[0076] <Mounting section 60>

[0077] The mounting portion 60 is configured to enable the medical device 100 to be mounted on a hemostatic site of a patient. Figure 2The device shown includes a frame 61 and a winding portion 62. A compression portion (not shown) for hemostasis is provided on the inner side of the winding portion 62 that contacts the patient, and the compression portion is installed in a manner aligned with the hemostasis site (puncture site) of the patient. The compression portion is a balloon-shaped structure that expands by filling with a fluid such as air and can compress the wound of the hemostasis site. Alternatively, the winding portion 62 itself is composed of a soft hollow component, or it can be a compression portion that can adjust the compression amount by filling with a fluid. The frame 61 can include a material such as metal that carries the hardware (device or component group) 1 that constitutes the power supply unit 10, the acquisition unit 20, the notification unit 30, the communication unit 40, and the control unit 50.

The winding portion 62 is configured to be adjustable according to the circumference of the installation site of the hemostasis site of the patient. For the above-mentioned various sensors, the sensors capable of wired or wireless communication with the acquisition unit 20 built in the frame 61 can be installed on the patient as a device different from the installation unit, or can be set on the surface of the frame on the patient's body surface side. The electrode 21 is an electrode for acquiring biological information. The electrodes (not shown) arranged on the back side of the frame 61 are paired, and a weak current flows from one electrode to the other electrode.

[0078] The winding portion 62 is, for example, in the shape of a watch wristband, and is configured to have an internal space that can be filled with and released fluid so as to change the circumference inside. The internal space of the winding portion is connected to a tube (not shown) or the like and to a portable pump (not shown) or the like, and the fluid filling amount relative to the compression portion can be adjusted individually. The control portion 50 can calculate / adjust the amount of compression applied to the patient's hemostatic area at one o'clock during installation, corresponding to the filling amount that can be adjusted by the supply / discharge of fluid such as air sent into the compression portion. It should be noted that the material of the installation portion is not particularly limited. As an example, the frame 61 can be made of metal such as stainless steel, and the winding portion 62 and the compression portion can be made of soft plastic materials, etc.

[0079] <Server 200>

The server 200 can securely communicate the patient's biological information, which can be achieved by the company's resources (local), or by using the resources of other companies in the form of cloud services, or by using the resources of the company and other companies at the same time (hybrid).

[0081] (Adjustment of the compression method)

[0082] Next, adjustment of the compression method of the puncture site of a patient using medical system 1 of the present embodiment will be described. Figure 4 This is a flowchart for explaining the adjustment of the compression method using the medical system 1 according to the first embodiment.

[0083] After the patient has undergone surgery with the radial artery, which is an upper limb artery, as the puncture site, the surgeon installs the medical device 100 on the wrist, which is the puncture site, in the operating room. Then, the patient is transferred from the treatment room to the general ward, etc., and the medical practitioner such as a physician performs the initial settings of the medical device 100 in the observation room. The initial settings are the timing of the acquisition unit 20 sensing (for example, every two hours), the setting of the intervention means such as the notification unit 30, etc., and are set by the medical practitioner.

[0084] Sensing can include peripheral body temperature sensing, upper arm edema sensing, heart rate sensing, blood pressure sensing, pulse sensing, bleeding sensing, pain sensing, etc. As for the above-mentioned sensing, the medical practitioner determines which sensing to make function at the moment of installing the medical device 100. For example, in the case of patients with low bleeding risk, peripheral blood circulation sensing and hematoma sensing can be set to ON. In the case of patients with complications of hypertension, peripheral blood circulation sensing, hematoma sensing, and blood pressure sensing can be set to ON. The interventions described below can be performed after the patient is discharged from the hospital to his home, etc.

[0085] First, the medical device 100 measures the temperature of the patient's peripheral part using the temperature sensor of the acquisition unit 20 (acquisition of biological information, ST1). The measurement timing of the temperature sensor can be set to once every two hours as an example.

[0086] Here, when the temperature measured at every set time is 36.0 degrees or more and exceeds the third threshold value V3 (ST2: No), the control unit 50 determines that the risk of anemia is low and records the temperature measurement result in the acquisition unit 20 (ST3).

