Technical Field
[0001] The utility model belongs to the technical field of medical accessories, and particularly relates to an automatic drainage and collection device for condensate water in a breathing pipeline. Background Art
[0002] Mechanical ventilation has become a common means for treating critically ill patients. During the process of mechanical ventilation, in order to achieve a better airway humidification effect, the inhaled gas needs to be heated and humidified. The heated and humidified gas is very likely to generate condensate water in the relatively low-temperature environment of the ward. The harms of condensate water to patients include: generating flow velocity in the circuit, increasing the risk of man-machine confrontation; directly pouring back into the patient's airway when the air flow is too large, causing the patient to suffocate; too much condensate water will increase the occurrence of ventilator-associated pneumonia, etc.
[0003] In the prior art, a water collecting cup is usually arranged at the lowest part of the breathing pipeline to collect the condensate water in the ventilator pipeline. However, when the existing water collecting cup is in use, it cannot automatically drain the condensate water. Manual pouring not only has a delay, increasing the workload of clinical nurses, but also increases the incidence of ventilator-associated pneumonia, prolongs the hospital stay, increases the hospitalization cost and the social care burden. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides an automatic drainage and collection device for condensate water in a breathing pipeline. Through the buoyancy effect of the buoy in the condensate water, the automatic drainage of the condensate water in the liquid accumulation cup is realized, and ventilator-associated pneumonia can be effectively prevented.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an automatic drainage and collection device for condensate water in a breathing pipeline, including a liquid inlet pipe and a liquid accumulation cup. One end of the liquid inlet pipe is connected to the pipeline of the ventilator, and the other end of the liquid inlet pipe is connected to the pipeline of the patient mask. The bottom end of the liquid inlet pipe is provided with a liquid outlet, and the liquid outlet extends into the liquid accumulation cup. A one-way valve is arranged at the liquid outlet. A sealing ball, a buoy and a limiting cylinder are arranged in the liquid accumulation cup. A drainage port is arranged at the bottom end of the liquid accumulation cup. The diameter of the sealing ball is larger than the diameter of the drainage port. The sealing ball is placed on the drainage port so that a part of the bottom end of the sealing ball is embedded in the drainage port. The bottom end of the limiting cylinder is fixedly connected to the inner bottom surface of the liquid accumulation cup. The drainage port, the sealing ball and the buoy are all located inside the limiting cylinder. The buoy is connected to the sealing ball, and the buoy is located above the sealing ball. Through holes are arranged on the side wall of the limiting cylinder. A drainage pipe is connected to the bottom end of the drainage port.
[0006] Preferably, it further includes a drainage bag, and the inlet of the drainage bag is connected to the drainage pipe.
[0007] Preferably, a drain pipe is arranged at the bottom end of the drainage bag, and a valve is arranged on the drain pipe.
[0008] Preferably, the drainage bag is a transparent bag, and a scale is provided on the drainage bag.
[0009] Preferably, an exhaust hole is provided on the drainage bag.
[0010] Preferably, a handle is provided on the drainage bag.
[0011] Preferably, an anti-backflow mechanism is provided in the drainage tube.
[0012] Preferably, the anti-backflow mechanism includes a fluid guide, a support, a sealing body, and an elastic member;
[0013] The fluid guide and the support are both arranged in the drainage tube, the support is located below the fluid guide, a fluid passage for fluid to pass through is provided in the fluid guide, and two ends of the elastic member are respectively connected to the support and the sealing body. The elastic member is used to support the sealing body so that the sealing body blocks the bottom end of the fluid passage.
[0014] Preferably, an air inlet and an air outlet are provided on the liquid inlet tube, and both the air inlet and the air outlet are used for connecting to an external pipeline.
[0015] Preferably, the limiting cylinder is coaxial with the drainage port, and the sealing ball is adapted to the limiting cylinder.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] 1. For an automatic drainage and collection device for respiratory tube condensate provided by the present utility model, by arranging a sealing ball and a float, when the condensate in the liquid accumulation cup is less or there is no condensate, the sealing ball blocks the drainage port due to gravity, effectively preventing gas leakage in the respiratory tube. When the water in the liquid accumulation cup reaches a certain water level, the buoyancy of the float lifts the sealing ball, and the condensate in the liquid accumulation cup is automatically drained, which can effectively prevent ventilator-associated pneumonia. After the water flows away, the sealing ball blocks the drainage port again due to gravity.
