Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a method and computer equipment for analyzing the covering degree of a chest circumferential contraction bandage. Background Art

[0002] Chest compression is an important part of CPR (Cardiopulmonary Resuscitation). Effective compression helps to generate forward blood flow, supply oxygen to the heart, brain and other important organs, and replenish myocardial ATP reserves, which is critical for successful defibrillation and resuscitation. Single-point chest compression has an irreversible inefficiency. Even high-quality compression can only provide 10%-30% and 30%-40% of the blood perfusion before arrest to the heart and brain, respectively. The generation of forward blood flow is mainly determined by the increase in intrathoracic pressure (thoracic pump mechanism), and direct cardiac compression (heart pump mechanism) plays only a small role in it.

[0003] The original intention of designing a cardiopulmonary resuscitation machine (or chest compression machine) is to increase the blood flow to the heart and brain of patients with cardiac arrest, and at the same time to serve as a bridge to more specific treatment methods including defibrillation, intravenous medication, cardiac catheterization technology and other forms of vascular reconstruction therapy. Some cardiopulmonary resuscitation machines in the prior art increase the forward blood flow by adding a bandage wrapped around the chest (i.e., a chest contraction bandage) on the basis of directly pressing the sternum, thereby driving the effect of chest contraction and generating a higher positive pressure in the chest cavity, such as the technical solutions recorded in the applicant's previous patents CN115944521A and CN116785151A.

[0004] The applicant's research shows that when the chest compression machine is installed on the patient, the degree of coverage of the patient's chest by the chest compression bandage is one of the factors affecting blood perfusion during cardiopulmonary resuscitation. However, there is currently no effective means to automatically detect and determine the degree of coverage of the patient's chest by the chest compression bandage during cardiopulmonary resuscitation. Summary of the invention

[0005] Based on this, it is necessary to provide a method and computer equipment for analyzing the coverage of a circumferential chest compression bandage to address the problem of being unable to determine whether the bandage covers the patient appropriately.

[0006] A method for analyzing the coverage degree of a circumferential chest contraction bandage comprises obtaining sensing information of the bandage; and determining the coverage information of the bandage for a patient according to the sensing information.

[0007] In one embodiment, the sensing information includes shape information, contact information and position information corresponding to the contact information, the covering information includes tension level, and determining the covering information of the bandage for the patient based on the sensing information includes determining a covering contour graphic of the bandage based on the shape information; determining a covering demarcation point position on the covering contour graphic based on the contact information and the position information; determining a contact area and a non-contact area on the covering contour graphic based on the covering demarcation point position; and determining the tension level of the bandage based on the shape information of the non-contact area.

[0008] In one embodiment, determining the tension of the bandage based on the shape information of the non-contact area includes analyzing the line shape of the non-contact area; determining that the bandage is not tensioned in response to a judgment that the line shape of the non-contact area is a curve; and determining that the bandage is tensioned in response to a judgment that the line shape of the non-contact area is a straight line.

[0009] In one embodiment, the covering contour graphic includes two covering demarcation point positions, and the covering information includes a covering degree. After determining the covering demarcation point positions on the covering contour graphic according to the contact information and the position information, the method further includes analyzing the covering contour graphic to determine the widest distance of the covering contour graphic in a transverse direction; determining a demarcation point spacing distance between two covering demarcation point positions in the transverse direction; and determining a covering degree of the bandage for the patient according to a ratio of the demarcation point spacing distance to the widest distance.

[0010] In one embodiment, determining the degree of coverage of the bandage for the patient based on the distance ratio of the demarcation point interval to the widest distance includes judging whether the distance ratio is in an optimal ratio interval; in response to the judgment result that the distance ratio is in the optimal ratio interval, determining that the coverage of the bandage is qualified; in response to the judgment result that the distance ratio is not in the optimal ratio interval, determining that the coverage of the bandage is unqualified.

[0011] In one embodiment, the sensing information includes pressure information and position information corresponding to the pressure information, and the covering information includes covering strength. After determining the covering demarcation point position on the covering contour graphic according to the contact information and the position information, the method further includes determining a force analysis area on the covering contour graphic according to the covering demarcation point position; determining a contact pressure value according to the force analysis area, the pressure information and the position information; and determining the covering strength of the bandage on the patient according to the contact pressure value.

[0012] In one embodiment, determining the covering strength of the bandage on the patient based on the contact pressure value includes judging whether the contact pressure value is in an optimal pressure range; in response to the judgment result that the contact pressure value is in the optimal pressure range, determining that the covering strength of the bandage is qualified; in response to the judgment result that the contact pressure value is not in the optimal pressure range, determining that the covering strength of the bandage is unqualified.

[0013] In one embodiment, after determining the contact area and non-contact area on the covering contour graphic according to the position of the covering demarcation point, the method further includes determining the bandage angle according to the shape information of the non-contact area and the covering contour graphic; and determining the degree of coverage of the bandage for the patient according to the bandage angle.

[0014] In one embodiment, determining the degree of coverage of the patient by the bandage based on the bandage angle information includes determining whether the bandage angle is in an optimal angle range; in response to the judgment result that the bandage angle is in the optimal angle range, determining that the degree of coverage of the bandage is qualified; in response to the judgment result that the bandage angle is not in the optimal angle range, determining that the degree of coverage of the bandage is unqualified.

