Description
Technical Field
The invention relates to the technical field of postoperative care appliances, in particular to a pressure control system based on a pressure adjustment model, and belongs to the technical field of ipc classification numbers A61F.
Background
The postoperative pressurizing nursing is a common means for preventing the subcutaneous hydrops of the surgical wound and related complications, but the pressure of various postoperative pressurizing devices used at present is difficult to average due to the different postoperative pressurizing devices and the structural limitations. The conventional sand bag squeezing mode is to fix the sand bag by using a fixing belt wound on the outer side of the body, and keep the sand bag between the puncture point and the fixing belt to fix and press the sand bag. The fixation of the sandbag and the selection of the weight of the sandbag can only be carried out by subjective judgment of doctors, and uneven pressure or too high pressure can easily cause local venous blood stasis, cause thrombus, wound edema and even cause infection. The traditional postoperative pressurization mode has various defects that the pressurization degree is difficult to control, the depressurization rate is difficult to control and the like when the traditional postoperative pressurization mode is used. Therefore, there is still a need for a pressure control system for post-operative progressive pressurization, adjustable pressure. The system can calculate the optimal pressurizing pressure required by each patient in a scientific exploration mode, further adjust the depressurization time according to a time sequence, and can perform standard and scientific pressurizing after operation. The invention is used for pressurized nursing of patients after operation, and belongs to the technical field of postoperative nursing tools.
Chinese patent CN103860331B discloses a pressure-adjustable limb postoperative compression bandaging device and bandaging method thereof. The device comprises a foot winding and binding air bag, a lower leg winding and binding air bag, a knee winding and binding air bag, a thigh winding and binding air bag, a seal, an air pump, a pressure gauge, a one-way valve or an inflating valve and an arteriovenous foot pump; each wrapping air bag is wrapped around the foot, the lower leg, the knee and the thigh and then sealed by a seal; the binding method provided by the patent comprises the following steps: wrapping the lower limb with clean soft lining, wrapping the device around the foot, lower leg, knee and thigh, and sealing; starting an air pump to pressurize each winding and wrapping air bag; when pulse pressurization is carried out on the foot, the air bag gas wrapped by foot wrapping is discharged, an arteriovenous foot pump is started, and pulse pressurization is carried out on the foot; after completion, the gas is vented, the seal is unsealed and the device is removed for sterilization. The patent has the advantages of simple structure, complete functions, controllable operation and even binding pressure, is beneficial to blood circulation, incision healing and functional recovery, prevents thrombosis and reduces incision infection rate. However, the disadvantage of this patent is that: the scientific calculation of the pressure required by the patient is omitted, the pressure of the patient is set depending on the self-magnitude of the pressure of the device and the working experience of medical staff, and for patients with various complications, the pressure is not adjusted in a multi-way mode, and special diseases such as deep venous thrombosis of lower limbs, deep venous thrombosis post-syndrome and the like cannot be inhibited in a targeted mode, so that the pressure can be used for simple bundling after operation.
Chinese patent application CN103690204a discloses a method and apparatus for treating postoperative wounds, comprising the steps of: (1) wound dressing, a. Cleaning the wound; b. placing the cold compress pad on the wound surface; (2) Pressurizing the abdominal cavity, c, placing the pressurizing bag on the cold compress pad, and enabling the pressurizing bag to be tightly attached to the cold compress pad; d. the pressure strength was tested, and the pressurized bag was added again when the pressure was insufficient and placed on the original pressurized bag. The technical scheme of the patent solves the problems that the wound after operation of a patient bleeds in a large area, and the medicine is invalid and then the sand bag is placed at the bottom of the abdomen for pressurization and bandaging to control the wound infection caused by postpartum hemorrhage. The patent can effectively control postoperative bleeding, reduce wound pain of patients, and simultaneously avoid the problems of wound lochia, equipment infection and the like. However, the disadvantage of this patent is that: the provision of pressure depends on the experience judgment of medical staff, and the subjective judgment operation is extremely easy to cause local venous blood stasis, cause thrombus, wound edema and even cause infection. For example, in the case of a patient whose course of progression changes, different pressure parameters may bring about different therapeutic effects. If the pressure parameters of the pressure equipment are not correspondingly adjusted after the disease development progress of the patient is changed, the healing rate of the patient is reduced and the recurrence rate is increased. The pressure adjustment mode based on the experience of medical staff has time delay and can cause error in pressure application, thereby reducing the cure rate of patients and even causing complications. The pressurization method has various defects that the pressurization degree is difficult to control, the depressurization rate is difficult to control and the like when the pressurization method is used.
