Description

  The present invention relates to an adhesive sheet or the like for positioning a sensor unit at a predetermined position on the body of a subject, and in particular, even if the length of the injection needle is different, the sensor unit is accurately positioned near the needle tip of the injection needle. The present invention relates to a pressure-sensitive adhesive sheet with release paper that can be positioned on the surface.

At present, CT (Computed Tomography) scanner, MRI (Magnetic Resonance Imaging) apparatus, PET (Positron) as medical diagnostic imaging equipment.
Emission Tomography) devices are known. When using such an imaging apparatus, a subject may be injected with a contrast medium, physiological saline, or the like (hereinafter, also simply referred to as “medical solution”).

In this chemical solution injection, the tip of the injection needle may come off the subject's blood vessel, and the contrast medium may be injected subcutaneously (referred to as “extravascular leakage”). For example, Patent Document 1 discloses a technique for detecting such extravasation.
The leak detection unit described in this document has a light emitting diode that irradiates a part of a subject's body with infrared light having a predetermined wavelength, and a phototransistor that receives the reflected light, and observes the intensity change of the reflected light. Thus, the presence or absence of extravasation is determined.
In the same document, it is described that a leak detection unit is fixed to a subject's body using an adhesive sheet.

WO2006 / 030764

  In order to satisfactorily detect extravasation using the leak detection unit as described above, it is necessary to accurately place the injection needle at a predetermined position (for example, near the needle tip of the injection needle). When the leak detection unit is not arranged at a predetermined position, there is a possibility that accurate leak detection cannot be performed, or leak detection cannot be performed at all.

In order to arrange the leakage detection unit at an accurate position, first, it is necessary to attach the adhesive sheet itself to a predetermined position accurately. In that case, for example, it is conceivable that the adhesive sheet can be accurately positioned at a predetermined position by printing a guide mark on the adhesive sheet. However, in this case, it is necessary to increase the size of the pressure-sensitive adhesive sheet. With such a large pressure-sensitive adhesive sheet, it is difficult to cope with a narrow part or a movable part (for example, the inner side of the elbow).
In general, the length of the injection needle varies depending on the manufacturer, but even if the length of the needle differs in this way, the leak detection unit is accurately placed at the needle tip position corresponding to each needle. It is desirable that it can be fixed to.

  The present invention has been made in view of the above problems, and the purpose thereof is to accurately position the leakage detection unit near the tip of the injection needle even if the length of the injection needle is different. An object is to provide an adhesive sheet with release paper and a sheet kit including the same.

The pressure-sensitive adhesive sheet with release paper of the present invention for solving the above problems is
An adhesive sheet that is affixed near the tip of an injection needle punctured in the body of the subject and positions the sensor unit at that position;
Surface release paper affixed to one side of the adhesive sheet;
A back release paper affixed to the other surface of the adhesive sheet;
An adhesive sheet with release paper comprising:
The front release paper or the back release paper has an extending part extending from the outer peripheral part of the pressure-sensitive adhesive sheet in a state where they are stuck to the pressure-sensitive adhesive sheet,
The extending portion is provided with a puncture position mark indicating the distance from the puncture position where the injection needle is punctured to the body of the subject to the needle tip of the injection needle.
The “sensor unit” may be a leakage detection unit for detecting extravasation, but may be a detection unit other than that (for example, one that detects blood flow).
The “puncture position mark” may be displayed with a symbol such as a dot or a line, or may be displayed with a number.

According to such a configuration, since the puncture position mark indicating the distance from the puncture position of the injection needle to the needle tip position is provided, the adhesive sheet is accurately pasted near the needle tip using the mark. As a result, the sensor unit can be accurately positioned.
In particular, since the puncture position mark is provided not on the adhesive sheet but on the release sheet that is finally peeled off, it is not necessary to increase the size of the adhesive sheet itself.

  Further, the present invention may be as follows.

  A plurality of puncture position marks are provided corresponding to the length of the injection needle.

The puncture position mark is provided on the extending portion of the front release paper.
As the extending portion of the front release paper, two extending portions are provided which are located on both sides of the injection needle and are formed so as to extend along the injection needle.

The front release paper further has a guide mark indicating the position of the tip of the injection needle.
The pressure-sensitive adhesive sheet further has a mark indicating a position where the sensor unit is attached.

  As described above, according to the present invention, there is provided an adhesive sheet with release paper and the like that can accurately position the leakage detection unit near the tip of the injection needle even if the length of the injection needle is different. be able to.

