The technical solution of the utility model is further described below in conjunction with Figures 2-5.

Example 1

A nasal catheter with a pressure sore prevention function, see Figures 2-3, includes a nasal tube 1, an airway tube 2 and an intubation tube 3. An airway cavity 11 is provided in the nasal tube 1; at least one through hole 12 penetrating to the airway cavity 11 is provided on the nasal tube 1. In the present embodiment, one through hole 12 is provided, which is located at one end of the nasal tube 1. When assembled, the airway tube 2 is connected to the airway cavity 11 through the through hole 12. Specifically, the airway tube 2 can be plugged into the through hole 12 in a plug-in manner to achieve its connection with the nasal tube 1; the other end of the nasal tube 1 is blocked. There are two intubations 3, which are arranged side by side on the outer wall of the nasal tube 1 and whose inner cavities are connected to the airway cavity 11. When worn, the two intubations 3 are correspondingly inserted into the patient's nostrils to deliver oxygen to the patient.

An elastic connection frame 4 is provided on the side of the nasal tube 1 on the same side as the cannula 3 and above the cannula 3. The shape of the elastic connection frame 4 is adapted to the shape of the patient's cheek and/or nose; a first bonding surface 51 is provided at the bottom of the elastic connection frame 4, and a second bonding surface 61 is provided at the bottom of the nasal tube 1. When worn, the nasal tube 1 is bonded to the patient's upper lip through the first bonding surface 51, and the elastic connection frame 4 is bonded to the cheek and/or nose, thereby ensuring the wearing reliability of the nasal catheter. In addition, the shape of the elastic connection frame 4 is set to be adapted to the shape of the patient's cheek and/or nose, so that the elastic connection frame 4 can be limited and matched with the cheek and/or nose, thereby further improving its wearing reliability and stability.

The above-mentioned nasal catheter of this embodiment realizes reliable and stable wearing of the nasal catheter by providing an elastic connection frame 4 and a first bonding surface 51 and a second bonding surface 61, thereby avoiding the problem of pressure sores caused by the hanging rope exerting pressure on the patient's face and upper ear edge after the existing nasal catheter is worn and tightened.

In this embodiment, the nasal congestion tube 1, the cannula 3 and the elastic connection frame 4 are an integrally formed structure. When it is needed, the nasal cannula can be directly worn, which is convenient to use.

In practice, since the sizes of noses and cheeks of different patients are different, a variety of universal sizes can be manufactured so that the elastic connecting frame 4 can adapt to patients with noses and cheeks of different sizes.

In this embodiment, referring to FIG. 3 , the elastic connection frame 4 includes a nose frame 41 and a cheek frame 42. The two ends of the nose frame 41 are respectively connected to the nasal tube 1 and the cheek frame 42. The shape of the nose frame 41 is adapted to the patient's nose bridge, and the cheek frame 42 is adapted to the patient's cheek. The bottoms of the nose frame 41 and the cheek frame 42 are both provided with the above-mentioned first bonding surface 51. Therefore, when worn, the nose frame 41 and the cheek frame 42 are used for limiting cooperation with the face and the bonding force of the first bonding surface 51, so that the nasal catheter is finally firmly worn on the patient's face.

In this embodiment, referring to FIG. 3 , the top projection of the nasal tube 1 , the nose bridge skeleton 41 and the cheek skeleton 42 is in an I-shape.

Example 2

The present embodiment provides a nasal catheter with a pressure sore prevention function. Most of the structures of the nasal catheter are the same as those of the nasal catheter in Embodiment 1, except that the nasal tube 1 in the present embodiment is detachably connected to the elastic connecting frame 4, that is, the nasal tube 1 is detachably connected to the end of the nasal tube 1 on the nose bridge frame 41.

