But it needs two hands to bind, so it is somewhat inconvenient in use. UTILITARY MODEL CONTENT

[0004] The utility model solves the technical problem that the joint of oxygen inhalation tube is easy to fall off in use, and further affects the normal oxygen inhalation of patient.

[0005] To solve the above technical problem, the technical scheme adopted by the utility model is:

[0006] An anti-drop oxygen inhalation tube includes a sleeve. The inner wall of the sleeve is conical, corresponding to the shape of the outlet tube of an oxygen inhaler. A locking rod is provided through the sleeve, perpendicular to the axis of the sleeve. The locking rod includes a cylindrical sliding part and a cylindrical locking part fixedly connected axially to one end of the sliding part.

A sealing gasket with a central opening is fixedly connected to the end of the sleeve with a smaller inner diameter. An oxygen delivery tube is fixedly connected to the end of the sleeve near the sealing gasket. The oxygen delivery tube communicates with the central opening of the sealing gasket. After the outlet tube is inserted into the sleeve, the locking part locks onto the flange on the outlet tube, and the sealing gasket presses against the outer end of the outlet tube.

[0007] Furthermore, the distance between the generatrix of the locking part near the center of the sleeve and the center of the sleeve is L1, the outer radius of the flange of the air outlet pipe is R, and the radius of the circle where the bottom of the groove of the air outlet pipe is located is r, then r < L1 < R; the distance between the generatrix of the sliding part 3 near the center of the sleeve 2 and the center of the sleeve 2 is L2, then L2 > R.

[0008] Furthermore, the sliding part and the locking part are coaxial, and the sliding part and the locking part are connected by a conical transition part.

[0009] Furthermore, one end of the sliding part extends out of the sleeve, and a spring is provided outside the sleeve for applying an outward pulling force to the sliding part.

[0010] Furthermore, there are at least two locking rods arranged in parallel, the distance between adjacent locking rods is equal to the distance between adjacent grooves on the air outlet pipe, and the sliding parts of adjacent locking rods face opposite directions.

[0011] Furthermore, the sleeve is connected to a nut via a thread at one end corresponding to the sealing gasket, the oxygen tubing is fixedly connected to the outside of the nut, the nut is fixedly connected to the outside of the sealing gasket, and the nut has a through hole at its center that connects the oxygen tubing and the center hole of the sealing gasket.

[0012] Furthermore, both the sleeve and the locking rod are made of metal, and the sealing gasket is made of elastic silicone.

[0013] Furthermore, a pressure plate is fixedly connected to the outer end of the sliding part, and the spring is disposed between the pressure plate and the sleeve, with the two ends of the spring abutting against the sleeve and the pressure plate respectively.

[0014] The positive effects of this utility model are:

The locking rod and the sleeve are elastically connected by a spring, and a pressure plate is provided outside the locking rod. The thumb and forefinger press the pressure plate, then the sleeve is placed over the outlet tube of the oxygen inhalation tube. Releasing the sleeve causes the transition part to move the sleeve forward under the spring's action, and the locking part then enters a groove on the canister, connecting the outlet tube and the oxygen inhalation tube. This invention can be operated with one hand. Because the sleeve and tube are connected by a locking part that passes through the groove and engages with a flange on one side of the groove, and because the sleeve, tube, and locking part are all rigid components, the sleeve and tube will not loosen even when the oxygen inhalation tube is subjected to tension.

[0021] The shape of the outlet tube 13 of the oxygen inhaler in the ward is as follows Figure 4 As shown, it includes a tube body 1, and the surface of the tube body 1 is provided with three annular flanges 10. There are annular grooves 9 between adjacent flanges 10. The outer diameter of the flanges 10 decreases from left to right, so that the outer circles of the flanges 10 are on the same conical surface.

[0022] Example 1

[0023] like Figures 1 to 3As shown, an anti-drop oxygen inhalation tube includes a cylindrical sleeve 2 made of 304 stainless steel. The inner wall of the sleeve 2 is conical, corresponding to the conical surface of the flange 10 of the outlet pipe 13. A locking rod 12 is provided through the sleeve 2, perpendicular to the axis of the sleeve 2. The locking rod 12 includes a cylindrical sliding part 3 and a cylindrical locking part 11 axially fixed to the inner end of the sliding part 3. The diameter of the locking part 11 is larger than the diameter of the sliding part 3. The sliding part 3 and the locking part 11 are coaxial and are connected by a conical transition part. In actual production, the sliding part 3, the transition part, and the locking part 11 are integrally formed and made of stainless steel.

