[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1 、 Figure 2 As shown, the present invention provides an end-tidal carbon dioxide probe with a heat insulation device, including an end-tidal carbon dioxide monitor 1 and a trachea 2. The trachea 2 is located on the left side of the end-tidal carbon dioxide monitor 1. A probe body 3 is provided at the input end of the trachea 2. The probe body 3 includes an end-tidal carbon dioxide probe 31. The end-tidal carbon dioxide probe 31 is fixedly connected to the input end of the trachea 2. The outer wall of the end-tidal carbon dioxide probe 31 is sleeved with a heat insulation mechanism 32. A plurality of air inlet holes 33 are provided in a circular array on the left outer wall of the end-tidal carbon dioxide probe 31. A limit plate 35 is fixedly installed on the rightmost side of the outer wall of the end-tidal carbon dioxide probe 31. A positioning clamp 36 is fixedly installed on the left side of the limit plate 35. A non-toxic medical silicone sleeve 34 is fixedly installed on the outer wall of the heat insulation mechanism 32. The annular gap between the right side of the outer wall of the heat insulation mechanism 32 and the right side of the inner ring of the non-toxic medical silicone sleeve 34 is clamped with the positioning clamp 36.
[0021] When using the end-tidal carbon dioxide probe 31, the heat insulating mechanism 32 is directly put on the outer wall of the end-tidal carbon dioxide probe 31, and is moved and pressed toward the limit plate 35 until the end where the air inlet 33 is located moves out of the left side of the heat insulating mechanism 32. At the same time, the heat insulating mechanism 32 is fixed to the positioning clamp 36 on the left side of the limit plate 35 by using the gap with the non-toxic medical silicone sleeve 34. Then the entire heat insulating mechanism 32 and the end-tidal carbon dioxide probe 31 can be placed in the patient's trachea. The use of the non-toxic medical silicone sleeve 34 can avoid harm to the human body. At the same time, the left end of the heat insulating mechanism 32 and the non-toxic medical silicone sleeve 34 is designed with an inclined arc to prevent scratching the patient's trachea.
[0022] like Figure 3 As shown, the heat insulation mechanism 32 includes two heat insulation inner rings 321, a silicone damping ring 322 is fixedly installed between the opposite ends of the two heat insulation inner rings 321, a plurality of damping protrusions 323 are fixedly installed in an annular array on the inner ring of the silicone damping ring 322, and a heat insulation outer ring sleeve 324 is fixedly installed on the outer wall of the two heat insulation inner rings 321, and the outer wall of the heat insulation outer ring sleeve 324 is fixedly connected to the inner ring of the non-toxic medical silicone sleeve 34;
[0023] The thermal insulation inner ring 321 is made of silicate insulation material, which is an inorganic insulation material made of silicate as the main raw material after high-temperature melting. It has excellent thermal insulation effect, and is non-toxic, non-radioactive, non-flammable, and resistant to acid and alkali corrosion. At the same time, it also has relatively high strength and durability and a long service life. The thermal insulation outer ring sleeve 324 is made of polyurethane foam material, which is a foam material made of polyurethane raw material with low density and low thermal conductivity. It has excellent thermal insulation effect and is fluorine-free, non-toxic, odorless, and does not release harmful substances. When the end-tidal carbon dioxide probe 31 uses the internal sensor module for detection, the emitted temperature is well blocked by the thermal insulation inner ring 321 and the thermal insulation outer ring sleeve 324, thereby avoiding long-term heat damage to the patient's trachea. At the same time, when the thermal insulation inner ring 321 is sleeved on the outer wall of the end-tidal carbon dioxide probe 31, the friction is increased by the several damping bumps 323 on the inner ring of the silicone damping ring 322, making it more firmly fixed.
