Description
Technical Field
The application relates to the technical field of medical treatment, in particular to a blood pressure measuring method and device.
Background
Blood pressure is the lateral pressure acting on the wall of a blood vessel per unit area when blood flows in the blood vessel, and is the driving force for driving blood to flow in the blood vessel. In different vessels are called arterial blood pressure, capillary blood pressure and venous blood pressure, respectively, and the blood pressure is commonly referred to as arterial blood pressure of the systemic circulation. In brief, blood pressure is the normal blood flow in a blood vessel, and blood is like water and is under pressure since it is a liquid, and the pressure generated by the blood on the blood vessel is the blood pressure.
The most basic vital signs of a human body are heartbeat, respiration and blood pressure, which are basic conditions for judging whether a person is alive or not, and more particularly, when people see a doctor, the most important indicators are the blood pressure which needs to be paid attention to first. Once the blood pressure is reduced, it can be approximately regarded as shock, and if the rescue is not actively carried out, the life is dangerous at any time, and then the blood pressure disappears and the life is ended.
Acute cerebrovascular disease (stroke) is the disease with the highest disability rate of single disease, and the high morbidity, high mortality and high disability rate of the acute cerebrovascular disease cause huge pain and heavy burden to society, families and patients. Although the diagnosis and treatment technology of cerebrovascular diseases has been greatly developed in recent years, and the prognosis of patients is improved to a greater extent, the pathophysiological process of most of patients with cerebral apoplexy cannot be reversed, so the best way for reducing the economic burden of cerebrovascular diseases is prevention, and the first-level prevention, namely early intervention prevention aiming at the risk factors of cerebrovascular diseases, is particularly emphasized, and the occurrence of cerebral apoplexy can be effectively reduced. Research proves that the rising of the incidence rate and the death rate of the cerebral apoplexy is closely related to the rising of the blood pressure, the hypertension is the main risk factor of the cerebral apoplexy, the relation between the blood pressure and the risk of the cerebral apoplexy is continuous, graded, consistent, independent and predictable, and the relation has significance in etiology. The higher the blood pressure is, the higher the risk of cerebral apoplexy is, after other risk factors are controlled, the systolic pressure is 10mmHg higher per liter, and the relative attack risk of cerebral apoplexy is increased by 49 percent; diastolic blood pressure was 5mmHg higher per liter, and stroke was increased by 46% relative risk of morbidity.

In the actual treatment process, the measurement frequency of the blood pressure needs to be adjusted according to different stages of treatment, and the current measurement time of the blood pressure is mainly manually memorized by medical staff. However, the daily workload of the medical care personnel is heavy, it is difficult to accurately remember the measurement time of the blood pressure and adjust the blood pressure measurement interval according to the measurement time, which often causes inaccurate measurement data of the blood pressure and difficulty in guiding subsequent treatment schemes.
According to Chinese acute ischemic stroke diagnosis and treatment guide specifications (2021 years), venous thrombolysis patients need to be monitored and treated in real time, and blood pressure measurement and nerve function evaluation are carried out every 15 minutes during and within 2 hours after venous thrombolysis treatment; then 30 minutes 1 time for 6 hours. Thereafter 1 time per hour until 24 hours after treatment. If the systolic pressure is more than or equal to 180mmHg or the diastolic pressure is more than or equal to 100MmHg, the number of blood pressure monitoring is increased, and the antihypertensive drug is applied for treatment. However, the daily workload of the medical staff is heavy, it is difficult to accurately remember the measurement time and adjust the blood pressure measurement interval according to the measurement time, so that the medical guide specification is difficult to operate effectively. Meanwhile, in the whole diagnosis and treatment process of acute ischemic stroke, the monitor cannot record the start time and the end time of thrombolysis, so that a form corresponding to the thrombolysis process cannot be formed in the blood pressure measurement, the blood pressure measurement record and the thrombolysis process cannot be combined, and the blood pressure change in the thrombolysis process can be well reflected.
