Intelligent terminal for hand hygiene compliance supervision

Abstract

The invention provides an intelligent terminal for hand hygiene compliance supervision. The intelligent terminal comprises a wearable terminal used for being worn on the human body and a signal projector which is used for being installed on a specific position of an inpatient ward; the wearable terminal comprises a main controller, a low-frequency sensing module, an attitude sensing module, a man-machine interaction module, an acoustic-optic alarming module and a power module, and the low-frequency sensing module, the attitude sensing module, the man-machine interaction module, the acoustic-optic alarming module and the power module are connected with the main controller; the main controller comprehensively judges whether personnel are in contact with an infection source or not or clean the hands or not according to information acquired by the low-frequency sensing module and the attitude sensing module, and gives out prompting information through the acoustic-optic alarming module according to the judgment result; meanwhile, personnel feedback information is received through the man-machine interaction module, the judgment result is corrected, and a judgment mechanism is improvedaccording to the correction result. By means of the intelligent terminal for the hand hygiene compliance supervision, mixed sensing technologies like low-frequency sensing and recognition, attitude sensing and infrared approach sensing are comprehensively adopted, and the executing situations of hand hygiene can be effectively monitored.

Description

technical field [0001] The invention relates to the field of medical intelligent electronic equipment, in particular to an intelligent terminal for hand hygiene compliance supervision. Background technique [0002] Bacteria carried by hands of medical staff is the main source of nosocomial infection. Direct or indirect hand-to-hand transmission of bacteria causes infection and accounts for more than 30% of nosocomial infections. Strict hand washing by medical staff can reduce the carrying of pathogens and effectively cut off direct contact transmission. The U.S. Centers for Disease Control and Prevention released hand hygiene guidelines for medical institutions in October 2002, confirming the effectiveness of hand hygiene and pointing out that compared with other nosocomial infection management measures, hand hygiene is the most direct, simplest, and easiest way to reduce nosocomial infections. One of the most economical and effective measures, it plays a huge role in no...

Problems solved by technology

[0009] Before touching the patient: It is impossible to judge whether the medical staff is in contact with the patient only by the sensing distance, which leads to the wrong timing of hand hygiene and hand washing before contacting the patient, which causes a lot of work burden for the medical staff;

[0010] Before cleaning or aseptic operation: It is impossible to judge whether the medical staff is performing aseptic operation only by the sensing distance. When the medical staff enters the sensing area, it is considered aseptic operation. bring a lot of work;

[0011] After contact with the patient's body fluids: Only low-frequency 125K signals are used to solve the problem of intelligent identification of personnel, and it is impossible to determine whether they have been in contact with the patient's body fluids;

[0012] After touching the patient: the existing technology judges that when the medical staff leaves the bed area after contacting the patient, if they do not sense the low-frequency 125K signal emitted by the bed, they are considered to have left the bed area. This is inaccurate. In actual clinical scenarios, due to the The problem of the low-frequency 125K signal distance is that when medical staff get up to pick up things or do other operations, they will misjudge that the medical staff has left the bed without sensing the signal emitted by the hospital bed, which will interfere with the operations of volunteers when rescuing or nursing patients , affect the emotions of medical staff, and cause a lot of work burden to medical staff;

[0013] After contact with the patient's surrounding environment: the existing technology only uses low-frequency induction technology, which cannot solve the problem of judging the medical staff's contact with the patient's surrounding environment. It will judge that the medical staff has been in contact with the surrounding environment of the patient, and will frequently remind the medical staff to perform hand hygiene, causing a large number of misjudgments, interfering with the work of the medical staff, and causing a great workload to them

[0014] To sum up, only low-frequency induction technology is used in the prior art. Through distance discrimination, it can only solve the identification problem of medical staff, and cannot accurately determine the timing of hand hygiene for medical staff, and it will cause great harm to medical staff. It violates the original intention of designing the hand hygiene system to improve the work efficiency and hand hygiene compliance of medical staff

In addition, its contact discrimination is generally completed through the background server, which has a certain lag and is easily affected by network interference.
