Description

Technical Field

[0001] This invention belongs to the field of medical infusion equipment technology, and in particular relates to an infusion device for drug administration. Background Technology

[0002] Medical infusion is a treatment method that delivers sterile medications, nutrients, etc., into the bloodstream via intravenous drip. It can be used to replenish fluids, correct electrolyte imbalances, provide nutritional support, and deliver medications to treat diseases. In this process, an infusion stand is required for infusion administration. The infusion stand suspends the infusion bottle or bag at a suitable height, using gravity to create a pressure difference in the medication, allowing the medication to flow steadily into the blood vessels at a certain speed. This method is a commonly used and effective way of administering medication in clinical medicine. For example, patent CN222341699U discloses an infusion stand.

[0003] Currently, patients encounter the following problems when receiving intravenous medications via IV stands:

[0004] First, to maintain pressure balance within the infusion bottle and ensure the smooth delivery of medication to the patient, the infusion set connected to the bottle needs to draw air from the outside to replenish it. However, the air filter on the infusion set is easily clogged by impurities or dust in the outside air, causing pressure imbalance within the bottle and potentially interrupting medication delivery. If this interruption is not detected in time, especially after the medication has been drained from the infusion set, blood backflow can occur. This backflow may lead to thrombosis, vascular blockage, and increased psychological burden on the patient. Furthermore, when changing the infusion bottle, the infusion set connector is exposed to air, and bacteria in the air may contaminate the connector, allowing bacteria to enter the new infusion bottle and contaminate the medication. This not only affects the reliability of the infusion device but also endangers the safety of the patient during infusion therapy.

[0005] Secondly, in the low-temperature environment of winter, directly administering hypothermic medications that are significantly colder than the patient's body temperature can cause vasoconstriction and spasms, accompanied by pain and discomfort. Furthermore, the low temperature of the medication and the inconvenience of hand movement during infusion can impede blood flow in the patient's hand, preventing the timely delivery of the medication to the whole body. This results in an accumulation of medication at the infusion site, with the blood vessels continuously irritated by a large amount of medication, exacerbating the patient's pain. This not only affects the efficiency of intravenous therapy but also the patient's comfort and safety.

[0006] Therefore, we propose an infusion device for drug delivery to solve the above problems. Summary of the Invention

[0020] Compared with existing technologies, the advantages of an infusion device for drug delivery are:

[0021] 1. Through the design of a miniature air pump, filtration mechanism, three-way valve, and protective mechanism, when a patient requires intravenous infusion therapy, the infusion device is first activated, filling the protective mechanism with sterile, clean air that has been filtered by the filtration mechanism and sterilized by the high temperature of the electric heating element. This sterile, clean air blows out the previously untreated outside air inside the protective mechanism, creating a sterile and clean environment within the mechanism. This prevents the air filters of the infusion bottle and infusion set from being interfered with by dust and bacteria from the outside air. It avoids clogging of the air filter in the infusion set by dust and impurities, and prevents external microorganisms from entering the medication solution through the air filter. This mechanism gives the infusion device a highly efficient protective capability, ensuring that the air filter of the infusion set is not clogged, maintaining the air pressure balance inside and outside the infusion bottle, improving the continuity of the medication administration and infusion process, enhancing the reliability of the infusion device, and ensuring the safety of infusion therapy.

[0022] 2. Through the established gas distribution mechanism, cooling metal coil, and exhaust mechanism, while the cooling metal coil cools the sterile clean air, a temperature sensor monitors the temperature of the sterile clean air inside in real time and sends the temperature value to the PLC controller in the form of an electrical signal. Based on the signal feedback from the temperature sensor, the PLC controller adjusts the temperature of the sterile clean air entering the U-shaped heat insulation tube to be within the range of 20-27 degrees Celsius. In the high-temperature environment of summer, the sterile clean air at 20-27 degrees Celsius is lower than the outside temperature, which can prevent the infusion bottle solution from being affected by the continuous high temperature of the outside environment and changing the properties of the medicine. In the low-temperature environment of winter, the sterile clean air at 20-27 degrees Celsius is sprayed into the infusion bottle through the protective mechanism, which can raise the temperature of the medicine in the infusion bottle, reduce the temperature difference between the medicine and the patient's body temperature, and prevent the medicine with excessive temperature difference from entering the human body and causing vasoconstriction and spasm in the patient. This effectively improves the reliability of the infusion device and enhances the safety and comfort of patients receiving infusion therapy.

