Body weight measuring method for air bed

The present invention relates to a method for measuring body weight for an air bed, and more particularly to a method for providing an air bed for a patient lying down, capable of measuring the weight of a patient by a change in pressure in the air bed.

Acne, also known as pressure sore, is caused by stress or friction that causes skin damage and deep subcutaneous tissue, muscles and bones. Therefore, it is also called pressure ulcer. Patients who are sick in bed for a long time are prone to hemorrhoids because they are not easy to turn over. Therefore, the care of the patient needs to turn over the patient regularly to relieve the pressure on the patient. However, it is very arduous to care for the patient every fifteen minutes to twenty minutes. Moreover, the caregiver cannot turn over for the patient during sleep, so the patient will still have hemorrhoids in the long run. Hemorrhoids usually occur in the heel, vertebrae, scapula, elbow, and hindbrain. It is quite cumbersome to handle, improper treatment, and even cause sepsis.

In order to avoid the occurrence of hemorrhoids in patients who have been lying on the bed for a long time, the conventional technique has designed an air bed to allow the patient to lie in a plurality of air bags.

In order to more clearly describe a method for measuring the weight of an air bed of the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the drawings.

The invention relates to a method for measuring the body weight of an air bed, which can be applied to medical treatment, and has a gas bag which can be filled with gas to avoid or reduce the generation of acne. Please refer to FIG. 1A and FIG. 1B, which are flowcharts of a method for measuring the body weight of an air bed according to the present invention. The invention relates to a method for measuring the body weight of an air bed, comprising the steps of: (S1) having an initial pressure in an air bed; (S2) connecting to a calculation module of the air bed to determine whether to perform measurement, if Step (S3) is performed, if not, step (S1) is performed; (S3) the air bed is inflated to a first pressure; (S4) the air bed is inflated a second pressure; (S5) the air bed is deflated to the first pressure, and the calculation module calculates a deflation time from the second pressure to the first pressure; (S6) the calculation module is in accordance with A measured value control group of the storage device accesses a first measured value corresponding to the deflated time, and simultaneously determines whether to execute a patient lying mode, and if so, performs the step (S8), and if not, performs the step (S7). (S7) the calculation module confirms the number of times, if within the number of times, performs step (S3), if not in the number of times, performs step (S1); (S8) executes the patient lying mode; and (S9) a quantity The measuring module measures a floating pressure in the air bed and transmits it to the computing module; the computing module accesses a predetermined range of floating pressure from the storage device, and determines whether the floating pressure is predetermined at the floating pressure Within the range, if yes, the step (S8) is performed, and if not, the step ends.

Following the above, the initial pressure in the step (S1) may be an arbitrary value, and generally a pressure greater than zero is set to prevent the negative value from affecting the measurement result. In the initial state, no patient is lying on the air bed. At this time, an initial pressure is set as the initial value of the calculated pressure. When a patient is lying on the bed, a pressure difference can be generated to know whether the patient is lying on the air bed. If the measurement results are affected, the pressure difference may not be known accurately. It is impossible to know whether the patient is lying on the air bed or not, and the next body weight measurement is not possible. Therefore, the initial pressure greater than zero is generally set. In step (S2), after the patient lies on the bed, there is a downward force to change the pressure of the air bag in the air bed. At this time, a calculation module can sense the pressure change and judge Whether the body weight measurement can be performed. In the step (S3), the pressure of the air bag in the air bed is first inflated to a first pressure, wherein the first pressure is greater than the initial pressure, and then, in the step (S4), the pressure of the air bag in the air bed is inflated to a second pressure, and then in the step (S5), the calculation module calculates a deflation time from the second pressure deflation to the first pressure, and the deflation time varies depending on the patient's body weight, thereby enabling The weight of the patient is determined; in addition, the difference between the second pressure and the first pressure can be adjusted according to the demand, that is, the pressure value of the first pressure or the pressure value of the second pressure can be adjusted, and the difference is larger, the difference of the deflation time It will also be larger, and vice versa, the best value can be selected according to the calculation requirements for accurate calculation. In the step (S6), the measured value control group is stored in the storage device, and has a plurality of deflation time, and each deflation time corresponds to a first measurement value, so that the calculation module can find according to the deflation time. The first measurement value; the first measurement value may be representative of the patient's weight, or may indicate that the patient is not lying on the bed, when the patient's weight is measured, the patient enters the patient lying mode, and when When a measured value is lower than one standard, it means that the patient may not be lying in bed, maybe it may be detected by mistake in step (S2), or the patient may lie down and then leave the bed. At this time, the patient will not enter the lying mode. And performing the step (S7); in the present invention, the storage device stores a predetermined number of times, and the calculation module confirms the number of steps to enter the step (S7). If the predetermined number of times is exceeded, it indicates that the patient has no patient on the bed. The air bed returns to the initial state, that is, the air bag in the air bed is at the initial pressure, if, if Within the number of times, it is confirmed again; in the present invention, the predetermined number of times can be adjusted and changed as needed.

