Detailed Description

The utility model will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it will be understood that various changes or modifications may be made by those skilled in the art after reading the teachings of the utility model, and such equivalents are intended to fall within the scope of the utility model as defined herein.

The utility model relates to a nasal cannula fixing device which is mainly used for fixing a nasal cannula and preventing an indwelling gastric tube from moving in and falling out of a nasal cavity, and the main structure comprises a nasal cavity indwelling part 2 and a limiting part which are sleeved on an indwelling tube 1;

as shown in fig. 1 and 2 of the accompanying drawings, the nasal cavity retaining member 2 is in a cone shape, the nasal cavity retaining member 2 comprises two parts, the two parts are sleeved on the retaining tube 1 together, and the nasal cavity retaining member 2 needs to be fixed for preventing the two parts from being separated, so that the wide end of the nasal cavity retaining member 2 is provided with a connecting groove 7, a fixing ring 8 is arranged in the connecting groove 7, the fixing ring 8 has elastic force, the nasal cavity retaining member 2 of the two parts is fixedly sleeved on the retaining tube 1 together, and an anti-slip pad 6 is arranged in the tip of the nasal cavity retaining member 2, so that when the fixing ring 8 sleeves the two nasal cavity retaining members 2, the anti-slip pad 6 at the tip of the nasal cavity retaining member 2 is contacted with the retaining tube 1, and the nasal cavity retaining member 2 and the retaining tube 1 are prevented from sliding relatively through friction force.

The nasal cavity retaining member 2 and the retaining tube 1 are reduced to slide relatively, but in order to further limit the retaining tube 1, the limiting member is further arranged and comprises a limiting plate 3 and rope belts 4, the rope belts 4 are arranged on two sides of the limiting plate 3, limiting holes 5 are formed in the limiting plate 3, the rope belts 4 are worn on the head to fix the limiting plate 3 at the nose, and the nasal cavity retaining member 2 and the limiting holes 5 of the limiting plate 3 are matched to limit the retaining tube 1 to slide outside the nasal cavity. Since the nasal cavity indwelling member 2 is placed in the nasal cavity, the influence on the patient is reduced as much as possible, and the nasal cavity indwelling member 2 is provided with the ventilation hole 9, and the air is introduced into the nasal cavity of the patient through the ventilation hole 9.

Because the placement of the nasal cavity retention 2 within the nasal cavity in turn creates two embodiments, described separately below:

example 1:

as shown in fig. 1 and 3 of the drawings of the specification, the wide end of the nasal cavity retaining member 2 is located at the inner side of the nasal cavity, and the narrow end of the nasal cavity retaining member 2 is located at the outer side of the nasal cavity, because the contact surface of the two nasal cavity retaining members 2 is not a plane but an inclined surface, when the two nasal cavity retaining members 2 are sheathed together, the anti-slip pad 6 in the tip of the nasal cavity retaining member 2 acts on the retaining tube 1 to prevent relative slip between the two, but in order to further improve the limiting effect of the device on the retaining tube 1, the limiting hole 5 is a conical hole 10. When the indwelling tube 1 is pulled outwards, the tip of the nasal cavity indwelling piece 2 acts on the conical limiting hole 5, so that the more the indwelling tube 1 is pulled outwards, the larger the friction force of the anti-slip pad 6 in the tip of the nasal cavity indwelling piece 2 acts on the indwelling tube 1, so that the nasal cavity indwelling piece 2 and the indwelling tube 1 are limited together, and the indwelling tube 1 is not pulled out even if the patient pulls, but the more the two nasal cavity indwelling pieces 2 are pulled outwards, the more tightly the indwelling tube 1 is acted.

According to the above, since the anti-slip pad 6 inside the tip of the nasal cavity indwelling member 2 acts on the indwelling tube 1, when the position of the nasal cavity indwelling member 2 is installed and adjusted, since the friction force of the anti-slip pad 6 makes the adjustment inconvenient when the position of the nasal cavity indwelling member 2 is adjusted, further improvement is made: the tip of the nasal cavity detaining piece 2 is provided with a stop 11. When the nasal cavity indwelling members 2 are pushed into the nasal cavity, the two nasal cavity indwelling members 2 are spread by forceps, and then the positions of the nasal cavity indwelling members 2 are pushed and adjusted.

For the installation of the nasal cavity retention element 2 in embodiment 1, the two nasal cavity retention elements 2 are sleeved on the retention tube 1, then the fixing ring 8 is sleeved in the connecting groove 7, the two nasal cavity retention elements 2 are spread by acting on the stop block 11 through forceps, then the position of the nasal cavity retention element 2 is adjusted, then the limiting hole 5 of the limiting plate 3 is aligned with the nostril of the patient, and the rope belt 4 is sleeved on the head of the patient and fixed.

Example 2:

as shown in fig. 4 and 5 of the accompanying drawings, the narrow end of the nasal cavity retaining member 2 is located at the inner side of the nasal cavity, i.e. the wide end of the nasal cavity retaining member 2 is located at the outer side of the nasal cavity, which is more suitable for some common patients, the placing method is more suitable for the physiological structure of the nasal cavity of the human body, foreign body sensation and uncomfortable feeling of the patient are reduced, because the anti-slip pad 6 at the tip of the nasal cavity retaining member 2 is contacted with the retaining tube 1, the two are prevented from sliding relatively by friction force between the nasal cavity retaining member 2 and the retaining tube 1, and the effect of preventing sliding can be achieved to a certain extent, therefore, the wide end of the nasal cavity retaining member 2 is limited only by limiting the wide end of the nasal cavity retaining member 2, the limiting hole 5 is a through hole, and the limiting hole 5 is smaller than the diameter of the wide end of the nasal cavity retaining member 2. So that the wide end of the nasal cavity retaining member 2 is prevented from being pulled out by the limiting plate 3 after the rope 4 is taken on the patient.

Further improvement is made as described in example 1 because the friction of the anti-slip pad 6 makes adjustment inconvenient when adjusting the position of the nasal cavity stay 2: the wide end of the nasal cavity retaining member 2 is provided with a handle 12. The nasal cavity retaining member 2 is spread by pinching the handle 12 by hands or forceps, and then the position of the nasal cavity retaining member is finely adjusted.

In the use method of the embodiment 2, firstly, the two nasal cavity retaining members 2 are sleeved on the retaining tube 1, then the fixing ring 8 is sleeved in the connecting groove 7, the two nasal cavity retaining members 2 are spread by acting on the handle 12 through forceps, then the position of the nasal cavity retaining members 2 is adjusted, then the limiting holes 5 of the limiting plate 3 are aligned with nostrils of a patient, and the rope belt 4 is sleeved on the head of the patient and fixed.

To sum up, this device can be used for fixing nasal insertion indwelling gastric tube, can prevent to block up patient's trachea when indwelling tube 1 deviate from, leads to the patient to suffocate. The device can be used for a long time without frequent replacement, and can be replaced according to different conditions of patients, and the indwelling tube 1 can be safely and reliably fixed for paranoid patients or patients with frequent tube drawing conditions.
