Description

Technical Field

[0001] The present invention relates to a management system for medical devices and an impact detection device for medical devices. More specifically, the present invention relates to an impact detection device that detects an impact applied to a medical device, a management device that acquires impact information from the impact detection device and manages the impact information for a medical institution, and an impact detection device for medical devices that includes two sensors and a power supply unit.

Background Art

[0002] Medical devices such as syringe pumps and infusion pumps are usually stored in a place where maintenance management is performed, such as a so-called ME center, and when needed, they are taken out from there and used at a medical site such as a hospital ward.

[0003] Therefore, when taking out or attaching, a nurse or the like may accidentally drop the medical device or hit it against a wall, thereby applying an unexpected impact to the medical device. Such an impact on the medical device may lead to a malfunction or an incorrect operation of the medical device, so it is necessary to prevent it as much as possible. If such an impact is applied, it is necessary to accurately grasp the fact and perform repair and inspection. That is, risk management of medical devices due to impact is important.

[0004] As a system for performing risk management of impacts applied to such medical devices, Patent Document 1 discloses a medical device operation management system by constant remote monitoring. The management system of this Document 1 is a system in which a remote monitoring active type RFID tag (hereinafter appropriately referred to as a detection device) equipped with an acceleration sensor for detecting a physical impact is attached to a medical device, and constant remote monitoring is performed.

[0005] And, since it is always remote monitoring, if a medical device drops or the like occurs at the site, it can be immediately known, so risk management of medical devices at the site can be carried out by contacting the nurses at the site or the like. Also, since the record of the occurrence of a drop or the like remains, risk management of medical devices during maintenance management can also be carried out. That is, risk management of medical devices is realized in two scenarios: the medical site and maintenance management.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Since Patent Document 1 is a system that performs constant remote monitoring, there is a problem that the introduction cost and operation cost are large.

[0009] For example, in terms of the introduction cost, the system of Patent Document 1 requires, in addition to the active type RFID tag for remote monitoring attached to the medical device, a small relay wireless line for location management. Also, for operation via a wireless LAN network, it is natural that a wireless LAN network needs to be introduced in the hospital. It is natural that small-scale hospitals bear the introduction cost for such environmental preparation, but even in large-scale hospitals where the number of medical devices reaches several thousand, the introduction cost also increases because the number of devices for system construction increases.

[0010] In terms of operation costs, since it is a system for constant monitoring, personnel such as clinical engineering technicians who conduct monitoring are constantly required. However, in reality, since the probability of troubles occurring in medical devices is low, constantly having someone monitor at a low occurrence probability leads to an increase in human costs.

[0011] In addition, a system like that of Patent Document 1 creates a mental burden for nurses and the like who install and use medical devices at the site, as they are constantly being monitored. Therefore, for nurses and the like who already have a heavy burden in their original work, it is not preferable as it increases the extra burden. Also, depending on the medical device, for example, when the medical device is attached to an IV pole, the patient may move on their own. In such a case of use, if the patient knows that the medical device is constantly being remotely monitored, it also becomes a mental burden for the patient.

[0012] In addition, in the system of Patent Document 1, since information is regularly transmitted from the detection device attached to the medical device, the influence on the medical device and surrounding devices by electromagnetic waves is also conceivable.

[0013] In addition, as described in paragraph number

[0069] of Patent Document 1, the mounting position of the detection device is limited to a position where power reception of the commercial power supply can be detected. However, the actual shapes of medical devices are various. For example, even in a case where it is not desired to mount such a detection device near the operation part of the medical device, there are medical devices where the position where power reception of the commercial power supply can be detected and the operation part of the medical device are very close. Therefore, it is preferable that the mounting position of the detection device is not limited.

[0014] In addition, since the usage period of medical devices at the site also varies, it is preferable to minimize the power consumption of the detection device as much as possible so that it can still operate even when used for a long time. However, in a system like that of Patent Document 1, since regular communication is required, the power consumption of the detection device increases, resulting in problems such as difficulty in long-term use or an increase in the size of the detection device due to an increase in the size of the power supply.

