Problems solved by technology

like figure 1 As shown, these liquid pushing pieces 1 are used to continuously squeeze the infusion tube from top to bottom, so as to realize automatic infusion operation. After a long time of use, the elasticity of the infusion tube will decrease, and the actual service life of the infusion tube will be shortened
More importantly, since the deformation of the infusion tube itself cannot be recovered, the accuracy of the infusion (the stability of the infusion speed and the infusion volume) will be greatly reduced, which will adversely affect the patient and even cause personal injury

Embodiment Construction

[0027] The specific implementation manners of the present invention will be described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0028] First refer to figure 1 , which shows a general cross-sectional view of an infusion device according to a preferred embodiment of the present invention, which includes: a drive shaft 1 connected to a driving device (not shown in the figure), such as a stepping motor; a first liquid stop block 4 and the second liquid stop block 7, both of which are rotatably sleeved on the transmission shaft 1, and periodically squeeze the infusion tube 9 with the rotation of the transmission shaft 1 to temporarily prevent the liquid medicine from The flow in the infusion tube; two liquid pushing blocks 5 and 6, which are also rotatably sleeved on the transmission shaft 1, and periodically squeeze the infusion tube 9 to push the liquid medicine in the infusion tube In the medium flow, the pusher blocks 5,...

Abstract

The invention provides an infusion device, which can be used for an infusion pump and comprises a transmission shaft, a liquor stopping block and at least one liquor pushing block, wherein the transmission shaft is connected with a driving device; the liquor stopping block comprises a first liquor stopping block and a second liquor stopping block and can be sleeved to the transmission shaft in a rotating way and periodically extrude an infusion tube along with the rotation of the transmission shaft so as to temporarily stop the flowing of liquor in the infusion tube; the at least one liquor pushing block is sleeved to the transmission shaft in the rotating way, periodically extrudes the infusion tube so as to push the liquor to flow in the infusion tube and is positioned between the first and second liquor stopping blocks; and the lateral end face of the liquor pushing block extruding the infusion tube is a flat end face.

Description

technical field [0001] The present invention relates to medical devices, in particular to infusion devices such as those used in infusion pumps. Background technique [0002] During the infusion process using the infusion pump, it is necessary to ensure the stability of the infusion speed and accurately control the infusion volume within a period of time. In the currently commonly used squeeze infusion control devices, a plurality of liquid pushing pieces 1 are arranged along the infusion tube mostly, and the tops of these liquid pushing pieces 1 are formed with protrusions 1a for squeezing the infusion tube. figure 1 A typical infusion control device in the prior art is shown in . Such as figure 1 As shown, these liquid pushing pieces 1 are used to continuously squeeze the infusion tube from top to bottom, so as to realize automatic infusion operation. After a long time of use, the elasticity of the infusion tube will decrease, and then the actual service life of the inf...
