Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a tracheal tube opening device. Background Technology

[0002] In clinical medicine, endotracheal tubes are essential tools for maintaining respiratory function, especially for patients with weak breathing, postoperative recovery, or those in intensive care. By inserting the tube through the mouth into the trachea and connecting it to a ventilator, continuous ventilation support can be provided. However, in practice, patients may bite down on the tube due to confusion, pain, or stress, causing the tube to deform or even collapse. This can severely obstruct airflow, affect ventilation effectiveness, and even threaten the patient's life.

[0003] Currently, common solutions to the problem of catheters being bitten open have certain limitations. One method is to directly replace the catheter, but this requires re-insertion, which is complex and may increase patient pain and risks, especially in emergency situations. Another method is to insert a thin rod with a conical tip to open the catheter, but to fully open the bitten area, this method requires the diameter of the rod to be close to the inner diameter of the catheter. This causes the peripheral wall of the rod to rub against the inner wall of the catheter during insertion, making insertion difficult. Moreover, the catheter may be completely blocked during the operation, causing the patient to be temporarily unable to breathe and posing a risk of suffocation. Therefore, existing technologies have the problem of being inconvenient to quickly open the bitten area of ​​the catheter. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a tracheal tube opening device, which solves the problem that it is inconvenient to quickly open the collapsed part of the tube in the prior art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A tracheal tube opening device, comprising a tube column with openings at both ends;

[0007] The outer diameter of the tubing is smaller than the inner diameter of the conduit. A connecting strip is provided at either end of the tubing. A sliding rod is fixed to the side of the connecting strip away from the tubing. The sliding rod is placed coaxially with the tubing.

[0008] A conical block placed coaxially is fixed to the end of the slide bar away from the connecting bar. The diameter of the conical block gradually decreases from the end near the slide bar to the end away from the slide bar.

[0009] A sliding disk is fitted on the slide rod, and a support mechanism is provided between the disk and the conical block. When the disk moves toward the conical block, the distance between the support mechanism and the central axis of the column gradually increases. The diameters of the conical block and the disk are both smaller than the outer diameter of the column.

[0010] When the disc approaches the conical block, the maximum distance between the supporting mechanism and the central axis of the column is greater than the diameter of the outer peripheral wall of the column; when the disc approaches the connecting bar, the maximum distance between the supporting mechanism and the central axis of the column is less than the diameter of the outer peripheral wall of the column.

[0011] A push rod is slidably connected inside the tubular column and placed on the same axis. The push rod is fixed to the end of the disk away from the conical block.

[0012] The principle and effect of the above technical solution are as follows:

[0013] When a patient accidentally bites down on the catheter, causing obstructed ventilation, the catheter should be immediately disconnected from the ventilator. The opening device of this application should then be inserted into the catheter, causing the cone block to continuously approach the bitten area. The cone block compresses the bitten area, initially opening it. Then, the push rod is manually pushed, causing the disc to approach the cone block, continuously expanding the opening mechanism. As the disc approaches the cone block, the distance between the opening mechanism and the central axis of the tubing gradually increases, further opening the bitten area. This allows for rapid opening of the bitten area. This application is applicable to effectively opening bitten areas of catheters with various inner diameters. Furthermore, since the diameters of the cone block and the disc are smaller than the outer diameter of the tubing, the opening process will not cause complete blockage of the catheter, reducing the possibility of patient suffocation during the opening process.

[0014] A camera is fixedly installed on the disk near the end of the cone block, with the camera facing horizontally outward from the outer side of the disk's peripheral wall.

[0015] The connecting strip is rotatably connected to the column. The push rod has a strip-shaped groove near the end of the disc. The strip-shaped groove and the push rod are placed on the same axis. The inner circumferential wall of the column near the end of the conical block has a circular groove. The two ends of the connecting strip pass through the strip-shaped groove and are rotatably engaged with the circular groove. The connecting strip and the slide rod are slidably connected in the strip-shaped groove.

[0016] The support mechanism includes a pair of linkages symmetrically placed about the slide bar. The two linkages are located in the same plane, and the central axis of the slide bar is located in the plane where the two linkages are located.

[0017] Each linkage group includes a pair of symmetrically placed hinged rods. The two hinged rods are arranged along the axis of the slide rod. Both ends of the hinged rods are rotatably hinged to mounting parts. A fixing part is provided between the two hinged rods. The mounting parts of the two hinged rods near the fixing block are fixed to the side of the fixing part near the slide rod. The mounting parts of the two hinged rods away from the fixing part are respectively fixed to the disc and the conical block. The hinged rods can rotate around the mounting part at either end in the plane where the two linkage groups are located.

