The invention discloses an automatic prefilling method for a medical injection pump and relates to the technical field of medical devices. According to the method, the minimum thrust F0 or the minimum pressure P0 of an injector and the maximum clearance L0 or the pulse total number C0 of the injection pump are measured in advance; in the starting operation initial stage of the injection pump, the pulse number C1 of a stepping motor is measured, or the quasi-movement distance L1 of a push rod is calculated; the thrust F1 or the pressure P1 of the push rod of the injection pump to the injector is detected; and according to the magnitude relationship between C1 and C0 or L1 and L0, and between F1 and F0 or P1 and P0, whether compressing of the mechanical clearance of the injection pump is completed or not is judged, accordingly the operation speed of the injection pump is modified, and the automatic prefilling procedure is completed. The manual prefilling operation process is omitted, the operation procedure of the injection pump is simplified, the prefilling time is shortened, medicine liquid can be injected into a patient timely, the using efficiency of the injection pump is improved, and medicine waste is further reduced.

The invention provides a heat collection evaporator with a built-in passage. The heat collection evaporator comprises a heat preservation shell and a sealed shell, wherein the sealed shell is arranged in the heat preservation shell; a heat preservation layer is arranged between the bottom part of the sealed shell and the heat preservation shell; the upper part of the sealed shell is provided with a glass cover plate; a capillary structure layer and a solar heat collection panel which covers the capillary structure layer are arranged in the sealed shell; a steam collection groove and a working medium backflow groove are prefabricated in the capillary structure layer; a working medium entering the capillary structure layer can be evaporated after heat is absorbed by the solar heat collection plate, so that the heat can be supplied. The invention also provides a solar water heater with the heat collection evaporator, wherein the heat collection evaporator and a water storage tank are communicated through a loop pipeline. According to heat collection evaporator and the solar water heater, provided by the invention, the requirement of mid-rise buildings on the whole attractiveness can be met; meanwhile, power-free cycle of the working medium can be realized by utilizing the capillary action of the capillary structure, the installation of the whole solar water heater is simple, the working medium can be driven without other power, and the daily demands of people can be met.

The invention provides a medicine injection device for agriculture and forestry maintenance, which relates to the technical field of agriculture and forestry maintenance, and includes: a bracket, a roller, a lifting structure, a medicine injection structure and a drilling structure. Rollers are installed at the four corners of the bottom side of the bracket, and the lifting structure is installed On the top side of the support, the drilling structure is arranged on the top side of the lifting structure, and the injection structure is arranged between the lifting structure and the drilling structure. By setting the lifting structure, under the action of the first cylinder, the first shearing structure is changed. The angle between the force bar and the second shear bar can realize the multi-height injection operation. By setting the injection structure and the drilling structure side by side, the drug can be injected in time after the drilling. For operation, it is possible to tilt the hole at multiple angles to meet the needs of the operation. At the same time, a scale is set to grasp the depth of the hole when drilling, so as to achieve better maintenance purposes.
