Description

  The present invention relates to an adapter attached to a blood collection tube outer tube used when collecting blood, and a blood collection system for attaching the adapter to the blood collection tube outer tube to collect blood.

  Conventionally, in a medical institution, blood collected from a patient is housed in a container such as a test tube and is transported to an inspection institution that performs an inspection together with an inspection request form that describes the inspection contents. And in the inspection organization, it inspected based on the inspection content described in the inspection request form.

  Here, in a medical institution, in order to identify which patient blood is collected from, a patient's name, a patient ID assigned to each patient, and the like are attached to a container containing blood. It was. For example, the name of the patient and the patient ID assigned to each patient are directly written on the container, or a label describing the name of the patient is attached to the container (for example, see Patent Document 1).

JP 2001-272916 A

  By the way, after collecting blood, if the patient name or patient ID is directly written in the container containing the collected blood or if a label with the patient name or patient ID is pasted, the patient name May be mistaken, which may result in misunderstanding of patients and blood. In addition, even when a patient's name is written in the container in advance before blood is collected, there is a possibility that the container for storing the collected blood may be mistaken and an accident involving the patient or blood may occur. Furthermore, a part of the patient name or the like described may disappear, and the written characters may be difficult to read.

  Here, when blood is collected in a container, a cylindrical blood collection holder having an injection needle mounting portion for mounting an injection needle at one end is used. Note that the injection needle is inserted through the injection needle mounting portion so that both ends of the injection needle are located inside and outside the blood sampling holder. As a specific procedure for blood collection, first, a container whose pressure is reduced in the tube is inserted into the blood collection holder while the injection needle is inserted into the blood vessel of the patient. Next, the blood of the patient is collected in the container by penetrating the end of the blood collection holder of the injection needle through a plug that closes the opening of the container.

  When collecting blood using a blood collection holder, conventionally, after collecting blood in a container, replace the needle of the blood collection holder and reuse the blood collection holder to collect blood from another patient in a new container. Was done. However, in recent years, when blood is collected by exchanging the injection needle, the blood of the blood collection holder can be contaminated because the blood of the previous patient may adhere to the injection needle mounting part when the used injection needle is removed. There is a view that the possibility of causing blood-borne infection as a cause cannot be denied. Specifically, when the needle is replaced with a new one, the container is inserted into the blood sampling holder, and blood is collected from another patient, the blood of the patient before adhering to the injection needle mounting portion passes through the injection needle. It is conceivable that the blood flows back into another patient's blood vessel.

  Although this possibility is considered to be extremely low, the possibility of blood-borne infections cannot be completely ruled out, so the reuse of blood collection holders was prohibited and the blood collection holder was required to be disposable.

  FIG. 3 is a diagram illustrating an example of the blood collection tube according to the first embodiment and an adapter connected to the blood collection tube at the time of blood collection. As shown in FIG. 3, the blood collection outer tube 20 includes a cylindrical blood collection tube insertion portion 22 having a closed portion at one end and an opening at the other end. A closed portion of the blood collection tube insertion portion 22 is provided with an injection needle mounting portion 24 to which an injection needle 26 is mounted, and a plurality of threads 20 a are formed outside the blood collection tube on the opening side of the blood collection tube outer tube 20. A cylindrical shape is formed along the outer wall of the cylinder 20.

  The injection needle 26 is attached to the blood collection tube 20 so that one end of the injection needle 26 penetrates the injection needle attachment portion 24 and is located in the blood collection tube insertion portion 22.

  The adapter 27 has a cylindrical wall portion, and a plurality of lugs 27a screwed with the screw thread 20a are formed on the inner wall on one end side of the cylindrical wall portion, and the cylindrical wall portion is formed. A substantially annular flange 27b is formed at the other end of the lip for hooking a finger during blood collection.

  In addition, a coiled antenna 28 that transmits and receives information to and from the IC tag 8 is embedded in two opposing portions of the cylindrical wall portion of the adapter 27.

