DETAILED DESCRIPTION
[0020] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0021] Example: A suction cup for an electrocardiogram (ECG) instrument that can be adjusted according to individual body constitution, such as... Figures 1-3 As shown, the device includes a suction ball 1, a conductive sheet 2, a conductive suction cup 3, a hollow ring 6, and an adsorption plate 7. The outer wall of the suction ball 1 has protrusions for easy gripping by the user. By manually squeezing the suction ball 1, negative pressure can be quickly established or released in a short time, improving operational efficiency. The suction ball 1 is connected to the conductive suction cup 3. The conductive suction cup 3 has a hollow interior forming a channel that communicates with the inner cavity of the suction ball 1. The conductive suction cup 3 is made of metal, which ensures good conductivity between the electrode and the skin and reduces signal attenuation. The conductive sheet 2 is tightly attached to the outer wall of the conductive suction cup 3. The bottom of the conductive suction cup 3 is fitted with a hollow ring 6, and the bottom of the hollow ring 6 is connected to the adsorption plate 7. The adsorption plate 7 is used for contact with the skin. The hollow ring 6 and the adsorption plate 7 are made of conductive silicone rubber. Conductive silicone rubber is not only soft and elastic, but also adaptable to different body shapes and skin conditions, while ensuring stable conductivity.
[0022] like Figure 3 As shown, the top of the hollow ring 6 is evenly spaced with injection tubes 61 along its circumference, and the bottom of the hollow ring 6 has an injection through hole. This injection through hole is adapted to the fine holes opened on the adsorption plate 7. The injection tubes 61 are used to inject conductive paste or gel. The conductive paste or gel is injected into the hollow ring 6 through the injection tubes 61 and flows to the adsorption plate 7 through the injection through hole at the bottom of the hollow ring 6. Finally, it flows to the user's skin through the fine holes on the adsorption plate 7, thereby improving the adhesion and conductivity of the adsorption plate 7 and ensuring good contact even under complex skin conditions.
[0023] like Figure 2 and Figure 3 As shown, the outer wall of the hollow ring 6 is connected to the sealing ring 5 via the connecting block 51. The inner wall of the sealing ring 5 is in close contact with the outer wall of the hollow ring 6 and the adsorption plate 7, thereby preventing liquid leakage and external pollutants from entering the system, thus maintaining the cleanliness and service life of the equipment. In addition, it also ensures that the entire suction cup system has a good sealing effect and can work stably even in complex environments.
[0024] In use, the user squeezes and releases the suction ball 1, air is sucked out through the hollow channel of the conductive suction cup 3, a negative pressure is formed between the suction cup and the skin, the adsorption plate 7 is tightly attached to the skin surface, ensuring good contact of the electrode; when further enhancing the adsorption effect is needed (such as for thin and weak constitution), conductive paste or gel can be added through the liquid injection pipe 61, which will be evenly distributed on the adsorption plate 7 through the fine holes, increasing the adhesion and also improving the conductivity, thereby maintaining the stability of the conductive suction cup 3.
[0025] As shown in Figure 2 and Figure 4 , the conductive suction cup 3 is provided with a fixed tube 4 at the connection with the suction ball 1, the fixed tube 4 is vertically connected with a cylinder 8, the cylinder 8 penetrates through the fixed tube 4 and extends into the hollow channel of the conductive suction cup 3 and communicates with it, the piston rod 9 is slidably connected in the cylinder 8, the cylindrical end of the piston rod 9 is provided with a vent groove 12, when the vent groove 12 is located in the cylinder 8, the piston rod 9 seals the inner cavity of the cylinder 8, when the vent groove 12 communicates with the hollow channel of the conductive suction cup 3, the inner cavity of the cylinder 8 communicates with the hollow channel of the conductive suction cup 3, the user adjusts the negative pressure strength in the suction cup according to his own feeling by pushing the piston rod 9 along the cylinder 8.
[0026] As shown in Figure 4 , the end of the cylinder 8 away from the conductive suction cup 3 is installed with a limiting plate 10, the rod-shaped part of the piston rod 9 slides through the limiting plate 10, a spring 11 is arranged between the end of the piston rod 9 outside the cylinder 8 and the limiting plate 10, the spring 11 is arranged around the rod-shaped part of the piston rod 9, in normal state, the piston rod 9 cooperates with the inner wall of the cylinder 8 to seal the inner cavity of the cylinder 8, the spring 11 can be a rubber part with elastic property or a spring, the spring 11 in the embodiment is preferably a compression spring.
[0027] When the negative pressure in the conductive suction cup 3 is too large, the user will feel uncomfortable (such as the same negative pressure strength, obese people are more likely to feel uncomfortable due to the larger negative pressure strength), at this time, the piston rod 9 can be pushed towards the hollow channel of the conductive suction cup 3, when the piston rod 9 extends into the hollow channel of the conductive suction cup 3, the vent groove 12 communicates with the hollow channel of the conductive suction cup 3, thereby achieving the effect that the inner cavity of the cylinder 8 communicates with the hollow channel of the conductive suction cup 3, at this time, under the action of atmospheric pressure, the gas outside is input into the hollow channel of the conductive suction cup 3 through the cylinder 8 and the vent groove 12, thereby adjusting the negative pressure strength in the conductive suction cup 3, at the same time, it also provides convenience for removing the conductive suction cup 3 from the patient.
