Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a high-flow humidification therapy oxygen supply nasal plug structure. Background Technology
[0002] Chinese patent document CN221815028U discloses a technical solution entitled "A Nasal Prop for a High-Flow Nasal Humidifier". The technical solution includes the following technical features: it comprises three parts: a breathing circuit connection port, an asymmetric nasal plug connector, and an extension tube; the middle part of the asymmetric nasal plug connector is the connector part, and the two ends are connecting buckles. The bottom part of the connector part is installed in an oblong mounting hole, and the upper part includes two nasal plug connectors of different sizes: a small nasal plug connector and a large nasal plug connector; the bottom part of the connector part is triangular, narrow at the bottom and wide at the top, hollow inside, and has two symmetrical ventilation holes on the bottom wall, which are connected to the two nasal plug connectors respectively.
[0003] While this technical solution improves the safety of invasive endoscopy by using small and large nasal plug connectors, after the invasive endoscopy, there are still two nasal plug connectors, one large and one small, remaining on the patient. Furthermore, the small and large nasal plug connectors cannot be replaced (as shown in the attached drawings of the patent document, these two nasal plug connectors are directly fabricated onto the lower component, so they cannot be disassembled and replaced separately). Therefore, when only high-flow humidification treatment is performed, there will be a situation where the two nasal plug connectors, one large and one small, supply oxygen to the two nostrils respectively. This will result in less oxygen supply to the side with the smaller nasal plug connector. In addition, since the two nasal plug connectors are connected to the two ventilation holes separately, the oxygen supply on the side with the larger nasal plug connector changes less. This can easily lead to insufficient oxygen supply during high-flow humidification therapy, which may affect the treatment effect on the patients.
[0004] At the same time, when high-flow humidification therapy and invasive endoscopy are performed at the same time, the relevant examination instruments can only be inserted through the nostril corresponding to the small-sized nasal plug connector. When the patient's nostril is not suitable for insertion of examination instruments (due to inflammation, polyps, recent nasal surgery, etc.), this will cause great trouble for the invasive endoscopy.
[0005] Therefore, it is essential to design an oxygen supply nasal plug structure that can switch between different sizes to solve the aforementioned technical problems. Utility Model Content
[0006] The purpose of this invention is to solve the above-mentioned problems and shortcomings by providing an oxygen supply nasal plug structure that can switch between large and small nasal tubes. This structure allows for easy selection of an oxygen tube of appropriate diameter according to different usage conditions. It not only ensures smooth completion of patient examinations or treatments under various usage conditions but also effectively guarantees sufficient oxygen supply under various usage conditions, thereby reducing adverse effects on the treatment of related patients. Furthermore, it allows for easy selection of the appropriate nostril for invasive endoscopic examinations based on the condition of the patient's nostrils, effectively solving the difficulties encountered during related examinations.
[0007] The technical solution of this utility model is implemented as follows: An oxygen supply nasal plug structure capable of switching between large and small nasal tubes is characterized by comprising an oxygen supply chamber shell, at least one large-diameter nasal tube, and at least one small-diameter nasal tube. The inner cavity of the oxygen supply chamber shell is the oxygen supply chamber, and two positioning slots are arranged side by side on the outer wall of the oxygen supply chamber shell. The bottom of the two positioning slots is respectively provided with an oxygen supply hole that penetrates into the oxygen supply chamber. One end of the large-diameter nasal tube and the small-diameter nasal tube are respectively provided with an insert head that matches the positioning slot. The large-diameter nasal tube and the small-diameter nasal tube are respectively inserted into the two positioning slots through the corresponding insert head, and the large-diameter nasal tube and the small-diameter nasal tube are connected to the oxygen supply chamber through the corresponding insert head and the oxygen supply hole.
[0008] Preferably, the positioning slot is a vertically extending T-shaped slot, and the lower end of the T-shaped slot is closed, and the insert tube head can be inserted into the T-shaped slot from the upper end downward.
[0009] Preferably, the insert tube head includes an inner tube and a convex ring portion. The convex ring portion is disposed on the outer circumferential surface of the inner tube. The inner tube is embedded in the slot of the T-shaped groove, and the convex ring portion is embedded in the inner groove of the T-shaped groove.
[0010] Preferably, a reinforcing protrusion is provided on the outer wall of the oxygen supply chamber shell, and the reinforcing protrusion is located on the slot of the positioning groove.
[0011] Preferably, connecting lugs are provided on the left and right outer walls of the oxygen supply chamber shell, and an elastic band connects the two connecting lugs.