[0015] In addition, depending on the scale of the hospital, it is conceivable that there may be no department for maintenance management such as an ME center within the hospital. Under such circumstances, for example, outsourcing the maintenance management of medical devices or leasing medical devices can be considered. However, in the system such as in Document 1, such usage is not assumed and it cannot be actually operated. As described above, since there are many problems such as an increase in costs in the system of Patent Document 1, its actual introduction is difficult.

[0016] On the other hand, an impact detection chip for medical devices such as in Non-Patent Document 1 does not have the difficulty of introduction as in Patent Document 1. However, if a predetermined impact is detected, replacement is required each time. Also, it can be used for risk management of medical devices at the site such as use in a hospital ward, but it is difficult to use for risk management of medical devices during maintenance management. Specifically, the chip of Non-Patent Document 1 changes when an impact above a certain level is applied, or does not change if an impact above a certain level is not applied. However, problems may occur in the use of the device when impacts below a certain level are applied multiple times. With the impact detection chip for medical devices in Non-Patent Document 1, such detailed past history cannot be known. An object of the present invention is to provide a management system for medical devices with reduced costs without constantly performing remote monitoring.

[0017] Furthermore, an object of the present invention is to provide a management system for medical devices that can perform risk management of medical devices at the site and risk management of medical devices during maintenance management. Furthermore, an object of the present invention is to provide an impact detection device for medical devices that is optimal as an impact detection device used in a management system for medical devices.

Means for Solving the Problems

[0018] In order to solve the above problems, a management system for medical devices according to one aspect of the present invention includes an impact detection device that is detachably attached to a medical device and detects an impact applied to the medical device, and a management device that acquires impact information from the impact detection device and manages the impact information to the medical institution. The impact detection device includes a sensor unit that measures an impact, a storage unit that stores measurement values, a transmission unit that transmits the measurement information of the storage unit to the management device by an operation of starting transmission by an operator, and a power supply unit. The management device includes a reception unit that receives the measurement information from the transmission unit of the impact detection device, and a management unit that manages the medical device based on the received measurement information.

[0019] In the impact detection device, since the impact value is stored, information is sent to the management device by a transmission start operation, and the medical device is managed based on the measurement information, unlike the always-remote monitoring system of Patent Document 1, a wireless device other than the impact detection device and a wireless LAN network are not required, so the introduction cost can be suppressed. Also, since it is not necessary to always monitor, the labor cost can be suppressed. Also, since it is not always-remote monitoring, the mental burden on nurses and patients at the site is small. Also, when measuring with the impact detection device at the site, it is not necessary to perform regular communication, so there is no risk of affecting medical devices and peripheral devices by electromagnetic waves. Also, since this management system for medical devices is based on the measurement of impact, information on the electric field strength as in Document 1 is not required, and the mounting position of the impact detection device is not limited. Also, since this management system for medical devices does not always perform monitoring, in the case of a small-scale hospital where there is no department for direct maintenance management within the hospital or when leasing medical devices, after the medical devices are recovered by an outsourcing destination for maintenance management or a leasing company, it can be used for the maintenance management of the medical devices.

[0020] Further, in the management system for medical devices of the present invention, it is preferable that the impact detection device further includes a determination unit that determines whether or not an impact equal to or greater than a certain level has been measured, and a notification unit that performs notification when it is determined by the determination unit that an impact equal to or greater than a certain level has been measured.

[0021] This enables the impact detection device to also determine that a dangerous impact has been applied to the medical device during use. As a result, it becomes possible to manage risks not only for medical devices during maintenance but also for medical devices in the medical field. In particular, since the medical device management system of the present invention is not constantly monitored by clinical engineering technicians or the like, the mental burden on nurses, patients, etc. is also small.

