Wrist strap type mobile electrocardiograph

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a wrist strap type mobile electrocardiograph which comprises an electrocardiograph and a fixing unit. Thefixing unit comprises a shell, a first wrist strap, a second wrist strap, a pressing block, a first clamping block, a second clamping block, a third clamping block and a sliding block. According to the wrist strap type mobile electrocardiograph, the size of the wrist strap can be freely changed according to wrists of different sizes, so that the wrist strap type mobile electrocardiograph is suitable for being worn by different people, meanwhile, the redundant wrist strap is stored in the corresponding wrist strap after the position is fixed, and the situation that the redundant wrist strap makes contact with other objects to drive the wrist strap type mobile electrocardiograph to fall off the wrist is avoided; when the wrist moves, the contact surface of the wrist strap type mobile electrocardiograph and the wrist is tighter, so that the electrocardiograph is accurate in measurement, the physical state of a user can be reflected more accurately, and the contact part of the wrist straptype mobile electrocardiograph and the wrist is not prone to sweating, and odor is not generated; the wrist strap type mobile electrocardiograph is prevented from being soaked by sweat when making contact with the wrist, and the skin is prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a wristband-type mobile electrocardiograph. Background technique [0002] The electrocardiograph can automatically record the bioelectrical signal (ECG 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. In China, according to the number of output channels of the recorder, it is generally divided into: single-channel, three-channel, six-channel and twelve-channel ECG machines. [0003] There are also some technical solutions for wristband-type mobile electrocardiographs in the prior art, such as a Chinese patent with application number CN202010791829.3, which includes a portable electrocardiograph body and a fixing device fixed at the lower end of the portable electrocardiograph body , the fixing device includes a first shell, the first shell is rect...

Problems solved by technology

[0003] There are also some technical solutions for wristband-type mobile electrocardiographs in the prior art, such as a Chinese patent with application number CN202010791829.3, which includes a portable electrocardiograph body and a fixing device fixed at the lower end of the portable electrocardiograph body , the fixing device includes a first shell, the first shell is rectangular, the inside of the first shell is provided with a cavity, and the two ends of the cavity are respectively connected with first rollers, and the first The two ends of the roller are respectively connected to the side wall of the cavity by rotation, but when wearing a wristband type mobile electrocardiograph, when the wristband is used for different wearers, the size of the wristband needs to be adjusted according to different people because of different people wearing it. Wrist design, at the same time, when wearing, the excess wrist strap is exposed to the outside world after the wrist size is fixed, and the wrist strap is in contact with other objects, which makes the wrist-type mobile electrocardiograph easy to fall off; The movement of the wristband-type mobile electrocardiograph affects the stability of the wearer. The contact area between the electrocardiograph and the wrist is small, so that the electrocardiograph measures the biological signal generated by the cardiac myocardium and affects the display of the electrocardiogram. The wristband moves when worn in hot summer. The contact surface between the electrocardiograph and the wrist is prone to sweat and produces odor, and the skin on the wrist will turn white and be damaged under the soaking of sweat
