Description

[Technical field]

[0001] The present disclosure relates to a blood leak detection device. [Background technology]

[0002] In extracorporeal circulation therapy such as hemodialysis, blood leakage due to the needle coming loose on the blood return side or the circuit being disconnected is a serious accident. If treatment is continued without noticing the needle coming loose, a large amount of bleeding will occur in a short period of time. For this reason, it is very important to detect blood leakage early when it occurs.

[0003] In many dialysis facilities, dozens of beds are placed in large dialysis rooms, and one staff member is responsible for caring for about 5 to 10 patients. This makes it impossible to continuously visually monitor each patient to see if there is any blood leakage.

[0004] For this reason, the use of blood leakage detection devices that detect blood leakage has been proposed. For example, there is a device in which a detection unit that electrically detects blood leakage is placed close to the patient, and a drive unit for the detection unit and a main body of the detection device that has an alarm unit that issues an alarm when blood leakage is detected are placed a short distance away from the patient (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-196293 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, even when such a blood leakage detection device is used, it is difficult to quickly determine where the alarm is sounding in a large dialysis room.

[0007] Many blood leakage detection devices have a function to sound an alarm by emitting light from a light-emitting unit. However, since the light-emitting unit is provided on the panel surface on which the operation buttons of the blood leakage detection device are provided so that it faces the operator, the light-emitting unit is hidden behind the housing unless the operator happens to be in front of the panel surface. Therefore, in a large dialysis room, the position cannot be identified unless the operator gets close to the device by sound.

[0008] By providing the light-emitting unit on the top surface of the housing, the light-emitting unit can be made visible from behind or beside the blood leak detection device. However, the blood leak detection device is often placed above the eye level of the dialysis device so as to avoid being in the blind spot of the dialysis device or bed as much as possible. In this case, if an operator stands in the narrow gap between the bed and the dialysis device and looks up at the blood leak detection device, the light-emitting unit may be in the blind spot hidden by the housing of the blood leak detection device, and the operator may have to move away from the patient again to check.

[0009] An object of the present disclosure is to realize a blood leakage detection device in which the area in which the light alarm is hidden is narrow and the device's location can be quickly confirmed and operated. [Means for solving the problem]

[0010] A first aspect of the blood leakage detection device of the present disclosure comprises an electronic device having an alarm unit to which a detection unit for detecting blood leakage is connected and which sounds an alarm when blood leakage is detected, and a housing in which the electronic device is housed, the alarm unit having a light-emitting unit that emits light, the housing being capable of being hung with the top surface facing up by a hanging section, the body having operation buttons for a user to operate the electronic device, and the light-emitting unit being formed continuously or intermittently so as to circle the body below the top surface.

[0011] In the first aspect of the blood leakage detection device, the light emitting unit is formed continuously or intermittently around the body below the top surface, so that the light emission is easily visible from any direction even at a distance. Also, the light emitting unit is not hidden by the housing unless it is directly below, so it can be easily confirmed even when looking up from close up. Therefore, an operator who monitors and deals with blood leakage in patients can easily identify the patient with blood leakage and can deal with it quickly.

[0012] A second aspect of the blood leakage detection device comprises an electronic device to which a detection unit for detecting blood leakage is connected and which has an alarm unit that sounds an alarm when blood leakage is detected, and a housing in which the electronic device is housed, the alarm unit having a light-emitting unit that emits light, the housing being capable of being hung with the top surface facing up by a hanging part, and having operation buttons on the body part for a user to operate the electronic device, the light-emitting unit being formed continuously or intermittently so as to circle around the body part, and the hanging part being formed above the light-emitting unit.

[0013] In the second embodiment of the blood leakage detection device, the hanging part is formed above the light emitting part that is formed continuously or intermittently so as to go around the body part. Therefore, the light emission is easily visible from any direction even at a distance, and when approaching and looking up, the light emitting part is not hidden by the hanging part, so confirmation is easy. Therefore, an operator who monitors and deals with blood leakage of patients can easily identify the patient who is experiencing blood leakage and can deal with it quickly.

