Description
Technical Field
The utility model relates to an electrocardiogram equipment especially relates to a dual-purpose electrocardio lead line is stinged to a line formula knot, belongs to medical instrument technical field.
Background
The ECG cable is an external connection transmission carrier for connecting a patient with a monitor or an electrocardiograph. The electrocardiogram is recorded by connecting the electrocardiogram electrodes arranged at different parts of the human body and connecting the electrodes with the anode and the cathode of a monitor or an electrocardiogram machine. This method of connecting the circuits for recording an electrocardiogram is called electrocardiogram lead. The international universal lead system widely adopted at present is called a conventional 12 lead system. Including limb leads connected to the limbs and chest leads connected to the chest.
At present, the prior art generally adopts a main line-relay box-branching structure, and the connection mode of the main line-relay box-branching structure and the electrode plate connecting end is only one of the following modes: snap-on, clip-on, or pin-on (requiring further connection of a snap-on adaptor or ball-on electrode).
It has the following disadvantages: first, the procedure requires the operator to prepare for the correct connection of the corresponding electrode sites on a lead-by-lead basis, according to ANSI/AAMI EC53:1995, electrocardioelectrode placement site and label, as established by the general American Heart society. But actually, the patient needs to compete for the second in some scenes such as chest pain centers, emergency rooms, ambulances and the like; or some acute cardiac disorders: for example, when acute myocardial infarction needs to be diagnosed by a horse with an accurate focus, the conventional electrocardio-lead wire has too long operation time and cannot be quickly connected with a patient and electrocardio-diagnosis equipment in a short time, so that abnormal electrocardiograms and abnormal ST wave bands cannot be quickly, effectively and timely detected. In addition, in the operation process, wrong electrocardiogram signals caused by misplacement of lead branching lines are easy to appear, and the correct judgment of the illness state by a doctor is influenced.
Second, due to the branching structure, as shown in fig. 5, a large number of electric wires are distributed on the human body. When surgery or other treatment is required on the patient, it is very disturbing and the patient itself is very uncomfortable.
Thirdly, the connection mode of the current electrocardiograph lead wire in the prior art and the electrode plate connecting end is only one of the following modes: snap-on, clip-on, or pin-on (requiring further connection of a snap-on adaptor or ball-on electrode). In a hospital use scene, two disposable electrocardio electrodes attached to a patient are generally used. The electrode close to the limb part mostly adopts a button electrode plate with a larger area, the electrode around the chest part of the heart part mostly adopts a sheet electrode plate with a smaller area (because the centrifugal dirty part of the limb lead is far away, the electrocardiosignal is conducted by the contact with a larger area, the chest lead is very close to the heart, and the signal is easy to collect, so the electrode with a large area is not needed. And wherein knot formula and formula of clamp belong to and need the mode of a little press to connect the electrode piece, to suffering from skin damage: for example, burn and scald patients are easy to cause certain injuries, which leads to pain of patients.
Fourthly, the electrocardiograph lead wire needs to be cleaned before being used, so that bacterial infection is prevented. At present, the electrocardio lead wire adopting the branching structure consumes long time for cleaning, and the branching structure is easy to store dirt and dirty, so that the phenomenon of incomplete cleaning exists, and bacteria are caused to infect patients.