For example, if a patient develops deep vein thrombosis in the lower extremities, existing post-operative compression protocols typically require three procedures: the patients are found to have deep venous thrombosis of lower limbs; the doctor judges the degree of deep venous thrombosis of the lower limb of the patient; the doctor performs corresponding post-operation pressurization treatment according to experience. The post-operation pressurizing treatment of the patient in the prior art depends on the experience judgment of doctors, the corresponding treatment cannot be performed in time, and the pressurizing time and the pressurizing frequency are selected and adjusted according to the specific condition of the patient. After the deep vein thrombosis of the lower limb occurs, the postoperative pressurizing range is adjusted to be within 20 mmHg-40 mmHg, so that the recurrence of the deep vein thrombosis of the lower limb is avoided. However, due to the change of the patient's disease progress, the pressure parameters also need to be changed correspondingly, and doctors often manage a plurality of patients at the same time, so that the change of the patient's disease can not be found in time, and the corresponding pressure parameter changing scheme is difficult to be obtained directly. For example, when the progression of varicose veins of the lower limb of a patient is severe, a pressure of 30 mmHg to 40 mmHg is required to be applied to the lower limb of the patient. When the varicose vein of the lower limb of the patient is primarily healed, the pressure parameter of the lower limb of the patient needs to be changed into 20 mmHg-30 mmHg in time. Failure to make a corresponding adjustment to the pressure parameters of the pressure device for an extended period of time may result in tissue damage to the patient. In this regard, the invention provides a pressure control system based on a pressure adjustment model according to comprehensive factors such as the disease development process of the patient, the lesion part, the pressure value adaptation range, the patient tolerance and compliance, etc., so as to perform individual selection and adjustment, thereby enabling the patient to generate the least adverse reaction and achieving the optimal treatment effect.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.
Disclosure of Invention
In order to overcome the shortcomings of the prior art, the present invention provides a pressure control system based on a pressure adjustment model, comprising: a compression unit for applying a post-operative pressure; and the pressure supply unit is used for supplying pressure to the compression unit. The system further comprises a monitoring unit. Preferably, the monitoring unit comprises a monitoring part and a processing module. The monitoring part is configured to monitor postoperative pressure data of a patient and send the postoperative pressure data to the processing module; in the case where the patient is pressurized after the operation and wears the compression unit, the processing module transmits an adjustment signal of the adjustment pressure corresponding to the post-operation pressure data to the pressure supply unit by establishing a pressure adjustment model. The pressure control system provided by the invention comprehensively considers the individual sign and illness state of the patient, and then generates a pressure parameter sequence by comprehensively considering the pressurizing condition required by the patient, so as to achieve the purpose of personalized calculation and judgment of the pressure parameter required by the patient. And the pressure control system provides optimal pressure, pressurization duration time and the like, so that the problems that the postoperative pressurization pressure is uneven or too high, the pressurization degree is difficult to control and the depressurization rate is difficult to control are solved. In addition, the invention also solves the problem that the manpower resources of hospitals are relatively tense, and the postoperative pressurization attention of a plurality of patients cannot be considered.
According to a preferred embodiment, the processing module builds the pressure adjustment model based on the post-operative compression data and controls the pressure parameter adjustment by the pressure supply unit. The processing module provides a personalized pressure adjustment model for the patient by assessing the individual characteristics, disease progression, and degree of pressure of the patient from a global post-operative consideration of the patient. And the optimal pressure regulation set by the processing module can prevent blood stasis from locally occurring and reduce the influence on local blood circulation while achieving the purpose of postoperative pressurization. Through the pressure adjustment model generated by the processing module, the patient can be effectively bound by postoperative pressurization.
According to a preferred embodiment, the post-operative compression data includes at least a post-operative characteristic level, an internal pressure change of the compression unit, an individual patient characteristic, and a progress of the condition. Preferably, in response to the acquisition of the post-operation pressure data, the processing module processes the post-operation pressure data into the pressure adjustment model, so that the pressure parameter of the pressure supply unit is dynamically adjusted if the patient is monitored by the monitoring part in real time. The processing module fully considers objective indexes of the patient, wherein the objective indexes comprise individual characteristics, disease development and the like, and the problem that medical staff with abundant working experience are lacking in the current postoperative pressurizing operation is effectively solved. The invention depends on the automation to judge the individual sign of the patient in many ways, scientifically adjusts the optimal pressurizing pressure required by each patient, standardizes the postoperative pressurizing operation, and prevents the conditions of pain, infection and interference to the functional recovery of the patient.
According to a preferred embodiment, the pressure parameter adjustment of the pressure supply unit comprises a stepwise pressure adjustment and a time-series pressure reduction adjustment. Preferably, the stepwise pressurization adjustment means that different levels of pressure are applied stepwise in time series. The time sequence depressurization refers to gradual decompression according to a time sequence.
According to a preferred embodiment, in case the processing module determines that the pressure adjustment model has changed, the processing module controls the pressure parameter applied by the pressure supply unit to the lower limb of the patient based on the change characteristic of the change in the pressure adjustment model. Preferably, the processing module controls the pressure supply unit to make an adjustment of a pressure parameter based on the change in the desired adjustment being characterized by a weight of the pressure adjustment model. Different individual characteristics of a patient can affect the pressure parameters of their post-operative pressurization. For example, a patient has high muscle relaxation, which makes it impossible to achieve a good compression treatment under a certain pressure, and it is necessary to perform compression treatment. And simultaneously, the duration of pressurizing the patient needs to be shortened due to higher muscle relaxation of the patient so as to prevent blood stasis caused by overhigh local pressure. For another example, patients with lower venous pressure may not be able to provide pressure in excess of the venous pressure to prevent exacerbation of bleeding from the surgical wound. According to the pressure parameter adjusting method and device, the pressure parameter adjustment is carried out in real time according to the recovery condition and the treatment condition of the patient in the postoperative pressurization process, so that the recovery speed of the patient is increased.