Specifically, referring to Fig. 4-Fig. 5, the nasal tube 1 is provided with a side plug-in slot 13 and a top plug-in slot 14, which are interconnected and have an L-shaped cross-section. The end of the side plug-in slot 13 away from the top plug-in slot 14 passes through the side of the nasal tube 1 on which the plug-in tube 3 is provided, and the end of the top plug-in slot 14 away from the side plug-in slot 13 passes through the top of the nasal tube 1. A plug-in portion 411 is provided at the end of the nose bridge frame 41 close to the nasal tube 1, and a button 412 is provided on the plug-in portion 411 for limiting the top plug-in slot 14. A bending portion 413 is provided on the other side of the plug-in portion 411 opposite to the button 412, and the distance between the top surface of the button 412 and the bottom surface of the bending portion 413 is greater than the size of the notch of the side plug-in slot 13. When assembling the nasal plug tube 1 and the nose bridge frame 41, the plug-in portion 411 on the nose bridge frame 41 is inserted into the side plug-in slot 13. Since the distance between the top surface of the button 412 and the bottom surface of the bending portion 413 is larger than the size of the notch of the side plug-in slot 13, the bending portion 413 is elastically deformed and bent. When the plug-in portion 411 is inserted into the bottom of the side plug-in slot 13, under the action of the elastic force of the bending portion 413, the button 412 is snapped upward into the top plug-in slot 14, thereby realizing the plug-in between the nasal plug tube 1 and the nose bridge frame 41.

In this embodiment, the nasal tube 1 is detachably connected to the elastic connection frame 4, so that the nasal tube 1 can be plugged with elastic connection frames 4 of different sizes as needed, so that the nasal tube 1 can be adapted to patients with different face sizes, thereby improving the applicability of the nasal catheter. In addition, after the elastic connection frame 4 is removed from the nasal tube 1, the nasal tube 1 can also be used in a traditional wearing manner.

In this embodiment, in order to facilitate the assembly and disassembly between the nasal tube 1 and the elastic connection frame 4, the button 412 and

The bending portion 413 has an arc top surface, that is, the corners are rounded.

Example 3

This embodiment provides a nasal catheter with a pressure sore prevention function, and the nasal catheter may be the nasal catheter of Embodiment 1 or Embodiment 2.

In this embodiment, a nasal congestion tube 1 with better anti-pressure sore function is further provided.

Specifically, the bottom of the nasal tube 1 is provided with a first foam dressing 5 or a first hydrocolloid auxiliary material. In this embodiment, the bottom of the nasal tube 1 is the first foam dressing 5, and the bottom surface of the first foam dressing 5 is the first bonding surface 51. By providing a foam dressing at the bottom of the nasal tube 1, it is not only ensured that the nasal tube 1 can be bonded to the upper lip of the patient, but also can effectively alleviate the pressure sore problem caused by the long-term pressure of the nasal tube 1 on the upper lip, further improving the anti-pressure sore effect.

The bottom of the elastic connection frame 4 is provided with a second hydrocolloid auxiliary material 6, and the bottom surface of the second hydrocolloid auxiliary material 6 is the above-mentioned second bonding surface 61. By preferably arranging the hydrocolloid auxiliary material at the bottom of the elastic connection frame 4, it is not only ensured that the elastic connection frame 4 can be bonded to the patient's face, but also can effectively alleviate the pressure sore problem caused by the long-term downward pressure of the elastic connection frame 4, and further improve the anti-pressure sore effect; in addition, since the second hydrocolloid auxiliary material 6 has plasticity, it is convenient to arrange it at the bottom of the elastic connection frame 4 with a certain shape.

In this embodiment, the first foam dressing 5 is bonded to the bottom of the elastic connecting frame 4, and the second hydrocolloid auxiliary material 6 is bonded to the bottom of the nasal tube 1. In this way, when the bonding effect of the first foam dressing 5 and/or the second hydrocolloid auxiliary material 6 is reduced, they can be torn off and new auxiliary materials can be pasted on to ensure the wearing effect of the nasal catheter.
