Description

[Technical Field]

[0001] The present invention relates to an intraoperative patient management system that manages the risk of developing bedsores during or after surgery. [Background technology]

[0002] During surgery, patients are generally placed on the operating table under general anesthesia and remain in the same position, which can lead to problems such as bedsores (pressure sores) during or after surgery. These bedsores develop when concentrated pressure is applied to specific areas of the patient's body surface for a long period of time, or when frictional forces (shear forces) are applied to specific areas of the patient's body surface. These frictional forces occur when the skin on specific areas of the body is dragged when the patient is moved on the table.

[0003] To prevent the development of bedsores, it is generally recommended that the patient's position be changed regularly (for example, every two hours) and that friction (shear force) on the skin be minimized when moving the patient.As such, there are currently no specific indicators (standards) for medical professionals to use during surgery to reduce the risk of developing bedsores in patients, and medical professionals can only address the risk of developing bedsores by appropriately adjusting the patient's position (posture) before and during surgery, which means they have to rely on their experience and intuition.

[0004] For example, Patent Document 1 discloses an operating table operating device that allows a user to operate the movement of a table of a robotic operating table, which moves a table for placing a patient using a multi-joint robot arm, and that includes an instruction receiving unit that receives an instruction from the user to move the table, and a display unit that is configured to display the elapsed time in an inclined position when the table is placed in an inclined position by the multi-joint robot arm in response to the movement instruction.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-209191 Summary of the Invention [Problem to be solved by the invention]

[0006] The operating table operating device described in Patent Document 1 mentioned above allows the medical staff operating the operating device to take care to ensure that the patient placed on the table is not maintained in the same tilted position for a long period of time, thereby preventing the onset and worsening of bedsores (bed sores) in the patient even when the table is tilted to tilt the patient.

[0007] However, with the operating table operating device described in Patent Document 1, even if medical personnel can take care to ensure that the patient is not maintained in a tilted position for a long period of time, it is unclear to what extent the patient's risk of developing a bedsore is increased, and it is difficult to reduce the patient's risk of developing a bedsore by alerting medical personnel to the increased risk of developing a bedsore in a specific part of the patient and dispersing the pressure applied to that specific part by changing the patient's position or increasing the amount of cushioning material.

[0008] The present invention has been made in consideration of the above points, and aims to provide an intraoperative patient management system that can inform medical personnel of the degree of risk of a patient developing a bedsore during surgery and alert them to the risk. [Means for solving the problem]

[0009] As a means for solving the above problem, the invention described in claim 1 is an intraoperative patient management system for managing the risk of bedsore development in a patient during surgery, and is configured to display the result of integrating the body pressure distribution on the patient over time during surgery on a bedsore development risk display unit. During surgery, the position of the operating table on which the patient is placed is always displayed and recorded on the pressure ulcer risk display unit. It is characterized by the following.

[0010] Conventionally, academic conferences and other forums have proposed detecting the pressure distribution on a patient's body surface in real time during surgery (hereinafter referred to as "body pressure distribution on the patient") to prevent the development of bedsores. However, as mentioned above, bedsores develop when pressure is concentrated on a specific part of the patient's body surface for a long period of time, so detecting the body pressure distribution on the patient in real time during surgery is not very useful. Furthermore, in this proposal, the body pressure distribution on the patient changes in real time during surgery due to factors such as changes in the strength of the surgical approach to the patient by the surgeon and assistant, changes in the position (posture) of the operating table, and changes in the patient's position (posture). Therefore, even if medical professionals check this body pressure distribution on the patient detected in real time, it is not easy to accurately determine whether the patient is at increased risk of developing a bedsore.

[0011] In view of this, in the invention of claim 1, the body pressure distribution on the patient, detected at regular time intervals during surgery, for example, by a body pressure distribution detection sheet material, is integrated over time and the integrated body pressure distribution map is displayed on a pressure ulcer development risk display unit installed in the operating room, so that medical staff can visually check this integrated body pressure distribution map on the patient and accurately determine whether or not there is an increased risk of pressure ulcer development in a specific part of the patient.If the medical staff determines that there is an increased risk of pressure ulcer development, they can take appropriate measures to distribute the body pressure on the patient, such as changing the position of the operating table or the patient's position, or increasing the amount of cushioning material around that specific part. Furthermore, in the invention of claim 1, the position of the operating table is always displayed on the pressure ulcer risk display unit, so for example, after a medical professional determines that the risk of developing a pressure ulcer is increasing based on the accumulated body pressure value on a specific part of the patient, they can quickly change the position of the operating table while understanding the current position of the operating table. Also, by recording and accumulating the position of the operating table along with the accumulated results of the body pressure distribution on the patient over time during surgery, the position of the operating table can be included when analyzing the accumulated data, and the risk of developing a pressure ulcer on a specific part of the patient relative to the table position can be analyzed, allowing for a wider range of analysis results.

