Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a retractable water accumulation-proof breathing tube of a ventilator. Background Art

[0002] Currently, ventilators are generally used in conjunction with humidifiers to humidify the air and reduce irritation to the patient's nasal cavity. However, water will accumulate inside the breathing tube after using it for a period of time, so a retractable anti-water accumulation breathing tube is needed to collect the accumulated water.

[0003] For example, a retractable anti-water accumulation breathing tube for critical care ventilator disclosed in application No. 202022533935.X comprises trachea 1 and trachea 2, the inner sides of the trachea 1 and trachea 2 are detachably connected with a water accumulation structure, the water accumulation structure is U-shaped and integrally formed, a convex bulge is also provided at the bottom of the inner end of the water accumulation structure, the convex bulge is integrally formed with the water accumulation structure and is provided with a corresponding cavity, a sleeve is also provided at a vertical position on one side of the water accumulation structure, the sleeve is cylindrical and fits with the outer wall of the water accumulation structure, the top of the sleeve is open and the bottom is closed, an annular storage tank is provided inside the sleeve, a drain pipe is provided on one side of the bottom end of the sleeve, and a hanging structure is provided on the inner side of the water accumulation structure. The utility model can use the convex bulge at the bottom of the U-shaped water accumulation structure to deposit accumulated liquid, and can be replaced as needed, with low cost, convenient for disinfection, cleaning and reuse, or disposable use.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although the U-shaped water accumulation structure can use the convex hump at the bottom to deposit the accumulated liquid, and can be replaced as needed, the cost is low, and it is easy to disinfect and clean for reuse, or it can be used once. However, this patent does not have an automatic drainage function. When the water pipe is full, medical staff needs to drain it manually. If it is not drained in time, the accumulated water will overflow into the breathing tube, affecting the patient's normal breathing, which is not conducive to people's use. Utility Model Content

[0041] Example 3

[0042] Reference Figure 1-4 , which is the third embodiment of the utility model, and this embodiment is based on the above two embodiments.

[0043] Both sides of the rear side of the inner cavity of the control box 201 are fixedly connected with slide rails, the inner cavity of the slide rails is slidably connected with sliders, and the bottom of the front side of the slider is fixedly connected to the control rod 205.

[0044] Specifically, the slide rail and the slider can cooperate with the control rod 205 to prevent the threaded sleeve 204 from rotating, thereby improving its stability during movement.

[0045] A cleaning plate is fixedly connected to the front side of the water inlet housing 102 by means of bolts, and the surface of the connecting pipe 103 is movably connected to the frame 101 by means of a second bearing.

[0046] Specifically: the cleaning plate can facilitate the staff to clean the inner wall of the water inlet shell 102, and the second bearing can enable the connecting pipe 103 to rotate.

[0047] A liquid level sensor 5 is provided on the right side of the top of the water storage tank 105 , and the bottom of the liquid level sensor 5 penetrates into the inner cavity of the water storage tank 105 .

[0048] Specifically: the water level in the water tank 105 can be detected by the liquid level sensor 5 to prevent the water in the water tank 105 from overflowing due to excessive water accumulation.

[0049] A liquid level observation window is provided on the front side of the water storage tank 105, and both sides of the water inlet shell 102 are connected to the connecting pipe 103 through a rotating joint.

[0051] The working principle of the utility model is as follows: the frame 101 is fixed to one side of the bed through the cooperation of the strong magnet 108, the mounting plate 107 and the connecting rod 106. When the patient turns over during sleep, the weight of the water storage tank 105 causes the water inlet shell 102 to rotate through the rotating joint, ensuring that the water storage tank 105 always maintains a vertical downward state to avoid overflow of accumulated water. The accumulated water in the water storage tank 105 is detected by the liquid level sensor 5. When there is too much accumulated water in the water storage tank 105, the motor 202 is turned on, and the motor 202 cooperates with the screw 203 to drive the threaded sleeve 204 and the control rod 205 to move. The control rod 205 moves to mobilize the push rod 206 to move, and the push rod 206 moves to squeeze the block 211, and the block 212 is blocked. After being squeezed, 11 drives the pressure rod 210 and the movable plate 208 to move, and the movable plate 208 moves to stretch the tension spring 209, and at the same time, the blocking block 211 enters the inner cavity of the water storage tank 105, and the accumulated water in the water storage tank 105 is discharged to the water receiving basin placed on the ground through the drain pipe 207. After the water storage tank 105 is drained, the motor 202 is reversed so that the top rod 206 no longer squeezes the blocking block 211, and at the same time, the tension spring 209 is reset to drive the movable plate 208 and the pressure rod 210 to move, and the pressure rod 210 moves to drive the blocking block 211 to re-enter the inner cavity of the drain pipe 207, thereby completing the automatic discharge of the accumulated water in the water storage tank 105, without the need for manual operation by medical staff, thereby avoiding the problem that the accumulated water is not discharged in time, resulting in the overflow of the accumulated water and causing damage to the patient's respiratory tract.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