According to a preferred embodiment, when at least one of the individual characteristics, the progress of the illness state and/or the post-operation characteristic level in the post-operation pressure application data is changed, the monitoring section acquires at least one corresponding change characteristic of the change of the pressure adjustment model, thereby selecting the pressure parameter to be adjusted based on the traversed change characteristic weight, so that the adjusted pressure supply unit acts on the lower limb of the patient. The reason for the arrangement of the scheme is that: in the case of a patient with a change in the progress of their disease, different pressure parameters may lead to different therapeutic effects. If the pressure parameters of the pressure supply unit are not correspondingly regulated after the disease development progress is changed, the healing rate is reduced and the recurrence rate is increased. For example, when a patient with venous leg ulcers is treated with postoperative pressure, the pressure parameter of the corresponding pressure supply unit obtained by the pressure adjustment model is the treatment pressure applied to 30 mmHg or more. And after the venous ulcer of the lower limb heals, the pressure supply unit is continuously used for postoperative pressurization, but the pressure parameter of the pressure supply unit needs to be adjusted to 20 mmHg-30 mmHg. In this regard, the invention provides a pressure control system based on a pressure adjustment model according to comprehensive factors such as the disease development process of the patient, the lesion part, the pressure value adaptation range, the patient tolerance and compliance, etc., so as to perform individual selection and adjustment, thereby enabling the patient to generate the least adverse reaction and achieving the optimal treatment effect.
According to a preferred embodiment, the processing module determines the patient's pressure regulation scheme based on the patient's desired optimal pressure level and the desired pressure duration when the processing module makes at least one adjustment of the pressure parameter to the pressure supply unit based on the pressure regulation model. The invention calculates the optimal pressurizing pressure required by each patient, and further adjusts the depressurization time according to the time sequence, so that the pressure can be standardized and scientifically increased after operation, and the problems that the pressurizing pressure is uneven or too high after operation, the pressurizing degree is difficult to control, and the depressurizing rate is difficult to control are solved. The invention is actually placed on the physical condition of a patient, and a pressure adjustment scheme is established through the establishment of a pressure adjustment model and based on the change of the physical condition or the rest condition. The pressure adjustment regimen includes at least an optimal pressure level and a desired pressure duration for the patient. The above-described desired optimum pressure level and desired pressure duration are dependent on the physical condition of the patient. For example, the pressure level, frequency, duration, etc. of post-operative pressurization that the patient needs to perform during this stage of the condition. Through the scheme, the personalized real-time pressure adjustment scheme for the patient can be formulated, so that the treatment efficiency of postoperative pressurized nursing is improved, and complications are prevented.
According to a preferred embodiment, in case that the postoperative pressurizing time period required by the patient is greater than the preset postoperative pressurizing time period, the processing module adjusts the pressure parameter of the pressure supply unit according to the real-time variation of the postoperative pressurizing data, so as to adjust the required pressure parameter according to the real-time variation of the postoperative pressurizing data on the basis of at least one adjustment of the pressure parameter. The lack of a targeted intelligent decision on the condition of a patient and related complications in the prior art leads to overlong process of postoperative pressurized nursing and even to careless mistakes in postoperative pressurized nursing. For example, the pressure socks and other methods adopted in the prior art are difficult to achieve the result of accurate control for postoperative pressurized nursing of patients, and complications of postoperative patients cannot be avoided. The invention realizes the establishment of the personalized pressure adjustment scheme of the patient through the establishment of the pressure adjustment model, can meet the postoperative care requirement of the patient and the physiological characteristics of the patient, and greatly reduces the possibility of complications.
According to a preferred embodiment, the monitoring part provides supplementary real-time post-operation pressure data for the post-operation pressure data change condition monitored during at least one adjustment of the pressure parameter recorded by the processing module in a data interaction manner, so that the processing module can perform optimized pressure adjustment of the pressure adjustment scheme according to the real-time post-operation pressure data. The prior art is unable to address the patient's varying complications and related transformations, such as clinical staging of edema or the extent of tissue fibrosis, etc. Because the physical sign of the patient is continuously changed in the treatment process, a doctor can not realize the real-time and targeted pressure supply adjustment for the change, the treatment period of the patient is prolonged, and even the disease of the patient recurs. In this way, the pressure parameter provided by the pressure supply unit is enabled to accord with the current situation of the patient by introducing one or even more optimized adjustments of the pressure adjustment, so that the treatment period of the patient is shortened, and the treatment efficiency is improved.
According to a preferred embodiment, the optimal pressure adjustment is adjusted in a cross-wise manner in different adjustment schemes based at least on the same pressure parameter to determine the pressure parameter of the pressure supply unit required by the patient. Preferably, the different adjustment schemes of the same pressure parameter means: the same type of pressure parameter is adjusted for different pressure adjustment schemes to determine the patient's condition for treatment at the current pressure. Because the medical evidence conforming to the linearity rule is lacking in taking different pressure measures for different patients, namely, the different pressure measures have different treatment effects for different patients, and the reasons (including psychological reasons and other complex factors) causing the different treatment effects are difficult to judge by the current technical means, the invention proposes to improve the treatment efficiency of postoperative pressurization by optimizing the pressure adjustment mode, and prevent the pressure parameter from being adjusted in time after the patient signs are changed.

