We can measure end-tidal carbon dioxide to reflect various changes in patients' ventilation, circulation, metabolism, etc.

[0003] It is found through research that the existing oxygen inhalation tubes have the following deficiencies: Since the existing products only have the functions of collecting end-tidal carbon dioxide from one nostril and inhaling oxygen from one nostril, there are problems of insufficient collection of end-tidal carbon dioxide and insufficient oxygen inhalation, which may affect the monitoring of patients' vital signs and the treatment effect.

[0009] Preferably, the cross-section of the oxygen inhalation cylinder is trapezoidal, and the cylinder body, the partition board and the top plate are made of soft silica gel.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3 , a silica gel type end-tidal carbon dioxide collection oxygen inhalation tube, which includes an oxygen inhalation mask 1. An oxygen flow cavity 2 is opened inside the oxygen inhalation mask 1. A through cavity 3 is opened below the oxygen flow cavity 2 inside the oxygen inhalation mask 1. An air inlet 4 communicating with the through cavity 3 is opened on one side of the oxygen inhalation mask 1 where the oxygen flow cavity 2 is located. Adaptation grooves 5 are opened on both sides of the air inlet 4 on the surface of the oxygen inhalation mask 1. The adaptation groove 5 includes an upper lip groove 51 and a lower lip groove 52. The upper lip groove 51 is the placement position for the upper lip, and the lower lip groove 52 is the placement position for the lower lip. One side of the oxygen inhalation mask 1 is fixedly installed with an oxygen supply tube 6, and the oxygen supply tube 6 is communicated with the oxygen flow cavity 2. The other side of the oxygen inhalation mask 1 is fixedly installed with a circulation tube 7, and the circulation tube 7 is communicated with the inside of the through cavity 3. Oxygen inhalation cylinders 8 are symmetrically and fixedly installed on the top of the oxygen inhalation mask 1.

[0020] Please refer to Figures 1 - 4 , the oxygen inhalation cylinder 8 includes a cylinder body 81. A partition plate 82 is fixedly installed inside the cylinder body 81. An A cavity 83 is opened on one side of the partition plate 82 inside the cylinder body 81. A B cavity 84 is opened on the other side of the partition plate 82 inside the cylinder body 81. The top diameter of the B cavity 84 is smaller than the top diameter of the A cavity 83. Below the opening at the top of the B cavity 84, there is a top plate 85. A coil spring 86 is movably connected between the top plate 85 and the partition plate 82. The end of the oxygen inhalation cylinder 8 away from the oxygen inhalation mask 1 has a larger diameter than the end of the oxygen inhalation cylinder 8 close to the oxygen inhalation mask 1. The diameter of the end of the cylinder body 81 away from the oxygen inhalation mask 1 is larger than the diameter of the nostril opening. The A cavity 83 is communicated with the inside of the oxygen flow cavity 2, and the B cavity 84 is communicated with the inside of the through cavity 3;

[0021] The cylinder body 81, the partition plate 82 and the top plate 85 are made of soft silica gel. The cross-section of the oxygen inhalation cylinder 8 is trapezoidal and can be pressed. By using fingers to pinch the oxygen inhalation cylinder 8, the oxygen inhalation cylinder 8 can be deformed. After the deformed oxygen inhalation cylinder 8 is inserted into the nostril, the oxygen inhalation cylinder 8 returns to its original shape and is clamped into the nostril. Without the influence of external forces, the oxygen inhalation cylinder 8 is firmly clamped in the nostril.

[0022] Please refer to Figures 1 - 4, after inserting the oxygen inhalation cylinder 8 into the nostrils, place the entire device on the lips, with the upper lip positioned at the upper lip groove 51 and the lower lip positioned at the lower lip groove 52. Align the air inlet 4 with the middle of the mouth. Connect the oxygen supply tube 6 to the oxygen source. The oxygen passes through the oxygen flow cavity 2 and the A cavity 83 and enters the user's nasal cavity, enabling the user to inhale gas with a relatively high oxygen content. Since the spiral spring 86 presses the top plate 85 against the opening of the B cavity 84, the user will not inhale gas from the inside of the B cavity 84 but only inhale the gas inside the A cavity 83. After the user exchanges gas in the body, the gas with a relatively high oxygen content is converted into gas with a relatively high carbon dioxide content. The carbon dioxide gas exhaled through the mouth enters the through cavity 3 through the air inlet 4. Connect the end of the circulation tube 7 to a carbon dioxide detection device to detect the carbon dioxide content in the exhaled gas of the user. However, a small portion of the exhaled gas is exhaled from the nasal cavity, and the exhaled gas is sufficient to push open the top plate 85 at the opening of the B cavity 84, allowing the exhaled gas to flow into the inside of the through cavity 3 through the B cavity 84, and then detecting the carbon dioxide content therein through the carbon dioxide detection device.

[0023] Working principle: Squeeze the oxygen inhalation cylinder 8 with your fingers, which can cause the oxygen inhalation cylinder 8 to deform. Insert the deformed oxygen inhalation cylinder 8 into the nostrils. After the oxygen inhalation cylinder 8 enters the nostrils, it returns to its original shape and is stuck in the nostrils. Without the influence of external forces, the oxygen inhalation cylinder 8 is firmly stuck in the nostrils. After inserting the oxygen inhalation cylinder 8 into the nostrils, place the entire device on the lips, with the upper lip positioned at the upper lip groove 51 and the lower lip positioned at the lower lip groove 52. Align the air inlet 4 with the middle of the mouth. Connect the oxygen supply tube 6 to the oxygen source. The oxygen passes through the oxygen flow cavity 2 and the A cavity 83 and enters the user's nasal cavity, enabling the user to inhale gas with a relatively high oxygen content. Since the spiral spring 86 presses the top plate 85 against the opening of the B cavity 84, the user will not inhale gas from the inside of the B cavity 84 but only inhale the gas inside the A cavity 83. After the user exchanges gas in the body, the gas with a relatively high oxygen content is converted into gas with a relatively high carbon dioxide content. The carbon dioxide gas exhaled through the mouth enters the through cavity 3 through the air inlet 4. Connect the end of the circulation tube 7 to a carbon dioxide detection device to detect the carbon dioxide content in the exhaled gas of the user. However, a small portion of the exhaled gas is exhaled from the nasal cavity, and the exhaled gas is sufficient to push open the top plate 85 at the opening of the B cavity 84, allowing the exhaled gas to flow into the inside of the through cavity 3 through the B cavity 84, and then detecting the carbon dioxide content therein through the carbon dioxide detection device.
