Description

Detachable multi-interface venous kettle device

Technical Field

The utility model relates to a detachable multi-interface venous kettle device, and belongs to the technical field of medical appliances.

Background

The continuous kidney substitution therapy (continuous renal replacement therapy, CRRT) is a blood purification therapy with a continuous treatment time of 24 hours per day, can continuously remove various metabolites, toxins, inflammatory factors and the like in vivo, can regulate body fluid electrolyte and acid-base balance, protects and supports the functions of important organs, and is suitable for patients with various acute and chronic renal failure, severe pancreatitis, sepsis, infective shock, multiple organ failure and the like. Because CRRT has stable hemodynamics, higher solute clearance rate, well corrects internal environment disturbance and is favorable to characteristics such as nutrition support, at present, CRRT has been widely used in the treatment of various critical patients such as ward, intensive Care Unit (ICU), emergency rescue room, etc.. The unscheduled machine (dialysis machine) is a common problem in the CRRT implementation process, so that not only is the treatment target not completed, but also the treatment cost, manpower and material resources and the like are increased; currently, the main reason for unplanned off-line is from extracorporeal circulation coagulation.

In clinical work, there are many patients who need CRRT support, and anticoagulant drugs are not suitable to be used due to the critical nature of the disease of the patients, such as high risk of bleeding or coagulation breakdown, or the high coagulation state of the patients, in particular to the blockage of the coagulation of the venous pot of a dialysis machine. Venous kettles of dialysis machines are used to prevent air from entering the patient, where blood tends to stagnate, or form turbulence, and are a high-lying site for CRRT clotting. If the liquid level in the venous bottle is low, the mouth of the blood input end does not reach the liquid level of the blood in the venous bottle, and a 'gas-blood' contact surface is formed, so that coagulation can be promoted. If the liquid level in the venous pot is high, the air-blood contact surface can be avoided when the pipe orifice of the blood input end is buried below the liquid level of the blood, and the depth is extremely difficult to grasp, if the pipe orifice of the input end is buried too deeply, the blood at the upper end of the venous pot is in a relatively static state, and the possibility of aggregation of the blood at the upper end is increased. The CRRT pipeline commonly used in the market at present is directly connected with other pipelines at the upstream and downstream of the venous kettle section in a non-joint way, so that once the venous kettle is blocked, the blood of the whole extracorporeal circulation pipeline cannot be returned to a patient, and the blood is lost, and the lost blood volume reaches 200-250ml; in severe cases, the function of the vascular access may be affected and even the vascular access may be rendered inoperative. If CRRT treatment is needed to be continued, the whole set of consumable materials such as pipelines, filters and the like are needed to be replaced for a plurality of times, so that not only is the economic burden of a patient increased, but also the medical risks and doctor-patient contradiction are increased, and meanwhile, the workload and psychological pressure of medical staff are increased. Therefore, the technical problem that the blood of the whole extracorporeal circulation pipeline cannot be returned to the patient body and the blood is lost because the venous kettle section of the dialysis machine is easy to be blocked is needed to be solved in the technical field.
