Detailed Description
The invention is described in further detail below with reference to the following figures and specific embodiments:
the invention discloses a posterior naris oxygen inhalation tube, which is used for medical posterior naris oxygen therapy. The oxygen tube is a special instrument and is specially suitable for the postnasal oxygen delivery of a patient.
As shown in fig. 1 and 2, the posterior nostril oxygen inhalation tube comprises an oxygen therapy tube 1 which is inserted into the nasal cavity. The outer end of the oxygen therapy tube 1 is communicated with the oxygen therapy machine, and the inner end of the oxygen therapy tube extends into the nasal cavity and is positioned at the rear nostril. The end of the oxygen therapy tube 1 communicated with the oxygen therapy machine is open, and the end inserted into the nasal cavity is closed. The closed end of the oxygen catheter 1 is provided with an arc-shaped guide head 2, and the side wall of the arc-shaped guide head 2 is provided with an air delivery hole 3. Oxygen is delivered into the trachea through the air delivery hole 3, and oxygen airflow cannot directly blow to the inner side wall of the nasal cavity, so that uncomfortable feeling is avoided.
In a specific implementation, as shown in fig. 2, an air delivery head 8 is also disposed at the air delivery hole 3, and the oxygen flow can be blown out obliquely through the air delivery head 8. Specifically, the angle between the gas transmission head 8 and the oxygen transmission tube 1 is set to be 90-125 degrees. When the oxygen catheter 1 is inserted into the nasal cavity with the innermost end at the posterior nares, as shown in fig. 3, the head 8 can be oriented just towards the trachea, so that the oxygen flow can be better introduced into the trachea.
In a specific implementation, the length of the gas transmission head 8 is 0.4-0.8 cm. The length of the gas transmission head 8 is not suitable to be too long, and if the length is too long, the insertion of the oxygen transmission tube is influenced.
The air delivery holes 3 of the back nostril oxygen delivery tube are arranged in another way, specifically, a plurality of air delivery holes 3 are intensively arranged on the side wall of the arc-shaped guide head 2 part of the oxygen delivery tube 1 to form an air delivery hole area, the diameter of the air delivery holes under the structure is smaller than that when only one air delivery hole is arranged, as shown in figure 4, the air delivery hole area is positioned on one side of the oxygen delivery tube, the air delivery holes in the air delivery hole area are arranged in a circular array, the air delivery holes 3 under the structure can ensure more uniform output of oxygen, the oxygen is blown into the trachea in a plurality of small airflow forms, and the discomfort caused by the impact on the trachea in the airflow state can be avoided.
The middle part of the oxygen therapy tube 1 is provided with the balloon 4, and the balloon 4 can be enlarged after being inflated, so that the balloon can be clamped at the inner side of the front nostril outlet, namely in the nasal cavity. The side surface of the balloon 4 facing the arc-shaped guide head 2 is provided with a plurality of vent holes 5, so that part of gas in the balloon 4 can flow out. Correspondingly, a gas transmission sleeve 6 is communicated with one side of the balloon 4 without the vent hole 5, and the balloon 4 is ventilated through the gas transmission sleeve 6. Because the diameter of the air delivery hole is small (generally 1-2 mm), the inlet flow of the air delivery sleeve 6 is larger than the outlet flow of the vent hole 5, and the balloon 4 can be in an expansion state. The gas transmission sleeve 6 is sleeved on the outer side of the oxygen transmission tube 1, and the space between the gas transmission sleeve 6 and the oxygen transmission tube 1 can transmit gas into the saccule 4. The end part of the outermost end of the gas transmission sleeve 6 is closed, a gas transmission interface 7 is arranged on the side surface of the outer end of the gas transmission sleeve 6, and the gas transmission interface 7 can also be communicated with an oxygen therapy machine or connected with other instruments such as an atomizer and the like. Nebulized medicament or humidified oxygen can be delivered via the gas delivery interface 7. 4 cards of sacculus when this oxygen tube sets up are in the nasal cavity, reduce for the card uncomfortable sense at trachea entrance, and this sacculus 4 is provided with air vent 5 can be towards the intracavitary input oxygen of nose especially input humidifying oxygen, can guarantee the moist of nasal cavity, have the guard action to the nasal cavity mucous membrane. Meanwhile, due to the arrangement of the vent holes 5 on the balloon 4, the gas in the balloon 4 is always in an outward discharge state, so that the balloon 4 is not in a maximum expansion state, the balloon 4 is in a more proper expansion state, the oxygen catheter 1 can not slide from the nasal cavity, and the uncomfortable feeling of the nasal cavity caused by over expansion of the balloon 4 is avoided. The balloon 4 is inflated by using the gas transmission sleeve 6, so that the gas entering the balloon 4 through the gas transmission sleeve 6 enters from the periphery, the inflation in the balloon 4 is uniform, the shape consistency of the inflated balloon 4 is good, and the balloon is less prone to falling compared with a single catheter type direct inflation mode.
In the processing and manufacturing of the posterior nostril oxygen catheter, the distance between the balloon 4 and the arc-shaped guide head 2 can be set into a plurality of models, and the suitable model is selected according to the actual requirement of a patient in use.
The oxygen tube is further improved in that scales are arranged on the surface of the oxygen tube 1, so that the length of the oxygen tube 1 inserted into the nasal cavity can be prompted, and a doctor can conveniently judge whether the oxygen tube 1 is inserted into the position of a posterior nostril or not.
The oxygen tube needs to ensure that the air transmission hole 3 or the air transmission head 8 at one end of the arc-shaped guide head 2 of the oxygen tube 1 faces the trachea when in use, and in order to facilitate the operation of a doctor, the other end of the oxygen tube 1 opposite to the arc-shaped guide head 2 is provided with a mark for distinguishing the direction of the air transmission hole 3. For example, a break or a marking may be provided as a marking. The marks may be arranged on the same side or on opposite sides of the gas transfer port 3, the opening of the gas transfer port 3 being oriented according to the marks.
In the specific implementation of the invention, in order to facilitate the connection of the oxygen therapy pipe 1 and the joint, a flaring 9 is arranged at one end of the oxygen therapy pipe 1 with a mark. The flaring 9 can be quickly and accurately inserted into the joint.
In the specific implementation of the invention, the outward flanging is arranged at the outlet of the air delivery head 8, and the friction between the lowest end part of the air delivery head 8 and the inner wall of the nasal cavity can be reduced as much as possible by the outward flanging, so that the uncomfortable feeling during intubation can be reduced.
The oxygen tube in fig. 1, 2 and 4 is in a straight line state to show the structure and relative position relationship of each part more clearly, and in actual use, the oxygen tube and the oxygen cannula are both flexible tubes and can bend with the shadow.
The back nostril oxygen tube can be used when being used as a bronchoscope, and is particularly suitable for children bronchoscope patients.
The invention designs the posterior naris oxygen inhalation tube with a brand new structure according to the use requirements of medical staff and the use experience of patients, and the oxygen inhalation tube is particularly suitable for the oxygen delivery of the posterior naris. The oxygen tube has reasonable structure and convenient operation and use. The oxygen inhalation tube can promote the implementation of oxygen inhalation of the posterior naris, thereby improving the utilization rate of oxygen; the back nostril oxygen inhalation tube ensures that medical workers and patients have good use experience.
