Description

Disposable Liquid Ampoules {DISPOSABLE AMPULE FOR LIQUID}

The present invention relates to a disposable ampoule used for storing and dispensing liquids as needed.

In general, a point-of-care test (POCT) is an examination of the presence of a disease directly at the patient's site, including tests performed outside the hospital.

Areas where demand for on-site inspections is high are mainly developing countries with many infectious diseases and endemic diseases. This area has difficulty in diagnosing with the hospital kit because the storage condition of the diagnostic reagent for the field test is poor and the transportation means is out of order. Therefore, disposable containers are used as test reagent containers in diagnostic reagent kits to promptly diagnose communicable diseases without special medical staff in the area where medical facilities are not available.

However, due to the severe weather conditions, the inspection reagent stored in the disposable liquid container is evaporated through the container. Therefore, although the validity period of the diagnostic reagent has not passed two years, it is often inappropriate to use the diagnostic reagent for the test. In order to solve this problem, if the material of the container is changed, the user's operational inconvenience due to the material change must be solved.

It is an object of the present invention to provide a disposable liquid ampoule capable of minimizing a force required by a user in a squeegee operation for discharging the liquid although a material for preventing the evaporation of the stored liquid is employed.

Disclosed is a disposable liquid ampule according to one aspect of the present invention for realizing the above object. The disposable liquid ampule according to one aspect of the present invention includes a housing formed of high-density polyethylene having a space for accommodating a liquid and preventing the liquid from evaporating, A body having a neck connected to the body; And a closing member, connected to the neck, for blocking the discharge of the liquid through the neck, the housing having a base portion, an obtuse angle with the base, A reducing portion extending in an obtuse angle in an extending direction of the enlarging portion in the enlarging portion and having an outer width reduced in the first plane; Wherein the base portion, the enlargement portion, the reduction portion, and the non-reduction portion are each formed as a plane and are connected to each other to form a polygonal shape, wherein the base portion, the reduction portion, , The first bending point where the base portion and the enlargement portion meet is closer to the central axis of the housing than the second bending point where the enlargement portion and the reduction portion meet Wherein when the decreasing portion and the non-decreasing portion are squeegeared by the user's finger, the first bending point becomes a deformation supporting point and the second bending point is moved toward the central axis, and the non- 1 plane, and the inner width may be formed to be narrowed toward the neck.

Hereinafter, a disposable liquid ampoule according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

FIG. 1 is a perspective view of a disposable liquid ampoule 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along a second plane P2 with respect to the disposable liquid ampoule 100 of FIG.

Referring to these figures, a disposable liquid ampoule 100 may include a body 110, a closing member 130, and a gripping member 150.

The body 110 is a configuration for containing a liquid, specifically a liquid diagnostic reagent. The body 110 may have a housing 111 and a neck 117.

The housing 111 may be such that, in terms of material, the liquid is not evaporated. To this end, the housing 111 may be formed of high density polyethylene (HDPE). High density polyethylene is a synthetic resin produced by polymerizing ethylene, and the property is translucent solid. The inventor of the present invention has found that when the housing 111 has a density of 0.94 or more and a thickness of 0.5 mm or more as a high-density polyethylene material, the evaporation rate of the liquid in the housing 111 is minimized, (WHO) approval criteria.

The housing 111 may be formed such that the width along the second plane P2 is larger than the width along the first plane P1 in the structural plane. As a result, the housing 111 may have a flat shape substantially parallel to the second plane P2. Here, the first plane P1 and the second plane P2 may be planes intersecting with each other, specifically perpendicular to each other.

The housing 111 has a base portion 112, an enlarged portion 113, a reduced portion 114, and a non-enlarged portion 114 along the direction toward the neck 117 with respect to the first plane P1. Reduction part 115 may be sequentially arranged. In addition, the housing 111 may have a bag shape with a wide upper portion and a narrower lower portion with respect to the second plane P2. Specifically, the internal width of the accommodation space S on the second plane P2 increases in the enlarged portion 113, is constant in the reduced portion 114, and decreases in the non-reduced portion 115 do. With respect to these, the characteristics of the outer width and the inner width in the first plane P1 will be described in more detail with reference to Fig.

Referring again to the drawings, the neck 117 is a portion connected to the lower end of the housing 111. The neck 117 has a narrow width corresponding to the lower portion of the housing 111 with reference to both the first plane P1 and the second plane P2. The liquid in the accommodation space S of the housing 111 through the neck 117 can be discharged to the outside.

The closing member 130 is connected to the neck 117 to block the discharge of the liquid through the neck 117. The closing member 130 may have an injection rod 131 and an operation vane 135.

The injection rod 131 is configured to protrude from the neck 117. The injection rod 131 can communicate with the accommodation space S of the housing 111. [ For this purpose, the injection rod 131 may be a hollow pipe.

The operation wing 135 may extend outwardly from the injection rod 131 and have a plate shape. The operating vane 135 may be arranged to form the second plane P2. In addition, the operation vane 135 may have a shape in which the outer width decreases toward the housing 111.

The gripping member (150) is a structure to which the user holds the disposable liquid ampule (100). The gripping member 150 may be in the form of a plate connected to the body 110. Further, the gripping member 150 may be arranged to form the second plane P2, and may be flush with the operating vane 135.

