[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0024] (Overview of medical bed systems)

[0025] Figure 1 and Figure 2 This is a diagram showing an overview of a medical bed system 1 according to an embodiment of the present invention.

[0026] The medical bed system 1 is a system used in hemodialysis treatment. In addition, hemodialysis treatment is sometimes simply referred to as dialysis treatment or dialysis.

[0027] One complication that frequently occurs during dialysis treatment is a drop in blood pressure. The medical bed system 1 of the embodiment is a system that can automatically take measures against a drop in blood pressure during dialysis treatment.

[0028] like Figure 1 As shown, the medical bed system 1 includes a dialysis console 10 and a medical bed 40. A patient who receives dialysis treatment lies on the bed 40. Then, the patient receives dialysis treatment via the console 10.

[0029] (bed)

[0030] The bed 40 includes a mattress 50. The patient lies on a bed surface 52 of the mattress 50. The bed surface 52 is a surface on the upper UD side of the mattress 50 when the bed 40 is installed.

[0031] The bed surface 52 includes a head side bed surface 521 and a lower limb side bed surface 522. The head side bed surface 521 is mainly used for the patient's head, trunk and upper limbs to lie, and the lower limb side bed surface 522 is mainly used for the patient's lower limbs to lie.

[0032] The head side bed surface 521 and the lower limb side bed surface 522 can be tilted. In addition, the tilt angle of the head side bed surface 521 and the tilt angle of the lower limb side bed surface 522 can be set and controlled separately.

[0033] (Console)

[0034] The console 10 functions as a dialysis implementation device. Dialysis conditions can be set from the console 10. In addition, the console 10 has a built-in sphygmomanometer, and can measure blood pressure and record the measured blood pressure.

[0035] The console 10 and the bed 40 are connected by a console connection line 70. The console 10 can send a bed control signal to the bed 40 via the console connection line 70. The bed control signal will be described later.

[0036] By enabling the console 10 to transmit a bed control signal to the bed 40 , the console 10 and the bed 40 can cooperate with each other.

[0037] Through this cooperation, the tilt angle of the bed surface 52 of the bed 40 can be automatically controlled based on the instruction from the console 10 .

[0038] (Lower limb elevation)

[0039] As one of the measures to avoid or restore the blood pressure drop during the above-mentioned dialysis treatment, there is a method of raising the patient's lower limbs. The lower limb raising is a measure of raising the patient's lower legs.

[0040] Limb elevation is a non-invasive, simple, reliable and effective way to avoid or restore blood pressure drop, and has become the first choice in the dialysis treatment area. By raising the lower limbs, the venous blood stored in various organs and capillaries is returned to the circulating blood, increasing the venous circulation volume. As a result, the cardiac output and peripheral vascular resistance are increased, and as a result, blood pressure is increased.

[0041] Figure 1 An overview of lower extremity elevation is shown.

[0042] The lower limb elevation is performed by raising the lower limb side bed surface 522 from the horizontal line HL to the upper side UD. That is, the treatment of raising the lower limb of the patient is performed by raising the lower limb side bed surface 522.

[0043] Specifically, the lower limb side bed surface end portion 522E is lifted upward UD. The lower limb side bed surface end portion 522E is an end portion of the lower limb side bed surface 522 on the opposite side to the head side bed surface 521 .

[0044] (Raise and lower)

[0045] In the following description, raising the bed surface 52 means lifting the bed surface 52 upward UD. Conversely, lowering the bed surface 52 in the direction opposite to the upward UD is referred to as lowering the bed surface 52.

[0046] (Elevation angle)

[0047] The angle formed by the horizontal line HL formed by raising or lowering the floor surface 52 and the floor surface 522 is referred to as the raising angle.

[0048] The elevation angles include an angle formed by the horizontal line HL and the bed surface 521 on the head side and an angle formed by the horizontal line HL and the bed surface 522 on the lower limb side.

