Embodiment approach 1

[0046] figure 1 It is a perspective view of a male connector with a lock mechanism (hereinafter simply referred to as a "male connector") 1 according to Embodiment 1 of the present invention. figure 2 A is a top view of the male connector 1, figure 2 B is a side view of the male connector 1 . also, image 3 It is a cross-sectional perspective view of the male connector 1 .

[0047] The male connector 1 according to Embodiment 1 includes a rod-shaped male guide 10 as a male member. exist image 3 Among them, 10a is the central axis of the male inducer 10. Hereinafter, for convenience of explanation, the longitudinal direction (direction parallel to the central axis 10a) of the male-type inducer 10 is referred to as the "up-and-down direction", and the direction perpendicular to the longitudinal direction of the male-type inducer 10 is referred to as the "horizontal direction". . In addition, in the up-down direction, the side closer to the base 19 is called "lower sid...

Embodiment approach 2

[0080] Figure 9 It is a perspective view of a male connector with a locking mechanism (hereinafter simply referred to as a "male connector") 2 according to Embodiment 2 of the present invention. The male connector 2 of Embodiment 2 differs from the male connector 1 of Embodiment 1 in that: On the shield 20 , an end edge 20 a from the upper side thereof is formed parallel to the male guide member 10 . A pair of cutouts 23 extending toward the abutment 19 . The pair of cutouts 23 face each other across the male guide 10 , and the direction in which the pair of cutouts 23 face each other is substantially perpendicular to the direction in which the locking lever 30 and the male guide 10 face each other.

[0081] The usage and operation of the male connector 2 according to the second embodiment configured as above will be described.

[0082] Figure 10 It is a perspective view showing the male connector 2 and the needleless interface 200 as the female connector before connectio...

Abstract

The lock mechanism includes: a shield (20) disposed so as to surround the male part (10) and into which the female connector (100) is inserted; and a single lock lever of an elastically displaceable cantilever support structure. (30). The locking lever (30) is configured such that its free end (30a) is on the front end side of the male component (10) and its fixed end (30b) is on the base end side of the male component (10), and its length direction is aligned with the male component (10). The shaped parts (10) are approximately parallel. The locking lever (30) has a pawl (34) engaged with the female connector (100). The operation arm (35) protrudes from the surface of the lock lever (30) on the side opposite to the male member (10), and extends to the fixed end (30b) side. The locking lever (30) is elastically displaced in such a way that if a pressing force is applied to the front end (35a) of the operating arm (35) in the direction of the male part (10), the pawl (34) moves away from the male part (10). ).

Description

technical field [0001] The present invention relates to a male connector provided with a locking mechanism for maintaining the connection state of the male connector and the female connector. Background technique [0002] When infusion or blood transfusion is performed on a patient, or extracorporeal blood circulation is performed during surgery, it is necessary to form a path (transfer line) for transporting a liquid such as a medical solution or blood. The transfer line is generally formed by connecting containers, various instruments, liquid delivery pipes, and the like. In addition, when injecting the medical solution administered to the patient into the medical solution bag (container), it is necessary to connect the medical solution bag and the syringe, and the like. In this way, a male connector and a female connector are used to detachably connect different components to each other. [0003] As an example of a female connector used for this purpose, a needle-less p...
