Background
Current timing situation: 1. when a clinical nurse is busy, the clinical nurse occasionally forgets the skin test time; or the skin test time is not accurate, and sometimes the specified time is not reached or exceeded. This often fails to yield accurate skin test results. 2. When a nurse uses the personal mobile phone for counting down, the hand hygiene risk exists; the nurse is reluctant to take out the personal mobile phone to time; working hours also do not allow for frequent use of a personal cell phone. 3. Nurses sometimes need multiple countdown reminders: if the pressure sore high-risk patient turns over and reminds, the primary nursing patient is reminded to patrol the ward every hour, and the like. 4. The countdown reminding device on the market at present has a single function, only supports a reminding mode, or is not simple and convenient enough in a time setting mode, and is not portable enough, so that the countdown reminding device for clinical care is not efficient enough.
The current situation of lamplight: the light is mainly used in the scene of a nurse night shift. 1. The nurse often opens and inhales a headlight when the night shift changes shifts, inhales a headlight light too dazzling, influences the patient easily and has a rest, influences the patient and experiences of seeking medical advice. 2. When a nurse carries out small treatment or nursing on a patient at night, such as blood sugar detection, blood pressure measurement and body temperature measurement in the morning, the ceiling lamp or the bedside lamp is not required to be frequently turned on, and the ceiling lamp or the bedside lamp is frequently turned on to influence the rest of the patient or sick and friends in the same room. 3. When a nurse carries out small treatment or nursing on a patient at night, sometimes the lighting is insufficient, but the nurse can complete the operation only by directional light in an operation range, and at the moment, a ceiling lamp does not need to be turned on. 4. When pupil observation is carried out on a critically ill patient, the pupil is often required to be used in time to observe the medical small flashlight, if observation is not carried out in time, judgment on the illness state of the patient is often influenced, and the optimal rescue time is missed. 5. The clinical nursing work has the condition that people can not carry a medical small flashlight or needs much time to find the medical small flashlight.
The current situation of communication: 1. some medical staff directly make a loud sound and directly call in a ward, and the sick house is not quiet, so that the hospitalization experience of a patient is influenced. 2. When the patient increases, the sound in the ward environment is noisy, and the direct loud direct calling of medical personnel often cannot hear the communication content, so that the medical communication is invalid. 3. The direct use of a personal telephone during medical communication is sometimes inconvenient, and meanwhile, the condition of missed calls exists when the telephone is silent, and the personal mobile phone is not allowed to be frequently used during working hours. 4. The interphone in the market is bulky, or has single function, does not accord with the use habit of clinical medical care personnel, and cannot be widely popularized and used among the clinical medical care personnel.
