Description

Technical Field

[0001] The utility model belongs to the technical field of nasopharyngeal airway fixing equipment, in particular to a nasopharyngeal airway fixing device. Background Art

[0002] A nasopharyngeal airway is an artificial airway placed through the nostrils into the patient's pharynx. It ensures smooth breathing, prevents the tongue from falling back, and reduces damage to the nasal mucosa caused by suctioning. It is often used in awake patients after clinical surgery. Some surgeries require the patient to retain a nasopharyngeal airway to help maintain airway patency.

[0003] However, patients often find the foreign body sensation of the nasopharyngeal airway unbearable, becoming restless and frequently changing their posture, which can cause the nasopharyngeal airway to shift. To prevent the nasopharyngeal airway from shifting or falling, medical staff currently use tape or rope to secure it to the patient's head and face. However, prolonged fixation can easily cause the tape to shift or detach, resulting in a loose nasopharyngeal airway fixation and affecting the patient's normal use.

[0004] The utility model patent with application number 201721124320.3 discloses a nasopharyngeal airway fixing belt, which further fixes the position of the nasopharyngeal airway and avoids the risk of the nasopharyngeal airway falling out or sliding deep into the respiratory tract during use. However, the through-holes opened on the oval fixing plate of the patent are facing forward and have a large aperture. It does not take into account that after the nasopharyngeal airway is inserted into the user's nasopharynx, the part of the pipe exposed to the outside world actually extends downward, and thus it is impossible to fix the pipe exposed to the nose, and the problem of the nasopharyngeal airway not being firmly fixed still exists; in addition, the patent only makes settings for the nose, and does not take into account the discomfort caused by the patient's face being strangled by the connecting belt for a long time, resulting in low wearing comfort. Therefore, there is an urgent need to provide a fixing device that can solve the above problems. Utility Model Content

The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0028] Example 1:

[0029] See attached Figure 1A nasopharyngeal airway fixation device comprises a fixed main frame 1 and a flexible band 2. The fixed main frame 1 has a nasal fixation component on its inner side, and a sliding bracket 3 is fixed to the front side of the fixed main frame 1. The sliding bracket 3 is provided with a nasopharyngeal fixation component 4 and two lateral fixation components 5. The nasopharyngeal fixation component 4 is located in the center of the sliding bracket 3. The nasopharyngeal fixation component 4 includes at least an adjustment clamp 41 for adjusting the size to fix nasopharyngeal airways of different sizes. The two lateral fixation components 5 are symmetrically arranged and slidably connected to the left and right sides of the sliding bracket 3 respectively. The two lateral fixation components 5 are used to fix the left and right sides of the user's face. The left and right ends of the flexible band 2 are each connected to a lateral fixation component 5 for fixing the back of the user's head. As can be seen from the above structure, the fixed main frame 1 serves as a base for connecting the sliding bracket 3. The sliding bracket 3 can be installed on the front side of the fixed main frame 1 via a connecting member. In addition, a nasal fitting component that can fit the nose is provided on the inner side of the fixed main frame 1. The left and right sides of the sliding bracket 3 are each slidably connected to a lateral fixing component 5, and the two lateral fixing components 5 have the same structure and symmetrical shape. The two lateral fixing components 5 are used to fix the left and right sides of the user's face, which can further enhance the overall fixing effect of the device and prevent the device from shifting, thereby affecting the fixing effect of the nasopharyngeal airway. A nasopharyngeal fixing component 4 is also provided in the center of the sliding bracket 3. The nasopharyngeal fixing component 4 includes at least an adjustment wire clamp 41. The adjustment wire clamp 41 can be a buckle-type wire clamp in the prior art, such as the Lianyang LY0810 buckle-type wire clamp. By adjusting the degree of tightening itself to adapt to nasopharyngeal airways of different sizes, the part of the nasopharyngeal airway that extends out of the user's nose is fixed to ensure the fixing effect of the nasopharyngeal airway. The flexible belt 2 has a certain degree of deformation ability. The left and right ends of the flexible belt 2 are respectively connected to a lateral fixing component 5, which is used to fit and fix the back of the user's head after the device is worn, ensuring wearing comfort and fixing effect.

[0030] Example 2:

[0031] See attached Figures 1 to 3Based on the first embodiment, the sliding bracket 3 includes two engaging portions 31; the two engaging portions 31 are symmetrically arranged on the left and right sides of the sliding bracket 3; the engaging portions 31 have a plurality of engaging grooves 311 arranged in sequence along the horizontal direction; each lateral fixing assembly 5 is provided with an engaging member 51 for slidingly connecting with the corresponding engaging portion 31; the engaging member 51 includes a claw portion and a pressing portion; the claw portion is used to engage with the engaging groove 311 on the engaging portion 31 to lock the position of the engaging member 51; the pressing portion is used to release the engaging state of the engaging member 51. As can be seen from the above structure, the two engaging portions 31 of the sliding bracket 3 are respectively slidably connected to the engaging members 51 of the corresponding lateral fixing assembly 5, and are used to fix or release the relative position between the lateral fixing assembly 5 and the sliding bracket 3 by engaging or disengaging the engaging members 51, thereby adjusting the position fixed to the user's face to improve wearing comfort. The specific engagement principle is related to the existing sliding buckle technology, so it will not be described in detail in this utility model.

