Abrégé
A cyclic variation of heart rate (CVHR) shape measurement device 2 is provided with CVHR detection means 18-30 and a CVHR shape property index acquisition means 32. The CVHR detection means 18-30 detect CVHR that appears periodically from time-series data showing the cycle or frequency of heart rate or pulse rate. The CVHR shape property index acquisition means 32 acquires at least one shape property index selected from among amplitude of cyclic variation (ACV), slope, ratio of ACV to duration and area, for the CVHR wave shape detected by the CVHR detection means.
A syringe (1B) comprises: a syringe body (1C) including a plunger (32) to be operated for injection of a drug solution; a cylindrical needle cover (11B) housing an injection needle (100A); and a spring (18) held in a compressed state by the needle cover (11B). The needle cover (11B) has seats (153A) and (155B) in a pair that abut on corresponding opposite ends of the spring (18) to restrict the position of the spring (18). Pushing in the plunger (32) further after injection deforms the seat (155A) to release restriction on the spring (18). The spring (18) free from the restriction abuts on the syringe body (1C). This biases the needle cover (11B) to move the needle cover (11B) to a position where the injection needle (100A) is housed.

This pre-use mixing prefilled syringe does not require a bypass unit comprising a concave portion in the inner surface of the outer tube. In order to shorten delivery time of a liquid between the two chambers separated by a gasket, non-rotator-shape engaging portions (12, 13) which complement each other are provided on the front end of a first gasket (4) and the back end of a second gasket (5), said gaskets stoppering the outer tube (2). By not allowing the two engaging portions (12, 13) to abut and engage during storage, a drug accommodation space is formed between the two gaskets (4, 5), and when delivering a liquid into the drug accommodation space from the liquid accommodation space formed in the rear end side of the first gasket (4), the inner pressure of the drug accommodation space is prevented from becoming excessively large.
Disclosed is a syringe provided with an injection needle which has a storage function, the syringe having high assembling workability and productivity. A syringe (1B) comprises a syringe main body (1C) which comprises a plunger (32) operated to inject a liquid medicine; a cylindrical-shaped needle cover (11B) which accommodates an injection needle (100A); and a spring (18) which is held by the needle cover (11B) in a compressed state. The needle cover (11B) comprises a pair of seats (153A, 155A) coming into contact with respective both ends of the spring (18) for position regulation, and is configured to cause deformation to the seat (155A) to release the regulation on the spring (18) when the plunger (32) is further pushed after injection. After the release of the regulation, the spring (18) comes into contact with the syringe main body (1C), and thereby urges the needle cover (11B) to move the needle cover (11B) to a position where the injection needle (100A) is accommodated.

In order to provide a pre-filled syringe whereby the time needed for injection is reduced while superior safety is achieved, a needle unit (1) of a pre-filled syringe mounted onto a vial comprises: a substantially cylindrical holding member (10) for a double-ended needle; a holder member (11) for grasping the holding member (10) by three columnar sections (111); and a holder member (12) for grasping the holding member (10) by three columnar sections (121), the holder member having a mounting section (125) for the vial; shortening in the axial direction is possible in a state where the columnar sections (111, 121) are arranged far from each other in the peripheral direction, but shortening in the axial direction is not possible in a state where distal end surfaces of the columnar parts (111, 121) are facing distal end surfaces of the columnar parts of the other holder member. An injection needle (100A) protrudes when shortening in the axial direction has been carried out, and a perforation needle (100B) protrudes into the interior of the vial.
A forceps for an endoscope, having a blood stanching function, the forceps being capable of treatment such as blood stanching without being extracted from a forceps channel. A forceps (1) for an endoscope, comprising: a flexible elongated insertion section (10) having a double structure in a cross-section thereof and comprising a first insertion member (11) and a second insertion member (12); a pair of forceps elements (21) held at the tip of the first insertion member (11); and a ring-shaped annular member (30) which is separable by being advanced in the axial direction in response to the advance of the second insertion member (12), which faces the first insertion member (11), and then extruded to the tip side after being brought to a state in which the annular member (30) is fitted over the pair of forceps elements (21). In a state before the annular member (30) is separated, the pair of forceps elements (21) can be set only to a state in which the pair is in an incompletely closed state in which the pair can hold an organism tissue without cutting the organism tissue, while in a state in which the second insertion section (12) is advanced in the axial direction to a position at which the annular member (30) becomes separated, the pair of forceps elements (21) is in a completely closed state in which the pair can cut the organism tissue.

The invention provides a cartridge-type injection needle and injector. The injection needle cartridge has a substantially columnar retaining member for retaining the injection needle penetrating therethrough and a pair of holder members forming a containing space for containing the retaining member. The paired holding members are formed by a first holder member having a first bottom plate and a first slider section and a second holder member having a second bottom plate facing to the first bottom plate and a second slider section. The containing space is axially extendable and retractable in the state in which the slider sections are alternately displaced along the outer periphery of the retaining member and is not axially retractable in the state in which the extreme end faces of the slider sections face to each other.

Provided is an injection needle cartridge (1) comprising a needle holder (5) having an injection needle (11) held therethrough in the axial direction, a latch ring (4) for holding the needle holder (5) such that a latch portion (42) is elastically deformed to open to the radially outer circumference side, and a housing (10) for regulating the retraction of the latch ring (4) at a regulation position located on the axially forward side of an initial position and for holding the latch ring (4) and the needle holder (5) so as to regulate the relative rotation of the needle holder (5) in at least an initial position. The needle holder (5) can be moved forward, when it moves for use axially of the housing (10), while being followed by the latch ring (4), to the regulation position, and is axially extracted, when it moves back axially to the initial position, from the latch ring (4) regulated at the regulation position.
