Description

Technical Field

[0001] This invention relates to the field of ventilator technology, and in particular to a high-flow humidification therapy device for treating water accumulation in tubing and the ventilator thereof. Background Technology

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used in respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] The air supply for the ventilator is delivered to the patient through the ventilator tubing.

[0004] In mechanical ventilation, most hospitals use heated humidifiers to increase the humidity and temperature of the gas inhaled by patients. Heating and humidifying the inhaled gas is to reduce or eliminate the humidity difference that occurs when patients inhale dry medical gas. However, since the ambient temperature is generally lower than the gas temperature in the ventilator tubing, water vapor will be cooled in the tubing, resulting in condensation in the breathing tubing.

[0005] Existing ventilator tubing has a water collection cup in the middle to collect condensate. When the condensate reaches a certain amount, it must be cleaned in time. Otherwise, this humidified environment is conducive to bacterial colonization. Condensate is an excellent bacterial reservoir where pathogens can easily parasitize and multiply. At the same time, it increases airway resistance and affects patient ventilation. Furthermore, if condensate is left for too long, it will promote bacterial growth and may flow into the patient's airway, increasing the incidence of ventilator-associated pneumonia and increasing the patient's mortality rate.

[0006] When the condensate cup of a ventilator is removed, the condensate inside the cup may contain pathogens that could easily contaminate the local environment, medical staff, and surrounding patients, causing nosocomial infections.

[0007] To prevent condensate from flowing back, clinical medical staff need to wear gloves and manually remove the collection cup every so often to empty the condensate into the trash can, which is then covered. This is extremely labor-intensive. Ventilators are mostly used in intensive care units, and staff may forget to empty the condensate when they are busy, so they need to be reminded in time. Emptying the condensate may cause infection of staff and environmental pollution, and may also contaminate the surrounding ward environment. Some equipment may experience pressure fluctuations in the ventilator tubing due to the removal of the bottle. Summary of the Invention

The condensate inlet 53 is connected to the condensate collection chamber, while the slide plate completely blocks the water vapor outlet 54. The condensate is collected from the expansion pipe into the connecting longitudinal pipe 5, and then flows into the middle, left, or right water accumulation chamber 27 through the connecting longitudinal pipe 5. The condensate flows through the condensate channel 38 into the first anti-backflow chamber 15, the second anti-backflow chamber 23, or the third anti-backflow chamber 28, and then flows through the first condensate through hole 16. The condensate enters the first condensate transition space 17, the second condensate transition space 24, or the third condensate transition space 29. The condensate then flows through the second condensate through-hole 19 into the first ultraviolet sterilization chamber 18, the second ultraviolet sterilization chamber 25, or the third ultraviolet sterilization chamber 30 for sterilization. After sterilization, the condensate flows through the third condensate through-hole 20 into the first condensate collection chamber 21, the second condensate collection chamber 26, or the third condensate collection chamber 31. At this point, it flows directly through the condensate inlet 53 into the hollow support frame 40, where it is collected inside.

[0074] When a certain amount of condensate is collected, the liquid level sensor detects that the liquid level inside the hollow support frame 40 is higher than the set threshold, and the condensate evaporation process is started.

