Patent number: 9408975Abstract: An apparatus for operating a syringe has developed comprising: an upper semi-cylindrical tube section, semi-circular shaped locking groove and lower semi-cylindrical tube section. The upper semi-cylindrical tube section is integrally formed an upper head part with a threaded hole for axial movement. The lower semi-cylindrical tube section forms a top portion, intermediate portion and end portion. A diameter (Dc) at the intermediate portion larger than the diameter (Dtip) at end portion is gradually reduced from intermediate to end portion. The length of the tapered portion is same as that portion of the constant diameter. A tip portion has formed an opened semi-circular shape to simply overlap the syringe over the cartridge for easily snapping-in and out. The syringe piston moves downward with no reverse action when the piston press-unit is rotated, thus it is possible to inject the precise amount of medicine to a patient with constant pressure.Type: GrantFiled: September 6, 2013Date of Patent: August 9, 2016Inventors: Seok-Jung Kim, Cheong-Ho Chang, Jae-Deog Jang, Hyun-Shin Park, Sae-Bom Lee, Kyoung-Phil Byun

Publication number: 20090111087Abstract: The present invention relates to a method for separating bone marrow-derived nucleated cells for bone formation. The method comprises: the steps of: washing bone marrow; lysing red blood cells in the bone marrow; neutralizing the bone marrow lysate; purifying nucleated cells from the neutralized bone marrow; and mixing the nucleated cells with a maintenance buffer for bone formation. According to the invention, bone marrow-derived nucleated cells, which can be grafted into a site in need of bone formation or bone defect treatment, can be separated in a rapid and convenient manner. As a result, bone formation in emergency patients or patients, who require repeated surgical operations, can be effectively achieved by separating the nucleated cells for bone formation in surgical locations in a convenient and rapid manner and injecting the separated cells into the patients.Type: ApplicationFiled: June 23, 2006Publication date: April 30, 2009Inventors: Hyun-Shin Park, Jae-Deog Jang, Sae-Bom Lee, Cheong-Ho Chang

Publication number: 20070087032Abstract: A cartilage therapeutic composition is developed for clinical transplantation into articulatio genu (knee joints) or ankle joints. It has clinical significance for symptomatic cartilage defects of the femoral condyle (medial, lateral, or trochlear) and bone cartilage defects of the talus (anklebone) in human or animal hosts, The cartilage therapeutic composition comprises a mixture of components of chondrocytes isolated and expanded or differentiated from a host such as a human or animal, and thrombin and a fibrinogen matrix containing fibrinogen. An application of the cartilage therapeutic composition is that a mixture of thrombin, chondrocyte components and a fibrinogen matrix is injected into a cartilage defect region followed by solidification therein. It provides rapid healing and effective regeneration of cartilage without surgical operation. It has the merits of safety and simplicity by allowing the use of an arthroscope for transplantation.Type: ApplicationFiled: December 7, 2004Publication date: April 19, 2007Inventors: Cheong-Ho Chang, Chang-Kwon Ko, Jae-Deog Jang, Eun-Young Lee, Jeong-Yong Choi
