What happens: Omron compatibility

The OK Prostate Chip is a small device placed in the urethra, the urine passage, to act on the prostate. These entries discuss electrode versions, meaning chips with electrical contacts, intended to receive stimulation from an Omron low-frequency unit. The diary includes both urethral chips and rectal chips, with contacts on or within the chip body. Cables and connectors provide the connection to the external unit, while the entries track changing designs and questions about whether particular parts fit.

An early Omron connection request exposed problems with pads and metal

In an entry published in December 2018, a customer requested a rectal chip with electrodes. The customer said Omron's plug matched a standard stereo mini plug (a cable connector). They reported that treatment pads lacked durability and transferred stimulation poorly to internal tissue.

They described a proposed exposed metal width of 1cm–1.5cm. Mr. Okada made a prototype, but his newly ordered Omron unit had not arrived, so he could not test it. His initial reply made testing a condition of accepting the custom work.

Snap button connections carried separate component charges in April 2019

An entry published in April 2019 priced snap button connections (button-style electrical links) at ¥4,000, (about $26 at ¥156 = $1, rate as of 2026-09-04) excluding tax, beyond the chip price. Its components were an aluminum electrode at ¥1,000 (about $6 at ¥156 = $1, rate as of 2026-09-04), a chip-shaped button terminal at ¥2,000 (about $13 at ¥156 = $1, rate as of 2026-09-04), and a cable connection at ¥1,000 (about $6 at ¥156 = $1, rate as of 2026-09-04). These component prices also excluded tax.

The same entry gave complete electrode-equipped examples: a single-bump rectal chip at ¥9,000 (about $58 at ¥156 = $1, rate as of 2026-09-04) and a semi-long glass chip at ¥7,000 (about $45 at ¥156 = $1, rate as of 2026-09-04), excluding tax. A short resin example was ¥5,000, (about $32 at ¥156 = $1, rate as of 2026-09-04) excluding tax, as published in April 2019. Mr. Okada directed custom requests to email.

An Omron connection could not use a snap on only one side

In an entry published in August 2019, a customer requested a semi-long resin urethral electrode and a single-bump U-shaped rectal electrode. The request specified nylon reinforcement on the urethral version and 70cm cables. The maker quoted ¥7,560 (about $48 at ¥156 = $1, rate as of 2026-09-04) for the urethral electrode and ¥9,720 (about $62 at ¥156 = $1, rate as of 2026-09-04) for the rectal electrode.

The diary does not record how this pair worked in use. The maker said Omron's specifications required matching snap connectors on both of the 2 poles (electrical contacts).

The maker's Omron compatibility answer named a specific test model

In an entry published in December 2022, a customer asked whether the plug on a modified resin chip would work with an Omron unit. The quotation included ¥4,400 (about $28 at ¥156 = $1, rate as of 2026-09-04) for electrode processing on two contacts. A 70cm cable and the connection plug were priced at ¥1,100 (about $7 at ¥156 = $1, rate as of 2026-09-04) each.

The entry records a quotation, without an account of the customer's later use. The maker answered that all its electrode chips had been tested with the Omron Elepuls HV-F127 (the named electrical stimulation unit).

Nylon reinforcement changed the maker's answer about stainless steel Omron connections

An entry published in August 2023 revisited a customer's request for a stainless steel electrode chip. Staff initially declined, citing difficulty attaching the electrical connection and delayed stainless steel stock. The customer clarified that the whole steel chip could form a single pole, with a cable attached.

Mr. Okada later reported that a very fine cable reinforced with nylon made the connection feasible, and he considered offering it. He described a snap connector intended for Omron equipment, while also allowing an unfinished cable end for the custom request. Mr. Okada made the cable's strength guarantee conditional on retaining its nylon reinforcement.

The maker's answer to Omron compatibility

Mr. Okada answered through design restrictions, connector checks, and quotations for the requested electrical work.

Mr. Okada restricted Omron connections because of his concerns about electrical faults

In an entry published in April 2019, Mr. Okada addressed faults involving electrode chips and the external unit. He wanted at least 500Ω of electrical resistance (opposition to current) between poles, even if the unit malfunctioned. The diary does not record measured resistance for each customer's arrangement.

He said urine could bridge the poles of a two-pole urethral chip, creating an unwanted electrical connection. He also said using other terminals left responsibility with the user if the unit failed. Mr. Okada restricted electrode orders to a single pole per body cavity.

Larger snap button connections required supplied parts and had limited testing

In an entry published in September 2024, Mr. Okada said he had supplied electrodes only with Omron-compatible plugs or snap connectors. He completed a larger-connector version after a customer supplied the actual button. He had no suitable unit for testing that alternative connection.

He offered only a continuity test (a check that the connection conducts electricity), not an operating test with that machine. Mr. Okada said customers requesting large connectors needed to obtain the buttons and send them to OK Lab.

Stainless steel Omron connections gained cable options with individually quoted surcharges

In an entry published in December 2024, a customer requested a custom electrode based on the sculpted surgical stainless steel chip. Staff accepted the unfamiliar work, and Mr. Okada reported a strong connection through an intermediate wire. He began offering stainless steel connections to parallel cable (paired wires running side by side).

The options included direct snap connections and connections through a USB connector (a detachable cable junction) described as suitable for boiling. Electrical work added a surcharge to standard cable-connection prices and custom loop assembly prices. Mr. Okada said staff would quote each configuration individually.

Common worries about Omron compatibility

Customer questions concerned custom quotations, connector fit, and whether unusual electrical arrangements could be verified.

"Could I order an Omron connection with a short resin chip?"

An entry published in August 2019 records a separate request for a short resin urethral chip and a single-bump U-shaped rectal chip. Mr. Okada quoted ¥12,280 (about $79 at ¥156 = $1, rate as of 2026-09-04), including electrode work and plug processing.

The quote listed ¥1,080 (about $7 at ¥156 = $1, rate as of 2026-09-04) for the resin chip and ¥5,400 (about $35 at ¥156 = $1, rate as of 2026-09-04) for the rectal chip. Electrode processing was ¥2,160 (about $14 at ¥156 = $1, rate as of 2026-09-04) per chip, while plug processing was ¥1,080 (about $7 at ¥156 = $1, rate as of 2026-09-04). The diary does not record whether that quoted order was completed.

"Will an existing cable fit the Omron snap button connection?"

In an entry published in September 2024, a customer asked for a larger snap connector to fit a cable they already owned. They requested 3.5mm, while accepting the earlier 2.3mm size as a fallback.

The customer reported that Omron's supplied cable used 2.3mm buttons matching OK Lab's standard connector. Mr. Okada paused work because the requested larger connector was not in stock.

"Can an Omron connection have two buttons on one electrode?"

In an entry published in October 2024, a customer requested two buttons on a single stainless steel electrode. The customer wanted a triphase connection (a connection intended to combine outputs), describing access for multiple machines. Staff measured the supplied button at 4mm, despite the original 3.5mm request.

They raised concerns about cable strength, unfamiliar construction, and their inability to verify operation. After clarification, Mr. Okada showed a finished assembly but said he did not fully understand the overlapping-wave explanation. The diary does not record how that arrangement performed with the customer's equipment.
