Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a mixing bag for quick-mixing crystalloid depressant solution. Background Technology
[0002] Currently, in cardiac transplant donor retrieval surgery, it is necessary to perfuse the patient's heart with cardioplegic solution. Cardioplegic solution perfusion devices are widely used in fields such as extracorporeal circulation. During cardiac surgery, perfusing the patient's heart with a lower-temperature cardioplegic solution using a cardioplegic solution perfusion device can ensure that the patient's myocardium is kept at a lower temperature, reduce myocardial oxygen consumption, improve the stability of the surgery, and restore the heart temperature to normal body temperature before surgery. The cardioplegic solution is usually prepared by mixing 30 mL of high glucose, 24 mL of NaHCO3, 18 mL of KCl, and 1425 mL of compound sodium chloride solution.
[0003] Since the acquisition of heart donors outside the hospital is mostly random, the preoperative supplies must be prepared accurately. Currently, when preparing the cardioplegic solution, the operator needs to inject the corresponding solutions in sequence according to the above ratio. This process involves many injections, is cumbersome, and is prone to errors in the ratio. In addition, the solution needs to be stored at low temperature after preparation. The entire preparation process is complicated and cannot be carried around. When using heart donors outside the hospital, it is not possible to prepare the solution quickly, which affects the acquisition of heart donors. Therefore, we propose a mixing bag for rapid preparation of crystalloid cardioplegic solution. Utility Model Content

This involves numerous injections, cumbersome operation, and is prone to errors in the proportions. Furthermore, the prepared solution requires low-temperature storage, making the overall preparation process complex and impractical to carry. This hinders the rapid preparation of cardiac arrest fluid when used by donors, thus affecting the acquisition of donor hearts.
