Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a mark for distinguishing identification numbers stamped on blood guide tubes connected to blood bags.

(B) Prior Art The blood collection tube and connecting tube connected to the blood bag are stamped with identification numbers 11 at multiple locations along the length of the tube, as shown in FIG.

This is used for verification purposes when testing blood samples. That is, blood collection bag 12
After blood collection, or when transferring the plasma component of the supernatant centrifuged in the blood collection bag 12 to the plasma separation bag 13, the blood collection bag 12 and the plasma separation bag 13 of the blood collection tube 14 or the connecting tube 15,
Cut the test piece leaving the part with the closest identification number 11a (the blood containing blood cells inside is
(containing plasma components) is further divided and used depending on the number of blood type tests, biochemical tests, etc.

By comparing the results of these various tests with the identification number of the test piece and the identification number left on the blood bag side, the test results of the blood components in the blood bag can be displayed on the label of the blood bag. , which are organized in the inspection list.

(c) Problems to be solved by the invention In this way, each identification number is stamped at regular intervals, so when sealing the tube, these identification numbers are stamped so that each identification number can be distinguished. The middle of the space portion 16 was sealed. Identification numbers are generally stamped in white characters,
When pale yellow plasma, which contains almost no red blood cells among blood components, is in the tube, the color tone is similar, so it is difficult to see where the identification number is stamped, and it takes time to check. Not only did it take a while, but in the worst case scenario, the identification number itself could be mistakenly sealed.

If the identification number itself is sealed in this way, not only will it be impossible to confirm the number, but it will also be impossible to compare the identification number on the test piece with the identification number left on the blood bag, making it difficult to perform a blood test. This will cause confusion in the execution of business.

Furthermore, even if blood components containing red blood cells (red), whose identification number is relatively easy to confirm, are in the tube, the sealing process is a continuous process and is carried out in a short period of time. It is difficult to quickly check the spaces between each identification number and perform the sealing work reliably in a short period of time, which increases worker fatigue, and as a result, the identification numbers may be incorrectly inserted. The risk of sealing cannot be avoided.

(d) Means for Solving the Problems The configuration of the present invention will be explained with reference to FIGS. 1 and 2. In FIG. In the guide tube, in the length direction of the blood guide tube 1,
A mark 4 is formed between the identification numbers 2 and 3 along the circumferential direction of the tube.

This mark 4 is stamped (printed) at the same time as the identification number, and depending on the blood components in the tube,
Colored materials such as blue, green, black, and white are used as appropriate. For example, as shown in FIG. 2, a white mark 6 is formed on the blood collection tube 5 that collects blood containing blood cell components, and a white mark 6 is formed on the connecting tube 7 that transfers plasma components.
It is preferable to form the mark 8 in a dark color such as blue, green, or black.

(E) Effect By forming these marks 6 and 8, when blood containing blood cell components is in the blood collection tube 5, the white mark 6 stands out from the red color of the blood collection tube 5, making it easy to identify. Furthermore, when the supernatant plasma component centrifuged in the blood collection bag 9 is transferred to the plasma separation bag 10, the dark-colored marks 8, such as blue, green, and black, indicate pale yellow plasma in the connecting tube 7. It stands out and is easy to identify.

(f) Effect of the invention According to the invention as described above, whether the blood tube contains red blood components such as red blood cells or pale yellow blood components such as plasma, Even if the tube is sealed, the identification numbers can be clearly distinguished from each other, improving work efficiency for blood tests, etc., and there is no need to worry about damaging the identification number when sealing the tube, which can prevent serious accidents during blood transfusions. Effects such as eliminating danger can be obtained.

[Brief explanation of the drawing]

1 and 2 are schematic diagrams showing an embodiment of the present invention. FIG. 3 is a schematic diagram of a blood bag with an identification number stamped on the blood tube. In the figure, 1 is a blood guide tube, 2 and 3 are identification numbers, 4 is a mark, 5 is a blood collection tube, 6 is a white mark, 7 is a connecting tube, 8 is a dark mark,
9 indicates a blood collection bag, and 10 indicates a plasma separation bag.
