The present invention relates to a blood purification apparatus in which display means is disposed in the apparatus main body.

  A hemodialysis device for performing hemodialysis (HD) is a device that treats patients with impaired renal function and diffuses blood and dialysate through a semipermeable membrane such as a dialyzer. It is configured to remove excess water by removing solute by ultrafiltration and ultrafiltration. However, conventionally, many devices equipped with a touch panel monitor for displaying the state of the patient and the apparatus main body during dialysis treatment have been provided.

  Such a touch panel monitor can display the state of the patient or the apparatus main body and can input an operation or display related to hemodialysis treatment (blood purification treatment) to be arbitrarily operated. That is, the touch panel monitor has a screen for displaying the states of the patient and the apparatus main body in real time and has an input means operable to perform a predetermined operation by touching a predetermined position on the screen.

  Further, the touch panel monitor (display means) conventionally has a position facing the operator such as a medical worker (this is referred to as a “first position”) and a position facing the patient (the “second position”). It was possible to rotate between. Accordingly, when a medical worker or the like performs an operation, the touch panel monitor is set to the first position, and when the display of the touch panel monitor is shown to the patient, the touch panel monitor can be rotated to the second position. . In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the conventional blood purification apparatus, when the touch panel monitor (display means) is rotated to the second position and the display of the touch panel monitor is shown to the patient, the patient carelessly operates and an erroneous input is made. There was a risk of it. That is, when the touch panel monitor is directed toward the patient, careless operation on the touch panel monitor is easily performed, and thus the possibility of erroneous input increases.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a blood purification apparatus that can prevent an erroneous input by avoiding an inadvertent operation on an input means by a patient.

The invention according to claim 1 includes a device main body for performing blood purification treatment on a patient, displays the state of the patient or the device main body, and can input an operation or display related to blood purification treatment to be arbitrarily operated. In the blood purification apparatus in which display means having input means is arranged in the apparatus main body, the display means is rotatable between a first position facing the operator side and a second position facing the patient side. In addition, the input means can be operated at the first position while the operation is restricted at the second position, and the first position and the second position are set at an arbitrary angle. It is made possible.

It consists of a possible touch panel monitor.

  According to a fourth aspect of the present invention, in the blood purification apparatus according to the third aspect, the display content of the touch panel monitor is different between the first position and the second position.

  According to the first and second aspects of the present invention, the display means is rotatable between the first position facing the operator side and the second position facing the patient side, and at the first position. Since the input by the input means is restricted at the second position while the input by the input means is enabled, an inadvertent operation on the input means by the patient can be avoided and erroneous input can be suppressed.

  According to the invention of claim 3, since the display means has a screen for displaying the states of the patient and the apparatus main body and is composed of a touch panel monitor that can be operated by touching a predetermined position on the screen, the operation of the input means is restricted. Can be performed more easily.

  According to the fourth aspect of the present invention, the display content of the touch panel monitor is different between the first position and the second position, so that the information necessary for the operator and the information necessary for the patient can be displayed separately. .

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIGS. 1 to 3, the blood purification apparatus according to the present embodiment includes a device body 1 that performs blood purification treatment on a patient, displays the state of the patient or the device body 1, and blood purification. A display unit 2 having an input unit N capable of inputting an operation or display related to treatment as desired is disposed in the apparatus main body 1.

  The apparatus main body 1 includes a blood purification apparatus capable of performing treatment such as hemodialysis (HD), hemodiafiltration (HDF), hemofiltration (HF), or continuous slow blood filtration (CHF), for example, a blood pump. , A fluid replacement pump, a bubble detector, a syringe pump, a liquid crystal monitor, and the like, and a treatment unit 6 (see FIG. 3) that constitutes various devices for performing blood purification treatment on a patient. In this embodiment, the present invention is applied to a dialysis apparatus capable of performing hemodialysis treatment. However, instead of this, it is applied to an apparatus for performing other blood purification treatment (plasma exchange, double filtration plasma exchange, etc.). Also good. Moreover, in this embodiment, the apparatus main body 1 is comprised so that the dialysate can be supplied to the dialyzer connected to the blood circuit, and the drainage liquid from the dialyzer can be discharged.

