Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an infusion container. More specifically, the present invention relates to a drip container used for accurately dropping a necessary amount of liquid medicine such as a test reagent and an adhesive.

[Prior Art] A conventional drip container will be described with reference to Figs.

The drip container (I) of FIG. 4 is such that a screw cap (42) with a dropper (41) is screwed into a glass bottle (40). When using, remove the screw cap (42), take the liquid with a dropper (41), and drop a necessary amount on a sample or the like.

The drip container (II) shown in FIGS. 5 and 6 is a glass bottle (50) whose mouth is sealed with a rubber stopper (51) and covered with an aluminum cap (52). When using, remove the rubber stopper (51) and the cap (52) from the glass bottle (50) and take out the liquid with a pipette (53).

The drip container (III) of FIGS. 7 to 8 is a blow bottle (60) made of a synthetic resin such as polypropylene or polyethylene with a drip port (61) attached, and the drip port (61) has a thin liquid outlet port. Is perforated. (62) is a cap. When using, the cap (62) is removed, and the body of the blow bottle (60) is pressed with a finger to drop the liquid.

[Problems to be Solved by the Invention] The conventional drip containers (I) and (II) are both troublesome because the liquid must be taken out with a dropper or a pipette. There is also a problem that it is difficult to take out when the remaining amount is small.

In the conventional drip container (III), the drip amount must be adjusted by the pushing force of the finger, but since the blow bottle (60) is soft in its entirety, the drip amount greatly differs depending on the pushing force.
Therefore, it is difficult to control the dropping amount. In particular, it is extremely difficult to drop a small amount.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a drip container in which it is easy to take out and drip the liquid and the amount of the drip can be easily adjusted.

[Means for Solving the Problems] The drip container of the present invention comprises: (a) a cylindrical container for containing a drug solution, a rubber stopper for sealing the mouth of the container, and a central portion for sealing the bottom of the container. A liquid medicine container comprising a stopper having an elastic thin portion that is easily deformed when pressed with a finger; (b) a liquid drawing puncture needle that is pierced by a rubber stopper of the liquid medicine container, and a puncture needle. It is characterized in that it is provided with a drip nozzle that is a guide cap that is externally fitted to the mouth of the drug solution container for guiding.

[Operation] In the present invention, the liquid medicine container is filled with the liquid, and the elastic thin portion is pushed with a finger to drop the liquid from the liquid drawing puncture needle.

Since the amount of deformation when pushing the elastic thin part with a finger is small,
The amount of dripping can be controlled almost accurately by adjusting the amount of bottom pressure and the number of times the pressure is applied.

Moreover, since a dropper and a pipette are not required for the dropping operation, the operation is simple and easy.

[Embodiment] Next, an embodiment of the present invention will be described.

FIG. 1 is a partial sectional view of a drug solution container according to an embodiment of the present invention, FIG. 2 is a sectional view of a drip nozzle according to an embodiment of the present invention, and FIG. 3 is a use of the drip container of the present invention. It is a state explanatory view.

In FIG. 1, (1) is a cylindrical container for containing a drug solution, which is made of any material such as metal, glass, or plastic. The mouth portion (2) of the cylindrical container (1) is filled with a rubber stopper (3) to seal the inside.
(4) is an aluminum cap for preventing the rubber stopper (3) from coming off. When using the aluminum cap (4), the top surface portion covering the rubber plug can be torn off by hand and removed. At the bottom portion (upper end portion in FIG. 1) of the cylindrical container, a stopper body (5), which is an elastic thin portion (7) whose center portion is easily deformed, is fixed to seal the inside. The base (6) of the stopper (5) is tightly inserted and fixed inside the cylindrical container (1). The central portion of the plug body (5) is formed, for example, in the shape of a dome that bulges outward. As the material of the plug body (5), natural rubber, synthetic rubber, elastomer, or flexible resin (having elasticity) is used. The central portion (7) of the stopper body (5) is formed thin, has elasticity generated from the material, and is lightly depressed when pressed by a finger. The amount of deformation when pressed with a finger can be changed by changing the thickness and shape of the thin portion (7).

FIG. 2 shows a state in which the drip nozzle (10) is attached to the mouth portion (2) of the cylindrical container (1).
(11) is a puncture needle for liquid discharge, one end of which is sharply formed. Reference numeral (12) is a guide cap having an inner diameter to be fitted onto the mouth portion (2), and the puncture needle (11) is fixed to the center portion thereof. (13) is a cap for protecting the liquid drawing puncture needle (11).

FIG. 3 shows the use state of the drip container of the present invention. An appropriate drug solution is stored in the drug solution container (A), the cylindrical container (1) is gripped by a hand, and the elastic thin portion (7) of the stopper body (5) is pressed by the thumb. Each time the elastic thin portion (7) is pressed, the volume inside the drug solution container (A) decreases, so the drug solution inside is pushed out and the drug solution drops from the puncture needle (11).

 The infusion container of this example has the following advantages.

There is no need to use a pipette or a dropper, which saves time.

When using one bottle, continuous use is possible.

Since it can be used like an ordinary pipette, no erroneous operation occurs even when it is used for the first time.

[Advantages of the Invention] The present invention does not require any trouble in extracting and dropping the liquid, and it is easy to adjust the dropping amount.
