Description

  The present invention relates to a hemodialyzer management system, and more particularly to a hemodialyzer management system capable of quickly and accurately setting dialysis treatment conditions and the like.

  Hemodialysis is a treatment method in which blood taken from a patient's artery by a blood pump is sent to a dialyzer, and after necessary substance exchange is performed with the dialysate in the dialyzer, the blood is returned. Hemodialysis is usually performed in a fixed facility at regular intervals of 2 to 3 times a week.

  In addition, these daily tasks are performed by doctors or doctors under the direction of doctors, and doctors determine dialysis treatment conditions such as water removal rate, dialysate temperature, blood flow rate, syringe injection speed, and blood pressure upper and lower limits for each patient. Since each set value is manually set for each hemodialysis apparatus according to the instructions described in the medical chart, a considerable number of labors and time are required in a facility having a large number of units. In addition, since the setting value differs for each patient, it is not easy to set accurately and quickly. In addition, the setting method may differ depending on the manufacturer of the hemodialysis apparatus, and much effort is required to accurately set the dialysis treatment conditions for each patient in the number of recovery units.

  As a conventional technique, for example, as described in Patent Documents 1 to 4, management of all patient information such as a weekly treatment schedule and treatment conditions in a medical data processing system, using a medium such as an IC card, There are those that automatically set dialysis treatment conditions with an input device to a hemodialysis monitoring device, and those that automatically set multiple hemodialysis devices by communication with one centralized management system by building a network. However, these systems are expensive.

Further, in the system using the IC card as described above, there is a problem of inputting patient information in the medical data processing system every time of treatment in operation, and a plurality of hemodialyzers are used in the network system. If there is a cost problem such as a large amount of cost for system construction at the time of installation, or if an unexpected trouble occurs in the central control device, it will affect the dialysis treatment of all units There's a problem.

In this storage (registration) of patient information, it is possible to store patient information of a plurality of persons, and a dedicated screen for registering information is provided. Examples of dialysis treatment conditions as patient information include syringe injection rate (replacement fluid injection rate), dialysate temperature set value, alarm width, and the like. As the treatment schedule information, for example, weekly schedule information can be used, and it is possible to input a plurality of dialysis treatment schedules per day. The patient information storage unit 102 and the treatment schedule information storage unit 103 preferably have a function of associating registered patient information with weekly schedule information, for example.

  In the hemodialyzer management system 101 according to the present embodiment, based on the dialysis treatment condition as the patient information stored in the patient information storage means 102 and the treatment schedule information stored in the treatment schedule information storage means 103. Thus, operating condition setting means 104 capable of automatically or manually setting the operating conditions of the hemodialysis apparatus 100 is provided. As described above, for example, a function for managing a weekly schedule of a patient in hemodialysis treatment is provided, and operating conditions can be set manually based on displayed patient information before dialysis treatment. In addition to the information, a calendar timer mounted in the apparatus can be used to make it possible to automatically set the operation conditions for each patient. With respect to the setting by the operating condition setting means 104, the background color of the screen on which the operating condition can be displayed can be set to a different color before and after the setting. For example, when a dialysis treatment condition is automatically set based on a calendar timer mounted on the apparatus, the background color of the screen is set to a registered color so that it can be identified at a glance. In this way, it is possible to identify at a glance that the appropriate setting has been completed.

  In the hemodialyzer management system 101 according to the present embodiment, operating condition confirmation means 105 for confirming the operating conditions of the hemodialysis apparatus 100 set by the operation condition setting means 104 is provided. This operating condition confirmation means 105 can confirm whether or not the above setting has been performed properly, and can reliably prevent the occurrence of an erroneous setting.

The series of information is displayed on the display screen 107.

  In the hemodialyzer management system 101 according to the present embodiment, treatment information about dialysis before and after dialysis or during dialysis is stored as specific patient information, and / or specific conditions (for example, blood pressure conditions, etc.) Specific information / condition storage means 108 is stored. Moreover, in this embodiment, the past information storage means 109 which memorize | stores the patient's past treatment information is also provided. The information by the specific information / condition storage means 108, the information by the past information storage means 109, and the operating conditions of the hemodialysis apparatus 100 set by the operation condition setting means 104 are compared by the comparison means 110, and the set operation is set. The appropriateness of the condition is judged for each patient. When it is determined that the set operating condition is not appropriate beyond the range as a result of checking the past information such as the minimum speed and the maximum speed in the past treatment information, for example, by the alarm / caution transmitting means 111, An alarm or caution signal is emitted. It is preferable that the warning or caution can be displayed on the display screen 107 based on this signal.

  For example, as the patient information to be compared, it is preferable to store a plurality of past treatment information and have a function of calling and comparing by a representation method such as a graph. If the signs of blood pressure reduction etc. are patterned, based on this past treatment information, set and register the time width and change width for the specified information (for example, venous pressure value, maximum blood pressure value, etc.) Thus, when the set change width is exceeded, it is possible to provide a function of calling attention that a sign of change appears in the patient state. For example, when there is a change of 30 mmHg or more as the maximum blood pressure value in 5 minutes, a warning can be issued as a sign of a decrease in blood pressure.

It is determined whether it is within the set range. When not in the proper setting range, an alarm or caution signal is transmitted by the alarm / caution transmitting means 111 as described above.

  By comparing with the estimated appropriate setting range, erroneous setting can be prevented more reliably. For example, manual dialysis treatment condition changes with patient conditions during dialysis treatment are not uncommon. In this case, various attempts have been taken for each facility in order to prevent erroneous setting during manual setting. However, situations in which manual dialysis conditions are changed may be when some unexpected situation occurs. In such a state, for the purpose of preventing erroneous setting, for example, when the setting range estimated from past treatment information, or when the setting range actually used in the past is exceeded, or less Can be given a function to prevent misconfiguration by giving attention.

  In the hemodialysis device management system 101 according to the present embodiment, output means 113 for outputting at least one of stored patient information and treatment schedule information is provided. The information output by the output means 113 can be input to other devices or systems 114 as sharable information, for example. This output and input may be performed as necessary. Examples of the other device / other system 114 include other dialysis-related devices or dialysis treatment information processing systems as described above.

  As described above, the hemodialysis apparatus management system 101 is incorporated in the hemodialysis apparatus 100 itself, and the operating conditions of the hemodialysis apparatus 100 are quickly and accurately set as the optimal operating conditions for each patient based on each information. The By applying this system, management of dialysis patients and nursing work are facilitated, and prevention of erroneous settings can be reliably achieved.
