Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an intelligent infusion device. Background Art

[0002] Intravenous infusion is the most common nursing operation in clinical practice. According to clinical surveys, in some departments such as gastroenterology, the daily infusion volume of patients in the adult infusion room can be as high as five bottles or more. At present, the common infusion method is that when the bottle of medicine is about to run out or the patient feels uncomfortable with the current infusion speed during the infusion process, the patient presses the call button, and the nurse manually handles it after receiving the call. However, most empty-nest elderly people and young people living alone usually do not have family members to accompany them when they go to the hospital for infusion treatment, and the risk of abnormal infusion events is relatively high. The huge infusion volume has invisibly increased more infusion monitoring work, resulting in nurses having less energy to improve nursing services and skills, which has hindered the development of the nursing industry. The development of an intelligent infusion monitoring and management system can greatly alleviate this problem. Patients can be assured of infusion without accompanying them. Nurses can monitor the infusion situation in the ward, monitor and manage in a unified manner, and accurately handle abnormal situations encountered during infusion, saving rescue time while also improving work efficiency. On the other hand, the industry will have more time and energy to improve nursing services and nursing skills, provide better nursing services, and cultivate more specialist nurses. Therefore, the design of equipment that reduces the burden of infusion for nurses and patients is a major development trend in the medical device industry.

[0003] Patent 202023145183.6 discloses an intelligent infusion device that can automatically adjust the flow rate and automatically change the medicine. The intelligent infusion device can manually control the infusion speed through key interaction, and can also automatically adjust the infusion speed based on the patient's heart rate collected by the ultra-wideband radar module. At the same time, the infusion speed in the infusion tube is detected by the infrared detection module. When the infusion speed is lower than the set infusion speed threshold, the current flow rate control module is turned off and the flow rate control module of the next bottle of liquid is turned on to realize the automatic medicine changing function of the device. However, the automatic medicine changing function is realized by setting multiple flow rate control modules in parallel. Each flow rate control module controls the infusion speed of a bottle of medicine, which is equivalent to setting as many flow rate control modules as there are bottles of medicine. The structure is relatively complicated and the assembly is troublesome. The applicable intravenous infusion device must be a customized infusion device that matches the number of infusion tubes and the number of flow rate control modules. As a disposable medical product, the material cost is too high. Utility Model Content

DETAILED DESCRIPTION

[0023] Combined with reference Figure 1-5 This embodiment provides an intelligent infusion device, including a bracket 1 and a controller module, a wireless network module, a power module, an automatic dressing change module 2, and a speed measurement and regulation module 3 arranged on the bracket 1, and the controller module is electrically connected to the wireless network module, the power module, the automatic dressing change module 2, and the speed measurement and regulation module 3 respectively.

[0024] Specifically, Figure 2 As shown, the automatic dressing changing module 2 includes a top rotating platform 21, a one-way thrust ball bearing 22, a platform driving motor 23, a hollow pillar 24, a sterile patch fixing plate 25, a transmission screw 26, a screw driving motor and a puncture clamp 27. The top rotating platform 21 is cylindrical, and four infusion bottle placement slots 211 are arranged on the top rotating platform 21 at intervals. The four infusion bottle placement slots 211 are evenly distributed around the center line. An opening 213 is provided at the bottom of the infusion bottle placement slot 211 for the infusion bottle mouth to extend out, and a limit spring 215 is provided at the top of the infusion bottle placement slot 211 for pressing against the bottom of the infusion bottle. The limit spring 215 applies elastic force to the infusion bottle 217 in the infusion bottle placement slot 211, which can achieve a better effect of fixing the infusion bottle, and is convenient for placing infusion bottles of different specifications in the infusion bottle placement slot 211, which is highly practical. The automatic dressing changing module 2 is made of stainless steel, which is firm and durable.

