Description

  The present invention relates to a blood collection tube to which an adapter provided with an identification mark such as an RFID or IC tag (hereinafter simply referred to as “tag”) and a bar code is detachably attached. Tags that automatically acquire and recognize the blood collection information, patient information, test blood collection information, etc. by the label, dispose of the blood collection tube after use, such as blood test completion, and allow the adapter to be reused The present invention relates to a blood collection tube and a blood collection work support system.

Normally, in a medical institution such as a hospital, after a doctor completes a diagnosis for a patient, when the doctor inputs the patient's diagnosis results and test blood collection information to his / her personal computer terminal, the information is automatically stored in the medical system computer ( Registered in the host computer database.
On the other hand, in the blood collection room, a patient's blood collection is accepted, and this is reflected in the blood collection preparation device of the examination system. The blood collection tube preparation apparatus acquires patient information of the patient who has received the reception from the database, and selects and retrieves a blood collection tube of a tube type necessary for the patient's examination for each examination item. And the identification label which printed information, such as patient ID, is affixed to each blood-collecting tube, is accommodated in a tray for every patient, and is sequentially carried out to the blood-collecting operation site of a blood-collecting chamber.

At the blood collection work site, the information about the patient in the tray that has been transported is read with a barcode reader from the identification label affixed to the tray, the blood collection instruction sheet placed in the tray, or the identification label affixed to the blood collection tube, This is displayed on the display device to call the patient. Then, after collating the patient ID stored and stored in the blood collection reception slip possessed by the called patient with the displayed patient ID, blood is collected if identity is obtained. The blood collection tube containing the sample after blood collection is accommodated in a standing state on the test tube rack and transported to the examination room.
In the laboratory, the patient ID displayed on the identification label of the blood collection tube is read with a barcode reader, the examination information of the patient is obtained from the database of the host computer, and the sample that has entered the blood collection tube is dispensed. A predetermined inspection is performed according to the inspection information. The inspection result is transmitted from the laboratory computer to the database of the host computer and registered.

As described above, in the conventional blood collection and inspection process, the barcode of the blood collection tube or the tray is read by the barcode reader in each step of the blood collection process and the inspection process, and the inspection blood collection instruction information from the doctor is based on the patient ID. Collation is made so that medical errors do not occur.
However, in a medical institution where the number of blood collections and tests per day is large, the burden on workers to read patient IDs, blood collection information, etc. using a barcode reader from blood collection tubes, etc. is large and efficient. There was a problem that hindered smooth work.
Therefore, in the past, a technique has been developed in which the reading operation by a barcode reader from a blood collection tube or the like is eliminated, and this can be automated, and the technique described in Patent Document 1 or Patent Document 2 or the like Is known.

  In the technique of Patent Document 1, a memory semiconductor integrated circuit chip (IC tag) is integrally embedded in a container for storing a sample for medical examination or the like. The IC tag can be written to and read from in an electrically non-contact state. At the blood collection site, the patient's name, sex, age, medical subject, sample collection date and time, and necessary test items are written to the IC tag at the time of blood collection in a non-contact manner using an IC tag reader / writer. I write to the tag. Then, the information written from the IC tag is read as required and written to an inspection report or the like.

On the other hand, in the technique of Patent Document 2, a wireless tag (RFID) is attached to an identification label to be affixed to a blood collection tube, and when this identification label with a tag is affixed to a blood collection tube with a blood collection tube preparation device, The patient ID, examination information, etc. are written in the wireless tag. Then, in the inspection process after blood collection, the information of the wireless tag is read in a non-contact manner, collated with the information of the host computer, and the sample is analyzed after the collation is confirmed.

  However, in the technique of Patent Document 1, the same container after the sample is collected is reused, which is problematic from the viewpoint of pathogenic bacteria, viruses, and hygiene. Etc., it is regarded as a single-use medical device. As described above, the technique of Patent Document 1 on the premise that the blood collection tube for accommodating the blood sample is reused is not preferable from various viewpoints. On the other hand, when the reuse is stopped and the entire container used for blood collection is disposed of, there is a disadvantage that the cost is increased by an amount corresponding to the IC tag.

In the technique of Patent Document 2, it is necessary to peel and remove the label with the wireless tag from the blood collection tube after use, and separately collect the blood collection tube, the label, and the wireless tag, and dispose of each. However, in practice, it is difficult to separate the blood collection tube from the label, and a large facility is required for carrying out the operation, which increases the cost. Therefore, the label may be discarded without being peeled off. In such a case, since the patient's personal information is included in the label and the wireless tag, there is a serious problem of causing leakage of personal information.
In addition, after accepting the test, the blood collection tube selects and takes out the tube type of the blood collection tube based on the instruction information of the test blood collection from the doctor to the patient, and prints a barcode such as the patient ID on this It was necessary to prepare blood collection tubes for all tube types by applying the label. Therefore, it is necessary to prepare consumables such as a label and ink in addition to the blood collection tube, and there is a problem that the running cost is high.

