Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector that can firmly connect two ports capable of transporting liquid or gas with quick and easy operation. The coupler of the present invention is
It is a plug-in type and is often used for connecting air hoses, but it is not limited to the air hose 7.

Plug-in quick-disconnect connectors are a technical component for connecting pipes, tubes, or hoses of oxygen tanks and pipes, tubes, or hoses that connect to devices that supply oxygen to patients. It is well known in It is often necessary for the patient himself to connect or disconnect the oxygen hose to the oxygen supply device.

Such couplings are often difficult to operate because of the need to have a rigid coupling to maintain the integrity of the oxygen passageway. In practice, this type of coupler is used in most cases. The @ person is a mourner who is elderly or physically weak. However, the awkwardness of attaching and detaching the coupler makes the patient uncomfortable.

In many cases, this problem is caused by frail or geriatric patients who are unable to connect the standard bayonet type connections by carefully lining up the pins on one side of the coupler with the pins on the other side of the coupler. This occurs when trying to connect vessels. Such couplings are difficult and often impossible for some patients, the most frail and the oldest.

The present invention overcomes the problems occurring in known bayonet couplings by allowing for a simpler connection of the male and female members. The wide opening of the slot in the female member allows for easy alignment of the pins extending from the male member during connection. This allows even frail patients to quickly and easily align the pins with the slots to secure the coupler members in position.

The coupler of the present invention has first and second ends, the first end configured to connect to a pipe, tube, hose, etc., and having one or more pins extending radially outwardly from a surface thereof. a generally cylindrical male member having a substantially cylindrical male member, and one end L1 configured to be able to cooperatively engage the male member and connectable to a pipe, pipe, hose, etc.; a generally cylindrical female member having an opposite end having one or more slots for receiving the pins of the male member. each slot extending approximately from the other end toward the one end but at an angle to the axis of the female member, each slot having a fixing recess;
It has an opening that widens toward the other end, and a groove that connects the fixing recess to the opening. The fixing recess is configured to fitably receive one of the pins and is provided between the groove and the fixing four part to retain the one pin in the fixing recess during connection. the groove has substantially parallel sides leading from the locking recess to the opening for guiding the one pin into the locking recess during coupling, and the opening has rounded edges; from the direction of the side of the groove to form an opening having a width larger than the groove; It has sides that extend outwardly at an angle.

The side portions of the opening are made into a linear shape 11 and expanded to form a linear side so that the side portions of the opening form a compound angular change with the linear side portion of the groove in pairs 17 with respect to the axis of the male member. It is possible to obtain an enlarged opening having a width larger than that of the portion and the groove.

As shown in FIG. 1, a coupler 10 according to the invention includes a female member 12 having a generally cylindrical shape and a male member 14 having a generally cylindrical shape. The female member 12 has a first end 16, a thread 11j 20 for connection to a hose or the like (not shown). Pipes, tubes and hoses 1! To facilitate connection of the female member 12 (not shown), an opposing flat surface 22 is provided near the end 16 to allow for gripping with a wrench or other tool. As shown in FIG. 2, an annular shoulder 24 is provided extending inwardly from the inside of the female member, 1..., z, with a gasket or washer (not shown) provided on one side. giving support for.

As shown in FIG. 1I and FIG.
It has an end 26 and a second end 28.

Threads 30 are provided on the inside of the male member near the first end 26 for connection with complementary threads on a pipe, tube, hose, etc. (not shown). The male cylindrical member 14 also has a smaller cylindrical portion 32 adjacent the second end 28, thereby forming a shoulder 34. A pair of opposing pins 36 and 38 extend radially outwardly from the surface of the cylindrical male member 14 near a shoulder 34 spaced apart from the first end 26 . An opening 40 is provided in the male member 14 to allow the flow of gas or liquid. Further, to facilitate connection of male member 14 to a threaded pipe, tube, hose, etc. (not shown), opposing flat surface 42 is provided as a gripping point for a wrench or other tool.
It is provided adjacent to the end portion 26.

Female member 12 has opposed slots 44 (one on each side of female member 12) that engage pins 36 and 38 of male member 14 during coupling.
One of each) is provided. As shown in FIGS. 1 and 2, the slot 44 has a locking recess (loc).

It is shaped to fitably engage pin 36 or 38. Recess 46 and $44 are provided to hold pin 36 or 38 within recess 46 when the two members are connected.
A lip 52 is provided between the two. The groove 48 connecting the fixing recess 46 to the opening 50 has sides 54 and 56.

or approximately parallel to each other to lead to 38. Sides 54 and 56 are spaced apart by a distance slightly greater than the diameters of pins 36 and 38 in order for the pin to easily pass through these sides without significant play. Opening 50 is defined by sides 58 and 60.

Sides 58 and 60 extend outwardly at an angle from the direction of sides 54 and 56 of #ll#48, respectively. Sides 58 and 60 are closest to each other at 62, which marks the transition from groove 48 to opening 50. From this proximal point 62, sides 58 and 60 extend outwardly to
It forms an opening that gradually becomes wider. This opening is considerably larger in its recess 64, which is sandwiched by points 66 and 68, than in point 62. Mouth 64 is considerably wider than the width of groove 48.

The female member 12 can be attached to a pipe, tube, or
The male member 14 is connected to other pipes, tubes, hoses, etc. (not shown) by threads 30. When a user attempts to connect female member 12 to male member 14, the most difficult task is to properly align pins 36 and 38 with slots 44 to connect the two members. Typically, each member will be held in the hand of the patient who wishes to connect it. When the female member 12 is engaged with the male member 14, the male member 14 engages the pin 36.

When these parts are engaged by turning in the direction of arrow 70, the pins 36 and 38 are guided from the opening 50 into the groove 48 and from the opening 48 into the fixing section 46, thereby closing the connection 17. is formed. Ideally, the width of the mouth 64 is greater than twice the width of the groove 48 (
This makes it easier for elderly or infirm patients to find alignment of pins 36 and 38 relative to slot 44, but not necessarily twice as large, for proper function. It becomes easier to connect parts together.
