It should be noted that, in the occluder 100a for trachea, after the elastic tube 110 is plugged into the air inlet sleeve and the first occluding tube 120 is mounted on the elastic tube 110, the occluding area can be adjusted after the second occluding tube 130 below the first occluding tube 120 is rotated; the principle of the adjustment here is that the first plugging plate 122 on the inner wall of the first plugging tube 120 and the second plugging plate 132 on the second plugging tube 130 are in contact with each other to prevent air leakage, and the area of the second plugging plate 132 covering the first plugging plate 122 can be adjusted in the rotation process of the second plugging tube 130, so that the ventilation area can be adjusted.
Specifically, as shown in fig. 1, the cuff of fig. 1 is attached to the neck after cutting the trachea, and has a cuff air inlet thereon, and the occluder 100a for trachea provided in the present invention is used to occlude the air inlet therein. In the actual treatment process, the plugging area needs to be adjusted to observe whether the patient can normally ventilate or not.
Specifically, the elastic tube 110 is made of elastic material, such as medical rubber, which is slightly deformed after being brought into the air inlet of the cannula to prevent the cannula from falling off. The first plugging tube 120 and the elastic tube 110 can be detachably connected in a threaded mode, and plugging plates on the two plugging tubes, namely, the first plugging plate 122 and the second plugging plate 132 are in a vertically-propped relationship, so that air leakage is prevented from occurring in a gap between the first plugging plate and the second plugging plate, and the regulation and control of the plugging area are influenced. In order to increase the tightness, a sealing element such as a sealing strip can be arranged at the edge of the first plugging plate 122 and the edge of the second plugging plate 132 to achieve a better sealing effect.

Preferably, the cross-sectional area of the second plugging plate 132 may be slightly larger than one-half of the cross-sectional area of the second plugging tube 130, which may increase the sealing effect between the first plugging plate 122 and the second plugging plate 132.
Specifically, the equal inner diameters of the elastic tube 110, the first occlusion tube 120, and the second occlusion tube 130 mean that the inner diameters are substantially equal, and for example, the remaining portion of the first occlusion tube 120 except for the portion extending into the elastic tube 110 may be substantially equal to the inner diameter of the elastic tube 110.
Specifically, for better adjustment, marks may be disposed on the outer walls of the first blocking tube 120 and the second blocking tube 130, so as to facilitate identification, for example, a mark area is disposed in a semi-cylindrical structural range of the first blocking plate 122 on the outer wall of the first blocking tube 120, and a mark area is also disposed in a semi-cylindrical structural range of the second blocking plate 132 on the outer wall of the second blocking tube 130, so that rotation adjustment is facilitated, and the first blocking tube 120 is ensured to be fixed in the adjustment process, so that the second blocking tube 130 is rotated.
Further, referring to fig. 3 to 5, a rotation groove 124 is formed on the inner wall of the first plugging tube 120, and a rotation flange 134 matched with the rotation groove 124 is formed on the top outer wall of the second plugging tube 130; a plurality of fastening strips 126 are arranged on the inner wall of the lower part of the rotating groove 124 of the first plugging tube 120 in a ring mode, one ends of the fastening strips 126 are fixedly connected with the inner wall of the first plugging tube 120, and the free ends of the fastening strips 126 extend to the inner cavity of the pipeline of the first plugging tube 120 and to the direction close to the rotating groove 124.
Specifically, the matching of the rotating grooves 124 and the rotating flanges 134 on the first plugging tube 120 and the second plugging tube 130 can be realized, and the rotating matching of the two can be conveniently carried out to adjust the plugging area. The fastening strips 126 are in contact with the wall of the second plugging tube 130, and can play a clamping role after being deformed, so that the second plugging tube 130 is prevented from moving in the use process to generate errors of plugging areas.
Further, referring to fig. 6, the fastening strip 126 includes a fixing section 1262, an elastic section 1264 and a clamping section 1266 extending in a vertical direction, one end of the fixing section 1262 is fixedly connected with the inner wall of the first plugging tube 120, the other end of the fixing section 1262 is fixedly connected with the bottom of the clamping section 1266, and the top of the clamping section 1266 is fixedly connected with the bottom of the elastic section 1264; the cylindrical space enclosed by the clamping segments 1266 of the plurality of fastening strips 126 is sized to accommodate the outer wall of the second occlusion tube 130, and the free ends of the elastic segments 1264 extend in a direction toward the center of the lumen of the first occlusion tube 120.
In particular, the plurality of fastening strips 126 may be of the same size and shape that encircle the inner wall of the first occlusion tube 120 so that the vertically extending gripping sections 1266 may cooperate with the cylindrical outer wall of the first occlusion tube 120 to act to grip the first occlusion tube 120. The elastic segment 1264 can generate a small amount of deformation, so as to increase the clamping effect.
In particular, the larger diameter of the fixed segment 1262 compared to the elastic segment 1264 and the clamping segment 1266 increases the robustness of the connection. The whole material of the fastening strip 126 may be rubber having a certain strength.
Further, referring to fig. 3 and 7, a filling port 112 is provided on the elastic tube 110, a filling pipe 114 is provided in the elastic tube 110, and one end of the filling pipe 114 passes through the filling port 112. In the treatment process, the liquid adding pipeline 114 can be communicated with infusion equipment such as an infusion apparatus and the like, so that the liquid medicine is added for airway humidification.

After the external pipeline is sleeved on the first connecting pipeline 1146, clamping can be performed through the arc-shaped second connecting pipeline 1148, and the external pipeline is not easy to fall off from the external pipeline because the pipe diameter of the second connecting pipeline 1148 close to one end of the first connecting pipeline 1146 is larger, so that the operation safety is strong.
Further, the end of the filling tube body far away from the connecting tube 1144 is located above the top wall of the elastic tube 110, so that the external liquid medicine can be introduced into the air passage for humidification, etc.
Specifically, the pipe diameter of the liquid adding pipe main body is smaller than that of the connecting pipeline 1144, so that stable conveying is facilitated in the infusion process, and the phenomena of splashing and the like caused in the process due to overlarge fluid sectional area of the liquid medicine are prevented.
