Description

  The present invention relates to an abnormality warning system and an abnormality warning method for a negative pressure treatment apparatus.

  Conventionally, as a negative pressure treatment device, a treatment device that aspirates body fluid exuding from a wound part and discharges it from the inside of the cover sheet while keeping the inside of the cover sheet covering the wound part such as skin ulcer or tissue defect in a negative pressure state It has been known. According to such a negative pressure treatment device, necrotic cells, bacteria, and the like can be sucked and removed from the wound part, and blood flow in the wound part can be promoted by the negative pressure, thereby enhancing the therapeutic effect of the wound part.

  By the way, in the treatment of such a wound part, it is necessary to continuously operate the negative pressure treatment apparatus, and the period required for the treatment often takes several months depending on the initial symptoms of the wound part and the progress of healing. . For this reason, it is necessary to assume that some abnormality may occur in the operating state of the negative pressure treatment apparatus during the treatment. Usually, the negative pressure treatment apparatus is provided with warning means such as a warning light and a warning buzzer to notify that an abnormality has occurred in the operation state.

  However, in a long-term treatment period, it is also assumed that an abnormality occurs in the operating state of the negative pressure treatment apparatus in a situation where a doctor or a nurse is not nearby. In that case, it is not always possible to inform the doctor or nurse of the occurrence of the abnormality quickly and surely with these warning means, and if the patient himself does not take action to inform the occurrence of the abnormality, There is a risk that a considerable amount of time may be required until a doctor or nurse notices the occurrence of an abnormality.

  Therefore, as means for notifying the patient of the occurrence of an abnormality, a multi-function call switch (Patent Document 1) that can handle various calling modes, and a nurse call system capable of individual communication with each nurse (Patent Document 2) Is disclosed. Adopting these technologies enables patients to take actions to inform doctors and nurses about the occurrence of abnormalities, even for patients with symptoms that are so severe that they cannot move freely. .

  However, in the field where the negative pressure treatment device is actually used, there are cases where the negative pressure treatment device is operated without the warning means functioning for reasons such as consideration for the patient. For example, it may be used for treatment in a time zone after the light-out time elapses or treatment in a shared room where a plurality of patients are hospitalized. If an abnormality occurs in the operating state of the negative pressure treatment device in such a situation, a considerable time may pass without the patient himself / herself noticing the occurrence of the abnormality, and the response to the abnormality may be significantly delayed.

  When an abnormality occurs in the operating state of the negative pressure treatment apparatus, a situation in which the treatment that should be performed normally is not performed normally occurs. If such a situation continues for a long time, the risk of developing an infectious disease or the like increases, and the symptoms of the wound may be worsened. Therefore, in order to avoid such a situation, it is possible to perform the optimum response according to the content of the abnormality that has occurred as quickly as possible and to restore the operating state of the negative pressure treatment device to the normal state as soon as possible. desirable.

  The negative pressure treatment device 1 is a device that discharges fluid from the inside of the covering sheet S while keeping the inside of the covering sheet S covering the wound portion W such as a skin ulcer or a tissue defect in a negative pressure state. The wound part W is provided with a porous pad P that is permeable to air and fluids such as body fluids exuded from the wound part W, and a covering sheet S is attached so as to cover the wound part W and the pad P. Has been. The negative pressure treatment device 1 includes a suction means 2 for sucking fluid from the inside of the covering sheet S through the suction channels 2a and 2b, and a liquid (wound) contained in the fluid discharged from the inside of the covering sheet S by the suction means 2. And a container 3 for storing a body fluid or the like drained from the portion W).

  The suction means 2 is composed of, for example, a diaphragm vacuum pump, a tube pump, a vane pump, etc., and keeps the inside covered with the coating sheet S in a negative pressure state and sucks fluid. In the present embodiment, the inside of the container 3 is decompressed by sucking the air in the container 3 through the suction flow path 2a, and the body fluid oozed from the wound part W is sucked through the suction flow path 2b drawn from the inside of the covering sheet S. To do. For each suction channel 2a, 2b, a flexible tube or the like without air leak is used.

