Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, and more specifically to an endotracheal cannula for airway stenosis. Background Art
[0002] Endotracheal intubation is a special endotracheal tube used for endotracheal intubation surgery. It is inserted into the patient's trachea through the mouth or nose. It is an important rescue technology for critically ill patients undergoing cardiopulmonary resuscitation, surgical anesthesia and respiratory dysfunction, and is also the most reliable means of maintaining a patency of the upper airway.
[0003] At present, when intubating a patient with airway stenosis, it is difficult for the endotracheal tube to pass through the narrow part. For example, the glottis is a narrow triangle, so only a thinner endotracheal tube can be used. However, a thinner endotracheal tube easily leads to higher ventilation resistance. In view of this, the inventor proposes an endotracheal tube for airway stenosis to solve the above-mentioned problems. Utility Model Content
[0004] The utility model aims to provide an endotracheal cannula for airway stenosis, which makes it easier for the endotracheal tube to pass through the stenosis and can solve the problem of increased ventilation resistance caused by the thinning of the front end tube.
[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a tracheal intubation tube for airway stenosis, comprising a catheter, an air outlet and a cuff, wherein an air outlet is provided at one end of the catheter, the diameter of the catheter portion from the end of the catheter close to the air outlet to the cuff changes from thin to thick, and a plurality of ventilation holes are provided at the catheter portion from the end of the catheter close to the air outlet to the cuff.
[0006] By adopting the above technical solution, the front end of the catheter is designed to change from thin to thick so that the catheter can pass through narrow places such as the glottis more easily. The catheter part from the end of the catheter close to the air outlet to the cuff is provided with multiple ventilation holes, which can effectively solve the problem of increased ventilation resistance caused by the thinning of the front end catheter opening.
[0007] The utility model is further configured as follows: it also comprises a vent pipe, one end of the vent pipe close to the air outlet is provided with a cuff, and the other end of the vent pipe is provided with a cuff inflation port.
[0008] By adopting the above technical solution, after the cuff is inflated, the airbag will be stuck in the respiratory trachea. On the one hand, it can prevent airway leakage, and on the other hand, it can fix the trachea to prevent it from falling off, and at the same time, it can effectively reduce some unnecessary complications of patients.
[0009] The utility model is further configured as follows: an air inlet piece is arranged at one end of the conduit away from the air outlet.
[0010] By adopting the above technical solution, an artificial channel is provided for clearing the respiratory tract, providing ventilation and oxygen supply, and suctioning the respiratory tract.
[0011] In summary, the utility model has the following beneficial effects:
[0012] 1. The diameter of the catheter part from the end of the catheter close to the air outlet to the cuff is designed to gradually increase from thin to thick, so that the catheter can pass through narrow places such as the glottis more easily during intubation.
[0013] 2. The catheter portion from the end of the catheter close to the air outlet to the cuff is provided with a plurality of ventilation holes, which can effectively solve the problem of increased ventilation resistance caused by the thinning of the catheter opening at the front end. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the structure of an endotracheal tube for airway stenosis in an embodiment of the utility model;
[0015] In the figure: 1. air outlet; 2. cuff; 3. vent; 4. catheter; 5. vent tube; 6. cuff inflation port; 7. air inlet. DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] Example:
[0018] A tracheal tube for airway stenosis, such as Figure 1 As shown, it includes a catheter 4, an air outlet 1 and a cuff 5. The air outlet 1 is provided at one end of the catheter 4. The diameter of the catheter 4 portion from the end of the catheter 4 close to the air outlet 1 to the cuff 5 changes from thin to thick, and the catheter portion from the end of the catheter 4 close to the air outlet 1 to the cuff 5 is provided with multiple ventilation holes 3, and the end of the catheter 4 away from the air outlet 1 is provided with an air inlet 7.
[0019] The device further comprises a vent pipe, one end of which close to the air outlet 1 is provided with a cuff 2 , and the other end of the vent pipe 5 is provided with a cuff inflation port 6 .
[0020] When using, position the patient, generally to lie flat with the head tilted back, so that the glottis is fully exposed. First, insert the catheter into the patient's glottis until it reaches the trachea, and then use the cuff inflation port to inflate the cuff so that the cuff is stuck in the respiratory trachea.
[0021] Working principle:
[0022] During intubation, the diameter of the catheter end near the air outlet becomes thinner, making it easier for the catheter to pass through narrow areas such as the glottis. The catheter part from the catheter end near the air outlet to the cuff is provided with multiple ventilation holes, which can effectively solve the problem of increased ventilation resistance caused by the thinning of the catheter at the front end.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
