Embodiment Construction
[0041] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, only to illustrate the present invention, not to limit the protection scope of the present invention.
[0042] Double lumen central venous catheter and line preparation
[0043] Select the patient's internal jugular, subclavian or femoral vein to puncture a double-lumen central venous catheter, taking internal jugular vein catheterization as an example ( figure 1 ), the lateral drainage hole (103) draws out or reinfuses blood through the thicker lumen, and the tip end hole (102) injects diluent or medical solution into the vein through the thinner lumen, and fixes it with sutures. Wings (104) are secured to the patient's skin, holding the catheter in place. The supporting pipelines and monitoring and alarming accessories need to be placed on the host ( figure 2 ) and the control panel ( image 3 ). Connect the blood line branch (105) and the liqui...

The invention discloses a normovolemic dilution autoblood collection and reinfusion system and a normovolemic dilution autoblood collection and reinfusion device. The system is composed of a pipeline system, a dynamic system, a monitoring and alarming system, a blood-storage system and a computer control platform. When the system works, autoblood evenly blended with anticoagulation is stored in a blood-storage bag, at the same time diluent is infused in a blood vessel, and thus the purposes of blood sampling and hemodilution are achieved; when needed, the stored autoblood is infused back to a patient, and thus the purpose of reducing loss of hemoglobin is achieved. The system is controlled and operated by a computer, the monitoring and alarming system is arranged in the system, and thus safe operation is guaranteed. The dynamic system in the system can be controlled independently to conduct liquid infusion, and a pressure monitoring device can supply pressure data. The normovolemic dilution autoblood collection and reinfusion device is divided into a main engine and a control panel and is composed of a pump component, a mentoring component, a pipeline control card component, a control panel and a table. By means of the normovolemic dilution autoblood collection and reinfusion system and the normovolemic dilution autoblood collection and reinfusion device, normovolemic dilution autoblood collection and reinfusion can be performed automatically and safely, the workload of doctors is reduced, efficiency is improved, risk is avoided, and further the normovolemic dilution autoblood collection and reinfusion system and the normovolemic dilution autoblood collection and reinfusion device can be used as a infusion control platform and for pressure monitoring.
Description
technical field [0001] The invention relates to a system and a related device for completing autologous blood collection and reinfusion by means of isovolumic dilution, and the system can be used simultaneously to manage and control central venous infusion. Background technique [0002] Clinical use of blood mainly involves autologous blood and allogeneic blood. Transfusion of allogeneic blood may bring many problems to patients, such as allergies, fever, disease infection, etc. Doctors, patients, and family members all hope to avoid or reduce transfusion of allogeneic blood. This has long been an important topic of discussion and research in the medical community. clinical question. At the same time, the amount of bleeding and transfusion of allogeneic blood is one of the important criteria for evaluating the level of medical treatment. Less application of allogeneic blood usually indicates better medical technology and comprehensive medical management. In addition, allog...
