Description

Automatic bubble removal and drug recovery device

This invention is about an infusion tube, in particular, an automatic bubble removal and drug recovery device with two sets of tubes that can be used for automatic bubble removal and residual liquid collection.

In the medical process, an infusion device is a common device used to deliver liquid or nutrient solution to the patient's body. It has a wide range of applications, including drug therapy, intravenous injection, and nutritional supplementation. However, during the infusion process, bubbles may be generated due to air introduced during the liquid mixing process, air residue when the infusion pipeline is connected, or pressure changes during the flow of liquid. If these bubbles are not removed in time, they may pose a threat to the patient's health after being injected into the human body, and may even cause embolism or life-threatening problems.

Due to the above risks, conventional techniques usually use manual methods to remove bubbles, such as removing bubbles from liquid by moving the infusion tube or discharging part of the liquid. However, the manual process of removing bubbles is cumbersome and can easily cause operational burdens for personnel. At the same time, part of the liquid will be discharged when removing bubbles, resulting in liquid waste, especially in the case of expensive or rare drugs, which will cause unnecessary resource loss. In addition, the existing exhaust method cannot completely prevent the liquid from being exposed to the outside air, which may cause the liquid to be contaminated during the exhaust process, further posing a potential threat to the patient.

Furthermore, in some cases, it may be necessary to recycle the remaining liquid. However, the current known technology is prone to cross-contamination of liquids during the process of recycling the remaining liquid, thereby affecting the treatment effect of the patient. Especially when handling highly dangerous liquids, if medical staff accidentally touch these drugs during the recycling process, it may pose a threat to the health of medical staff.

Therefore, it is necessary to provide an infusion device that can automatically remove air bubbles and safely and effectively recover residual liquid.

In view of this, the present invention provides an automatic bubble removal and drug recovery device for transporting a liquid and removing a bubble in the liquid. The automatic bubble removal and drug recovery device comprises a drip chamber, a first pipeline, a second pipeline and a three-way valve. The drip chamber is used to receive liquid from a liquid storage bag. The first pipeline is connected to the drip chamber, and the first pipeline is used to transport liquid. The second pipeline is connected to the drip chamber. The three-way valve has a first interface, a second interface and a third interface. The first interface is connected to the first pipeline, the second interface is connected to a liquid outlet pipeline, and the third interface is connected to the second pipeline. Among them, the drip chamber, the first pipeline, the first interface and the second interface form a first path, and the first path is used for liquid to flow through and transport liquid to the liquid outlet pipeline. The first interface, the third interface, the second pipeline and the drip chamber form a second path, and the second path is used for the liquid and bubbles to flow back to the drip chamber.

The automatic bubble removal and drug recovery device further includes a liquid stopper and a Y-shaped connector. The liquid stopper connects the drip chamber and the Y-shaped connector, a first end and a second end of the Y-shaped connector are connected to the drip chamber and the first pipeline respectively, and has a third end with an air hole on the third end.

When the liquid stopper is opened and the first interface and the second interface are both opened and connected to each other, the first path flow is connected to the liquid outlet pipeline to transport the liquid.

When air bubbles are detected, the stopper is opened and the first and third interfaces are opened and connected to each other, so that the air bubbles flow back to the drip chamber from the second path.

Among them, when the automatic bubble removal and drug recovery device is used to recover the liquid, the liquid stop clamp is closed, the second interface is closed, and the first interface and the third interface are both opened and connected to each other, and the air hole of the Y-shaped joint is opened, so that the liquid remaining in the first pipeline and the second pipeline flows back to the drip chamber.

When the automatic bubble removal and drug recovery device is used to prepare for the transport of recovered liquid, the liquid stop clamp is opened, the first interface and the third interface are both opened and interconnected, and the air hole is closed, so that the recovered liquid is gathered in the first interface.

When the automatic bubble removal and drug recovery device is used to transport the recovered liquid, the third interface is closed and the first interface and the second interface are both opened and connected, so that the recovered liquid is output from the first path to the liquid outlet pipeline.

The drip chamber is further used to receive another liquid to push the recovered liquid, so that the recovered liquid and other liquids fill the first path.

Among them, when the automatic bubble removal and drug recovery device is used to transport the recovered liquid and other liquids, the third interface is closed and the first interface and the second interface are both opened and connected, so that the recovered liquid and other liquids are output from the first path to the liquid outlet pipeline.

Among them, the material of the first pipe and the second pipe is PVC.

In summary, this invention provides an automatic air bubble removal and drug recovery device, including a drip chamber, a first pipeline, a second pipeline, a three-way valve, a liquid stop clamp and a Y-shaped connector. Among them, the drip chamber, the first pipeline, the first interface and the second interface form a first path; the first interface, the third interface, the second pipeline and the drip chamber form a second path. The first path can be used for automatic air bubble removal, liquid collection and residual liquid injection preparation; the second path is used for normal infusion and residual liquid injection. Therefore, the automatic air bubble removal and drug recovery device of this invention can automatically remove bubbles in the liquid during the infusion process. In addition, when it is further necessary to collect residual liquid and inject residual liquid, there is no need to disassemble or replace any components, and all needs can be directly completed through the pipeline inside the automatic air bubble removal and drug recovery device. Compared with the conventional technology, the automatic bubble removal and drug recovery device of this invention not only effectively avoids the cumbersome process of manual exhaust, but also reduces the risk of liquid waste and cross contamination.