[0023] 3. With the hand warming mechanism, during the infusion process, the patient can place the hand connected to the infusion set on the rubber shield inside the U-shaped shell. At this time, sterile clean air at 20-27 degrees Celsius guided by the heat-insulating hose is sprayed onto the patient's skin at the infusion site through the hand warming mechanism. This sterile clean air forms an air film protective layer on the patient's skin surface, preventing external air containing dust and bacteria from infecting the infusion site. Moreover, in the low-temperature environment of winter, the sterile clean air at 20-27 degrees Celsius can also keep the patient's skin warm, promote blood circulation in the hand, and avoid the accumulation of medicine at the infusion site due to obstructed blood circulation. This not only prevents the blood vessels at the infusion site from being continuously stimulated by a large amount of medicine, but also allows the medicine to be smoothly delivered to the whole body through blood circulation, improving the therapeutic effect of infusion and enhancing the safety and comfort of the patient during infusion treatment.

This mechanism enables the infusion device to have high-efficiency protection capabilities, can avoid clogging of the air filter of the infusion set, ensure the balance of air pressure inside and outside the infusion bottle, and thus improve the continuity of the drug administration and infusion process. It can not only improve the reliability of the infusion device but also improve the safety of infusion therapy.

[0033] A hollow cover 12 is fixedly connected to the upper surface of the top plate 11. A vertical partition 13 is fixedly connected to the inner wall of the hollow cover 12. A heat insulation plate 14 is fixedly connected to the outer wall of the vertical partition 13 and the inner wall of the hollow cover 12. A miniature air pump 15 is fixedly connected to the upper surface of the top plate 11. An air inlet hose 16 is fixedly connected to the air inlet end of the miniature air pump 15. An air distribution mechanism 6 is fixedly embedded in the outer wall of the vertical partition 13. The air distribution mechanism 6 includes a three-way pipe 61 fixedly embedded in the vertical partition 13. One air outlet end of the three-way pipe 61 is located above the heat insulation plate 14 and is fixedly connected to an electric regulating valve 62. The other air outlet end of the three-way pipe 61 is located below the heat insulation plate 14. A PLC controller 63 is fixedly connected to the outer wall of the vertical partition 13.

[0034] The upper surface of the hollow cover 12 has a through hole, and the filter mechanism 7 is tightly fitted into the wall of the through hole. The filter mechanism 7 includes a filter cylinder 71. The top end of the filter cylinder 71 is threadedly connected to a limiting threaded ring 72. The inner wall of the filter cylinder 71 is fixedly connected to a support mesh plate 73. The top end of the support mesh plate 73 is movably connected to a filter cloth layer 74. The top end of the filter cloth layer 74 is covered with a cotton wadding layer 75. The top end of the cotton wadding layer 75 is covered with an activated carbon layer 76. The top end of the activated carbon layer 76 is covered with a sponge block 77. The air inlet end of the air inlet hose 16 is fixedly connected to the bottom end of the filter cylinder 71. This mechanism can filter out dust and impurities in the air sucked in by the micro air pump 15.

[0035] Two through holes are opened on the upper surface of the heat insulation plate 14, and electric heating tubes 17 are fixedly connected to the walls of the through holes. The outer walls of the two electric heating tubes 17 are fixedly connected to an exhaust mechanism 8. The exhaust mechanism 8 includes a heating metal coil 81 that is fixedly sleeved with the outer walls of the two electric heating tubes 17. The top end of the heating metal coil 81 passes through the upper surface of the heat insulation plate 14 and is fixedly connected to a cooling metal coil 82. The top end of the cooling metal coil 82 is fixedly connected to the inner wall of the hollow cover 12. A temperature sensor 83 is fixedly embedded in the top end of the hollow cover 12. The detection end of the temperature sensor 83 passes through the top wall of the cooling metal coil 82. The outlet end of the cooling metal coil 82 is fixedly connected to a U-shaped heat insulation tube 84. The outlet end of the U-shaped heat insulation tube 84 passes through the outer wall of the hollow cover 12 and the inner wall of the conical transparent cover 51, and is connected to the internal cavity of the air guide ring 52. The wall of the U-shaped heat insulation tube 84 is fixedly connected to a heat insulation hose 85.

