Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen inhalation equipment technology, and in particular to a retractable oxygen inhalation device. Background Technology
[0002] Due to technological limitations, artificially produced oxygen is often very dry. This dryness can have several negative effects on the body, specifically: First, it affects the respiratory mucosa. The mucosa in the human respiratory tract needs to be kept moist to maintain normal physiological functions, such as the clearing action of mucocili. Dry oxygen entering the respiratory tract directly accelerates the evaporation of moisture from the mucosa, leading to dryness, crusting, and a decrease in its protective function. This can easily cause respiratory infections, bleeding, and other problems, and can also cause discomfort such as sore throat and cough. Second, dry oxygen may reduce the fluid layer on the surface of the alveoli, affecting oxygen diffusion and hindering its entry into the bloodstream, resulting in low oxygen utilization efficiency. Third, dry oxygen can stimulate nerve endings in the respiratory tract, triggering a cough reflex. This not only increases patient discomfort but may also affect normal oxygen delivery and respiratory function.
[0003] Therefore, humidification is a necessary step when administering oxygen to patients. Humidified oxygen reduces irritation and damage to the respiratory mucosa, maintaining its moisture and normal function. Humidified oxygen facilitates gas exchange within the alveoli, allowing for better exchange of gases and enabling more oxygen to enter the bloodstream, thus improving oxygen utilization efficiency and alleviating the patient's hypoxia. Humidified oxygen also reduces respiratory irritation, minimizing coughing and other discomfort, allowing patients to receive oxygen therapy more comfortably.
[0004] Currently, hospitals commonly use oxygen humidification bottles to humidify oxygen, which is then delivered to patients through oxygen tubing. For patients with mildly decreased blood oxygen saturation and generally normal respiratory function, requiring only low-flow oxygen supplementation, nasal cannulas are typically used for relief. These patients are able to move around, so oxygen therapy may be paused during meals, water intake, or leaving the ward. When oxygen therapy is paused, the nasal cannula is removed, and patients often leave it carelessly, such as on the bed or table, which can easily lead to contamination. This can affect the cleanliness of the oxygen inhaled when the patient continues to receive oxygen, potentially causing cross-infection. To address this issue, medical staff can only instruct patients to place the nasal cannula in a clean bag or have a family member hold it. However, in reality, due to the lack of clean bags or the family member finding it inconvenient to hold, the nasal cannula is often left unused. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a retractable oxygen inhalation device that can accommodate a nasal oxygen tube.
[0006] To address the aforementioned problems, this utility model provides a retractable oxygen inhalation device.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] Example 1
[0026] like Figure 1As shown, a preferred embodiment of the retractable oxygen inhalation device of this utility model includes a humidification bottle 1 and a storage mechanism A. The humidification bottle 1 is used to humidify oxygen and is provided with an air outlet connector for connecting to a nasal oxygen tube 8. The storage mechanism A is detachably installed on the humidification bottle 1 and is used to store the nasal oxygen tube 8.
[0027] like Figures 2 to 4 As shown, the storage mechanism A includes a connecting sleeve 2, a hook 3, a mounting plate 4, a storage box 5, and a resetter 6. The connecting sleeve 2 is fitted onto the humidification bottle 1, and the hook 3 is installed on the connecting sleeve 2. The hook 3 is used to hang the nasal oxygen tube 8. The storage box 5 is installed on the connecting sleeve 2 and is used to store the head of the nasal oxygen tube 8, i.e., the outlet end of the nasal oxygen tube 8. The storage box 5 can be opened to place the head of the nasal oxygen tube 8 into the storage box 5 and suspend it in the air. The resetter is used to reset the storage box 5, keeping the storage box 5 in a closed state, ensuring that the nasal oxygen tube 8 is isolated from contamination when placed inside the storage box 5.
[0028] The connecting sleeve 2 has a limiting part 21, which engages with the body of the humidification bottle 1 to prevent the connecting sleeve 2 from falling off the bottle body. The diameter of the lower end of the connecting sleeve 2 is larger than the diameter of the upper end of the connecting sleeve 2, thus giving the connecting sleeve 2 a tapered portion that fits the upper part of the bottle body. This tapered portion serves as the limiting part 21, thereby preventing the connecting sleeve 2 from detaching. In this embodiment, a portion of the connecting sleeve 2 is tapered; in other embodiments, the entire connecting sleeve 2 may be tapered.
[0029] The hook 3 is L-shaped, and when combined with the bottle body, it forms a U-shape, thus ensuring that the nasal oxygen tube 8 hanging on the hook 3 will not fall off. The hook 3 is usually located below the air outlet connector for easier attachment of the nasal oxygen tube 8.
