Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to an automatic radionuclide solution dispensing device. Background Technology

[0002] A radionuclide dressing (patch) is a medical dressing used to treat keloids. This dressing adheres tightly to the skin surface of the lesion and uses short-range beta rays emitted by the isotope to provide localized superficial radiotherapy, thereby destroying the diseased tissue. Currently, the radionuclides used clinically are mainly the solid radioactive source strontium-90 and the liquid radioactive source phosphorus-32. Phosphorus-32 is a liquid isotope with a half-life of only 14 days.

[0003] The manual preparation process of phosphorus-32 radionuclide patches involves multiple steps, including imprinting and cutting, area calculation, drug delivery and drying, and sealing. During the drug delivery (addition of the radionuclide solution) stage, because the phosphorus-32 solution is manually added to the cut filter paper, doctors directly come into contact with the isotope, posing a high risk of radiation exposure and harming the health of the operators. Furthermore, the large number of irregular and varying dosage applications are performed manually, resulting in a significant workload in preparing the radionuclide patches. This heavy workload increases the likelihood of operator errors and leads to considerable psychological stress. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an automatic radionuclide solution dispensing device.

[0005] The objective of this utility model can be achieved through the following technical solution: an automatic radionuclide solution dispensing device, comprising:

[0006] The chassis contains a platform and a planar motion mechanism, with the planar area where the planar motion mechanism is located corresponding vertically to the planar area where the platform is located.

[0007] An automatic drug delivery module is connected to the planar motion mechanism, which is configured to move the automatic drug delivery module directly above any position on the platform. The automatic drug delivery module is configured to dispense liquid medicine.

[0008] Preferably, an image acquisition element is also installed inside the chassis. The planar area where the image acquisition element is located is vertically corresponding to the planar area where the planar motion mechanism is located, and the platform is within the shooting range of the image acquisition element.

[0009] Preferably, the system also includes a control module. The planar motion mechanism, the automatic drug delivery module, and the image acquisition element are all electrically connected to the control module. The image acquisition element is configured to acquire image data of the filter paper on the platform and send it to the control module. The control module is configured to control the movement path of the planar motion mechanism and the action of the automatic drug delivery module based on the image data.

[0010] Preferably, the control module is also configured to calculate the amount of radionuclide solution added based on the image data, thereby generating drug cost data.

[0011] Preferably, the automatic drug delivery module includes an automatic pipette and a lifting mechanism, wherein the lifting mechanism is connected to the planar motion mechanism, and the automatic pipette is connected to the lifting mechanism.

[0012] Preferably, the automatic drug delivery module is configured as a drug delivery pump or a push pump.

[0013] Preferably, the platform is configured as a drying platform with a heating function.

[0014] Preferably, the chassis includes a frame, a top plate, a bottom plate, and four side plates. The frame is configured as a rectangular frame structure. The top plate, the bottom plate, and the four side plates are respectively installed on the six sides of the frame and closed to form a closed box structure. One of the side plates has a window. The image acquisition element is installed on the top of the frame, the planar motion mechanism is installed in the middle of the frame, and the platform is installed at the bottom of the frame.

[0015] Preferably, the side panel having the window is fitted with a door panel capable of sealing the window.

[0016] Preferably, it also includes an exhaust gas purification mechanism, which includes an exhaust pipe with its inlet located near the platform.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. An automatic drug delivery device is provided for the preparation of radionuclide applicators. The planar motion mechanism and the automatic drug delivery module work together to drop the radionuclide solution onto the filter paper of the platform, eliminating the need for manual drug delivery and avoiding direct contact between personnel and radioactive isotopes, thus significantly reducing the workload of radionuclide applicator preparation.

[0019] 2. Compared with the traditional manual drug delivery method, this drug delivery device can more accurately control the amount of drug solution and the dripping position through image acquisition elements. The entire dripping process is completed automatically by the system, from positioning to dripping to drying, without manual intervention, which greatly improves work efficiency.