[0087] When the measurement result is less than or equal to the third threshold value V3 (ST2: YES), the control unit 50 determines that the risk of anemia is high (ST4), and causes the sensor of the acquisition unit 20 for detecting oxygen saturation to measure the oxygen saturation of the patient (acquisition of biological information, ST5). The measurement principle of oxygen saturation can adopt a known measurement principle using the above-mentioned optical sensor or the like.

[0088] Here, when the measured oxygen saturation exceeds the second threshold value V2 set to 95 (%) or the like (ST6: Yes), the control unit 50 records the measured oxygen saturation in the acquisition unit 20 (ST7). On the contrary, when the measured oxygen saturation is less than the second threshold value V2 (ST6: No), the control unit 50 records the measured oxygen saturation in the acquisition unit 20, calculates a compression protocol corresponding to the oxygen saturation, and adjusts the compression method based on the calculated compression protocol (ST8).

[0089] The compression protocol stores data such as the compression time, compression intensity, decompression time interval, and decompression amount per time in the acquisition unit 20, and the control unit 50 selects / sets an appropriate decompression interval and decompression amount per time according to the referenced oxygen saturation. For example, after a predetermined time has passed since the start of hemostasis (compression), Figure 4 As shown in ST4 of , when the risk of anemia is high and the pressure is adjusted in stages, if the oxygen saturation exceeds 95%, the pressure is reduced by 1 stage of decompression for the filling amount of the fluid filled in the compression part at the beginning of hemostasis. The state in which the compression part is filled with fluid at the beginning of hemostasis can be called the initial state. In addition, if the oxygen saturation is 90% to 95%, the pressure is reduced by 2 stages of decompression for the initial state. In addition, if the oxygen saturation is below 90%, it can be set to reduce the pressure by 3 stages of decompression for the initial state. As a change to the compression protocol, the pressure in the initial state is relatively too large. In order to avoid complications caused by long-term compression of the pressure, the patient's peripheral blood circulation and bleeding conditions can be confirmed, the optimal pressure is calculated at regular intervals, and the pressure is increased or decreased (adjusted) based on the calculated value.

[0090] (Intervention for internal bleeding)

[0091] Figure 5 This is a flowchart explaining intervention for internal bleeding. In PCI surgery using the radial artery as the puncture site, the arterial wall may be damaged when the guidewire, sheath, or other equipment passes through the artery, causing internal bleeding after the surgery. Figure 5 This is performed as an intervention against such risks of internal bleeding.

[0092] As for the risk of internal bleeding, damage to blood vessels may change depending on the outer diameter of the sheath used in the operation and the type of chip at the front end of the guide wire. In addition, the susceptibility of internal bleeding may change depending on the inner diameter of the patient's arterial blood vessels and the degree of hardening of the blood vessels. The control unit 50 enables the acquisition unit 20 to acquire information such as the outer diameter of long tubular components such as sheaths used in operations with the radial artery as the puncture site and information such as the patient's blood vessel diameter (acquisition of biological information, ST11). This information is recorded in a server 200 accessible to the medical device 100 by medical practitioners such as doctors through electronic devices that can communicate, such as PCs (Personal Computers) before the operation on the patient with the radial artery as the puncture site is completed and the patient is discharged from a medical institution. The medical device 100 accesses the server 200 via the communication unit 40 to obtain the above information.

[0093] Furthermore, the control unit 50 calculates data required to determine how high the risk of internal bleeding is due to surgery through the radial artery, etc. Specifically, the control unit 50 calculates the size value of the equipment used in the surgery based on the sheath, catheter, guide wire, etc. as a risk score (ST12). As an example, more specifically, from the perspective of the risk of complications after PCI, when the sheath used in the surgery uses a 6Fr or more or the front end chip uses a harder wire, the risk score is added. On the other hand, when the sheath is less than 5Fr or when a soft front end chip wire is used, the risk score is not added. Generally, the larger the sheath diameter, the greater the risk of damage to the blood vessel inserted into the sheath. In addition, the hardness of the front end chip varies according to the soft length of the front end, or can become soft according to the structure, material, etc. such as the coil structure. For example, the product name of the commercially available guide wire, the information data related to the hardness of the product soft wire and the front end chip are pre-stored in the server 200, and the medical practitioner can automatically add points to the risk score by inputting the product information of the guide wire.

[0094] Then, the control unit 50 determines whether the calculated score (first score) is equal to or greater than the first threshold value V1.

