Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a nasal oxygen tube that prevents pressure injury. Background Technology

[0002] A nasal cannula is a medical device used to deliver oxygen, typically to patients experiencing breathing difficulties or requiring oxygen therapy. It is a flexible tube with one end connected to an oxygen source and the other end inserted through the patient's nostril to deliver oxygen.

[0003] It is important to note that because of the high oxygen flow rate during oxygen delivery, the nasal cannula is prone to displacement. Therefore, clinicians often use adhesive tape or other fixatives to firmly secure the nasal cannula to the patient's face to prevent displacement. However, prolonged use can easily cause pressure damage to the facial skin. Currently, in clinical practice, gauze, tissues, pressure-relieving patches, or hydrogel are typically placed under the nasal cannula to reduce pressure on the patient's face. However, this method has the following drawbacks:

[0004] 1. When patients use gauze or tissues, the rough surfaces of gauze and tissues can cause friction to the patient's skin if the patient has wounds or fragile skin, leading to discomfort.

[0005] 2. When patients use tension-reducing dressings or hydrogels, on the one hand, when changing the adhesive layer of the tension-reducing dressing, the patient's facial skin needs to be pulled. On the other hand, the patient's face is covered by the tension-reducing dressing and hydrogel adhesive parts, which can easily cause stuffiness, redness and other symptoms; the comfort of use is low.

[0006] Therefore, designing a nasal oxygen tube that can prevent pressure injury and solve the above problems is a technical issue that needs to be addressed. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this invention is to provide a pressure-resistant nasal oxygen tube that solves the issues of existing nasal oxygen tubes requiring fixation to the patient's face, causing pressure injuries to the patient's skin, resulting in pressure damage and low comfort during use.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: it includes a headband frame, earmuff bodies fixedly disposed at the bottom of both ends of the headband frame, an adjustment tube assembly hinged to the outer surfaces of the two earmuff bodies, and a disposable nasal oxygen tube detachably connected to the adjustment tube assembly; the adjustment tube assembly includes a connecting post hinged to the outer surface of the earmuff bodies, a bent tube fixedly disposed at one end of the connecting post, and a plurality of nasal oxygen tube fixing clips slidably disposed on the bent tube; the inner surface of the connecting post and the outer surface of the supporting ring are hinged together by a spherical hinge; each of the plurality of nasal oxygen tube fixing clips includes a connecting collar movably sleeved on the outer peripheral wall of the bent tube and a limiting U-shaped buckle fixedly disposed on the outer peripheral wall of the connecting collar.

[0009] Furthermore, the bend is made of carbon steel.

[0010] Furthermore, the length of the bent pipe ranges from 6cm to 9cm.

[0011] Furthermore, both the inner circumferential wall of the connecting collar and the inner sidewall of the limiting U-shaped buckle are provided with anti-slip stripes.

[0012] Furthermore, the inner side of the earcup is provided with a covering gasket along the outer edge of the earcup in a circumferential manner.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model is provided with a head frame, an earmuff body, an adjustment tube assembly hinged to the outside of the earmuff body, and a disposable nasal oxygen tube detachably connected to the adjustment tube. By bending and adjusting the placement shape of the bent tube, it is kept suspended and away from the face, so that the disposable nasal oxygen tube is away from the face and avoids pressure injury to the patient's face.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] See Figure 1-2As shown, it includes a headband frame 1, earmuff bodies 2 fixedly disposed at the bottom of both ends of the headband frame 1, an adjustment tube 3 assembly hinged to the outer side of the two earmuff bodies 2, and a disposable nasal oxygen tube 4 detachably connected to the adjustment tube 3 assembly; the headband frame 1 is an elastic frame that can be widened by pulling it to both sides to adapt to users with different head sizes. The headband frame 1 has a predetermined clamping force to keep the headband frame 1 on the user's head and to keep the earmuff bodies 2 on the user's ears.

[0024] Ideally, the diameter of the earmuff outer cover is larger than the size of a typical adult ear, so that it can completely cover the user's ear and increase patient comfort. In this embodiment, a covering gasket 21 is provided on the inner side of the earmuff body 2 along the outer edge of the earmuff body 2 in a circumferential manner.

[0025] The adjustment tube 3 assembly includes a connecting post 31 hinged to the outer side of the earmuff body 2, a bent tube 32 fixed to one end of the connecting post 31, and a plurality of nasal oxygen tube fixing clips 33 slidably disposed on the bent tube 32; the inner side of the connecting post 31 is hinged to the outer side of the supporting ring through a spherical hinge; the connecting post 31 can be adjusted in multiple directions through the spherical hinge, so that the adjustment tube 3 assembly can be raised to the patient's head as needed, so as to be closer to or further away from the patient's face. By increasing the friction coefficient of the spherical hinge, the connecting post 31 is prevented from arbitrarily changing its position and the relative position is maintained.

[0026] Each of the aforementioned nasal oxygen tube fixing clips 33 includes a connecting collar 331 sleeved on the outer peripheral wall of the curved tube 32 and a limiting U-shaped buckle 332 fixedly disposed on the outer peripheral wall of the connecting collar 331.

[0027] Furthermore, in this embodiment, the limiting U-shaped buckle 332, when in use, the opening range increases after the U-shaped opening is deformed by force, which facilitates the passage of the disposable nasal oxygen tube 4. When the disposable nasal oxygen tube 4 is locked in the limiting U-shaped buckle 332, the opening is restored and wraps around the disposable nasal oxygen tube 4, thus fixing the disposable nasal oxygen tube 4.

[0028] In order to increase the friction between the connecting collar 331 and the bend 32, and between the limiting U-shaped buckle 332 and the disposable nasal oxygen tube 4, this embodiment provides anti-slip stripes 333 on the inner peripheral wall of the connecting collar 331 and the inner side wall of the limiting U-shaped buckle 332.

[0029] The bend 32 is made of carbon steel and can withstand multiple free bending by the user while maintaining its bent shape.

[0030] The face width of a typical adult is 12-18cm. In this embodiment, the length of the two curved tubes 32 on the left and right sides is set to be 6cm-9cm.

[0031] The working principle is roughly as follows:

[0032] In use, the device is worn on the patient's head using the headband 1. The bent tube 32 is bent and adjusted to be arc-shaped or irregularly shaped, maintaining a certain distance from the face. The disposable nasal oxygen tube 4 is then fixed to the outside of the bent tube 32 with the nasal oxygen tube fixing clip 33, maintaining the same curvature as the bent tube 32. The disposable nasal oxygen tube 4 is then inserted into the patient's nasal cavity (to prevent the oxygen tube from falling off, it can be fixed at the nasal position), so that the disposable nasal oxygen tube 4 is away from the face, suspended above the face, and avoids compressing the face.

[0033] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
