Therefore, the directional terms used are used to describe and understand the present invention, rather than to limit the present invention.
[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0038] Such as figure 1 As shown, the flowchart of the first embodiment of the pressure adjustment method of the negative pressure treatment device of the present invention is shown, and the method specifically includes:
[0039] Step S10, obtaining the set treatment pressure;
[0040] Step S20: Identify the actual pressure, and calculate the pressure adjustment range according to the treatment pressure;
[0041] In step S30, if the adjustment amplitude is greater than a preset amplitude threshold, a delay adjustment is performed, and the adjustment delay is to adjust the pressure of the negative pressure treatment device according to the preset pressure adjustment rate.
[0042] Such as figure 2 As shown, the flowchart of the second embodiment of the pressure adjustment method of the negative pressure treatment device of the present invention is shown, and the method specifically includes:
[0043] Step S110: Obtain the set treatment pressure. In the embodiment of the present invention, the operator can directly set the treatment pressure value through the operation menu of the negative pressure treatment device 100; or through the function keys, function knobs, etc. of the negative pressure treatment device 100, the treatment pressure can be set.
[0044] In step S210, the actual pressure is identified, and the pressure adjustment range is calculated according to the treatment pressure. In the embodiment of the present invention, the actual pressure value in the liquid collection bottle is obtained by the pressure detection device of the negative pressure treatment device 100; the treatment pressure value can be directly read from the negative pressure treatment device 100. The difference between the treatment pressure and the actual pressure is the pressure adjustment range.
[0045] In step S310, it is determined whether the adjustment range is greater than the preset range threshold, if so, step S311 is performed; otherwise, step S312 is performed. In the embodiment of the present invention, the preset amplitude threshold is a factory setting, or it can be set by the user. The larger the preset amplitude threshold, the faster the pressure change during pressure adjustment; the smaller the preset amplitude threshold, the pressure The slower the pressure changes during adjustment. Those skilled in the art can understand that the operator can set the amplitude threshold according to the needs of different patients.
[0046] In step S311, a delay adjustment is performed, and the delay adjustment is to adjust the pressure of the negative pressure treatment device according to the preset pressure adjustment rate. In the embodiment of the present invention, the preset pressure adjustment rate is a magnitude that controls the pressure value of the negative pressure pump to change a preset amplitude threshold within a specific time. Those skilled in the art can understand that when the adjustment amplitude is greater than the preset amplitude threshold, the working pressure of the negative pressure treatment device 100 will be adjusted according to the preset pressure adjustment rate. The preset pressure adjustment rate changes with the preset amplitude threshold, and the operator can set the amplitude threshold according to the needs of different patients.
[0047] Step S312, directly adjusting the pressure of the negative pressure treatment device is performed. In the embodiment of the present invention, when the adjustment amplitude is not greater than the preset amplitude threshold, the working pressure of the negative pressure treatment device 100 will directly change an adjustment amplitude.
[0048] The embodiment of the present invention may further include:
[0049] In step S410, after the pressure adjustment of the negative pressure treatment device is completed, it is prompted that the pressure adjustment of the negative pressure treatment device is completed. Those skilled in the art can understand that the prompt can be a voice "di" prompt; it can also be a text prompt to exit the pressure adjustment.
[0050] For example, the treatment pressure is 80 mmHg, the actual pressure in the liquid collection bottle acquired by the pressure detection device is 62 mmHg, and the preset amplitude threshold of the negative pressure treatment device 100 is 10 mmHg. The treatment pressure 80mmHg and the actual pressure 62mmHg are identified, and the pressure adjustment range is obtained. The pressure adjustment range is the treatment pressure minus the actual pressure, that is, 80-62=18 mmHg. It is judged whether the adjustment amplitude 18 mmHg is greater than the preset amplitude threshold 10 mmHg, and the judgment result is yes, and the working pressure of the negative pressure treatment device is adjusted according to the preset pressure adjustment rate. Assuming that the preset pressure adjustment rate is 10mmHg/5s, it takes 9s to change the adjustment range to 18mmHg. That is to say, it takes 9 seconds to adjust the time delay to increase the working pressure of the negative pressure treatment equipment from 62 mmHg to 80 mmHg. Among them, the preset amplitude threshold can be set according to the needs of different patients to change the preset pressure adjustment rate.
[0051] Implementing the negative pressure treatment device in the embodiment of the present invention has the following beneficial effects: in the pressure adjustment process, the pressure is slowly increased or decreased according to a preset threshold, reducing the discomfort caused by the sudden increase or decrease of the pressure to the patient ; At the same time, the negative pressure therapy device can also set the threshold by itself according to the different needs of different patients, and change the pressure adjustment rate.
