At the tip of the syringe body 41, a discharge port 411 for discharging the chemical solution Q is formed so as to project therefrom. One end of the tube 5 is connected to the discharge port 411 in a liquid-tight manner. The tube 5 penetrates the distal end of the casing body 31 and is inserted into the casing 3 from outside to inside.

The gasket 42 is made of an elastic material such as various rubbers or thermoplastic elastomers. A pair of ring-shaped projections 421 are formed on the outer periphery of the gasket 42 at predetermined intervals. I have. When the gasket 42 moves in the axial direction of the syringe body 41, these projections 421

The pressing plate 43 has a projection 431 on the distal end side, and the projection 431 is connected to the gasket 42 by fitting into a recess formed in the gasket 42.

The coil spring 44 is stored in a compressed state.
The front end contacts the pressing plate 43, and the other end is
Is in contact with the contact plate 321. Thereby, the gasket 42 is urged in the distal direction, that is, in the direction in which the volume of the space surrounded by the syringe body 41 and the gasket 42 decreases.

The maximum capacity of the syringe pump 4 is not particularly limited, and is appropriately determined according to the type of the drug solution Q to be stored, the use form, the case, etc., but usually about 10 to 400 ml is preferable. And about 30 to 250 ml are more preferable.

It is preferable that the casing body 31 and the syringe body 41 have translucency, that is, they are transparent or translucent. Thereby, the remaining amount of the chemical solution Q can be visually recognized.

As shown in FIG. 1, a scale 36 for indicating the remaining amount of the chemical solution Q is preferably formed on the outer peripheral surface of the casing body 31 or the syringe body 41.

The chemical Q filled in the syringe pump 4 is
It is appropriately selected according to the purpose of use, and examples thereof include analgesics such as morphine (narcotic analgesic), insulin preparations, antibiotics, anticancer agents, local anesthetics, and the like. The chemical Q
The type of is not limited thereto, and includes, for example, those that do not exert a direct medicinal effect, such as physiological saline, electrolyzed water, a washing solution, an anticoagulant, and a contrast agent.

The tube 5 constitutes a conduit for supplying the chemical solution Q, and preferably has flexibility.
Examples of the constituent material of the tube 5 include various resins such as soft polyvinyl chloride, polyethylene, polypropylene, and ethylene-vinyl acetate copolymer, and various rubbers such as silicone rubber.

It should be noted that the tube 5 is not limited to a single tube, but may be a tube in which a plurality of tubes are connected. In the present specification, these are collectively referred to as "tube 5".

A flow control device 6 is provided in the middle of the tube 5. As shown in FIG.
Has a casing 61 in which a chemical solution inlet 62 and a chemical solution outlet 63 are formed. In the casing 61, an orifice 64 having a small cross-sectional area of a flow path is provided.

The chemical liquid Q flowing into the casing 61 from the chemical liquid inlet 62 receives a large pipe resistance (viscous resistance) from the pipe inner surface when passing through the orifice 64, and the flow rate is controlled to a very small amount. The flow rate in this case is not particularly limited, but is, for example, about 0.2 to 20.0 ml / hour.

As shown in FIGS. 4 and 5, the priming device 7 includes a container 8 in which a decompression chamber 80 is formed, a holder 9, and a needle tube 10.

The container 8 has a bottomed tubular tube 81 and a tubular body 8.
And a stopper 82 that hermetically shields one opening. The stopper body 82 is made of various rubber materials such as natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, butyl rubber, silicone rubber, and fluoro rubber, and various thermoplastic elastomers such as polyurethane, polyester, and polyamide. It is made of an elastic body.

The plug 82 can be pierced with a needle tube 10 described later, and preferably has a self-closing property in which the hole is closed by elasticity after the needle tube 10 is removed.

