Electrocardiograph paper shearing device

Abstract

The invention discloses an electrocardiograph paper shearing device which comprises an operating table. Balance plates are arranged on the upper surface of the operating table, rollers are arranged inthe balance plates, buffer grooves are formed in the balance plates, limit clamping plates are arranged on two sides of each buffer groove, a base is welded at the bottom of the operating table, supporting frames are welded on two sides of the base, a beam is welded at the top of the supporting frames, an upper cylinder is arranged at the top of the beam and connected with a bearing plate througha hydraulic telescopic rod, an auxiliary support is arranged at a joint of the bearing plate and the hydraulic telescopic rod, lower cylinders are arranged at two top sides of the bearing plate, second shearing knives are arranged at the bottoms of the lower cylinders, a first shearing knife is arranged at the bottom center of the bearing plate, and a spring pipe is arranged in the first shearingknife. The shearing device is simple and reasonable in overall structure design and safe and stable to run and has high practicability, and multi-position shearing effects are achieved.

Description

technical field [0001] The invention relates to the technical field of electrocardiographic drawings, in particular to a cutting device for electrocardiographic drawings. Background technique [0002] Electrocardiography (ECG or EKG) is a technology that uses an electrocardiogram machine to record the electrical activity changes generated by each cardiac cycle of the heart from the body surface. The myocardial cell membrane is a semipermeable membrane. Cation, the same number of negatively charged anions are arranged in the membrane, and the potential outside the membrane is higher than that inside the membrane, which is called a polarized state. In the resting state, since the cardiomyocytes in all parts of the heart are in a polarized state, there is no potential difference, and the current record The potential curve traced by the instrument is straight, which is the equipotential line of the body surface ECG. When cardiomyocytes are stimulated by a certain intensity, the...

Problems solved by technology

[0003] However, there are some shortcomings in the existing electrocardiographic drawing cutting device during use. The cutting effect for the electrocardiographic drawing is relatively simple, and only a single cutting operation can be realized, which cannot meet more cutting requirements.