[0049] (Lower limb elevation angle)

[0050] Figure 1 The angle formed by the horizontal line HL and the lower limb side bed surface 522 is shown as the lower limb elevation angle A2. Figure 1 The lower limb side bed surface 522 is simulated when the lower limb elevation angle A2 is 20 degrees, 40 degrees, and 60 degrees.

[0051] like Figure 1 As shown, by making the console 10 and the bed 40 cooperate, the lower limb elevation angle A2 can be automatically controlled based on the instruction from the console 10. That is, it is possible to automatically perform treatment for a drop in blood pressure during dialysis treatment.

[0052] Specifically, for example, the patient's blood pressure is measured at predetermined intervals from the start of dialysis treatment, and when the blood pressure is lower than a preset threshold, lower limb elevation can be automatically started. Details will be described later.

[0053] (Connection to bed)

[0054] based on Figure 2 The connection between the console 10 and the bed 40 will be described.

[0055] The medical bed 40 is usually provided with a bed controller 60 for inputting the height and tilt angle of the bed surface 52 of the bed 40 .

[0056] The bed controller 60 and the bed 40 are connected by a controller connection line 72. In addition, the bed 40 includes a receiving port (not shown) as a port for inserting the controller connection line 72.

[0057] Therefore, when the bed 40 includes a plurality of receiving ports, the console 10 and the bed 40 can be connected by inserting the console connection cable 70 from the console 10 into the receiving port.

[0058] (Dispensing Machine)

[0059] When the bed 40 has only one receiving port, it may be considered to connect the console connection line 70 to the controller connection line 72 between the bed controller 60 and the bed 40 .

[0060] Specifically, you can consider using a T-shaped distributor as a repeater.

[0061] The distributor has three connection ports, and inside the distributor, the wiring from each connection port is connected to each other.

[0062] The connection line from the bed controller 60 is connected to one of the three connection ports, the connection line from the console 10 is connected to another connection port, and the connection line to the bed 40 is connected to the remaining connection port.

[0063] Thus, even when the bed 40 has only one receiving port, both the controller connection line 72 and the console connection line 70 can be connected to the bed 40 via the distributor.

[0064] (Other collaboration, other disposal)

[0065] In the above description, the outline of the cooperation between the console 10 and the bed 40 has been described by taking a decrease in the patient's blood pressure and lower limb elevation as a treatment for the decrease in blood pressure as an example.

[0066] However, treatments utilizing the cooperation between the console 10 and the bed 40 include, in addition to lower limb elevation, head elevation and the like.

[0067] In addition, measures corresponding to the patient's blood pressure include, in addition to lower limb elevation, adjustment of the dialysate temperature, and the like.

[0068] Below, after explaining the functional parts of the medical bed system, other treatments are also explained.

[0069] based on Figure 3 To illustrate the composition of each functional part of the medical bed system. Figure 3 This is a functional block diagram showing the functional structure of a medical bed system.

[0070] (Console)

[0071] The console 10 includes a console control unit 12 , a biological information acquisition unit 14 , a treatment determination unit 16 , a liquid temperature control unit 20 , and a console communication unit 18 .

[0072] (Console control unit)

[0073] The console control unit 12 manages and controls the various functional units included in the console 10 .

[0074] (Biological Information Acquisition Department)

[0075] The biological information acquisition unit 14 acquires biological information of the patient. Examples of the biological information include blood pressure, bioelectrical impedance (BIA: Bioelectrical Impedance Analysis), and circulating blood volume (BV: Blood Volume).

[0076] exist Figure 3 In the illustrated configuration, in order to measure the blood pressure of the patient, a blood pressure measurement unit 141 is connected to the biological information acquisition unit 14. A built-in sphygmomanometer provided in the console 10 functions as the blood pressure measurement unit 141.

[0077] The biological information acquisition unit 14 acquires the blood pressure of the patient measured by the built-in sphygmomanometer from the blood pressure measurement unit 141 as biological information.

[0078] Furthermore, the blood pressure monitor may be separate from the console 10 instead of being built in the console 10 .