[0012] The invention described in claim 2 is characterized in that in the invention described in claim 1, the results of integrating the body pressure distribution on the patient over time during the surgery are recorded.

[0013] In the invention of claim 2, for each surgery, personal data including the surgical procedure, for example, physical information such as gender, age, weight, and height, and the presence or absence of underlying diseases and medical history, is input in advance, and the body pressure distribution on the patient during surgery is recorded and accumulated along with the results accumulated over time, making it possible to analyze the tendency of the risk of bedsore development based on the accumulated data. Then, based on the analysis results, the accumulated body pressure value at which the risk of bedsore development increases can be set as a threshold for each surgery, and during surgery, the threshold can be displayed on the bedsore development risk display unit, or an alarm can be sounded if the threshold is exceeded, to alert medical personnel.

[0014] The invention described in claim 3 is characterized in that, in the invention of claim 1, the pressure ulcer development risk display unit also displays the results of real-time detection of the body pressure distribution on the patient during surgery.

[0015] In the invention of claim 3, the results of real-time detection of the body pressure distribution on the patient during surgery, i.e., the body pressure distribution on the patient detected at regular time intervals, for example, by a body pressure distribution detection sheet material (a real-time body pressure distribution map on the patient at that time), are also displayed.Therefore, for example, after a medical professional determines that the risk of developing a bedsore is increasing based on the accumulated body pressure value on a specific part of the patient, they can take measures such as changing the position of the operating table or the patient's position, or increasing the amount of cushioning material around that specific part, and then quickly check whether the body pressure on the patient is being distributed. [Effects of the Invention]

[0018] According to the intraoperative patient management system of the present invention, it is possible to inform medical personnel of the degree of risk of the patient developing a bedsore during surgery and to alert them. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. An intraoperative patient management system 1 according to an embodiment of the present invention manages the risk of a patient developing a bedsore during surgery and alerts medical personnel. The medical personnel are the staff present in the operating room involved in the surgery, including multiple surgeons (such as the surgeon and assistants), an anesthesiologist, and multiple nurses. Referring to FIG. 1 , the intraoperative patient management system 1 according to this embodiment includes a table position detection unit 3 that detects the position (posture) of a table 12 on an operating table 10 over time during surgery; a body pressure distribution detection sheet 4 that detects the body pressure distribution on the patient on the table 12 at regular intervals during surgery; a bedsore risk acquisition unit 5 that acquires the patient's risk of developing a bedsore based on the body pressure distribution on the patient detected by the body pressure distribution detection sheet 4; and a bedsore risk display unit 6 that displays the information acquired by the bedsore risk acquisition unit 5.

[0021] Referring to Figure 2, the operating table 10 has the function of freely changing the position of the table 12 on which the patient rests and fixing it at any position. The operating table 10 generally comprises the table 12 on which the patient rests, a support 13 supporting the table 12, and a base 15 with casters 14 at its four corners. The longitudinal direction of the table 12 corresponds to the patient's head-to-tail direction, and its width direction corresponds to the patient's left-to-right direction. The table 12 is unitized by connecting, for example, a back-side table portion 17, a center table portion 18, and a leg-side table portion 19, which are arranged along the longitudinal direction. A plurality of mattresses 21, 21 of a predetermined thickness are detachably attached to the table 12.

