Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bifurcated flushable drainage tube. Background Technology

[0002] Drainage tubes are commonly used medical devices in surgical procedures, primarily used to drain fluid or gas from body cavities and prevent infection and complications. Common types of drainage tubes include chest drainage tubes and abdominal drainage tubes, which are widely used in abdominal surgery, thoracic surgery, and other surgeries requiring drainage.

[0003] Most existing drainage tubes are single-channel designs, which have the following drawbacks: (1) In some surgeries, such as laparoscopic primary suture of the common bile duct, it is necessary to drain the space in front of and behind the common bile duct at the same time. A single-channel drainage tube cannot meet the needs. The existing solution is to place two single-channel drainage tubes, which aggravates the patient's postoperative discomfort and increases the workload of clinical nursing.

[0004] (2) Single channels are prone to blockage in some cases, such as when there is a lot of fluid accumulation in the abdominal cavity, chest cavity, etc., and the secretions are viscous. Existing drainage tubes with flushing channels are all internal circulation, and the flushing water does not flow through the drainage area. Even if the drainage tube is flushed and cleared, there is still a risk of being blocked by viscous fluid accumulation and secretions. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide a bifurcated flushable drainage tube, including a connecting seat, a connecting mechanism disposed on the connecting seat, a fixed sheath mechanism disposed on the connecting seat, a movable sheath mechanism disposed on the fixed sheath mechanism, and a suction mechanism penetrating the connecting seat, the fixed sheath mechanism, and the movable sheath mechanism; the movable sheath mechanism includes a first movable component fixed at one end on the fixed sheath mechanism, a second movable component fixed at one end on the fixed sheath mechanism, and a movable negative pressure suction pipe fixed at one end on the fixed sheath mechanism.

[0007] Specifically, the connecting mechanism includes a first sliding groove fixedly disposed on the connecting seat, a threaded connecting pipe rotatably disposed on the first sliding groove, and a sealing ring fixedly disposed on the connecting seat.

[0008] Specifically, the fixed sheath mechanism includes a first fixed sheath fixedly mounted on the connecting seat, a first fixed pipe fixedly mounted on the first fixed pipe, a second fixed pipe fixedly mounted on the first fixed pipe, a third fixed pipe fixedly mounted on the first fixed pipe, a second fixed sheath fixedly mounted on the connecting seat, a fourth fixed pipe fixedly mounted on the second fixed pipe, a fifth fixed pipe fixedly mounted on the second fixed pipe, a sixth fixed pipe fixedly mounted on the second fixed pipe, and a fixed negative pressure suction pipe with one end fixedly mounted on the connecting seat.

[0009] Specifically, the first movable component includes a first movable sheath fixed at one end to a first fixed sheath, a first movable pipe fixed to the first movable sheath and connected to a first fixed pipe, a second movable pipe fixed to the first movable sheath and connected to a second fixed pipe, and a third movable pipe fixed to the first movable sheath and connected to a third fixed pipe.

[0010] Specifically, the second movable component includes a second movable sheath fixed at one end to a second fixed sheath, a fourth movable pipe fixed to the second movable sheath and connected to a fourth fixed pipe, a fifth movable pipe fixed to the second movable sheath and connected to a fifth fixed pipe, and a sixth movable pipe fixed to the second movable sheath and connected to a sixth fixed pipe.

[0011] Specifically, the suction mechanism includes a first flushing pipe that passes through the first fixed pipe and the first movable pipe and passes through the connecting seat, a second flushing pipe that passes through the fourth fixed pipe and the fourth movable pipe and passes through the connecting seat, a first drainage pipe that passes through the second fixed pipe and the second movable pipe and passes through the connecting seat, and a second drainage pipe that passes through the fifth fixed pipe and the fifth movable pipe and passes through the connecting seat.

[0012] Specifically, the third and sixth movable pipes are equipped with supports; and a filter membrane is provided at one end of the third and fourth movable pipes.

[0013] The beneficial effects of this utility model are: (1) The drainage tube described in this utility model can be used as an ordinary drainage tube, connecting only one side of the drainage tube and the flushing tube; when different parts need to be drained, the first movable sheath and the second movable sheath are torn apart and inserted into different parts that need drainage.

[0014] (2) An independent external flushing pipe is provided. In some areas, such as the abdominal cavity and pleural cavity, there is a lot of fluid accumulation and thick secretions. Single-channel drainage tubes are prone to blockage and cannot be flushed. Existing drainage tubes with flushing pipes are designed for internal circulation, that is, the flushing fluid will not flow through the area that needs to be drained. Even if the drainage tube is flushed and cleared, there is still a risk of blockage. This utility model provides an independent flushing pipe, so that the flushing fluid can flow through the drainage area, dilute the fluid accumulation and secretions in the area that needs to be drained, prevent blockage, and at the same time prevent the organs in the drainage area from being infected.

[0023] Reference Figures 1-7 As shown, the present invention discloses a bifurcated flushable drainage tube, comprising a connecting seat 1, a connecting mechanism 2 disposed on the connecting seat, a fixed sheath mechanism 3 disposed on the connecting seat, a movable sheath mechanism 4 disposed on the fixed sheath mechanism, and a suction mechanism 5 penetrating the connecting seat, the fixed sheath mechanism, and the movable sheath mechanism; the movable sheath mechanism includes a first movable component 41 fixed at one end to the fixed sheath mechanism, a second movable component 42 fixed at one end to the fixed sheath mechanism, and a movable negative pressure suction pipe 43 fixed at one end to the fixed sheath mechanism; the connecting mechanism is used to connect the flushing drainage tube to the negative pressure suction device; the fixed sheath mechanism is immovable; the suction mechanism is used for flushing and drainage; the first movable component and the second movable component are disposed on both sides of the negative pressure suction pipe, and the connecting surface is provided with an easy-tear groove. The first and second movable components can be separated, allowing simultaneous drainage of different areas. For example, in laparoscopic primary closure of the common bile duct, drainage can be simultaneously performed in the spaces anterior and posterior to the common bile duct. Both components also have flushing channels. In some areas, such as the abdominal and pleural cavities, where there is significant fluid accumulation and thick secretions, single-channel drainage tubes are prone to blockage and cannot be flushed. Existing drainage tubes with flushing channels have an internal circulation design, meaning the flushing fluid does not flow through the area requiring drainage. Even after flushing and clearing, there is still a risk of blockage. This invention features independent flushing channels, allowing the flushing fluid to flow through the drainage area, diluting the accumulated fluid and secretions, preventing blockage, and simultaneously preventing infection of the organs in the drainage area.