[0079] Furthermore, when acquiring bioelectrical impedance as the bio-information, a bioelectrical impedance measuring device may be provided, and the bio-information acquiring unit 14 may acquire the value of the bioelectrical impedance measured by the bioelectrical impedance measuring device.

[0080] Furthermore, when the circulating blood volume is acquired as the biological information, a circulating blood volume measuring device may be provided, and the biological information acquiring unit 14 may acquire the value of the circulating blood volume measured by the circulating blood volume measuring device.

[0081] (Disposition Decision Department)

[0082] The treatment decision unit 16 determines whether or not treatment should be performed on the patient based on the biological information acquired by the biological information acquisition unit 14 , and determines the content of the treatment if treatment should be performed.

[0083] (Example of disposal)

[0084] exist Figure 3 In the illustrated configuration, as described above, the patient's blood pressure is acquired as biological information.

[0085] As measures for fluctuations in blood pressure during dialysis treatment, there are raising and lowering the bed surface 52 of the bed 40 and changing the liquid temperature of the dialysate.

[0086] Specifically, as treatment for a drop in blood pressure, the patient's lower limbs can be raised by raising the lower limb side bed surface 522, and the temperature of the dialysate can be lowered. In addition, as treatment for a rise in blood pressure, the patient's head can be raised by raising the head side bed surface 521, and the temperature of the dialysate can be increased.

[0087] exist Figure 3 In the illustrated configuration, the treatment determination unit 16 includes a lifting angle determination unit 161 and a fluid temperature determination unit 162 .

[0088] The lifting angle determination unit 161 determines whether the bed surface 52 needs to be lifted or lowered based on the bed position information signal, and if necessary, determines which of the head side bed surface 521 or the head side bed surface end 521E is to be lifted or lowered and the angle of the lift or lowering.

[0089] On the other hand, the liquid temperature determiner 162 determines whether the liquid temperature of the dialysate needs to be changed, and determines the temperature change range if necessary.

[0090] (Liquid temperature control unit)

[0091] The liquid temperature control unit 20 changes the temperature of the dialysate according to the content of the treatment determined by the liquid temperature determination unit 162 , that is, how many degrees the temperature of the dialysate is to be increased or decreased.

[0092] (Console Communication Department)

[0093] The console communication unit 18 transmits a bed position information signal and a bed control signal to a bed communication unit 46 described later.

[0094] The bed position information signal is a signal including current angle information of the bed surface on the head side and the lower limb side of the bed.

[0095] The bed control signal is a signal including information on the content of the treatment determined by the raising angle determination unit 161 , that is, on which of the head-side bed surface 521 and the lower limb-side bed surface 522 is to be raised or lowered by how many degrees.

[0096] exist Figure 3 In the illustrated configuration, the console communication unit 18 and the bed communication unit 46 are connected by a console connection line 70 .

[0097] However, the connection between the console communication unit 18 and the bed communication unit 46 is not limited to the connection via the console connection line 70. Other wired connections may be used. In addition, the connection between the console communication unit 18 and the bed communication unit 46 may also be wireless.

[0098] (bed)

[0099] Next, the bed 40 will be described.

[0100] The bed 40 includes a bed control unit 42 , a bed tilt control unit 44 , and a bed communication unit 46 .

[0101] (Bed Control Unit)

[0102] The bed control unit 42 manages and controls the functional units included in the bed 40 .

[0103] (Bed Communication Department)

[0104] The bed communicator 46 receives a bed position information signal and a bed control signal from the console communicator 18 and an instruction signal from the bed controller 60. The instruction signal will be described later.

[0105] In addition, as described above, the receiving port of the bed 40 can also be used as the bed communication unit 46 .

[0106] (Bed tilt control unit)

[0107] The bed tilt control unit 44 raises or lowers the bed surface 52 based on the content of the bed control signal received by the bed communication unit 46 from the console communication unit 18 .

