[0015] The present invention arranges a foam column. When the user is infused, the medicine in the medicine bottle can enter the floating section. Under the flow of the medicine, the foam column floats above the medicine, so that the foam column is separated from the squeezing of the first magnet and the second magnet. Under the flow of the medicine, the height of the foam column gradually rises. When the power start switch is turned on, the detection component starts to detect the dripping condition of the medicine of the buffer speed-indicating tube. In winter or when the temperature drops, the first magnet shrinks slightly. After shrinking, the first magnet will not roll over under the impact of the medicine. The foam column gradually rises in height under the flow of the medicine. After the first magnet approaches the guide surface, the guide surface will guide the first magnet into the moving groove. Under the flow of the medicine, the foam column continues to rise in height. The top of the first magnet will abut against the bottom of the start button. Under the flow of the medicine, the foam column continues to rise in height. The first magnet will push the start button to move upward. The start button moves upward, restoring the spring compression, the upper conductive sheet abuts against the lower conductive sheet, the circuit is turned on, the heater is started, and the heater heats the buffer speed-indicating tube to prevent discomfort to the user during infusion in winter or when the temperature drops.
[0016] By setting the first magnet, in summer or when the temperature is moderate, the shape and size of the first magnet expands or remains unchanged, the first magnet cannot move into the moving groove, the first magnet cannot squeeze the start button, and the heating element will not start. When the liquid medicine in the hanging bottle is reduced to a certain weight, the weight alarm will sound an alarm. The weight alarm is electrically connected to the medical system. When the weight alarm sounds an alarm, it will also sound an alarm to the medical system to remind medical staff to replace the hanging bottle or pull out the infusion needle.
[0017] By setting a heating element, when the user is young and the accompanying person is not present, the medicine in the medicine bottle gradually decreases, the medicine in the floating section decreases, the first magnet follows the liquid level of the medicine to drop, the recovery spring recovers, the start button moves downward, the upper conductive sheet is separated from the lower conductive sheet, the circuit is disconnected, the heating element is turned off, and the buffer speed display tube is stopped from being heated, so as to prevent the buffer speed display tube from being damaged due to the lack of medicine in the buffer speed display tube and excessive heating of the buffer speed display tube. At the same time, the temperature of the medicine in the buffer speed display tube is heated, and the temperature of the medicine in the medicine bottle does not need to be heated, which can save energy. At the same time, the length of the medicine in the buffer speed display tube from the human body is shorter than the length of the medicine in the medicine bottle from the human body, which can reduce heat loss and prevent the temperature of the medicine from dropping again during infusion.
[0018] By setting the second magnet, when the medicine in the medicine bottle disappears, the medicine in the floating section disappears, and the bottom of the foam column will abut against the top of the second magnet to prevent the user's blood from flowing back into the bottle due to pressure problems. Under the attraction of the first magnet by the second magnet, and because the foam column becomes soft after being touched by water, the first magnet will squeeze the foam column, so that the medicine inside the foam column will be squeezed out and part of the medicine will flow into the first infusion tube for continued infusion, fully utilizing resources and preventing waste of medicine.
[0019] By setting up a detection part, after the medicine in the medicine bottle disappears, the detection part will send an alarm to the medical care system again when it detects that no medicine has fallen, reminding the medical staff to change the hanging bottle or pull out the infusion needle, and reminding the accompanying personnel to remind the medical staff to change the hanging bottle or pull out the infusion needle, or the accompanying personnel can manually roll the squeezing wheel upward so that the squeezing wheel squeezes the second infusion tube to prevent the user's blood from flowing back into the bottle due to pressure problems and causing accidents. At the same time, two alarm devices are set up, which can send two alarms to prevent one of the alarms from being damaged and unable to remind the medical staff to change the hanging bottle or pull out the infusion needle.
[0020] The present invention has a simple structure and can well protect the safety of the infusion recipient. It can automatically start the heating element in winter or when the temperature drops to heat the medicine to prevent the infusion recipient from feeling uncomfortable during the infusion. At the same time, it is provided with a double alarm function to remind the user or medical staff to replace the hanging bottle or pull out the infusion needle. If the hanging bottle is not replaced or the infusion needle is not pulled out in time, it prevents blood from flowing back into the bottle and can also fully inject the medicine into the infusion recipient.

