The invention provides injection equipment and a pushing injection device. The injection equipment comprises a power mechanism, a transmission mechanism, a pushing injection mechanism and a speed change mechanism. The power mechanism is used for storing mechanical energy and generating rotation kinetic energy through the mechanical energy. The transmission mechanism is in transmission connection with the power mechanism. The injection mechanism is in transmission connection with the transmission mechanism, so that the injection mechanism can push the injector for injection. The speed change mechanism is in transmission connection with the transmission mechanism and used for controlling the moving speed of the injection mechanism. According to the injection equipment and the push injection device, automatic injection can be achieved under the condition of no electric power, operation is easy, the production cost is low, and carrying and maintenance are convenient. Besides, the moving speed of the injection mechanism is controlled through the speed change mechanism, so that the injection mechanism can push the injector to perform injection at a stable and slow speed, and the stability and safety of the injection equipment and the injection device are improved.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to an injection device and a push injection device. Background technique [0002] With the continuous development of medical technology, material technology, and mechanical technology, the medical industry's requirements for efficiency and quality have also increased, especially in terms of reducing the labor intensity of nurses and reducing the probability of errors during clinical treatment. Technological innovation. In order to reduce the labor intensity of nurses and the probability of errors during the treatment process, traditional injection devices use push injection pumps to assist in the completion of drug injection. However, due to the problems of battery power supply, bulky volume and inconvenient use and setting of traditional injection devices, it is inconvenient to use in environments such as out-of-hospital first aid or power outages.
