The invention belongs to the technical field of coal mine underground individual protection, and particularly relates to a mine underground multi-working-condition composite phase change material cooling garment which comprises a cooling garment body, a plurality of cold storage bag side pockets and a plurality of cold storage bags, and the cold storage bag side pockets are arranged at the chest position, the abdomen position and the lower portion of the back of the cooling garment body respectively. The cold storage bag side pocket is used for containing a cold storage bag, and a composite phase change material is packaged in the cold storage bag. The invention further provides a manufacturing method of the mine underground multi-working-condition composite phase change material cooling clothes. The thermal comfort and safety of operators in the high-temperature environment are improved, on-demand regulation and control of the cooling efficiency are achieved through modular design, the effective cooling time is remarkably prolonged, and energy consumption and maintenance cost are reduced. The cooling suit can stably operate under the continuous underground working condition, has good environmental adaptability and reliability, is suitable for different actual working conditions, and has important popularization value and application prospects.

This invention discloses a method, apparatus, device, and storage medium for controlling a heart pump. The method includes: acquiring a target blood flow value of a target object; inputting the target blood flow value into a pre-trained target preload prediction model to obtain a preload prediction value; and adjusting the rotational speed of the target heart pump based on the preload prediction value and a preset preload reference standard. This invention addresses the safety issues inherent in prior art where heart pump rotational speed is controlled by collecting blood pressure and blood flow signals. It allows for adjustment of the heart pump rotational speed based on the object's preload prediction value, thereby improving the safety of the heart pump rotational speed control process.
