Abstract
Description
Technical Field
[0001] The utility model relates to medical equipment, in particular to a nasal catheter for preventing pressure sores. Background Art
[0002] Nasal cannula: A slender rubber or plastic tube with openings at the tip and sides, inserted into the nasal vestibule. It is currently a widely used oxygen delivery device in hospitals at all levels in China. Bilateral nasal cannulae can also be used, inserted simultaneously into both nostrils. This method offers good compliance, allows for shallow insertion, and is easily accepted by patients.
[0003] After searching, it was found that the application number is CN202121108178.X for a nasal catheter device for respiratory monitoring of newborns and infants. The content is as follows: The utility model relates to a nasal catheter device for respiratory monitoring of newborns and infants, including a bacteria filter device, an exhaled air collection tube, an oxygen catheter, and a nasal catheter connecting tube. The bacteria filter device is arranged at the front of the oxygen catheter, the exhaled air collection tube is arranged in the middle of the oxygen catheter, the nasal catheter connecting tube is arranged at the rear of the oxygen catheter, the oxygen catheter and the nasal catheter connecting tube are connected, and two nasal catheters for insertion into the nasal cavity are arranged on the nasal catheter connecting tube. The catheter connecting tube between the two nasal catheters is provided with a corrugated telescopic tube section. The bacteria filter device can filter a small amount of bacteria in the oxygen. When exhaling, the exhaled air is transported to the connected carbon dioxide analyzer through the exhaled air collection tube. While the conscious patient is inhaling oxygen through the nose, the patient's breathing can be monitored. The structure is simple, safe and reliable. The distance between the two nasal catheters can be adjusted by the extension and contraction of the corrugated telescopic tube section. Children with different nose sizes can also use the same model of nasal catheter. It has a wide range of applications and is easy to use.
[0004] Disposable nasal cannulas currently used in clinical practice can easily cause pressure sores in the nose and ears when used for a long time. Changing the material in these two locations to foam can effectively prevent pressure sores. There are two protrusions at the connection between the nasal cannula and the nose, which are inserted into the two nasal cavities respectively, to play the role of fixing and centralizing air supply. However, the patient's comfort will be reduced. Is it possible to set up a device here that does not require protrusions, can centralize air supply, and can be easily fixed? Utility Model Content

[0039] In this embodiment: it also includes a nose clip air delivery mechanism 4 installed at one end of the connecting hose 11;
[0040] The nose clip air delivery mechanism 4 includes a nose clip 41 installed at the end of the connecting hose 11, and a plurality of adjustment buckles 42 for limiting are fitted on the surface of the nose clip 41.
[0041] The nose clip 41 and the adjustment buckle 42 used play a role in binding the corresponding air supply stage.
[0042] In this embodiment, the edge of the adjusting buckle 42 is evenly surrounded by a designated surface edge of the adjusting buckle 42 , and the output end of the communicating hose 11 corresponds to the middle of the nose clip 41 .
[0043] The gas entry seal is achieved by the use of the adjusting buckle 42 and the corresponding connecting hose 11 and the nose clip 41 .
[0044] In this embodiment, a concave sliding mechanism 3 is installed on the side of the connecting hose 11. The concave sliding mechanism 3 includes a fitting sleeve bracket 31 installed on the outer wall of the connecting hose 11. The fitting sleeve bracket 31 is provided with a buffering clamping arrangement of an elastic structure.
[0045] A sliding clamping rubber 32 is installed at the bottom of the fitting sleeve bracket 31 .
[0046] The connection state of the fitting sleeve bracket 31 and the sliding clamping rubber 32 is changed according to the position of the corresponding sliding clamping rubber 32.
[0047] In this embodiment: an ear-fitting buffer mechanism 2 is fitted on the bottom of the fitting sleeve bracket 31, and the ear-fitting buffer mechanism 2 includes a curved connector 21 installed on the side wall of the end of the fitting sleeve bracket 31, and a curved rubber block 22 is installed at the end position of the curved connector 21, and curved toggle blocks 23 are symmetrically installed at both ends of the curved rubber block 22.
[0048] The arc-shaped connector 21 and the arc-shaped rubber block 22 are used to bind to the specific patient.
[0049] In this embodiment, a concave sliding groove 24 is provided at the bottom of the sliding clamping rubber 32 . The bottom of the concave sliding groove 24 is slidably arranged with the outer wall of the designated connecting hose 11 , and one end of the connecting hose 11 is elastically fitted to the patient's cheek.
[0050] The position change is achieved by the adopted connecting hose 11 and the specific groove structure of the concave sliding groove 24 .
[0051] In this embodiment, the sliding clamping rubbers 32 are symmetrically arranged on the surface of the communicating hose 11 , and the surface of the communicating hose 11 is symmetrically arranged with the designated clamping structure.
[0052] Combine them.
[0053] When using: Step 1: Fit and clamp the designated nose clip 41;
[0054] The primary technology is to use the tube of the connecting hose 11 to achieve elastic fit with the patient's nose after being buckled with the adjustable buckle 42, and to achieve fit and clamping according to the clamping section of the nose clip 41 using a concave structure. At this time, the nose tip is attached to one end of the patient for clamping. After the nose clip 41 is expanded, it is clamped according to the clamping structure of the adjustable buckle 42. The corresponding nose clip 41 is used to achieve fit, and the elastic structure of the nose clip 41 is used to achieve elastic binding. Specifically, the gas is bound around the tube state of the connecting hose 11. After binding, the binding structure of the nose clip 41 is expanded to enter. In this way, the gas is discharged after being delivered. After being discharged, it is directly absorbed by the patient's nasal cavity along the state of the nose clip 41.
[0055] Step 2: Fit on both sides of the patient's cheeks;
[0056] At this time, the user slides the connecting hose 11 back and forth in a straight line, and after reaching a specific position by utilizing the position of the concave sliding groove 24, the sliding clamping rubber 32 on the pipe-passing stage of the connecting hose 11 is attached to the corresponding curved rubber block 22 according to one end of the concave sliding groove 24. With the elastic fit of the corresponding sliding clamping rubber 32, the connecting hose 11 is attached to the patient's cheek and fixed. Finally, the curved rubber block 22 is slid back and forth. When the connecting hose 11 reaches a suitable position with the patient's cheek, the elastic force of the fitting sleeve bracket 31 is used to tighten the fitting sleeve bracket 31 to reduce the sliding effect in this area.
[0057] Step 3: Final oxygen administration;
[0058] This process solves the problem of the uncomfortable insertion of the two independent tube heads of a conventional nasal suction tube. It is based on the fact that the nose clip 41 fits the patient's nasal cavity well and is bound by the corresponding sliding clamping rubber 32 to improve the effect of the nasal tube air delivery stage.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