[0024] The sliding part 3 is slidably connected to the sleeve 2. A sliding hole 14 is provided through the sleeve 2's wall. The locking part 11 is located within the sliding hole 14 and slidably engages with the sleeve 2. The distance between the generatrix of the locking part 11 near the center of the sleeve 2 and the center of the sleeve 2 is L1. The outer radius of the flange 10 on the air outlet pipe 13 is R, and the radius of the circle containing the bottom of the groove 9 is r, satisfying r < L1 < R. The distance between the generatrix of the sliding part 3 near the center of the sleeve 2 and the center of the sleeve 2 is L2, satisfying L2 > R.

[0025] The sleeve 2 has a centrally located sealing gasket 8 fixedly connected to its right end, which has a smaller inner diameter. The sealing gasket 8 is made of silicone. The right end of the sleeve 2 is connected to a nut 7 by threads. The nut 7 is made of hard plastic. An oxygen delivery tube 6 is fixedly connected to the right side of the nut 7. The nut 7 is bonded to the right side of the sealing gasket 8. The nut 7 has a through hole in its center that connects the oxygen delivery tube 6 and the central hole of the sealing gasket 8.

[0026] The working process of this utility model is as follows:

[0027] 1. Push the sliding part 3 inward to align the sliding part 3 with the flange 10, and insert the tube 1 into the sleeve 2 along the axial direction. Since L2>R, there is a gap between the sliding part 3 and the flange 10 along the radial direction of the sleeve 2, so the tube 1 can be smoothly inserted into the sleeve 2.

[0028] 2. Pull the sliding part 3 outward to engage the locking part 11 with the groove 9, and at the same time, the locking part 11 is locked onto the flange 10. During this process, due to the action between the flange 10 and the conical transition part, the sleeve 2 will be pulled to the left until the locking part 11 is locked onto the flange 10, the sealing gasket 8 is compressed, and thus pressed against the right end of the tube body 1, realizing the connection between the oxygen delivery tube 6 and the outlet tube 13.

[0029] Since the sleeve 2 and the tube 1 are connected by a locking part 11 that passes through the groove 9 and is engaged with the flange 10, the sleeve 2, the tube 1, and the locking part 11 are all rigid components. Even if the oxygen delivery tube 6 is subjected to tension, the sleeve 2 and the tube 1 will not loosen. The sleeve 2, the tube 1, and the locking part 11 are kept in a resistive state by the elasticity of the sealing gasket 8 to prevent loosening.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that:

[0032] One end of the sliding part 3 extends out of the sleeve 2, and a spring 5 is provided outside the sleeve 2 to apply an outward pulling force to the sliding part 3.

[0033] Under the pull of the spring 5, the position of the locking part 11 can be kept unchanged, thereby preventing its axial movement from causing the tube body 1 to fall out of the sleeve 2.

[0034] Example 3

[0035] The difference between this embodiment and Embodiment 2 is that:

[0036] The locking rods 12 are arranged in three parallel groups, with two rods in each group located on the upper and lower sides of the tube body 1. The distance between two adjacent groups of locking rods 12 is equal to the distance between adjacent grooves 9, and the sliding parts 3 of two adjacent groups of locking rods 12 face opposite directions. A pressure plate 4 is fixedly connected to the outer end of the sliding part 3, and a spring 5 is disposed between the pressure plate 4 and the sleeve 2, with both ends of the spring 5 abutting against the sleeve 2 and the pressure plate 4, respectively.

[0037] In use, press the two pressure plates 4 inward with your thumb and forefinger, then put the sleeve 2 over the tube body 1, and then release it. Under the action of the spring 5, the transition part moves the sleeve 2 to the left, and then the locking part 11 enters the groove 9, realizing the connection between the air outlet tube 13 and the oxygen delivery tube 6. This utility model can be operated with one hand in use, and the connection is quick and reliable.

[0038] The above-described embodiments are detailed and specific, illustrating preferred embodiments of the present utility model. They are only used to illustrate the technical ideas and features of the present utility model, with the aim of enabling those skilled in the art to understand the content of the present utility model and implement it accordingly. However, they are not limited to the present utility model, and the patent scope of the present utility model cannot be limited by this embodiment alone. That is, any equivalent changes or modifications made to the spirit disclosed in the present utility model, without departing from the structure of the present utility model, such as local improvements within the system and modifications or transformations between subsystems, are still within the patent scope of the present utility model.
