Description

Technical Field

[0001] The utility model relates to the field of medical gas supply equipment, in particular to a medical gas terminal plug. Background Art

[0002] The medical gas terminal plug is a dedicated connecting part for connecting the medical gas terminal. It is gas-specific. Medical gas terminal plugs of different gas types cannot be mixed to ensure gas safety. When the medical gas terminal plug is in use, its insertion end can be quickly connected and disconnected with the medical gas terminal, while the other end of the medical gas terminal plug is connected to the gas supply equipment.

[0003] Usually, small gas-using equipment such as buoy-type oxygen inhalers are directly installed and connected to the medical gas terminal plug in the form of threaded connection. Therefore, when using, you can directly hold the gas-using equipment and insert the medical gas terminal plug into the medical gas terminal for use. For large gas-using equipment such as ventilators, they are usually connected to the pagoda connector on the medical gas terminal plug in the form of a hose connection. When in use, you need to hold the medical gas terminal plug in your hand and insert it into the medical gas terminal. Due to the limited placement of the gas-using equipment, the hose may sometimes bend / fold, causing poor ventilation, affecting the normal use of the gas-using equipment. Utility Model Content

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Reference Figure 1 The utility model discloses a medical gas terminal plug, comprising a connector 2, a plug connector 5 and a connecting portion 8.

[0025] A group of air channels 6 are arranged through the connector 2 , and the air channels 6 are defined to have a first end and a second end opposite to each other, wherein the connecting portion 8 is arranged and connected to the second end of the air channels 6 .

[0026] The connecting portion 8 and the connecting body 2 can be fixedly connected, such as by welding or integral molding; the connecting portion 8 and the connecting body 2 can also be detachably connected, such as the outer wall of one end of the connecting portion 8 is threadedly connected to the inner wall of the airway 6, or the connecting portion 8 has an internal thread and is screwed on the connecting body 2, or the connecting portion 8 and the airway 6 are connected by plugging and unplugging, etc.

[0027] The connector 5 is used for plugging and unplugging connection with the medical gas terminal. One end of the connector is provided with a proprietary profile matching the medical gas terminal, and the other end is rotatably connected to the second end of the airway 6 to introduce the gas output by the medical gas terminal into the airway 6; and the function of the connecting pipe 8 is to connect the gas-using equipment and transport the gas output along the first end of the airway 6 to the gas-using equipment.

[0028] In order to ensure the airtightness between the connector 5 and the air duct 6 , the sealing ring 3 is sealed between the outer wall of the connector 5 and the inner wall of the air duct 6 , and the sealing ring 3 can be embedded in the outer wall of the connector 5 or the inner wall of the air duct 6 .

[0029] Among them, there is a certain angle between the axis of the connector 5 and the axis of the connecting pipe 8, so that when the connector 5 is horizontally inserted into the medical gas terminal, the connecting pipe 8 faces downward, that is, the angle between the axis of the connector 5 and the axis of the connecting pipe 8 can be an acute angle, a right angle or an obtuse angle.

[0030] Reference Figure 1 In one embodiment, the medical gas terminal plug is a pistol-type structure, including a gun barrel portion and a gun handle portion, wherein the gun barrel portion is assembled by a connector 2 and a connector 5, and the gun handle portion includes a pipe connecting portion 8.

[0031] Among them, a concave-convex limiting structure is provided between the outer wall of the connector 5 and the inner wall of the airway 6 to limit the connector 5 from being pulled out of the airway 6. It is easy to understand that the limiting structure may include an annular groove 7 provided on either the outer wall of the connector 5 or the inner wall of the connector 2, and at least one group of limiting members 4 provided on the other. By inserting the at least one group of limiting members 4 into the annular groove 7, the connector 5 can be limited to prevent the connector 5 from falling out of the airway 6.

[0032] In this embodiment, refer to Figure 1 The annular groove 7 is formed on the outer wall of the connector 5 , and the limiting member 4 is a screw installed on the connector 2 . The screw passes through the side wall of the airway 6 and extends into the annular groove 7 .

[0033] In addition, in one embodiment, a pagoda joint 80 is further provided on the connecting pipe portion 8, and the hose 10 is sleeved and sealed on the pagoda joint 80. Since the inner wall of the hose 10 is stretched and deformed by the pagoda joint 8 to form a seal, the hose 10 is not easy to fall off.

[0034] In order to further enhance the connection strength between the connecting portion 8 and the hose 10, a set of sheaths 9 are further provided on the connecting portion 8, and the hose 10 is clamped between the inner wall of the sheath 9 and the outer wall of the pagoda connector 80, wherein a through hole is provided on the sheath 9, and the connecting portion 8 is passed through the through hole, and the inner diameter of the through hole is not greater than the maximum outer diameter of the pagoda connector 80, which can prevent the sheath 9 from detaching from the connecting portion 8.

[0035] In addition, refer to Figure 1 The connector 2 also has an identification portion 1 to mark parameter information of the medical gas terminal plug and / or information of the gas being transported, thereby ensuring the specificity of each set of medical gas terminal plugs.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
