Description

Technical Field

[0001] The invention relates to the technical field of oxygen supply, and in particular to a humidification and heat preservation auxiliary device for an oxygen absorption tube. Background Art

[0002] Oxygen inhalation 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. Such as respiratory failure, chronic tracheitis, cerebrovascular disease, and coronary heart disease. Those with no obvious clinical hypoxia symptoms may also have oxygen debt and abnormal microcirculation metabolism, and therefore may need oxygen inhalation. Such as some patients before and after surgical operations, patients with massive hemorrhage shock, patients with poor fetal heart sounds, or patients with prolonged labor during delivery, etc.

[0003] The oxygen produced by the oxygen machine is transported to the patient's nose through an oxygen tube, but the oxygen produced by the oxygen machine is very dry, and the patient will experience severe discomfort after absorbing it, so the oxygen needs to be humidified. The existing technology generally uses an oxygen humidifier for humidification, but the temperature of the humidified oxygen is low, which will also cause discomfort to the patient.

[0004] To this end, relevant practitioners have designed a corresponding humidification and heat preservation device, which collects the oxygen after it escapes through the water through the corresponding pipe, and heats the pipe in a water bath to achieve the humidification and heat preservation of the oxygen. In this device, the position of the middle pipe is fixed, and the area where the water bath is heated is fixed. If you want to adjust the temperature of the output oxygen, you can only adjust the temperature of the heating element of the heating box, and heating or cooling requires a certain reaction time, so it is difficult to change the temperature of the oxygen in the middle pipe in time. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention proposes a humidification and heat preservation auxiliary device for an oxygen absorption tube to solve the technical problem mentioned in the above background technology that the oxygen temperature can only be changed by adjusting the heating element in the existing oxygen absorption humidification and heat preservation device.

DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0030] Please also read Figure 1-Figure 4 , this embodiment provides a humidification and heat preservation auxiliary device for an oxygen absorption tube, comprising a housing 1, a humidification box 2, an oxygen inlet tube 3, a heating box 4, a heating tube 5, an intermediate tube 6, a clamping mechanism 7 and a driving mechanism 8;

[0031] The humidifying box 2 and the heating box 4 are respectively arranged in the outer shell 1, and the top of the humidifying box 2 is respectively provided with an air inlet 21 and an air outlet 22, and the oxygen inlet pipe 3 passes through the air inlet 21 and is placed in the humidifying box 2; it should be understood that the humidifying box 2 is filled with humidifying liquid for humidification, the oxygen inlet pipe 3 is just inserted into the air inlet 21 and immersed in the humidifying liquid, and the oxygen in the oxygen inlet pipe 3 flows to the air outlet 22 after passing through the humidifying liquid.

[0032] The heating tube 5 is arranged on the heating box 4, preferably arranged outside the heating box 4. The heating box 4 is respectively provided with an oxygen inlet hole 41 and an oxygen outlet hole 42, one end of the intermediate tube 6 is arranged in the outlet hole 22, and the other end is inserted into the heating box 4 through the oxygen inlet hole 41 and then passes through the oxygen outlet hole 42; it should be understood that the heating box 4 is filled with a heating liquid, and the heating tube 5 heats the heating box 4 to heat the heating liquid, thereby achieving water bath heating and heat preservation of the intermediate tube 6, and the intermediate tube 6 is just inserted into the outlet hole 22, so that the oxygen passing through the humidifying liquid flows into the intermediate tube 6.

[0033] The clamping mechanism 7 is movably mounted on the heating box 4 and can clamp the intermediate tube 6. The driving mechanism 8 is rotatably mounted on the heating box 4 and can unidirectionally drive the clamping mechanism 7 to move up and down. That is, only the rotation of the driving mechanism 8 can drive the clamping mechanism 7 to move up and down. When the driving mechanism 8 remains stationary, the height position of the clamping mechanism 7 also remains fixed. The portion of the intermediate tube 6 located in the heating box 4 is clamped by the clamping mechanism 7.

[0034] In the present application, oxygen is transported to the humidification box 2 through the oxygen inlet pipe 3, and oxygen escapes from the humidification liquid in the humidification box 2 and flows into the intermediate tube 6 in the outlet hole 22. The middle part of the intermediate tube 6 is heated and insulated by the water bath of the heating box 4 to achieve the effect of heating and insulating the oxygen. The part of the intermediate tube 6 located in the heating box 4 is clamped, and the amount of the part of the intermediate tube 6 extending into the heating box 4 for water bath heating can be adjusted by rotating the driving mechanism 8, thereby achieving the effect of adjusting the heating temperature.

[0035] At the same time, the driving mechanism 8 is unidirectionally driven, so that the position of the clamping mechanism 7 is fixed after the driving mechanism 8 is rotated, and there is no need to additionally fix the position of the clamping mechanism 7.

