Abstract

PROBLEM TO BE SOLVED: To prevent a medical accident at the time of injection of a liquid medicine. SOLUTION: The liquid medicine is injected using a tube of which both ends are joining ends having a special structure for specifying the liquid medicine and an individual. If there is an erroneous combination between the liquid medicine to be injected and the human body in which the liquid medicine is injected, joining parts are not fitted at the time of joining to make injection impossible. The liquid medicine is injected using a tube of which both ends are joining ends colored in order to specify the liquid medicine and the individual. The erroneous combination can be immediately discovered from color difference.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical drug solution tube for connecting a medical drug solution container and an injection needle for preventing medical mistakes during blood transfusion and infusion of a drug solution.

[0002]

2. Description of the Related Art In the case of conventional liquid infusion and blood transfusion, there are many cases in which human life is impaired due to medical mistakes such as incorrect liquid infusion or transfusion of different blood types.

[0003] Most of the causes are caused by inadvertently injecting an incompatible drug solution without noticing the wrong combination of the drug solution and the human body when connecting the drug solution container and the injection needle with a tube.

[Problems to be solved by the present invention] The present invention has been made for the purpose of preventing such medical errors.

[0004]

Means for Solving the Problems By injecting a drug solution using a tube whose both ends have a special structure for identifying a drug solution and an individual, the drug solution to be injected and the human body to be injected are mistaken. If there is such a combination, the connection portion does not fit at the time of this connection, so that injection is impossible, so that medical errors do not occur.

[0005] Furthermore, on both ends of the tube, indications for identifying a drug solution and an individual are made, so that an incorrect combination can be easily found, thereby preventing medical errors.

[0006]

Embodiment An embodiment of blood transfusion using the present invention will be described below with reference to the drawings. As shown in FIG. 1, the spout 110 of the blood bag 100 containing the A-type blood has a square pillar male shape specified for the A-type blood. Then, the needle base 320 of the injection needle 300 of the patient B who receives the blood transfusion
Is a star-shaped pillar female shape specified for the patient B.

These are connected by a connecting tube 200, through which type A blood is injected into Mr. B's body. One end of this tube 200 has a square pillar female type specified for type A blood. The other end is in the shape of a male star-shaped pillar specified by Mr. B, and blood of type A and B
It fits only into the unique combinations identified by him.

In other words, since both ends are tubes having a key structure that uniquely specifies a combination of a specific blood type and a specific individual, it is physically impossible to combine them with other combinations, thereby resulting in a wrong combination. Blood transfusions cannot occur and medical errors can be eradicated.

Next, an example will be described in which both ends of the connection tube are colored to identify a drug solution and an individual and prevent blood transfusion in an incorrect combination.

[0010] Blood bag 10 containing type A blood
Numeral 0 denotes a colored spout 130 for identifying type A blood, which is colored red. The needle base of the injection needle 300 of the patient B who receives the blood transfusion is a blue colored needle base 240 for identifying the patient B.

[0011] Both ends of the tube 200 connecting this are colored red and blue, and it is confirmed that the red colored spout 130 of the blood bag and the blue colored needle base 240 of the injection needle 200 are the same color. Connect and perform a blood transfusion.

As described above, prior to performing a blood transfusion, the color of the needle base and the color of the blood bag outlet are checked, and the tube is connected. Can be prevented before it happens.

When injecting such a drug solution of the present invention, an injection needle and a blood bag are prepared based on the patient's medical record in advance, and the injection needle is handed to the patient B in advance, and blood transfusion is performed. It is important for the practitioner to take the procedure of transfusion by connecting both with a tube prepared based on the medical record.

That is, the preparation of the blood bag and the injection needle,
By performing a blood transfusion execution and discriminating based on the same chart, and confirming and executing the procedure, a medical error can be reliably prevented, and in this procedure, a wrong combination can be found.

[0015] By the way, there is a limit in specifying all patients and all drug solutions due to differences in colors and differences in structure. For example, it is limited to the day and further limited to wards and medical conditions. It is necessary to be able to identify the individual who performs blood transfusion by means such as computer management.

[0016]

As described above, it is possible to prevent a medical error at the time of injecting a drug solution, and to prevent a loss of valuable human life.
