[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] The existing oxygen inhalation tube that can prevent the backflow of water in the humidification bottle can limit the backflow of water in the humidification bottle into the oxygen inhalation tube by providing a valve body between the humidification bottle and the oxygen inhalation tube, thereby preventing accidental inhalation. However, in actual use, since the valve body needs to switch between open and closed, and there are only two working states, there is a certain impact on the use of humidified dry oxygen in the humidification bottle. Utility Model Content

[0007] In order to overcome the problem that the existing oxygen inhalation tube that can prevent water backflow in the humidification bottle needs to switch between open and closed during actual use, and there are only two working states, which is not conducive to using the humidification bottle to moisten dry oxygen during continuous oxygen supply, the embodiment of the present application provides an anti-backflow oxygen humidification bottle, by arranging an anti-backflow column with first guiding curved surfaces processed on the outer walls of both ends inside the anti-backflow joint, when one end of the anti-backflow joint is threadedly connected to the cover joint on one side of the bottom of the inlet and outlet gas bottle cover, and one end of the pipe joint is connected to the oxygen pipe, during the patient's oxygen inhalation, the outer wall of the anti-backflow column can be fitted with the inner wall of the anti-backflow joint to isolate the four sides of the two ends of the anti-backflow joint, and the anti-backflow column can perform the connecting function of the centers of the two ends of the anti-backflow joint, so that when the patient absorbs dry oxygen moistened by the humidification bottle body through the oxygen inhalation tube, the water between the humidification bottle body and the oxygen pipe can be prevented from flowing back in both directions without affecting the patient's continuous oxygen inhalation. The present application is also applicable to the vehicle-mounted oxygen cylinder of an emergency vehicle.

[0026] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0027] Example 1

[0028] This embodiment introduces the specific structure of the anti-backflow oxygen humidification bottle. Figure 1-Figure 4 As shown, it includes a humidification bottle body 1, an inlet and outlet gas bottle cover 2 arranged on the top of the humidification bottle body 1, and an anti-backflow joint 3 arranged on one side of the bottom of the inlet and outlet gas bottle cover 2, an anti-backflow column 7 is arranged inside the anti-backflow joint 3, and the outer sides of both ends of the anti-backflow column 7 are processed with a first guide curved surface 11, one end of the anti-backflow joint 3 is processed with a pipe joint 4, and the outer wall of the bottom of the inlet and outlet gas bottle cover 2 is processed with a cover joint 6;

[0029] Among them, by processing the first guide curved surface 11 on the outer wall of the two ends of the backflow prevention column 7, the cross-section of the backflow prevention column 7 is a rectangle in the center and an isosceles trapezoid on both sides. When the outer wall of the backflow prevention column 7 is fitted with the inner wall of the backflow prevention joint 3, the backflow prevention column 7 can be used to cut off the four sides of the two ends of the backflow prevention joint 3, and the backflow prevention column 7 performs the connecting function of the two ends of the backflow prevention joint 3. When the water on one side of the oxygen tube flows back to the inside of the humidification bottle body 1, it is blocked by one end of the backflow prevention column 7, and at the same time, the water inside the humidification bottle body 1 is blocked when it flows back to the inside of the oxygen tube;

[0030] Secondly, in order to prevent water droplets from accumulating on the inner wall of the anti-backflow column 7, which would affect the flow of the humidified gas inside the anti-backflow column 7 and thus reduce the oxygen inhalation effect of the patient, Figure 4 As shown, the second guide curved surface 12 is processed on both sides of the interior of the anti-backflow column 7. By setting the width of the second guide curved surface 12 at the center of the anti-backflow column 7 to be larger than the width of the second guide curved surface 12 at one end of the anti-backflow column 7, the channel inside the anti-backflow column 7 is composed of two truncated cone grooves with isosceles trapezoidal cross-sections, ensuring that water droplets at the center of the anti-backflow column 7 can flow to both ends.

