Technical Field

[0001] The utility model relates to the technical field of ventilator pipelines, and particularly relates to a ventilator pipeline with a water-blocking air valve. Background Technique

[0002] In modern clinical medicine, as an effective means to artificially replace the function of independent ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and play a very important role 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 extend the lives of patients;

[0003] The ventilator pipeline is used to convey gas. Among them, a water collecting cup is usually installed on the ventilator pipeline to collect the condensed water in the respiratory pipeline.

[0004] However, the existing ventilator pipeline separates liquid and gas through a water collecting cup. This structure is prone to tilt or even turn over, which may cause the condensed water in the water collecting cup to flow back into the respiratory pipeline, posing a safety hazard; therefore, it does not meet the existing requirements, and for this reason, we propose a ventilator pipeline with a water-blocking air valve. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Please refer to Figure 1-6 , an embodiment provided by the present utility model: A ventilator pipeline with a water-blocking air valve, including: a main body 1 of the ventilator pipeline, and a valve body 2 for water-blocking and air-permeating is installed between the main bodies 1 of the ventilator pipeline;

[0028] The valve body 2 further includes:

[0029] An inlet barrier end 3, which is installed at one end of the valve body 2, and the inlet barrier end 3 is communicated with the main body 1 of the ventilator pipeline;

[0030] A gas discharge end 4, which is installed at the other end of the valve body 2, and the gas discharge end 4 is communicated with the main body 1 of the ventilator pipeline;

[0031] An air cavity 8, which is opened inside the valve body 2, and the air cavity 8 is communicated with the inlet barrier end 3 and the gas discharge end 4. A limit assembly seat 7 is provided on the inner wall of the air cavity 8 near one end of the inlet barrier end 3, and an EPTFE membrane 9 is provided above the limit assembly seat 7.

[0032] The inlet barrier end 3 is used to send the medium containing gas and liquid into the air cavity 8. The gas-liquid medium is separated by the microporous structure and physical properties of the membrane body in the EPTFE membrane 9, so that the gas enters the air cavity 8, while the liquid stays outside. The gas is then discharged from the gas discharge end 4 into the main body 1 of the ventilator pipeline for the ventilator intake operation.

[0033] Please refer to Figure 6 , a pressing block 10 is provided at one end of the inlet barrier end 3 close to the air cavity 8. A through hole is opened in the middle of the pressing block 10, and the outer edge of the lower surface of the pressing block 10 presses on the outer edge of the upper surface of the EPTFE membrane 9.

[0034] When entering the combination of the barrier end 3 and the valve body 2, the pressing block 10 can just press on the outer edge of the upper surface of the EPTFE membrane 9, while the bottom of the EPTFE membrane 9 is restricted by the limit assembly seat 7, so that the membrane body is located between the pressing block 10 and the limit assembly seat 7, achieving the effect of fixing and restricting the EPTFE membrane 9. The liquid-containing gas then enters the membrane body through the through hole in the pressing block 10, without affecting the normal air intake operation.

[0035] When disassembling, the barrier end 3 is separated from the valve body 2, and the pressing block 10 is separated together, so that the membrane body is no longer restricted, facilitating the user to take it out and replace it.

[0036] Furthermore, the combined thickness of the EPTFE membrane 9 and the pressing block 10 is the same as the depth of the limit assembly seat 7 embedded in the air cavity 8.

[0037] The EPTFE membrane 9 and the pressing block 10 can just be embedded on the limit assembly seat 7 and be flush with the upper opening of the air cavity 8, so that the first assembly plate 6 can be smoothly assembled at the end of the valve body 2, improving the sealing performance.

[0038] Please refer to Figure 2 、 Figure 5 On the outer walls at both ends of the valve body 2, annularly distributed screw holes 12 are provided. One end of the barrier end 3 close to the valve body 2 is provided with a first assembly plate 6, and one end of the gas discharge end 4 close to the valve body 2 is provided with a second assembly plate 13. The first assembly plate 6 and the second assembly plate 13 are respectively assembled at both ends of the valve body 2 through assembly bolts 14.

[0039] Through the assembly bolts 14, the first assembly plate 6 and the second assembly plate 13 can be combined with the valve body 2 to form a complete valve structure. This assembly structure is detachable, facilitating the user to disassemble and replace.

[0040] Please refer to Figure 1 、 Figure 2 On the outer walls of the barrier end 3 and the gas discharge end 4, pipeline combination ends 5 for combining and assembling with the ventilator pipeline are provided. On the outer walls of the first assembly plate 6 and the second assembly plate 13, air holes 11 for communicating with the pipeline combination ends 5 are provided.

[0041] The pipeline combination ends 5 are used to connect the pipeline of the ventilator. After the valve body 2 filters the liquid, it is convenient for the gas to enter the pipeline for transportation.

[0042] Please refer to Figure 6 As shown in, on the inner wall of the pipeline combination end 5, a sealing ring 15 is provided.

[0043] The sealing ring 15 is used to improve the sealing performance between the pipeline combination end 5 and the ventilator pipeline, making it not easy to leak between the two.

[0044] Working principle: When in use, place the EPTFE membrane 9 on the limit assembly seat 7, insert the pressing block 10 of the first assembly plate 6 into the opening, press the pressing block 10 on the EPTFE membrane 9, and fix and limit the EPTFE membrane 9.

[0045] Fix the first assembly plate 6 and the second assembly plate 13 at both ends of the valve body 2 through assembly bolts 14, and install the main body 1 of the ventilator pipeline in the two pipeline combination ends 5.

[0046] When the ventilator is operating, draw the liquid-containing gas to enter the blocking end 3 and then enter the EPTFE membrane 9. The EPTFE membrane 9 separates the liquid and gas through its microporous structure and physical properties. The gas enters the gas discharge end 4 from the gas cavity 8 and enters through the ventilator pipeline at this place for the air supply operation.

[0047] After operating for a certain period of time, remove the two assembly plates by removing the bolts, pour out the residual liquid inside, remove and replace the membrane body, clean and disinfect the entire valve body 2, and replace it with a new membrane body for the next operation.

[0048] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
