FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A manually activated system contains a rigid casing; a face cover sliding on the casing; an internal chamber located between the face cover and casing. The internal chamber volume is variables by the face cover position inside the casing. The face cover is sliding between an uncompressed position in which the internal chamber volume has the maximum size, and a compressed position in which the internal chamber volume has the minimum size. A position indicating element is connected with the face cover and casing and designed to indicate the face cover position relatively to the casing in the preset positions between the uncompressed position and the compressed position. The position indicating element in addition contains an element chosen from a set of teeth and a claw located on the casing; and the remained element from: a set of the teeth and claw located on the face cover, and the set of the teeth and claw are designed to gear with each other to indicate the face cover position relatively to the casing in the preset positions between the uncompressed position and the compressed position. There are disclosed versions of the therapeutic low pressure system and a method of therapeutic low pressure pump activation.

EFFECT: enabled pump reactivation with a patient and higher reliability.