[0045] During use: 1. Hang the hanging ring of the medicine bottle assembly 30 in the lower hanging buckle 23, insert the infusion needle 67 on the back of the user's hand, and insert the penetration section 51 of the fixing assembly 50 to penetrate the bottle cap 33, so that the medicine in the medicine bottle 32 can enter the floating section 52, and the foam column 82 floats above the medicine under the flow of the medicine, so that the foam column 82 is separated from the squeezing of the first magnet 81 and the second magnet 83. The height of the foam column 82 gradually rises under the flow of the medicine, and the power start switch 74 is turned on, and the detection component 72 begins to detect the dripping condition of the medicine of the buffer speed display tube 62. In winter or when the temperature drops, the first magnet 81 shrinks slightly. After shrinking, the first magnet 81 will not roll over under the impact of the medicine. The foam column 82 gradually rises in height under the flow of the medicine. After the first magnet 81 approaches the guide surface 524, the guide surface 524 will guide the first magnet 81 into the moving groove 522. Under the flow of the medicine, the height of the foam column 82 continues to rise. The top of the first magnet 81 will abut against the bottom of the start button 92.

[0046] 2. In summer or when the temperature is moderate, the shape and size of the first magnet 81 expands or remains unchanged, the first magnet 81 cannot enter the movable groove 522, the first magnet 81 cannot squeeze the start button 92, and the heating element 71 will not start. When the liquid medicine in the hanging bottle is reduced to a certain weight, the weight alarm 22 will sound an alarm. The weight alarm 22 is electrically connected to the medical system. When the weight alarm 22 sounds an alarm, it will also sound an alarm to the medical system to remind medical staff to replace the hanging bottle or pull out the infusion needle 67.
[0047] 3. After the weight alarm 22 sounds an alarm, the medical staff has not replaced the hanging bottle or pulled out the infusion needle 67 in time, and the user is young and the accompanying person is not there. When the medicine in the medicine bottle 32 gradually decreases, the medicine in the floating section 52 decreases, the first magnet 81 follows the liquid level of the medicine to drop, the recovery spring 91 recovers, the start button 92 moves downward, the upper conductive sheet 93 is separated from the lower conductive sheet 94, the circuit is disconnected, the heating element 71 is turned off, and the buffer speed display tube 62 is stopped from being heated to prevent the buffer speed display tube 62 from being damaged due to excessive heating of the buffer speed display tube 62 when there is no medicine in the buffer speed display tube 62. At the same time, the temperature of the medicine in the buffer speed display tube 62 is heated without heating the temperature of the medicine in the medicine bottle 32, which can save energy. At the same time, the length of the medicine in the buffer speed display tube 62 from the human body is shorter than the length of the medicine in the medicine bottle 32 from the human body, which can reduce heat loss and prevent the temperature of the medicine from dropping again during infusion.
[0048] 4. When the medicine in the medicine bottle 32 disappears, the medicine in the floating section 52 disappears, and the bottom of the foam column 82 will abut against the top of the second magnet 83 to prevent the user's blood from flowing back into the bottle due to pressure problems. The first magnet 81 is attracted by the second magnet 83, and because the foam column 82 becomes soft after being touched by water, the first magnet 81 will squeeze the foam column 82, so that the medicine inside the foam column 82 will be squeezed out. Part of the medicine will flow directly into the first infusion tube 61, and the other part will flow into the first infusion tube 61 through multiple leakage ports 830 for continued infusion, giving full play to resources and preventing waste of medicine.
[0049] 5. After the liquid medicine in the medicine bottle 32 disappears, the detection member 72 will send an alarm to the medical care system again when it detects that no liquid medicine has fallen, reminding the medical staff to change the hanging bottle or pull out the infusion needle 67, and reminding the accompanying personnel to remind the medical staff to change the hanging bottle or pull out the infusion needle 67, or the accompanying personnel can manually roll the squeezing wheel 66 upwards so that the squeezing wheel 66 squeezes the second infusion tube 63 to prevent the user's blood from flowing back into the bottle due to pressure problems and causing accidents. At the same time, a double alarm device is set up, which can send two alarms to prevent one of the alarms from being damaged and unable to remind the medical staff to change the hanging bottle or pull out the infusion needle 67.
[0050] 6. In another embodiment, the second magnet 83 is an electromagnet, and the second magnet 83 is electrically connected to the detection member 72. After the foam column 82 floats above the medicine, the power start switch 74 is started. When the medicine in the medicine bottle 32 disappears, the medicine in the floating section 52 disappears, and the bottom of the foam column 82 will abut against the top of the second magnet 83 to prevent the user's blood from flowing back into the bottle due to pressure problems. When the first magnet 81 is attracted by the second magnet 83 and the foam column 82 becomes soft after being touched by water, the first magnet 81 will squeeze the foam column 82, so that the medicine inside the foam column 82 will be squeezed out and part of the medicine will flow into the first infusion tube 61 for continued infusion, making full use of resources and preventing waste of medicine.
