, the machine setup also needs through the legitimate channel purchase.

5. There are several types of telephone numbers available in a university in Beijing: The school telephone number is made up of 4 digits, the 1th digit is not 0, the outside telephone is divided into the city telephone and the field telephone two class, the external telephone calls to dial 0 first, if the local telephone then dials 8 digits (first not 0), For field calls, dial the 3-digit area code and dial the 8-digit number (the first digit is not 0).

Define the above telephone number by using the method of the data definition of the 2.5.2 section.

A: Phone number =[on-Campus Phone number |

School phone number = Non 0 digital +3{digital}3

Non-0 digit = [1|2|3|4|5|6|7|8| 9]

Off-campus Phone number = 0+[Local phone number | field phone number]

Local phone number = Non 0 digital +7{digital}7

Field phone number = 3{Digital}3+ non 0 digital +7{digital}7