  Here, the communicable distance at which the antenna 28 can transmit / receive information to / from the IC tag 8 is adjusted to a certain range. That is, when the adapter 27 is connected to the blood collection outer tube 20 and the blood collection tube 2 is inserted into the blood collection tube insertion portion 22 through the space 29 formed inside the cylindrical wall portion of the adapter 27, the collection is performed. The communication distance is adjusted to such an extent that information can be transmitted / received to / from the IC tag 8 accommodated in the accommodating portion 4 of the blood vessel 2.

  Blood collection is performed after the external end of the blood collection tube of the injection needle 26 attached to the blood collection tube 20 is inserted into the patient's blood vessel with the adapter 27 connected to the blood collection tube 20. The blood collection tube 2 is inserted into the blood collection tube insertion portion 22 through a space 29 formed inside the cylindrical wall portion of the adapter 27.

  FIG. 4 is a block configuration diagram of the blood collection system according to the first embodiment. As shown in FIG. 4, the blood collection system includes an antenna 28 that transmits and receives information to and from the tag writing device 30 and the IC tag 8. The antenna 28 is embedded in the cylindrical wall portion of the adapter 27 (see FIG. 3).

  As shown in FIG. 4, the tag writing device 30 includes a data control unit 32 that controls data in the tag writing device 30. The data control unit 32 is connected to a bar code reader 34 that reads information recorded in the bar code and an IC tag writer 36 that writes information read via the bar code reader 34 to the IC tag 8. Further, the data control unit 32 converts the data storage unit 38 for storing information read through the barcode reader 34 and the patient ID (identification information) into an inspection center ID (examination institution identification information). An ID conversion table 40 that stores an ID conversion pattern to be connected is connected.

  The ID conversion table 40 stores an ID conversion pattern for converting a patient ID used in each medical institution into an inspection center ID used in the inspection center. That is, in each medical institution, the patient ID used in each medical institution is used as information for identifying the collected blood. Therefore, in an examination center where blood requested for examination is carried in from a plurality of medical institutions, in order to appropriately manage the carried blood, the patient ID used for identifying the blood in the medical institution is used. Instead, it is necessary to assign an inspection center ID used in the inspection center. Therefore, an ID conversion pattern for converting a patient ID into an examination center ID is stored in the ID conversion table 40. Note that the conversion pattern stored in the ID conversion table 40 includes a conversion pattern for adding a facility number assigned to each medical institution and a reception date to the patient ID.

  Next, processing in the blood collection system according to the first embodiment will be described with reference to the flowchart of FIG.

  First, as shown in FIG. 6, the adapter 27 is connected to the opening side of the blood collection tube 20. Here, the adapter 27 is connected by screwing a lug 27a formed on the inner wall of the cylindrical wall portion of the adapter 27 into a screw thread 20a formed along the outer wall of the blood collection tube outer tube 20. Is called.

  Next, in a state where the adapter 27 is connected to the blood collection tube outer tube 20, the external end of the injection needle 26 attached to the blood collection tube outer tube 20 is pierced into the patient's blood vessel. Then, the patient ID recorded in the barcode is read (step S10), and the read patient ID is stored in the data storage unit 38 (step S11). For example, when a wristband with a barcode that records a patient ID for identifying a patient is wound around the wrist of the patient from whom blood is collected, the wristband is wrapped around the patient's arm. The patient ID recorded in the barcode is read through the barcode reader 34 and stored in the data storage unit 38.

  Next, in order to convert the patient ID into the examination center ID, the conversion pattern stored in the ID conversion table 40 is referred to (step S12). For example, in the medical institution A, a 4-digit code such as A123 is used as the patient ID, and the 12-digit including the facility number assigned to each medical institution and the blood reception date is used as the test center ID. Suppose you use a code. Therefore, in such a case, the conversion pattern stored in the ID conversion table 40 is referred to a conversion pattern for converting a patient ID consisting of a 4-digit code into an examination center ID consisting of a 12-digit code. To do.