[0020] 3. The image data acquired by the image acquisition element (such as a camera or industrial camera) includes the shape and size of the filter paper. Based on the image data, the control module can accurately calculate the exact size of the filter paper. According to the size and position of the filter paper, combined with the preset treatment plan or experimental design, the control module calculates the amount of radionuclide solution to be added to the filter paper, thereby automatically calculating the corresponding drug cost. This design also enables the device to automatically calculate drug costs. Attached Figure Description

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, an automatic radionuclide solution dispensing device includes: a housing 100, in which a platform 110 and a planar motion mechanism 120 are installed, the planar area where the planar motion mechanism 120 is located is vertically corresponding to the planar area where the platform 110 is located; an automatic drug dispensing module 200, which is connected to the planar motion mechanism 120, the planar motion mechanism 120 being configured to move the automatic drug dispensing module 200 to any position directly above the platform 110, and the automatic drug dispensing module 200 being configured to dispense the drug solution.

[0027] In this device, the casing 100 serves as the outer shell of the entire drug delivery system. Various functional components are installed inside, and the casing is designed as a relatively sealed structure. This ensures that both drug delivery and drying steps are completed within the casing 100, thus isolating the device from the external environment and preventing direct contact with radioactive isotopes. The planar motion mechanism 120 is a device capable of precise movement in a two-dimensional plane (typically along the X and Y axes). A CoreXY motion mechanism can be selected. The main function of the planar motion mechanism 120 is to drive the automatic drug delivery module 200 to achieve precise positioning. The platform 110 is the structure that carries the filter paper and is located below the automatic drug delivery module 200. In actual use, the operator first places the pre-cut filter paper onto the platform 110, then closes the casing. The control module controls the planar motion mechanism 120 to work with the automatic drug delivery module 200 to drip the drug solution onto the filter paper.

[0028] The automatic drug delivery module 200 is used to add radionuclide solutions onto filter paper. The automatic drug delivery module 200 employs components capable of quantitatively adding liquids, such as automatic pipettes, peristaltic pumps, and push pumps. Specifically, the planar motion mechanism 120 can move the automatic drug delivery module 200 to any position directly above the platform 110, enabling the automatic drug delivery module 200 to add the drug solution onto filter paper located at any position on the platform 110. When dealing with large filter paper pieces or multiple filter paper pieces, the planar motion mechanism 120 moves the automatic drug delivery module 200 along a set trajectory, thereby uniformly adding the drug solution onto the filter paper pieces.

[0029] In the preparation of radionuclide patches, the filter paper needs to be dried after the radionuclide solution is added to complete the drug delivery drying step. Therefore, based on the above implementation method, platform 110 is configured as a drying platform with heating function, that is, platform 110 is designed as a heated bed structure. After the automatic drug delivery module 200 completes the addition of the radionuclide solution, the drying platform heats up to dry the filter paper. In this process, both drug delivery and drying are carried out in a closed environment within the enclosure 100, effectively preventing radioactive vapors that may be generated during drying from contacting the external environment and operators, ensuring the safety and automation of the entire process, and protecting personnel health.

[0030] It should be noted that the preparation steps of the phosphorus-32 radionuclide patch are as follows: imprinting and cutting, area calculation, drug delivery and drying, sealing, and cutting. The drug delivery and drying step requires a doctor to manually add the drug solution (phosphorus-32 radionuclide solution) and then dry it. Therefore, this step carries the highest risk of radiation exposure and is also very labor-intensive, requiring a single doctor to operate it. For these reasons, this solution separates the drug delivery step and completes it using an automated drug delivery device. Furthermore, a drying function can be designed inside the casing 100 to achieve automatic drying after drug delivery; the remaining steps can still be completed manually, while the drug delivery step, which has a high risk of radiation exposure, is completed automatically by the equipment. This design not only greatly reduces the risk of radiation exposure but also improves preparation efficiency and reduces the workload. In addition, the remaining steps can be operated manually, making the radionuclide patch preparation process very flexible.

[0031] Compared to fully automated patch preparation equipment, this drug delivery device, while capable of automating the entire preparation process from cutting, transferring, drug delivery and drying, sealing to final slitting, is more expensive. Furthermore, the size of the patches (patch sheets) that can be produced by fully automated equipment is limited by many factors, generally to 10cm. 2 The size limit has already been reached, but the processing size of this drug delivery device is not limited, and it can meet the drug delivery and drying requirements of filter paper sheets of any size, greatly improving the efficiency of patch preparation.

