Please refer to FIG. 2 , which is a flow chart of the first embodiment of the method for charging and deflation of the present invention. It should be noted that the charging and deflation method of the present invention is described below with reference to the charging and venting pressure regulating system 10 shown in FIG. 1 , but the invention is not limited thereto. As shown in FIG. 2, the charge and gas pressure regulation method of the present invention includes steps S1 to S4. The various steps of the method are described in detail below:

Step S1: performing an automatic detection of the filling and deflating process, wherein the control unit 13 continuously obtains the instantaneous pressure value of the air bed detected by the pressure detecting unit 12, and instructs the charging and deflating device 10 to discharge any gas tube of the air bed. The gas inside the road.

First of all, the charge and pressure regulating system of the present invention performs an automatic detection of the gas and gas discharge process on the air bed. Before performing the first embodiment of the charge and gas pressure regulation method of the present invention, it is necessary to first connect the air bed and the charge and deflation device 11 to each other to constitute a closed gas passage. The pressure detecting unit 12 disposed in the closed gas passage continuously detects the current pressure of the air bed to continuously obtain the instantaneous pressure value of the air bed and transmits it to the control unit 13. The control unit 13 continues to obtain the instantaneous pressure value of the air bed, and instructs the charging and deflating device 10 to first vent the gas in any gas line of the air bed; that is, the two gas lines are used in the present invention. In the case of an air bed, the control unit 13 instructs the charging and deflating device 10 to first vent the gas in one of the two gas lines according to the setting, and only retains the inflated state in the single gas line (for example, first venting the singular number) The gas in the column airbag retains only the inflated state in the even-numbered airbags; vice versa).

Please refer to FIG. 3 first, which is a detailed flowchart of the automatic detection pressure program of the first embodiment of the deflated gas pressure regulating method of the present invention. As shown in FIG. 3, the automatic detection pressure program of the charge and gas pressure regulation method of the present invention further includes steps S11 to S13. The detailed steps of the automatic detection pressure program will be described in detail below:

Step S11: The two gas lines are inflated by the charge and deflation device 11.

After the air bed and the charging and deflating device 11 are in communication with each other, the two gas lines of the air bed are first inflated by the charging and deflating device 11.

Step S12: It is judged whether each gas pipeline reaches the reference pressure value.

During the inflation process of the deflation device 11, the control unit 13 can continuously obtain the instantaneous pressure value of the air bed by the pressure detecting unit 12 to determine whether the gas lines of the air bed have reached the reference pressure value. Here, the reference pressure value is a pressure comparison standard of the control unit 13, which can also be preset by the control unit 13, or can be set or adjusted by the user as needed to be stored in the memory 133. If the control unit 13 determines that the gas lines of the air bed have reached the reference pressure value, the process proceeds to step S13; otherwise, the process returns to step S11, and continues to be inflated by the charge and deflation device 11 and continues to detect the instantaneous pressure value.

Step S13: venting the gas in any gas line of the air bed by the charging and deflation device 11.

After the control unit 13 determines that the gas lines of the air bed have reached the reference pressure value, the patient can be placed on the air bed to make the air bed in a load state; then the control unit 13 can press the air release device 10 according to the setting instruction. The gas in one of the two gas lines is first vented, leaving only the inflated state in the single gas line.

Step S2: It is determined by the control unit 13 whether the instantaneous pressure value of the air bed in the load state has reached the set pressure value before the set time.

Returning to Fig. 2, next, the control unit 13 determines whether the instantaneous pressure value obtained by the air bed in the single gas line inflated state has reached the set pressure value before the set time. If the instantaneous pressure value has reached the set pressure value before the set time, it indicates that the weight of the patient currently carried by the air bed has exceeded a certain value, so the step S3 is continued; otherwise, the weight of the patient currently carried by the air bed is Within the identifiable range, step S4 is continued.

Step S3: The control unit 13 determines the first charge and deflation strategy of the air bed.

When the control unit 13 determines that the instantaneous pressure value has reached the set pressure value before the set time, the control unit 13 determines the first charge and deflation strategy of the air bed, and instructs the charge and deflation device 11 to perform corresponding inflation or deflation on the air bed. In the present invention, the control unit 13 stores a first parameter table in the memory 133 in advance. The first parameter table indicates a target treatment pressure value corresponding to a plurality of different time intervals and time intervals, and the values are based on After obtaining statistics on the weight and corresponding pressure of a considerable number of patients, it was obtained. In this embodiment, assuming that the reference pressure value is 30 mmHg and the set pressure value is 40 mmHg, the set time may be selected from any time point within a time range, for example, the time range may be 45 to 120 seconds, 60 to 120. Second or other range, and the set time here is preferably 90 seconds, but is not limited to this embodiment. The first parameter list can be illustrated by the following example in Table 1:         <TABLE style="BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; BORDER-COLLAPSE: collapse; BORDER-TOP: medium none; BORDER-RIGHT: medium none; mso-border-alt: double windowtext 1.5pt; Mso-yfti-tbllook: 1184; mso-padding-alt: 0cm 5.4pt 0cm 5.4pt; mso-border-insideh: 1.5pt double windowtext; mso-border-insidev: 1.5pt double windowtext"_0001"MsoTableGrid" border=" 1" cellSpacing="0" cellPadding="0"><TBODY><tr><td> Target treatment pressure value (mmHg) </td><td> 33 </td><td> 37 </td>< Td> 41 </td><td> 43 </td><td> 45 </td></tr><tr><td> time interval (seconds) </td><td> 75~90 </ Td><td> 61~75 </td><td> 51~60 </td><td> 41~50 </td><td> 0~40 </td></tr></TBODY> </TABLE>Table 1       