[0036] In other schemes, the driving mechanism 8 includes a worm 81 and a worm gear assembly 82; the worm 81 and the worm gear assembly 82 are respectively rotatably connected to the heating box 4, the worm 81 can drive the worm gear assembly 82 to rotate in one direction, and the worm gear assembly 82 can drive the clamping mechanism 7 to rise and fall. That is, the worm 81 can drive the worm gear assembly 82 to rotate, but the worm gear assembly 82 cannot drive the worm 81 to rotate.

[0037] In other schemes, the worm gear assembly 82 includes a fixed block 821, a rotating shaft 822, a worm gear body 823 and a gear 824; the fixed block 821 is fixed on the heating box 4, the rotating shaft 822 is rotatably connected to the fixed block 821, the worm gear body 823 and the gear 824 are coaxially fixed on the rotating shaft 822 respectively, the worm 81 can drive the worm gear body 823 to rotate in one direction, and the gear 824 can drive the clamping mechanism 7 to rise and fall.

[0038] In other schemes, the clamping mechanism 7 includes a rack 71, a fixed side component 72 and a sliding side component 73; the rack 71 is slidably arranged on the heating box 4 and meshes with the gear 824; the fixed side component 72 is fixed on the rack 71, the sliding side component 73 is slidably connected to the fixed side component 72 and has elasticity, and the intermediate tube 6 is located between the fixed side component 72 and the sliding side component 73. It should be understood that the fixed side component 72 and the sliding side component 73 can fix the intermediate tube 6. Preferably, the fixed side component 72 and the sliding side component 73 are respectively provided with two groups, so that the portion of the intermediate tube 6 located in the heating box 4 is U-shaped.

[0039] In other solutions, the fixed side component 72 includes a first clamping arc plate 721 and a connecting block 722; the connecting block 722 is fixed on the rack 71, the first clamping arc plate 721 is fixed on the connecting block 722 at one end away from the rack 71, and the sliding side component 73 is slidably connected to the connecting block 722. Specifically, the sliding side component 73 can slide toward the first clamping arc plate 721 to clamp the intermediate pipe 6.

[0040] In other embodiments, the sliding side assembly 73 includes a sliding rod 731, a second clamping arc plate 732, a spring 733 and a fixed plate 734; one end of the sliding rod 731 is slidably connected to the connecting block 722, and the other end is fixed to the second clamping arc plate 732; the sliding rod 731 is connected to the fixed plate 734 through the spring 733, and the fixed plate 734 is fixed to the connecting block 722. It should be understood that the sliding rod 731 can drive the second clamping arc plate 732 to slide toward the first clamping arc plate 721 to clamp the intermediate tube 6. Specifically, the gap between the second clamping arc plate 732 and the first clamping arc plate 721 is not enough to allow the intermediate tube 6 to escape.

[0041] In other solutions, a wedge block 9 is further fixedly provided in the heating box 4, and the sliding rod 731 can slide toward the first clamping arc plate 721 by squeezing the wedge block 9 when descending.

[0042] It should be understood that when the wedge block 9 is not provided, the elastic force of the spring 733 in the initial state drives the sliding rod 731 to slide toward the first clamping arc plate 721. When the wedge block 9 is provided, the elastic force of the spring 733 in the initial state drives the sliding rod 731 to slide away from the first clamping arc plate 721. When the sliding rod 731 descends, the wedge block 9 squeezes the sliding rod 731 so that the sliding rod 731 slides toward the first clamping arc plate 721 and clamps the intermediate tube 6. When the sliding rod 731 rises, the sliding rod 731 leaves the wedge block 9 and then drives the second clamping arc plate 732 away from the first clamping arc plate 721 by elastic force, thereby releasing the clamping of the intermediate tube 6. When the wedge block 9 is provided, the intermediate tube 6 is clamped only when sliding downward for water bath heating, and the clamping of the intermediate tube 6 can be released by moving away from the hot water after the oxygen supply is finished, so that the replacement of the intermediate tube 6 after the end is more convenient, and excessive clamping of the intermediate tube 6 is avoided.

[0043] In other embodiments, a sealing ring 23 is provided on the air inlet 21 and the air outlet 22. The oxygen inlet pipe 3 and the intermediate pipe 6 are respectively inserted into the sealing ring 23, and the oxygen inlet pipe 3 and the intermediate pipe 6 respectively squeeze the sealing ring 23 to a certain extent, so that the sides thereof are closely attached to the inner wall of the sealing ring 23.

[0044] In other embodiments, a fixing clamp ring 24 is further provided in the humidifying box 2, and the fixing clamp ring 24 clamps the oxygen inlet tube 3. It should be understood that the fixing clamp ring 24 clamps the oxygen inlet tube 3, thereby limiting the height position of the oxygen inlet tube 3 in the humidifying box 2, and preventing the oxygen inlet tube 3 from floating out of the humidifying liquid.

[0045] The humidification and heat preservation auxiliary device of the oxygen absorption tube can control the amount of water bathing of the intermediate tube by lifting and lowering, thereby controlling the oxygen temperature, thereby eliminating the need to adjust the temperature of the heating module.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
