Description

  The present invention can reduce the burden on the patient at the time of blood collection, can prevent mistakes in the patient and blood collection tubes, and the blood collection work result can be converted to HIS (Medical Information System) or LIS (Test Information System). The present invention relates to a blood sampling work table that can be reflected.

In blood testing departments at hospitals, clinics, and other medical institutions, blood collection workers (nurses, etc.) collect blood from patients, store the collected specimens in blood collection tubes, and transfer them to the laboratory. . In blood tests, various types of blood collection tubes are prepared according to the blood test items, and usually, a plurality of types of tests are performed on one patient at the same time. Therefore, a plurality of types of blood collection tubes are prepared for one patient. In the blood collection room, it is natural to handle a large number of patients, and each blood collection tube is attached with a label printed with a barcode such as an order number, and also in a tray for storing these blood collection tubes for each patient. A label printed with a tray number barcode for referring to the stored blood collection tube is attached. Furthermore, a blood collection reception slip on which a barcode such as a reception number is printed is issued to the patient. At the time of blood collection work, the contents of these labels and reception slips are read by an optical device such as a barcode reader so that the patient and blood collection tube are not mistakenly taken. As techniques for automating such blood collection work and supporting the blood collection work, there are techniques shown in Patent Documents 1 and 2.

  These techniques of Patent Documents 1 and 2 solve the problem of unfair waiting time of patients when blood collection work is performed in parallel on a plurality of blood collection tables, in addition to realizing the automation of the blood collection work. I am doing so. In other words, when blood collection work is performed in parallel on a plurality of blood collection tables, the time required for blood collection varies depending on the skill level of the blood collection operator, the patient's constitution, etc. There is a problem in that an unfair feeling arises among blood collection workers in the entire blood collection table. Therefore, in the techniques of Patent Documents 1 and 2, when there is an assignment request from a blood collection operator, the unfairness is eliminated by sequentially assigning patients to a blood collection table. The patient is called by displaying the blood collection receipt number on a call display installed on the blood collection table.

  Also, as shown in Patent Document 3, a blood collection table installed in a blood collection chamber is known to incorporate a blood collection preparation device, but is basically installed to perform blood collection work professionally. Is. That is, on the blood collection table, a tray for each patient storing a plurality of types of blood collection tubes is prepared for placement, and an arm on the side where the patient collects blood is placed. Furthermore, a rack in which blood collection tubes after collecting the collected specimens are arranged in an upright state is also placed. Before blood collection, read the barcode of the patient's blood collection receipt and the tray in which the blood collection tube is stored with an optical device such as a barcode reader. To make sure. This confirmation work is also performed at this blood collection table.

Furthermore, as shown in Patent Document 4, a blood collection chair in which a conventional patient sits in front of a blood collection work table is tilted from a substantially horizontal state and a substantially horizontal state by interlocking a backrest base and a headrest base. It is comprised so that it may be in a state, and it is made unnecessary to operate a backrest base and a headrest base individually. This makes it possible to take a posture to quickly lower the head in a substantially horizontal state even in an emergency when the patient feels unwell during blood collection, and when collecting blood from the right arm and from the left arm So that you can respond quickly even when you change the sitting direction.

  In the techniques shown in Patent Documents 1 and 2, when the tray is carried into the blood collection table, the barcode on the label attached to the tray is read by an optical device such as a barcode reader, and the read information is read by a higher-level medical computer. Order (inspection) information is acquired online. Then, the patient is called. Calling is performed by displaying the blood collection reception number of the patient on a call display device such as an LED installed on the blood collection table. However, when using multiple blood collection tables, it is necessary to display the number including the identification symbol for each blood collection table, and if the patient is inadvertently misunderstood that he called the next blood collection table. I went to the next blood collection table.

In addition, the conventional blood collection table is set up for professional blood collection work. Labels affixed to the tray with a barcode reader prepared on the blood collection table and the blood collection receipt slip held by the patient. The contents are read with an optical device to prevent mistakes in taking the patient and blood collection tube. However, as described above, it is necessary to inquire and collate online as described above. It had to be an environment where it could be done.

  Furthermore, depending on the physical condition of the patient, blood sampling for the examination may not be performed even though the examination instruction is given. For this reason, the blood collection operator manually reflects in the HIS and LIS the information on the specimen-accommodating blood collection tube where blood was actually collected and the empty blood collection tube where blood was not collected. This was one of the causes of delaying blood collection work.

Furthermore, in the prior art including the techniques described in Patent Documents 1 to 4, the content of the blood sampling operation has not been recorded. Therefore, it is not possible to search retrospectively for information related to blood collection work such as blood collection date and time, blood collection worker, patient, type of collected blood collection tube, inspection item, type of blood collection tube actually collected, statistical data and When a medical error accident occurred, it could not be used for analysis.