The following detailed description refers to the accompanying drawings.
The processing module 302 may execute related instructions or programs using the general purpose central processing unit CPU (Central Processing Unit), the application specific integrated circuit ASIC (Application Specific Integrated Circuit), a microprocessor, or one or more integrated circuits to implement the present invention. The processing module 302 can also include a device for input and a device for output. The input devices may include a mouse, a keyboard, a language input device, a touch device, an action device for detecting a non-contact gesture of a user or a combination of related components, etc. The output devices may include a display screen, a projection device, and the like. The processing module 302 can be connected to the rest of the computing devices of the hospital.
Example 1
Various postoperative pressurizing devices used at present are difficult to average in pressure. The conventional sand bag squeezing mode is to fix the sand bag by using a fixing belt wound on the outer side of the body, and keep the sand bag between the puncture point and the fixing belt to fix and press the sand bag. The fixation of the sandbag and the selection of the weight of the sandbag can only be carried out by subjective judgment of doctors, and uneven pressure or too high pressure can easily cause local venous blood stasis, cause thrombus, wound edema and even cause infection. The traditional postoperative pressurization mode has various defects that the pressurization degree is difficult to control, the depressurization rate is difficult to control and the like when the traditional postoperative pressurization mode is used. Therefore, there is still a need for a pressure control system for post-operative progressive pressurization, adjustable pressure. The system can calculate the optimal pressurizing pressure required by each patient in a scientific exploration mode, further adjust the depressurization time according to a time sequence, and can perform standard and scientific pressurizing after operation.
The pressure control system provided by the embodiment comprehensively considers the individual sign and illness state of the patient, and then generates a pressure parameter sequence to achieve the purpose of personalized calculation and judgment of the pressure parameters required by the patient. And the pressure control system provides optimal pressure, pressurization duration time and the like, and solves the problems that the post-operation pressurization pressure is uneven or too high, the pressurization degree is difficult to control, and the depressurization rate is difficult to control. In addition, the embodiment also solves the problem that the manpower resources of hospitals are relatively tense, and the postoperative pressurization attention of a plurality of patients cannot be considered.
The embodiment provides a pressure control system based on a pressure adjustment model, which is used for post-operation gradual pressurization and adjustable pressure. As shown in fig. 1, the pressure control system provided in this embodiment at least includes: compression unit 100, pressure supply unit 200, and monitoring unit 300. The compression unit 100 and the pressure supply unit 200 are connected by a pressure supply pipe 201. The monitoring unit 300 includes a monitoring unit 301 and a processing module 302. The medical staff classifies and rates the postoperative features of the patient according to the working experience and postoperative care standard and inputs the classification and rating result to the monitoring unit 301. The postoperative features at least comprise limb parts of patients, puncture points, wound areas, blood pressure parameters and blood coagulation capability. The monitoring part 301 acquires the post-operation feature level of the patient, and transmits the post-operation feature level to the processing module 302, and the processing module 302 calculates a pressure parameter based on the post-operation feature level to adjust the pressure applied by the pressure supply unit 200 to the compression unit 100. The pressure parameters include at least a post-operative optimal pressure, a duration of pressurization, an optimal pressure duration, and a duration of depressurization. The higher the post-operative characteristic level of the patient, e.g., the higher the clotting capacity level, the corresponding pressurization duration, optimal pressure duration, depressurization duration are correspondingly shorter. Preferably, the monitoring section 301 is capable of collecting and storing post-operation pressure data including the post-operation feature level of the patient, the internal pressure variation of the compression unit 100, the individual features of the patient, and the condition provided by medical staff. Preferably, the processing module 302 is configured to: in the case where the patient performs post-operation pressurization and wears the compression unit 100, the control pressure adjustment model transmits an adjustment signal of the adjustment pressure corresponding to the post-operation pressurization data to the pressure supply unit 200. The compression unit 100 makes a corresponding pressure change based on the adjustment signal. Preferably, the pressure adjustment model is generated by the processing module 302 based on the post-operation pressure data acquired by the monitoring section 301. For example, the processing module 302 may send a stepwise pressurization adjustment signal to the pressure supply unit 200, and when the pressure is reduced, the monitoring unit 300 may send a signal for adjusting the depressurization rate of the compression unit 100 according to a time sequence, and the monitoring unit 301 monitors the internal pressure of the compression unit 100 and feeds back to the processing module 302. Preferably, the step-by-step pressurization is to gradually apply different levels of pressure in time sequence, and the time sequence depressurization is to gradually depressurize in time sequence.
