Description

Technical Field

[0001] The utility model relates to a condensate water collection device for a ventilator, belonging to the technical field of medical devices. Background Art

[0002] During the process of a patient using a ventilator, due to the temperature difference between the inside and outside of the pipeline, condensate water often appears on the inner wall of the pipeline; condensate water is an important cause of ventilator-associated pneumonia, and the harms to the patient include: generating flow velocity in the loop, increasing the risk of man-machine confrontation; directly pouring back into the patient's airway when the air flow is too large, resulting in patient asphyxia; too much condensate water will increase the occurrence of ventilator-associated pneumonia, etc.

[0003] Therefore, in addition to the basic air pipeline on the ventilator pipeline, it also includes a Y-shaped pipe assembly and a water collecting cup assembly. Its capacity is usually designed to be small, so medical staff need to remove the water collecting cup assembly before it is full, pour out the water inside, and then reconnect the Y-shaped pipe assembly for use, or replace it with a new water collecting cup assembly and connect it to the Y-shaped pipe assembly for use. The replacement frequency is usually 2 hours / time. In the prior art, a self-sealing structure is adopted for the Y-shaped pipe assembly, so that when the water collecting cup assembly is removed, the lower end of the Y-shaped pipe assembly is automatically closed, preventing bacteria in the external environment from entering the air pipeline through the Y-shaped pipe assembly and being inhaled by the patient, which may cause the patient's infection to worsen; it also avoids the medical staff replacing the water cup being infected by the germs contained in the patient's exhaled gas (for example, patients in the ICU usually have serious conditions, and their exhaled gas also contains a large amount of germs). However, this method has problems: when replacing the water collecting cup, the upper part of the cup body is in an open state. If not sealed, the condensate water inside also carries a large amount of germs, and the splashing or volatilization of the condensate water will cause medical staff to be exposed to a working environment with high-risk germs, resulting in a great risk of cross-infection between medical staff and patients. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a condensate water collection device for a ventilator, which can discharge the condensate water without opening the cover.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A condensate water collection device for a ventilator includes a water collecting cup. The water collecting cup includes a cup body. A Y-shaped tee is provided at the upper part of the cup body, and the bottom of the Y-shaped tee is communicated with the inside of the cup body; a liquid discharge pipe is provided at the lower end of the cup body; a liftable plugging member is provided inside the cup body, and the lower part of the plugging member corresponds to the liquid discharge pipe.

[0009] Alternatively, a cup cover is provided above the water collecting cup. The Y-shaped tee joint is arranged on the cup cover, and a pressing valve is arranged at the bottom of the Y-shaped tee joint; when the cup cover is assembled on the cup body, the guiding cylinder acts on the pressing valve.

[0010] Alternatively, a warning line is provided on the water collecting cup.

Detailed Embodiments

[0021] The present utility model will be described in detail below with reference to the drawings.

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] A condensate collection device for a ventilator, as Figure 1 shown, includes a water accumulation cup 1. The water accumulation cup 1 includes a cup body 11. A Y-shaped three-way pipe 2 is provided at the upper part of the cup body 11. The bottom of the Y-shaped three-way pipe 2 is communicated with the inside of the cup body 11, and a pressing valve 6 is provided at the bottom of the Y-shaped three-way pipe 2. A drain pipe 3 is provided at the lower end of the cup body 11. A liftable plugging member 4 is provided in the cup body 11, and the lower part of the plugging member 4 corresponds to the drain pipe 3.

[0024] In this way, both the cup body 11 of the water accumulation cup 1 and the Y-shaped three-way pipe 2 can adopt existing structures. Among them, the upper two ends of the Y-shaped three-way pipe 2 are connected to the air pipeline, and the bottom end is connected to the water accumulation cup 1 for receiving the water liquefied from the hot and humid gas during the patient's breathing. Specifically, when the plugging member 4 is in the lower position, the drain pipe 3 is plugged, so that the inside of the water accumulation cup 1 is not communicated with the outside, and water passing and air passing cannot be realized. The condensate flows into the water accumulation cup 1 from the bottom of the Y-shaped three-way pipe 2, and the water accumulation cup 1 can store water. When the plugging member 4 is moved upward, the drain pipe 3 is in an open state, and the condensate flows out from the drain pipe 3. After the condensate has flowed out, the drain pipe 3 is plugged again. Even if the lower part of the drain pipe 3 is plugged and there is temporarily stored water in the water accumulation cup 1, the inside and outside air can be isolated by the condensate. Furthermore, the inside and outside air of the water accumulation cup 1 is isolated, ensuring that the gas inhaled by the patient comes from the ventilator, avoiding the contamination of the pipeline by microorganisms in the air and entering the patient's respiratory tract during the treatment process, increasing the risk of infection. At the same time, it is ensured that only condensate is discharged without gas, avoiding the discharge of germs contained in the patient's exhaled gas.

