Detailed Description

In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" in the specification should be interpreted broadly, and may be, for example, a fixed connection, a detachable connection, or an integral connection; the connection can be mechanical connection or electric connection, and also can be a combination of mechanical connection and electric connection; the electronic components can be installed by using a circuit of a lead, and can also be designed by using a simplified circuit board in modes of integration and the like. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific applications.

Fig. 1 and 2 provide a length-adjustable three-way pipe, which comprises at least a first pipe 100, a second pipe 200 and a third pipe 300, wherein the first pipe 100 and the second pipe 200 are coaxially arranged in the same size in an initial state, and the third pipe 300 is communicated to the connection part of the first pipe 100 and the second pipe 200, is not coaxial with the first pipe 100 and the second pipe 200 in the axial direction, and is in a roughly T-shaped structure. In use, one of the tubes is connected to the medical vaporizer, one tube is connected to the breathing apparatus, and the remaining tube is connected to a sheath provided in advance of the tracheotomy position of the patient. In principle, the first tube 100, the second tube 200 and the third tube 300 can achieve the three connection functions, but preferably, in order to prevent a series of problems such as water and trachea blockage caused by condensed water generated by condensation of the gas containing water vapor flowing from the atomizer when entering the three-way tube, the gas introduced into the atomizer from the third tube 300 is recommended to enter the position communicated with the tracheotomy sheath of the patient, and some special structures for preventing the condensed water and water-proof beads from flowing into the first tube 100 and the second tube 200 are arranged on the third tube 300, and the first tube 100 and the second tube 200 are arranged in a telescopic structure, during the use, the open end of the first tube 100 or the second tube 200 can be arranged in a mode of deviating from the axis thereof by the telescopic structure so as to form a backflow bay structure at the deviated part, here again, the design is such that condensate is stored to prevent it from flowing into the patient's trachea.

In a conventional T-tee, where two tubes are coaxially arranged and the axis of the other tube is non-coaxial with the axes of the first two tubes, the coaxial axes of the first tube 100 and the second tube 200 can be referred to as a first axis L1, and the axis of the third tube 300 can be referred to as a second axis L2, then the first axis L1 is non-coaxial with the second axis L2. For convenience of describing the flowing state of gas or other fluid in the pipeline, the three-way pipeline is assumed to be placed on the ground, and the plane of the two-dimensional T-shaped image formed by the first axis L1 and the second axis L2 is parallel to the ground or horizontal plane. This state is characterized by the fact that the three-way tube lies flat on the ground, on a table top or on a flat body surface of the patient during use, depending only on the effect of gravity. The gas with water vapor flowing out of the atomizer flows in the direction parallel to the ground, when the water vapor therein is condensed, the water drops fall along the vertical and ground direction due to the gravity, that is, the falling direction of the water drops is vertical to the plane of the first axis L1 and the second axis L2, in this case, the condensed water will be accumulated in the half sides of the three pipes close to the ground, in the case that the condensed water is accumulated in the first pipe 100 or the second pipe 200 in a large amount, the accumulation range of the condensed water will gradually approach the port of the first pipe 100 and then enter the sheath part of the tracheal incision connected with the port, and the resistance to the condensed water entering the tracheal incision of the patient comes only from the friction between the fluid and the pipe wall and the surface tension of the condensed water itself. Therefore, in order to prevent the condensed water from entering the tracheal incision of the patient, the first pipeline 100 and the second pipeline 200 are arranged to be of a telescopic structure, the telescopic structure can be realized by adopting a corrugated pipe structure, when the first pipeline 100 is bent, the axis of the first pipeline can deviate from the first axis L1 and extend towards the direction far away from the ground, and therefore a slope-shaped structure that the condensed water slides towards the ground is formed.

Considering that the patient may be using the device in a nearly flat position, if the third tube 300 is rigidly connected to the first and second tubes 200, the tee-tube T-shaped structure can assume a possible position of the tee on the patient's body driven by the patient or other external force, i.e. the third tube 300 is placed against the patient's body away from the other port connected to one end of the first tube 200, thereby supporting the first tube 200 on the surface of the patient's body, while the first tube 200 is actually in an elevated position compared to the patient's endotracheal tube sheath, if condensation occurs in the first tube 200, it will easily enter the patient's trachea due to gravity, causing water choking, particularly if the first tube 200 is provided in a softer, stretchable structure, which more easily forms a first ramp-like shape extending down the patient's trachea along the elevated end of the third tube 300 away from the patient's body A conduit 100. Therefore, a rotation part 400 is provided at a connection portion of the third duct 300 and the first and second ducts 200. To accomplish the connection of the first, second and third conduits 300, the rotary part 400 also has a generally T-shaped configuration having three connection ends, referred to as a first connection end 410, a second connection end 420 and a third connection end 430, for connection to the three conduits, wherein the opening axis of the third connection end 430 is arranged to be non-parallel to an axis coaxial with the first and second connection ends 420, preferably, perpendicular to the two axes, for convenience of alignment against the shape arrangement of the three conduits.

