Embodiment Construction

[0044] Below, enumerate embodiment and refer to attached Figure 1 to Figure 18 The syringe pump of the present invention will be described. First, the syringe 12a applied to the syringe pump 10 of this embodiment will be described.

[0045] Such as figure 1 As shown, the syringe 12 a is a general-purpose product conventionally used, and is composed of a syringe outer cylinder (outer cylinder) 18 and a pusher 16 . The syringe outer cylinder 18 has: a transparent syringe body 14 filled with a drug solution; an outer cylinder flange 20 provided on the base end side; and a discharge port 24 provided on the front end side to which a tube 22 is connected. The outer cylinder flange 20 has a substantially elliptical shape, its width in the minor diameter direction is slightly wider than the diameter of the main body 14 , and the width in the major diameter direction is set to a width that allows a person to hook his fingers. The outer cylinder flange 20 is suitably thin, for examp...

Abstract

The syringe pump (10) comprises a syringe-loading part (34) that holds the external cylinder (18) of a syringe (12a), a clamp (50) that is drawn down by an elastic body and contacts and secures the upper surface of the external cylinder (18) of the loaded syringe, a slider (60) that holds the plunger flange (28) of the plunger (16) in the loaded syringe (12a) by levers (66) and pushes the plunger (16), and a liquid crystal monitor (102), the display of which is controlled by a computer (110). Regarding the operation of loading the external cylinder (18) of the syringe into the syringe-loading part (34), the operation of setting the plunger flange (28) in the slider (60) and the operation of securing the external cylinder (18) of the syringe with the clamp (50), the liquid crystal monitor (102) alternately displays the respective states before and after the operations repeatedly at a prescribed interval.

Description

technical field [0001] The present invention relates to a syringe pump for loading and fixing various syringes and pushing a pusher flange of a pusher on the placed syringe with a slider to deliver liquid. Background technique [0002] Syringe pumps are widely used in intensive care units (ICUs) and the like to deliver medical solutions, nutritional supplements, and the like to patients accurately and over a long period of time. The syringe pump mounts and fixes various syringes, and pushes out the pusher flange of the pusher on the placed syringe while accurately controlling the speed through the slider, thereby enabling high-precision liquid delivery. [0003] The syringe pump is capable of loading syringes of various sizes, and has a structure that can easily set the liquid delivery volume, so it has high versatility. Such a syringe pump is disclosed in, for example, JP-A-2004-73373 (US7,153,290B2) and JP-A-2007-306990. [0004] In the syringe pump, in order to load syr...
