Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to an integrated intravenous catheter and a method for using the same. Background Art

[0002] The core advantage of the integrated intravenous catheter lies in its multi-channel design, which allows medical personnel to connect multiple infusion or drug delivery lines at the same time. This feature is particularly important in complex treatment scenarios because it can ensure that multiple liquids or fluids are delivered to the patient at the same time in precise proportions and speeds. This not only simplifies the treatment process and reduces the risk of infection caused by frequent replacement of infusion lines, but also greatly improves the flexibility and accuracy of treatment. During the treatment process, patients may need to receive combined treatment of multiple liquids according to changes in their condition. The multifunctional characteristics of the integrated intravenous catheter make this combined treatment easy and efficient. As a highly specialized medical device, the integrated intravenous catheter plays an indispensable role in the treatment of patients with cardiovascular diseases. Such patients are often highly dependent on and sensitive to vasoactive liquids because vasoactive liquids can directly affect the contraction and relaxation of blood vessels, thereby regulating key physiological parameters such as blood pressure and blood flow. Through the application of integrated intravenous catheters, these complex treatment needs have been achieved more efficiently, safely and accurately. The design essence of the integrated intravenous catheter lies in its multi-channel or multifunctionality, which enables medical staff to connect multiple infusion or drug delivery lines at the same time. For patients with cardiovascular disease, this means that multiple vasoactive drugs, such as pressors, antihypertensive drugs, vasodilators or inotropes, can be infused at the same time to meet their complex and changing condition needs.

[0003] In the actual application of integrated intravenous catheters, although their original design intention is to improve the flexibility and efficiency of treatment, there is indeed a potential risk that the drug solution is not fully premixed during the flow in the catheter, but only merges and enters the patient's venous system together when it approaches the end of the catheter. This situation may lead to uneven distribution of drug concentration in the blood, which in turn has an adverse effect on the efficacy of the drug. The temperature of the drug should not be ignored. Since the drug is usually at a lower temperature during storage and transportation, when it enters the patient's body through an integrated intravenous catheter, if the temperature is not adjusted in advance, a large temperature difference will be formed with the patient's body temperature. This temperature difference will not only cause discomfort to the patient, such as local cold stimulation or chills, but may also affect the solubility and stability of the drug, thereby affecting its efficacy. Moreover, after the injection of the drug in a bottle is completed, a new bottle of drug is replaced. During the dressing process, the drug needs to go through a necessary transmission time to reach the end of the extension tube while flowing through the extension tube. During this period, the newly injected drug is still in a preliminary distribution state in the extension tube and has not yet been fully mixed. This non-uniform distribution state, coupled with the uneven flow rate that may occur during the subsequent drug discharge process or the time lag in the dressing operation, may cause significant fluctuations in the patient's heart rate and blood pressure, specifically manifested as a downward trend, which has a potential impact on the patient's physiological stability. Summary of the invention

[0041] The shaking mechanism 14 includes a micro motor 141, a first gear 142 and a second gear 143. The micro motor 141 is bolted to the top of the connecting plate 1. The first gear 142 and the output shaft of the micro motor 141 are fixed to each other. The top of the connecting plate 1 is also bolted to the first vertical plate 144 and the second vertical plate 146 respectively. The surface of the first vertical plate 144 is rotatably connected to a transmission rod 145. The surface of the second vertical plate 146 is rotatably connected to a rotating rod 147. The surface of the transmission rod 145 is fixed with a second gear 143, and the second gear 143 is meshed with the first gear 142.

The compression spring 1415 is sleeved on the surface of the movable column 1414. The diameter of the circular plate 1416 is larger than the outer diameter of the compression spring 1415. A roller 1410 is also fixed to the bottom of the sleeve 13. The compression spring 1415 gives a downward reaction force to the movable column 1414 and the circular plate 1416, which makes the roller 1410 close to the surface of the elliptical wheel 149, turning on the micro motor 141. The output shaft of the micro motor 141 drives the transmission rod 149 through the first gear 142 and the second gear 143. 45 rotates, and then the transmission rod 145 drives the rotating rod 147 to rotate through the second bevel gear 1411 and the first bevel gear 148, which drives the elliptical wheel 149 to rotate together, and makes the long radius end and the short radius end of the elliptical wheel 149 contact with the roller 1410 in turn. When the long end of the elliptical wheel 149 contacts with the roller 1410, the sleeve 13 moves upward, and drives the movable column 1414 and the circular plate 1416 to move upward, so that the compression spring 1415 is in a compressed state. When the short radius end of the elliptical wheel 149 contacts with the roller 1410, the sleeve 13 moves downward, thereby making the sleeve 13 reciprocate up and down.

[0042] A box body 17 is bolted to the top of the connecting plate 1 and on one side of the micro motor 141. A battery 22 is arranged inside the box body 17. A charging socket 23 is arranged on the surface of the box body 17. The charging socket 23 is used to charge the battery 22. The battery 22 is used to supply power to the micro motor 141. An operation button 24 is also arranged on the top of the box body 17, and the operation button 24 is electrically connected to the micro motor 141. The operation button 24 can control the opening or closing of the micro motor 141.