[0025] As another specific embodiment, the plugging member 4 is a float. By setting the float, when there is more condensate in the water accumulation cup 1, the float can be automatically lifted by the buoyancy force to discharge the condensate from the water accumulation cup 1, and the drain pipe 3 is automatically closed after the discharge. Further, the lower end of the float is conical or arc-shaped, which can ensure the degree of fit with the drain pipe 3.

[0026] As another specific embodiment, a guiding cylinder 5 is provided in the cup body 11. The lower part of the guiding cylinder 5 corresponds to the drain pipe 3. A communication hole 51 communicating the inside and outside of the guiding cylinder 5 is provided on the guiding cylinder 5, and the float is arranged in the guiding cylinder 5. The guiding cylinder 5 can guide the position of the float to ensure that when the water level drops, the float can fall to the drain pipe 3 and plug the drain pipe 3. Further, in order to prevent the guiding cylinder 5 from causing water accumulation and plugging at the drain pipe 3, an inclined support frame is provided at the lower end of the guiding cylinder 5.

[0027] As another specific embodiment, a cup cover 12 is provided above the water accumulation cup 1, the Y-shaped three-way joint 2 is arranged on the cup cover 12, and a pressing valve 6 is arranged at the bottom of the Y-shaped three-way joint 2; when the cup cover 12 is assembled on the cup body 11, the guiding cylinder 5 acts on the pressing valve 6. In this solution, when the assembly is completed, the guiding cylinder 5 acts on the pressing valve 6 so that the pressing valve 6 can flow smoothly; when the cup cover 12 is opened, the guiding cylinder 5 stops acting on the pressing valve 6 continuously, and the pressing valve 6 closes to block the flow of the Y-shaped three-way joint 2. Compared with the previous solution, this solution adds a backup method of manual opening when the float flow is abnormal.

[0028] As another specific embodiment, a warning line 7 is provided on the water accumulation cup 1. Since in the previous embodiment, when the float flow is abnormal, it is necessary to open it manually. The warning line 7 in this way can judge whether it is in an abnormal situation. Further, the boundary line can be a concave-convex scale line or a colored identification line.

[0029] As another specific embodiment, the bottom of the cup body 11 is a cone with the tip facing downwards, and the drain pipe 3 is arranged at the tip of the cone. When draining water, the inclined bottom can help drain the water in the cup body 11 completely, reduce residues, and avoid water accumulation and bacteria breeding.

[0030] As another specific embodiment, a drainage bag 8 is provided downstream of the drain pipe 3. The drainage bag 8 can collect the condensed water, reducing the chance of direct contact with the external environment, thereby reducing the risk of infection.

[0031] As another specific embodiment, a positive pressure switch 9 is provided below the drainage bag 8. The positive pressure switch 9 ensures that the liquid in the drainage bag 8 can only flow out unidirectionally, which helps to maintain the stability and continuity of the drainage system and prevent external bacteria or pollutants from flowing back. When it is necessary to empty the drainage bag 8, the drainage speed can be easily controlled through the positive pressure switch 9 to avoid splashing caused by too fast liquid emptying.

[0032] As another specific embodiment, a safety switch 10 is further provided between the water accumulation cup 1 and the drainage bag 8. The safety switch 10 can control the connection between the water accumulation cup 1 and the drainage bag 8.

[0033] As another specific embodiment, the safety switch 10 is a stop clamp or a regulating valve. The stop clamp and the regulating valve are common medical devices for controlling the flow. Adopting one of these devices is more convenient and low-cost, and at the same time, medical staff are familiar with the operation.
