Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a ventilator anti-reflux device. Background Technology

[0002] In the medical field, ventilators are critical life support equipment, and their stability and reliability are essential for patient treatment. However, during use, condensation often occurs due to the humidity difference between the ventilator and the patient's airway. If these water droplets are not dealt with in time, they may flow back into the machine through the ventilator tubing, affecting the normal operation of the machine, or even causing malfunctions and shortening its service life. Therefore, it is particularly important to design a ventilator anti-backflow device that can effectively prevent water droplet backflow and is easy to clean.

[0003] However, existing technologies have the following problems in practical use:

[0004] Existing technologies are not conducive to promoting the condensation of water droplets during use, nor are they conducive to restricting the flow of water droplets inside the device. This may result in air and water vapor entering the ventilator, causing the internal parts of the ventilator to become damp, thereby affecting the service life of the ventilator.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a ventilator anti-reflux device, which is mainly used in scenarios that reduce ventilator reflux.

[0024] Example 1:

[0025] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 In order to promote the condensation of internal water vapor during use, a three-way pipe 2, a one-way valve 3, and a collection bottle 4 are provided.

[0026] One end of the intake pipe 1 is equipped with a three-way pipe 2 for assembly. A one-way valve 3 is threadedly connected to the bottom of the three-way pipe 2. A collection bottle 4 for storage is located at the bottom of the one-way valve 3. A flange 8 is fixedly connected to one end of the three-way pipe 2, and a threaded pipe 9 is also fixedly connected to the other end. The outer surface of the threaded pipe 9 is threadedly connected to the inner wall of the universal joint 7. A condenser pipe 10 is fixedly connected to one end of the flange 8. A guide pipe 11 is fixedly connected inside the condenser pipe 10. A spring 12 is snapped into the inner wall of the one-way valve 3, and a movable block 13 is snapped into the top of the spring 12. A bottle cap 14 is threadedly connected to the top of the collection bottle 4, and the outer surface of the bottle cap 14 is threadedly connected to the inner wall of the one-way valve 3. A sponge block 15 is snapped into the inner wall of the collection bottle 4. A scale line 16 is provided on the outer surface of the collection bottle 4. The flange 8 allows the three-way pipe 2 to be connected to the condenser pipe 10. The device is more secure, reducing oxygen leakage. The threaded tube 9 facilitates assembly. The condenser tube 10 promotes condensation of water vapor in the air inside the device, facilitating collection. The guide tube 11 increases the contact area between the air inside the device and the device, thus lowering the air temperature. The spring 12 allows the movable block 13 to return to its original position, achieving the aforementioned functions. The movable block 13 also blocks water droplets, reducing their re-entry into the device. The bottle cap 14 allows medical personnel to easily clean water droplets from the collection bottle 4. The sponge block 15 reduces the movement of water droplets inside the collection bottle 4. The scale line 16 allows medical personnel to easily check the water droplet content inside the collection bottle 4, increasing the device's convenience.

[0027] Example 2:

[0028] Please see Figure 1 and Figure 2 In order to make it easier to change the direction of oxygen delivery during use without affecting the oxygen delivery efficiency, an air inlet pipe 1 is provided.

[0029] One end of the air inlet pipe 1 is provided with a three-way pipe 2 for assembly. A pipe connector 6 is fixedly connected to one side of the air inlet pipe 1, and a universal tube 7 is fixedly connected to one end of the air inlet pipe 1. The pipe connector 6 allows for easy connection of the device to the ventilator. The universal tube 7 guides oxygen while delivering oxygen normally, preventing a decrease in oxygen delivery efficiency and increasing the practicality of the device.

[0030] Example 3:

[0031] Please see Figure 1 and Figure 3 In order to make it easier to connect the device to an oxygen mask during use, an outlet pipe 5 is provided;

[0032] One end of the three-way pipe 2 is provided with an outlet pipe 5, and one end of the outlet pipe 5 is fixedly connected to a sleeve 17. The inner wall of the sleeve 17 is threadedly connected to the outer surface of the condenser pipe 10. The sleeve 17 facilitates the assembly of the outlet pipe 5 with the device, while reducing oxygen leakage inside the device and increasing the device's protection.

[0033] In this invention, the working steps of the device are as follows:

[0034] First, the device is connected to the ventilator through the inlet tube 1. Second, when the patient exhales, the air enters the device through the outlet tube 5 and the condenser tube 10 on one side of the three-way tube 2 promotes the condensation of water vapor into water droplets. Then, the water droplets flow into the collection bottle 4 through the one-way valve 3 by gravity. The sponge block 15 inside the collection bottle 4 can reduce the sound of water droplets hitting the collection bottle 4 and reduce the shaking of water droplets inside the collection bottle 4. Finally, dry air enters the ventilator through the inlet tube 1 to prevent the ventilator from getting damp and to extend the service life of the ventilator.
