Embodiment approach 1

[0050] figure 1 It is a perspective view of the connector 1 according to Embodiment 1 of the present invention. figure 2 It is an exploded perspective view of the connector 1. The connector 1 is a male connector having a male part (male Luer) 51 . A connector 1 is provided at the end of a flexible tube 9 . The connector 1 comprises a first part 10 having a male part 51 and a second part 20 arranged on the tube 9 . The second member 20 is inserted into the first member 10, and the first member 10 and the second member 20 are connected. The first part 10 is connected to the pipe 9 via the second part 20 . For the convenience of the following description, with the tube 9 as a reference, the side close to the tube 9 is referred to as the "proximal" side, and the side away from the tube 9 is referred to as the "distal" side. The direction of rotation around the central axis is called "circumferential direction".

Embodiment approach 2

[0087] Figure 6 It is a perspective view of the side spout assembly 200 according to Embodiment 2 of the present invention. Figure 7 is a cross-sectional view of the side sprue assembly 200, Figure 8 It is an exploded perspective view of the side sprue assembly 200 . The side sprue assembly 200 includes a side sprue (may also be called a mixed sprue) 90 , and a first connector 2 a and a second connector 2 b arranged to sandwich the side sprue 90 .

[0088] The side sprue 90 includes a base 91 , a cover 94 , and a diaphragm (partition wall member) 97 . The base portion 91 has a bottomed substantially cylindrical shape that is open upward. On the outer peripheral surface of the base 91, there are provided two claws (protrusions) 93 (on Figure 6 , Figure 8 Only one claw can be observed in 93). The diaphragm 97 is configured to block the upward facing opening of the base 91 . The cover 94 is attached to the base 91 so as to cover the diaphragm 97 . The central portion...

Embodiment approach 3

[0116] Figure 11 It is an exploded perspective view of the side sprue assembly 300 according to Embodiment 3 of the present invention. Figure 12 It is an exploded cross-sectional perspective view of the side sprue assembly 300 . Like the side sprue assembly 200 of Embodiment 2, the side sprue assembly 300 includes a side sprue 90 , and a first connector 3 a and a second connector 3 b arranged to sandwich the side sprue 90 . The first and second connectors 3a and 3b are connectors of the present invention. The appearance of the side sprue assembly 300 is the same as that of the side sprue assembly 200 of Embodiment 2 (see Figure 6 ) are the same, so their drawings are omitted.

[0117] The side sprue assembly 300 is different from the side sprue assembly 200 in the following points. First, in the side sprue assembly 300, both the first and second connectors 3a, 3b are configured so that the first members 10a, 10b cannot rotate relative to the second members 20a, 20b. Se...

Abstract

The invention relates to a connector. A first member (10) and a second member (20) are coupled by a coupling part (100). In the first member, a main part (51) capable of connecting to a counterpart connector is provided on the opposite side from the coupling part. A flow channel (102) communicates the main part and the second member. One of the first member and the second member is provided with an outer cylinder part (30), and the other thereof is provided with an inner cylinder member (40). In the coupling part, the inner cylinder part is fitted in the outer cylinder part. The outer cylinder part is provided with a first engaging part (31) and a contacting part (35). The inner cylinder part is provided with a second engaging part (41) for engaging with the first engaging part, and a distal end (45) as the front end of the inner cylinder part in the direction of fitting thereof into the outer cylinder part. In engagement of the first engaging part and the second engaging part, the distal end of the inner cylinder part is brought into contact with the contacting part of the outer cylinder part along the center axis (101).

Description

technical field [0001] The present invention relates to a connector that can be favorably used for medical purposes. Background technique [0002] In the medical field, a flexible tube is used to form a flow path (sometimes called a circuit) through which various liquids such as medical solution and blood flow. A connector is used to connect different pipes. A connector is generally composed of a male connector and a female connector that can be repeatedly connected and separated. [0003] For example, a male connector and a female connector are respectively connected to the ends of the pipe (for example, refer to Patent Document 1). The connector (in the present invention, "connector" includes both the male connector and the female connector) is generally made of a hard resin material that is not substantially deformed by external force. As a connection method for connecting a hard connector and a flexible tube, solvent bonding or thermal fusion is often used. However, ...
