Actual results could differ from those estimates. Presentation of Taxes Collected from Customers Sales taxes are imposed on the Company’s sales to nonexempt customers. The Company collects the taxes from customers and remits the entire amounts to the governmental authorities. The Company’s accounting policy is to exclude the taxes collected and remitted from revenues and expenses. Shipping and Handling Shipping and handling charges billed to customers are recorded as revenue. Shipping and handling costs are recorded within cost of goods sold on the statement of operations. Advertising Advertising costs are expensed as incurred. Advertising expenses were $37,060 2017, $71,212 2016. Research and Development Research and development costs are charged to operations as incurred. Research and development costs were approximately $289,000 $406,000 2017 2016, Revenue Recognition The Company recognizes revenue in accordance with the SEC’s Staff Accounting Bulletin Revenue Recognition and ASC 606 We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists – we receive both a signed purchase order and contract of terms and conditions confirming the sale from the customer; delivery has occurred – the goods are shipped from our warehouse and delivered and accepted by the customer; the selling price is fixed or determinable – confirmed on the customer purchase order and then invoiced immediately upon shipment of the goods; and collectability is reasonably assured – our customers are long standing hospitals, ambulatory surgical centers and others that pass credit checks. The terms of our agreements with our customers are specified in written agreements. These written agreements, the purchase order and the matching invoice, constitute the persuasive evidence of the arrangements with our customers that are a precondition to the recognition of revenue. We undertake an evaluation of the creditworthiness of both new and, on a periodic basis, existing customers. Based on these reviews we determine whether collection of our prospective revenue is probable. We have adopted the provisions of Accounting Standards Update, or “ASU” 2014 09, 606 606 January 1, 2018 While we continue to assess all potential impacts of the standard, it is currently anticipated that the standard will not Cash Equivalents The Company considers all highly liquid debt instruments with a maturity of three Certificates of Deposit Short-term interest-bearing investments are those with maturities of less than one three one Investment Securities Readily marketable investments in debt and equity services are classified as available-for-sale and are reported at fair value with unrealized gains losses recorded in other comprehensive income. Unrealized gains are charged to earnings when an incline in fair value above the cost basis is determined to be other-than-temporary. Realized gains and losses on dispositions are based on the net proceeds and the adjusted book value of the securities sold, using the specific identification method. Fair Value Measurements Under generally accepted accounting principles as outlined in the Financial Accounting Standards Board’s Accounting Standards Certification 820, 820 three Level 1 Level 2 Level 3 no The Company uses observable market data, when available, in making fair value measurements. Fair value measurements are classified according to the lowest level input that is significant to the valuation. The fair value of the Company’s investment securities were determined based on Level 1 Receivables Receivables are reported at the amount the Company expects to collect on balances outstanding. The Company provides for probable uncollectible amounts through charges to earnings and credits to the valuation based on management’s assessment of the current status of individual accounts, changes to the valuation allowance have not Inventories Inventories are stated at the lower of cost or market, with cost determined on a first first December 31, December 31, Finished goods $ 62,932 $ 38,201 Raw materials 141,028 165,812 Work-In-Process 61,085 68,195 Total $ 265,045 $ 272,208 Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization.

Equity Incentive Plan The Company has an equity incentive plan, which allows issuance of incentive and non-qualified stock options to employees, directors and consultants of the Company, where permitted under the plan. The exercise price for each stock option is determined by the Board of Directors. Vesting requirements are determined by the Board of Directors when granted and currently range from immediate to three three ten Accounting for share-based payment The Company has adopted ASC 718 Compensation-Stock Compensation 718" 718 January 1, 2006 January 1, 2006. January 1, 2006, not ASC 718 Since the Company's common stock has no no 2 7 15 10 When an option or warrant is granted in place of cash compensation for services, the Company deems the value of the service rendered to be the value of the option or warrant. In most cases, however, an option or warrant is granted in addition to other forms of compensation and its separate value is difficult to determine without utilizing an option pricing model. For that reason the Company also uses the Black-Scholes option-pricing model to value options and warrants granted to non-employees, which requires the input of significant assumptions including an estimate of the average period the investors or consultants will retain vested stock options and warrants before exercising them, the estimated volatility of the Company's common stock price over the expected term, the number of options and warrants that will ultimately be forfeited before completing vesting requirements, the expected dividend rate and the risk-free interest rate. Changes in the assumptions can materially affect the estimate of fair value of stock-based consulting and/or compensation and, consequently, the related expense recognized. Since the Company has limited trading history in its stock and no first Valuation and accounting for options and warrants The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term.

Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition The Company recognizes revenue in accordance with the SEC’s Staff Accounting Bulletin Revenue Recognition and ASC 606 We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists – we receive both a signed purchase order and contract of terms and conditions confirming the sale from the customer; delivery has occurred – the goods are shipped from our warehouse and delivered and accepted by the customer; the selling price is fixed or determinable – confirmed on the customer purchase order and then invoiced immediately upon shipment of the goods; and collectability is reasonably assured – our customers are long standing hospitals, ambulatory surgical centers and others that pass credit checks. The terms of our agreements with our customers are specified in written agreements. These written agreements, the purchase order and the matching invoice, constitute the persuasive evidence of the arrangements with our customers that are a precondition to the recognition of revenue. We undertake an evaluation of the creditworthiness of both new and, on a periodic basis, existing customers. Based on these reviews we determine whether collection of our prospective revenue is probable.
