Description

Technical Field

[0001] The utility model relates to the field of ventilator auxiliary devices, in particular to a condensate water collection and treatment device for a ventilator pipeline. Background Art

[0002] A ventilator is an indispensable device in the modern medical system. During clinical medical assistance, ventilators are often used to assist patients in breathing or even replace patients in breathing. When a ventilator is in use, condensate water will be generated in the breathing pipeline.

[0003] The condensate water accumulated in the pipeline not only affects the delivery of oxygen, but also contains a large number of germs. If the condensate water accumulated in the pipeline flows back into the patient's airway, it is extremely likely to cause ventilator-associated diseases. Therefore, a water collecting cup is usually set on the ventilator pipeline to collect the condensate water in the pipeline, and the condensate water in the water collecting cup is processed in a timely manner.

[0004] In the treatment of the condensate water in the water collecting cup, generally, medical staff need to separate the water collecting cup from the ventilator pipeline. First, pour the condensate water in the cup into a disinfection bucket for disinfection, and then it can be discharged into the sewer.

[0005] During the process of separating the water collecting cup and pouring the condensate water, insufficient ventilation or even asphyxia may occur due to the leakage of gas in the ventilator pipeline; secondly, affected by the impact of the exhaled gas flow during the pouring process, aerosol will be dispersed in the air, and since the water collecting cup needs to be separated from the pipeline, the condensate water in the pipeline may drip, affecting medical staff or the surrounding environment. Content of the Utility Model

[0006] The utility model provides a condensate water collection and treatment device for a ventilator pipeline, and the technical problem to be solved is that there is no need to separate the water collecting cup from the ventilator pipeline, and the condensate water in the water collecting cup can be disinfected to avoid the impact on patients, medical staff and the surrounding environment during the separation process of the water collecting cup.

[0020] As Figures 1-3 shown, a condensate water collection and treatment device for a ventilator pipeline in the present application includes a water accumulation cup 1, a liquid collection bag 2 and a diversion tube 3. The device is connected to the ventilator pipeline through a connecting end 11 provided on the water accumulation cup 1, so that the condensate water in the ventilator pipeline can be filtered out and gathered in the water accumulation cup 1. When collecting the condensate water in the water accumulation cup 1, it is not necessary to separate the water accumulation cup 1 from the pipeline. The condensate water in the water accumulation cup 1 can be hermetically diverted and collected in the liquid collection bag 2 through the diversion tube 3, and the liquid collection bag 2 can be disassembled and replaced. A switch valve 31 provided on the diversion tube 3 can disconnect the diversion tube 3 to prevent the condensate water in the water accumulation cup 1 from forming an aerosol or dripping, which may affect patients and medical staff. At the same time, a disinfection tablet 21 is provided in the liquid collection bag 2, which can disinfect and kill the condensate water in the liquid collection bag 2.

[0021] Reference Figure 1, a connection end 11 for connecting with a ventilator pipeline is provided at the upper end of the water accumulation cup 1. The connection end 11 includes an air inlet interface 111 connected to the ventilator inlet pipe and an air outlet interface 112 connected to the ventilator outlet pipe. Both the air inlet interface 111 and the air outlet interface 112 are fixedly connected to the water accumulation cup 1 at one end and detachably connected to the ventilator pipeline at the other end. The air inlet interface 111 and the air outlet interface 112 are respectively connected to the lowest ends of the inlet pipe and the outlet pipe on the ventilator, so as to filter the condensed water in the ventilator pipeline into the water accumulation cup 1.

[0022] Further, check valves 113 that can only flow downward are provided in both the air inlet interface 111 and the air outlet interface 112. By providing check valves 113 that can only flow downward in the air inlet interface 111 and the air outlet interface 112, the condensed water in the water accumulation cup 1 can be prevented from flowing backward, causing ventilator-related diseases to the patient.

[0023] Reference Figure 1 and Figure 2 , the liquid collection bag 2 is a transparent and soft film bag, and the inside of the bag is in a vacuum state. A scale line 24 is provided on the liquid collection bag 2. During the process of collecting condensed water, there is no need to discharge air, preventing the germs in the condensed water from causing pollution through aerosols. And through the scale line 24 provided on the liquid collection bag 2, the collection amount of condensed water in the liquid collection bag 2 can be observed.