[0014] In the first and second aspects of the blood leakage detection device, the light emitting section has a light emitting element housed in a housing and a light emitting window section that allows light from the light emitting element to pass to the outside, and the light emitting window section can be formed continuously or intermittently around the body section. With this configuration, it is easy to emit light in the entire circumferential direction of the blood leakage detection device.

[0015] In the first and second aspects of the blood leakage detection device, the light emitting unit can be formed above the operation button. With this configuration, when the blood leakage detection device is positioned so that the operation button is at a height that makes it easy to operate, the light emitting window is located higher and is less likely to be hidden by the dialysis machine or bed.

[0016] In the first and second aspects of the blood leakage detection device, the hanging part can be a through hole that penetrates the housing. Compared to hanging using a belt or the like, the hanging part is less likely to deteriorate and accidents such as dropping can be less likely to occur. In addition, the hanging blood leakage detection device is less likely to swing or rotate and can be stabilized, improving operability.

[0017] A third aspect of the blood leakage detection device comprises an electronic device to which a detection unit for detecting blood leakage is connected and which has an alarm unit that sounds an alarm when blood leakage is detected, and a housing in which the electronic device is housed, the alarm unit having a light-emitting unit that emits light, the housing being capable of being hung with the top side facing up by a hanging section and having an operation button on the front side for a user to operate the electronic device, the light-emitting unit having a light-emitting front portion formed on the front side, a light-emitting rear portion formed on the rear side opposite the front side, a light-emitting right side portion formed on the right side, and a light-emitting left side portion formed on the left side, and each of the light-emitting front portion, light-emitting rear portion, light-emitting right side portion, and light-emitting left side portion has a light-emitting unit viewing point where a virtual line extending downward at an angle of 45° does not intersect with the housing below the light-emitting unit.

[0018] According to the third aspect of the blood leakage detection device, the light-emitting front part, the light-emitting rear part, the light-emitting right side part, and the light-emitting left side part each have a light-emitting part viewing point where a virtual line extending downward at an angle of 45° does not intersect with the housing below the light-emitting part, so that the light-emitting part is unlikely to be in the blind spot of the housing from any direction or when approaching the blood leakage detection device and looking up. This makes it easy to see the light emission from any direction, and it is also easy to check again after approaching the bed. This allows an operator who monitors and deals with blood leakage in patients to easily identify a patient with blood leakage and to deal with it quickly. Effect of the Invention

[0019] With the blood leak detection device disclosed herein, an operator who monitors and responds to blood leaks in a patient can easily see the light emitted from a distance or when approaching and looking up, thereby enabling the operator to respond quickly to blood leaks.

[0021] 1 to 4, a blood leakage detection device 100 of one embodiment is connected to a detection unit 200 that detects blood leakage and issues an alarm when blood leakage is detected. The blood leakage detection device 100 has a housing 101 that houses an electronic device that detects blood leakage and issues an alarm, and a hanging part 102 for hanging the housing 101.

[0022] In this embodiment, the electronic device has a substrate 150 on which an electronic circuit is formed, and an acoustic element that generates an alarm sound and a light-emitting element 151 that generates light when blood leakage is detected. The acoustic element and the light-emitting element 151 function as an alarm unit. In this embodiment, the light-emitting element 151 of the alarm unit is housed inside the housing 101, and the emitted light passes through a light-emitting window portion 131 provided in the housing 101 and is radiated to the outside of the housing 101. The light-emitting element 151 is not particularly limited, but is preferably a light-emitting diode (LED) from the viewpoints of miniaturization and reduced power consumption. The number of light-emitting elements 151 is not limited to one, and may be multiple.

[0023] In this embodiment, the housing 101 has a body portion 111 having a front surface 112, a rear surface 113, a right side surface 114 and a left side surface 115, and a top surface portion 117 and a bottom surface portion 118 that close both ends of the body portion 111, and the body portion 111 is approximately rectangular.

