Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a modified 3D prints high flow nasal oxygen tube.
Background
The existing nasal oxygen tube is usually manufactured by one-step molding, and the advantage that the existing nasal oxygen tube can supply oxygen to the nasal cavity cannot be fully utilized. The double-nasal-cavity oxygen inhaler in the market at present has thinner tubes connected with a nose, air in lungs is exhaled from the periphery of a nasal adapter tube during exhalation, oxygen enters nostrils from the nasal adapter tube during inhalation, and air is inhaled from the gaps due to the gaps left between the nasal adapter tube and the nostrils, so that high-concentration oxygen is difficult to input into the nostrils; in the medical treatment process of a patient, moist oxygen can also cause stimulation to nasal mucosa of the patient, in addition, most users use the nasal oxygen cannula at night, the nasal oxygen cannula is easy to fall off once the user turns over or performs other actions, the light is dark at night, the fallen nasal oxygen cannula is not convenient to search, and therefore certain influence is caused on oxygen delivery. And because the size of every people's nose word is different, so exist current nasal oxygen tube laminating nature low, the easy slippage of patient after wearing, probably there is gas leakage in the oxygen transportation process, the inspiratory capacity reduces, the malleation effect is poor, oxygen utilization ratio reduces, can not reach effective oxygen concentration, the problem that clinical curative effect declines. Therefore, aiming at the defects of the prior art, a 3D printing high-flow nasal oxygen tube which is not easy to fall off, has high oxygen utilization rate, can provide positive pressure ventilation, can be matched with the nose of a patient and has better fitting performance is needed to be designed, so that the problems of air leakage, less inhaled oxygen, easy falling off, reduced oxygen utilization rate and the like of the existing nasal oxygen tube are solved.
Search patent documents such as publication nos.: CN206063515U discloses a medical high flow oxygen uptake nasal catheter, including the nasal catheter body, and set up the nasal suction pipe on the nasal catheter body, and set up the gasbag on the nasal catheter body, and set up fixed cover on the nasal catheter body, and set up the nasal suction pipe fixed part on the nasal catheter body, the both ends mouth position of nasal suction pipe is all fixed on nasal suction pipe fixed part, the inside cavity form setting that is of nasal suction pipe fixed part, the gasbag is fixed at nasal suction pipe lower part middle part, be equipped with two oxygen uptake heads on the gasbag, the symmetry is equipped with two inflation inlets on the nasal suction pipe, fixed cover is established on nasal suction pipe fixed part, be equipped with the connector that is used for connecting outside oxygen supply equipment on the fixed cover. This patent mainly solves the quantization of high flow oxygen tube, nose head part connection elasticity and oxygen tube at the fine fixed problem of head, but the nasal oxygen tube that this patent relates can not solve some patients and lead to current nasal oxygen tube bore to mismatch because of the bore difference of nose, and then the problem of nasal oxygen tube gas leakage in the use, patent publication number: CN201543068U discloses a two nasal cavities of high concentration oxygen inhalers, the utility model discloses a nose is taken over, oxygen therapy pipe and flow control valve, and the nose is taken over and has two, and two noses are taken over and are connected with oxygen therapy pipe respectively, and flow control valve establishes on oxygen therapy pipe, the nose take over including body, baffle, flap and dog, the outer wall and the sealed cooperation of nostril of body, the baffle is fixed in the body, has two to separate into the semicylinder cavity by the baffle in the body, the flap is the semicircle plate body that radius and body internal diameter equal, the flap setting is in a semicylinder cavity of body, the lower extreme of this semicylinder cavity communicates with each other with the atmosphere. The problem of leaking gas between nasal tube and the nostril has been solved to this patent, nevertheless is difficult for droing to nasal oxygen pipe, and the better scheduling problem of laminating nature does not relate to, and this patent limitation is great moreover, though can improve the utilization ratio of oxygen and the purity of oxygen, but only is applicable to high-risk patient and uses. Therefore, there is an urgent need for a 3D printed high flow nasal oxygen tube which is not easy to fall off, has a high oxygen utilization rate, can provide positive pressure ventilation, can be matched with the nose of a patient, and has a good fitting property.
