Wherein the temperature device 195-9 provides a user interface to the setting of the temperature of the fluid in the heated infusion set.

In some embodiments of the present invention, the user may set the infusion rate at the time of infusion by the infusion pump 100, including but not limited to entering the corresponding infusion rate on the display screen 160 or setting the infusion rate by a key on the infusion pump 100. The infusion pump 100 can obtain the set infusion rate through the input interface connected to the display screen 160 and the keys. In this embodiment, the infusion pump 100 determines the infusion rate set by the user and controls the driving mechanism 118 to move at the corresponding initial motor speed, and drives the pump blade 114 to press the infusion set 30 so as to make the fluid in the infusion set 30 flow at the set infusion rate.

In one embodiment, the brand of the infusion set and the specification of the infusion set corresponding to each brand are different, and thus different types of infusion sets 30 exist. For example, the infusion sets 30 of different types may have different diameters, manufacturing materials, and elasticity of the tubing, which may cause the flow rates of the liquids in the infusion sets 30 to be different when the infusion pumps 100 are operated at the same motor speed, thereby affecting the infusion accuracy of the infusion pumps. In this embodiment, the infusion pump 100 includes calibration coefficients corresponding to different types of infusion sets. When the user sets the infusion speed, the user may set the type corresponding to the infusion set 30, and thus, when the infusion pump 100 obtains the infusion speed and the infusion set type set by the user, the infusion pump selects the calibration coefficient corresponding to the set infusion set type to calibrate the infusion speed. The infusion pump 100 may control the initial motor speed of the drive mechanism 118 based on the calibrated infusion rate such that the flow rate of the fluid in the calibrated infusion set 30 corresponds to the set infusion rate.

In the present embodiment, after the user sets the infusion speed, the infusion device 30 may be fatigued due to an increase in the infusion time of the infusion device. Therefore, the infusion pump 100 can compensate the motor rotation speed of the driving mechanism 118 according to the accumulated infusion time or the accumulated infusion amount of the infusion set 30, so as to adjust the motor rotation speed of the driving mechanism 118, and the flow rate of the liquid in the infusion set 30 when the driving mechanism 118 operates at the adjusted motor rotation speed is also consistent with the infusion speed set by the user.

In one embodiment, the infusion pump 100 may include a timer, wherein the timer is configured to start timing when the infusion pump 100 controls the flow of fluid in the infusion set 30 or when the user presses down to start operation after setting the infusion speed and the infusion set type, and the timer starts timing and generates timing information corresponding to the infusion time in real time. The infusion pump 100 counts the accumulated infusion time of the infusion set 30 based on the timing information so that the infusion pump 100 adjusts the motor speed of the drive mechanism 118 based on the accumulated infusion time. While the timer counts the accumulated infusion time of the infusion set 30, the infusion pump 100 is also used to count the accumulated infusion volume of the infusion set 30. In this embodiment, the infusion pump 100 may count the accumulated infusion amount of the infusion set 30 in the range corresponding to the timing information of the timer according to the drop number sensor 132, or calculate the accumulated infusion amount of the infusion set 30 according to the set infusion flow rate and infusion time.

In this embodiment, when the opening and closing state of the pump door 119 is changed, or the in-place state of the infusion set 30 in the infusion line mounting groove 115 is changed, or the displacement state of the infusion line mounting groove 115 in the infusion set 30 is changed, the infusion pump 100 may reset the accumulated characteristic value of the infusion set 30. For example, the infusion pump 100 may reset the accumulated infusion time and the accumulated infusion amount to 0 when a preset event is detected from the position sensor 164 that the pump door 199 of the infusion pump 100 changes from a closed state to an open state. Alternatively, infusion pump 100 may reset the accumulated infusion time and the accumulated infusion amount to 0 when a predetermined event of displacement of infusion set 30 on infusion line mounting slot 115 is detected based on displacement sensor 166. Alternatively, the infusion pump 100 may reset the accumulated infusion time and the accumulated infusion amount to 0 when the pressure sensor 136 detects that the infusion set 30 is detached from the infusion line mounting groove 115 and then mounted on the infusion line mounting groove 115.

And 102, adjusting the working state of the driving mechanism for multiple times according to the accumulated characteristic value.

