Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an enema container into which a nozzle can be easily inserted deeply.

[0002]

2. Description of the Related Art An enema drug solution is used in a special enema container.

A conventional enema container is formed by attaching a nozzle to an upper portion of a container body via a bellows. Therefore, this device has a container body, and can insert a nozzle into an anus to inject a drug solution, and the nozzle can be inclined at an appropriate insertion angle through a bellows.

[0004]

According to such a conventional technique, the nozzle can be tilted through a bellows, but since the nozzle itself remains in a straight rod shape, when inserted deeply, the inner wall of the rectum is damaged. There is a problem that there is a possibility that it will be lost.

Accordingly, an object of the present invention is to provide an enema which can be easily inserted deep into the rectum without damaging the inner wall of the rectum by forming a deformable portion which is easily curved in the nozzle in view of the problems of the prior art. It is to provide a container.

[0006]

In order to achieve the above object, according to the present invention, a bellows and a nozzle are formed integrally with a push-deformable container body, and the nozzle has a deformable portion which is easily curved. Forming is the gist.

The deformed portion can be formed to have an elliptical cross section, and the nozzle can be formed by smoothly reducing the diameter in the short axis direction.

[0008] The deformed portion may have the major axis direction and the minor axis direction coincide with the container body having an elliptical cross section.

When a lateral force is applied to the tip of the nozzle, the nozzle may tilt through the bellows and then bend through the deformed portion, and the bellows may define the insertion limit of the nozzle. .

[0010]

According to the structure of the present invention, since the nozzle is formed integrally with the container body together with the bellows and has a deformed portion, when the nozzle is inserted into the anus, the nozzle is inclined at an appropriate insertion angle through the bellows and deformed. Through the portion, it curves along the sacrum in the rectum, so that it can be easily inserted deep into the rectum without damaging the inner wall of the rectum. The container body, the bellows, and the nozzle are integrally formed from a synthetic resin material having appropriate flexibility and chemical resistance, for example, low-density polyethylene.

The deformed portion having an elliptical cross section is more likely to bend in the minor axis direction than in the major axis direction, and the direction of the curvature can be limited to the minor axis direction.

The deformed portion does not form a harmful step on the outer surface by smoothly reducing the diameter of the nozzle in the short axis direction.

The deformed portion is limited in the bending direction to the short axis direction of the container body by making the long axis direction and the short axis direction of the container body coincide with each other, so that the insertion operation by the patient himself can be further facilitated.

[0014] After the nozzle is tilted through the bellows, it can bend through the deformed portion. That is, the bellows
By making the deformed portion more elastically deformable, the nozzle can be easily tilted to an appropriate insertion angle during insertion.

The bellows prevents the nozzle from being inserted too deep by defining the insertion limit of the nozzle. Note that the bellows at this time may have a diameter of the upper surface sufficiently larger than the outer diameter of the nozzle.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

The enema container is a container body 11 that can be pushed and deformed.
The bellows 12 and the nozzle 21 are integrally formed (FIG. 1,
(Fig. 2).

The container body 11, bellows 12, and nozzle 21
It is integrally molded from a synthetic resin material having flexibility and chemical resistance, for example, by blow molding. The container body 11
It is formed in an elliptical cross section, and a large-diameter bellows 12
Are formed. The container body 11 and the bellows 12 are
It is formed to be thin and elastically deformable.

The nozzle 21 projects from the center of the upper surface of the bellows 12. The nozzle 21 is formed in a cylindrical shape having an outer diameter D1 sufficiently smaller than the diameter D of the upper surface of the bellows 12, and a nozzle hole 21a is formed at the tip. The nozzle 21 is
A deformed portion 21b having an elliptical cross section is formed on the bellows 12 side, and smoothly continues to the upper surface of the bellows 12 below the deformed portion 21b.

The nozzle 21 has a deformed portion 21b
The outer diameter D1 in the minor axis direction changes smoothly in the axial direction (FIG. 3). That is, the deformed portion 21b smoothly reduces the diameter of the nozzle 21 in the short-axis direction so as not to form a harmful step on the outer surface of the nozzle 21, and matches the long-axis direction and the short-axis direction with the container body 11. . However, in FIG. 3, the nozzle 21 is schematically illustrated with an extremely large outer diameter D1 in the short axis direction. The minimum diameter D2 in the minor axis direction of the deformed portion 21b is preferably set to about 0.75D1≤D2≤0.9D1.

The nozzle 21 can be tilted by an angle θ1 via the bellows 12 by applying a lateral force F to the tip (solid line in FIG. 4), and then bend by an angle θ2 via a deformed portion 21b. Yes (two-dot chain line in the figure). However,
The deformed portion 21b at this time is smoothly curved as a whole,
It shall not cause substantial collapse. Note that the angle θ1,
θ2 is preferably set to about 30 ° and about 15 ° at the maximum, and the force F at that time is, for example, about 5 °.
It is good to set to 0 g and about 100 g.

In the enema container, a medical solution is stored in the container body 11, and a cap (not shown) is attached to the nozzle 21 for storage. When using the enema container, the cap is removed and the nozzle 21 is inserted into the anus of the patient P (FIG. 5). In addition, the patient P can insert the nozzle 21 into his / her anus by turning the short axis direction of the container body 11 up and down. At this time, the nozzle 21 is inclined at an appropriate insertion angle via the bellows 12,
In the rectum, it can be inserted deeply while bending along the sacrum P1 via the deformed portion 21b.
The bellows 12 abuts on the entrance of the anus, and the nozzle 2
Specifies the insertion limit of 1. Therefore, the container body 11 may be pushed and deformed in the short axis direction (the direction of the arrow in FIG. 5), and the chemical solution may be injected from the nozzle 21.

[0023]

As described above, according to the present invention, by providing the nozzle with a deformable portion which is easily curved, the nozzle is curved through the deformed portion and smoothly inserted into the rectum along the sacrum. Therefore, there is an excellent effect that the rectum can be easily inserted deeply without damaging the inner wall of the rectum.
