Example Embodiment

[0033]Example 1

[0034]A CRRT pipeline replacement method, including the following steps:

[0035]Step1: Confirm the patient’s identity information, view the case, summarize the cause of the blood return, observe the mental state, ask simple questions about their own condition, and use professional equipment to detect;

[0036]Step2: Sterilize the deep venous cannula according to the aseptic operating procedures, prepare a 5ml syringe for indwelling 2ml glycolic water, a 20ml empty syringe and a V tube;

[0037]Step3: Pre-flush the pipeline, adjust the patient's position and the position of the catheter;

[0038]Step4: Connect one end of the hemofiltration tube to the corresponding end of the patient's deep venous catheter, turn on the blood pump, the blood flow speed is not higher than 100ml / min, start anticoagulation, and take a sample at the sampling port when the blood is drained to the filter , The blood is drained to the end of the V tube, the pressure sensor senses the signal, the blood pu...

Example Embodiment

[0055]Example 2

[0056]In view of the specific operating principle of the method of the present invention, the percutaneous puncture cannula is used in Step 4, and the femoral vein is selected for venous catheterization, which is to ensure the compression hemostasis effect and reduce the incidence of hematoma. At the same time, the puncture is more convenient, with low technical requirements In the plan, Step11 sealing method is to use normal saline first and then heparin solution. The tip of the catheter is wrapped with a sterile treatment towel. In the plan, Step4 prevents coagulation can be diluted. The pre-dilution is mixed with replacement fluid and arterial blood before entering The filter prolongs the service life of the filter. The post-dilution adopts the replacement liquid and the blood purified by the filter to mix and return to the body, and reduces the sampling port for blood collection and administration, does not easily turn off the blood pump, and strengthens monitorin...

Abstract

The invention discloses a CRRT pipeline replacement method. The CRRT pipeline replacement method comprises the following steps: Step 1, confirming identity information of a patient, checking a case ofthe patient, summarizing blood return reasons, observing the mental state of the patient, inquiring a problem about a simple self condition of the patient, and performing detecting by using a professional instrument; Step 2, disinfecting a deep vein cannula according to sterile operation instructions, and preparing a 5ml injector to retain 2ml of glycyl water, a 20ml empty injector and a V tube;Step 3, performing pipeline pre-flushing, and adjusting the body position of the patient and the position direction of a catheter; and step 4, connecting one end of a blood filtering pipeline with thecorresponding end of a deep vein indwelling catheter of the patient, starting a blood pump, controlling the blood flow speed to be not higher than 100ml/min, starting anticoagulation, performing sampling at a sampling port when blood is sparsely guided to a filter, sparsely guiding the blood to one end of the V tube, sensing a signal by a pressure sensor, closing the blood pump and connecting oneend of the V tube of the deep vein indwelling catheter. The CRRT pipeline replacement method is easy and convenient to operate, the treatment progress of the patient can be kept, no extra adverse effect is caused to the physical condition of the patient, and use is safe.

Description

technical field [0001] The invention relates to the technical field of CRRT pipeline replacement, in particular to a CRRT pipeline replacement method. Background technique [0002] CRRT continuous renal replacement therapy is defined as a blood purification treatment technique that continuously and slowly removes water and solutes through extracorporeal circulation blood purification to replace kidney function. Compared with ordinary hemodialysis, CRRT prolongs the treatment time of blood purification and reduces It improves the treatment efficiency per unit time, minimizes the impact of solute concentration and volume changes in the blood on the body, and uses high-permeability and biocompatibility filters to provide extremely important internal stability for the treatment of critically ill patients. There are three main methods of solute removal in CRRT: diffusion, convection, and adsorption. Different treatment modes have different removal mechanisms. Hemodialysis is main...