[0108] (Ministry of Information)

[0109] The medical bed system 1 may also include a notification unit 22. The notification unit 22 is connected to the console control unit 12, and when the elevation angle determination unit 161 of the treatment determination unit 16 receives the bed position information signal, it displays it on the screen of the dialysis device or outputs a buzzer sound when it is determined that it cannot be further elevated.

[0110] (Bed Controller)

[0111] As described above, the bed controller 60 is a terminal attached to the bed 40 for inputting the height and tilt angle of the bed surface 52 of the bed 40. Information on the bed 40 input to the bed controller 60 is input from the bed controller 60 to the bed communicator 46 as an instruction signal.

[0112] The bed controller 60 and the bed communicator 46 are connected by a controller connection line 72. The connection between the bed controller 60 and the bed communicator 46 can also be made a wireless connection similar to the connection between the console communicator 18 and the bed communicator 46.

[0113] Each of the aforementioned functional units may be constituted by a plurality of functional modules, but the functional modules do not necessarily need to be physically separated, and one CPU may realize the functions of a plurality of functional modules.

[0114] In addition, each functional unit may be separately configured in two or more places in consideration of the configuration with other functional units, etc. Alternatively, one functional module may be separately configured in two or more places and controlled in a decentralized manner. Each functional unit may also include a storage unit, which may be composed of various recording media.

[0115] The various functions of each functional unit may be realized by, for example, executing a program stored in the storage unit.

[0116] Each function of each functional unit may be realized by cooperation of hardware and software, or may be realized only by hardware electronic circuits.

[0117] (Treatment for hypotension and hypertension)

[0118] Treatment based on the patient's blood pressure during dialysis treatment will be described while including the relationship with the above-mentioned functional units.

[0119] In the medical bed system 1 , in response to changes in the patient's blood pressure during dialysis treatment, the following measures are mainly taken: raising or lowering the bed surface 52 , lowering or raising the temperature of the dialysate, and shortening the blood pressure measurement interval.

[0120] Specifically, as a treatment to increase blood pressure, elevating the patient's lower limbs and lowering the temperature of the dialysate are cited. Conversely, as a treatment to lower blood pressure, elevating the patient's head and increasing the temperature of the dialysate are cited.

[0121] (low blood pressure before dialysis starts and blood pressure drop after dialysis starts)

[0122] The following is a more specific description.

[0123] When the patient's blood pressure is low before the start of dialysis or when the patient's blood pressure drops after the start of dialysis, treatments such as raising the patient's lower limbs and lowering the temperature of the dialysate are performed.

[0124] As previously based on Figure 1 As described above, the patient's lower limbs are raised by raising the lower limb side bed surface 522 of the bed 40. The raising is performed by the bed tilt control unit 44 connected to the bed control unit 42.

[0125] On the other hand, the temperature of the dialysate is lowered by the liquid temperature control unit 20 connected to the console control unit 12 .

[0126] (Blood pressure rise after dialysis starts)

[0127] Next, the treatment for the increase in blood pressure after the start of dialysis will be described.

[0128] When the patient's blood pressure rises after the start of dialysis, treatments such as raising the patient's head and increasing the temperature of the dialysate are performed.

[0129] Based on the previous reference Figure 2 To illustrate raising the patient's head, i.e., head elevation.

[0130] (Head raised)

[0131] Head elevation is the process of raising the patient's head.

[0132] The head is lifted by lifting the bed surface 521 on the head side from the horizontal line HL to the upper side UD. That is, the treatment of lifting the patient's head is performed by lifting the bed surface 521 on the head side.

[0133] Specifically, the head side bed surface end portion 521E is lifted upward UD. Here, the head side bed surface end portion 521E is an end portion of the head side bed surface 521 on the opposite side to the lower limb side bed surface 522.

[0134] (Head elevation angle)

[0135] Figure 2 The angle formed by the horizontal line HL and the head-side bed surface 521 is shown as the head lifting angle A1.

