摘要： PURPOSE:To quickly fill a proper quantity of biomedical cement at a preset position without increasing an operation invasion by providing a storage section communicated with an opening section and storing biomedical cement and a high-pressure fluid ejecting means connected to the storage section and discharging the biomedical cement from the opening section. CONSTITUTION:A cement storage cartridge 12 storing biomedical cement inside is screwed to a cement discharge cartridge 11 having an opening section 11a discharging the biomedical cement, and a pressure regulator 16 and a compressor 17 connected to the cement storage cartridge 12 via a flexible connecting pipe 15 are provided to discharge the bio-medical cement in the cement storage cartridge 12 to a preset position from the opening section 11a. A piston 14 in the cement storage cartridge 12 is pushed by the high-pressure gas while the pressure is adjusted with pressure regulator 16, and a proper quantity of the biomedical cement is filled into the preset position from the opening section 11a while the quantity of the biomedical cement is measured with a scale.

摘要： PURPOSE:To obtain a cement for living body with excellent affinity to the living body which can be filled at an arbitrary location. CONSTITUTION:This cement comprises a powder agent mainly composed of a mixture of an alpha type third calcium phosphate and a first calcium phosphate so arranged to be 1.40-1.498 in Ca/Pmol ratio and a liquid agent and moreover, the powder agent contains 0.1-5wt.% apatite whisker per the total amount thereof and also, does second calcium phosphate. The calcium phosphate cement for living bodies uses the calcium phosphate cement of a specified composition rich in affinity to organisms and the apatite whisker as base material and hence, it has a high strength while being limited in strength variations with excellent affinity to the living bodies. Also excellence in fluidity and operability in kneading allows filling at an arbitrary location such as a part with a compplicated from or a narrow part.

摘要： PURPOSE:To obtain a cured body which rapidly cures at about neutral pH and has high strength and excellent bio-affinity by constituting the cured matter of the cement compsn. contg. a specific powder material mixture consisting of alpha type calcium ternary phosphate and calcium secondary phosphate and a hardening liquid and further compounding calcium primary phosphate with this compsn. CONSTITUTION:This hydraulic calcium phosphate cement compsn. is constituted of the cement compsn. contg. the powder material mixture of 1.400 to 1.498 Ca/P molar ratio of the alpha type calcium ternary phosphate and calcium secondary phosphate and the hardening liquid. In addition, the calcium primary phosphate is incorporated into the above-mentioned powder material mixture and/or hardening liquid. The curing is accelerated by further incorporating water-soluble sodium salts in addition to the calcium primary phosphate into the material mixture and/or hardening liquid. The above-mentioned curing liquid is not particularly limited and is exemplified by, for example, water.

摘要： PURPOSE:To enable good adhesiveness to a bone and a tooth to be exhibited by containing condroitin sulfuric acid or its salt in setting fluid for hardening hydraulic calcium phosphate cement. CONSTITUTION:Chondroitin sulfuric acid, having a sulfuric acid group and a carboxyl group, shows strong acid, but as a kind of principal mucopolysaccharides with hyaluronic acid, since condroitin sulfuric acid is contained 20 to 40% in cartilage, in addition, widely distributed in skin, navel string, other various binding tissue, etc., it has high affinity to the living body. Accordingly, the condroitin sulfuric acid can be used as it is, while for facilitating handling, as condroitin sulfuric acid salt. The condroitin sulfuric acid and its salt, providing molecular weight of 1000 to 50000 range and further with surface active action, is knead-mixed with hydraulic calcium phosphate cement, and this cement is adhesively well attached to bone and teeth. Also, by particularly improving consistency and operation workability at the time of kneading, operation is faciliated and further even a place of narrow space or complicated shape can be surely and closely filled with cement mud.
