[ first embodiment ]

Referring to fig. 1, a first embodiment of the present application provides a patient risk monitoring method based on an operating table, including steps S1 to S4.

Step S1: receiving the working environment information of an operating bed; the operating bed comprises a plurality of compression areas, and the working environment information at least comprises compression force data corresponding to the compression areas.

Step S2: determining a target bearing time threshold corresponding to a target bearing area in the plurality of bearing areas according to the working environment information and preset comparison information;

step S3: acquiring pressure maintenance time corresponding to the target pressure-bearing area according to the working environment information;

step S4: and outputting early warning information when the pressure maintaining time corresponding to the target pressure bearing area reaches a target pressure bearing duration threshold value.

In step S1, a plurality of compression areas of the operating table correspond to respective portions of the patient contacting the operating table, for example, the patient lies on the operating table, the plurality of compression areas of the operating table include a head area, an upper back area, a lower back area, a hip area, a leg area, and the like corresponding to the head of the patient, the plurality of compression areas are divided according to the bed body structure of the operating table, and the operating tables of different structures are classified according to different areas, which is not illustrated in this embodiment. The compression force data corresponding to a compression area can be, for example, distribution data of the compression area subjected to the pressure of a patient, or a maximum pressure value or an average pressure value of the compression area subjected to the pressure of the patient, or information which can be used for representing the compression condition of the compression area, such as the compression level of the compression area.

The target compression region may be any one of the plurality of compression regions, that is, steps S2 to S4 may be performed corresponding to all of the plurality of compression regions. According to the working environment information, the compression state of the target compression area and vital signs of a patient can be digitally embodied, and the method is more visual. The target bearing time period threshold value determined according to the difference of the corresponding bearing force data of different bearing areas in the plurality of bearing areas can be different, and can be the same.

In step S3, the pressure maintaining time corresponding to the target pressure-receiving area refers to the time when the pressure-receiving force data of the target pressure-receiving area is maintained or changed little. Step S3 may specifically include: updating the compression force data corresponding to the target compression area according to a preset period; comparing the updated compression force data with the compression force data before updating; accumulating the pressure maintaining time of the target pressure-bearing area when the difference value between the updated pressure-bearing force data and the pressure-bearing force data before updating is within a preset difference value range; and when the difference value between the updated compression force data and the pre-updated compression force data exceeds a preset difference value range, the pressure maintaining time is reset to zero.

The difference between the updated compression force data and the pre-updated compression force data is the variation of the compression force data, if the variation is within the preset difference range, the compression force data of the target compression area can be considered to be unchanged or changed very little, and the position of the patient corresponding to the target compression area can be considered to be unchanged, so that the accumulated pressure maintaining time is needed. If the variation exceeds the preset difference range, the pressure data of the target pressure receiving area can be considered to be greatly changed, and the position of the part of the patient corresponding to the target pressure receiving area can be considered to be changed, and the pressure before the part is relieved, so that the maintenance time of the current pressure receiving data (namely the updated pressure receiving data) is required to be re-determined after the maintenance time of the pressure is reset to zero. For example, the pre-update compression force is P0, the preset difference range is ±x, and the post-update compression force data (including the end value) between, for example, P0-x and p0+x can be considered as the compression force data of the corresponding target compression region to be kept unchanged or have small variation. And when the updated compression force data is smaller than P0-x or larger than P0+x, the compression force data of the target compression area is considered to be changed greatly, the position of the part of the patient corresponding to the compression area is considered to be changed, and the pressure before the part is relieved.

The target area may be any one of the multiple pressed areas, and the early warning information is output in step S4, that is, when the pressure maintaining time of any one of the multiple pressed areas reaches the target pressure bearing duration threshold. And outputting early warning information when the pressure maintaining time of the plurality of pressure bearing areas reaches the target pressure bearing time threshold value.

For example, the working environment information received in step S1 includes first compression force data of the first compression region, and second compression force data of the second compression region. In step S2, it is determined that the target bearing duration threshold corresponding to the first pressed region is t1, and the target bearing duration threshold corresponding to the second pressed region is t2. In step S3, it is determined that the pressure maintaining time of the first pressure-receiving area is tw1, and the pressure maintaining time of the second pressure-receiving area is tw2. When tw1 reaches t1, the early warning information needs to be output, and when tw2 reaches t2, the early warning information needs to be output, so that the early warning information and the early warning information do not interfere with each other.

When a patient is required to keep the body position required by an operation for a long time passively during the operation, particularly under general anesthesia, the patient loses self-protection reaction, and medical staff cannot intuitively know which parts of the patient have the risk of pressure damage. The early warning information can be displayed by the early warning information control display unit or the alarm unit alarms in a sounding or luminous mode, and prompts are sent to medical staff, so that the medical staff can timely learn the states of all parts of a patient according to the prompts corresponding to the early warning information, and even if corresponding measures are taken, the risk of pressure injury or other complications of the patient due to the fact that the patient is in a specific body position for a long time is reduced.

