Examples

As shown in fig. 1 and fig. 2, the present embodiment discloses a detachable oxygen inhalation device for tracheotomy patients, which has the technical effects of easy detachment, good fixing effect, low possibility of abrasion, and changeable oxygen flow.

Specifically, the detachable oxygen inhalation device for tracheostomy patients comprises a tracheostomy catheter 100, an oxygen inhalation tube 200 and an inner catheter 300; the oxygen tube 200 is inserted into the inner cavity of the tracheostomy tube 100 and movably and flexibly clamped with the tracheostomy tube 100, and the inner catheter 300 is inserted into the inner cavity of the oxygen tube 200 and detachably connected with the oxygen tube 200.

The oxygen inhalation tube 200 is movably and flexibly clamped with the autogenous cutting guide tube 100, so that abrasion caused by multiple times of rigid clamping is avoided; after the autogenous cutting catheter 100 is butted with the oxygen uptake pipe 200 for a plurality of times, no abrasion occurs. Therefore, the fixing device has the advantages of convenience in disassembly and assembly and good fixing effect. The inner conduit 300 is inserted into the oxygen inhalation tube 200, the inner conduit 300 is communicated with the oxygen inhalation tube 200, and the oxygen content in the inner conduit 300 is less than that in the oxygen inhalation tube 200, so that the choking of the tracheotomy patient caused by the inhalation of excessive oxygen can be effectively avoided.

In this embodiment, the flexible clamping of the oxygen inhalation tube 200 and the tracheostomy catheter 100 is realized by: the inner wall of the autogenous cutting catheter 100 is provided with a fixed ring 110, and the outer wall of the oxygen tube 200 is convexly provided with a flexible circular ring 210; the flexible ring 210 passes through the inner cavity of the fixing ring 110 and is clamped with the fixing ring 110, and the outer diameter of the flexible ring 210 is larger than the inner diameter of the fixing ring 110. Flexible ring 210 produces deformation after receiving the external force extrusion and passes the inner chamber of solid fixed ring 110, and flexible ring 210 reconversion after the application of force is ended because flexible ring 210's external diameter is greater than the internal diameter of solid fixed ring 110 for flexible ring 210 card is at the upper surface/lower surface of solid fixed ring 110, can effectively avoid oxygen tube 200 from the inner chamber slippage of autogenous cutting pipe 100. In addition, the flexible ring 210 is in flexible contact with the fixing ring 110, but not in rigid contact with the fixing ring 110, so that abrasion of the inner cavity and the outer wall of the fixing ring 110 can be effectively avoided, the practical period of the tracheostomy tube 100 can be prolonged, and inconvenience caused by replacement of the tracheostomy tube 100 is avoided.

In this embodiment, the outer diameter of the oxygen tube 200 is smaller than or equal to the inner diameter of the fixing ring 110.

In this embodiment, in order to improve the convenience of mounting and dismounting the oxygen inhalation tube 200 and the tracheostomy tube 100, the outer portion of the flexible circular ring 210 is arc-shaped. The arc-shaped arrangement facilitates the oxygen tube 200 to pass through the autogenous cutting guide tube 100, and simultaneously can also reduce the abrasion of the flexible circular ring 210 in the dismounting process, thereby effectively avoiding the oxygen tube 200 from sliding off from the autogenous cutting guide tube 100.

In this embodiment, the flexible ring 210 is made of silica gel, polyvinyl alcohol, or polytetrafluoroethylene, and those skilled in the art can select other flexible and safe medical materials according to actual situations.

In this embodiment, in order to facilitate the detachment and attachment of the oxygen tube 200 and the inner tube 300, the end of the inner tube 300 near the fixing ring 110 extends toward the tracheostomy tube 100 and protrudes out of the oxygen tube 200.

In this embodiment, according to the change of the oxygen demand of the oxygen inhalation tube 200 in different treatment stages of the tracheostomy patient, the inner wall of the oxygen inhalation tube 200 can be connected with the inner catheter 300 with different oxygen throughputs. The connection between the oxygen tube 200 and the inner conduit 300 is realized by configuring a convex first screw interface on the inner wall of the oxygen tube 200, configuring a connection ring 310 on the outer wall of the inner conduit 300, configuring a concave second screw interface on the outer wall of the connection ring 310, and connecting the first screw interface and the second screw interface by screw thread. The inner catheter 300 with different oxygen throughputs can realize different oxygen throughputs of the tracheotomy patient by configuring different types of connecting rings 310.

In this embodiment, the inner wall of the tracheostomy tube 100 is provided with a guide opening for facilitating insertion of the oxygen tube 200.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
