The traditional oxygen inhalation tube firstly sleeves the main tube body on the ears of an oxygen patient, and then the nasal plug on the oxygen inhalation tube is inserted into the nostrils of the oxygen patient to inhale oxygen. However, the nasal plugs of the conventional oxygen inhalation tube have fixed spacing and fixed length, and are not comfortable to use because the conventional oxygen inhalation tube cannot be adjusted adaptively when applied to patients with different nasal types; especially, the nasal cavity of a human body is extremely sensitive, nasal plugs with improper length and spacing easily cause damage to nasal mucosa or nasal septum, and nasal bleeding can be generated in severe cases, so that great inconvenience is brought to patients, nursing workload and time cost of medical staff are increased, and urgent solution is needed.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides an adjustable oxygen inhalation tube with a reasonable structure, which can realize the functions of online sterilization and convenient adjustment of the length of a nasal plug, synchronously has the advantages of simple structure, convenient operation and high comfort level, and is beneficial to clinical use.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an oxygen tube with adjustable, is used for inserting the nasal obstruction of patient's nasal cavity including being responsible for the body and arranging on being responsible for the body, and the entrance point of nasal obstruction communicates and is responsible for the body lumen, and the exit end of nasal obstruction constitutes oxygen outlet, its characterized in that: the appearance of the nose plug is in a straight barrel shape with double layers nested, and the nose plug is formed by mutually sleeving an inner barrel body and an outer barrel body with consistent barrel mouth directions; the openings of the inner barrel body and the outer barrel body are provided with medical plastic sections for connecting the inner barrel body and the outer barrel body, so that a transition cavity for oxygen to flow is arranged between the inner barrel body and the outer barrel body; the outer barrel body radially penetrates through the main pipe body along the main pipe body, a communication hole for communicating the transition cavity with the main pipe body cavity is formed in the outer barrel body, a passing hole is formed in the inner barrel body in a penetrating mode so as to communicate the transition cavity with the inner barrel body cavity, the barrel mouth of the inner barrel body forms the oxygen outlet, the nasal plug and the main pipe body form a cross layout at the moment, and the length of the bendable region of the medical plastic section is equal to the adjustable length of the nasal plug.

Preferably, the pipe diameter of the main pipe body is larger than the outer diameter of the outer barrel body, and a corrugated pipe section or an elastic pipe section for connecting the outer barrel body and the barrel bottom section of the outer barrel body are arranged between the outer wall of the main pipe body and the barrel bottom section.

Preferably, the rear end of the inner barrel body and the barrel bottom section of the outer barrel body are connected with each other through a coaxially arranged annular ring; the annular ring, the rear end of the inner barrel body and the barrel bottom section of the outer barrel body are enclosed together to form an air bag cavity.

Preferably, the two groups of nasal plugs are arranged on the main pipe body in parallel with each other in an axial line manner; the bottom sections of the two groups of nasal obstruction outer barrel bodies are connected with each other through a connecting bridge, and the connecting bridge, the outer walls of the two groups of outer barrel bodies and a section of main pipe body between the two groups of outer barrel bodies are enclosed together to form an operating ring for fingers to be sleeved in.

Preferably, the two groups of nasal plugs are arranged on the main pipe body in parallel with each other in an axial line manner; the rear end of the inner barrel body is coaxially matched with a rotary stud in a rotary mode, the rotary stud extends outwards along the axis of the inner barrel body and penetrates through the bottom surface of the outer barrel body, and a thread matching relation is formed between the rotary stud and a reserved hole in the bottom surface of the outer barrel body.

Preferably, one section of the main pipe body between the two groups of the outer barrel bodies which are arranged in parallel is a corrugated pipe.

The utility model has the beneficial effects that:

1) through the scheme, the oxygen can pass through the main pipe body, the communicating hole, the transition cavity, the passing hole, the inner barrel body cavity and the oxygen outlet in sequence by adopting the internally and externally nested nasal plug structure, so that the oxygen supply smoothness is ensured, and the inherent oxygen supply effect of the oxygen inhalation tube is ensured. On the other hand, the nasal plug structure nested inside and outside is utilized, and the bendable medical plastic section is matched, so that the nasal plug has the adjustability of the extending length of the nasal cavity of a patient. When the nasal plug needs to be adjusted, the outer barrel body can extrude the inner barrel body only by holding the barrel bottom section of the outer barrel body, which is positioned outside the nasal cavity of a patient, and then the outer barrel body is pulled outwards by applying force, so that the front end of the inner barrel body can generate axial positioning action on the barrel mouth section of the outer barrel body, the action is compensated by the bending action of the medical plastic section, and the compensation process realizes the function of shortening and adjusting the extending length of the nasal plug relative to the nasal cavity of the patient; and vice versa.

