Abstract

The utility model relates to a syringe, comprising a container tire and a push rod, etc. The utility model is characterized in that the caudal end of the container tire is provided with two flanges, and a flute convenient for fingers holding is formed between the two flanges; the caudal end of the push rod is provided with a lantern ring capable for thumb penetrating. When the syringe is used, the thumb penetrates the lantern ring, and the fore-finger and the middle-finger clamp the flute formed between the two flanges of the container tire; at this time, the push rod not only can be conveniently 'pulled' by a hand, the push rod but also can be conveniently 'drawn', and the goal of sucking the medicinal liquid can be conveniently achieved. The utility model is of simple structure and easy use.

Description

Syringe

Technical field:

A kind of wieldy injector for medical purpose belongs to medical apparatus and instruments, is used for medical personnel and gives the patient injection medicinal liquid.

Technical background:

Generally (push rod of reusable glass syringe is cylinder to the syringe that uses at present, directly uses as piston by parts such as urceolus and push rod composition; The push rod front end of plastic injector for temporary use has piston in addition); The tail end of urceolus has a flange, works to stop the finger slippage when injection, and the push rod tail end has one to push away handle.Such syringe is when injection, and it is comparatively convenient to use; But injection is preceding when drawing medicinal liquid, it is but not too convenient to use, common way is, left hand is held medicine bottle, the thumb of the right hand and forefinger bending pinch urceolus, and its excess-three finger and the palm of the hand are held the handle that pushes away of push rod, draw medicinal liquid thereby finger firmly makes urceolus and push rod do isolating relative motion, more as medicinal liquid, such action need repeat to do one to secondary again.

Summary of the invention:

The purpose of this utility model is a kind of syringe of being convenient to operate, be easy to draw medicinal liquid of design.

This utility model is made up of parts such as urceolus, push rods, and feature is, an end of urceolus has two flanges, forms a groove of being convenient to fingerhold between two flanges, and the pushing away of push rod has the collar that can penetrate thumb on the handle.

Advantage of the present utility model is easy to use.When drawing medicinal liquid, thumb puts in the collar of push rod, forefinger and middle finger are clamped between the groove that two flanges of urceolus form, at this moment, finger firmly, can be easily push rod in the urceolus outwards " drawing " go out, the flange that increases newly on the urceolus effectively stops the slip of finger on urceolus, thereby reaches the convenient purpose of drawing medicinal liquid; And when inhaling medicine, " stroke " that moves between finger is long, general equal can once the sucking of medicinal liquid.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is vertical views of accompanying drawing 1.

The specific embodiment:

Distance between two flanges 2 of urceolus 1 tail end should be about 2 centimetres, the cross sectional shape of the groove 6 that forms between the flange 2 is that collar extension is bigger, the inside is smaller, the bottom is a circular arc, with finger that adapts to different thicknesses and the clamping of pointing different parts, and finger and urceolus 1 is better coincide; The cross section 7 of the collar 5 of push rod 3 tail ends is a flat pattern, and like this, thumb feels lighter when " drawing " push rod, the size of the collar 5, to make things convenient for thumb into and out of being advisable, push rod 3 tail ends push away the end face of handle 4, can be concave surface, can better applying be arranged with finger like this, use more comfortable.This utility model is applicable to plastic injector for temporary use, also is applicable to the reusable glass syringe in sterilization back.This utility model is applicable to 10 milliliters and following syringe, uses this utility model greater than 10 milliliters syringes, can use inconvenience inadequately because of the strength of finger.

Claims (4)

1, a kind of syringe, form by urceolus (1), push rod parts such as (3), be characterised in that, the tail end of urceolus (1) has two flanges (2), form a groove (6) of being convenient to fingerhold between two flanges (2), the tail end of push rod (3) push away the collar (5) that has can penetrate thumb on the handle (4).

By the described syringe of claim 1, be characterised in that 2, the cross sectional shape of the groove (6) that forms between two flanges (2) of described urceolus (1) tail end is that collar extension is bigger, the inside is smaller, the bottom is a circular arc.

3, by the described syringe of claim 1, be characterised in that the end face that pushes away handle (4) on described push rod (3) tail end can be a concave surface.

By the described syringe of claim 1, be characterised in that 4, the cross section (7) that described push rod (3) tail end pushes away the collar (5) on the handle is flat.