[0012] Preferably, soft silicone sheets are attached to the inner wall of the oxygen supply chamber shell and the inner wall of the connecting lug, and a soft cloth cover is fitted onto the elastic band.
[0013] The beneficial effects of this invention are as follows: In this oxygen supply nasal plug structure that allows switching between large and small nasal tubes, the oxygen supply chamber is formed by utilizing the inner cavity of the oxygen supply chamber shell. This creates a single-chamber, large-diameter oxygen supply chamber. This allows for increased oxygen flow on the large-diameter nasal tube side when a small-diameter nasal tube is used on one side, resulting in reduced oxygen flow. This ensures that the overall oxygen supply remains within a normal range, better guaranteeing the smooth progress of related treatments. By creating two identical positioning slots and two identical oxygen supply holes, and by providing matching insert heads at the ends of both the large-diameter and small-diameter nasal tubes, it is convenient and stable to install the large-diameter and small-diameter nasal tubes, ensuring stable communication between them and the oxygen supply chamber. This structure allows for the selective installation of oxygen tubes with different diameters, such as those with a larger left side and a smaller right side, or vice versa, depending on the usage conditions. This facilitates the selection of oxygen tubes with appropriate diameters for different applications, ensuring smooth patient examinations and treatments under various conditions and guaranteeing sufficient oxygen supply, thus minimizing adverse effects on patient care. Furthermore, it allows for the selection of appropriate nostrils for invasive endoscopic procedures based on the patient's nasal structure, effectively resolving difficulties encountered during these examinations.

[0021] like Figures 1 to 5As shown, the present invention discloses an oxygen supply nasal plug structure capable of switching between large and small nasal tubes, comprising an oxygen supply chamber shell 1, at least one large-diameter nasal tube 2, and at least one small-diameter nasal tube 3. The inner cavity of the oxygen supply chamber shell 1 is an oxygen supply chamber 11. Two positioning slots 12 are arranged side by side on the outer wall of the oxygen supply chamber shell 1. The bottom of the two positioning slots 12 is respectively provided with oxygen supply holes 13 that penetrate into the oxygen supply chamber 11. One end of the large-diameter nasal tube 2 and the small-diameter nasal tube 3 is respectively provided with an insert head 4 that matches the positioning slot 12. The large-diameter nasal tube 2 and the small-diameter nasal tube 3 are respectively inserted into the two positioning slots 12 through the corresponding insert head 4, and the large-diameter nasal tube 2 and the small-diameter nasal tube 3 are connected to the oxygen supply chamber 11 through the corresponding insert head 4 and the oxygen supply hole 13.
[0022] In this oxygen supply nasal plug structure that can switch between large and small nasal tubes, the oxygen supply chamber 11 is formed by utilizing the inner cavity of the oxygen supply chamber shell 1. This creates a single-chamber, large-diameter oxygen supply chamber 11. This allows for increased oxygen flow on the side with the large-diameter nasal tube 2 when the oxygen flow is reduced due to the use of the small-diameter nasal tube 3 on one side. This ensures that the overall oxygen supply remains within the normal range, better guaranteeing the smooth progress of related treatments. By providing two identical positioning slots 12 and two identical oxygen supply holes 13, and by setting fitting tube heads 4 at the ends of the large-diameter nasal tube 2 and the small-diameter nasal tube 3 that match the positioning slots 12, it is convenient and stable to install the large-diameter nasal tube 2 and the small-diameter nasal tube 3 into place, ensuring stable communication between the large-diameter nasal tube 2, the small-diameter nasal tube 3, and the oxygen supply chamber 11. This structure allows for the selective installation of oxygen tubes with different diameters, such as those with a larger left side and a smaller right side, or vice versa, depending on the usage conditions. This facilitates the selection of oxygen tubes with appropriate diameters for different applications, ensuring smooth patient examinations and treatments under various conditions and guaranteeing sufficient oxygen supply, thus minimizing adverse effects on patient care. Furthermore, it allows for the selection of appropriate nostrils for invasive endoscopic procedures based on the patient's nasal structure, effectively resolving difficulties encountered during these examinations.
[0023] This nasal plug structure, which can switch between different sizes, is very suitable for high-flow humidification therapy, and it can bring very good therapeutic effects to high-flow humidification therapy.
