Abstract

A pattern (131) consisting of lines (132B, 132Y) are indicated on a U-shaped concave surface (121) for holding a cylinder member (210) of a chemical liquid syringe (200), and when viewed from above, the lines (132B, 132Y) intersect with each other in an X-shape near the center in the right/left direction. When the cylinder member (210) held in the concave surface (121) is filled with air (A), the lines (132B, 132Y) of the pattern (131) intersecting in the X-shape are visible. When it is filled with chemical liquid (L), the pattern (131) becomes a pseudo-stripe pattern. The pattern (131) visible when the chemical syringe (200) is filled with chemical liquid and the pattern visible when it is filled with air are significantly different from each other, so that a medical error such as air being injected into a subject can be excellently prevented.

[0006] In a general syringe drive device, a concave portion having a shape corresponding to the cylinder member and the cylinder flange of the chemical syringe is formed on the upper surface of the injection execution head. Therefore, the cylinder member and the cylinder flange are loaded into the concave portion. If you do The syringe is held.

[0007] Further, the syringe drive device holds the piston flange separately from the cylinder member by the biston drive mechanism, and slides the biston member by the biston drive mechanism. Thus, the chemical solution can be injected into the subject from the chemical solution syringe, and if necessary, the chemical solution can be inhaled from the chemical solution tank to the chemical solution syringe.

[0008] However, since the syringe drive device as described above generally mounts a plurality of types of chemical liquid syringes of various shapes, the recess of the injection execution head corresponds to the cylinder member of the maximum size chemical liquid syringe.

[0009] Such a cylinder adapter also has a recess formed on the top surface corresponding to a cylinder member and a cylinder flange that are generally mounted in the same manner as the injection execution head. The member and cylinder flange are held. The bottom surface of the cylinder adapter is formed in the same shape as the cylinder member and cylinder flange of the maximum size chemical syringe, and is loaded into the recess of the injection head.

[0010] It should be noted that the syringe drive device as described above has been invented and filed in the past by the applicant of the present application (see, for example, Patent Documents 1 and 2). Further, the present applicant has also proposed a syringe drive device that injects a chemical solution into a chemical solution syringe by retracting a biston member from a cylinder member connected to the chemical solution container (see, for example, Patent Document 3).

But such a cylinder member The chemical solution such as physiological saline or contrast medium filled in the container may be colorless and transparent.

[0012] In such a case, the filling of the chemical solution is confirmed by refraction adjustment of the scenery visually recognized through the cylinder member, but it is inadvertently determined that the chemical syringe that is not filled with the chemical solution is filled. May be.

[0013] In this case, a liquid syringe filled with air is loaded into the syringe drive device and connected to the blood vessel of the subject, which causes a medical accident in which air is injected into the blood vessel of the subject.

[0016] Therefore, in the syringe drive system of the present invention, when a chemical syringe filled with air instead of a chemical solution is loaded on the concave surface of the syringe holding mechanism of the syringe drive device, the design is optically generated by the chemical syringe. Because it is not refracted, multiple line segments that intersect the X shape of the design are visible. On the other hand, when a chemical syringe filled with a chemical solution is loaded on the concave surface of the syringe holding mechanism of the syringe drive device, the design is optically refracted by the chemical syringe. In that case, the chemical syringe filled with the chemical functions as a cylindrical lens. It is visually recognized in a state where the central portion in the left-right direction is expanded in the left-right direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as being greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern.

[0018] Therefore, in the syringe drive system of the present invention, when the chemical syringe filled with air instead of the chemical solution is loaded on the concave surface of the cylinder adapter, the design is not optically refracted by the chemical syringe. Multiple line segments intersecting the X shape of the design are visible. On the other hand, when a chemical syringe filled with a chemical solution is loaded on the concave surface of the cylinder adapter, the design is optically refracted by the chemical syringe. In that case, the liquid syringe filled with the liquid chemical functions as a cylindrical lens, and the center part in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as being greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a stripe-like pattern.

