Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical oxygen equipment technology, specifically to a medical oxygen inhalation tube connector. Background Technology
[0002] A medical oxygen tubing assembly is a medical device used to administer pure oxygen or oxygen-containing gas to patients. It typically includes a medical oxygen tubing, a nasal cannula or mask connector, a humidification bottle, and an oxygen pressure gauge. The medical oxygen tubing connects the nasal cannula or mask connector to the oxygen pressure gauge connector on the humidification bottle. Oxygen is humidified in the humidification bottle and then delivered through the tubing to the nasal cannula or mask connector for inhalation. In existing products, the connection between the oxygen pressure gauge connector and the medical oxygen tubing is as follows: the connector is a rigid tube, and the tubing is directly inserted into it. This connection method presents several problems in practice: family members need to manually insert the tubing each time the patient uses the oxygen, especially in winter when the tubing hardens due to low temperatures, making insertion and removal difficult; sometimes, due to unstable connection, the tubing can easily come loose and fall off during use. Utility Model Content
[0003] To address the above shortcomings, this utility model provides a medical oxygen inhalation tube connector, solving the technical problems of difficult insertion and removal of medical oxygen inhalation tubes and oxygen inhalation tube connectors, as well as their tendency to fall off.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting clamping cavity is provided inside the oxygen inhalation tube connector port, and a connecting tube is disposed within the connecting clamping cavity, communicating with the oxygen pressure gauge connector port. The end of the connecting tube is tapered, forming a tapered insertion structure. An oxygen inhalation tube compression device is provided within the connecting clamping cavity; the oxygen inhalation tube compression device is used to compress the medical oxygen inhalation tube radially, thereby achieving compression of the medical oxygen inhalation tube.
[0006] Optionally, a tapered gasket is provided at the end of the connecting tube to improve the tightness of the tapered plug structure.

[0008] Optionally, it also includes a compression screw, which is movably disposed on the upper part of the telescopic compression block, with its lower end pressing against the telescopic compression block and its upper end passing through the connector body and having an end portion disposed outside the connector body.
[0009] Optionally, a raised ring is provided on the connection end side of the medical oxygen inhalation tube and the connecting tube; the radial compression of the telescopic compression block acts on the raised ring, causing the medical oxygen inhalation tube to be axially displaced along one side of the connecting tube.

[0021] like Figure 1 As shown, a medical oxygen tubing connector has a medical oxygen tubing 5 connected to its right side and an oxygen pressure gauge 2 connected to its left side via an oxygen pressure gauge connector 3. Gas flows through a humidification bottle 1, passes through the oxygen pressure gauge 2, and then flows into the medical oxygen tubing 5 through this connector. Figures 2-3As shown, in the first embodiment of this utility model, a connector body 4 is provided. An oxygen pressure gauge connector connection port 12 is provided on the left side of the connector body 4, and an oxygen inhalation tube connection port 23 is provided on the right side. A connection clamping cavity 8 is provided inside the oxygen inhalation tube connection port 23, and a connecting tube 15 is provided inside the connection clamping cavity 8. The connecting tube 15 communicates with the oxygen pressure gauge connector connection port. In this embodiment, the end of the connecting tube 15 is tapered to form a tapered insertion structure. In this embodiment, the following scheme is adopted: a tapered gasket 9 is provided at the end of the connecting tube 15. The tapered gasket 9 can be made of silicone or rubber to improve the connection tightness of the tapered insertion structure. An oxygen tube squeezing device is provided inside the connecting clamping cavity 8. This device is used to squeeze the medical oxygen tube 5 radially to achieve compression. In this embodiment, one device is provided at the upper and lower parts respectively to achieve compression. In some embodiments, multiple oxygen tube squeezing devices can be provided. The existing medical oxygen tubes 5 generally have thickened walls at the ends, which facilitates the application of higher squeezing forces and improves the compression and fixing effect. The compression structure diagram is shown below. Figure 4 As shown. The principle of this utility model is as follows: by setting a conical insertion structure to connect with the medical oxygen tubing 5, the connection efficiency is improved and the intensity of personnel operation is reduced. By employing an oxygen tubing compression device, the medical oxygen tubing 5 is pressed and fixed. During the insertion and removal operation of the medical oxygen tubing 5, the oxygen tubing compression device has telescopicity (using a spring in this embodiment), which improves the smoothness of operation. To improve the reliability of the oxygen tubing compression device, the following scheme is adopted in this embodiment: The oxygen tubing compression device includes a movable hole 20 provided on the connector body 4. A telescopic compression block 21 is provided in the movable hole 20. The cross-section of the telescopic compression block 21 is T-shaped, and a spring groove 22 is provided from top to bottom in its middle part. A compression spring 17 is provided in the spring groove 22. The compression spring 17 continuously compresses the telescopic compression block 21 along the direction of the medical oxygen tubing 5. The oxygen tubing compression device can be provided with two structures: such as... Figure 2 As shown, the first structure also includes a compression screw 6 at the telescopic compression block 21. The compression screw 6 is movably disposed on the upper part of the telescopic compression block 21, with its lower end pressing against the telescopic compression block 21 and its upper end protruding from the connector body and having an end portion disposed outside the connector body 4. In use, rotating the compression screw 6 causes it to rise and fall, thereby pressing the telescopic compression block 21 downwards, improving the compression effect of the telescopic compression block 21 on the medical oxygen tubing 5, and improving the connection firmness. The only difference of the other oxygen tubing compression device disposed at the lower part is that it does not have the compression screw 6 at its telescopic compression block 18, that is, the telescopic compression block 18 relies entirely on the compression spring 17 to achieve telescopic movement.
[0022] As a second implementation scheme for tightening the medical oxygen inhalation tube 5:
[0023] like Figures 2-3 The structure shown has a raised ring 19 at the end of the medical oxygen tube 5. The radial compression of the telescopic compression block 21 acts on the raised ring 19, causing the medical oxygen tube 5 to move axially along one side of the connecting tube. This can improve the tightness of the compression between the medical oxygen tube 5 and the conical gasket 9, prevent air leakage, and also have the effect of locking the medical oxygen tube 5.
[0024] Optionally, a flexible sealing sleeve 14 is provided at the oxygen pressure gauge connector connection port 12. One end of the flexible sealing sleeve 14 is connected to the connector body 4, for example, by adhesive bonding. One end of the connecting pipe 15 is disposed inside the flexible sealing sleeve 14. The flexible sealing sleeve 14 is used to connect to the oxygen pressure gauge connector 3 and is pressed and sealed by the clamp 11. In this embodiment, a concave ring 13 is provided at the oxygen pressure gauge connector connection port 12, and the clamp 11 is placed inside the concave ring 13. Then, an operating hole 10 is provided on one side of the concave ring 13 to allow the tightening bolt 7 of the clamp 11 to pass through for easy operation.