The embodiment of the application provides a blood pressure measuring method and device, which can measure blood pressure according to a first measuring period of a first measuring state when a trigger instruction of the first measuring state is received, and measure blood pressure according to a measuring strategy corresponding to a second measuring state when the difference between the duration of measuring blood pressure in the first measuring period and the first measuring duration is smaller than a first threshold. According to the scheme provided by the embodiment of the application, the blood pressure can be automatically and intelligently measured according to the preset measurement strategy (such as the requirement of diagnosis and treatment specifications), the workload of medical workers is reduced, and accurate blood pressure data is provided for the subsequent treatment scheme.
Referring to fig. 1, a possible application scenario diagram provided in the embodiment of the present application includes a blood pressure measuring device and a setting device, where the blood pressure measuring device and the setting device are connected in a wired or wireless manner. In one embodiment, the blood pressure measuring device may be a wearable blood pressure measuring device, and the setting device may be an electronic device such as a mobile terminal, a PC, or the like. In an application scenario, the setting device sends a blood pressure measurement template to the blood pressure measurement device, the blood pressure measurement template comprises at least one measurement strategy in a measurement state, the at least one measurement strategy in the measurement state comprises a measurement strategy in a first measurement state and a measurement strategy in a second measurement state, the measurement strategy in the first measurement state is to measure blood pressure according to a first measurement period corresponding to the first measurement state, and when the difference between the duration of measuring blood pressure in the first measurement period and the first measurement duration is smaller than a first threshold value, the blood pressure is measured according to the measurement strategy corresponding to the second measurement state. After receiving the blood pressure measurement template, the blood pressure measurement device automatically configures according to the measurement strategy of the blood pressure measurement template, so that the measurement strategy of the first measurement state is executed when receiving the trigger instruction of the first measurement state.
In another application scenario, the blood pressure measuring device comprises a setting unit, the setting unit comprises at least one blank template of the blood pressure measuring template, and the medical staff can select and fill in the blank template of one of the blood pressure measuring templates. After completion of the filling, the blood pressure measuring device is automatically configured.
In one embodiment, the blood pressure measurement template comprises the settings of measurement states and measurement strategies of the measurement states, wherein the measurement strategies comprise the settings of a measurement period, a measurement duration and a measurement stage. For example, the blood pressure measurement template comprises a measurement strategy in a first measurement state and a measurement strategy in a second measurement state, the measurement strategy in the first measurement state comprises a measurement period and a measurement duration, the measurement strategy in the second measurement state comprises at least one measurement phase which are arranged in sequence, and each measurement phase comprises a corresponding measurement period and a corresponding measurement duration.
For example, the following:
after the medical staff enters the setting page, a measurement strategy of a first measurement state of thrombolysis start is added, and the measurement strategy of the first measurement state is set to comprise a measurement period of 15 minutes and a measurement time of 2 hours.
After the measurement strategy in the first measurement state is stored, the medical staff adds a measurement strategy of 'thrombolysis is finished' in a second measurement state, and sets the measurement strategy in the second measurement state to comprise 3 measurement stages 1, 2 and 3, wherein the measurement sequence is a measurement stage 1-a measurement stage 2-a measurement stage 3, the measurement period of the measurement stage 1 is '15 minutes', the measurement time is '2 hours', the measurement period of the measurement stage 2 is '30 minutes', the measurement time is '4 hours', the measurement period of the measurement stage 3 is '1 hour', and the measurement time is '18 hours'.
