Abstract

The utility model provides a core rod for a medical injector, comprising a core rod body and a pressing handle at the bottom of the core rod body. The core rod body is a cross rid structure. The core rod for a medical injector is characterized in that the exterior of the lower end of each rib is a-shaped conductor which is inward smoothly collected gradually to an inflexion from top to bottom, and then the inflexion starts to smoothly open gradually to a smooth curve straightly formed by the pressing handle. The exterior of the lower end of each rib is the-shaped conductor, in particular to one section of the-shaped conductor to the pressing handle is an involute, so the combining area of the pressing handle and the core rod body is increased; binding force between the pressing handle and the core rod body is strengthened; the phenomenon of rupture is avoided; in addition, the-shaped conductor not only is beautiful, but also can be matched with fingers well in use. The core rod for a medical injector is coincidence to the principle of ergonomics; the hand feeling of the core rod for a medical injector is comfort.

Description

A kind of core bar of injector for medical purpose
Technical field
This utility model relates to a kind of core bar of injector for medical purpose.
Background technology
Have the core bar of injector for medical purpose now, comprise the hands of pressing of the core bar body of rod and its bottom.The core bar body of rod is generally cross muscle structure, and each outside, muscle rib lower end is held back for the one-level ladder and received the back vertically to the curve-like of pressing hands.The core bar of this structure, the adhesion of pressing between the hands and the core bar body of rod is little, the easy fracture when core bar of pulling back during syringe uses is firmly big slightly, and also operating handle is also relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of and uses comfortable feel, also the core bar of the injector for medical purpose of adhesion between the hands and the core bar body of rod is pressed in enhancing.
The core bar of a kind of injector for medical purpose provided by the utility model, the hands of pressing that comprises the core bar body of rod and its bottom, the core bar body of rod is a cross muscle structure, it is characterized in that: each outside, muscle rib lower end is molded lines, this molded lines begins smoothly gradually to open until the described formed smooth curve of hands of pressing from this flex point to flex point for inwardly level and smooth gradually closing from top to bottom again.
Adopted above-mentioned technical solution, the outside, each muscle rib lower end that is cross muscle core bar is molded lines, especially to the segment type line by hands be involute, increased the bonded area of pressing the hands and the core bar body of rod like this, press adhesion reinforcement between the hands and the core bar body of rod, avoided the generation of phenomenon of rupture.In addition, molded lines is not only attractive in appearance, and can be good fit with finger when using, and meets the human engineering principle, uses comfortable feel.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this utility model, it is a kind of core bar of injector for medical purpose, what comprise the core bar body of rod 1 and its bottom presses hands 2, the core bar body of rod 1 is a cross muscle structure, each outside, muscle rib 11 lower ends is a molded lines 12, and the promptly inwardly level and smooth from top to bottom gradually closing of this molded lines is smoothly gradually opened until the described hands 2 formed smooth curves of pressing from these flex point 121 beginnings to flex point 121 again.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation, therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.

Claims (1)