[0015] In one of the embodiments, after determining the covering information of the bandage for the patient based on the sensing information, the method further includes judging whether the covering condition of the bandage for the patient meets the covering standard based on the covering information; in response to the judgment result that the covering condition of the bandage for the patient does not meet the covering standard, outputting a warning message.

[0016] The above-mentioned method for analyzing the coverage of the circumferential chest contraction bandage obtains the sensing information of the bandage and analyzes the sensing information to determine the coverage information of the bandage on the patient. The above-mentioned method for analyzing the coverage of the bandage can realize the automatic detection and analysis of the degree of bandage wrapping on the patient's chest before and during the chest compression device performs cardiopulmonary resuscitation on the patient. The operator can use the analysis results as a reference for operation to assist in completing the installation and adjustment of the bandage, and adjust the degree of bandage wrapping on the patient's chest to the optimal state to ensure the cardiopulmonary resuscitation effect of the chest compression device on the patient.

[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to understand the disclosure of the present invention more thoroughly and comprehensively.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] The present disclosure provides a method for analyzing the coverage degree of a circumferential chest contraction bandage, which can realize automatic detection and judge the degree of wrapping of the bandage of a chest compression machine on the patient's chest during cardiopulmonary resuscitation. Figure 1 1 is a flow chart of a bandage coverage analysis method in one embodiment of the present disclosure. In one embodiment, the method for analyzing the coverage of a circumferential chest contraction bandage may include the following steps S100 to S200.

[0040] Step S100: Acquire sensing information of the bandage.

[0041] The bandage coverage analysis method provided by the present disclosure can be applied to chest compression equipment. Figure 2This is a schematic diagram of the structure in which a chest compression device is fixed to a patient's chest through a bandage in one embodiment of the present disclosure. The chest compression device may include a bandage 10 and a pressing device 20. The bandage 10 may be fixedly connected to the pressing device 20 through two ends. When in use, the bandage 10 can surround the periphery of the patient's chest 30, and restrict the patient's chest 30 between the bandage 10 and the pressing device 20 in a manner that the two ends are fixed on the pressing device 20. When the pressing device 20 is working, the bandage 10 can prevent the patient's chest 30 from expanding outward to ensure the pressing effect of the pressing device 20 on the patient's chest 30. A sensing module may be provided on the bandage 10, and the sensing information of the bandage 10 is collected by the sensing module. Among them, the sensing information may be various information related to the use status of the bandage 10. For example, information related to the contact between the bandage 10 and the patient, information related to the morphology of the bandage 10 itself, and the like.

[0042] Step S200: Determine the covering information of the bandage for the patient according to the sensing information.

[0043] Since the sensing information is related to various information about the use status of the bandage 10, the use status of the bandage 10 can be analyzed based on the sensing information to determine the covering information of the bandage 10 on the patient. For example, it can be determined whether the bandage 10 is in full contact with the patient's body based on the contact information, and whether the patient is over-wrapped by the bandage 10 based on the shape information.

[0044] The bandage coverage degree analysis method provided by the present disclosure can realize automatic detection of the degree of bandage coverage of the patient's chest 30 before and during the chest compression device performs cardiopulmonary resuscitation on the patient by acquiring and analyzing the sensing information of the bandage 10. The operator can use the analysis result as an operation reference to assist in completing the installation and adjustment operation of the bandage 10, and adjust the degree of bandage 10 coverage of the patient's chest 30 to the optimal state, so as to ensure the cardiopulmonary resuscitation effect of the chest compression device on the patient.

[0045] In one embodiment, the sensing information may include shape information, contact information, and position information corresponding to the contact information. Shape information may refer to various types of information related to the shape of the bandage 10, including but not limited to the morphological information, size information, and shape profile information of the bandage 10. Contact information may refer to information related to the contact between the bandage 10 and the patient, including but not limited to touch information, infrared information, temperature information, humidity information, and pressure information. Among them, one piece of contact information may correspond to one piece of position information, that is, according to any piece of contact information, the position on the bandage 10 corresponding to the contact information can be located. The covering information may include the degree of tension, and the degree of tension of the bandage 10 can be used as one of the evaluation indicators of the covering state of the bandage 10.

[0046] Figure 3This is a flow chart of a method for determining the tension degree according to sensing information in one embodiment of the present disclosure. Determining the covering information of the bandage for the patient according to the sensing information may include the following steps S210 to S240.

[0047] Step S210: determining the wrapping contour of the bandage according to the shape information.

[0048] The sensing module provided on the bandage 10 can obtain shape information, contact information and position information corresponding to the contact information of the bandage 10 . Figure 4 This is a schematic diagram of a covering contour graphic in one embodiment of the present disclosure. The covering contour graphic of the bandage 10 can be formed based on the shape information of the bandage 10. Figure 4 The diagram shows a schematic diagram of one instantaneous state when the bandage 10 is wrapped around the patient's chest cavity 30. Figure 4 The dotted line figure is the chest contour figure, the solid line figure is the covering contour figure formed according to the shape information of the bandage 10 collected by the sensing module, C1 and C2 are the two end points of the bandage 10, and E1 and E2 are the two covering demarcation points on the bandage 10.

[0049] Step S220: Determine the location of the covering boundary point on the covering contour graphic according to the contact information and the position information.

