Description
Technical field
The present invention relates to field of medical technology, especially a kind of medical equipment management control system and control method thereof.
Background technology
At present, China's medical resource is not enough and skewness weighing apparatus, causes big-and-middle-sized hospital overstaffed.The man-weapon system inspection objectively existed and privately charge observation, have impact on operational paradigm and the economic benefit of hospital greatly.The chance that Medical Devices check to patient and treat is utilized in hospital, when concrete section office or relevant operating personnel claim for charge at random, the phenomenon of meeting making patients burden is ubiquitous in present society, and this has also increased the weight of the contradiction between doctors and patients on the one hand, has also ruined the general mood in hospital.Although hospital has dropped into huge man power and material in management, still can not fundamentally address this problem.
For this, CN201420686300.5 discloses a kind of charge evasion control device for medical equipment.ID (identity number) card information is passed to computing machine by card reader of ID card by this device, ID (identity number) card information is issued payment omitted controller by computing machine, after payment omitted controller is checked ID (identity number) card information, connect Medical Devices, thus can normal medical examination be carried out, this checks and all sends control expense terminating machine to, so that carry out query statistic in the future by card reader of ID card, computing machine, payment omitted controller simultaneously.It is more direct that control take the inspection of terminating machine record patient, and more simply, the mode of robotization more, reduces the cost that hospital's payment omitted controls, and while effectively controls hospital's payment omitted.
CN201420658561.6 discloses the charge evasion control device for medical equipment of convenient inquiry.ID (identity number) card information is passed to computing machine by card reader of ID card by this device, ID (identity number) card information is issued payment omitted controller by computing machine, after payment omitted controller is checked ID (identity number) card information, Medical Devices are connected by alarm, thus can normal medical examination be carried out, this checks and all sends control expense terminating machine to, so that carry out query statistic in the future by card reader of ID card, computing machine, payment omitted controller simultaneously.It is more direct that control take the inspection of terminating machine record patient, and more simply, the mode of robotization more, reduces the cost that hospital's payment omitted controls, and while effectively controls hospital's payment omitted.Patient can grasp the fixing the price standard of every charge exactly by display screen, can check, meet the demand of patient well, also mitigate the burden of hospital financial personnel to multinomial charge.
Two above-mentioned patents all use payment omitted controller to check ID (identity number) card information, complicated operation, but payment omitted controller cost is also relatively very high.On the other hand, card reader of ID card is used to carry out authentication, application surface is narrow, smart card, magnetic stripe card or the bar code that existing hospital generally uses cannot be applied to and carry out authentication, and the interface channel of payment omitted controller and computing machine there is no the mechanism of design information secure context, payment omitted controller is easily subject to Replay Attack, making originally not meet uses the person to be used of the condition of Medical Devices to become the person to be used meeting the condition using Medical Devices, and can not check exception subsequently through inquiry system inspection, its security reduces greatly.
In view of this special proposition the present invention.