Obviously, in actual operation, the adjustment of the extending length of the nasal plug can also be realized by directly adjusting the part of the nasal plug extending into the nasal cavity of the patient, for example, by directly adjusting the barrel mouth area by adopting a thread fit mode or by adopting an internal adjusting mode such as a corrugated pipe and the like. However, in practice, people find that the adjustment is often on-line according to different requirements of different patients on the insertion length, that is, only inserting into the nasal cavity of the patient can know whether the insertion length of the nasal plug is comfortable; at this time, as the internal adjustment mode is adopted, no matter whether mucus in the nasal cavity of the patient is attached to the nasal plug, and then the nasal plug is pulled out, the problems of pollution and even cross infection can be caused; such exposure adjustment may also cause external germs to adhere to the nasal plugs again, and the external germs may accompany the reinsertion of the nasal plugs, causing a problem of foreign body infection in the nasal cavities of the patients. At the same time, the adjustment of the insertion length must be repeated, rarely with success, so that the above-mentioned exposed adjustment method is necessarily accompanied by repeated large-stroke insertion relative to the nasal cavity, which obviously also easily causes damage and bleeding of the nasal mucosa or nasal septum, i.e. direct damage to the patient, increases the risk of infection, which is to be avoided as much as possible.

In conclusion, the utility model indirectly controls the front end of the nose plug to generate the telescopic action by operating the rear end of the nose plug, ensures the normal adjustment function of the extension length of the nose plug, does not need to frequently insert and pull the nose plug, namely can perform the small-amplitude sterile and convenient adjustment function of the extension length on line when the nose plug is in an insertion state, synchronously has the advantages of simple structure, convenient operation and high comfort level, and is beneficial to clinical use.

2) As a further preferable scheme of the above scheme, a corrugated pipe section or an elastic pipe section for connecting each other may be provided between the barrel bottom section of the outer barrel body and the outer wall of the main pipe body, in other words, the barrel bottom section of the outer barrel body forms an independent adjusting structure with respect to the main pipe body at this time; therefore, when the rear ends of the outer barrel body and the inner barrel body are drawn, the corresponding corrugated pipe sections or the elastic pipe sections can generate a telescopic effect, so that the corresponding traction follow-up action cannot be generated at the barrel mouth sections of the main pipe body and the outer barrel body, only the inner barrel body can generate an axial reciprocating action, and finally the reliable and accurate adjusting function of the extending length of the nasal plug is ensured.

3) The design of the balloon cavity and the annular ring is another bright spot part of the utility model. Because the nasal obstruction is thin, when the outer wall of the barrel bottom section of the outer barrel body is held by a hand, the sliding dislocation of the inner barrel body and the outer barrel body is easy to occur, or the barrel bottom section of the outer barrel body is not held by the hand, so that the inconvenience of adjusting the extension length can be caused. In view of the above, on the one hand, the utility model designs the annular ring, so that the rear end of the inner barrel body and the barrel bottom section of the outer barrel body are integrated into a whole, that is, an integrated structure is formed, when the barrel bottom section of the outer barrel body is pulled outwards by a force, the rear end of the inner barrel body and even the whole inner barrel body immediately respond and generate a follow-up pulling-outwards action, so as to ensure the convenience and high responsiveness of the adjustment operation. On the other hand, the rear end of annular ring, interior staving and the barrel head section of outer staving enclose jointly and close and form the gasbag chamber, when holding between the fingers and holding this position, the gasbag chamber produces the atress and warp, becomes the arc slice of more laminating finger face shape by globular for when holding between the fingers the outer wall of short and tiny outer staving, holistic holding between the fingers the dynamics and hold between the fingers the travelling comfort stronger, frictional force is also higher, and the simple operation nature also can obtain effectively promoting.

4) And further, also can consider to set up the operation ring at the rear end of two sets of nasal plugs to promote the simple operation nature, once draw simultaneously can operate two sets of nasal plugs simultaneously, efficiency is obviously higher.

5) The utility model also provides another operation mode of the nasal plug, namely, the function of adjusting the axial position of the inner barrel body on line is realized through the rotary stud and the outer barrel body matched with the lead screw nut, and the adjustment is very simple and convenient.

6) The utility model can not only realize the purpose of online adjustment of the extension length of the nasal plugs by the scheme, but also arrange the corrugated pipes between two groups of outer barrel bodies which are arranged in parallel to form a section of main pipe body, thereby realizing the effect of adjusting the distance between the two groups of nasal plugs and further improving the application range of the utility model.