[0050] The location of the wrapping boundary point on the wrapping contour graphic can be determined based on the contact information and the position information corresponding to the contact information. Figure 2 When the bandage 10 surrounds the periphery of the patient's chest 30 to restrict the patient's chest 30 between the bandage 10 and the pressing device 20, part of the bandage 10 contacts the patient's torso, and part of the bandage 10 does not contact the patient's torso. In this embodiment, the covering demarcation point may refer to the demarcation point between the part in contact with the patient and the part not in contact with the patient on the bandage 10, and the covering demarcation point position may refer to the position corresponding to the covering demarcation point on the bandage 10. For example, Figure 4 E1 and E2 in the figure are two covering demarcation points on the bandage 10, and the positions corresponding to E1 and E2 are the covering demarcation point positions.

[0051] Since one piece of contact information can correspond to one piece of position information respectively, the contact situation corresponding to any position on the bandage 10 can be determined according to the contact information and position information collected by the sensing module. That is, according to any piece of contact information, the position on the bandage 10 corresponding to the contact information can be located. According to the contact information and position information, it can be determined whether any position on the bandage 10 is in contact with the patient's body, thereby determining the position of the covering demarcation point. For example, the contact information collected on the part of the bandage 10 that contacts the patient is not 0, while the contact information collected on the part of the bandage 10 that does not contact the patient is 0. Based on this, the intersection point where the contact information is 0 and non-0 can be defined as the covering demarcation point, thereby determining the covering demarcation point position corresponding to the covering demarcation point.

[0052] Step S230: Determine the contact area and non-contact area on the covering contour graphic according to the position of the covering boundary point.

[0053] After the location of the covering demarcation point on the covering contour graphic is determined according to the contact information and the location information corresponding to the contact information, the contact area and the non-contact area on the covering contour graphic can be determined according to the location of the covering demarcation point. The contact area may refer to the graphic area on the covering contour graphic corresponding to the portion of the bandage 10 in contact with the patient, and the non-contact area may refer to the graphic area on the covering contour graphic corresponding to the portion of the bandage 10 not in contact with the patient.

[0054] In actual application, the two ends of the bandage 10 are used to be fixedly connected to the compression device 20 of the chest compression device, so the area between the end and the covering demarcation point position usually does not contact the patient, while the area between the two covering demarcation points is in contact with the patient. Therefore, the area between the end and the covering demarcation point position on the covering contour figure can be determined as the non-contact area, and the area between the two covering demarcation points can be determined as the contact area. Figure 4 In the figure, the area corresponding to the figure between point C1 and point E1 is the non-contact area, the area corresponding to the figure between point C2 and point E2 is the non-contact area, and the area corresponding to the figure between point E1 and point E2 is the contact area.

[0055] Step S240: Determine the tension of the bandage according to the shape information of the non-contact area.

[0056] Since the bandage 10 is used to restrain the patient's chest 30 when the compression device 20 performs cardiopulmonary resuscitation on the patient's chest 30, the fixing condition of the bandage 10 will affect the cardiopulmonary resuscitation effect of the chest compression device. In a preferred implementation, the restraining state of the bandage 10 on the patient's chest 30 can ensure that the compression device 20 and the patient's chest 30 will not loosen and separate during operation, and at the same time, the patient's chest 30 can be fully released or fully rebounded during the chest release period, which requires that the bandage 10 should not be tied too tightly or too loosely. If the bandage 10 is tied too tightly, it will affect the release or rebound of the patient's chest 30 during the chest release period, and if the bandage 10 is tied too loosely, it may cause the compression device 20 and the patient's chest 30 to loosen and separate during the compression process.

[0057] When the bandage 10 is in use, the use state of the bandage 10 can be judged from multiple dimensions, and the tension can be one of the evaluation indicators of the covering state of the bandage 10. Based on the tension of the bandage 10, it can be judged whether the covering state of the bandage 10 is appropriate. Since the shape information can intuitively show the outer contour of the bandage 10 during use, and the non-contact area of ​​the bandage 10 is mainly used for fixing and stretching, in this embodiment, the shape of the bandage 10 can be judged according to the shape information of the non-contact area, thereby determining the tension of the bandage 10.

[0058] Figure 5 This is a flow chart of a method for determining the tension of a bandage based on shape information of a non-contact area in one embodiment of the present disclosure. In one embodiment, determining the tension of a bandage based on the shape information of the non-contact area may include the following steps S241 to S245.

[0059] Step S241: Analyze the line shape of the non-contact area.

[0060] like Figure 2 As shown, when the bandage 10 is in use, the portion of the bandage 10 that contacts the patient is mainly used to wrap part of the patient's chest periphery, that is, the contact area corresponding to the portion of the bandage 10 that contacts the patient in the covering contour figure is usually a curved figure that matches the contour of the patient's chest 30, while the portion of the bandage 10 that does not contact the patient is mainly used for fixation, so that the bandage 10 as a whole plays a role in restraining the patient. In a suitable binding state, the bandage 10 is usually in a certain tension state, so that a certain restraining force can be provided to the patient. During normal use of the bandage 10, since there are no obstacles in the portion of the bandage 10 that does not contact the patient, when the bandage 10 is in a certain tension state, the line shape of the non-contact area of ​​the bandage 10 will be a straight line state. In this embodiment, the shape of the bandage 10 can be judged according to the line shape of the non-contact area of ​​the bandage 10, thereby determining the tension of the bandage 10.