[0018] All fixing parts are hemispherical, and the ends of the fixing parts away from the slide rod are spherical;

[0019] A handle is fixedly connected to the peripheral wall of the tubular column away from the end of the conical block;

[0020] The end of the tubular column away from the conical block is fixed with a fixing bar, and the push rod slides through the fixing bar away from the disc end, and the push rod is rotatably connected to the fixing bar;

[0021] A throttle is fixed to the end of the push rod away from the disc.

[0022] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0023] Fixed connection: refers to a connection method in which two or more components are tightly connected together by welding, gluing or other methods, and cannot be easily separated.

[0024] Sliding connection: This type of connection allows components to slide relative to each other in a specific direction and is typically used for connecting devices or components that require linear movement.

[0025] The beneficial effects of this utility model are:

[0026] 1. The conical block compresses the crumbled area, initially opening it up. Then, a push rod is manually pushed, causing a disc to move closer to the conical block, continuously expanding the expansion mechanism. As the disc moves closer to the conical block, the distance between the expansion mechanism and the central axis of the tubing gradually increases, further opening the crumbled area. This allows for rapid opening of the crumbled area and is applicable to effectively opening crumbled areas of catheters with various inner diameters. Since the diameters of the conical block and disc are smaller than the outer diameter of the tubing, the catheter will not be completely blocked during the opening process, reducing the possibility of patient suffocation.

[0027] 2. The camera setup allows for easy observation of the inside of the deflated area after it has been opened, and inspection of whether the steel wire layer inside the guide tube is broken.

[0028] By opening the strip-shaped through groove and the ring groove, the support mechanism opens up the crumbled part. Then, by rotating the push rod, the push rod can drive the connecting strip, the sliding rod, the conical block, the disc and the support mechanism to rotate, so as to fully open up the crumbled part. At the same time, the disc can drive the camera to rotate synchronously, so as to take a comprehensive picture and check the crumbled part.

[0029] 3. Through the coordinated arrangement of hinge rods, mounting parts, fixing parts and discs, the two hinge rods are controlled to fold or unfold by driving the disc to move closer to or away from the conical block, thereby adjusting the distance of the fixing part away from the central axis of the slide rod. The fixing part away from the slide rod is spherical, which reduces the scratches on the inner wall of the guide tube during the process of fully opening the crumbling part.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] This combination Figures 1 to 5This describes an embodiment of an endotracheal tube opening device; specifically, the endotracheal tube opening device is constructed as a split structure, comprising a tube body 100, a connecting strip 200, a sliding rod 300, a conical block 400, a disc 500, an expansion mechanism, and a push rod 600. The opening device is inserted into the endotracheal tube, causing the conical block 400 to continuously approach the crimped portion. The conical block 400 compresses the crimped portion, initially opening it. Then, the push rod 600 is manually pushed, causing the disc 500 to move closer to the conical block 400. This allows the expansion mechanism to continuously unfold, and as the disc 500 approaches the cone block 400, the distance between the expansion mechanism and the central axis of the tubing 100 gradually increases. The expansion mechanism further expands the collapsed portion, enabling rapid expansion of the collapsed portion. This application is applicable to effectively expanding collapsed portions of catheters with various inner diameters. Furthermore, since the diameters of the cone block 400 and the disc 500 are smaller than the outer diameter of the tubing 100, the catheter will not be completely blocked during the expansion process, reducing the possibility of patient suffocation during the expansion process.

[0038] Please refer to Figures 1 to 5 A tracheal tube opening device, comprising a tube 100 with openings at both ends;

[0039] The outer diameter of the tubing 100 is smaller than the inner diameter of the conduit. A connecting strip 200 is provided at either end of the tubing 100. A sliding rod 300 is fixed on the side of the connecting strip 200 away from the tubing 100. The sliding rod 300 is placed coaxially with the tubing 100.

[0040] A conical block 400, placed coaxially, is fixed to the end of the slide rod 300 away from the connecting bar 200. The diameter of the conical block 400 gradually decreases from the end near the slide rod 300 to the end away from the slide rod 300.

[0041] A sliding disk 500 is fitted on the slide rod 300. A support mechanism is provided between the disk 500 and the cone block 400. When the disk 500 moves toward the cone block 400, the distance between the support mechanism and the central axis of the column 100 gradually increases. The diameters of the cone block 400 and the disk 500 are both smaller than the outer diameter of the column 100.

[0042] When the disc 500 approaches the conical block 400, the maximum distance between the support mechanism and the central axis of the column 100 is greater than the diameter of the outer peripheral wall of the column 100; when the disc 500 approaches the connecting bar 200, the maximum distance between the support mechanism and the central axis of the column 100 is less than the diameter of the outer peripheral wall of the column 100.

[0043] A push rod 600 is slidably connected inside the tube column 100 and placed coaxially. The push rod 600 is fixed to the end of the disc 500 away from the conical block 400.

