Description

A kind of disposable syringe

Technical field: this utility model relates to a kind of medical apparatus.

Technical background: the disposable syringe of prior art, when drawing medicinal liquid, can operate with single method or two people's methods, but the general single method that adopts: the left hand palm upwards more, clamp the ampoule body with thumb, forefinger, the right hand inserts the syringe needle on the syringe in the ampoule, and other refer to hold the syringe front end with left hand then.The right hand moves to a bolt rear end and holds a bolt handle, pull tube bolt gradually, and medicinal liquid then is sucked in the syringe.The operational approach step of this syringe is more loaded down with trivial details, wastes time and energy, and is unfavorable for the treatment of rescue property.Because tube outside a bolt is exposed to after getting it filled fully, to the infusion bottle dosing time, often needs repeated multiple times push-and-pull tube bolt to get it filled and dosing, easy like this making is exposed to an outer tube bolt and polluted, and then pollutes medicinal liquid.

Technology contents: the purpose of this utility model is for overcoming the above-mentioned defective of existing in prior technology, and a kind of novel disposable syringe is provided.This utility model is to improve realization on the basis of existing technology.It comprises syringe and the tube bolt that has milliliter scale and tube mouth, and its main points are to have two symmetrical arc backplates on the bolt handle of a bolt, and arc backplate end is provided with pushing face, and two wing handle inner edges up and down of syringe tail end are equipped with side shield.

During use, press on the pushing face of two arc backplates about the tube bolt respectively with right hand food, middle finger, thumb props up a wing handle of syringe simultaneously, the side shield of wing handle inner edge makes thumb avoid touching a bolt, needle point and needle body are stretched in the ampoule that left hand holds, and place under the liquid level, right hand food, middle finger are slowly pushed pushing face backward, the tube bolt is promptly slowly taken out of, thereby sucks medicinal liquid to syringe.

This utility model is reasonable in design, and is simple to operation, owing to be provided with arc backplate and side shield, makes the tube bolt after getting it filled become semi-closed state by exposing fully, is difficult for touching a bolt during operation, significantly reduced opportunities for contamination.Adopt the three finger pressure methods of pinching to get it filled and the comparison of getting it filled of traditional both hands pulling plug method, more time saving and energy saving.

Specific implementation method: according to Fig. 1, Fig. 2, shown in Figure 3, the head end of syringe 3 has a mouth 1, and syringe 3 stack shells are provided with milliliter scale 2, and tail end has two wing handles 6 up and down, and each wing handle 6 inner edge is equipped with vertical with it side shield 7.The tube bolt handle 8 of tube bolt 9 tail ends is provided with two symmetrical arc backplates 5, and its direction is parallel with the tube bolt, and the cambered surface bag of arc backplate 5 is to syringe 3, and arc backplate 5 ends have pushing face 4, and arc backplate length slightly is longer than the total length of milliliter scale 2.

Claims (1)

1. A kind of disposable syringe, comprise the syringe (3) that has a mouth (1), milliliter scale (2) and wing handle (6), and the tube bolt (9) that has arc backplate (5) on the tube bolt handle (8), it is characterized in that having two symmetrical arc backplates (5) on tube bolt handle (8) of a bolt (9), arc backplate (5) end is provided with pushing face (4), and the inner edge of two wing handles (6) up and down of syringe (3) tail end is equipped with side shield (7).