It is a figure showing a sheet kit of one form of the present invention. It is a top view of the adhesive sheet of FIG. It is sectional drawing in the AA of FIG. It is a top view of front release paper. It is a top view of back release paper. It is a figure for demonstrating the usage method of the sheet kit of FIG. 1 (peeling). It is a figure for demonstrating the usage method of the seat kit of FIG. 1 (pasting). It is a top view which shows the positional relationship of the injection needle in the state of FIG. It is a figure for demonstrating the usage method of the seat kit of FIG. 1 (fixation).

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the sheet kit 100 includes a pressure sensitive adhesive sheet 30 with release paper affixed to the front and back (this state is referred to as a pressure sensitive adhesive sheet 50 with release paper) and a code of a leakage detection unit described later. A fixing tape 58 for fixing to a part of the body and a cover tape 55 attached to the body of the subject so as to cover the leakage detection unit are provided.

First, an injection needle, a leakage detection unit, and the like used in the present embodiment will be described with reference to FIGS.
The base of the injection needle 12 is held by a holding member 13, and a chemical liquid tube 15 is connected to the holding member 13. The other end (not shown) of the chemical liquid tube 15 is connected to, for example, a syringe attached to the injection head.
By injecting the injection needle 12 into the body of the subject (in this example, the arm) and operating the injection head with the needle tip communicating with the blood vessel A of the subject (see FIG. 9), the drug solution is injected into the blood vessel. The

  As shown in FIG. 9, the leakage detection unit 18 includes a light emitting diode, a phototransistor, and the like in a flat cylindrical housing. As the leakage detection unit 18 itself, a conventionally known one can be used. Although not shown in the figure, a plurality of openings are provided on the lower surface of the housing, whereby light from the light emitting diodes in the housing is irradiated through the openings toward the surface of the subject's body, The reflected light passes through another opening, passes through the opening, returns to the housing, and is received by a phototransistor or the like. As an example, the leakage detection unit 18 is connected to a control device (not shown) via a cord 18a.

When the needle tip of the injection needle 12 is detached from the blood vessel A and extravasation occurs, the specific wavelength of the irradiated light is absorbed by the leaked contrast agent (one example), and as a result, compared with normal time. The intensity of a specific wavelength in the reflected light is reduced. The presence or absence of extravasation can be determined by looking at the change in the reflection intensity.
Note that the method for detecting leakage is not limited to the above, and other various methods may be used.

  In the following description, the position where the injection needle 12 is punctured into the body of the subject as shown in FIG. 8 is referred to as a puncture position P2, and the position of the tip of the injection needle is referred to as a needle tip position P1.

With reference to FIG. 1 again, the adhesive sheet with release paper 50 will be described.
This pressure-sensitive adhesive sheet with release paper 50 has adhesiveness on both sides, a pressure-sensitive adhesive sheet 30 used to stick the leak detection unit 18 to the body of the subject, a front release paper 20 stuck on the surface thereof, And a back release paper 40 attached to the back surface.

  As shown in FIG. 2, the outline shape of the adhesive sheet 30 of this example is substantially circular as a whole. Specifically, the adhesive sheet 30 includes a circular main body 31 that is a portion to which the leakage detection unit 18 is attached, and two projecting portions 31 a and 31 b formed on the outer peripheral portion of the main body 31. Yes. As an example, the pressure-sensitive adhesive sheet 30 is made of a transparent resin sheet having flexibility.

  The adhesive sheet 30 is printed with a ring-shaped mark 33 indicating the position where the leakage detection unit 18 is attached. Although not particularly limited, the size of the ring-shaped mark 33 is slightly smaller than the size of the main body 31 of the adhesive sheet 30 and corresponds to the housing shape of the leakage detection unit 18.

  As shown in FIG. 3, adhesiveness may be imparted to the adhesive sheet 30 by forming adhesive layers 37, 37 on both surfaces of the sheet substrate 35. The adhesive layer 37 may have a circular outline. For example, the adhesive layer 37 is formed in a circular region (diameter d2) that is slightly smaller than the main body 31 (diameter d1). It is good also as a structure in which the adhesion layer 37 is not formed.

  As shown in FIG. 2, a dot-like mark 38 is printed at the approximate center of each protrusion 31a, 31b.

  Next, the front release paper 20 and the back release paper 40 will be described with reference to FIGS. 4 and 5. These release papers 20 and 40 are basically formed in the same contour shape except for a part.

