Description

Technical Field

[0001] The present invention relates to the technical field of infusion equipment, and in particular to an infusion drip rate regulating device and system. Background Art

[0002] The infusion drip rate regulator is a device used to control the speed of intravenous infusion. During the medical infusion process, different infusion speeds need to be set according to the age, condition and drug properties of the infusion patient. Therefore, the reasonable setting and accurate adjustment of the infusion speed are crucial.

[0003] For example, when using drugs such as nitroglycerin to relieve angina pectoris, the drip rate may be increased at the beginning to quickly relieve the symptoms and allow the drug to take effect quickly. After the angina symptoms are relieved, the drip rate will be slowed down appropriately to maintain the treatment effect and avoid adverse reactions such as hypotension caused by drug overdose.

[0004] In the prior art, the infusion speed of the infusion bag is usually constant. Every time it needs to be adjusted, whether it is a traditional roller clamp or an electronic infusion pump, manual instructions need to be issued and operated. If medical staff fail to make adjustments in time, the constant infusion speed will cause many adverse reactions to patients. In addition, the existing adjustment device cannot set different speeds according to different time periods. Medical staff often need to set the drip rate of different infusion bags in a specific time period. A large number of infusion bags are not only cumbersome to set, but also increase the workload of medical staff. It is more likely that the infusion speed cannot be adjusted in time, affecting the infusion effect and even causing risks.

[0035] Embodiment 1

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides an infusion drip rate regulating device, comprising: a fixing frame 1; an infusion tube 2, mounted on the fixing frame 1, for conveying liquid materials; a roller clamp 3, located on the fixing frame 1, and configured so that the infusion tube 2 passes through the roller clamp 3, so that the roller clamp 3 regulates the flow rate of the liquid material in the infusion tube 2; an adjusting plate 4, mounted on the fixing frame 1; a sliding plate 5, located on a side of the adjusting plate 4 close to the roller clamp 3 (i.e. Figure 1 The lower side of the middle adjusting plate 4 is slidably connected with the adjusting plate 4, and is configured to cooperate with the roller clamp 3 to adjust the flow rate of the liquid material in the infusion tube 2 when the sliding plate 5 slides on the adjusting plate 4; the driving member 6 is installed on the side wall of the adjusting plate 4, and is used to drive the sliding plate 5 to slide on the adjusting plate 4.

[0037] It should be noted that the roller clamp 3 is a prior art, and generally comprises a clamp and a roller. When the roller slides on the clamp, it continuously squeezes the infusion tube 2 to change the infusion speed in the infusion tube 2 .

[0038] The above device also includes: a microcontroller 7, which is used to transmit information between the modules inside it and control the drive member 6 to operate according to the set requirements. It is installed on one side of the fixing frame 1. Figure 3As shown, the microcontroller 7 includes: a central control module 8, a speed setting module 9, a time monitoring module 10 and a feedback adjustment module 11. The speed setting module 9, the time monitoring module 10 and the feedback adjustment module 11 are all connected to the central control module 8 through electrical signals. In addition, the drive member 6 is also electrically connected to the central control module 8. The central control module 8 is used to transmit information to and from other modules, and to control the opening or closing of the drive member 6. The speed setting module 9 is used to set the infusion speed according to different time periods; the time monitoring module 10 is configured to record the length of time after the infusion speed is adjusted; the feedback adjustment module 11 is configured so that when the time monitoring module 10 records the same time period as that set by the speed setting module 9, the time monitoring module 10 sends a signal to the feedback adjustment module 11, and the feedback adjustment module 11 transmits the signal to the central control module 8 according to the speed set by the speed setting module 9 for the next time period, so that the central control module 8 controls the drive member 6 to operate according to the established requirements.

[0039] It should be noted that the driving member 6 adopts a stepping motor, which can accurately control the angle and number of steps of rotation, and can achieve relatively accurate position control, thereby accurately controlling the infusion dripping rate.

[0040] The microcontroller 7 can use an STM32 series single-chip microcomputer, which can flexibly configure its internal timer and other resources through programming to realize accurate time monitoring function, so as to record the time length after the infusion speed is adjusted. Among them, the STM32 series single-chip microcomputer can specifically adopt the STM32F103X series, etc. At the same time, the PIC series can also be used, which is easy for developers to program functions such as speed setting, time monitoring and feedback adjustment. For example, time-related functions can be realized through its timer module, and control connection with the driver 6 can be realized through the I / O port. Among them, the PIC16F877A series can be used; in addition, the STC89C52 single-chip microcomputer, ATmega16 single-chip microcomputer, ESP32-WROOM-32 single-chip microcomputer, etc. can also be used.

[0041] In order to monitor the infusion flow rate flowing through the infusion tube 2 after the roller clamp 3 adjusts, the microcontroller 7 further includes: a flow sensor 12, which is used to monitor the flow rate in the infusion tube 2. Figure 1 As shown, the flow sensor 12 is installed on one side of the fixing frame 1, connected to the microcontroller 7 through an electrical signal, and is configured so that the liquid material in the infusion tube 2 first passes through the roller clamp 3 area and then passes through the flow sensor 12 area, so that the microcontroller 7 receives the signal of the adjusted flow rate of the infusion tube 2.