The inside of the container 8 (decompression chamber 80) is maintained in a decompressed state. The pressure in the decompression chamber 80 is not particularly limited, but is usually from 5.0 × 10 ^{−2 to} 2.0 × 10 ² torr.
About 2.0 × 10 ^{−1 to} 1.0 × 1
More preferably, it is about 0 ² torr. If the pressure in the decompression chamber 80 is too high, it may not be possible to sufficiently improve the priming speed depending on the conditions. In addition, to maintain the decompression chamber 80 at a high degree of vacuum and maintain it, This leads to increased costs.

The holder 9 is formed of a cylindrical member having an open rear end, and has a shape and dimensions that allow the container 8 to be inserted through the rear end opening.

The tip of the holder 9 has a sharp needle tip 10
1 is mounted. That is, the needle tube 10
Is fixedly supported on the hub 11, and a male screw formed on an outer peripheral portion of the hub 11 is screwed into a female screw formed on a tip end portion of the holder 9. 101 is mounted so as to be located in the holder 9. The end of the tube 5 on the downstream side of the flow control device 6 is liquid-tightly fitted to the fitting portion 111 on the distal end side of the hub 11 via the connector 12.

Around the needle tube 10, at least the needle tip 10
1 is provided. The encapsulating member 13 has a function of preventing contamination of the needle tube 10 and the like when not in use and maintaining a sterile state, and a function of preventing leakage of liquid from the needle tip 101.

The encapsulating member 13 is formed of a film made of an elastic material similar to the constituent material of the plug 82 described above, and it is particularly preferable that the encapsulating member 13 can be easily penetrated by the needle tip 101.

The end of the enclosing member 13 is fitted into the protruding portion 112 of the hub 11, and is preferably fixed by an adhesive.

In such a chemical supply device 1A, the volume of the flow path on the downstream side of the flow control device 6, more specifically,
Volume V ₁ of the portion between the orifice 64 to the connector 12 via a tube 5 is preferably 2.0 × 10 ^-3 ~5.0ml, more preferably from 0.01~0.2ml . When the volume V ₁ is too small, the present invention is not advantages sufficiently exhibited by improving priming speed by, and if the volume is too large, there is a possibility that the priming time becomes longer.

Further, the volume V ₂ of the decompression chamber 80 is not particularly limited, in relation to the volume _{V 1, 2 ≦ V 2 /} V 1
≦ 200, preferably 10 ≦ V ₂ / V ₁ ≦
It is more preferable to satisfy 50. If V ₂ / V ₁ is too small, especially when the pressure in the decompression chamber 80 is relatively high, the degree of decompression may decrease during priming and the priming speed may decrease, and V ₂ / V ₁ may be large. After that,
There is a possibility that the size of the container 8 is increased, and the operability of priming is reduced.

Next, the operation of the chemical supply device 1A at the time of priming will be described. In the drug solution storage section 2, the gasket 42 is pressed in the distal direction by the coil spring 44, and the drug solution Q filling the space surrounded by the syringe body 41 and the gasket 42 is pressurized and pushed out from the discharge port 411. Thereby, the air in the tube 5 on the upstream side of the flow control device 6 is transferred and discharged to the downstream side, and is replaced with the chemical solution Q. At this time, the discharged air passes through the orifice 64 of the flow control device 6, but the orifice 6
Since the pipeline resistance at the time of passage 4 is much smaller than that of the chemical solution Q, priming of the tube 5 upstream of the flow control device 6 is performed in a short time (for example, about several seconds to several tens of seconds).

When the liquid surface (gas / liquid separation surface) of the chemical solution Q moves downstream in the tube 5 upstream of the flow control device 6, reaches the orifice 64 of the flow control device 6, and enters there. Due to the large pipe resistance of the orifice 64, the moving speed of the liquid level decreases rapidly.

In this state, the hub 11 is connected to the connector 12 at the rear end of the tube 5, the needle tube 10 and the holder 9 are mounted, and then the container 8 is inserted into the holder 9, and the container is inserted in the distal direction (FIG. (4 in the left direction).

As a result, as shown in FIG.
Penetrates the stopper 82, and the needle tip 101 enters the decompression chamber 80. At this time, the closed end of the encapsulating member 13 is pierced through the needle tube 10, and is pressed by the end surface of the plug body 82, moved toward the hub 11, and folded in a bellows shape.

