Problems solved by technology

[0004] Existing vaginal electrodes usually have a smooth drop-shaped structure, using metal parts such as stainless steel sheets as conductive electrodes embedded in the matrix, and the internal conductive electrodes are directly connected to the test instrument through signal lines. The overall structure is relatively complicated and the preparation cost is high.
Due to the high cost of product preparation, one-time use cannot be tolerated, so a test instrument is usually equipped with a vaginal electrode, which is used alternately between different patients
Cross-use between different patients will have the following problems: 1. Disinfection is required before reuse after use, and there is a risk of cross-infection if disinfection is not complete; 2. Disinfectant is also likely to remain on the vaginal electrode, and the residual disinfectant will irritate the vagina Mucous membranes, causing harm to the patient

Abstract

The invention provides a vaginal multi-contact electrode containing graphene oxide-silver nanocomposite. The vaginal multi-contact electrode containing the graphene oxide-silver nanocomposite comprises a spindle-shaped shell, two pressure sensing strips, a first contact, a second contact and a connecting wire. The shell is prepared from a graphene oxide material, and the first contact and the second contact are made of materials containing the graphene oxide-silver nanocomposites; the pressure sensing strips are of belt-shaped structures prepared from medical pressure sensors and penetrating through the two ends of the spindle-shaped shell; the pressure sensing strips are symmetrically distributed on two sides of the shell, and the first contact and the second contact are annular and are embedded on the outer wall of the shell; and the insides of the pressure sensing strips, the first contact and the second contact are connected with the connecting wire, and are connected with a signalwire of a test instrument through the connecting wire. The vaginal multi-contact electrode disclosed by the invention is simple in structure and convenient to operate, and can be used together with an external source controller to realize effective self-diagnosis and treatment of patients without medical intervention or guidance of physicians.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vaginal multi-contact electrode containing graphene oxide-silver nanocomposites. Background technique [0002] Pelvic floor dysfunction is a common disease among middle-aged and elderly women, which seriously affects women's physical and mental health and quality of life, and has become one of the five common chronic diseases that threaten women's health. Pelvic organ dysfunction occurs, and the patient has a series of clinical symptoms such as pelvic organ prolapse, stress urinary incontinence, and defecation disorders. The pathogenesis of pelvic floor dysfunction diseases may be caused by the progressive impairment of pelvic floor support function under the combined action of biomechanics, reproductive endocrine changes, and connective tissue metabolism of pelvic floor connective tissue, muscles, and nerves. Electrophysiological stimulation technology includes the de...