[0052] Correspondingly, the present invention also provides a negative pressure therapy device, see image 3 , image 3 It is a schematic diagram of the structure of a negative pressure treatment device according to an embodiment of the present invention. The negative pressure treatment device 100 specifically includes: a pressure setting unit 110, an analysis unit 120 and a control unit 130; the above units are connected in sequence.
[0053] The pressure input unit 110 is used for the operator to adjust the treatment pressure. In the embodiment of the present invention, the operator can directly set the treatment pressure value through the operation menu of the negative pressure treatment device 100; or through the function keys, function knobs, etc. of the negative pressure treatment device 100, the treatment pressure can be set.
[0054] The analysis unit 120 is used to identify the treatment pressure and the actual pressure, and obtain the pressure adjustment range. In the embodiment of the present invention, the actual pressure value in the liquid collection bottle is obtained by the pressure detection device of the negative pressure treatment device 100; the treatment pressure value can be directly read from the device 100. The difference between the treatment pressure and the actual pressure is the pressure adjustment range.
[0055] The control unit 130 is configured to perform a delay adjustment if the adjustment amplitude is greater than a preset amplitude threshold, where the adjustment delay is to adjust the pressure of the negative pressure treatment device according to the preset pressure adjustment rate. In the embodiment of the present invention, the control unit 130 further includes:
[0056] The determining unit 131 determines whether the adjustment amplitude is greater than the preset amplitude threshold. In the embodiment of the present invention, the preset amplitude threshold is a factory setting, or it can be set by the user. The larger the preset amplitude threshold, the faster the pressure changes during pressure adjustment; the smaller the preset amplitude threshold, the pressure The slower the pressure changes during adjustment. Those skilled in the art can understand that the operator can set the amplitude threshold according to the needs of different patients.
[0057] The first adjustment unit 132 performs delay adjustment when the judgment result of the judgment unit is yes. The delay adjustment is to adjust the pressure of the negative pressure treatment device according to the preset pressure adjustment rate. In the embodiment of the present invention, the preset pressure adjustment rate is a magnitude that controls the pressure value of the negative pressure pump to change a preset amplitude threshold within a specific time. Those skilled in the art can understand that when the adjustment amplitude is greater than the preset amplitude threshold, the working pressure of the negative pressure treatment device 100 will be adjusted according to the preset pressure adjustment rate. The preset pressure adjustment rate changes with the preset amplitude threshold, and the operator can set the amplitude threshold according to the needs of different patients.
[0058] The second adjustment unit 133 is used to directly adjust the pressure of the negative pressure treatment device when the judgment result of the judgment unit is no. In the embodiment of the present invention, when the adjustment amplitude is not greater than the preset amplitude threshold, the working pressure of the negative pressure treatment device 100 will directly change an adjustment amplitude.
[0059] For example, the set treatment pressure is 80 mmHg, the actual pressure in the liquid collection bottle acquired by the pressure detection device is 62 mmHg, and the preset amplitude threshold of the negative pressure treatment device 100 is 10 mmHg. The treatment pressure 80mmHg and the actual pressure 62mmHg are identified, and the pressure adjustment range is obtained. The pressure adjustment range is the treatment pressure minus the actual pressure, that is, 80-62=18 mmHg. It is judged whether the adjustment amplitude 18 mmHg is greater than the preset amplitude threshold 10 mmHg, and the judgment result is yes, and the working pressure of the negative pressure treatment device is adjusted according to the preset pressure adjustment rate. Assuming that the preset pressure adjustment rate is 10mmHg/5s, it takes 9s to change the adjustment range to 18mmHg. That is to say, it takes 9 seconds to adjust the time delay to increase the working pressure of the negative pressure treatment equipment from 62 mmHg to 80 mmHg. Among them, the preset amplitude threshold can be set according to the needs of different patients to change the preset pressure adjustment rate.
[0060] In addition, the negative pressure treatment device 100 in the embodiment of the patent of the present invention may also include a factory setting for the preset amplitude threshold or a threshold preset unit 140 set by the user and a display unit 150 for real-time display of actual pressure.
[0061] The prompt unit 160 is used for prompting that the pressure adjustment of the negative pressure treatment device is completed after the pressure adjustment of the negative pressure treatment device is completed. Those skilled in the art can understand that the prompt can be a voice "di" prompt; it can also be a text prompt to exit the pressure adjustment.
[0062] Implementing the negative pressure treatment device in the embodiment of the present invention has the following beneficial effects: in the pressure adjustment process, the pressure is slowly increased or decreased according to a preset threshold, reducing the discomfort caused by the sudden increase or decrease of the pressure to the patient ; At the same time, the negative pressure therapy device can also set the threshold by itself according to the different needs of different patients, and change the pressure adjustment rate.
[0063] What is disclosed above is only a preferred embodiment of the present invention, which of course cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
