Description

  The present invention relates to a blood collection tube stamp for marking an upper surface of a cap in a blood collection tube.

  When a blood collection tube is handled in a hospital or clinical laboratory center, a mark 91 is applied to the cap 90 of the blood collection tube 9 as shown in FIGS. 16 (a) and 16 (b). This is for distinguishing the types of specimens contained in the blood collection tubes (for example, infected specimens, emergency specimens, normal specimens, dock specimens, or hospital specimens).

  The mark 91 of the cap 90 is given by, for example, an inspection engineer or a nurse using a writing instrument such as a magic or a pen. Such a method is an inefficient operation when handling many specimens because it is necessary to repeatedly attach and detach the cap of the writing instrument. On the other hand, if the writing instrument lid is removed and left unattended, the case for storing the writing instrument and the user's hand may become dirty, and the evaporation of the ink will be promoted.

  A central portion 93 of the upper surface 92 of the cap 90 in the blood collection tube is usually a portion into which a blood collection needle or a sample suction nozzle of an analyzer is inserted. Therefore, as shown in FIG. 16B, when the center portion 93 of the upper surface 92 of the cap 90 is marked with a magic or the like, the sample aspirating nozzle becomes dirty or ink such as magic enters the sample. There is a possibility that. The contamination of the sample suction nozzle and the mixing of ink into the sample may cause a measurement error or cause a measurement error.

  On the other hand, instead of applying the mark 91 to the cap 90 with a writing instrument, an apparatus that prints predetermined information on the side surface of the blood collection tube 9 using an ink jet printing apparatus has also been proposed (see, for example, Patent Document 1).

  However, since the inkjet printing apparatus is expensive and relatively large, the use of the printing apparatus not only causes an increase in inspection cost but also presses the inspection space.

  In addition, in an inkjet printing apparatus, information to be printed on the blood collection tube needs to be input to the apparatus, which increases the burden on the person inspected, and is an unsuitable method in an emergency.

Japanese Patent No. 2753729

  An object of the present invention is to make it possible to appropriately inspect a sample by suppressing contamination of the sample suction nozzle and mixing of ink into the sample while allowing the blood collection tube to be marked inexpensively and easily. .

The present invention provides a blood collection tube stamp for marking an upper surface of a cap in a blood collection tube, and has a marking surface for contacting the cap, and one or a plurality of ink holding portions holding ink. The present invention relates to a blood collection tube stamp comprising: a holder that houses the ink holding portion; and a pressing body that is provided at the center of the holder and is connected to the holder and presses the upper surface of the cap.

  The ink holding portion is formed so that the marking surface is brought into contact with a peripheral region of the central portion on the upper surface.

  The ink holding portion may be formed so that the marking surface is brought into contact with a peripheral region of the needle insertion portion for inserting the blood collection needle on the upper surface.

  The marking surface is formed in an arc shape, for example. The marking surface may be linear or annular.

  The blood collection tube stamp of the present invention further includes, for example, one or more operation units for moving the ink holding unit relative to the holder.

  The operation unit covers, for example, at least a part of the holder and is connected to the ink holding unit.

  The plurality of operation units may support the ink holding unit and be movable relative to the holder independently of each other.

  The blood collection tube stamp of the present invention may be provided with a plurality of movable bodies that are movable relative to the holder in the vertical direction and are brought into contact with the cap. In this case, each of the plurality of ink holding portions is configured to move downward relative to the holder when the corresponding movable body moves upward relative to the holder. Is preferred. Each of the plurality of ink holding units is configured to move in conjunction with the movement of the movable body at the most distant position among the plurality of movable bodies, for example.

  The plurality of movable bodies may be configured such that the relative positions with respect to the holder can be adjusted.

Upper Symbol pressing body is connected to the holder via the elastic body.

  The holder may have a guide for covering the cap. The guide has, for example, a tapered shape whose diameter increases toward the lower side.

  The holder may have an opening for projecting the ink holding portion and an open / close lid that closes the opening in a state where the ink holding portion does not protrude from the opening.

Hereinafter, a stamp for blood collection according to the present invention will be described in detail with reference to the drawings as a reference example and first and second embodiments .

First, a blood collection stamp according to a reference example of the present invention will be described with reference to FIGS. In these drawings, the center of the cap 20 of the blood collection tube 2 will be described as an example where the central portion of the cap 20 of the blood collection tube 2 is formed in a convex shape into which a sample aspirating nozzle in the analyzer is inserted.