[0061] Step S243: In response to the judgment result that the line shape of the non-contact area is a curve, it is determined that the bandage is not tensioned.

[0062] Figure 6 This is a graphical diagram showing that the non-contact area is a curve in one embodiment of the present disclosure. Figure 6 A schematic diagram is shown in which the non-contact area in the wrapping contour graph is a curve. Since the wrapping contour graph shows the outer contour of the bandage 10, when the non-contact area in the wrapping contour graph is a curve, the outer contour of the corresponding part of the non-contact area on the body of the bandage 10 is also distorted, that is, the bandage 10 is not in a tensioned state. Based on the judgment result that the bandage is not tensioned, it can be determined that the wrapping state of the current bandage 10 is unqualified. The operator can adjust the bandage 10 according to the wrapping contour graph and the judgment result that the bandage is not tensioned.

[0063] Step S245: In response to the judgment result that the line shape of the non-contact area is a straight line, it is determined that the bandage is tensioned.

[0064] Figure 7 This is a schematic diagram of a non-contact area as a straight line in one embodiment of the present disclosure. Figure 7 A schematic diagram is shown in which the non-contact area in the wrapping contour graph is a straight line. When the non-contact area in the wrapping contour graph is a straight line, the outer contour of the corresponding part of the non-contact area on the bandage 10 body is also straight, that is, the bandage 10 is in a tensioned state. Based on the judgment result of the tension of the bandage, it can be preliminarily judged that the wrapping state of the bandage 10 is qualified.

[0065] The analysis method provided by the present disclosure can not only determine whether the bandage 10 is taut, but also further determine whether the use state of the bandage 10 meets the requirements from other dimensions in combination with other information of the bandage 10, so as to ensure that the bandage 10 is in the best wrapping state. In some embodiments, the wrapping degree can also be one of the evaluation indicators of the wrapping state of the bandage 10.

[0066] In one embodiment, the wrapping contour graphic may include two wrapping demarcation points, and the wrapping information may include the degree of wrapping. Considering that the bandage 10 is usually fixed to the pressing device 20 through two ends, and the portion of the bandage 10 that contacts the patient is usually in the middle of the bandage 10, there are two contact / non-contact demarcation points on the bandage 10, and there are two wrapping demarcation points on the wrapping contour graphic accordingly.

[0067] Figure 8 This is a flow chart of a method for determining a degree of encapsulation based on sensing information in one embodiment of the present disclosure. After determining the position of the encapsulation boundary point on the encapsulation contour graphic based on the contact information and the position information, the method may further include the following steps S250 to S270.

[0068] Step S250: Analyze the wrapping contour pattern to determine the widest distance of the wrapping contour pattern in the lateral direction.

[0069] Step S260: Determine the boundary point spacing distance between two covering boundary point positions in the lateral direction.

[0070] Based on step S210 and step S220, the covering contour graphic can be obtained, and the positions of two covering demarcation points on the covering contour graphic can be determined. By analyzing the covering contour graphic and the two covering demarcation point positions, the widest distance of the covering contour graphic in the lateral direction and the demarcation point spacing distance between the two covering demarcation point positions in the lateral direction can be determined.

[0071] Fig. 9 This is a graphic schematic diagram of a covering contour graphic in another embodiment of the present disclosure, wherein E1 and E2 are two covering demarcation points on the bandage 10, respectively, L1 represents the demarcation point spacing distance between the two covering demarcation points in the transverse direction, and L2 represents the widest distance of the covering contour graphic in the transverse direction.

[0072] Step S270: Determine the coverage of the bandage on the patient according to the ratio of the demarcation point interval distance to the widest distance.

[0073] Fig.10 This is a schematic diagram of image analysis of a bandage wrapped around a patient's chest in four different wrapping states in one embodiment of the present disclosure. Fig.10 In the figure, L2 represents the widest distance of the covering contour figure in the transverse direction, L1 represents the dividing point spacing distance between the two covering dividing point positions in the transverse direction in the first case, L1' represents the dividing point spacing distance between the two covering dividing point positions in the transverse direction in the second case, L1'' represents the dividing point spacing distance between the two covering dividing point positions in the transverse direction in the third case, and L1''' represents the dividing point spacing distance between the two covering dividing point positions in the transverse direction in the fourth case.

[0074] In actual applications, the chest compression device may be used to perform cardiopulmonary resuscitation on patients of different body sizes, so the contact area between the bandage 10 and the patients of different body sizes is different, so the wrapping degree cannot be simply determined by the contact area between the bandage 10 and the patient. Although the body sizes of patients may be different, they usually conform to certain ergonomic proportions, so the wrapping degree can be determined by using the proportion parameter.

[0075] like Fig.10As shown, the higher the degree of wrapping of the bandage 10 for the patient's chest 30, the larger the area occupied by the portion of the bandage 10 in contact with the patient, and the narrower the demarcation point spacing distance L1 between the two wrapping demarcation points in the lateral direction. At the same time, since the widest distance L2 of the wrapping contour figure in the lateral direction is fixed, the value of the distance ratio L1 / L2 changes with the change of the degree of wrapping of the bandage 10 for the patient's chest 30. The higher the degree of wrapping of the bandage 10 for the patient's chest 30, the smaller the distance ratio L1 / L2. It can be seen that the distance ratio L1 / L2 between the demarcation point spacing distance L1 and the widest distance L2 can be used to reflect the degree of wrapping of the bandage 10 for the patient.

