Description

Technical Field

[0001] This invention relates to the field of medical auxiliary technology, and more specifically to a quantitative drug delivery auxiliary device for use in oncology. Background Technology

[0002] The Department of Medical Oncology is a crucial department in clinical medicine for treating malignant tumors, and chemotherapy is one of its core treatment methods. During chemotherapy, precise and quantitative administration of chemotherapy drugs is paramount. Insufficient dosage may lead to poor treatment efficacy and affect tumor control; while excessive dosage may cause serious toxic side effects, harming the patient's health and even endangering their life. Therefore, achieving precise quantitative drug administration is a key step in ensuring the safety and effectiveness of chemotherapy.

[0003] In the existing technology, devices such as intelligent infusion pumps can deliver a specified dose of medicine to patients. The paper "Analysis of common problems and intervention strategies in the clinical application of infusion pumps" (Zhao Wenjuan, 2021) points out that the use of infusion pumps reduces the workload of medical staff. However, since it is directly related to the health of patients, the safety of infusion pumps should be fully managed to ensure accurate control of the infusion volume.

[0004] Infusion pumps, under the precise control of a computer-controlled intelligent microcomputer system, offer advantages such as accurate infusion volume and uniform drug delivery. However, during actual infusion processes, blood clotting in the tubing or at the needle tip can easily cause blockages, and the needle tip may even dislodge from the puncture site. Therefore, the fundamental flaw of existing technologies lies in the difficulty of achieving dynamic coordination between drug delivery and metering, affecting the continuity and convenience of drug delivery; simultaneously, it is difficult to automatically determine the device's operating status and issue timely alarms when the device malfunctions. Therefore, this invention provides a quantitative drug delivery auxiliary device for oncology departments to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a quantitative drug delivery aid for oncology. Through the design of the delivery box and the metering cylinder, the device can quickly obtain and deliver a specified dose of drug. Furthermore, it can adjust the drug delivery dose at any time during continuous drug delivery without interrupting the drug delivery operation, thereby improving the continuity and convenience of drug delivery. It also monitors the pipeline blockage status in real time and issues an alarm when the pipeline is blocked.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A quantitative drug administration auxiliary device for oncology includes a mounting plate, a liquid storage tank fixedly connected to the side wall of the mounting plate, a delivery box connected below the liquid storage tank, a metering cylinder connected to the side wall of the delivery box, and a drain box connected to the bottom of the delivery box. Both the delivery box and the drain box are fixedly connected to the side wall of the mounting plate. A support platform is fixedly connected to one side of the mounting plate, and the bottom of the metering cylinder is fixedly connected to the top of the support platform. The delivery box is equipped with a flow direction control component for controlling the flow direction of the drug solution, and the metering cylinder is equipped with a quantitative delivery component for delivering a specified dose of drug solution to the drain box. The drain box is equipped with a drain component for discharging the drug solution. The outer wall of the delivery box is equipped with a drive component for driving the flow direction control component and the quantitative delivery component to operate synchronously. The support platform is equipped with a blockage monitoring component for monitoring the overall blockage of the device and triggering an alarm based on the overall blockage of the device.

[0007] The technical principle of the above solution is as follows: The medication is stored in a reservoir. When medication needs to be delivered, a flow control component connects the delivery tank and the metering cylinder, and seals the drain tank, allowing the medication to be delivered from the reservoir to the metering cylinder while preventing premature entry into the drain tank. Simultaneously, the metering delivery component adjusts the capacity of the metering cylinder to hold the specified volume of medication. The flow control component then connects the metering cylinder to the drain tank and seals the reservoir to prevent continuous outflow of medication. At the same time, the metering delivery component delivers the metered medication from the metering cylinder to the drain tank, and the medication in the drain tank is used for subsequent treatment.

[0008] The above approach has the following beneficial effects: 1. The present invention, through the design of the delivery box, can control the flow direction of the liquid medicine; when it is necessary to obtain a quantitative amount of liquid medicine, the storage tank is connected to the metering cylinder to obtain the liquid medicine; when it is necessary to discharge the liquid medicine, the metering cylinder is connected to the discharge tank to discharge the specified dose of medicine; thus, the flow direction of the liquid medicine can be quickly controlled to ensure the feasibility of liquid medicine delivery.