And after the measurement strategy of the second measurement state is stored, the blood pressure measurement template is configured. Each measurement state may or may not be provided with a trigger instruction. In one example, the triggering instruction may be to configure a UI element for each measurement state in the blood pressure measurement template after the measurement policy of each measurement state is saved, so as to automatically generate a virtual key corresponding to each measurement state on an interface of the blood pressure measurement device. In another example, an execution condition is set for each measurement state, a UI element indicating "start/end" is set for a blood pressure measurement template, a virtual key for measurement start/end is automatically generated at an interface of the blood pressure measurement apparatus, and when "start" is clicked, the blood pressure is measured in accordance with the execution condition (e.g., execution time, execution order between the measurement states, etc.) of each measurement state. The embodiment of the application does not limit the content of the configuration strategy of the blood pressure measurement template, and the setting which can be reasonably realized is within the scope of the application.
After the blood pressure measuring device receives a triggering instruction of 'thrombolysis start', the blood pressure measuring device measures the blood pressure with a measuring period of 15 minutes, and after the blood pressure is measured for 2 hours continuously, executes 'thrombolysis end', namely, executes measuring stages 1, 2 and 3 in sequence: firstly, a measuring stage 1 is executed, namely blood pressure is measured by taking 15 minutes as a measuring period, the measuring stage 2 is started after continuous measurement is carried out for 2 hours, namely blood pressure is measured by taking 30 minutes as a measuring period, and a measuring stage 3 is executed after continuous measurement is carried out for 4 hours, namely 1 hour is taken as a measuring period, and measurement is finished after continuous measurement is carried out for 18 hours.
In one example, after the measurement policy of the second measurement state is saved, the medical staff may set a reminding policy: and when the difference between the execution time of the measurement strategy in the first measurement state and the measurement time of the measurement state, namely 2 hours, is less than 1 minute, reminding. The reminding mode can be that an alarm message is sent to a work computer, a nurse station or a mobile terminal of the medical staff.
After the setting is completed, the interface of the blood pressure measuring device can display two operation keys: the two operation keys are used for respectively showing a first measurement state and a second measurement state. When "thrombolysis is started" is clicked, the blood pressure measuring device measures the blood pressure for 15 minutes as a measurement period, and performs a warning when the measurement is continued for 1 hour 59 minutes. After the medical staff receives the warning, click "thrombolysis is ended", then can carry out measurement stage 1, 2, 3 in order: firstly, a measurement stage 1 is executed, namely blood pressure is measured by taking 15 minutes as a measurement period, the measurement stage 2 is started after continuous measurement is carried out for 2 hours, namely blood pressure is measured by taking 30 minutes as the measurement period, a measurement stage 3 is carried out after continuous measurement is carried out for 4 hours, namely measurement is finished after continuous measurement is carried out for 18 hours by taking 1 hour as the measurement period.
In another example, a third measurement state may also be set, where the measurement policy of the third measurement state "receive a diagnosis" includes a measurement period "10" minutes, a measurement duration "stop when receiving a trigger instruction of the first measurement state", and meanwhile, a trigger instruction of the third measurement state is set, that is, a UI element is configured for the third measurement state, so as to display a virtual key "receive a diagnosis" on the interface of the blood pressure measurement device.
In an actual scene, in the whole diagnosis and treatment process of acute ischemic stroke, the monitor cannot record the start time and the end time of thrombolysis, so that a form corresponding to the thrombolysis process cannot be formed in the measurement of blood pressure, the measurement record of blood pressure and the thrombolysis process cannot be combined, and the blood pressure change in the thrombolysis process can be well reflected. In order to solve the problem, in an example, blood pressure and time corresponding to each measurement state are recorded, and the blood pressure measurement record and the thrombolysis process are combined, so that blood pressure changes in the thrombolysis process are well reflected, and data reference is provided for subsequent treatment.
Referring to FIG. 2, a blood pressure measurement method applied to a blood pressure measurement device is provided, and the method shown in FIG. 2 includes 202-204.

In one example, the blood pressure measuring device is a wearable device and is worn on a patient, and a display interface of the blood pressure measuring device comprises two virtual keys of 'thrombolysis start' and 'thrombolysis end'. The first measurement state is thrombolysis start, and when the blood pressure measurement device monitors that thrombolysis start is triggered, the blood pressure of the patient is measured in a first measurement period.
