Means for Solving the Problems and Actions / Effects The present invention provides a syringe housing case having the following structure in order to solve the above technical problems.

The syringe storage case is of a type that stores at least a syringe. A needle unit accommodating a double-needle needle in a syringe storage case is provided at an end of the syringe, and an injection needle unit hole through which the base end side of the injection needle can be inserted in a non-rotatable manner with the base end exposed upward. Either one or both of the rotation operation dial holes into which the rotation operation dial can be inserted so as not to rotate freely are provided.

In the above configuration, the injection needle unit hole is
It is used for the operation of attaching and detaching the injection needle to and from the syringe. When attaching the injection needle, the needle unit is inserted into the injection needle unit hole of the syringe storage case, and is held with the base end side of the injection needle exposed upward. Then, while holding the syringe storage case with one hand, turn the needle mounting portion of the syringe with the other hand close to the needle unit. Since the injection needle unit is engaged with the injection needle unit hole and does not rotate, the injection needle is attached to the syringe by the relative rotation between the injection needle unit and the syringe.
When removing the injection needle, the syringe may be rotated in the opposite direction.

The rotary operation dial hole is used for setting a dose.
Used for rotating operation on syringe. That is, hold the syringe storage case with one hand, hold the syringe with the other hand, insert the rotation dial of the syringe into the rotation dial hole of the syringe storage case, and turn it. Since the rotary operation dial engages with the rotary operation dial hole and does not rotate, the syringe body and the rotary operation dial rotate relative to each other. Thus, the rotary operation dial can be turned.

According to the above configuration, a relatively simple operation of holding down the syringe housing case and turning the syringe while holding it can perform a rotating operation such as an attaching / detaching operation of the injection needle.
The fine operation of pinching and turning a small injection needle unit or a rotary operation dial with a fingertip is unnecessary.

Therefore, a rotating operation such as attaching and detaching the injection needle can be easily performed.

In the above configuration, the injection needle unit hole and / or the rotary operation dial hole can be provided at an appropriate position in the syringe housing case. For example, if it is provided on the bottom surface of the syringe storage case, it is necessary to turn the syringe storage case upside down when attaching the injection needle and / or when setting the dose. If a hole is formed in the opened portion of the syringe storage case, the injection When attaching the needle and / or setting the dose, etc., the hole of the syringe storage case will be used in the open state, but always keep the injection needle unit hole and / or rotary operation dial hole invisible. be able to.

Preferably, on the upper surface of the syringe storage case,
The injection needle unit hole and / or the rotary operation dial hole are provided.

According to the above configuration, when the injection needle is attached or the dose is set, the syringe storage case is closed, and the injection needle unit hole and / or the rotary dial hole are used without turning the syringe storage case upside down. And operation is easy.

[0020] Preferably, a non-slip member is provided on the back surface of the surface on which the injection needle unit hole and / or the rotary operation dial hole is formed.

In the above structure, a non-slip material such as rubber or sponge is used for the non-slip member. According to the above configuration, it is possible to hold the syringe housing case so as not to move with a small force, and to perform the operation of attaching / detaching the injection needle and / or the operation of setting the dose, and the operation is further facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a syringe storage case 10 according to one embodiment of the present invention will be described with reference to the drawings.

The syringe housing case 10 is configured substantially in the same manner as the conventional case, and the upper lid 12 opens and closes about the coupling portion 11 with respect to the case body 14.
The syringe storage case 10 can store the syringe 80, the injection needle unit 60, and the cartridge 70.

The upper lid 12 is different from the conventional one in that the upper surface of the upper lid 12 has an injection needle unit hole 1 into which the needle unit 60 is inserted.
2a and a rotary operation dial hole 12b into which the rotary operation dial 88 of the syringe 80 is inserted.

As shown in the perspective view of FIG. 6, when the needle unit 60 is inserted with its tapered side down, the conical portion 56a of the needle cover 56 is inserted into the needle unit hole 12a. The opening 57 is engaged with the hole 12a.
Is held in a state where the proximal end 50b of the injection needle 50 is exposed upward. Specifically, the conical portion 56a of the needle cover 56
Are formed at appropriate intervals in the circumferential direction, and the injection needle unit hole 12a is formed in a shape in which the unevenness is substantially transferred. That is, the groove 12s that engages with the projection 56s of the needle cover 56 is formed on the substantially conical inner peripheral surface.

