There is provided a safety indwelling needle comprising an inner needle unithaving an inner needle, an inner needle hubprovided on a proximal end of the inner needleand a needle protecting member disposed at a distal side of the inner needle hub, and an outer needle unithaving an outer needle, characterized in that the needle protecting member includes an extendable housing unitand the housing unitcan partly store the inner needletherein in a state where the housing unitis extended.

Safety indwelling needle

A safety indwelling needle including an inner needle unithaving an inner needle, an inner needle huband a housing memberdisposed at a distal side of the inner needle hub, and an outer needle unithaving an outer needle, an outer needle huband an outer needle cap, characterized in that the housing memberincludes openings for allowing penetration of the inner needleat a distal end and a proximal end thereof, an internal space for storing only a distal end portion of the inner needleincluding a needlepointthereof when the inner needleis drawn out from the outer needle, and a shielding member which automatically closes the opening at the proximal end of the housing memberby a magnetic force.

A catheter for artificial insemination which is a hollow cylindrical catheter having open ends at both ends, the catheter comprising a small diameter portion forming a distal end portion, a large diameter portion forming a proximal end portion and a tapered portion connecting the small diameter portion and the large diameter portion, a total inner volume of the catheter being from 0.2 to 1.0 ml.

Catheter for artificial insemination

An infusion container comprising a communication port capable of being connected with a syringe, a container main body, a communication channel for providing communication between the inside of the container main body and the inner lumen of the communication port, and a sterilization filter provided in the communication channel, wherein the communication port is closed with a rubber stopper provided with a slit allowing the top end tip of the syringe to pass therethrough and the communication channel is closed with a closing means capable of being easily opened.

Infusion container

Filter for medical purpose

A filter set for recovering desired blood components from human blood and a method for recovering blood components using the filter set are provided. The filter set includes a bag body and an accommodation vessel for accommodating the bag body therein in a compressed condition. In the method the bag body is provided in the accommodation vessel and is compressed and blood is passed through the compressed bag body. Blood components are adhered to the compressed filter material in the bag body. Thereafter, the compression of the bag body is relieved and a washing solution is passed through the expanded bag body to remove the blood components contained therein.

Blood filter set and a method of recovering blood components using the

The present invention provides a blood component-recovering apparatus and a method for high-yield recovery of leukocytes captured in a filter of the blood component-recovering apparatus. The blood component-recovering apparatus includes a housing accommodating (a) a filtration portion charged with (b) a filter which is capable of passing erythrocytes but capturing leukocytes and (c) a pressing member for pressing the filter, the housing being provided in the sidewall thereof with (d) a blood flow inlet and (e) a blood flow outlet communicating with the filtration portion. The housing of the blood component-recovering apparatus is further provided in the upper wall thereof with (f) a means capable of transferring, or moving, the pressing member vertically. The pressing member of the blood component-recovering apparatus is transferred downward while a blood containing blood components is passed through the filtration portion. The pressing member is then transferred upward to increase the volume of the filtration portion, and a washing solution is then passed through the filter to recover leukocytes.