Preferably, the processing module 302 provides a personalized pressure adjustment model for the patient by assessing its individual characteristics, disease progression, and degree of pressure from a global post-operative consideration of the patient. And the optimal pressure regulation set by the processing module can prevent blood stasis from locally occurring and reduce the influence on local blood circulation while achieving the purpose of postoperative pressurization. By means of the pressure adjustment model generated by the processing module 302, the patient can be effectively pressure bandaged after operation. The processing module 302 fully considers objective indicators of the patient, wherein the objective indicators include individual characteristics, disease progression, etc., and effectively solves the problem of lack of medical staff with abundant working experience in the current post-operative pressurization operation. The embodiment relies on automation to judge the individual physical sign of the patient in many ways, so that the optimal pressurizing pressure required by each patient is scientifically adjusted, the postoperative pressurizing operation is standardized, and the conditions of pain, infection and interference to the functional recovery of the patient are prevented. Preferably, the processing module 302 records the removal time required to remove the compression unit 100 for each patient based on the personalized pressure adjustment model for each patient to issue a reminder to medical personnel if the patient compression time is equal to the removal time. The reminding information can be a reminding sign such as a reminding sound, a flashing lamp and the like.
Various parameters of post-operation pressurization in the prior art depend on experience judgment of doctors, but due to excessive indexes required to be considered for adjusting pressure parameters, the prior medical institutions often combine various evaluation tables to determine related indexes. Therefore, there are inevitable problems in that the index consideration is not comprehensive, the expression is wrong in the patient evaluation, the treatment flow is delayed, and the like. Especially for complex diseases (such as deep vein thrombosis of lower limbs) and more postoperative complications, how to perform corresponding pressure adjustment based on various factors of the diseases and related complications and how to formulate a pressure adjustment scheme meeting the physical requirements of patients and the conditions of the diseases are problems which are difficult to solve in the prior art.
According to a preferred embodiment, the processing module 302 acquires post-operative compression data in the monitoring portion 301. Preferably, the post-operative stress data includes post-operative feature grade, individual features, and progress of the condition. Preferably, the post-operative features include at least a patient limb portion, a puncture site, a wound area, a blood pressure parameter, a clotting capability. The postoperative feature grade can be obtained by classifying and grading postoperative features of patients according to working experience and postoperative care standards by medical staff. Preferably, the post-operative feature level can also be retrieved by the processing module 302 from a medical database for similar cases, resulting in a level of the post-operative feature. In response to the acquisition of the post-operative compression data, the processing module 302 processes it as a pressure adjustment model so that the pressure parameters of the pressure supply unit 200 are dynamically adjusted with the patient monitored by the monitoring portion 301 in real time. Preferably, the method comprises the steps of. The processing module 302 issues a gradual pressurization adjustment signal or a depressurization rate signal based on the pressure adjustment model. The medical database is, for example, a patient database of a medical institution. The medical facility can be a hospital, medical center, clinic, or other facility associated with storing patient medical records. The processing module 302 requests acquisition of post-operative compression data from a patient database of the medical facility. The post-operative compression data can be temporarily or permanently stored in a memory module of the processing module 302. The processing module 302 performs a screening process on the acquired post-operative compression data. The post-operation pressure data refers to data related to pressure applied to a portion to be treated of a patient, and includes pressure, post-operation feature level, individual feature, progress of disease, and the like.
According to a preferred embodiment, the processing module 302 adjusts the pressure parameters of the pressure supply unit 200 based on a pressure adjustment model. Preferably, the processing module 302 builds the pressure adjustment model based on at least one of individual characteristics, progress of the condition, and/or post-operative characteristic levels in the post-operative compression data. In particular, different individual characteristics of a patient can affect the pressure parameters of their post-operative pressurization. For example, a patient has high muscle relaxation, which makes it impossible to achieve a good compression treatment under a certain pressure, and it is necessary to perform compression treatment. And simultaneously, the duration of pressurizing the patient needs to be shortened due to higher muscle relaxation of the patient so as to prevent blood stasis caused by overhigh local pressure. For another example, patients with lower venous pressure may not be able to provide pressure in excess of the venous pressure to prevent exacerbation of bleeding from the surgical wound.
