Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to the technical field of oxygen inhalation connectors. Background Art
[0002] Tracheotomy is a common surgery to cut the cervical trachea and insert a silicone tracheal tube to relieve dyspnea caused by laryngeal dyspnea, respiratory dysfunction or lower respiratory tract secretion retention. After the patient's condition stabilizes, medical staff consider removing the tracheotomy tube as soon as possible, and replace it with a metal tube for trial blocking training before extubation. Some patients need to use high-flow oxygen to assist ventilation due to changes in their condition, and the metal tracheotomy tube cannot be directly connected to the high-flow oxygen inhalation pipeline. At present, there is no special connector for connection in clinical practice. The models of metal tracheal tubes are mainly No. 8, No. 9, and No. 10. The connection tube of a fixed size cannot be used for different models of tracheotomy tubes. In clinical practice, we tried to use the breathing circuit connectors at the front end of different models of tracheal tubes to connect, but after the connector was removed, the remaining tracheal tube part was in a scrapped state. At the same time, this method is not easy to fix and is prone to falling off. In addition, tracheotomy patients are prone to airway bleeding due to various reasons. When nebulization hemostasis is ineffective, a micropump is used to inject hemostatic drugs. Currently, the micropump extension tube used in clinical practice is directly placed into the tracheotomy cannula, and then fixed to the cannula with tape. However, this method is very easy for the patient to cough it out, which can easily cause contamination and increase the risk of lung infection. Utility Model Content
[0003] The purpose of the utility model is to solve the problems in the prior art and to propose a high-flow oxygen inhalation connector suitable for different types of metal tracheostomy tubes, which can solve the above problems. The connector is individually packaged, strictly meets the sterility requirements, reduces clinical workload, and has a high promotion significance.
[0004] To achieve the above-mentioned purpose, the utility model proposes a high-flow oxygen inhalation connector suitable for different types of metal tracheotomy tubes, including a syringe, an injection valve, a high-flow oxygen inhaler interface, a humidification connection port, an inner core and an air bag, wherein the inner core is a hollow cylinder, the outer wall of the inner core is wrapped with an air bag, the air bag is connected to the injection valve, the injection valve is connected to the syringe, the inner core is connected to the high-flow oxygen inhaler interface, the high-flow oxygen inhaler interface is communicated with the inner core, the high-flow oxygen inhaler interface is connected to the high-flow oxygen inhaler, and the high-flow oxygen inhaler interface is connected to the humidification connection port.
[0005] Preferably, the gas injection valve is a one-way gas injection valve.
[0006] Preferably, the air inlet end of the gas injection valve matches the nipple of the syringe, and when the nipple of the syringe presses against the gas injection valve, the valve is pushed inward to open, and when the syringe is removed, the valve automatically pops out and closes.
[0007] Preferably, a base is provided between the inner core and the interface of the high-flow oxygen absorber, and fixing belts are provided at both ends of the base, and the fixing belts are connected to the fixing belts of the tracheal tube.
[0008] Preferably, the airbag is connected to the air injection valve through an air intake pipe.
[0009] The beneficial effects of the utility model: the utility model eliminates the need to try different types of connectors when using different types of metal tracheostomy tubes for high-flow oxygen inhalation therapy. The size of the built-in connector is controlled by injecting gas, which can match different types of tracheostomy tubes and meet the needs of different types of tubes, which is very convenient; the humidification connection port can avoid airway dryness, formation of sputum crust in the airway or contamination of the humidification liquid, reduce lung infection and reduce clinical work time and workload.
