Description

SAFETY DEVICE OF BLOOD-BAG AND METHOD FOR RELEASING THE LOCK FOR SAFETY}

Blood transfusions are designed to replenish circulating blood volume, increase the oxygen-carrying capacity of blood, and to replenish blood coagulation factors.

Blood transfusions usually involve cross-reaction testing of blood to be transfused at the blood bank when a doctor's prescription is given to the patient.

The cross-reaction test is a test for preventing side effects of blood transfusion caused by an unexpected antibody and reconfirming the patient and the donated blood. If there is no abnormality in the test result, the blood is discharged from the blood bank. The blood information and the patient are then visually confirmed, and if appropriate, a transfusion process is performed. The most careful attention is needed during this transfusion process, especially in the patient identification phase, which is the last step in which blood is administered to the patient.

Neglect of attention can change the blood to be given to another patient, resulting in a life-threatening medical accident. The main cause of such medical accidents is that some of the treatment devices and treatments within the hospital are automated to prevent unnecessary medical accidents, while the final stage of blood transfusion is the identification of the patient's visual information in the blood bag. It is entirely dependent on how the patient is identified.

In the past, there was an inconvenience of having to check the information described in the blood bag and the personal information of the patient directly.

In addition, there is a problem that the blood to be administered is changed because the confirmation of the blood encyclopedia is entirely made by the naked eye of the medical staff.

The present invention relates to a blood bag safety device and a method of releasing the same, and more particularly, to a blood bag safety device and a method of releasing the blood bag when the information on the patient side and the information of the blood bag safety device correspond.

<First Embodiment>

1 is a view schematically showing the configuration of a barcode reader according to an embodiment of the present invention.

Referring to FIG. 1, a barcode reader includes a CCD sensor (Charge Coupled Devide) 100, a digital converter 110, a clock generator 120, a memory 130, a content comparator 140, a signal inverter 150, The electromagnet driver 160 and the speaker driver 170 are included. The CCD sensor 100 receives barcode data, converts the received data signal into an electrical signal, and transmits the signal to the digital converter 110. .

The digital converter 110 converts the patient-side barcode information transmitted from the CCD sensor 100 into a digital signal and transmits it to the memory 130, and converts the barcode information of the blood bag safety device transmitted from the CCD sensor 100 into a digital signal. The clock generator 120 serves to monitor the operation of the barcode reader at predetermined time intervals when barcode data is received.

The memory 130 stores the patient-side barcode information that is converted into a digital signal by the digital converter 110 and transmitted.

The content comparator 140 determines whether the barcode information of the patient-side barcode information stored in the memory 130 and the barcode information of the blood bag safety device detected and received from the CCD sensor 100 correspond to each other.

The patient-side barcode information includes patient information such as ID, name, sex, age, and disease name given to the patient, and blood information such as blood type, red blood cell, white blood cell, platelet, plasma, and the like. It includes patient information such as given ID, name, sex, age, disease name, and blood information such as blood type, red blood cell, white blood cell, platelet, plasma. Therefore, the content comparator 140 extracts at least one piece of information, such as ID, name, and blood type, assigned to the patient from the patient side barcode information including the above information and the barcode information of the blood bag safety device, and extracts the extracted information. Determines whether is equivalent. The signal inverter 150 serves to operate the electromagnet driver 160 when the patient side barcode information and the blood bag safety device barcode information correspond.

The electromagnet driver 160 transmits a magnetic field formation signal to the electromagnet rod when the patient side barcode information and the barcode information of the blood bag safety device correspond.

The magnetic field is formed in the coil of the electromagnet rod by the transmitted signal to release the lock of the blood bag safety device.

The speaker driver 170 generates an alarm sound when the barcode on the patient side and the barcode information of the blood bag safety device do not correspond.

The operation of the bar code reader according to the present invention having such a configuration will be described.

When the barcode information attached to the patient side is received, the received information is converted into an electrical signal by the CCD sensor 100. The converted signal is converted into a digital signal by the digital converter 110 and stored in the memory 130. Then, it receives the barcode information attached to the blood bag safety device.

The received information is converted into an electrical signal by the CCD sensor 100, and then converted into a digital signal through the digital converter 110 is transmitted to the content comparator 140.

The content comparator 140 determines whether the barcode information converted into the digital signal and the barcode information of the patient side stored in the memory 130 correspond to each other. The barcode information for determining whether or not the correspondence may be determined by extracting at least one piece of information such as ID, name, blood type, etc. from the barcode information of the patient and the blood bag safety device, and determining whether or not the corresponding barcode information is extracted. It may be determined whether or not correspondence.

If the barcode information of the patient side and the barcode information of the blood bag safety device correspond to the determination result, the electromagnet driver 160 is operated through the signal inverter 150.

The operation of the electromagnet driver 160 causes a magnetic field to be formed in the coil of the electromagnet rod, which releases the lock of the blood bag safety device.

In addition, while the magnetic field is formed in the coil of the electromagnet rod, the barcode information of the patient side stored in the memory 130 may be erased.

2 is a flowchart illustrating a process of confirming a blood bag safety device for transfusion according to the first embodiment of the present invention.

Referring to FIG. 2, when a doctor's prescription is given to a patient to be transfused, the blood bank executes a cross-reaction test for blood to be transfused. If there are no abnormal reactions as a result of the test, information about the patient to be transfused and blood to be transcribed is recorded in a barcode (S200). The barcode includes, for example, patient information such as ID, name, age, sex, and name of a patient to be transfused and blood information about blood to be transfused, such as blood type, red blood cell, white blood cell, platelet, and plasma. Then attach a blood bag safety device with a barcode containing the patient information and blood information (S210).