Deep venous thrombosis of the lower extremities is one of the most common and dangerous complications in hospitalized patients for the progress of their condition. The processing module 302 performs a treatment of post-operative compression based at least on a prophylactic assessment of deep vein thrombosis of the lower limb. Particularly for high risk and perioperative patients, the processing module 302 performs pressure regulation of post-operative pressurization based on the patient's surgical progress or disease progression, thereby reducing the incidence of deep vein thrombosis of the lower limb. Patients with deep vein thrombosis of the lower extremities are also at risk of developing post deep vein thrombosis syndrome. The processing module 302 obtains the progress of the patient's condition. The deep venous thrombosis of the lower limb is taken as an example. The processing module 302 obtains information about the age, body mass index, past history of primary venous insufficiency, proximal deep vein thrombosis, recurrence of ipsilateral deep vein thrombosis, time of occurrence of acute deep vein thrombosis of lower limb, venous symptoms after occurrence of acute deep vein thrombosis of lower limb, and D-dimer level within weeks to months after acute deep vein thrombosis of lower limb, and the like, and alleviates such symptoms in the patient by adjusting the duration of pressurization, the magnitude of pressurization, the duration of depressurization, and the magnitude of depressurization. Namely, after the occurrence of the deep vein thrombosis of the lower limb, the postoperative pressurizing range is adjusted to be within 20 mmHg-40 mmHg, so that the recurrence of the deep vein thrombosis of the lower limb is avoided. For a patient diagnosed with deep vein thrombosis syndrome, relieving symptoms of the patient with a pressure parameter of postoperative pressurization of 20 mmHg-30 mmHg in a first time sequence, and adjusting the pressure parameter of postoperative pressurization to 30 mmHg-40 mmHg or 40 mmHg-50 mmHg in a second time sequence and/or a third time sequence. Preferably, the treatment module 302 also provides for cyclically progressive, repetitive compression of the patient's limb by intermittent compression. For a conventional patient, pressures of 45 mmHg, 35 mmHg and 30 mmHg are required to be applied to the ankle, the lower leg and the thigh of the patient, and for a patient with the deep vein thrombosis syndrome, the duration of the pressure is adjusted to 20 min/time to 30 min/time, 2 times to 3 times a day, and the optimal compression range is between 30 mmHg and 50 mmHg. The postoperative features at least comprise limb parts of patients, puncture points, wound areas, blood pressure parameters and blood coagulation capability. The medical staff classifies and rates the postoperative features of the patient according to the working experience and postoperative care standard and inputs the classification and rating result to the monitoring unit 301. For example, when the limb portions of the patient are ankle, lower leg and thigh, respectively, the optimal compression amounts thereof are 45 mmHg, 35 mmHg, 30 mmHg, respectively. The pressure was also rated for evaluation of patient wound area, clotting ability, and wound depth. Where the patient's wound area is small, the treatment module 302 will fine tune the optimal compression size down to prevent wound edema or exacerbate wound bleeding. The optimal compression level is also fine-tuned by the processing module 302 to prevent excessive bleeding from the wound or painful infection when the patient has poor clotting capabilities. It should be noted that the fixing positions (such as ankle, calf and thigh) provided in the above embodiments are not meant to be fixed only at this position, and medical staff can perform position adjustment according to the needs of the patient, including adjustment to the proximal end of femoral artery or lower limb. The lack of a targeted intelligent decision on the condition of a patient and related complications in the prior art leads to overlong process of postoperative pressurized nursing and even to careless mistakes in postoperative pressurized nursing. For example, the pressure socks and other methods adopted in the prior art are difficult to achieve the result of accurate control for postoperative pressurized nursing of patients, and complications of postoperative patients cannot be avoided. The invention realizes the establishment of the personalized pressure adjustment scheme of the patient through the establishment of the pressure adjustment model, can meet the postoperative care requirement of the patient and the physiological characteristics of the patient, and greatly reduces the possibility of complications.
It should be noted that the pressure adjustment model of the present embodiment includes the pressure adjustment scheme for performing pressure adjustment for each type of post-operation pressure data. The pressure adjustment scheme can be derived by the processing module 302 retrieving a medical database. The processing module 302 is used as a main body for adjustment, and adjusts the pressure parameter of the pressure supply unit 200 according to the information contained in the pressure adjustment model. For example, after acquiring the progress of the patient's condition, individual signs, and post-operative feature levels, the processing module 302 invokes and selects a corresponding pressure adjustment scheme to adjust the pressure parameters of the pressure supply unit 200. The pressure parameters include time of time series, pressure duration, pressure magnitude, manner of pressure provision (e.g., gap type), etc. Specifically, the pressure adjustment model provided in the present embodiment can be one of a conceptual model or a mathematical model, that is, modeling a database. The laws, mechanisms and activities of things in the real world are qualitatively described and illustrated in the form of combinations of diagrams, words, symbols, data layers, meshes, relationships, object-oriented and the like. The pressure adjustment model provided in this embodiment includes integration of data related to the pressure adjustment scheme, such as the pressure magnitude adjustment scheme, the duration scheme, and the like.
According to a preferred embodiment, the processing module 302 builds the pressure adjustment model based on at least one of individual characteristics, progress of disease progression, and/or post-operative characteristic levels in the post-operative compression data. Preferably, the processing module 302 adjusts parameters of post-operative pressurization based on the constructed pressure adjustment model. Preferably, in the case that the processing module 302 determines that the pressure adjustment model changes, the processing module 302 controls the pressure parameter applied by the pressure supply unit 200 to the lower limb of the patient based on the change characteristic of the change in the pressure adjustment model. Preferably, the processing module 302 controls the pressure supply unit 200 to make adjustments to the pressure parameters based on the changes in the desired adjustments being characterized by the weights of the pressure adjustment model. Specifically, for the pressure adjustment model constructed by the processing module 302, the selection of pressure parameters is important when at least one of the individual characteristics, progress of disease progression, and/or post-operative characteristic level in the post-operative compression data changes. Preferably, the monitoring part 301 acquires at least one corresponding change feature of the change of the pressure adjustment model, so as to select the pressure parameter to be adjusted based on the traversed change feature weight, so that the adjusted pressure supply unit 200 acts on the lower limb of the patient. The reason for the arrangement of the scheme is that: in the case of a patient with a change in the progress of their disease, different pressure parameters may lead to different therapeutic effects. If the pressure parameters of the pressure supply unit 200 are not adjusted after the progress of the disease is changed, the healing rate is reduced and the recurrence rate is increased. For example, when a patient with venous leg ulcers is treated with postoperative pressure, the pressure parameter of the corresponding pressure supply unit 200 obtained by the pressure adjustment model is the treatment pressure applied to 30 mmHg or more. And after the venous ulcer of the lower limb heals, the pressure supply unit 200 is continuously used for postoperative pressurization, but the pressure parameter is required to be adjusted to be 20 mmHg-30 mmHg. For another example, in the case of performing the postoperative compression treatment for patients with venous leg ulcers as well, it is necessary to select different pressure levels for the postoperative compression due to different patient tolerability. Preferably, the processing module 302 controls the pressure supply unit 200 to make adjustments to the pressure parameters based on the patient's tolerability weight. Preferably, the processing module 302 selects the patient's pressure level based on the patient's tolerability weight. Preferably, the pressure level of the patient is higher than the pressure of the venous return of the patient. I.e. the pressure of the patient is higher than the pressure of the venous return of the patient. Preferably, the processing module 302 also controls the pressure supply unit 200 to make adjustments to the pressure parameters based on patient compliance weights. That is, the adjustment of the pressure parameter of the pressure supply unit 200 is performed by the self-sense of the patient. When skin damage, allergy, numbness, etc. occurs, the processing module 302 controls the pressure supply unit 200 to adjust the pressure parameters by the patient's compliance weights.