  The container 3 accommodates the liquid contained in the fluid sucked by the suction means 2 (drainage fluid such as body fluid oozed from the wound part W). The container 3 is preferably made of a transparent material such as glass or transparent resin from the viewpoint of internal visibility, and considering a waste disposal process, etc., a resin container that is inexpensive and easy to handle as a consumable can be used. More preferably it is used. Further, open end portions of the suction channels 2 a and 2 b are disposed in the internal space of the container 3, and these suction channels 2 a and 2 b are connected to the suction means 2 from the inside of the covering sheet S through the internal space of the container 3. It is comprised so that it may communicate.

  The detection unit 11 is means for detecting an abnormality related to the operating state of the negative pressure therapy apparatus 1. In the present embodiment, the fullness detection sensor 111 for detecting the full state of the container 3 in which liquid such as drainage is stored, the pressure sensor 112 for measuring the inner pressure covered with the covering sheet S, and the pressure in the container 3 A plurality of detectors 11 including a pressure sensor 113 that measures the above are provided. With regard to the operating state of the negative pressure treatment device 1, the fullness detection sensor 111 detects an abnormality that makes the continuous operation of the suction means 2 impossible. The pressure sensors 112 and 113 detect an abnormality (for example, an air leak occurrence or excessive negative pressure state) related to the inner pressure state covered with the covering sheet S.

  The control unit 12 is means for specifying the abnormality content based on the information related to the abnormality detected by the detection unit 11. The control unit 12 is configured by a central processing unit (CPU) or the like in which a program for causing the negative pressure treatment device 1 to perform a desired operation is incorporated. In addition to specifying abnormal contents regarding the operation state of the negative pressure treatment device 1, for example, It consists of suction storage unit 2, detection unit 11, and operation control of transmission unit 13 and warning unit 4 (for example, warning lamp 4a and warning buzzer 4b) to be described later, or an information storage medium such as an internal memory, a magnetic disk, an optical disk, etc. Information processing using the information stored in the storage unit 15 is executed.

  In the present embodiment, information corresponding to the detection signals from the sensors 111 to 113 is stored in the storage unit 15 in advance, and the detection signal is transmitted from the detection signal transmitted from any sensor to the control unit 12. By performing information processing for acquiring information to be performed, the abnormal content occurring in the operating state of the negative pressure treatment device 1 is specified. For example, the information corresponding to the detection signal from the full detection sensor 111 corresponds to an abnormality in which the continuous operation of the suction unit 2 is impossible. In addition, the information corresponding to the detection signals from the pressure sensors 112 and 113 distinguishes between the case where the measured value exceeds the upper limit value of the threshold range according to the operation setting and the case where the measured value falls below the lower limit value. What is necessary is just to respond | correspond to an air leak generation | occurrence | production and an excessive negative pressure state, respectively.

  The transmission unit 13 is means for transmitting warning information corresponding to the abnormality content specified by the control unit 12. The transmission unit 13 is configured with, for example, an external communication controller or the like, and enables communication with the reception unit 14 installed outside the negative pressure therapy apparatus 1. In the present embodiment, it is desirable that the transmitter 13 adopts a wireless communication system that is less susceptible to routing restrictions such as wiring, but a wired communication system may be employed according to the usage environment of the negative pressure treatment device 1. .

  In the present embodiment, the information acquired from the storage unit 15 by the information processing performed by the control unit 12 is configured to be used as warning information as it is. Moreover, the transmission part 13 is comprised so that warning information may be transmitted based on the processing signal transmitted from the control part 12 by using the detection signal from the detection part 11 as a trigger. Accordingly, accurate warning information can be automatically transmitted from the transmission unit 13 to the reception unit 14 while avoiding the complexity of the information processing program incorporated in the control unit 12. Therefore, it is not necessary for the patient himself to take action to inform the occurrence of the abnormality.

  The receiving unit 14 is means for receiving warning information transmitted from the transmitting unit 13. For example, the receiving unit 14 includes a plurality of portable receiving terminals 142 that receive warning information through an existing relay device 141 that is employed in a nurse call system or the like, and informs a doctor, nurse, or the like of the warning information. It has a function as information transmission means. The receiving unit 14 can also be implemented in a form in which the transmitting unit 13 and the portable receiving terminal 142 are directly communicated without using the relay device 141.