[0022] 2 and 3, the table 12 of the operating table 10 can be adjusted and fixed at any position by a medical professional operating an operating table control panel 22 (described later). That is, the table 12 is configured so that it can be raised and lowered as a whole, can slide along its longitudinal direction (head-to-tail direction of the patient) and its width direction (left-to-right direction of the patient), and can be fixed at any position. The table 12 is also configured so that it can be rotated (also called vertically rotatable) around the upper end of the support column 16 in a side view, and can be rotated (also called horizontally rotatable) around the upper end of the support column 16 in a front view, and can be fixed at any position. Furthermore, the table 12 is configured so that the back-side table portion 17, the center table portion 18, and the leg-side table portion 19 can be independently rotated relative to the horizontal plane (the floor of the operating room) in a side view, and can be fixed at any position. In some cases, the leg-side table portion 19 is divided into two parts along the width direction, each of which is rotatable relative to the horizontal plane and can be fixed at any position.

[0023] An operating table control panel 22, which is operated by a medical professional when changing the position of the table 12, is electrically connected to the operating table 10. The operating table control panel 22 is electrically connected via communication means (not shown) to a control unit (not shown) that controls the drive of multiple cylinder devices and the like provided on the operating table 10. The operating table control panel 22 has multiple operation buttons 25 and a display screen 26 on its front surface. By pressing the operation buttons 25 on the operating table control panel 22, the medical professional can appropriately change the position (posture) of the table 12. The display screen 26 of the operating table control panel 22 displays position information and the like of the table 12 of the operating table 10 in real time.

[0024] 2 and 3, the operating table control panel 22 incorporates a table position detection unit 3 that detects the position of the table 12 over time. The table position detection unit 3 detects the position of the table 12 over time based on the operation history of the multiple operation buttons 25, the drive history of multiple cylinder devices and the like within the operating table 10, and detection information obtained from various sensors such as encoders within the operating table 10. In this embodiment, the position of the table 12 refers to the position after operations of the table 12, including lifting, sliding, vertical rotation, and horizontal rotation. As shown in FIG. 1, the table position detection unit 3 is electrically connected to a pressure ulcer development risk acquisition unit 5, which will be described later.

[0025] 1 and 2, the body pressure distribution detection sheet material 4 can detect and visualize the body pressure on the patient on the table 12, i.e., the body pressure distribution (pressure distribution) on the patient. The body pressure distribution detection sheet material 4 can detect the body pressure distribution on the patient at regular time intervals. In this embodiment, the body pressure distribution detection sheet material 4 detects the body pressure distribution on the patient at one-second intervals. The time interval for detection by the body pressure distribution detection sheet material 4 can be changed as appropriate. The body pressure distribution detection sheet material 4 is, for example, composed of two half-body sheet materials. Note that a full-body sheet may also be used. The body pressure distribution detection sheet material 4 is composed of a material that is transparent to X-rays. The body pressure distribution detection sheet material 4 is composed of a so-called silver-free material that is transparent to X-rays. The body pressure distribution detection sheet material 4 is detachably attached to the mattress 21 on the table 12 of the operating table 10. The body pressure distribution detection sheet material 4 is electrically connected to the pressure ulcer development risk acquisition unit 5.

[0026] Referring to FIG. 1, the pressure ulcer development risk acquisition unit 5 includes an accumulating unit 30 and a recording unit 31. The accumulating unit 30 accumulates the body pressure distribution from the body pressure distribution detection sheet 4, i.e., the body pressure distribution of the patient detected at regular time intervals by the body pressure distribution detection sheet 4, over time. The recording unit 31 records and accumulates, for each surgery, table position information obtained from the table position detection unit 3, the real-time body pressure distribution, which is the body pressure distribution of the patient detected at regular time intervals by the body pressure distribution detection sheet 4, and the accumulated body pressure distribution of the patient obtained by the accumulating unit 30. In addition, for each surgery, physical information such as the surgical procedure, gender, age, weight, and height (BMI), and personal data such as the presence or absence of underlying diseases and medical history are input into the recording unit 31 in advance.

