Abstract

This utility model relates to a structure of an insulin syringe. This utility model adapts a rabbet joint between a syringe and a needle bar which is used to locate a needle. A locating sleeve is arranged outside the rabbet joint to fix and hold. A protection sleeve is arranged outside the front-end of the syringe. When the injection is finished, the user can catch the protection sleeve with one hand, and nip the syringe and pull the syringe to the bottom with the other hand. The rabbet joint of the end of the protection sleeve is covered outside a locating component. The chimerical state is formed by the rib of the protection sleeve end and the end of the locating component and the needle can be put inside the protection sleeve. The utility model has the advantages of simple structure, easy operation, and safety.

Description

The insulin syringe structure

Technical field

This utility model relates to a kind of insulin syringe structure; especially refer to a kind of the injection at the end; by an over cap setting that is sheathed on the cylindrical shell outside; cylindrical shell and push rod are pulled back receipts; and make syringe needle receive to hold with drawing of cylindrical shell to be received in over cap inside, to form an insulin syringe structure of operating facility and tool safety.

Background technology

When human body can not excreting insulin or each tissue of health insulin is not reacted, affecting glucose enters muscle and fatty tissue, so the glucose content in the blood (and blood glucose) just can rise, when blood sugar increasing arrives a certain degree, and when surpassing kidney and absorbing the limit of sugar again, sugar just can be discharged from urine, i.e. its diabetes of generic person.

Therefore, need on some syringes, all can be provided with protector at the subcutaneous injection insulin, avoiding in operating process, and cause the thing of stabbing human body easily because of syringe needle exposes for the patient of insulin-dependent.

See also Figure 6 and Figure 7, be a kind of syringe construction 50 with safety guard commonly used, wherein, these syringe 50 cylindrical duct 51 outside wall surface are arranged with a safety guard 60, these safety guard 60 correspondences are located at cylindrical duct 51 outer walls upper end, the prominent axle 52 of periphery is provided with can be along these prominent axle 52 left sides, dextrorotation close and on, the rail groove 61 of following passing, and the closing lid of guard shield 60 tops is provided with for entry needle portion 53 and wears the cushion hole 62 that closes, after finishing the subcutaneous injection action, screw and upwards push guard shield 60, make rail groove 61 on the guard shield 60 be subjected to prominent axle 52 on the cylindrical duct 51 guiding and on move, and the closed injection part 53 of taking advantage of a situation, stab avoiding, prevent accident, to guarantee user and to handle the effect that the Biohazard Waste personnel obtain safety guarantee.

But, above-mentioned insulin syringe commonly used, its molding complexity, and operating procedure is too much.

Summary of the invention

The purpose of this utility model is to provide a kind of safety, processing ease, the simple insulin syringe of member for overcoming above-mentioned defective.

For achieving the above object, this utility model provides a kind of insulin syringe structure, its formation comprises: one has room is located in the cylindrical shell for the cylindrical shell that holds medicament, and is nested in the lid that needle guard and that barrel front end is sheathed on the syringe needle outside for the sheathed needle stand of syringe needle, is placed on the push rod end for the push rod of pushing medicament, and forms, form an insulin syringe structure by above-mentioned member, it mainly improves and is:

The nested place with needle stand of this barrel front end outer race is provided with positioning piece, be provided with an over cap in the cylindrical shell outer cover in addition, be provided with the bigger fitting portion in an aperture in the inside of over cap end, and the lid end inwardly is provided with the front end that makes over cap and just supports the embedding rib that terminates in needle stand, makes this over cap be sheathed on the cylindrical shell outside;

In injection at the end; user can one be held to the over cap outside; another hands and cylindrical shell and push rod pulled back is pulled; this power just can make the fitting portion sliding sleeve of over cap end go into the keeper outside of barrel front end; and do not hold to form by embedding rib and keeper and fasten the location; make syringe needle receive to hold and close at over cap inside, form the insulin syringe structure of a quick and tool safety simple to operate with drawing of cylindrical shell.

In other words; it mainly is to be arranged with an over cap outside cylindrical shell; this over cap terminus inner is provided with the bigger appearance in an aperture and stretches the space; and inwardly be provided with the embedding rib in the lid end; to form a fitting portion; in injection at the end; user can one be held to the over cap outside; another hands and cylindrical shell and push rod pulled back is pulled; this power just can make the fitting portion sliding sleeve of over cap end go into the keeper outside of barrel front end; and fasten the location by terminal formation of embedding rib and keeper; make syringe needle be able to pull and hold and close in this over cap with the receipts of cylindrical shell; its member is simple and operation is fast convenient, can effectively avoid stabbing, thereby form an insulin syringe structure that has a safety.

Learn that by above explanation this utility model prior art of comparing can reach following effect:

1, safety: because this utility model cylindrical shell outer cover is provided with over cap; can be after injection finishes; cylindrical shell and push rod are pulled back receipts; make the fitting portion of protective sleeve end and chimeric mutually the fixing of keeper of barrel front end; and syringe needle is able to receive to hold with drawing of cylindrical shell be received in the over cap; preventing that syringe needle from stabbing the people, thus the effect that reaches safe handling and reclaim.

2, simple to operate: because the terminal formed inlay card of the fitting portion of this utility model over cap end and keeper location; when drawing the cylindrical shell of pulling to pull back the time receiving; make the fitting portion sliding sleeve in the keeper outside; and make the embedding rib of fitting portion and positioning seat fasten the location mutually; syringe needle is held to be received in the over cap; its simple to operate and safety makes overall structure have intention and splendid usability benefit really.

3, member is simple: because the simple structure of this utility model over cap and keeper, and molding is easy, has the industrial applicability benefit really.
