Description

A new type of peritoneal lavage and drainage device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel abdominal cavity flushing and drainage device.

Background technique

After major abdominal surgery or surgery for severe infection, long-term, continuous, and unobstructed flushing and drainage of the surgical area can effectively keep the surgical area clean and promote postoperative recovery.

However, there are several problems with the currently used abdominal drainage tubes:

1) The tip of the tube is blocked. The tip of the drainage tube is usually open, and large pieces of normal tissue (such as the omentum) are easily embedded in the tube, causing blockage and difficulty in removing the tube;

2) Poor flushing effect. For some drainage tubes with flushing function, the water outlet is set in the drainage tube cavity. The water mainly flows back out of the body instead of entering the abdominal cavity, so the flushing efficiency is low or even ineffective.

3) The outlet of the pipe is blocked. Some drainage tubes with flushing function have a protrusion into the cavity at the tail end, which causes tissue debris to accumulate at the tail end and become blocked;

4) Drainage tube fall-off and surrounding inflammation: When the drainage tube is left in the body for a long time, the fixing sutures are prone to breakage, causing the drainage tube to fall off. In addition, the skin around the tube will become inflamed and ulcerated, causing persistent pain for the patient.

A Chinese utility model patent (CN213760139U) discloses a peritoneal lavage drainage tube, comprising a main body (0), one end of the main body (0) is sealed and the other end is open, a partition (1) is provided in the radial direction at the inner front part of the sealed end of the main body (0), the partition (1) divides the main body (0) into a liquid inlet cavity (2) and a drainage cavity (3), and the liquid inlet cavity (2) and the drainage cavity (3) are not connected;

A backward-inclined needle inlet tube (4) is provided at the rear of the liquid inlet chamber (2), a liquid outlet hole (5) is provided at the front of the liquid inlet chamber (2), and a liquid outlet (6) is provided at the front of the drainage chamber (3);

A retaining ring (8) is provided on the outer wall of the main body (0), and the retaining ring (8) is located in front of the needle inlet tube (4).

Although the existing patents have solved the problems of lumen head impaction and drainage tube detachment, there is still a problem of poor flushing in the prior art.

Example 1

As shown in Figure 1:

A novel abdominal cavity flushing and drainage device comprises a tube body 1 which is formed by a drainage tube 11 and a flushing tube 12 fixedly sleeved together. The head of the tube body 1 is closed and the tail is open. The tube body 1 is made of silicone. The drainage tube 11 is an inner tube and the flushing tube 12 is an outer tube. The tail end of the drainage tube 11 is fixedly connected to the tail end of the flushing tube 12, and the head end of the flushing tube 12 is made of polyethylene material.

A portion of the inner wall of the drainage tube 11 and a portion of the outer wall of the flushing tube 12 are fixedly connected, and a flushing channel 13 is formed by a gap between another portion of the inner wall of the drainage tube 11 and another portion of the outer wall of the flushing tube 12 that is not fixedly connected. A flushing hole 3 connected to the flushing channel 13 is opened at the head of the flushing tube 12. The flushing holes 3 are distributed in a shower shape at the head of the flushing tube 12, with one flushing hole 3 in the middle and multiple flushing holes 3 evenly distributed in a ring shape around it.

A flushing connector 6 connected to the flushing channel 13 is provided at a position 5 cm near the tail of the flushing tube 12. The flushing connector 6 is 4 cm long and is inclined at 45 degrees. The front end of the flushing connector 6 is made of polypropylene, and the tail end of the flushing connector 6 is made of polyethylene. The outer periphery of the end of the flushing connector 6 is provided with an external thread. When the flushing connector 6 is not used for flushing, a protective cover with an internal thread can be installed on the end of the flushing connector 6.

When the abdominal cavity needs to be flushed, a three-way tube or an infusion set can be firmly connected to the external thread to deliver physiological saline into the flushing channel 13 , and the physiological saline flushes from the flushing hole 3 in a shower-like manner.

The outer wall of the flushing tube 12 is provided with an annular balloon 2 made of silicone material, and the balloon 2 is connected to a polypropylene water inlet pipe 21 extending to the tail of the tube body 1. A medical one-way valve is installed at the end of the water inlet pipe 21. Physiological saline is injected through the medical one-way valve to expand the balloon 2 to form an anchor point in the body, thereby preventing the tube body 1 from falling out of the body. At the same time, the medical one-way valve can prevent the liquid from flowing out. When the tube body 1 needs to be removed from the body, the physiological saline in the ball valve can be extracted through a syringe connected to the medical one-way valve, and the ball valve retracts and no longer blocks the movement of the tube body 1.

A drainage hole 4 communicating with the interior of the drainage tube 11 is provided on the side wall of the flushing tube 12 on the side of the balloon 2 close to the head. The drainage holes 4 are arranged in a staggered manner on the side wall of the flushing tube 12 and are elliptical holes of 3 mm×5 mm.

The tail of the drainage tube 11 is made of polypropylene. The tail end of the drainage tube 11 is connected to a drainage bag via a drainage joint 7. The head of the tube body 1 is inserted into the abdominal cavity, and the tail of the tube body 1 is used for draining fluid in the abdominal cavity.

Two stacked dredging nets connected to the tail of the tube body 1 are provided near the head inside the drainage tube 11. The dredging nets include a ring and a nylon net. A fixed head is installed at the tail end of the tube body 1. The ring is connected to the fixed head through a traction line 54. One end of the traction line 54 extends from the inside of the drainage tube 11 to the outside of the tube body 1 and is fixed on the fixed head through the drainage joint 7.

The first dredging net 51 uses a red nylon rope as a traction line 54 , and the second dredging net 52 uses a green nylon rope as a traction line 54 . The first dredging net 51 is located at a position where the second dredging net 52 is close to the rear end of the pipe body 1 .

When the drainage tube 11 is not draining smoothly and the position near the drainage hole 4 in the tube body 1 is clogged, pull the red nylon rope to drive the first silt removal net 51, and then drive the clogged tissue to be removed through the drainage joint 7, and the drainage tube can be restored to be unobstructed; when the drainage hole 4 of the drainage tube 11 is clogged again, pull the green nylon rope to drive the second silt removal net 52, and the silt in the drainage tube 11 can be cleared again.

Example 2

As shown in Fig. 2, the difference between this embodiment and embodiment 1 is that the drainage tube 11 and the flushing tube 12 are coaxially arranged, and a flushing channel 13 is formed between the inner wall of the drainage tube 11 and the outer wall of the flushing tube 12. In addition, the other technical solutions are the same and will not be described again here.

The utility model has a compact structure and strong practicality, and can effectively replace the existing abdominal flushing drainage tube, avoid the problems of large pieces of normal tissue impaction at the head end of the tube cavity, backflow of flushing water, blockage inside the tube body and falling off of the drainage tube, improve the drainage and flushing efficiency, avoid abdominal effusion and infection, do not need to change the tube midway or unnecessary secondary laparotomy and debridement, and can remove the fixing line when necessary, reduce the patient's skin inflammation and pain, relieve the patient's wound pain, improve the patient's comfort and reduce the workload of medical staff.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
