Description

Description: TECHNICAL FIELD The present invention relates to an auxiliary device for safely and reliably injecting an injection solution from an injection solution ampoule into an insulin self-injection solution for an amblyopia person. is there.

[Prior Art] Conventionally, there has been no particular auxiliary device for injecting an injection solution in an injection solution ampoule into a syringe.

[Problems to be Solved by the Invention] Therefore, it is very difficult for a visually impaired person who often has a self-injection of insulin to diabetic patients to accurately insert the tip of the injection needle into the rubber portion of the head of the ampoule. It was difficult. Therefore, when inserting the tip of the injection needle into the rubber part of the ampoule, accidents such as accidentally piercing the fingertip or damaging the needlepoint by piercing the aluminum metal fitting part for fixing the rubber have occurred. Also, of course,
It was also very difficult to read the insulin injection amount specified by the doctor from the scale on the syringe. However, these things were overlooked as unavoidable because of blindness, and they were covered by relying on the care of family members.

The inventor of the present invention was keenly aware that this solution was a problem of the eyebrow from his own experience, and researched and developed an insulin injection auxiliary device that can be safely and reliably operated by a visually impaired person or a blind person.

[Means for Solving the Problems] The present invention will be described below with reference to the drawings. The rubber part 3 of the head of the ampoule 2 for the injection solution is housed in one of the main bodies 1 of the insulin injection assisting device. An ampoule receiver 4 is provided. In the drawing, as the simplest shape, a semi-cylindrical shape in which the tube wall of the ampoule 2 is fitted by a little elasticity is shown, but it may be a container shape in which elasticity is not used, and is detachable by a lid. It may be one that does. In order to prevent the front and rear positions of the ampoule 2 to be stored from being displaced, the ampoule receiver 4 is provided with, for example, a stopper 5 for holding the lower part of the neck of the ampoule in the illustrated one. However, depending on the shape of the ampoule receiver 4, this stopper 5 may be attached to the bottom of the ampoule so that the ampoule 2 can be rotated but cannot be moved inward by elasticity or other method of the container itself. You can

Next, when the ampoule 2 is fitted in or stored in the ampoule receiver 4, a syringe receiver 7 is provided on which the syringe 6 can be placed and slid by an axis slightly offset from the axis of the ampoule 2 with a slight distance in front of the ampoule 2. To provide.

The syringe receiver 7 is for linearly mounting and sliding the syringe 6, and is divided into two parts in the drawing, but of course, the gap is made narrower, Alternatively, one groove may be formed by connecting without removing the gap.

The above is the outline of the configuration of the present invention. As for the positional relationship of each part, as shown in the drawings, the ampoule 2 is fitted into or stored in the ampoule receiver 4, and the syringe 6 and the syringe receiver 7 are inserted from the other side. When the ear 10 protruding from the end of the syringe barrel 9 hits the end 11 of the main body 1 or the syringe receiver 7, the needle tip 8 of the syringe is a rubber on the head of the ampoule 2. It should be possible to insert about 2 to 3 mm into the inside of the portion 3.

A unit measuring plate 14 for measuring the amount of insulin inhaled in the syringe by applying it between the ear portion 10 of the injection cylinder 9 and the pushing plate 13 of the piston shaft 12 is separately prepared. The unit quantity measuring plate 14 has a unit quantity number 15 for insulin inoculation written on the plate surface in a large number, and a predetermined liquid quantity is suctioned and determined by its width.

[Operation] In use, first, the rubber portion 3 of the ampoule 2 of insulin is sterilized, and then the ampoule 2 is fitted or stored in a fixed position of the ampoule receiver 4 of the auxiliary device body 1 by using the clasp 5 or the like.

Next, the piston shaft is pulled out by the pushing plate 13 of the syringe 6 while applying the unit amount measuring plate 14, and the air amount corresponding to the unit amount of insulin instructed by the doctor is inhaled into the injection cylinder 9.