[0032] Furthermore, while fully automated dressing preparation equipment automates the entire process, some medical staff prefer to manually seal the dressings themselves because manual sealing allows for fine-tuning based on the specific situation, offering greater flexibility. For example, when treating multiple keloids with a single dressing, controlling the relative positions of the filter paper pieces within the dressing is difficult. Even if the relative positions of the filter paper pieces are accurate, doctors can easily misplace them during application. Once misplaced, fine-tuning is almost impossible, and since isotope therapy is extremely sensitive to positional precision, any slight deviation can affect the therapeutic effect. Therefore, many hospitals currently prefer manual sealing in such cases. This involves first applying a film to the patient as a base, then attaching multiple dried, drug-treated filter paper pieces to their respective positions. During attachment, the position of individual filter paper pieces can be fine-tuned, and then another film is applied over the top.

[0033] This drug delivery device allows for a safe and efficient drying process on filter paper. The subsequent sealing process can be carried out using specialized equipment or manually, reducing health risks during patch preparation and maintaining flexibility in the process.

[0034] like Figures 1 to 3 As shown, based on the above-described embodiment, an image acquisition element 130 is also installed inside the chassis 100. The planar area where the image acquisition element 130 is located is vertically corresponding to the planar area where the planar motion mechanism 120 is located, and the platform 110 is within the shooting range of the image acquisition element 130.

[0035] The image acquisition element 130 is preferably a camera, industrial camera, or image sensor (CMOS camera or CCD camera). The image acquisition element 130 can capture images of the filter paper on the platform 110, thereby acquiring the shape, size, and relative position of the filter paper on the platform 110. Then, through a corresponding program or algorithm, it calculates the exact size, coordinates, and drug drop volume of the filter paper, enabling the automatic drug delivery module 200 to accurately and uniformly drop the radionuclide solution onto the filter paper. Furthermore, the image acquisition element 130 can also provide corresponding feedback, thereby adjusting the planar motion mechanism 120 and the automatic drug delivery module 200 based on the feedback to ensure the reliability and accuracy of drug drop delivery. For patients, more precise drug delivery can improve treatment effectiveness and avoid potential harm caused by rough treatment. In addition, increased efficiency can objectively reduce patient waiting time. And reduced costs can also lower treatment expenses for patients.

[0036] Compared to traditional manual drug delivery methods, this drug delivery device can more precisely control the dosage and dripping position of the drug solution through the image acquisition element 130. The entire dripping process is completed automatically by the system, from positioning to dripping to drying, without human intervention, significantly improving work efficiency. Manual operation struggles to guarantee the consistency and accuracy of each drip, is easily affected by human factors (such as hand tremors and visual errors), and has low efficiency and poor repeatability. By integrating the image acquisition element 130, the automatic radionuclide solution dripping device not only far surpasses manual methods in the precise control of drug dosage but also offers significant advantages in efficiency, repeatability, safety, and traceability.

[0037] Based on the above embodiments, a control module is also included. The planar motion mechanism 120, the automatic drug delivery module 200, and the image acquisition element 130 are all electrically connected to the control module. The image acquisition element 130 is configured to acquire image data of the filter paper on the platform 110 and send it to the control module. The control module is configured to control the movement path of the planar motion mechanism 120 and the action of the automatic drug delivery module 200 according to the image data.

[0038] The control module is the control system of the entire automatic nuclide solution dropping and administering device, responsible for coordinating and managing the operations of all functional components. After receiving the image data, the control module uses the built-in image processing algorithm to analyze the shape, size, and relative position of the filter paper. By calculation, it determines the exact size and coordinates of the filter paper, and at the same time evaluates the required amount of liquid medicine to be dropped. Then the control module generates the optimal movement path instruction and sends it to the planar motion mechanism 120. The planar motion mechanism 120 drives the automatic dosing module 200 to directly above the filter paper. The control module issues a dosing command to the automatic dosing module 200, and the automatic dosing module 200 drops the set amount of liquid medicine onto the filter paper, thus completing the automatic dosing step.

[0039] It should also be supplemented that through the above design, the information transfer link in the preparation process of the nuclide applicator can be eliminated. When manually performing the dosing step, the previous staff member needs to transfer the calculated drug dropping strategy to the operator, and this information transfer process is prone to errors. When dosing with this device, there is no need for information transfer, and the entire control is achieved by the control module, eliminating the possibility of errors.