[0031] By adopting the above technical solution:

[0032] The above design is to set an anti-backflow column 7 with first guiding curved surfaces 11 processed on the outer walls of both ends inside the anti-backflow joint 3. When one end of the anti-backflow joint 3 is threadedly connected to the cover joint 6 on one side of the bottom of the inlet and outlet gas cylinder cover 2, and one end of the pipe joint 4 is connected to the oxygen tube, the outer wall of the anti-backflow column 7 can be fitted with the inner wall of the anti-backflow joint 3 during the patient's oxygen inhalation, so as to cut off the surrounding areas of the two ends of the anti-backflow joint 3, and the anti-backflow column 7 can perform the connecting function of the center of the two ends of the anti-backflow joint 3, so that the water on one side of the oxygen tube is blocked by one end of the anti-backflow column 7 when it flows back to the inside of the humidification bottle main body 1, and at the same time, the water inside the humidification bottle main body 1 is blocked when it flows back to the inside of the oxygen tube, so that when the patient absorbs dry oxygen moistened by the humidification bottle main body 1 through the oxygen inhalation tube, the water between the humidification bottle main body 1 and the oxygen tube is prevented from flowing back in both directions, and the anti-backflow effect is good without affecting the patient's continuous oxygen inhalation.

[0033] Example 2

[0034] Based on Example 1, this example introduces the specific structure of the anti-backflow joint 3. The bottom of the anti-backflow joint 3 is processed with a branch pipe head 10, one end of the branch pipe head 10 is provided with a collecting bottle 5, and a gap is left between the two sides of the center of the anti-backflow column 7 and the opening at one end of the branch pipe head 10;

[0035] When one end of the anti-backflow joint 3 is threaded inside the cap joint 6, the branch pipe head 10 is in a vertical downward state. At this time, the water inside the anti-backflow joint 3 blocked by the anti-backflow column 7 passes through the gap between the first guide curved surface 11 on the anti-backflow column 7 and one end of the branch pipe head 10 and flows down from the inside of the branch pipe head 10, so as to be collected inside the collection bottle 5.

[0036] Secondly, in order to position the backflow prevention column 7 inside the backflow prevention joint 3, a fixed size gap is left between the two sides of the center of the backflow prevention column 7 and the opening at one end of the branch pipe head 10, such as Figure 3 As shown, a positioning rod 9 is processed on the inner wall of the bottom of the collecting bottle 5, and a positioning ring groove 8 is processed on the outer wall at the center of the anti-backflow column 7. After the collecting bottle 5 is threadedly connected to the inside of the branch pipe head 10, one end of the positioning rod 9 can be extended into the inside of the anti-backflow joint 3 through the branch pipe head 10 and fall into the inside of the positioning ring groove 8, thereby limiting the left and right movement of the anti-backflow column 7 inside the anti-backflow joint 3.

[0037] By adopting the above technical solution:

[0038] The above design processes a branch pipe head 10 at the bottom of the anti-backflow joint 3, and connects the collecting bottle 5 with the internal thread of the branch pipe head 10, so that a fixed size gap is left between the two sides of the center of the anti-backflow column 7 and the opening at one end of the branch pipe head 10. In the process of the anti-backflow column 7 preventing water from flowing in both directions at the anti-backflow joint 3, the accumulated water can be guided to the inside of the branch pipe head 10, and finally the collection work is completed inside the collecting bottle 5, which is conducive to preventing the long-term accumulation of water and causing bacterial growth;

[0039] At the same time, when the collecting bottle 5 is connected to one end of the branch pipe head 10, one end of the positioning rod 9 is extended into the interior of the anti-backflow joint 3 through the branch pipe head 10 and falls into the interior of the positioning ring groove 8, which can limit the left and right movement of the anti-backflow column 7 inside the anti-backflow joint 3, thereby achieving the effect of fixing the anti-backflow column 7 inside the anti-backflow joint 3 and ensuring that the gap size between the two sides of the center of the anti-backflow column 7 and the opening at one end of the branch pipe head 10 is fixed.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