[0075] During the condensate evaporation process, the liquid level sensor detects that the liquid level inside the hollow support frame 40 is higher than a set threshold. The liquid level sensor transmits the liquid level information to the controller, which then controls the cylinder 42 to start working. The controller also controls the electric heating device 41 to start working. When the piston rod of the cylinder 42 moves the sliding plate to completely block the condensate inlet 53, the sliding plate is in contact with the inner wall of the hollow support frame 40. The sliding plate does not block the steam outlet 54, which is open to the outside. This heats the condensate inside the hollow support frame 40. The heated condensate can be ≤100℃ to accelerate evaporation. The water vapor generated by the evaporating condensate is discharged to the outside environment through the steam outlet 54. When the condensate inside the hollow support frame 40 is almost completely evaporated, the electric heating device 41 stops working. In sequence, condensate is collected by expansion pipe into connecting longitudinal pipe 5, and then flows into the middle, left or right water accumulation cavity 27 through connecting longitudinal pipe 5. Condensate flows into the first anti-backflow chamber 15, the second anti-backflow chamber 23 or the third anti-backflow chamber 28 through condensate channel 38, and then flows into the first condensate transition space 17, the second condensate transition space 24 or the third condensate transition space 29 through the first condensate through hole 16. Condensate then flows into the first ultraviolet sterilization chamber 18, the second ultraviolet sterilization chamber 25 or the third ultraviolet sterilization chamber 30 through the second condensate through hole 19 for sterilization and disinfection. After sterilization and disinfection, condensate flows into the first condensate collection chamber 21, the second condensate collection chamber 26 or the third condensate collection chamber 31 through the third condensate through hole 20.

[0076] When the liquid level sensor detects that the liquid level inside the hollow support frame 40 is higher than the set threshold, the liquid level sensor transmits the liquid level information to the controller, and the controller controls the electric heating device 41 to stop working.

[0077] When the temperature sensor detects that the temperature inside the hollow support frame 40 is lower than the set threshold (at this time, the internal temperature of the hollow support frame 40 after heating and evaporation has cooled to normal), the temperature sensor transmits the temperature information to the controller. The controller controls the cylinder 42 to start working again. The piston rod of the cylinder 42 drives the slide plate to move until it completely blocks the water vapor outlet 54. The condensate inlet 53 is connected to the condensate collection chamber, and the condensate collection process is normal. This cycle continues.

[0078] This high-flow respiratory humidification therapy device, which can handle the water accumulation in the pipeline, does not require removing the water collection cup. The evaporation process of the condensate can be started directly. Since the condensate has been sterilized and disinfected, even if the condensate evaporates into the external environment, it will not pollute the local environment, medical staff, or surrounding patients.

[0079] In clinical practice, medical staff no longer need to wear gloves. They can manually remove the water collection cup every once in a while and pour out the condensate into the trash can, which greatly saves their workload and eliminates the problem of forgetting to empty the condensate when they are busy. This has brought great convenience and reform to medical staff.

[0080] During the normal collection of condensate and the cycle of starting the condensate evaporation process, the gas flow detector 52 monitors the gas flow in the built-in tube 3 in real time for possible pressure fluctuations in the ventilator tubing, and feeds it back to the controller. The controller controls the flow regulating valve 50 to adjust the intake flow in real time to ensure a high flow of high-speed air / oxygen mixture.

[0081] The movable legs facilitate the fixation and support of the hollow support frame 40 and the ventilator tubing. The movable legs can be fixed to the edge of the bed or other locations to prevent the ventilator tubing from becoming tangled, bent, or deformed. The height of the movable legs is adjustable, making it easy to adjust the height of the hollow support frame 40 and the ventilator tubing to suit the actual situation.

[0082] When the ventilator tubing is tilted, due to the condensate evaporation process, not much condensate will accumulate inside the middle, left, or right water accumulation chamber 27 from beginning to end. The condensate evaporates in time. Therefore, even if the ventilator tubing is tilted at various angles, the condensate will only collect in the middle, left, or right water accumulation chamber 27 and will not enter the internal tube 3, nor will it flow into the patient's airway or humidifier 2, thus avoiding the occurrence of related pneumonia. In this case, the condensate backflow prevention function is achieved.

[0083] When the ventilator tubing is accidentally inverted 180°, the spherical sealing block 35 slides into the upper receiving block 32, blocking the upper condensate channel 36. This prevents condensate from entering the internal tube 3 from the middle, left, or right water accumulation chamber 27, and also prevents it from flowing into the patient's airway or humidifier 2, thus avoiding the occurrence of related pneumonia. In this situation, the condensate backflow prevention function is achieved.

[0084] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
