Multi-channel medical infusion system

Abstract

The invention provides a multi-channel medical infusion system which comprises a liquid storage container, multiple liquid catheters, a control valve and a peristaltic pump; the peristaltic pump comprises a machine case, a display screen arranged on the surface of the machine case, a switch, a peristaltic pump head and a peristaltic pump tube arranged in the peristaltic pump head, and the output end of the peristaltic pump tube is provided with a check valve and Luer tapers. The multi-channel medical infusion system is used for an endoscopic physician when gastrointestinal endoscope diagnosis and treatment are conducted, assistance of an assistant is not needed, the labor cost is reduced, and the communication troubles between the endoscopic physician and the assistant are reduced; the endoscopic physician can conduct cleaning and targeted dyeing on alimentary canals according to the needs, operation is continuous, easy and convenient, the time is saved, the application and promotion of a pigment endoscopy are convenient, and the multi-channel medical infusion system is especially suitable for primary hospitals and is favorable to discovery of an early digestive cancer; the consultation hours are significantly reduced, the operation troubles are omitted, the compliance of a patient is improved, and the uncomfortable feeling of the patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical and health care, and in particular relates to a perfusion system for various liquids during gastrointestinal endoscope diagnosis and treatment. Background technique [0002] my country is one of the countries with a high incidence of esophageal cancer and gastric cancer, with new cases and deaths exceeding 40% of the world figures for the same period. The 5-year survival rate of early esophageal cancer, gastric cancer and colorectal cancer exceeds 90%, but the early diagnosis and treatment rate in my country is currently low, such as the diagnosis and treatment rate of gastric cancer is less than 10%, far lower than Japan (70%) and South Korea (50%) , "China Cancer Prevention and Control Plan Steel Summary (2004-2010)" clearly pointed out that early detection, early diagnosis and early treatment of cancer are the main strategies to reduce mortality and improve survival rate.

The 5-year survival rate of early esophageal cancer, gastric cancer and colorectal cancer exceeds 90%, but the early diagnosis and treatment rate in my country is currently low, such as the diagnosis and treatment rate of gastric cancer is less than 10%, far lower than Japan (70%) and South Korea (50%) , "Chinese Cancer Prevention and Control Plan Steel Essentials (2004-2010)" clearly pointed out that early detection, early diagnosis and early treatment of cancer are the main strategies to reduce mortality and improve survival rate

[0003] Gastrointestinal endoscopy is the most commonly used and most effective method for the examination of gastrointestinal diseases, but ordinary endoscopy does not have obvious characteristics for early cancer, and it is easy to cause a certain degree of missed diagnosis and misdiagnosis

Fluorescence endoscopy, magnifying endoscopy, confocal endoscopy and electronic chromoendoscopy are effective means to detect early cancer, but they are expensive

Chromoendoscopy is based on routine endoscopy, spraying pigment dyes onto the surface of the mucosa to be observed, so that the contrast between the lesion and the normal mucosa is more obvious, which is helpful for the identification of lesions and the accuracy of biopsy, and improves the accuracy of biopsy. The positive rate of early cancer can be judged more accurately, such as the accuracy rate of Lugol's iodine staining in diagnosing esophageal cancer and precancerous lesions is 95.2%. The most important thing is that the pigments (Lugol's iodine solution, indigo carmine, acetic acid, etc.) are easy to configure, do not need to add expensive endoscopic accessories and endoscopic equipment, and do not increase the pain of patients. Mucous membrane cleaning and staining are seldom performed in practice, and the main problems are as follows: (1) The professional operation of assistants is required, and cooperation and constant communication are required during the inspection process, which distracts the attention of endoscopists; Or there is a lot of blood or excrement, and a large amount of cleaning solution is required. Sometimes the endoscopist needs to add dye or combined dye, so the assistant has to go back and forth many times, use multiple syringes to operate, and the fluid replacement or fluid replacement must be interrupted without interruption. The operation is very laborious and time-consuming; (3) directly using the syringe, the flow rate and flow rate mainly depend on the experience and feeling of the assistant, which often leads to a longer perfusion time and a large amount of perfusion liquid, which increases the discomfort of the patient. Excessive fluid can worsen the patient's nausea and vomiting
