Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, in particular to a soft sleeve for replacing a tracheal intubation catheter. Background Art
[0002] Oral endotracheal intubation is an important technical means to treat critically ill patients. In the intensive care unit, the endotracheal intubation tube often needs to be replaced due to factors such as sputum scab blockage, airbag rupture, and tube bite.
[0003] In the prior art, there are two common methods for replacing endotracheal tubes clinically:
[0004] The first method requires the old endotracheal tube to be pulled out of the oropharynx first, and then the new endotracheal tube is reinserted along the original path using laryngoscope, fiberoptic bronchoscope, light stick, ultrasound and other auxiliary methods. After the old endotracheal tube is pulled out, the swollen throat airway loses the support of the original tube, and the original artificial airway path is even difficult to find, which greatly increases the difficulty of reintubation.
[0005] The second method is to replace the catheter with the help of a replacement guide. The replacement guide is inserted into the old tracheal tube until the tip of the tube, and then the old tracheal tube is pulled out and a new tracheal tube is inserted along the replacement guide. The method of replacing the catheter with the help of a replacement guide is not suitable for situations where the old tube is narrow.
[0006] In conjunction with the above application, the current technical means for replacing oral endotracheal tubes have defects such as difficulty in reintubation, delayed reintubation, and inapplicability in some situations, which may cause hypoxia or iatrogenic damage in some patients during the tube replacement process.
[0007] In summary, we provide a soft sleeve for replacing endotracheal intubation tube. Summary of the invention
[0008] The object of the present invention is to provide a soft sleeve for replacing an endotracheal tube to solve the problems raised in the above background technology.
[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a soft cannula for replacing an endotracheal intubation catheter, comprising a soft cannula body, a longitudinal groove, a raised buckle, and an endotracheal intubation catheter, wherein the longitudinal groove is opened on the soft cannula body, the raised buckle is arranged on the soft cannula body, and the outer wall of the endotracheal intubation catheter is covered with the soft cannula body.
[0010] The present invention is further configured as follows: the soft sleeve body is C-shaped and is made of a flexible material.
[0011] The present invention is further configured as follows: a plurality of longitudinal grooves are provided on one side of the soft sleeve body, a plurality of raised buckles are provided on the other side of the soft sleeve body, and the longitudinal grooves are matched with the raised buckles.
[0012] The present invention is further configured as follows: It is characterized in that: the soft sleeve body forms an O-shaped tube body through the cooperation of the longitudinal grooves and the raised buckles, and the outer wall of the soft sleeve body is marked with length scales.
[0013] The present invention is further configured as follows: the inner diameter of the O-tube is slightly larger than the endotracheal intubation catheter, and the length of the soft sleeve body is 2 cm shorter than that of the endotracheal intubation catheter.
[0014] The present invention is further configured as follows: the outer wall of the endotracheal intubation tube is marked with a length scale, and the material of the endotracheal intubation tube is a flexible material.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The invention can make the soft cannula body deform by cooperating with each other through the longitudinal grooves and the raised buckles arranged on the soft cannula body, so that the tube replacement work is safer and more convenient. Before inserting the catheter, the soft cannula is first used to replace the old tracheal tube, so that the airway is always open during the whole process of tube replacement, reducing the difficulty and delay of reintubation, avoiding hypoxia caused by reintubation, and increasing the safety of tube replacement.
[0017] The soft sleeve provided in the present invention enables the user to replace the tube without inserting the guide into the old catheter during the tube replacement process, thereby avoiding iatrogenic damage caused by sputum crust in the old catheter falling into the airway.

By using the O-shaped tube body formed by the soft cannula body to replace the tube, the operation is simple, the difficulty of replacing the tube is reduced, and the labor cost is reduced.
[0030] like Figure 2 As shown, the soft sleeve body 1 is C-shaped and is made of flexible material.
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, one side of the soft cannula body 1 is provided with a plurality of longitudinal grooves 2, and the other side of the soft cannula body 1 is provided with a plurality of raised buckles 3, the longitudinal grooves 2 are matched with the raised buckles 3, and the soft cannula body 1 forms an O-type tube body 5 through the cooperation of the longitudinal grooves 2 and the raised buckles 3, and the outer wall of the soft cannula body 1 is marked with a length scale. The O-type tube body 5 replaces the endotracheal intubation catheter 4 during the tube replacement process, so that the airway remains open during the whole tube replacement process. It reduces the occurrence of difficulties in reintubation and delayed reintubation, avoids hypoxia caused by reintubation, and increases the safety of tube replacement.
[0032] like Figure 1 As shown, the inner diameter of the O-type tube body 5 is slightly larger than the endotracheal tube catheter 4, the length of the soft tube body 1 is 2 cm shorter than the endotracheal tube catheter 4, the outer wall of the endotracheal tube catheter 4 is marked with a length scale, and the material of the endotracheal tube catheter 4 is a flexible material.
