Abstract
A two-step injector push rod belongs to the technical field of medical instruments, and is suitable for high-capacity injectors or feeders. The two-step injector push rod comprises a main push-injection part (1), and is characterized in that an auxiliary push-injection part (2) is arranged in the front of the main push-injection part (1). Compared with the prior art, the utility model overcomes the defect that the task of injection is finished by two hands at the injection stage, ensures that the task of injection can be finished by one hand, and has the advantages of reduction of production material and production cost, convenient use, labor conservation, stable safety and the like.
Description
Technical field
The two-step injector push-rod belongs to technical field of medical instruments.Be applicable to high capacity syringe or feeder.
Background technology
The conventional injector push rod, a great majority end at injector push-rod is provided with one and propels portion.When the injectable media quantity in syringe more for a long time, the distance that the portion that propels of injector push-rod and the folder on the syringe are held between the place also strengthens thereupon, particularly when using bigger syringe, in order to finish the injection task, must with two handss work simultaneously could basic assurance task finishing.So just caused in long-time injection work medical personnel's inconvenience.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency that prior art exists, a kind of handled easily is provided, a hands just can be finished the two-step injector push-rod of injection task.
The technical scheme that its technical problem that solves this utility model adopts is: this two-step injector push-rod comprises that promoting mainly the portion of penetrating is characterized in that: be provided with pair and propel portion promoting mainly the portion the place ahead of penetrating.
The pair portion of propelling is hollow hole or circular port.Main effect is to be convenient to thumb to stretch into also handled easily.
The injector push-rod cross section is I shape or " [" type.Main effect is to make things convenient for molding.Proof strength.
The two-step injector push-rod is that disposable injection moulding is finished.
Compared with prior art, the beneficial effect that two-step injector push-rod of the present utility model is had is: 1, having solved at injection stage needs both hands to finish the deficiency of injection task, makes just can finish the injection task with singlehanded.2, reduce the production material, reduce cost of manufacture.3, easy to use, laborsaving, safety is stablized.

Fig. 1～5, Fig. 7 are the most preferred embodiments of this utility model two-step injector push-rod, are described further below in conjunction with 1～7 pair of this utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1～5:
The two-step injector push-rod is propelled portion 2 and is formed by promoting mainly portion of penetrating 1 and pair, and pair is propelled portion 2 and is the hollow hole, is convenient to that thumb stretches into and handled easily, be positioned at the place ahead of promoting mainly the portion of penetrating 1, push rod 3 is finished for disposable injection moulding, and cross section is an I shape, make things convenient for injection mo(u)lding, save material.
With reference to accompanying drawing 7:
Operation principle and work process are as follows:
Injectable media is joined in the injector cartridge 4, clamp the portion that clips of injector cartridge 4 lower ends with middle finger and forefinger, and being placed on pair, propels in the portion 2 on thumb, carry out injection work, when pair is propelled portion 2 upper ends when parallel with the bottom of injector cartridge 4, thumb is put in to promote mainly again and carries out last injection work in the portion of penetrating 1, the final injection of the medium in syringe finishes.
This two-step injector push-rod can also be used for feeder.Using method is the same.
With reference to accompanying drawing 6:
The two-step injector push-rod is propelled portion 2 and is formed by promoting mainly portion of penetrating 1 and pair, and pair is propelled portion 2 and is circular apertures, is positioned at the place ahead of promoting mainly the portion of penetrating 1, and push rod 3 is finished for disposable injection moulding, and cross section is " [" type.
Pair is propelled the hole that portion 2 can also be designed to ellipse or other shapes, as long as can make things convenient for thumb to put into.
Operation principle is identical with embodiment 1 with work process.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of this utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
