Description

A disposable electrocardiogram electrode needle

technical field

The utility model belongs to the technical field of medical equipment, in particular to a disposable electrocardiogram electrode needle.

Background technique

The electrocardiogram instrument is an important device for detecting heart function. The electrodes are fixed on the human skin and connected to the electrocardiogram instrument to draw an electrocardiogram. Its physical principle is to transmit the ECG vector generated during the depolarization and repolarization process of the heart to all parts of the body through volume conduction, and generate a potential difference, which is displayed on the ECG machine to draw an ECG. The wires that place the electrodes and connect to the ECG machine are called ECG leads. Electrocardiogram leads include chest leads and limb leads, and existing electrocardiogram chest lead electrodes generally include suction cup electrodes, air bags and chest lead wire connectors. The suction cup electrode is generally made of metal material, the lower end of the suction cup electrode is the suction port, and the upper part is the connection port; the air bag is generally made of rubber, and is tightly installed on the suction cup electrode interface; the ECG chest lead wire connector is set on the suction cup electrode. When in use, first connect the electrocardiogram chest lead wire connector to the electrocardiogram chest lead wire, then smear conductive liquid on the chest skin of the subject, then press the airbag, and absorb the suction cup electrodes on the skin of the subject, so that, An electrocardiogram can be performed.

At present, there are many disadvantages in the suction cup electrode of the chest lead of the electrocardiogram: First, when the same patient measures the ECG for many times, the suction cup electrode needs to be reinstalled each time, which will cause the same patient to measure the electrocardiogram multiple times, and the position of the electrode placement is different each time. fixed. Moreover, due to the large contact area between the suction cup electrode and the skin, the positioning is not accurate. These two points lead to incomparability between ECG results, and it is impossible to accurately judge the condition changes of critically ill patients such as acute myocardial infarction, which delays the condition. In addition, there is a large space in the suction cup electrode, so the contact between the skin and the electrode pad is not firm and easy to fall off under the negative pressure of the airbag, which will affect the quality of the ECG. Finally, the smearing process of conductive liquid is cumbersome, and the amount is difficult to master. If the amount is too small, the conductive performance will be weakened and affect the ECG signal; if the amount is too large, the conductive liquid will flow around on the skin, which is a waste of resources and is unhygienic. It is easy to cause cross-infection .

Utility model content

The utility model mainly provides a disposable electrocardiogram electrode needle for the current electrocardiogram chest lead suction cup electrodes that have problems such as unfixed measurement positions, inaccurate positioning, poor contact between electrode sheets and skin, cumbersome operation process and the like.

Utility model content

detailed description

Example 1

As shown in Figures 1 and 2, a disposable electrocardiogram electrode needle is composed of a patch 1, a lead electrode 2, an electrode needle 3 and a chest lead electrode line 4, and the lead electrode 2 is arranged on the patch 1. The electrode needle 3 of the lead electrode 2 is arranged on one side of the inner surface of the patch 1 and extends to the outside of the patch 1. An adhesive layer 5 and an anti-adhesive interlayer covering layer 6 are arranged in sequence from the inside to the outside, and an insulating layer 7 is arranged on the base of the electrode needle 3 .

Specific steps of use: 1. Find the place where the human chest lead electrode is placed, implant the electrode needle of the lead electrode under the skin, tear off the anti-adhesive compartment covering layer 6, paste the patch on the skin, and fix the lead electrode . 2. Connect the lead electrode and the chest lead wire, and then start the ECG measurement. 3. After the measurement is completed, the chest lead wire is removed, and the disposable ECG electrode needle is left on the patient's skin. The next time you need to measure again, just connect the lead wire directly to the lead electrode.
