The two main types of stocks are common stock and preferred stock. Common Stock. This is the most common type of stock available to the public, hence the term “common stock.” A majority of the stocks are in fact issued in this form. When people discuss stocks in the market, they are usually referring to this type of stock.

Method and apparatus for treating wound using negative pressure therapy

Devices that employ external compression stocking-type garments in the treatment of edema, chronic wounds, deep venous thrombosis prevention or claudication all share a number of significant limitations. These include the frequent need for custom fitting to assure an appropriate fit, vigilant maintenance to assure a continued “good fit,” limited compliance with proper use by patients and difficulty of application. There is a large body of evidence demonstrating that patients often decline to wear the compressive stockings as prescribed or in the form that would be most beneficial because they find these devices to be difficult to put on and take off.Building on the limitations of existing therapies, and distilled lessons learned from the field of prosthetics and wound healing, the present invention employs vacuum-assisted negative pressure to provide compression and help pump fluid from the tissues of affected limbs. The device is embodied in the form of a flexible stocking-like garment that will utilize a pumping mechanism to generate negative pressure around the limb and thus create vacuum compression that will mobilize fluid in a limb and increase venous return to the heart. Through the use of a circumferential wrap, the present invention provides a major advance in both the distribution of vacuum and the securing of the device over the limb.

The invention discloses a square stock type artificial quartzite plate and a manufacturing method thereof. The square stock type artificial quartzite plate is formed by using natural quartzite and powder thereof as main fillers and using unsaturated polyester resin as an adhesive through the steps of stirring, vacuumizing and jolt-squeezing under the action of an auxiliary agent. Due to the adoption of the square stock type artificial quartzite plate, a gap of producing square stock type artificial quartzite in China is filled up and the history of production of the artificial quartzite is rewritten. Due to the successful development and the scale batch production of the square stock type artificial quartzite plates, the capacity bottleneck of short-time and large-batch engineering supplyof the sheet-type artificial quartzite is solved, the production efficiency of the quartzite plate is greatly improved, the production cost is reduced, the color difference probability is greatly reduced, the performance of a quartzite product is improved, the instrumentality of the quartzite product is enriched, the leap development of the artificial quartzite industry is promoted, and the conversion from sheet to square plate, from manual distribution to mechanical distribution, from high consumption to low cost and from low energy to high efficiency is realized.
