Abstract

PROBLEM TO BE SOLVED: To enable spotting of a necessary amount of solution to be measured on a concentration measuring device with a simple structure and working by bending a tip part of a long-sized body having a grip part at a specified angle across the thickness to form an opening of a specified size containing the bent part by piercing. SOLUTION: A tip part of the body 1 having a grip part 4 made of ABS, nylon or the like is bent at a specified angle (about 60 deg.) across the thickness, an opening 2 with a specified diameter containing the bent part is formed by piercing and a slit 3 following the opening 2 is formed at the tip part to be opened at a tip face of the body 1. Holding the grip part 4 of a spotting aid thus arranged, for example, a solution to be measured is dripped at the opening 2 from an injector or the opening 2 is brought into contact with a finger tip ready for running humor (blood or the like) by puncturing or the like. Thus, a specified amount of the solution to be measured determined by the size of the opening 2, the thickness of the body 1 or the like can be held at the opening 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spotting aid, and more specifically, it can simplify and ensure the work of spotting a required amount of a solution to be measured on a measuring device. Regarding the ingredients.

[0002]

2. Description of the Related Art Conventionally, when a required amount of a solution to be measured such as blood is spotted on a concentration measuring device such as a blood glucose measuring device, a spotting aid such as a capillary or a dropper is used, or a syringe is used. Are using. In any case, the required amount of the solution to be measured can be spotted on the electrode surface of the concentration measuring device if the operation is not mistaken.

[0003]

However, the capillary,
When using a spotting aid such as a dropper and the solution to be measured is a body fluid such as blood, it is necessary to suck the body fluid into the spotting aid and push it out of the spotting aid. Therefore, in the case of body fluid that is collected with a syringe, such as blood, it is necessary to drip the body fluid from the syringe to another location, and then perform suction and extrusion, which is a disadvantage of poor workability. .

Further, when using the syringe, complicated work such as when using a capillary or a dropper is unnecessary, but it is difficult to control the force when operating the syringe, and excessive force is applied. In that case, there is a disadvantage that the piston of the syringe moves more than necessary and a remarkably large amount of body fluid is spotted on the concentration measuring device. Then, in this case, the excess body fluid invades the periphery of the concentration measuring electrode and the like and is then dried and solidified, so that the increase in the spotted amount cannot be tolerated.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, has a simple structure, and can apply a required amount of a solution to be measured to a concentration measuring device with a simple operation. The purpose is to provide a spotting aid.

[0006]

According to another aspect of the present invention, there is provided a spotting aid, wherein a distal end portion of a long body having a grip portion is bent at a predetermined angle in a thickness direction and includes the bent portion. An opening of a predetermined size is formed therethrough. The spotting aid of claim 2 is
A slit continuous with the opening is formed so that the slit is opened at the tip of the main body.

In the spotting aid of claim 3, the width of the opening and the width of the slit are set to be equal to each other.

[0008]

According to the spotting aid of claim 1, the distal end portion of the elongated main body having the grip portion is bent at a predetermined angle in the thickness direction, and an opening of a predetermined size is included so as to include the bent portion. Since it is formed through, the solution to be measured is dropped from the syringe to the opening while holding the grip, or the opening is touched by touching the opening with a fingertip that is in a state where body fluid is discharged by puncture. In addition, it is possible to hold a predetermined amount of the solution to be measured, which is determined by the size of the opening, the thickness of the main body, and the like. Then, after that, the solution to be measured held in the opening can be spotted by bringing the opening close to or in contact with the concentration measuring device. Therefore, it is possible to improve the workability for spotting the solution to be measured, and it is possible to prevent the disadvantage that the amount of the solution to be measured spotted becomes unnecessarily large.

In the spotting aid according to the second aspect of the present invention, since the slit continuous with the opening is formed through and the slit is opened at the tip of the main body, the body fluid can be discharged by puncturing or the like. By bringing the opening of the slit into contact with the fingertip or the like, the body fluid is sucked up to the opening by the capillary phenomenon. Therefore, workability for holding the solution to be measured in the opening can be further enhanced.

In the spotting aid of claim 3, since the width of the opening and the width of the slit are set to be equal to each other, the manufacturing work can be simplified and the same effect as in claim 2 can be achieved. can do.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of the spot application aid of the present invention, FIG. 2 is a side view, and FIG.
FIG. 4 is a central longitudinal sectional view of a main part, and FIG. 4 is a view indicated by an arrow IV in FIG. In this spotting aid, the tip of the main body 1 made of ABS, nylon or the like is slid at a predetermined angle in the thickness direction (for example, 60
°) It is bent, and a circular opening 2 having a predetermined diameter is formed so as to penetrate therethrough including the bent portion. Then, a slit 3 which is continuous with the opening 2 is formed through the tip portion, and the slit 3 is opened at the tip surface of the main body 1. Further, both side surfaces of the tip portion are tapered so that the width on the tip side becomes small. Further, the base portion of the main body 1 is a grip portion 4 formed in a slightly wide width, and the grip portion 4 is formed with bulging portions 4a extending in the width direction at predetermined intervals in the length direction.