[0009] 2. This invention, through the design of the metering cylinder, can effectively load a specified dose of liquid medicine by adjusting the volume of the metering cylinder, thereby realizing the quantitative acquisition of liquid medicine and providing a basis for subsequent quantitative administration. When the metering cylinder acquires the specified dose of liquid medicine, the device will immediately change the connection relationship between the storage tank and the metering cylinder, as well as the connection relationship between the metering cylinder and the discharge tank, to prevent excess liquid medicine from entering the metering cylinder and affecting the quantitative accuracy. At the same time, it will also promptly transport the quantitative liquid medicine to the discharge tank, improving the continuity of liquid medicine quantitative measurement and delivery.

[0010] 3. Through the design of the metering cylinder and the delivery box, this invention can coordinate the quantitative acquisition and directional delivery of the drug solution. In addition, during the continuous drug delivery process, the delivery dosage of the drug solution can be quickly adjusted by adjusting the volume of the metering cylinder without interrupting the drug delivery operation, thus improving the continuity and convenience of drug delivery.

[0011] 4. In actual infusion, the infusion pump is prone to blockage when blood coagulates in the tubing or at the needle tip. This invention can monitor the overall blockage of the device in real time and issue an alarm in a timely manner based on the overall blockage, so that medical staff can deal with it in time, improve the safety and stability of drug delivery, and ensure the drug delivery effect.

[0012] Furthermore, the conveyor box is cylindrical, and the flow control component includes a rotating column rotatably connected inside the conveyor box. The rotating column has a first through hole and a second through hole, which are interconnected and have a phase difference of 90°.

[0013] Beneficial effects: When the rotating column is rotated to different angles, different connections will be created between the storage tank, the metering cylinder and the discharge tank, thereby quickly changing the flow direction of the medicine.

[0014] Furthermore, the quantitative conveying assembly includes a piston that is laterally slidably fitted inside the quantitative cylinder. A push-pull rod is fixedly connected to the side of the piston away from the conveying box. The end of the push-pull rod away from the piston passes through the side wall of the quantitative cylinder and is laterally slidably fitted therewith. The outer wall of the conveying box is provided with a transmission assembly for driving the push-pull rod to slide laterally along the quantitative cylinder.

[0015] Beneficial effects: When the piston moves in the metering cylinder, it quickly adjusts the effective volume of the metering cylinder, thereby loading different volumes of liquid medicine. At the same time, the movement of the piston also accelerates the acquisition of liquid medicine and realizes the delivery of liquid medicine.

[0016] Furthermore, the drive assembly includes a controller and a dual-head drive unit embedded in the mounting plate. One of the output shafts of the dual-head drive unit passes through the side wall of the conveyor box and is coaxially and fixedly connected to the side wall of the rotating column. The controller is used to control the operation of the dual-head drive unit.

[0017] Beneficial effect: By starting the dual-head drive unit through the controller, the output shaft of the dual-head drive unit will drive the rotating column to rotate, thereby realizing the flow direction control function.

[0018] Furthermore, the blockage monitoring component includes an alarm fixedly connected to one side of the support platform; a sliding groove is opened on the top of the support platform, and a sliding seat is laterally slidably fitted in the sliding groove; the end of the push-pull rod away from the piston is fixedly connected to the side wall of the sliding seat; the transmission component is also used to drive the sliding seat to slide laterally; a speed sensor is embedded in the sliding seat, and the speed sensor is used to collect the sliding speed of the sliding seat; the controller is used to set the speed threshold range, and determine the blockage status of the device based on the speed threshold range and the sliding speed of the sliding seat, and control the alarm to operate according to the blockage status of the device.

[0019] Beneficial effects: When the sliding speed of the slide seat is within the speed threshold range, it means that the current drug delivery operation is normal; when the sliding speed of the slide seat is greater than the speed threshold range, the needle may be dislodged from the blood vessel, and the alarm will sound immediately; when the sliding speed of the slide seat is less than the speed threshold range, the tube or needle may be blocked, and the alarm will sound immediately.

[0020] Furthermore, the transmission assembly includes a connecting rod fixedly connected to the side of the sliding seat near the push-pull rod, a hinge rod hinged to the end of the connecting rod away from the sliding seat, a fixed rod hinged to the end of the hinge rod away from the connecting rod, and a transmission rod fixedly connected to the end of the fixed rod away from the hinge rod. The transmission rod passes through the side of the conveyor box away from the mounting plate and is fixedly connected to the rotating column. The transmission rod is rotatably engaged with the side wall of the conveyor box.