According to a preferred embodiment, the processing module 302 controls the pressure parameters applied by the pressure supply unit 200 to the patient's lower limb based at least on the progress of the condition in the pressure adjustment model. Preferably, the processing module 302 corrects the pressure parameter applied by the pressure supply unit 200 to the lower limb of the patient in case of a change in the progress of the patient's condition in the pressure adjustment model. For patients in the acute or oedema phase, higher pressure values are required. For patients in the chronic or healing phase, the pressure parameters of the pressure supply unit 200 may be gradually reduced. Taking a patient with varicose vein of the lower limb as an example, when the disease development progress of the varicose vein of the lower limb of the patient is mild, the processing module 302 controls the pressure parameter applied by the pressure supply unit 200 to the lower limb of the patient to be 15 mmHg-20 mmHg. When the course of the patient's lower limb varicose vein is moderate, the processing module 302 controls the pressure parameter applied by the pressure supply unit 200 to the patient's lower limb to be 20 mmHg-30 mmHg. When the disease development progress of the varicose vein of the lower limb of the patient is severe, the pressure parameters applied by the pressure supply unit 200 to the lower limb of the patient are 30 mmHg-40 mmHg. Preferably, the processing module 302 adjusts the pressure parameters of the pressure supply unit 200 based on the results of the periodic assessment and review of the patient's condition. Preferably, the processing module 302 also controls the pressure parameters applied by the pressure supply unit 200 to the patient's lower limb based on individual features in the pressure adjustment model. Taking the lower limb portion of the patient as an example, when the ankle portion of the patient needs to apply pressure, the processing module 302 controls the pressure parameter applied by the pressure supply unit 200 to the lower limb of the patient to be 40 mmHg to 60 mmHg. In the case where the patient's lower leg portion needs to exert pressure, the processing module 302 controls the pressure parameter exerted by the pressure supply unit 200 to be 30 mmHg-40 mmHg. Under the condition that the knee joint part of the patient needs to apply pressure, the processing module 302 controls the pressure parameter applied by the pressure supply unit 200 to the lower limb of the patient to be 20 mmHg-30 mmHg. Under the condition that the thigh part of the patient needs to exert pressure, the processing module 302 controls the pressure parameters exerted by the pressure supply unit 200 on the lower limb of the patient to be 10 mmHg-20 mmHg. The purpose of the pressure adjustment model provided in this embodiment is to perform individual pressure selection and adjustment according to comprehensive factors such as patient disease development process, lesion site, pressure value adaptation range, patient tolerance and compliance, so that the patient generates minimal adverse reaction and achieves the optimal therapeutic effect.