[0040] Furthermore, the drying platform is electrically connected to the control module. After performing the above dosing step, the control module controls the drying platform to generate heat, thereby drying the filter paper with the dropped liquid medicine, and finally completing the drying step. This design enables the entire dosing and drying process to be uniformly scheduled and managed by the control module, enabling this device to achieve the steps of automatic dosing and drying.

[0041] Based on the above embodiments, the control module is also set to be able to calculate the dropping amount of the nuclide solution according to the image data, thereby generating the drug cost data.

[0042] The image data collected by the image acquisition component 130 (such as a camera or an industrial camera) includes the shape and size of the filter paper. Based on the image data, the control module can accurately calculate the exact size of the filter paper. According to the size and position of the filter paper, combined with the preset treatment plan or experimental design, the control module calculates the required dropping amount of the nuclide solution for the filter paper, thereby automatically calculating the corresponding drug cost. This design enables this device to also have the function of automatically calculating the drug cost.

[0043] Embodiment 1:

[0044] As Figure 2 、 Figure 3 shown, in Embodiment 1, the automatic dosing module 200 includes an automatic pipette 210 and a lifting mechanism 220. The lifting mechanism 220 is connected to the planar motion mechanism 120, and the automatic pipette 210 is connected to the lifting mechanism 220.

[0045] The automatic drug delivery module 200 is preferably an ADP pipette with a lifting function. The automatic pipette 210 is the key tool for performing actual pipetting operations; it can quantitatively aspirate and dispense radionuclide solutions through an internal pump or piston structure. The lifting mechanism 220 is preferably a vertically arranged linear module or linear slide. The lifting mechanism 220 is responsible for controlling the up-and-down movement of the automatic pipette 210 in the Z-axis direction, ensuring that it can accurately reach the target height for dispensing or aspirating the drug solution. The planar motion mechanism 120, together with the lifting mechanism 220, forms a complete three-dimensional motion system, enabling the automatic pipette 210 to move freely in three dimensions.

[0046] In the drug delivery step, the planar motion mechanism 120 moves the automatic drug delivery module 200 directly above the target filter paper based on the filter paper position information provided by the image acquisition element 130. The lifting mechanism 220 precisely adjusts the height of the automatic pipette 210 according to the height of the filter paper and the dripping requirements to ensure the optimal dripping position. The automatic pipette 210 performs specific aspiration and dripping operations to complete the precise distribution of the radionuclide solution according to preset parameters.

[0047] Based on Embodiment 1, the chassis 100 has a drug addition area 140, which is located below the motion area of ​​the planar motion mechanism 120.

[0048] The drug addition area 140 is actually an area located near the platform 110. It houses a storage container containing a radionuclide solution, which is then drawn up by the automated pipette 210. The main function of the drug addition area 140 is to work in conjunction with the automated drug delivery module 200, thereby providing the module with the drug solution.

[0049] The drug administration steps in Example 1 are as follows: The control module moves the automatic pipette 210 to directly above the drug addition area 140 via the planar motion mechanism 120. The lifting mechanism 220 lowers the automatic pipette 210, accurately inserting the pipette tip into the storage container within the drug addition area 140. Based on the previously calculated drug dosage using image data and the treatment plan, the control module instructs the automatic pipette 210 to draw the corresponding dose of radionuclide solution. After the solution is drawn, the lifting mechanism 220 raises the automatic pipette 210, detaching it from the storage container. Next, the control module moves the automatic pipette 210 to directly above the filter paper via the planar motion mechanism 120. The lifting mechanism 220 again lowers the automatic pipette 210, bringing the pipette tip close to the surface of the filter paper. The automatic pipette 210 then precisely drips the drawn solution onto the filter paper. After dripping, the lifting mechanism 220 raises the automatic pipette 210, ensuring it is away from the filter paper, ready for the next operation or to return to the drug addition area 140.

[0050] Example 2:

[0051] The automatic drug delivery module 200 is configured as a drug delivery pump or a push pump. The difference between Example 2 and Example 1 is that the drug delivery pump or push pump in Example 2 does not need to draw up the drug solution before each administration.

