[0049] The pressure sore prevention tracheal catheter 10 according to the utility model embodiment is described in detail below with reference to the drawings.

[0050] Referring to Figures 1 to 5 As shown in the figure, the pressure sore prevention tracheal catheter 10 according to the utility model embodiment comprises a tracheal catheter 10, a holder 20, a fixing piece 29 and a pressure relief protective sleeve 12.

[0051] The tracheal catheter 10 is provided with an air bag, and the tracheal catheter 10 is integrally connected with an inflation pipe 11 in the middle of the bottom surface, to inflate the air bag 13. That is, the inflation pipe 11 and the air bag 13 are in communication.

[0052] The holder 20 is adapted to be supported between the upper teeth and the lower teeth of a patient, to open the mouth of the patient, and the outer surface of the holder 20 is provided with a limiting groove 21 along the circumference thereof, to limit the upper teeth and the lower teeth of the patient, and the holder 20 is provided with a through hole 22, and the tracheal catheter 10 is arranged in the through hole 22.

[0053] The fixing piece 29 is arranged on the front side of the holder 20, to fix the position of the tracheal catheter 10 in the holder 20.

[0054] The pressure relief protective sleeve 12 is arranged on the outer surface of the tracheal catheter 10 and the inflation pipe 11, to reduce the pressure on the oral mucosa of the patient.

[0055] Based on the above, by designing the decompression protective sleeve 12, the tracheal catheter 10 can effectively reduce the pressure on the oral mucosa of the patient, thereby reducing the risk of oral mucosa damage or pressure sores caused by long-term intubation, and significantly improving the comfort of the patient. The design of the fixer 20 can be supported between the upper teeth and the lower teeth of the patient, and the teeth of the patient are limited by the limiting groove 21, which not only effectively expands the mouth of the patient, facilitates the insertion and fixation of the tracheal catheter 10, but also further ensures the stable position of the tracheal catheter 10 in the fixer 20, thereby reducing the possibility of catheter displacement or falling. The tracheal catheter 10 is integrally connected with the inflation tube 11 in the middle of the bottom surface, which enables the inflation and deflation of the air bag 13 on the tracheal catheter 10 after intubation to control the expansion degree of the air bag 13. The present application not only ensures the functionality of the catheter, but also pays attention to the safety experience of the patient, and reduces the discomfort and complications caused by intubation.

[0056] Advantageously, since the tracheal catheter 10 and the fixer 20 are detachable, when the support function of the fixer 20 is not needed in actual use, the fixer 20 can be detached, and the tracheal catheter 10 can be retained.

[0057] Preferably, in an embodiment of the present application, the bottom surface of the through hole 22 is provided with a groove 23, and the inflation tube 11 is arranged in the groove 23.

[0058] Therefore, since the inflation tube 11 is cleverly embedded in the groove 23, it is avoided that the inflation tube 11 directly protrudes from the surface of the tracheal catheter 10, so that the tracheal catheter 10 does not press the inflation tube 11, thereby affecting the smoothness of the internal passage.

[0059] Preferably, in an embodiment of the present application, the limiting groove 21 is provided with an inflatable pad 24, and the inflatable pad 24 extends along the length direction of the limiting groove 21.

[0060] Therefore, the soft material of the inflatable pad 24 can better adapt to the shape and size of the teeth of the patient, thereby reducing the direct pressure of the hard edge of the fixer 20 on the teeth of the patient, and significantly improving the comfort of the patient.

[0061] Preferably, in an embodiment of the present application, the surface of the inflatable pad 24 is provided with a silica gel layer 25, and the silica gel layer 25 extends along the circumferential direction of the inflatable pad 24.

[0062] Therefore, the silica gel layer 25 can further improve the fit of the inflatable pad 24 with the teeth and oral tissues of the patient due to its soft and smooth characteristics, thereby reducing friction and discomfort, and providing a more comfortable wearing experience for the patient.

[0063] Preferably, in an embodiment of the utility model, the rear side of the fixator 20 is provided with an extension 26, which extends circumferentially along the through hole 22.

[0064] In this way, the extension 26 extends circumferentially along the through hole 22, which can more effectively utilize the space in the back of the oral cavity and provide more support and protection for the tracheal tube 10 and the inflation tube 11. This helps to reduce patient discomfort or complications caused by improper or movement of the tube.

[0065] Preferably, in an embodiment of the utility model, the fixing piece 29 includes two adhesive pieces, and the two adhesive pieces are respectively arranged on both sides of the through hole 22 and are adapted to be attached to both sides of the tracheal tube 10.

[0066] In this way, the two adhesive pieces are respectively attached to both sides of the tracheal tube 10, forming a double fixing mechanism, which significantly enhances the stability of the tracheal tube 10 in the fixator 20. This design helps to prevent the tube from shifting due to patient activity or swallowing action, ensuring the accuracy and safety of intubation.

[0067] Preferably, in an embodiment of the utility model, the decompression protective sleeve 12 is made of silica gel material.

[0068] In this way, the silica gel material, with its soft, smooth, and skin-friendly properties, can significantly reduce the friction and pressure of the decompression protective sleeve 12 on the patient's oral mucosa, thereby improving the patient's comfort and reducing the discomfort caused by long-term intubation. The silica gel material has certain air permeability, allowing a moderate amount of air to pass through, which helps to reduce the moisture and discomfort of the oral mucosa, while also helping to maintain the cleanliness and dryness of the oral cavity, reducing the risk of infection.

[0069] Preferably, in an embodiment of the utility model, the lower end of the extension 26 is provided with a notch 27, and the notch 27 and the groove 23 are arranged opposite to each other, for passing the inflation tube 11.

[0070] In this way, the design of the notch 27 and the groove 23 reduces the friction and pressure of the inflation tube 11 on the patient's oral mucosa, thereby improving the patient's comfort. This design helps to reduce the discomfort caused by intubation and improve the patient's treatment experience and satisfaction.

[0071] Preferably, in an embodiment of the utility model, the middle part of the fixator 20 is provided with an operation port 28, and the operation port 28 penetrates the fixator 20.

[0072] Therefore, by arranging the operation port 28, the doctor can conveniently perform the operation or nursing operation, and the operation is separated from the tracheal tube 10, so that the tracheal tube 10 is not frequently touched or squeezed during the operation, and damage to the lips or oral mucosa of the patient caused by the tracheal tube 10 is avoided.