  The blood collection tube stamp 1 shown in FIGS. 1 to 3 is for marking the upper surface 21 of the cap 20 of the blood collection tube 2.

  The blood collection tube stamp 1 includes a pair of ink holding units 10, a holder 11, and an operation unit 12.

  The ink holding unit 10 holds ink to be attached to the upper surface 21 of the cap 20 and has a circular arc shape with a uniform cross section. The radius of curvature of the cross section of the ink holding unit 10 is set larger than the diameter of the center portion 22 of the cap 20. The ink holding unit 10 is disposed so as to surround the center portion 22 of the cap 20 by the pair of ink holding units 10 in a state where the cap 20 is covered with the holder 11.

  The ink holding unit 10 is, for example, a porous body impregnated with ink. As the porous body, for example, felt, nonwoven fabric or foam is used. As the ink, an ink in which a pigment or a pigment is dispersed in a solvent is used. As the solvent, an aqueous solvent or an organic solvent that can appropriately disperse the target pigment or dye is generally used, and it is preferable to use a solvent that can be obtained at a low cost and is not harmful to the human body. As the pigments and pigments, it is preferable to use those which are inexpensive and harmless to the human body and which can express the target color.

  The pair of ink holding portions 10 are supported by the support 13 with the end portions protruding, and are accommodated in the holder 11 together with the support 13. The end surface of the portion of each ink holding unit 10 that protrudes from the support 13 constitutes a marking surface 14. The marking surface 14 is a portion that is brought into contact with the upper surface 21 of the cap 20 when marking the upper surface of the cap 20. Since the cross section of the ink holding portion 10 has a uniform arc shape, the marking surface 14 has an arc shape whose radius of curvature is larger than the diameter of the central portion 22 of the cap 20. It is possible to contact the upper surface 21 of the cap 20 so as to surround it.

  The support 13 is accommodated in the holder 11 while supporting the pair of ink holding portions 10 as described above, and is movable relative to the holder 11 in the vertical direction (AB direction). That is, the pair of ink holding portions 10 can also move relative to the holder 11 in the vertical direction (AB direction), similarly to the support 13.

  The holder 11 covers the upper surface 21 when the upper surface 21 of the cap 20 is marked. The holder 11 is formed in a cylindrical shape so as to accommodate the pair of ink holding portions 10 and the support 13. The lower end 15 of the holder 11 is formed in a tapered shape whose diameter increases toward the lower side (B direction). The lower end 15 preferably has a maximum inner diameter set larger than the diameter of the cap 20, while a minimum inner diameter is set smaller than the diameter of the cap 20. Then, the position of the lower end 15 can be regulated while holding the cap 20. In addition to this, if the lower end portion 15 is tapered, the lower end portion 15 serves as a guide when the cap 20 is covered by the holder 11, and the holder 11 (the blood collection tube stamp) with respect to the cap 20. The mounting of 1) becomes easy.

  The operation unit 12 is for moving the ink holding unit 10 relative to the holder 11 in the vertical direction (AB direction), and covers the upper side of the holder 11. The operation unit 12 is connected to the support 13 via a coil spring 16. That is, the operation unit 12 is connected to the ink holding unit 10 via the coil spring 16 and the support body 13.

  Of course, instead of the coil spring 16, other elastic bodies such as a spring other than the coil spring and rubber may be used.

Next, a method of using the blood collection tube stamp 1 will be described.

  As shown in FIG. 4A, when the mark M (see FIG. 5) is applied to the cap 20 of the blood collection tube 2 using the blood collection tube stamp 1, the holder 11 and the cap 20 are first aligned and the holder 11 is aligned. The cap 20 is covered with the lower end portion (guide) 15 of the base plate. Such an operation can be performed very easily without strict alignment because the lower end 15 is tapered. In this manner, the blood collection tube stamp 1 in which the tapered guide 15 is provided on the holder 11 is collected when the mark M (see FIG. 5) is applied to the caps 20 of a large number of blood collection tubes 2 or for urgent specimen inspection. When marking the cap 20 of the blood vessel 2, the convenience is high.

