Problems solved by technology

Due to the permission of the national standards, the inner diameter of the infusion tube can have a size deviation of about 10% on the specified uniform inner diameter standard. In fact, different brands of infusion tubes produced by various manufacturers at home and abroad, because The difference in the manufacturing process, the different materials used and many other reasons have caused the inner diameters of the infusion tubes produced by different manufacturers or different batches of the same manufacturer to be different. Because the inner diameters of the infusion tubes are different, it directly leads to unit The amount of liquid medicine that passes through the infusion pump within a certain period of time is different from the amount objectively controlled by the infusion pump, that is, there is a deviation from the amount of liquid medicine that th

Embodiment Construction

[0012] Such as figure 1 Shown: an existing infusion pump with a sliding plate structure, its movement mode is that the sliding plate moves up and down to control the flow of liquid medicine, and the body 1 of the infusion pump is equipped with a flow control device 2 for liquid medicine, The control device 2 includes a gear position control switch 21 and a gear position control device 22. According to the requirements for ease of use, a push-button control switch 21 with 6 gear positions is provided, and is arranged on the control panel of the infusion pump main body 1. 11, and is connected with the gear position control device 22, which controls the speed of the speed regulating motor 23. The applicant provided the electrical schematic diagram of the gear position trigger switch 22, and is also provided with a display switching device 24, such as figure 2 shown. According to the requirements of the preset liquid medicine flow value per unit time, resistors with different r...

Abstract

The infusion pump includes pump body and medicine liquid flow rate controller. The medicine liquid flow rate controller includes stepped switch set on the control panel of the pump body, setting controller connected to the stepped switch and speed regulating motor unit connected with the setting controller. Branching switches are set for raising control precision of the infusion pump.

Description

Technical field: [0001] The invention relates to an instrument for medical infusion, in particular to an infusion pump with adjustable flow accuracy. Background technique: [0002] Due to the objective needs of the patient's specific condition, it is required that in the course of treatment, the amount of intravenous infusion and the speed of infusion per unit time have certain requirements, otherwise it may affect the therapeutic effect and even endanger the patient's life, so it is used for measurement. And instruments for controlling the quantity and speed of infusion per unit time have emerged at the historic moment. At present, medical instruments called "infusion pumps" are commonly used in hospitals, which are used to measure and control the quantity and speed of infusion per unit time. The principle of the existing infusion pump is to squeeze the infusion tube intermittently through the inserting plate, so that the medicinal liquid in the infusion tube passes through...