  The present invention is an improvement and removal in view of the above-mentioned conventional problems, and an adapter with a tag is detachably attached to a blood collection tube and collected after use of the blood collection tube such as completion of a blood test. By disposing of blood vessels and allowing adapters to be reused, the company intends to provide technology that can effectively use resources and reduce consumables.

  The means of claim 1 employed by the present invention to solve the above problems includes a blood collection tube main body, an adapter that is detachably attached to the blood collection tube main body, and an RFID or an IC tag mounted on the adapter. A non-contact medium or a tag of the contact medium, and a bar code attached to the adapter, and at least the same and unique identification of the non-contact medium or the tag of the contact medium and the bar code This is a tagged blood collection tube characterized in that it is marked with a symbol, the blood collection tube is discarded after use, and the adapter is reused.

  The means of claim 2 adopted by the present invention to solve the above-mentioned problem is that the adapter is made of an elastic material and is attached to and detached from the blood collection tube main body using elasticity, and is a non-contact type medium or a contact type medium.

The tag according to claim 1, wherein a tag of the medium is embedded in the outer cylinder, and the barcode is embedded in the outer cylinder or indirectly described on the outer surface of the outer cylinder via a label. It is a blood collection tube.

  Further, the means of claim 4 adopted by the present invention to solve the above-described problem is that, when a blood collection patient receives blood collection, means for reading test blood collection information necessary for the blood collection patient from a host system or the like; The necessary number of blood collection tubes according to claims 1 to 3 prepared in advance based on the read test blood collection information is arbitrarily taken out, and a unique identification symbol of each blood collection tube is associated with the ID of the blood collection patient. , Means for recording the test blood collection information of the patient on the non-contact type medium or contact type medium tag of each blood collection tube, and recorded on the tag of the non-contact type medium or contact type medium after completion of the test of the collected blood sample It consists of means for erasing the test blood collection information and means for removing the adapter from the blood collection tube from which the test blood collection information has been erased, disposing the blood collection tube, and stocking the adapter for reuse. It is a blood collection business support system according to claim.

In the first aspect of the invention, an adapter in which a tag of a non-contact type medium or a contact type medium such as an RFID or an IC tag and a barcode is attached by means such as embedding and printing is prepared, and this is taken. It is detachably attached to the blood vessel. An identification code unique to the adapter is attached to the RFID or IC tag of the adapter and the barcode by recording or printing. Therefore, in a blood collection tube equipped with an adapter, the unique identification code recorded and stored in the tag of the adapter is read using a wireless non-contact type reader / writer or a contact type IC card reader. Thus, it is possible to identify individual blood collection tubes. In addition, by reading the barcode information of the adapter using a barcode reader, it is possible to identify individual blood collection tubes.
With such a blood collection tube, it is possible to prepare the blood collection tube of the patient just by associating the ID of the blood collection patient with the unique identification code of the adapter, and the tube of the blood collection tube as in the past. It is possible to omit the extremely complicated work of selecting and extracting the species, printing the patient ID, blood collection information, etc. on the label and attaching the label to each individual blood collection tube. In addition, the patient ID and the like are not written in kanji, hiragana, katakana or the like that can be read by a general third party, and there is no possibility that personal information or the like will be stolen by a third party at the time of blood collection or in an inspection process.
Moreover, in the middle of transporting blood collection tubes or in the inspection process, it is possible to automatically read the tag information and display the patient ID, blood collection information, etc. just by carrying the blood collection tube, Automation is possible throughout the blood collection and testing process.
Furthermore, after the inspection is completed, if the adapter is removed from the blood collection tube and the blood collection tube is disposed of, and the adapter is reused, resources can be used effectively and problems such as leakage of personal information may occur. It is not possible, and the security is excellent.

  In the invention of claim 2, the adapter is a cylindrical elastic material used as a grip of, for example, a ballpoint pen or a mechanical pencil.

If the adapter is made of such an elastic material, it will not fall off unnecessarily unless it is removed by applying a forced external force in a normal blood collection tube. Therefore, it is possible to automate the attachment of the elastic material and the removal after use, and a nurse or the like can individually perform the attachment / detachment work as necessary.

  In the invention of claim 3, the adapter is configured as an outer tube having a double tube structure that can be fitted onto the blood collection tube, and is formed of the same material as that of the blood collection tube. Also in this case, as in the case of claim 2, the non-contact type medium or the tag of the contact type medium is embedded in the outer cylinder, and the barcode is embedded in the outer cylinder or outside the outer cylinder. It is written indirectly on the surface via a label.