  Next, as illustrated in FIG. 4B, a load directed downward (B direction) is applied to the operation unit 12. At this time, since the holder 11 is in the state of covering the cap 20, the movement of the holder 11 is restricted. Therefore, the operation unit 12 moves downward (B direction) relative to the holder 11.

  When the operation unit 12 is moved downward (B direction), the coil spring 16, the support 13 and the pair of ink holding units 10 connected to the operation unit 12 are also moved downward (B direction). When the pair of ink holding units 10 moves downward (B direction) by a certain distance, the marking surfaces 14 of the pair of ink holding units 10 come into contact with the upper surface 21 of the cap 20. As a result, the ink of the pair of ink holding portions 10 is attached to the upper surface 21 of the cap 20 via the marking surface 14. At this time, since the marking surface 14 has an arc shape having a radius of curvature larger than the diameter of the central portion 22 of the cap 20, the marking surface 14 contacts the upper surface 21 of the cap 20 so as to surround the central portion 22.

  On the other hand, as shown in FIG. 4C, the movement of the pair of ink holding units 10 and the support 13 is restricted when the pair of ink holding units 10 come into contact with the upper surface 21 of the cap 20. Therefore, the operation unit 12 moves further downward (B direction) while compressing the coil spring 16. The operation part 12 is moved downward (B direction) until the coil spring 16 is completely compressed. In a state where the coil spring 16 cannot be compressed, a downward load (B direction) applied to the operation unit 12 causes a downward load (B direction) to act on the support 13 and the pair of ink holding units 10. . Therefore, the marking surfaces 14 of the pair of ink holding units 10 are pressed more strongly against the upper surface of the cap 20. As a result, as shown in FIG. 5, ink adheres to the upper surface 21 of the cap 20 according to the shape of the marking surface 14 of the pair of ink holding portions 10, and the pair of arc-shaped markings are adhered to the upper surface 21 of the cap 20. M is applied. The pair of arc-shaped marks M are formed so as to avoid the central portion 22 on the upper surface 21 of the cap 20.

  As is clear from the above description, the stamp 1 for blood collection tube can mark the upper surface 21 of the cap 20 with an extremely simple operation. Less burden.

  Further, in the blood collection tube stamp 1, the mark M of the cap 20 is formed so as to surround the center portion 22 of the cap 20. That is, the mark M is formed so as to avoid a portion where a blood collection needle or a specimen suction nozzle is inserted. Therefore, the use of the blood collection tube stamp 1 can suppress contamination of the blood collection needle and the sample suction nozzle, and mixing of ink into the sample. As a result, occurrence of measurement errors and measurement errors can be suppressed.

  In addition, since the blood-collecting stamp 1 has a very simple configuration and is small in size, it does not increase the inspection cost as in the case of using an inkjet printing apparatus, and avoids pressing the inspection space. You can also

  In the above embodiment, the blood collection tube in which the central portion of the cap is formed in a convex shape has been described as an example. However, the blood collection stamp 1 can also be applied to a blood collection tube in which the stop portion of the cap is formed in a concave shape. it can.

Next, a blood collection stamp according to the first embodiment of the present invention will be described with reference to FIGS.

  The blood collection tube stamp 3 shown in FIGS. 6 and 7 includes a blood collection tube 2 (FIGS. 6 to 10) in which the central portion 22 of the upper surface 21 of the cap 20 is formed in a convex shape and a blood collection tube 2 (FIG. 6 to FIG. 10) in a concave shape. 11 (a) and 11 (b)). The blood collection tube stamp 3 includes a plurality (four in the figure) of ink holding units 30, holders 31, a plurality (four in the figure) of movable blocks 32, and pressing blocks 33.

  The ink holding unit 30 has an arc shape with a uniform cross section. The radius of curvature of the cross section of the ink holding unit 30 is set to be larger than the diameter of the center portion 22 of the cap 20. When the cap 20 is covered with the holder 31, the center of the cap 20 is covered by the plurality of ink holding units 30. It arrange | positions so that the part 22 may be enclosed. Therefore, the marking surfaces 30 </ b> A of the pair of ink holding portions 30 can be brought into contact with the upper surface 21 of the cap 20 so as to surround the center portion 22 of the cap 20.

