[0008] 3) The method for preventing atypical blood transfusion according to 1) or 2), wherein the key number is attached to a band-shaped ring fitted to a wrist or an ankle of a patient.

[0009]

Embodiments of the present invention will be described. The present invention is not limited to the embodiments.
The present invention provides a key number to the body of a patient in need of blood transfusion, and locks the blood bag with a lock set with a punch card having the key number. A method for preventing atypical blood transfusion, comprising opening a tablet and enabling blood transfusion from the blood bag to a patient.

[0010] First, a key number is assigned to the body of a patient who needs a blood transfusion, and management is performed using the key number until the blood transfusion is completed. The key number may be set by a number or a symbol, and may be set by combining the number and the symbol. In addition, the key number may be the number of the patient's chart or a number associated therewith. The key number is fixed to the patient's body. The fixing method is not particularly limited, and examples thereof include a method of fixing using a band-shaped ring such as an ankle band (ankle band) and a wrist band.

Next, the punch card corresponding to the key number is mounted on a lock to set a keyhole, and the lock is attached to the blood bag and locked. Locking does not stop the blood outlet of the blood bag by pressing it mechanically, and the blood outlet of the blood bag can be left as it is,
The lock cannot be removed from the blood bag unless it is broken, and the lock can be removed from the blood bag when opened. After attaching the tablet to the blood bag, the punch card is not visible from the outside of the tablet and the key number cannot be read.

When the blood bag locked with the key is released, the medical staff reads the key number attached to the patient's body and operates the lock using the key number, for example. If the key number for operating the lock matches the keyhole set in advance with the key number, the key can be unlocked. The tablet used in the present invention is preferably one that can be removed from the blood bag after opening. By removing the tablet from the blood bag, it is possible to easily confirm that there is no mistake between the patient and the blood.

If the key is not unlocked by the above operation, the keyhole set in advance by the key number does not match the key number operated by the medical staff to operate the lock, and the lock is attached to the blood bag. Healthcare professionals cannot transfuse the patient.

On the other hand, if the lock does not open mechanically due to a mechanical failure of the lock for some reason, or if the punch card is set incorrectly, or if urgent transfusion is required for the patient, medical treatment is required. If the worker can confirm that there is no mistake between the blood and the patient, the blood can be transfused even with the tablet attached to the blood bag. In addition, since the blood bag remains locked, the blood bag can be checked during and / or after blood transfusion, and it is assured that there is no mistake between the blood and the patient.

By the above-described series of operations, mistakes caused by a wrong patient or blood can be eliminated.

A preferred punch card used in the present invention is a punch card in which one character of the key number is displayed on / off at the position of one punch hole. This is because such an arrangement enhances the cognitive ability of the medical staff, and can eliminate mistakes caused by a wrong patient or blood.

As a preferred lock of the present invention, a lower plate in which two rows of holes are formed in a direction perpendicular to the longitudinal direction, which coincides with the holes of the insertion pin and the punch card, and an upper plate in which similar holes are formed, are provided. A card storage unit formed with a space for storing punched cards between the upper plate and the lower plate, an insertion pin mounted perpendicular to the card storage unit, and an insertion pin below the insertion pin on the bottom plate. A lever operating portion of an insertion pin having a lever for moving in a direction perpendicular to the longitudinal direction. When the key numbers match, the insertion pin is inserted into the card storage portion, and the card storage portion is lowered (bottom plate side). A lock that can be opened by being pushed down can be used. With a lock having such a structure, the key number can be reliably recognized with a simple and inexpensive device, thereby eliminating mistakes caused by a wrong patient or blood, and being able to be introduced at a hospital. is there.

The present invention relates to a method for preventing atypical blood transfusion. As a method for preventing a drug from being mistakenly provided, if a tablet is attached using an outer bag, it can be used for other drugs.

Preferred embodiments of the present invention will be described in detail. The present invention is not limited to the embodiments. Create an adhesive key number label and key number punch card with a predetermined key number for each patient who needs blood transfusion. These are preferably created in advance as a single key number sheet as shown in FIG. The punch card shown in FIG. 1 displays one character of the key number at the position of the punch hole, and two spaces are provided for each number, and 1, 2, 3,. Numbers are applied. Hole positions are provided in the upper and lower rows of the key number punch card, and the whole is in two rows and ten columns. The key numbers are 1, 2, 3, ... 9,
0 is set to “on” and any of 0 is set to “off”, and as shown in FIG. 1, 1, 3, 4, 6, 8, 0
Is turned on, 2, 5, 7,
To set “9” to “off”, a punch card having a hole in the lower row may be created.

If the patient needs blood transfusion, the medical worker sets a key number, writes a prescribed matter on the blood dispensing slip and issues a ticket, and the key number on the key number sheet is the same as the number of the dispensing slip. After confirming that they match, a key number sheet is attached and spelled together with the slip. Subsequently, the key number label is affixed to the patient's chart, blood dispensing slip and patient's body (wristband), and the key number sheet is sent to the blood management department together with the blood dispensing slip.

The blood management department prepares a blood bag containing blood of a specific blood type based on the slip. A sample is collected from the blood and tested for blood type, confirming that the blood in the blood bag is of a predetermined type, and attaching a key number label to the test sheet. Subsequently, the key number punch card is taken out from the key number sheet spelled out on the slip, inserted into a key lock described later, fixed to the blood bag, and locked. This blood bag is delivered to the patient.

The medical worker reads the number on the label attached to the patient's wristband and sets the number on the lock locked on the blood bag. When the key number of the punch card previously set as the lock and the set number match, the locked lock is opened and the lock is removed from the blood bag. The health care provider transfuses the patient, returns the used tablet, and ends the transfusion work.

In the above series of operations, if the lock does not open, for example, if the numbers do not match and the lock does not open, there is a high possibility that the blood or the patient will be mistaken.
Healthcare professionals stop transfusion work.

On the other hand, in an emergency such as when the lock is mechanically broken for some reason or when the patient needs immediate blood transfusion,
Without using a key number, the healthcare professional can confirm that there is no mistake in blood type or patient from the patient, the label on the blood bag, the copy of the blood dispensing slip, etc. Can be opened with a cutter or the like to allow transfusion. In this case, it should be noted that since the tablet is still attached to the blood bag, there is no mistake between the blood and the patient during and / or after blood transfusion. Health care workers report to the blood management department that the blood bag was not unlocked after the transfusion, but that there was no mistake between the blood and the patient.