  As shown in FIG. 4, the display unit 2 includes a screen 2 a that displays the state of the patient and the apparatus main body 1, and includes a touch panel monitor that can be operated by touching a predetermined position on the screen 2 a. Specifically, the patient's vital signs (biological information such as blood pressure) and the progress of water removal during treatment are displayed on the screen 2a, and any position indicated by reference numerals 2aa to 2ae on the screen 2a is displayed. The touch panel is configured to include an input means N for making an input in accordance with the display by touching.

  Further, at the bottom of the screen 2a, there are operation buttons 2b (blood pump operation button 2ba, alarm buzzer stop button) for performing an operation of turning on / off the power as other input means N and an operation on the treatment unit 6 of the apparatus body 1. 2bb and a power button 2bc). The operation button 2b can also be used to input an operation or display related to blood purification treatment to any operation.

  The display means 2 has a first position facing the operator on the front side of the apparatus main body 1 (see FIG. 1) and a second position facing the patient lying on the bed B (see FIG. 2). It is possible to rotate between. That is, when an operator such as a medical worker performs input to the input means N, the display means 2 is set to the first position to improve the operability and to show the display of the display means 2 to the patient. Is configured to rotate the display means 2 to the second position so that the display of the screen 2a can be visually recognized.

  On the other hand, as shown in FIG. 3, the apparatus main body 1 is provided with detection means 3, recognition means 4, and control means 5. The detection means 3 is for detecting the position of the display means 2, and for example, a micro switch, a reed switch, a photo sensor, a rotation angle sensor (rotational position sensor), or the like can be used. In the present embodiment, as shown in FIGS. 5 and 6, a microswitch 7 having a detection unit 7 a is used.

  The microswitch 7 can be rotated in conjunction with the rotation of the display means 2. When the display means 2 is in the first position, as shown in FIG. 5, the microswitch 7 is electrically turned off. ing. Thus, when the display means 2 is rotated to the second position, as shown in FIG. 6, the detection portion 7a interferes with the convex portion 8 formed on the pedestal portion H and is turned on electrically. Yes. As a result, when the display means 2 is in the first position and when it is in the second position, it is possible to electrically turn on and off to detect the position.

The first position where the display unit 2 faces the operator side and the second position where the display unit 2 faces the patient side vary depending on the layout in which the apparatus body 1 is disposed, and thus the apparatus body 1 is installed. when it is configured capable of performing the setting of the first position and the second position. For example, as shown in FIG. 7, the position between the position where the display unit 2 is rotated from the position facing the patient side to θ1 is defined as the first position, and the position between the position where the display means 2 is rotated to the position facing the patient side. In the case of the second position, these θ1 and θ2 can be appropriately set.

  On the other hand, if a rotation angle sensor (which can continuously detect the rotation angle and output information such as a voltage according to the rotation angle and position) is used as the detection means 3, the rotation angle of the display means 2 can be electrically detected. Because it is possible to obtain information with specific information (voltage, etc.), the input restriction stored in the database D and the release condition setting (voltage value as a threshold value) are changed to change the input restriction and the release. The setting position can be changed by simply changing the software setting without adjusting the hardware.

The recognizing means 4 is composed of computing means E electrically connected to the detecting means 3, and can recognize whether the position detected by the detecting means 3 is the first position or the second position. In this embodiment, the microswitch 7 is configured to be able to recognize whether the microswitch 7 is electrically on or off and recognize its position. The calculation means E of the recognition means 4 is configured to be able to exchange information with a predetermined database D. The database D stores various data that can recognize the first position and the second position, and data such as a display form on the display unit 2 at each position. However, the database D may be configured to allow a highly urgent operation even when input is restricted.