[0036] One exhaust end of the exhaust mechanism 8 is fixedly connected to the top of the protective mechanism 5, and the other exhaust end of the exhaust mechanism 8 is connected to the hand warming mechanism 9. The hand warming mechanism 9 includes a connecting pipe head 91 that is movably and sealingly connected to the bottom end of the heat-insulating hose 85. The bottom end of the connecting pipe head 91 is fixedly connected to a U-shaped shell 92. The inner wall of the U-shaped shell 92 is fixedly connected to a rubber cover 93. The outer wall of the rubber cover 93 has multiple second exhaust holes 94. This mechanism can deliver sterile clean air to the patient's hand skin. Especially in the low temperature environment of winter, sterile clean air at 20-27 degrees Celsius can keep the patient's hand warm, promote blood circulation in the hand receiving infusion, and ensure that the medicine can be delivered to the whole body with the smooth circulation of blood, effectively improving the reliability of the infusion device.

[0037] Vertical partition 13 and heat insulation plate 14 divide the internal cavity of hollow cover 12 into air intake zone 18, heating zone 19 and cooling zone 23. Hollow cover 12 has an exhaust hole 20 on the outer wall of cooling zone 23. Self-damping rolling bearing 21 is fixedly sleeved on the outer wall of connecting cylinder 3. Placement frame 22 for storing U-shaped shell 92 is fixedly connected to the outer wall of self-damping rolling bearing 21. Placement frame 22 can store unused hand warming mechanism 9. Placement frame 22 can be easily put into and taken out by rotating self-damping rolling bearing 21. Self-damping rolling bearing 21 has self-locking feature when not subjected to external rotational force.

[0038] The electric regulating valve 62, the miniature air pump 15, and the electric heating tube 17 are all electrically connected to the output terminal of the PLC controller 63 via wires. The temperature sensor 83 is electrically connected to the input terminal of the PLC controller 63 via wires. The above-mentioned electrical connections and power supply equipment are all existing technologies and will not be described in detail here.

[0039] The operating principle of the present invention is described as follows: Before the patient begins intravenous infusion treatment, the PLC controller 63 first controls the start of the micro air pump 15, the electric regulating valve 62 and the electric heating tube 17. After the micro air pump 15 is started, it draws in outside air through the air inlet hose 16 and the filter mechanism 7. When the outside air passes through the filter mechanism 7, it is initially filtered by the sponge block 77, then by the activated carbon layer 76 for adsorption filtration, and finally purified by the cotton layer 75 and the filter cloth layer 74. The purified air is divided into two airflows through the three-way pipe 61. One airflow enters the cooling zone 23 through the electric regulating valve 62, and the other airflow enters the heating zone 19. Then the air inside the heating zone 19 enters the heating metal coil 81 through the bottom air inlet end of the heating metal coil 81.

[0040] During the process of air entering the heating metal coil 81 from the heating zone 19, the electric heating tube 17 is activated to raise the temperature of the heating metal coil 81. The high temperature is used to sterilize the air entering the heating metal coil 81. The sterilized high-temperature air enters the cooling metal coil 82 to cool down. The air in the cooling zone 23 flows on the surface of the cooling metal coil 82. During this process, it will carry away the heat of the air inside the cooling metal coil 82 and finally be discharged through the exhaust port 20. The air inside the cooling metal coil 82 will enter the U-shaped heat insulation tube 84. The sterile and clean air inside the U-shaped heat insulation tube 84 will enter the protective mechanism 5 and the hand warming mechanism 9.

[0041] The sterile clean air entering the protective mechanism 5 is evenly discharged through the air guide ring 52 and the first exhaust hole 53, blowing out the originally untreated external air inside the protective mechanism 5. Finally, the sterile clean air is discharged from the exhaust gap at the bottom of the protective mechanism 5, so that a sterile clean environment is formed inside the protective mechanism 5. At this time, rotate the locking pin 57 to open the protective transparent cover 55, hang the prepared infusion bottle on the hook 54, insert the infusion set into the bottom of the inverted infusion bottle, and connect the needle at the bottom of the infusion set to the blood vessel in the patient's hand. The drug is automatically administered by the pressure difference formed by gravity, and the infusion treatment is started. Then, close the protective transparent cover 55, and limit the protective transparent cover 55 by the cooperation of the locking pin 57 and the L-shaped locking block 58.