[0021] Beneficial effects: When the rotating column rotates, it also drives the fixed rod to rotate, which in turn drives the hinge rod to swing. The hinge rod then drives the connecting rod to move laterally, which in turn pushes the sliding seat to move laterally in the sliding groove. At the same time, the sliding seat also drives the push-pull rod and the piston to slide laterally in the metering cylinder, realizing the quantitative acquisition and quantitative delivery of drugs.

[0022] Furthermore, a mixing tank is fixedly connected to the side of the mounting plate away from the conveying box, and a stirring shaft is rotatably fitted to the inner side wall of the mixing tank. Several stirring rods are fixedly connected to the stirring shaft. The output shaft of the dual-head drive unit away from the conveying box passes through the side wall of the mixing tank and is fixedly connected to the stirring shaft. The mixing tank is connected to the storage tank, and a first liquid pump is connected at the connection point between the two. The conveying direction of the first liquid pump is from the mixing tank to the storage tank. The controller is used to control the operation of the first liquid pump.

[0023] Beneficial effects: When preparing medicines, the medicine powder and medicine can be put into the mixing tank. When the stirring shaft and stirring rod rotate, the medicine powder and medicine can be mixed evenly to obtain a medicine solution. Then, the first liquid pump can be started by the controller to deliver the medicine solution to the storage tank.

[0024] Furthermore, the drainage assembly includes a second liquid pump fixedly connected to the bottom of the drainage tank, the second liquid pump's delivery direction being from the drainage tank to the outside; the controller is used to control the operation of the second liquid pump.

[0025] Beneficial effects: After a fixed amount of medication is stored in the drainage tank, the second pump can be activated via the controller to drain the medication. It can be taken out directly for oral administration, or the infusion equipment can be connected to the second pump for intravenous infusion to the patient.

[0026] Furthermore, the metering cylinder is made of transparent material, and graduation lines are provided on the outer wall of the metering cylinder.

[0027] Beneficial effects: Users can observe the amount of medicine in the transparent metering cylinder and the corresponding graduation lines, thus quickly knowing the current amount of medicine obtained and delivered.

[0028] Furthermore, the top of the sliding groove is fitted with a shielding frame for horizontal sliding.

[0029] Beneficial effects: The shielding frame can prevent impurities from entering the sliding groove during sliding, thus affecting the quality of the medicine; at the same time, it can also prevent the medicine from spilling and improve the utilization rate of raw materials.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method: Example 1:

[0040] like Figure 1 and Figure 2 As shown, a quantitative drug administration auxiliary device for oncology includes a mounting plate 1. A liquid storage tank 3 is bolted to the side wall of the mounting plate 1. A delivery box 4 is connected to the bottom of the liquid storage tank 3. A metering cylinder 6 is connected to the side wall of the delivery box 4. A drain box 5 is connected to the bottom of the delivery box 4. Both the delivery box 4 and the drain box 5 are bolted to the side wall of the mounting plate 1. A support platform 7 is bolted to one side of the mounting plate 1. The bottom of the metering cylinder 6 is bolted to the top of the support platform 7.

[0041] The delivery box 4 is equipped with a flow control component for controlling the flow direction of the liquid medicine; the metering cylinder 6 is equipped with a metering delivery component for delivering a specified dose of liquid medicine to the discharge tank 5; the discharge tank 5 is equipped with a discharge component for discharging the liquid medicine; and the outer wall of the delivery box 4 is equipped with a drive component for synchronously driving the flow control component and the metering delivery component. The support platform 7 is equipped with a blockage monitoring component for monitoring the overall blockage of the device and issuing an alarm based on the overall blockage status.

[0042] like Figure 4 and Figure 5 As shown, the conveyor box 4 is cylindrical, and the flow control component includes a rotating column 19 rotatably connected inside the conveyor box 4, with a first through hole on the rotating column 19. Figure 5 (middle left) and second through hole ( Figure 5 (Lower middle side), the first through hole and the second through hole are interconnected, and the phase difference between the first through hole and the second through hole is 90°. The drive assembly includes a controller and a dual-head drive component 14 (in this embodiment, the dual-head drive component 14 is a dual-head motor) embedded in the mounting plate 1. One of the output shafts of the dual-head motor passes through the side wall of the conveyor box 4 and is coaxially bolted to the side wall of the rotating column 19. The controller is used to control the operation of the dual-head motor.

