Description
Technical Field
[0001] The present invention relates to the technical field of endotracheal intubation, and in particular to a monitoring type anti-pressure sore endotracheal intubation. Background Art
[0002] Currently, endotracheal intubation is an emergency technique in which a special endotracheal tube (usually a disposable plastic tube with a cuff) is placed into the trachea through the mouth or nose and the glottis.
[0003] In medical practice, pressure sores, as a common complication, often trouble patients and medical workers, especially when it comes to invasive medical devices such as endotracheal tubes. Because they need to maintain the fixation and patency of the airway for a long time during use, they often inevitably produce strong and / or long-term pressure on the surrounding tissues. This pressure, sometimes combined with shear force, can easily cause localized damage to the skin and (or) subcutaneous soft tissues, namely, pressure sores. During the fixation process of the endotracheal tube, its fixator often needs to be close to the skin around the patient's mouth to ensure the stability of the endotracheal tube and prevent slippage. However, this close contact and long-term compression, especially at the bone protuberance or in areas with weak skin, will significantly increase the risk of pressure sores. Although the existing endotracheal tube design can meet the clinical treatment needs to a certain extent, it still has obvious deficiencies in reducing the occurrence of pressure sores. Therefore, how to improve the design of the endotracheal tube and its fixator to reduce the incidence of pressure sores in patients and improve the comfort and safety of treatment has become a technical problem that needs to be solved urgently in the current medical field.

[0019] Example 1 like Figure 1 to Figure 9 As shown, a monitoring type anti-pressure sore endotracheal intubation comprises an endotracheal intubation 1 and an intubation holder 2, wherein the endotracheal intubation 1 passes through the interior of the intubation holder 2, and is characterized in that the intubation holder 2 comprises a holder body 21, a sliding plate 212, a top cover 23 and a binding strap 241, wherein the holder body 21 is installed inside the intubation holder 2, a dressing plate 210 is fixedly connected to the bottom of the intubation holder 2, two symmetrically arranged long axes 211 are fixedly connected inside the holder body 21, a sliding plate 212 is movably sleeved on the outer circumferential surfaces of the two long axes 211, a fixed tube 22 is fixedly connected inside the sliding plate 212, a threaded connection block 221 is fixedly connected to the top of the fixed tube 22, and a threaded sleeve 221 is threaded on the top of the threaded connection block 221. A top cover 23 is provided, and both sides of the cannula holder 2 connected to the main body are fixedly connected with fixing blocks 24, and one side of the fixing block 24 is fixedly connected with a strap 241. Through the arrangement of the cannula holder 2, the sliding plate 212 and other structures, the cannula holder 2 adopts high-density dressings and elastic bandages to ensure a close fit and comfort with the patient's mouth. The sliding plate 212 design can be flexibly adjusted according to clinical needs. The clamping structure of the embedded block 213 and the elastic rubber 214 pad is stable and reliable. The top cover 23 is connected by threads, which can easily fix the cannula body 11 and provide a visual window, which is convenient for diagnosis and treatment, sputum suction, oral care, specimen collection and other operations, can effectively prevent ventilator-associated pneumonia, and improve patient safety and the convenience of clinical operations.
[0020] like Figure 1 to Figure 6 As shown, the threaded connection block 221 is fixedly connected to the limiting connection block 222 inside, and a pressing tongue 224 is movably sleeved on the outer circumference of the limiting connection block 222.

After the embedded block 213 is fixed, the position of the sliding plate 212 is fixed; The process of removing the endotracheal tube 1 is as follows: loosen the Velcro 242, rotate the top cover 23, and release the fixing effect of the tongue depressor 224 on the tube body 11, remove the tube holder 2, then connect the suction device to the sputum suction connector 181, suck out the sputum in the trachea, and finally suck out the gas in the cuff 12 through the indicator balloon 14, and then remove the endotracheal tube 1; Through the setting of the cannula holder, sliding plate and other structures, the cannula holder adopts high-density dressing and elastic bandage to ensure a close and comfortable fit with the patient's mouth and head skin. The sliding plate design can be flexibly adjusted according to clinical needs. The clamping structure between the embedded block and the elastic rubber pad is stable and reliable. The top cover is connected by threads, which can easily fix the cannula body and provide a visual window to facilitate diagnosis, suction, oral care, specimen collection and other operations. It can effectively prevent ventilator-associated pneumonia and improve patient safety and the convenience of clinical operations.