[0076] Fig.11 This is a flow chart of a method for determining the degree of bandage coverage based on a distance ratio in one embodiment of the present disclosure. In one embodiment, determining the degree of bandage coverage of a patient based on a distance ratio between the demarcation point interval and the widest distance may include the following steps S271 to S275.

[0077] Step S271: Determine whether the distance ratio is in the optimal ratio interval.

[0078] Step S273: In response to the judgment result that the distance ratio is in the optimal ratio interval, it is determined that the coverage degree of the bandage is qualified.

[0079] Step S275: In response to the judgment result that the distance ratio is not in the optimal ratio interval, it is determined that the coverage degree of the bandage is unqualified.

[0080] Considering that the bandage 10 should not be too tight or too loose when wrapping the patient, in practical applications, the optimal wrapping degree range of the bandage 10 for the patient can be limited by setting the optimal ratio range, so as to assist in judging whether the use state of the bandage 10 meets the operation requirements. When the distance ratio is not in the optimal ratio range, it is judged that the wrapping degree of the bandage 10 for the patient does not belong to the optimal wrapping degree range, so that it is determined that the wrapping degree of the current bandage 10 is unqualified; when the distance ratio is in the optimal ratio range, the wrapping degree of the bandage 10 for the patient belongs to the optimal wrapping degree range, so that it is determined that the wrapping degree of the current bandage 10 is qualified.

[0081] In a specific embodiment, the optimal ratio interval can be a numerical interval formed between a first ratio threshold and a second ratio threshold, wherein the first ratio threshold is less than the second ratio threshold. By comparing the distance ratio L1 / L2 with the first ratio threshold and the second ratio threshold, it can be determined whether the distance ratio L1 / L2 is in the optimal ratio interval. Furthermore, by comparing the distance ratio L1 / L2 with the first ratio threshold and the second ratio threshold, it can also be determined whether the wrapping degree of the bandage 10 is too loose, too tight or moderate, so that the operator can make targeted adjustments to the bandage 10 according to the judgment result.

[0082] Specifically, when the distance ratio L1 / L2 is less than or equal to the first ratio threshold, it can be determined that the bandage 10 is wrapped too tightly for the patient; when the distance ratio L1 / L2 is greater than the first ratio threshold and the distance ratio L1 / L2 is less than the second ratio threshold, it can be determined that the bandage 10 is wrapped moderately for the patient; when the distance ratio L1 / L2 is greater than or equal to the second ratio threshold, it can be determined that the bandage 10 is wrapped too loosely for the patient. At the same time, according to the judgment result that the bandage 10 is wrapped too tightly or the bandage 10 is wrapped too loosely, it can be determined that the wrapping degree of the bandage 10 is unqualified; according to the judgment result that the wrapping degree of the bandage 10 is moderate, it can be determined that the wrapping degree of the bandage 10 is qualified. When the operator determines that the wrapping degree of the bandage 10 is unqualified, the bandage 10 can be adaptively adjusted according to the judgment result that the wrapping degree is too tight or too loose.

[0083] In the embodiments provided by the present disclosure, the relevant values ​​are taken to 4 decimal places. In some embodiments, the value range of the first ratio threshold may be (0.7, 0.8), and the value range of the second ratio threshold may be (0.8, 0.95). Preferably, the value of the first ratio threshold is 0.7024, and the value of the second ratio threshold is 0.9077, that is, the optimal ratio interval may be (0.7024, 0.9077).

[0084] In some embodiments, the optimal value of the distance ratio L1 / L2 may be 0.8125. Based on this, the optimal ratio interval may be selected based on a certain ratio of 0.8125. For example, the optimal ratio interval may be selected based on 0.8125±0.05*0.8125. At this time, the value of the first ratio threshold may be 0.7719, the value of the second ratio threshold may be 0.8531, and the optimal ratio interval may be (0.7719, 0.8531). Preferably, the floating ratio may be between 0 and 10%. That is, the value range of the first ratio threshold may be (0.7313, 0.8125), and the value of the second ratio threshold may be (0.8125, 0.8938).

[0085] The analysis method provided by the present disclosure can not only determine the degree of wrapping of the bandage 10 on the patient, but also further determine whether the use state of the bandage 10 meets the requirements from other dimensions in combination with other information of the bandage 10, so as to ensure that the bandage 10 is in the best wrapping state. In some embodiments, the wrapping strength can also be one of the evaluation indicators of the wrapping state of the bandage 10.

[0086] In one embodiment, the sensing information may include pressure information and position information corresponding to the pressure information. The pressure information may refer to the pressure information on the bandage 10, and one piece of pressure information may correspond to one piece of position information, that is, according to any piece of pressure information, the position on the bandage 10 corresponding to the pressure information may be located.

[0087] Since one piece of pressure information can correspond to one piece of position information respectively, the pressure condition of any position on the bandage 10 can be determined based on the pressure information and position information collected by the sensing module. That is, whether any position on the bandage 10 is in contact with the patient's body and the pressure condition of any position on the bandage 10 can be determined based on the pressure information and position information. Furthermore, the position of the covering demarcation point can also be determined based on the pressure information and position information. For example, the pressure information collected on the part of the bandage 10 that contacts the patient is not 0, while the pressure information collected on the part of the bandage 10 that does not contact the patient is 0. Based on this, the intersection point where the pressure information is 0 and non-0 can be defined as the covering demarcation point, thereby determining the covering demarcation point position corresponding to the covering demarcation point.