Following the above, in the present invention, the first stage is inflated to the first pressure and the second stage is inflated to the second pressure, and the deflation time is calculated by deflation to determine the patient's body weight. However, in fact, when implemented, the inflation phase and the deflation phase can be increased according to the demand. In other words, the inflation phase is not limited to the second phase, and the deflation phase is not limited to one phase, for example, three-stage inflation and two-stage deflation. To provide better calculation results. The present invention provides the simplest means of implementation.

It is convenient to replace or modify the whole set of equipment. The measurement module 14 used in the present invention is used to measure the gas pressure, the number of which can be adjusted according to the number of the air bag group 13. The air bag set 13 of the present invention can be divided into at least three groups, one set under the head and the shoulder, one set under the buttocks, and one set under the heel. When implemented, the air bag pressure of each set can be They are adjusted separately to allow the body to withstand the feedback pressure to achieve optimal release. When the number of air bag sets 13 is plural and the single measurement module 14 is difficult to accurately measure the pressure change, it should be adjusted according to the demand. The number of modules 14 is measured to ensure accurate pressure measurements. Further, the mattress 15 used in the present invention must be capable of highlighting the change in the pressure of the air bag group 13, and also capable of transmitting the pressure generated when the patient lies down to the lower side.

Please refer to FIG. 4, which is a flow chart of the detailed steps of the step (S2) of the body weight measuring method of the present invention. As shown in the figure, and referring to FIG. 3 at the same time, the step (S2) of the present invention further comprises the following steps: (S21) whether the measurement module measures the pressure change, and if so, performs the step (S22) and continues the amount. Measure, if not, perform step (S1); and (S22) the calculation module determines that the mattress is subjected to downward pressure, and measures the pressure change according to the measurement module, according to the measured value of the storage The group accesses a second measurement value and performs step (S3). In the step (S22), the third pressure sent by the measurement module 14 to measure the pressure change is transmitted to the calculation module 21, and the calculation module 21 subtracts the initial pressure from the third pressure, and then follows the The measured value of the reservoir is a control group that accesses a second measured value.

Continuing the above, the present invention provides a preliminary method for measuring body weight, which measures the body weight immediately after the patient is lying down. In addition to being a reference value for the second body weight, it can also be confirmed whether someone is lying on the hospital bed. In (S21), the measurement module measures the pressure of the airbag airbag at any time, and when there is a change, the calculation module immediately knows, and according to the change of the pressure, whether the mattress is subjected to downward pressure, That is, if there is a patient lying on the bed, at this time, according to the pressure change, and the weight can be known. If the trachea ruptures, or if the air bag ruptures, it can be detected and reacted immediately. In the present invention, the measured value stored in the storage control group further includes a plurality of pressure change values, each of which corresponds to a second measured value, and the calculation module is found by the measured value control group. The second measurement is representative of the patient's weight. The second measurement can be initially adjusted to immediately change the pressure of the air bag in the air bed for the patient's weight, so that the patient can feel comfortable.

Please refer to FIG. 5, which is a connection diagram of the first embodiment of the air bag set and the air pipe of the present invention. As shown in the figure, in the first embodiment, the air pipe 12 of the present invention is divided into two sets of pipelines, and the two sets of pipelines are staggered and interleaved to provide gas, so that the airbags of the airbag group 13 have the effect of staggering charge and discharge. . Air bag The air bags of group 13 are arranged side by side. When the singular air bags are inflated, the double air bags are deflated. Conversely, when the singular air bags are deflated, the double air bags are inflated, so that the air bed can support the human body, and at the same time appropriately Relieve stress. The most basic function of the patient lying mode provided by the present invention is that the air bag is staggered to fill the gas, so that the pressure exerted by the patient's body can be released to reduce the occurrence of hemorrhoids.

Please refer to FIG. 6 , which is a schematic diagram of the connection of the air bag set and the second embodiment of the air pipe of the present invention. The present invention provides a second embodiment of the air bed, wherein the air tube 12 can also be divided into a first air tube group 121, a second air tube group 122, and a third air tube group 123, and the air bag group 13 can also be Divided into a first air bag group 131, a second air bag group 132, and a third air bag group 133; wherein the second air bag group 132 is disposed in the first air bag group 131 and the third air bag The first air tube 121, the second air tube 122, and the third air tube 123 are respectively connected to the first air bag group 131, the second air bag group 132, and the third air bag group 133; The calculation module 21 can control the flow of gas to the first air bag group 131, the second air bag group 132, and the third air bag group 133, respectively.