[0024] The liquid collection bag 2 is located below the water accumulation cup 1 and is detachably connected to the water accumulation cup 1 through a diversion pipe 3. A disinfection tablet 21 is provided inside the liquid collection bag 2. Thus, the condensed water in the water accumulation cup 1 can be hermetically collected in the liquid collection bag 2 through the diversion pipe 3, and the liquid collection bag 2 can be disassembled and replaced. During the process of replacing the liquid collection bag 2, the ventilator does not need to be shut down, nor will the gas in the ventilator pipeline leak, making it more convenient to use.

[0025] And a disinfection tablet 21 is provided inside the liquid collection bag 2, which can disinfect the condensed water in the liquid collection bag 2, thereby timely disinfecting the germs in the condensed water and avoiding pollution caused by the leakage of condensed water. Specifically, the disinfection tablet 21 in this embodiment can be a chlorine-containing effervescent tablet, and this disinfection tablet 21 can dissolve in the condensed water to disinfect the condensed water.

[0026] A hanging rope 23 is provided at the upper end of the liquid collection bag 2. The liquid collection bag 2 can be hung on the ventilator or a more conspicuous place on the hospital bed through the hanging rope 23, facilitating timely observation of the collection amount of condensed water in the liquid collection bag 2 and facilitating timely replacement of the liquid collection bag 2.

[0027] Furthermore, in order to reduce the usage amount of the liquid collection bag 2 and lower the usage cost, a plurality of disinfection tablets 21 can be arranged in the liquid collection bag 2, and a plastic film filled with gas is used to separate and protect the plurality of disinfection tablets 21. A liquid discharge switch 22 is arranged at the lower end of the liquid collection bag 2. By squeezing and breaking the plastic film separating the disinfection tablets 21, the condensed liquid can contact the disinfection tablets 21, and then dissolve in the condensed liquid to disinfect and kill the condensed liquid. After the liquid collection bag 2 is filled and disinfected by the disinfection tablets 21, the disinfected condensed water in the liquid collection bag 2 can be discharged into the sewer through the liquid discharge switch 22. Then, by squeezing a new disinfection tablet 21, the liquid collection bag 2 can be reused until all the disinfection tablets 21 are consumed.

[0028] Reference Figure 2 , specifically, the liquid discharge switch 22 includes a liquid discharge pipe 221 and a piston 222. The liquid discharge pipe 221 is fixedly connected to the liquid collection bag 2 and is communicated with the inside of the liquid collection bag 2. The piston 222 is slidably arranged on the liquid discharge pipe 221, and one end extends out of the liquid discharge pipe 221 and can close and open the liquid discharge pipe 221. One end of the piston 222 extends out of the outside of the liquid discharge pipe 221. By pressing one end of the piston 222 extending out of the liquid discharge pipe 221, the piston 222 can slide, thereby being used to close the liquid discharge pipe 221 for collecting condensed water, or to conduct the liquid discharge pipe 221 to discharge the disinfected condensed water into the sewer.

[0029] Optionally, the suspended end of the liquid discharge pipe 221 is a slope. The suspended end of the liquid discharge pipe 221 is provided with a slope, which can reduce the occurrence of the condensed water remaining in the liquid discharge pipe 221 when discharging the disinfected condensed water into the sewer.

[0030] Reference Figure 1 , the diversion pipe 3 is used to connect the water accumulation cup 1 and the liquid collection bag 2, and the condensed water in the water accumulation cup 1 is hermetically diverted and collected in the liquid collection bag 2 through the diversion pipe 3, avoiding the need to separate the water accumulation cup 1 from the ventilator pipeline when collecting the condensed water in the water accumulation cup 1 and preventing the condensed water containing a large amount of germs from causing pollution; wherein, the upper end of the diversion pipe 3 is fixedly connected to the water accumulation cup 1, and the lower end is detachably connected to the liquid collection bag 2 through a connector 4.

[0031] Furthermore, a switch valve 31 is also arranged on the diversion pipe 3. The switch valve 31 is located between the water accumulation cup 1 and the liquid collection bag 2. During the process of disassembling the liquid collection bag 2, the switch valve 31 arranged on the diversion pipe 3 can be closed to avoid the condensed liquid in the water accumulation cup 1 flowing down and dripping into the environment during the disassembly of the liquid collection bag 2, causing pollution.