[0022] Further, in order to solve the above problems, an impact detection device for a medical device according to one aspect of the present invention is an impact measurement device for a medical device that measures an impact applied to the medical device, and includes a first sensor that constantly measures the acceleration of the medical device, a second sensor that measures the impact when a predetermined acceleration is measured by the first sensor, a determination unit that determines whether or not an impact equal to or greater than a certain level has been measured by the second sensor, and a notification unit that performs notification when it is determined by the determination unit that an impact equal to or greater than a certain level has been measured, and a power supply unit.

[0023] Normally, the first sensor with low power consumption measures a small impact such as the start of a fall that occurs in the medical device. When the first sensor measures it, the second sensor is activated to measure the large impact actually applied to the medical device, thereby suppressing the power consumption of the entire device. Therefore, the power supply unit can also be small, resulting in a smaller device.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, embodiments for carrying out the present invention will be described with reference to the embodiments and the drawings. However, the following embodiments are not intended to limit the present invention to those described herein, and the present invention can be equally applied to various modifications without departing from the technical idea shown in the claims. In each drawing used for the description in this specification, in order to make each member recognizable on the drawing, scales are made different for each member, and they are not necessarily shown in proportion to the actual dimensions.

[0026] [Embodiment] The configuration of the main part of the medical device management system 100 according to the embodiment of the present invention will be described. FIG. 1A is a diagram showing an image of the medical device management system 100. The medical device management system 100 includes an impact detection device 1 that is detachably attached to a medical device MD with double-sided tape and detects an impact applied to the medical device MD, and a management device 3 that is installed in a ME (Medical Engineering) center, acquires impact information from the impact detection device 1, and manages the impact information for a medical institution.

[0027] The medical device MD to which the impact detection device 1 is attached is an infusion pump, a syringe pump, or the like, and these are used in a medical site such as a hospital ward or a hospital bed. Also, at the ME center that performs maintenance management of the medical device MD, the medical device MD that has been used at the medical site is collected. Then, a clinical engineering technician takes in the impact information from the impact detection device 1 into the management device 3 and checks this impact information. When it is determined that maintenance such as inspection or repair of the medical device MD is necessary after checking the impact information, the maintenance is performed. The medical device MD for which no problem is found regarding use after checking the impact information or the medical device MD for which maintenance has been completed is stored until it is used and taken out to the medical site when needed.

[0028] Note that as the management device 3 in the present embodiment, a notebook computer is used, but a desktop computer or a dedicated device may also be used. Also, the installation location of the management device 3 is not limited to the ME center where a national qualification clinical engineering technician is required, and general medical staff or employees may use the management device 3 at a desired location. Also, it is not limited to within a hospital, and the ME center in FIG. 1A may be an outsourcer for maintenance or a rental company for medical devices MD. Also, the impact detection device 1 is attached to the medical device MD with double-sided tape, but it may be detachably attached via a hook-and-loop fastener or an attachment for attachment.

[0029] [Configuration of Medical Device Management System] The configuration of each main part of the medical device management system 1 will be described with reference to FIGS. 1B, 1C, 2, and 3. FIG. 1B is a perspective view of the appearance of the impact detection device 1, FIG. 1C is a perspective view of the printed circuit board 11 of the impact detection device 1, FIG. 1D is a perspective view of the bottom surface of FIG. 1C, and FIG. 2 is a block diagram of the impact detection device 1. FIG. 3 is a block diagram of the management device 3.

[0030] The impact detection device 1 includes a sensor unit that measures impact, a storage unit that stores measurement values, a transmission unit that transmits the measurement information of the storage unit to the management device 3 by an operation of the operator to start transmission, and a power supply unit. More specifically, as shown in FIGS. 1C and 1D, on the printed circuit board 11 that constitutes the impact detection device 1, there are mounted an LSI having a control unit 12 and a communication unit 13 capable of transmission and reception, a storage unit 14 composed of an EEPROM or the like, a first sensor 15, a second sensor 16, a red (R) LED 171, a switch 18, and a detachable battery 19.