  As shown in FIG. 8A, the ink holding unit 30 can move up and down in conjunction with the up and down movement of the movable block 32. More specifically, the ink holding unit 30 is configured to be interlocked with the vertical movement of the movable block 32 that is disposed farthest among the movable blocks 32. For example, the ink holding unit 30 moves down in conjunction with the upward movement of the movable block 32, while moving up in conjunction with the downward movement of the movable block 32. For this reason, the ink holding unit 30 can move downward and protrude through the opening 34 of the holder 31 when the interlocking movable block 32 is moved upward by a predetermined distance or more. Such interlocking of the ink holding unit 30 and the movable block 32 can be achieved, for example, by adopting a link mechanism.

  As shown in FIGS. 8A and 8B, the holder 31 accommodates the ink holding unit 30, the movable block 32, and the pressing block 33, and the ink holding unit 30, the movable block 32, and the pressing block 33 are accommodated. It can be moved in the vertical direction (AB direction) relative to the block 33. The holder 31 has an opening 34 provided at a position corresponding to the ink holding unit 30.

  The opening 34 allows the ink holding unit 30 to protrude from the holder 31. The opening 34 can be opened and closed by an opening / closing lid 35.

  The opening / closing lid 35 is urged upward (direction A) by an elastic member (not shown) such as a spring, and normally closes the opening 34. On the other hand, when the ink holding unit 30 is moved downward (B direction), the opening / closing lid 35 is pressed and rotated by the end 36 of the ink holding unit 30 to open the opening 34. That is, by providing the opening / closing lid 35 that opens and closes the opening 34, it is possible to suppress the ink holding unit 30 from being exposed to the outside air when the blood collection tube stamp 3 is not used. Thereby, inadvertent evaporation of ink from the ink holding unit 30 can be suppressed.

  As shown in FIGS. 7, 8 (a), and 9 (b), the plurality of movable blocks 32 are for projecting the ink holding unit 30 from the opening 34 of the holder 31. The movable block 32 is also disposed so as to surround the pressing block 33, and is used to contact the central portion 22 of the cap 20 when marking the upper surface 21 of the cap 20 together with the pressing block 33 by the blood collection tube stamp 3. Is. The plurality of movable blocks 32 can move independently in the vertical direction (AB direction) with respect to the holder 31, and are connected to the position adjustment holder 37 via a coil spring 38.

  As shown in FIG. 8B, the position adjustment holder 37 is for adjusting the height positions of the plurality of movable blocks 32 and the pressing blocks 33. The position adjustment holder 37 can be moved up and down by rotating, for example, or can be pitched in the vertical direction by a known engagement means. However, when the cap 20 is marked with the blood collection tube stamp 3, the relative position of the position adjustment holder 37 with respect to the holder 31 is fixed, and moves with the holder 31 without moving relative to the holder 31.

  As shown in FIGS. 6 and 9A, the pressing block 33 is for contacting the center portion 22 of the cap 20 when marking the upper surface 21 of the cap 20 with the blood-collecting stamp 3. . That is, the pressing block 33 is used when aligning the blood collection tube stamp 3 with the cap 20 and suppresses concentration of a load on the printing surface 30A of the ink holding unit 30 protruding from the opening 34. Is for. The pressing block 33 is connected to the position adjustment holder 37 via a coil spring 39.

  Of course, the means for connecting the movable block 32 or the pressing block 33 and the holder 31 is not limited to the coil springs 38 and 39, and other elastic bodies such as a spring other than the coil spring and rubber may be used.

Next, a method of using the blood collection tube stamp 3 will be described.

  As shown in FIG. 9A, when marking the cap 20 of the blood collection tube 2 using the blood collection tube stamp 3, the plurality of movable blocks 32 and the pressing blocks 33 are aligned with the cap 20. In this state, a load directed downward (B direction) is applied to the holder 31. Thereby, the plurality of movable blocks 32 and the pressing block 33 interfere with the central portion 22 of the cap 20. On the other hand, the holder 31 and the position adjustment holder 37 move downward (B direction) relative to the plurality of movable blocks 32 and the pressing block 33 while compressing the coil springs 38 and 39.

