Description

A medical equipment management and control system

technical field

The utility model relates to the field of medical technology, in particular to a medical equipment management control system.

Background technique

At present, my country's medical resources are insufficient and unevenly distributed, leading to overcrowding in large and medium-sized hospitals. Objectively, humanized inspections and privately charged inspections have greatly affected the operational efficiency and economic benefits of hospitals. Hospitals use medical equipment to give patients the opportunity to check and treat. When specific departments or related operators charge arbitrary fees, it is common in today's society that the burden on patients will be increased. This aspect also aggravates the relationship between doctors and patients. The contradiction also ruined the atmosphere in the hospital. Although the hospital has invested huge manpower and material resources in management, it still cannot fundamentally solve this problem.

Aiming at this, CN201420686300.5 discloses a medical equipment leakage control device. The device transmits the ID card information to the computer through the ID card reader, and the computer sends the ID card information to the leakage fee controller. After checking the ID card information, the leakage fee controller connects to the medical equipment, so that normal medical treatment can be performed. Check, at the same time, the ID card reader, computer, and fee leakage controller will all transmit this check to the fee control terminal for future query statistics. It is more direct, simpler, and more automated to record patient examinations on the fee control terminal, which reduces the cost of hospital leakage control and effectively controls hospital leakage.

CN201420658561.6 discloses a medical equipment leakage control device that is convenient for inquiry. The device transmits the ID card information to the computer through the ID card reader, and the computer sends the ID card information to the leakage fee controller. After checking the ID card information, the leakage fee controller connects the medical equipment through the alarm, so that Normal medical examination, at the same time, the ID card reader, computer, and missing fee controller will all transmit this inspection to the fee control terminal for future query statistics. It is more direct, simpler, and more automated to record patient examinations on the fee control terminal, which reduces the cost of hospital leakage control and effectively controls hospital leakage. Patients can accurately grasp the prescribed price standards of various charges through the display screen, and can check multiple charges, which well meets the needs of patients and reduces the burden on hospital financial staff.

Both of the above two patents use the missing fee controller to check the ID card information, which is complicated to operate, but the cost of the missing fee controller is relatively high. On the other hand, using an ID card reader for identity authentication has too narrow an application area and cannot be applied to existing smart cards, magnetic stripe cards, or barcodes commonly used in hospitals for identity authentication, and the connection channel between the controller and the computer is missing. There is no information security mechanism in the design, and the leakage fee controller is vulnerable to replay attacks, so that the unqualified users who originally did not meet the conditions for using medical equipment become the unqualified users who meet the conditions for using medical equipment, and the follow-up through the query system If no exception can be detected, its security is greatly reduced.

In view of this, the utility model is proposed.