Place the syringe 6 that has inhaled the air on the syringe receiver 7,
Insert the needle tip 8 toward the rubber portion 3 of the ampoule 2 while sliding.

Then, the ear portion 10 of the syringe barrel 9 causes the distal end 11 of the syringe receiver 7 to move.
At the touched position, the needle tip enters and stops at an appropriate position in the rubber portion 3 of the ampoule 2.

Then, the piston shaft 12 is pushed to inject the air in the injection cylinder 9 into the ampoule, the piston shaft 12 is pulled out again, and the unit amount measuring plate 14 is applied to measure the necessary amount of insulin after inhalation into the injection cylinder 9. The plate 14 is removed. The ampoule 2 described above is rotated, for example, when the rubber part 3 is sterilized and detached so that the label position is turned up, down, or right. Four
Therefore, the needle tip 8 is not inserted into a specific portion of the rubber portion 3 in a concentrated manner due to the displacement of the shaft center between the ampoule 2 and the syringe 6.

By the above operation, the insulin injection solution can be accurately inhaled into the syringe without depending on the scale of the injection cylinder 9, and then the self injection operation is performed according to a predetermined method.

[Example] Next, an example in which the syringe receiver 7 is slightly modified will be described with reference to FIG.

Regarding the syringe receiver 7, in FIG. 1, two short receivers are shown as a guide for the placement slide of the syringe 6, but this is one receiver regardless of the two. Although it may be configured, here, as an example thereof, a type in which the gap is divided into two and used for attaching and detaching the cap 16 of the syringe 6 will be described.

The syringe receiver 7 of the present invention is divided into a short portion on the side of the ampoule and a long portion on the side of the ear portion 10 of the syringe 6 to form 7 and 7 ', and the gap therebetween serves as a cap collar groove 17.

The cap collar insertion groove 17 is for engaging and disengaging the cap 16 of the syringe 6 by hooking the collar 18 of the cap 16.

[Effects of the Invention] As can be seen from the above, according to the present invention, even a visually impaired person who cannot read fine scales or numbers can be blind if the unit quantity number 15 is displayed in Braille. Also, the drug solution can be safely and reliably inhaled into the syringe during self-injection of insulin.

Further, in the present invention, since the shaft center of the ampoule 2 and the shaft center of the syringe 6 are slightly displaced from each other, the needle tip 8 of the syringe 6 is inserted into a part of the head of the ampoule 2 slightly displaced from the center of the rubber part 3. Be done. Therefore, the insertion mark of the needle tip 8 into the rubber portion 3 theoretically becomes a circular shape with the deviation of the shaft center of the ampoule 2 as a radius by repeating the attachment and detachment of the ampoule 2 and the like. It becomes a ring shape with a width.

From this, it is possible to completely prevent the possibility that the rubber tip 3 is mechanically pierced by the needle tip 8 at a specific location of the rubber portion 3 and the rubber portion 3 is damaged.

Next, the embodiment has the effect of facilitating the attachment / detachment of the cap 16 of the syringe 6 before and after the operation for inhaling the liquid medicine of the syringe 6. That is, when the syringe 6 with the cap 16 still attached is slid toward the ampoule 2 along the groove of the syringe receiver 7 ′, the cap mounted so as to slightly project from the side surface of the syringe barrel 9. The collar 18 of 16 is fitted in the cap collar groove 17 provided between the injection receptacles 7 and 7'and the sliding of the syringe 6 is stopped, and when the syringe 6 is returned to the original direction, the cap 16 comes off. . Similarly, when the cap 16 is mounted, the collar 18 of the cap 16 is aligned with the cap collar insertion groove 17, and then the syringe 6 is slid along the groove of the syringe receiver 7'to ensure the safety and accuracy of the cap 1
The installation of 6 is completed.

In particular, it is expected that the latter cap 16 will be greatly welcomed since it is easy for the visually impaired person to have difficulty and has had many accidents.
