Medical single-cannula anti-blocking drainage tube for hyperthermic intraperitoneal chemotherapy based on replacement of inner tube

Abstract

A medical single-cannula anti-blocking drainage tube for hyperthermic intraperitoneal chemotherapy based on replacement of an inner tube belongs to the field of medical instruments. According to the technical scheme, a single-cannula channel is constructed to guarantee the circulating flow requirement of hyperthermic intraperitoneal chemotherapy, and when a pipeline is blocked, blockages in the inner tube are removed in time through the technical method of replacing the inner tube through sterile operation. In addition, damage to the machine body is small in the inner tube replacing process, and the operation is easy. In addition, the replacement of the inner tube is generally performed before the hyperthermic intraperitoneal chemotherapy is performed such that the occupational exposure ofmedical personnel to chemotherapeutic drugs is avoided. Besides, on the premise that the hyperthermic intraperitoneal chemotherapy is carried out smoothly and the clinical treatment effect of a tumorpatient is improved, the cost of the technical scheme can be greatly reduced.

Description

technical field [0001] The invention or the practical technical solution belongs to the field of medical devices, and relates to a medical single sleeve anti-blocking drainage tube for hyperthermic perfusion chemotherapy in the abdominal cavity based on the replacement of the inner tube. Background technique [0002] Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is an emerging adjuvant therapy for abdominal malignant tumors with unique curative effect and can significantly improve the survival time of patients. It is mainly used in the prevention and treatment of patients with peritoneal seeding metastasis of abdominal malignant tumors such as gastric cancer and colorectal cancer and concurrent malignant ascites. Its advantage is that it has the mechanical lavage effect of local chemotherapy, hyperthermia and large-volume chemotherapy solution on the peritoneal cavity, has the advantages of pharmacokinetics and fluid dynamics, and makes full use of the synergistic effect...

AI Technical Summary

Problems solved by technology

Zhu Xiaohui et al [2] retrospectively analyzed the clinical case data of more than 1,200 patients undergoing intraperitoneal hyperthermic perfusion chemotherapy. Her research found that the most important reason for HIPEC operations not to go smoothly is pipeline blockage; she believes that pipeline blockage The most common reason is that a large amount of interstitial fluid, some blood and exfoliated tissue exuded from the wound after abdominal surgery. These interstitial fluid and blood contain a large amount of prothrombin complex and cellulose-like substances, which are easy to form coagulation; The patient is less active, and the position of the drainage tube is relatively static for a long time. Eventually, the lumen of the drainage tube will be blocked or the drainage will not be smooth due to blood clots, exfoliated tissue and omentum deposition.
