Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more particularly to a telescopic oxygen inhalation tube. Background Art

[0002] Oxygen inhalation is a commonly used treatment method in clinical practice. It is used to correct hypoxia, increase the level of arterial oxygen partial pressure and oxygen saturation, and promote metabolism. It is one of the important methods for auxiliary treatment of various diseases. At present, the equipment used for oxygen inhalation mainly includes oxygen source, oxygen humidifier, and oxygen inhalation tube. Among them, the oxygen humidifier is used to humidify oxygen, that is, to add water vapor to oxygen to keep the patient's trachea moist, increase the oxygen intake time and thus increase the oxygen intake, improve blood oxygen saturation, and prevent the occurrence of cerebral hypoxia.

[0003] Although humidifying oxygen with an oxygen humidifier can keep the patient's trachea moist, there will be small water droplets when the temperature of the tube wall is low. The small water droplets will enter the patient's respiratory tract with the oxygen and choke the patient or irritate the patient's respiratory tract; in response to this problem, the prior art has designed many solutions to solve this problem. For example, the Chinese invention patent (CN105413032B) discloses a telescopic oxygen inhalation tube, which is provided with a gas-water separation sheet to separate oxygen from the water vapor therein, and discharge the separated liquid through a drainage pressure relief valve. A problem with this structure is that by providing the gas-water separation sheet, the pre-humidified oxygen will be turned into a dry state again, so that the humidity of the oxygen cannot meet the patient's needs. After a long time, the patient's trachea will become very dry. Moreover, the use of this structure will waste the water vapor generated by the oxygen humidifier.

[0004] Based on the above problems, the applicant has invented a new telescopic oxygen inhalation tube. Summary of the invention

[0005] The purpose of the present invention is to provide a telescopic oxygen absorption tube, which can heat the temperature inside the tube and reduce the generation of small water droplets; at the same time, the oxygen absorption tube can use the generated small water droplets to humidify oxygen, reducing the amount of water vapor generated by the oxygen humidifier.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a retractable oxygen inhalation tube, comprising a lower connecting tube and two nasal suction tubes, both of which are connected to the lower connecting tube; an inner tube is provided at a position of the lower connecting tube away from the nasal suction tube, and a receiving tube is sleeved on the outer wall of the inner tube; an upper connecting tube is provided on the top of the receiving tube; a sponge is provided at the end of the inner tube away from the lower connecting tube, and the sponge is located in the receiving tube; a bracket is fixedly provided inside the inner tube, and a heating rod is provided on the bracket, and the heating part of the heating rod is located in the cavity between the inner tube and the receiving tube.

[0007] By adopting the above technical solution, a bracket is installed in the inner tube, a heating rod is installed on the bracket, and the heating rod is located in the cavity between the accommodating tube and the inner tube. In this way, the oxygen inhaled by the patient can be heated and the loss of water vapor in the oxygen can be reduced.

[0008] The present invention is further configured as follows: a plurality of capillary strings are also arranged on the sponge, and ends of the plurality of capillary strings away from the sponge are located at the bottom of the containing tube.

[0009] By adopting the above technical solution, multiple capillary strings are connected to the sponge, and the other end of the capillary string is located at the bottom of the containing tube, so that small water droplets generated on the wall of the containing tube flow to the bottom of the containing tube, and the water is sucked into the sponge through the capillary effect of the capillary string, thereby achieving the effect of humidifying oxygen through small water droplets.

[0010] The present invention is further configured as follows: a plurality of heat sinks are provided on the side wall of the heating section of the heating rod.

[0011] By adopting the above technical solution, a plurality of heat sinks are fixedly installed on the side wall of the heating section of the heating rod, which can increase the convection heat exchange area between the heating rod and the oxygen, so that the heat generated by the heating rod can fully exchange heat with the oxygen, further reducing the amount of water vapor condensation in the oxygen.

[0012] The present invention is further configured such that: the upper connecting pipe is spiral-shaped.

[0013] By adopting the above technical solution, the upper connecting tube is set in a spiral shape, which not only facilitates the expansion and contraction of the upper connecting tube, but also makes it difficult to bend, so that the oxygen absorption tube always maintains a normal state.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. Install a bracket in the inner tube, install a heating rod on the bracket, and the heating rod is located in the cavity between the receiving tube and the inner tube, so that the oxygen inhaled by the patient can be heated to reduce the loss of water vapor in the oxygen;

[0016] 2. Connect multiple capillary strings to the sponge, and the other end of the capillary string is located at the bottom of the receiving tube, so that the small water droplets generated on the wall of the receiving tube flow to the bottom of the receiving tube, and the water is sucked into the sponge through the capillary effect of the capillary string, thus achieving the effect of humidifying oxygen through the small water droplets;

[0017] 3. The upper connecting tube is set to a spiral shape, which is not only convenient for the upper connecting tube to be extended and retracted, but also not easy to bend, so that the oxygen absorption tube always maintains a normal state. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figure 1-3 The present invention is described in further detail.

[0023] Embodiment: A telescopic oxygen inhalation tube, such as Figures 1 to 3 As shown, it includes a lower connecting tube 7 and two nasal suction tubes 6, and the two nasal suction tubes 6 are connected to the lower connecting tube 7; the lower connecting tube 7 is connected to an inner tube 5 at a position away from the nasal suction tube 6, and a receiving tube 4 is sleeved on the outer wall of the inner tube 5; the top of the receiving tube 4 is connected to the upper connecting tube 1; a sponge 10 is installed at the end of the inner tube 5 away from the lower connecting tube 7, and the sponge 10 is located in the receiving tube 4; a bracket 9 is fixedly installed inside the inner tube 5, and the shape of the bracket 9 is as shown in FIG. Figure 3 As shown, there is a circular plate in the middle, which is supported by connecting several support rods; a heating rod 3 is fixedly mounted on the bracket 9, and the heating part of the heating rod 3 is located in the cavity between the inner tube 5 and the containing tube 4, so as to avoid heating the sponge 10 and causing the water on the sponge 10 to be lost.

[0024] Preferably, in this embodiment, a plurality of capillary strings 8 are connected to the sponge 10 , and the capillary strings 8 are selected from cotton ropes and hemp ropes. The ends of the plurality of capillary strings 8 away from the sponge 10 are located at the bottom of the containing tube 4 .

[0025] This embodiment is preferred, such as Figure 1 and Figure 2 As shown, a plurality of heat sinks 2 are fixedly connected to the side wall of the heating section of the heating rod 3 .

[0026] This embodiment is preferred, such as Figure 1 As shown, the upper connecting pipe 1 is spiral.

[0027] In this embodiment, a battery (not marked in the figure) is also provided on the containing tube 4 for supplying power to the heating rod 3 .

[0028] Working principle: When the patient uses the telescopic oxygen inhalation tube, the upper connecting tube 1 is connected to the humidifying device and the sponge 10 is kept moist; when the patient inhales oxygen, the oxygen performs convection heat exchange with the heating rod 3 and the heat sink 2, thereby heating the oxygen. When passing through the sponge 10, the sponge 10 humidifies the oxygen and finally inhales it into the patient's lungs; this not only ensures the temperature of the oxygen, but also ensures the humidity of the oxygen; however, when used for a long time, the side wall of the containing tube 4 will also perform convection heat exchange with the oxygen, which can easily cause a small part of the water vapor in the oxygen to condense into small water droplets; the small water droplets eventually gather at the bottom of the containing tube 4, and under the capillary action of the capillary rope 8, the condensed water is absorbed into the sponge 10, thus achieving the effect of humidifying the oxygen through the condensed water.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