In the case of using the rotating part 400 for connection, preferably, the first pipe 100, the second pipe 200 and the third pipe 300 may be separately provided, that is, the three pipes are detachably connected to the rotating part 400 to form an integral structure of the tee. Preferably, the third pipe 300 is connected to the third connection end 430 to introduce moisture for wet skid into the first pipe 100 and the second pipe 200. And preferably, in order to prevent the operator from incorrectly associating the pipes with the connection ends, at least the side walls near the connection ports of the third connection end 430 and the third pipe 300 are respectively provided with corresponding auxiliary marks, for example, the two positions are respectively marked with the number 3 or words such as "wet end" by printing or etching. In other embodiments, where only the outer wall near the location of the opening of the third connection end 430 is provided with auxiliary markings, such embodiments take into account that the operator may use the tubes of other typical humidifiers on the market as the third tube 300.

In general, the connection functions of the first connection end 410 and the second connection end 420 may be used interchangeably, i.e. the first conduit 100 for connecting to the breathing apparatus and the second conduit 200 for connecting to the endotracheal intubation sheath of the patient may be connected to the first connection end 410 and the second connection end 420, respectively, at will. Preferably, in order to facilitate management of the insertion manner of the pipes and guiding operation of the operator, corresponding auxiliary marks are also respectively provided at the connection opening portions of the first connection end 410 and the first pipe 100 and the connection opening portions of the second connection end 420 and the second pipe 200, for example, numerical values 1 and 2 or words such as "trachea" and "ventilator" are used to indicate the insertion direction of the operator.

The three pipes and the three connection ends may be connected by a snap connection, and specifically, the first pipe 100, the second pipe 200, and the third pipe 300 are connected to the outer side surface near the opening of the rotary part 400, and the first flange 110 is provided to protrude outward at a position avoiding the position where the auxiliary mark is provided, and the first flange 110 is formed in an annular structure around the circumferential surface of the opening of the pipe. The inner side surfaces of the openings of the first coupling end 410, the second coupling end 420 and the third coupling end 430 are formed to protrude inward in such a manner as to match the length of the outward protrusion of the annular first flange 110 provided at the three pipe opening portions to form a second flange 411. At least one of the pipes or the connecting ends is made of a material which is soft or allows slight deformation, for example, made of PVC, rubber, and the like. Taking the first pipe 100 as an example, when an operator operates the first pipe 100 to connect to the first connection end 410 in a plugging manner, the first flange 110 interferes with the second flange 411, and since the first pipe 100 or the first connection end 410 is made of a soft or slightly deformable material, the first flange 110 is pressed through the second flange 411 so that the first pipe 100 can move further to the depth of the first connection end 410. In this arrangement, the diameter of the first conduit 100 is configured to be slightly smaller than the opening size of the first connection end 410, and the other conduits and connection ends are arranged similarly. In other embodiments, the pipe diameter of the pipe may be set larger than the size of the opening of the connection end, except that the first flange 110 at the opening end of the pipe is disposed in a manner of protruding inward on the inner side wall of the opening, and the second flange 411 at the connection end is disposed in a manner of protruding outward on the outer side wall of the opening.

Preferably, in order to limit the depth of the first pipe 100 after being inserted into the first connection end 410, a step structure 413 is provided at the deep part of the first connection end 410 away from the opening thereof, and the step structure 413 reduces the caliber of the first connection end 410 to a size value consistent with the caliber of the first pipe 100 or slightly smaller, so that the first pipe 100 cannot move forward after contacting the step structure 413, and similarly, other pipes and connection ends may be provided in a similar structure. Preferably, after the first pipeline 100 is limited by the step structure 413, a certain reserved space is formed between the first flange 110 and the second flange 411 by presetting the positions of the two, a sealing gasket 412 is arranged in the reserved space, and an interference fit is formed between the sealing gasket 412 and the reserved space, so that gas leakage can be further prevented, and other pipelines are arranged similarly.

To enable the third pipe 300 to follow the third connection end 430 in a rotational movement about the first axis L1, the first connection end 410 and the second connection end 420 are rotatably connected to the third connection end 430 by a rotational bearing 440. Specifically, the first and second connection ends 410 and 420 are configured in a substantially cylindrical structure, and the third connection end 430 is configured in a T-shaped structure having two rotation bearings 440 at both ends thereof, which are symmetrical along the second axis L2, and a pipe structure along the second axis L2, wherein the first and second connection ends 410 and 420 are connected to the third connection end 430 with two symmetrically disposed rotation shafts, respectively.

It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the utility model. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
