Abstract

The utility model relates to a small-dosage screw-socket injector. A small concave slot is additionally arranged on a common conical connector of a common small-dosage injector, and a plurality of convex anti-slide ribs are vertically and additionally arranged on the small concave slot. A lock connector complying with the standard requirement is additionally arranged, and a plurality of anti-slide concave slots are additionally arranged on an assemble hole of the lock connector. Concave positions and convex positions are formed and matched after assembly, the connection is firm, no sliding exists, the firm lock with the matched injection needle in utilization is guaranteed, no disconnection exists, the liquid medicine wastage and the danger of stabbing other people caused by the disconnection of the injection needle are avoided, and the requirements of clinical utilization are satisfied. The utility model has the advantages of convenient operation, good safe performance, accurate medicine utilization and liquid medicine wastage prevention.

Description

Low dose of screw socket syringe

Technical field

This utility model relates to a kind of low dose of syringe, belongs to medical instruments field.

Technical background

Low dose of syringe is mainly used in injection trace or little medicine amount liquid, is usually used in injection of insulin, the injection of skin test, costly medicine.

Because it is the connected mode that adopts common cone joint that the low dose of syringe that uses at present connects entry needle, when clinical use, easily cause low dose of syringe and entry needle to come off, when clinical injection, not only caused liquid waste, and stab other people easily, most important reason is that the waste because of medicinal liquid causes the inaccurate of dosage, does not reach the requirement of clinical application.Especially at present the low dose of syringe that uses is when configuration skin test medicinal liquid, need with the fixing place that joins of entry needle and overcoat of hands, prevent that entry needle is when suction and ejaculation medicinal liquid, cause because of joint is loosening to injure medical worker or other people when entry needle drops or syringe needle together penetrates with medicinal liquid when penetrating medicinal liquid, this has brought great inconvenience to the medical worker.

Summary of the invention

The purpose of this utility model is to provide a kind of security performance good, medication is accurate, and easy to operate low dose of screw socket syringe, the locked joints of its configuration adopt standard locking-type joint design pattern, can with the supporting use of conventional entry needle, in use do not break away to guarantee its supporting entry needle.

This utility model is to increase by a little groove on the common cone joint of common low dose of syringe, the vertical anti-skidding muscle that increases several projectioies on the groove; Other increases the locked joints that a conformance with standard requires, and has increased corresponding several antiskid grooves on the pilot hole position of locked joints; The assembling back forms convex-concave position and is complementary, and is connected and fixed, and does not slide, and it is fastening to guarantee that the entry needle supporting with it in use locks, and does not come off.

The concrete scheme of this utility model is a kind of low dose of screw socket syringe, comprises syringe jacket, core bar, rubber piston, it is characterized in that: set up a little groove on the syringe cone joint, the vertical anti-skidding muscle that increases by 2-6 projectioies on the groove; Other increases the locked joints that a conformance with standard requires, and has increased corresponding 2-6 antiskid grooves on the pilot hole position of locked joints; The assembling back forms convex-concave position and is complementary.

The locked joints that the low dose of syringe of this utility model disposes on low dose of syringe adopts standard locking-type joint design pattern, make that the connection entry needle is more firm, and because of screw socket and syringe jacket are isolating accessories, can be according to clinical different needs, produce screw socket syringe or common cone joint syringe, satisfy clinical user demand.

Specific embodiment

The low dose of syringe of this utility model comprises syringe jacket 1, core bar 3, rubber piston 4, is to increase by a little groove on the common cone joint of common low dose of syringe, the vertical anti-skidding muscle 5 that increases by 4 projectioies on the groove; Other increases the locked joints 2 that a conformance with standard requires, and has increased corresponding 4 antiskid grooves 6 on the pilot hole position of locked joints; The assembling back forms convex-concave position and is complementary, and is connected and fixed, and does not slide, and it is fastening to guarantee that the entry needle supporting with it in use locks, and does not come off.Shown in Figure 1, this low dose of screw socket syringe construction installation diagram assembly of the present utility model is syringe jacket and locked joints, forms low dose of screw socket syringe jacket assembly.Shown in Figure 2, on the common cone joint of common low dose of syringe, increase by a little groove, the vertical anti-skidding muscle 5 that increases by 4 projectioies on the groove forms convex-concave positions with antiskid groove 6 assembling backs on the position, locked joints hole and is complementary, and is connected and fixed, and does not slide.Fig. 3 is 4 antiskid grooves on the pilot hole position of locked joints, forms convex-concave position with the anti-skidding muscle assembling back of cone joint upper groove projection and is complementary, and is connected and fixed, and does not slide.
