Embodiment Construction

[0038] The detection liquid circuit composed of infusion pump or syringe pump and detection device, the infusion pump or syringe pump continuously injects liquid into the detection device according to the set flow value, and the liquid passes through the detection liquid circuit and is discharged from the detection device. The internal structure of the detection device is as follows: figure 1 shown. When the detection device performs flow measurement, it performs a continuous liquid feeding and discharging cycle. The specific process is as follows:

[0039] (1) The liquid enters the measuring pool through the normally open ends of the three-way valve 1 (ie the first three-way valve) and the three-way valve 2 (ie the second three-way valve). The measuring pool is composed of 8 sets of luminescent tubes and receiving tubes The measurement array is used to measure the position of the liquid level. When the liquid level rises to the first group of light-receiving pair tubes, the t...

Abstract

The invention discloses a medical syringe pump and infusion pump detection device and method. The device comprises a first three-way valve, a second three-way valve, a measuring cell, an effusion boxand a pressure sensor. An input port of a to-be-detected syringe pump or infusion pump is connected with the inlet of the first three-way valve; one output port of the first three-way valve is connected with the effusion box and the other output port is connected with the input port of the second three-way valve; one output port of the second three-way valve is connected with the effusion box andthe other output port is connected with the bottom of the measuring cell; the measuring cell is cylindrical; a measuring array is arranged along the height direction of the measuring cell; and the measuring array is used for measuring the height of the liquid level in the measuring cell so as to obtain flow data. The device is stable in measuring result and high in measuring precision, is capableof restoring certain disturbances and abnormal conditions, and is simpler, more reasonable and more convenient in operability when being compared with imported equipment.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for a medical injection pump and an infusion pump, which is used for periodic detection and quality management of the infusion pump and the injection pump. Background technique [0002] Some of the infusion pumps used in domestic medical equipment are imported from abroad, and only imported "bare pumps" are selected. The infusion consumables used are not completely matched, and abnormal flow rates or other related medical accidents are prone to occur, but the medical staff did not know before the actual use this problem. Domestic infusion pumps basically imitate foreign technology, and the manufacturing process is worse than that of imported equipment. It lacks the key part of the "computer drug database" (determines the infusion rate according to different drug parameters), and does not perform the rate according to the performance of infusion equipment and consumables du...
