Intussusception resetting system and method

Abstract

The invention discloses an intussusception resetting system and method. The system comprises intussusception resetting equipment and a disposable consumable structure; the disposable consumable structure is provided with a liquid inlet part, a waste liquid discharge part, an insertion part and a pressure monitoring connection part; and the intussusception resetting equipment comprises an automaticliquid inlet device capable of pumping perfusion liquid, a pressure control device used for setting the maximum perfusion pressure of perfusion liquid during intussusception resetting and monitoringthe perfusion liquid pressure in real time, and a flow speed adjusting device used for adjusting the perfusion flow speed of the perfusion liquid, an active pressure relief device can be used for reducing the perfusion liquid pressure, and main control system used for outputting a main control signal. The method is applied to the intussusception resetting system. Through system linkage control such as perfusion liquid speed control, perfusion liquid pressure control and active pressure relief control, the convenience and real-time performance of reset pressure control in intussusception can beimproved, the burden of doctors is reduced, and the safety of patients is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of medical devices, in particular to an intussusception reduction system and an intussusception reduction method applied to the system. 【Background technique】 [0002] Acute intussusception is a common surgical emergency in infants and young children, mainly concentrated in infants aged 2 to 36 months, and the incidence rate of male infants is twice that of female infants, that is, the probability of three to one. It refers to a condition in which one section of intestine nests inside another, forming a folded shape like a straight telescope when stored. Although intussusception can occur in any part of the intestinal tract, the junction of the ileum and colon is the most common location for intussusception. The vast majority of intussusception is that the proximal bowel intussulates the distal bowel, because the peristalsis of the bowel pulls the proximal bowel to the distal bowel, so the proximal bowel ...

Problems solved by technology

It uses a pointer pressure gauge to measure the pressure of the fluid in the pipeline, which also has errors in manual interpretation and the accuracy generally can only reach about ±10% of the range; the accuracy of the mechanical pressure regulating and limiting valve is also low, resulting in excessive The reliability of pressure protection decreases; and the pressure gauge and pressure regulating and limiting valve must be discarded after one-time use to avoid cross-contamination, which is not in line with economic principles and increases medical costs

[0007] In addition, another disadvantage of the patented method is that the operating doctor must rely on manpower to squeeze the water injection balloon of the one-way valve to perfuse the intestine with liquid; Physicians are overburdened

[0008] Using liquid intussusception reduction surgery under ultrasound image monitoring, the doctor should pay close attention to the changes of the concentric circle sign on the transverse section of the intussusception and the peninsula sleeve sign on the longitudinal section. And focus on perfusion pressure monitoring, perfusion fluid injection and other work, so that doctors face multiple physical and mental loads, reduce the agility of response, thus affecting the success rate and safety of reduction surgery