[0019] A third syringe drive system of the present invention includes a chemical liquid syringe, a syringe drive device, and a syringe cover, and the chemical liquid syringe is a transparent container that contains a transparent chemical liquid. A cylinder member and a piston member slidably inserted into the cylinder member, and the syringe cover has a defined lower surface position, and the axial direction is from the rear in the front-rear direction. The syringe drive device is formed in a transparent cylindrical shape that holds the cylinder member of the chemical syringe to be inserted. The syringe drive device has a syringe holding mechanism that holds the cylinder member of the chemical syringe by the syringe cover, and the chemical syringe is held. A syringe drive system that moves the piston member relative to the cylinder member in the front-rear direction, and the syringe cover intersects in an X shape near the center in the left-right direction when viewed from above A symbol composed of a plurality of line segments is written on the lower surface.

[0020] Therefore, in the syringe drive system of the present invention, when a chemical syringe filled with air instead of a chemical solution is loaded inside the syringe cover, the design is not optically refracted by the chemical syringe. Multiple line segments intersecting in an X shape are visible. On the other hand, when a chemical syringe filled with a chemical solution is loaded inside the syringe cover, the design is optically refracted by the chemical syringe. In that case, the chemical syringe filled with the chemical solution functions as a cylindrical lens, and the central portion in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern.

[0021] A fourth syringe drive system of the present invention includes a chemical syringe and a syringe drive device, and the chemical syringe has a transparent cylinder member that has a position on the lower surface and contains a transparent chemical solution.

When viewed from above without being contained, X-shaped near the center in the left-right direction A pattern composed of a plurality of intersecting line segments is written on the lower surface of the cylinder member.

[0022] Therefore, in the syringe drive system of the present invention, when the chemical syringe is filled with air instead of the chemical solution, the pattern is not optically refracted by the chemical syringe, and thus intersects the X shape of the pattern. Multiple line segments are visible. On the other hand, when the chemical syringe is filled with a chemical solution, the design is optically refracted by the chemical syringe. In that case, the chemical syringe filled with the chemical solution functions as a cylindrical lens, and the central portion in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern.

[0023] The syringe drive device of the present invention is a syringe drive device that drives a chemical solution syringe having a structure in which a biston member is slidably inserted into a transparent cylinder member that contains a transparent chemical solution, and the axial direction of the syringe drive device is The cylinder holding mechanism that holds the cylinder member of the chemical syringe mounted from above in the front-rear direction with a concave surface curved in a U shape, and the biston member relative to the cylinder member that holds the chemical syringe in the front-rear direction A piston drive mechanism to be moved, and a pattern composed of a plurality of line segments intersecting in an X shape near the center in the left-right direction when viewed from above is shown on the concave surface.

Therefore, in the syringe drive device of the present invention, when a chemical syringe filled with air instead of a chemical solution is loaded on the concave surface of the syringe holding mechanism, the pattern is not optically refracted by the chemical syringe. Multiple line segments intersecting the X shape of the design are visible. On the other hand, when a chemical syringe filled with a chemical solution is filled in the concave surface of the syringe holding mechanism, the design is optically refracted by the chemical syringe. In that case, the liquid syringe filled with the liquid chemical functions as a cylindrical lens, and the central portion in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as being greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern. [0025] The cylinder adapter of the present invention is a cylinder adapter for adapting a chemical syringe having a structure in which a biston member is slidably inserted into a transparent cylinder member containing a transparent chemical solution to a syringe drive device. A U-shaped curved concave surface is formed to hold the cylinder member of the chemical syringe mounted from above with the axial direction in the front-rear direction. When viewed from above, the X is near the center in the left-right direction. A pattern consisting of a plurality of line segments intersecting in a pattern is written on the concave surface.

