Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology and relates to a device for nasopharyngeal ventilation. Background Technology

[0002] A nasopharyngeal airway is an artificial airway inserted into the pharynx through the nostrils. Its main functions are to prevent the tongue from falling back and to reduce damage to the nasal mucosa during suctioning. It can be used for conscious patients and is a commonly used instrument in anesthesiology.

[0003] After a nasopharyngeal airway is inserted into the patient's nasal cavity, medical tape is used to secure the air delivery end of the nasopharyngeal airway to the patient's face. When this is done for an extended period, pressure sores or even open wounds often develop on the patient's lips. This is especially true when a gastric tube is inserted simultaneously, as the pressure and abrasion on the lips are even greater, leading to more severe pressure sores on the lip skin.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] Example 1

[0029] This embodiment provides a device for nasopharyngeal ventilation, including an airway body 1, an airbag 2, and a fixing component 3, for inserting into the patient's pharynx through the patient's nostrils to form an artificial airway.

[0030] like Figure 1 As shown, the airway body 1 includes an airway inlet connector 11, an airway outlet connector 12, and a tube body 13; the airway inlet connector 11 and the airway outlet connector 12 are respectively connected to the two ends of the tube body 13; the airway inlet connector 11 is provided with internal threads for connecting oxygen delivery connectors or other components; the end face of the air outlet 121 of the airway outlet connector 12 is inclined to the center line of the tube body 13 so that the end of the airway outlet connector 12 in the direction of insertion into the nasopharynx remains smooth, thereby reducing damage to the inner wall of the nasopharynx.

[0031] like Figure 1 As shown, the airbag 2 is a closed, inflated airbag located at one end of the tube 13 near the airway inlet connector 11. The airbag 2 is arranged around the tube 13 and includes a fixed end 21 and a supporting end 22. The fixed end 21 is fixed to the outer wall of the tube 13, and the supporting end 22 extends outward along the radial direction of the tube 13.

[0032] In some embodiments, such as Figure 1As shown, the length of the fixed end 21 is less than half the outer circumference of the airway outlet connector 12 to prevent the airbag 2 from blocking the other nostril.

[0033] In some embodiments, such as Figure 1 As shown, the support end 22 is butterfly-wing shaped, with an arc-shaped curved surface to increase the contact area with the patient's lips and thus reduce the pressure on the lip skin.

[0034] When using the nasopharyngeal ventilation device of this embodiment, after gradually inserting one end of the airway outlet connector 12 into the nasopharyngeal passage through the patient's nostril, check the position of the air outlet 12 of the airway outlet connector 12 through the oral cavity to ensure that the air outlet 121 of the airway outlet connector 12 faces the front of the patient, so as to ensure unobstructed passage between the nasopharyngeal ventilation device and the patient's trachea.

[0035] In some embodiments, such as Figure 1 As shown, the end faces of the airbag 2 and the air outlet 121 of the airway outlet connector 12 are respectively arranged on both sides of a longitudinal symmetrical plane of the tube body 13. This ensures that when the airway outlet connector 12 is inserted into the epipharynx and the end face of the air outlet 121 of the airway outlet connector 12 faces the front of the patient, the airbag 2 can be located above the patient's lips. This not only supports the airway inlet connector 11 but also provides flexible protection for the patient's lip skin, thereby preventing pressure sores from forming on the patient's lips.

[0036] In some embodiments, such as Figure 1 As shown, the fixing component 3 is used to fix the position between the airway outlet connector 12 and the patient's head. Optionally, the fixing component 3 includes medical adhesive tape, which can be used to fix the airway outlet connector 12 to the patient's facial skin; it can also be a medical bandage or other fixing component, which can be used to fix the airway outlet connector 12 to the back of the patient's neck.

[0037] For example, such as Figure 1 and Figure 2 As shown, the fixing component 3 includes two medical adhesive patches. One end of each medical adhesive patch is fixedly connected to both ends of the fixing end 21 of the airbag 2, and the other end is provided with an adhesive patch 31 for attaching to the patient's head and face for fixation.

