Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an inserter containing a hemostatic plug (tampon).

``Prior art'' As this type of inserter, the above-mentioned It is well known that the hemostatic plug is fitted so that it is pushed upward from the upper end of the main cylinder.

``Problem to be solved by the invention'' However, in the conventional inserter described above, the auxiliary tube is formed of a single tube with a sufficient length to completely push the hemostatic plug out of the main tube. Since the length remained unchanged, the package size became large, making it inconvenient to carry.

Therefore, the present invention aims to solve the above-mentioned problems by configuring the length of the auxiliary tube to be variable.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides an auxiliary cylinder 3 in the lower part of the main cylinder 1 in which the hemostatic plug 2 is housed.
In the inserter, the upper part of the auxiliary cylinder 3 is fitted so that the hemostatic plug is pushed upward from the upper end of the main cylinder by pushing the auxiliary cylinder into the main cylinder.
is formed of an outer cylinder 10 which forms an intermediate cylinder part with a folded bellows-like part 9, and an inner cylinder 11 that is loosely inserted into the outer cylinder and whose lower end is fixed to the lower end of the outer cylinder, and the bellows A first locking portion 13 is attached to the inner surface of the upper end of the shaped portion, and a second locking portion is locked to the first locking portion 13 when the bellows-shaped portion 9 is stretched by pulling down the lower end of the outer cylinder. 16 is attached to the upper end of the inner cylinder.

"Operation" For example, in the state shown in FIG. 1, the bellows-like portion 9 of the outer cylinder 10 is folded and the auxiliary cylinder 3 is in a contracted state.

When the lower end of the outer cylinder is pulled down from the above state and the bellows-shaped part is stretched, the inner cylinder 11
A second locking portion 16 at the upper end locks with a first locking portion 13 on the bellows-shaped portion of the outer cylinder.

This makes it impossible to fold the bellows-shaped portion again, and the auxiliary cylinder is held in an extended state with a length sufficient to push out the hemostatic plug 2.

"Embodiments" Examples of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 and 2, 1 is a main cylinder, 2 is a hemostatic plug (tampon) housed in the main cylinder 1, and 3 is an auxiliary cylinder for pushing out the hemostatic plug 2.

The main cylinder 1 includes a large-diameter cylinder part 4a and a small-diameter cylinder part 4b connected to the lower end of the large-diameter cylinder part 4a via an upward step 5.
The hemostatic plug 2 is housed in the large-diameter cylindrical portion 4a. Further, on the upper end surface of the large diameter cylindrical portion 4a, a plurality of elastic pieces 6a...
... forms a hemispherical top wall portion 6.

A removal string 8 is suspended from the lower end surface of the hemostatic plug 2, and the string 8 is inserted into the auxiliary tube 3.

The auxiliary cylinder 3 includes an outer cylinder 10 that forms an intermediate cylinder part with a folded bellows-like part 9, and an inner cylinder 11 that is loosely inserted into the outer cylinder 10 and whose lower end is fixed to the lower end of the outer cylinder. I'm letting you do it.

The upper part of the outer cylinder 10 is fitted into the small diameter cylinder part 4b so as to be able to move upward freely, and an outward flange part 12 is attached to the upper end of the outer cylinder, and the lower surface of the outward flange part 12 is in contact with the upward step portion 5. In other words, the outer cylinder is prevented from slipping downward. Further, a concave portion (trough) on the inner surface of the upper end of the bellows-shaped portion 9 is formed in the first locking portion 13 (see FIG. 2).

The lower part of the inner cylinder 11 is formed with a large outer diameter part 14, and the outer surface of the large outer diameter part 14 is fitted into the lower part of the outer cylinder. An outward flange 15 protruding from the outer cylinder is attached to the lower end of the large outer diameter. Further, the upper end of the inner cylinder is provided with a second locking part 16 that locks with the first locking part 13 when the bellows-shaped part 9 is stretched by pulling down the lower end of the outer cylinder. In the illustrated example, the second locking portion 16 is formed of an upper large-diameter skirt-like wall provided with a plurality of vertical slits.

Incidentally, in the above embodiment, each part except the hemostatic plug 2 is molded and manufactured from a synthetic resin material as appropriate.

``Effects of the invention'' As explained above, according to the invention, the length of the auxiliary tube for extruding the hemostatic plug is made variable so that the package can be made smaller, making it extremely convenient for carrying. .