[0043] Specifically, such as Figure 5 As shown, in the initial state, the first through hole is connected to the metering cylinder 6, and the second through hole is connected to the drain tank 5. The top of the rotating column 19 seals the bottom of the storage tank 3. After the metered drug administration operation begins, the drug solution is stored in the storage tank 3. The dual-head motor is started by the controller, causing its output shaft to rotate 90° clockwise (in this embodiment, when the rotation angle of the rotating column 19 is between 60° and 90°, the storage tank 3 and the metering cylinder 6 are connected. When the rotating column 19 rotates to 90°, the drug solution flow rate reaches its maximum value). At this time, the first through hole will be connected to the storage tank 3, and the second through hole will be connected to the metering cylinder 6. The drug solution in the storage tank 3 will flow into the metering cylinder 6 until the metering cylinder 6 is full of drug solution, at which point the drug solution can no longer flow. At this time, the dual-head motor is started again by the controller, causing its output shaft to rotate 90° counterclockwise. The rotating column 19 will also rotate accordingly, returning to the initial state. At this time, the drug solution in the metering cylinder 6 will be transported to the drain tank 5, thereby realizing the metered acquisition and metered discharge of the drug solution.

[0044] like Figure 1 and Figure 4As shown, the quantitative conveying assembly includes a piston 18 that slides laterally within the quantitative cylinder 6. A push-pull rod 17 is bolted to the side of the piston 18 away from the conveying box 4. The end of the push-pull rod 17 away from the piston 18 passes through the side wall of the quantitative cylinder 6 and slides laterally with it. The outer wall of the conveying box 4 is provided with a transmission assembly for driving the push-pull rod 17 to slide laterally along the quantitative cylinder 6. A sliding groove is opened on the top of the support platform 7. A sliding seat 13 slides laterally within the sliding groove. The end of the push-pull rod 17 away from the piston 18 is bolted to the side wall of the sliding seat 13. The transmission assembly includes a connecting rod 12 bolted to the side of the sliding seat 13 near the push-pull rod 17. A hinge rod 11 is hinged to the end of the connecting rod 12 away from the sliding seat 13. A fixing rod 10 is hinged to the end of the hinge rod 11 away from the connecting rod 12. The end of the fixing rod 10 away from the hinge rod 11 is bolted to a transmission rod 9. The transmission rod 9 passes through the side of the conveying box 4 away from the mounting plate 1 and is bolted to a rotating column 19. The transmission rod 9 rotates with the side wall of the conveying box 4.

[0045] Specifically, such as Figure 4 As shown, in the initial state, the fixed rod 10 is vertically downward. When the dual-head motor drives the rotating column 19 to rotate clockwise, the rotating column 19 will drive the transmission rod 9 and the fixed rod 10 to rotate clockwise, which in turn will drive the hinge rod 11 to move to the left. The hinge rod 11 will then push the connecting rod 12 and the sliding seat 13 to move to the left. The sliding seat 13 will then drive the push-pull rod 17 and the piston 18 to move to the left inside the metering cylinder 6. At this time, the storage tank 3 is connected to the metering cylinder 6, and the piston 18 will draw the liquid in the storage tank 3 into the metering cylinder 6, accelerating the flow of the liquid and improving the efficiency of the quantitative acquisition of the liquid. Conversely, when the dual-head motor drives the rotating column 19 to rotate counterclockwise, the rotating column 19 will drive the transmission rod 9 and the fixed rod 10 to rotate counterclockwise. The hinge rod 11 will move to the right and pull the connecting rod 12 and the sliding seat 13 to move to the right. The sliding seat 13 will then drive the push-pull rod 17 and the piston 18 to move to the right inside the metering cylinder 6. At this time, the metering cylinder 6 will be connected to the drain tank 5. The piston 18 will transport the liquid in the metering cylinder 6 to the drain tank 5, increasing the delivery speed of the liquid and significantly reducing the residue of the liquid, thereby improving the metering accuracy of the liquid.

[0046] like Figure 4 As shown, during this process, the moving distance of piston 18 can be adjusted by adjusting the rotation angle of the output shaft of the dual-head motor. The larger the reciprocating rotation angle of the output shaft of the dual-head motor, the greater the reciprocating stroke of piston 18, and the more liquid medicine is acquired and delivered; the smaller the reciprocating stroke of piston 18, the less liquid medicine is acquired and delivered. Furthermore, during the adjustment process, it is only necessary to reasonably control the rotation angle of the rotating column 19 (e.g., Figure 5As shown in this embodiment, when the rotating column 19 rotates 60° clockwise, the first through hole will be connected to the liquid storage tank 3, and the second through hole will be connected to the metering cylinder 6. This can effectively adjust the connection between the liquid storage tank 3, the metering cylinder 6, and the drain tank 5, thereby ensuring the continuous delivery of the medicine.