  In the present embodiment, together with the fact that an abnormality has occurred in the operating state of the negative pressure treatment device 1, warning information specifically specified up to the abnormality content can be received simultaneously by the receiving unit 14. Therefore, it is possible to more quickly take an optimum response to an abnormality that has occurred in the operating state of the negative pressure treatment device 1, and to minimize the adverse effects on the treatment of the wound portion W that accompany the occurrence of the abnormality. This is advantageous.

  Next, an embodiment of the abnormality warning method according to the present invention will be described together with the operation of the abnormality warning system 10 of the present embodiment.

  As shown in FIG. 3, the abnormality warning method of the present embodiment is a method for warning an abnormality related to the operating state of the negative pressure treatment apparatus 1. Detection step S <b> 11 for detecting the abnormality and specification step S <b> 12 for specifying the abnormality content The transmission step S13 for transmitting warning information corresponding to the abnormality content and the reception step S14 for receiving the warning information are included.

  The negative pressure treatment device 1 operates the suction means 2 with a predetermined operation setting based on a prescription from a doctor, and decompresses the inside of the container 3 by sucking the air in the container 3 through the suction flow path 2a. The body fluid exuded from the wound part W is sucked through the suction channel 2b drawn from the inside covered with (S0). The drained liquid sucked and discharged from the inside of the covering sheet S in this manner is dropped from the opening end of the suction flow path 2 b and is stored inside the container 3. When the container 3 is full of drainage, the container 3 is replaced with a new one, or the drainage is discharged from the container 3 and the drainage already contained is discarded.

  Here, if any abnormality occurs in the operating state of the negative pressure treatment device 1, the following adverse effects may be induced. For example, when the container 3 is filled with the drainage, there is a high possibility that the drainage will flow into the apparatus. This causes an abnormality in which the continuous operation of the suction means 2 becomes impossible. If the drainage liquid flows into the device, it may cause damage to the components such as the suction means 2, but it may not be possible to repair due to hygiene problems such as infection, and the entire device must be disposed of. It may disappear.

  In addition, when an abnormality occurs in the inner pressure state covered with the covering sheet S (such as the occurrence of an air leak or an excessive negative pressure state), the treatment that should be performed is not normally performed. If such a situation continues for a long time, the desired therapeutic effect cannot be obtained, and the risk of developing an infectious disease or the like increases, which may worsen the symptoms of the wound.

  Since the negative pressure treatment device 1 is a medical device used for the treatment of the wound portion W that is continuously performed for a long period of time, the negative pressure treatment device 1 is effective for the wound portion W when the treatment is forced to be interrupted for a long time. Can not be treated properly. Therefore, in the present embodiment, an abnormality relating to the operating state of the negative pressure treatment device 1 is warned to a doctor, a nurse, or the like as follows.

  First, as a detection step S11, an abnormality relating to the operating state of the negative pressure treatment device 1 is detected. The abnormality detected here is, for example, an abnormality in which the inside of the container 3 is filled with drainage and the suction unit 2 cannot be continuously operated, the inside covered with the covering sheet S, or the suction flow Examples include abnormalities in which air leaks and excessive negative pressure occur in the paths 2a and 2b. These abnormalities can be detected by the full detection sensor 111 and the pressure sensors 112 and 113 described above. When no abnormality is detected, the operating state of the negative pressure treatment device 1 is maintained.

  Next, when any abnormality is detected in the detection step S11, as the specific step S12, the abnormality content is specified based on the information related to the abnormality detected in the detection step S11. In the present embodiment, information corresponding to the detection signals from the sensors 111 to 113 is stored in the storage unit 15 in advance, and the detection signal is transmitted from the detection signal transmitted from any sensor to the control unit 12. By performing information processing for acquiring the corresponding information, the content of the abnormality that has occurred in the operating state of the negative pressure treatment device 1 is specified.

