Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0031] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0032] In addition, the ...

The invention discloses a push-and-pull box assembly of a syringe pump and a syringe pump. The push-and-pull box assembly of a syringe pump is used to fix an injector. The injector comprises a piston rod and a flange plate on the empennage of the piston rod. The push-and-pull box assembly of a syringe pump comprises a housing, clamping components on two sides of the housing, and a control handle, and a transmission component. The clamping component comprises a clamping portion and a first sleeve. The first sleeve is fixedly connected with the transmission component, so that the transmission component drives the sleeve to rotate. The end face of the first sleeve is provided with a sliding groove in a concave manner. The surface of the housing is provided with a boss. The boss is held in the sliding groove. The depth of the sliding groove on the rotation direction of the first sleeve gradually reduces, so that the boss is abutted against the bottom wall of the sliding groove, and the clamping component does fore-and-aft motion along the axial direction of the first sleeve. The technical scheme can rapidly clamp the flange plate between the clamping components and the housing, providing convenience for the push-and-pull box assembly to rapidly clamp the injector.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a push-pull box assembly of a syringe pump and the syringe pump. Background technique [0002] The syringe pump is a medical device used for intravenous infusion. The push-pull box assembly is used to push the plunger of the syringe for infusion and the clamping and fixing of the flange of the piston rod. The existing push-pull box assembly is generally provided with a clip on the surface of the shell to clamp the piston rod. The clip can be rotated relatively to form an open and closed state. When the clip is in the open state, it is loaded into the flange, and then the clip is closed. to hold the tail section of the piston. However, there are the following problems: the clip can only rotate, but cannot move away from the push-pull box assembly, the flange of the piston rod cannot fit the outer surface of the housing, and the clip can only be released by the tail fin of the cla...
