[0002] Intraperitoneal hyperthermic chemotherapy refers to the precise constant temperature, circulation perfusion of the perfusion fluid containing chemotherapy drugs, filling the abdominal cavity and circulating perfusion for a certain period of time. Through the combined effects of chemotherapy, hyperthermia and mechanical flushing, it can clear the abdominal cavity free cancer cells, subclinical lesions and tiny cancer nodules smaller than three millimeters, thereby achieving the prevention and treatment of peritoneal implantation and metastasis of malignant tumors to the peritoneum, omentum and other abdominal cavities.

[0003] Most of the existing flushing and drainage devices are composed of multiple structures such as a pipeline mechanism, a liquid storage device, a heating mechanism and a control mechanism. The pipeline mechanism is pre-buried in the patient's abdominal cavity, and the control mechanism draws the liquid heated by the heating mechanism in the liquid storage device to circulate and perfuse the patient's abdominal cavity. During the operation, the patient's abdominal cavity often produces more blood clots and necrotic substances. Smaller blood clots and necrotic substances are easy to enter the liquid storage device through the pipeline mechanism during the circulation process. Most of the existing technologies use filter plates to intercept blood clots and necrotic substances, making it difficult for them to enter the liquid storage device and pollute it. However, the filter plate is easily clogged by impurities, affecting the passage of the liquid medicine. In order to reasonably improve this problem, the present application proposes a peritoneal hot perfusion flushing and drainage device. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 4 As shown, a peritoneal hot perfusion flushing and drainage device proposed in one embodiment of the present application includes:

[0027] A liquid storage tank 1 is used to store liquid medicine for peritoneal hot perfusion. A liquid outlet pipe 2 is installed on its peripheral side. The liquid outlet pipe 2 can be connected to a flushing pipe buried in the patient's abdominal cavity. The flushing pipe is a prior art. The number of the liquid outlet pipes 2 must be consistent with the number of flushing pipes. The liquid medicine is led out of the liquid storage tank 1 from the liquid outlet pipe 2. A solution pump 3 is installed on the top of the liquid storage tank 1, and the output end of the solution pump 3 is connected to the inside of the liquid storage tank 1. The solution pump 3 is used to pump external liquid medicine into the liquid storage tank 1;

[0028] The filter box 4 has a liquid inlet pipe 5 installed on its top, which can be connected to the drainage tube buried in the patient's abdominal cavity. The drainage tube is a prior art. The number of liquid inlet pipes 5 must be consistent with the number of drainage tubes, and the bottom of the liquid inlet pipe 5 is connected to the input end of the solution pump 3 through a connecting pipe 6. When the solution pump 3 is working, the liquid in the patient's abdominal cavity can be pumped into the liquid storage box 1. Two filter plates 7 connected to each other are symmetrically arranged in the filter box 4. There is an acute angle between the two, and the connection end is connected to the top of the filter box 4. The two filter plates 7 are close to each other, and the ends away from each other are both constructed with an interception part, which is away from the top of the filter box 4 and contacts the inner wall of the filter box 4. The two filter plates 7 cut off the inner diameter of the filter box 4. When the liquid medicine with blood clots and necrotic substances passes through the filter box 4 from top to bottom, the liquid medicine can pass through the filter holes of the filter plate 7, and the impurities in the liquid medicine can contact the filter plate 7, and slide along the inclined surface of the filter plate 7 under the flushing of the subsequent liquid medicine, and be intercepted by the interception part, so that the filter plate 7 is not easily blocked by impurities, thereby not easily affecting the passage of the liquid medicine;

[0029] A cleaning port 8 is provided on the filter box 4 and is equipped with an outer cover 9 for covering the cleaning port 8. When the outer cover 9 is opened, the impurities intercepted by the interception part can be cleaned through the cleaning port 8;

[0030] The present application adopts the design of the filter box 4. When the medicinal solution containing blood clots and necrotic substances passes through the filter box 4 from top to bottom, the medicinal solution can pass through the filter holes of the filter plate 7. Impurities in the medicinal solution can contact the filter plate 7 and slide along the inclined surface of the filter plate 7 under the flushing of the subsequent medicinal solution and be intercepted by the interception part, so that the filter plate 7 is not easily blocked by impurities, thereby not easily affecting the passage of the medicinal solution.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the cleaning port 8 is arranged at the top of the filter box 4, and the liquid inlet pipe 5 is installed on the outer cover 9. Such a design facilitates the cleaning of impurities intercepted by the interception part after the outer cover 9 is opened.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, one end of the outer cover 9 is hinged on the filter box 4, and the other end thereof is fixed to the filter box 4 by a buckle 10. This design prevents the outer cover 9 from being completely separated from the filter box 4, making it easy to open the outer cover 9 and fix it.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, a sealing gasket 11 is laid along the edge of the cleaning port 8. The sealing gasket 11 is a rubber gasket, which can be in conflict with the sealing gasket 11 when the outer cover 9 closes the cleaning port 8. Such a design can improve the sealing performance of the filter box 4 after the outer cover 9 is closed, so that the drug solution is not easy to seep out from the cleaning port 8.

[0034] like Figure 3 and Figure 4 As shown, in some embodiments, blocks 12 are constructed on the relative inner walls of the filter box 4, two intercepting parts are respectively constructed on the top of the two blocks 12, the filter plate 7 is movably constructed on the two blocks 12, and handles 13 are constructed on the connecting ends of the two filter plates 7. After opening the outer cover 9, the filter plate 7 can be lifted out of the cleaning port 8 together with the intercepting part through the handle 13 to facilitate cleaning of the intercepted impurities.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the interception portion includes an arc-shaped plate 14, the end of the arc-shaped plate 14 is connected to the filter plate 7, and the end thereof is in contact with the inner wall of the filter box 4, and the inner side of the arc of the arc-shaped plate 14 is away from the bottom of the filter box 4. The impurities intercepted by the filter plate 7 can be concentrated and accumulated on the inner side of the arc of the arc-shaped plate 14 to facilitate cleaning.

[0036] like Figure 3and Figure 4 As shown, in some embodiments, the end of the arc plate 14 is connected to a vertical plate 15, and baffles 16 are constructed at both ends of the vertical plate 15, and the baffles 16 are connected to the filter plate 7. The arc plate 14, the filter plate 7, the vertical plate 15 and the baffles 16 cooperate with each other to collect the intercepted impurities so that they are not easy to fall into the interior of the filter box 4 when the filter plate 7 moves upward.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, the connecting ends of the two filter plates 7 are located directly below the liquid inlet pipe 5. When the liquid medicine enters the filter box 4, it can pass through the two filter plates 7 more evenly under the action of the connecting ends of the two filter plates 7, so that the impurity interception amounts of the two arc plates 14 are similar, which is convenient for cleaning.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the bottom of the filter box 4 is symmetrically constructed with guide slopes 17, and the connecting pipe 6 is set at the lowest point of the two guide slopes 17. Such a design can guide the liquid medicine entering the filter box 4 to the greatest extent, making it difficult for it to remain inside the filter box 4.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