In the invention of claim 4, blood collection work and inspection work are performed using the blood collection tube according to claims 1 to 3, and the work is simplified in each case. The blood collection tube is discarded and the adapter is reused.
That is, when a blood collection patient receives a blood collection, the host computer is accessed by inputting the patient's ID from the reception terminal, and the test blood collection information necessary for the blood collection patient is obtained. Then, the necessary number of blood collection tubes according to claims 1 to 3 prepared in advance based on the read test blood collection information is arbitrarily extracted, and a unique identification symbol of each blood collection tube is associated with the ID of the blood collection patient Keep it. At the same time, the test blood collection information of the patient is recorded and stored using a reader / writer in the non-contact medium or the contact medium tag of each blood collection tube.

Therefore, at the blood sampling work site and the inspection process, the patient information and the test blood sampling information can be automatically read from the tag of the adapter through the reader / writer by distributing the patient's blood sampling tube. Therefore, it is possible to display and call the patient on the calling device.
Further, after the examination of the collected specimen is completed, the examination blood collection information recorded on the tag of the non-contact type medium or the contact type medium is erased by the reader / writer. After that, the adapter is removed from the blood collection tube, the blood collection tube is discarded, and the adapter is transported to a stocking department for reuse.

  Next, an operation mode of the blood collection work support system when blood collection and examination are performed using the blood collection tube 1 or 6 configured as described above will be described with reference to the block diagram showing the system configuration of FIG. When a blood test is required for a patient who has been examined by a doctor, the contents of the test instruction are registered in the host computer 10 such as a database of a medical computer and an ordering system computer through the doctor's personal computer. The patient goes to the blood collection room and accepts it at the reception unit in front of the entrance. In the reception unit, the card reader 8 reads the patient ID such as the examination ticket and outputs the patient ID from the reception personal computer terminal 9 to the blood collection tube preparation device 11. The blood collection tube preparation device 11 acquires patient information of the receiving patient from the database of the medical computer, picks up the number of blood collection tubes necessary for the examination of the patient, and puts the patient ID in the tag of the taken blood collection tube 1 or 6 Is recorded and stored in a non-contact manner by a wireless reader / writer or the like. As a result, the unique identification symbol of the blood collection tube main body 1 and the patient ID are associated with each other.

  The blood collection tube preparation device 11 sorts out the collected blood collection tubes 1 or 6 according to examination items, and records blood collection information for each examination item of the patient on the tag 4 of each blood collection tube main body 1 with a wireless reader / writer. I try to save it. Examples of blood collection information include biochemistry, blood cells, coagulation, immunity, serum, and blood transfusion. The blood collection tube 1 or 6 prepared in this way is stored in a tray for each patient and carried out to the blood collection work site.

  At the blood collection work site, when the blood collection tube 1 or 6 stored in the tray passes in front of the reader / writer, the patient ID is automatically read and the information is displayed on a call display device in the waiting room. The patient sees this, enters the blood collection room, and goes to the called blood collection table. Each blood collection operator collates tag information of a blood collection tube on the blood collection work table with a patient ID such as an examination ticket or a blood collection card held by the called patient, and performs blood collection if they match.

  The blood collection tube 1 or 6 after blood collection is accommodated in a standing state on the rack, and the inspection process is carried. In the examination step, the patient ID and blood collection information recorded and stored in the tag are read and displayed by the read function of the wireless reader / writer. Further, it is only necessary to access the host computer 10 from the read patient ID, obtain examination information of the patient, and carry out the examination as instructed by the doctor. The inspection result is output to the host computer 10 and recorded therein.

  After completion of the examination, the adapter is removed from the blood collection tube main body 2 by the adapter separation device 14 or manually, and the blood collection tube main body 2 is disposed of. As for the adapter, the patient ID, examination information, etc. recorded and stored in the tag are erased in a lump and then reused. In this case, it is necessary not to delete only the unique identification number of the blood collection tube main body 2 from the tag information. For this purpose, an adapter having two types of tags, ROM and RAM, is used, and unique information for identifying the blood collection tube main body 2 is recorded in the ROM and erased at the time of disposal such as patient ID and blood collection test information. The information to be recorded may be recorded in the RAM.

  By the way, the present invention is not limited to the above-described embodiment, and the adapter according to the present invention can be used by being attached to a vacuum blood collection tube. In that case, assign an identification number to be recorded on the adapter tag for each type of vacuum blood collection tube, and automatically link the type of blood collection tube with patient information and blood collection information. It is possible to automatically read these data later. After the inspection, the information on the tag of the adapter can be deleted, the adapter can be reused, and the vacuum blood collection tube can be discarded.
