Description

Technical Field

[0001] The present invention relates to a precise speed regulation device for drug infusion in the treatment of lung cancer, which relates to a device for precisely regulating the drug injection speed to avoid adverse reactions. The invention belongs to the technical field of lung cancer treatment, and particularly relates to a precise speed regulation device for drug infusion, which uses an energy supply component to power and control the operation of a detection component and a speed regulation component, monitors the dripping rate in real time through the detection component and alarms when the dripping rate is abnormal, and achieves precise control and mode switching of the dripping rate of the infusion device through air pressure regulation and heating and pressure relief of the speed regulation component, thereby ensuring safe and efficient lung cancer drug infusion. Background Art

[0002] In the treatment of lung cancer, some chemotherapy drugs and targeted therapies require strict infusion rate control. For example, if the drip rate of a slowly infused drug is too fast, it may cause serious side effects such as arrhythmias and liver and kidney damage, or even be life-threatening. However, if the drip rate is too slow, it may lead to insufficient drug concentration and reduced efficacy. Therefore, precise control of drug injection rate is crucial for the safety and effectiveness of treatment. Existing drug injection speed control technology mainly relies on manually adjusting the infusion device's speed regulator to control the flow rate. This method has significant drawbacks. First, the speed regulation is unreliable. If the patient accidentally touches the speed regulator or the speed regulator fails due to mechanical wear or malfunction, it may result in an uncontrolled and rapid infusion of the drug. Especially if the patient or medical staff are unaware of it in time, the rapid entry of high-risk drugs into the body can easily lead to serious medical accidents. Second, medical staff must estimate the flow rate by observing the number of drops in the drip pot and manually calculating the time. This process is subject to human judgment errors (such as line of sight and timing deviation), making it difficult to achieve precise control and easily causing the actual flow rate to deviate from the prescribed flow rate.

[0003] Publication number CN106267460A discloses an infusion speed regulator. The infusion speed regulator includes a shell arranged at the upper end of the infusion tube, characterized in that: a groove is provided inside the shell, the inside of the groove is uniformly serrated up and down, and a slider A and a slider B are fitted together inside the groove. The structure is simple and easy to use; the infusion speed can be accurately adjusted, which brings convenience to the patient's infusion; the cost is low and it is easy to promote and apply. However, in the treatment of serious diseases such as lung cancer, when the slow drip of special drugs needs to be strictly controlled, the above-mentioned infusion speed regulator lacks a mandatory speed limit mechanism. The patient's accidental touch of the speed control button, negligence of medical staff or mechanical failure of the equipment may cause the drip rate to accelerate abnormally. Once the drug infusion speed exceeds the safety threshold, it may not only cause adverse reactions such as palpitations and sudden changes in blood pressure in the patient, but also affect the efficacy of the drug and even endanger life. Summary of the Invention

DETAILED DESCRIPTION Example 1

[0011] The precise speed regulation device for drug infusion in the treatment of lung cancer of the present invention is realized as follows: The precise speed regulation device for drug infusion in the treatment of lung cancer of the present invention comprises an infusion device component, a speed regulation component, a detection component and an energy supply component.

