Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a chest tumor water drainage device. Background Art

[0002] The fluid in the pleural cavity is absorbed from the venous end of the capillaries, and the rest of the fluid is recycled into the blood by the lymphatic system. Filtration and absorption are in a dynamic balance. If this dynamic balance is destroyed by a tumorous lesion in the chest, causing the fluid in the pleural cavity to form too quickly or be absorbed too slowly, and pleural effusion occurs clinically, it is necessary to drain the effusion through a drainage device.

[0003] The drainage tube needs to be connected to subsequent closed drainage bottles, negative pressure suction devices, etc. Currently, the drainage tube is mainly bent to adapt to subsequent equipment. The effect of absorbing accumulated water will be affected after the drainage tube is bent. A chest tumor water drainage device is now proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a chest tumor water drainage device to solve the above problems.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a chest tumor water drainage device includes a liquid inlet pipe, a movable pipe is slidably connected to the inside of the liquid inlet pipe, a drainage pipe is fixedly installed inside the liquid inlet pipe, and the movable pipe is slidably connected to the surface of the drainage pipe.

[0006] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0007] Further technical solution: a fixed block is fixedly installed on the top of the movable tube, a threaded rod is rotatably connected inside the fixed block, an outer fixed ring is fixedly installed on the top of the liquid inlet tube, a handle is fixedly installed on one end of the threaded rod, and the other end of the threaded rod is rotatably connected to the surface of the outer fixed ring.

[0008] Further technical solution: the drainage tube surface is fixedly mounted with a mounting block, the mounting block surface is hinged with a bracket, the fixed block surface is provided with symmetrical through grooves, and the bracket is slidably connected inside the through grooves.

[0009] Further technical solution: A pull rod is slidably connected inside the fixed block, a slider is fixedly connected to the end of the pull rod, a symmetrical plug rod is fixedly installed on the surface of the slider, a plug hole is opened on the surface of the bracket, and the plug rod is movably inserted in the plug hole.

[0010] Further technical solution: a sliding groove is provided inside the fixed block, the sliding block is slidably connected inside the sliding groove, a spring is fixedly installed on the surface of the sliding block, and the other end of the spring is fixedly connected inside the sliding groove.

[0014] Beneficial Effects

[0015] The utility model provides a chest tumor water drainage device, which has the following beneficial effects compared with the prior art:

[0016] 1. To avoid bending of the drainage tube, the threaded rod is rotated by the handle so that the moving tube inside the liquid inlet tube can rise inside the liquid inlet tube and rise to the top plate. The limiting ring at the bottom of the moving tube fits with the top plate to prevent the moving tube from slipping out. The length of the entire device is adjusted so that the drainage tube has enough length to connect closed drainage bottles, negative pressure aspirators and other machines, thereby improving the drainage tube's effect in absorbing accumulated water.

[0017] 2. When the movable tube is rising, the fixed block stretches the bracket. When the movable tube moves to the highest point inside the liquid inlet tube, the bracket is stretched to the maximum extent and is flush with the top of the liquid inlet tube. At the same time, one end of the bracket is attached to the patient's skin surface to support the entire device. When the effusion is extracted, the movable tube is recovered to the inside of the liquid inlet tube, so that the bracket can slide back into the through groove for storage. The insertion rod is inserted into the socket at the end of the bracket to limit the bracket. After the bracket is recovered, the length of the liquid inlet tube is consistent with the length of the movable tube plus the liquid inlet tube, so that the drainage tube can be avoided from being bent again after the effusion is extracted, thereby extending the service life of the drainage tube.

When the movable tube 2 is rising, the fixed block 21 opens the bracket 41. When the movable tube 2 moves When it moves to the highest point inside the liquid inlet tube 1, the bracket 41 is stretched to the maximum extent and is flush with the top of the liquid inlet tube 1. At the same time, one end of the bracket 41 is attached to the patient's skin surface to support the entire device. When the accumulated fluid is extracted, the moving tube 2 is recovered to the inside of the liquid inlet tube 1, so that the bracket 41 can slide back into the through groove 24 for storage, and the insertion rod 27 is inserted into the socket 42 at the end of the bracket 41 to limit the bracket 41. After the bracket 41 is recovered, the length of the liquid inlet tube 1 is consistent with the length of the moving tube 2 added to the liquid inlet tube 1, so that the drainage tube 3 can be avoided from being bent again after the accumulated fluid is extracted, thereby extending the service life of the drainage tube 3.
