Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a chest belt type 18-lead electrocardiogram lead system.
Background
The existing electrocardiograph is generally 12 leads, and the lead system thereof is composed of 6 chest leads and 4 limb leads. The traditional electrocardiograph has many disadvantages: (1) the lead wires are too many, and the lead wires are easy to wind and unclear during use, so that much inconvenience is brought to the operation. The winding of the circuit can increase the workload of medical staff, reduce the working efficiency and delay the rescue time in emergency. (2) The 6 anterior leading skin plug electrodes need to be placed one by one, the time consumption is long, confusion is easy, and the skin plug is not firmly adsorbed on the skin and is easy to fall off. (3) It is sometimes necessary to make 18-lead electrocardiogram clinically, especially for patients with acute myocardial infarction, 18-lead electrocardiogram should be made conventionally to determine whether to combine right ventricular infarction and posterior myocardial infarction at the same time. The 18 leads are 12 leads and 3 right chest leads and 3 back wall leads in the tradition, the tradition electrocardiograph must do the conventional 12 leads to make the 18 lead electrocardiogram, then move the V4, V5 and V6 electrodes to the positions of the right chest leads to finish the right chest lead electrocardiogram (V3R, V4R and V5R), and then let the patient right side lying position move the V4, V5 and V6 electrodes to the positions of the back wall leads to finish the back wall lead electrocardiogram (V7, V8 and V9). The process is complicated to operate, takes long time and is extremely unfavorable for rescuing acute myocardial infarction. The patients must be turned over and matched when the back wall leads are made, the skin plug is easy to fall off and the interference of the electrocardiogram is increased in the process, and partial patients with serious illness cannot be turned over and matched.
Some lead systems with improved designs have appeared so far, for example, CN 110464336a designs a self-adhesive chest strap lead, CN 209932731U designs a fixing device for chest lead, etc., but these designs do not realize 18 lead integration and the using method is not convenient enough, so they are not practically used in clinic at present.

The invention has the beneficial effects that: 18 leads an organic whole, convenient to use is not restricted by the position, extensive applicability, convenient electrocardiogram lead system of disinfecting. The method comprises the following specific steps:
(1)18, integration of the lead: the chest belt type lead of the invention comprises 12 electrodes, can simultaneously record 12 precordial lead electrocardiosignals of V1-V9+ V3R-V5R and the like, and has 18 channels in total by adding 6 channels of limb leads. Because the current electrocardiograph can only provide information of 12 channels, the invention divides the 12 channels of the chest leads into two groups, wherein, V1-V6 are one group; V3R-V5R and V7-V9 are another group, two interfaces are provided, when the chest strap is used for electrocardiographic examination of a patient, the interfaces are only replaced once to obtain the electrocardiograms of all 18 leads, and the position of the chest strap does not need to be reset.
(2) The use is convenient: the chest leads of 12 leads are integrated on the elastic chest belt, so that the number of the leads is greatly reduced, the chest belt is only bound and fixed on the chest of a patient when the chest belt is used, electrode skin plugs do not need to be adsorbed one by one, and the electrode positions do not need to be changed for recording 18-lead electrocardiogram for many times, so that the operation steps are greatly simplified, the examination time is saved, and the examination efficiency is improved. The invention also improves the upper limb lead system, changes the upper limb lead system into a hand ring type structure, only needs the two hands of the patient to hold the metal copper ring part, and is more convenient and faster to use compared with the original clamping type structure. For patients who have difficulty in holding, the wrist of the patient can be sleeved with the hand ring, and the applicability is wide.
(3) Is not limited by body position: the traditional electrocardiogram requires that a patient lies on the back and on the side (back chest leads) and cannot move, otherwise, a skin plug is easy to fall off, but the invention adopts a constrained chest belt structure and a hand-held upper limb lead system, so that the patient can complete electrocardiogram examination in any external body theoretically, and the structure has good fixing performance, so that the patient can move freely in the electrocardiogram process, and the lead system is also suitable for examination items such as a flat-plate exercise test, a dynamic electrocardiogram and the like.
(4) The applicability is wide: the elastic silica gel is used as the basal layer of the chest belt system, and the elastic fiber layer is used as the surface covering, so that the whole chest belt system has sufficient elasticity and can adapt to the change of the chest circumference of patients with different body types. Meanwhile, the lead wire connected with the metal dry electrode is a wavy flexible circuit, and the designs ensure that the whole system has good elastic deformation capacity and can adapt to the change of the chest circumference of the patient in a larger range. The support bar adopts the silica gel board that has certain hardness to make, when the chest area is tightly restrainted in patient's chest, can provide extra internal contraction power for the dry electrode of metal can contact with patient's skin well, avoids appearing the condition of electrode contact failure on the thin patient of some bodily forms is dry.
(5) The disinfection is convenient: according to the invention, the surface of the silica gel material is wrapped with the elastic leather cloth material, so that the defects that the silica gel material is easy to absorb stains and is not easy to clean and disinfect are avoided. The leather cloth has smooth surface and small surface friction with the skin, is not easy to adsorb stains, and is convenient to disinfect. Before use, the inner surface of the chest belt is wiped once by using alcohol cotton balls, so that the aim of disinfection can be achieved. In addition, the ultraviolet rays can be used for disinfection in idle time.