[0025] like Figure 5 As shown, the top rotating platform 21 is installed on the top of the hollow pillar 24 through the one-way thrust ball bearing 22, and the bottom of the top rotating platform 21 is fixedly installed on the shaft ring 221 of the one-way thrust ball bearing 22. At the same time, the output shaft of the platform driving motor 23 is fixedly connected to the shaft ring 221 of the one-way thrust ball bearing 22. The output shaft of the platform driving motor 23 rotates to drive the shaft ring 221 to rotate, thereby driving the top rotating platform 21 to rotate. The platform driving motor 23 is a stepping motor, and the platform driving motor 23 is electrically connected to the controller module.

[0026] like Figure 5As shown, the sterile patch fixing plate 25 is used to fix the sterile patch on the mouth of the infusion bottle, and the fixing sleeve is arranged on the outer periphery of the hollow pillar 24. The sterile patch fixing plate 25 is evenly spaced with a plurality of card slots 251. The sterile patch on the mouth of the infusion bottle is fixed in the corresponding card slots 251. When the top rotating platform 21 above is rotated by a certain angle relative to the sterile patch fixing plate 25, the sterile patch on the mouth of the infusion bottle can be torn off.

[0027] like Figure 5 As shown, the transmission screw 26 is arranged in the inner cavity of the hollow pillar 24 and is fixedly connected to the output shaft of the screw drive motor. A through groove 241 is provided on the surface of the hollow pillar 24 along the length direction. The puncture device clamp 27 includes a connecting portion 271 threadedly connected to the transmission screw 26 through the through groove 241 and a main body 273 for fixing the bottle plug puncture device opposite to the infusion bottle. The screw drive motor is a stepping motor. When in use, the bottle plug puncture device of the intravenous infusion device is fixed at the main body 273. The screw drive motor drives the transmission screw 26 to rotate. The connecting portion 271 of the puncture device clamp 27 moves upward or downward with the rotation of the transmission screw 26, thereby driving the puncture device clamp 27 to move upward or downward. When the puncture device clamp 27 moves upward, it drives the bottle plug puncture device to pierce the bottle mouth of the new infusion bottle. When the puncture device clamp 27 moves downward, it drives the bottle plug puncture device to be pulled out from the bottle mouth of the infusion bottle after the infusion is completed.

[0028] A liquid level sensor 28 is installed on the main body 273 of the puncture clamp 27 relative to the infusion bottle mouth. The liquid level sensor 28 is a non-contact capacitive liquid level sensor. When the liquid level at the infusion bottle mouth changes, the capacitance will change. The liquid level sensor 28 is electrically connected to the controller module. When the liquid level is above the liquid level sensor 28, the liquid level sensor 28 outputs a low level. When the liquid level is below the liquid level sensor 28, the liquid level sensor 28 outputs a high level. The liquid level sensor 28 does not need to directly contact the liquid. It only needs to be fixed at a position directly opposite to the lowest position of the liquid level at the bottle mouth as the puncture clamp 27 rises. An opening is reserved at the opening 213 for the liquid level sensor 28 to extend into. The controller module controls the automatic dressing module 2 to automatically change the dressing or control the end of the infusion according to the received sensor signal.

[0029] The speed measurement and regulation module 3 includes an outer box 31, a drip bucket fixing frame 32 and a speed regulator 33. The outer box 31 is fixedly connected to the bottom of the hollow pillar 24, the drip bucket fixing frame 32 is installed on the side of the outer box 31, and a flow rate sensor is installed on the outer box 31 opposite the drip bucket fixing frame 32. The speed regulator 33 includes a shell 331 for the infusion catheter to be inserted, a push block 332 slidably connected to the shell 331 for adjusting the diameter of the infusion catheter, and a speed regulation drive mechanism 333 connected to the push block 332. When in use, the infusion tube is inserted into the shell 331 of the speed regulator 33.