[0027] The pressure ulcer development risk display unit 6 is placed in an operating room (not shown). The pressure ulcer development risk display unit 6 is configured as a so-called monitor. Although not shown, the pressure ulcer development risk display unit 6 may be placed near the anesthesia equipment in the operating room, or may be placed so as to be suspended from the operating table 10 together with a shadowless lamp or the like. There are no limitations on the location of the display unit as long as it is easily visible to medical personnel. In this embodiment, the pressure ulcer development risk display unit 6 is placed in the operating room, but it may also be placed in other locations besides the operating room, such as a doctor's waiting room, a nurse's station, or an educational facility. The pressure ulcer development risk display unit 6 is electrically connected to the pressure ulcer development risk acquisition unit 5. Referring to Figure 4, the pressure ulcer development risk display unit 6 simultaneously displays information from the pressure ulcer development risk acquisition unit 5 during surgery, namely, a real-time body pressure distribution diagram (left side of Figure 4) which is the body pressure distribution on the patient detected at regular time intervals (body pressure distribution on the patient at that time), an integrated body pressure distribution diagram (center of the left and right of Figure 4) which is the accumulation of the body pressure distribution on the patient detected at regular time intervals, and table position information of the operating table 10 at that time (right side of Figure 4).

[0028] Furthermore, referring to FIG. 4, the pressure ulcer risk display unit 6 can simultaneously display information from the recording unit 31 of the pressure ulcer risk acquisition unit 5 after surgery, i.e., a real-time body pressure distribution map (left side of FIG. 6) showing the body pressure distribution of the patient detected at regular time intervals for each surgery, an integrated body pressure distribution map (center of FIG. 6) showing the integrated body pressure distribution of the patient detected at regular time intervals, and table position information of the operating table 10 over time (right side of FIG. 6). The real-time body pressure distribution map is displayed two-dimensionally, with body pressure levels indicated by color. As body pressure increases, the display changes from blue to green to yellow to red (note that because colors cannot be displayed in FIGS. 4 and 6, body pressure increases as the color changes from white to black). In other words, the real-time body pressure distribution map indicates that specific areas displayed in red (the darkest black in the figure) have high body pressure.

[0029] The accumulated pressure distribution map is displayed as a three-dimensional bar graph. The accumulated pressure distribution map displayed on the pressure ulcer risk display unit 6 in Figure 5 is an example of the accumulated pressure distribution map recorded in the recording unit 31 of the pressure ulcer risk acquisition unit 5 over time after surgery. Specifically, Figure 5(a) shows the accumulated pressure distribution map one hour after the start of surgery, Figure 5(b) shows the accumulated pressure distribution map two hours after the start of surgery, Figure 5(c) shows the accumulated pressure distribution map three hours after the start of surgery, and Figure 5(d) shows the accumulated pressure distribution map four hours after the start of surgery. During surgery, the accumulated pressure distribution map displayed on the pressure ulcer risk display unit 6 displays the threshold accumulated pressure value at which the patient's risk of developing a pressure ulcer increases. When this threshold is exceeded, medical personnel can determine that the risk of developing a pressure ulcer is increasing for a particular part of the patient.

[0030] 5, it can be seen that the integrated body pressure values ​​at two parts of the patient increase over time and exceed the threshold. Medical professionals can grasp to some extent the relative position of each part of the patient with respect to the body pressure distribution detection sheet 4, that is, the relative position of each part of the patient with respect to any position of the body pressure distribution detection sheet 4 (any position on the integrated body pressure distribution map), and therefore can, by checking the integrated body pressure distribution map, identify to some extent the parts of the patient that are at increased risk of developing bedsores.

[0031] The table position information of the operating table 10 displayed on the pressure ulcer development risk display unit 6 shown in Figure 4 is displayed, for example, from the top, as the vertical rotation angle of the operating table 10, the horizontal rotation angle of the operating table 10, the back board flexion angle of the operating table 10, the amount of elevation change of the operating table 10, the amount of sliding (longitudinal direction) of the operating table 10, the left leg board flexion angle of the operating table 10, and the right leg flexion angle of the operating table 10. Furthermore, with reference to Figure 5, the pressure ulcer development risk display unit 6 can simultaneously display an integrated body pressure distribution diagram (right side of Figure 5) and table position information of the operating table 10, such as the vertical rotation angle, horizontal rotation angle, back board flexion angle, amount of sliding change, amount of elevation change, left leg board flexion angle, right leg board flexion angle, etc. (left side of Figure 5) during and after surgery.

[0032] 6, the pressure ulcer development risk display unit 6 can simultaneously display a real-time body pressure distribution map (right side of FIG. 6) and table position information of the operating table 10, such as the vertical rotation angle, horizontal rotation angle, back board flexion angle, slide amount, elevation amount, left leg board flexion angle, right leg board flexion angle, etc. (left side of FIG. 6) during and after surgery. Furthermore, although not shown, the pressure ulcer development risk display unit 6 can also independently display a real-time body pressure distribution map and an integrated body pressure distribution map during and after surgery.