The early warning information comprises, for example, area position information of the target compression area, so that the controllable display unit can display the area position information of the target compression area, and the like, and the medical staff can directly adjust the body position of the part of the patient in the target compression area according to the area position information. The operation is more convenient.

In some embodiments, the predetermined comparison information is a function of the magnitude of the compression force (i.e., the pressure level) as a function of the maximum compression time. Referring to fig. 2, the ordinate of any point in the function in fig. 2 is the magnitude of the compression force, and the abscissa is the maximum compression time corresponding to the magnitude of the compression force. For example, the pressure level of the first pressure-bearing area is a level, and when the first pressure-bearing area is maintained at the a level for d minutes, early warning information is output. Or if the pressure level of the second pressure-bearing area is b-level, outputting early warning information after the second pressure-bearing area is maintained at b-level for e minutes.

In other embodiments, the predetermined control information is a function of the maintenance time of the prescribed compression force as a function of the degree of patient damage. For example, referring to fig. 3, the abscissa of any point in the function of fig. 3 is the maintenance time of a given compression force, and the ordinate is the patient's injury level corresponding to the maintenance time, e.g., the patient's injury level increases more slowly with time in the period a of fig. 3, and more rapidly with time after the period b is reached. Therefore, the corresponding target bearing time threshold value can be determined according to the damage degree of the patient, and the hand damage degree of the patient is ensured to be lower. The preset control information comprises various compression forces as a function of the maintenance time of the specified compression force and the damage degree of the patient.

More specifically, the target bearing time period threshold includes a first target threshold and a second target threshold, the first target threshold being less than the second target threshold; the outputting the early warning information when the pressure maintaining time corresponding to the target pressure bearing area reaches a target pressure bearing duration threshold value comprises the following steps: and outputting first early warning information when the pressure maintaining time corresponding to the target pressed area reaches the first target threshold value, and outputting second early warning information when the pressure maintaining time corresponding to the target pressed area reaches the second target threshold value, wherein the second early warning information is different from the first early warning information. For example, when the functional relationship between the maintaining time of the compression force corresponding to the compression force of the target compression area and the damage degree of the patient is shown in fig. 3, the first target threshold may be T1, the second target threshold may be T2, and when the pressure maintaining time corresponding to the target compression area reaches T1, the first early warning information is output, where the first early warning information is applied to a milder alarm for reminding the medical staff. And outputting second early warning information when the pressure maintaining time corresponding to the target pressure-bearing area reaches T2, wherein the second early warning information is used for warning medical staff in a relatively urgent manner. The first early warning information and the second early warning information are different, so that medical staff can acquire different conditions of a patient at different stages. In actual operation, for example, when the pressure maintenance time reaches T1, the operation is at a key node, the whole position of the patient cannot be adjusted, at this time, medical staff can know that the pressed time of the patient is longer and the whole position is required to be adjusted but is temporarily not adjusted, and when the pressure maintenance time reaches T2, the position of the patient is adjusted after receiving the corresponding prompt of the second early warning information.

In some embodiments, the operating environment information of the operating table may also include vital sign parameters of the patient, such as patient skin temperature, patient partial pressure of transcutaneous oxygen (TcPO 2), and patient partial pressure of transcutaneous carbon dioxide (TcPCO 2), among others. The pre-warning information may also include vital sign parameters of the patient, and may include a combination of one or more of these. Clinical experiments show that the pressure of normal skin capillary vessels is 2.1-4.4 kPa, and the pressure exceeds the pressure, so that the blood flow perfusion of the capillary vessels to tissues can be blocked, and the hypoxia of the tissues is caused. If the pressure is longer than 10.74kPa (more than 3 times the average pressure of capillary vessels), the tissue circulation is blocked, the superficial tissue is not sufficiently supplied with blood for a long time, and the tissue destruction and pressure ulcer are caused. Through experiments, human tissues are possibly damaged under the pressure of 3.99 kPa. Without protective measures, the human tissue is subjected to a pressure of 4.67kPa for 4 hours without changing the posture, while if the pressure is increased to 9.33kPa, the safety time is shortened to 2 hours. By using TcPCO2 and TcPO2 technical parameters, tcPO2CV is calculated, when the pressure is more than or equal to 70mmHg and the duration is more than or equal to 2 hours or the TcPO2CV is more than or equal to 20 percent, the TcPO2 variation coefficient (coefficient of variation, CV) is a variable independent risk factor for judging the microcirculation of human tissues, and the potential complication possibility of the perioperative period is early warned by combining the physical characteristic technical parameters. Therefore, the embodiment combines vital sign parameters of various patients for better reference by medical staff.

In some embodiments, the method further includes step S5, where the control display unit displays the working environment information of the operating table, for example, the control display unit displays a cloud chart of pressure distribution of a plurality of pressure areas, a patient body temperature, a patient percutaneous oxygen partial pressure, a patient percutaneous carbon dioxide partial pressure, etc., and after outputting the early warning information, the medical staff receives the alarm and can determine whether to adjust the body position of the patient corresponding to the target pressure area according to the displayed working environment information in combination with actual conditions or clinical experience.