[0088] Fig.12 This is a flow chart of a method for determining the covering force according to sensing information in one embodiment of the present disclosure. After determining the covering boundary point position on the covering contour graphic according to the contact information and the position information, the method may further include the following steps S280 to S310.

[0089] Step S280: determining a force analysis area on the wrapping contour graph according to the location of the wrapping demarcation point.

[0090] When using a chest compression device to perform cardiopulmonary resuscitation on a patient, the patient is usually asked to lie flat with the face facing upward, that is, part of the bandage 10 contacts the patient's back, and part of the bandage 10 contacts the patient's side torso. It can be imagined that the pressure received by the part of the bandage 10 contacting the patient's back is usually related to the patient's weight, and the pressure received by the part of the bandage 10 contacting the patient's side torso is usually related to the wrapping strength of the bandage 10. In this embodiment, the area on the wrapping contour image where the bandage 10 contacts the patient's side torso can be defined as a strength analysis area, and the wrapping strength of the bandage 10 on the patient can be determined based on the pressure information corresponding to the strength analysis area.

[0091] In this embodiment, the force analysis area can be determined according to the location of the covering demarcation point. Figure 4 A certain area extending from point E1 to point E2 in the illustrated envelope contour image is selected as a force analysis area.

[0092] In some other embodiments, the force analysis area may also be determined based on the location of the covering demarcation point and the widest distance of the covering contour pattern in the lateral direction. Fig. 9 In the illustrated wrapping contour image, the area intercepted by the distance L1 between the two wrapping demarcation points in the transverse direction and the widest distance L2 of the wrapping contour pattern in the transverse direction is defined as the force analysis area.

[0093] In some other embodiments, the force analysis area may also be determined by covering the widest distance of the contour pattern in the lateral direction. Fig. 9 In the illustrated covering contour image, an area intercepted within a certain distance above and below the position where the widest distance L2 of the covering contour graphic in the lateral direction is located is defined as a force analysis area.

[0094] Step S290: determining the contact pressure value according to the force analysis area, the pressure information and the position information.

[0095] After determining the force analysis area, the pressure information corresponding to each position can be determined according to the position information of each position in the force analysis area. The contact pressure value can be determined by analyzing the pressure information in the force analysis area. In this embodiment, different pressure information can be defined as contact pressure values ​​according to different selection methods of the force analysis area. For example, when the force analysis area is an area intercepted between the distance L1 of two covering demarcation points in the lateral direction and the widest distance L2 of the covering contour figure in the lateral direction, the mean value of the force in the force analysis area can be defined as the contact pressure value.

[0096] Step S300: determining the wrapping force of the bandage on the patient according to the contact pressure value.

[0097] When the bandage 10 provides covering force for the patient, the surface of the bandage 10 in contact with the patient will also receive the corresponding pressure exerted by the patient on the bandage 10. The tighter the bandage 10 wraps around the patient, the greater the pressure exerted by the patient on the bandage 10; the looser the bandage 10 wraps around the patient, the smaller the pressure exerted by the patient on the bandage 10. It can be seen that the contact pressure value of the bandage 10 can be used to express the covering force of the bandage 10 on the patient.

[0098] Preferably, the operator may wrap the bandage 10 unevenly on the patient due to improper wrapping, so that different areas of the bandage 10 receive different pressures, and the pressure on one side may be too high, while the pressure on the other side may be too low. Therefore, the areas where the bandage 10 contacts the two sides of the patient's body can be defined as two different force analysis areas, and the corresponding pressure information at each position in the two force analysis areas is analyzed to determine two different contact pressure values. Furthermore, the wrapping force of the bandage 10 on the two sides of the patient's body is determined based on the two different contact pressure values.

[0099] Fig.13 This is a flow chart of a method for determining the covering strength of a bandage according to a contact pressure value in one embodiment of the present disclosure. In one embodiment, determining the covering strength of a bandage on a patient according to the contact pressure value may include the following steps S301 to S305.

[0100] Step S301: determine whether the contact pressure value is in the optimal pressure range.

[0101] Step S303: In response to the judgment result that the contact pressure value is in the optimal pressure range, determining that the covering force of the bandage is qualified.

[0102] Step S305: In response to the judgment result that the contact pressure value is not in the optimal pressure interval, it is determined that the covering force of the bandage is unqualified.

[0103] Considering that the wrapping force of the bandage 10 on the patient should not be too large or too small, in actual application, the optimal pressure range of the bandage 10 on the patient can be set to assist in judging whether the use state of the bandage 10 meets the operation requirements. When the wrapping force of the bandage 10 on the patient does not belong to the optimal pressure range, it can be determined that the wrapping force of the current bandage 10 is unqualified; when the wrapping force of the bandage 10 on the patient belongs to the optimal pressure range, it can be determined that the wrapping force of the current bandage 10 is qualified.

[0104] In a specific embodiment, the optimal pressure interval can be a numerical interval formed between a first pressure threshold and a second pressure threshold, wherein the first pressure threshold is less than the second pressure threshold. By comparing the contact pressure value with the first pressure threshold and the second pressure threshold, it can be determined whether the contact pressure value is in the optimal ratio interval. Furthermore, by comparing the contact pressure value with the first pressure threshold and the second pressure threshold, it can also be determined whether the wrapping force of the bandage 10 is too large, too small or moderate, so that the operator can make targeted adjustments to the bandage 10 according to the judgment result.