[0136] The head-side bed surface 521 is raised by the bed tilting control unit 44 connected to the bed control unit 42 . The bed tilting control unit 44 controls the head lifting angle A1 based on a change instruction of the head lifting angle A1 included in the bed control signal received from the console 10 .

[0137] The console 10 and the bed 40 cooperate with each other, so that the head elevation angle A1 can be automatically controlled based on instructions from the console 10 .

[0138] This makes it possible to automatically handle not only a drop in blood pressure during dialysis treatment but also a rise in blood pressure.

[0139] Increasing the temperature of the dialysate is performed by the liquid temperature control unit 20 connected to the console control unit 12 in the same manner as decreasing the temperature of the dialysate.

[0140] (Blood pressure measurement interval)

[0141] When the aforementioned treatment is performed for a decrease in blood pressure, an increase in blood pressure, or the like, it is preferable to shorten the interval for measuring the patient's blood pressure thereafter. This is because it is preferable to carefully observe the effect of the treatment on the patient.

[0142] (Process of dialysis treatment)

[0143] based on Figure 4To illustrate the process of dialysis treatment of medical bed system 1. Figure 4 is a flowchart showing the flow of dialysis treatment.

[0144] In the dialysis treatment described below, the threshold value of the blood pressure drop that requires treatment, which occurs after the start of the dialysis treatment, is set to 120 mmHg.

[0145] The process of dialysis treatment is explained step by step.

[0146] In the following description, dialysis treatment is sometimes referred to as dialysis. In addition, for example, S1 represents step 1, and S2 represents step 2. In addition, actions not specifically described with respect to the action subject are performed by the console control unit 12 or the bed control unit 42. Figure 5 The same is true in the description of .

[0147] (S1)

[0148] In S1, dialysis is started.

[0149] (S2)

[0150] It is determined whether the patient's blood pressure before the start of dialysis is 120 mmHg or more.

[0151] When the blood pressure is 120 mmHg or higher, the process proceeds to S3 , and when the blood pressure is less than 120 mmHg, the process proceeds to S7 .

[0152] The blood pressure is measured by the blood pressure measurement unit 141 and the biological information acquisition unit 14 .

[0153] (S3)

[0154] Since the patient's blood pressure before the start of dialysis is 120 mmHg or more, it is determined whether the blood pressure is less than 120 mmHg during dialysis.

[0155] The patient's blood pressure was measured at intervals of 30 minutes, and it was determined whether the blood pressure was less than 120 mmHg at each measurement.

[0156] When the patient's blood pressure drops to less than 120 mmHg, the process proceeds to S4, and the patient receives treatment for the drop in blood pressure.

[0157] When the patient's blood pressure does not drop below 120 mmHg, the dialysis is continued as it is, and after the dialysis is continued for a predetermined time, the dialysis is terminated in S11.

[0158] The decision on whether treatment is necessary or not is made by the treatment decision unit 16 .

[0159] (S4)

[0160] Since the patient's blood pressure has dropped to less than 120 mmHg, treatment for the drop in blood pressure is performed.

[0161] Specifically, the patient's lower limbs were raised by 20 degrees. In addition, the temperature of the dialysate was lowered from 36.5° C. to 35.5° C. Furthermore, the interval for measuring the patient's blood pressure was shortened from 30 minutes to 15 minutes.

[0162] The treatment content is determined by the treatment determination unit 16, the elevation angle determination unit 161, and the fluid temperature determination unit 162. The lower limbs are elevated by the bed tilt control unit 44, and the fluid temperature of the dialysate is changed by the fluid temperature control unit 20.

[0163] When the treatment is completed, the process proceeds to S5.

[0164] (S5)

[0165] After the treatment for the drop in blood pressure is performed in S4, it is determined whether the patient's blood pressure has risen to 120 mmHg or more. The interval for measuring the patient's blood pressure is set to 15 minutes.

[0166] When the patient's blood pressure rises to 120 mmHg or more, dialysis is continued as it is, and after dialysis is continued for a predetermined time, dialysis is terminated in S11.

