Description

Technical Field

[0001] The invention relates to the field of water collecting cups for ventilators, and in particular to a condensed water zero-contact water collecting cup for ventilators. Background Art

[0002] Because the gas exhaled by the ventilator is dry, humidification plays a vital role in preventing hypothermia, damage to respiratory epithelial tissue, bronchospasm, atelectasis and airway obstruction. In some cases, excessive viscosity of airway secretions can lead to obstruction of the endotracheal tube. Therefore, it is particularly important to heat and humidify the gas exhaled by the ventilator. The heated and humidified gas is delivered to the patient through the breathing tube. The breathing tube is usually long and usually does not have a heat preservation and heating device. Therefore, the heated and humidified gas will produce condensed water when passing through the breathing tube.

[0003] Condensate in the ventilator circuit that contains high concentrations of pathogens and VAP risk factors must be removed regularly and treated as infectious waste. It is strictly forbidden to dump it at will. Studies have shown that the positive rate of bacterial culture of condensate is as high as 86.7%. Therefore, when disconnecting the ventilator or handling condensate, it should be avoided that the condensate is accidentally splashed and contaminated by nursing staff, backflow into the patient's airway, and contaminated the surrounding environment.

[0004] However, the existing water collection cups are often inconvenient to install and remove, and are not easy to remove if they are installed too tightly; if they are installed too loosely, they are easy to fall off, causing the condensed water in the cup to splash accidentally, causing pollution to the ground and surrounding air; in the process of medical staff pouring out the condensed water in the water collection cup, it is easy to contaminate the hands of the medical staff, which is inconvenient to operate and easily causes environmental pollution, especially for water collection cups used for infectious diseases.

[0005] Therefore, it is necessary to invent a closed condensation water zero-contact water collection cup for a ventilator to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a closed condensation water zero-contact water collecting cup for a ventilator to solve the problems raised in the above background technology.

[0010] Preferably, an inflatable airbag is provided at the bottom of the water collecting cup body, and an air inlet tube connected to the interior of the funnel airbag is provided at the end of the inflatable airbag.

[0011] By reciprocatingly squeezing the inflatable airbag, the gas in the inflatable airbag can be transferred back and forth between the funnel airbag and the inflatable airbag, so that the funnel airbag is in a state of inflation and inhalation vibration, while the inflatable airbag is closed and no new gas is added, which will not cause the funnel airbag to over-expand.

[0015] When the movable core moves toward the discharge pipe, the pushing effect of the gas causes the one-way plugging plate to move toward the side away from the limit single-opening plate, so that the external gas flows into the discharge pipe from the inner circle of the limit single-opening plate, the outer circle of the one-way plugging plate, and the piston cylinder in sequence, and discharges the liquid in the discharge pipe, which helps the liquid to be discharged and prevents the sputum in the liquid from blocking the pipe.

A funnel-shaped funnel air bag 12 is provided inside the water collecting cup body 1, and a heat conducting plate 13 is provided on the upper surface of the middle position of the funnel air bag 12. The lower surface of the heat conducting plate 13 is located inside the funnel air bag 12 and is fixedly fitted with a heating unit 14. The upper end of the discharge pipe 6 is connected to an upper limit plate 11 through a threaded fit. The upper limit plate 11 is arranged inside the water collecting cup body 1, and a leakage hole 10 is provided on the side of the discharge pipe 6 below the upper limit plate 11.

[0033] In this embodiment, a support bottom plate 8 is fixedly provided at the bottom of the funnel airbag 12, and a plurality of support springs 9 are fixedly provided on the lower surface of the support bottom plate 8, and the support springs 9 are fixed to the inner bottom surface of the water collection cup body 1;

[0034] It should be noted that the support spring 9 supports the support bottom plate 8 and the funnel airbag 12, so that the funnel airbag 12 has an enhanced vibration effect during inflation and inhalation vibration, making it easy to discharge sputum in the condensed water in the water collection cup body 1.

[0035] Furthermore, an inflatable airbag 16 is provided at the bottom of the water collecting cup body 1 , and an air inlet capillary 15 communicating with the interior of the funnel airbag 12 is provided at the end of the inflatable airbag 16 .

