Description

Technical Field

[0001] The utility model belongs to the technical field of medical reflux drainage equipment, in particular to a tracheotomy tube reflux drainage device. Background Art

[0002] An endotracheal tube reflux drainage device is a medical device designed to collect and drain secretions or reflux from the oral cavity and airways of intubated patients to maintain airway patency and prevent complications. These devices typically include one or more components, such as an extraction tube, a contact head, an inlet port, and a retainer. These devices are tightly connected to the endotracheal tube and feature specialized structures to effectively extract secretions while minimizing damage to the patient's oral cavity and airway tissues.

[0003] Tracheotomy is a medical procedure that involves making a small incision in the front of the patient's neck to directly access the trachea. A tube, usually made of plastic or metal, is then inserted through the incision and into the trachea, creating an artificial airway. This procedure is mainly used to ensure the patency of the patient's airway and help those who cannot maintain effective breathing on their own due to various reasons (such as laryngeal obstruction, laryngeal edema, respiratory diseases, severe head trauma resulting in airway management difficulties, etc.).

[0004] In the prior art, after a patient's tracheotomy, there is a lack of a tracheotomy tube reflux drainage device that combines the tracheotomy tube and the reflux drainage device. The patient can only use the tracheotomy tube or the tracheotomy tube reflux drainage device separately. If the patient's airway secretions and gastric contents accumulate around or inside the tracheal tube and are not promptly drained, the risk of bacterial growth will increase, which may lead to respiratory system infection. Therefore, we hope to design a tracheotomy tube reflux drainage device with a new structure to solve this problem. Utility Model Content

[0039] As the first embodiment of the present invention, in actual use, after the patient's tube is cut, the cannula assembly 100 is inserted into the patient's tube cutting position in the manner and steps of a conventional tracheotomy cannula, and then the cannula assembly 100 is fixed to the patient's neck position using the strap tied to the fixing seat 130, and then the gas is introduced into the balloon 120 through the inflation tube 140 and the air hole 112 (the upper end of the inflation tube 140 is provided with a self-sealing inflation nozzle, which automatically seals after inflation is completed, and the gas in the balloon 120 will not leak out). After the balloon 120 is inflated, the outer tube 110 is fixed inside the patient's tube cutting, and then the outer tube 110 is fixed to the inner part of the patient's tube cutting. When oxygen needs to be delivered, open the sealing cap 152 and connect it to the oxygen supply equipment connector to supply oxygen (the pipeline connecting the oxygen supply equipment and the connector 151 at the upper end of the tracheal cannula 150 is equipped with an airflow control valve, which is a prior art).

[0044] In actual use, if there is no need to drain the reflux, the sealing cap 152 is used to seal the connector 211 at the upper end of the semicircular tube to prevent the entire device from leaking. When reflux drainage is required, the user plugs and fixes the lower end of the hose 220 with the connector 211 at the upper end of the semicircular tube 212, and then connects the other end to the plug-in connection at the lower end of the extractor 230. Since the drainage tube 210 has been installed when the cannula assembly 100 is installed, the user only needs to pull the extractor 230 to drain the reflux (the structure and working principle of the extractor 230 are the same as the structure and working principle of a medical syringe without a needle), and the reflux will pass through the outer tube The multiple obliquely arranged drainage holes 114 on the outer tube 110 near the upper side of the balloon enter the collecting chamber 113 (the obliquely arranged drainage holes 114 are arranged as follows: the endotracheal tube 150 is taken as the lower side of the outer tube 110, and the collecting chamber 113 is taken as the upper side of the outer tube 110. The outer tube 110 is respectively provided with an upwardly inclined drainage hole 114 on its lower left and lower right sides, and the outer tube 110 is also provided with corresponding drainage holes 114 on the upper side. The reflux material on the upper side of the balloon 120 is sucked from three directions to ensure the suction effect and avoid the situation where some directions cannot be sucked), and then enter the interior of the drainage tube 210, and finally enter the interior of the extractor 230 through the hose 220;

[0045] The drainage assembly 200, in conjunction with the cannula assembly 100, can meet the use requirements of both traditional tracheotomy cannulas and traditional reflux drainage devices, and only requires one installation, which not only reduces the labor intensity of medical staff but also reduces the discomfort of patients. It can perform reflux drainage as soon as it is needed, effectively preventing the accumulation of patient airway secretions and gastric contents around or inside the tracheal tube.