[0167] If the patient's blood pressure has not risen to 120 mmHg or more, the process proceeds to S6, and the patient receives further treatment to lower his blood pressure.

[0168] The blood pressure is measured by the blood pressure measurement unit 141 and the biological information acquisition unit 14 .

[0169] (S6)

[0170] Since the patient's blood pressure does not rise to 120 mmHg or more even after receiving the treatment in S4, further treatment is performed to lower the blood pressure.

[0171] Specifically, the angle of elevation of the patient's lower limbs was increased from 20 degrees to 30 degrees. In addition, the temperature of the dialysate was reduced from 35.5°C to 35.0°C.

[0172] The treatment content is determined by the treatment determination unit 16, the elevation angle determination unit 161, and the fluid temperature determination unit 162. The lower limbs are elevated by the bed tilt control unit 44, and the fluid temperature of the dialysate is changed by the fluid temperature control unit 20.

[0173] When the treatment is completed, the dialysis is continued as it is, and after the dialysis is continued for a predetermined time, the dialysis is terminated in S11.

[0174] (S7)

[0175] Next, a case where it is determined in S2 that the patient's blood pressure before the start of dialysis is less than 120 mmHg will be described.

[0176] When the above determination is made, the process proceeds from S2 to S7.

[0177] In S7, it is determined whether the patient's blood pressure before the start of dialysis is less than 100 mmHg.

[0178] When the blood pressure is not less than 100 mmHg, no special treatment for hypotension is performed, and the process proceeds to S3 for dialysis.

[0179] If the blood pressure is less than 100 mmHg, the process proceeds to S8, and the patient receives treatment for hypotension.

[0180] The blood pressure is measured by the blood pressure measurement unit 141 and the biological information acquisition unit 14 .

[0181] (S8)

[0182] Since the patient's blood pressure was less than 100 mmHg, treatment for hypotension was performed.

[0183] Specifically, the patient's lower limbs were raised by 20 degrees. In addition, the temperature of the dialysate was lowered from 36.5° C. to 35.5° C. Furthermore, the interval for measuring the patient's blood pressure was shortened from 30 minutes to 15 minutes.

[0184] The treatment content is determined by the treatment determination unit 16, the elevation angle determination unit 161, and the fluid temperature determination unit 162. The lower limbs are elevated by the bed tilt control unit 44, and the fluid temperature of the dialysate is changed by the fluid temperature control unit 20.

[0185] When the treatment is completed, the process proceeds to S5. The subsequent flow is the same as when the determination in S2 is "yes".

[0186] (Treatment for elevated blood pressure)

[0187] The above mainly describes the treatment of the patient's hypotension at the start of dialysis and the drop in blood pressure after the start of dialysis. The following describes the treatment of the patient's increased blood pressure.

[0188] The medical bed system 1 can also make the console 10 and the bed 40 cooperate with each other for treatment of blood pressure rise. Through this cooperation, treatment of blood pressure rise can be automatically performed in conjunction with blood pressure rise. Specifically, based on instructions from the console 10, the inclination angle of the bed surface 52 of the bed 40 is automatically controlled.

[0189] based on Figure 5 The following describes the process of treating elevated blood pressure during dialysis treatment performed by the medical bed system 1 . Figure 5 is a flowchart showing the flow of dialysis treatment.

[0190] In the dialysis treatment described below, the threshold value of the blood pressure increase requiring treatment is set to 180 mmHg.

[0191] The process of dialysis treatment is explained step by step.

[0192] (S21)

[0193] In S21, dialysis is started.

[0194] (S22)

[0195] Determine whether the patient's blood pressure rises above 180 mmHg during dialysis.

[0196] The patient's blood pressure was measured at intervals of 30 minutes, and it was determined whether the blood pressure was 180 mmHg or higher at each measurement.

[0197] When the patient's blood pressure does not rise to 180 mmHg or more, dialysis is continued as it is, and after dialysis is continued for a predetermined time, dialysis is terminated in S26.

