Novel syringe barrel structure

Abstract

The utility model relates to the technical field of medical instruments, and particularly discloses a novel syringe barrel structure, which comprises a barrel part and a Luer cone joint, a connecting part between the Luer cone structure and the barrel part is designed to be arc-shaped, and a plurality of fixing ribs are additionally arranged on the periphery of the arc structure, so that the barrel part and the Luer cone joint are fixed. Stress points between the Luer conical joint and the syringe barrel can be effectively dispersed, so that the phenomena of bending and breakage of the Luer conical joint are effectively avoided, and the product quality is ensured.

Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a novel syringe barrel structure. Background Art

[0002] In the prior art, the connection portion between the syringe barrel 2 and its Luer cone connector 1 is a step structure 3, such as Figure 1-2 As shown, the stress points between the Luer cone connector 1 and the syringe barrel 2 are concentrated at the step structure, and the Luer cone connector 1 often bends and breaks, causing the syringe product to be unusable, resulting in frequent customer complaints about product quality issues, which greatly affects the market image. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a novel syringe barrel structure, which can completely avoid the bending and breaking of the Luer cone connector.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A novel syringe barrel structure comprises a barrel portion and a Luer cone connector, wherein the barrel portion and the Luer cone connector are integrally injection molded, and is characterized in that the connection portion between the barrel portion and the Luer cone connector is an arc structure, specifically, the connection portion between the barrel portion and the Luer cone connector is designed to be an arc transition, and a plurality of fixing ribs are integrally molded at equal intervals on the periphery of the arc structure, and one end of each fixing rib is connected to the top of the barrel portion and the other end is connected to the outer peripheral wall of the Luer cone connector.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The utility model designs the connection portion between the Luer cone structure and the barrel part into an arc shape, and adds a plurality of fixing ribs on the outer circumference of the arc structure, so that the stress points between the Luer cone connector and the syringe barrel can be effectively dispersed, thereby effectively avoiding the bending and breaking of the Luer cone connector and ensuring product quality.

[0013] Now, the utility model is further described in conjunction with the accompanying drawings. The parts not described in detail below are all carried out according to the prior art in the field.

[0014] like Figure 3-5 As shown, the new syringe barrel structure of the utility model comprises a barrel portion 2 and a Luer cone connector 1. The barrel portion 2 and the Luer cone connector 1 are integrally injection molded. On the basis of the existing structure, the connection portion between the barrel portion 2 and the Luer cone connector 1 is changed from the original step structure to an arc structure 4, and a plurality of fixing ribs 5 are integrally molded at equal intervals on the outer circumference of the arc structure 4. The fixing ribs 5 and the like disperse the stress points between the Luer cone connector 1 and the barrel portion 2 to the barrel portion 2, the Luer cone connector 1 and the like, thereby increasing the bending and fracture resistance of the connection portion between the Luer cone connector 1 and the barrel portion 2, thereby completely solving the bending and fracture phenomena of the Luer cone connector, and effectively ensuring product quality.

Claims

1. A new syringe barrel structure, comprising a barrel portion and a Luer cone connector, wherein the barrel portion and the Luer cone connector are integrally injection molded, characterized in that: The connection portion between the cylinder part and the Luer cone joint is an arc structure, and a plurality of fixing ribs are integrally formed at equal intervals on the outer circumference of the arc structure.

2. The novel syringe barrel structure according to claim 1 is characterized in that: One end of each fixing rib is connected to the top of the barrel part, and the other end is connected to the outer peripheral wall of the Luer cone connector.
