Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a connection structure for oxygen tubing in a ventilator. Background Technology

[0002] An oxygen fitting is a device used to connect two sets of oxygen tubing. It is an indispensable part of the medical field, providing patients with a safe and reliable oxygen supply through precise design and strict manufacturing standards.

[0003] The existing oxygen tubing connection method is a snap-fit, where the tubing is directly inserted into the required position. During use, the tubing is prone to detachment, which affects the subsequent normal use of the oxygen mask. Therefore, there is a need to provide a connection structure for ventilator oxygen tubing that can quickly and stably fix the oxygen tubing together. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for oxygen tubing in a ventilator, in order to solve the problem mentioned in the background art, where the existing oxygen tubing connection method is a snap-fit, where the tubing is directly inserted into the required position, and during use, the tubing is prone to detachment, thus affecting the normal use of the oxygen mask.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a connection structure for oxygen tubing in a ventilator, comprising:

[0007] A connecting assembly includes a fixed tube, a connecting tube, a first spring, and a movable tube; the connecting tube is sleeved on the outer surface of one side of the fixed tube, the first spring is fixed between the fixed tube and the connecting tube, and the movable tube is snapped into the inside of the fixed tube.

[0008] Furthermore, the interior of one side of the fixed tube is provided with equidistant movable grooves, and movable balls are movably connected inside the movable grooves.

[0009] Furthermore, a limiting groove is provided inside the fixed tube, and a connecting groove is provided inside one side of the connecting tube.

[0010] Furthermore, it also includes a reinforcement component, which includes a connecting sleeve, a first fixing block, a second fixing block, and a fixing frame; the connecting sleeve is sleeved on the outer surface of the other side of the fixing tube, the first fixing block is fixed on the outer surface of the fixing tube, the second fixing block is fixed on the outer surface of the connecting sleeve, and the fixing frame is fixed on the outer surface of the first fixing block.

[0011] Furthermore, a second spring is fixed inside the fixed frame, and a connecting post is fixed on the outer surface of the second spring, with the connecting post penetrating and connecting to the interior of the second fixed block.

[0012] Furthermore, a connecting hole is provided through the interior of the second fixing block, and a fixing groove is provided through the interior of the second fixing block. A rotating block is rotatably connected to the outer surface of the connecting column, and the rotating block is engaged inside the fixing groove.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model, through its designed connecting components, allows for the quick and stable connection of oxygen tubing when needed. First, the fixed tube is connected to the oxygen mask tubing, and then the movable tube is connected to the oxygen supply cylinder. The actual pulling force on the connecting tube compresses the first spring, freeing the movable ball from restriction. The movable tube is then fully inserted into the fixed tube. Releasing the force on the connecting tube, the connecting tube springs back to its original position under the elastic force of the first spring, thus confining the movable ball within the movable groove and fixing the movable tube inside the fixed tube. This design quickly and stably secures the oxygen tubing together.

[0015] II. Based on the first beneficial effect, when the fixed tube needs to be connected to the oxygen mask tubing, with the reinforcement components in conjunction, a rotational force is first applied to the rotating block to make the rotating block conform to the shape of the connecting hole. The connecting sleeve is then placed on the other side of the fixed tube, allowing the connecting post to pass through the inside of the second fixed block. A pulling force is then applied to the rotating block to move it out of the second fixed block. A rotational force is then applied to the rotating block to move it to the fixing groove. The force applied to the rotating block is then released, and under the elastic force of the second spring, the rotating block is locked inside the fixing groove. This solution allows the connecting sleeve and the fixed tube to be designed separately, thereby reducing the cost of parts replacement. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 As shown, this embodiment is a connection structure for an oxygen tubing of a ventilator, including:

[0028] The connecting assembly includes a fixed tube 11, a connecting tube 12, a first spring 13, and a movable tube 16; the connecting tube 12 is sleeved on the outer surface of one side of the fixed tube 11, the first spring 13 is fixed between the fixed tube 11 and the connecting tube 12, and the movable tube 16 is snapped into the inside of the fixed tube 11.

