Description

Technical Field

[0001] The utility model relates to an improved electrocardiogram lead device. Background Art

[0002] Electrocardiographs are often used to detect the physiological functions of the human heart. They measure the potential differences of various parts of the human body through chest leads and limb leads. The resulting ECG waveform reflects the condition of the human heart.

[0003] The ECG lead wires currently in use include multi-core shielded cables, splitters and branch lead wires. The branch lead wires include 2 upper limb lead wires, 6 chest lead wires and 2 lower limb lead wires. The multi-core shielded cable is directly divided into branch lead wires after passing through the splitter. The ends of the chest lead wires are respectively connected to ball-type electrodes, and the ends of the upper limb lead wires and the lower limb lead wires are respectively connected to electrode clips.

[0004] In clinical work, the lead wires of the electrocardiogram machine are long, numerous, and easy to tangle. It takes time and effort to separate them. The lead wires need to be sorted out every time an electrocardiogram is taken, which is a cumbersome procedure and time-consuming operation. The electrode and negative pressure suction ball of the suction ball type electrode have a large blind area, which is a blind area for infection control and disinfection in the hospital. The electrocardiogram is one of the routine examination items, and the number of patients seen every day is large, so it is difficult to disinfect each patient. Therefore, it is necessary to design an improved electrocardiogram lead device to improve the above defects. Utility Model Content

[0007] Preferably, the shell includes an upper transverse portion, an oblique fold portion and a lower transverse portion connected in sequence, the angles between the oblique fold portion and the upper transverse portion and the lower transverse portion are all obtuse angles, and the top surfaces and bottom surfaces of the oblique fold portion, the upper transverse portion and the lower transverse portion are respectively arranged with the electrode contact ends.

[0010] Preferably, the insulating isolation pad is a silicone pad.

[0011] Preferably, each electrode contact end on the top surface of the shell is connected to each electrode contact end on the bottom surface of the shell in a one-to-one correspondence to form a columnar electrode.

[0016] Compared with the prior art, the improved electrocardiogram lead device of the utility model has the following beneficial effects:

[0017] (1) The chest lead adopts a shell. The shell is made of silicone with a certain weight and can fit the chest. The shell has two functions: one is to store the wire parallel electrode, and the other is to close the internal structure and not contact the patient's skin (except for the electrode contact end surface). Six electrode contact ends are set on the top and bottom surfaces of the shell. The electrode contact ends on the top and bottom surfaces of the shell correspond to each other. Every two corresponding electrode contact ends are connected to a lead wire. These lead wires extend out of the shell and are wrapped by an insulating rubber hose, which effectively solves the problem of easy entanglement, time-consuming and laborious separation, and the need to organize the lead wires every time an electrocardiogram is performed. The procedure is cumbersome and time-consuming. The electrode contact ends protruding from the top and bottom surfaces of the shell are used instead of the suction ball electrodes, which makes disinfection more convenient and can also be done for one person, effectively solving the problem of blind spots in infection control and disinfection in hospitals.

[0018] (2) The shell comprises an upper transverse portion, an oblique fold portion and a lower transverse portion. The angles between the oblique fold portion and the upper transverse portion and the lower transverse portion are all obtuse angles, forming a Z-shaped structure, which is very convenient for chest lead detection. In addition, the six electrode contact ends protruding from the bottom surface of the shell and distributed in the Z-shaped structure can be used for left chest detection, and the six electrode contact ends protruding from the top surface of the shell and distributed in the Z-shaped structure can be used for right chest detection.

[0019] (3) An insulating isolation pad is used on the skin surface to separate the electrode contact ends on the upper transverse part and the oblique fold part facing the skin, so that the chest lead can perform posterior chest detection without the need to use other lead structures for posterior chest detection, which can improve operating efficiency and save material costs.

[0020] (4) The insulating isolation pad is made of silicone pad, and the shell and flat shell are made of silicone material, which can improve comfort when in contact with the skin and is easy to disinfect.

[0021] (5) Both upper limb leads and lower limb leads use a flat shell and cylindrical electrodes, replacing traditional electrode clips. They are easy to disinfect and can be disinfected for each person.

[0022] (6) The lead wires connecting the six pairs of electrode contact ends are wrapped in an insulating rubber tube and a docking terminal 1 is designed at the end of the insulating rubber tube. The branch lead wires connecting the electrodes of the limbs are wrapped in a Y-shaped rubber tube and a docking terminal 2 is designed at the end of the Y-shaped rubber tube. A connecting line with two pairs of sockets is used to connect the docking terminal 1 and the docking terminal 2, thereby effectively solving the problem of easy entanglement and time-consuming and labor-intensive separation.