[0018] 2. For an automatic drainage and collection device for respiratory tube condensate provided by the present utility model, by arranging a drainage bag, the condensate can be collected daily and poured once a day. The daily drainage volume can also be recorded for indirectly evaluating the humidification effect. The exhaust hole on the drainage bag exhausts gas but does not drain liquid. When the gas in the respiratory tube accidentally enters the drainage bag, the gas can be discharged through this exhaust hole to prevent the drainage bag from being affected in use due to being filled with gas.
[0019] 3. An automatic drainage and collection device for respiratory pipeline condensate provided by the present utility model is provided with anti-backflow structures with different mechanisms in both the drainage pipe and the liquid accumulation cup, which can prevent the condensate in the liquid accumulation cup from flowing back into the respiratory machine pipeline, and can also prevent the condensate in the drainage bag from flowing back into the liquid accumulation cup. These two anti-backflow structures can effectively prevent infections caused by backflow. Description of the Drawings

[0026] The following further detailed description of the present utility model is provided in conjunction with specific embodiments, so that those skilled in the art can understand the present utility model more clearly.
[0027] Embodiment 1
[0028] Refer to Figure 1-2 , this embodiment provides an automatic drainage and collection device for respiratory pipeline condensate, including:
[0029] A liquid accumulation cup 1 for collecting condensate, with a drainage port provided at its bottom end, and a drainage pipe 3 is connected to the drainage port, and the drainage pipe 3 is used for discharging the condensate in the liquid accumulation cup 1.
[0030] The liquid inlet pipe 2 is provided with an air inlet 16 and an air outlet 17, and the air inlet 16 and the air outlet 17 are used for connecting with the external breathing pipeline. The bottom end of the liquid inlet pipe 2 is provided with a liquid outlet, and the liquid outlet extends from the top end of the liquid accumulation cup 1 to the inside of the liquid accumulation cup 1, and is used for allowing the condensed water in the breathing pipeline to flow into the liquid accumulation cup 1. The joint between the pipe wall of the liquid inlet pipe 2 and the top end of the liquid accumulation cup 1 is hermetically connected.
[0031] Specifically, connect the pipeline connected to the ventilator to the air inlet 16, then connect the pipeline connected to the patient's face mask to the air outlet 17, and then place the liquid accumulation cup 1 in the lowest position. In this way, the oxygen provided by the ventilator enters the patient's breathing mask through the air inlet 16 and the air outlet 17 in sequence, and the condensed water in the pipeline can flow into the liquid accumulation cup 1 through the liquid outlet of the liquid inlet pipe 2, realizing the collection of condensed water.
[0032] Since the liquid accumulation cup 1 is prone to tilting or even inversion, or when the position of the liquid accumulation cup 1 is higher than the ventilator pipeline, the condensed water in the liquid accumulation cup 1 may flow back into the breathing pipeline. To avoid this phenomenon, in this embodiment, a check valve 18 is provided at the liquid outlet, and the check valve 18 can prevent the condensed water in the liquid accumulation cup 1 from flowing back into the liquid inlet pipe 2, improving the safety of the device. Optionally, the check valve 18 is a duckbill valve.
[0033] In addition, in order to prevent the gas in the breathing pipeline from leaking from the drainage port of the liquid accumulation cup 1, a sealing ball 4 and a buoy 5 are also provided in the liquid accumulation cup 1, and the sealing ball 4 and the buoy 5 are connected. The diameter of the sealing ball 4 is larger than the diameter of the drainage port. Due to its own gravity, the sealing ball 4 can automatically block above the drainage port to form a sealed space. According to needs, a sealing gasket adapted to the sealing ball 4 can be provided at the drainage port to effectively improve the sealing performance at the drainage port.
[0034] Specifically, when the sealing ball 4 blocks above the drainage port, the condensed water in the liquid accumulation cup 1 cannot flow out. As the condensed water continuously enters the liquid accumulation cup 1, after the condensed water in the liquid accumulation cup 1 reaches a certain liquid level height, the buoy 5 floats. At this time, the buoyancy of the buoy 5 in the condensed water can pull up the sealing ball 4, causing the sealing ball 4 to disengage from the drainage port, thereby opening the drainage port, enabling the condensed water in the liquid accumulation cup 1 to flow out through the drainage port, and effectively preventing ventilator-associated pneumonia. At the same time, the liquid level continues to drop until the sealing ball 4 blocks above the drainage port again.
[0035] That is to say, by blocking the sealing ball 4 above the drainage port, the sealing performance of the liquid accumulation cup 1 can be ensured before and after draining the condensed water. And during the process of draining the condensed water, due to the blocking effect of the condensed water, very little gas leaks through the drainage port at this time. Thus, it is possible to avoid as much as possible the gas in the breathing pipeline from leaking from the drainage port.