[0044] When a patient accidentally bites down on the catheter, causing obstructed ventilation, the catheter should be immediately disconnected from the ventilator. The opening device of this application should then be inserted into the catheter, causing the cone block 400 to continuously approach the bitten area. The cone block 400 compresses the bitten area, initially opening it up. Then, the push rod 600 is manually pushed, causing the disc 500 to move closer to the cone block 400, continuously expanding the opening mechanism. As the disc 500 moves closer to the cone block 400, the distance between the opening mechanism and the central axis of the tubing 100 gradually increases, further opening the bitten area. This application is applicable to effectively opening bitten areas of catheters with various inner diameters. Since the diameters of the cone block 400 and the disc 500 are smaller than the outer diameter of the tubing 100, the opening process will not cause complete blockage of the catheter, reducing the possibility of patient suffocation during the opening process.

[0045] Preferably, the common size of the catheter is 5.0 mm to 8.0 mm, and the outer wall diameter of the tubing 100 in this application is 4.0 mm to 4.5 mm, so as to facilitate the insertion of the tubing 100 into the catheter;

[0046] Preferably, the length of the tubing 100 ranges from 100 to 200 mm.

[0047] A camera 700 is fixedly installed on the end of the disc 500 near the conical block 400, with the camera 700 facing horizontally towards the outer side of the peripheral wall of the disc 500. Preferably, the camera 700 of this device can be used in conjunction with devices such as a display screen in the prior art to observe the inner side of the crumbled part after it has been opened, and to check whether the steel wire layer inside the guide tube is broken.

[0048] The connecting strip 200 is rotatably connected to the column 100. The push rod 600 has a strip-shaped through groove 601 near the end of the disc 500. The strip-shaped through groove 601 and the push rod 600 are placed on the same axis. The inner circumferential wall of the column 100 near the end of the conical block 400 has an annular groove 101. The two ends of the connecting strip 200 pass through the strip-shaped through groove 601 and are rotatably engaged with the annular groove 101. The connecting strip 200 and the slide rod 300 are slidably connected in the strip-shaped through groove 601. After the crumbling part is opened by the spreading mechanism, the push rod 600 is rotated. The push rod 600 can drive the connecting strip 200, the slide rod 300, the conical block 400, the disc 500 and the spreading mechanism to rotate, so as to fully open the crumbling part. At the same time, the disc 500 can drive the camera 700 to rotate synchronously during rotation, so as to take a comprehensive picture inspection of the crumbling part.

[0049] The support mechanism includes a pair of linkages symmetrically placed about the slide bar 300. The two linkages are located in the same plane, and the central axis of the slide bar 300 is located in the plane where the two linkages are located.

[0050] Each linkage assembly includes a pair of symmetrically placed hinge rods 801. The two hinge rods 801 are arranged along the axis of the slide rod 300. Both ends of the hinge rods 801 are rotatably hinged to mounting parts 802. A fixing part 803 is provided between the two hinge rods 801. The mounting parts 802 of the two hinge rods 801 near the fixing block are fixed to the side of the fixing part 803 near the slide rod 300. The mounting parts 802 of the two hinge rods 801 away from the fixing part 803 are respectively fixed to the disc 500 and the conical block 400. The hinge rods 801 can rotate around the mounting part 802 at either end in the plane where the two linkage assemblies are located.

[0051] By driving the disc 500 to move closer to or further away from the conical block 400, the two hinge rods 801 are controlled to fold or unfold, thereby adjusting the distance of the fixed part 803 from the central axis of the slide rod 300.

[0052] Each mounting component 802 includes a pair of symmetrically placed fixing blocks, with a rotating shaft fixed between the two fixing blocks. The ends of the hinge rods 801 are rotatably sleeved on the rotating shafts. The mounting component 802 is fixedly connected to the conical block 400, the disc 500, or the fixing part 803 through the fixing blocks.

[0053] All fixing parts 803 are hemispherical, and the ends of fixing parts 803 away from the slide bar 300 are spherical; this reduces scratches on the inner wall of the conduit when it is opened.

[0054] A handle 900 is fixedly connected to the peripheral wall of the end of the tubing 100 away from the conical block 400; by manually holding the handle 900, the device can be easily pushed into the conduit, and the stability of the tubing 100 can be improved when the push rod 600 is manually pushed to move.

[0055] A fixing strip 102 is fixed to the end of the tube column 100 away from the conical block 400. The end of the push rod 600 away from the disk 500 slides through the fixing strip 102, and the push rod 600 is rotatably connected to the fixing strip 102. The fixing strip 102 improves the guiding performance of the push rod 600 during the pushing and pulling process and the stability during the rotation process.

[0056] A handle 602 is fixed to the end of the push rod 600 away from the disc 500; the handle 602 is designed to facilitate manual pushing, pulling and rotating of the push rod 600.
