Description

TECHNICAL FIELD

[0001] The present application relates to the field of power supply equipment, in particular to a medical negative plate. BACKGROUND

[0002] The medical negative plate refers to the plate with a more negative electrode potential in the circuit. The negative plate of the electrotome (i.e. the ground plate and neutral electrode) can provide a safe return path for the electrosurgical current. The general negative plate is composed of a conductive glue area with a non-conductive frame glue around the periphery. The back of the general negative plate is fluid resistant. The general negative plate can only be used once and is a sterile product. The general negative plate has two configurations, with or without a wire.

[0003] However, the commonly used medical negative plate is easily soaked by liquid during the operation of the patient, such as using a high-frequency electrode to cut tissue during the operation. In addition to the sweat on the surface of the skin, if liquid flows into the conductive layer of the negative plate during the operation, a surgical medical accident of tissue burn will occur. SUMMARY

[0004] The present application provides a medical negative plate with good hydrophobic performance, large hydrophobic amount and good water resistance.

[0005] In order to achieve the above purpose, the present application adopts the following scheme:

[0006] A medical negative plate comprises a sticking layer and a conductive layer arranged in the middle of the sticking layer, wherein the conductive layer is provided with a touch plate, a conductive layer air hole, and conductive glue arranged at the bottom of the touch plate; the edge of the conductive layer is provided with a hydrophobic baffle ring to isolate the conductive layer and the sticking layer; the sticking layer is provided with sticking layer glue and a sticking layer middle ring; the conductive layer air hole does not penetrate the sticking layer; the outer side of the conductive layer is provided with two waterproof rings of the hydrophobic baffle ring and the sticking layer middle ring.

[0007] The present application also provides the following optimization scheme:

[0008] Preferably, the touch plate is arranged in the conductive layer.

[0009] Preferably, the conductive layer air hole is concave in the conductive layer.

[0010] Preferably, the conductive layer air hole is arranged in an array.

[0011] Preferably, the conductive layer air hole is circular.

[0012] Preferably, the sticking layer middle ring is arranged between the hydrophobic baffle ring and the outermost side of the sticking layer.

[0014] Preferably, the material of the sticking layer is a one-way water guide material.

[0015] Preferably, the material of the hydrophobic blocking ring is a hydrophobic material.

[0016] The medical negative plate has the following beneficial effects:

[0017] 1. The hydrophobic blocking ring on the medical negative plate can isolate the sticking layer and the conductive layer, preventing water in the sticking layer from flowing to the conductive layer.

[0018] 2. The sticking layer of the medical negative plate uses a one-way water guide material, which can absorb water on the inside and repel water on the outside. BRIEF DESCRIPTION OF DRAWINGS

[0027] As shown in Figure 1As shown, the adhesive layer 1 and conductive layer 2 are preferably shaped into a rectangle or a square, but can also be shaped into a circle or an ellipse. When the adhesive layer 1 is shaped into a rectangle, it is preferred that the four corners be rounded. Similarly, when the conductive layer 2 is shaped into a rectangle, it is also preferred that the four corners be rounded. The conductive layer 2 is preferably located at the center of the adhesive layer 1, and the four sides of the conductive layer 2 are equidistant from the four sides of the adhesive layer 1. The adhesive 12 is a commonly used ordinary adhesive and is non-conductive. The conductive adhesive 24 is a commonly used conductive adhesive.

[0028] like Figure 2 As shown, in a preferred embodiment, the contact plate 21 is disposed within the conductive layer 2. The vent holes 22 in the conductive layer are recessed within the conductive layer 2. Preferably, the vent holes 22 are recessed towards the inner side of the conductive layer 2.

[0033] In a preferred embodiment, the hydrophobic retaining ring 23 is made of a hydrophobic material.

[0034] Example

[0035] like Figures 1-4As shown, the medical negative plate of the embodiment comprises a sticking layer 1 and a conductive layer 2 arranged in the middle of the sticking layer 1, the conductive layer 2 is provided with a touch plate 21, a conductive layer vent hole 22, and a conductive adhesive 24 arranged at the bottom of the touch plate 21; a hydrophobic stop ring 23 is arranged at the edge of the conductive layer 2 to isolate the conductive layer 2 and the sticking layer 1; the sticking layer 1 is provided with a sticking layer adhesive 12 and a sticking layer middle ring 11; the conductive layer vent hole 22 does not penetrate the sticking layer 1; the outer side of the conductive layer 2 is provided with two waterproof rings of the hydrophobic stop ring 23 and the sticking layer middle ring 11. The touch plate 21 is arranged in the conductive layer 2. The conductive layer vent hole 22 is concave in the conductive layer 2. The conductive layer vent hole 22 is arranged in an array. The conductive layer vent hole 22 is arranged in a circular shape. The sticking layer middle ring 11 is arranged between the hydrophobic stop ring 23 and the outer side of the sticking layer. The conductive layer 2 and the sticking layer 1 are arranged in an arc shape at the four corners. The material of the sticking layer 1 is a one-way water guide material. The material of the hydrophobic stop ring 23 is a hydrophobic material.

[0036] The use method of the medical negative plate of the embodiment is as follows:

[0037] First, the inner side of the sticking layer 1 and the conductive layer 2 are pasted to the surface of the human body together, then the touch plate 21 contacts the human body, the conductive layer 2 is in communication with the electrode, and the life parameters of the human body are detected. When there is sweat or blood flowing on the surface of the human body; if the liquid is on the inner side of the sticking layer 1 and the outer side of the conductive layer 2, the sticking layer 1 can directly absorb the liquid from the inner side, if the liquid is on the outer side of the sticking layer 1, the sticking layer middle ring 11 of the sticking layer 1 can block most of the liquid, if a small amount of liquid enters the inner side of the sticking layer middle ring 11, the hydrophobic material of the sticking layer 1 can also expel the water out of the sticking layer 1 area. If the liquid appears in the area of the conductive layer 2, the liquid is discharged through the conductive layer vent hole 22 to remove the liquid in the conductive layer 2. When a large amount of liquid flows from the outer side of the sticking layer 1 for a short time, the sticking layer middle ring 11 is used to block the liquid from flowing into the position of the hydrophobic stop ring 23, at this time, a large amount of liquid is in the sticking layer 1 and flows out of the sticking layer 1.

[0038] The above is only the preferred embodiment of the present application, it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application, the protection scope of the present application should be limited by the scope defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