[0031] Here, the first sensor 15 is a three-axis acceleration sensor used to detect that the medical device MD has fallen freely or the like. Specifically, LIS2DW12 manufactured by STMicroelectronics is used. And the first sensor 15 has a narrow measurement range of ±16 g, but is a smaller and more power-saving acceleration sensor than the second sensor 16.

[0032] Also, the second sensor 16 is an acceleration sensor used to measure the impact applied to the medical device MD. Specifically, ADXL375 manufactured by Analog Devices is used. The second sensor 16 has a wide measurement range of ±200 g and is a three-axis acceleration sensor. Also, the battery 19 constitutes the power supply unit, and specifically, a CR2032 button battery is used.

[0033] As shown in FIG. 1B, the printed circuit board 11 is housed in a case 20 with packing (not shown) and a bottom cover 21. The light emitted from the LED 171 is guided and diffused by a transparent warning light 172 and visually recognized by the user.

[0034] An operation button 22 with one end screwed with a screw 221 is attached to the case 20. When the other end of the button 22 is pressed by the user, the switch 18 turns ON, and when the biasing force of the pressing is removed, the switch 18 returns to OFF. Also, the battery 19 can be replaced by a battery cover 23 that can be detached by rotating it from the case 22.

[0035] As shown in the block diagram of FIG. 2, the storage unit 14 of the impact detection device 1 stores a program 141 such as an operating system and an application program, and data 142 such as a registered name, a weight group, and impact information. The control unit 12, which is a CPU, controls each unit based on the program 141 (see FIG. 6). The communication unit 13 equipped with the antenna 131 transmits and receives data to and from the management device 3. The first sensor 15 sends the measured acceleration information to the control unit 12. The second sensor 16 sends the measured acceleration information to the control unit 12. The switch 18 sends ON / OFF information to the control unit 12. The notification unit 17 composed of the LED 171 and the notification lamp 172 emits red light (R) based on the operation of the control unit 12. The battery 19 is a power supply unit for each unit and supplies driving power to each unit.

[0036] The management device 3 includes a receiving unit that receives measurement information from the communication unit 13 of the impact detection device 1, and a management unit that manages the medical device MD based on the received measurement information. More specifically, as shown in the block diagram of FIG. 3, the storage unit 31 of the management device 3 stores a program 311 such as an operating system and an application program, and data 312 such as a registered name, a weight group, and impact information (see FIG. 5A). The management unit 32, which is a CPU, controls each unit based on the program 311 (see FIG. 7). The communication unit 33 capable of transmission and reception equipped with the antenna 331 transmits and receives data to and from the impact detection device 1. The input unit 34 consists of a keyboard or the like and transmits the input data to the management unit 32. The display unit 35 composed of a liquid crystal display device performs display based on the management unit 32. The power supply unit 36 consists of a rechargeable battery or a commercial power supply and supplies driving power to each unit.

[0037] [Method of Detecting and Determining Impact] Next, with reference to FIG. 4, the detection and determination of impact in the impact detection device 1 of the present embodiment will be described. FIG. 4 is a waveform of the first sensor 15 and the second sensor 16 showing the measurement method in the impact detection device 1.

[0039] When the natural fall of the medical device MD to which the impact detection device 1 is attached starts, the acceleration measured by the first sensor 15 begins to decrease, and the measured value becomes zero. The control unit 12 detects the start of the natural fall based on this change amount (T0 in FIG. 4). Then, the control unit 12 starts measuring the acceleration with the second sensor 16 (T0 in FIG. 4). When the medical device MD falls to the floor, the impact value (acceleration) starts to be measured by the second sensor 16 (T1 in FIG. 4). When the impact subsides, that is, when the acceleration below the threshold continues for a predetermined time (T2 in FIG. 4), the control unit 12 stops measuring the acceleration with the second sensor 16. Then, the control unit 12 stores the maximum value of the measured impact in the storage unit 14 as impact information.