[0026] Therefore, in the cylinder adapter of the present invention, when a chemical syringe whose air is filled in the concave surface instead of the chemical solution is loaded, the design is not optically refracted by the chemical syringe. A plurality of intersecting line segments are visually recognized. On the other hand, when a chemical syringe having a concave surface filled with a chemical solution is loaded, the pattern is optically refracted by the chemical solution syringe. In that case, the liquid syringe filled with the liquid chemical functions as a cylindrical lens, and the central portion in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as being greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern.

[0027] A syringe cover according to the present invention is a syringe cover for holding a syringe drive device having a structure in which a viston member is slidably inserted into a transparent cylinder member that contains a transparent drug solution. The position to be the lower surface is defined, and it is formed in a transparent cylindrical shape that holds the cylinder member of the chemical syringe inserted from the rear with the axial center direction being the front-rear direction, and was seen from above Sometimes a symbol consisting of multiple line segments intersecting in an X shape near the center in the left-right direction is shown on the bottom.

A plurality of intersecting line segments are visually recognized. On the other hand, when a chemical syringe filled with a chemical solution is loaded, the pattern is optically refracted by the chemical syringe. In that case, the medicine is filled The chemical syringe functions as a cylindrical lens and is visually recognized with the central part in the left-right direction of the design expanded in the left-right direction. In that case, multiple line segments

[0029] The chemical syringe of the present invention is a chemical syringe driven by a syringe drive device in a structure in which a piston member is slidably inserted into a transparent cylinder member that contains a transparent chemical solution, and is axially oriented. The position of the bottom surface is defined in the cylinder member with the front-rear direction, and there are multiple lines that intersect in the X shape near the center in the left-right direction when viewed from above without containing chemicals A divided symbol is printed on the bottom surface of the cylinder member.

[0030] Therefore, in the chemical syringe of the present invention, when the cylinder member is filled with air instead of the chemical solution, the design is not optically refracted by the cylinder member, and therefore a plurality of lines intersecting the X shape of the design. Minutes are visible. On the other hand, when the cylinder member is filled with a chemical solution, the design is optically refracted by the cylinder member. In this case, the cylinder member filled with the chemical solution functions as a cylindrical lens, and is visually recognized in a state where the central portion in the left-right direction of the design is expanded in the left-right direction. In that case, since the angle of the X-shaped intersections of the plurality of line segments is visually recognized as greatly reduced in the front-rear direction, for example, the plurality of line segments are visually recognized as a striped pattern.

In the figure, a pattern consisting of multiple line segments intersecting in an X shape near the center in the left-right direction is shown on the back.

[0032] Therefore, in the chemical solution container of the present invention, when the air is filled instead of the chemical solution, the design is not optically refracted, so that a plurality of line segments intersecting the X shape of the design are visible. On the other hand, when the chemical is filled, the pattern is optically refracted. In that case, the chemical solution container filled with the chemical solution functions as a cylindrical lens, and is visually recognized in a state where the central portion in the horizontal direction of the pattern is expanded in the horizontal direction. In that case, since the angle of the X-shaped intersections of the multiple line segments is visually recognized as greatly reduced in the diameter direction of the chemical solution container, for example, the multiple line segments are visually recognized as striped patterns. The

[0033] The container support device of the present invention is a container support device that holds a transparent cylindrical chemical solution container that contains a transparent chemical solution, and holds the chemical solution container in a state where the axial direction is the vertical direction. A concave surface curved in a U-shape is formed as the front surface, and a pattern consisting of a plurality of line segments intersecting in an X-shape near the center in the left-right direction when viewed from the front is shown on the concave surface.

[0034] Therefore, in the container support device of the present invention, when a chemical liquid container having a concave surface filled with air instead of a chemical liquid is placed, the pattern is not optically refracted by the chemical liquid container. A plurality of line segments intersecting in a shape are visually recognized. On the other hand, when a chemical container filled with a chemical solution is disposed on the concave surface, the pattern is optically refracted by the chemical solution container. In that case, the chemical container filled with the chemical functions as a cylindrical lens, and the central part in the horizontal direction of the design is visually recognized in a state of being expanded in the horizontal direction. In that case, since the angle of the X-shaped intersection of the plurality of line segments is visually recognized as being greatly reduced in the vertical direction, for example, the plurality of line segments are visually recognized as a stripe-like pattern.

