ECG monitors can simultaneously collect, store and intelligently analyze patients' ECG information, providing doctors with timely and accurate diagnosis basis, thereby effectively reducing complications and promoting patient recovery. However, due to the large number of various wires equipped with ECG monitors, it is inconvenient to store, resulting in messy placement. When the ECG monitor is moved to the bedside, multiple lead wires are often exposed and easily entangled with each other, which not only increases the difficulty of operation during nursing by nurses, but may also cause electrodes to fall off or equipment to fall and be damaged, causing unnecessary losses and safety hazards; and it often takes time to organize the lead wires before the examination, affecting the examination time; in addition, ECG monitors need to replace the electrode sheet and sterilize the lead wires after each use, but the existing disinfection method is mostly to send them to the disinfection cabinet manually for processing, which is complicated and affects the equipment turnover efficiency, and is not conducive to quickly responding to the monitoring needs of multiple patients.

[0003] At present, most medical carts are used as ECG monitoring carts, that is, ECG monitors are placed on medical carts to improve their mobility. However, existing medical carts cannot effectively fix and organize the lead wires of ECG monitors, resulting in cluttered lead wires, affecting usage efficiency and patient comfort.

[0015] Furthermore, the cart base is provided with a groove cooperating with the lower end of the infusion pole, the groove is arranged directly below the clamping card, and the groove and the clamping card are both arranged on one side of the cart handle.

[0016] The principle and beneficial effects of the technical solution are:

[0017] 1. The multifunctional ECG monitoring cart provided by the present invention places the ECG monitor on the cart body, and the universal wheel set and the cart handle connected to the cart body facilitate its transportation and convenient operation; the reeling assembly and the disinfection assembly are connected to the cart body, and the reeling assembly reels and unwinds the lead wires of the ECG monitor to prevent multiple lead wires from being scattered and entangled with each other; the disinfection assembly disinfects the lead wires before and / or after use, simplifies the disinfection process, and improves the disinfection efficiency, thereby ensuring the use effect and efficiency of the ECG monitor;

[0018] The winding assembly includes a winding box, a planetary gear train (a driving sun gear, a fixed gear ring and a pair of driven planetary gears), a winding handle and a transmission main shaft, and the driven planetary gear is coaxially fixedly connected to the winding shaft, and the pair of winding shafts are mirror-symmetrically arranged with a plane passing through the central axis of the transmission main shaft as a reference plane. When the winding assembly is used to wind up the lead wire, part of the lead wire is first fixed on the transmission main shaft, and when the winding handle is rotated, the winding handle drives the driving sun gear to rotate, and because the driven planetary gear is externally meshed with the driving sun gear, and the driven planetary gear is internally meshed with the fixed gear ring, and the fixed gear ring is fixedly connected to the winding box, the pair of driven planetary gears rotate while rotating around the center of rotation of the driving sun gear under the action of the fixed gear ring and the driving sun gear, and the pair of winding shafts are fixedly connected to the pair of driven planetary gears, which, like the driven planetary gears, rotate while rotating around the center of rotation of the driving sun gear, so that the lead wire can be effectively wound around the pair of winding shafts evenly and firmly;

[0019] The disinfection assembly includes a liquid storage tank and a disinfection handle. The disinfection handle is rotatably connected to the liquid outlet drum, and the liquid outlet drum is connected to the liquid storage tank. When unwinding or rewinding the lead wire, the disinfectant flows out of the liquid outlet drum to wipe and disinfect the surface of the lead wire. The used disinfectant is collected in the waste liquid tank.

[0020] 2. The multifunctional ECG monitoring cart provided by the present invention has a uniform component connected to the transmission main shaft, which can effectively ensure the uniformity of the rotation of the reeling handle, so that the lead wire can be evenly and stably reeled on a pair of reeling shafts, and the uniform component can also prevent medical staff from excessively or accidentally pulling and / or pulling the lead wire, resulting in accidental damage to the lead wire and / or the ECG monitor;

[0021] The principle of the uniform assembly is as follows: the fixed ratchet is fixedly connected to the inner side wall of the winding box, the linkage disc is coaxially fixedly connected to the winding handle and the active sun gear, and when the winding handle is rotated, the linkage disc rotates accordingly. When the winding handle rotates evenly and smoothly, the tension spring and the pawl rotate with the rotation of the linkage disc. When the winding handle rotates unevenly (suddenly accelerates or suddenly decelerates), the pawl is subjected to the centrifugal force to overcome the force of the tension spring and rotates relatively, so that the pawl meshes with the ratchet teeth of the fixed ratchet wheel, restricting the rotation of the pawl, thereby restricting the rotation of the winding handle;

[0022] 3. The multifunctional ECG monitoring cart provided by the present invention has a liquid storage tank connected to a liquid drawing component, and the piston component of the liquid drawing component is connected to the disinfection handle, and the piston component is also connected to the liquid guide cylinder through a spring, so that when the disinfection handle is pressed downward to drive the liquid outlet roller close to the lead wire, the disinfectant in the liquid storage tank flows out from the liquid outlet of the liquid outlet roller under the action of atmospheric pressure to disinfect the lead wire, and when the force on the disinfection handle is canceled, it is reset under the action of the spring and waits for the next pressing to discharge liquid and disinfect; that is, the liquid drawing component is a liquid "pressing device", which can be pressed downward to take liquid, and the liquid outlet of the liquid storage tank is closed when the pressing is canceled. In this technical solution, the liquid outlet of the liquid outlet roller discharges liquid when it is close to the lead wire and is closed when it is far away from the lead wire, thereby improving the disinfection effect on the lead wire and reducing the waste of disinfectant;

[0023] 4. The multifunctional ECG monitoring cart provided by the present invention has a guide shaft arranged between the reeling assembly and the disinfection assembly, and the guide shaft guides and limits the movement of the lead wire, so that the lead wire can be evenly, smoothly and neatly reeled and / or disinfected; and an anti-slip sleeve is wrapped around the outer side of the transmission main shaft, the reeling shaft and the guide shaft to increase the friction between the lead wire and the shaft surface, thereby ensuring the functionality of each shaft;

[0024] 5. The multifunctional ECG monitoring cart provided by the present invention has a waste liquid tank, a storage drawer, a trash bin, a suction pump, an injection pump, a battery and a clamping card connected to the cart base, and the battery is connected to a socket through an electrical wire, so that the cart has multiple functions such as throwing away garbage, storing, suctioning sputum, injection, taking electricity, and hanging infusion bottles, thereby improving the application scope and convenience of the entire device; and the waste liquid tank is arranged directly below the liquid outlet of the waste liquid tank body, and the trash bin is arranged below the waste liquid tank, which is convenient for collecting and processing waste liquid; the battery and the socket are arranged on the side away from the waste liquid tank to avoid the battery and the socket from contacting liquid, thereby ensuring the safety of electricity use;

[0025] 6. The multifunctional ECG monitoring cart provided by the present invention has two storage spaces arranged in the storage drawer, and the two storage spaces are respectively connected to the step assembly and the clamping members arranged in pairs, so as to facilitate the placement of different items in different areas and categories, avoid the disorder of various medical instruments, and avoid damage caused by accidental sliding and collision between instruments; wherein, the clamping members fix and clamp bottle-shaped instruments, etc., so that they are not easy to fall over, and the stability is improved; the clamping clamp is connected to the outer side wall of the cart base, and a groove is arranged on the lower side thereof, so that the lower end of the infusion pole is clamped in the groove, and the middle part is clamped between the clamping clamps, which can effectively ensure the stability of the infusion pole and facilitate the disassembly and assembly of the infusion pole.