204. And when the triggering condition of the second measurement state is met, measuring the blood pressure according to the measurement strategy corresponding to the second measurement state.
Wherein, the trigger condition of the second measurement state is satisfied, which includes any combination of the following items:

Referring to fig. 3, before receiving a trigger command of the first measurement state, the method further includes:
200. receiving a blood pressure measurement template, wherein the blood pressure measurement template comprises at least one measurement strategy of a measurement state, the at least one measurement strategy of the measurement state comprises a measurement strategy of a first measurement state and a measurement strategy of a second measurement state, the measurement strategy of the first measurement state is to measure blood pressure according to a first measurement period corresponding to the first measurement state, and when a trigger condition of the second measurement state is met, the blood pressure is measured according to the measurement strategy corresponding to the second measurement state;
201. the blood pressure measurement template is configured such that upon receiving a triggering instruction of a first measurement state, a measurement strategy of the first measurement state is executed.
In order to better explain the solutions provided by the embodiments of the present application, the following detailed description is given.
Here, the blood pressure measuring device is a wearable blood pressure measuring device, and a touch screen is arranged on the blood pressure measuring device and can be used for receiving operation commands of medical staff. After entering a setting page of the blood pressure measuring device, the medical staff adds a measuring strategy of 'thrombolysis start' in a first measuring state, and sets the measuring strategy of the first measuring state to comprise a measuring period of '15 minutes' and a measuring time of '2 hours'.
After the measurement strategy in the first measurement state is stored, the medical staff adds a measurement strategy of 'thrombolysis is finished' in a second measurement state, and sets the measurement strategy in the second measurement state to comprise 3 measurement stages 1, 2 and 3, wherein the measurement sequence is a measurement stage 1-a measurement stage 2-a measurement stage 3, the measurement period of the measurement stage 1 is '15 minutes', the measurement time is '2 hours', the measurement period of the measurement stage 2 is '30 minutes', the measurement time is '4 hours', the measurement period of the measurement stage 3 is '1 hour', and the measurement time is '18 hours'.
And after the measurement strategy of the second measurement state is stored, the blood pressure measurement template is configured. Each measurement state may or may not be provided with a trigger instruction. In one example, the triggering instruction may be to configure a UI element for each measurement state in the blood pressure measurement template after the measurement policy of each measurement state is saved, so as to automatically generate a virtual key corresponding to each measurement state on an interface of the blood pressure measurement device. In another example, execution conditions are set for respective measurement states, UI elements indicating "start/end" are set for a blood pressure measurement template, virtual buttons for measurement start/end are automatically generated at an interface of the blood pressure measurement device, and when "start" is clicked, the blood pressure is measured in accordance with the execution conditions (e.g., execution time, execution order between the measurement states, etc.) of the respective measurement states. The embodiment of the application does not limit the content of the configuration strategy of the blood pressure measurement template, and the setting which can be reasonably realized is within the scope of the application.
After the blood pressure measuring device receives a triggering instruction of 'thrombolysis start', the blood pressure measuring device measures the blood pressure with a measuring period of 15 minutes, and after the blood pressure is measured for 2 hours continuously, executes 'thrombolysis end', namely, executes measuring stages 1, 2 and 3 in sequence: firstly, a measurement stage 1 is executed, namely blood pressure is measured by taking 15 minutes as a measurement period, the measurement stage 2 is started after continuous measurement is carried out for 2 hours, namely blood pressure is measured by taking 30 minutes as the measurement period, a measurement stage 3 is carried out after continuous measurement is carried out for 4 hours, namely measurement is finished after continuous measurement is carried out for 18 hours by taking 1 hour as the measurement period.
In one example, after the measurement policy of the second measurement state is saved, the medical staff may set a reminding policy: and when the difference between the execution time of the measurement strategy in the first measurement state and the measurement time of the measurement state, namely 2 hours, is less than 1 minute, reminding. The reminding mode can be that an alarm message is sent to a work computer, a nurse station or a mobile terminal of the medical staff.