The gripping member 150 may have a main portion 151 and a sub-portion 155. The main portion 151 may be a portion extending from the housing 111 to the opposite side of the closing member 130. The sub-part 155 may be connected to the main part 151 and may extend to cover both sides of the housing 111. Thereby, the width of the main portion 151 may be several times larger than the width of the sub portion 155 with reference to the second plane P2.

According to this configuration, the liquid can be charged into the accommodation space S of the housing 111 through the injection rod 131. [ After filling the liquid, the injection rod 131 may be deformed by thermal influence to shield the receiving space S (see the end 131 'of the modified injection rod, FIG. 4).

When the user wishes to discharge the liquid contained in the housing 111, the user grasps the operation wing 135 and twists it. Then, while the closing member 130 is separated from the neck 117, the liquid can be discharged to the outside.

Thereafter, when the user squeezes the housing 111 using the thumb and the index finger, the liquid can be dripped onto the object through the neck 117.

3 is a cross-sectional view taken along the first plane P1 with respect to the disposable liquid ampoule 100 of FIG.

Referring to this figure, the housing 111 can have a plurality of sections whose external width at the first plane P1 is variable as the direction of the neck N toward the neck 117 is changed.

Specifically, the base portion 112 has a shape extending on both lateral sides of the first plane Pl. Thereby, the base portion 112 can be formed in a plane substantially perpendicular to the main portion 151 of the gripping member 150.

The enlarged portion 113 extends from the base portion 112 and is extended in the first plane P1 toward the neck direction N. [ The portion where the enlarged portion 113 meets the base portion 112 is bent at a first angle, and the bending point is referred to as a first bending point 112 '. Here, the first angle may be an obtuse angle, for example, about 120 degrees.

The reduction portion 114 extends from the enlargement portion 113 and is a section in which the outer width at the first plane P1 is reduced toward the neck direction N. [ The portion where the reduction portion 114 meets the enlarged portion 113 is bent at a second angle, and the bending point is referred to as a second bending point 113 '. At this time, the second angle may be larger than the first angle. The second angle may, for example, be approximately 150 [deg.]. In addition, along the neck direction N, the length of the reduced portion 114 may be greater than the length of the enlarged portion 113. [ The section corresponding to the reduction section 114 in the accommodating space S has a shape in which the internal width is reduced toward the neck direction N similarly to the decreasing section 114 as in the section corresponding to the enlarging section 113 .

The non-reducing portion 115 extends in the reducing portion 114 and is a section in which the outer width at the first plane P1 is not reduced toward the neck direction N. [ In this embodiment, the non-reduced portions 115 are equal in outer width along the neck direction N. [ In addition, the non-reducing portion 115 forms a third angle with the reducing portion 114, and the third angle can be an angle of approximately 170 degrees. Unlike the outer width of the non-reduced portion 115, the inner width of the space corresponding to the non-reduced portion 115 of the accommodation space S is reduced toward the neck direction N. [

4 is a conceptual diagram showing a state in which a user scoops the disposable liquid ampoule 100 of FIG.

Referring to this figure, a user can grasp the housing 111 of the disposable liquid ampule 100 by using the thumb and the index finger F. Fig.

At this time, the arrangement structure between the reducing portion 114 and the non-reducing portion 115 allows the convex portion of the finger F to contact the reducing portion 114 and the non-reducing portion 115 over a large area.

As a result, the user can apply the force of the two fingers F as large as possible to the area of the housing 111, thereby pressing the housing 111 all over. This makes it possible to easily increase the discharge pressure for the liquid in the housing 111. As a result, the user can effectively squeegee the housing 111 without applying a large force.

5 is a cross-sectional view along a first plane P1 for explaining a deformation state of the disposable liquid ampoule 100 in the squeegee state of FIG.

Referring to this figure, when the force (SF) squeezed by the finger F (FIG. 4) is applied to the housing 111, the housing 111 is deformed as indicated by a dotted line. As a result, the enlarged portion 113, the reduced portion 114, and the both side walls of the non-reduced portion 115 approach toward each other. This is because most of the area of the housing 111 is gathered toward the center of the accommodation space S so that the liquid can be entirely pushed and moved to the injection rod 131 easily.

At this time, the second bending point 113 'is gathered toward the center of the receiving space S, but the first bending point 112' is almost kept in place. This first bending point 112 'serves as a deforming fulcrum which allows the enlarging portion 113, the reducing portion 114, and the non-reducing portion 115 to be deformed toward the center of the receiving space S . Further, the second bending point 113 'between the enlargement unit 113 and the reduction unit 114 can easily participate in the deformation unit 114 as well as the reduction unit 114.

The accommodation space S formed by the base portion 112, the enlargement portion 113, the reduction portion 114 and the non-reduction portion 115 has a structure of an inverted triangle, Which is suitable for applying a larger pressure to the liquid at the time of squeegeeing. The inverted triangular structure is also suitable for the liquid to gather toward the neck 117 by its own weight.

Furthermore, the third bending point 115 'of the non-reducing portion 115 may also serve as a deformation supporting point, similar to the first bending point 112'. The third bending point 115 'has the greatest thickness of the non-reducing portion 115, and thus plays a role of supporting the neck 117 even when the closing member 130 is twisted.

Such a disposable liquid ampoule is not limited to the construction and operation of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
