Description

Dialysate pipeline joint for realizing adjustable potassium and calcium ion concentration of dialysate

Technical Field

The utility model relates to the technical field of medical equipment, more specifically the dialysate pipeline that is used for realizing dialysate potassium, calcium ion concentration adjustable connects that says so.

Background

The exchange of water and solute is carried out through the pellicle in the cerini dialyser cerini to patient's blood and dislysate among the hemodialysis treatment process, wherein correct the internal electrolyte disorder of patient and exchange the completion according to the solubility gradient between blood and dislysate through the electrolyte, the internal electrolyte level of patient can fluctuate in a great scope, the electrolyte concentration of dislysate is then according to the electrolyte condition that normal people's blood electrolyte level range was corrected again according to the general needs of hemodialysis patient and is formulated, it is fixed, along with the going on of hemodialysis, patient's blood electrolyte concentration can draw close up to reach the purpose of correcting internal electrolyte disorder gradually to normal scope. However, in clinical practice, some electrolyte concentrations in the dialysate are not suitable for the needs of the patient at the time, for example, the concentration of potassium ions in the dialysate is 2.0mmol/L, and sometimes the normal low limit of blood potassium concentration of the patient before hemodialysis treatment is less than 3.5 mmol/L, in this case, the hemodialysis treatment can not correct hypokalemia of the patient, but can also aggravate the reduction of the blood potassium and even endanger the life of the patient. The solution under the current conditions is: 1. the use of commercial dialyzates with higher potassium concentration, such as dialyzates with potassium ion concentration of 3.0mmol/L, is very rare at home and abroad, and the selectable potassium ion concentration of the dialyzates is very low, so if no patients exist in a period of time, the dialyzates are wasted due to the fact that the effective period is exceeded. 2. Some hospitals directly add potassium chloride injection into the A liquid of the concentrated dialysate to improve the potassium ion concentration in the dialysate, but the method has the possibility of dialysate pollution, in addition, the required amount of the added potassium chloride injection needs to be accurately calculated, which is possible only by professionals familiar with the performances of hemodialysis machines and dialyzates, in addition, different formulas of dialysate preparation systems used by different hemodialysis machines need to be calculated according to the change of the formulas, which is difficult to be realized in most hemodialysis rooms. In addition, the concentration of calcium ions in dialysate needs to be adjusted in clinic sometimes, the current solution at home and abroad is to produce commercial dialysate containing 1.25mmo/L, 1.5mmo/L and 1.75mmo/L of calcium ions, more than 90% of the dialysate containing 1.5mmo/L of calcium ions is used in clinical hemodialysis treatment at present, and if no patient needs to use the dialysate containing 1.25mmo/L and 1.75mmo/L of calcium ions within a period of time, the dialysate is overdue and wasted. The invention aims to realize free adjustment of potassium ions and calcium ions in dialysate by adding a dialysate pipeline joint on the premise of not changing the main structure of a hemodialysis machine, overcomes the defects of the conventional method, and has no similar method at home and abroad.