[0105] Specifically, when the contact pressure value is less than or equal to the first pressure threshold, it can be determined that the wrapping force of the bandage 10 on the patient is too small; when the contact pressure value is greater than the first pressure threshold and the contact pressure value is less than the second pressure threshold, it can be determined that the wrapping force of the bandage 10 on the patient is moderate; when the contact pressure value is greater than or equal to the second pressure threshold, it can be determined that the wrapping force of the bandage 10 on the patient is too large. At the same time, according to the judgment result that the wrapping force of the bandage 10 is too large or the wrapping force of the bandage 10 is too small, it can be determined that the wrapping force of the bandage 10 is unqualified; according to the judgment result that the wrapping force of the bandage 10 is moderate, it can be determined that the wrapping force of the bandage 10 is qualified. When the operator determines that the wrapping force of the bandage 10 is unqualified, the bandage 10 can be adaptively adjusted according to the judgment result that the wrapping force is too large or too small.

[0106] When the areas where the bandage 10 contacts the two sides of the patient's torso are defined as two different force analysis areas, the pressure information corresponding to each position in the two force analysis areas is analyzed respectively, and two different contact pressure values ​​are determined, the judgment method of the two contact pressure values ​​is as described above and will not be repeated here. When the operator determines that the wrapping force of the bandage 10 on either side or both sides of the patient's torso is unqualified, the use state of the bandage 10 on either side or both sides of the patient's torso can be adaptively adjusted according to the judgment result of whether the wrapping force is too large or too small.

[0107] In some embodiments, the value range of the first pressure threshold may be (15, 25) N, and the value range of the second pressure threshold may be (45, 55) N. Preferably, the value of the first pressure threshold is 20 N, and the value of the second pressure threshold is 50 N, that is, the optimal pressure interval may be (20, 50) N.

[0108] In some embodiments, the optimal value of the contact pressure value may be 30N. Based on this, the optimal pressure interval may be selected based on a certain ratio of 30N up and down. For example, the optimal pressure interval may be selected based on 30N±0.05*30N. At this time, the value of the first pressure threshold may be 28.5N, the value of the second pressure threshold may be 31.5, and the optimal ratio interval may be (28.5, 31.5). Preferably, the floating ratio may be between 0 and 10%. That is, the value range of the first pressure threshold may be (27, 30), and the value of the second pressure threshold may be (30, 33).

[0109] The analysis method provided by the present disclosure can not only determine the degree of wrapping of the patient by the bandage 10 based on the ratio of the demarcation point interval distance to the widest distance, but also determine the degree of wrapping of the patient by the bandage 10 based on the angle information of the bandage.

[0110] Fig.14This is a flow chart of a method for determining the degree of covering according to sensing information in another embodiment of the present disclosure. In one embodiment, after covering the contact area and non-contact area on the contour graphic according to the position of the covering boundary point, the method may further include the following steps S310 to S320.

[0111] Step S310: determining the bandage angle according to the shape information of the non-contact area and the covering contour graphic.

[0112] In this embodiment, the bandage angle may be an angle corresponding to the bandage angle. The bandage angle may be an angle formed by a first ray and a second ray, wherein the first ray may be a ray that takes the covering demarcation point as an endpoint and extends in a direction away from the covering demarcation point from a straight line corresponding to the non-contact area in the covering contour figure, and the second ray may be a ray that takes the covering demarcation point as an endpoint and extends in a lateral direction. Fig.15 This is a schematic diagram of image analysis of bandage angles in another embodiment of the present disclosure. Fig.15 Where α represents the bandage angle, the endpoint of the bandage angle α is the covering demarcation point E1, the first ray extending in the lateral direction with the covering demarcation point E1 as the endpoint is one of the sides of the bandage angle α, and the second ray extending in the direction of point C1 with the covering demarcation point E1 as the endpoint is the other side of the bandage angle α.

[0113] In some other embodiments, other methods may be used to determine the angle information of the bandage. For example, the bandage angle α may be an angle formed by a first ray and a third ray, wherein the first ray may be a ray that takes the wrapping demarcation point as an endpoint and extends in a direction away from the wrapping demarcation point toward a straight line corresponding to a non-contact area in the wrapping contour figure, and the third ray may be a ray that takes the wrapping demarcation point as an endpoint and extends in a direction tangent to the wrapping contour figure.

[0114] Step S320: Determine the coverage of the patient by the bandage according to the bandage angle.

[0115] according to Fig.10 and Fig.15 It can be seen that the higher the degree of wrapping of the bandage 10 on the patient's chest 30, the smaller the angle between the portion of the bandage 10 that is not in contact with the patient and the transverse direction. At the same time, since the transverse direction is fixed, the bandage angle α changes with the change in the degree of wrapping of the bandage 10 on the patient's chest 30. The higher the degree of wrapping of the bandage 10 on the patient's chest 30, the smaller the bandage angle α. It can be seen that the bandage angle α can be used to reflect the degree of wrapping of the bandage 10 on the patient.

