This invention provides an antibacterial and anti-adhesion double-balloon tracheostomy cannula and its preparation method. The invention involves constructing a coating material co-loaded with a newly developed tetradecyl antibacterial agent and chondroitin sulfate on both the cannula's surface and inner wall. This coating possesses both excellent hydrophilicity and strong antibacterial properties. The hydrophilicity makes it difficult for secretions to adhere; the antibacterial properties kill bacteria through contact, minimizing the development of drug resistance; and the anti-adhesion properties reduce the basis for biofilm formation. These three properties work synergistically to achieve full-chain protection from the "source" to the "process," significantly reducing the risk of luminal obstruction and VAP (ventilator-associated pneumonia), while also reducing the frequency of suctioning and mucosal damage, thus improving patient comfort.

The tray type support for preventing the Y-shaped end threaded pipe of the breathing pipeline from bending comprises a support body, the support body is provided with a far end and a near end, the far end of the support body is used for being detachably connected with a breathing machine, the near end of the support body is fixedly connected with a bearing piece through a connecting rod, the bearing piece comprises a long-strip-shaped bearing piece body and a set of hook-shaped pieces, and the long-strip-shaped bearing piece body and the hook-shaped pieces are fixedly connected with the support body. The long-strip-shaped supporting piece is provided with a long straight containing cavity used for containing a threaded pipe, the hook-shaped pieces are located on the two sides of the long-strip-shaped supporting piece respectively, and the three connecting rods between the frame body and the hook-shaped pieces and between the frame body and the long-strip-shaped supporting piece form a claw shape. The long-strip-shaped tray is matched with the hook-shaped pieces on the two sides to achieve stable supporting of the threaded pipe and accessory pipelines of the threaded pipe, aspiration caused by accumulated water in the threaded pipe can be effectively prevented, ventilator-related pneumonia is prevented, the structural design is reasonable, and use is convenient.

The utility model relates to medical instrument field discloses breathing machine water tank water injection control device, including humidification jar, the humidification jar includes jar body and jar cover, and the side wall of jar body upper portion is provided with water injection hole, and the jar cover is equipped with air inlet and vent, and the air inlet is connected with the air inlet pipe that extends into the jar body, and the vent is connected with the exhaust pipe, and the inboard rotation of jar cover is connected with L type lever, and the long arm end of L type lever is connected with the float ball, and the short arm end of L type lever is connected with elastic telescopic mechanism, and one baffle is rotationally connected on elastic telescopic mechanism, and the baffle is attached to the inner wall of jar body, and the baffle is closed or opened to water injection hole under the vertical sliding of L type lever drive. The utility model can solve the problem that the breathing machine water tank of prior art lacks liquid level control and causes the liquid reflux of breathing machine related pneumonia.

The utility model discloses an inflatable breathing pipeline supporting and fixing device which comprises a supporting air bag and a breathing pipeline fixing air bag, the supporting air bag is used for supporting a trachea cannula at the patient end, and the breathing pipeline fixing air bag is used for supporting and fixing a 360-degree spiral connector or a breathing pipeline. A connecting piece capable of stretching, retracting and swinging is arranged between the supporting air bag and the breathing pipeline fixing air bag, and the supporting air bag and the breathing pipeline fixing air bag are connected through the connecting piece. A breathing pipeline fixing structure used for placing and fixing a breathing pipeline is arranged at the top of the breathing pipeline fixing air bag. The trachea cannula has the advantages that the trachea cannula is convenient to use, and the occurrence rate of pressure sores and ventilator-related pneumonia caused by the trachea cannula can be effectively reduced.

The utility model discloses an inflation-free trachea cannula which comprises a trachea cannula body and a connector. An inflation-free sleeve bag is arranged at the patient end of the trachea cannula body, a pull rope is connected with the inflation-free sleeve bag after passing through the trachea cannula body so as to be used for controlling contraction of the inflation-free sleeve bag and further achieve expansion of the inflation-free sleeve bag to seal an airway of a patient, and the inflation-free sleeve bag is of a circular truncated cone structure. The utility model can be suitable for patients with different human anatomy structures, and can reduce the operation procedure of inflating the cuff by medical personnel in an operation; the situation that treatment is delayed due to tracheal intubation caused by cuff breakage is reduced; airway mucosa necrosis and postoperative scar stenosis of a patient caused by excessive inflation can be reduced; breathing machine related pneumonia caused by the fact that secretions enter the body of the patient due to too little inflation or wrinkles of the inflation-free cuff can be reduced; the phenomenon that the trachea cannula falls off due to movement of a patient during an operation can be reduced; when secretions or gastric reflux substances enter the airway of the patient, the secretions can be received more easily.

The utility model discloses a condensate water collecting device of a breathing machine, and belongs to the technical field of medical instruments. The device comprises a water accumulating cup and a water collecting bag, the water accumulating cup comprises a cup body and a liquid passing and air isolating assembly, a liquid outlet pipe is arranged at the bottom of the cup body, a valve A is installed on the liquid outlet pipe, one end of the liquid passing and air isolating assembly is connected with one end of the liquid outlet pipe and located in the cup body, and the water collecting bag comprises a bag body and a liquid inlet pipe arranged at the top of the bag body. One end of the liquid inlet pipe is connected with the end, away from the cup body, of the liquid outlet pipe. The liquid passing and gas isolating assembly located in the cup body and installed at one end of the liquid outlet pipe can isolate gas and only allow condensate water to circulate, so that gas in the water collecting bag is prevented from flowing back to the water accumulating cup and even a breathing machine pipeline, and the occurrence rate of breathing machine related pneumonia is further reduced.
