Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical related technologies, and in particular to a medical intelligent infusion device. Background Art
[0002] In modern work and life, people's high-intensity work and unhealthy work and rest habits will affect their immunity, and the incidence of colds and fevers will become higher and higher. When people have colds and fevers, they often receive infusions. Intravenous infusion is a very common and widely used treatment method in clinical practice. The principle of traditional intravenous infusion is to use the physical principle of liquid static pressure and atmospheric pressure to infuse liquid into human veins. The liquid in the infusion bag is affected by atmospheric pressure, causing the liquid to flow into the rubber tube to form a water column. When the water column pressure is greater than the venous pressure, the liquid in the bottle flows smoothly into the vein.
[0003] Some infusion devices currently in use basically require manual adjustment of the infusion height to ensure that the infusion flows at a normal speed. During the infusion process, medical staff needs to be called to change the water. This method is not only cumbersome and inconvenient to operate, but also unsafe. Due to the long infusion time, it is difficult for patients to keep an eye on the infusion process. If medical staff cannot be called to change the water in time, once the time is missed, blood reflux may occur, causing other dangers. At the same time, during the long infusion process, if the patient is not careful, the arm at the infusion end may move up and down over a large range, which may easily affect the height difference between the infusion bag and the intravenous infusion position, thereby causing the infusion to be too slow or blood reflux, affecting normal infusion.

[0019] The present invention has the following advantages: when in use, medical personnel place the medicine bags that need to be infused in the limiting rings respectively, and the active column will be driven downward by the gravity of the infusion bag itself, and the active column will drive the connecting rod downward, and at the same time, the medical personnel will insert the needle tube into the infusion port of the infusion bag. In the initial state, the blocking rod is under the action of the limiting sleeve, and its bottom end is above the water guide tube at the bottom of the liquid guide tube. Therefore, the infusion is carried out from the leftmost infusion bag first, and the liquid flows into the transition tube through the collecting pipe. The floating plate in the transition tube will drive the monitoring rod to rise a distance under the action of the liquid, and then the liquid enters the heating box through the folding tube. When the weather temperature is low, the medical personnel can start The electric heating rod heats the liquid in the folding tube to make the infusion more comfortable. The liquid eventually enters the patient's vein through the infusion tube. At this time, the fan and air pump are started, and the medical staff can leave. The device performs normal infusion. When the infusion of the first infusion bag is completed, the weight of the infusion bag itself becomes smaller, and the movable column will reset and rise under the action of the elastic member. During the rising process, it will contact the corresponding sensing rod above it and drive the sensing rod up to the natural state. The sensing rod will drive the blocking rod to rise above another water conduit, and then the second infusion bag will start to infuse. This process realizes automatic liquid replacement, and the patient does not need to pay attention to the infusion process at all times, and it also reduces the workload of medical staff.
[0020] If the patient raises his infusion arm due to necessary actions or inadvertently during the infusion process, the detection tube will move up with the infusion tube, and the length of the horizontal pipe between the bottom of the detection tube and the sensing tube will become shorter. According to the principle of communicating vessels, the liquid levels in the detection tube and the sensing tube will become higher, and then the float in the sensing tube will rise, thereby driving the valve stem to rise. During the rising process of the valve stem, the valve port corresponds to the connecting port. Under the action of the air pump, the movable cylinder can be inflated through the air guide tube. The air pressure in the movable cylinder increases, and the piston block will drive the lifting column to rise. The lifting column drives the support frame on one side of the movable rod to rise, thereby raising the infusion bag, ensuring a safer height difference between the infusion end and the infusion bag, preventing blood backflow, and improving the safety of infusion. During the infusion process, when the infusion arm returns to its downward position, the liquid levels in the detection tube and the sensing tube will drop, and the valve rod will move down and reset, the air pressure in the movable tube will be released, the lifting column will move down and reset, and then drive the carrying plate to move down, and the infusion bag will also move down to its original height to prevent the height difference between the infusion bag and the infusion end from being too large, and the flow rate from being too fast to affect the safety of the infusion. When the infusion is completed and there is no liquid in the transition tube, the floating block will drive the monitoring rod to move down. When the monitoring rod is reset, the detection port corresponds to the vent on the ventilation block below. The air flowing under the action of the fan passes through the alarm whistle to sound an alarm, which increases the medical staff's ability to remove the needle in time and ensures safety. Generally speaking, it is easy to operate and use, improves the safety of patient infusion, reduces the workload of medical staff, and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The pneumatic assembly includes a movable cylinder 11, which is fixedly connected to the air guide tube 32 and is internally connected. A support member 40 is fixedly arranged in the movable cylinder 11, and a piston block 38 is fixedly arranged on the top of the support member 40. A lifting column 39 is fixedly connected to the top of the piston block 38.

[0048] A clamping rod 34 is slidably provided on the fixing ring 27 , and a compression piece 35 is sleeved on one end of the clamping rod 34 . One side of the fixing ring 27 is fixedly connected to the infusion tube 6 , and both ends of the compression piece 35 are fixedly connected to the clamping rod 34 and the fixing ring 27 , respectively.