[0033] Next, the operation of the intraoperative patient management system 1 according to this embodiment will be described. In the intraoperative patient management system 1 according to this embodiment, personal data (described above) of the patient undergoing surgery, including the surgical procedure to be adopted, is input to the recording unit 31 of the pressure ulcer development risk acquisition unit 5 before surgery. Next, the patient is placed on the body pressure distribution detection sheet 4 of the operating table 10, and a medical professional operates the various operation buttons 25 of the operating table control panel 22 to move the table 12 and position the patient as desired. From this point on, the table position detection unit 3 detects the position of the table 12 over time, and the table position information is recorded in the recording unit 31 of the pressure ulcer development risk acquisition unit 5 and displayed on the pressure ulcer development risk display unit 6. When the patient is placed on the body pressure distribution detection sheet 4 of the operating table 10 and positioned as desired, cushions or the like are appropriately inserted between the body pressure distribution detection sheet 4 and the patient's body in positions where the risk of developing a pressure ulcer is expected to be high.

[0034] At approximately the same time, the body pressure on the patient is detected at regular time intervals by the body pressure distribution detection sheet 4, and the body pressure information is input to the accumulator 30 and recorder 31 of the pressure ulcer development risk acquisition unit 5. Then, the surgery begins, and the accumulator 30 of the pressure ulcer development risk acquisition unit 5 accumulates the body pressure distribution from the body pressure distribution detection sheet 4, i.e., the body pressure distribution on the patient detected at regular time intervals by the body pressure distribution detection sheet 4, over time. The pressure ulcer development risk display unit 6 also displays a real-time body pressure distribution map, which is the body pressure distribution on the patient detected at regular time intervals (the body pressure distribution on the patient at that time), an accumulated body pressure distribution map, which is the accumulation of the body pressure distribution on the patient detected at regular time intervals, and the table position information of the operating table 10 at that time. During surgery, the medical staff can select the display content of the pressure ulcer development risk display unit 6 from the multiple display contents described above by switching operation. For example, when "Cumulative Display" in the pressure ulcer development risk display unit 6 shown in Figure 6 is clicked, the display content of the pressure ulcer development risk display unit 6 switches from a real-time body pressure distribution diagram to an accumulated body pressure distribution diagram. In addition, the recording unit 31 of the pressure ulcer development risk acquisition unit 5 records the table position information of the operating table 10, the real-time body pressure distribution, and the accumulated body pressure distribution over time during the surgery.

[0035] During surgery, the medical professional checks the integrated body pressure distribution map displayed on the pressure ulcer risk display unit 6 and determines that a particular part of the patient is at increased risk of developing a pressure ulcer when the integrated body pressure value on the patient exceeds a pre-displayed integrated body pressure threshold at which the risk of developing a pressure ulcer increases. Next, as described above, the medical professional checks the integrated body pressure distribution map and can determine to some extent which part of the patient's body is at the point where the integrated body pressure value on the patient exceeds the threshold. Then, as described above, the medical professional takes appropriate measures to redistribute the patient's body pressure, such as changing the position of the table 12 on the operating table 10 or the patient's position, or increasing the amount of cushioning around the affected area. The medical professional then checks the real-time body pressure distribution map displayed on the pressure ulcer risk display unit 6 to determine whether the measures taken are appropriate.

[0036] Furthermore, the risk of developing a pressure ulcer can be analyzed in detail based on the table position information of the operating table 10 over time, the real-time body pressure distribution and integrated body pressure distribution over time, personal data, and the degree of the patient's postoperative pressure ulcer (including redness) recorded and accumulated in the recording unit 31 of the pressure ulcer development risk acquisition unit 5. Based on the analysis results, the integrated body pressure value at which the risk of developing a pressure ulcer increases can be accurately set as a threshold, particularly for each surgery. In addition to obtaining the threshold integrated body pressure value at which the risk of developing a pressure ulcer increases, the analysis can also analyze the causal relationship of developing a pressure ulcer, such as the correlation between the patient's physical characteristics, including special surgical procedures (positions), and the integrated body pressure distribution, or the correlation between special table positions and the integrated body pressure distribution.