[0024] Housing 101 can be suspended by hanging part 102 with top surface 117 facing up. Hanging part 102 in this embodiment is formed of an inverted U-shaped member having two side pillars 121 protruding from top surface 117 and arch-shaped part 122 spanning between side pillars 121. Housing 101 can be suspended with top surface 117 facing up by inserting a rod-shaped member into through hole 102a formed by top surface 117 and the inverted U-shaped member, or by hanging arch-shaped part 122 on a hook.

[0025] Operation buttons 103 for a user to operate the electronic device are formed on a front surface 112 of the body portion 111. In addition to the operation buttons 103, a display 181 showing power on / off, a display 182 showing battery capacity, a display 183 showing device abnormalities, etc. are formed on the front surface 112, and the front surface 112 functions as an operation panel.

[0026] Below the top surface 117 of the body 111, the light emitting window 131 is continuously formed around the body 111. The light emitting window 131 is formed of a transparent material that transmits light, and transmits light emitted by the light emitting element 151 of the alarm unit housed inside the housing 101 to the outside of the housing, making it visible from the outside. Therefore, the light emitting window 131 combined with the light emitting element 151 does not emit light itself, but functions as the light emitting unit 130. The light emitting window 131 may be colorless or colored as long as it has a transparency that transmits light, but it is preferable to make it red or yellow from the viewpoint of attracting attention. The light emitting window 131 may be colorless and transparent and combined with the light emitting element 151 that emits red or yellow light.

[0027] In the blood leakage detection device of this embodiment, the light emitting window 131 of the light emitting unit 130 is formed continuously around the body 111, and the light emitting window 131 of the light emitting unit 130 has a light emitting front portion on the front surface 112 side, a light emitting rear portion on the rear surface 113 side, a light emitting right side portion on the right side surface 1144 side, and a light emitting left side portion on the left side surface 115 side. As a result, light is emitted not only on the front surface 112 side of the housing 101, but also on the rear surface 113, right side surface 114, and left side surface 115 sides. Therefore, the occurrence of an alarm due to blood leakage can be visually confirmed from any direction at a distance, making it possible to take a prompt response.

[0028] In the present embodiment, an example has been shown in which the light-emitting window 131 of the light-emitting unit 130 continuously circles the body unit 111, but a plurality of light-emitting windows 131 may be arranged discontinuously so as to circle the body unit 111. Note that, although an example has been shown in which the light-emitting window 131 is formed flush with the surface of the body unit 111, the light-emitting window 131 may also be configured to protrude from the surface of the body unit 111.

[0029] In this embodiment, an example has been shown in which the light emitting unit 130 is formed by a light emitting element 151 housed in the housing 101 and a light emitting window 131 that transmits the light. In this way, it is easy to emit light in all circumferential directions of the blood leakage detection device 100 with a small number of light emitting elements. However, it is also possible to arrange a plurality of light emitting elements 151 around the body 111 to form the light emitting unit. In this case, each light emitting element 151 can be covered with a cover.

[0030] In this embodiment, the light-emitting unit 130 having the light-emitting window 131 is formed above the operation button 103. In terms of operability, it is preferable to position the blood leakage detection device 100 so that the operation button 103 is at about the eye height of the operator. When positioned in this way, the light-emitting unit 130 is positioned higher than the operation button 103, so that the light-emitting unit 130 is positioned slightly higher than the eye height of the operator, making it easier to see. However, the light-emitting unit 130 can also be formed below the operation button 103.

[0031] In this embodiment, the light emitting unit 130 is formed below the hanging part 102. There is a risk that the portion of the blood leakage detection device 100 above the hanging part 102 may be hidden by the hanging rod or hook when looking up at the blood leakage detection device 100. By forming the light emitting unit 130 below the hanging part 102, it is possible to make it difficult for the light emitting unit 130 to be hidden by the hanging rod or hook. However, depending on the configuration of the hanging part, the light emitting unit 130 may also be formed above the hanging part.

