Internet of things is to point to by radio frequency identification (RFID), infrared sensors, global positioning system (GPS), such as the laser scanner information sensing device, according to the contract agreement, to any item with an Internet connection, so as to complete intelligent identification, location, tracking and monitoring and management, and other functions of a network.
The use of Internet has changed the traditional way of relying on manual work and process, can shorten the working time, improve work efficiency, also can avoid a lot of errors caused by human factors. Information searching, processing and tracing are also more convenient and efficient.
In theory, the Internet of things can manage all people and things. In the actual application of hospital, the management object of Internet of things can be divided into two kinds.
Human management
Management of patients
(1) quick visit. 's in hospital process, all links will involve the patient information of artificial records, entry, search, store patient information through the Internet of things technology in the media such as radio frequency bands or medical card, whether patients need to register, see a doctor or take medicine, can provide relevant information quickly, but also can effectively avoid the human error.
(2) baby burglar. The RFID wristband is attached to the wrist of the newborn and sets alarm function to prevent the baby from being stolen.
(3) patient behavior monitoring. As long as the patient carries the corresponding sensor, the patient can be remotely informed about the activity of the patient, and the doctor can provide guidance according to the obtained data.
(4) maternal and child corresponding management. The information of the infant RFID wristband and the information of the mother's information are set up to be the only one to avoid the mistake.
(5) out-patient wireless transfusion system. Will RFID wristbands and intravenous drip of drugs in patients with RFID tags on the match, when patients need help, just press the call button, the nurse will be on display terminal according to the patient's information, thereby help quickly.
(6) information verification of surgical patients. The nurse checked the patient's information through the patient's wristband in the operating room and asked to confirm whether the information was correct. The doctor checked the label information again before the operation, and verified it. If the information was wrong, the system automatically alerted the police.
(7) mobile inspection. When checking the room, we can use the terminal equipment such as mobile checking machine, and quickly obtain the information in the information storage media such as RFID tags in the patient's hospital bed.
(8) disease surveillance. A variety of portable data collector is used to collect data of patient's vital signs and transmit them to designated destinations for further analysis and processing.
(9) smart call. When the patient has an emergency, the sensor signal in the smart phone can trigger the call function and send out the alarm in time.
(10) monitor the medicine. The patient puts the medicine in a smart medicine cabinet with a label, and the medicine cabinet records the patient's various medication information. When it comes time to take the medicine, the medicine cabinet will automatically remind the patient to take the medicine.
(11) pre-hospital first aid. The equipment in the ambulance can transmit the patient's car inspection results back to the treatment center in real time, so that the experts can monitor, diagnose and treat many patients all day and without border.
(12) smart medicine bottle. Load pressure sensors on the bottle. Every time the patient takes the medicine and needs to wiggle the cap, the sensor sends a signal to the doctor. If the patient forgets to take the pill, the sensor won't send a signal. Doctors can remind patients to take medication on time.
Management of medical staff
(1) regulate the behavior of medical staff. The medical staff can get information about their activities in real time by wearing a badge with RFID tags.
(2) total safety management of anesthesia. An anesthesiologist must wear an RFID card, which can be used to determine whether a physician is authorized and not authorized to enter the operating room. Before anesthesia, the anesthesiologist once again checked the label's information and verified it. In addition, the drugs used for anesthesia should be checked and confirmed.
(3) management of surgical staff. Into the operating room staff wear active RFID tags, fixed RFID read-write device record in time, medical personnel when they leave after the surgery, read and write device records each person's ID number and leave time. The location of each paramedic can be recorded during the operation.
Management of other personnel
Personnel in the hospital complex, in order to guarantee the safety of the medical staff and the medical work smoothly, some areas need to limit access personnel with appropriate permissions can enter. A common access control system can identify people through a variety of media that have information about people and determine whether they can enter the area.
Management of objects
Blood sample management
Blood samples when collecting good RFID labels, samples were sent to the laboratory, the next test, data entry, review, etc all can be done by machine, according to test results in the doctor's computer directly, to reduce the pollution and error rate. At the same time, the whole process can be tracked.
Drug administration
(1) take medicine automation. The automatic drug delivery device receives a prescription from the doctor and scans it, then selects and sends the drug to the medicine basket. Workers scan the RFID tags on the prescription to notify the patient to take the drug.
(2) infusion automation. When the liquid level of the bottle is below a certain level, the pressure sensor of the bottle is transmitted to the nurse station to remind the nurse to change the medicine.
(3) center oxygen monitoring. The oxygen pressure, concentration and flow of each clinical department can be measured in real time by various monitoring devices. When oxygen pressure and oxygen concentration are insufficient, the alarm will be called. To measure and charge the oxygen content of the department; The oxygen supply can be turned off remotely when there is fire in the ward.
(4) smart medicine cabinet. Provides drug information, automatic notification drug procurement staff timely replenishment, the medical personnel take the wrong drug or using the wrong dose behavior warning to drug classification storage, distribution, audit and track, and to achieve the goal of the whole process of tracking.
(5) drug anti-counterfeiting. Storing drug information in a public database allows patients or hospitals to compare the contents of a drug label with records in a public database to see if the information is consistent.
(6) blood information management. Each blood band is equipped with an RFID tag to store relevant information. This information is linked to the background database, which enables the blood to be monitored and tracked, whether in the blood collection point, the mobilization of the blood bank or the use of the hospital.
Material management
Using barcode to carry out the whole process tracking management of medical consumables, so that hospital administrators can master the purchase and use of consumables in real time. For example, tracing gauze, gauze pad, stitches and other items during the operation of the operation, ensure hygiene and safety, prevent the missing items after the operation; RFID tags are used to record the recovery, cleaning, classification packaging, sterilization and distribution of the equipment, and monitor the storage and use of the equipment.
Equipment management
(1) intelligent management of medical devices. Paste RFID tags on medical devices to track the use and change of equipment in real time.
(2) evaluation of hospital central air-conditioning system. The effect of central air conditioning system is evaluated by using the operation data of central air conditioning room and the historical data of the indoor environment monitoring of end users.
(3) digital laboratory. Connect through the transmission system of clinical laboratory automation analyzer, pipeline operations, implement sample transport, classification and pretreatment, the whole process of automation testing, the results report, post-treatment.
(4) centralized management of medical equipment. Centralized management of equipment such as ventilator, monitor and injection pump, and control the condition of the equipment through real-time positioning equipment, such as position sensor.
(5) monitoring of large equipment. Install the corresponding sensor in a specific location, the real-time transmission equipment operation status and the environmental parameters.
(6) management of scientific research equipment. Static statistics of all kinds of data are carried out to dynamically track the use of materials by researchers.
Waste management
(1) medical waste management. Keep track of the whole process of medical waste disposal and avoid the leakage, loss and discarding of medical waste.
(2) automatic monitoring of hospital sewage and intelligent identification. For the intelligent recognition in sewage monitoring indicators and continuous monitoring, the summary of data to a central control room, the composition such as the residual chlorine in sewage of intelligent recognition, and set the abnormal alarm function.
