Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 3-10, the fastening type connection structure for the tracheal cannula and the ventilator described in this embodiment includes a ventilator connection tube 1 and a tracheal cannula connection sleeve 2 adapted to the ventilator connection tube 1, a fixing ring 3 is disposed on the tracheal cannula connection sleeve 2, at least two elastic metal clamping pieces 4 are uniformly disposed on the fixing ring 3 along the circumferential direction, one end of each elastic metal clamping piece 4 is embedded in the fixing ring 3, and a backstop clamping protrusion 5 is disposed on the ventilator connection tube 1 in cooperation with the elastic metal clamping pieces 4.
Solid fixed ring 3 is fixed through sticky mode and trachea cannula adapter sleeve 2, and when the preparation like this, earlier with elastic metal card 4 in solid fixed ring 3 injection moulding, pre-buried in solid fixed ring 3, then wait that the die sinking cooling back two is together fixed, then bond solid fixed ring 3 on trachea cannula adapter sleeve 2 again, great reduction the manufacturing degree of difficulty of whole structure.
Be provided with indent structure 301 or evagination structure on the terminal surface of solid fixed ring 3 one side at least, indent structure 301 or evagination structure are along the even many places that are provided with of circumference, when carrying out solid fixed ring 3 and trachea cannula adapter sleeve 2 bonding, can improve the reliability of adhesive linkage, avoid the condition that solid fixed ring 3 pine takes off appearing in the in-process that uses.