[0036] To prevent the sealing ball 4 from detaching from the drainage port, a limiting cylinder 6 is also provided inside the liquid accumulation cup 1. The limiting cylinder 6 covers the drainage port, and through holes are provided on the side wall of the limiting cylinder 6, allowing condensed water to freely pass through the limiting cylinder 6. The buoy 5 and the sealing ball 4 are both located inside the limiting cylinder 6, and the limiting cylinder 6 can limit the sealing ball 4 to prevent it from floating to other positions and being unable to return above the drainage port.
[0037] Among them, the limiting cylinder 6 can be coaxially arranged with the drainage port, and the sealing ball 4 is adapted to the limiting cylinder 6. The limiting cylinder 6 can restrict the space for the sealing ball 4 to float up and down, preventing the sealing ball 4 from falling to other positions.
[0038] In some other embodiments, the bottom of the liquid accumulation cup 1 can be a funnel-shaped structure, and the drainage port is located at the tip. This is beneficial for the condensed water at the inner bottom of the liquid accumulation cup 1 to concentrate at the drainage port, avoiding excessive accumulation of condensed water inside the liquid accumulation cup 1 before the drainage port is opened.
[0039] See Figure 1 , the device provided in this embodiment further includes a drainage bag 7, and the inlet of the drainage bag 7 is connected to the drainage pipe 3. The drainage bag 7 is used to collect the condensed water flowing out of the drainage pipe 3 every day and is emptied once a day.
[0040] A drain pipe 8 is provided at the bottom end of the drainage bag 7, and a valve 9 is provided on the drain pipe 8. By opening the valve 9, the condensed water collected in the drainage bag 7 can be directly discharged through the drain pipe 8.
[0041] Optionally, the valve 9 is a plug valve. See Figure 4 , pushing the plug to the left closes the valve; pulling the plug to the right opens the valve.
[0042] In order to record the daily drainage volume, in this embodiment, the drainage bag 7 is a transparent bag, and a scale is provided on the drainage bag 7. By observing the volume of the condensed water in the drainage bag 7, the daily drainage volume can be recorded to indirectly evaluate the humidification effect.
[0043] As needed, an exhaust hole 14 is provided on the drainage bag 7. The exhaust hole 14 exhausts gas but does not drain liquid. When the gas in the breathing pipeline accidentally enters the drainage bag 7, the gas can be discharged through this exhaust hole 14 to prevent the drainage bag 7 from being affected in use due to being filled with gas.
[0044] As needed, a handle 15 is provided on the drainage bag 7. It is convenient to hang the drainage bag 7 or manually carry the drainage bag 7.
[0045] See Figure 3 , in this embodiment, an anti-backflow mechanism is provided inside the drainage pipe 3. It is used to prevent the condensed water from flowing back into the liquid accumulation cup 1 and even causing infection.
[0046] Specifically, the anti-backflow mechanism may include a fluid guide 10, a support member 11, a plugging body 12, and an elastic member 13.
[0047] Both the fluid guide 10 and the support member 11 are arranged in the drainage tube 3. The support member 11 is located below the fluid guide 10. The outer side wall of the fluid guide 10 is hermetically connected to the inner side wall of the drainage tube 3, and a fluid guiding channel for the fluid to pass through is provided in the fluid guide 10. The plugging body 12 is located between the fluid guide 10 and the support member 11. Both ends of the elastic member 13 are respectively connected to the support member 11 and the plugging body 12. The elastic member 13 is used to support the plugging body 12 so that the plugging body 12 blocks the bottom end of the fluid guiding channel.
[0048] When there is condensed water flowing downward in the drainage tube 3, due to the gravitational force of the condensed water, the plugging body 12 is pressed downward. At this time, a gap appears between the plugging body 12 and the fluid guide 10, and the condensed water flows down smoothly. When there is no water flow in the drainage tube 3, due to the supporting effect of the elastic member 13, the plugging body 12 blocks the bottom end of the fluid guiding channel, and the condensed water cannot flow back into the liquid accumulation cup 1.
[0049] Optionally, the elastic member 13 is a spring.
[0050] The plugging body 12 is a spherical structure, and a chamfer structure adapted to the spherical structure is formed at the bottom end of the fluid guiding channel of the fluid guide 10, which can improve the sealing performance when the plugging body 12 blocks the bottom end of the fluid guiding channel.
[0051] In the present utility model, the mechanisms, components, and parts for which no specific structures are described are existing structures that already exist in the prior art and can be directly purchased on the market.

Therefore, it should not be construed as a limitation to the present utility model.
