Embodiment Construction

[0062] Below, refer to Figure 1 ~ Figure 1 0. The medical connection structure according to the first embodiment of the present invention will be described.

[0063] Such as figure 1 As shown, the medical connection structure has a male component 1 and a female connector 2, both of which work together to connect tubes 5, 5' (first and second medical components) flowing with fluids such as medical fluid or blood. Each component of the male assembly 1 and the female connector 2 are formed of resin.

[0064] First, refer to figure 1 , Figure 2B , the female connector 2 with a simple structure will be described. The female connector 2 is formed in an elongated cylindrical shape, has a female luer part 2a at one end (tip end) in the axial direction, and has a coupling part 2b at the other end (base end). The inner surface of the female luer part 2a is formed in a gentle taper shape whose diameter increases toward the tip. A pair of engagement protrusions 2c functioning as e...

Abstract

A medical connection structure comprising a male assembly 1 and a female connector 2. The male assembly 1 has a male connector 10 and a screw cylinder 20. A male lure section 11 of the male connector10 and a female lure section 2a of the female connector 2 are joined by rotating the screw cylinder 20 in the tightening direction in a state in which a female screw 21a in the screw cylinder 20 and an engagement protrusion 2c on the female connector 2 are screwed together. A torque limiting mechanism 50 is arranged between the screw cylinder 20 and an operation cylinder 30 attached to the outer circumference of the screw cylinder 20. Engagement teeth 51 are formed along the entire inner circumference at one end of the operation cylinder 30. Slits 54 are formed in one end of the screw cylinder20, said slits comprising only straight sections extending in the axial direction from said end. The areas adjacent to these slits 54 are provided as elastically deforming sections 52. Engagement hooks 53 that mesh with the engagement teeth 51 are formed in these elastically deforming sections 52.

Description

technical field [0001] The present invention relates to a medical connection structure for connecting medical components such as tubes to each other. Background technique [0002] There are various types of medical connection structures. A medical connection structure of the type disclosed in Patent Document 1 described later has a male assembly and a female connector. [0003] The male assembly has a male connector and a threaded barrel rotatably attached to the male connector. The male connector has a male luer portion whose outer circumference is tapered. The threaded barrel has a threaded portion located radially outside the male luer connector portion, and internal threads are formed on the inner periphery of the threaded portion. [0004] The female connector has a female luer portion whose inner circumference is tapered, and an engaging protrusion screwed to the internal thread is formed on the outer periphery of the front end portion of the female luer portion. ...
