[0001] The utility model relates to the technical field of medical instruments, in particular to a novel abdominal cavity drainage device. Background Art

[0002] A patent application with application number CN202410590664.1, titled "An Anti-seepage Medical Drainage System Capable of Monitoring Intra-abdominal Pressure," describes the following: It includes an anti-seepage system, monitoring equipment, a ventilation tube, and a sensor line. The anti-seepage system consists of an anti-seepage component, a support ring, a drainage tube, pressure sensor 1, and pressure sensor 2. The anti-seepage component has a hole inside for the drainage tube to pass through, and the inner wall of the hole only wraps around the drainage tube to ensure a seal between the drainage tube and the anti-seepage component. The anti-seepage component contains an airbag that swells when inflated, blocking the surgical incision from inside the abdominal cavity and preventing extravasation of abdominal contents. Pressure sensor 1 measures the pressure difference between the airbag in the anti-seepage component and the inside of the abdominal cavity, causing the airbag to inflate and seal the surgical incision. Pressure sensor 2 measures the pressure inside the abdominal cavity. The present invention provides an anti-seepage medical drainage system capable of monitoring intra-abdominal pressure. It has the characteristics of preventing leakage of abdominal contents, real-time monitoring of intra-abdominal pressure, and a compact and easy-to-carry size. It effectively improves patient comfort and ensures the life safety of patients after surgery.

[0003] The above patent uses an inflated air bag to block the incision in the patient's body to prevent the extravasation of abdominal contents. However, the inflated air bag will cause the incision to turn outward, which is not conducive to the healing of the incision. Improvements are needed. Utility Model Content

[0004] In view of the above problems, a new abdominal drainage device is now provided to solve the problems existing in the prior art.

[0005] The specific technical solutions are as follows:

[0006] A new type of abdominal drainage device includes a drainage tube and an inflatable filling component. The inflatable filling component is arranged on the outer periphery of the drainage tube. A protective ring is also provided on the outer periphery of the drainage tube. The protective ring is located above the inflatable filling component. When the drainage tube enters the patient's body and the inflatable filling component is inflated, the inflatable filling component squeezes the incision from the inside so that the outside of the incision fits against the lower side wall of the protective ring to prevent the incision from turning outward.

[0007] The above-mentioned new abdominal drainage device also has the following characteristics: the inflation filling component includes an annular airbag, which surrounds the outer circumference of the drainage tube; an inflation tube is provided on the inner wall of the drainage tube; the lower end of the inflation tube is connected to the annular airbag, and the upper end of the inflation tube extends to connect to an external inflation device; when the annular airbag is inflated, the annular airbag extends outward to form a blockage on the inside of the incision.

[0008] The beneficial effects of the above solution are as follows: the annular airbag is attached to the drainage tube when it is in an uninflated state, and when the annular airbag enters the body, it is expanded by inflation to achieve the effect of sealing the incision.

[0009] The above-mentioned new abdominal drainage device also has the following characteristics: the inflation filling component includes multiple closing pieces and multiple expansion drive parts, and the multiple closing pieces are evenly arranged around the outer periphery of the drainage tube, and the upper end of the closing piece is hinged to the outer side wall of the drainage tube, the lower part of the closing piece is provided with the expansion drive part, and the inner side wall of the drainage tube is provided with an inflation tube, the lower end of the inflation tube is connected with the expansion drive part, and the upper end of the inflation tube extends to connect with an external inflation device. When the expansion drive part is inflated, the expansion drive part drives the vertical closing piece to rotate until it rotates to a horizontal state.

[0010] The beneficial effect of the above solution is that the expansion drive part is inflated to push the sealing piece to rotate from a state of being in contact with the drainage tube to a state perpendicular to the drainage tube. When the sealing piece is perpendicular to the drainage tube, it can block the incision.

[0011] The above-mentioned new abdominal drainage device also has the following characteristics: the expansion drive part includes an expansion airbag, and the side wall of the drainage tube is provided with a plurality of accommodating grooves, and the expansion airbag is arranged in the accommodating grooves. When the expansion airbag is in an unexpanded state, the expansion airbag is completely in the accommodating grooves. At this time, the closing piece is in a state of being in contact with the side wall of the drainage tube. When the expansion airbag is inflated, the expansion airbag pushes the closing piece to rotate and expand to a state perpendicular to the drainage tube.

[0012] The beneficial effects of the above solution are as follows: the expansion airbag is arranged below the hinge point between the sealing piece and the drainage tube. According to the lever principle, the expansion airbag only needs to be expanded to a very small volume to drive the sealing piece.

[0013] The novel abdominal cavity drainage device mentioned above also has the following characteristics: a flexible connecting piece is provided between two adjacent closing pieces, and the closing pieces and the connecting piece together form an umbrella-shaped structure.

[0014] The beneficial effect of the above solution is that the gaps between the closing pieces are blocked by the connecting piece, thereby further strengthening the sealing of the incision.

[0015] In summary, the beneficial effects of this solution are:

[0016] The novel abdominal drainage device provided by this utility model prevents the incision from everting due to the inflatable filling component by installing an inflatable filling component inside the body to block the incision, and provides a protective ring outside the incision to fit the incision. This prevents the incision from everting due to the inflatable filling component, and facilitates incision healing. BRIEF DESCRIPTION OF THE DRAWINGS