As shown in the perspective view of FIG. 7, when the rotary operation dial 88 is inserted with the syringe 80 facing upward, the rotary operation dial 88 is engaged with the rotary operation dial hole 12b. Has become. More specifically, grooves 88t extending in the axial direction are formed at appropriate intervals in the circumferential direction on the substantially cylindrical outer peripheral surface of the rotary operation dial 88, and the rotary operation dial hole 12b substantially transfers this unevenness. It is formed in a shape. That is, the protrusion 12t that engages with the groove 88t of the rotary operation dial 88 is formed on the substantially cylindrical inner peripheral surface.

When attaching the injection needle 50 to the syringe 80, the upper lid 12 of the syringe storage case 10 is opened, the syringe 80 and the unused injection needle unit 60 are taken out from the inside, and the upper lid 12 is closed. Then, the tab 59a is pinched and the sterile seal 59 is peeled from the flange 58 of the injection needle unit 60, inserted into the injection needle unit hole 12a of the upper lid 12 of the storage case 10, the opening 57 faces upward, and the injection needle 5
In this state, the base end 50b of No. 0 is exposed.

Next, the storage case 10 is held down with one hand so as not to move, and the syringe 80 is held downward with the other hand. The syringe 80 is inserted into the inner screw of the needle holder 52 in 60, and the syringe 80 is turned in a predetermined direction. At this time, the streak-like projection 56s of the conical portion 56a of the needle cover 56 engages with the groove 12s of the injection needle unit hole 12a to prevent rotation. An external screw 85 of the syringe 80 can be screwed into the internal screw of the syringe 80. When completely screwed, the syringe 80 is lifted straight. As a result, the needle unit 60 is attached to the syringe 80. At the time of injection,
The needle cover 56 is removed from the syringe 80, the needle cap 54 is further removed, and the tip 50a side of the injection needle 50 is exposed and used.

After the injection, a needle cap 54 is attached to the injection needle 50, and a needle cover 56 is removed from the needle holder 52.
The injection needle 50 is removed from the syringe 80 in the reverse procedure to the above and collected. That is, while holding the syringe storage case 10 with one hand, holding the syringe 80 downward with the other hand, and keeping it straight, the needle cover 56 is inserted into the injection needle unit hole 12a of the syringe storage case 10 to attach. The syringe 80 is turned in the opposite direction, and the injection needle 50 is removed from the syringe 80 together with the needle cap 54 and the needle cover 56.

When operating the rotary operation dial 88 of the syringe 80, as shown in FIG. 7, the syringe holding case 10 is pressed with one hand (not shown), and the other hand (not shown).
While holding the syringe 80 downward and holding it vertically, insert the rotary operation dial 88 of the syringe 80 into the rotary operation dial hole 12b of the syringe storage case 10 and turn the syringe 80. At this time, since the protrusion 12t of the rotary operation dial hole 12b engages with the groove 88t of the rotary operation dial 88,
The rotary operation dial 88 does not rotate, and the main body side of the syringe 80 rotates with respect to the rotary operation dial 88. This allows the dosage unit to be set.

To make each of the above operations easier, a sheet made of a non-slip material such as rubber or sponge is attached to the back surface of the case body 14, and the syringe housing case 10 is moved with a little force. It is preferable to be able to hold it down.

As described above, the syringe storage case 1
If 0 is used, the fine operation of pinching and turning the small needle cover 56 or the rotation operation dial 88 with a fingertip becomes unnecessary. Therefore, if the syringe storage case 10 is used, the attachment / detachment operation of the injection needle 50 becomes easy, and the dose setting operation also becomes easy.

It should be noted that the present invention is not limited to the above embodiment, but can be embodied in various other modes.

For example, the first and rotary operation dial holes 12a and 12b are provided so that the needle cover 56 or the dial 88 is prevented from rotating when the needle cover 56 or the dial 88 is received.
8 can be formed in an appropriate shape. For example, the injection needle unit hole 12a may be shaped so as to engage with the projection 56x (see FIG. 6) of the cylindrical portion of the needle cover 56.

The first and rotary operation dial holes 12
Only one of a and 12b may be provided and used for only one of attachment / detachment of the injection needle 50 and setting of the dose. Furthermore, depending on the shape of the needle cover 56 and the rotary operation dial 88, even a single hole may be used.
It is also possible to use both for attaching and detaching the injection needle 50 and for setting the dose.
