However, when used by some patients with high skin sensitivity, the bonding method is easy to cause discomfort to the patient's skin. At the same time, when the patient with the electrode patch wipes his body with water, it is not convenient to protect the connection between the electrode patch and the wire from moisture, which causes water to enter the joint connection between the wire and the electrode patch, which is easy to affect the normal use of the electrode patch.
[0005] Therefore, we propose a moisture-proof ECG electrode to solve the above-mentioned problems. Utility Model Content

At the same time, when the patient with the electrode patch attached wipes his body with water, it is not convenient to protect the connection between the electrode patch and the wire from moisture, which leads to the problem that when the water source enters the joint connection between the wire and the electrode patch, it is easy to affect the normal use of the electrode patch.
[0007] To achieve the above object, the utility model provides the following technical solutions: a moisture-proof ECG electrode, comprising an electrode body, a connecting terminal is installed in the middle of the upper end of the electrode body, and an external wire is connected to the connecting terminal;
[0008] Also includes:

[0010] A positioning column is fixed to the middle of the upper end of the soft cushion, the left and right sides of the positioning column are fixedly connected with connecting blocks, and a fixing column is fixedly connected between the connecting block and the soft cushion, a piston rod is inserted into the interior of the fixing column, and a rubber pad is fixedly connected to the side of the lower end of the piston rod;
[0011] A clamping column is fixed on the right side of the upper end of the positioning column. A transmission screw is connected to the middle of the clamping column, and a pressure block is connected to the lower end of the transmission screw. An active airbag is installed between the pressure block and the clamping column, and the active airbags are connected to each other through a connecting tube and a sealing bag. The sealing bag is located in the middle of the positioning column.
[0012] Preferably, the lower end of the fixing column is configured as an open structure, and the lower end opening of the fixing column and the adsorption hole on the soft pad are located on the same vertical line.
[0013] By adopting the above technical solution, the fit between the soft pad and the human skin can be ensured.
[0014] Preferably, the outer wall of the rubber pad bonded to the side of the lower end of the piston rod fits with the inner wall of the fixed column, and the piston rod and the fixed column are slidably connected.
[0015] By adopting the above technical solution, the sealing performance of the piston rod when it moves inside the fixed column can be ensured by setting the rubber pad.
[0016] Preferably, the transmission screw and the middle part of the clamping column are threadedly connected, and the transmission screw and the pressing block at the lower end are vertically distributed.
[0017] By adopting the above technical solution, when the transmission screw is rotated on the clamping column, the pressing block at its lower end can move synchronously.
[0018] Preferably, the pressing block and the active airbag are in contact with each other in an initial state, and the pressing block and the active airbag are located on the same vertical line.

[0022] Compared with the prior art, the utility model has the following beneficial effects: the moisture-proof ECG electrode can avoid the need to use an adhesive method to fix the electrode sheet to the human skin when in use, and can also provide moisture-proof protection for the connection between the wire and the electrode sheet;
[0023] 1. A soft pad is provided, and the soft pad can increase the fit with human skin. At the same time, the piston rod is pulled upward to the fixed column to move inside the fixed column. At this time, the negative pressure generated by the movement of the piston rod is used to make the soft pad closely fit and adsorb on the surface of human skin, thereby avoiding the use of bonding to make the electrode body fixedly contact with human skin;
[0024] 2. A sealing bag is provided. When the transmission screw is rotated, the pressure block at the lower end can move toward the lower end of the clamping column. The active airbag can be squeezed by the movement of the pressure block. When the active airbag is pressurized, the airflow inside it enters the interior of the sealing bag through the connecting pipe. The expansion of the sealing bag after inflation makes it close to the external wire, thereby filling the gap between the positioning column and the external wire, preventing water from coming into contact with the joint of the connecting end and the external wire through the gap when wiping the body.

