The electrode fixing mode of the current ECG test instrument is mainly patch or suction disc for convenient positioning.

[0003] As shown in Figure 1 ECG test instrument electrode contains electrode connecting wire and 3.5 needle, manual suction rubber ball head, metal suction disc, fix the electrode metal suction disc on human skin, and connect with ECG test instrument, draw electrocardiogram. Due to the difference of patient age, body shape and skin, muscle, skin tension, chest surface uneven and other factors, metal suction disc is mainly used for conducting electricity and forming vacuum negative pressure chamber, but due to the difference of patient's specific situation, metal suction disc contact surface is small, easy to edge air leakage, not firm and easy to fall off, leading to part of patient's electrocardiogram distortion, prolonging the operation time, leading to misdiagnosis, missed diagnosis and other situations. Disposable electrode patch on the market is fixed on the patient's chest by adhesive tape, but part of the patient's skin is allergic to adhesive tape, which is discarded after use, wasting resources and increasing cost.

[0004] After testing, the resistance value of the existing single electrode metal suction disc is about 2Ω measured by multimeter, that is, the newly designed electrode can match the existing ECG test instrument if it meets the requirement of less than or equal to 2Ω. On this basis, the patentee designs a new type of ECG test instrument electrode suction disc assembly. SUMMARY

[0005] In view of the above shortcomings of the prior art, the utility model provides a kind of ECG test instrument electrode suction disc assembly, which is matched with the existing ECG test instrument, convenient and reusable, stable in use, and the suction volume is manually controllable, suitable for promotion.

[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows: a kind of ECG test instrument electrode suction disc assembly, including suction disc body, the suction disc body includes suction contact part that can be negatively adsorbed with patient's skin in the form of leather bowl, suction chamber communicated with the suction contact part, electrode connecting part with connecting jack and communicated with the suction chamber through the connecting jack, the connecting jack can be interference fit with electrode connecting wire and needle of ECG test instrument, wherein the suction contact part, suction chamber and electrode connecting part are integrally formed into the suction disc body by conductive silicone rubber.

[0007] Furthermore, the connection jack port on the electrode connection portion has a plug-in guide portion in the form of a bell mouth.

[0008] Furthermore, the adsorption chamber is a spherical structure with an air suction cavity at the center.

[0009] Furthermore, the adsorption contact portion and the electrode connection portion are located at both ends of the center line of the adsorption chamber.

[0010] Furthermore, the adsorption contact portion is connected to the adsorption chamber through a neck portion, and an air suction hole is set along the center of its leather bowl-shaped bottom to connect to the adsorption chamber, and the hole center line of the connecting jack coincides with the hole center line of the air suction hole or is set at a right angle.

[0011] Furthermore, the diameter of the air intake hole is larger than the diameter of the connecting jack.

[0012] Furthermore, the cup-shaped end of the adsorption contact portion is flush with each other and perpendicular to the center line of the suction hole.

[0013] The beneficial effects of the present invention are as follows: in view of the material properties of the conductive silicone rubber, which has the characteristics of low volume resistivity (generally 3 to 10Ω.cm), low hardness, high and low temperature resistance (-70℃ to 200℃), aging resistance, good elasticity, and good processing and manufacturing processability, the conductive silicone rubber is used to form the suction cup body in one piece, and the adsorption contact part is used to perform negative pressure adsorption with the patient's skin, and the adsorption chamber generates negative pressure, and then the electrode connection line and 3.5 needle head of the electrocardiograph are plugged and positioned through the connecting jack. Due to the good elasticity of the conductive silicone rubber, the electrode connection line and the 3.5 needle head form an interference fit with the connecting jack, so that the adsorption chamber and the adsorption contact part can perform negative pressure adsorption with the patient's skin well without falling off. After the test is completed, the electrode connection line and the 3.5 needle head are removed from the connecting jack, and after the connecting jack is connected to the outside air for pressure relief, the entire suction cup can be easily detached from the patient's skin. The operation is simple and does not cause negative effects such as pain to the patient. It is scientific and reasonable.

[0014] The entire suction cup assembly is integrated, manufactured and used as a whole, is reusable, has controllable suction, and reliable adsorption, and simple negative pressure relief does not affect the patient. Therefore, it is very suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS
