DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing blood type mis-recognition at the time of blood transfusion for preventing blood type mistakes at the time of transfusion.

[0002]

2. Description of the Related Art Conventionally, blood transfusion is performed in a state as shown in FIG. Blood to be transfused is a transparent blood pack 1
And is held by a stand 2. A patient 4 lying on a bed 3 is located below the blood pack 1, and blood is supplied from the bottom of the blood pack 1 to the body of the patient 4 by a tube 5.

[0003] A patient 4 requiring a large amount of blood transfusion is generally in a severe condition, and is often unconscious due to anesthesia or the like. Since it is not preferable to inject a large amount of blood into the patient 4 in a short time, the blood transfusion takes a relatively long time.

[0004]

In transfusion as shown in FIG. 4, it is important that the blood type supplied from the blood pack 1 to the patient 4 matches the original blood type of the patient 4. . If you make the wrong blood type, depending on the combination of blood types,
It can be fatal to patient 4. For this reason, it is necessary to handle blood transfusions carefully so as not to make a mistake in blood type.

Although the blood pack 1 as shown in FIG. 4 is basically transparent so that the contents can be seen clearly, the blood type cannot be distinguished from the appearance. Blood type etc.
For example, they are indicated by letters, but at a short distance they are difficult to identify. In addition, even if the blood type of the patient 4 can be determined by referring to, for example, a medical chart, it is not preferable from the viewpoint of privacy protection that a person other than the doctor in charge can freely view the blood type. For this reason, it is difficult to say that the blood types in the blood transfusion as shown in FIG. 4 are always performed reliably in the blood types of the blood pack 1 and the blood types required by the patient 4. If the patient 4 has sufficient knowledge and consciousness, it may be possible to prevent blood type mistakes to some extent, but as described above, the contents of the blood pack 1 are difficult for the patient 4 to understand, and moreover, the patient's 4 Since there is often no awareness, there is very little possibility that the patient 4 itself can prevent mistakes in blood type. For this reason, when performing a plurality of blood transfusions at the same time in a large hospital or the like, blood type mistakes are particularly likely to occur.

[0006] It is an object of the present invention to provide a method for patient
An object of the present invention is to provide a method for preventing blood type misrecognition at the time of blood transfusion, which can surely prevent blood type mistakes.

SUMMARY OF THE INVENTION The present invention provides, for each blood group,
The identification color is determined in advance, the identification color corresponding to the blood type of the blood to be transfused is displayed on the blood pack used at the time of transfusion, and the blood type to be transfused is displayed on the body of the patient to be transfused. Indicate the color for identification and, for the identification color corresponding to the blood type of the blood to be transfused, perform blood transfusion only when the indication on the blood pack matches the indication on the patient to prevent blood type misidentification. This is a method for preventing blood type misidentification during blood transfusion.

According to the present invention, an identification color is determined in advance for each blood type. For example, type A is yellow, type B is blue, and blood type is made to correspond to a specific color. The blood pack used at the time of blood transfusion displays a color for identification corresponding to the blood type of the blood to be transfused. The color of the blood type to be transfused is displayed on the body of the patient to be transfused by using an object worn on the body such as a bracelet. If the correspondence between blood type and color is standardized, the correspondence between the displayed color and the patient's own blood type should be checked while the patient is conscious, and if there is an error, correct it. it can.
When performing a blood transfusion, it is possible to easily confirm whether or not the display of the blood pack and the display of the patient match with respect to the identification color corresponding to the blood type of the blood to be transfused. Only perform blood transfusions if you have. As long as the identification color displayed on the blood pack matches the blood type of the blood in the blood pack, blood transfusion can be performed without error.

[0009]

FIG. 1 shows a state in which a blood transfusion is being performed according to an embodiment of the present invention. Blood for transfusion is stored in blood pack 21. Blood pack 21 is suspended from stand 22 and held. The stand 22
The patient 2 is arranged on the side of the bed 23 and the patient 2
4 is asleep. Blood to be transfused into the patient 24 flows into the patient 24 from the bottom of the blood pack 21 through the tube 25. A needle for introducing blood into a blood vessel such as a vein is provided at the distal end of the tube 25, and the needle tip is inserted into the body of the patient 24. Such a blood transfusion state is basically the same as that in FIG.

The blood pack 21 according to the present embodiment is provided with a blood type display 26 using identification colors corresponding to blood types. The body of the patient 24 is provided with a blood type indicator 27 in a color corresponding to the blood type, for example, on an arm or the like. The blood type indicators 26 and 27 are standardized according to the blood type, and a specific blood type always corresponds to a specific color. For example, the correspondence between major blood types and identification colors, such as yellow for type A, blue for type B, green for type O, and white for type AB, is standardized in advance.

FIG. 2 shows the blood pack 21 of FIG.
This shows a state in which the blood type display 26 is displayed in a blood type identification color. FIG. 2A shows a state in which a general ABO blood type display is performed. A blood type display 26 is provided on the upper part of the blood pack 21, and a transparent part 28 is provided on the lower part of the blood pack 21. Since the lower part of the blood pack 21 is the transparent portion 28, when the amount of blood in the blood pack 21 becomes smaller, the position of the liquid level can be easily confirmed from the outside, and the remaining amount of blood can be reduced. It can be easily grasped. FIG.
(B) shows the ABO blood type display 26 and RH-
This shows a state in which an additional unit 29 is provided. Addition part 29
The display such as RH- can be performed by deciding the corresponding color and performing the display in different colors, or directly by characters such as "RH-". Also in the case of displaying by characters, it can be easily recognized from the outside that it is different from the blood type display 26 simply by color.

In the blood pack 21 of the present embodiment, the transparent part 28 is only the lower part,
When there is enough blood inside, there is no need to check the position of the liquid level from the outside,
As in the case of the conventional totally transparent blood pack 1 shown in FIG. 1, the liquid level of the blood inside can be confirmed.

FIG. 3 shows an example of the blood type display 27 worn by the patient 24 in FIG. In this embodiment, the blood type indicator 27 worn by the patient 24 is formed, for example, on a bracelet 31 worn on the arm 30. Blood type display 27 formed on bracelet 31
, The name 32, the details 33 of the operation, and the like can be described, and information necessary for handling can be displayed together with the patient 24 unconscious. Also for the patient 24, the blood type display 27 is performed in a color associated in advance, and the blood type display 26 of the blood pack 21 matches the blood type display 27 of the patient 24, so that the blood type display Blood transfusions can be made without error. The correspondence between blood type and color is standardized, and patient 2
If the patient 4 is in a state where it can be easily known, the wristband 31 can be worn while the patient 24 is sufficiently conscious, and the contents such as the blood type display 27 and the name 32 can be sufficiently confirmed by himself. . The details of the operation 33 and the like can be entered after the patient 24 loses consciousness due to anesthesia or the like.

In this embodiment, the blood type display 27 is displayed on the arm 30 of the patient 24 as the bracelet 31.
The display may be performed at a place different from the arm 30, such as the ankle of the patient 24. If the blood type display 27 is provided as a bracelet 31 or a leg ring, the blood type display 27 can be kept from being removed even when the patient 24 takes a bath, etc.
The error of the blood type display 27 of 4 itself can be more reliably prevented by always performing the blood type display 27.

[0015]

As described above, according to the present invention, the correspondence between the blood type of the blood stored in the blood pack and the blood type of the patient is determined based on the relationship between the blood type and the color, which are associated in advance. Mismatch can be easily confirmed, and by performing blood transfusion only when the colors match, it is possible to reliably prevent a blood type error.
