(6) surgical patient information check. Nurses in the operating room through the patient's wristbands to check the patient information, and by asking to confirm whether the information is correct; surgeon in the implementation of surgery before the check again the label information, and verify that if the information is wrong, the system automatically alarm.
(7) move the rounds. In the case of a medical ward, the information in the information storage medium such as an RFID tag of a patient's bed can be quickly obtained by using a terminal device such as a mobile housekeeping machine.
(8) disease surveillance. Use a variety of portable data collectors to collect patient vital signs data and transmit them to a designated destination for further analysis and processing.
(9) smart call. When the patient emerges, the sensor signal in the intelligent pager can trigger the call function and issue an alarm in time.
(10) to monitor medication. The patient will be placed in a drug with a special label of the wisdom of the drug cabinet, medicine cabinet records the patient's various drug information. To medication time, medicine cabinet will automatically remind the patient medication.
(11) prehospital first aid. Emergency equipment can be real-time patient's vehicle inspection results back to the treatment center, so that experts can simultaneously for many patients with all-weather, borderless monitoring, diagnosis and treatment.
(12) smart bottle. The sensor will be sent to the doctor signal; if the patient forget to take medicine, the sensor will not send a signal. The doctor can remind the patient to medication on time.
Management of health care personnel
(1) regulate the behavior of medical staff. Health care workers through the RFID tag attached to the badge, you can real-time understanding of their activities information.
(2) anesthesia full safety management. An anesthesiologist must wear an RFID card through which the physician can determine whether the physician is authorized and can not enter the operating room without authorization. Before anesthesia, the anesthetist again checked the label and verified it. In addition, the drugs used for anesthesia should be checked and confirmed.
(3) management of medical staff. Into the operating room of the medical staff to wear active RFID tags, fixed RFID reader to record the time, after the medical staff to leave, the reader records each person's ID number and departure time. In the course of surgery can also record the location of each medical staff.
Management of other people
In order to ensure the safety of health care workers and the smooth development of medical work, some areas need to restrict access to personnel, with the appropriate authority to enter. The commonly used access control system can identify the identity of the person through a variety of media information, and determine whether it can enter the region.
Management of objects
Blood sample management
Blood samples in the collection of good RFID tags, samples were sent to the laboratory after the next test, data entry, re-examination, etc. can be completed by the machine, the doctor's computer directly display the test results, reducing pollution and error rate. At the same time, the whole process can be tracked.
Drug management
(1) take medicine automation. Automatic dispensing device receives the doctor's prescription and scans it, then elects the medicine on the prescription and sends it to the medicine basket. The staff will scan the RFID tag on the prescription to inform the patient for medication.
(2) infusion automation. When the liquid level of the vial is below a certain level, the pressure sensor of the vial will send the signal to the nurse station to remind the nurse dressing.
(3) center oxygen monitoring. The use of a variety of monitoring devices in real time to measure the clinical departments of the oxygen pressure, concentration and flow, when the oxygen pressure, oxygen concentration is insufficient when the alarm; the Department of oxygen metering, billing; when the ward fire, Remote shutdown of oxygen supply.
(4) smart medicine cabinet. Provide information about the drug, automatically notify the drug procurement staff in a timely manner to replenish the health care workers to take the wrong drug or the wrong dose of the behavior of a warning, in order to classify storage, distribution, audit and tracking drugs to achieve the purpose of tracking the whole process The
(5) drug security. Store the drug information in a public database, and the patient or hospital can compare the contents of the drug label with the records in the public database to see if the information is consistent.
(6) blood information management. Each blood band is equipped with an RFID tag, store the relevant information. This information is associated with the background database, so that blood in terms of blood collection, transfer point blood bank or use the hospital, can be monitored and tracked.
Supplies management
The use of bar code for medical supplies for the whole process of tracking management, so that hospital managers can grasp the procurement and use of supplies in real time. For example, tracking the use of gauze, yarn, needle and other items in the course of surgery to ensure health and safety, to prevent the end of surgery after the omission of items; through RFID tags, the equipment package recovery, cleaning, classification packaging, disinfection And other aspects of the record, and the storage of equipment packages, the use of monitoring.
Equipment management
(1) intelligent management of medical equipment. Paste the RFID tag on the medical device to track the use and changes of the device in real time.
(2) hospital central air conditioning system assessment. The central air conditioning system using the operating data and end users of the indoor environment monitoring of historical data, the central air conditioning system to conduct a comprehensive assessment of the effect.
(3) digital laboratory. The clinical laboratory automation analyzer is connected through the transmission system, the pipeline operation, to achieve sample transport, classification, pre-processing, testing, the results of the report, post-processing and so the whole process of automation.
(4) centralized management of medical equipment. On the ventilator, monitor and syringe pump and other equipment for centralized management, through the location sensor and other real-time positioning equipment department, master the situation of equipment.
(5) monitoring of large equipment. Install the appropriate sensor at a specific location, real-time transmission of equipment health and its environmental parameters.