Each group of air bags can use a plurality of air tubes. In this embodiment, only one aspect is provided, which is not intended to be limited.

Following the above, in the present invention, each group of air bag sets 13 has a plurality of air bags which are arranged side by side. When implemented, the air bags are staggered with filling gas, that is, when an air bag is filled with gas, the adjacent side air bag It is deflated to achieve the effect of skin pressure release. In the second embodiment, the air bag group 13 is divided into three groups corresponding to the head, the waist, and the heel to adjust the pressure separately in order to accurately control the pressure. When there is a further need to distinguish between more air bag sets 13, it is only necessary to increase the number of sets of air bag sets in accordance with the method of the present invention. The number of sets of air bag sets 13 is not intended to limit the invention.

In addition, the patient lying mode includes timed weight detection. At each specific time, steps (S3) to (S6) are repeated to ensure that the patient is still lying on the bed. If the patient leaves the bed, return to the step. (S1), if the patient is still in bed, continue with the step (S8). If the patient who is sick in bed for a long time changes his or her weight, the patient's lying mode can also be adjusted to change the pressure of the air bag group in the air bed.

Please refer to FIG. 7 , which is a flow chart of the detailed steps of the step ( S9 ) of the body weight measuring method of the present invention. As shown, the step (S9) of the present invention further includes the following steps: (S91) the detecting module measures the floating pressure in the air bed; (S92) the computing module accesses the memory from the memory Floating the predetermined range of pressure, and determining whether the floating pressure is within the predetermined range of the floating pressure, and if so, maintaining the patient lying mode, performing the step (S8), if not, stopping the patient lying mode, and performing the step (S93) (S93) the air bed is charged The detection module measures whether the pressure changes, and if so, performs a step (S94). If not, the computing module issues a hardware abnormality warning; (S94) the computing module issues a notification of leaving the bed, and the step End.

Following the above, in the present invention, in addition to the step (S8) being provided with timing to detect whether the patient has left the bed, the step (S9) also detects whether the patient is lying on the bed in a different manner. Wherein, in the step (S91), the detecting module continuously measures the floating pressure, wherein the floating pressure refers to the pressure in the air bed, and in the step (S92), when the pressure in the air bed changes, the calculation is performed. The module can know through the detection module and determine whether the range of fluctuation of the floating pressure is beyond expectations. The patient may have a turning-over action, either actively turning over or passively turning over. When turning over, it will change the downward force and change the pressure in the air bed. However, the pressure change caused by turning over is not large and must be continuously provided. The patient lies in a lying mode. Therefore, the present invention provides a predetermined range of floating pressure. Within the range, it is determined that the patient may just turn over and still lie on the bed, and the patient lying mode should be continuously provided. Otherwise, the patient is stopped outside the range. The lying mode is performed and the steps are performed (S93). The step (S93) is a confirmation step, because the floating pressure changes beyond the predetermined range of the floating pressure, there may be a patient leaving the bed, or the hardware device may be damaged, for example, the air bag is broken, and therefore, the step (S93) is performed. Action, if the pressure changes after inflation, indicating that the air bag and important hardware components are not damaged, it is determined that the patient is leaving the hospital, and the medical staff is notified to leave the bed according to the step (S94). If the pressure is not changed, the air bag may be broken. Or if the detection component is damaged, it will be hardware. Abnormal warning, notify the staff to come over.

More specifically, in the present invention, when the patient gets up and sits on the bed, the entire downward force is changed, and the air bed can stop the patient lying mode, because the patient has already sat up and there should be no need to relieve the pressure. Therefore, the predetermined range of floating pressure in the reservoir can be set to stop the patient lying mode when the pressure range is less than the pressure in the air bed when the patient is sitting on the bed. Of course, if it is desired to provide the patient lying mode while the patient is sitting, the predetermined range of floating pressure can be changed.

In addition, in the present invention, the first to third pressures in the air bag group refer to the pressure after the voltage is stabilized, and if the pressure is still unstable, the calculation module may have difficulty calculating the difference value.

After the above detailed description, the technology of the present invention has been clearly understood, and the above summary is summarized as follows:

(1) The present invention is capable of calculating a patient's body weight value, and adjusting the pressure of the air bag group in the air bed according to the difference in body weight value, so that the patient can relieve the pressure on the skin and reduce the occurrence of hemorrhoids.

(2) The invention can automatically detect whether the patient has left the hospital bed, or the state of the airbag hardware device of the hospital bed, and issues an instant notification for immediate processing, without the need for continuous human attention, to provide a higher quality air bed.