[0036] By reciprocatingly squeezing the inflatable airbag 16, the gas in the inflatable airbag 16 can be transferred back and forth between the funnel airbag 12 and the inflatable airbag 16, so that the funnel airbag 12 is in a state of inflation and inhalation vibration, while the inflatable airbag 16 is closed and no new gas is added, which will not cause the funnel airbag 12 to over-expand.

[0037] Specifically, one side of the discharge pipe 6 is connected to a piston cylinder 17, which is arranged above the manual switch valve 7. A piston core 19 is provided in the piston cylinder 17, and a piston rod 18 extending to the outside of the piston cylinder 17 is fixedly provided on one side of the piston core 19. The piston cylinder 17 is arranged perpendicular to the side of the discharge pipe 6.

[0038] When the movable rod 18 pushes the piston core 19 to move in the piston cylinder 17, the discharge pipe 6 can be inflated, so that the sputum contained in the condensed water inside the water collection cup body 1 is easily discharged.

[0039] In this embodiment, a limiting single-open plate 22 is arranged inside the piston cylinder 17 on the side of the piston core 19 close to the discharge pipe 6. The limiting single-open plate 22 is fixedly arranged on the inner wall of the piston cylinder 17. A built-in groove 20 is arranged on the side of the limiting single-open plate 22 close to the discharge pipe 6. A tensioning spring 23 is fixedly arranged in the built-in groove 20. A one-way blocking plate 24 is fixedly arranged at the end of the tensioning spring 23. The one-way blocking plate 24 corresponds to one side of the limiting single-open plate 22. The diameter of the one-way blocking plate 24 is larger than the inner diameter of the limiting single-open plate 22 and smaller than the inner diameter of the piston cylinder 17.

[0040] When the movable core 19 moves toward the side of the discharge pipe 6, the pushing effect of the gas causes the one-way plugging plate 24 to move toward the side away from the limit single-open plate 22, so that the external gas flows into the discharge pipe 6 from the inner circle of the limit single-open plate 22, the outer circle of the one-way plugging plate 24, and the piston cylinder 17 in a one-way manner, and the liquid in the discharge pipe 6 is discharged, which assists in the discharge of condensed water and prevents the phlegm in the condensed water from blocking the pipe. The one-way valve above the discharge pipe 6 prevents the gas pushed into the discharge pipe 6 from being discharged upward.

[0041] It should be noted that a supplementary pipe 21 is provided on one side of the piston cylinder 17 and is connected to the interior of the piston cylinder 17 . The supplementary pipe 21 is arranged between the limiting single-open plate 22 and the piston core 19 .

[0042] The one-way valve in the supplementary pipe 21 ensures that gas can enter the exhaust pipe 6 from the outside in one direction.

[0043] Both the replenishing pipe 21 and the discharge pipe 6 are provided with a one-way valve. The one-way valve in the discharge pipe 6 allows the fluid inside the water collecting cup body 1 to flow into the discharge pipe 6 in one direction, and the one-way valve in the replenishing pipe 21 allows the external gas to flow into the piston cylinder 17 in one direction through the replenishing pipe 21.

[0044] The support base plate 8 is a round rod-shaped structure. One end of the support base plate 8 away from the piston core 19 is integrally provided with a large round handle with a diameter larger than that of the support base plate 8 . The diameter of the support base plate 8 is smaller than the inner diameter of the piston cylinder 17 .

[0045] The air inlet and outlet pipes 4 are connected to the interior of the water collecting cup body 1 , and the air inlet pipe 3 and the air outlet pipe 5 are connected to the air inlet and outlet pipe 4 , and the air inlet and outlet pipe 4 is arranged above the discharge pipe 6 .

[0046] Working principle: It comprises a water collecting cup body 1, and a water collecting cup cover body 2 connected by threaded fitting is arranged above the water collecting cup body 1.