[0095] When the score calculated based on the size of the sheath, catheter, guidewire and other equipment used in the operation is below the first threshold value V1 (ST13: No), the risk of internal bleeding is low, and the subsequent operation is not performed, and information such as the sheath outer diameter is recorded in the acquisition unit 20 (ST14).

[0096] When the score becomes greater than the first threshold value V1 (ST13: Yes), the control unit 50 determines that the risk of internal bleeding is high (ST15), and causes the notification unit 30 to prompt a proposal to intervene in the patient for internal bleeding (ST16). Specifically, the notification unit 30 performs at least one of a touch screen and voice notification to install an internal bleeding treatment device such as a compression arm cover. By having the patient install the compression arm cover around the puncture site, the site can be protected and the symptoms of internal bleeding can be reduced. In addition, the control unit 50 can be configured to contact the patient's relatives, etc., by email, etc., when it is determined that intervention related to internal bleeding is required.

[0097] In addition, the control unit 50 notifies the notification unit 30 through at least one of the touch screen and voice to temporarily reduce the dosage of the anticoagulant taken after the operation or temporarily stop taking it (ST17). This can alleviate the symptoms of internal bleeding.

[0098] In the medical device 100 , when the measurement value of at least one of the body fluid state by the sweat sensor, the water sensor, or the humidity sensor is lower than each threshold value of the body fluid amount, the control unit 50 can cause the notification unit 30 to notify the recommendation of water intake.

[0099] It should be noted that, refer to Figure 4 , Figure 5 The compression method adjustment and anticoagulant adjustment described above can be performed multiple times at set time intervals. Therefore, if it is determined that the compression method adjustment and anticoagulant adjustment are not necessary in a certain measurement, it may be determined that at least one of the compression method adjustment and anticoagulant adjustment is necessary in subsequent measurements.

[0100] in addition, Figure 4 , Figure 5 The contents of the compression method adjustment and anticoagulant adjustment shown in the flowchart can be recorded as a program in the acquisition unit 20. The above-mentioned program can be recorded in the medical device in advance, or can be configured to be downloaded from the server 200 by the wearer.

[0101] As described above, in the medical system 1, the medical device 100 includes an acquisition unit 20, a control unit 50, and a notification unit 30. The acquisition unit 20 acquires a plurality of biological information related to the state of a patient who has undergone an upper limb artery puncture operation. The control unit 50 is configured to be able to adjust a compression method for stopping bleeding of the patient based on a plurality of biological information related to the state of the patient acquired from the acquisition unit 20. The notification unit 30 is configured to be able to notify an intervention method based on the biological information. The medical device 100 is configured to be attachable to the patient's wrist. The medical device 100 is configured to carry a program that implements the functions of the acquisition unit 20, the control unit 50, and the notification unit 30.

[0102] For patients who have undergone the above-mentioned TR approach surgery, medical practitioners confirm the bleeding status of the radial puncture point, the blockage status of the arterial blood vessels, edema of the upper arm, peripheral blood circulation, and the patient's pain through palpation, visual observation, and interviews. Based on the results of the examination, medical practitioners comprehensively judge the content of the patient's postoperative management and adjust prescriptions such as medication, compression of hemostatic devices, and examinations. For postoperative patients, it is possible to adjust the compression of hemostatic devices, adjust medication, and wear a fastening belt on the upper arm. Here, based on the experience of medical practitioners, the judgment of risks and interventions regarding the bleeding status, edema of the upper arm, and peripheral blood circulation of postoperative patients may change. In order to improve the efficiency of the above-mentioned clinical operations and the accuracy of postoperative management, it is hoped that the patient's condition can be judged comprehensively and accurately, and intervention can be performed appropriately.

[0103] In this regard, in the present embodiment, as described above, the medical system 1 confirms the patient's vital signs and the like in various aspects based on a plurality of information, and adjusts the hemostasis method and the like based on the judgment of the patient's condition. By configuring in this manner, it is possible to improve the care of the patient after the necessary surgery for the lesion site from the puncture site such as the radial artery, and prevent complications. In addition, the data acquisition of the medical device 100 can automatically collect the information required for judgment at a set interval, etc.