[0042] Embodiment 2

[0043] like Figure 4As shown, in order to facilitate the sliding plate 5 to slide better on the adjusting plate 4 and ensure more accurate drip rate adjustment, the infusion drip rate adjustment device in the above embodiment also includes: a first slide groove 13, which is arranged on the side of the adjusting plate 4 close to the roller clamp 3, and is used for the sliding plate 5 to slide on the adjusting plate 4; a second slide groove 14, which is arranged on the side wall of the adjusting plate 4; a small slider 15, which is located in the second slide groove 14 and is connected to the side wall of the sliding plate 5, so that when the small slider 15 slides in the second slide groove 14, it drives the sliding plate 5 to slide in the first slide groove 13; the first slide groove 13 and the second slide groove 14 are connected to each other, so that the sliding plate 5 and the small slider 15 move together.

[0044] In addition, if Figures 4 to 7 As shown, the above-mentioned infusion drip rate adjustment device also includes: a fixed block 16, which is installed on the adjustment plate 4 and is located on the same side as the second slide groove 14; a threaded rod 17, which is threadedly connected to the small slider 15, and one end of the threaded rod 17 is rotatably connected to the fixed block 16, and the other end is connected to the driving member 6, and is configured so that when the driving member 6 drives the threaded rod 17 to rotate, the small slider 15 slides in the second slide groove 14.

[0045] It should be noted that in the infusion drip rate adjustment device, when a stepper motor is used as the driving part 6, the stepper motor is a prior art. Usually, a stepper motor driver is installed inside the stepper motor itself, wherein the stepper motor driver is connected to the microcontroller 7 through an electrical signal, so that the number of steps of its rotation is accurately controlled by the microcontroller 7 to realize the forward or reverse rotation of the threaded rod 17. It can move to any position on the threaded rod 17, and then accurately drive the threaded rod 17 to rotate the corresponding number of circles, drive the small slider 15 to slide a suitable distance in the slide groove, realize the precise adjustment of the position of the sliding plate 5, and finally achieve the purpose of accurately adjusting the flow of the infusion tube 2.

[0046] like Figure 7 As shown, the infusion drip rate regulating device further comprises: two groups of circular grooves 19, which are respectively provided at two ends of the fixing frame 1, so that the infusion tube 2 enters from one group of circular grooves 19 and then passes through the other group of circular grooves 19.

[0047] Embodiment 3

[0048] like Figure 4 As shown, in order to more conveniently squeeze the infusion tube 2 to control the dripping speed, the infusion dripping speed regulating device in the above embodiment further includes: a texture structure 18, which is located on the side of the sliding plate 5 close to the roller clamp 3, and is configured so that when the sliding plate 5 slides in the first slide groove 13, the texture structure 18 cooperates with the roller in the roller clamp 3 to adjust the flow rate of the liquid material in the infusion tube 2. When the roller slides on the clamp, the infusion speed in the infusion tube 2 is continuously changed, and the texture structure 18 is meshed with the gear teeth on the roller, so that when sliding on the sliding plate 5, it can drive the roller to slide, thereby adjusting the infusion speed in the infusion tube 2.

[0049] Embodiment 4

[0050] like Figure 7 As shown, the infusion drip rate regulating device further includes: a key area 20, located on the fixing frame 1, for issuing instructions to the microcontroller 7 to set the time and flow rate.

[0051] like Figure 7 As shown, the infusion drip rate regulating device further includes: a display area 21 located on the fixing frame 1 , for displaying the flow rate in the infusion tube 2 and the content of the instructions in the key area 20 .

[0052] It should be noted that the keypad 20 includes multiple groups of keys, including a switch button, which is used to start the central control module 8 in the standby state; a mode adjustment button, which is used to change the setting of time or speed, and two groups of adjustment buttons, which are used to increase or decrease the speed, and increase or decrease the time setting. For example, the time setting state is entered through the mode adjustment button, and the length of the time period is set through the adjustment button, and then the speed setting state is entered through the mode adjustment button, and the time speed is set through the adjustment button. After completion, the central control module 8 receives the data and makes adjustments, and the next group of time periods and speed settings are performed through the mode adjustment button. At the same time, the microcontroller 7 is installed inside the fixing frame 1, and is connected to the keypad 20 and the display area 21 through wires.

[0053] like Figure 8 As shown, the infusion drip rate regulating device also includes: a conversion module 22, located on the microcontroller 7, for converting the electrical signal transmitted by the flow sensor 12 and the electrical signal transmitted by the key area 20 into a digital signal so that the display area 21 can display it.

[0054] It should be noted that the conversion module 22 receives signals from various input sources, including parameters such as time and flow rate set by medical staff through the keypad 20, and real-time data fed back by various sensors (such as liquid level sensors, physiological parameter monitors, etc.).

