Description

Technical Field

[0001] The utility model relates to the technical field of oxygen supply devices, in particular to a constant temperature oxygen supply device. Background Art

[0002] An oxygen supply device is a dedicated respiratory support system that is set up to ensure that patients have adequate oxygen supply when they have difficulty breathing. The function of an oxygen supply device is to deliver filtered air or high-purity oxygen directly to the patient through a pipeline to meet the body's demand for oxygen.

[0003] After part of the oxygen in the oxygen cylinder is used up, the mass of the remaining oxygen decreases, while the mass of the gas decreases and the volume remains unchanged. The density formula shows that the density of the oxygen in the bottle decreases. At the same time, thermal expansion and contraction show that when the volume of the gas remains unchanged, the gas expands due to heat, causing the temperature to rise, which can easily lead to inconsistent temperatures at the beginning and end of oxygen supply, affecting the patient's comfort.

[0004] Therefore, those skilled in the art provide a constant temperature oxygen supply device to solve the problems raised in the above background technology. Utility Model Content

[0018] Beneficial effects of the utility model:

[0019] The utility model is provided with a heating coil, a first solenoid valve, a second solenoid valve, a U-shaped insulation pipe and a heating pipe. When in use, the oxygen supply machine draws the oxygen in the oxygen concentrator into the connecting pipe. At this time, when the second temperature sensor detects that the oxygen temperature is within a set range, the valve is closed and the second solenoid valve is opened, and the oxygen is directly discharged through the U-shaped insulation pipe. When the temperature is lower than the set range, the second solenoid valve is closed and the valve is opened. At the same time, the heating pipe efficiently heats the oxygen through a plurality of staggered and spaced heating rods, and then the first temperature sensor detects the oxygen temperature.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please see attached Figure 1-4 A constant temperature oxygen supply device in an embodiment of the utility model comprises a shell 1, an oxygen concentrator 13 is placed inside the shell 1, an oxygen concentrator 13 is fixedly connected to the top of the oxygen concentrator 13, a connecting pipe 5 is fixed to the output end of the oxygen concentrator 9, a heating pipe 8 can be assembled and connected below the connecting pipe 5, and the assembled connection can be detachable, a flange 17 is arranged between the upper and lower ends of the heating pipe 8 and the connecting pipe 5, a sealing ring 19 is fixed on one side of the flange 17, and the sealing ring 19 can enhance the tightness of the connection to prevent oxygen leakage, and when the heating pipe 8 is damaged and needs to be repaired, the flange 17 can be removed, wherein the flange 17 is connected by bolts, so that the heating pipe 8 can be repaired or replaced in time;

[0029] The heating tube 8 is fixed with staggered and spaced heating rods 18. The heating rods 18 are spaced to extend the heating range. If one heating rod 18 is damaged, it will not affect the next heating. The staggered arrangement facilitates a larger area to contact with oxygen, making the heating more sufficient and efficient, thereby ensuring the heating efficiency.

[0030] A heating coil 11 is fixed inside the connecting pipe 5 above the heating pipe 8. The heating coil 11 is composed of a heating wire. A first solenoid valve 6 is fixed above the heating coil 11. A valve 21 is fixed below the heating coil 11.

[0031] One side of the connecting pipe 5 is connected to a U-shaped insulation pipe 10, the input end of the U-shaped insulation pipe 10 is connected below the valve 21, the output end of the U-shaped insulation pipe 10 is connected above the first solenoid valve 6, and the output end and input end of the U-shaped insulation pipe 10 are fixedly connected to the second solenoid valve 12.

When in use, the required temperature range is set by the controller 3, and the oxygen supply machine 9 sucks the oxygen in the oxygen generator 13 into the connecting pipe 5. At this time, when the second temperature sensor 20 detects that the oxygen temperature is within the set range, the valve 21 is closed and the second solenoid valve 12 is opened, and the oxygen is directly discharged through the U-shaped insulation pipe 10. When the temperature is lower than the set range, the second solenoid valve 12 is closed and the valve 21 is opened, and the heating pipe 8 heats the oxygen through a plurality of staggered and spaced heating rods 18. The oxygen is effectively heated, and then the first temperature sensor 7 detects the oxygen temperature.

At the same time, the oxygen can be heated again under the action of the residual heat in the heating coil 11 and the connecting pipe 5 (wherein, since the heating pipe 8 is connected to the connecting pipe 5, the residual heat in the connecting pipe 5 comes from the heating pipe 8 and the heating rod 18), so that it reaches the set temperature range and is discharged to the oxygen breathing mask 4, effectively ensuring that the temperature difference between the initial and later stages of oxygen supply is maintained within a certain range, thereby enhancing the user's comfort. When the second temperature sensor 20 detects that the oxygen temperature at the output of the oxygen supply machine 9 has reached the set temperature, the heating rod 18 stops heating, and the oxygen can be directly delivered, further improving the stability of the oxygen delivery temperature and achieving efficient operation.

The storage area 14 is used to place an oxygen generator 13, wherein the oxygen generator 13 is not limited to oxygen production, but also has the function of storing oxygen. A plurality of self-locking universal wheels 15 are rotatably connected to the bottom of the shell 1, which is convenient for moving the shell 1. The switch door 2 facilitates the inspection and maintenance of the inside of the shell 1, and also facilitates the replacement of the oxygen generator 13, which is convenient to use.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