[0104] By automatically collecting the information required for judgment in this way, the work burden of medical practitioners can be reduced. In addition, the judgment method is performed in many aspects according to the criteria recorded in the acquisition unit 20, etc., and since it is not human, it can provide patients with a better medical experience. In addition, by automatically collecting the above information, even if it is not a medical institution such as a hospital, the patient can use the medical device 100 with peace of mind without relying on medical practitioners.

[0105] The control unit 50 is configured to calculate a compression protocol that defines a compression method and adjust the compression method based on the compression protocol. By configuring in this way, the compression method can be adjusted to accurately reflect the plurality of biological information acquired by the acquisition unit 20 .

[0106] In addition, the acquisition unit 20 acquires the first information, which includes at least one of the outer diameter of the medical device such as a sheath used in the operation inserted into the patient and the diameter of the patient's blood vessel. The notification unit 30 is configured to notify the intervention method of internal bleeding, etc. when the score calculated based on the first information is greater than the first threshold value V1. By configuring in this way, intervention other than compression of the hemostatic site can be performed, thereby improving the postoperative patient care and preventing complications.

[0107] In addition, when the oxygen saturation of the patient becomes less than the second threshold value V2, the control unit 50 adjusts the compression method in a manner changed from the initial setting. By configuring in this way, the compression method of the hemostatic site can be adjusted according to the latest health status of the patient, thereby improving postoperative patient care and preventing complications.

[0108] In addition, the comparison between the patient's oxygen saturation and the second threshold value V2 is performed when the patient's peripheral temperature is below the third threshold value V3. By configuring in this way, the necessity of changing the compression method can be determined based on the possibility that the risk of anemia is high, thereby improving the adjustment accuracy of the compression method.

[0109] In addition, the medical system 1 is configured such that the acquisition unit 20 records the compression method of the control unit 50 and the intervention method notified to the patient. By configuring in this way, clinical data can be accumulated toward standardization of postoperative patient management and information as evidence of management methods can be collected.

[0110] (Variation 1 of the first embodiment)

[0111] Figure 6 This is a flowchart for determining the adjustment of the compression method of a variant of the first embodiment. In the first embodiment, it is described that the compression method is adjusted when the patient's peripheral temperature is measured and the risk of anemia may be high and when the oxygen saturation is above a threshold. However, the adjustment determination of the compression method can also be implemented as follows. It should be noted that in this variant, the adjustment of the compression protocol is different from the first embodiment and includes the determination of the anticoagulant adjustment (see Figure 5 ) The other contents are the same as those of the first embodiment, so the description is omitted.

[0112] The notification unit 30 presents the clinical evaluation scale on the display as input of information required for determining the pain level of the postoperative patient (ST21).

[0113] Such inquiry content can be constructed as a program so that it can be answered from the touch screen of the smart watch in terms of clinical comfort, comfort level, surgical recovery evaluation scale, etc. performed in the past clinical practice.

[0114] Examples of clinical evaluation scales include the four stages of "Pain" in "Evaluation of Urological Surgery after Postoperative Recovery Enhancement Protocol using the Quality of Recovery score QoR-40J (www.keiju.co.jp / manage / files / iryo / magazine_Vol.9_2021 / 2021_09_08miyagi.pdf)", namely "0: None", "1: Slight nausea", "2: Severe nausea", and "3: Vomiting".

[0115] As another example of a clinical evaluation scale, the comfort score includes four dimensions: physiological, psychological, spiritual, environmental, and social. The Kolcaba comfort status scale, which has a total of 35 items and is evaluated using Likert 4 levels, can be used. As another example of a clinical evaluation scale, indicators related to the surgical period can use pain, postoperative vomiting and nausea, recovery QOL (Quality of Life) scale, gastrointestinal recovery, exercise, sleep quality, etc. as comfort result indicators. The acquisition unit 20 can record a procedure that can notify the patient (user of the medical device) of the above-mentioned inquiry and answer through the touch screen.

[0116] The patient answers the above-mentioned inquiry by voice or screen (acquisition of biological information, ST22). In the case of answering by voice, the acquisition unit 20 operates the microphone, and the control unit 50 compares the acquired voice with the recorded voice data to determine the voice data considered to be the most recent. In addition, when the control unit 50 determines the text based on the patient's voice, it can determine the text based on the voice input by deep learning, etc. Such information processing can use well-known speech recognition technology. In the case where the answer to the inquiry is made through the touch screen, the control unit 50 detects the touch area of ​​the touch screen related to the notification unit 30 to determine the answer to the inquiry.