FIG. 5 is a schematic view for explaining a series of operations for spotting a solution to be measured on a spotted portion of a concentration measuring device using the spotting aid. Note that, for convenience of description, the lower side of FIG. In FIG. 5, A is a syringe 2.
The figure shows a state in which the solution 40 to be measured is dropped onto the spotting aid 30 from 0, and the solution 40 to be measured dropped onto the spotting aid 30 is held by the opening 2 and the slit 3. In this case, it is considered that a remarkably large amount of the solution to be measured is dropped from the syringe 20, but in this case, the excess solution to be measured is spilled from the spotting aid 30, so an appropriate amount of the solution to be measured is dropped. Only the solution can be retained.

In FIG. 5, B is the slit 3 of the spotting aid 30 at the fingertip from which blood (solution to be measured) 40 has come out by puncture or the like.
2 shows a state in which the openings of the two are brought into contact with each other, and blood 40 is sucked up to the openings 2 by the capillary phenomenon of the slits 3,
Will be retained. In any case, the held measurement target solution 40 bulges toward the back surface of the spotting aid 30 due to surface tension (see C in FIG. 5).

C in FIG. 5 shows a state in which the solution to be measured is spotted on the spotted portion 50 of the concentration measuring device from the spotting aid 30 holding the solution to be measured 40 by A or B in FIG. By holding the grip portion 4 of the spotting aid 30 and bringing the back surface of the tip end into contact with the spotted portion 50, spotting can be easily achieved. Although the slit 3 is formed in addition to the opening 2 in the above-described embodiment, the slit 3 may be formed as shown in FIG. 6 if the workability for holding the solution to be measured can be slightly reduced. 3 may be omitted.

FIG. 7 is a plan view showing another embodiment of the spotting aid of the present invention. This embodiment is different from the above embodiment only in that the width of the slit 3 is set to be slightly wider than that of the above embodiment, and the opening 2 is set to a slit shape having the same width as the slit 3. Therefore, in the case of this embodiment, the capillarity caused by the slits 3 is somewhat reduced, but it is possible to achieve an operation substantially similar to that of the above embodiment.

EXAMPLE In the embodiment shown in FIG. 1, the main body has a thickness of 1 m.
m, the radius of the opening 2 is 1.2 mm, and the width of the slit 3 is 0.
8 mm (Example 1), and in the embodiment of FIG. 7, the thickness of the main body is 1 mm, and from the bent portion of the opening 2 to the grip portion 4.
The length to the side is 1.5 mm, the width of the slit 3 is 1.5 mm
(Example 2).

Then, pipette a fixed amount (5 μl, 10 μl
l) Is it possible to drop the deposited blood on the spotting aid, and to deposit the blood from the back surface of the spotting aid on almost the entire surface of a predetermined spotted part (for example, a diffusion limiting film that is brought into contact with the concentration measurement electrode)? It was judged whether or not. As a result, in the case of Example 1, 5 μl
It was slightly good, and 10 μl was good. Further, in the case of Example 2, 5 μl was poor and 10 μl was slightly good.

In addition, pipette fixed quantity (5μl, 10μ
l) The dropped blood is dropped on the fingertip, and the blood at the fingertip is transferred to the spotting aid, and then a predetermined spotted portion (for example, a diffusion limiting film that is brought into contact with the concentration measurement electrode) from the back surface of the spotting aid. It was determined whether blood could be spotted on almost the entire surface of the. As a result, in the case of Example 1, 5 μl was defective, and 10 μ
1 was good. In the case of Example 2, 5 μl
Was poor, and 10 μl was slightly good.

It should be noted that the amount of blood that can be spotted on a predetermined spotted portion from the back surface of the spotting aid by dropping two drops of blood from a bottle (for example, a standard solution bottle for calibration) onto the spotting aid. Since it is 21 μl, the required amount of the solution to be measured can be spotted without any inconvenience in normal use.

[0020]

According to the invention of claim 1, the workability for spotting the solution to be measured can be improved, and the amount of the solution to be measured spotted becomes unnecessarily large. It has a unique effect that it can be prevented. The invention of claim 2 can further enhance the workability for holding the solution to be measured in the opening, and can achieve the same effect as that of claim 1.

According to the invention of claim 3, the manufacturing work can be simplified and the same operation as that of claim 1 can be achieved.
