Paper feeder capable of automatically feeding paper for electrocardiograph

Abstract

The invention discloses a paper feeder capable of automatically feeding paper for an electrocardiograph. The paper feeder comprises a paper feeding box, a rotary drum box and a connecting box. An upper cover is mounted at the position of an opening in the upper end of the paper feeding box, first baffles are arranged on the left side and the right side in the paper feeding box, second baffles arearranged below the first baffles, telescopic assemblies are mounted on the outer sides of the first baffles and the second baffles, the rotary drum box is mounted below the paper feeding box, the leftside of the rotary drum box is connected with a discharge drum box, a side cover is mounted at the position of an opening in the left side of the discharge drum box, a boss is mounted on the inner bottom face of the rotary drum box, a distance measuring sensor is inlaid into the boss, paper drums are arranged between the adjacent positions of the boss, the first baffles and the second baffles, the connecting box is mounted on the right side of the rotary drum box, and a rotary rod is mounted in the corner of the joint of the connecting box and the rotary drum box. Through the cooperation of the distance measuring sensor and a controller, paper is automatically replaced and fed, and the paper feeder is high in intelligence degree and higher in practicality.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a paper feeder for an electrocardiogram machine that can automatically feed paper. Background technique [0002] The electrocardiogram function can automatically record the bioelectrical signal (cardiac signal) generated by the myocardial excitement when the heart is active, and is a medical electronic instrument commonly used in clinical diagnosis and scientific research. Before the heart beats, the myocardium is first excited, and a weak electric current is generated during the exciting process, and the electric current is conducted to various parts through the human body tissue. Due to the different tissues of different parts of the body and the different distances between each part and the heart, various parts of the human body surface show different potential changes. The relationship between the surface potential and time generated by the electrical activity in the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a paper feeder for electrocardiograph machines that can automatically renew paper, which solves the problem that it is inconvenient to remind medical staff when the printing paper inside the electrocardiogram machine on the market is about to run out, which makes it difficult for medical staff to replace it in time. Printing paper affects the normal use of the electrocardiogram machine, and the existing electrocardiogram machine has a small internal storage capacity for printing paper. Frequent paper changes increase the daily workload of medical staff, and the existing electrocardiogram machine needs to manually replace the printing paper. Problems that are inconvenient to use