[0051] The present invention provides a foam column 82. When the user is given an infusion, the medicine in the medicine bottle 32 can enter the floating section 52. The foam column 82 floats above the medicine under the flow of the medicine, so that the foam column 82 is separated from the squeezing of the first magnet 81 and the second magnet 83. The height of the foam column 82 gradually rises under the flow of the medicine, and the power start switch 74 is started, and the detection component 72 begins to detect the dripping condition of the medicine in the buffer speed display tube 62. In winter or when the temperature drops, the first magnet 81 shrinks slightly. After shrinking, the first magnet 81 will not roll over under the impact of the medicine. The foam column 82 gradually rises in height under the flow of the medicine. After the first magnet 81 approaches the guide surface 524, the guide surface 524 will guide the first magnet 81 into the moving groove 522. Under the flow of the medicine, the height of the foam column 82 continues to rise. The top of the first magnet 81 will abut against the bottom of the start button 92. Under the flow of the medicine, the height of the foam column 82 continues to rise. The first magnet 81 will push the start button 92 to move upward. The start button 92 moves upward, the restoring spring 91 is compressed, the upper conductive sheet 93 and the lower conductive sheet 94 abut together, the circuit is turned on, the heater 71 is started, and the heater 71 heats the buffer speed-indicating tube 62 to prevent discomfort to the user during infusion in winter or when the temperature drops.
[0052] By setting the first magnet 81, in summer or when the temperature is moderate, the shape and size of the first magnet 81 expand or remain unchanged, the first magnet 81 cannot enter the movable groove 522, the first magnet 81 cannot squeeze the start button 92, and the heating element 71 will not start. After the liquid medicine in the hanging bottle is reduced to a certain weight, the weight alarm 22 will sound an alarm. The weight alarm 22 is electrically connected to the medical care system. When the weight alarm 22 sounds an alarm, it will also sound an alarm to the medical care system to remind medical staff to replace the hanging bottle or pull out the infusion needle 67.
[0053] By setting the heating element 71, when the user is young and the accompanying person is not present, the medicine in the medicine bottle 32 gradually decreases, the medicine in the floating section 52 decreases, the first magnet 81 follows the liquid level of the medicine to drop, the recovery spring 91 recovers, the start button 92 moves downward, the upper conductive sheet 93 separates from the lower conductive sheet 94, the circuit is disconnected, the heating element 71 is turned off, and the buffer speed display tube 62 stops being heated, so as to prevent the buffer speed display tube 62 from being damaged due to excessive heating when there is no medicine in the buffer speed display tube 62. At the same time, the temperature of the medicine in the buffer speed display tube 62 is heated, and the temperature of the medicine in the medicine bottle 32 does not need to be heated, which can save energy. At the same time, the length of the medicine in the buffer speed display tube 62 from the human body is shorter than the length of the medicine in the medicine bottle 32 from the human body, which can reduce heat loss and prevent the temperature of the medicine from dropping again during infusion.
[0054] By providing the second magnet 83, when the medicine in the medicine bottle 32 disappears, the medicine in the floating section 52 disappears, and the bottom of the foam column 82 will abut against the top of the second magnet 83 to prevent the user's blood from flowing back into the bottle due to pressure problems. The first magnet 81 is attracted by the second magnet 83, and since the foam column 82 becomes soft after being touched by water, the first magnet 81 will squeeze the foam column 82, so that the medicine inside the foam column 82 will be squeezed out and part of the medicine will flow into the first infusion tube 61 for continued infusion, thereby fully utilizing resources and preventing waste of medicine.
[0055] By setting the detection member 72, after the liquid medicine in the medicine bottle 32 disappears, the detection member 72 will send an alarm to the medical care system again when it detects that no liquid medicine has fallen, reminding the medical staff to change the hanging bottle or pull out the infusion needle 67, and reminding the accompanying personnel to remind the medical staff to change the hanging bottle or pull out the infusion needle 67, or the accompanying personnel can manually roll the squeezing wheel 66 upwards so that the squeezing wheel 66 squeezes the second infusion tube 63 to prevent the user's blood from flowing back into the bottle due to pressure problems and causing accidents. At the same time, two alarm devices are set up, which can send two alarms to prevent one of the alarms from being damaged and unable to remind the medical staff to change the hanging bottle or pull out the infusion needle 67.
[0056] The present invention has a simple structure and can well protect the safety of the infusion recipient. It can automatically start the heating element 71 in winter or when the temperature drops to heat the medicine to prevent the infusion recipient from feeling uncomfortable during the infusion. At the same time, it is provided with a double alarm function to remind the user or medical staff to replace the hanging bottle or pull out the infusion needle 67. If the hanging bottle is not replaced or the infusion needle 67 is not pulled out in time, it prevents blood from flowing back into the bottle and can also fully inject the medicine into the infusion recipient.
[0057] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