[0047] The inner wall of the water collecting cup cover 2 has an internal thread. The upper end of the water collecting cup body 1 has an external thread that matches the internal thread of the cover 2. Both the water collecting cup cover 2 and the water collecting cup body 1 can be made of transparent materials. There is a screw-in degree mark on the water collecting cup cover 2. The screw-in mark can be a marking line or a marking protrusion, or even a marking pattern, etc. There can be multiple screw-in degree marks on the water collecting cup cover 2, and the water collecting cup can be switched to different states by screwing the upper end of the water collecting cup body 1 into the cover 2 to different degrees.

[0048] For example, the water collecting cup cover 2 has two marking lines, wherein one marking line (the first marking line) is screwed in deeper than the other marking line (the second marking line), that is, the first marking line is located deeper or more inside the cover 2 than the second marking line. When the upper end of the water collecting cup body 1 is screwed into the water collecting cup cover 2 to the second marking line, the support spring 9 is compressed to a certain amount, and the ventilator can be in normal operation. The gas in the pipeline enters the water collecting cup to gradually generate condensed water, but the inflow amount is not at the maximum condensed water inflow amount, but the ventilator is in the best air delivery state. When the condensed water needs to be dumped, the water collection cup body 1 can be screwed into the first marking line of the cover body 2, and the support spring 9 can be compressed to the shortest state. At this time, the amount of condensed water flowing into the water collection cup is at the maximum flow state. Correspondingly, the air supply state is not the best state at this time. After collecting the desired amount of condensed water and entering the plastic storage bag 25, the water collection cup body 1 is rotated back to the second marking line under the indication of the screw-in degree mark, and the pipeline is adjusted to the best air supply state of the ventilator. This is not only convenient for medical staff to operate, but also very good for patients using it, and has a very high application value.

[0049] An air inlet and outlet pipe 4 is provided in the middle position of the upper end of the water collecting cup cover 2, one end of the air inlet and outlet pipe 4 is provided with an air inlet pipe 3, and the other end is provided with an air outlet pipe 5, the lower end of the water collecting cup body 1 is provided with a discharge pipe 6 connected by threaded cooperation, and the lower end position of the discharge pipe 6 is provided with a manual switch valve 7, and the lower end of the discharge pipe 6 is sleeved with a plastic storage bag 25, and the lower end of the plastic storage bag 25 is fixedly provided with a bottom sealing plate 26, and the middle position of the bottom sealing plate 26 is provided with an outlet hole 27 connected to the inside of the plastic storage bag 25, and an elastic band 29 is fixedly provided at the outer circle of the lower end of the plastic storage bag 25, and a sealing plug 28 matching the outlet hole 27 is fixedly provided on the elastic band 29, the condensed water in the water collecting cup body 1 can flow into the plastic storage bag 25, and then the outlet hole 27 is opened for excretion, which will not cause pollution to the hands of medical staff and the surrounding environment, and reduce the risk of leakage when dumping the collected condensed water, especially for respiratory discharge of patients with communicable diseases, which has great practical value.

[0050] A funnel-shaped funnel airbag 12 is provided inside the water collecting cup body 1, and a heat conducting plate 13 is provided on the upper surface of the middle position of the funnel airbag 12. The lower surface of the heat conducting plate 13 is located inside the funnel airbag 12 and fixedly fitted with a heating unit 14. The upper end of the discharge pipe 6 is connected with an upper limit plate 11 through a threaded fit. The upper limit plate 11 is arranged inside the water collecting cup body 1. A leakage hole 10 is provided on the side of the discharge pipe 6 below the upper limit plate 11. The discharge pipe 6 is rotated to connect the leakage hole 10 on the discharge pipe 6 to the water collecting cup body 1. The condensed water in the water collecting cup body 1 can be discharged through the leakage hole 10 and the discharge pipe 6. The drainage is convenient and will not pollute the hands and the surrounding environment. The funnel airbag 1 2 can be inflated and inhaled, and the funnel airbag 12 is driven to vibrate during the inflation and inhalation process, which further facilitates the leakage of liquid at the bottom of the water collecting cup body 1, and sputum in the water collecting cup body 1 is easy to be discharged; one side of the discharge pipe 6 is connected to a piston cylinder 17, and the piston cylinder 17 is arranged above the manual switch valve 7.