[0030] The mounting plate 4 is L-shaped, with its vertical sidewalls on the connecting sleeve 2, and its horizontal sidewalls on the bottom surface for mounting the storage box 5.
[0031] The storage box 5 has a storage cavity 50, and the head of the nasal oxygen tube 8 is placed inside the storage cavity 50. It should be noted that the nasal oxygen tube 8 usually does not contact the inner wall of the storage cavity 50 when inside, although contact is possible during sterilization. The storage box 5 is provided with a positioning groove 511 for fixing the nasal oxygen tube 8. The storage box 5 includes a box body 51 and a sealing cover 52. The box body 51 is connected to the sealing cover 52 via a hinge 7, allowing the box body 51 to rotate relative to the sealing cover 52, thereby opening the box body 51. The box body 51 has a storage groove, and the sealing cover 52 seals the storage groove to form the storage cavity 50. In this embodiment, the mounting plate 4 serves as the sealing cover 52, reducing the number of parts; in other embodiments, a separate sealing cover 52 can be provided, fixed to the mounting plate 4. The positioning groove 511 is provided on the box body 51. The size of the positioning groove 511 is the same as that of the nasal oxygen tube 8, ensuring that the nasal oxygen tube 8 can seal the positioning groove 511, preventing outside air or dust from entering the storage cavity 50, and effectively avoiding contamination of the head of the nasal oxygen tube 8. The storage box 5 is provided with a push plate 53. The outer end of the push plate 53 extends beyond the outer end of the sealing cover 52, that is, part of the push plate 53 is exposed outside the sealing cover 52, so that the push plate 53 can be easily pushed to open the box body 51. The push plate 53 is formed by extending outward from the side wall of the box body 51, that is, the push plate 53 and the box body 51 are integrally formed, reducing assembly steps. One end of the resetter 6 is located on the box body 51, and the other end of the resetter 6 is located on the sealing cover 52. In this way, the resetter 6 can deform and store force when the box body 51 rotates. After the external force applied to the box body 51 disappears, the resetter 6 pushes the box body 51 to reset so that the box body 51 fits with the sealing cover 52, that is, closes the storage box 5 to prevent external pollutants from entering the storage cavity 50.
[0032] The resetter 6 includes a first rod 61, a second rod 62, and a spring 63. The first rod 61 is fixed to the sealing cover 52, and the second rod 62 is fixed to the box body 51. The second rod 62 has an insertion hole for accommodating the first rod 61. The spring 63 is sleeved on the first rod 61 and the second rod 62, with one end of the spring 63 abutting against the box body 51 and the other end abutting against the sealing cover 52. When the box body 51 rotates, the first rod 61 inserts into the insertion hole, compressing the spring 63. When the external force on the box body 51 disappears, the spring 63 pushes the box body 51 to its reset position. When the storage box 5 is closed, the first rod 61 is not inserted into the second rod 62, thus preventing interference between the first rod 61 and the second rod 62 during installation of the storage box 5, facilitating installation. Both the first rod 61 and the second rod 62 are arc-shaped, and the centers of the first rod 61 and the second rod 62 are concentric with the center of the hinge 7 pivot, so that the first rod 61 can be smoothly inserted into the insertion hole when rotating.
[0033] When the patient stops oxygen inhalation, pressing down the push plate 53 rotates the housing 51, opening it and allowing the head of the nasal oxygen tube 8 to be placed inside. The positioning groove 511 positions the nasal oxygen tube 8, ensuring it doesn't move. Releasing the push plate 53 returns the housing 51 to its original position under the action of the spring 63, enclosing the head of the nasal oxygen tube 8. When oxygen inhalation is needed, simply push the push plate 53 again to remove the nasal oxygen tube 8 from the housing 51. This method is convenient, allowing the head of the nasal oxygen tube 8 to be hung up and enclosed in the storage box 5, ensuring it remains uncontaminated and can be used again.
[0034] Example 2
[0035] The difference between this embodiment and Embodiment 1 lies in the structure of the resetter 6.
[0036] like Figure 5 As shown, specifically, the resetter 6 includes a guide rod 64 and a spring 63. The guide rod 64 is fixed to the box body 51 of the storage box 5. The spring 63 is sleeved on the guide rod 64, with one end of the spring 63 abutting against the box body 51 and the other end abutting against the mounting plate 4. The mounting plate 4 also serves to limit the spring 63 and has a clearance hole 41. When the box body 51 is not closed, the guide rod 64 is not inserted into the mounting plate 4. When the box body 51 is rotated by an external force, the box body 51 drives the guide rod 64 to rotate, and the guide rod 64 rotates and extends into the clearance hole 41, compressing the spring 63. When the external force on the box body 51 is lost, the spring 63 pushes the box body 51 to reset.
[0037] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
