Problems solved by technology

[0003] 1. The coupling of salt water is poor, resulting in a small discharge between the electrode and the skin, which is easy to burn the skin;
[0004] 2. The moisture retention of salt water is poor, resulting in poor stability of electrical signal output and affecting the therapeutic effect of the equipment;
[0005] 3. Salt water is highly corrosive, and it is easy to corrode the electrode after repeated use, causing damage to the electrode and affecting the service life of the equipment

Embodiment 1

[0039] Example 1: If the viscosity of the conductive preparation is required to be less than 50mm 2 / s, the following ratio is used;

[0040] The proportion of distilled water is 96% to 99%, the proportion of sodium chloride is 0.5% to 0.6%, the proportion of povidone iodine is 0.001% to 0.0025%, and the proportion of 1,2 propylene glycol is 1% to 2 %, the proportion of polyethylene glycol is 1% to 2%, and the proportion of sodium carboxymethyl cellulose is 0.5% to 0.6%. The conductive agent fused in this proportion has strong permeability and can fully infiltrate the conductive medium. In cotton, when used in conjunction with electrodes, the weak conductivity can effectively conduct electricity, avoiding skin burns that may be caused by excessive current stimulation of the skin. of treatment equipment.

Embodiment 2

[0041] Example 2: If necessary, the viscosity of the conductive preparation is 50-100mm 2 / s, the following ratio is used;

[0042] The proportion of distilled water is 93% to 96%, the proportion of sodium chloride is 0.6% to 0.8%, the proportion of povidone iodine is 0.001% to 0.0025%, and the proportion of 1,2 propylene glycol is 2% to 4%. %, the proportion of polyethylene glycol is 2% to 4%, and the proportion of sodium carboxymethyl cellulose is 0.6% to 2%. It has a certain adhesion and is suitable for coating directly on the skin or on the surface of the electrode contacts. It is mainly used for diagnosis and treatment equipment such as electrocardiographs and defibrillators.

Embodiment 3

[0043] Example 3: If necessary, the viscosity of the conductive preparation is 5000-30000mm 2 / s, the following ratio is used;

[0044] The proportion of distilled water is 90% to 93%, the proportion of sodium chloride is 0.8% to 1%, the proportion of povidone iodine is 0.001% to 0.0025%, and the proportion of 1,2 propylene glycol is 4% to 6%. %, the proportion of polyethylene glycol is 4% to 6%, and the proportion of sodium carboxymethyl cellulose is 2% to 3%. The conductive agent fused in this proportion has high viscosity and stability during use. It has good characteristics and is suitable for being directly coated on the surface of the electrode contact, and the electrode can be attached to the active part of the body. It is mainly used for medical testing equipment such as brain wave detectors.

[0045] Specifically, a stirring device was used for fusion in the preparation process, and the conductive preparations were all manufactured in the range of 25°C.

Abstract

The invention belongs to the field of conductive preparations, and discloses a polymorphic multifunctional medical conductive preparation, which comprises a stirring device and the following components: distilled water, sodium chloride, povidone iodine, 1, 2-propylene glycol, polyethylene glycol and sodium carboxymethyl cellulose. The problem of conduction between electrodes of various medical devices and the skin can be effectively solved, stable electric signal output is formed, accurate diagnosis data and treatment effects are obtained, residues on the inner wall of the stirring kettle can be cleaned through the arranged spraying mechanism, and the spraying mechanism is convenient to use. And then the scraping plate is started according to the actual situation to scrape the inner wall of the stirring kettle, so that personnel can conveniently clean the interior of the stirring kettle.

Description

technical field [0001] The present invention relates to the field of conductive preparations, and more particularly, to a polymorphic and multifunctional medical conductive preparation. Background technique [0002] At present, the medical conductive pastes on the market are suitable for physical diagnosis and monitoring instruments, and they are all paste media with high viscosity. There is no liquid conductive medium with low viscosity suitable for electrotherapy equipment, and users mostly use physiological saline as the conductive medium, but the main problems in the use of physiological saline as a conductive medium are as follows: [0003] 1. The coupling of salt water is poor, which leads to a small discharge between the electrode and the skin, which is easy to burn the skin; [0004] 2. The poor moisturizing property of salt water leads to poor stability of electrical signal output and affects the therapeutic effect of the device; [0005] 3. Salt water is highly c...