[0037] The intraoperative patient management system 1 according to this embodiment, as described above, particularly comprises a body pressure distribution detection sheet 4 that detects the body pressure on the patient on the table 12 during surgery at regular time intervals, a pressure ulcer development risk acquisition unit 5 that acquires the degree of risk of the patient developing a pressure ulcer based on the body pressure information from the body pressure distribution detection sheet 4, and a pressure ulcer development risk display unit 6 that displays the information acquired by the pressure ulcer development risk acquisition unit 5. Furthermore, an accumulator 30 in the pressure ulcer development risk acquisition unit 5 accumulates the body pressure distribution on the patient detected at regular time intervals by the body pressure distribution detection sheet 4 over time, and the accumulated body pressure distribution diagram is displayed on the pressure ulcer development risk display unit 6.

[0038] As a result, by visually checking the integrated body pressure distribution map displayed on the pressure ulcer development risk display unit 6, a medical professional can confirm the degree of risk of developing a pressure ulcer in a specific part of the patient, and as a result, can alert the patient to the increased risk of developing the pressure ulcer. In other words, by visually checking the integrated body pressure distribution map displayed on the pressure ulcer development risk display unit 6, a medical professional can accurately determine whether or not the risk of developing a pressure ulcer in a specific part of the patient is increasing.

[0039] If a medical professional determines that the accumulated body pressure value on the patient has exceeded the threshold value and that the risk of developing a bedsore is increasing, appropriate measures can be taken to distribute the body pressure on the patient, such as changing the position of the table 12 of the operating table 10 or the patient's position, or increasing the amount of cushioning material around the specific area. In short, the intraoperative patient management system 1 according to this embodiment aims to alert medical professionals that the accumulated body pressure value on the patient has exceeded the threshold value during surgery and that the risk of developing a bedsore is increasing, and to distribute the accumulated body pressure values ​​in all parts of the patient (regardless of the area) so that they are lower than the threshold value through appropriate measures by the medical professional.

[0040] Furthermore, in the intraoperative patient management system 1 according to this embodiment, the accumulator 30 of the pressure ulcer development risk acquisition unit 5 accumulates the patient's body pressure distribution, detected at regular intervals by the body pressure distribution detection sheet 4, over time, and records and accumulates this accumulated body pressure distribution in the recorder 31 of the pressure ulcer development risk acquisition unit 5. This allows for an analysis of the risk of developing a pressure ulcer based on the recorded and accumulated accumulated body pressure distribution data and personal data, etc. Then, based on the analysis results, a threshold value is set for the accumulated body pressure for each surgery at which the risk of developing a pressure ulcer increases, and this threshold value is displayed on the pressure ulcer development risk display unit 6, making it possible to easily communicate the risk of developing a pressure ulcer to medical personnel and draw their attention to it.

[0041] Furthermore, in the intraoperative patient management system 1 according to this embodiment, during surgery, the pressure ulcer development risk display unit 6 also displays the results of real-time detection of the body pressure distribution on the patient, i.e., a real-time body pressure distribution map showing the body pressure distribution on the patient (the body pressure distribution on the patient at that time) detected at regular time intervals by the body pressure distribution detection sheet material 4. This allows medical personnel to determine that the risk of developing a pressure ulcer is increasing based on the integrated body pressure value accumulated on a specific part of the patient, and then take measures such as changing the position of the table 12 of the operating table 10 or the patient's position, or increasing the amount of cushioning around that specific part, and then quickly check using the real-time body pressure distribution map whether the body pressure on the patient is being distributed properly.

[0042] Furthermore, since the position of the table 12 of the operating table 10 during surgery is constantly displayed on the pressure ulcer development risk display unit 6 and recorded in the recording unit 31 of the pressure ulcer development risk acquisition unit 5, for example, after a medical professional determines that the patient is at increased risk of developing a pressure ulcer, the medical professional can quickly change the position of the table 12 of the operating table 10 while understanding the current position of the table 12. Furthermore, by recording and accumulating the position of the table 12 of the operating table 10, the position of the table 12 of the operating table 10 can also be included when analyzing the accumulated data, and the risk of the patient developing a pressure ulcer depending on the position of the table 12 can also be analyzed, allowing for a wider range of analysis results.