[0032] Reference Figure 1 and Figure 3, the liquid collection bag 2 is detachably connected to the diversion tube 3 through a connector. Among them, the connector 4 includes a male connector 41 and a female connector 42. The male connector 41 is fixedly connected to the diversion tube 3, and the female connector 42 is fixedly connected to the liquid collection bag 2. The male connector 41 can be inserted into the female connector 42 and is detachably connected to the female connector 42 through threads; moreover, self-sealing components are provided inside both the male connector 41 and the female connector 42. Through the elastic self-sealing components, when the male connector 41 and the female connector 42 are separated, the male connector 41 and the female connector 42 can be automatically sealed to prevent a small amount of condensate remaining in the diversion tube 3 and the condensate in the liquid collection bag 2 from overflowing and polluting the environment.

[0033] Reference Figure 3 , specifically, a sealing ball 411 and a first spring 412 are provided inside the male connector 41. Under the action of the first spring 412, the sealing ball 411 can seal the male connector 41. A sealing gasket 421 and a second spring 422 are provided inside the female connector 42. Under the action of the second spring 422, the sealing gasket 421 can seal the female connector 42. A support column 423 is fixedly provided at the upper end of the sealing gasket 421. As the male connector 41 is inserted into the female connector 42, the support column 423 can abut against the sealing ball 411 and push the sealing ball 411 and the sealing gasket 421 open.

[0034] During use, the device is connected to the ventilator pipeline through the connection end 11 on the water collecting cup 1, and the ventilator is started. At this time, the condensate in the ventilator pipeline can be filtered into the water collecting cup 1, and the condensate in the water collecting cup 1 will be diverted and collected into the liquid collection bag 2 suspended below the water collecting cup 1 through the diversion tube 3. A disinfection tablet 21 is provided inside the liquid collection bag 2, which can disinfect and kill the condensate in the liquid collection bag; when the liquid collection bag is full, the on-off valve 31 on the diversion tube 3 can be closed, and wait for a period of time so that the disinfection tablet 21 can fully disinfect and kill the condensate in the liquid collection bag. At this time, since the water collecting cup 1 can still temporarily store the condensate, the ventilator does not need to be shut down and can be used normally.

[0035] After the condensate in the liquid collection bag 2 has been fully disinfected and killed, the liquid collection bag 2 can be detached, and the fully disinfected and killed condensate in the liquid collection bag 2 can be discharged into the sewer through the liquid discharge switch 22, or directly into a bucket. After squeezing a new disinfection tablet 21, the old liquid collection bag 2 can be reused. Open the on-off valve 31 to continue collecting and disinfecting the condensate in the water collecting cup 1. After all the disinfection tablets 21 are consumed, the liquid collection bag 2 can be detached and replaced with a new one.

[0036] When the above-mentioned collection and treatment device is in use, it can avoid disassembling the water accumulation cup 1, thereby preventing the leakage of gas in the ventilator pipeline, which may lead to insufficient ventilation or even asphyxia of the patient. Secondly, during the process of disassembly and pouring, affected by the impact of the exhaled gas flow, aerosol may be dispersed in the air, and since the water accumulation cup 1 needs to be separated from the pipeline, the condensed water in the pipeline may drip, which may affect medical staff or the surrounding environment. This device can collect the condensed water of the water accumulation cup 1 into the liquid collection bag 2 through the closed diversion pipe 3, and a disinfection tablet 21 is arranged in the liquid collection bag 2, which can only disinfect the condensed water, effectively preventing pollution. Moreover, the liquid collection bag 2 can be reused multiple times, reducing the use cost. When disassembling the liquid collection bag 2, through the on-off valve 31 arranged on the diversion pipe 3 and the elastic self-sealing component arranged in the joint, it can effectively prevent the condensed liquid from overflowing or dripping and polluting the environment.

[0037] It should be understood that all the above embodiments are exemplary rather than restrictive. Under the concept of the present invention, various modifications or deformations made by those skilled in the art to the specific embodiments described above should be within the protection scope of the present invention.