Please refer to FIG. 1, which is a schematic diagram of an automatic bubble removal and drug recovery device 1 according to a specific embodiment of the present invention. As shown in FIG. 1, the automatic bubble removal and drug recovery device 1 of the present specific embodiment comprises a drip chamber 10, a first pipeline 11, a second pipeline 12 and a three-way valve 13. The drip chamber 10 is used to receive liquid from a liquid storage bag. The first pipeline 11 and the second pipeline 12 are both connected to the drip chamber 10, and the first pipeline 11 is used to transport liquid. The three-way valve 13 has a first interface 131, a second interface 132 and a third interface 133. The first interface 131 is connected to the first pipeline 11, the second interface 132 is connected to the liquid outlet pipeline 22, and the third interface 133 is connected to the second pipeline 12. The drip chamber 10, the first pipeline 11, the first interface 131 and the second interface 132 form a first path for the liquid to flow through and transport the liquid to the liquid outlet pipeline 22. The first interface 131, the third interface 133, the second pipeline 12 and the drip chamber 10 form a second path for the liquid and bubbles to flow back to the drip chamber.

Please continue to refer to Figure 1. In practice, the automatic bubble removal and drug recovery device 1 of this invention is used to transport liquid and can automatically remove bubbles during the infusion process. As shown in Figure 1, the automatic bubble removal and drug recovery device 1 further includes a liquid stop clamp 14 and a Y-shaped connector 15. The liquid stop clamp 14 is arranged between the drip chamber 10 and the Y-shaped connector 15 and is connected to the drip chamber 10 and the Y-shaped connector 15. The Y-shaped connector 15 has a first end 151, a second end 152 and a third end 153. Among them, the first end 151 is connected to the drip chamber 10, the second end 152 is connected to the first pipeline 11, and the third end 153 has an air hole 154. In practice, the material of the first pipeline 11 and the second pipeline 12 is PVC, but not limited to this.

In actual application, as shown in FIG1 , when the automatic bubble removal and drug recovery device 1 is used for infusion under normal circumstances, the liquid in the liquid storage bag is first introduced into the drip chamber 10, and the liquid stop clamp 14 is arranged between the drip chamber 10 and the Y-shaped connector 15 and is in an open state to allow the liquid to flow. At the same time, the air hole 154 on the third end 153 of the Y-shaped connector 15 needs to remain closed. The drip chamber 10 is connected to the first end 151 of the Y-shaped connector 15 through a pipeline. Then, the liquid flows from the drip chamber 10 through the liquid stop clamp 14, and then flows from the first end 151 of the Y-shaped connector 15 to the second end 152 and enters the first pipeline 11, and then enters the interior of the three-way valve 13 through the first interface 131 of the three-way valve 13. At this time, the first port 131 and the second port 132 in the three-way valve 13 are both opened and connected to each other, and the liquid flows from the first port 131 through the second port 132 to the liquid outlet pipeline 22, and finally delivered to the patient's body. In practice, the pump 16 can be set on the first pipeline 11 to allow the pump 16 to control the delivery pressure and speed of the liquid, but it is not limited to this, and the stop clamp 14 can also be used to manually adjust the flow rate of the liquid.

Next, air may be introduced during the infusion process. When the bubble sensor 17 of the automatic bubble removal and drug recovery device 1 of the present invention detects bubbles inside the device, the automatic bubble removal and drug recovery device 1 will start to remove the bubbles. Please refer to Figure 2, which is a schematic diagram of the automatic bubble removal and drug recovery device 1 according to a specific embodiment of the present invention. As shown in Figure 2, at this time, the liquid stop clamp 14 remains open, and the air hole 154 of the Y-shaped connector 15 is closed. After the second interface 132 of the three-way valve 13 is closed, it is adjusted so that the first interface 131 and the third interface 133 are both open and connected to each other. Then, the pump 16 controls the liquid and the bubbles in the liquid to flow back to the drip chamber 10 along with the liquid from the first pipe 11 through the first interface 131, the third interface 133, the second pipe 12 and the second path of the drip chamber 10 in sequence. After the liquid and the bubbles flow back to the drip chamber 10, the liquid drips in the direction connected to the liquid stop clamp 14 under the action of gravity, and the bubbles are gradually separated and stay at the top of the drip chamber, and finally discharged through the air holes in the drip chamber 10.