  Next, based on the conversion pattern referenced in step S12, the patient ID stored in the data storage unit 38 is converted into an examination center ID (step S13). That is, based on the referred ID conversion pattern, for example, a blood number represented by a 4-digit code and a facility number composed of a 4-digit code representing the medical institution A in a patient ID composed of a 4-digit code of the medical institution A Is added to the inspection center ID consisting of a 12-digit code.

  Next, the inspection center ID converted in step S13 is transmitted from the IC tag writer 36 via the antenna 28 (step S14). That is, the test center ID data is transmitted to the space 29 formed inside the cylindrical wall portion of the adapter 27 via the antenna 28, and the blood collection tube insertion portion of the blood collection outer tube 20 to which the adapter 27 is connected. When the blood collection tube 2 is inserted into 22, the test center ID can be written in the IC tag 8 accommodated in the accommodating portion 4 of the blood collection tube 2.

  Next, the blood collection tube 2 is inserted into the blood collection tube insertion portion 22 of the blood collection tube outer tube 20 through the space 29 formed inside the cylindrical wall portion of the adapter 27, and blood is collected from the patient. That is, the blood collection tube 2 is inserted into the blood collection tube insertion portion 22 of the blood collection tube outer tube 20 until the end portion of the injection needle 26 inside the blood collection tube insertion portion 22 penetrates the lid portion 6. Here, the opening part of the container 4 of the blood collection tube 2 is closed by the lid part 6 in a decompressed state. Therefore, blood is collected from the patient due to the pressure difference by passing the end of the injection needle 26 inside the blood collection tube insertion portion 22 through the lid portion 6.

  In addition, when the blood collection tube 2 is inserted into the blood collection tube insertion portion 22 of the blood collection tube outer tube 20 to which the adapter 27 is connected for blood collection, the converted test center ID is stored in the storage portion of the blood collection tube 2. 4 is written in the IC tag 8 accommodated in the terminal 4 (step S15).

The communication distance is adjusted so that information can be transmitted / received to / from the IC tag accommodated in the accommodating portion. Accordingly, information is not transmitted / received to / from the IC tag of the blood collection tube prepared around the blood collection tube outer tube. Therefore, information can be written only to the IC tag of the blood collection tube inserted into the blood collection tube insertion portion of the blood collection tube outer tube for blood collection.

  Further, according to the first embodiment, the patient ID assigned to the patient in each medical institution is converted into the inspection center ID and written to the IC tag. Therefore, in an inspection center into which blood is carried in, blood can be managed quickly and easily using an IC tag.

  Further, according to the blood collection system of the present invention, when the blood collection tube is inserted into the blood collection tube insertion portion of the blood collection tube outer tube, the information read by the barcode reader is provided in the IC collection portion of the blood collection tube Is written on. Therefore, when blood is collected, information for identifying the collected blood can be written in an IC tag provided in the storage portion of the blood collection tube in which the collected blood is stored. Accidents can be reliably prevented.

  In addition, the antenna provided on the wall of the adapter allows information to be transmitted to the IC tag provided in the blood collection tube storage portion when the blood collection tube is inserted into the blood collection tube insertion portion of the blood collection tube outer tube. Transmission and reception are possible. Therefore, information for identifying blood can be written only in an IC tag provided in a storage portion of a blood collection tube for storing blood collected from a patient.

  Further, the identification information used in the blood sampling organization is converted into the inspection organization identification information used in the testing organization, and is written in the IC tag provided in the storage portion of the blood collection tube. Therefore, even in the case where blood is carried in from a plurality of institutions, the laboratory can quickly and easily manage blood based on the unified laboratory identification information.

  Next, a blood collection system according to the second embodiment will be described. As in the first embodiment, the outer tube of the blood collection tube according to the second embodiment is replaced with an end of the outer tube of the blood collection tube instead of connecting to the adapter using a screw thread formed on the outer wall.
