A61B 5/154 - Devices for taking samples of blood specially adapted for taking samples of venous or arterial blood, e.g. by syringes using pre-evacuated means
A fixing jig (10) has a frame body (11) that is capable of holding a bag (50). The frame body (11) has engagement parts (26a, 26b) which engage engagement claws (65a, 65b) of a bottle needle (60) being connected to a discharge port (53) of the bag (50) and which are for maintaining a connection state with the bottle needle (60). The fixing jig which is fixed to the discharge port (53) made of a soft material comprises: first engagement parts (23c, 23d) that are made of a material harder than the material of the discharge port (53), that can be attached to the discharge port (53), and that are capable of engaging, when attaching thereto the discharge port (53), a first counter engagement part (55) which is formed in the discharge port (53); and second engagement parts (26a, 26b) which are capable of engaging second counter engagement parts (65a, 65b) formed in the bottle needle (60). The bottle needle (60) is prevented from slipping off of the discharge port (53) via the first engagement parts (23c, 23d) and the second engagement parts (26a, 26b).
[Problem] To facilitate operation of a nucleic acid extraction container. [Solution] The present invention is provided with: a closed-ended cylinder-shaped body 10 that has a first opening at one end; and a column 20 that is inserted into the body 10 via the first opening of the body 10. The body 10 has a tapered section 120 that protrudes radially outward from a first outer peripheral surface of the body 10 at the periphery of the first opening, the external diameter of the tapered section 120 decreasing from the bottom toward the first opening in an axial direction of the body 10. The column 20 comprises: a cylindrical section 210 that is inserted into the body 10 and has, at the two ends thereof, a second opening and a third opening; a nucleic acid trapping member 30 that is accommodated in the cylindrical section 210; and an expanded section 220 that protrudes radially from a second outer peripheral surface of the cylindrical section 210 on the second opening side and is in contact with the periphery of the first opening.
A sprayer includes a barrel, a finger grip, a gasket, a rod, and a plunger slidably attached to the rod and capable of contacting the rod and pressing the rod toward a distal side. The plunger includes a contact member which is brought into contact with the finger grip, and a first pressing surface provided at a proximal end thereof. The rod includes a second pressing surface provided at a proximal end thereof. The contact member is brought into contact with the finger grip to restrict the movement of the plunger toward the distal side with the gasket positioned between a distal end and a proximal end of the barrel.
This glass pipe cutting device 10 comprises: a transport unit 50 that transports a continuous pipe-like body along an axial direction of the pipe-like body; a measurement unit 200 that measures the radial size of the pipe-like body and the transport speed of the pipe-like body; and a cutting control unit 300 that controls a laser irradiation unit, which is provided, on the radially outer side of the pipe-like body, to a prescribed position in a circumferential direction of the pipe-like body at a distance apart from the pipe-like body. The cutting control unit 300 controls the irradiation direction and timing at which the pipe-like body is irradiated with laser light from the laser irradiation unit on the basis of the radial size and the transport speed of the pipe-like body, these items of information being held as data that is measured by the measurement unit 200 or calculated in advance.
The present invention provides a medical shaft which has a novel structure and which makes it possible to fit, to a fixed position, a resin tube that covers a region of a shaft body from a small-diameter portion to a large-diameter portion, while suppressing the occurrence of problems caused by an increase in diameter. Provided is a medical shaft 10 wherein: a shaft body 12 is provided with a change part 37 in which the outer diameter dimension changes between a small-diameter portion 34 and a large-diameter portion 36; a region of the shaft body 12 which is from the small-diameter portion 34, through the change part 37, and to the large-diameter portion 36 is continuously covered in the lengthwise direction by a resin tube 14; the resin tube 14 has a structure in which a small-diameter side heat-shrink tube 48 that covers the small-diameter portion 34 and a large-diameter side heat-shrink tube 50 that covers the large-diameter portion 36 are joined; and a joining part 46, which has a larger thickness dimension than one of the small-diameter side heat-shrink tube 48 and the large-diameter side heat-shrink tube 50, is positioned further to the small-diameter portion 34 side at which the change part 37 is positioned than an end part of the large-diameter portion 36 of the shaft body 12.