[0047] The blockage monitoring component includes an alarm (not shown in the figure) bolted to one side of the support platform 7; a speed sensor is embedded in the sliding seat 13 to collect the sliding speed of the sliding seat 13; the controller is used to set the speed threshold range and determine the blockage status of the device based on the speed threshold range and the sliding speed of the sliding seat 13, and controls the alarm to operate according to the blockage status of the device, and the alarm will sound an alarm: "There may be a blockage at present, please deal with it in time".

[0048] Specifically, when the sliding seat 13 slides back and forth in the sliding groove, the speed sensor will collect the sliding speed of the sliding seat 13. When the sliding speed of the sliding seat 13 meets the speed threshold range, it means that the current drug delivery operation is normal. When the needle is removed from the blood vessel, the infusion resistance almost disappears, and the output power of the dual-head motor is constant. At this time, the piston 18 and the push-pull rod 17 can slide more smoothly in the metering cylinder 6, and the sliding speed of the sliding seat 13 will also increase accordingly, thus exceeding the speed threshold range. The alarm will immediately sound an alarm: "There may be a needle detachment phenomenon. Please deal with it in time."

[0049] When the infusion tubing or needle (in this embodiment, the infusion tubing and needle refer to the infusion tubing and needle in the prior art) becomes blocked, the infusion resistance will increase sharply, and the sliding speed of the sliding seat 13 will fall below the speed threshold range. The alarm will then immediately sound, reminding medical staff to handle the situation promptly and ensuring the safety and stability of the infusion process. Figure 1 and Figure 3 As shown, a mixing tank 2 is bolted to the side of the mounting plate 1 away from the conveying box 4. A stirring shaft 15 is rotatably fitted to the inner wall of the mixing tank 2, and several stirring rods 16 are bolted to the stirring shaft 15. The output shaft of the dual-head motor away from the conveying box 4 passes through the side wall of the mixing tank 2 and is bolted to the stirring shaft 15. The mixing tank 2 is connected to the storage tank 3, and a first liquid pump is connected at the connection point between the two. The first liquid pump delivers liquid from the mixing tank 2 to the storage tank 3. The controller is used to control the operation of the first liquid pump.

[0050] Specifically, when the dual-head motor is started, the medicine (solvent for the drug powder) and the drug powder can be put into the mixing tank 2. One of the output shafts of the dual-head motor will drive the stirring shaft 15 and the stirring rod 16 to rotate, thereby fully mixing the medicine and the drug powder to obtain a medicine solution. At this time, the first liquid pump (not shown in the figure) is started by the controller, and the first liquid pump will deliver the medicine solution to the storage tank 3 to replenish the medicine solution.

[0051] The drainage assembly includes a second liquid pump (not shown in the figure) fixedly connected to the bottom of the drainage tank 5. The second liquid pump delivers liquid from the drainage tank 5 to the outside. The controller is used to control the operation of the second liquid pump.

[0052] Specifically, after the medication is quantitatively delivered into the drainage tank 5, the second liquid pump can be activated by the controller to directly discharge the medication for oral treatment; alternatively, the infusion device (such as the infusion tubing in the prior art) can be connected to the second liquid pump to achieve quantitative infusion.

[0053] This embodiment, through the design of the delivery box 4 and the metering cylinder 6, enables the device to quickly acquire and deliver a specified dose of drug. At the same time, it can adjust the acquisition and delivery dose of drug at any time during the continuous acquisition and delivery of drug without terminating the drug delivery operation, thus improving the continuity and convenience of drug administration.

[0054] Example 2:

[0055] The difference from Example 1 is that, as Figure 1 As shown, the metering cylinder 6 is made of transparent silicone material, and graduation lines are provided on the outer wall of the metering cylinder 6.

[0056] Specifically, users can observe the amount of medicine in the transparent metering cylinder 6 and the corresponding graduation lines through the cylinder, thus quickly knowing the current amount of medicine obtained and delivered.

[0057] Example 3:

[0058] The difference from Example 2 is that, as Figure 1 As shown, the top of the sliding groove is fitted with a shielding frame 8 for horizontal sliding.

[0059] Specifically, the shielding frame 8 can prevent impurities from entering the sliding groove and affecting the quality of the drug when sliding; at the same time, it can also prevent the drug from spilling and improve the utilization rate of raw materials.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