[0040] In this way, the impact detection device 1 is configured to intermittently detect the acceleration with the second sensor 16 only when an impact is predicted by using the first sensor 15 with ultra-low power consumption that constantly measures the acceleration. That is, the second sensor 16 enters the standby mode when it is not detecting the acceleration (when outside the measurement period in FIG. 4B) and hardly consumes power. Therefore, the impact detection device 1 can lighten the battery 19 or extend the life of the battery 19, and is very suitable as an impact detection device for medical devices because it is small, lightweight, and can be used for a long time.

[0041] Note that the first sensor 15 is a three-axis acceleration sensor, and the normal acceleration is zero except in the direction of free fall. However, when the medical device MD collides with a wall on its side without free fall, the lateral acceleration will increase rapidly. Therefore, the impact detection device 1 can also measure impacts without free fall by starting the measurement with the second sensor 16 based on the change amount from zero to a predetermined value in the first sensor 15.

[0042] Also, the first sensor 15 of the impact detection device 1 is not necessarily limited to the one exemplified in this embodiment, and for example, a vibration sensor can also be used instead of the acceleration sensor.

[0043] [Operation of Medical Device Management System] Using FIGS. 5, 6, and 7, the main operations of the management system for medical devices will be described. FIG. 5 is a flowchart showing the operation of the control unit 12 of the impact detection device 1. FIG. 6 is a flowchart showing the operation of the management unit 32 of the management device 3. FIG. 7A is a display screen of the determination result of the management device, and FIG. 7B is a table showing an example of the display of stored data.

[0044] First, although not shown, information regarding the attached medical device MD is acquired by the impact detection device 1 through communication with the management device 3 and stored in the storage unit 14. Communication with the management device 3 is performed by an operation to start transmission. Specifically, it is performed by pressing the button 22 of the impact detection device 1. Also, as information regarding the medical device MD, there are a registration name for identifying the medical device MD, a weight group of the medical device MD described later, information on the impact value at which use should be stopped corresponding to the weight group, and the like.

[0045] Next, the impact detection operation of the impact detection device 1 will be described. First, when the natural fall of the medical device MD is detected by the measurement of the first sensor 15 (Y in S1), the second sensor 16 starts measuring the acceleration and measures until the fall ends (S2). Then, the maximum impact value (acceleration) during the measurement period is stored in the storage unit 14 as impact information (S3). Note that this impact information may include other information such as the information on the measurement period (ms), the information on the direction of the detection axis, and the information on the date and time, in addition to the maximum impact value.

[0046] Then, based on the next measured impact value, it is determined whether notification by the notification unit 17 is necessary (S4). Specifically, the determination is made based on whether the measured impact value is greater than the impact value at which use should be stopped stored in the storage unit 14. And if the result of the determination is greater than the impact value at which use should be stopped (Y in S4), the red LED 171 of the notification unit 17 is lit (S5).

[0047] Thus, the lighting of the notification unit 17 in the impact detection device 1 is a notification for temporarily suspending the use of the medical device MD by a nurse or the like. Therefore, the medical device management system 100 can also perform risk management of medical devices at the medical site using the impact detection device 1. Note that the notification method in the impact detection device 1 is not limited to light, and for example, notification by sound may also be used.

[0048] Next, the management operation of the impact information of the management device 3 will be described. The management device 3 displays a request screen for pressing the button of the impact detection device 1 as shown in FIG. 7A on the display unit 35 (S11). When the button 22 of the impact detection device 1, which is an operation to start transmission, is pressed after confirming the display on the display unit 35, communication is started. Then, the registered name and impact information of the impact detection device 1 are transmitted, and the management device 3 receives this information (S12). Then, the received impact information and the like are stored in the storage unit 31 (S13). Then, when the determination start (not shown) on the display unit 35 is selected by a clinical engineering technician or the like (Y in S14), a determination process is performed.

[0049] This determination process will be described. There are various medical devices MD, and the weights of the devices are different. And even for the same impact value, the damage to the medical device MD varies depending on the weight. In the present embodiment, the management device 3 roughly classifies the weights of the medical devices MD into three groups A, B, and C as shown in FIG. 7A. For example, the weight of the medical device MD around 1 kg is set as group A, around 2 kg as group B, and around 3 kg as group C.