Referring also to FIG. 5, a flowchart illustrating an embodiment of step 102 of FIG. 1 is shown. In this embodiment, in order to reduce the shortage of the decrease in the infusion accuracy due to the fatigue of the infusion set, the infusion pump 100 may adjust the operating state of the drive mechanism based on the accumulated characteristic value.

And 200, determining a plurality of compensation information according to the accumulated characteristic value.

In this embodiment, each accumulated characteristic value X may correspond to one compensation information Coef, so that the infusion apparatus 30 may determine the multiple compensation information Coef corresponding to the continuously increased accumulated characteristic values as the accumulated characteristic values are continuously increased during the infusion process.

In one embodiment, the infusion pump 100 may compare the determined cumulative characteristic value to a predetermined threshold value to determine a relationship between the cumulative characteristic value and the predetermined threshold value. When the accumulated characteristic value is less than the preset threshold value, the infusion pump 100 may determine first compensation information; when the accumulated characteristic value is equal to the preset threshold value, the infusion pump 100 may determine second compensation information; when the accumulated characteristic value is greater than the preset threshold, the infusion pump 100 may determine third compensation information, wherein the first compensation information is less than the second compensation information, and the second compensation information is less than the third compensation information. In this manner, the infusion pump 100 may control the motor speed of the drive mechanism 118 based on a plurality of compensation information.

In an embodiment, when the accumulated characteristic values are different, the preset threshold may also be different, for example, when the accumulated characteristic value is the accumulated infusion time, the preset threshold may be a first preset threshold; when the accumulated characteristic value is the accumulated infusion amount, the preset threshold may be a second preset threshold. The predetermined threshold may also be related to the type of infusion set 30.

Step 202, determining a plurality of compensation flow rates according to the plurality of compensation information and the infusion speed.

When the infusion rate set by the user is r, the infusion pump 100 may determine a compensated flow rate B according to the compensation information and the infusion rate, wherein the compensated flow rate B may be represented as:

b ═ r ═ (1+ Coef) formula (1)

For example, when the accumulated characteristic values are X1, X2, and X3, respectively, the corresponding compensation information is Coef1, Coef2, and Coef3, so that the infusion pump 100 determines a plurality of compensation flow rates as follows:

B1＝r*(1+Coef1)、B2＝r*(1+Coef2)、B3＝r*(1+Coef3)。

in addition, the above formula (1) can also be expressed as:

B＝r+r*Coef

where r × Coef represents an adjustment increment, i.e., the infusion pump 100 can control the motor speed of the drive mechanism 118 based on the adjustment increment when the infusion rate r is determined.

And 204, adjusting the motor rotating speed of the driving mechanism according to the plurality of compensation flow rates.

After determining the plurality of compensated flow rates, infusion pump 100 may adjust the motor speed of drive mechanism 118 based on the compensated flow rates. When the infusion pump 100 adjusts the driving mechanism 118 according to a plurality of compensated flow rates, the motor rotation speeds of the driving mechanism 118 may be different, and the flow rates of the liquid in the infusion set 30 are the same when the driving mechanism 118 drives the pressing mechanism 113 to press the infusion set 30, and the infusion speed set by the user can be achieved. In this embodiment, after the driving mechanism 118 is adjusted according to the plurality of compensated flow rates, the flow rate of the infusion set 30 displayed on the display screen 160 is the infusion rate set by the user even if the rotation speed of the motor of the driving mechanism 118 changes.

In this embodiment, the accumulated characteristic value includes accumulated infusion time and accumulated infusion volume. The recovery capability of the infusion set after extrusion is related to the characteristics of materials used for manufacturing the infusion set, the mixing ratio of different materials, the diameter of an infusion set pipeline, the wall thickness of the infusion set and the like. Therefore, the value of the compensation information Coef is not only related to the accumulated characteristic value, but also possibly related to the category of the infusion set. For example, for infusion sets of the same category, as the cumulative characteristic value increases, the value of the compensation information also increases, and the cumulative characteristic value and the value of the compensation information are in a forward relationship, wherein the forward relationship may be linear, nonlinear, continuous, or discontinuous. For infusion sets of different categories, the values of the corresponding compensation information under the same accumulated characteristic value can be the same or different.