[0117] When the patient answers all the questions related to comfort, the results of each question are summarized, and the control unit 50 calculates the results for multiple scales (ST23). The answer to each question is composed of comfortable, normal, uncomfortable, etc. When the patient answers "yes" or "no" to comfortable 3, normal 2, and uncomfortable 1, a numerical value is assigned in a manner such as "yes" is 1 and "no" is 0. The answers to each question are summarized to calculate the total value (third score).

[0118] When the total value of the comfort level is greater than the seventh threshold value V7 (ST24: YES), the comfort level of the patient after surgery is above a certain level, and the intervention related to the comfort level is not changed, and the result is recorded in the acquisition unit 20 (ST25).

[0119] When the answer score to the comfort inquiry group becomes below the seventh threshold value V7 (ST24: No), the control unit 50 causes the acquisition unit 20 to record the answer and score to the inquiry, calculates the compression protocol in the same manner as the first embodiment, and adjusts the amount of decompression, frequency of decompression, etc. for each compression method.

[0120] If the score becomes below the seventh threshold value V7, it is unlikely that the patient's mental fatigue is higher than expected, so it is considered to adjust the compression decompression amount to be lower than the initial setting or to extend the frequency of decompression more than the initial setting. Corresponding to the score range for the comfort inquiry group, a table of compression time intervals and one-time decompression amount segmented changes is recorded in the acquisition unit 20, and the control unit 50 compares the actual total value of the patient with the above table to calculate the compression protocol and adjust the compression method (ST26).

[0121] in addition, Figure 6 The adjustment contents of the compression method shown in the flowchart of can be recorded in the acquisition unit 20 in the form of a program. The above-mentioned program can be recorded in the medical device in advance, or can be configured to be downloaded from the server 200 by the wearer.

[0122] In this modification, when the score calculated based on the patient's answer to the question about at least one of pain, vomiting, nausea, and physical condition of the patient who has undergone puncture surgery of an upper limb artery such as a radial artery exceeds the seventh threshold value V7, the control unit 50 adjusts the compression method. By configuring in this way, it is possible to control so that compression of the hemostatic site does not become a burden on the patient's mental (psychological) state, thereby improving the care of postoperative patients and preventing complications.

[0123] (Second embodiment)

[0124] Figure 7 This is a flowchart related to the adjustment of the compression method and the administration judgment of the anticoagulant determined by the medical system of the second embodiment. As shown by the peripheral temperature, the diameter of the medical device, etc. acquired by the acquisition unit in the first embodiment, the content of the judgment based on the different acquired information for the compression method and the administration judgment of the anticoagulant is explained. However, the adjustment of the compression method and the adjustment of the anticoagulant can also be judged based on the following information. It should be noted that the contents other than the adjustment of the compression protocol and the adjustment of the anticoagulant are the same as those of the first embodiment, so the common description is omitted.

[0125] First, the acquisition unit 20 acquires information (second information) related to anticoagulants and therapeutic drugs administered to the patient from the server 200 via the network N (acquisition of biological information, ST31). The information related to anticoagulants and therapeutic drugs can be recorded in the server 200 before the patient is discharged from a medical institution such as a hospital.

[0126] Next, the control unit 50 calculates the expected hemostasis time based on the information of the anticoagulant, the therapeutic drug, etc. (ST32). The expected hemostasis time can be determined by recording the corresponding data of the expected hemostasis time such as the dosage of the therapeutic drug or the anticoagulant, the anticoagulation time of various anticoagulants, and the blood vessel diameter from the server 200 to the acquisition unit 20, and comparing the data of the therapeutic drug, anticoagulant, blood vessel diameter, etc. used by the patient as the subject with the above data of the acquisition unit 20.

[0127] Next, the control unit 50 compares the expected hemostasis time calculated according to Formula 1 with the set fifth threshold value V5 to determine the size (ST33). For example, usually, heparin is administered at 100 units / kg / h before or during surgery, but in cases where the risk of stent thrombosis is high, multiple anticoagulants are administered. When anticoagulants are taken at a regular rate of 100 units / kg / h, bleeding can usually be stopped about 4 hours after surgery. On the other hand, when more than 100 units / kg / h are administered or multiple anticoagulants are administered, more than 4 hours of hemostasis are required. As a trend, the higher the efficacy of anticoagulants and therapeutic drugs, the longer the expected hemostasis time can be.

