A hair implant anchor usable with a hair implant anchor deployment device for inserting one or more hairs into a tissue portion is provided. The hair implant anchor includes a holder configured to grip one or more hairs and one or more selectably deployable leaves formed with the holder. When the anchor is in its first configuration prior to implantation of the hairs, the leaves are constrained by the deployment device in a position generally parallel to an insertion axis, and in a second configuration, subsequent to implantation of the hair, the leaves adopt a position extended away from the insertion axis, thereby securing the holder and hair gripped thereby within the tissue portion. The invention also provides a method for use of the anchor, a hair implantation system, a multi-hair implantation system and a hair implantation assembly.

The invention discloses a composite pre-heater, which directly carries out heat exchange and reaction separation between high-temperature gas and low-temperature materials. The composite pre-heater comprises a partial cone chamber (1), a spurting chamber (2) and a separator (4), wherein the lower end of the partial cone chamber (1) is provided with a hot gas inlet, one side of the partial cone chamber (1) is provided with a material spreading valve (6), an opening of the upper end of the partial cone chamber (1) is fixedly connected with an opening of the lower end of the spurting chamber (2), an opening of the upper end of the spurting chamber (2) is fixedly connected with an opening of one side of the separator (4) through a pipeline, a material spreading plate (3) is arranged on the pipeline, the upper part of the material spreading plate (3) is provided with a material inlet, the upper end of the separator (4) is provided with a gas out let, the opening of the lower end of the separator (4) is fixedly connected with the material spreading valve (6) arranged on the partial cone chamber (1) through a pipeline, and a wind locking valve (5) is arranged on the pipeline. Through the partial cone structure, the invention reaches the multidirectional suspension rotation and spurting, and high-temperature materials can not scar and can not be blocked. In the suspension state, the materials have long dwell time through spurting and rotating, and the heat exchange efficiency is high.

The invention relates to an alginate dressing for treating bedsores and a preparation method thereof. The dressing has a double-layer composite structure, that is, it is composed of a bottom layer and a surface layer, the bottom layer is an alginate composite film layer, and the surface layer is a natural rubber film layer ; Its preparation method comprises the following steps: A, preparation of shark collagen solution; B, preparation of coaxial electrospinning outer layer solution; C, preparation of coaxial electrospinning core layer solution; D, spinning; E, crosslinking ; F, impregnation; G, preparation of epoxidized natural rubber film; H, composite. The dressing prepared by the invention has good biocompatibility, controllable growth mediation of synthetic biological materials, good hygroscopicity, anti-inflammatory and antibacterial properties, can improve local blood supply of wounds, promote tissue growth, and accelerate wound healing, showing It has good versatility, good porosity, soft and comfortable hand feeling, good compliance, easy to use, and is suitable for use in the field of modern biomedicine, especially in the fields of bedsore treatment and care.

An energy-saving and environment-friendly liquid sodium bicarbonate production process, the specific steps are as follows: A. charging, B. melting, C. detection, D. discharging, E. cooling, F. purification; a liquid sodium bicarbonate processing equipment, It includes a boiler, a liquid sodium sodium processing device is fixed on one side of the boiler, and a high-temperature liquid sodium sodium cooling output device is fixed on one side of the liquid sodium sodium processing device. The present invention utilizes the installation of a liquid sodium natron processing device and a high-temperature liquid sodium sodium cooling output device on the side of the boiler, so that a large amount of solid sodium sodium can be melted, and high-temperature and high-pressure liquid sodium silicate can be cooled and output. Compared with the traditional dissolution kettle and static autoclave, the liquid sodium sodium processing equipment has the advantages of fast dissolution of solid sodium hydroxide, energy saving, no scarring in the dissolution container, and for the dissolution of high modulus solid sodium carbonate, Due to the use of steam for dissolution, high silicic acid polymers are rarely produced, and the dissolved liquid sodium bicarbonate has a uniform concentration.
