Description

  The present invention relates to a small container used when injecting a fluid into a medical instrument or the like.

  When an internal examination or treatment is performed using an endoscope, a drug such as a hemostatic agent may be administered to the affected area during the examination or the like. The drug is administered by connecting the extraction portion of the container containing the drug to the forceps port of the endoscope and injecting the same into the endoscope. In general, a syringe for injection has been used as a container for administering a drug using an endoscope, but from the viewpoint of preventing misidentification with a syringe and the cost of the syringe being high and uneconomical, In recent years, a small container having a pouring part provided on a container body made of a film material has been proposed, which is disclosed in Patent Document 1 below.

  As shown in FIG. 9A, the small container disclosed in Patent Document 1 is a discharge channel that communicates with the storage chamber 101 in a flexible container body 102 provided with a sealed storage chamber 101. The tubular extraction part 104 in which 104p was formed is connected and comprised.

  The container body 102 of the small container 100 has upper and lower film materials F1 and F2 (FIG. 9 shows a cross section of the small container 100, so the film material F1 on the front side of the paper is not shown) circulates around the outer periphery thereof. As described above, the side edges 102c and 102d and the bottom edge 102b are joined to each other to form a flat shape with a small thickness. As a material of the container main body 102, a flexible synthetic resin that can be deformed by the gripping force of the user is used.

  The pouring part 104 accommodates a closing part 105 integrally formed to seal the discharge flow path 104p on the base end side, and operation protrusions 106a and 106b provided continuously to the closing part 105. It is provided in the chamber 101.

The operation protrusions 106a and 106b are formed of protrusions extending in a direction away from the extraction part 104 toward the storage chamber 101, and are made of a resin material.
Further, the connecting portion 108 formed between the dispensing portion 104 and the operation projections 106a and 106b is formed to be ruptureable by relatively mutating the operation projection portions 106a and 106b.
The leading end of the dispensing portion 104 is closed with a peelable seal material 107. The storage chamber 101 is filled with a medicine such as a liquid or a semi-liquid.

In order to inject a drug from the small container 100 into the forceps opening and administer it to the affected area, as shown in FIG. 9B, first, after removing and removing the sealing material (not shown), the forceps of the endoscope 109 The tip of the pouring part 104 is inserted and arranged in the mouth 110, the container main body 102 is gripped and the operation protrusions 106a and 106b are relatively displaced so as to be close to each other, and the connecting part 108 is broken.
When the connecting portion 108 is broken, the storage chamber 101 and the discharge flow path 104p of the extraction portion 104 communicate with each other. Therefore, the container body 102 is further compressed, and the medicine in the storage chamber 101 is pushed out to the extraction portion 104 to forceps. It is supplied to the mouth 110 and administered to the affected part from the distal end of the endoscope 109.
When the administration of the medicine is completed, the extraction unit 104 is extracted from the forceps port 110.

The dimensions of the container body 2 are such dimensions that can be grasped with one hand, the width dimension is about 2 cm to 12 cm, and the height dimension is about 2 cm to 12 cm. The container body 2 is made of a flexible film material, and a synthetic resin, specifically, for example, polyolefin is preferably used as the material.
In this configuration, the space portion X of the container body 2 is a three-dimensional space that expands in the horizontal direction and the vertical direction.

The pouring member 4 is a tubular member that allows the space portion X of the container body 2 to communicate with the outside, and is inserted between the wall portions 12 and 14 at the center in the width direction of the front end portion 3, and is in close contact with them. Is retained.
As shown in FIG. 4, the dispensing member 4 is formed so as to communicate with the base portion 21 in which the inner hole 20 has a large diameter and the inner hole 20 of the base portion 21, and has a smaller diameter than the inner hole 20. An insertion portion 23 having an inner hole 22 is formed. Furthermore, the distal end portion 24 of the insertion portion 23 is formed such that the inner hole 25 gradually becomes smaller in diameter toward the opening end surface 25a of the most distal end portion.

  In this case, the inner hole of the pouring member 4 is formed to have a circular cross section from the inner hole 20 to the tip of the inner hole 25. The inner hole 25 of the distal end portion 24 is preferably formed to have a diameter of φ2 mm to 0.3 mm at the opening end surface 25a.

A lid body 26 that seals the inner hole 25 of the extraction member 4 is formed at the distal end portion 24 of the extraction member 4.
The lid body 26 is a bowl-shaped body having a length that can be grasped by hand, and is formed with bulging portions 26A, 26B, 26C,. Is formed with a bulging portion 26D having an outer shape in which a part of the abacus-shaped bulging portion is cut out.

The base end surface 26c of the base end portion 26b of the lid 26 has a larger diameter than the inner hole 25 in the opening end surface 25a of the pouring member 4 and covers the entire inner hole 25, and the pouring member In order to be easily separated from the distal end of 4, the shape is gradually recessed toward the base end face 26c.

Next, a method for manufacturing the small container 1A will be described.
With the front end of the opening of the film material formed of a tubular film made of inflation film or the like being opened, the pouring member 4 is arranged at the center as shown in FIG. 1, and the front end 3 and the vicinity of both sides thereof are melted. A first seal portion is attached. At this time, the surface including the surface formed by the first seal portion becomes the reference surface P shown in FIG.