  As shown in FIG. 5, the back release paper 40 has a contour shape like a vertically long rectangle as a whole. Specifically, the lower release region 42 (substantially rectangular) picked up by the subject when peeling off. ) And an upper region 41 formed so as to be slightly tapered upward from there. The front end side of the upper region 41 is curved in a gentle arc shape according to the curve of the adhesive sheet 30. The adhesive sheet 30 is affixed to the upper region 41.

  As shown in FIG. 4, the front release paper 20 includes an upper region 21 having substantially the same shape as the lower region 41 of the back release paper 40, and two extending portions 22 a extending downward from the upper region 21 in parallel with each other. , 22b.

The material of the release paper is not particularly limited. For example, a release layer made of a silicone resin (one example) may be formed on one surface of a paper base.
Further, the color of the base material may be white, for example, and the release paper as a whole may be semi-transmissive. When the front release paper 20 is translucent, the circular mark 33 on the pressure sensitive adhesive sheet 30 can be visually recognized through the front release paper 20 in a state where the front release paper 20 is stuck on the pressure sensitive adhesive sheet 30 (FIG. 1). According to this, when sticking the adhesive sheet 30 on a test subject's body so that it may mention later, it becomes easier to align this adhesive sheet.

  As shown in FIG. 4, a cross guide 27 that is a mark indicating the needle tip position of the injection needle is printed on the upper region 21 of the front release paper 20. The center (intersection point) of the cross corresponds to the center of the adhesive sheet 30.

As shown in FIG. 4, one extending portion 22 a has three dot-shaped puncture position marks 28-1 to 28-3 in this example (hereinafter also referred to as “puncture position mark 28 without distinguishing these”). Is printed along its length. The puncture position mark 28 indicates the distance from the puncture position P2 (see FIG. 8) of the injection needle 12 to the needle tip position P1 of the injection needle.
As an example, the mark 28-3 farthest from the base portion 21 among the three puncture position marks 28 corresponds to a needle length of 48 to 51 mm. The intermediate mark 28-2 corresponds to the needle length of 30 to 45 mm, and the mark 28-1 closest to the base portion 21 corresponds to the needle length of 14 to 25 mm.

  As shown in FIG. 1, the extended portions 22 a and 22 b of the front release paper 20 overlap the back release paper 40 in a state where the release papers 20 and 40 are pasted on both sides of the adhesive sheet 30. .

  In the case of a configuration in which only the extension portions 22a and 22b extend instead of such a configuration, the extension portions 22a and 22b are likely to be deformed or damaged during distribution or storage, for example. On the other hand, according to the configuration of the present embodiment, since the extension portions 22a and 22b overlap the back release paper 40, the extension portions 22a and 22b can be prevented from being deformed or damaged. Handleability is improved.

  Moreover, as will be described later, the back surfaces (surfaces facing the back release paper) of the extended portions 22a and 22b of the front release paper 20 are portions that come into contact with the body of the subject. When 22a and 22b are overlapped on the back release paper 40, basically, the back surfaces of the extending portions 22a and 22b are not exposed until the back release paper 40 is peeled off. It is.

  As shown in FIG. 1, in the state where the release papers 20 and 40 are pasted on both sides of the pressure-sensitive adhesive sheet 30, a part of the back release paper 40 is exposed between the extending portions 22 a and 22 b. When the back release paper 40 is peeled off, the back release paper 40 can be peeled off by picking up the exposed area, and thus is easily peeled off.

Next, the fixing tape 58 and the cover tape 55 will be described.
As an example, both the fixing tape 58 and the cover tape 55 are bandage-like tapes in which an adhesive layer is provided on one side of a cloth base material.

The fixing tape 58 is for fixing the cord 18a of the leakage detection unit 18, and as shown in FIG. 1, the outline shape is a rectangle.
The cover tape 55 is affixed so as to cover the leakage detection unit 18, a circular main body portion 55a that covers the leakage detection unit 18, and band portions 55b that are formed on both sides and extend outward in the radial direction. 55b.

  As shown in FIG. 1, the cover tape 55 may have a cut 59 so that the tape can be easily peeled off from the body of the subject. The cut 59 may be a vertical cut that divides the cover tape into left and right, or a horizontal cut that divides the cover tape up and down.

Although illustration is omitted, the release paper attached to the adhesive layer side of the fixing tape 58 is divided into two or more with a notch in the vicinity of the center (example) so that the release paper can be easily peeled off. May be. Similarly, the release paper pasted on the cover tape 55 may be divided into two or more by cutting into the vicinity of the central portion (an example).

