Preset drainage assembly for abdominal cavity perfusion

Abstract

The invention provides a preset drainage assembly for abdominal cavity perfusion. The preset drainage assembly comprises a reserved pipe fixed to the abdominal cavity of a patient and a perfusion connecting pipe penetrating through the reserved pipe to conduct abdominal cavity perfusion, an inflation dredging structure is arranged at the inner end, inserted into the abdominal cavity, of the reserved pipe, and the inflation dredging structure comprises an inflation expansion cavity arranged around the inner wall of the reserved pipe. A plurality of fan-shaped overturning pieces made of silica gel materials are arranged on the inner wall of the inner end of the reserved pipe, the fan-shaped overturning pieces are spliced to form a silica gel sealing plate for sealing the inner end of the reserved pipe, the annular elastic sealing skin is tightly attached to the fan-shaped overturning pieces, and after the inflation expansion cavity is inflated, the fan-shaped overturning pieces are pushed to overturn downwards and protrude out of the inner end of the reserved pipe, and the fan-shaped tip ends of the fan-shaped overturning pieces are used for dredging the inner end of the plugging reserved pipe. Before perfusion, the inflation expansion cavity is inflated and deflated, so that the fan-shaped turnover pieces are pushed to turn over downwards, dredging of the blocked pipe opening is achieved, operation is easy and convenient, and no damage is caused to the wound of a patient.

Description

technical field [0001] The invention relates to peritoneal perfusion therapy in cancer treatment methods, in particular to a pre-set drainage assembly for peritoneal perfusion. Background technique [0002] Peritoneal perfusion chemotherapy, referred to as peritoneal perfusion, is one of the common chemotherapy methods for the treatment of advanced tumors in the pelvis and abdominal organs. It is generally divided into hyperthermic perfusion and conventional perfusion. The principle is simple. After that, chemotherapeutic drugs or drugs for eliminating peritoneal effusion are instilled into the peritoneal cavity through the drainage tube; different from hot perfusion, conventional perfusion is to inject the drug into the abdominal cavity, and then bind the drainage tube so that the drug remains in the patient's peritoneal cavity for a period of time. It is about 24 hours, so that the patient can fully absorb the drug. In order to promote the absorption of the drug, during th...

Problems solved by technology

[0004] In order to solve the problem that the existing drainage tube for peritoneal perfusion is difficult to dredge after being blocked by peritoneal effusion, the present invention provides a preset drainage assembly for peritoneal perfusion, which includes a reserved tube fixed in the patient's abdominal cavity And the perfusion connecting tube that passes through the reserved tube for peritoneal perfusion, by setting an inflatable expansion cavity and a fan-shaped flip piece at the inner end of the reserved tube, take out the perfusion connecting tube after perfusion, and the fan-shaped flip piece will seal the inner end of the reserved tube, even if peritoneal effusion occurs The reserved tube is solidified and blocked. Before the next perfusion, inflate the inflatable expansion chamber, thereby pushing the fan-shaped flip piece to turn down, realizing the dredging of the blocked tube mouth. The operation is simple and convenient, and will not cause damage to the patient's wound. does not cause discomfort to the patient
