A method for producing vaginal electrodes by hollow blow molding patch

Abstract

This method produces vaginal electrodes. The thermoplastic material is extruded or injected to obtain a tubular plastic parison, which is placed in a split vaginal electrode mold while it is hot or heated to a softened state. The air blows the plastic parison and clings to the inner wall of the mold, adjusts the opening and maintains a certain pressure during the cooling period, demoulds after cooling, and trims the flash to obtain the vaginal electrode. The main body of the electrode is made of ABS, PVC, polyethylene, polypropylene and other insulating thermoplastic materials that can be used for hollow blow molding; the conductive part of the electrode is fixed on both sides of the electrode by polymer conductive materials such as conductive plastics and conductive silicone sheets. The invention has the following advantages: cost reduction can better realize one-time use, and avoids the influence of cross-infection and repeated use of repeated cleaning and disinfectant residues and precipitation of harmful substances.

Description

technical field [0001] The invention relates to a method for producing vaginal electrodes by hollow blow molding patches. Background technique [0002] Women's pelvic floor muscle dysfunction refers to the loss of pelvic organs from their normal anatomical position due to the defect or relaxation of pelvic floor support tissue. It is mainly due to gynecological diseases such as urinary incontinence, vaginal relaxation, vaginismus, and unsatisfactory sex life caused by pelvic floor muscle relaxation. At present, pelvic floor muscle dysfunction due to pelvic floor muscle relaxation is screened in advance, and those with abnormal pelvic floor muscle dysfunction are given biofeedback training and electrical stimulation therapy. Biofeedback training and electrical stimulation therapy is to insert vaginal electrodes into the patient's vagina, cooperate with the host that can generate pulsed ultra-low frequency electromagnetic fields, and perform biofeedback training and electrica...

AI Technical Summary

Problems solved by technology

The surface of the third type of electrode is smoother and has no butt joints, so there is no seepage into the electrode or cracking due to transportation bumps, but the processing is more cumbersome, the cost is higher, the weight of the product is increased, and the foreign body feeling is strong during use.

[0005] The above three products are all processed by injection molding. Compared with the hollow blow molding method, the product weight cannot be reduced, the product efficiency cannot be improved, and the product cost is also higher, because the waste rate of inlay injection molding is also higher.