When the infusion is completed, the automatic bubble removal and drug recovery device of the present invention will start the recovery of the liquid. Please refer to Figure 3, which is a schematic diagram of the automatic bubble removal and drug recovery device 1 according to one specific embodiment of the present invention. As shown in Figure 3, at this time, the liquid stop clamp 14 is closed, and the air hole 154 of the Y-shaped connector 15 is opened, so that the external air can enter from the air hole 154 to balance the internal pressure. At the same time, the second interface 132 of the three-way valve 13 is closed and adjusted so that the first interface 131 and the third interface 133 are both opened and connected to each other. Then, the liquid remaining in the first pipeline 11 and the second pipeline 12 is driven back to the drip chamber 10 through the pump 16. Since the automatic bubble removal and drug recovery device 1 of the present invention does not need to disassemble or replace any components when recovering liquid, the entire recovery process is carried out in a closed environment. Therefore, it not only effectively reduces the chance of liquid being exposed to the external environment, but also reduces the risk of cross-contamination caused by liquid contact with external air during the recovery process. In addition, the automatic bubble removal and drug recovery device 1 of the present invention can also reduce the need for manual operation, further improving the overall safety and operating efficiency.

After the automatic bubble removal and drug recovery device 1 completes the collection of the residual liquid, it is then ready to transport the recovered liquid. Please refer to Figure 4, which is a schematic diagram of the automatic bubble removal and drug recovery device 1 according to a specific embodiment of the present invention. As shown in Figure 4, at this time, the liquid stop clamp 14 is switched to open, and the air hole 154 of the Y-shaped connector 15 is closed. The first interface 131 and the third interface 133 of the three-way valve 13 are both opened and connected to each other. Then, the recovered liquid flows again from the drip chamber 10 through the liquid stop clamp 14, the Y-shaped connector 15 and flows into the first pipeline 11. At this time, the recovered liquid gathers in the first interface 131.

Next, when the recovered liquid needs to be injected, please refer to FIG. 5, which is a schematic diagram of an automatic bubble removal and drug recovery device 1 according to a specific embodiment of the present invention. As shown in FIG. 5, at this time, the liquid stopper 14 is still open, and the third interface 133 of the three-way valve 13 is closed and adjusted so that the first interface 131 and the second interface 132 are both open and connected to each other. At this time, the recovered liquid flows through the first interface 131 in the first path and then flows from the liquid outlet pipeline 22 to the patient in the delivery position. That is to say, in the stage of recovering liquid and preparing to inject liquid, it is only necessary to switch the connection state of the interface in the three-way valve 13 (that is, just close the third interface 133 and adjust the first interface 131 and the second interface 132 to open), and then the recovered liquid can be injected.

Therefore, the automatic bubble removal and drug recovery device 1 of this invention can not only infuse and automatically remove bubbles, but also collect and inject residual liquid without disassembling or replacing any components. All needs can be met directly through the internal pipeline of the automatic bubble removal and drug recovery device 1.

Furthermore, when it is necessary to transport all the trace amount of remaining recovered liquid and ensure that the liquid is not wasted, the automatic bubble removal and drug recovery device 1 of the present invention can provide a corresponding usage mode. Please refer to Figure 6, which is a schematic diagram of the automatic bubble removal and drug recovery device 1 according to one specific embodiment of the present invention. As shown in Figure 6, at this time, the drip chamber 10 will further receive other auxiliary liquids 30, such as physiological saline or other applicable infusion liquids, and this other auxiliary liquid 30 is fully mixed with the recovered liquid in the drip chamber 10. During this process, the liquid stop clamp 14 remains open, the air hole 154 of the Y-shaped connector 15 remains closed, and the first interface 131 and the third interface 133 of the three-way valve 13 are both opened and connected to each other. Allow other auxiliary liquids and recovered liquids to flow from the drip chamber 10 and the first pipe 11 to the first interface 131. Then, when other auxiliary liquids and recovered liquids gather in the first interface 131. Close the third interface 133 and adjust the first interface 131 and the second interface 132 to be open and interconnected, so that the recovered liquid and other liquids flow from the first interface 131 to the liquid outlet pipe 22.

In summary, the present invention provides an automatic air bubble removal and drug recovery device, comprising a drip chamber, a first pipeline, a second pipeline, a three-way valve, a liquid stop clamp and a Y-shaped connector. Among them, the drip chamber, the first pipeline, the first interface and the second interface form a first path; the first interface, the third interface, the second pipeline and the drip chamber form a second path. The first path can be used for automatic air bubble removal, liquid collection and residual liquid injection preparation; the second path is used for normal infusion and residual liquid injection. Therefore, the automatic air bubble removal and drug recovery device of the present invention can automatically remove bubbles in the liquid during the infusion process. In addition, when it is further necessary to collect residual liquid and inject residual liquid, there is no need to disassemble or replace any components, and all needs can be met directly through the pipeline inside the automatic air bubble removal and drug recovery device. Compared with the conventional technology, the automatic air bubble removal and drug recovery device of this invention not only effectively avoids the cumbersome process of manual air exhaust, but also reduces the risk of liquid waste and cross contamination.