  As a result, the front end 3 side of the container body 2 is completely sealed. In this state, the rear end 5 is positioned so as to face upward, and a fluid such as a medicine is injected from the opening. On the reference surface Q obtained by rotating the reference surface P on which the first seal portion 6 is formed by 90 degrees with respect to the axis of the extraction member 4, the rear end portion 5 side is sealed and the second seal portion 7 is sealed. As a result, a small container 1A holding a fluid is formed.

At this time, the second seal portion 7 is formed in a “<” shape that is recessed in the direction of the front end portion 3 of the container body 2 at the rear end portion 5 at a position substantially corresponding to the center in the length direction of the second seal portion 7. It is heat-sealed to become.

To do. The injected medicine is administered to the affected part through the endoscope 30. When administration of the medicine accommodated in the container body 2 of the small container 1A is completed, the dispensing member 4 is extracted from the forceps port 31 and the small container 1A is discarded.

  According to the small container 1A, the opening of the tubular film material is sealed by the first seal portion 6 and the second seal portion 7 so as to extend in the horizontal direction and the vertical direction. Since the space portion X is formed to be three-dimensional, an effect that a space for encapsulating a drug can be sufficiently secured is obtained.

  In addition, since the small container 1A can be manufactured only by sealing the film material only by the film material and the dispensing member 4, the structure is simple and easy to manufacture, the manufacturing cost is reduced, and it is also suitable for disposable use. The effect is obtained.

  In addition, since the three-dimensional space is formed by sealing, when the opening is sealed after putting the fluid in the space X, the container body 2 becomes flat and overflows the fluid. The effect that it can be avoided is obtained.

  Further, as shown in FIG. 4, the bulging portion 26D at the tip of the lid body 26 is formed to have a larger cross-sectional diameter than the outer diameter of the insertion portion 23 of the pouring member 4, so that the lid body 26 is It is impossible to insert the insertion portion 23 into the forceps port 31 without removing it. Therefore, the infusion member 4 is inserted into the forceps port 31 with the lid 26 being crowned, and even if the container body 2 is grasped, the medicine is not administered, so that the inconvenience of interrupting the inspection or the like can be avoided. The effect that the misuse which breaks the mirror 30 can be prevented is acquired.

  Moreover, since the diameter dimension of the inner hole 25 of the front-end | tip part 24 of the extraction | pouring member 4 is made gradually small diameter, it can avoid discharging | emitting a chemical | medical agent carelessly and it dispenses, adjusting discharge amount. The effect that it can be obtained.

  In the present embodiment, the second seal portion 7 is formed by heat-sealing in a strip shape on the reference plane Q passing through the axis of the tubular pouring member 4 and orthogonal to the reference plane P. As long as it is on a plane that passes through the axis of the tubular extraction member 4 and forms an angle with the reference plane P, it may not be formed on the orthogonal reference plane Q.

  Synthetic resins used for the film material and the pouring member 4 constituting the container body 2 include polyolefins such as polyethylene, polypropylene and cyclic polyolefin, polyethersulfone, polyamide, polyester, ethylene-vinyl alcohol copolymer and mixtures thereof.

Furthermore, vapor deposition films, such as a vapor deposition polyester film and a vapor deposition polyamide film, aluminum foil, etc. can also be used as a film which comprises a film material.

  The film material and the dispensing member 4 constituting the container main body 2 can have a single layer structure or a multilayer structure, respectively, depending on the type of drug. For example, the wetted parts are all annular by combining a multilayer film material having a film made of cyclic polyolefin on the innermost layer that becomes the inner wall surface of the container body 2 and a pouring member 4 made of a single layer of cyclic polyolefin. It becomes polyolefin resin and the effect that it can prevent that the active ingredient of a medicine adsorb | sucks to the small container 1A and a medicinal effect falls is acquired.

  As another example, the film material is a multilayer film of three or more layers having an inner layer, an intermediate layer and an outer layer, and the intermediate layer is a film made of an ethylene-vinyl alcohol copolymer, polyamide and polyester, a vapor deposition film and an aluminum foil. By adopting a structure in which a film having a barrier property such as that is sandwiched, an effect of preventing alteration of a drug due to oxygen or light can be obtained.

  Moreover, since the extraction | pouring member 4 is inserted between wall part 12 and 14 by the front-end part 3 of the container main body 2, and is closely_contact | adhered and hold | maintained, the innermost surface of the container main body 2 and the extraction member 4 is preferably a combination of synthetic resins that can be thermally bonded to the outermost surface, and more preferably the same synthetic resin.

Moreover, in said embodiment, although the inner hole of the extraction | pouring member 4 is made into the cross-sectional regular circle, it is good also as a horizontally long slit shape.
By making the inner hole of the dispensing member 4 into a horizontally long slit shape, the medicine is not easily discharged from the dispensing member 4 even if the lid body 26 is separated and the dispensing member 4 is opened to tilt the small container 1A. In the case of handling the small container 1A at the side of treatment, or during the operation of inserting the small container 1A into the injection port such as the forceps port 31, the liquid does not easily spill unless the container is intentionally compressed. The effect that it is possible to prevent the medicine from being discharged in advance is obtained.
The same effect as described above can also be obtained by setting the diameter of the inner hole 25 in the opening end surface 25a of the dispensing member 4 to 2 mm to 0.3 mm.