[0128] When the expected hemostasis time is equal to or less than the fifth threshold value V5 (ST33: NO), the control unit 50 determines that the patient's bleeding risk is low, and records information on the anticoagulant used in calculating the expected hemostasis time and information related to the expected hemostasis time in the acquisition unit 20 (ST34).

[0129] When the expected hemostasis time is greater than the fifth threshold value V5 (ST33: Yes), the control unit 50 determines that the bleeding risk is high (ST35), and causes the acquisition unit 20 to acquire the activated clotting time (ACT (Activated Clotting Time)) (acquisition of biological information, ST36). In addition, the control unit 50 calculates a score (second score) related to the risk of vascular occlusion based on the ACT (ST37). With respect to the occlusion rate (RAO (Radial Artery Occlusion)) of the radial artery with respect to the ACT, the RAO decreases as the ACT increases until the ACT reaches a specified value. If the specified value is exceeded, there is a tendency for the RAO to increase as the ACT increases. In the present embodiment, as an example, according to “The Activated Clotting Time Paradox” by Andrea Pacchioni et al. Figure 3, the RAO corresponding to ACT of 150 seconds and 250 seconds can be set as the fourth threshold. The RAO corresponding to ACT of 150 seconds and 250 seconds are the same value. If ACT is from 150 seconds to 250 seconds, RAO is less than the fourth threshold. If ACT is less than 150 seconds or more than 250 seconds, RAO may become more than the fourth threshold. The control unit 50 compares the RAO (score) corresponding to the acquired ACT with the fourth threshold.

[0130] When the score becomes lower than the fourth threshold value V4 (ST38: No), the control unit 50 determines that the patient's risk of vascular occlusion is low, and records the ACT and the calculated score in the acquisition unit 20 (ST39).

[0131] When the score becomes equal to or greater than the fourth threshold value V4 (ST38: YES), the control unit 50 determines that the patient has a high risk of vascular occlusion (ST40), calculates a hemostatic compression method protocol (ST41), and adjusts the compression method based on the compression protocol. The compression protocol derives at least one of the decompression amount and the decompression timing from the initial value, similarly to the first embodiment.

[0132] In addition, when the score becomes greater than the fourth threshold value V4, the control unit 50 prompts (notifies) the anticoagulant indication through the notification unit 30 (ST42). When the risk of vascular occlusion is high, the anticoagulant is set to a larger amount relative to the initial setting value. The amount of anticoagulant to be taken can be determined by pre-saving a database recording the relationship between the amount corresponding to the calculated score in the acquisition unit 20 and referring to the database. For example, the dosage of the anticoagulant can be divided into certain values ​​according to the score, and the dosage can be changed in stages by specifying the dosage according to the division.

[0133] in addition, Figure 7 The contents of the compression method adjustment and anticoagulant adjustment shown in the flowchart can be recorded in the acquisition unit 20 in the form of a program. The above program can be recorded in the medical device in advance, or can be configured to be downloaded from the server 200 by the wearer.

[0134] As described above, in this embodiment, the control unit 50 adjusts the compression protocol when the second score calculated based on the second information on anticoagulants, therapeutic drugs, etc. becomes equal to or greater than the fourth threshold value V4, and the notification unit 30 is configured to notify the method of taking anticoagulants, etc. By referring to the information on anticoagulants and therapeutic drugs used by the patient in this way, the state of the patient after surgery can be accurately predicted, and the patient's care can be carried out with high accuracy.

[0135] In addition, the second score related to the occlusion risk is calculated when the hemostasis time predicted based on the second information exceeds the fifth threshold value V5. By configuring in this way, it is possible to prevent or reduce the adjustment of the compression method and the adjustment of the anticoagulant without the intention of the medical practitioner, thereby improving the accuracy of postoperative patient care.

[0136] (Third embodiment)

[0137] Figure 8 This is a flowchart for judging the adjustment of the compression method and the adjustment of the anticoagulant in the third embodiment. In the second embodiment, the expected hemostasis time is calculated based on the information of the anticoagulant and therapeutic drug used by the patient, and the risk of vascular occlusion is calculated based on the ACT when the risk of bleeding is low, and the adjustment of the compression method and the adjustment of the anticoagulant are judged. However, the adjustment of the compression method and the adjustment of the anticoagulant can also be judged as follows.

