Description

Technical Field

[0001] The utility model relates to the technical field of chest drainage tube flow cut-off, in particular to a chest drainage tube flow cut-off device. Background Art

[0002] Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water seal bottle lower than the position, so as to discharge gas or collect liquid in the chest cavity, so that the lung tissue reopens and restores function. It is widely used as a treatment method for drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases. The defect of the chest drainage tube interruption device in the prior art is that when the patient who uses chest drainage in the prior art needs to be examined or the drainage bottle is replaced, the medical staff need to fold the drainage tube used by the patient to interrupt the flow of the liquid therein, and the folded drainage tube is generally clamped with an ordinary clip, and then the medical staff performs further nursing and replacement work. In this process, the clip clamped on the folded drainage tube is easy to fall off due to loose clamping, resulting in the outflow of liquid in the drainage tube, or the outside air enters the patient's chest cavity from the drainage tube, endangering the patient's life safety.

[0003] After searching, the patent with announcement number CN213432475U discloses a chest drainage tube interruption device, including a base, which is a square body and is provided with at least one through groove running through the front and back, and a U-shaped groove perpendicular to the through groove is opened near the top wall of the base, and the U-shaped groove is used for the drainage tube to pass through; an extrusion component, which is movably arranged in the base, and can squeeze downward the drainage tube across the through groove. The utility model has a simple structure and can automatically bend a harder chest drainage tube through a downward pressing action, so that it can completely interrupt the flow at at least two places, and the interruption effect is better. After pressing down, the extrusion component automatically engages, making the interruption more stable, avoiding infection of the patient's chest due to inhalation of air; on the other hand, the automatic bending of the harder drainage tube reduces the workload of medical staff, saves time and effort, and improves the work efficiency of medical staff to a certain extent.

[0004] The technical solution has the following problems:

[0005] Although the drainage tube can be inserted into the U-shaped groove, when the drainage tube is in normal drainage state and there is no need to squeeze the component to cut off the flow, there is no limit on the drainage tube. The drainage tube is easily affected by external factors (such as pulling and dragging), which can easily cause the drainage tube to fall out of the U-shaped groove and cause the base to fall off, which is inconvenient. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that although the drainage tube can be inserted into the U-shaped groove, when the drainage tube is in a normal drainage state and there is no need to squeeze the assembly to cut off the flow, the drainage tube is not limited, and the drainage tube is easily affected by external factors (such as pulling and dragging), which may easily cause the drainage tube to break away from the U-shaped groove and cause the base to fall off, which is quite inconvenient.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1

[0029] Reference Figure 1-5 A flow cut-off device comprises: a frame 1 and a drainage tube body 12. The frame 1 is provided with a U-shaped groove 2, which is designed to accommodate and fix the drainage tube body 12. The U-shaped groove 2 is also provided with a notch to facilitate the insertion and removal of the drainage tube body 12.

[0030] In order to realize the flow-breaking function of the drainage tube, a flow-breaking mechanism is also provided, which is mainly composed of a threaded rod 3, a movable plate 6 and two plug-in blocks 11. The threaded rod 3 is threadedly connected to the frame 1, and can be conveniently rotated and moved up and down along the thread of the frame 1. The two sides of the movable plate 6 are respectively slidably connected to the inner walls of the two sides of the frame 1, so that the movable plate 6 can stably slide up and down along the inner wall of the frame 1. The tops of the two plug-in blocks 11 are fixedly connected to the bottom of the movable plate 6, and the bottom ends thereof are designed to be arc-shaped, so that the plug-in blocks 11 can be inserted into the drainage tube body 12 when needed, thereby realizing the flow-breaking effect. The bottom end of the threaded rod 3 is rotatably connected to the top of the movable plate 6, so that when the threaded rod 3 rotates, the movable plate 6 can be driven to move up and down. For the convenience of operation, a groove 9 is also provided on the bottom inner wall of the frame 1 to accommodate the arc-shaped bottom of the plug-in block 11, so that the plug-in block 11 can move more smoothly. In addition, a handle 4 is fixedly provided on the top of the threaded rod 3 to facilitate personnel to rotate the threaded rod 3.

[0031] In order to prevent the drainage tube body 12 from escaping from the U-shaped groove 2, a limiting mechanism is also designed. The limiting mechanism includes two L-shaped plates 7 and two springs 14. Two cavities 13 are opened on the frame 1. The top of the spring 14 is fixedly connected to the top inner wall of the cavity 13, and the bottom end is fixedly connected to the top of the L-shaped plate 7. A through hole is opened at the bottom of the cavity 13. One side of the L-shaped plate 7 is slidably connected to the inner wall of one side of the cavity 13, and one end of the L-shaped plate 7 is located in the through hole. When the pull plate 8 is pulled upward, the movement of the pull plate 8 This drives the movement of the two L-shaped plates 7, so that the L-shaped plates 7 move in the cavity 13. At this time, the spring 14 is compressed, and the U-shaped groove 2 of the frame 1 is aligned with the drainage tube body 12. The drainage tube body 12 is placed in the U-shaped groove 2, and the hand pulling the pull plate 8 is released. At this time, the spring 14 is released, and the force of the spring 14 pushes the L-shaped plate 7 to move, so that the bottom end of the L-shaped plate 7 is inserted into the slot 15 of the U-shaped groove 2, thereby limiting the drainage tube body 12 to prevent it from escaping from the U-shaped groove 2.