[0024] Example 2 like Figure 1 to Figure 9 As shown, the endotracheal cannula 1 includes a cannula body 11 and two cuffs 12. The cannula body 11 is slidably assembled inside the fixed tube 22. The two cuffs 12 are fixedly sleeved on the outer peripheral surface of the cannula body 11. One side of the two cuffs 12 is fixedly connected to an inflation connecting tube 13. One end of the two inflation connecting tubes 13 is commonly connected to an indicator balloon 14. Through the arrangement of the endotracheal cannula 1, the cuffs 12 and other structures, the endotracheal cannula 1 is equipped with a drug injection tube 16 and a charging connector 171, which is convenient for real-time monitoring (whether the endotracheal cannula body is in the main The unique design of the turntable 15 and the limit seal 151 can realize the alternating inflation and deflation of the two cuffs 12 at regular intervals according to clinical needs, reduce the long-term compression of the instrument on the local skin and subcutaneous soft tissue, and effectively prevent pressure damage in the airway. At the same time, the two air bags 12 are controlled through one entrance, which indirectly reduces the risk of tube slippage caused by too many tubes, providing patients with a safer and more comfortable intubation experience.
[0025] like Figure 1 to Figure 9 As shown, a turntable 15 is rotatably installed inside the indicating balloon 14, a limit seal 151 is fixedly connected to the top of the turntable 15, a pull button 152 is fixedly connected to the bottom of the turntable 15, and through grooves are provided inside the limit seal 151 and the turntable 15, which fit with one of the inflation connecting tubes 13.
[0026] like Figure 1 As shown, a charging connector 171 is installed inside the cannula body 11 , a connecting cable 17 is installed on one side of the charging connector 171 , and a camera 172 is installed on one end of the connecting cable 17 .
[0027] like Figure 1 As shown, a drug injection tube 16 is fixedly connected to one side of the cannula body 11, a sputum suction tube 18 is fixedly connected to the inside of the cannula body 11, one end of the sputum suction tube is fixedly connected to a sputum suction connector 181, and sputum suction holes 182 are provided on the tops of the two cuffs 12, and the sputum suction tube 18 is connected to the two sputum suction holes 182.
[0028] In this embodiment, based on the same concept as in Embodiment 1, this embodiment proposes: When the endotracheal tube 1 is in use, medicine can be injected through the injection tube 16, and an external video connection device can be connected through the charging connector 171. Through the connection between the video connection device and the charging connector 171, the image of the camera 172 can be monitored in real time (to confirm whether the tube body 11 is in the main airway, whether there is aspiration, tracheal wall compression, sputum volume in the trachea, etc.). After the tube body 11 is inserted into the patient's main airway, the pull button 152 is turned, and the sliding of the pull button 152 causes the turntable 15 to rotate. When the turntable 15 rotates, the limit seal 151 seals and protects it. During the rotation of the turntable 15, the through grooves on the turntable 15 and the limit seal 151 are aligned with one of the inflation connection tubes 13 The air in the airway wall is overlapped, and the corresponding cuff 12 is inflated by the syringe through the indicating balloon 14, so that the cuff 12 is fitted with the airway wall to fix the cannula body 11. After a period of fixation, the through groove is overlapped with another inflatable connecting tube 13 through the above steps, and the air inflated cuff 12 is inflated by the syringe. After the balloon is inflated, the previous balloon is deflated by rotating the knob 152 and the needle tube. This method of controlling the two cuffs 12 separately according to the interval time of clinical needs through one entrance can effectively prevent pressure damage in the airway and reduce the risk of pipeline slippage caused by too many pipelines. During the use of the cuff 12, the sputum in the upper respiratory tract gathers at the top of the cuff 12. Through real-time monitoring, when suction is needed, the suction device is connected to the suction connector 181, and the sputum is sucked out in time through the suction hole 182 and the suction tube 18.
[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