[0029] The fixed tube 11 is used to connect to the oxygen mask tubing. The connecting tube 12 facilitates the adjustment of the internal parts of the fixed tube 11, thereby making it easy to fix the movable tube 16 inside the fixed tube 11. The first spring 13 is used to provide elastic force so that the connecting tube 12 can move when subjected to external force and return to its original position after the external force is removed.

[0030] The interior of one side of the fixed tube 11 is provided with equally spaced movable grooves 14, and movable balls 15 are movably connected inside the movable grooves 14.

[0031] The movable groove 14 is used for the movable ball 15 to move within it, and the movable ball 15 is used to confine the movable tube 16 within the fixed tube 11.

[0032] A limiting groove 17 is provided inside the fixed tube 11, and a connecting groove 18 is provided inside one side of the connecting tube 12;

[0033] The limiting groove 17 is used to plan the space inside the fixed tube 11, so as to facilitate the guiding and fixing of the movable tube 16 inside the fixed tube 11, while the connecting groove 18 facilitates the movement of the movable ball 15 inside the connecting tube 12.

[0034] Working principle: When it is necessary to connect the oxygen pipeline, first connect the fixed tube 11 to the oxygen mask pipeline, and then connect the movable tube 16 to the oxygen supply cylinder. The actual pulling force on the connecting tube 12 compresses the first spring 13. After the movable ball 15 is unrestricted, the movable tube 16 is fully inserted into the fixed tube 11. The force applied to the connecting tube 12 is released. Under the elastic force of the first spring 13, the connecting tube 12 springs back to its original position, thereby restricting the movable ball 15 inside the movable groove 14, and then fixing the movable tube 16 inside the fixed tube 11.

[0035] This step quickly and stably secures the oxygen tubing together.

[0036] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes a reinforcing component. The reinforcing component includes a connecting sleeve 21, a first fixing block 22, a second fixing block 23, and a fixing frame 24. The connecting sleeve 21 is sleeved on the outer surface of the other side of the fixing tube 11, the first fixing block 22 is fixed to the outer surface of the fixing tube 11, the second fixing block 23 is fixed to the outer surface of the connecting sleeve 21, and the fixing frame 24 is fixed to the outer surface of the first fixing block 22.

[0037] The connecting sleeve 21 is used to connect the oxygen mask tubing to the fixed tube 11. The first fixing block 22 and the second fixing block 23 are used to connect the fixed tube 11 to the connecting sleeve 21. The fixing frame 24 is used to support and install the second spring 25.

[0038] A second spring 25 is fixed inside the fixed frame 24, and a connecting post 26 is fixed on the outer surface of the second spring 25. The connecting post 26 passes through and connects to the inside of the second fixed block 23.

[0039] The second spring 25 can quickly and easily return the connecting post 26 to its original position. The connecting post 26 is used to support and install the rotating block 28.

[0040] The second fixing block 23 has a through-hole 27 and a fixing groove 29. The outer surface of the connecting post 26 is rotatably connected to a rotating block 28, which is engaged inside the fixing groove 29.

[0041] The connecting hole 27 is used for the rotating block 28 to pass through the inside of the second fixed block 23, and the fixing groove 29 is used to receive and install the rotating block 28. The rotating block 28 is used to connect the first fixed block 22 and the second fixed block 23 together.

[0042] Working principle: When it is necessary to connect the fixed tube 11 to the oxygen mask tubing, first apply a rotational force to the rotating block 28 so that the rotating block 28 is shaped to match the connecting hole 27. Then, put the connecting sleeve 21 on the other side of the fixed tube 11 so that the connecting post 26 passes through the inside of the second fixed block 23. Apply a pulling force to the rotating block 28 to move the rotating block 28 away from the inside of the second fixed block 23. Apply a rotational force to the rotating block 28 so that the rotating block 28 moves to the fixed groove 29. Remove the force applied to the rotating block 28. Under the elastic force of the second spring 25, the rotating block 28 is locked inside the fixed groove 29.

[0043] This step allows the connecting sleeve 21 and the fixing tube 11 to be designed separately, thereby reducing the cost of replacing parts.
