Claims (10)

1. Насос для подачи жидкости из контейнера к пациенту через капельницу, отличающийся тем, что насос содержит чувствительное средство для определения параметра, указывающего давление в капельнице, а также контроллер, имеющий средство вычисления и запоминания для определения отклонения данного параметра от стандартной величины, причем отклонение указывает ошибку в капельнице.1. A pump for supplying fluid from a container to a patient through a dropper, characterized in that the pump contains a sensitive means for determining a parameter indicating the pressure in the dropper, as well as a controller having calculation and memory means for determining the deviation of this parameter from the standard value, wherein indicates a mistake in the dropper. 2. Насос по п. 1, отличающийся тем, что контроллер побуждает насос входить через выбранные интервалы времени в фазу испытания во время работы насоса, фаза испытания включает в себя первую последовательность испытания, при которой насос направляет первое количество жидкости в первом направлении через капельницу, и вторую последовательность испытания, при которой насос направляет второе количество жидкости через капельницу во втором направлении, противоположном первому, во время первой последовательности испытания и второй последовательности испытания чувствительное средство определяет параметр. 2. The pump according to claim 1, characterized in that the controller causes the pump to enter, at selected intervals, the test phase during pump operation, the test phase includes a first test sequence in which the pump directs the first amount of fluid in a first direction through the dropper, and a second test sequence in which the pump directs the second amount of fluid through the dropper in a second direction opposite to the first during the first test sequence and the second follower During testing, the sensitive agent determines the parameter. 3. Насос по п. 1 или 2, отличающийся тем, что чувствительное средство измеряет изменения в диаметре трубопровода в капельнице для определения параметра, указывающего давление. 3. The pump according to claim 1 or 2, characterized in that the sensitive means measures changes in the diameter of the pipe in the dropper to determine a parameter indicating pressure. 4.
