Magnetic field-guided peritoneal dialysis catheter positioning, repositioning, and catheter passing device

Abstract

The invention discloses a peritoneal dialysis pipe positioning, resetting and conducting device based on a magnetic field guide. The peritoneal dialysis pipe positioning, resetting and conducting device comprises an intubation pipe part one end of which can be inserted into a peritoneal dialysis pipe and an external part arranged outside a human body, wherein the intubation pipe part comprises a magnetism end head which can be inserted into the peritoneal dialysis pipe and a first spring; one end of the first spring is fixedly connected with one end of the magnetism end head, the outer surface of the magnetism end head is provided with a medical titanium layer, the other end, which approaches to the first spring, is provided with a regulation positioning mechanism which is used for regulating the length of the intubation pipe part which is inserted into the peritoneal dialysis pipe and can position the intubation pipe part after regulating, and the regulation positioning mechanism is arranged outside the peritoneal dialysis pipe; the external part is provided with a magnet which can generate a magnetic field action with the magnetism end head. The peritoneal dialysis pipe positioning, resetting and conducting device provided by the invention has the advantages that the structure and design are reasonable, the operation is convenient, the using effect is good, the positioning, resetting and conducting of the peritoneal dialysis pipe are effectively realized, and a problem that the positioning and regulation device of the existing peritoneal dialysis pipe can generate the great influence so as to influence the diagnoses and treatment at the next step is solved.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic field-guided peritoneal dialysis tube positioning, reset, and tube-passing device. Background technique [0002] Chronic renal failure is the progressive progression of various chronic kidney diseases, causing irreversible loss of nephrons and renal function, resulting in clinical syndrome characterized by retention of metabolites, disturbance of water, electrolyte and acid-base balance, and endocrine disorders. The advanced stage of renal failure is uremia. [0003] With the development of society and the emergence of an aging population, the incidence of chronic kidney disease and the chronic renal failure caused by it has increased year by year in the world in recent years. There are about 2.2 million to 2.7 million people with end-stage renal failure in the world each year who receive dialysis. The number of patients treated is increasing at an annual rate of 10% to 12%. In re...

Problems solved by technology

(3) At present, the commonly used medical magnets are NdFeB magnets with the highest unit magnetism. This magnet is suitable for being stored in a ventilated and dry room. It is easy to rust the magnet if it is placed in an acidic, alkaline, organic solution, water, or high-temperature and humid environment for a long time. Powdered demagnetization of shedding magnets

[0008] Second, the impact on patient diagnosis: patients with chronic renal insufficiency have a very high incidence of cardiovascular system diseases. Although various renal replacement therapies can maintain the life of patients, a large part of patients have not yet developed to the point of need. Death on dialysis or while receiving renal replacement therapy from any cause, most commonly due to a cardiovascular event

Due to the high chance of cardiovascular disease and cerebrovascular disease in patients with severe renal impairment, once these patients have the above-mentioned related diseases or have other systemic diseases and need further examination, because the contrast agent is not suitable for use, the next step should be carried out. Diagnosis and treatment, nuclear magnetic resonance examination is very important for these patients, but if there are metals or objects containing magnetic fields in the body to prevent nuclear magnetic reaction, nuclear magnetic resonance cannot be carried out, which will cause great harm to the further diagnosis and treatment of these patients Difficult, even very serious consequences

For example, once a patient has consciousness problems and suspects that it is a brainstem lesion, whether it is hemorrhage or ischemic lesion, the diagnosis must be confirmed, because the treatment is completely different, often because the lesion may be small, CT examination sometimes cannot confirm the lesion

[0009] Third, the impact on the patient's treatment: If the patient has a stent or a pacemaker in the body, the magnet will affect it. If a magnetic object is placed in the body for a long time, it will have a greater impact. Magnetic peritoneal dialysis tubing cannot be used

In addition, a magnetic peritoneal dialysis tube is placed in the patient's body. Once a myocardial infarction, severe arrhythmia, or severe stenosis of the blood vessel occurs, the stent or pacemaker cannot be placed, which will endanger the patient's life, or the peritoneal dialysis must be pulled out. Tube
