DESCRIPTION:
BRIEF SUMMARY
This invention relates to a bellows type container charged with liquid medicine.
There is in a part of a liquid transfusion set a bellows type container charged with liquid medicine (for example, physiological saline, grape sugar, antibiotic substance, calmative, analgesic, heparin, nitroglycerin solution and the like).
Heretofore, since such a kind of container is provided with only an outlet for liquid medicine on its one end, its object of use was limited.
On the other hand, there has been a continuous injector for liquid medicine (Japanese Patent No. 1384289) developed by the present applicant. This injector includes an inlet portion for liquid medicine, an outlet portion for liquid medicine, and a balloon which connects the inlet portion to the outlet portion. Liquid medicine injected in the balloon flows out through the outlet portion for a long period of time.
However, this continuous injector for liquid medicine requires an additional injector for injecting liquid medicine into the balloon of the former injector. This operation is troublesome and maintenance of a pair of injectors is inconvenient. Thus, the present applicant has proposed "a continuous injector for liquid medicine with a bellows type container" (Japanese Utility Model Publication No. 6-7722 (1994)), in which the continuous injector for liquid medicine is effectively united to a conventional bellows type container charged with liquid medicine.
However, in this injector, in the case of using only the container, handling of the container is difficult on account of the obstructive injector.
An object of the present invention is to provide a bellows type container charged with liquid medicine which can be used as usual a conventional liquid medicine container and a special tool such as a continuous injector for liquid medicine.
In a bellows type container charged with liquid medicine, a bellows type body is provided at one end with an outlet portion for liquid medicine and at its other end with a one-way valve and a foldable hook. The liquid medicine is injected into and ejected from the bellows type body through the one-way valve.
In the bellows type container charged with liquid medicine in accordance with the present invention, under a normal use the hook is hung on a support table and a needle for ejecting the liquid medicine and a needle for communicating with the atmosphere are pierced through the outlet portion to eject the liquid medicine.
Under a special use for a special tool such as the continuous injector for liquid medicine, the one-way valve is connected to an inlet portion of the special tool and the liquid medicine in the container is flowed into the special tool by compressing a bellows type body. When compression of the bellows type body is interrupted, the body maintains its compressed state.
FIG. 1 is a longitudinal sectional view of a bellows type container charged with liquid medicine in accordance with the present invention;
FIG. 2 is a front elevational view taken along lines II--II in FIG. 1;
FIG. 3 is an explanatory view of coupling constructions; and
FIG. 4 is an explanatory view of an example of utilizing the container of the present invention.
Embodiments of a bellows type container charged with liquid medicine in accordance with the present invention will be explained below by referring to FIGS. 1 to 4.
As shown in FIGS. 1 and 2, in the bellows type container 1 charged with liquid medicine of the present invention a bellows type body 11 is provided on its one end with an outlet portion 12 for liquid medicine and its other end with a one-way valve 13 and a foldable hook 14. On the other hand, liquid medicine can be injected into and ejected from the body 11 through the one-way valve 13.
The bellows type body 11 is made of a flexible material (for example, polyethylene, polypropylene or the like). A given liquid medicine is injected in the container 1.
The outlet portion 12 for liquid medicine is integrally formed with the body 11 or made of synthetic rubber or the like independent on the body 11.
