Abstract

The invention provides a pedal device and an injection pump comprising the pedal device. The pedal device comprises a horizontal plate, an inclined plate connected with one end of the horizontal plateand obliquely arranged in a manner of forming an included angle theta with the horizontal plate, at least one elastic pedal part arranged on the horizontal plate in the area of the included angle theta, and at least one elastic foot top part arranged on the inclined plate. The distance between the joint of the horizontal plate and the inclined plate and the foot top part is not smaller than thatbetween the joint and the pedal part, and theta is greater than 0 degree and smaller than 90 degrees. The signal output ends of the pedal part and the foot top part can be respectively connected withthe signal input end of an external device. According to the pedal device, the two control modes can be triggered only by operating the pedal part downwards through the tiptoe and operating the foot top part upwards through the tiptoe without changing the position of the foot, the occupied space is small, and the arranged pedal part and foot top part are very easy to distinguish in the using process and are not prone to being stepped by mistake.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pedal device and a push injection pump comprising the pedal device. Background technique [0002] Ultrasound-guided descending nerve block is a trend in the development of anesthesiology technology, and the use of ultrasound can better meet the requirements of modern medicine that are precise, controllable, and individualized. In normal clinical work, it is found that it is basically impossible for one person to complete the nerve block under the guidance of ultrasound. The main reason is that the operator controls the ultrasound probe with his left hand and the nerve block needle with his right hand. The withdrawal and injection operations can no longer be performed. At this time, we need special personnel to assist the withdrawal and injection operations of the syringe, which is very inconvenient to use.
