Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
The breathing machine purchased by the patient is connected with the service platform through the network, the service platform can acquire the operation parameters on the breathing machine and the physiological treatment data when the patient uses the corresponding breathing machine, wherein the operation parameters comprise parameters such as inspiratory pressure and expiratory pressure, and the physiological treatment data comprise blood oxygen, pulse rate, tidal volume, respiratory frequency, minute ventilation volume, air leakage volume and the like. Fig. 1 is a flowchart of a method for adjusting operating parameters of a ventilator according to an embodiment of the present invention. The method is applied to the service platform, and as shown in fig. 1, the method includes the following steps:
101. and obtaining the operating parameters to be adjusted of the used breathing machine according to the past medical history and the physical sign information of the patient, the first physiological treatment data acquired at intervals of first preset time and the first operating parameters of the used breathing machine.
In order to ensure that the treatment effect of the patient can be better and better after the patient uses the ventilator, the operating parameters of the ventilator used, such as the inspiratory pressure and the expiratory pressure of the ventilator, are adjusted at set intervals, and the specific operating parameters of the ventilator are not limited herein.
In addition, before using the ventilator, the past medical history of the patient and the physical sign information are input into the service platform, wherein the physical sign information comprises basic information of personal conditions such as the age, the height and the weight of the patient.
After the patient uses the ventilator, first physiological treatment data and first operating parameters of the ventilator are acquired at a first preset time interval. The first preset time can be set to 3-5 days, if the first preset time is too long, the treatment effect of the patient can be affected, and if the first preset time is too short, the adjustment of the operating parameters of the breathing machine is too frequent, and the use of the patient can also be affected, so that the condition of the patient and the use condition of the patient need to be considered for the setting of the first preset time.
And obtaining the to-be-adjusted operation parameters of the breathing machine by combining the past medical history, the physical sign information, the first physiological treatment data and the first operation parameters of the patient, so that the patient can achieve a better treatment effect through the breathing machine operated by the to-be-adjusted operation parameters.
102. Modifying a first operation parameter of the used breathing machine into the operation parameter to be adjusted;
103. and adjusting the operating parameters of the breathing machine according to the first physiological treatment data, second physiological treatment data acquired at intervals of second preset time and a standard value, wherein the standard value is standard physiological treatment data of the patient acquired according to the past medical history and physical sign information of the patient.
And after the operating parameter of the breathing machine is changed from the first operating parameter to the operating parameter to be adjusted, the treatment effect of the patient is checked at intervals of second preset time.
In addition, physiological treatment statistical data of a patient in a preset time period and operation parameter statistical data of the used breathing machine are obtained, and then safe operation parameters of the used breathing machine are obtained according to the physiological treatment statistical data and the operation parameter statistical data. The acquired physiological treatment statistical data and the acquired operation parameter statistical data of the breathing machine can be close to the real state of an illness of a patient as much as possible by setting the preset time period, so that when the breathing machine treats the patient with the safe operation parameters, the treatment effect of the patient can be ensured not to be deteriorated, and the safe operation parameters can be understood as the safe and conservative operation parameters of the breathing machine.
The standard value is standard physiological treatment data which is obtained in advance according to the past medical history and the physical sign information of the patient and comprises data of blood oxygen, pulse rate, tidal volume, respiratory rate, minute ventilation volume, air leakage and the like. And determining the treatment effect of the patient by using the standard value, wherein the closer the acquired physiological treatment data of the patient is to the corresponding standard value, the better the treatment effect is, and otherwise, the worse the treatment effect is.
For step 103, after the ventilator is set to treat the patient by using the to-be-adjusted operation parameter, second physiological treatment data of the patient is acquired at a second preset time interval, so as to check the treatment effect of the patient. Then, a first difference value between the first physiological treatment data and the standard value and a second difference value between the second physiological treatment data and the standard value are determined, and the operating parameter of the used breathing machine is adjusted according to the comparison result of the first difference value and the second difference value. I.e., the first physiological treatment data is obtained while operating the ventilator under consideration with the first operating parameter, and the second physiological treatment data is obtained while operating the ventilator under consideration with the operating parameter to be adjusted, by comparing the difference between the two and the standard value, the effect of the treatment after using the operating parameter to be adjusted is determined, thereby adjusting the operating parameter of the ventilator under consideration.

The embodiment of the invention solves the problem of long time consumption in the evaluation and judgment process of doctors, reduces the interpretation time of the doctors on patients and improves the diagnosis and treatment efficiency.

207. and when the second difference is larger than or equal to the first difference, adjusting the to-be-adjusted operation parameter of the used breathing machine to be the safe operation parameter.
When the second difference is smaller than the first difference, the obtained second physiological treatment data is closer to the standard value after the used respirator operates according to the operation parameter to be adjusted, namely the treatment effect of the patient is improved after the operation parameter to be adjusted is used, and then the used respirator is controlled to continue to operate according to the operation parameter to be adjusted; on the contrary, when the second difference is greater than or equal to the first difference, which indicates that the second physiological treatment data obtained after the ventilator operates with the operation parameter to be adjusted is far from the standard value compared with the first physiological treatment data, that is, the treatment effect of the patient is not improved after the operation parameter to be adjusted, the operation parameter to be adjusted of the ventilator is adjusted to the safe operation parameter.
