新生儿皮肤娇嫩，使后需及时更换尿布。在临床上由于难以及时得知新生儿大小使，常会出现因更换尿布不及时而发生尿布疹，影响新生儿健康。如果定时机械性地更换尿布，常存在假换尿布，且增加护士工作量。为此，我们用自制的新生儿大小便音乐发光报知器（简称强知器）进行监测 Neonatal skin is delicate, so that diapers need to be changed in time. Because it is difficult to know the size of newborns in a timely manner, diaper rashes often occur due to diapers not being changed in time, affecting newborn health. If the diaper is changed mechanically at regular intervals, there is often a false diaper change and the workload of the nurse is increased. For this purpose, we use homemade neonatal urine and music transmitters (abbreviated as “Machine”) for monitoring.