[0198] When the patient's blood pressure rises to 180 mmHg or more, the process proceeds to S23, and the patient receives treatment for the rise in blood pressure.

[0199] The blood pressure is measured by the blood pressure measurement unit 141 and the biological information acquisition unit 14 .

[0200] (S23)

[0201] Since the patient's blood pressure has risen to 180 mmHg or more, treatment for the increased blood pressure is performed.

[0202] Specifically, the patient's head was raised by 20 degrees. In addition, the temperature of the dialysate was raised from 36.5° C. to 36.8° C. Furthermore, the interval for measuring the patient's blood pressure was shortened from 30 minutes to 15 minutes.

[0203] The treatment content is determined by the treatment determination unit 16, the elevation angle determination unit 161, and the liquid temperature determination unit 162. In addition, the bed tilt control unit 44 is used to lift the head, and the liquid temperature control unit 20 is used to change the liquid temperature of the dialysate.

[0204] When the treatment is completed, the process proceeds to S24.

[0205] (S24)

[0206] After the treatment for the increase in blood pressure is performed in S23, it is determined whether the patient's blood pressure has dropped to 160 mmHg or less. The interval for measuring the patient's blood pressure is set to 15 minutes.

[0207] If the patient's blood pressure has not dropped below 160 mmHg, dialysis is continued as it is, and after dialysis is continued for a predetermined time, dialysis is terminated in S26. That is, dialysis is continued while maintaining treatment for the increase in blood pressure.

[0208] When the patient's blood pressure drops to 160 mmHg or less, the process proceeds to S25 to cancel the treatment for the increased blood pressure.

[0209] The blood pressure is measured by the blood pressure measurement unit 141 and the biological information acquisition unit 14 .

[0210] (S25)

[0211] Since the patient's blood pressure has dropped below 160 mmHg, the treatment for the elevated blood pressure is cancelled.

[0212] Specifically, the patient's head was raised and returned to its original position. That is, the head was lowered by 20 degrees. In addition, the temperature of the dialysate was lowered from 36.8°C to 36.5°C. Furthermore, the interval for measuring the patient's blood pressure was returned from 15 minutes to 30 minutes.

[0213] The treatment content is determined by the treatment determination unit 16, the elevation angle determination unit 161, and the liquid temperature determination unit 162. In addition, the bed tilt control unit 44 is used to lift the head, and the liquid temperature control unit 20 is used to change the liquid temperature of the dialysate.

[0214] When the treatment is completed, the process returns to S22.

[0215] An embodiment of the medical bed system 1 has been described above. In addition, various changes can be added to the above-mentioned embodiment of the medical bed system 1.

[0216] (Setting of blood pressure threshold)

[0217] The blood pressure threshold can be set to a predetermined value determined by the patient's treatment status. Here, the predetermined value can be set to a blood pressure drop threshold that is considered necessary to deal with the blood pressure drop that occurs after the start of dialysis in many dialysis patients. Specifically, it can be set to 120 mmHg.

[0218] In addition, the blood pressure threshold can also be determined based on the blood pressure value of a patient obtained before dialysis. Moreover, the blood pressure threshold can also be determined based on the lowest value, the highest value or the average blood pressure value during the most recent dialysis treatment of the same patient. In addition, the blood pressure threshold can also be determined based on the patient's age, gender, body shape, previous illness, etc. In the case of setting the blood pressure threshold according to the individual conditions of the patients in this way, it is also possible to use an ID (Identification) number or the like to associate the patient with their respective conditions, and use the ID number to set the blood pressure threshold.

[0219] In addition, as a threshold value, BIA (bioelectric impedance) can also be used as an index other than blood pressure.

[0220] Furthermore, for example, the amount of change in a value such as ΔBP (blood pressure change) or a rate of change such as a decay rate of a value may be used as the threshold value instead of the absolute value.

[0221] Furthermore, it is also possible to perform treatment for a drop in blood pressure in conjunction with a decrease in the amount of circulating blood.

