Description

Technical Field

[0001] This utility model relates to the field of breathing tubing technology for ventilators, and in particular to a novel ventilator tubing system. Background Technology

[0002] A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. The ventilator tubing system consists of multiple components, including multiple silicone breathing tubing, a heating chamber, and a water collection cup, which ensure that the ventilator delivers air to the lungs and expels air from the lungs.

[0003] During clinical use by medical personnel, the ventilator tubing system, except for the threaded interface at the water collection cup and connecting tube, mainly uses vertical insertion ports. During clinical use, the inlet and outlet tubing of the breathing circuit is easily loosened by pulling and gravity, and sometimes it will even fall off automatically. On the one hand, this will affect the airtightness of the breathing circuit, increasing the risk of respiratory tract infection for patients. On the other hand, because the connecting tube and the outlet of the breathing circuit often do not have heating guide wires, exhaled air will form condensation when it flows through these areas. As a result, the condensation in the breathing connecting tube and the outlet of the breathing circuit can flow back into the artificial airway due to changes in the position of the tubing.

[0004] How to provide a novel ventilator tubing system is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0018] This application provides a novel ventilator tubing system, which includes a breathing circuit assembly, an inlet tubing assembly, and an outlet tubing assembly. The breathing circuit assembly connects the patient to the inlet and outlet tubing assemblies, delivering gas from the ventilator to the patient's endotracheal tube. The inlet tubing assembly uses a humidifier to control the temperature of the inhaled gas, ensuring effective heating and humidification to prevent condensation and bacterial growth. The inlet tubing assembly also delivers oxygen from the ventilator to the breathing circuit assembly via a first and a second inlet tubing. The water collection cup in the ventilation tubing assembly is equipped with a water collection switch. Once the water level reaches a certain height as indicated by the scale markings, the switch is activated, allowing the water in the cup to drain through the lower drain pipe. This simplifies the process and prevents contamination of medical staff's hands and the surrounding environment when emptying the cup of bacterial condensate, thus mitigating the risk of hospital-acquired infections. The ventilation tubing assembly also features a check valve to prevent backflow of condensate when the tubing needs to be lifted or moved, thus preventing condensate from entering the patient's trachea and causing infection, and enhancing safety during use.

[0033] Combination Figures 1-3As shown, a novel ventilator tubing system according to an embodiment of the present invention includes: a novel ventilator 1 tubing system, characterized in that it includes: a breathing circuit assembly 4, the breathing circuit assembly 4 including a breathing tubing 41 and a respirator 42, the breathing tubing 41 being a three-way tubing, the first passage of the breathing tubing 41 being connected to one end of the respirator 42; an air intake tubing assembly 3, the air intake tubing assembly 3 including a first air intake tubing 31, a humidifier 32, and a second air intake tubing 33; one end of the first air intake tubing 31 is connected to the ventilator 1, the other end of the first air intake tubing 31 is movably connected to the air intake interface of the humidifier 32, one end of the second air intake tubing 33 is movably connected to the air outlet interface of the humidifier 32, and the other end of the second air intake tubing 33 is connected to the second passage of the breathing tubing 41. The system includes a first air outlet pipe 21, a water collection cup 22, a second air outlet pipe 24, a check valve 25, and a connecting pipe 26. One end of the first air outlet pipe 21 is connected to the ventilator 1, and the other end of the first air outlet pipe 21 is movably connected to the pipe interface 221 at the top of the water collection cup 22. A through hole is provided at the center of the bottom of the water collection cup 22, and a water collection switch 23 is provided on the through hole. One end of the second air outlet pipe 24 is movably connected to the pipe interface 221 at the top of the water collection cup 22, and the other end of the second air outlet pipe 24 is movably connected to one end of the check valve 25. The other end of the check valve 25 is movably connected to one end of the connecting pipe 26, and the other end of the connecting pipe 26 is movably connected to the third passage of the breathing tubing 41.