[0024] like Figure 4 、 Figure 5As shown, a threaded head 11 is fixedly installed on the left input end of the end-tidal carbon dioxide monitor 1, and a threaded mounting ring 21 is fixedly connected to the output end of the trachea 2. The threaded mounting ring 21 is threadedly connected to the threaded head 11. A positioning mechanism 12 is fixedly installed on the left side of the end-tidal carbon dioxide monitor 1. The positioning mechanism 12 is located on the rear side of the threaded head 11. The positioning mechanism 12 includes two fixing rods 121. The left ends of the two fixing rods 121 are movably mounted with mirror-image arc-shaped clamping plates 122. Three clamping springs 123 are fixedly connected between the opposite ends of the two arc-shaped clamping plates 122. Rubber pads 124 are fixedly installed on one side of the opposite surfaces of the two arc-shaped clamping plates 122. The rubber pads 124 can increase the friction resistance when the arc-shaped clamping plates 122 are clamped, thereby improving the clamping stability.
[0025] When the monitoring is completed, the threaded mounting ring 21 and the threaded head 11 at one end of the trachea 2 can be rotated and disassembled, and the overall insulation mechanism 32 can be unplugged from the end-tidal carbon dioxide probe 31, and then thorough heat dissipation and cleaning and disinfection can be carried out. Then the insulation mechanism 32 can be re-sleeved on the outer wall of the end-tidal carbon dioxide probe 31. At the same time, when the end-tidal carbon dioxide probe 31 is not in use temporarily, the insulation mechanism 32 can be directly inserted between the two arc-shaped splints 122 using the non-toxic medical silicone sleeve 34 on the outer wall, so that the two arc-shaped splints 122 can be rotated to both sides using the movable connection between the two fixed rods 121, and the clamping spring 123 between the opposite ends is squeezed. Under the elastic action of the clamping spring 123, the two arc-shaped splints 122 use the rubber pad 124 to clamp and fix the insulation mechanism 32.
[0026] The following is a detailed description of the working principle of the end-tidal carbon dioxide probe with a heat insulation device.
[0027] like Figure 1-5As shown, when using the end-tidal CO2 probe 31, the insulation mechanism 32 is directly put on the outer wall of the end-tidal CO2 probe 31, and is moved and pressed toward the limit plate 35 until the end where the air inlet 33 is located moves out of the left side of the insulation mechanism 32. At the same time, the insulation mechanism 32 is clamped into the positioning clamp ring 36 on the left side of the limit plate 35 by using the gap with the non-toxic medical silicone sleeve 34 to complete the fixation. Then the entire insulation mechanism 32 and the end-tidal CO2 probe 31 can be placed in the patient's trachea, and the non-toxic medical silicone sleeve 34 can be used to avoid harm to the human body. At the same time, the left end entry direction of the insulation mechanism 32 and the non-toxic medical silicone sleeve 34 is designed with an inclined arc to prevent scratching the patient's trachea. When the end-tidal CO2 probe 31 uses the internal sensor module to perform detection work, the emitted temperature is well blocked by the insulation inner ring 321 and the insulation outer ring sleeve 324, thereby avoiding long-term heat damage to the patient's trachea. When the end-tidal CO2 probe 31 is in use, the outer wall of the end-tidal CO2 probe 31 is fixed with several damping protrusions 323 on the inner ring of the silicone damping ring 322 to increase the friction force and make it more firmly fixed. When the monitoring is completed, the threaded mounting ring 21 at one end of the trachea 2 and the threaded head 11 can be rotated and disassembled, and the overall heat insulation mechanism 32 can be pulled off the end-tidal CO2 probe 31 to carry out thorough heat dissipation and cleaning and disinfection. Then the heat insulation mechanism 32 can be re-sleeved on the outer wall of the end-tidal CO2 probe 31. At the same time, when the end-tidal CO2 probe 31 is not in use temporarily, the heat insulation mechanism 32 can be directly clamped between the two arc-shaped splints 122 using the non-toxic medical silicone sleeve 34 on the outer wall, so that the two arc-shaped splints 122 can be rotated to both sides using the movable connection between the two fixing rods 121, and the clamping spring 123 between the opposite ends is squeezed. Under the elastic action of the clamping spring 123, the two arc-shaped splints 122 use the rubber pad 124 to clamp and fix the heat insulation mechanism 32.
[0028] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
