Description

Anti-slip nasal oxygen cannula and ear fixer used by same

Technical Field

The utility model relates to an apparatus for influencing the respiratory system of a patient by a gas treatment method, in particular to a medical anti-slip nasal oxygen catheter and an ear fixer used by the same.

Background

The nasal oxygen cannula used in the prior art is a product made of polyethylene and silica gel as raw materials, and supplies oxygen to a human body through a nasal plug on the nasal oxygen cannula after being connected with an oxygen delivery system. The oxygen supply for the human body through the nasal oxygen tube can improve the partial pressure of the blood oxygen of the artery and the oxygen saturation of the blood oxygen of the artery, increase the content of the blood oxygen of the artery, promote the metabolism, maintain the life activity of the organism, and have very important status in clinic.

However, the nasal oxygen tube is easy to fall off during use, and serious consequences can be caused if medical care personnel do not find the nasal oxygen tube in time after the nasal oxygen tube falls off. Because nasal oxygen hose includes oxygen therapy pipe, divide the oxygen pipe, the nasal obstruction, ear-hang isotructure, for the patient oxygen suppliment in the nasal obstruction is stuffed into the nostril, after the nasal obstruction was stuffed into the nostril, because the patient is uncomfortable, unconsciousness or head activity lead to easily coming off, for this reason prior art traditional chinese medical personnel often utilize the sticky tape will divide the oxygen pipe to paste on the face, perhaps use the ear-hang will divide the oxygen pipe to be fixed in on the ear, it is very effective method to utilize the sticky tape to paste, but make the patient more uncomfortable easily, local skin allergy condition appears, the use of ear-hang can the alleviating of certain degree come off, but there is a new problem, different patient's face is not of uniform size promptly, the position of ear-hang need can adjust just can be better be used.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a nasal oxygen cannula is taken off in antiskid and ear's fixer that uses can reduce the chance that nasal oxygen cannula slipped from patient's face, also can adapt to the patient of different head circumferences and use.

Ear's fixer, including root and auricle portion, the root is used for being fixed in branch oxygen pipe with auricle portion slidable on, auricle portion longitudinal section is for connecting gradually the closed face of enclosing by first arc, first line segment, first transition arc, second line segment, third arc, fourth arc, second transition arc, third line segment and fourth line segment, preferred, ear's fixer adopts silica gel material to make and forms, and silica gel material can make ear's fixer and branch oxygen pipe time keep great frictional force, for being fit for the not patient of face equidimension, when being fixed in patient's ear with ear's fixer on, can reduce ear's fixer and divide the relative movement between the oxygen pipe, prevent the slippage.

Further, the root part and the auricle part are integrally formed or are arranged in a split mode.

In order to make auricle portion of ear fixer and patient's ear inseparabler laminating be in the same place, realize better fixed action, prevent that nasal obstruction from slipping in the nostril: the length ratio of the third line segment to the fourth line segment is as follows: 5-6: 3-4, the ratio of the first arc radius to the fourth line segment length is 1-1.2: 3, the central angle corresponding to the first arc is 115-125 degrees, the included angle formed between the first line segment and the second line segment is 12-16 degrees, the centers of the third arc and the fourth arc are positioned at two sides of the tangent line at the intersection point of the two arcs, and the ratio of the radiuses corresponding to the fourth arc, the third arc and the first arc is 1: 1.5-1.6: 2, the central angles corresponding to the third arc and the fourth arc are 57-60 degrees.

Another object of the present invention is to provide an anti-slipping nasal oxygen cannula for use in the ear fixator, which comprises an oxygen tube, an oxygen separation tube, a nasal plug, an ear fixator and a connector for connecting the oxygen tube to an oxygen therapy device.

And the root part of the ear fixer comprises a fixed part and a movable part hinged with the fixed part, a spring is arranged at the hinged position, and a through hole for the oxygen distribution pipe to pass through is arranged between the fixed part and the movable part. When the nasal oxygen tube is used, after the position between the ear part and the nasal plug of a patient is determined, the movable part is opened, so that the nasal oxygen tube moves in the root part, and the movable part is buckled after the movable part moves to a proper position, so that fixation is realized.

Furthermore, a sleeve is sleeved at the connecting position of the two oxygen distribution pipes, a hole for the nasal plug to penetrate out is formed in the sleeve, and a metal sheet capable of guiding the sleeve to be bent is arranged in the sleeve. The sheetmetal that sets up in the sleeve pipe, for the material that can realize the buckle of many times different angles, this material is the existing material of prior art (for example the thin strip type structure that can buckle that uses on the gauze mask), the utility model discloses do not make the improvement to this material. The metal sheet is bent to form a certain angle between the two nose plugs, so that the distance between the two nose plugs can be finely adjusted, and the discomfort of a patient caused by oxygen directly rushing into the nostrils can be buffered.

Furthermore, the end parts of the two oxygen distribution pipes can be directly connected with the nasal plug; the ends of the oxygen separation pipes can be connected in series: the connecting position is provided with a corrugated pipe, and the nasal plug is arranged on the oxygen distributing pipes at the two ends of the corrugated pipe. The corrugated pipe has the function of stretching or lengthening, and further can be used for adjusting the distance between the two nasal plugs, and the length of the hole in the sleeve through which the nasal plug penetrates is correspondingly lengthened for adapting to the adjustment of the distance.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the ear fixer of the utility model is made of silica gel, the friction force at the contact position of the root part and the oxygen distributing pipe is large, so that the relative movement can be reduced, the position of the ear fixer can not easily slide, and the nose plug can be prevented from slipping from the nostril;

(2) the distance between the two nasal plugs is adjustable, so that the nasal plugs can be conveniently used by more patients, the nasal plugs can form a certain angle with the nostrils, and the discomfort caused by direct flushing of oxygen into the nostrils is reduced;

(3) the fixing mode between ear's fixer root and the branch oxygen pipe can make ear's fixer can freely remove on dividing the oxygen pipe, can reach better relatively fixed effect when needing to fix.