  The adhesive sheet 50 with release paper, the fixing tape 58, and the cover tape 55 shown in FIG. 1 may be put in one bag (not shown). Thus, when the adhesive sheet 50, the fixing tape 58, and the cover tape 55 are handled as one kit, a doctor or the like needs to prepare each of the adhesive sheet 50 and the tapes 55 and 58 at a medical site. There is no. That is, since all the members for fixing the leakage detection unit 18 are prepared, there is no possibility of missing parts, and the unit 18 can be fixed satisfactorily.

A method of using the seat kit 100 of the present embodiment configured as described above will be described below.
First, as shown in FIG. 6, the back release paper 40 is peeled off. Thereby, it will be in the state where the back of adhesive sheet 30 was exposed.

  Next, as shown in FIG. 7, the pressure-sensitive adhesive sheet 30 with the front release paper 20 is attached to the body of the subject. This sticking is performed after puncturing the injection needle 12. Before pasting, the area around the pasting position is wiped off.

As shown in FIG. 8, the adhesive sheet 30 is attached to a position where the center of the cross guide 27 on the surface of the front release paper 20 overlaps the needle tip position P1.
Usually, since the distal end side of the injection needle 12 is inserted into the body of the subject and cannot be visually observed, it is not easy to stick the adhesive sheet at an accurate position. However, according to the present embodiment, as shown in FIG. 8 (showing the case of a needle having a length of 30 to 45 mm), positioning is performed so that the puncture position mark 28-2 and the puncture position P1 are aligned. The needle tip position P1 and the center of the cross guide 27 can be accurately aligned.

  Furthermore, according to this embodiment, as shown in FIG. 8, the ring-shaped mark 33 of the adhesive sheet 30 underneath can be visually recognized even with the front release paper 20 attached. Positioning can also be performed using the shape mark 33 as a guide, and more accurate pasting is possible.

If the adhesive sheet 30 is affixed on a test subject's body, then the front release paper 20 will be peeled off. Thereby, only the adhesive sheet 30 is left in the subject's body.
Next, the leak detection unit 18 is attached so that the leak detection unit 18 is positioned on the ring-shaped mark 33 of the adhesive sheet 30. At this time, the sensor cable 18a is pulled out to the opposite side (upper side in FIG. 9) from the puncture position P2 so as not to reach the puncture position P2.

  Next, a fixing tape 58 is applied to fix the sensor cable 18a to the subject's body. Thereafter, the cover tape 55 is applied to firmly fix the leakage detection unit 18. The cover tape 55 is affixed so as to cover the leak detection unit 18 from above, whereby the leak detection unit 18 is more securely fixed, and the lower surface of the leak detection unit 18 is firmly attached to the surface of the subject's body. Since they are in close contact with each other, accurate leak detection can be performed.

The leakage detection unit 18 can be removed by the following procedure (example).
First, the cover tape 55 is peeled off. In this embodiment, since the cut 59 is formed in the cover tape 55, the cover tape 55 can be peeled off by half (or by 1/4). When such a cut 59 is not formed, depending on the method of peeling, the leak detection unit 18 and the adhesive tape 30 may be peeled off together with the cover tape 55. However, if the cover tape 55 can be peeled off by half (or by 1/4), the leakage detection unit 18 and the adhesive tape 30 can be carefully peeled one by one.

According to the adhesive sheet with release paper 50 of the present embodiment described above, the puncture position mark 28 indicating the distance from the puncture position P2 of the injection needle to the needle tip position P1 of the injection needle is provided. The adhesive sheet 30 can be accurately pasted in the vicinity of the needle tip by using the above, and as a result, the unit 18 can be accurately positioned.
Particularly, since the puncture position mark 28 is provided not on the adhesive sheet 30 but on the release sheet 20 to be finally peeled off, it is not necessary to increase the size of the adhesive sheet 30 itself.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications can be made.
For example, the puncture position mark 28 may be provided in both of the extending portions 22a and 22b. Alternatively, the puncture position mark may be provided on the back release paper 40 instead of the front release paper 20.

The shape of the pressure-sensitive adhesive sheet 30 can be appropriately changed according to the shape of the leakage detection unit 18 to be used, and may be, for example, a quadrangle or a polygon.
The mark indicating the needle tip position of the injection needle printed on the front release paper 20 is not necessarily limited to a cross, and any shape can be used as long as it can indicate the needle tip position.
