Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a peritoneal flushing drainage tube. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, abdominal cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing.

[0003] A peritoneal lavage drainage tube is disclosed in Chinese patent CN220237448U, which belongs to the field of medical device technology. The peritoneal lavage drainage tube comprises a drainage tube body, wherein a plurality of side wall drainage holes are evenly spaced on the front end of the drainage tube body, a plurality of end face drainage holes are evenly spaced on the front end face of the drainage tube body, an inner core suction tube is arranged inside the drainage tube body, a plurality of suction holes are evenly spaced on the front end of the inner core suction tube body, a rear end of the inner core suction tube passes through the side wall of the drainage tube body to the outside of the drainage tube body, a threaded cover is threadedly sleeved on the rear end of the drainage tube body, a second rubber ring is fixedly embedded in the inner wall of the threaded cover, and a fixing ring is fixedly connected to the middle part of the front end of the drainage tube body.

[0004] The drainage tube requires the fluid in the abdomen to flow out naturally, and the drainage efficiency is low, which makes the abdominal drainage not thorough enough. In addition, some flushable drainage tubes cannot be extended forward during flushing, resulting in incomplete and incomplete flushing. In the above document, the pressing ring is pushed to drive the injection connector and the flushing tube to move, and the flushing tube can extend from the drainage tube body. However, during drainage, the end face drainage holes on the drainage tube body are easily blocked because there is no component that can clear the end face drainage holes. There is also a lack of limit fixation between the flushing tube and the drainage tube body. Once the medical staff loosens the flushing tube, the flushing tube will move unnecessarily, so it is necessary to continue to press the flushing tube, which is more troublesome to use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the problems in the related technology, the utility model proposes a peritoneal flushing drainage tube to overcome the above technical problems existing in the existing related technology.

[0025] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0027] See also Figure 1-Figure 4 As shown, the utility model is a peritoneal lavage drainage tube, comprising a drainage tube 1, a lavage tube 2 is arranged inside the drainage tube 1, a liquid guide tube 3 is fixedly connected to the outer surface of the drainage tube 1, a plurality of first liquid inlet holes 4 are opened at the end of the drainage tube 1, and a dredging component 5, a control component 6 and a fixing component 7 are arranged on the outer surfaces of the drainage tube 1 and the lavage tube 2, the dredging component 5 is used to dredge the first liquid inlet hole 4, the control component 6 is used to compare the positions of the dredging component 5 and the first liquid inlet hole 4, and the fixing component 7 is used to fix the lavage tube 2.

[0028] The drainage tube 1 is inserted into the patient's body, and the drainage tube 3 on the drainage tube 1 is connected to the negative pressure device. The negative pressure device is started to generate suction between the drainage tube 3 and the drainage tube 1. The accumulated fluid in the patient's body enters the drainage tube 1 through the first liquid inlet hole 4, and flows out from the drainage tube 3 after passing through the drainage tube 1. If it is found that the drainage speed is reduced due to the blockage of the first liquid inlet hole 4, the flushing tube 2 is rotated to drive the dredging component 5, and the position of the control component 6 on the flushing tube 2 and the drainage tube 1 is observed. The dredging component 5 is aligned with the first liquid inlet hole 4 and the flushing tube 2 is moved back and forth for a short distance, so that the dredging component 5 can dredge the first liquid inlet hole 4. After pushing the flushing tube 2 to move in the drainage tube 1, the fixing component 7 is buckled on the flushing tube 2 to fix it, and then the flushing tube 2 is connected to the flushing device to flush the patient's abdominal cavity.

[0029] The utility model connects the flushing tube 2 with the unblocking component 5. When the unblocking component 5 is used to unblock the first liquid inlet hole 4, the positions of the unblocking component 5 and the first liquid inlet hole 4 correspond to the positions of the control component 6 on the flushing tube 2 and the drainage tube 1 respectively. By observing the positions of the control component 6 on the flushing tube 2 and the drainage tube 1, it is possible to know whether the current unblocking component 5 is aligned with the first liquid inlet hole 4, thereby achieving precise unblocking. Through the connection between the fixing component 7 and the flushing tube 2, when the flushing tube 2 is pushed to move in the drainage tube 1 and the position of the flushing tube 2 is adjusted, the fixing component 7 is buckled on the flushing tube 2 to fix the flushing tube 2 and the drainage tube 1, thereby avoiding unnecessary movement of the flushing tube 2. At the same time, there is no need for medical staff to continuously press the flushing tube 2, which is more convenient to use.

[0030] In one embodiment, for the above-mentioned unclogging component 5, the unclogging component 5 includes a limit plate 501, the limit plate 501 is fixedly connected to the outer surface of the flushing pipe 2, the outer surface of the limit plate 501 is provided with a second liquid inlet hole 502, the outer surface of the limit plate 501 is fixedly connected with a unclogging rod 503, and the end of the drainage pipe 1 is fixedly connected with a limit tube 504.

[0031] The flushing tube 2 drives the limit plate 501 to rotate, and the limit plate 501 drives the unblocking rod 503 to rotate and align it with the first liquid inlet hole 4. The flushing tube 2 is pulled to move a simple short distance, so that the flushing tube 2 drives the unblocking rod 3 and the first liquid inlet hole 4 to make reciprocating motion to unblock it. Through the connection between the drainage tube 1 and the limit tube 504, the limit plate 501 will be restricted by the limit tube 504 when it moves, preventing the limit plate 501 from fitting with the drainage tube 1, leaving a gap between the limit plate 501 and the drainage tube 1. At the same time, the second liquid inlet hole 502 opened on the limit plate 501 can allow the accumulated liquid to pass through, avoiding the problem of reduced drainage speed during unblocking.