[0032] When the blood leakage detection device 100 is hung near the position of a person's head so that it is unlikely to be hidden by a bed or a dialysis monitoring device and can be easily operated, the top surface 117 is located higher than the height of a person's eyes during use. In this case, if the light-emitting unit 130 is formed on the top surface 117, there is a risk that the light-emitting unit 130 will be hidden in the blind spot of the housing 101 when a person approaches and looks up at the blood leakage detection device 100. By forming the light-emitting unit 130 below the top surface 117 of the body 111, the light-emitting unit 130 will not be hidden by the housing 101 except when looking up at it from directly below, and therefore it can be easily confirmed even when a person approaches and looks up at it.

[0033] When the light-emitting unit 130 is not hidden by the housing 101 when the user approaches and looks up, there is a light-emitting unit viewing point 132 on the light-emitting unit 130, where a virtual line drawn diagonally downward from the light-emitting unit 130 with respect to the vertical axis does not intersect with the housing 101 below the light-emitting unit 130. For example, when the housing 101 is cylindrical and the light-emitting window 131 of the light-emitting unit 130 is formed flush with the surface of the housing 101, at any position of the light unit 130, if the angle θ between the virtual line drawn diagonally downward from the light-emitting unit 130 and the vertical axis is greater than 0°, the virtual line does not intersect with the housing 101 below the light-emitting unit 130. In addition, the light-emitting window 131 of the light-emitting unit 130 is formed so as to go around the body 111, and this relationship holds for virtual lines drawn from almost all points on the light-emitting front part, the light-emitting rear part, the light-emitting right side part, and the light-emitting left side part. Therefore, almost the entire outer surface of the light emitting window portion 131 becomes the light emitting portion visible point 132 .

[0034] It is preferable that the minimum value of θ that does not intersect with the housing 101 below the light-emitting unit 130 is as small as possible, but considering that the blood leakage detection device 100 is placed and used near the position of a person's head, it is preferable to have a point on each side such that the imaginary line does not intersect with the housing 101 below the light-emitting unit 130 when the angle θ between the vertical axis and the imaginary line is 45°. The light-emitting unit 130 can also be formed on the upper side of the top surface 117 so as to satisfy this condition. For example, when the light-emitting unit is provided on the top surface, the condition can be satisfied by making the light-emitting unit non-hemispherical and shaped to match the shape of the housing. Specifically, when the top surface of the housing is rectangular when viewed from the top surface side, the light-emitting unit can also be rectangular, so that the light-emitting unit can be visually recognized when the operator looks up 45 degrees upward. In addition, for example, when the light-emitting unit is provided on the bottom surface of the housing, the condition can be satisfied, and the light-emitting unit can be visually recognized from any position on the four sides. In addition, the condition can be satisfied even when, for example, dome-shaped light-emitting units are formed on the four sides of the housing or when the light-emitting unit is provided at the corner of a rectangular housing. In the embodiment, the light-emitting unit and the housing are formed flush so that the operator does not leave marks on his or her hands when gripping the housing; however, the light-emitting unit 130 may be provided one step recessed from the surface of the housing 101, or conversely, may be provided so as to protrude one step from the surface of the housing 101. Alternatively, the housing 101 may be non-cylindrical and may have a convex portion that protrudes outward below the light-emitting unit 130, or may have a shape that is wider below the light-emitting unit 130.

[0035] In addition, if there is at least one light-emitting unit viewing point 132 on each of the light-emitting front part, the light-emitting rear part, the light-emitting right side part, and the light-emitting left side part, where a virtual line can be drawn that does not intersect with the housing 101 below the light-emitting unit 130, the light-emitting unit 130 can be viewed from any direction around the light-emitting unit 130 when viewed from above. The light-emitting unit viewing point 132 can be located at any position on the outer surface of the light-emitting unit 130. For example, when the light-emitting unit 130 protrudes above the top surface part 117 of the housing 101, if there is a light-emitting unit viewing point 132 on which a virtual line can be drawn that does not intersect with the housing 101 at any one position, such as the most upwardly protruding position or the most lateral protruding position, the light-emitting unit 130 can be viewed without being obstructed by the housing 101. It is preferable that the light-emitting unit viewing points are provided continuously or intermittently along the circumferential direction, and by doing so, the light-emitting unit can be easily confirmed when the blood leakage detection device is viewed from any position in 360 degrees surrounding the light-emitting unit.