[0049] The lengths of the sensing rods 18 corresponding to the active columns 21 at different positions are different, and as the distance between the active column 21 and the fixed frame 15 becomes smaller, the sensing rod 18 becomes shorter. At the same time, multiple sensing rods 18 are longitudinally equidistantly distributed on the blocking rod 24, and the lengths of the sensing rods 18 become shorter from top to bottom, that is, the active column 21 farthest from the fixed frame 15 corresponds to the uppermost sensing rod 18 on the blocking rod 24.
[0050] During the implementation of the present invention, medical personnel place the medicine bags that need to be infused in the limiting rings 41 respectively. Under the action of the gravity of the infusion bag itself, the movable column 21 will be driven to move downward, and the movable column 21 will drive the connecting rod 19 to move downward. At the same time, the medical personnel will insert the needle tube 50 into the infusion port of the infusion bag. In the initial state, the blocking rod 24 is under the action of the limiting sleeve 29, and its bottom end is above the water guide tube 23 at the bottom of the liquid guide tube 26. Therefore, the infusion is first carried out from the leftmost infusion bag, and the liquid flows into the transition tube 25 through the collecting pipe 31. The floating plate 44 in the transition tube 25 will drive the monitoring rod 51 to rise a distance under the action of the liquid, and then the liquid passes through the folding tube 47 into the heating box 5. When the weather temperature is low, the medical personnel can start the electric The heat rod 46 heats the liquid in the folding tube 47 to make the infusion more comfortable. The liquid finally enters the patient's vein through the infusion tube 6. At this time, the fan 28 and the air pump 10 are started, and the medical staff can leave. The device performs normal infusion. When the infusion of the first infusion bag is completed, due to the weight of the infusion bag itself becoming smaller, the movable column 21 will reset and rise under the action of the elastic member 20. During the rising process, it will contact the corresponding sensing rod 18 above it and drive the sensing rod 18 to the natural state. The sensing rod 18 will drive the blocking rod 24 to rise to the second liquid inlet 37 from the bottom to the top, and then the second infusion bag starts to be infused. This process realizes automatic liquid replacement, and the patient does not need to pay attention to the infusion process at all times, and also reduces the workload of medical staff.
[0051] If the patient raises his infusion arm due to necessary actions or carelessness during the infusion process, the detection tube 33 will move up with the infusion tube 6, and the length of the horizontal pipe between the detection tube 33 and the bottom of the sensing tube 8 will become shorter. According to the principle of communicating vessels, the liquid levels in the detection tube 33 and the sensing tube 8 will become higher, and then the floating block 49 in the sensing tube 8 will rise and drive the valve stem 9 to rise. During the rising process of the valve stem 9, the valve port 48 corresponds to the connecting port 36. Under the action of the air pump 10, the movable cylinder 11 can be inflated through the air guide tube 32. The air pressure in the movable cylinder 11 increases, and the piston block 38 will drive the lifting column 39 to rise, and the lifting column 39 drives the supporting frame 13 on one side of the movable rod 12 to rise, thereby raising the infusion bag, ensuring a safer height difference between the infusion end and the infusion bag, preventing blood from flowing back, and improving the safety of infusion. In addition, during the infusion process, when the infusion arm returns downward, the liquid levels in the detection tube 33 and the sensing tube 8 will drop, then the valve rod 9 moves down and resets, the air pressure in the movable cylinder 11 is released, the lifting column 39 moves down and resets, thereby driving the supporting plate 17 to move down, and the infusion bag also moves down to the original height, preventing the infusion bag from having a large height difference with the infusion end, and preventing the flow rate from being too fast and affecting the infusion. Infusion safety. When the infusion is completed and there is no more liquid in the transition tube 25, the floating block will drive the monitoring rod 51 to move downward. When the monitoring rod 51 is reset, the detection port 45 corresponds to the vent 14 on the ventilation block 16 below. The air flowing under the action of the fan 28 passes through the alarm whistle 42 to sound an alarm, which improves the medical staff to remove the needle in time to ensure safety. When the infusion of one patient is completed and another patient needs to be infused, another processed infusion device is used for infusion, and the connection end of the water guide tube 23 and the liquid guide tube 26 in the replaced infusion device, and the folding tube 47 and the transition tube are connected. The connecting end of 25 is a threaded connection. The medical staff disassembles the connecting end of the water pipe 23 and the liquid guide tube 26, and disassembles the upper end of the water pipe 23 and the needle tube 50. After disassembly, the water pipe 23 can be pulled out from the positioning rod 22, and the folding tube 47 and the connecting end of the transition tube 25 are disassembled. The folding tube 47 and the infusion tube 6 are disassembled and separated, and the folding tube 47 is pulled out from the heating box 5. Then, disinfectant is added from the openings above the transition tube 25 and the liquid guide tube 26 for sterilization and disinfection. After sterilization and drying with a high-temperature lamp, a new water pipe 23, folding tube 47 and infusion tube 6 are replaced as a spare infusion device.