  For example, the information corresponding to the detection signal from the full detection sensor 111 corresponds to an abnormality in which the continuous operation of the suction unit 2 is impossible. The information corresponding to the detection signals from the pressure sensors 112 and 113 allows the control unit 12 to distinguish between the case where the measured value exceeds the upper limit value of the threshold range corresponding to the operation setting and the case where the measured value falls below the lower limit value. In addition, it is only necessary to deal with the occurrence of air leak and excessive negative pressure. By adopting such a specifying method, it is possible to easily and reliably specify the content of an abnormality that has occurred in the operating state of the negative pressure treatment device 1 without requiring complicated information processing.

  Subsequently, as sending step S13, warning information corresponding to the abnormality content specified in specifying step S12 is sent to the receiving unit. In the present embodiment, information acquired from the storage unit 15 by information processing performed by the control unit 12 in order to identify the abnormality content is used as warning information as it is. In addition, the transmission unit 13 causes the warning information to be transmitted based on the processing signal transmitted from the control unit 12 using the detection signal from the detection unit 11 as a trigger. Accordingly, there is an advantage that accurate warning information can be automatically transmitted from the transmitting unit 13 to the receiving unit 14 without the patient himself / herself taking an action for notifying the occurrence of the abnormality.

  Next, as reception step S14, the warning information transmitted in transmission step S13 is received. In the present embodiment, when the warning information transmitted from the transmission unit 13 is received by the reception unit 14, the warning information is specifically combined with the fact that an abnormality has occurred in the operating state of the negative pressure treatment device 1. Information about the identified abnormal content is also included. Therefore, it is possible to more quickly take an optimum response to an abnormality that has occurred in the operating state of the negative pressure treatment device 1, and to minimize the adverse effects on the treatment of the wound portion W that accompany the occurrence of the abnormality. This is advantageous.

  As described above, according to the abnormality warning system 10 and the abnormality warning method of the present embodiment, even if an abnormality occurs in the operating state of the negative pressure therapy apparatus 1, the occurrence of the abnormality is notified separately from the existing warning means 4. Warning information is sent automatically. Therefore, even if the patient does not take any action for notifying the occurrence of the abnormality, the doctor or nurse can be surely notified of the occurrence of the abnormality. Therefore, it is possible to avoid a situation in which a considerable amount of time has passed without the patient himself / herself noticing the occurrence of the abnormality and the response to the abnormality is greatly delayed.

  Moreover, in the present embodiment, the warning information that is specified up to the content of the abnormality that has occurred in the operating state of the negative pressure treatment device 1 is transmitted. As a result, since the doctor or nurse can quickly and optimally cope with the abnormality that has occurred in the operating state of the negative pressure treatment device 1, the adverse effect on the treatment of the wound part W accompanying the occurrence of the abnormality is minimized. While suppressing, the operating state of the negative pressure treatment device 1 can be recovered early to a normal state.

  In addition, by using the fullness detection sensor 111 as the detection unit 11, it is possible to detect an abnormality in which the continuous operation of the suction unit 2 is impossible, and a situation where the drainage fluid flows into the negative pressure treatment apparatus 1. Can be prevented. Thereby, failure etc. of various components, such as suction means 2, can be prevented, and the operating efficiency of negative pressure treatment device 1 can be maintained above a fixed level. In addition, since it is possible to avoid a situation where the entire apparatus must be disposed of, it is possible to contribute to the reduction of costs for reinvestment and the like.

  Furthermore, by using the pressure sensors 112 and 113 as the detection unit 11, an abnormality relating to the inner pressure state covered with the covering sheet S is detected, and the wound part W is treated differently from the prescription from the doctor. The time for entering the state can be greatly reduced. Thereby, it becomes possible to raise the effective operation rate of the said apparatus in the treatment of the wound part W using the negative pressure treatment apparatus 1 more.

  Although the abnormality warning system 10 and the abnormality warning method according to the present embodiment have been described above, the present invention can be implemented in other forms.

  For example, in the above-described abnormality warning system 10, as shown in FIG. 4, information accompanying the above-described warning information, such as a handling manual corresponding to various abnormality contents specified by the control unit 12, is previously stored as “specific information”. You may make it memorize | store in the memory | storage part 15, and you may comprise the transmission part 13 so that the said specific information may be transmitted with warning information (S23).

