問題があった。2. Description of the Related Art An infusion set (commonly called an infusion set) used for injecting a drug solution into a patient's vein includes:
In order to perform a precise infusion, there is a type provided with a cylindrical container such as a graduated measuring cylinder called a metering cylinder. The metering cylinder is provided below the bottle needle of the infusion set,
A predetermined amount of the drug solution in the infusion container is temporarily stored in the metering cylinder, and then the infusion is performed. By using such a metering cylinder with a scale, it is possible to set the infusion volume and accurately check the injection volume. Therefore, this infusion set with a metering tube is used when a medicinal solution for which the dose needs to be strictly controlled is used, or when a pediatric, operating room, or I
It is used when performing accurate infusion for patients who require precise infusion management such as CU. For this reason, it is necessary to frequently check the infusion amount of the infusion solution.
There were the following problems. Since the conventional metering cylinder has only a scale in a transparent plastic container, the liquid level is difficult to understand in the case of a colorless and transparent chemical. Especially hospital walls are often white or cream colored,
When the metering cylinder is viewed from a distance with such a color as a background, it is more difficult to check the liquid level. Therefore, there is a problem that the progress of the infusion cannot be grasped unless the nurse goes to the vicinity of the metering tube and checks it. In addition, there is a possibility that reading of the liquid level may be erroneous even when viewed from near, and there is also a problem in terms of safety.

FIG. 1 is an embodiment showing a metering cylinder of an infusion set having a mirror-finished back surface and its attached members according to the present invention. In FIG. 1, the metering tube 4 has a mirrored portion 5 on its back surface, is connected to the bottle needle 1 by a flexible tube 3, and is connected to a drip tube 6 at a lower portion thereof. The connection between the drip tube 6 and the metering tube 4 can also be performed by a flexible tube. A roller clamp 2 is provided between the bottle needle 1 and the flexible tube 3 in order to control opening and closing of the supply of the infusion solution to the metering tube.
Is provided. The flexible tube is made of, for example, soft vinyl chloride, and the metering tube is made of, for example, transparent polycarbonate, polystyrene, or the like. In this way, an accurate infusion volume can be read. The metering tube 4 may have a co-injection port at the top of the metering tube so that co-injection of another drug is performed.
When the liquid medicine in the metering tube runs out, an automatic stopper function for closing the flow path can be provided.

いう優れた効果を奏するからである。The light reflector, especially the mirrored portion, is preferably provided in a strip shape in the vertical direction over the entire back surface.
It is preferable that the width in the lateral direction is narrower than the entire back surface. The reason is that the width of the colored or light-reflected part appears to be enlarged by the lens effect in the part containing the chemical liquid compared to the part without the chemical liquid, and the part where the width changes is the liquid surface This is because, in conjunction with the fact that it is colored or made into a light reflector, there is an excellent effect that the determination of the liquid level becomes very easy.

きる。[0011] The light reflection on the back surface of the metering cylinder can be performed by various methods. For example, a metal thin film layer that forms a mirror surface layer on the inner wall or the outer wall surface of the back surface of the metering cylinder can be formed using vacuum deposition, metal spraying, chemical plating, or the like. Similarly, the inner wall or outer wall of the metering cylinder can be made to have a specular gloss by using a buff or the like. Further, a metal foil (for example, an aluminum foil or a silver foil), a light reflecting film or a sheet, etc. is fixed to the metering tube by the same means as employed for fixing the coloring tape or the sheet to form a light reflecting portion. be able to. Examples of the light reflecting film or sheet include those obtained by depositing a metal on a base material (eg, plastic, cellophane, paper, cloth, etc.) or those obtained by pressing a metal foil against such a base material (eg, gold paper, silver paper, etc.). Can be In addition, light reflector,
In particular, in the case of a mirror surface, not only does the width of the light-reflecting portion change on the liquid surface, but also the reflection of light rays is remarkably different between the part containing the medicine and the part not containing the medicine,
The effects of the present invention are particularly remarkable. Further, the means of the present invention can be diverted to other medical instruments that need to accurately and easily check the liquid level, in addition to the metering tube of the infusion set.
