Detailed Description
The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.
Example (b):
for solving the patient when using nasal cavity oxygen tube for a long time, the stimulation that oxygen surge pressure caused nasal cavity mucosa, this embodiment has proposed a comfortable type nasal cavity oxygen tube, and this nasal cavity oxygen tube is distinguished from current device that improves the nasal cavity comfort level through increasing oxygen humidity or temperature, has proposed one kind and can reduce the direct surge pressure of oxygen to the nasal cavity through the reposition of redundant personnel to improve the comfort level of patient's oxygen uptake.
The present embodiment adopts the oxygen inhalation tube body 2 shown in fig. 2, on which the nasal cavity catheter 1 is arranged, and the improvement point is that: the nasal catheter 1 is provided with an end face 3 for closing the end part, and as shown in fig. 3, the side wall of the nasal catheter 1 near the end face 3 is provided with a plurality of oxygen inhalation ports 4 which are uniformly distributed in the circumferential direction. When the nasal catheter is used, oxygen flows into the nasal catheter 1 along the oxygen inhalation tube body 2, and before entering the nasal cavity of a patient, the oxygen is contacted with the end face 3 and is shunted to the oxygen inhalation ports 4 on the periphery and then enters the nasal cavity of the patient, and the shunting design has the purpose of weakening and dispersing the impact force of the oxygen on the nasal mucosa, so that the comfort level of the nasal inhalation of the patient is greatly improved. In this embodiment, by controlling the size and the distance of the oxygen inhalation ports 4, not only can the oxygen supply amount be effectively ensured, but also the oxygen impact force can be controlled. During specific implementation, the oxygen inhalation ports 4 are arranged to be rectangular openings, the long sides of the rectangular openings are parallel to the end faces 3, the length is controlled to be 0.18-0.22 mm, the length of the wide sides of the rectangular openings is controlled to be 0.8-0.12 mm, and the distance between every two adjacent oxygen inhalation ports 4 is controlled to be 0.1-0.2 mm. For example, in one embodiment, rectangular openings of 0.1mm by 0.2mm are provided with a pitch of 0.15 mm. In addition, in the present embodiment, the side wall of the nasal cavity catheter 1 is further provided with a plurality of oxygen outlet holes 6, so that the impact force can be dispersed on the premise of ensuring the oxygen flow. When in use, the diameter of the oxygen outlet holes 6 is controlled to be 0.1-0.2 mm, for example, in one embodiment, the diameter of the oxygen outlet holes 6 is 0.15 mm. Certainly, in order to improve the comfort of the patient inhaling oxygen, the oxygen outlet holes 6 and the oxygen outlet holes 6 and 4 should be distributed in a staggered manner.