[0035] In the present invention, the front-rear, left-right, up-down, and up-down directions are defined, but this is defined for convenience in order to briefly explain the relative relationship of the components of the present invention. The direction at the time of manufacture and use is not limited. The invention's effect

[0063] In the configuration as described above, when using the fluoroscopic imaging system 100 according to the present embodiment, for example, the operator can use the fluoroscopic imaging unit 30 of the MRI apparatus 300.

The chemical solution syringe 20 0 0 is connected to the blood vessel of the subject located at 1 by an extension tube (not shown), and the chemical solution syringe 2 0 0 is connected to the injection execution head of the chemical solution injection device 1 0 0.

Load 1 1 0.

In this case, as shown in FIG. 2, the opening and closing flange holding mechanism 1 2 2 of the injection execution head 1 1 0 is opened, and the cylinder flange 2 1 3 is inserted there. The member 2 1 0 is inserted into the concave surface 1 2 1 from above.

At this time, as shown in FIG. 6 (a), the cylinder flange 2 13 is inserted into the cylinder holding mechanism 120 from above with the flat portions 2 14 positioned on the left and right. Next, as shown in FIG. 6 (b), in a state where the cylinder body 2 11 is in contact with the concave surface 1 2 1, the cylinder member 2 1 0 is rotated until the position of the lower surface is lowered. Moved.

Then, as shown in FIG. 6 (c), the elastic arms 1 2 3 are elastically engaged with the concave grooves 2 15 at the left and right ends of the cylinder flange 2 1 3. Then, as shown in FIG. 5 (b), when the flange holding mechanism 1 2 2 is closed, the chemical syringe 2 200 is held in an appropriate state by the flange holding mechanism 1 2 2 and the resilient arm 1 2 3. The

[0067] Here, the flange holding mechanism 1 after the chemical syringe 200 is rotated.

Although the example of closing 2 2 is illustrated, the chemical syringe 200 may be rotated after the flange holding mechanism 1 2 2 is closed.

[0068] In the state as described above, the operator performs the injection control unit 1 of the chemical injection device 1 0 0.

0 Operate 1 manually. Then, the chemical injection device 1 0

0 piston drive mechanism 1 1 4 operates.

Therefore, the screw drive mechanism 1 1 4 presses the screw member 2 2 0 of the chemical syringe 2 200 into the cylinder member 2 1 0, and the cylinder member 2 1 0 gives a contrast agent to the subject. The chemical solution L is injected. Then, a fluoroscopic image is taken by the MRI apparatus 300 from the subject into which the medicinal solution L is injected.

[0070] The chemical solution injection device 100 according to the present embodiment press-fits the piston member 220 into the cylinder member 210 of the chemical syringe 20 filled with the chemical solution L as described above. Inject drug solution L into the subject.

[0071] However, if a chemical syringe 200 that is filled with air A instead of chemical L is used, such as once used, a medical error will occur in which air A is injected into the blood vessel of the subject. It will be.

[0072] In particular, when the drug solution L is injected into the subject as described above, the operator manually operates the injection control unit 1 0 1, so that the injection execution head in which the drug solution syringe 2 0 0 is loaded is used. 1 1 Separated from 0.

However, in the fluoroscopic imaging system 1 0 0 0 of the present embodiment, the injection execution head

The 1 1 0 concave surface 1 2 1 is marked with the symbol 1 3 1. And the chemical syringe

If 2 0 0 is filled with air instead of a chemical solution, the chemical solution syringe 2 0 0 The symbol 1 3 1 is not optically refracted.