[0024] like Figures 2 to 7 As shown, in this oxygen supply nasal plug structure that can switch between large and small nasal tubes, the two positioning slots 12 are the same size and are arranged symmetrically on the left and right. The two oxygen supply holes 13 are also the same diameter and are arranged symmetrically on the left and right. The size of the insert head 4 on the large-diameter nasal tube 2 and the small-diameter nasal tube 3 is the same. The inner diameter of the large-diameter nasal tube 2 is larger than the inner diameter of the small-diameter nasal tube 3, and the outer diameter of the large-diameter nasal tube 2 is larger than the outer diameter of the small-diameter nasal tube 3. This can well meet the needs of actual use.
[0025] like Figures 1 to 5 As shown, the positioning slot 12 is a vertically extending T-shaped slot, with its lower end closed, allowing the insert head 4 to be inserted into the T-shaped slot from the upper end downwards. The T-shaped slot not only facilitates the installation and positioning of the insert head 4 but also helps to achieve stable positioning. When the insert head 4 is fully inserted and in contact with the closed position of the T-shaped slot, its inner hole aligns perfectly with the oxygen supply port 13. This allows the large-diameter nose tube 2 and the small-diameter nose tube 3 to accurately connect to the oxygen supply chamber 11 through the corresponding insert head 4 and oxygen supply port 13, improving the convenience and accuracy of their installation and positioning.
[0026] The large-diameter nose tube 2 and the corresponding insert head 4 are integrally formed by an elastic plastic structure, such as a polyurethane elastic plastic structure (PU) or a polyester elastic plastic structure (PE). This allows the insert head 4 to be tightly embedded in the positioning slot 12, which not only achieves accurate positioning of the insert head 4, but also ensures high sealing at the insertion point of the insert head 4. This enables accurate and stable installation of the large-diameter nose tube 2 and the small-diameter nose tube 3, thus perfectly meeting the needs of practical use.
[0027] like Figures 2 to 5 As shown, the mounting head 4 includes an inner tube 41 and a convex ring 42. The convex ring 42 is disposed on the outer circumferential surface of the inner tube 41. The inner tube 41 is embedded in the slot of the T-shaped groove, and the convex ring 42 is embedded in the inner groove of the T-shaped groove. This mounting head 4 is very simple and reliable, which not only facilitates manufacturing but also achieves accurate installation and positioning, thereby enabling the large-diameter nose tube 2 and the small-diameter nose tube 3 to accurately and stably connect with the corresponding oxygen supply port 13.
[0028] like Figure 4 As shown, a reinforcing protrusion 14 is provided on the outer wall of the oxygen supply chamber shell 1, and the reinforcing protrusion 14 is located on the groove of the positioning slot 12. The reinforcing protrusion 14 serves to strengthen the structure at the opening of the positioning slot 12, thereby ensuring that the oxygen supply chamber shell 1 has high structural strength. This not only facilitates the stable positioning of the large-diameter nasal tube 2 and the small-diameter nasal tube 3, but also prevents damage to the oxygen supply chamber shell 1 when the large-diameter nasal tube 2 and the small-diameter nasal tube 3 are installed. This helps to further improve the reliability and applicability of the oxygen supply nasal plug structure that can switch between large and small nasal tubes.
[0029] like Figure 1 and Figure 2As shown, connecting lugs 15 are respectively provided on the left and right outer walls of the oxygen supply chamber shell 1, and an elastic band 16 connects the two connecting lugs 15. This helps to improve the stability and comfort of wearing, thereby helping to further improve the applicability of the oxygen supply nasal plug structure.
[0030] Soft silicone sheets are attached to the inner wall of the oxygen supply chamber shell 1 and the inner wall of the connecting lug 15, respectively, and a soft cloth cover is fitted onto the elastic band 16. This further improves the wearing comfort and thus enhances the applicability of the oxygen supply nasal plug structure.
[0031] like Figures 3 to 7 As shown, in actual use, a small-diameter nasal tube 3 can be installed on the left and a large-diameter nasal tube 2 on the right, or a large-diameter nasal tube 2 on the left and a small-diameter nasal tube 3 on the right, or both large-diameter nasal tubes 2 can be installed. This can meet various usage needs and completely solve all the technical problems mentioned in the background art. Therefore, this oxygen supply nasal plug structure that can switch between large and small nasal tubes can facilitate the selection of an oxygen tube of appropriate diameter according to different usage conditions. It can not only ensure that the examination or treatment of patients can be completed smoothly in various usage conditions, but also effectively ensure sufficient oxygen supply in various usage conditions, thereby reducing the adverse effects on the treatment of related patients. Moreover, it can facilitate the selection of a suitable nostril for invasive endoscopic examinations according to the condition of the patient's nostrils, effectively solving the problems in related examinations.
[0032] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
