Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a medical container having a side slit on the side edge of the container body and a string-like strip on the side edge.

[Prior Art] In general, medical containers such as blood bags are used to attach a pilot tube for cross-testing (which can also be used as a blood collection tube) or a blood collection tube to the corresponding blood bag after blood collection. During centrifugation of blood bags to produce the drug product,
In order to keep the blood collection tubes together, a side slit is provided on the side edge of the container body to form a string-like strip, and blood collection tubes, pilot tubes, etc. are attached by winding them around the strip.

[Problems to be solved by the invention] In this way, while using the blood bag,
Although this strip is useful, it is formed into a string that runs along the side edge of the blood bag.
It has high deformability, and the middle part may be far away from the container body. Therefore, when manufacturing blood bags, the string-like strips become entangled with the manufacturing equipment, causing a problem in that the manufacturing operation is interrupted.

This invention has been made in view of the above-mentioned problems, and an object of the invention is to provide a medical container in which the elongated pieces formed on the side edges of the container body do not have any adverse effect on manufacturing operations. That's true.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the purpose, the medical container according to the present invention has a string formed on the side edge of the container body and integrated with the container body. A medical container having a slit defining an elongated piece having a shape, the elongated piece integrally having a connecting portion breakably connected to the container body at approximately the center of the elongated piece. It is characterized by

Further, according to the first embodiment of the medical container according to the present invention, the connecting portion of the elongated small piece has a breaking strength set to a value in the range of 0.5 (Kg) to 1.5 (Kg). It is a feature.

Furthermore, according to a second embodiment of the medical container according to the present invention, the container main body and the elongated piece are integrally formed from vinyl chloride resin, and the connecting portion of the elongated piece has an attachment length of 1 ( It is characterized by being set to a value in the range of 3 (mm) to 3 (mm).

[Function] Since the medical container according to the present invention is constructed as described above, the string-like elongated piece provided on the side edge of the container main body is connected to the container main body through the connecting portion at approximately the center. connected. Therefore, during the manufacturing process of the medical container, the elongated piece will not separate from the side edge of the container body, and will therefore not become entangled with the manufacturing equipment. In addition, when it is necessary to attach a blood collection tube, etc. to a medical container during use, by breaking this connection and opening the long and thin piece over the entire length, the blood collection tube, etc. can be attached to the container as a long and thin piece. You will be able to wrap it around.

[Example] Hereinafter, an example of the medical container according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a blood bag 10 as an embodiment of the medical container according to the present invention is integrally formed from a substantially transparent soft vinyl chloride resin. The blood bag 10 includes a vertically long, substantially rectangular container body 12 having a flat hollow portion inside. A proximal end portion of a blood sampling tube 16 having a blood sampling needle 14 attached to its distal end is connected to the upper portion of the container body 12 . In addition, this container body 1
A pair of extraction ports 18a and 18b are attached to the upper part of the blood collection tube 16 in parallel with the blood collection tube 16.

Both side edges of the container body 12 extend substantially linearly, and a pair of side slits 20a are provided in the middle of each side edge, proximate to each side edge and extending along the side edge. 20b is formed. Both side slits 20a and 20b are linearly aligned with each other and set to have the same length.

That is, string-like side slit pieces 22 are formed at each side edge of the container body 12 due to the side slits 20a and 20b. Each side slit piece 22 is firmly fixed and connected to the container body 12 at both upper and lower ends in the figure. Here, the elongated piece 22 is connected to the container body 12 at the center via the portion between the side slits 20a and 20b. Both side slits 20a, 20
The part between b is the connecting part 24 of the side slit 22.
It is functioning as.

This connecting portion 24 is set to be breakable by the operator's hand. That is, by breaking this connecting portion 24, both side slits 20a, 20
b are connected to each other to form one side slit.

Here, the breaking strength of this connecting portion 24 is 0.5
(Kg) to 1.1 (Kg). Since the breaking strength of the connecting portion 24 is set within this range, the connecting portion 24 will not be broken under normal conditions, but will be easily broken by the operator's hands.

Note that the above-mentioned range of breaking strength is just a preferred example, and practically it may be set within the range of 0.3 (Kg) to 4.0 (Kg). That is, the breaking strength is
If the weight is less than 0.3 (Kg), the connecting portion 24 will easily break, and for example, the small strip 2
If any member gets caught on the 4, it will break, making it impractical.

On the other hand, if the breaking strength is greater than 4.0 (Kg), excessive force is required to break the connecting portion 24, and in some cases, a breaking tool such as scissors is required, resulting in poor operability. Become. Furthermore, there is a risk that the elongated piece 22 itself may be cut off before the connecting portion 24 is broken, which is still impractical.

In this way, by setting the breaking strength of the connecting portion 24 within the above-mentioned range, the connecting portion 24 will not break under normal conditions, and the operator will not be able to tear it apart manually with the intention of breaking it. When this occurs, the connecting portion 24 will be surely broken.

In addition, since this connecting portion 24 has the above-mentioned breaking strength, the connecting length (L) of this connecting portion 24 is as follows.
When the above-mentioned vinyl chloride resin is used as the material, the thickness is set within the range of 1 (mm) to 3 (mm).

The operation of the blood bag 10 constructed as described above will be explained below.

In the manufacturing process of the blood bag 10, the blood bag 10 is transported, for example, in order to attach the blood collection tube 16 to the container body 12 and to attach a label (not shown) to the surface of the container body 12. . During such transportation, the elongated pieces 22 formed on both side edges of the container body 12 are connected to the container body 12 via the connecting portion 24 at the center thereof. For this reason, the center portion of the string-like elongated piece 22 is far away from the container body 12, and there is no possibility that it will get caught in the manufacturing equipment during transportation. In this way, the blood bag 10 of this embodiment is transported without any stoppage of the manufacturing operation, thereby improving manufacturing efficiency.

On the other hand, when blood is collected using this blood bag 10 or when blood that has already been collected is centrifuged, the operator manually breaks the connecting portion 24 and inserts each elongated piece 22 into a container only at both the upper and lower ends. It is attached to the main body 12. In this state, as shown in FIG. 2, the blood collection needle 14 is wound around the elongated piece 22, so that the blood collection tube 16 is entangled with the elongated piece 22.

In this way, during blood collection, the pilot tube using the blood collection tube 16 and the blood bag 10 are reliably matched. Further, during centrifugation, the blood collection tube 16 is securely attached to the blood bag 10, so that even under high speed rotation, the blood collection tube 16 does not pop out, ensuring safety.

As detailed above, according to this embodiment,
During manufacturing, since the small elongated piece 22 is connected to the container body 12 at the center via the connecting part 24, there is no possibility that the elongated small piece 22 may get caught in the equipment and have an adverse effect such as stopping the manufacturing operation. will be reliably prevented. Further, since the connecting portion 24 can be broken by the operator's hand, the connecting portion 24 can be broken by hand as necessary, improving operability.

It goes without saying that this invention is not limited to the configuration of the above-described embodiment, and can be modified in various ways without departing from the gist of the invention.

[Effects of the Invention] As detailed above, the medical container according to the present invention includes a slit formed on the side edge of the container body and defining a string-like elongated piece integral with the container body. The medical container is characterized in that the elongated piece has a connecting portion that is breakably connected to the container body and is integrally formed in a substantially central portion of the elongated piece.

Therefore, according to the present invention, a medical container is provided in which the elongated pieces formed on the side edges of the container body do not have any adverse effect on manufacturing operations.