[0074] For this reason, as shown in Fig. 1 (a), a plurality of line segments 1 3 2 B, 1 3 2 Y intersecting in the X shape at the center of the left and right and intersecting in the V shape at the left and right outer edges Visible as 1. In this state, the line segments 1 3 2 B and 1 3 2 Y are evenly positioned in the front, back, left and right in the entire area of the pattern 1 3 1, so that the pattern 1 3 1 is visually recognized as a mesh pattern.

On the other hand, when the chemical solution syringe 200 is filled with a chemical solution, and when the chemical solution syringe 200 is filled with a chemical solution, the pattern 1 3 1 is optically refracted by the chemical solution syringe 200. The In this case, the chemical solution syringe 200 filled with the chemical solution functions as a cylindrical lens, and is visually recognized in a state where the central portion in the left-right direction of the symbol 13 1 is expanded in the left-right direction.

For this reason, as shown in FIG. 1 (b), the symbol 13 1 is visually recognized in a plurality of parallel line segments spaced in the front-rear direction. In this state, lines 1 3 2 B and 1 3 2 Y are concentrated and non-concentrated in the pattern 1 3 1 area alternately in the front-rear direction. Visible as a pattern.

In the fluoroscopic imaging system 10 00 of the present embodiment, in the state where the drug solution syringe 200 is loaded in the drug solution injection apparatus 100 as described above, the drug solution L is stored in the drug solution syringe 200. The symbol 1 3 1 that is visible when the air is filled and the air A is filled is significantly different.

Therefore, for example, it is possible to easily and reliably prevent a medical mistake in which air is injected into a subject by driving the chemical syringe 200 filled with air with the chemical injection device 100.

[0079] Further, as shown in FIG. 7, the symbol 1 3 1 is composed of a plurality of line segments 1 3 2 B and 1 3 2 Y that are sinusoidal in a flatly developed state. ) As shown in the figure, the V-shaped intersection near the left and right outer edges of line segments 1 3 2 B and 1 3 2 Y is the inner part of the X-shaped intersection.

[0080] For this reason, when the chemical syringe 2 0 0 filled with the chemical solution L and loaded into the chemical solution injector 100 is viewed from an oblique direction, the line segment 1 3 2 B, 1 of the pattern 1 3 1 3 2 Y is visually recognized as spirally written on the peripheral surface of the cylinder member 2 1 0 The

[0081] For this reason, even when the chemical solution syringe 200 loaded in the chemical solution injection device 100 is viewed from a direction other than the upper side, the chemical solution syringe L 200 is filled with the chemical solution L or air A It is possible to check easily and surely whether or not is filled.

[0082] Moreover, the pattern 1 3 1 of the present embodiment is a line segment of color development having yellow as a main component.

It consists of 1 3 2 Y and colored line segment 1 3 2 B with blue as the main component. Therefore, 1 3 2 B, 1 3 2 Y consists of two types, light and dark, two types, warm and cold, and two types, expansion and contraction, and forward color It consists of two types of color and reverse color, and has two types of complementary colors.

In other words, the line segments 1 3 2 B and 1 3 2 Y of the pattern 1 3 1 have contradictory visual characteristics. For this reason, for example, even if the visibility of one of the line segments 1 3 2 B and 1 3 2 Y decreases due to the relationship with the liquid color L cylinder member 2 10 and the color of lighting, the other visibility Will improve.

[0084] Accordingly, even when the chemical liquid L cylinder member 210 or lighting or the like generates a unique color, it is determined whether the chemical liquid syringe 200 is filled with the chemical liquid L or air A. It can be confirmed well.

In addition, in the symbol 1 3 1 according to the present embodiment, the yellow line segment 1 3 2 Y is narrow and the blue line segment 1 3 2 B is wide. For this reason, the visibility of the blue line segment 1 3 2 B is generally lower than that of the yellow line segment 1 3 2 Y, but the visibility of these line segments 1 3 2 B and 1 3 2 Y is equivalent. It can be. Therefore, it can be confirmed well in both of the two types of line segments 1 3 2 B and 1 3 2 Y whether the chemical liquid syringe 200 is filled with the chemical liquid L or the air A.

