The utility model discloses a right double lumen bronchial cannula with a movable side hole, which relates to the technical field of medical instruments and comprises a main branch tube and an auxiliary branch tube, a first cuff is arranged at the lower end between the main branch tube and the auxiliary branch tube, a second cuff is arranged at the lower end of the auxiliary branch tube and positioned at the lower end of the first cuff, and a connecting channel is arranged in the auxiliary branch tube. The lower end of the connecting channel is provided with a side hole assembly, and the upper end of the connecting channel is provided with a moving mechanism. The side hole assembly comprises an elastic support, the elastic support is fixed in the lower end of the auxiliary supporting pipe, and a side hole is formed in the elastic support. According to the right double-lumen bronchial cannula with the movable side hole, through the overall structural matching design, when the position is improper, the catheter does not need to be adjusted, only the position of the side hole needs to be adjusted, and therefore the right lung superior lobe opening can be aligned more accurately, and the most suitable ventilation mode is customized for each patient.

The application discloses a controllable tip bronchial cannula, which comprises a tracheal catheter, a first inflatable cuff and a second inflatable cuff which are arranged on the outer wall of the tracheal catheter at intervals, wherein at least one ventilation hole is arranged on the tracheal catheter between the first inflatable cuff and the second inflatable cuff, the ventilation hole penetrates the tracheal catheter wall and communicates with the lumen of the tracheal catheter; an elastic film is arranged in the lumen of the tracheal catheter, the elastic film is provided with at least one third opening which communicates with the lumen of the tracheal catheter, and the third opening is arranged in a staggered mode with the ventilation hole; and a control component is further arranged, which is used for controlling the elastic film to switch between closing the ventilation hole and opening the ventilation hole. The bronchial cannula of the application makes the airway management of lung isolation more refined, breaks through the traditional left / right lung isolation, and realizes the precise physical isolation of the operation area and the non-operation area in units of lung lobes.

The invention relates to the technical field of thermoplastic elastomers, in particular to a disposable visible double-lumen bronchial cannula and a preparation method thereof. The preparation method comprises the following steps: mixing an ethylene-propylene thermoplastic elastomer, polypropylene resin, an antibacterial silver material and an antibacterial zinc oxide material, and carrying out melt extrusion, cooling and traction to obtain the pipe. And the pipe is sequentially subjected to water washing, alcohol washing, drying and plasma treatment, and the pretreated pipe is obtained. The preparation method comprises the following steps: adding raw materials such as hydroxyethyl acrylamide, acrylic acid, polyvinylpyrrolidone, allyl quaternary ammonium salt, allyl triphenyl phosphonium bromide and 1-allyl imidazole to obtain an antibacterial hydrogel solution; and soaking the pretreated pipe in the antibacterial hydrogel solution, taking out the pipe, and performing ultraviolet irradiation to obtain a finished product. The finished product prepared by the invention has excellent antibacterial property and lubricity, so that the finished product has a wide application prospect in the technical field of thermoplastic elastomers.

The application discloses an electrode-adjustable nerve monitoring double-lumen cannula, which at least comprises a left monitoring tube and a right monitoring tube arranged separately; the left monitoring tube and the right monitoring tube both comprise a double-lumen cannula, a tracheal connector, a bronchial cannula and a terminal cannula; the double-lumen cannula is connected with the tracheal connector, and the tracheal connector is connected with the bronchial cannula; the bronchial cannula is connected with the terminal cannula; a tracheal air bag is arranged on the end of the double-lumen cannula close to the tracheal connector; a bronchial air bag is arranged on the bronchial cannula close to the terminal cannula; a flexible metal sheet is sleeved on the double-lumen cannula, and a regulating mechanism for regulating the position of the flexible metal sheet is further arranged on the double-lumen cannula; the flexible metal sheet can move along the length direction of the double-lumen cannula under the action of the regulating mechanism; the flexible metal sheet is connected with an electrode wire; the metal sheet designed in the scheme is adjustable, that is, the up-and-down displacement of the metal sheet on the tracheal cannula main pipe can be realized.

The application is a coating device and method applied to a visual double-lumen bronchial cannula, belonging to the technical field of coating on visual double-lumen bronchial cannula, comprising a plasma cleaning mechanism and a vacuum coating mechanism, the plasma cleaning mechanism comprises a vacuum treatment box, the inside of the vacuum treatment box is placed with a visual double-lumen bronchial cannula, the inner bottom wall of the vacuum treatment box is rotationally connected with a support, and the top of the support supports the visual double-lumen bronchial cannula. The application solves the problems that the coating is easy to fall off, the overall thickness is uneven, and local sputum adhesion occurs when the coating material is directly sprayed on the surface of the product. In the application, the surface of the visual double-lumen bronchial cannula is treated by the plasma cleaning mechanism, and a hydrophilic group is generated on the surface of the visual double-lumen bronchial cannula, thereby improving the hydrophilicity of the surface of the visual double-lumen bronchial cannula. There are hydrophilic and hydrophobic parts in the coating material.