  When the holder 31 moves down relative to the movable block 32, the movable block 32 moves up relative to the holder 31. Therefore, the ink holding unit 30 interlocked with the movable block 32 moves downward (B direction) relative to the holder 31, pushes the opening / closing lid 35, and protrudes through the opening 34 of the holder 31. As a result, the marking surface 30A of the ink holding unit 30 presses the upper surface 21 of the cap 20, and ink adheres to the upper surface 21 of the cap 20 following the shape of the marking surface 30A of the ink holding unit 30. As shown in FIG. 9B, four arc-shaped marks M are formed on the upper surface of the cap 20 by the adhesion of ink. These arc-shaped marks M avoid the central portion 22 on the upper surface 21 of the cap 20. Accordingly, if the mark M is applied to the cap 20 using the blood collection tube stamp 3, the contamination of the blood collection needle and the sample suction nozzle or the mixing of ink into the sample can be suppressed. Can be suppressed.

  On the other hand, as shown in FIG. 10A, when the movable block 32 has failed to be aligned with the central portion 22 of the cap 20 and a part of the movable block 32 is displaced from the central portion 22 of the cap 20. Let's assume. In the configuration in which the plurality of movable blocks 32 are arranged so as to surround the pressing block 33, even if a slight positional deviation occurs, some of the movable blocks 32 come into contact with the center portion 22 of the cap 20 and are above the holder 31. Be moved. Therefore, the marking surface 30 </ b> A is brought into contact with the upper surface 21 of the cap 20 in some of the plurality of ink holding units 30. Therefore, as shown in FIG. 10B, in the blood collection tube stamp 3, even if there is some problem in the alignment of the movable block (the blood collection tube stamp 3) with respect to the center portion 22 of the cap 20, A mark M can be applied to the upper surface 21. This mark M also avoids the central portion 22 on the upper surface 21 of the cap 20.

  In the above-described example, the central portion 22 on the upper surface 21 of the cap 20 is formed in a convex shape. However, as shown in FIG. Even the depressed blood collection tube 2 can be applied. In this case, the movable block 32 and the pressing block 33 are provided at the center portion (inner surface of the recess) 22 of the cap 20 as it is when the stamp 3 for blood collection tube is applied to the cap 20 having the center portion 22 formed in a convex shape. There is a risk that it cannot be fully contacted. Therefore, the position adjustment holder 37 is displaced downward (B direction) with respect to the holder 31 to displace the movable block 32 and the pressing block 33 with respect to the holder 31, and the position adjustment holder 37 is fixed to the holder 31. Thereby, these blocks 32 and 33 can be fixed to the holder 31 in the state where the protrusion distance of the movable block 32 and the pressing block 33 from the holder 31 is large. As a result, even if the central portion 22 of the cap 20 is the concave blood collection tube 2, the movable block 32 is brought into contact with the central portion (inner surface of the concave portion) 22 of the cap 20 as shown in FIG. Thus, the marking surface 30 </ b> A of the ink holding unit 30 can be brought into contact with the upper surface 21 of the cap 20. Even in the cap 20 in which the central portion 22 is recessed, even if the alignment of the movable block 32 is somewhat insufficient, a part of the plurality of movable blocks 32 is brought into contact with the central portion 22 of the cap 20. Therefore, the mark M can be applied to the upper surface 21 of the cap 20 (see FIG. 10B).

Next, a blood collection stamp according to a second embodiment of the present invention will be described with reference to FIGS. In these drawings, the center of the cap 20 of the blood collection tube 2 will be described as an example where the central portion of the cap 20 of the blood collection tube 2 is formed in a convex shape into which a sample aspirating nozzle in the analyzer is inserted.

  The blood collection tube stamp 4 shown in FIGS. 12 and 13 includes a plurality (four in the figure) of an operation unit 40, a plurality of ink holding units 41, and a holder.

  The plurality of operation units 40 support the ink holding unit 41 and can be moved relative to the holder 42 independently of each other. A coil spring 43 is disposed below the operation unit 40. The coil spring 43 urges the operation unit 40 upward, and is disposed so as to surround the ink holding unit 41.

  Of course, the means for biasing the operation unit 40 upward is not limited to the coil spring 43, and other elastic bodies such as a spring other than the coil spring and rubber may be used.

  The ink holding part 41 has an arc shape with a uniform cross section. The radius of curvature of the cross section of the ink holding portion 41 is set to be larger than the diameter of the center portion 22 of the cap 20. When the cap 20 is covered with the holder 42, the center of the cap 20 is covered by the pair of ink holding portions 41. It arrange | positions so that the part 22 may be enclosed.