[0030] The Murphy-type dropper of the intravenous infusion set is fixed in the drip bucket fixing frame 32, and a flow rate sensor is installed on the outer box 31 facing the drip bucket fixing frame 32. The flow rate sensor is an infrared radiation sensor. When the infusion starts, the liquid flows into the Murphy-type dropper, and the droplets in the tube drip one by one. The transmitter of the infrared radiation sensor sends an infrared radiation signal. The droplets dripping from the drip bucket fixing frame 32 have a shading effect, and the shading causes the signal to change. After the receiver of the infrared radiation sensor receives the signal, it is transmitted to the controller module for calculating the flow rate. The flow rate sensor and the speed control drive mechanism 333 are electrically connected to the controller module respectively. During the speed adjustment, the stepper motor rotates a specific angle according to the instruction of the controller module, driving the push block 332 to move left and right to squeeze the infusion tube and adjust the diameter of the infusion tube. The speed control drive mechanism 333 is a linear screw stepper motor, which adopts pulse control to achieve precise control of the flow rate.

[0031] In this embodiment, the automatic dressing change module 2 and the speed measuring and regulating module 3 are respectively fixedly connected to the transverse connecting frame 4, and the transverse connecting frame 4 is detachably connected to the bracket 1. The bracket 1 is also provided with an indicator light, an alarm and a storage box 5, and the indicator light and the alarm are respectively electrically connected to the controller module, and can be used for automatic dressing change reminder and needle removal reminder. The storage box 5 is used to place the tablet.

[0032] The intelligent infusion device of this embodiment is suitable for ordinary intravenous infusion sets. When in use, the infusion bottle to be infused is installed in the infusion bottle placement slot 211 and clamped with the limit spring 215, a sterile patch is attached to the bottle mouth of the infusion bottle, and the other end of the sterile patch is fixed on the sterile patch fixing plate 25, the bottle plug puncture of the ordinary intravenous infusion set is fixed on the puncture clamp 27, the Murphy-type dropper is clamped in the drip bucket fixing frame 32, the infusion tube is clamped into the housing 331 of the speed regulator 33, and the flow rate regulator of the ordinary intravenous infusion set is adjusted to the maximum (i.e., it does not work), and then the infusion can be prepared. During the infusion process, the screw drive motor drives the transmission screw 26 to rotate according to the instructions of the controller module, and then drives the puncture device clamp 27 to move downward, so that the bottle stopper puncture device is pulled out from the bottle mouth of the infusion bottle. Since four infusion bottle placement slots 211 are arranged at intervals on the top rotating platform 21, the platform drive motor 23 drives the top rotating platform 21 to rotate 90°, tear off the sterile patch, and then the screw drive motor drives the transmission screw 26 to rotate and drive the puncture device clamp 27 to move upward, so that the bottle stopper puncture device rises to pierce the bottle mouth, and the dressing change is completed.

[0033] In this embodiment, the screw drive motor, controller module, wireless network module, power module, indicator light, alarm, etc. are all installed in the outer box 31. The outer box 31 and the shell 331 and push block 332 of the speed regulator 33 are all made of PVC material to facilitate maintenance and disassembly of the device.

[0034] In this embodiment, the controller module is an STM32F103ZET6 processing chip, and the wireless network module is a LoRa wireless sensor network networking module. The LoRa two-way wireless communication technology has the advantages of long distance, low power consumption, low rate, low cost, strong penetration ability, high communication security, and strong network scalability, and is very suitable for wireless control command transmission of indoor small electronic devices. All data detected in the intelligent infusion device can be transmitted to the intelligent terminal through the wireless network module, and the controller module can communicate with the intelligent terminal through the wireless network module. The intelligent infusion device can support unified monitoring and management of the intelligent terminal.

[0035] The intelligent infusion device of the utility model has an automatic dressing changing module comprising a top rotating platform, a one-way thrust ball bearing, a platform driving motor, a hollow pillar, a sterile patch fixing plate, a transmission screw, a screw driving motor and a puncture device clamp and other structures. The top rotating platform can hold multiple bottles of medicine at the same time. After the bottle stopper puncture device of a common intravenous infusion device is fixed by the puncture device clamp, the bottle stopper puncture device on the puncture device clamp can be pierced into the corresponding medicine bottle on the top rotating platform only by driving the platform driving motor and the screw driving motor. The structure is simple and reliable, easy to use and move, can be directly applied to common intravenous infusion devices, has strong practicality, and has a wider application prospect.