[0138] Since the limbs swell due to blood seepage, in this embodiment, the circumference of the puncture site (the circumference around the arm including the puncture site) is measured to determine the state of edema, and the adjustment of medication and the adjustment of the compression method are determined. The acquisition unit 20 acquires the circumference information of the site where the medical device is installed (acquisition of biological information, ST51). Next, the control unit 50 compares the difference between the circumference of the installation part 60 (puncture site) of the medical device obtained and the reference value with the sixth threshold value V6 (ST52).

[0139] When the difference with the benchmark becomes below the sixth threshold value V6 (measured value < benchmark value) (ST52: No), the control unit 50 determines that no intervention related to the hematoma is required, and records the information related to the circumference and the difference in the acquisition unit 20, and does not perform any intervention related to the hematoma (ST53).

[0140] When the difference from the benchmark exceeds the sixth threshold value V6 ((measured value> benchmark value), ST52: Yes), the control unit 50 determines that intervention related to the hematoma is required (ST54), and adjusts the dosage of the anticoagulant as in the first embodiment and notifies the notification unit 30 (ST55). The anticoagulant can be adjusted to inhibit blood exudation. For example, in the case of a patient taking a diuretic due to edema, the amount of the diuretic is adjusted. The dosage of the anticoagulant is set so that the difference from the benchmark is divided into certain amounts, and the dosage of the anticoagulant can be increased in stages as the difference moves away from the benchmark.

[0141] In addition, when the difference from the reference exceeds the sixth threshold value V6 (ST52: YES), the control unit 50 determines that the compression method needs to be adjusted, calculates the compression protocol (ST56), and adjusts the compression method based on the compression protocol. The compression protocol can specify the decompression timing from the initial value and the decompression amount at each decompression timing, similarly to the first embodiment.

[0142] in addition, Figure 8 The contents of the adjustment of the compression method and the adjustment of the anticoagulant shown in the flowchart can be recorded in the form of a program by the acquisition unit 20. The above program can be recorded in the medical device in advance, or can be configured to be downloaded from the server 200 by the wearer.

[0143] As described above, in this embodiment, the circumference of the site where the medical device is installed is measured, and when the difference between the obtained circumference and the reference exceeds the sixth threshold value V6, the adjustment of the anticoagulant and the compression method are adjusted. The circumference of the puncture site can be increased or decreased according to the state of the hemostatic site of the postoperative patient, so the anticoagulant or the compression method can be adjusted based on this information to more accurately reflect the postoperative patient's condition, and postoperative care can be implemented with higher accuracy.

[0144] It should be noted that the present invention is not limited to the above-mentioned embodiments, and various changes can be made in the claims. In the first embodiment, it is described that the mounting portion 60 adjusts the amount of compression of the compression portion by filling and releasing a fluid such as air. However, if the amount of compression of the mounting portion can be adjusted, the structure of the mounting portion is not limited to the above-mentioned pump, etc., and the motor can be connected to the belt of the winding portion 62, and the circumference can be increased or decreased by winding the belt in accordance with the rotation of the motor, thereby adjusting the amount of compression. In the case of using a belt to adjust the compression force of the hemostatic portion, the circumference of the mounting portion of the belt is increased by the rotation of the motor, thereby reducing the compression force, and the compression force can be increased by shortening the circumference of the mounting portion.

[0145] In addition, in the first modification of the first embodiment, it is described that the answer to the inquiry related to the comfort level is performed through the touch screen of the acquisition unit 20 of the medical device 100 or voice input. However, the answer to the inquiry is not limited to the above-mentioned medical device. The answer to the inquiry related to the comfort level can also be answered from the smartphone, etc., based on the installation of a program for answering the inquiry related to the comfort level on a smartphone, a tablet-type communication terminal, or a PC, etc. (hereinafter referred to as a smartphone, etc.).

[0146] In addition, in the first embodiment, it is described that the notification unit 30 notifies the user of the salt deficiency and the amount of drinking water in accordance with the detection result of the sensor, but the notification of the salt deficiency and the amount of drinking water may not be performed. In addition, the notification of the salt deficiency and the amount of drinking water may also be performed in the first modification of the first embodiment, the second embodiment, and the third embodiment.

