Embodiment approach 3

[0197] The male connector 10 connected to the female connector 15 described in (Embodiment 1) and an example of the male connector P (male connector 30) described in (Embodiment 2) are each integrally molded. on the port of the medical container. However, these male connectors may also be detachably connected to the ports by means of a connecting mechanism.

[0198] Such as Figure 13 As shown, the male connector 60 as an example of the male connector P of the present invention includes a pedestal 62, a tubular portion 61 protruding downward from the center of one main surface of the pedestal 62, and is arranged on the side opposite to the tubular portion 61 of the pedestal 62. A side cap portion 68 and a pair of engaging claws 64 protrude outward from the outer peripheral surface of the pedestal 62 . The base 62, the tubular portion 61, and the engaging claw 64 may have the same structure as that of the male connector 30 described in (Embodiment 2). On the inner peripheral...

Abstract

A female connector (15) is provided with engaging walls (217) having surfaces which face engaging claws (14) when the female connector (15) is being connected to a male connector (10), and the surfaces include sloped surfaces (222). When the female connector (15) and the male connector (10) become connected together, the engaging claws (14) move up along the sloped surfaces (222) in the direction of sliding of the engaging claws (14) relative to the engaging walls (217). A male connector (30) is provided with engaging claws (34) having surfaces which face engaging walls (417) when a female connector (35) is being connected to the male connector (30), and the surfaces include sloped surfaces (34a). When the female connector (35) and the male connector (30) become connected together, the engaging walls (417) move up along the sloped surfaces (34a) in the direction of sliding of the engaging walls (417) relative to the engaging claws (34).

Description

technical field [0001] The present invention relates to a female connector, a male connector, a connection structure, a liquid feeding circuit including the female connector, and a medical container including the male connector. Background technique [0002] Enteral nutrition therapy and parenteral nutrition therapy are known as methods of administering nutrition or pharmaceuticals to patients parenterally. In enteral nutrition therapy, a gastrostomy (the tube that will form the gastrostomy) is created via a tube that passes from the patient's nasal cavity to the stomach or duodenum (commonly called a "nasal tube") or inserted into the patient's abdomen. The operation is called "Percutaneous Endoscopic Gastrostomy, percutaneous endoscopic gastrostomy") tube (commonly called "PEG tube") to give liquids such as nutrition, liquid food or medicine (commonly called "enteral nutrition "). In addition, in parenteral nutrition therapy, a liquid substance (generally referred to as ...
