Description

The easy-to-use disposable syringe

A kind of easy-to-use disposable syringe belongs to the injector for medical purpose technical field, is mainly used in blood drawing and subcutaneous or intramuscular injection and with addition of medicinal liquid etc.

Injector for medical purpose is broadly divided into the reusable and non-toxic plastic matter needle tubing pintle disposable two big classes of nature of glass needle tubing pintle in the prior art.The former transports and preserves all inconveniences, and is easy to be broken, syringe needle sterilization trouble, and easy cross infection is so now be eliminated basically; The latter since its needle tubing tail end with rib and pintle of being formed by the two block length square plastic thin plates that are decussation and tail end thereof with disk, all be that seamed edge is obvious, hard, sharp, pull or easily hurt when pushing pintle or the medical personnel's that fray finger especially during use.As medical personnel with syringe when continuously being a plurality of patient injection, gently then point and cut or grind red and swollenly, heavy then can be hemorrhage.

The purpose of this utility model is to provide a kind of advantage that can all keep existing disposable syringe, can thoroughly overcome the existing shortcoming of existing disposable syringe again, make it to become the easy-to-use disposable syringe that no longer cuts hands or mill finger when using.

According to the operation principle and the key points for operation of disposable syringe, at existing questions in the prior art, basic design of the present utility model is: transformed on the basis of existing plastics matter disposable syringe.Be about to its pintle by being that the two block length square plastic thin plates that are decussation mutually constitute all originally, change its front portion into and keep intact, and its afterbody be the cylinder bodily form and its tail end with disk and needle tubing tail end with rib on all coat one deck sponge.Thereby realization purpose of design.

Easy-to-use disposable syringe described in the utility model, (during use from lower to upper) is successively by being sleeved on needle shield 1 and the quilt cover syringe needle 2 within it that can take away when syringe needle uses outward from front to back, be connected as a single entity for the nipple 3 of loading onto syringe needle 2 usefulness of stating and be loaded in the needle tubing 4 to be with the needle tubing 4 of tail end band rib 7 and be slidingly matched and the pintle 5 of its tail end band one disk 9 constitutes with needle tubing, the afterbody 8 that it is characterized in that its above-mentioned pintle 5 of this syringe is the cylinder bodily form, and it with disk 9 and above-mentioned needle tubing 4 tail ends with rib 7 its surfaces all be coated with one deck spongy layer 6.

The utility model has the advantages that and both all kept simple in structure that existing disposable syringe had, cost is low, be convenient to transportation and preservation, need not sterilize, can cross infection etc. advantage, again because its pintle tail end and needle tubing rib have all been done improvement and special handling, make its more reasonable structure, use more convenient, neither cut hands, also do not grind hands, the health that helps improving medical personnel's work efficiency and ensure medical personnel.

Accompanying drawing is drawn back a part of overall appearance structural representation for this uses one of novel most preferred embodiment assembling back and needle shield.

Further describe architectural feature of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: on the nipple 3 that the needle tubing 4 with non-toxic plastic matter 5ml and tail end band rib 7 is connected as a single entity, suit syringe needle 2, and the needle shield 1 that its outer housing one can take off when using, the front portion is housed in needle tubing 4 is pintle 5 and the tail end band disk 9 that two block length square plastic thin plate decussations are connected as a single entity and is tubular pintle afterbody 8, all paste skim and they the corresponding to spongy layer 6 of shape separately towards the one side of syringe needle at above-mentioned rib 7 and disk 9.

Change as present embodiment:

1. the specification of needle tubing can change arbitrarily:

Rib and pintle tail end can suitably change with the shape of disk;

3. the coating mode of spongy layer 6 can change.
