Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an adapter for a nasal oxygen cannula. Background Technology

[0002] Oxygen therapy is one of the most commonly used treatments in clinical practice. It treats hypoxia caused by various reasons by inhaling high concentrations of oxygen, increasing the dissolved oxygen in the blood plasma, thereby improving tissue oxygenation and promoting metabolism. Common oxygen therapy methods include: nasal cannula and nasal oxygen therapy, face mask oxygen therapy, endotracheal tube oxygen therapy, electronic pulse oxygen therapy, mechanical ventilation, and hyperbaric oxygen therapy. Nasal cannulas and face masks, as medical equipment used in oxygen therapy, play a significant role in medical settings such as emergency rooms, operating rooms, general wards, and ICUs. They are used to relieve hypoxia symptoms and maintain vital signs balance in patients with acute respiratory distress. Patients with chronic respiratory diseases such as asthma can also receive necessary oxygen support through nasal cannulas and face masks. They are also used for pre- and post-operative care, helping patients recover quickly and reducing postoperative complications. Furthermore, they can provide timely oxygen supplementation to reduce the impact of altitude sickness when entering high-altitude areas. In medicine, oxygen therapy is an important treatment method, becoming one of the most basic and common medical approaches, widely used in clinical departments, emergency departments, operating rooms, and intensive care units. Oxygen therapy can increase arterial blood oxygen partial pressure and arterial blood oxygen saturation, increase arterial blood oxygen content, correct various hypoxic conditions, promote tissue metabolism, and maintain bodily vital functions. During oxygen therapy, auxiliary devices are inevitably needed, such as nasal cannulas, simple masks, oxygen reservoir masks, and simple respirators. Among these, nasal cannulas have become commonly used in low-flow oxygen supply systems due to their ease of clinical use, good patient tolerance, and the ability for patients to move freely, eat, and converse during oxygen therapy. However, because existing nasal cannulas and adapters are mostly bonded, the cannulas can easily become kinked if the patient moves during oxygen therapy.

[0003] Therefore, to meet practical needs, an adapter for nasal oxygen cannulas is provided. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this application is to provide an adapter for a nasal oxygen tube, which is equipped with a rotary joint and a one-way valve plate. During use, it can enable patients to breathe independently and has the function of 360-degree free rotation, so as to avoid the tube from being kinked and effectively meet the actual use needs.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides an adapter for a nasal oxygen cannula, characterized in that the adapter comprises:

[0007] The cross-shaped conduit body includes a first channel and a second channel arranged along a first direction, and a third channel and a fourth channel arranged along a second direction, wherein the first direction and the second direction are perpendicular to each other;

A boss groove matching the outer contour of the blocking boss of the first connecting rod is provided at the center of the inner wall of the top plate of the threaded cap.

[0011] The threaded cap is configured such that when the threaded cap is rotated to the position closest to the first channel, the boss groove abuts against the first connecting rod blocking boss, so that the first connecting rod blocking boss blocks the first through hole.

[0012] The free end of the second channel is open;

[0013] The free end of the third channel is open and is hinged with a protective cap;

During use, it enables the patient to breathe independently while allowing for 360-degree free rotation, preventing the cannula from kinking and effectively meeting practical usage needs.

[0036] To achieve the aforementioned technical effects, the overall concept of this application is as follows:

[0037] An adapter for a nasal oxygen cannula, the adapter comprising:

[0038] The cross-shaped conduit body 1 includes a first channel 10 and a second channel 11 arranged along a first direction, and a third channel 12 and a fourth channel 13 arranged along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0039] The free end of the first channel 10 is a barrel-shaped structure and is provided with a first channel cover plate 100.

[0048] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0049] See Figures 1-6 As shown, this application embodiment provides an adapter for a nasal oxygen cannula, the adapter comprising:

[0050] The cross-shaped conduit body 1 includes a first channel 10 and a second channel 11 arranged along a first direction, and a third channel 12 and a fourth channel 13 arranged along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0051] The free end of the first channel 10 is a barrel-shaped structure and is provided with a first channel cover plate 100. The center of the first channel cover plate 100 is provided with a first through hole 101. The first channel cover plate 100 is provided with a first valve plate 102. The center of the first valve plate 102 is provided with a first valve plate connecting rod 103. The free end of the first valve plate connecting rod 103 is provided with a first connecting rod blocking boss 104.