[0147] In the first embodiment, when the risk of internal bleeding is high, the family members are notified, but the family members may not be notified. In the second embodiment, when the risk of bleeding is determined to be high, the family members may be notified as in the first embodiment.

[0148] In addition, the medical device 100 is described as setting which sensor among the sensors described in the acquisition unit 20 can be made to perform the measurement function when the patient is discharged. However, the sensor mounted on the medical device as the acquisition unit may be configured to be different for each patient.

[0149] (Fourth embodiment)

[0150] Fig. 9 : is a diagram showing the appearance of the medical system of the fourth embodiment. The first mounting portion 60a is a disposable (single use) tourniquet that is fixed and can be installed in a state of being wound around the patient's wrist or forearm. A hemostatic balloon is arranged on the inner side of the first mounting portion 60a. The hemostatic balloon is connected to the balloon side tube T1, and air can be injected into the hemostatic balloon through the inner cavity of the balloon side tube T1. A tourniquet connector C1 that can be connected to a syringe for injecting air is provided at the end of the balloon side tube T1, and a valve that is opened only when the syringe is connected is provided in the connector, and air does not circulate when it is not connected. When air is injected into the hemostatic balloon with the first mounting portion 60a mounted on the patient's wrist, the puncture portion such as a needle is compressed by the hemostatic balloon inflated by the air, and bleeding from the puncture portion can be suppressed.

[0151] The second mounting portion 60b (equivalent to the mounting portion) constituting the medical device 100b is also fixed and mountable in a state of being wrapped around the patient's wrist or forearm. The second mounting portion 60b is mounted on the same hand as the first mounting portion 60a. If possible, it is desirable that the second mounting portion 60b is disposed on the distal side of the first mounting portion 60a and senses the state of the artery downstream, but is not limited thereto. The second mounting portion 60b is provided with an acquisition portion 20, a solenoid valve (valve), a control portion 50, a power supply portion 10, an air pump, and a second mounting portion side tube T2. The acquisition portion 20 has an oxygen saturation sensor and an air pressure sensor. The oxygen saturation sensor can measure the oxygen saturation of blood flowing in the radial artery of the patient's forearm. A connector C2 that can be connected to the tourniquet connector C1 of the balloon side tube T1 is provided at the front end of the second mounting portion side tube T2. The connector C2 can open the valve in the tourniquet connector when connected in the same manner as a syringe. In this state, when the air pump is driven, the balloon of the tourniquet can be filled with air. A solenoid valve is connected to the base end of the second mounting portion side tube T2. The hemostatic balloon is filled with air, and when the opening and closing portion of the solenoid valve is operated by the actuator to open the solenoid valve while the hemostatic balloon side tube is connected to the second mounting portion side tube T2, air is discharged from the hemostatic balloon to reduce pressure. The amount of pressure reduction can be adjusted by adjusting the time for which the solenoid valve is opened. The air pressure sensor can measure the air pressure in the second mounting portion side tube. The control unit 50 can adjust the amount of pressure reduction based on the measured air pressure and the time elapsed from the start of compression of the hemostatic balloon. The control unit 50 can also control the opening and closing of the solenoid valve based on a predetermined compression protocol.

[0152] When the radial artery is compressed by the hemostatic balloon for a long time, the radial artery may be blocked. When the oxygen saturation measured by the oxygen saturation sensor is lower than the predetermined time reference value, the control unit determines that there is a risk of radial artery blockage, and can open the solenoid valve to discharge air to reduce pressure, and can control to reduce compression.

[0153] The first mounting part 60a and the second mounting part 60b can be separated by disconnecting the balloon side tube T1 and the second mounting part side tube T2. After treatment, a large amount of patient blood may be attached to the first mounting part 60a. Therefore, the first mounting part 60a cannot be reused or is difficult to reuse. However, the second mounting part 60b having expensive components such as the control part 50, the acquisition part 20, the electromagnetic valve, and the power supply part 10 is separated from the first mounting part 60a, thereby being reused after sterilization.

[0154] According to the present embodiment, since the first mounting portion 60a and the second mounting portion 60b are separable, there is an effect that the second mounting portion 60b provided with expensive components can be reused.

[0155] This application is based on Japanese Patent Application No. 2022-088683 filed on May 31, 2022, the disclosed contents of which are incorporated herein by reference in their entirety.