Afterwards, if there is a transfusion instruction from the doctor from the doctor, first, barcode information attached to the patient side is received with a barcode reader (S220). The received barcode information is converted into a digital signal and stored in the memory 130.

Then, the bar code reader receives the barcode information of the blood bag safety device (S230), and determines whether it corresponds to the barcode information of the received blood bag safety device and the barcode information of the patient side stored in the memory 130 ( S240).

The barcode information for determining whether the correspondence is extracted from at least one information such as ID, name, blood type, etc. among the barcode information of the patient side and the blood bag safety device, and it may be determined whether or not the correspondence, and the entire barcode information is extracted. It may be determined whether or not correspondence.

As a result of the determination, if the barcode information of the patient side barcode information and the barcode information of the blood bag safety device correspond (S250), the lock in the blood bag safety device is released to open the blood bag safety device (S260). In other words, when the barcode information of the patient and the barcode information of the blood bag safety device correspond to each other, a magnetic field is formed on the electromagnet rod of the barcode reader, and the locking device that is raised upward is pulled down by the magnetic field to open the blood bag safety device.

In addition, while the magnetic field is formed on the electromagnet rod, the barcode information of the patient side stored in the memory may be erased.

On the other hand, if the barcode information of the patient side and the barcode information of the blood bag safety device does not correspond, the alarm driver is generated while the speaker driver 170 of the barcode reader is operated, the locking device is not released (S270).

If a re-search request signal for blood to be transfused is received (S280), the process is executed again from step 230.

For example, consider the case where IDs correspond.

When a doctor prescribes a patient to be transfused, the blood bank runs a cross-reaction test for the blood to be transfused.

If there is no abnormal reaction, the patient's ID, name, age, sex, and name of the patient to be transfused and blood information about blood to be transfused such as blood type, red blood cell, white blood cell, platelet, and plasma are recorded on the barcode. Attach to the safety device. In the future, when the doctor instructs the patient to receive a blood transfusion, first, the patient's information such as ID, name, age, sex, name of the patient and blood information of the patient's blood such as blood type, red blood cell, white blood cell, platelet, plasma, etc. Receive patient-side barcode information comprising a.

The received barcode information is converted into a digital signal and stored in the memory 130. Then, barcode information of the blood bag safety device is received by the barcode reader, and ID information is extracted from the barcode information of the received blood bag safety device and barcode information of the patient side stored in the memory 130. Then, it is determined whether the ID information of the extracted blood bag safety device and the patient ID information correspond.

As a result of the determination, if the patient side ID information and the ID information of the blood bag safety device correspond, the locking device of the blood bag safety device is released and the blood bag safety device is opened.

For example, when a patient requiring red blood cells requires a blood transfusion, the patient first receives and stores barcode information of the patient, and then receives barcode information of the blood bag safety device. Then, the blood type and the red blood cell information are extracted from the barcode information of the patient side and the barcode information of the blood bag safety device to determine whether or not it corresponds.

If the determination is appropriate, the blood bag safety device is opened.

As described above, component transfusion, which is separated and transfused into various blood component preparations such as red blood cells, platelets, and fresh frozen plasma, extracts information such as blood type and platelet or blood type and plasma from the barcode information of the patient and the barcode information of the blood bag safety device.

Then, it is determined whether the extracted patient side information and the information of the blood bag safety device correspond, and if so, to open the blood bag safety device. In addition, the blood bag safety device may be opened if it is determined whether the barcode information of the blood bag safety device and the entire patient side barcode information correspond to each other. For example, barcode information of a blood bag safety device including patient information such as ID, name, age, sex, and disease name of a patient to be transfused and blood information about blood to be transfused such as blood type, red blood cell, white blood cell, platelet, plasma, etc. And patient side barcode information including patient information such as patient ID, name, age, sex, disease name, and blood information of the blood of the patient such as blood type, red blood cell, white blood cell, platelet, plasma, and the like. If the whole correspond, the blood bag safety device is opened.

In another preferred embodiment of the present invention, a cross-reaction test for blood to be transfused in a blood bank is performed in accordance with a doctor's transfusion instruction, and if there is no abnormal response, the information about the patient to be transfused and the blood to be transfused is displayed on a barcode. After recording and attaching to the blood bag safety device, it is determined whether the barcode information of the patient side and the barcode information attached to the blood bag safety device correspond to each other, and if so, the blood bag safety device is opened. Here, the bar code information attached to the blood bag safety device is not only the patient information, such as ID, name, age, sex, name of the patient to be transfused, and blood information about blood to be transfused such as blood type, red blood cell, white blood cell, platelet, plasma, etc. It may include a scheduled transfusion date that the blood transfusion is to be performed on the doctor's prescription for several months.

9 is a flowchart illustrating a process of confirming a blood bag safety device for transfusion according to a second embodiment of the present invention.

Referring to FIG. 9, when a doctor's prescription is given to a patient to be transfused, the blood bank executes a cross-reaction test for blood to be transfused.

If there is no abnormal response as a result of the test, information about the patient to be transfused and blood to be transcribed is recorded in a barcode (S900). The barcode includes, for example, patient information such as ID, name, age, sex, and name of a patient to be transfused and blood information about blood to be transfused, such as blood type, red blood cell, white blood cell, platelet, and plasma. Then attach a blood bag safety device with a barcode containing the patient information and blood information (S910).

Subsequently, if the patient has a blood transfusion instruction from the doctor, first receives the barcode information attached to the patient side with a barcode reader (S920).

The received barcode information is converted into a digital signal and stored in the memory 830. Then, the barcode reader receives the barcode information of the blood bag safety device (S930). The received barcode information of the blood bag safety device is converted into a digital signal to determine whether it corresponds to the barcode information of the patient side stored in the memory (830) (S940).