[0032] In one embodiment, for the above-mentioned control component 6, the control component 6 includes a first circular plate 601 and a second circular plate 604, the first circular plate 601 is fixedly connected to the outer surface of the flushing tube 2, the outer surface of the first circular plate 601 is fixedly connected with a first boss 602, the outer surface of the first boss 602 is provided with a first mark 603, the first boss 602 and the first mark 603 are on the same horizontal line as the dredging rod 503, the second circular plate 604 is fixedly connected to the end of the drainage tube 1, the outer surface of the second circular plate 604 is fixedly connected with a plurality of second bosses 605, the outer surfaces of the plurality of second bosses 605 are all provided with second marks 606, and the plurality of second bosses 605 and second marks 606 are respectively aligned one by one with the positions of the plurality of first liquid inlet holes 4.

[0033] When the flushing tube 2 is rotated, the flushing tube 2 drives the unblocking rod 503 and the first circular plate 601 to rotate simultaneously. The positions of the first boss 602 and the first mark 603 on the first circular plate 601 are always aligned with the unblocking rod 503. When the first mark 603 is aligned with the second mark 606, since the second mark 606 and the second boss 605 are aligned with the first liquid inlet hole 4, it means that the unblocking rod 503 is aligned with the first liquid inlet hole 4 at this time. Through the setting of the first mark 603 and the second mark 606, the positions of the unblocking rod 503 and the first liquid inlet hole 4 are more intuitive, which is convenient for medical staff to perform unblocking operations on the first liquid inlet hole 4.

[0034] In one embodiment, for the above-mentioned fixing component 7, the fixing component 7 includes a positioning belt 701, the positioning belt 701 is fixedly connected to the outer surface of the second circular plate 604, the outer surface of the positioning belt 701 is provided with a positioning hole 702, a positioning column 703 is inserted into the inside of the positioning hole 702, the positioning column 703 and the positioning hole 702 have the same diameter, the positioning column 703 is fixedly connected to the outer surface of the first circular plate 601, and a ball 704 is fixedly connected to the end of the positioning column 703, and the diameter of the ball 704 is slightly larger than the diameter of the positioning column 703.

[0035] The flushing tube 2 is pushed to move so that the positioning column 703 on its surface is aligned with the positioning hole 702 on the positioning belt 701. At this time, the positioning belt 701 is pushed to move downward so that the positioning hole 702 on the positioning belt 701 passes over the ball 704 and is plugged into the positioning column 703. The flushing tube 2 will be blocked by the positioning belt 701 when moving, thereby achieving the limit fixation between the flushing tube 2 and the drainage tube 1 and avoiding unnecessary movement of the flushing tube 2.

[0036] In one embodiment, for the above-mentioned flushing pipe 2 , a handle 8 is fixedly connected to the outer surface of the flushing pipe 2 , and an anti-slip protrusion 9 is fixedly connected to the outer surface of the handle 8 .

[0037] The rotating handle 8 drives the flushing tube 2 to rotate synchronously. During the rotation process, the anti-skid protrusions 9 on the handle 8 can increase the friction between the handle 8 and the hands of the medical staff to avoid slipping.

[0038] In one embodiment, for the above-mentioned flushing tube 2 , a plurality of liquid outlet holes 10 are opened on the outer surface of the flushing tube 2 , and the plurality of liquid outlet holes 10 are arranged in a circular array on the outer surface of the flushing tube 2 .

[0039] The flushing pipe 2 is connected to the flushing device. The liquid in the flushing device flows in the flushing pipe 2 and is sprayed out from the liquid outlet holes 10. The liquid outlet holes 10 in a circular array can increase the flushing area, which is beneficial to improving the flushing efficiency.

[0040] Through the above technical scheme, 1. Through the connection between the flushing tube 2 and the dredging component 5, when the dredging component 5 is used to dredge the first liquid inlet hole 4, the positions of the dredging component 5 and the first liquid inlet hole 4 correspond to the positions of the reference component 6 on the flushing tube 2 and the drainage tube 1 respectively. By observing the positions of the reference component 6 on the flushing tube 2 and the drainage tube 1, it can be known whether the current dredging component 5 is aligned with the first liquid inlet hole 4, thereby achieving precise dredging. Through the connection between the fixing component 7 and the flushing tube 2, when the flushing tube 2 is pushed to move in the drainage tube 1 and the position of the flushing tube 2 is adjusted, the fixing component 7 is buckled on the flushing tube 2. The flushing tube 2 is fixed to the drainage tube 1 to avoid unnecessary movement of the flushing tube 2. At the same time, there is no need for medical staff to continuously hold down the flushing tube 2, which is more convenient to use; 2. Through the connection between the flushing tube 2, the dredging rod 503 and the first mark 603, the dredging rod 503 is always aligned with the position of the first mark 603. When the first mark 603 is aligned with the second mark 606, since the second mark 606 is aligned with the first liquid inlet hole 4, it means that the dredging rod 503 is aligned with the first liquid inlet hole 4, which makes the position of the dredging rod 503 and the first liquid inlet hole 4 more intuitive, which is convenient for medical staff to perform dredging operations.
