DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a storage container for storing blood for transfusion used during surgery, or for storing a drug solution used for extracorporeal circulation treatment or infusion treatment.

In the current liquid storage container, a mark corresponding to the liquid surface at the time of filling the liquid is marked with magic ink (registered trademark) , tape, or the like, and after discharging a predetermined amount of liquid,
The amount of liquid transfer is checked by drawing a scale corresponding to the liquid surface after discharge from the scale marked with the mark.

[0003]

Means for Solving the Invention [1] The present invention has a square shape
Or a slide plate having a groove with a circular cross section,
The needle is integrally formed on the side of the plate and two
Volume indicator needle formed by integrally forming the handle
On rails with square or circular cross section
Provide a freely mounted liquid storage container. [2] The present invention provides:Liquid at the time of liquid filling as the volume indicating needle
Volume indicator hand to indicate body volume and liquid volume at the end of liquid discharge
A capacity indicating needle for indicating the amount is slidably attached to the rail.
A liquid storage container according to [1] is provided.  [3] The present invention has a tube mounting portion at the end of the container body.
[1] to [1]2]
ToA liquid storage container according to any of the preceding claims.

1 is a schematic view of a liquid storage container 1 of the present invention (FIG. 2 is an enlarged view of a cross section taken along line AA of FIG. 1). The liquid storage container 1 includes a container main body 2 made of a transparent hard resin such as polycarbonate, a rail 3 integrally formed in a vertical direction on the surface of the container main body 2, and a capacity slidably mounted on the rail 3. And a pointer 4.

The capacity indicating needle 4 is composed of a slide plate 5 having a groove 5a having a rectangular cross section and a needle 6 integrally formed on a side of the slide plate 5. FIG. 3 shows a preferred embodiment of the present invention .
FIG. 4 is a cross-sectional view showing a specific capacity indicating needle 14 (FIG.
FIG. 3 is a sectional view taken along the line CC in FIG.
4 is a slide plate 15 having a groove 15a having a rectangular cross section.
And needles 16 integrally formed on both sides of the slide plate 15
And two handles 17 integrally formed on the top surface of the slide plate 15.

The rail 3 is formed integrally with the surface of the container body 2 when the container body 2 is formed by injection molding or blow molding. The cross section of the rail 3 is the slide plate 5
Are formed in a rectangular shape corresponding to the grooves 5a and 15a.
The cross section of the rail 3 and the cross sections of the grooves 5a and 15a are triangular, square and modified shapes (so-called angular shapes), circular, elliptical shapes and modified shapes other than the rectangular shape. (A so-called circular shape). In short, any shape can be used as long as the capacity indicating needle 4 can be slidably mounted on the rail 3. The capacity indicating needle 14 formed in a clip shape can be easily slid on the rail 3 by pinching the two handles 17 in the direction of the arrow (inside) to increase the space between the groove 15a and the rail 3. As the capacity indicating needles 4 (14a), two pieces 4a (14a) for indicating the liquid capacity at the time of liquid filling and two pieces 4b (14b) for indicating the liquid capacity at the end of liquid discharge are mounted on the rail 3.

A mouth 8 is attached to an end of the container body 2. The mouth 8 may be fitted with a rubber stopper 8a for puncturing an infusion needle, or a connector-like mouth 9 having a tube mounting portion 10 (tube mounting groove) as shown in FIG. It can also be worn. Thereby, it can be easily connected to another infusion tube to quickly discharge the liquid therein. The shape of the mouth portion 9 may be either a male connector shape or a female connector shape, that is, any shape as long as it can be connected to another infusion tube.

An example of a method of using the liquid storage container 1 will be described. As shown in FIG. 1, first, the capacity indicating needle 4a is set to a graduation position corresponding to the liquid level at the time of liquid filling. Subsequently, a plastic needle is punctured into the mouth portion 8 to discharge a predetermined amount of liquid through the mouth portion 8, and at the end of the liquid discharge, the volume indicating needle 4b is set to the graduation position corresponding to the liquid level, and the volume indicating portion is set. The transfer amount of the liquid can be checked by drawing the indication scale of the capacity indication needle 4b from the indication scale of the needle 4a.

[0009]

The scale of the liquid level at the time of filling the liquid and the scale of the liquid level at the end of the liquid discharge can be surely indicated by the capacity indicating needles (more reliably by using two capacity indicating hands). It is possible to accurately watch the fluctuation of the liquid level, so that the liquid transfer amount can be accurately grasped.