[0042] During infusion, the U-shaped heat-insulating tube 84 continuously supplies sterile clean air into the conical transparent cover 51. This sterile clean air forms an obstructive air curtain within the cavity formed by the conical transparent cover 51 and the protective transparent cover 55. This obstructive air curtain effectively prevents external air mixed with dust and bacteria from approaching the air filters of the infusion bottle and infusion set. This not only prevents the air filters in the infusion set from being clogged by dust and impurities, but also prevents external microorganisms from entering the medication through the air filters and causing bacterial infection. In addition, when changing the infusion bottle in the sterile and dust-free protective mechanism 5, medication contamination can be minimized. This mechanism gives the infusion device a high level of protection, ensuring that the air filters of the infusion set are not clogged, maintaining the air pressure balance inside and outside the infusion bottle, improving the continuity of the medication administration and infusion process, enhancing the reliability of the infusion device, and ensuring the safety of infusion therapy.

[0043] While the cooling metal coil 82 cools the sterile clean air, the temperature sensor 83 monitors the temperature of the sterile clean air inside in real time and sends the temperature value to the PLC controller 63 in the form of an electrical signal. If the temperature is higher than the 27-degree Celsius high temperature threshold preset by the PLC controller 63, the PLC controller 63 will control the opening of the electric regulating valve 62 to increase. The higher the temperature of the sterile clean air, the larger the opening of the electric regulating valve 62, which causes more air in the air intake zone 18 to enter the cooling zone 23 through the electric regulating valve 62, thereby cooling the sterile clean air in the cooling metal coil 82 and preventing its temperature from exceeding body temperature and affecting the efficacy of the medicine in the infusion bottle, thus ensuring the safety of drug administration and infusion.

[0044] If the temperature sensor 83 detects that the temperature of the sterile clean air inside the cooling metal coil 82 is lower than the preset low temperature threshold of 20 degrees Celsius set by the PLC controller 63, the PLC controller 63 will control the opening of the electric regulating valve 62 to decrease. The lower the temperature of the sterile clean air, the smaller the opening of the electric regulating valve 62, thereby reducing the amount of air flowing in the cooling zone 23 and slowing down the cooling rate of the sterile clean air inside the cooling metal coil 82. This ensures that the air temperature entering the U-shaped heat insulation pipe 84 is maintained within the range of 20-27 degrees Celsius. In high-temperature environments during summer, the sterile clean air temperature of 20-27 degrees Celsius is lower than the outside temperature. Temperature regulation can prevent the infusion bottle from being affected by continuous high external temperatures and altering the drug's properties. In low-temperature winter environments, sterile clean air at 20-27 degrees Celsius is sprayed into the infusion bottle through the protective mechanism 5, which can raise the temperature of the drug in the bottle, reduce the temperature difference between the drug and the patient's body temperature, and prevent the drug with excessive temperature difference from entering the body and causing vasoconstriction and spasm in the patient. This temperature regulation function enables the infusion device to resist the interference of high summer temperatures on the drug's properties and avoid the discomfort caused by low winter temperatures during infusion, effectively improving the reliability of the infusion device and enhancing the safety and comfort of patients receiving infusion therapy.

[0045] During the infusion process, the patient can place their hand connected to the infusion set on the rubber shield 93 inside the U-shaped housing 92. The U-shaped housing 92 can be placed anywhere the patient's hand is positioned (such as on an infusion chair, hospital bed, or on the patient). At this time, sterile clean air at 20-27 degrees Celsius is guided into the rubber shield 93 through the heat-insulating tubing 85 and finally sprayed onto the patient's skin through multiple secondary exhaust holes 94. This sterile clean air forms an air film protective layer on the patient's skin surface, preventing external air containing dust and bacteria from infecting the infusion. Furthermore, in the low-temperature environment of winter, the sterile clean air at 20-27 degrees Celsius can keep the patient's hand skin warm, promote blood circulation in the hand, and prevent the accumulation of medicine at the infusion site due to obstructed blood circulation. This not only prevents the blood vessels at the infusion site in the hand from being continuously stimulated by a large amount of medicine, but also allows the medicine to be smoothly delivered to the whole body through blood circulation, improving the therapeutic effect of infusion. This design gives the infusion device the functions of safety protection and hand warming during infusion, further improving the reliability of the infusion device and enhancing the safety and comfort of patients receiving infusion therapy.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