[0086] Further, in the fluoroscopic imaging system 100 according to the present embodiment, the symbol 1 31 is written on the adhesive seal 1 30 and this adhesive seal 1 3 0 is the chemical solution injection device 1 0 0. It is attached to the concave surface 1 2 1.

For this reason, the pattern 1 3 1 can be easily formed on the curved concave surface 1 2 1 where it is difficult to form the line segments 1 3 2 B and 1 3 2 Y by printing. In addition, existing drugs The design 1 3 1 can be easily formed on the concave surface 1 2 1 simply by sticking the adhesive seal 1 3 0 to the liquid injection device 1 0 0.

[0088] Therefore, an adhesive seal 1 3 0 is distributed as a after-sales service to the chemical injection device 1 0 0 that has already been shipped to the end user for a fee or free of charge, and the pattern 1 3 1 on the concave surface 1 2 1 Can also be formed.

The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the spirit of the present invention. For example, in this embodiment, the chemical solution syringe 20

MR contrast medium is filled in as 0 as chemical liquid L, and chemical injection device 1 0 0

It was assumed that it would be used in the vicinity of the MRI apparatus 300.

[0090] However, a contrast solution for CT or ultrasonic diagnosis is added to the drug solution syringe 200.

It is filled as L, and the chemical solution injection device 100 may be used in the vicinity of the CT scanner which is a fluoroscopic imaging device (not shown).

[0091] Further, in the above embodiment, it is exemplified that the adhesive seal 1 3 0 on which the symbol 1 3 1 is written is attached to the chemical solution injector 100. However, chemical injection device 1

The pattern 1 3 1 may be directly formed on the 0 0 concave surface 1 2 1 by printing or the like.

[0092] Further, in the above embodiment, in order to simplify the explanation, it is exemplified that a kind of chemical solution syringe 200 of the chemical solution injection device 100 is loaded, but actually, the chemical solution injection device 100 is In general, a plurality of types of chemical syringes 200 are loaded.

[0093] In addition, a chemical injection device in which two types of chemical syringes 20 each filled with a contrast medium and physiological saline as the chemical L is simultaneously mounted in parallel is also common. Therefore, such a syringe drive system 120 will be briefly described below with reference to FIG.

In this syringe drive system 1 2 0 0, a cylinder holding mechanism 1 2 0 and a piston drive mechanism 1 1 4 are formed in two parallel rows on the chemical liquid injector 4 0 0. In addition, there are a plurality of sizes as the chemical solution syringe 200, and only the maximum size chemical solution syringe 200 is directly loaded into the chemical solution injection device 400.

[0095] For this reason, the cylinder adapter is not to be changed every 2 0 0. 4 1 0 is provided. As described above, the chemical solution injector 400 directly holds the maximum size chemical syringe 20 0 by the cylinder holding mechanism 120, but the non-maximum size chemical syringe 20 0 0 is a cylinder adapter. Hold through 4 1 0.

Note that the cylinder adapter 4 1 0 also has a cylinder holding mechanism (not shown) similar to that of the chemical solution injector 100, and the U-shaped curved concave surface 4 1 1 makes the chemical solution syringe 2 0 0 cylinder member 2 1 0 is held.

Therefore, in the syringe drive system 1 2 0 0 exemplified here, the symbol 1 3 1 is written on the concave surface 4 1 1 of the cylinder adapter 4 1 0. For this reason, even if a chemical liquid syringe 200 having a size other than the maximum is loaded into the chemical liquid injector 400 through the cylinder adapter 4 10, the chemical liquid syringe 200 is filled with the chemical liquid L or air. It is possible to check well whether the A is filled with the pattern 1 3 1 of the cylinder adapter 4 10.

