Technical Field
[0001] The present invention relates to the technical field of heating flowing gas for medical devices, and specifically to a device for heating flowing gas. Background Technique
[0002] Medical gases refer to the gases used in the medical process, which are the lifeline of hospital medical services and an important support for saving lives and healing the wounded. Medical gases mainly include oxygen, nitrogen, carbon dioxide, nitrous oxide, compressed air, vacuum negative pressure suction, etc., and are mainly used in operating rooms, intensive care units, general wards, hyperbaric oxygen chambers, etc., playing an important role in the medical process. For example, medical oxygen can be used to relieve the hypoxia symptoms of patients; medical carbon dioxide gas can be used for laparoscopic abdominal insufflation and local cryoapplication; medical nitrous oxide can be used for surgical anesthesia to relieve the pain of patients, etc. During the use of medical gases, in order to ensure that the gases can play their roles better, it is necessary to heat the medical gases to a certain temperature. The existing devices for heating flowing gas have the following problems:
[0003] 1. There is no mechanism for detecting the temperature after the gas is heated, so it is impossible to ensure whether the temperature of the heated gas reaches the expected temperature. At the same time, when the gas enters the heating device, only a single channel is provided, causing the gas to flow out before being fully heated, and only the surface gas is heated, resulting in uneven heating of the gas and thus affecting the role played by the medical gas after heating.
[0004] Therefore, we propose a device for heating flowing gas to solve the problems raised above. Summary of the Invention
[0005] The purpose of the present invention is to provide a device for heating flowing gas to solve the problem in the above background technique that the existing devices for heating flowing gas on the current market do not have a mechanism for detecting the temperature after the gas is heated, so it is impossible to ensure whether the temperature of the heated gas reaches the expected temperature. At the same time, when the gas enters the heating device, only a single channel is provided, causing the gas to flow out before being fully heated, and only the surface gas is heated, resulting in uneven heating of the gas and thus affecting the role played by the medical gas after heating.
[0006] To achieve the above purpose, the present invention provides the following technical solution: A device for heating flowing gas, including an outer shell, an installation groove, a heating cavity, a heating sheet and a pressing plate. An air path connector and a data connector are installed below the outer shell, and the data connector is located on the right side of the air path connector. An installation groove is provided on the front surface of the outer shell, a heating cavity is installed above the installation groove, a heating sheet is installed above the heating cavity, a pressing plate is provided above the heating sheet, the pressing plate is designed in a ring structure, and a panel is provided above the pressing plate.
[0007] Preferably, the diameter of the installation groove is larger than that of the heating cavity, and the installation groove and the heating cavity form a snap-fit structure.
[0008] With the above structural design, it is convenient to install and fix the heating cavity inside the outer shell through the installation groove, and it is also convenient for the disassembly and assembly between the heating cavity and the outer shell, making the use more convenient.
[0009] Preferably, the heating cavity includes a cavity flow channel and air flow holes. The cavity flow channel is arranged on the upper surface of the heating cavity, and air flow holes are arranged inside the cavity flow channel. The cavity flow channel is designed in a ring structure, and the number of air flow holes is set to 4.
[0010] With the above structural design, when the medical gas flows into the inside of the outer shell and reaches the heating cavity, it flows along the labyrinthine cavity flow channel on the heating cavity, changing the flow direction of the gas and reducing the flow speed of the gas. Therefore, when the heat on the heating cavity heats the gas, the gas is heated more fully and evenly, and after heating, it flows out along the air flow holes.
[0011] Preferably, the diameter of the heating sheet is smaller than that of the heating cavity, and the heating cavity and the heating sheet form a snap-fit structure.
[0012] With the above structural design, the heating sheet plays a role in heating the heating cavity. The tight snap-fit between the heating cavity and the heating sheet can make the heating of the heating cavity by the heating sheet more sufficient, and the heat in the heating cavity is not easy to lose, thereby improving the heating efficiency of the heating sheet.
[0013] Preferably, a card slot is arranged on the front surface of the outer shell, and the card slot and the panel form a snap-fit structure.
[0014] With the above structural design, by aligning the panel with the card slot on the outer shell and pressing it, the installation of the panel can be completed, thereby playing a protective role for the parts inside the outer shell.
[0015] Preferably, a temperature measuring sensor is arranged on the left side of the outer shell, and the temperature measuring sensor is communicated with the air flow holes of the outer shell.