[0032] The upper limb leads and lower limb leads respectively include two branch lead wires 1 and electrodes 2 connected to the ends of the branch lead wires 1. Each electrode 2 is a cylindrical electrode. One axial end of the cylindrical electrode is mounted on a flat shell 3. The other axial end of the cylindrical electrode protrudes from the surface of the flat shell 3. The lead wire 1 is electrically connected to the cylindrical electrode and extends through the side of the flat shell 3. The flat shell 3 is made of silicone. The two branch lead wires 1 of the upper limb leads and the two branch lead wires 1 of the lower limb leads are wrapped by a Y-shaped rubber tube 11 and a docking end 2 12 is provided at the end of the Y-shaped rubber tube 11. The four branch lead wires 1 are all provided at the docking end 2 12.

[0033] The chest lead includes a shell 4, and the shell 4 is made of a silicone material with a certain weight. The silicone material is soft and can fit the chest. Six electrode contact terminals 5 are protruded from the top and bottom surfaces of the shell 4 respectively. The electrode contact terminals 5 on the top and bottom surfaces of the shell 4 correspond to each other one by one. Every two corresponding electrode contact terminals 5 form a pair and are connected to a lead wire 6 together. There are six lead wires 6 in total for the six pairs of electrode contact terminals 5. The six lead wires 6 extend out of the shell and are wrapped by an insulating rubber hose 8. A docking terminal 81 is set at the end of the insulating rubber hose 8. The six lead wires 6 are all set at this docking terminal 81. In addition, each electrode contact terminal 5 on the top surface of the shell 4 corresponds to each electrode contact terminal 5 on the bottom surface of the shell 4 and is connected to form a cylindrical electrode. The six electrode contact terminals 5 on the top surface of the shell 4 correspond to the six positions where the left chest needs to be led, and the six electrode contact terminals 5 on the bottom surface of the shell 4 correspond to the six positions where the right chest needs to be led.

[0034] The housing 4 includes an upper transverse portion 41, an oblique fold portion 42 and a lower transverse portion 43 connected in sequence in both the top view and the front view. The angles between the oblique fold portion 42 and the upper transverse portion 41 and the lower transverse portion 43 are all obtuse angles. The oblique fold portion 42, the upper transverse portion 41 and the lower transverse portion 43 form a Z-shaped structure. The top and bottom surfaces of the oblique fold portion 42, the upper transverse portion 41 and the lower transverse portion 43 are respectively provided with the electrode contact terminals 5. The insulating rubber tube 8 is located at the end of the upper transverse portion 41 away from the oblique fold portion 42, and can pull the housing 4 to prevent the housing 4 from shifting when placed on the patient's chest.

[0035] The top and bottom surfaces of the oblique folding portion 42 are each distributed with one electrode contact terminal 5, the top and bottom surfaces of the upper transverse portion 41 are each distributed with two electrode contact terminals 5, and the top and bottom surfaces of the lower transverse portion 43 are each distributed with three electrode contact terminals 5, so that the six electrode contact terminals 5 on the top surface of the housing 4 and the six electrode contact terminals 5 on the bottom surface of the housing 4 each form a Z-shaped structure. The three electrode contact terminals 5 on the top or bottom surface of the lower transverse portion 43 correspond to the three positions of the posterior chest leads.

[0036] The insulating spacer 7 is a silicone pad and can be placed on the skin surface to separate the electrode contact ends 5 on the upper transverse portion 41 and the oblique fold portion 42 that face the skin.

[0037] One end of the connecting line 9 is a connecting port 91, and the other end of the connecting line 9 has two sockets 92 that are respectively plugged into the docking terminal 1 81 and the docking terminal 2 12.

[0038] During the inspection, the six electrode contact ends 5 on the top surface of the housing 4 and the six electrode contact ends 5 on the bottom surface can be used to contact the skin of the right chest and the left chest respectively to perform the right chest and the left chest detection respectively (when performing the left chest and the right chest detection, the housing 4 can be turned over). The housing 4 can use its own weight to make the six electrode contact ends 5 on the protruding surface stick to the patient's skin surface. The upper limb leads and the lower limb leads are placed in order on the patient's limbs contacting the bed surface, and the electrode surface of the electrode 2 protruding from the surface of the flat housing 3 is allowed to contact the patient's skin. For the detection of the back chest, an insulating isolation pad 7 can be used to pad the skin surface to separate the electrode contact ends 5 on the upper transverse part 41 and the oblique fold part 42 facing the skin side, so that the electrode contact ends 5 facing the skin side do not contact the patient's skin, and the three electrode contact ends 5 on the lower transverse part 43 are in contact with the skin for lead detection.

[0039] Each patient has a different body shape and chest size, so the shell 4, electrode contact end 5, flat shell 3 and electrode 2 are designed to be large, medium and small in size to cope with the above.

[0040] In other embodiments, Figure 5As shown, each electrode contact end 5 on the top surface of the shell 4 and each electrode contact end 5 on the bottom surface of the shell 4 are respectively independent cylindrical electrodes, the electrode contact end 5 is located at the lower part of the cylindrical electrode on the top surface of the shell 4 and is fixed in the shell 4, and the electrode contact end 5 is located at the upper part of the cylindrical electrode on the bottom surface of the shell 4 and is fixed in the shell 4, and every two corresponding electrode contact ends 5 are connected by a wire and the wire is connected to the lead wire 6.