[0098] It should be noted that this pattern 1 3 1 may be formed on the inner surface, the outer surface or the inner surface as long as the cylinder adapter 4 10 is sufficiently transparent. However, if the cylinder adapter 4 10 is translucent or opaque, it is natural that the pattern 1 3 1 is formed on the inner surface. Further, even in the above-described chemical liquid injector 400, the maximum size chemical liquid syringe 200 is directly loaded, and therefore it is preferable that the symbol 13 1 is written on the concave surface 1 2 1.

Further, as shown in FIG. 10, a syringe drive system 1 3 0 0 in which the chemical syringe 2 200 is inserted into the cylindrical transparent syringe cover 5 1 0 and loaded into the chemical injection device 5 0 0. There is also. Therefore, in such a syringe drive system 1 3 0 0, it is preferable that the design 1 3 1 is formed on the lower surface of the syringe cover 5 1 0.

[0100] As described above, the cylinder adapter 4 1 0 or the syringe cover 5 1 0 may be used as a method of forming the pattern 1 3 1 on the concave surface 4 1 1 of the cylinder adapter 4 1 0 or the lower surface of the syringe cover 5 1 0. If is sufficiently transparent, the pattern 1 3 1 may be formed not on the inside but on the outside or inside. In other words, cylinder adapter 4 1 0 If the syringe cover 5 1 0 is translucent or opaque, the pattern 1 3

1 should be formed.

[0101] It should be noted that the current general chemical syringe 200 has an upper surface and a lower surface defined as described above, and a pair of flat portions on the cylinder flange 2 1 3 corresponding to the upper surface and the lower surface. 2 1 4 is formed.

[0102] For this reason, as shown in FIG. 5 (a), when the drug solution syringe 200 is loaded into the drug solution injection device 100 with its upper and lower positions positioned on the left and right sides, the flange holding mechanism

The area of the cylinder flange 2 1 3 held by 1 2 2 is insufficient.

In this case, the cylinder flange 2 1 3 may be broken and the cylinder member 2 1 0 may be ruptured by the pressure at which the piston member 2 2 0 is press-fitted. Therefore, if this becomes a problem, it is better to mark the symbol 1 3 1 on the lower surface of the chemical syringe 4 20 as shown in FIG.

[0104] In this case, only when the chemical syringe 20 is filled with the chemical L and the chemical syringe 4 20 is loaded in the proper direction into the chemical injection device 100

As shown in 1 (b), the symbol 1 3 1 is visually recognized as a pseudo-striped pattern.

That is, both of the fact that the chemical liquid L is filled in the chemical syringe 4 20 and that the chemical syringe 4 2 0 is loaded in the appropriate direction in the chemical injection device 1 0 0 at a glance. It can be confirmed easily and reliably.

[0106] In the above embodiment, it is assumed that the cylinder member 210 of the chemical syringe 20 has good translucency in the entire circumferential direction. However, as shown in Figure 1 1 (a)

Oxygen parts 2 3 on the left and right of the outer peripheral surface of the cylinder member 2 10 0

0 may be formed.

Similarly, as shown in FIG. 11 (b), the cylinder member 2 of the chemical syringe 2 0 0

The entire outer peripheral surface of 10 may be the opaque portion 2 3 1, and the translucent window portion 2 3 2 may be formed only above and below the opaque portion 2 3 1.

In this case, as shown in FIG. 5 (a), when the chemical syringe 2 0 0 is loaded in the chemical injection device 1 0 0 in an inappropriate direction, the concave surface 1 2 1 of the chemical injection device 1 0 0 The pattern 1 3 1 is shielded by the opaque parts 2 3 0 and 2 3 1 of the chemical syringe 2 0 0. On the other hand, when the chemical solution syringe 200 is loaded into the chemical solution injection device 100 in an appropriate direction, the pattern 131 of the chemical solution injection device 100 is visually recognized through the chemical solution syringe 200. For this reason, it is easy to confirm at a glance both the fact that the chemical syringe 200 is filled with the chemical solution L and the chemical solution injection device 100 is loaded in the proper direction at a glance. be able to.

