Medical waste sealing bag
Abstract
A medical waste sealing bag having an opening and at least one
via holes at predetermined positions; high efficiency filtering
material being attached on the via hole and in an inner side of the
sealing bag. The high efficiency filtering material is selected
from HEPA high efficiency particulate air filer or ULPA ultra-low
penetration air filter. The sealing of the sealing bag to the high
efficiency filtering material is achieved by heat pressure sealing
edges or glue on. A predetermined position of the sealing bag is
cut with a via hole. The high efficiency filtering material
contains a layer of activate carbon filtering material.

Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to sealing bags, and
particularly to a medical waste sealing bag, wherein the medical
waste sealing bag has an opening and at least one via holes at
predetermined positions; high efficiency filtering material being
attached on the via hole and in an inner side of the sealing
bag.
[0003] (b) Description of the Prior Art
[0004] In the prior art medical waste sealing bag, medical wastes
are placed in the bags and then the bags are discarded. In general,
air, particles, viruses, etc. possibly leak out so as to pollute
the environment, even to induce diseases. Air in the bags will
expand the volume of the bags. If it is desired to vent air in the
bags, it will induce the harmful objects in the bags to leak out.
Thereby, there is a demand for a novel design which can improve
above mentioned defects.
SUMMARY OF THE INVENTION
[0005] Accordingly, the primary object of the present invention is
to provide a medical waste sealing bag having an opening and at
least one via holes at predetermined positions; high efficiency
filtering material being attached on the via hole and in an inner
side of the sealing bag. The high efficiency filtering material is
selected from HEPA high efficiency particulate air filer or ULPA
ultra-low penetration air filter. The sealing of the bag body to
the high efficiency filtering material is achieved by heat bonding
or glue. A via hole is cut at a predetermined position on the
sealing bag. The high efficiency filtering material contains a
layer of activate carbon filtering material.
[0006] The various objects and advantages of the present invention
will be more readily understood from the following detailed
description when read in conjunction with the appended drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is an assembled perspective view of the present
invention,
[0008] FIG. 2 is an exploded schematic view of the present
invention.
[0009] FIG. 3 is a schematic view showing the operation of the air
venting in the present invention.
[0010] FIG. 4 is a schematic view showing the via holes of the bag
are closed.
[0011] FIG. 5 shows one embodiment of the present invention, where
the sealing bag is formed with a plurality of via holes.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] In order that those skilled in the art can further
understand the present invention, a description will be described
in the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0013] With reference to FIGS. 1, and 2, the medical waste sealing
bag of the present invention is illustrated. The medical waste
sealing bag includes an opening 11 which is installed with at least
one sealing fixing element 111 formed by flexible strips.
[0014] The sealing bag I has at least one via hole 12 at a
predetermined position. High efficiency filtering material 2 is
attached on the via hole and in the inner side of the bag. Air in
the bag can be drained by high efficiency filtering material 2 so
as to reduce the air volume of the bag. Particles and viruses are
isolated by the high efficiency filtering material 2 so as to be
left in the bag to prevent from diffusion to pollute the
environment.
[0015] The high efficiency filtering material 2 is selected from
HEPA high efficiency particulate air filer or ULPA ultra-low
penetration air filter, and so on. The efficiency of high
efficiency filtering material can achieve a value of 95% for
filtering particles and viruses.
[0016] The sealing of the sealing bag 1 or the via hole 12 to the
high efficiency filtering material 2 is achieved by heat pressure
sealing edges or glue on. After the opening 11 of the sealing bag 1
is sealed with the retaining element 111, the residual air in the
bag only filters through the high efficiency filtering material 2
to drain out (referring to FIG. 3) so that particles and viruses
are left in the bag. Thereby, the present invention is suitable for
medial, nuclear, biological, and chemical wastes.
[0017] In the present invention, the sealing bag 1 is cut to form
an opening so as to form a via hole 12 so that that after air stops
to release out, the via hole 12 will close automatically (referring
to FIG. 4).
[0018] Referring to FIG. 5, in use of the present invention, a
plurality of via holes 12 are formed near the opening 11 of the bag
1. The high efficiency filtering material 2 are placed within the
via holes 12. Moreover, a layer of activate carbon filtering
material can be added for deleting undesired odor.
[0019] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