[0036] In this embodiment, the light emitting portion 130 is formed so as to go around the angular body portion 111, so that the light emitting front portion, the light emitting rear portion, the light emitting right side portion, and the light emitting left side portion can be clearly distinguished from each other. However, even if the light emitting front portion, the light emitting rear portion, the light emitting right side portion, and the light emitting left side portion are continuous curved surfaces, such as when a cylindrical light emitting portion is formed on a cylindrical body portion, the light emitting front portion, the light emitting rear portion, the light emitting right side portion, and the light emitting left side portion are determined based on the position of the operation button 103.

[0037] In this embodiment, the through hole 102a formed by an inverted U-shaped structure integrated with the housing 101 is used as the suspending part. This configuration can increase the strength of the suspending part 102 and improve the stability when suspended. However, the suspending part 102 is not limited to an inverted U-shape, and can have various configurations that allow the blood leakage detection device 100 to be suspended with the top surface part 117 facing up. For example, it can be an inverted J-shape, an inverted L-shape, an S-shape, or the like. In this embodiment, the uppermost end of the circular through hole 102a of the suspending part 102 is located at the center in the width direction, and the suspending part 102 is molded integrally with the housing 101. By molding the suspending part 102 integrally, the strength of the suspending part 102 can be increased, making it less likely to fall due to breakage. However, the suspending part 102 can also be formed by attaching a member molded separately from the housing 101. In this case, a member other than the housing can be used as the suspending part 102 by providing a hole for inserting a belt, a hanging string, or the like.

[0038] In this embodiment, the detection unit 200 is a sheet having electrode patterns 201, 202, and the electronic device of the blood leakage detection device 100 is configured to detect a change in resistance between the electrode patterns 201, 202 due to blood leakage. However, the detection unit 200 is not limited to this configuration, and various other configurations can be adopted. For example, it can be configured to detect a change in capacitance due to blood leakage, or to optically detect blood leakage. An appropriate circuit for the electronic device can be adopted depending on the detection unit 200.

[0039] In this embodiment, the detection unit 200 and the blood leakage detection device 100 are connected by wire via a connector 203. With this configuration, the detection unit 200 does not need to be provided with a power supply, control circuit, etc., and the detection unit 200 can be simplified. In a configuration in which blood leakage is detected based on the presence or absence of electrical continuity, a wired connection has a large advantage. However, the detection unit 200 provided with a power supply, control circuit, etc. can also be connected by wire. Also, a wireless communication circuit can be provided in both the detection unit 200 and the blood leakage detection device 100, and the detection unit 200 and the blood leakage detection device 100 can be connected wirelessly.

[0040] In this embodiment, the blood leakage detection device 100 is configured to be driven by a replaceable battery such as a dry cell. This configuration eliminates the need for wiring for power, improving the flexibility of the installation location of the blood leakage detection device 100. In addition, since the device can be used immediately by replacing a discharged battery, it is possible to avoid a situation where the device cannot be used in an emergency. The power source of the blood leakage detection device 100 is not limited to a replaceable battery, but can be a built-in battery, a dialysis monitoring device, or a commercial power source. Whatever power source is used, it is preferable to place the heavy power source part of the blood leakage detection device 100 as close to the hanging part 102 as possible. In this embodiment, the battery storage part 155 is located above the substrate 150. This makes it easier to stabilize the blood leakage detection device 100 when it is suspended by the hanging part 102. [Industrial Applicability]

[0041] The blood leakage detection device disclosed herein is easily visible from a distance or when viewed up close, allowing for quick location confirmation, making it useful in the medical field, including dialysis treatment. [Explanation of symbols]