According to a preferred embodiment, when the processing module 302 performs at least one pressure adjustment within the determined pressure adjustment model, i.e. when the processing module 302 performs a first pressure parameter adjustment of the pressure supply unit 200 based on the pressure adjustment model, the processing module 302 performs a pressure adjustment protocol planning according to the optimal pressure level and duration required by the patient, so that the patient can achieve post-operative compression bandaging after at least one pressure adjustment. Preferably, for the case that the post-operation pressurizing time period required by the patient is far greater than the preset post-operation pressurizing time period, the processing module 302 adjusts the pressure parameter of the pressure supply unit 200 according to the real-time variation of the post-operation pressurizing data, so as to adjust the required pressure parameter according to the real-time variation of the post-operation pressurizing data on the basis of at least one pressure adjustment. Further preferably, the monitoring part 301 can provide supplementary real-time post-operation pressure data for the post-operation pressure data recorded by the processing module 302 and monitored during at least one pressure adjustment in a data interaction manner, so that the processing module 302 can perform fine adjustment of the pressure adjustment scheme according to the real-time post-operation pressure data. Preferably, the processing module 302 pressure times the pressure adjustment according to the determined pressure adjustment scheme over time. After the processing module 302 obtains the real-time post-operation pressure data, the processing module 302 takes the pressure adjustment scheme of at least one pressure adjustment as an initial parameter, and performs planning of the optimized pressure adjustment scheme according to the change of the post-operation pressure data and the pressure timing during the optimized pressure adjustment, so that the post-operation pressure process performed by the patient accords with the change of the disease development process, the individual characteristics and the post-operation characteristic level. Preferably, the optimal pressure adjustment is cross-adjusted in different adjustment schemes based at least on the same pressure parameter to determine the optimal pressure parameter required by the patient. The different adjustment schemes of the same pressure parameter refer to: fine adjustments of different adjustment schemes are made to the same pressure parameter to determine patient recovery at that pressure. Because different pressure measures adopted for different patients lack medical evidence conforming to a linear rule, namely, different pressure measures have different treatment effects on different patients, and the reasons (including psychological reasons and other complex factors) causing the different treatment effects are difficult to judge by the current technical means, the embodiment provides a mode of optimizing pressure adjustment to improve the treatment efficiency of postoperative pressurization, and prevent that the adjustment of pressure parameters cannot be timely carried out after the physical signs of the patients are changed. The preset post-operative compression time period refers to a post-operative compression time period of a normal patient, and can be set by medical staff or can be obtained from a medical database. Preferably, the processing module 302 performs at least one pressure adjustment on the pressure supply unit 200 based on the constructed pressure adjustment model. Preferably, when at least one change feature in the pressure adjustment model constructed by the processing module 302 changes, the processing module 302 optimally adjusts the pressure parameter of the pressure supply unit 200 according to real-time changes of the post-operation pressure data on the basis of at least one pressure adjustment based on the change feature. The change characteristic is, for example, a change in arterial function of the patient. In the case of a primary pressure adjustment of the patient, the patient-related individual sign parameters acquired at this stage are not yet complete, and the adjustment of the pressure supply unit 200 thus performed has not yet reached an optimal level. Taking lymphatic vessel aberration pressure treatment as an example, when the pressure of the patient is adjusted for the first time, the pressure range of the pressure supply unit 200 is 30 mmHg-40 mmHg in combination with the progress of the patient's condition. The processing module 302 evaluates the arterial function of the patient based at least on the real-time data of the arterial of the patient acquired by the monitoring section 301. Based on the change in the evaluation result of the change characteristic, the processing module 302 adjusts the pressure parameter of the pressure supply unit 200. In the case of assessing that the patient's artery is functioning well, the processing module 302 can select a higher pressure level of the pressure supply unit 200, including 40 mmHg to 45 mmHg or more, so that the pressure therapy has a better therapeutic effect on the patient. Specifically, the processing module 302 optimally adjusts the pressure parameter of the pressure supply unit 200 according to the real-time change of the post-operation pressure data on the basis of at least one pressure adjustment based on the change characteristics. The change can also be characterized by clinical stage of edema, degree of tissue fibrosis, site of edema, etc. In the case where lower limb symptoms occur after the anticoagulation treatment of the deep venous thrombosis of the patient's lower limb, the processing module 302 performs at least one pressure adjustment on the pressure supply unit 200 based on the constructed pressure adjustment model. The pressure adjustment is a preliminary pressure adjustment, resulting in a solution that can be used for pressure treatment of the patient at this stage. The pressure parameter is, for example, a pressure of 23 mmHg to 32 mmHg applied to the ankle. The symptoms can be edema of lower extremities, pigmentation, skin nutritional changes, etc. When the patient is diagnosed as a lower limb deep vein thrombosis sequela by performing an ultrasonic examination, the processing module 302 determines that the patient belongs to a patient with a high degree of deep tissue fibrosis, and the processing module 302 optimally adjusts the pressure parameter of the pressure supply unit 200 based on the determined change characteristics on the basis of the initial pressure adjustment. The optimized and adjusted pressure parameter is, for example, a pressure of 34 mmHg-46 mmHg is applied to the ankle. The present embodiment provides a widely used pressure control system that provides a multiple source solution for each treatment session of each patient. The pressure control system promotes local blood circulation by generating continuous or intermittent pressure on the lower limb, thereby alleviating interstitial edema, improving cost effectiveness, increasing patient compliance, and improving therapeutic efficacy. The prior art is unable to address the patient's varying complications and related transformations, such as clinical staging of edema or the extent of tissue fibrosis, etc. Because the physical sign of the patient is continuously changed in the treatment process, a doctor can not realize the real-time and targeted pressure supply adjustment for the change, the treatment period of the patient is prolonged, and even the disease of the patient recurs. In this regard, the present invention enables the pressure parameter provided by the pressure supply unit 200 to conform to the current condition of the patient by introducing one or even more optimal adjustments of the pressure adjustment, thereby shortening the treatment period of the patient and improving the treatment efficiency.
It should be noted that, the at least one pressure adjustment refers to a preliminary adjustment, and is not only capable of characterizing a single adjustment, which may be formed by several pressure adjustments. The optimal adjustment is further adjustment after a plurality of pressure adjustments.
Example 2
This embodiment is a further supplement to embodiment 1, and the repeated contents are not repeated.
The embodiment provides a pressure control system based on a pressure adjustment model, which is used for post-operation gradual pressurization and adjustable pressure.
