  • Patent number: 12232932
    Abstract: The present disclosure belongs to the field of treatment devices, and specifically relates to a medicated thread drainage treatment device. The treatment device includes a first treatment unit used for postoperative pain relief and drainage; a second treatment unit used for promoting quick healing of a wound; a third treatment unit used for preventing deep venous thrombosis; and an electropneumatic, negative-pressure, electric stimulation multipurpose therapy apparatus connected with the first treatment unit, the second treatment unit, and the third treatment unit and providing electropneumatic pressure, negative pressure, and electric energy. The present disclosure is used for postoperative quick healing and recovery; promotion of clinical use guidelines will greatly reduce and even eliminate the postoperative complications, particularly postoperative complications of pulmonary embolism, thus saving patients' lives.

  • Publication number: 20240099893
    Abstract: The present invention discloses a tubeless energy drainage device for trauma, pertaining to the field of tubeless drainage technology, especially relating to a tubeless energy drainage device for trauma. The device includes energy transmission carriers, lead wires, and a frequency electrical energy generator. The frequency energy resonance generator transmits electrical energy to the energy transmission carriers, activates metal potassium ions on the energy transmission carriers, and creates resonance through conduction of metal ions in a wound covering layer and changing frequency of a wound, thereby achieving retrograde drainage of the wound's own sinus in a drainage area. The device disclosed by the present invention is of great significance for the rapid and full drainage of intractable wounds and battlefield wounds, and the drainage, healing, and pain relief of minute wound fistulas that cannot be tubed.

  • Patent number: 10975284
    Abstract: A well cementation working solution prepared from red mud, slag and waste drilling fluids. The working solution is prepared from the following components in parts by weight: 100 parts of waste drilling fluids, 50-100 parts of slag, 5-50 parts of red mud, 4-7 parts of a suspension stabilizer, 1-7 parts of an activating aid, 0.5-5 parts of an anti-pollution agent and 0.4-3.5 parts of a diluent. The waste drilling fluids are waste waterborne drilling fluids. The slag is blast furnace slag or vanadium-titanium slag. The suspension stabilizer is sodium bentonite, carboxymethyl cellulose or a mixture of sodium bentonite and carboxymethyl cellulose. The activating aid is sodium metasilicate nonahydrate, sodium carbonate or a mixture of sodium metasilicate nonahydrate and sodium carbonate. The anti-pollution agent is sodium salicylate, potassium citrate or a mixture of sodium salicylate and potassium citrate. The diluent is sodium lignin sulfonate.

  • Publication number: 20180144951
    Abstract: A method to reduce the number and type of processing steps to achieve conductive lines in the planes of a substrate concurrently interconnecting conductor through the substrate, by forming structures in the planes of a substrate. These structures may include interconnect lines, bond pads, and other structures, and improve the performance of subsequent unique processing while simultaneously reducing the manufacturing complexity to reduce time and cost. These structures are formed by selective etching using chemical mechanical polishing, and then completed using a single fill step with a conductive material.
