Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a closed-type condensate water treatment device for a ventilator. Background Technique

[0002] Ventilators are commonly used in clinical practice for the prevention and treatment of respiratory failure. A heating and humidifying system is usually provided inside the ventilator to process the gas, making the temperature inside the ventilator higher than the room temperature. The humid gas is extremely easy to condense and accumulate on the inner wall of the pipeline. Such a humid environment is prone to bacterial colonization, and there is a risk of condensate water flowing back into the humidification tank and the patient's airway. Moreover, a large amount of condensate water remains on the inner wall of the ventilator pipeline, which is likely to cause the lumen to narrow and increase the resistance of the gas flow. Currently, most ventilators on the market are generally equipped with a water collection cup to collect and treat the condensate water, and the condensate water in the water collection cup needs to be poured manually. However, since the water collection cup needs to be unscrewed manually during the pouring process, this process causes the opening of the ventilator pipeline, affects the normal air supply of the ventilator, and is not conducive to the recovery of the patient's respiratory function. At the same time, the condensate water is extremely easy to splash onto the operator's hands, body parts and the surrounding environment of the bed during the pouring process, seriously increasing the risk of cross-infection, not being conducive to the recovery of the patient, and increasing the occupational exposure risk of medical staff.

[0003] Therefore, it is necessary to design a closed-type condensate water treatment device for a ventilator that can effectively overcome the above problems. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a closed-type condensate water treatment device for a ventilator, which can collect and discharge the condensate water appearing in the ventilator pipeline in a fully closed manner, without unscrewing or disassembling the water collection cup for pouring, ensuring that the ventilator pipeline is always in a closed state during the condensate water collection process and the condensate water discharge process, and reducing the risk of infection.

At this time, the liquid inlet hole is closed, and the pipeline between the ventilator pipeline and the Y-shaped connecting pipe is closed, and there is no need to unscrew the water accumulation cup, thus avoiding the infection risk caused by the opening of the pipeline and ensuring the safety of doctors and patients.

Among them, the connecting end cover 1 is provided with a Y - shaped connecting pipe 11, and it is connected to the pipeline of the ventilator through the Y - shaped connecting pipe 11.

[0038] Referring to Figure 2 shown, a check valve 12 is arranged inside the connecting end cover 1, and the check valve 12 is a valve - type check valve 12, so that the condensate water can only flow unidirectionally from the Y - shaped connecting pipe 11 into the lower water accumulation cup 2.

[0040] Optionally, in some embodiments, the connecting end cover 1 and the water accumulation cup 2 are integrally connected, so that the inner cavity of the connecting end cover 1 and the inner cavity of the water accumulation cup 2 form a closed liquid - collecting space.

[0041] As shown Figure 4 in the figure, inside the water accumulation cup 2, there are a liquid inlet plate 21 located above, a liquid discharge plate 22 located below, and a valve lock assembly 3 located between the liquid inlet plate 21 and the liquid discharge plate 22. The liquid inlet plate 21 is provided with a liquid inlet hole 211 penetrating through its plate body. The liquid discharge plate 22 is provided with a liquid discharge hole 221 penetrating through its plate body.

Refer to Figure 5 As shown, the upper valve disc 31 and the inner cavity of the water accumulation cup 2 below it are in a liquid discharge state communicating with the drain port 23; or when the liquid discharge plug 321 is in a state of being directly opposite and blocking the liquid discharge hole 221, the liquid inlet hole 211 is directly opposite the liquid inlet port 312, and the lower valve disc 32 and the inner cavity of the water accumulation cup 2 above it are in a liquid collection state communicating with the connecting end cover 1 and the ventilator pipeline, and the condensed water is collected and converged above the lower valve disc 32 of the water accumulation cup 2.

[0044] The upper valve disc 31 is located below the liquid inlet plate 21 and the liquid inlet plug 311 is arranged on the upper end face of the upper valve disc 31, and the lower valve disc 32 is located above the liquid discharge plate 22 and the liquid discharge plug 321 is arranged on the lower end face of the lower valve disc 32.

[0045] Combined with Figure 3 、 Figure 5 As shown, the upper valve disc 31 and the lower valve disc 32 are both provided with a sealing ring edge 34 located on the outer edge of their circumferences. Refer to Figure 4 As shown, the side wall of the water accumulation cup 2 is provided with a sealing ring groove 24, the sealing ring edge 34 is movably embedded in the sealing ring groove 24, and the outer side wall of the water accumulation cup 2 is provided with a receiving arc groove 25 communicating with the sealing ring groove 24.

[0046] As Figure 3 shown, the valve locking rod 33 includes a linkage rod 331 parallel to the axis of the water accumulation cup 2, and an upper valve block 332 and a lower valve block 333 arranged at both ends of the linkage rod 331. The upper valve block 332 and the lower valve block 333 are both movably embedded in the receiving arc groove 25, and are respectively fixedly connected to the upper valve disc 31 and the lower valve disc 32. During use, only by pushing the linkage rod 331 to drive the upper valve disc 31 and the lower valve disc 32 to rotate left or right synchronously can the liquid collection state or the liquid discharge state of the overall condensed water treatment device be changed.