[0055] Embodiment 5

[0056] like Fig. 9 As shown, the present invention also provides an infusion drip rate adjustment system, including the infusion drip rate adjustment device of any of the above embodiments and the corresponding preferred embodiments, and also includes: an information terminal 23, which is connected to the microcontroller 7 through electrical signals; a remote control module 24, which is located in the information terminal 23 and is connected to the central control module 8 through electrical signals.

[0057] It should be noted that the information terminal 23 is usually set in a fixed area and is connected to all the infusion drip rate regulating devices of the hospital through electrical signals. Medical staff control each group of infusion drip rate regulating devices through the remote control module 24 in the information terminal 23, send the signal remotely to the microcontroller 7, and then adjust the infusion speed of each group of infusion drip rate regulating devices through the central control module 8 in the microcontroller 7. Based on this, medical staff do not need to inspect each ward one by one, and can control multiple infusion drip rate regulating devices at the same time on the information terminal 23.

[0058] When the technical solution provided by the present invention is implemented:

[0059] The medical staff takes out the infusion tube 2, inserts one end of the infusion tube 2 through one of the circular grooves 19 opened at both ends of the fixing frame 1, then passes the infusion tube 2 through the roller clamp 3 located on the fixing frame 1, ensures that the infusion tube 2 is placed in a position where the roller clamp 3 can be normally adjusted, and finally allows the infusion tube 2 to pass through the circular groove 19 at the other end of the fixing frame 1, and then passes through the flow sensor 12 installed on one side of the fixing frame 1. At this time, the needle is installed at one end of the infusion tube 2, and the other end of the infusion tube 2 is connected to the infusion bottle, thereby completing the installation preparation work of the infusion tube 2 on the device.

[0060] According to factors such as the type of liquid material to be injected, the patient's physical condition and the treatment plan, the infusion speed required in different time periods can be determined, and the key area 20 located on the fixed frame 1 can be directly operated to set the corresponding infusion speed value according to the predetermined different time periods, and at the same time set the infusion time period corresponding to each speed. After receiving the setting instruction, the key area 20 will transmit the relevant electrical signal to the central control module 8 in the microcontroller 7, and the central control module 8 will then send the signal to the speed setting module 9 and the time monitoring module 10 respectively. The central control module 8 will start the driving member 6 installed on the side wall of the adjustment plate 4 in a timely manner according to the time parameters set in the key area 20.

[0061] In addition, the setting can also be made directly through the information terminal 23, and the range to be adjusted can be input into the information terminal 23, and then the remote control module 24 of the information terminal 23 sends an electrical signal to the infusion drip rate adjustment device to be adjusted. After the microcontroller 7 in the infusion drip rate adjustment device receives the electrical signal, it is first sent to the central control module 8, and then adjusted in the above manner.

[0062] After the driving member 6 is started, it will drive the threaded rod 17 connected to it to rotate. Since the threaded rod 17 is threadedly connected to the small slider 15 located in the second slide groove 14, and one end of the threaded rod 17 is rotatably connected to the fixed block 16, when the threaded rod 17 rotates, the small slider 15 will slide in the second slide groove 14. Because the small slider 15 is connected to the side wall of the sliding plate 5, and the first slide groove 13 and the second slide groove 14 are connected to each other, the sliding of the small slider 15 in the second slide groove 14 will drive the sliding plate 5 to slide synchronously in the first slide groove 13 on the side of the adjusting plate 4 close to the roller clamp 3. When the sliding plate 5 slides in the first slide groove 13, the texture structure arranged on the side close to the roller clamp 3 The structure 18 will interact with the roller clamp 3. Through this meshing connection, the roller clamp 3 is driven to adjust the flow rate of the liquid material in the infusion tube 2. After the liquid material in the infusion tube 2 is adjusted by the roller clamp 3, it will continue to flow through the flow sensor 12. The flow sensor 12 can monitor the flow of the infusion tube 2 after adjustment in real time, and transmit the detected flow data to the microcontroller 7 through an electrical signal. The conversion module 22 in the microcontroller 7 will convert the electrical signal transmitted by the flow sensor 12 into a digital signal, and then display it on the display area 21 on the fixed frame 1, so that medical staff can intuitively understand the current flow rate in the infusion tube 2.

[0063] During the infusion process, the time monitoring module 10 in the microcontroller 7 will continue to record the length of time after the infusion speed is adjusted. When the time period recorded by the time monitoring module 10 is the same as the time period set by the speed setting module 9, the time monitoring module 10 will send a signal to the feedback adjustment module 11. After receiving the signal from the time monitoring module 10, the feedback adjustment module 11 will transmit to the central control module 8 according to the speed set by the speed setting module 9 for the next time period. The central control module 8 controls the operation of the driving member 6 again according to the instructions transmitted by the feedback adjustment module 11, thereby re-adjusting the flow rate of the liquid material in the infusion tube 2 according to the steps of the above-mentioned infusion speed adjustment stage, so as to realize the automatic and accurate adjustment of the infusion speed according to the preset different time periods. Through the above complete workflow, the various functions of the infusion drip rate adjustment device can be fully utilized, and efficient, accurate and automatic infusion drip rate adjustment can be realized to ensure the smooth progress of infusion therapy.

[0064] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
