The scleral epimacular implant comprises an arm (6) with a curved configuration, having a first end (1), which can be affixed to a retina (8). The arm (6) comprises a second end (3) comprising a discoidal element (4), whose internal face facing the curvature of the arm (6) is constituted as an indentation platform (5), configured to be in contact with the retina (8) when the implant is placed in said retina (8).

The invention provides a medical hydrocolloid dressing and a preparation method thereof. The medical hydrocolloid dressing is prepared from, by total mass percentage, 30-60% of an adhesive, 20%-50% ofsodium carboxymethyl cellulose, 0.5%-20% of bioactive glass, 0.5%-10% of beeswax, 0.5-30% of olive oil, and 0.5-40% of microcapsule wall materials. The hydrocolloid dressing can be widely used, is suitable for protecting and treating various surface wounds including ulcers, diabetic feet, lower extremity venous / arterial ulcers, pressure sores, post-operative incisions, skin donor site wounds, burn wounds and the like, and has the effects of alleviating wound bleeding, relieving inflammation and pain, effectively absorbing exudates, maintaining a moist environment, promoting rapid wound regeneration and healing, and preventing and reducing scars.

The invention discloses a gas delivery system for hepatic perfusion. A control module of the gas delivery system controls an oxygen delivery control component and a compressed air delivery control component to work according to output results of a hepatic artery neural network training model and a portal vein neural network training model, real-time detection results of a hepatic artery detectionmodule and a portal vein detection module are trained based on the neural network training models, preset oxygen partial pressure, partial pressure of carbon dioxide and blood oxygen saturation degree, and hepatic artery and portal vein gas delivery capacity can be accurately adjusted in real time, so that the oxygen partial pressure, the partial pressure of carbon dioxide and the blood oxygen saturation degree are stably outputted according to preset values. Moreover, universal wheels are arranged at the bottom of a base, so that the gas delivery system can be used and mounted in different surgical places. In addition, when the storage capacity of gas in an oxygen storage bottle and a compressed air storage bottle reaches critical values, an alarm module can timely inform operators of related information.

The invention relates to a formula of traditional Chinese medicine, especially a foot flooding medicament for treating hyperosteogeny. The formula is used in treatment of hyperosteogeny, especially cervical vertebra hyperosteogeny, with the functions of increasing cerebrovascular flow, reducing blood vessel resistance, improving brain blood supply, improving microcirculation, expanding blood vessel and fine artery, reducing blood viscosity, preventing plug and removing plug; it also can improve the functional obstacle caused by ischaemia.

The invention provides a carotid artery in-situ fenestration balloon sheath. The carotid artery in-situ fenestration balloon sheath comprises a balloon sheath body, a sheath core and an injection device. The balloon sheath body is of a hollow structure with a through head and tail and comprises a first balloon, a sheath tube front section, a second balloon, a sheath tube rear section and a sheath tail, and the first balloon is an annular balloon and can expand outwards after being filled; the second balloon is of a hollow flexible bendable structure; the sheath tube front section, the sheath tube rear section and the sheath tail are of hollow tubular structures; the first balloon, the sheath tube front section, the second balloon, the sheath tube rear section and the sheath tail are fixedly connected and communicated in sequence; a third balloon is fixed in the sheath tail; the sheath core is of a hollow structure with holes in the head and the tail, and the head of the sheath core is conical. The sheath core is inserted into the balloon sheath body through the third balloon, and the head of the sheath core penetrates out of the first balloon; the injection device is communicated with the first balloon, the second balloon and the third balloon and is responsible for injecting liquid into the first balloon, the second balloon and the third balloon; after the third balloon is filled, the inner wall of the balloon is tightly attached to the sheath core.