The infusion device assembly consists of a drip pot (2), an infusion tube (1) and a connecting ring (8). The two ends of the drip pot (2) are respectively fixedly connected with an infusion tube (1), and the two infusion tubes (1) are connected through the drip pot (2). A connecting ring (8) is fixedly mounted on the side of the infusion tube (1). The speed regulating assembly is composed of a sealing film (19), a blocking gas chamber (20), a gas transmission branch pipe (12), a gas injection branch pipe (10), a rubber sealing column (9), sealing wax (13), a heat conducting ring (11) and a heating resistance wire (18). The sealing film (19) is placed in the infusion tube (1), the edge of the sealing film (19) is fixedly connected to the inner side of the infusion tube (1), and the sealing film (19) has a cylindrical structure. Preferably, the sealing film (19) is made of elastic silicone material. A blocking gas chamber (20) is formed between the sealing membrane (19) and the infusion tube (1), and the connecting ring (8) is in communication with the inner space of the rubber sealing column (9). One end of the gas transmission branch pipe (12) is connected to the connecting ring (8) by plugging. One end of the gas injection branch pipe (10) is fixedly connected to the side of the gas transmission branch pipe (12) near one end, and the gas injection branch pipe (10) and the gas transmission branch pipe (12) are in communication. A rubber sealing column (9) is fixedly mounted on the other end of the gas injection branch pipe (10). A sealing wax (13) is placed on the inner side surface of the middle portion of the gas branch pipe (12), and the sealing wax (13) is completely in contact with the inner side surface of the gas branch pipe (12). Preferably, the sealing wax (13) is made of a low melting point composite wax material. The heat conducting ring (11) is placed on the gas branch pipe (12). A heating resistance wire (18) is spirally wound between the inner and outer sides of the heat-conducting ring (11). The detection component is composed of a U-shaped buckle (3), an infrared transmitting end (14) and an infrared receiving end (17). The U-shaped buckle (3) is clamped on the drip pot (2) and is arranged close to the top of the drip pot (2). An infrared emitting terminal (14) and an infrared receiving terminal (17) are fixedly mounted on two opposite inner sides of the U-shaped buckle (3) near the middle. The energy supply assembly is composed of a second connecting line (7), a first connecting line (4), a fixed power supply housing (5), an alarm (15), a switch (16), and a hook (6). One end of the second connecting wire (7) is connected to the heating resistance wire (18). One end of the first connecting line (4) is connected to the infrared transmitting end (14) and the infrared receiving end (17) through a power line. The other ends of the first connecting wire (4) and the second connecting wire (7) are connected to a fixed power source in the fixed power supply housing (5). An alarm (15) is provided on the fixed power supply housing (5). A switch (16) is provided on the fixed power supply housing (5). One end of the hook (6) is fixedly connected to the top side of the fixed power supply housing (5), and the hook (6) extends from the end connected to the fixed power supply housing (5) perpendicular to the side connected to the fixed power supply housing (5) to one-third of the way and then bends vertically downward to the other end; When using, when injecting medicine to cancer patients, first inject the medicine that needs to be slowly dripped. Before injecting the medicine, the entire device is hung on the bracket for placing the injection medicine through the hook (6), and the U-shaped buckle (3) is clamped on the drip pot (2). The infrared transmitting end (14) and the infrared receiving end (17) are aligned with the transparent area in the middle of the drip pot to ensure that the infrared rays can penetrate the medicine droplets. The speed of the syringe is adjusted to the maximum to ensure that the medicine dripping speed will not be too fast under any circumstances. Press the switch (16) to fix the power supply in the power shell (5) through the first connecting line ( 4) Power is supplied to the infrared transmitting end (14) and the infrared receiving end (17), which work continuously and calculate the dripping speed of the drug in real time by detecting the light blocking frequency. When the dripping speed is detected to exceed the normal injection speed of the drug, the medical staff passes the syringe needle through the rubber sealing column (9) and injects air into the gas injection branch (10). The air enters the blocking gas chamber (20) through the gas transmission branch (12) and the connecting ring (8) in turn, forcing the elastic silicone sealing membrane (19) to expand toward the central axis of the infusion tube (1), thereby reducing the drug passage space and reducing the flow rate. If the dripping speed is too slow, The air in the blocking gas chamber (20) is extracted through the same rubber sealing column (9), so that the sealing membrane (19) elastically retracts to expand the flow cross-section. This adjustment is repeated until the dripping rate reaches the preset safety range. During the entire injection process, the infrared detection component continuously monitors the drug flow rate. When the speed is abnormal, the alarm (15) immediately emits an audible and visual alarm. When the slow injection stage is completed, the medical staff presses the switch (16) to trigger the power supply in the fixed power supply housing (5), and supplies power to the heating resistor wire (18) in the heat conduction ring (11) through the second connecting line (7) for one minute. The resistor The heat generated by the wire gradually melts the low-melting-point sealing wax (13) in the middle of the gas branch pipe (12). The melted sealing wax flows along the gas branch pipe (12) and solidifies in the area with lower temperature, forming an incompletely sealed channel. At this time, the liquid pressure in the infusion pipe (1) pushes the sealing film (19), so that the air in the blocked gas chamber (20) is discharged through the channel, and the sealing film (19) returns to its initial state. The flow cross-section of the infusion pipe (1) increases, thereby achieving an automatic increase in the injection speed. The patient or accompanying family member can adjust the injection speed of the remaining drugs according to their own physical condition. Example 2

[0012] The difference between this embodiment and embodiment 1 is that: an anti-slip strip (21) is provided on the inner side surface of the U-shaped buckle (3), the anti-slip strip (21) is in a U-shaped structure, and a plurality of the anti-slip strips (21) are arranged equidistantly along the height direction of the U-shaped buckle (3). When in use, the anti-slip strips (21) can increase the friction between the U-shaped buckle (3) and the drip pot (2), thereby preventing the detection component from sliding. A connecting ring (8) is fixedly mounted on the side of the infusion tube (1). The connecting ring (8) is designed to communicate with the inner space of the rubber sealing column (9), thereby separating the gas passage from the liquid medicine passage. This does not affect the liquid medicine transmission, and can achieve flow rate control through air pressure regulation, resulting in a safe and reliable design. The sealing film (19) is placed in the infusion tube (1), and the edge of the sealing film (19) is fixedly connected to the inner side of the infusion tube (1). The sealing film (19) has a cylindrical structure. The sealing film (19) is designed with an elastic silicone material and can expand or retract toward the central axis of the infusion tube (1) under the action of air pressure. The dripping rate is accurately adjusted by changing the flow cross section. The silicone material has good biocompatibility and avoids chemical reaction with the drug solution. The gas injection branch pipe (10) is connected to the gas transmission branch pipe, and the end thereof is connected to a rubber sealing column (9), which provides an independent channel for artificial gas injection / extraction, is easy to operate and has strong sealing performance; The design of the elastic sealing structure of the rubber sealing column (9) supports the automatic rebound of the needle after multiple punctures to prevent gas leakage. Medical staff can quickly intervene in the dripping rate through the syringe, and the emergency response efficiency is high; The heating resistance wire (18) is spirally wound between the inner and outer sides of the heat-conducting ring, and the temperature rises rapidly after power is turned on. By accurately controlling the heating time, the sealing wax (13) is melted in a controlled manner, and the dripping speed mode is switched. The energy supply component can power the detection component and the speed control component and control their operation. The detection component can monitor the dripping rate in real time and alarm when it is abnormal. The air pressure adjustment and heating pressure relief of the speed control component can achieve precise control and mode switching of the infusion device's dripping rate, thereby ensuring the safe and efficient infusion of lung cancer drugs.