[0043] The heat generating mechanism 15 includes a fixed plate 151, a friction plate 152 and a heat conducting block 153. The fixed plate 151 is bolted to the top of the connecting plate 1, the friction plate 152 is bolted to the surface of the fixed plate 151, and the heat conducting block 153 is arranged through the surface of the ferrule 13. The surface of the heat conducting block 153 located on the inner side of the ferrule 13 is designed in an arc shape so as to adapt to the surface of the connecting tube 4. During the up and down movement of the ferrule 13, it can drive the heat conducting block 153 to reciprocate along the surface of the friction plate 152. The heat conducting block 153 and the friction plate 152 are both made of metal, while other components such as the first vertical plate 144, the first gear 142, the box body 17, the transmission rod 145, etc. can be made of plastic materials, such as plastic gears and plastic rods, to reduce the overall weight of the surface of the connecting plate 1. The heat conducting block 153 and the friction plate 152 are repeatedly rubbed to generate heat.

[0044] The auxiliary mixing mechanism 16 includes a bearing seat 161 and a rotating rod 162. The bearing seat 161 is fixed inside the connecting tube 4. The rotating rod 162 is rotatably connected to the bearing seat 161. The surface of the rotating rod 162 is also integrated with a blade 163. The surface of the blade 163 is penetrated by a plurality of circular holes 164. When the ferrule 13 shakes up and down, it can drive the connecting tube 4 to shake up and down together, so that the internal blades 163 and the rotating rod 162 tend to rotate, thereby achieving the effect of auxiliary mixing of the liquid medicine.

[0045] When working, first use the first strap 181 and the second strap 183 to surround the patient's arm, and fix the connecting plate 1 on the patient's arm with the Velcro thorn surface 182 and the Velcro fur surface 184. If the fixation is unstable, you can use medical tape to assist in fixing it. Then pick up the connecting tube 4 and press it into the inner side of the ferrule 13 to fix the connecting tube 4 and the ferrule 13. Then connect the third connecting tube 8 to different medicine bottles, and pick up the needle 2 and insert it into the patient's skin for intravenous injection. During the intravenous injection, turn on the micro motor 141, which drives the transmission rod 145 to rotate with the cooperation of the first gear 142 and the second gear 143, and can drive the rotating rod 147 to rotate with the cooperation of the first bevel gear 148 and the second bevel gear 1411, so that the elliptical wheel 149 rotates, and the ferrule 13 is pressed against the roller 1410 under the action of the compression spring 1415. The cooperation between the surface ring 1413 of the elliptical wheel 149 and the movable column 1414 enables the ferrule 13 to have space for up and down movement. The ferrule 13 reciprocates up and down and drives the connecting tube 4 to shake up and down, so that the different medicines entering the connecting tube 4 shake up and down to achieve mixing. In addition, during the shaking process, the rotating rod 162 and the blade 163 can also deflect slightly and slowly to achieve further auxiliary mixing, thereby achieving premixing of different medicines, making the concentration distribution of the medicines in the blood more uniform and ensuring the medicinal properties. In addition, the ferrule 13 drives the heat conducting block 153 to follow the up and down reciprocating movement. The heat conducting block 153 repeatedly rubs against the friction plate 152 to generate heat, which increases the temperature of the heat conducting block 153. In this way, the heat is transferred to the connecting tube 4 to heat the flowing medicine. Although the heating amplitude is not large, the temperature of the medicine is close to the human body temperature to prevent the medicine from being too cold and causing discomfort to the patient.

[0046] During the process of replacing the drug solution, after the subsequent drug solution bottle is connected, the balloon 5 is pressed to deflate the balloon 5, and the internal drug solution flows faster. During the normal flow of the drug solution, the first one-way cover 10 and the second one-way cover 12 can also be pushed open. At this time, the drug solution hits the first one-way cover 10 outward and cannot be opened, but the second one-way cover 12 can be opened. Then the balloon 5 is released, and a space is generated inside. However, the drug solution flowing from the inside of the second connecting tube 6 will subsequently flow faster and fill the balloon 5. The cooperation between the balloon 5, the first one-way cover 10 and the second one-way cover 12 is A principle similar to that of a reciprocating pump is formed, and the medicine liquid entering the connecting tube 4 will not flow back, so that the medicine liquid to be replaced subsequently enters the interior of the connecting tube 4 from the third connecting tube 8, the multi-connector 7, and the second connecting tube 6. In the process of replacing the medicine bottle, the entry of subsequent medicine liquid is accelerated, the delay in changing the medicine is reduced, and the patient's heart rate and blood pressure are prevented from fluctuating significantly during the dressing change process. At the same time, a flow regulator (existing technology, no further description is given here) is also arranged on the surface of the first connecting tube 3 and the third connecting tube 8 to independently adjust the flow rate to prevent discomfort caused by the accelerated flow of the medicine liquid.