  The present invention has been improved and removed in view of the above-described problems, can reduce the burden on the patient at the time of blood collection, can prevent mistakes in the patient and blood collection tubes, and blood collection work results We are going to provide a blood sampling work table that can be reflected in HIS and LIS.

On the left side of the blood collection booth A, a blood collection tube preparation device J is arranged. The blood collection tube preparation device J selects a necessary blood collection tube from a plurality of types of blood collection tubes based on the order (examination) information from the HIS, and attaches a label on which the order (examination) information is printed to the patient. Each is stored in one tray 1 and supplied to each booth.

  In the blood collection booths A to E, the left side partition plate 2 and the front partition plate 3 are arranged in an L-shape, and the work situation in the blood collection booth and the patient's face are arranged from the waiting room side. The inspection items and the type of blood collection tube are not directly visible. The two partition plates 2 and 3 are provided with a space between the ceiling on the upper end side to eliminate a feeling of pressure so that weight reduction and layout change / assembly can be easily performed. It is molded with a synthetic resin plate. The partition plates 2 and 3 can protect patient privacy. In the blood collection booth, a blood collection chair 4 and a blood collection work table 7 having a concave portion 5 for placing a tray 1 storing blood collection tubes prepared for each patient and an operation display unit 6 are disposed. ing. Further, the front partition plate 3 is provided with a call display device 8 comprising a monitor with a color display function having two front and back surfaces arranged facing the waiting room side and the blood collection booth.

  The blood collection chair 4 includes armrests 9A and 9B for blood collection that can be moved up and down on the left and right sides, and a rotary seat 10 for the seat. The armrests 9A and 9B can be moved up and down remotely by only a button operation by obtaining a driving force from an electric motor through a worm gear, a screw shaft, and the like.

The operation display unit 6 of the blood collection worktable 7 includes a touch panel unit and a display unit that displays a patient ID, a type of blood collection tube, an examination item, and the like. Further, the recess 5 of the blood sampling work table 7 is provided with a window (not shown) for reading tray information on the inner side surface thereof. This window is for reading the information of the RF-ID tag built in the tray 1 or the barcode information of the label attached to the outer surface of the tray 1. Therefore, an optical reader such as an RF-ID tag reader / writer and / or a barcode reader is installed at the position facing the window inside the blood sampling work table 7.
The RF-ID tag built in the tray 1 may be a separate type that is inserted into the tray 1 in the blood collection tube preparation device, instead of being integrated with the tray 1. As the RF-ID tag, a commercially available general-purpose product may be used. As a special type, an RC timer circuit or other means that when a certain amount of time has passed, the accumulated power supply capacity is lost due to discharge, and all written information is automatically erased. It is also possible to prevent personal information from leaking by using a type that is restricted.

Furthermore, the call display device 8 displays the waiting order for blood collection, and is set to display the same color display or the same mark as the color or unique mark of the blood collection reception slip 11 shown in FIG. . Naturally, the colors of the call display devices 8 between the booths are displayed in different colors or marks.

  Next, an operation mode of the blood collection work support system configured as described above will be described. First, in each blood collection booth A to E, as shown in FIG. 3, when the blood collection worker approaches the blood collection work table 7, authentication data transmitted from the electronic authentication key 12 </ b> A handed to the blood collection worker in advance is The electronic authentication lock 12B connected to the CPU of the blood sampling work table 7 automatically receives and confirms the authentication, and if it is OK, the blood sampling work table 7 can be operated. The authentication of the blood collection operator can also be performed by a face authentication method using a CCD camera 13, as shown in FIG.

On the other hand, in the blood collection tube preparation apparatus J, a blood collection tube necessary for a patient to collect blood is prepared. This is a conventionally known device, and a necessary blood collection tube is selected from a plurality of types of blood collection tubes based on order (inspection) information from the HIS, and a label on which order (inspection) information is printed is attached. In addition, each patient is stored in one tray 1. A bar code label on which a patient name of the stored blood collection tube, blood collection information, and the like is written is attached to the side surface of each tray 1. In addition, in the RF-ID tag built in the tray 1, the name of the stored blood collection tube, blood collection information, and the like are written in a wireless communication system. Thereafter, the tray 1 is supplied to each booth through the stockyard FS. The supply of the tray 1 is performed by a tray supply transfer device F that is intermittently driven in response to requests from the blood collection booths A to E.

