8 patents, blood flow detection direction defined by Bestman

In the first half of 2024, Shenzhen Bestman Precision Instrument Co., LTD. (referred to as "Bestman"), a NASDAQ IPO listed company, successively obtained 8 core invention patents of "blood flow rate detection" and other categories. Earlier this year, the company publicly disclosed its prospectus with the US Securities and Exchange Commission (SEC) under the ticker symbol BSME.

Bestman  has a first-mover advantage in the field of blood flow testing equipment, and its multiple models of blood flow testing equipment have strong international competitiveness, not only leading in domestic technology, but also second to none in the international market. This time, the approval of a number of invention patents for blood flow detection technology will further consolidate Bestman's advantages as the industry leader in blood flow detection equipment, and if it can complete the financing of the Nasdaq IPO in the near future, it will help it become a "unicorn" company in a new segment.

The eight invention patents are summarized as follows:

Invention name: A blood pressure detection device

Abstract: The invention discloses a heating infusion device with an intelligent control module, comprising a control box. The lower side of the control box is provided with a heating module, the upper side of the control box is provided with a fixed device, and the lower end of the heating module is provided with a silicone insulation pipe. The liquid is heated through the heating module, and the heating process is adjusted in real time through the control box to ensure that the temperature of the liquid is always in the most suitable state for the human body, avoiding the hypothermia of the patient. Besides, after the liquid leaves the heating module, it will go through a long infusion tube before reaching the human body. If it is directly exposed in the air, part of the heat will be lost. The temperature entering the human body does not reach the target value, and the silicone insulation pipe can be set to keep the temperature close to the human body temperature to achieve the insulation effect.