  The ink holding unit 41 is movable in the vertical direction (AB direction) together with the operation unit 40. That is, the ink holding unit 41 is completely accommodated in the holder 42 in a state where no load is applied to the operation unit 40, while a downward load (B direction) is applied to the operation unit 40. Sometimes it can project through the opening 44 of the holder 42. The opening 44 can be opened and closed by an opening / closing lid 45.

  The opening / closing lid 45 is urged upward (direction A) by an elastic member (not shown) such as a spring, and normally closes the opening 44. On the other hand, the opening / closing lid 45 is pressed and rotated by the end portion 48 of the ink holding portion 41 when the ink holding portion 41 is moved downward (B direction) to open the opening 44. By providing such an opening / closing lid 45, it is possible to prevent the ink in the ink holding part 41 from evaporating inadvertently.

  Further, a pressing block 47 is connected to the holder 42 via a coil spring 46. The pressing block 47 is for contacting the central portion 22 of the cap 20 when marking the upper surface 21 of the cap 20 with the blood collection tube stamp 4. That is, the pressing block 47 is used when aligning the blood collection tube stamp 4 with the cap 20 and suppresses concentration of the load on the marking surface 49 of the ink holding portion 41 protruding from the opening 44. Is for.

  Of course, the means for connecting the pressing block 47 and the holder 42 is not limited to the coil spring 46, and other elastic bodies such as a spring other than the coil spring and rubber may be used.

  Next, a method of using the blood collection tube stamp 4 will be described.

  First, as illustrated in FIG. 14A, the operation unit 40 that supports the target ink holding unit 41 is pressed downward (B direction). When the operation unit 40 is moved downward (B direction), the ink holding unit 41 moves downward (B direction) together with the operation unit 40 while compressing the coil spring 43. As a result, the end 48 of the ink holding part 41 pushes the opening / closing lid 45, and the ink holding part 41 protrudes from the opening 44 of the holder 42.

  Next, as shown in FIG. 14B, the marking surface 49 of the ink holding portion 41 protruding from the opening 44 is brought into contact with the upper surface 21 of the cap 20 while aligning the pressing block 47 with the center portion 22 of the cap 20. . As a result, the ink in the ink holding portion 41 is attached to the upper surface 21 of the cap 20 through the marking surface 49.

  On the other hand, when the load on the operation unit 40 is released, the operation unit 40 and the ink holding unit 41 are moved upward (direction A) by the elastic force of the coil spring 43 and returned to their original positions. At the same time, the opening / closing lid 45 returns to its original position, and the opening 44 is closed by the opening / closing lid 45.

  In this way, if the pressing block 47 is aligned with the center portion 22 of the cap 20, the pressing block 47 comes into contact with the center portion 22 of the cap 20. For this reason, in the blood collection tube stamp 4, it is possible to prevent the marking surface 49 of the ink holding portion 41 from coming into contact with the central portion 22 of the cap 20 and to press the marking surface 49 against the upper surface of the cap 20 with a moderate force. .

  Further, by selecting the ink holding portion 41 to be protruded from the opening of the holder 42, as shown in FIG. 15A to FIG. A simple pattern mark M can be applied.

  Further, in the blood collection tube stamp 4, if each of the plurality of ink holding portions 41 holds inks of different colors, it is possible to distinguish the type of specimen by the color of the mark M, and the color of the mark M By combining the patterns of and M, it becomes possible to distinguish many types of information.

  In the above embodiment, the blood collection tube in which the central portion of the cap is formed in a convex shape has been described as an example. However, the blood collection stamp 1 can also be applied to a blood collection tube in which the stop portion of the cap is formed in a concave shape. it can.

  The present invention is not limited to the embodiments described above, and can be variously modified. For example, the mark formed on the cap is not limited to an arc shape, but may be another shape such as a straight line shape.

  It is not always necessary to provide a plurality of ink holding units, and one ink holding unit may be provided depending on the application. In this case, the marking surface of the ink holding portion may be an arc shape, a linear shape, an annular shape, or other shapes.

  When the needle insertion portion for inserting the blood collection needle in the blood collection tube is not the central portion on the upper surface of the cap, the blood collection tube stamp may be configured so as to avoid the needle insertion portion and mark the central portion on the upper surface of the cap. It is not necessary to configure the blood collection tube stamp so as to avoid the mark.