When the needle tip 101 enters the decompression chamber 80, the rear end of the tube 5 and the decompression chamber 80 communicate with each other via the needle tube 10 or the like.
The air inside each of the tubes 5 on the downstream side from the hub 11, the connector 11, and the flow control device 6 is sucked to be in a reduced pressure state.

The liquid surface of the chemical solution Q that has reached the orifice 64 is suctioned in the downstream direction because the downstream side thereof is in a reduced pressure state, and moves at a higher speed. The speed at which the chemical solution Q flows through the orifice 64 is, for example, about two to three times the former in the case where the downstream side of the orifice 64 is depressurized and in the conventional case where the pressure is not depressurized.

After passing through the orifice 64, the liquid surface moves further inside the tube 5 downstream of the orifice 64,
This part is primed by the chemical solution Q. Also at this time, the moving speed (priming speed) of the liquid surface to the downstream side is increased by the depressurizing action as described above.

When the chemical solution Q flows out of the needle tip 101 of the needle tube 10, it is considered that the priming has been completed, and the container 8 is removed from the holder. As a result, the needle tube 10 is
Removed from 2. When the needle tube 10 is withdrawn from the plug 82, at the same time, the envelope member 1 folded in a bellows shape
3 instantaneously restores its original shape by its elastic force.
Since the needle tube 10 is encapsulated again as shown in FIG.
1 prevents the chemical solution Q from leaking and scattering around.

The chemical Q flowing out of the needle tip 101 is
Since the drug solution Q is collected in the container 8, it is prevented from being scattered around. Even when the drug solution Q requires strict management like a drug preparation, the drug solution Q flowing out of the needle point 101 is not removed. Since it is collected in the container 8, its management becomes easy.

When the priming with the chemical solution Q is completed as described above, the connector 12 is detached from the hub 11 and the hub of the indwelling needle for puncturing a blood vessel or the like of the patient or the end of the tube connected to the indwelling needle ( (Not shown), and after priming the inside of the tube with a chemical solution Q, the middle of the tube 5 is temporarily closed with creme or the like (not shown).

After puncturing the indwelling needle into a blood vessel or the like of a patient,
The blockage of the tube 5 by the clamp is released. As a result, a small amount of the drug solution Q is injected and administered to the patient at a slow injection speed controlled by the orifice 64 of the flow control device 6.

Instead of the indwelling needle, a puncture needle such as a bottle needle is connected to the connector 12, and the puncture needle is punctured and communicated with another container such as an infusion bag or a blood bag, and the drug solution is inserted into the container. Q can be supplied (blended).

In the above embodiment, the needle tube 10 and the indwelling needle for puncturing the patient (or the bottle needle for puncturing bags etc.)
The indwelling needle (or bottle needle or the like) is attached to the rear end of the tube 5 from the beginning, and the indwelling needle is punctured into the stopper 82 of the container 8 to obtain a reduced pressure state. Priming may be performed. In this case, priming and drug solution administration (chemical solution injection) can be performed without replacing the needle, and operability and sterility are further improved.

The communication between the flow path on the downstream side of the orifice 64 and the inside of the container 8 is not limited to the above-described piercing of the plug 82 with the needle tube 10. Chamber) and a flow path downstream of the orifice 64 are cut off by a breakable member, and are configured to break when used (during priming) to communicate with each other, or a flow path such as a cock Any member such as a switching member may be used.

The balloon 45 is a bag made of various rubber materials (elastic materials) such as, for example, silicone rubber, natural rubber and isoprene rubber. The liquid medicine Q filled in the balloon 45 is pressurized by the contraction force of the balloon 45, discharged from the mouth 46, and transferred to the downstream side via the tube 5.

The maximum capacity of the balloon 45 is not particularly limited, and is appropriately determined according to the type of the drug solution Q to be stored, the form of use, the case, and the like. Usually, it is preferably about 30 to 400 ml. A volume of about 50 to 250 ml is more preferable.