Fig. 6 is a schematic diagram showing the relationship between the accumulated infusion time and the compensation factor of infusion sets of different types according to an embodiment of the present application. In this embodiment, the value of compensation information Coef can be expressed as a compensation coefficient, which is a percentage, and the compensation information Coef is related to the accumulated infusion time, the set infusion speed, and the adjustment coefficient, which can be expressed as:

Coef(r，t)＝a×(t×f(r))^bformula (2);

wherein t is the accumulated infusion time, r is the infusion speed, r₀The infusion set is a normalization factor of the infusion speed, f (r) is an accumulated infusion time adjustment coefficient, the adjustment coefficient changes along with the infusion speed r, c is an influence factor of the infusion speed on the accumulated infusion time adjustment coefficient, a and b are a compensation coefficient 1 and a compensation coefficient 2 corresponding to the infusion precision related to the infusion set type such as the brand and the specification of the infusion set, wherein the compensation coefficient 1 and the compensation coefficient 2 can be determined through an infusion precision measurement experiment.

Coef (r, t) in equation (2) above may also be replaced with other functions, including but not limited to a one-term power function or a sum of multiple term power functions. f (r) other functions may be used instead, such as other linear functions, curvilinear functions, piecewise linear functions, piecewise curvilinear functions, and the like.

In this embodiment, when the infusion speed of the infusion pump 100 is lower than the preset speed, f (r) may be set to 1, and at this time, the formula (2) may be expressed as:

Coef(t)＝a×t^bformula (4)

As shown in fig. 6, it includes a relationship diagram of the accumulated infusion time and the compensation factor of the infusion set type 1 and the infusion set type 2, wherein the horizontal axis represents the accumulated infusion time in hours; the vertical axis represents the compensation coefficient. As the accumulated infusion time increases, the compensation factor for each type of infusion set increases, and as can be seen from equation (1), as the compensation factor increases, the compensation flow rate increases accordingly, and as a result, as the accumulated infusion time increases, the motor speed of the control drive mechanism 118 also increases accordingly for the infusion pump 100.

As can be seen from fig. 6, the slopes of the curves corresponding to the infusion apparatus type 1 or the infusion apparatus type 2 are gradually decreased, that is, the ratio (slope) between the change value of the compensation coefficient and the change value of the accumulated infusion time is in an inverse relationship with the accumulated infusion time; as the accumulated infusion time increases, the ratio (slope) of the change value of the compensation coefficient to the change value of the accumulated infusion time gradually decreases.

Fig. 7 is a schematic diagram illustrating a relationship between an accumulated infusion time and a compensation factor of an infusion apparatus when the rotational speed of the motor of the driving mechanism is adjusted at intervals of a predetermined time according to an embodiment of the present application. To reduce the need to frequently adjust the motor speed of the drive mechanism, the infusion pump 100 may switch or adjust the motor speed of the drive mechanism at predetermined intervals.

For example, for infusion set category 1, when the accumulated infusion time reaches Ta, the infusion set 100 may determine the compensated flow rate according to the first compensation coefficient v1 and determine the corresponding first motor rotation speed; when the accumulated transfusion time reaches Tb, the transfusion device 100 can determine the compensation flow rate according to the second compensation coefficient v2 and determine the corresponding second motor rotation speed; when the accumulated infusion time reaches Tc, the infusion set 100 may determine the compensated flow rate according to the third compensation factor v3, and determine a corresponding third motor rotation speed. As can be seen from fig. 7, a first slope between the first motor rotation speed and the second motor rotation speed is different from a second slope between the second motor rotation speed and the third motor rotation speed, and the first slope is greater than the second slope. Wherein the first slope may be expressed as: (v2-v1)/(Tb-Ta), the second slope may be expressed as: (v3-v 2)/(Tc-Tb). In this embodiment, the predetermined time intervals may be equal or unequal; the predetermined time interval may also be related to the type of infusion set.

Please refer to fig. 8, which is a schematic diagram illustrating a relationship between the accumulated infusion amount and the compensation factor of the infusion apparatus at different infusion speeds according to an embodiment of the present application, wherein the horizontal axis represents the accumulated infusion amount in liters; the vertical axis represents the compensation coefficient. In this embodiment, the value of compensation information Coef can be expressed as a compensation coefficient, which is a percentage, and the compensation information Coef is related to the accumulated infusion amount, the set infusion speed, and the infusion apparatus type, which can be expressed as:

Coef(r，vol)＝a(r)×vol^b(r)formula (5)

Wherein vol is the accumulated infusion amount, r is the infusion rate, and a (r), b (r) are the

compensation factors

3 and 4 of the infusion precision related to the brand, specification and infusion rate of the infusion set. For the infusion apparatus with a specific brand and specification, the compensation coefficient 3 and the compensation coefficient 4 can also be determined by long-time infusion precision measurement experiments at different infusion speeds. The above equation (5) Coef (r, vol) can also be replaced with other functions, including but not limited to a one-term power function or a sum of multiple-term power functions.

