Abstract
Abstract An extractable device is used to insert a medicinal filling into an animal tissue. The device comprises a filling member and a pasty medicine. The filling member is made of a flexible and permeable wall and is provided with a holding portion and an injection port via which the pasty medicine is injected into the holding portion after the filling member is inserted into the animal tissue. The holding portion is provided with an opening which is releasably lashed by one end of one or more threads so as to make the opening leakproof. Upon completion of solidification of the pasty medicine in the holding portion of the filling member, other end of the thread is pulled to unlash the opening of the holding portion, thereby enabling the filling member to be extracted from the animal tissue so as to leave only the medicine in the animal tissue.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
169 words
An extractable device for inserting a medicinal filling into an
animal tissue, said device comprising: a filling member comprising a flexible and permeable wall and
provided with a holding portion, an injection port at one end of the holding
portion, and an opening at another end of the holding portion; one or more thread, each having one end for fastening
releasably said opening of said holding portion in such a manner that said
opening is leakproof; and a pasty medicine to be injected into said holding portion via said
injection port of said filling member in the wake of a process for inserting
said filling member into the animal tissue whereby said pasty medicine
solidifies in said holding portion of said filling member; said opening of said holding portion being unfastened at the time
when other end of said threads is pulled by an external force, thereby
enabling said filling member to be extracted from the animal tissue so as
to leave only said medicine in the animal tissue.
Claim 2
Dependent Claim
20 words
The device as defined in claim 1, wherein said flexible and
permeable wall is of a one-layered or multi-layered construction.
Claim 3
Dependent Claim
35 words
The device as defined in claim 1, wherein said holding portion
of said filling member is integrally formed by said flexible and permeable
wall into a body in the form of sac, bag, or ball.
Claim 4
Dependent Claim
26 words
The device as defined in claim 1, wherein said pasty medicine
is a mixture of a liquid and a medicinal powdered substance or medicinal
granular substance.
Claim 5
Dependent Claim
25 words
The device as defined in claim 1 further comprising an
injection tool for injecting said pasty medicine into said holding portion via
said injection port.
Claim 6
Dependent Claim
83 words
The device as defined in claim 5, wherein said injection tool
comprises a guide tube and a syringe, wherein one end of said guide tube
is connected to said injection port of said filling member and another end
of said guide tube is connected to said syringe in which said pasty
medicine is held, so that said pasty medicine is able to be injected into
said holding portion of said filling member by said syringe via said
injection port and said guide tube.
Claim 7
Dependent Claim
91 words
The device as defined in claim 1, wherein said flexible and
permeable wall is a double-layer tubular wall having one end of an inner
layer thereof being provided with said injection port of said holding portion,
and having another end thereof being a folded double-layer end with said
opening of said holding portion, wherein said medicine is released from
said filling member by pulling a free end of an outer layer of the
double-layer tubular wall to retreat the folded double-layer end, after said
opening of said holding portion being unfastened.
Claim 8
Dependent Claim
27 words
The device as defined in claim 7, wherein said one or more
thread is between said inner layer and said outer layer of said
double-layer tubular wall.
Claim 9
Dependent Claim
91 words
The device as defined in claim 6, wherein said flexible and
permeable wall is a double-layer tubular wall having one end of an inner
layer thereof being provided with said injection port of said holding portion,
and having another end thereof being a folded double-layer end with said
opening of said holding portion, wherein said medicine is released from
said filling member by pulling a free end of an outer layer of the
double-layer tubular wall to retreat the folded double-layer end, after said
opening of said holding portion being unfastened.
Claim 10
Dependent Claim
27 words
The device as defined in claim 9, wherein said one or more
thread is between said inner layer and said outer layer of said
double-layer tubular wall.
Claim 11
Dependent Claim
162 words
An extractable device for inserting a medicinal filling into an
animal tissue, said device comprising: a filling member comprising a flexible and permeable wall which
is formed of a plurality of threads by weaving, said filling member provided
with a holding portion and an injection port at one end of the holding
portion, said threads having a pull end extending out of said filling
member; and a pasty medicine to be injected into said holding portion via said
injection port of said filling member in the wake of a process for inserting
said filling member into the animal tissue whereby said pasty medicine
solidifies in said holding portion of said filling member; said flexible and permeable wall of said filling member being
disintegrated at the time when the pull end of said threads is pulled by an
external force, thereby enabling said filling member to be extracted from
the animal tissue so as to leave only said medicine in the animal tissue.
Claim 12
Dependent Claim