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1-Figure 5 The utility model provides a technical solution: a moisture-proof ECG electrode, comprising an electrode body 1, a connecting terminal 4 is installed in the middle of the upper end of the electrode body 1, and an external wire 5 is connected to the connecting terminal 4; a soft pad 2 is installed on the side of the electrode body 1, and adsorption holes 3 are opened on the left and right sides of the soft pad 2; a positioning column 6 is fixed in the middle of the upper end of the soft pad 2, and a connecting block 7 is fixedly connected to the left and right sides of the positioning column 6, and a fixing column 8 is fixedly connected between the connecting block 7 and the soft pad 2, a piston rod 9 is inserted into the inside of the fixing column 8, and a rubber pad 10 is fixedly connected to the lower end side of the piston rod 9; the lower end of the fixing column 8 is set to an open structure, and the lower end opening of the fixing column 8 and the adsorption hole 3 on the soft pad 2 are located on the same vertical straight line. The outer wall of the rubber pad 10 bonded to the lower end side of the piston rod 9 fits with the inner wall of the fixing column 8, and the piston rod 9 and the fixing column 8 are slidably connected.
[0033] like Figure 1 and Figure 3 As shown, the electrode body 1 is placed on the corresponding skin of the patient. The setting of the soft pad 2 can increase the fit between the electrode body 1 and the external skin. Then, the piston rod 9 is pulled upwardly to the top of the fixed column 8 to move the piston rod 9 upwardly to the fixed column 8. After the piston rod 9 moves, negative pressure can be generated inside the fixed column 8, so that the soft pad 2 can be stably adsorbed on the patient's skin. When the electrode body 1 is used, it is avoided that the electrode body 1 contacts the human skin by bonding, thereby reducing the possibility of discomfort to the patient's skin caused by bonding.
[0034] The clamping column 11 is fixed on the right side of the upper end of the positioning column 6. The middle part of the clamping column 11 is connected with a transmission screw 12, and the lower end of the transmission screw 12 is connected with a pressure block 13. An active airbag 14 is installed between the pressure block 13 and the clamping column 11, and the active airbag 14 is connected to each other through a connecting pipe 15 and a sealing bag 16. The sealing bag 16 is located in the middle part of the positioning column 6. The transmission screw 12 and the middle part of the clamping column 11 are threadedly connected, and the transmission screw 12 and the pressure block 13 at the lower end are vertically distributed. The pressure block 13 and the active airbag 14 fit each other in the initial state, and the pressure block 13 and the active airbag 14 are located on the same vertical straight line. The airflow inside the active airbag 14 can enter the interior of the sealing bag 16 through the connecting pipe 15, and the sealing bag 16 is set as an annular structure, and a hole is opened in the middle of the sealing bag 16 for the external wire 5 to pass through.
[0035] like Figure 1 , Figure 4 and Figure 5 As shown, when it is necessary to wipe the patient's skin, the transmission screw 12 is rotated so that the transmission screw 12 drives the pressure block 13 at its lower end to move toward the lower end of the clamping column 11. After the pressure block 13 moves, it can squeeze the active airbag 14, so that the airflow inside the active airbag 14 enters into the interior of the sealing bag 16 through the connecting tube 15. The sealing bag 16 is inflated to block and seal the connection gap between the external wire 5 and the positioning column 6, so as to prevent water from entering into the interior of the positioning column 6 through the gap when wiping the body, causing the connection between the connecting terminal 4 and the external wire 5 to become damp.
[0036] Working principle: When using this moisture-proof ECG electrode, first Figure 1-Figure 5 As shown, the setting of the soft pad 2 can increase the fit between the soft pad 2 and the external skin, and then the piston rod 9 is pulled toward the top of the fixing column 8. After the piston rod 9 moves, negative pressure can be generated inside the fixing column 8, so that the soft pad 2 can be stably adsorbed on the patient's skin, so that when the electrode body 1 is used, the electrode body 1 is prevented from contacting the human skin by bonding. The transmission screw 12 drives the pressure block 13 at its lower end to move toward the lower end of the clamping column 11, and squeezes the active airbag 14 so that the air flow inside it enters into the sealing bag 16 through the connecting tube 15. The sealing bag 16 is inflated to block and seal the connection gap between the external wire 5 and the positioning column 6, so as to prevent water from entering into the positioning column 6 through the gap when wiping the body, causing the connection between the connecting terminal 4 and the external wire 5 to become damp.