After the brand and specification of the infusion set are selected, the infusion precision compensation coefficients a (r) and b (r) of the infusion set are related to the infusion speed r. When the infusion speed of the infusion pump is lower than a certain speed r₁When a (r) is approximately equal to a₁，b(r)≈b₁Formula (5) is simplified to formula (6); the infusion speed of the infusion pump is not lower than a certain speed r₁And below a certain speed r₂When a (r) is approximately equal to a₂，b(r)≈b₂Equation (5) is simplified to equation (7). The a (r), the b (r) and the r can be fitted in a segmented mode according to the transfusion speed r or in other modes.

As shown in fig. 8, when the infusion speed is different, the compensation coefficient determined by the infusion pump 100 according to the accumulated infusion amount may be different. When the accumulated infusion amount increases, the compensation coefficient corresponding to each infusion speed increases, and according to the formula (1), the compensation flow rate increases correspondingly when the compensation coefficient increases, so that the rotation speed of the motor of the control driving mechanism 118 also increases correspondingly when the accumulated infusion amount increases by the infusion pump 100. As can be seen from fig. 8, the slope of the curve corresponding to different infusion speeds gradually decreases, i.e. the ratio of the change value of the compensation coefficient to the change value of the accumulated infusion volume (i.e. the slope) has an inverse relationship with the accumulated infusion volume; as the cumulative amount of infusion increases, the ratio (i.e., the slope) of the change value of the compensation coefficient to the change value of the cumulative amount of infusion gradually decreases.

In an embodiment, the infusion pump 100 may also determine the accumulated infusion amount at preset intervals, and switch the motor speed of the driving mechanism according to the determined accumulated infusion amount, which is similar to the motor speed of the driving mechanism determined at preset intervals in the above embodiment, and therefore, the description thereof is omitted here. In one embodiment, when the infusion pump 100 reaches a maximum threshold value based on the compensation factor determined by the accumulated characteristic value, the infusion pump 100 may control the driving mechanism to maintain operation at a maximum motor speed and/or may indicate, acoustically, optically, by way of a message, etc., that the current infusion set is being used for an extended period of time. In one embodiment, the infusion pump 100 may store the corresponding relationship between the accumulated characteristic value and the compensation coefficient as a compensation scheme in the memory 104, and thus, each category of infusion set may have a compensation scheme correspondingly set. When the infusion pump 100 determines the infusion set type information set by the user via the input interface, the infusion pump 100 may select a corresponding compensation scheme from the memory 104 according to the infusion set type information set by the user and adjust the operating state of the drive mechanism 118 according to the selected compensation scheme. In one embodiment, the compensation scheme may also be associated with a set infusion rate, i.e., the memory 104 of the infusion pump 100 stores compensation schemes corresponding to different infusion rates, so that the infusion pump 100 may determine a corresponding compensation scheme according to the type of the infusion set 100 and the set infusion rate set by the user, and adjust the operating state of the driving mechanism 118 according to the determined compensation scheme.

The infusion control method controls the motor rotating speed of the driving mechanism according to the accumulated characteristic value and the infusion speed, so that the motor rotating speed of the driving mechanism can be timely adjusted when the infusion set infuses, the infusion speed of the infusion set after adjustment is consistent with the infusion speed set by a user, and the influence of infusion precision reduction caused by long-time infusion of the infusion set is reduced.

In one embodiment, the memory 102 is used to store the computer programs and/or modules, and the processor 150 implements the various functions of the infusion control method by running or executing the computer programs and/or modules stored in the memory device 102 and invoking data stored in the memory device 102. The storage device 102 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function, and the like. In addition, the storage device 102 may include a high speed random access memory device, and may also include a non-volatile storage device such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), at least one piece of magnetic disk storage, a Flash memory device, or other volatile solid state storage.
