Water and oxygen in the air and other substances combine, easily cause the corrosion of metal parts, thereby affect the performance and service life of the anesthetic machine, and filtering water vapor can effectively reduce the corrosion risk, and the electronic elements may short circuit when encountering water, leading to malfunction of the anesthetic machine, and even damage. Water vapor filtering device can prevent water vapor from entering the electronic component area, ensure the normal operation of the electronic system of the anesthetic machine, and the concentration of anesthetic gas is crucial to the anesthetic effect. The presence of water vapor may dilute the anesthetic gas, causing the actual output anesthetic gas concentration to deviate from the set value, affecting the depth and effect of anesthesia. By filtering water vapor, the stability and accuracy of anesthetic gas concentration can be ensured, making the anesthesia process more controllable, and excessive water vapor may condense into water droplets in the gas circuit, accumulating in the pipeline or valve, etc., causing the gas circuit to be blocked or the airflow to be unsmooth. This not only affects the normal delivery of anesthetic gas, but also may cause pressure abnormalities and other problems, threatening patient safety, and filtering water vapor helps to keep the gas circuit unobstructed.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] With reference to Figures 1-5 A water vapor filtering device suitable for an anesthesia machine, comprising an upper tank body 1, an air inlet pipe 2 is formed on one side of the upper tank body 1, when water vapor filtering is needed, water vapor needs to enter the inside of the upper tank body 1 through the air inlet pipe 2, a separation sleeve 3 is fixedly connected inside the upper tank body 1, after the water vapor enters the inside of the upper tank body 1, it will not directly enter the inside of the separation sleeve 3, because the opening of the separation sleeve 3 is at the bottom, so the water vapor will move to the bottom of the separation sleeve 3 after entering the upper tank body 1, and then move upward from the bottom to enter the inside of the separation sleeve 3, the top of the separation sleeve 3 is communicated with an air outlet pipe 4, after the water vapor moves upward from the bottom, it will be discharged through the air outlet pipe 4, so that the water vapor can enter and exit in the inside of the upper tank body 1, the air outlet pipe 4 is communicated with the surface of the upper tank body 1, a plurality of water absorbing materials 5 are fixedly connected inside the air outlet pipe 4, when the water vapor passes through the separation sleeve 3 from bottom to top, it can absorb the water in the water vapor through the water absorbing materials 5, the water absorbing materials 5 are generally water absorbing sponges, water absorbing silica gels and other water absorbing materials 5 that do not affect the use of anesthetics, further water removal, after the water vapor is removed by the water absorbing materials 5, it will be discharged through the air outlet pipe 4, so that the water vapor can be continuously removed, the bottom of the upper tank body 1 is threadedly connected with a lower tank body 6, the lower tank body 6 can collect condensed water, and the bottom of the lower tank body 6 is blocked, so that the water vapor can only flow in the inside of the upper tank body 1 and the lower tank body 6, the surfaces of the upper tank body 1 and the lower tank body 6 are fixedly connected with protruding rings 7, the protruding rings 7 can conveniently fix the upper tank body 1 and the lower tank body 6, which is convenient to use, a mounting mechanism 8 is arranged between the two protruding rings 7, the mounting mechanism 8 can conveniently fix the positions of the upper tank body 1 and the lower tank body 6, which will not be separated when in use, and when not in use, the mounting mechanism 8 is opened, and then the upper tank body 1 and the lower tank body 6 are separated for cleaning.

[0024] Further, the mounting mechanism 8 comprises clamping grooves 801 opened on the surface of the protruding ring 7, and a stabilizing rod 802 is slidably connected between the two clamping grooves 801. When it is necessary to fix the upper tank body 1 to the lower tank body 6, the upper tank body 1 and the lower tank body 6 need to be rotated first, and then fixed by screwing. After fixing, the two clamping grooves 801 can be located on the same axis, and then the two clamping grooves 801 are limited by the stabilizing rod 802, so that the two protruding rings 7 cannot rotate, thereby preventing the upper tank body 1 and the lower tank body 6 from being separated.

[0025] Further, the top of the upper protruding ring 7 is fixedly connected with a growth block 803, and a T-shaped accommodating groove 804 is opened on the top of the growth block 803. An anti-rotation block 805 is slidably connected in the accommodating groove 804. After the upper tank body 1 and the lower tank body 6 are fixed, the anti-rotation block 805 can be accommodated in the accommodating groove 804 on the top of the growth block 803.

[0026] Further, the anti-rotation block 805 is fixedly connected with the stabilizing rod 802. When the anti-rotation block 805 is fixed with the stabilizing rod 802, the anti-rotation block 805 and the stabilizing rod 802 are sent into the clamping groove 801 from the accommodating groove 804 after the upper tank body 1 and the lower tank body 6 are fixed. In this way, the stabilizing rod 802 cannot be easily separated from the clamping groove 801, and the stabilizing rod 802 can also be conveniently inserted into the clamping groove 801, so that the upper tank body 1 and the lower tank body 6 are more stable after being fixed and are not easy to separate.

[0027] Further, the cross-sectional area of the partition sleeve 3 is larger than that of the air inlet pipe 2. The cross-sectional area of the partition sleeve 3 is larger than that of the air inlet pipe 2, which can be used to slow down the air flow rate, increase the condensation time, and make the water removal effect better.

[0028] Further, the two protruding rings 7 are provided with a sealing ring 9, which is located between the two protruding rings 7 to seal the gap between the upper tank body 1 and the lower tank body 6, preventing water vapor leakage and preventing the problem of water vapor recovery.

[0029] In summary:

[0030] When it is necessary to filter water vapor containing anesthetic, the water vapor is sent into the interior of the upper tank 1 through the air inlet pipe 2. Then, the water vapor enters the interior of the partition sleeve 3 from below, where it is absorbed by the absorbent material 5 inside the partition sleeve 3. After dehydration, the steam can be discharged through the air outlet pipe 4 on the side of the partition sleeve 3, thus completing the dehydration and recovery of the water vapor. During use, condensate will enter the interior of the lower tank 6 for collection. When it is necessary to disassemble and clean after long-term use, the stabilizing rod 802 and the anti-rotation block 805 can be moved upwards first. The stabilizing rod 802 is disengaged from the slot 801 by the receiving groove 804 on the extension block 803, thereby opening the fixation of the two protruding rings 7. The upper tank 1 and the lower tank 6 can be rotated apart to open the interior. The sealing ring 9 between the two protruding rings 7 increases the sealing of the upper tank 1 and the lower tank 6 after they are fixed, ensuring the filtration of water vapor. After cleaning, the sealing ring 9 is placed between the two protruding rings 7, and then the upper tank 1 and the lower tank 6 are rotated. The stabilizing rod 802 is then sent into the slot 801 through the anti-rotation block 805 to fix the two protruding rings 7, allowing it to continue to be used. Through the above structure, when filtering water vapor, the air flow channel is increased by the partition sleeve 3, giving the water vapor a longer cooling time and heat dissipation area, improving cooling efficiency, and allowing the water vapor to cool the condensate and remove water vapor from the gas.
