Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal tube connector. Background Art

[0002] When treating anesthetized patients, in order to keep the patient's airway open, a tracheal tube is generally used to provide a channel for gas to flow between the patient's lungs and the anesthesia respiratory system. In order to more flexibly connect the tracheal tube to the respiratory system, a tracheal tube connector is usually used.

[0003] For example, Chinese patent CN219290417U discloses a three-way drug delivery connector that can be connected to a tracheal tube, including a device body, a connecting port, and a fixing port. The top of the device body is fixedly connected with the connecting port, the left end of the device body is fixedly connected with the fixing port, the right end of the device body is fixedly connected with the sleeve port, the top of the connecting port is nested and connected with a connecting tube, the top of the connecting tube is fixedly connected with a ventilator, the left end of the fixed port is embedded and connected with a fixing sleeve, the left end of the connecting port is nested and connected with a drug delivery catheter, the surface of the drug delivery catheter is fixedly connected with a buckle, the left end of the drug delivery catheter is fixedly connected with an atomization interface, the atomization interface can allow the drug to be input into the patient's body in a mist form, so that the patient can receive the drug faster, the connecting mechanism can ensure that the patient's oxygen is continuous while delivering the drug, thereby improving the functionality of the device body, and the drug delivery mechanism can enable the device to better administer the drug to the patient, thereby improving the patient's treatment efficiency.

[0004] However, the three-way drug delivery connector that can be connected to the endotracheal tube cannot be connected to the ventilator at the same time during endotracheal intubation, which will delay the rescue time in an emergency. The guide balloon connection tube on the endotracheal tube cannot be fixed, which can easily cause accidents.

[0005] Based on this, the utility model designs a tracheal tube connector to solve the above problems. Utility Model Content