The first charging and deflation strategy is a time required for the control unit 13 to reach the set pressure according to the instantaneous pressure value, and corresponding to one of the plurality of different time intervals, the difference between the target treatment pressure value and the immediate pressure value corresponding to the time interval is The air bed is inflated or deflated.

Referring to Table 1, for example, assume that the control unit 13 determines that the instantaneous pressure value has reached the set pressure value (40 mmHg) at 55 seconds, that is, the immediate pressure value is before the set time (for example, the aforementioned optimal 90 seconds). The set pressure value has been reached. At this time, the control unit 13 can find that the time interval corresponding to 55 seconds is 51 to 60 seconds according to the first parameter table, and the target treatment pressure value corresponding to the time interval is 41 mmHg. Therefore, the control unit 13 can calculate the difference between the target treatment pressure value and the immediate pressure value (ie, the target treatment pressure value differs from the immediate pressure value by +1 mmHg), and accordingly inflate the air bed to pressurize.

With this design, when the control unit 13 determines that the instantaneous pressure value has reached the set pressure value before the set time, the time point of reaching the set pressure value can be used to find the current air bed by referring to the time adjustment section of the first parameter table. Corresponding to the target treatment pressure value, to inflate or deflate the air bed, without waiting for the set time to arrive, which can effectively reduce the judgment processing time.

Step S4: The control unit 13 determines a second charge and deflation strategy of the air bed.

When the control unit 13 determines that the instantaneous pressure value does not reach the set pressure value before the set time, the control unit 13 determines the second charge and deflation strategy of the air bed, and instructs the charge and deflation device 11 to perform corresponding inflation or deflation on the air bed. In the present invention, the control unit 13 stores in advance a second parameter table in the memory 133. The second parameter table indicates a plurality of different ratios of pressure differences and target treatment pressure values corresponding to the respective differential pressures. It is also based on a considerable number of patients with weight data. In the present embodiment, the same reference pressure value is 30 mmHg, the set pressure value is 40 mmHg, and the set time is preferably 90 seconds. The example of the second parameter table can be as shown in Table 2 below:         <TABLE style="BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; BORDER-COLLAPSE: collapse; BORDER-TOP: medium none; BORDER-RIGHT: medium none; mso-border-alt: double windowtext 1.5pt; Mso-yfti-tbllook: 1184; mso-padding-alt: 0cm 5.4pt 0cm 5.4pt; mso-border-insideh: 1.5pt double windowtext; mso-border-insidev: 1.5pt double windowtext"_0002"MsoTableGrid" border=" 1" cellSpacing="0" cellPadding="0"><TBODY><tr><td> Target treatment pressure value (mmHg) </td><td> 15 </td><td> 18 </td>< Td> 21 </td><td> 25 </td><td> 29 </td></tr><tr><td> Comparison pressure difference</td><td> -8 </td> <td> -6 </td><td> -4 </td><td> -2 </td><td> 0 </td></tr></TBODY></TABLE> Table 2       

The second charging and deflation strategy is that the control unit 13 obtains the pressure difference between the instantaneous pressure value and the reference pressure value according to the instantaneous pressure value reaching the set time, and corresponds to the pressure difference of the plurality of different ratios, and the comparison pressure difference is The air cushion bed is inflated or deflated corresponding to the difference between the target treatment pressure value and the immediate pressure value.

Referring to Table 2, for example, it is assumed that the control unit 13 determines that the instantaneous pressure value (26 mmHg) has not reached the set pressure value (40 mmHg) when the set time (90 seconds) is reached, at which time the control unit 13 can follow the second parameter. The table finds that the pressure difference between the instantaneous pressure value and the reference pressure value (30 mmHg) corresponds to a pressure difference of -4, and the target pressure value corresponding to the pressure difference is 21 mmHg. Therefore, the control unit 13 can calculate the difference between the target treatment pressure value and the immediate pressure value (ie, the target treatment pressure value differs from the immediate pressure value by -9 mmHg), and accordingly, the air bed is deflated to decompress.

With this design, when the control unit 13 determines that the instantaneous pressure value has not reached the set pressure value before the set time, the pressure difference between the instantaneous pressure value and the reference pressure value can be determined according to the pressure adjustment section of the second parameter table. At present, the air bed corresponds to the target treatment pressure value to inflate or deflate the air bed.