[0116] Fig.16This is a flow chart of a method for determining the degree of coverage of a patient by a bandage based on the angle of the bandage in one embodiment of the present disclosure. In one embodiment, determining the degree of coverage of a patient by a bandage based on the bandage angle information may include the following steps S321 to S325.

[0117] Step S321: Determine whether the bandage angle is in the optimal angle range.

[0118] Step S323: In response to the judgment result that the bandage angle is in the optimal angle range, determining that the coverage degree of the bandage is qualified.

[0119] Step S325: In response to the judgment result that the bandage angle is not within the optimal angle range, it is determined that the coverage degree of the bandage is unqualified.

[0120] Considering that the wrapping degree of the bandage 10 for the patient should not be too tight or too loose, in practical applications, the optimal angle range of the bandage 10 for the patient can be set to assist in determining whether the use state of the bandage 10 meets the operation requirements. When the bandage angle α of the bandage 10 does not belong to the optimal angle range, it can be determined that the wrapping degree of the current bandage 10 is unqualified; when the bandage angle α of the bandage 10 belongs to the optimal angle range, it can be determined that the wrapping degree of the current bandage 10 is qualified.

[0121] In a specific embodiment, the optimal angle interval can be a numerical interval formed between a first angle threshold and a second angle threshold, wherein the first angle threshold is less than the second angle threshold. By comparing the bandage angle α with the first angle threshold and the second angle threshold, it can be determined whether the bandage angle α is in the optimal angle interval. Furthermore, by comparing the bandage angle α with the first angle threshold and the second angle threshold, it can also be determined whether the wrapping degree of the bandage 10 is too loose, too tight, or moderate, so that the operator can make targeted adjustments to the bandage 10 according to the judgment result.

[0122] Specifically, when the bandage angle α is less than or equal to the first angle threshold, it can be determined that the bandage 10 is wrapped too tightly for the patient; when the bandage angle α is greater than the first angle threshold and the bandage angle α is less than the second angle threshold, it can be determined that the bandage 10 is wrapped moderately for the patient; when the bandage angle α is greater than or equal to the second angle threshold, it can be determined that the bandage 10 is wrapped too loosely for the patient. At the same time, according to the judgment result that the wrapping degree of the bandage 10 is too tight or the wrapping degree of the bandage 10 is too loose, it can be determined that the wrapping degree of the bandage 10 is unqualified; according to the judgment result that the wrapping degree of the bandage 10 is moderate, it can be determined that the wrapping degree of the bandage 10 is qualified. When the operator determines that the wrapping degree of the bandage 10 is unqualified, the bandage 10 can be adaptively adjusted according to the judgment result that the wrapping degree is too tight or too loose.

[0123] In some embodiments, the value range of the first angle threshold may be (30, 50)°, and the value range of the second angle threshold may be (70, 90)°. Preferably, the value of the first angle threshold is 45°, and the value of the second angle threshold is 75°, that is, the optimal pressure interval may be (45, 75)°.

[0124] In some embodiments, the optimal value of the bandage angle α may be 60°. Based on this, the optimal angle interval may be selected based on a certain floating ratio of 60°. For example, the optimal angle interval may be selected based on 60°±0.1*60°. At this time, the value of the first angle threshold may be 54°, the value of the second angle threshold may be 66°, and the optimal angle interval may be (54, 66). Preferably, the floating ratio may be between 0 and 20%. That is, the value range of the first angle threshold may be (48, 60), and the value of the second angle threshold may be (60, 72).

[0125] Fig.17 This is a flow chart of a bandage coverage analysis method in one of the embodiments of the present disclosure. In one of the embodiments, after determining the coverage information of the bandage for the patient based on the sensing information, the method may further include the following steps S330 to S340.

[0126] Step S330: Determine whether the bandage's coverage of the patient meets the coverage standard based on the coverage information.

[0127] The wrapping information may include any one or more of the tension, wrapping, and wrapping strength. After the wrapping information of the bandage 10 for the patient is determined according to the sensing information, it can be determined whether the use of the bandage 10 meets the wrapping standard according to the determination result of the wrapping information. In this embodiment, when any one or more of the tension, wrapping, and wrapping strength information is unqualified, it can be determined that the wrapping of the patient by the bandage 10 does not meet the wrapping standard; when each of the tension, wrapping, and wrapping strength information is qualified, it can be determined that the wrapping of the patient by the bandage 10 meets the wrapping standard.

[0128] Step S340: In response to the determination result that the bandage covering the patient does not meet the covering standard, output a warning message.

[0129] When it is determined that the wrapping of the bandage 10 on the patient does not meet the wrapping standard, information that the bandage 10 is incorrectly wrapped on the patient's chest 30 can be output to warn the operator. The warning information can also include specific unqualified items to prompt the operator to make improvements. For example, the warning information may include information such as the bandage is not tightened, the bandage is wrapped too tightly, and the bandage force at the left chest position of the patient is too large. Based on the warning information, the operator can not only determine that the current use status of the bandage 10 does not meet the operating requirements, but also understand what specific unqualified items are, so that targeted adjustments can be made according to different problems.

[0130] The bandage covering degree analysis method provided in the present invention can be used as a reference for operators' operations. The covering information obtained by automatic analysis is used to judge the usage status of the bandage 10. Therefore, when the above analysis method is applied to a chest compression device, the proficiency requirements of the chest compression device for the operator can be reduced, the convenience of using the chest compression device can be improved, and the application market of the chest compression device can be broadened.