  Specific examples of the specific information include a “replacement procedure of the container 3” for an abnormality detected by the fullness detection sensor 111, an “operation procedure of the negative pressure treatment device 1” and an “abnormality” for the abnormality detected by the pressure sensors 112 and 113. For example, “confirmation procedure of location”. In addition, information on the patient such as “name of doctor in charge” and “treatment history (electronic medical record)” may be included. Such specific information can be received by the receiving unit 14 together with the warning information (S24).

  In general, when a response is required in the absence of any information on the details of the abnormality that occurred, experienced doctors and inexperienced nurses, for example, identify the abnormality content and optimize it according to the abnormality. There is a high possibility that a large difference will occur in the speed of judgment such as selection of a correct coping method. However, according to such an embodiment, it is possible to omit the response to make these judgments that are likely to cause empirical and artificial differences, and the speed and accuracy of response to abnormalities by doctors and nurses, etc. Can be further enhanced, and at the same time, the difference in the quality of the correspondence can be greatly reduced.

  Further, in the above-described abnormality warning system 10, as shown in FIG. 4, the transmission unit 13 is configured to transmit information indicating that a response to warning information has been made, and the corresponding information is not received by the reception unit 14. In such a case, the warning information (and the specific information) may be automatically retransmitted periodically at regular intervals (S35, S36).

  Specifically, as shown in FIG. 2, an authentication password or the like is input at the input unit 16 provided in the negative pressure treatment apparatus 1, and it is confirmed whether or not the transmission of the corresponding information is completed at the display unit 17. A form is mentioned. The input unit 16 and the display unit 17 may employ a touch panel having both functions. Further, an authentication unit (not shown) that performs magnetic authentication, biometric authentication, and the like may be provided, and the corresponding information may be automatically transmitted from the transmission unit 13 using an authentication signal as a trigger. Alternatively, the control unit 12 determines whether or not the normal operation state has been restored from the detection signal of the full detection sensor 111, the measurement values of the pressure sensors 112 and 113, and the corresponding information is automatically transmitted. May be.

  According to this embodiment, it becomes possible for a doctor, a nurse, or the like to easily check the response status to the abnormality after the abnormality has occurred. As a result, it is possible to omit useless movements such as duplicate correspondence by doctors, nurses, etc., and at the same time, it is possible to reliably prevent the user from being left unattended without any response to the abnormality that has occurred.

  Furthermore, in the above-described abnormality warning system 10, the transmitter 13 may be configured to periodically transmit information indicating that the operating state of the negative pressure treatment device 1 is normal. For example, during the continuous operation of the negative pressure treatment device 1, the control unit 12 periodically confirms whether or not an abnormality has occurred, and when no abnormality is observed at the time of performing this confirmation process, the receiving unit 13 receives the receiving unit 13. It is possible to adopt a form in which information to that effect is transmitted to 14. In addition, when the fact of abnormality occurrence is recognized when the confirmation process is performed by the control unit 12, it is not necessary to transmit any other information. In this case, warning information (and specific information) has already been transmitted.

  According to this embodiment, even in a situation where a doctor, a nurse, or the like is away from the patient, the doctor, a nurse, etc. always confirms the operating state of the negative pressure treatment device 1 indirectly. be able to. Thereby, it becomes possible to remotely observe the patient who is treating the wound portion W using the negative pressure treatment device 1.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Moreover, you may implement with the form which substituted any invention specific matter to the other technique within the range which the same effect | action or effect produces.

  For example, as shown in FIG. 2, the negative pressure treatment device 1 uses the fluid (cleaning liquid) supplied from the cleaning liquid bag through the supply flow path to the wound part W through the delivery flow path depending on the symptoms of the wound W of the patient. You may use what was provided with the delivery means 5 sent out to the inner side of the coating sheet S to cover. The delivery means 5 can employ a metering pump such as a tube pump, a piston pump, a diaphragm pump, or a vane pump.

  Further, the negative pressure treatment device 1 may be a built-in type or a portable type using a battery or the like as a power source. When the negative pressure treatment device 1 is a portable type, the negative pressure treatment device 1 may automatically stop with the loss of power. For this reason, as shown in FIG. 2, it is more preferable that the detection unit 11 includes a battery remaining amount measuring unit 114. As a result, it is possible to prevent the occurrence of an abnormality caused by the stoppage of the apparatus.