[0222] In addition, a blood pressure increase threshold value that can cope with the blood pressure increase can also be set in the same manner.

[0223] (Content of disposal)

[0224] As treatments for a drop in blood pressure, lower limb elevation, lowering of the dialysate temperature, etc. have been described, but the treatments that can be taken are not limited to these, and for example, the treatments may include changing the amount of water removed, such as reducing the amount of water removed.

[0225] In addition, the change of the elevation angle of the bed surface 52 and the change of the liquid temperature of the dialysate do not need to be performed at the same time. One of them may be performed with priority over the other.

[0226] (Confirm operation)

[0227] The description has been made of the automatic execution of treatment for a drop in blood pressure or the like in conjunction with the blood pressure value through the cooperation between the console 10 and the bed 40 .

[0228] However, it is also possible to set a confirmation operation before taking action.

[0229] Specifically, when the blood pressure value is lower than the threshold, the console 10 may be caused to display a confirmation screen, and a confirmation operation may be required before treatment. This allows treatment of the patient to be performed semi-automatically while preventing erroneous treatment.

[0230] The sphygmomanometer is not limited to being built in the console 10, and may be provided as a separate body from the console 10. In this case, the sphygmomanometer and the console 10 can be connected by a communication cable.

[0231] The distributor and repeater described in connection with the connection between the console 10 and the bed 40 are not limited to the above, and can be appropriately changed based on the specifications of the console and the bed. By setting the specifications of the cables, sockets, distributors, repeaters, etc. to specifications that can be connected between different specifications, that is, to specifications that can be converted, it is possible to bridge the differences in manufacturers and specifications of the console and the bed, so that the console and the bed can be connected and linked.

[0232] The console 10 can send a control signal for controlling the device to the bed 40 or a device other than the bed 40 that has a bed surface 52 on which the patient lies. Therefore, the console 10 can be used alone as a control device for controlling various devices that have a bed surface 52.

[0233] In the medical bed system 1 of the present invention, as described above, the console 10 cooperates with the bed 40. Therefore, the bed can be automatically or semi-automatically controlled to raise the lower limbs, raise the head, etc. in conjunction with the patient's condition, such as when the patient's blood pressure reaches an arbitrary upper limit or lower limit, or when the blood pressure attenuation rate reaches a specified value.

[0234] Conventionally, the acquisition of a patient's blood pressure is not linked to treatments such as lower limb elevation. Furthermore, the acquisition of blood pressure is performed as follows.

[0235] That is, in order to change the dialysis conditions according to the blood pressure and record the blood pressure via the console, the blood pressure during dialysis is generally acquired using a sphygmomanometer built into the console.

[0236] On the other hand, treatments such as lower limb elevation use a wired controller (bed controller) of the bed on which the patient lies. The bed controller is often arranged at the side of the bed opposite to the control console to prevent blood contamination caused by dialysis and not to interfere with the dialysis process.

[0237] Therefore, when the blood pressure console and the bed are not linked, the dialysis staff obtains blood pressure through the console. If the blood pressure is found to be outside the specified range, that is, exceeds the specified threshold, they need to move to the opposite side of the bed after operating the console to perform bed controls such as raising the lower limbs.

[0238] That is, the current situation is that every time a procedure such as lower limb elevation, which is most commonly used in dialysis treatment, is performed, dialysis staff are required to perform an action that involves movement around the bed.

[0239] This is a huge burden on dialysis staff.

[0240] Therefore, in the present invention, when the console 10 and the bed 40 cooperate and the blood pressure value is linked to the treatment therefor, and the bed control can be automatically or semi-automatically performed, the burden on the dialysis staff is greatly reduced.

[0241] As a result, the dialysis staff has extra time to respond to other patients' severe hypotension requiring vasopressors or to perform other various patient care.

[0242] This makes it easier to cope with the increase in dialysis patients and the shortage of dialysis staff, and can suppress the decline in the quality of patient care and the fatigue of dialysis staff caused by the burden.