[0052] The length of the first valve plate connecting rod 103 is greater than the depth of the first through hole 101, the outer diameter of the first valve plate connecting rod 103 is smaller than the inner diameter of the first through hole 101, and the maximum dimension of the outer contour of the first connecting rod blocking boss 104 is greater than the inner diameter of the first through hole 101.

[0053] A barrel-shaped threaded cover 4 is provided at the free end of the first channel 10. Multiple threaded cover through holes 40 are symmetrically provided on the top surface of the threaded cover 4. The inner wall of the side wall of the threaded cover 4 is threadedly connected to the outer wall of the free end of the first channel 10. A boss groove 41 matching the outer contour of the blocking boss 104 of the first connecting rod is provided at the center of the inner wall of the top plate of the threaded cover 4.

[0054] The threaded cap 4 is configured such that when the threaded cap 4 is rotated to the position closest to the first channel 10, the boss groove 41 abuts against the first connecting rod blocking boss 104, so that the first connecting rod blocking boss 104 blocks the first through hole 101.

[0055] The free end of the second channel 11 is open;

[0056] The free end of the third channel 12 is open, and a protective cap 3 is hinged thereon;

[0057] The free end of the fourth channel 13 is open, and the inner wall is provided with a first protruding ring 130;

[0058] The threaded pipe 5 has a rotary joint 2 at one end. The rotary joint 2 is connected to the first protruding ring 130 of the fourth channel 13 through a second protruding ring 20 and a third protruding ring 21 spaced apart on its surface.

[0059] The rotary joint 2 is configured such that when the second convex ring 20 mates with the first convex ring 130, the rotary joint 2 can rotate 360° within the fourth channel 13.

[0060] It should be noted that both the second channel 11 and the fourth channel 13 correspond to the patient end.

[0061] It should be noted that the second protruding ring 20 and the third protruding ring 21 are spaced apart on the rotary joint 2, forming a limiting space between them. When the first protruding ring 130 is located in this limiting space, the rotary joint 2 can rotate 360° without falling off.

[0062] Furthermore, the length of the first valve plate connecting rod 103 is slightly greater than the depth of the first through hole 101, thereby enabling the first valve plate 102 to perform its function and meet diverse usage requirements.

[0063] In this embodiment, a rotary joint and a one-way valve are provided. During use, the device allows for 360-degree free rotation while enabling the patient to breathe independently, thus preventing the catheter from kinking and effectively meeting practical usage requirements.

[0064] It should be noted that the technical solution of this application embodiment has at least two usage methods, as detailed below:

[0065] In the first method, during oxygen therapy, the oxygen source is turned on, the protective cap 3 is opened, and the threaded cap 4 is tightened so that it is as close as possible to the first channel cover plate 100 of the first channel 10. The first connecting rod blocking boss 104 is also squeezed so that the first valve plate connecting rod 103 cannot be displaced in the first through hole 101, thereby restricting the first valve plate 102. At this time, there is a certain gap between the first valve plate 102 and the first channel cover plate 100, and the threaded cap through hole 40 on the top surface of the threaded cap 4 allows for flow between the inside of the cross tube body 1.

[0066] The second method involves turning off the oxygen source and covering the patient's cap 3 when the patient is breathing independently, loosening the threaded cap 4, and stopping the compression of the first connecting rod blocking boss 104. At this time, the first valve plate 102 will take effect.

[0067] Furthermore, the inner wall cross-sections of the first channel 10, the second channel 11, the third channel 12, and the fourth channel 13 are circular.

[0068] Furthermore, the inner diameter of the first channel 10 is the same as the inner diameter of the second channel 11.

[0069] Furthermore, the inner diameter of the third channel 12 is smaller than the inner diameters of the first channel 10, the second channel 11, and the fourth channel 13.

[0070] Furthermore, the cap 3 has a barrel-shaped structure, and its inner diameter matches the outer diameter of the free end of the third channel 12;

[0071] The outer wall of the cap 3 is hinged to the outer wall of the free end of the third channel 12.
