DETAILED DESCRIPTION
[0027] The preferred embodiments of the present application will be described in detail below with reference to the drawings, which form a part of this application. The drawings together with the present application are used to explain the principles of the present application and are not intended to limit the scope of the present application.
[0028] EMBODIMENT
[0029] The tracheal tube fixing device provided in the embodiment is used for a bronchofibroscope, and can be used for fixing a tracheal tube of the bronchofibroscope. Figure 1 and Figure 2As shown, the tracheal tube fixing device comprises a fixing part 1 and a locking part 2; the fixing part 1 comprises a first sleeve 11, an air bag 12, a second sleeve 13 and an inflation part 14. The first sleeve 11 is sleeved in the second sleeve 13, and one end of the first sleeve 11 is fixedly connected with one end of the second sleeve 13; the air bag 12 is fixed on the inner wall of the first sleeve 11; after the inflation part 14 inflates the air bag 12, the air bag 12 can extrude the fiber bronchoscope wire inside the first sleeve 11, so that the position of the tracheal tube fixing device on the fiber bronchoscope wire is limited; the inner wall of the second sleeve 13 matches the outer diameter of the tracheal tube connector, and the locking part 2 is located outside the second sleeve 13 and can lock and fix the second sleeve 13 and the tracheal tube connector.
[0030] The tracheal tube fixing device of the embodiment can flexibly limit the position of the fixing device on the fiber bronchoscope wire, and is not easy to slide or rotate outside the fiber bronchoscope wire, by setting the first sleeve 11 and the air bag 12; and the connector of the tracheal tube can be fixed on the tracheal tube fixing device by setting the second sleeve 13 and the locking part 2, so that the tracheal tube is indirectly limited on the outer periphery of the fiber bronchoscope wire, which effectively prevents the tracheal tube from sliding or rotating along the fiber bronchoscope wire, thereby avoiding the sharp end of the tracheal tube from causing damage to the pharynx, vocal cords or other parts of the patient, and improving the safety of the operation.
[0031] As shown in Figure 2 and Figure 3 , the first sleeve 11 is a bendable medical catheter, and the first sleeve 11 can be made of a silica gel tube or a plastic tube; the second sleeve 13 is made of hard medical plastic and has a bottle cap shape with a through hole in the center, and one end of the first sleeve 11 is fixed at the position of the central through hole of the second sleeve 13.
[0032] As shown in Figure 2 , the air bag 12 is made of an elastic film material and is a closed annular part, and the outer ring wall of the air bag 12 is fixedly attached to the inner wall of the first sleeve 11, so that when the air bag 12 is not inflated, the tracheal tube fixing device can be smoothly sleeved outside the fiber bronchoscope wire.
[0033] Further, the upper end of the air bag 12 is communicated with the inflating component 14, which is used to inflate the air bag 12. Exemplarily, the inflating component 14 is a manual inflating ball, which includes a conduit 141, an inflating ball 142 and an exhaust valve 143. The two ends of the conduit 141 are communicated with the inflating ball 142 and the air bag 12 respectively. The air bag 12 can be inflated by squeezing the inflating ball 142. After the air bag 12 is inflated, the inner annular wall of the air bag 12 can extrude the outer periphery of the bronchofibroscope wire, so as to hang the tracheal tube fixing device on the outer wall of the bronchofibroscope wire. The air in the air bag 12 can be exhausted by opening the exhaust valve 143, so as to separate the tracheal tube fixing device from the bronchofibroscope wire. Since the air bag 12 is limited by the elastic extrusion between the bronchofibroscope wire, the tracheal tube can not slide or rotate, and the bronchofibroscope wire can also move slightly relative to the tracheal tube fixing device to adjust the depth of the tracheal tube under the condition of the inflation of the air bag 12.
[0034] As shown in Figure 3 , the second sleeve 13 is integrally formed by hard medical plastic, which includes a clamping part 131, a connecting plate 132 and an oxygen interface 133.
[0035] As shown in Figure 2 , the connecting plate 132 is used to be fixedly connected with the first sleeve 11. Exemplarily, the connecting plate 132 is an annular plate, and the inner annular edge is fixedly connected with one end of the first sleeve 11.
[0036] As shown in Figure 2 and Figure 3 , the clamping part 131 is a circular tube, and the inner diameter is smaller than the tracheal tube connector. Optionally, the length of the clamping part 131 is between 15mm-25mm, and the inner diameter is 2mm-3mm smaller than the outer diameter of the tracheal tube connector of different models. One end of the clamping part 131 is fixedly connected with the outer ring of the connecting plate 132, and the other end can be sleeved on the outer periphery of the tracheal tube connector, which is used to clamp the tracheal tube connector. Exemplarily, the clamping part 131 includes clamping plates 1311 and grooves 1312. The grooves 1312 are uniformly distributed on the cylindrical wall of the clamping part 131, so that the clamping plates 1311 arranged at intervals form a plurality of arc-shaped clamping plates 1311. When the tracheal tube connector is inserted, the clamping plates 1311 can be elastically deformed. The end of the clamping plate 1311 is provided with a chamfer 13111, and the edge diameter of the chamfer 13111 matches the outer diameter of the tracheal tube connector, so as to guide the tracheal tube connector to be smoothly inserted into the second sleeve 13. Preferably, the chamfer 13111 is an inclined chamfer.
[0037] The clamping part 131 of the embodiment can generate elastic clamping force on the oxygen interface due to elastic deformation of the clamping plate 1311 when the tracheal tube connector is inserted into the clamping part 131, and the tracheal tube is inserted into the fixing device, so as to indirectly limit the position between the tracheal tube and the bronchofibroscope wire, prevent the tracheal tube from sliding and rotating, and avoid damage to the pharynx and airway of the patient.
[0038] The oxygen interface 133 is arranged on the side wall of the second sleeve 13 between the connecting plate 132 and the groove 1312. The oxygen interface 133 is arranged along the radial direction of the second sleeve 13, has a gas passage in the center, and has a tapered step at one end of the oxygen interface 133 protruding from the outer wall of the second sleeve 13 to facilitate plugging connection with the oxygen tube. The other end is open between the first sleeve 11 and the second sleeve 13 and protrudes from the inner wall of the second sleeve 13. When the clamping part 131 is inserted into the clamping part 131, the oxygen interface 133 can limit the tracheal tube connector and simultaneously connect the oxygen interface 133 with the tracheal tube, so as to realize the oxygen supply function of the tracheal tube to the airway of the patient. It should be noted that the tracheal tube connector needs to cover the groove 1312 to prevent oxygen from flowing out of the gap of the groove 1312 during oxygen supply.
[0039] Further, as shown in Figure 1 The locking member 2 can lock the clamping part 131 and the tracheal tube connector to further fix the clamping of the clamping part 131 on the tracheal tube and prevent the tracheal tube from accidentally falling off the fixing device during operation.
[0040] Illustratively, the locking member 2 is a nut made of hard medical plastic, and the outer periphery of the clamping part 131 is provided with an outer thread 1313 matched with the locking member 2. During use, the locking member 2 is placed close to the oxygen interface 133, and after the tracheal tube connector is inserted into the clamping part 131, the locking member 2 is rotated to lock the clamping plate 1311 on the outer periphery of the tracheal tube connector. In order to facilitate locking operation, the outer periphery of the locking member 2 is also uniformly provided with a plurality of protrusions 21.
[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