[0034] Specifically, this application provides a novel ventilator tubing system, which includes a breathing circuit assembly 4, an inlet tubing assembly 3, and an outlet tubing assembly 2. The breathing circuit assembly 4 is used to connect the patient to the inlet tubing assembly 3 and the outlet tubing assembly 2, delivering gas from the ventilator 1 to the patient's endotracheal tube through the breathing circuit assembly 4. The inlet tubing assembly 3 uses a humidifier 32 to control the temperature of the inhaled gas, ensuring heating and humidification effects to prevent condensation and bacterial growth. The inlet tubing assembly 3 also delivers oxygen from the ventilator 1 to the breathing circuit assembly 4 through a first inlet tubing 31 and a second inlet tubing 33. The venting tubing assembly 2 includes a water collection cup 22 equipped with a water collection switch 23. Once the water level reaches a certain height as indicated by the scale markings, the switch 23 is activated, allowing the water in the cup 22 to drain through the lower drain pipe. This simplifies the process and prevents contamination of medical staff's hands and the surrounding environment when emptying the cup, thus improving safety and minimizing the risk of cross-infection in the hospital. The venting tubing assembly 2 also features a check valve to prevent backflow of condensate when the tubing needs to be lifted or moved, thus preventing condensate from entering the patient's trachea and causing infection, further enhancing safety.

[0035] In some possible implementations, the other end of the first air outlet pipe 21 and the other end of the second air outlet pipe 24 are both provided with a first external thread 5, the other end of the second air inlet pipe 33 is provided with a second external thread 6, the other end of the connecting pipe 26 is provided with a third external thread 7, the pipe interface 221 at the top of the two water collection cups 22 are both provided with a first internal thread, the second passage is provided with a second internal thread, the third passage is provided with a third internal thread, the first external thread 5 is threadedly connected to the first internal thread, the second external thread 6 is threadedly connected to the second internal thread, and the third external thread 7 is threadedly connected to the third internal thread.

[0036] Specifically, threaded connections are installed at the joints of the tubing to prevent it from loosening due to pulling or gravity, thus avoiding any compromise to the tubing's airtightness. This reduces the risk of respiratory infections in patients, ensures normal oxygen delivery, and facilitates smooth operation during rescue and clinical use, thereby improving the safety of using the ventilator.

[0037] In some possible implementations, the outer wall of the water collection cup 22 is provided with water collection scale lines, and the water collection switch 23 includes a drain pipe and a shut-off valve. The drain pipe is fixed to the through hole of the water collection cup 22 and is connected to the water collection cup 22 through the through hole. The shut-off valve is fixed to the outer wall of the drain pipe.

[0038] Specifically, the water level markings on the water collection cup 22 allow medical staff to see the water content more clearly during daily observations, enabling them to more accurately determine when to drain the water from the water collection cup 22. The water discharge switch 23 makes draining the water from the water collection cup 22 more convenient, eliminating the need to remove the water collection cup 22 for pouring; the switch can be turned directly to drain the water, thus avoiding the risk of bacterial contamination of the water collection cup 22.

[0039] In some possible implementations, the first air intake pipe 31, the second air intake pipe 33, the first air outlet pipe 21 and the second air outlet pipe 24 are all made of PVC material, and the respirator 42 is made of PE material.

[0040] Specifically, using PVC material for pipes allows for clearer observation of whether there is water accumulation in the pipes, and its lighter weight makes it less likely for the pipes to fall off due to gravity.

[0041] In some possible implementations, the other end of the respirator 42 is connected to an external endotracheal tube, and the drain tube is connected to an external negative pressure suction tube.

[0042] Specifically, the ventilator 42 can connect the endotracheal tube and the ventilator 1 tubing, so that oxygen from the ventilator 1 can be delivered to the patient's body. The negative pressure suction tube can connect the water collection switch 23 to the negative pressure suction tube when it is necessary to empty the water collection cup 22, so that the negative pressure suction tube can directly suck out the water in the water collection cup 22.

[0043] In some possible implementations, the intake pipe assembly 3 further includes: a first pipe clamp, which is fixed to the first intake pipe 31 and / or the second intake pipe 33; and a first double pipe clamp, which is fixed to the first intake pipe 31 and / or the second intake pipe 33. The exhaust pipe assembly 2 further includes: a second pipe clamp, which is fixed to the first exhaust pipe 21 and / or the second exhaust pipe 24; and a second double pipe clamp, which is fixed to the first exhaust pipe 21 and / or the second exhaust pipe 24.

[0044] Specifically, the first and second tube clamps can fix the tubing to the bed to prevent the tubing from sagging due to gravity and causing water accumulation. The double tube clamps can connect the tubing of the ventilator 1 together to prevent the tubing from crossing and getting tangled.

[0045] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