[0052] In Example 2, when a drug delivery pump is used, a peristaltic pump is preferred. During the drug delivery step, one tubing of the pump is inserted into the drug bottle, thereby continuously drawing the radionuclide solution from the bottle. The other tubing of the pump dispenses a measured amount of the drug onto the filter paper. In this process, the pump does not need to replenish the drug solution through vertical movement; instead, it draws the solution from one end and discharges it from the other.

[0053] In Example 2, when a push pump is used, the medication is stored in a syringe connected to the push pump. The push pump pushes the syringe, causing it to dispense the medication. During this process, the push pump does not need to replenish the medication through vertical movement.

[0054] Furthermore, the drug delivery pump or injection pump is connected to the planar motion mechanism 120 via a lifting mechanism, thereby enabling the drug delivery pump or injection pump to move up and down in the Z-axis direction. The purpose of this lifting is only to bring the drip port of the drug delivery pump or injection pump closer to or further away from the filter paper, and the lifting motion is unrelated to the replenishment of the drug solution.

[0055] like Figures 1 to 3 As shown, based on the above embodiment, the chassis 100 includes a frame 150, a top plate 160, a bottom plate 170, and four side plates 180. The frame 150 is configured as a square frame structure. The top plate 160, the bottom plate 170, and the four side plates 180 are respectively installed on the six sides of the frame 150 and closed to form a closed box structure. One side plate 180 has a window 181. The image acquisition element 130 is installed on the top of the frame 150, the planar motion mechanism 120 is installed in the middle of the frame 150, and the platform 110 is installed at the bottom of the frame 150.

[0056] The frame 150 of the enclosure 100 adopts a robust square frame structure design, providing basic support for the entire equipment. The top plate 160, bottom plate 170, and four side plates 180 are joined together to form a completely enclosed box structure, effectively isolating the internal and external environments, preventing the leakage of radioactive materials, and ensuring the safety of operators. The window 181 is actually just an opening structure, through which operators can place the cut filter paper sheets on the platform 110.

[0057] Based on the above embodiment, the side panel 180 with window 181 is equipped with a door panel that can seal the window 181.

[0058] The door panel can be designed as a hinged door structure or a gate structure for lifting and lowering. The function of the door panel is to seal the window 181, so that the device remains isolated from the outside during the drug delivery drying step. When the door panel is opened, the window 181 is exposed, making it easy to put in and take out the filter paper. In actual use, after the filter paper is placed on the platform 110, the door panel is closed to prevent radioactive vapor from leaking out of the chamber during the subsequent drying step.

[0059] When preparing the radionuclide dressing, the doctor first cuts filter paper into pieces that conform to the shape of the lesion. Then, the filter paper pieces are placed on platform 110 through window 181. Image acquisition element 130 acquires graphic data of the filter paper pieces on platform 110 and sends the image data to the control module. Based on the image data, the control module accurately calculates the precise size, coordinates, required radionuclide solution volume, and drug cost for each filter paper piece. The control module then uses planar motion mechanism 120 to move the automatic pipette 210 directly above the drug addition area 140. Lifting mechanism 220 lowers the automatic pipette 210, causing... The pipette tip is accurately inserted into the storage container. Based on the pre-calculated dosage, the control module instructs the automatic pipette 210 to draw the corresponding radionuclide solution. After the solution is drawn, the lifting mechanism 220 raises the automatic pipette 210, detaching it from the storage container. The control module then uses the planar motion mechanism 120 to move the automatic pipette 210 directly above the filter paper. The lifting mechanism 220 then lowers the automatic pipette 210 again, bringing the pipette tip close to the surface of the filter paper. The automatic pipette 210 then precisely drips the drawn solution onto the filter paper. After dripping, the lifting mechanism 220 raises the automatic pipette 210. After the solution dripping is complete, the control module controls the drying platform to heat up. When the drying time reaches the preset value, the control module stops heating, and the drying process ends. The filter paper can then be removed from the platform 110 and subsequently sealed manually or by equipment.

[0060] Based on the above embodiments, an exhaust gas purification mechanism is also included. The exhaust gas purification mechanism includes an extraction pipe, the air inlet of which is close to the platform 110. In this example, the exhaust gas purification mechanism also includes a filter and a negative pressure device. The negative pressure device draws the gas inside the chamber to the filter for purification through the extraction pipe, collecting and treating radioactive vapors or other harmful gases that may be generated during the drying process, ensuring a safe operating environment.

[0061] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
