Description

A self-adjusting oxygen flow nasal oxygen tube

technical field

The utility model relates to a medical device, in particular to a self-adjusting oxygen flow nasal oxygen tube.

Background technique

Nasal oxygen tube is an oxygen tube used in hospitals for patients with dyspnea and hypoxia. It inserts nasal prongs into the patient's nostrils, allowing oxygen to be drawn from the patient's nostrils into the lungs. In the process of clinical emergency first aid or daily patient treatment, it is one of the important links to use nasal oxygen tube to inhale oxygen to the patient. There are differences in the size of the nostrils of each patient, and the size of the existing nasal oxygen tube inserted into the nostril is fixed and cannot vary from person to person. This leads to the fact that the nasal oxygen tube purchased uniformly by the hospital is suitable for some patients. Other patients may be too small, so that after being inserted into the nostril, it is not only loose and easy to fall off from the nostril, but also a part of oxygen will escape from the gap between the nasal oxygen tube and the nasal cavity without being used during oxygen inhalation. In addition, the existing nasal oxygen tube lacks a flow regulating device, and it is difficult for bedridden patients to conveniently adjust the oxygen flow by themselves. These problems will reduce the utilization rate of oxygen and cause waste of materials. The utility model patent with the publication number CN207912997U disclosed a nasal oxygen tube on September 28, 2018, including a bell mouth, a main tube, a fixed tube and an earring. The end of the main tube is connected with a three-way joint, and two The branch tube, the earring includes a ring body, and the ring body is provided with a passageway. The middle part of the fixed tube is fixed with two nasal tubes for insertion into the nose. Then snap into the nasal tube so that the branch tube and the nasal tube communicate and fix the first piercing hole. The fixing tube is also provided with a second piercing hole for the branch tube to pass through. The ends of the branch tubes are sequentially passed through Through the piercing channel, the second piercing hole and the first piercing hole of the earring on the corresponding side, the branch pipe penetrates the second piercing hole from the rear side of the fixing pipe, and then pierces the first piercing hole from the front side of the fixing pipe. Holes are provided; the two ends of the fixed pipe are respectively threaded with fastening ropes, the two free ends of the fastening ropes are fixedly connected to the two ends of the corresponding side ring body respectively, and the fastening ropes are provided with rope buckles. But this utility model can only solve the problem that the nasal oxygen tube falls off, but cannot solve the problem of improving the oxygen utilization rate in the oxygen inhalation process.

Utility model content

The existing nasal oxygen tube has a fixed size and lacks a flow regulating device, which leads to the problem of low oxygen utilization rate when inhaling oxygen. In order to overcome these defects, the utility model provides a device that can reduce oxygen waste and facilitate patients to adjust the oxygen flow rate by themselves. , Self-regulating oxygen flow nasal oxygen tube to improve oxygen utilization.

The technical scheme of the utility model is: a self-adjusting oxygen flow nasal oxygen tube, including the main body of the oxygen delivery tube and a nasal cannula, the nasal cannula is connected to the main body of the oxygen delivery tube, the main body of the oxygen delivery tube is provided with a flow regulator, and the nasal cannula The port is provided with a tapered nostril plug, the nostril plug is provided with an air inlet connected with the nasal cannula, and the peripheral surface of the nostril plug is provided with an air outlet leading to the outer end surface of the nostril plug. The tapered nostril plugs have good adaptability to different sizes of nostrils. The plugs in the nostrils can eliminate the gap between the nasal cannula and the nasal cavity, so that the nasal cavity can be closed to a certain extent, which is not only conducive to the firm insertion of the nasal cannula In the nostrils, it also makes it difficult for the oxygen entering from the air intake to escape. The flow regulator can allow patients to conveniently adjust the oxygen flow by themselves to better match their own breathing rate and vital capacity. Therefore, the self-oxygenation flow nasal oxygen tube can improve the oxygen utilization rate during oxygen inhalation.

Preferably, there are 4-6 air outlet holes, which are evenly distributed in a circular shape around the nostril plug axis. The air outlet holes arranged in this way can ensure that the exhaled gas is discharged evenly and smoothly.

Preferably, the nostril plug is threadedly connected with the nasal cannula. The screw connection method is simple and reliable.

Alternatively, the nasal cannula is plugged onto the nostril plugs. The nostril plug and the nasal cannula are connected by plugging, and the structure is simple and easy to implement.

Preferably, the nasal cannula is T-shaped and there are two. The three ports of the nasal cannula are the oxygen delivery tube interface, the nasal cannula docking interface and the nasal insertion port respectively. The oxygen delivery tube interface is connected to the main body of the oxygen delivery tube. The nasal cannula docking port of the cannula is communicated through a connecting tube, and the nostril plug is connected to the nasal opening. The split-structure nasal cannula can be adjusted to better suit the nostril spacing.

The beneficial effects of the utility model are:

Improve oxygen utilization when inhaling oxygen. The nostril plug with taper in the utility model can make the nasal cavity form a certain degree of closure, so that the oxygen entering from the air intake hole is not easy to escape, and the flow regulator can be used by the patient to adjust the oxygen flow conveniently and better match their own Respiratory rate and lung capacity are conducive to improving the oxygen utilization rate during oxygen inhalation.

The nasal cannula fixation performance and ventilation performance are more balanced. The utility model is provided with an air outlet on the nostril plug, taking into account the fixing and ventilating functions of the nasal intubation, and avoiding partial use of functions.