When the tray 1 is transported to each booth, the blood collection operator at each booth manually removes the tray 1 from the transport device F and places it on the recess 5 of the blood sampling work table 7. The recessed portion 5 is provided with a tray information reading window, through which the RF-ID tag information built into the tray 1 and / or the barcode information attached to the outer surface of the tray is wirelessly transmitted. Reading is automatically performed by a communication method or an optical method. In the case of using an RF-ID tag, the bar code may be used as a backup when the RF-ID tag fails. The read information is displayed on a monitor on the operation display section of the blood collection worktable 7. In FIG. 3 and FIG. 4, it is displayed on the multi-monitor 6A.
In the figure, reference numeral 6B denotes a touch panel of the operation display unit. The blood collection operator touches the touch panel 6B to perform various operations and instructions. Further, the read information on the tray 1 is sent to and stored in a built-in CPU.

Further, the number of the patient is displayed on the call display device 8 based on the read information of the tray 1. The patient collates the color or mark of the call display device 8 displayed in the waiting room with the color or mark of the blood collection receipt slip 11 held by the patient, confirms the number, and is the same if both match. Enter the blood collection booth with color or mark. Then, the blood collection acceptance form 11 is handed to the blood collection operator. The blood collection operator reads the barcode of the received blood collection receipt slip 11 with a barcode reader or the like, and displays it in parallel with the information on the tray 1 on the multi-monitor 6A of the operation display unit so that visual confirmation can be performed. At the same time, the CPU records are saved. As a result, it is possible to collate the patient with the tray 1 off-line, and there is no need to inquire online and download information as in the past, and it is very convenient because it can be performed instantly and automatically at the blood sampling site. is there. When the blood collection acceptance sheet 11 is of a wireless communication system using an RF-ID tag, it is possible to automate all the operations except for the removal of the tray 1.

  After confirming the collation between the patient himself and the tray 1, the blood collection operation is started after the patient is seated on the blood collection chair 4. The patient sits on the blood collection chair 4 from the lateral direction, which is a wide space area free from obstacles, and then rotates the rotary seat approximately 90 degrees so as to face the blood collection operator in the front. Then, the armrest 9A or 9B is moved up and down to adjust the height so that the height matches the patient's body shape. As a result, the patient can receive blood by placing his arm on the armrest 9A or 9B in an easy posture.

When the preparation of the patient is completed and the patient enters a standby state, the blood collection operator takes out the blood collection tube in the tray 1 and sequentially performs the blood collection operation. After blood collection, the blood collection tube containing the sample is stored in a state where it is stood on an empty rack (not shown) prepared in advance. Note that the empty rack may be prepared by manually taking out a blood collection operator from the outlet K provided on the terminal side of the transfer device G. In this way, after all the blood collection operations are completed, the blood collection tube storage rack may be loaded from the loading port L to the transport device H. On the other hand, the empty trays 1 are stacked in an empty state, and when a predetermined quantity is accumulated, the blood collection operator puts it in the input hopper M of the blood collection tube preparation device J and collects it.

In addition, the rack in which the blood collection tubes after specimen storage are stored in a vertically placed state is obtained by blood collection result recognition means (optical means) such as a barcode reader at a station P provided in the middle of the transport path of the transport device H. The label information attached to the blood collection tube is automatically read. The read information is transmitted to the HIS and the LIS. The HIS specifies the type of blood collection tube for which blood collection could not be performed even though a blood collection instruction has been issued, and is useful for subsequent treatment. On the other hand, in the LIS, medical expenses are not charged for blood collection items that could not be collected.
The specimen-collected blood collection rack that has passed through the station P is transported to the inspection process by the transport device H, and various inspections of the specimen after blood collection are performed.
The blood collection result recognition means may be provided on the blood collection work table 7 in the blood collection booth. In this case, the blood collection result can be reflected in the HIS and LIS immediately after blood collection.

By the way, the CPU built in the blood collection work table 7 performs the blood collection operation described above, the blood collection date and time, the blood collection operator, the patient, the type of the collected blood collection tube, the inspection item, the type of the collected blood collection tube, and the blood collection. The history such as the absence information of the patient is stored as data. These data are used as statistical materials or used as analysis data for medical errors.
In addition, since each blood collection work table 7 has a built-in CPU in this manner, even when a blood collection operator is switched between a plurality of blood collection booths, it is possible to automatically record and display the information through an automatic authentication mechanism. There is no need for online registration, registration and permission. For this reason, when blood collection work at an inexperienced blood collection booth is overdue, it is possible to replace it with a veteran blood collection worker freely on the site side. It is possible to carry out a smooth blood collection operation as a whole.

  By the way, this invention is not limited to embodiment mentioned above, A suitable change is possible. For example, when the blood collection work table 7 is configured to be freely movable by providing a caster, blood is collected at the bedside of an inpatient ward, blood is collected in a blood collection room, blood is collected in an emergency ICU can do.
