Embodiment Construction

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many other different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0044] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for pur...

Abstract

The invention discloses an injection pump which comprises a main machine frame, an automatic locking mechanism and an injector moving mechanism, a fixing groove used for installing an injector is formed in the main machine frame, and the automatic locking mechanism is installed on the main machine frame and used for limiting the injector in the fixing groove or releasing the injector from the fixing groove. The automatic locking mechanism is provided with a detachable arc-shaped structure capable of being matched with a syringe needle cylinder, and the shifter mechanism is installed on the main machine frame and used for generating acting force on the syringe to enable the syringe to eject liquid. Based on the fact that an arc-shaped structure in the automatic locking mechanism is detachable, injectors of different specifications can be limited by replacing different arc-shaped structures, and the injection pump can be used for installing injectors of various specifications at the same time.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a syringe pump. Background technique [0002] A syringe pump is a medical device that can apply force to a conventional syringe to output the liquid in the syringe out of the syringe. It is more convenient to use a syringe pump to inject a patient than a syringe. [0003] When using the syringe pump, it is necessary to frequently assemble and disassemble the syringe, not only to install the syringe into the fixing groove of the syringe pump, but also to detach the syringe from the fixing groove. In order to prevent the syringe from moving in the fixing groove, the syringe pump is generally equipped with a fastening structure, and the syringe can be fixed by controlling the fastening structure to be close to the syringe. The existing fixing groove and fastening structure have certain defects in mutual cooperation. The two can only realize the fixing of a syringe of a ...