Detailed Description

For the purposes of understanding, the utility model will be further described in its specific structure and mode of operation with reference to the accompanying drawings in which:

the specific structure of the utility model is shown in fig. 1-4, and the main structure thereof comprises a main pipe 10 and two groups of nasal plugs 20; when assembled, the diameter of the lumen of the main tube 10, i.e. the tube diameter, should be larger than the outer diameter of the nasal plug 20, so that the nasal plug 20 can penetrate into the main tube 10 along the radial direction of the main tube 10 and penetrate through the main tube 10, and finally the cross-shaped layout between the nasal plug 20 and the main tube 10 is formed as shown in fig. 1-4. For convenience of description, the portion of the nasal prong 20 that is accessible to the nasal cavity of the patient is referred to herein as the forward end, and the corresponding rearward end of the prong 20 forms the operative end that is adjustable. Wherein:

fig. 1-4 are schematic structural diagrams of two embodiments of the present invention. As can be seen, each set of nasal prongs 20 is formed by mating a set of inner barrel 21 and a set of outer barrel 22 that nest with one another. The bung holes of the inner and outer barrels 21 and 22 are facing the same such that the bung hole of the inner barrel 21 forms an oxygen outlet. In fig. 1, it can be seen that, when the nasal prong 20 of this type extends through the main tube 10, the outer barrel 22 is actually interrupted by the main tube 10 to form two parts, a bung section 22b and a bottom section 22a, which are separate or independent from each other. The inner tub 21 is of an integral structure since it is located inside the outer tub 22. In order to ensure the normal circulation of oxygen in the nasal plug 20, the bung holes of the inner barrel 21 and the outer barrel 22 are sealed by the medical plastic section 23, so that a transition cavity is formed between the inner barrel 21 and the outer barrel 22. When oxygen is supplied, oxygen passes through the main pipe body 10, the communicating holes at the outer barrel body 22, the transition cavity, the passing holes 21a at the inner barrel body 21, the barrel cavity of the inner barrel body 21 and the oxygen outlet, thereby ensuring the smoothness of oxygen supply. When the adjustment is needed, the outer barrel body 22 can be extruded and deformed only by holding the barrel bottom section 22a outside the nasal cavity of the patient, so that the outer barrel body is easier to hold; then, the front end of the inner barrel body 21 can generate axial displacement motion to the barrel mouth section 22b of the outer barrel body 22 by pulling out the force, the motion is compensated by the bending motion of the medical plastic section, and the compensation process realizes the function of shortening and adjusting the extending length of the nasal plug 20 relative to the nasal cavity of the patient; and vice versa.

On the basis of the above scheme, the present invention provides two specific embodiments:

fig. 1-3 illustrate the use of annular ring 24 and bladder cavity 25 to form a removable structure, optionally with an operating ring 26 to improve operating efficiency. Taking the structure shown in fig. 3 as an example, in actual operation, a medical worker can insert the index finger into the operation ring 26, and the thumb and the middle finger respectively cooperate with the index finger to clamp the rear ends of the two sets of nasal plugs 20, and at this time, the rear ends of the two sets of nasal plugs 20 are deformed as shown in fig. 2, so as to improve the clamping effect. Then, the medical staff starts to apply an external force to pull the nasal plug 20 outwards, and since the bellows section as shown in fig. 3 is arranged between the bottom section 22a of the outer barrel 22 and the main barrel, and the bottom section 22a of the outer barrel 22 and the bung section 22b are separated from each other, the bottom section 22a of the outer barrel 22, the annular ring 24 and the inner barrel 21 start to synchronously generate an axial outwards pulling action, and drive the medical plastic section 23 to generate an inwards rolling action, so that the function of shortening the extending length of the nasal plug 20 is realized. When the extension length is required, the barrel bottom section 22a of the outer barrel 22 is pushed inward. Obviously, in this case, the windable length of the medical plastic section 23, i.e. the length of its bendable region, is equal to the adjustable length of the protruding length of the nasal prong 20; when the limit is exceeded, the nose plug 20 cannot be further extended or shortened in length, regardless of the force applied, due to the extent of the curve of the section of medical plastic. It should be noted that the medical plastic section 23 cannot adopt an elastic telescopic structure, so as to ensure that the axial stroke generated by the inner barrel 21 can be completely reflected on the medical plastic section 23, and finally, the purpose of accurately adjusting the extending length of the nasal plug 20 is achieved.

As for fig. 4, the difference is that a reserved hole is arranged at the bottom section 22a of the outer barrel body 22, so that the function of online adjustment of the axial action of the inner barrel body 21 is realized through the threaded engagement of the rotary stud 27 which is rotatably engaged on the inner barrel body 21 and the reserved hole, and the online adjustment effect of the extension length of the nasal plug 20 can also be realized.
