[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] See also Figure 1 - Fig. 9 , an electrocardiograph with an anti-drop electrode sheet, comprising an electrocardiograph 1, an electrode sheet 8, a conductive clip 9 and a winding frame 3, characterized in that a winding frame 3 for winding a first lead wire 2 is fixedly installed on one side of the electrocardiograph 1 through a bracket, and first connectors 4 are respectively provided at both ends of the first lead wire 2, the first connector 4 at one end is docked with an interface 5 of the electrocardiograph 1, and the first connector 4 at the other end is electrically connected to a second lead wire 7 by plugging a second connector 6, and an electrode sheet 8 or a conductive clip 9 is fixed at the other end of the second lead wire 7;

[0034] The electrode chip 11 in contact with the patient's skin is provided at the lower end of the electrode sheet 8, and a disposable positioning auxiliary block 12 is installed at the lower end of the electrode sheet 8 to prevent the electrode sheet 8 from falling off. A medical adhesive layer 13 for bonding the patient's skin is provided at the bottom of the disposable positioning auxiliary block 12, and a clearance groove 14 for the electrode chip 11 to pass through is provided in the middle of the disposable positioning auxiliary block 12 and the medical adhesive layer 13;

[0035] A preheating seat 15 for preheating the electrode sheet 8 and the electrode chip 11 is fixed to the upper end of the winding frame 3, and a disinfection seat 17 for wiping and disinfecting the electrode sheet 8 and the electrode chip 11 is clamped at the lower end of the winding frame 3 through an L-shaped block 16. Considering that the existing motor sheet is fixed with a chest suction ball, when the suction ball is not firmly attached to the skin due to factors such as body position, weight loss, loose skin, illness, and sagging breasts of the patient, and becomes loose or falls off, after the suction ball electrode falls off, there will be position deviation when it is put on again, which will affect the electrocardiogram waveform result, and the unstable waveform will affect the diagnosis result, while prolonging the patient's treatment time, which is not conducive to patient safety and has the problem of potential disputes. The present invention provides a disposable positioning auxiliary block 12 to quickly fix the electrode sheet 8, and uses the medical adhesive layer 13 at the bottom of the disposable positioning auxiliary block 12 to bond with the patient's skin, and then uses the electric The electrode sheet 8 can be fixed by inserting the embedding block 23 of the resistance piece 18 at the outer edge of the lower end of the electrode sheet 8 into the embedding groove 22. When the electrode sheet 8 falls off, the disposable positioning auxiliary block 12 is bonded and fixed to the patient's skin, that is, the position will not be offset. The electrode sheet 8 can then be reinstalled, and the resistance piece 25 is pressed to compress the reset spring 24 of the resistance piece 18, and then the electrode chip 11 is inserted into the yield groove 14. When the embedding block 23 of the resistance piece 18 is located inside the yield groove 14, the resistance piece 18 will be released. At this time, the reset spring 24 resets the embedding block 23 and will be inserted into the embedding groove 22 to complete the fixing process. Considering the hygiene issue, the disposable positioning auxiliary block 12 that contacts the patient over a large area can be discarded and replaced after use, and the electrode chip 11 that contacts the patient over a small area will be disinfected by wiping with a disinfectant sponge.

[0037] Please refer to Fig. 9 As shown, a return spring 24 is provided between the end of the abutment member 18 and the active cavity 19, and the end of the abutment member 18 passes through the side wall of the active cavity 19 and is fixed with a paddle 25. The embedded block 23 passes through the reserved groove at the bottom of the active cavity 19. Considering that the contact area between the abutment member 18 and the fingertips of the user is too small to be pressed easily, a paddle 25 is designed to increase the contact area with the fingertips, making it easier for the user to press the abutment member 18.

By setting the elastic clamping rod 27 to contact the docking ring 26, the first connector 4 and the second connector 6 for connecting the first lead wire 2 and the second lead wire 7 are not easy to fall off due to external force. When the first connector 4 and the second connector 6 are plugged in, the first connector 4 will clamp the docking ring 26 outside the second connector 6 through the elastic clamping rod 27, thereby completing the fixing process.

The small self-locking motor 31 is provided to drive the driving shaft 28 to rotate. When the driving shaft 28 is driven to rotate, the first lead wire 2 placed between the driven shaft 29 and the driving shaft 28 is transported, so that the first lead wire 2 is wound up, which prevents the first lead wire 2 from being too long after the connection with the second lead wire 7 and preventing the situation of entanglement.

[0040] Please refer to Figure 1 , Figure 2 and Figure 5As shown, a bending tube 34 and a horizontal tube 35 for threaded connection of the guide sleeve 33 are fixed on both sides of the winding frame 3, and the guide sleeve 33, the bending tube 34 and the horizontal tube 35 are evenly spaced on the surfaces of both sides of the winding frame 3. A plurality of guide wheels 36 for guiding the first lead wire 2 are rotatably connected inside each guide sleeve 33. In order to prevent the first lead wires 2 from being entangled with each other when they are wound up too long, the bent tube 34 and the horizontal tube 35 cooperate with the guide tube to guide the wound first lead wire 2, which effectively prevents the plurality of first lead wires 2 from being entangled with each other when they are wound up too long.

[0041] Please refer to Figure 1 , Figure 5 and Figure 6 As shown, a heat-conducting frame 37 is provided inside the preheating seat 15, an electric heating wire 38 is provided between the preheating seat 15 and the frame, and the heating wire is connected to the temperature controller 39 circuit, the temperature controller 39 is connected to the controller 32 circuit through a wire, an anti-slipping strip 40 is hinged at the upper end of the preheating seat 15, and metal blocks 42 adsorbed by magnetic blocks 41 are fixed on both sides of the end of the anti-slipping strip 40, and the magnetic block 41 is fixedly installed on the front end surface of the winding frame 3, and a temperature sensor is provided on the inner wall of the heat-conducting frame 37. By setting the preheating seat 15, the surface of the electrode chip 11 in contact with the patient's skin is heated, thereby improving the skin feel of the patient when using the device.

[0042] Please refer to Figure 2 and Figure 8 As shown, the lower end of the disinfection seat 17 is provided with an insertion groove for placing the disinfection sponge block 43, and the interior of the disinfection sponge block 43 is soaked with disinfectant, and the bottom of the disinfection seat 17 is hinged with a sealing cover 10. Considering that when the electrode chip 11 is in use, the disposable positioning auxiliary block 12 is a detachable and disposable disposable item, so there will be no hygienic problems. However, the electrode chip 11 in contact with the patient's skin needs to be disinfected, and it will be disinfected by wiping the surface of the disinfection sponge block 43. During the wiping process, the disinfectant soaked in the disinfection sponge block 43 will be coated on the surface of the electrode chip 11 by extrusion.
