Description

Drainage structure of breathing machine pipe

Technical Field

The utility model relates to the field of medical instruments, in particular to a drainage structure of a breathing machine pipe.

Background

The ventilator tube is used for guiding the gas output by the ventilator to the patient and guiding the gas exhaled by the patient back to the ventilator. The gas output by the breathing machine needs to be humidified to be inhaled by a patient, the humidifying mode adopts a humidifying tank for humidifying, the humidifying tank heats water, and vaporized vapor is mixed with the gas output by the breathing machine to humidify the gas. The humidified gas is condensed into water by the water vapor due to the temperature drop in the transportation process of the ventilator tube. The condensed water needs to be discharged out of the ventilator tube, so that a water discharge structure is arranged on the ventilator tube.

The existing ventilator tube drainage structure is shown in fig. 1, and is a water cup arranged on a ventilator tube. The water cup is kept vertical, condensed water in the breathing machine pipe flows into the water cup for collection, the water cup is transparent, when more water is collected in the water cup, the water cup is detached to pour water, and then the water cup is reloaded to continuously collect the condensed water.

The above-described ventilator tube drainage structure has several drawbacks. Firstly, the water cup needs to be kept vertical, but in clinical practice, the water cup is difficult to ensure, if the water cup is accidentally inclined, even horizontal or inverted, the water cup cannot collect condensed water, the condensed water collected by the water cup can flow back into a pipeline, and if a patient inhales the condensed water, choking cough and other serious problems can be caused. Secondly, when the water cup is detached to pour water, condensed water still is generated in the pipeline, so that the water drips out, and the water can be received by other containers, but after all, other articles are needed, and the water pouring device is inconvenient; and after the water cup is detached, the breathing machine pipe leaks air, which is not beneficial for a patient to inhale the air output by the breathing machine pipe.

Detailed Description

The utility model is further described below with reference to the drawings and the detailed description.

As shown in fig. 2, the ventilator tube drainage structure comprises a connecting tube 1, a water cup 2, a hose 3 and a floating ball 4; the connecting pipe 1 comprises a main pipe 11 and a bypass pipe 12 connected with the main pipe 11, and two ends of the main pipe 11 are used for connecting the ventilator pipe 5; the water cup 2 is connected with the bypass pipe 12; the hose 3 and the floating ball 4 are positioned in the water cup 2, one end of the hose 3 is connected with the bypass pipe 12, the other end of the hose 3 is connected with the floating ball 4, and the floating ball 4 is provided with a drain hole 43; condensed water in the connecting pipe 1 is discharged into the water cup 2 through the hose 3 and the floating ball 4.

As shown in fig. 3, the present utility model is provided for use on a ventilator tube 5. The same as the prior art is that the water cup 2 is vertically arranged when in use, and the condensed water in the connecting pipe 1 is discharged into the water cup 2 through the hose 3 and the floating ball 4 for collection. When the collected water is more, the floating ball 4 floats upwards, the hose 3 is bent, and the condensed water is not influenced to enter the water cup 2.

If the position of the cup 2 is changed accidentally, for example, to be horizontal, the float ball 4 is still floating on the water surface as shown in fig. 4, and the water in the cup 2 cannot enter the drain hole 43, so that the water cannot flow back to the ventilator tube 5. Due to the closure of the hose 3, water cannot enter the bypass pipe 12 directly either. The floating ball 4 is inclined or even inverted, and the floating ball floats on the water surface, so that the water in the water cup 2 cannot enter the water drain hole 43. Therefore, the utility model has the effect of preventing condensate from flowing back, and is beneficial to avoiding the patient from inhaling the condensate.

The connection tube 1, the cup 2 and the float 4 may be made of plastic, and the cup 2 should be transparent so that the amount of water collected by the cup 2 can be seen. The hose 3 may be made of silicone.

Further, the present utility model preferably has a funnel-shaped shape of the bypass pipe 12, the large end of the bypass pipe 12 is connected to the main pipe 11, and the small end of the bypass pipe 12 is connected to the hose 3. The large end of the bypass pipe 12 is connected to the main pipe 11 in the sense that condensate in the main pipe 11 enters the bypass pipe 12. The small end of the bypass pipe 12 is connected to the hose 3 in the sense that the hose 3 can be smaller in diameter and more flexible.

In order to reduce the weight of the float ball 4 and facilitate its floating, it is preferable that the float ball 4 has a closed cavity 44 for reducing its weight.

The specific structure of the floating ball 4 can be as follows: the floating ball 4 comprises a floating ball shell 42 and a floating ball tube 41, the floating ball tube 41 radially penetrates through the floating ball shell 42 along the floating ball shell 42, an inner hole of the floating ball tube 41 is a drain hole 43, and a space between the floating ball tube 41 and the floating ball shell 42 is a closed cavity 44.

The specific structure of the water cup 2 can be the same as that of the prior art, namely, the water cup 2 comprises a cup cover 22 and a cup body 21, the cup cover 22 is connected with the bypass pipe 12, and the cup body 21 is in threaded connection with the cup cover 22. The rotary cup 21 is detachable. The condensed water collected can be poured off by removing the cup 21.

When the water is poured out of the cup body 21, the drain hole 43 communicates with the outside, so that air leakage occurs, and newly generated condensed water leaks. In order to solve this problem, the main pipe 11 of the present utility model preferably includes a sleeve 111 and a telescopic pipe 112, the bypass pipe 12 is connected to the sleeve 111, the telescopic pipe 112 is inserted into the sleeve 111 and is interference fit with the sleeve 111, and the telescopic pipe 112 is movable inward to close the bypass pipe 12.

With the above arrangement, the bypass pipe 12 can be simply closed, and leakage of air and water from the ventilator pipe 5 can be avoided. As shown in fig. 5, moving the bellows 112 inwardly, the bellows 112 closes the bypass tube 12 and does not affect the normal ventilation of the ventilator tube 5. At this time, the cup 21 is removed to pour water. After pouring water, the cup body 21 is put back, the extension pipe 112 is pulled outwards, and the extension pipe 112 does not close the bypass pipe 12.

The interference fit of the telescopic tube 112 and the sleeve 111 has the function of ensuring the sealing effect and avoiding the unexpected closing of the bypass tube 12 caused by the unexpected movement of the telescopic tube 112. The interference of the interference fit should be suitable, so that it is required to prevent the telescopic tube 112 from moving accidentally, and to avoid that the telescopic tube 112 is difficult to move due to the excessive interference.

The extension tube 112 should be prevented from being pulled out of the sleeve 111, for which the following arrangement can be used: the sleeve 111 has a locating inner flange 1111 thereon and the extension tube 112 has a locating outer flange 1121 thereon, the locating outer flange 1121 being in interference fit with the sleeve 111, the locating inner flange 1111 limiting the movement of the locating outer flange 1121 out of the sleeve 111.