[0050] And in the management device 3, based on the pre-verified results, for Group A, the judgment criteria are set as follows: when the impact value is 80 (g) or less, the judgment result G (green) indicates no problem for use; when it is between 80 (g) and 110 (g), the judgment result Y (yellow) indicates that inspection is necessary; when it is 110 (g) or more, the judgment result R (red) indicates that it cannot be used. Also, for Group B, the judgment criteria are set as: when it is 70 (g) or less, the judgment result is G; when it is between 70 (g) and 100 (g), the judgment result is Y; when it is 100 (g) or more, the judgment result is R. For Group C, the judgment criteria are set as: when it is 60 (g) or less, the judgment result is G; when it is between 60 (g) and 90 (g), the judgment result is Y; when it is 90 (g) or more, the judgment result is R. In the management device 3, judgment processing based on such judgment criteria is performed.

[0051] And the judgment result of the judgment processing is displayed on the display unit 35 (S15). In the present embodiment, as shown in FIG. 7A, for the medical device MD (registered name: SHOCK-01) belonging to Group B, the judgment result R indicating that it cannot be used is lit (the filled part). Then, when the saved data display on the screen is selected (Y in S16), the data shown in FIG. 7B is displayed (S17).

[0052] By checking the display in FIG. 7B, it can be seen that for the medical device MD (registered name: SHOCK-01) in Group B, during use, an impact that requires inspection (70 - 100 g) occurred once, and an impact that stops use (100 g or more) occurred once.

[0053] In this way, since the rank of the impact can be notified to clinical engineering technicians and the like via the management device 3, risk management of medical devices can be easily performed in the scene of maintenance management.

[0054] Note that the display example in Fig. 7B is merely a display example for explanation purposes. In this embodiment, the impact detection device 1 is configured to be able to store up to 5 impacts. Fig. 7B shows that 4 impacts have been measured in the impact detection device 1. Also, the number of impact measurements does not necessarily have to be limited to 5, and more measurements are also possible. However, in the normal use of the medical device MD, it is considered sufficient if about 5 impacts can be measured.

[0055] In addition, the impact detection device 1 is provided with a notification unit 17, which performs notification when a large impact is applied to the medical device MD at the medical site. However, the criteria for notification by the notification unit 17 and the determination criteria (G, Y, R) for maintenance management performed by the management device 3 may be different criteria.

[0056] Also, since the impact detection device 1 transmits impact information to the management device 3 only when the button 22 is pressed, it is not always remotely monitored, reducing the system introduction cost and having less impact on medical devices by electromagnetic waves. Note that the communication connection between the impact detection device 1 and the management device 3 was antenna communication, but the present invention is not limited to this, and it may be a connector such as a wired cable or USB.

[0057] In addition, in the medical device management system 100, the impact detection device 1 uses a communication unit 13 capable of transmission and reception, and the management device 3 uses a communication unit 33 capable of transmission and reception. However, the impact detection device 1 may be configured to use only a transmission unit for transmission, and the management device 3 may be configured to use only a reception unit for reception.

[0058] Also, although not shown, in the management system 100 for medical devices of the present invention, the registered name and weight group of the impact detection device 1 in the storage unit 14 can be changed. For example, the registered name can be deleted and changed on the screen displayed by clicking the "Initial Registration" tab in FIG. 7A. Further, the management system 100 for medical devices of the present invention erases the impact recording data simultaneously when reading the impact recording data. By these functions, it becomes possible to reuse the impact detection device 1 for medical devices MD that have no problems after the operation inspection of the medical device MD, or to divert the impact detection device 1 to other medical devices MD.

[0059] Also, in the present embodiment, the impact detection device 1 was configured together with the management system 100 for medical devices and the management device 3, but the impact detection device 1 can also be used as a single impact detection device for medical devices. Even when used as a single impact detection device for medical devices, it can be small and used for a long period of time, and it is possible to perform risk management of medical devices at the medical site.