[0016] With the above structural design, the heated gas is finally discharged from the air flow holes of the outer shell and is measured by the temperature measuring sensor. If the temperature of the gas is higher or lower than the set temperature, the temperature (power) of the heating sheet can be adjusted down or up accordingly according to the data feedback, so as to maintain the gas temperature at the set temperature.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This heating flowing gas device:
[0018] 1. An installation groove is provided, which facilitates the installation and fixation of the heating cavity inside the outer shell through the installation groove, and also facilitates the disassembly and assembly between the heating cavity and the outer shell, making it more convenient to use;
[0019] 2. A heating cavity, a cavity flow channel and air flow holes are provided. When the medical gas flows into the interior of the outer shell and reaches the heating cavity, it flows along the labyrinth-like cavity flow channel on the heating cavity, changing the gas flow direction and reducing the gas flow speed. Thus, when the heat on the heating cavity heats the gas, the gas is heated more fully and evenly, and then flows out along the air flow holes after heating;
[0020] 3. A heating sheet is provided, and the heating sheet plays a role in heating the heating cavity. The tight clamping connection between the heating cavity and the heating sheet can make the heating of the heating cavity by the heating sheet more sufficient, and prevent the heat in the heating cavity from being easily lost, thereby improving the heating efficiency of the heating sheet;
[0021] 4. A temperature measuring sensor is provided. The heated gas finally discharges from the air flow holes of the outer shell and is measured by the temperature measuring sensor. If the gas temperature is higher or lower than the set temperature, the temperature (power) of the heating sheet can be adjusted down or up accordingly according to the data feedback, so as to maintain the gas temperature at the set temperature.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figure 1-7 , the present invention provides a technical solution: a heating flowing gas device, including an outer housing 1, a gas path joint 2, a data joint 3, a mounting groove 4, a heating cavity 5, a cavity flow channel 501, air flow holes 502, a heating sheet 6, a pressing plate 7, a card slot 8, a panel 9 and a temperature measuring sensor 10. The gas path joint 2 and the data joint 3 are installed below the outer housing 1, and the data joint 3 is located on the right side of the gas path joint 2. A mounting groove 4 is provided on the front surface of the outer housing 1, and a heating cavity 5 is installed above the mounting groove 4. The diameter of the mounting groove 4 is larger than the diameter of the heating cavity 5, and the mounting groove 4 and the heating cavity 5 form a snap-fit structure, which facilitates the installation and fixation of the heating cavity 5 inside the outer housing 1 through the mounting groove 4, and also facilitates the disassembly and assembly between the heating cavity 5 and the outer housing 1, making it more convenient to use. The heating cavity 5 includes a cavity flow channel 501 and air flow holes 502. The cavity flow channel 501 is provided on the upper surface of the heating cavity 5, and air flow holes 502 are provided inside the cavity flow channel 501. And the cavity flow channel 501 is designed in a ring structure, and the number of air flow holes 502 is set to 4. When the medical gas flows into the inside of the outer housing 1 and reaches the heating cavity 5, it flows along the labyrinthine cavity flow channel 501 on the heating cavity 5, changing the flow direction of the gas and reducing the flow speed of the gas. Thus, when the heat on the heating cavity 5 heats the gas, the gas is heated more fully and evenly, and then flows out along the air flow holes 502 after heating.
[0032] Above the heating cavity 5, a heating sheet 6 is installed. The diameter of the heating sheet 6 is smaller than that of the heating cavity 5, and the heating cavity 5 and the heating sheet 6 form a snap-fit structure. The heating sheet 6 heats the heating cavity 5. The tight snap-fit between the heating cavity 5 and the heating sheet 6 can make the heating of the heating cavity 5 by the heating sheet 6 more sufficient and prevent the heat in the heating cavity 5 from being easily lost, thereby improving the heating efficiency of the heating sheet 6. Above the heating sheet 6, a pressing plate 7 is provided, and the pressing plate 7 is designed in an annular structure. Above the pressing plate 7, a panel 9 is provided. On the front surface of the outer shell 1, a card slot 8 is provided, and the card slot 8 and the panel 9 form a snap-fit structure. Align the panel 9 with the card slot 8 on the outer shell 1 and press it to complete the installation of the panel 9, thereby protecting the parts inside the outer shell 1. On the left side of the outer shell 1, a temperature measuring sensor 10 is provided, and the temperature measuring sensor 10 is connected to the air flow hole of the outer shell 1. The heated gas finally exits through the air flow hole of the outer shell 1 and is measured by the temperature measuring sensor 10. If the temperature of the gas is higher or lower than the set temperature, the temperature (power) of the heating sheet can be adjusted down or up accordingly according to the data feedback, so as to maintain the gas temperature at the set temperature.
[0033] Working principle: When using this heating device for flowing gas, first, install all components inside the outer shell 1 and check for any abnormalities. After it is normal, power on the heating sheet 6 for heating. After being powered on, the temperature of the heating sheet 6 rises, driving the temperature inside the heating cavity 5 to rise accordingly. Then, introduce the gas through the gas path connector 2 and let it flow through the flow channel of the outer shell 1, and then reach the cavity flow channel 501 of the heating cavity 5, so that the medical gas flows along the labyrinth-like cavity flow channel 501 on the heating cavity 5. The cavity flow channel 501 changes the flow direction of the gas and reduces the flow velocity of the gas, so that when the heat on the heating cavity 5 heats the gas, the gas is heated more sufficiently and evenly. After heating is completed, it flows out along the air flow hole 502 and finally exits through the air flow hole of the outer shell 1 and is measured by the temperature measuring sensor 10. If the temperature of the gas is higher or lower than the set temperature, the temperature (power) of the heating sheet can be adjusted down or up accordingly according to the data feedback, so as to maintain the gas temperature at the set temperature. Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