[0032] The lateral fixing assembly 5 also includes a lateral bracket 52 and a lateral fixing pad 53; the front end of the lateral bracket 52 is connected to the outer wall of the clamping member 51 located on the front side of the sliding bracket 3; the lateral fixing pad 53 is arranged on the inner side of the lateral bracket 52, and the lateral fixing pad 53 is used to fit the user's face. As can be seen from the above structure, the utility model arranges the lateral bracket 52 on the front side of the sliding bracket 3, and the front end of the lateral bracket 52 is connected to the outer wall of the clamping member 51 located on the front side of the sliding bracket 3. This arrangement can ensure that after the device is worn, the two lateral fixing pads 53 are tightly attached to the two sides of the user's face due to the tension of the flexible belt, thereby fixing the patient's face. At this time, the two clamping members 51 corresponding to the two lateral fixing pads 53 also provide a backward pressing force to the left and right ends of the sliding bracket 3 at the same time, thereby achieving the position fixation of the nasopharyngeal fixing assembly 4 set in the center of the sliding bracket 3, ensuring that the nasopharyngeal fixing assembly 4 will not easily shift after the device is worn, and ultimately improving the fixation effect of the nasopharyngeal airway.

[0033] The lateral bracket 52 includes a first support portion 521 and a second support portion 522. The first support portion 521 extends upwardly at an angle relative to the second support portion 522 and is used to provide support for the lateral fixing pad 53. The second support portion 522 of each lateral bracket 52 is used to connect to the left or right end of the flexible belt 2, which is closer to the side. As can be seen from the above structure, the lateral bracket 52 includes a first support portion 521 and a second support portion 522. The first support portion 521 extends upwardly at an angle relative to the second support portion 522. As a branch of the lateral bracket 52, the first support portion 521 can provide additional support for the lateral fixing pad 53, reducing the displacement of the lateral fixing pad 53 caused by the opening and closing of the patient's mouth when wearing the device, thereby improving the device's fixing effect. The second support portion 522 is arranged horizontally, and its shape and thickness can be adaptively adjusted according to the fixing requirements. It is used to connect to the left or right end of the flexible belt 2, which is closer to the side. Moreover, after the device is worn, the second support portion 522 , because it is connected to the flexible belt 2 , can also provide a certain pressing force for the lateral fixing pad 53 , thereby ensuring the fixing effect of the device after being worn.

[0034] The flexible belt 2 is provided with an elastic connector 21 at each of its left and right ends; a connecting ring 5221 is provided at the end of each second support portion 522; the elastic connectors 21 correspond one-to-one with the connecting rings 5221; and the front end of each elastic connector 21 is connected to the corresponding connecting ring 5221. As can be seen from the above structure, since the elastic connectors 21 themselves have a strong elastic force, the lateral supports 52 are connected to the flexible belt 2 via the elastic connectors 21. This not only makes the device more applicable to patients with different head circumferences, but also reduces the tension on the flexible belt 2, which not only improves the wearing comfort of the device but also prevents the flexible belt 2 from breaking or curling, thereby increasing its service life.

[0035] The elastic connecting member 21 is an elastic band. As can be seen from the above structure, the elastic band is highly elastic and very durable, which can increase the service life of the device.

[0036] The lateral fixing pad 53 is a foam pad. As can be seen from the above structure, the foam pad is soft and breathable. Setting the lateral fixing pad 53 as a foam pad can be skin-friendly and permeable, ensuring the comfort of wearing the device and preventing the lateral fixing pad 53 from crushing the user's skin.

[0037] Example 3:

[0038] See attached Figures 1 to 3. On the basis of the second embodiment, the sliding bracket 3 is further provided with two lugs 32, and the two lugs 32 are symmetrically arranged in the center of the sliding bracket 3; the lugs 32 protrude to the side away from the outer side of the sliding bracket 3; the nasopharyngeal fixing assembly 4 also includes a wire clamp connector 42; the upper end of the wire clamp connector 42 is clamped between the two lugs 32; the adjusting wire clamp 41 includes a wire clamp base plate and a wire clamp clamping portion; the wire clamp base plate is connected to the lower end of the wire clamp connector 42; the wire clamp clamping portion is used to surround the outer side of the outer wall of the nasopharyngeal airway and clamp the nasopharyngeal airway. It can be seen from the above structure that the two lugs 32 are respectively fixedly connected to the left and right side walls of the wire clamp connector 42 at the upper end, used to provide support for the wire clamp connector 42, and the lower end of the wire clamp connector 42 is used to be fixedly connected to one side wall of the wire clamp base plate of the adjusting wire clamp 41. Specifically, the type of adjustment wire clamp 41 can be an existing LY buckle wire clamp, and a wire clamp clamping part that can be engaged or contact engaged is provided on the inner side surface of the wire clamp base plate. When in use, it is only necessary to wrap the wire clamp clamping part around the outer side of the outer wall of the nasopharyngeal airway, and then engage and tighten it to complete the fixation of the nasopharyngeal airway. When releasing the fixation, it is only necessary to release the engagement, which is easy to operate.

[0039] The nose fixing component is a nose fixing pad 6; the nose fixing pad 6 is provided in the center of the inner side of the fixed main frame 1. As can be seen from the above structure, the nose fixing pad 6 is provided in the center of the inner side of the fixed main frame 1. The nose fixing pad 6 can be specifically designed to fit the shape of the nose to ensure the correct wearing position of the device. The nose fixing pad 6 is made of soft and breathable material, which is soft and skin-friendly, and does not hurt the user's skin while fixing the nose.

[0040] The width of the flexible belt 2 is 6-16 cm. As can be seen from the above structure, the flexible belt 2 is widened to improve the wearing comfort of the user. The width of the flexible belt 2 can be adaptively adjusted according to the elastic force of the elastic connector 21, and can be preferably 8 cm, 12 cm and 14 cm.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