[0038] Preferred, such as Figure 1 and Figure 2 As shown, the adhesive strips 31 and the airbag 2 are respectively arranged on both sides of the fixing component 3. After the ventilation body 1 is inserted into the designated position, the adhesive strips 31 on both sides are peeled off and folded in half to make the adhesive side face the skin to fix the airway outlet connector 12. The folded fixing allows the fixing component 3 to wrap around the airway outlet connector 12 before being attached to the skin, resulting in a more stable fixation effect.

[0039] Example 2

[0040] The device for nasopharyngeal ventilation in this embodiment differs from that in Embodiment 1 in that the airbag 2 is detachably connected to the airway body 1.

[0041] In order to avoid the airbag 2 and the fixing component 3 affecting the insertion process of the airway body 1, the airbag 2 and the fixing component 3 in this embodiment are detachably connected to the airway body 1.

[0042] In some embodiments, such as Figure 2 As shown, the device for nasopharyngeal ventilation also includes a first connector 4, through which the cuff 2 and the airway body 1 are detachably connected. One end of the first connector 4 is fixedly connected to the fixed end 21 of the cuff 2, and the other end is provided with a fitting part 41 that matches the outer diameter of the airway outlet connector 12. The fitting part 41 can fit against the outer periphery of the tube body 13 to connect the cuff 2 and the airway body 1.

[0043] For example, the first connector 4 is an arc-shaped strip made of medical plastic, or it can be a patting plate with a built-in shape memory alloy.

[0044] Before the nasopharyngeal ventilation device of this embodiment is inserted into the nasal cavity, the airbag 2, the fixing component 3 and the first connector 4, which are fixed as one unit, are removed from the airway body 1. After the airway body 1 is inserted into the predetermined position, the fitting part 41 of the first connector 4 is fitted to the outer periphery of the airway outlet connector 12 so that the airbag 2 is located above the patient's lips. Finally, the airway body 1 is fixed by the fixing component 3.

[0045] Example 3

[0046] The device for nasopharyngeal ventilation in this embodiment differs from those in embodiments 1 and 2 in that the two air bladders 2 are detachably connected to the airway body 1.

[0047] Considering that in some cases a gastric tube needs to be inserted through another airway body 1 into the patient's other nasal cavity, such as Figure 3 As shown, the nasopharyngeal ventilation device of this embodiment includes two sets of airbags 2 and first connectors 4 arranged side by side on a fixing member 3. The distance between the center lines of the two first connectors 4 matches the distance between the two nostrils of the human body. When the patient needs to insert the airway body 1 into both nasal cavities, the two first connectors 4 can be conveniently fitted to the outer periphery of the two airway outlet connectors 12 respectively, and then the two airway bodies 1 are fixed together by the fixing member 3. Thus, an airbag 2 is provided for support below the two airway inlet connectors 11, which can provide flexible protection for the skin on both sides of the patient's lips. The operation is convenient and simple.

[0048] When a patient's nasal structure is not suitable for simultaneous insertion of two airway bodies 1, a gastric tube must be inserted directly into only the other nasal cavity. Since the outer diameter of the gastric tube is smaller than the outer diameter of the airway outlet connector 12, to avoid pressure injury to the patient's lips, such as... Figure 3 As shown, the device for nasopharyngeal ventilation in this embodiment also includes a filling element 5.

[0049] like Figure 3 As shown, the filler 5 includes a second connector 51 and a gasket 52. One end of the second connector 51 is fixed between the two first connectors 4, and the other end is fixedly connected to one end of the gasket 52. The gasket 52 is a deformable soft material with a length the same as the arc length of the first connector 4. It is used to fill the space between the gastric tube and the first connector 4 so that the air bladder 2 on the other side of the first connector 4 also provides support and protection.

[0050] In some embodiments, such as Figure 3 As shown, the second connector 51 is a flexible sheet that allows the gasket 52 to be positioned on either side so as to fill the first connector 4 on either side.

[0051] In some embodiments, the second connector 51 can be removed from the first connector 4. For example, the second connector 51 is made of medical non-woven fabric. When both nostrils need to be inserted into the nasopharyngeal passage, the second connector 51 can be torn off from the first connector 4, making the use of the nasopharyngeal ventilation device more flexible and convenient.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