After the setting is completed, the interface of the blood pressure measuring device can display two operation keys: the two operation keys are used for respectively showing a first measurement state and a second measurement state.
When the patient arrives at the thrombolysis chamber, such as 10 am, the healthcare worker clicks the "thrombolysis start" button, and the blood pressure measurement device automatically sets the blood pressure measurement period to 15 minutes. When thrombolysis is about to end, e.g. one minute from distance 12. When the medical staff clicks the thrombolysis to finish, the blood pressure is actively set to 15 minutes by taking 12. After 10, the blood pressure measurement interval was 30 minutes, and 18. After 18, the blood pressure measurement period is set again for 1 hour until the end of 12.
The worn blood pressure measuring device can record the time of the first measuring state and the time of the second measuring state, and marks the time on a curve of blood pressure measurement, so that a blood pressure measurement form corresponding to the measuring state and the thrombolysis process is generated, and the blood pressure measurement record and the thrombolysis process are combined, so that the blood pressure change in the thrombolysis process is well reflected.
In one example, a treatment-receiving measurement state can be set before thrombolysis starts, and after the wearable blood pressure measuring device is worn by the patient and the 'treatment-receiving' operation is clicked, the wearable blood pressure measuring device automatically performs blood pressure measurement on the patient at a measurement interval of 10 minutes until thrombolysis starts.
In another example, if systolic blood pressure is detected to exceed 180mmHg throughout the full flow over thrombolysis, the blood pressure measurement interval is automatically set to half, such as automatically modifying the blood pressure measurement interval to 7.5 minutes at the time of the thrombolysis procedure.
In yet another example, the measurement period of the blood pressure is modifiable, such as in a stroke blood pressure management mode, setting the measurement period after admission to 10 minutes, the measurement period in thrombolysis to 15 minutes, the measurement period 2 hours after thrombolysis to 15 minutes, the measurement period 2-6 hours after thrombolysis to 30 minutes, and the measurement period 6 hours later to 1 hour. And then the subsequent medical personnel automatically measure the blood pressure according to the corresponding measurement period after the hospital is started by clicking, the thrombolysis is started and the thrombolysis is finished, and if the measurement period is modified, the time interval during measurement is automatically changed.
In order to further verify the effect of the present application, the inventor makes clinical observations of 30 patients in a certain hospital in beijing by respectively using the inventive example and the traditional blood pressure monitoring mode, and obtains the following series of data comparisons in three aspects of actual implementation, increased workload of medical staff and actual accuracy of quality control tables:
from the above demonstration, it is obvious that the embodiments of the present application have the following advantages:

2. Accurate control and improved medical quality
The interval of measurement control of the blood pressure and the execution time can be executed strictly according to the requirements of the guide, thereby avoiding the possible errors of manual recording, realizing accurate measurement and control, and particularly, after the operation with uncertain time, such as thrombolysis is finished, accurately making an accurate measurement plan according to the diagnosis and treatment state of a patient and executing the accurate measurement plan in place.
3. Form blood pressure data list corresponding to blood pressure measurement record and thrombolysis process
In an actual scene, taking the diagnosis and treatment process of acute ischemic stroke as an example, the monitor cannot record the start time and the end time of thrombolysis, so that a form corresponding to the thrombolysis process cannot be formed in the measurement of blood pressure, and the measurement and the recording of blood pressure and the thrombolysis process cannot be combined, thereby well reflecting the blood pressure change in the thrombolysis process. Through the application, the blood pressure and the time corresponding to each measurement state can be automatically recorded to form an action MARK MARK point, and the blood pressure measurement record and the thrombolysis process are combined, so that the blood pressure change in the thrombolysis process can be well reflected, particularly the blood pressure change along with the MARK action, and data reference is provided for subsequent treatment.