Control unit 5, an input unit N and is electrically connected to calculating means E and the display unit 2 of the recognition unit 4, operation of the input means N when the display unit 2 by the recognition means 4 is in the first position The operation with respect to the input means N is restricted when it is in the second position. That is, when the display means 2 is in the first position and faces the operator side, touching the predetermined positions 2aa to 2ae on the screen 2a or operating the operation button 2b, the operation or display related to blood purification treatment On the other hand, when the display means 2 is in the second position and faces the patient, the input by the operation is not accepted.

  Therefore, according to the present embodiment, the display means 2 can be rotated between the first position facing the operator side and the second position facing the patient side, and the input means N Since the input by the operation is allowed at the second position while the input by the operation is restricted at the first position, an inadvertent operation on the input means N by the patient can be avoided and the erroneous input can be suppressed.

  Further, in the present embodiment, when the display unit 2 is in the second position, it is configured not to accept an input by the input unit N. However, in this embodiment, a display that can be input (in the present embodiment, a predetermined on the screen 2a). You may comprise so that position 2aa-2ae) itself may not be performed. As described above, in this embodiment, the display means 2 includes the screen 2a for displaying the state of the patient and the apparatus main body and includes a touch panel monitor that can be operated by touching a predetermined position on the screen 2a. It is possible to make it easier to regulate the operation.

  Furthermore, you may comprise so that the display content of the touchscreen monitor which comprises the display means 2 may differ in a 1st position and a 2nd position. For example, when the display means 2 is in the second position, the display itself that can be input as described above is not performed, but instead information necessary for the patient (for example, vital signs such as blood pressure during treatment, water removal time, etc.) is displayed. It is preferable to do so. Thus, since the display content of the touch panel monitor is different between the first position and the second position, the information necessary for the operator and the information necessary for the patient can be displayed separately.

Further, if the settings of θ1 and θ2 in FIG. 7 can be finely adjusted, for example, unless the screen 2a of the display means 2 is completely directed to the patient side, the input operation to the input means N is not restricted, and even a little screen 2a. by returning to the first position direction it can be set to allow an input to the input unit N. Thereby, in the case of an emergency, even if the staff does not completely return the screen 2a to the first position, the input means N can be input to cope with it.

  Further, when the display means 2 reaches the first position from the second position, the delay time is not allowed to allow the input operation to the input means N immediately but to allow the input operation to the input means N after a certain time has elapsed. You may set it as the structure which can set. In this case, it is possible to allow the input operation to the input means N from the timepiece and the second position detection state of the computer or the like.

Next, the control contents in this embodiment will be described based on the flowchart of FIG.
First, the position of the display means 2 (monitor position) is detected by the detection means 3 (S1), the monitor position is identified by the calculation means E of the recognition means 4, and the display means 2 is the first position facing the operator side. Or in a second position facing the patient (S2). Thereafter, it is determined whether or not there is a request to change the display form of the screen 2a (S3). If there is a request, a display for the patient is displayed on the screen 2a (S4). The display form in 2a is not changed (S5).

  Then, based on the position of the display means 2, it is determined whether or not there is an input operation restriction (input restriction) on the input means N (S6), and the display means 2 is in the second position by the control means 5. When the display means 2 is in the first position, the operation with respect to the input means N is permitted (permission of input) (S8).

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the display means 2 is different from the touch panel monitor (however, it relates to blood purification treatment while displaying the state of the patient or the apparatus main body). The operation or display may be input so as to be arbitrarily operated). As other input means, for example, an LCD monitor touch panel, a sheet key, a switch, a voice input, or the like may be provided in parallel.

The display means can be rotated between a first position facing the operator side and a second position facing the patient side, and the input means can be operated at the first position while the operation is enabled. As long as the blood purification apparatus is configured such that the operation is restricted at the second position, and the first position and the second position can be set at an arbitrary angle, one having a different external shape or another function is added. The present invention can also be applied.