[0110] As described above, when sticking the adhesive seal 130 to the chemical syringe 420 to the cylinder adapter 41 0 to the syringe cover 510, an RF ID chip may be mounted on the adhesive seal 1 30 (Fig. Not shown).

[0111] In this case, various data such as the chemical solution L can be registered in the RF ID chip. In addition, since the RF ID chip is also mounted by sticking the sticker seal 1 30 of the pattern 1 31 to the chemical syringe 420, the RF ID chip can be easily mounted on the chemical syringe 420 or the like.

[0112] When an RF ID chip is mounted on the chemical syringe 420 or the like as described above, an RF ID reader that reads various data from the RF ID chip may be mounted on the chemical liquid injector.

[0113] As described above, a syringe drive system in which an RF ID chip is mounted on a chemical syringe or the like and an RF ID reader is mounted on a chemical liquid injection device has been disclosed in Japanese Patent Application No. 2004-059034 and Japanese Patent Application No. 2004-207345. No., Japanese Patent Application No. 2 004-327479, Japanese Patent Application No. 2004-334942, Japanese Patent Application No. 2004-345493, Japanese Patent Application No. 2005-1 1 3065, etc.

[0114] Further, in the above embodiment, the chemical liquid injection device 100 that press-fits the piston member 220 into the cylinder member 210 of the chemical liquid syringe 200 is exemplified as the syringe driving device. However, as such a syringe drive device, a chemical solution inhaler (as illustrated) that retracts the piston member 220 from the cylinder member 210 of the chemical solution syringe 200 connected to the chemical solution container and sucks the chemical solution L from the chemical solution container into the chemical solution syringe 200. Without).

[0115] Further, in the above embodiment, the case where the chemical syringe 200 loaded in the chemical injector 100 is viewed from above is exemplified. However, a transparent chemical solution In a container support device that holds a clear cylindrical chemical solution container, a U-shaped concave surface 1 2 1 is formed to hold the chemical solution container in a state where the axial center direction is upward and downward, and the concave surface 1 2 Symbol 1 3 1 may be written on 1 (not shown).

[01 16] In this case, when the chemical container held from the rear by the concave surface 1 2 1 of the container receiver is viewed from the front, the chemical container is filled with the chemical L or air.

Check if A is filled.

[01 17] When the front-rear direction is defined in the chemical container as described above, the symbol 13 1 may be written on the rear surface (not shown). In this case as well, when the chemical container is viewed from the front, it is confirmed whether the chemical liquid L is filled or air A is filled.

[0118] Further, in the above embodiment, it is exemplified that the symbol 1 3 1 is represented by a predetermined colored line segment 1 3 2. However, for example, the pattern 1 31 may be formed of a paint that produces a predetermined color at a predetermined temperature.

[01 19] In general, a chemical solution L such as a contrast medium to be injected in a large amount into a subject is required to be heated in advance to a temperature similar to the body temperature. Therefore, for example, if the pattern 1 3 1 is formed with a paint that is colored only when the chemical liquid is at an appropriate temperature and is colorless when the temperature is not appropriate, the temperature of the chemical liquid L due to the coloring of the pattern 1 3 1 It is possible to confirm whether it is appropriate.

[0120] Further, in the above embodiment, the line segment 1 3 2 of the pattern 1 3 1 is illustrated as a sine wave. However, the line segment may be formed in a hyperbola shape, may be formed by a combination of parabolas, or may be formed by an arbitrary free curve.

[0121] Furthermore, in the above embodiment, the pattern 1 3 1 is illustrated as being formed of continuous and smooth line segments 1 3 2. However, the pattern may be formed by so-called dotted lines or wavy lines. As a matter of course, various modifications described above can be combined in various ways as long as the contents do not conflict with each other.
