Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an infusion device for boron neutron capture therapy. Background Technology

[0002] Boron neutron capture therapy (BNCT) is a precise, targeted binary radiotherapy technique. Its core principle is to deliver boron neutrons into the patient's body via intravenous infusion. Boron compounds, which precisely destroy tumor cells with minimal damage to surrounding normal tissues, have become an important direction for the development of malignant tumor treatment.

[0003] In clinical applications of boron non-invasive chemoembolization (BNCT), continuous and stable infusion of boron is a crucial prerequisite for ensuring therapeutic efficacy. The infusion process needs to last from tens of minutes to several hours. However, slight changes in patient positioning, unconscious limb movements, or accidental external impacts during treatment can easily cause stretching of the infusion tubing. Some devices use elastic tubing to cope with this stretching, but the stretching range of elastic tubing is limited. When the stretching force exceeds its elastic limit, the force can still be transmitted to the puncture needle through the elastic tubing. Some devices use fixed stents to limit the tubing, but when the patient moves, the tubing is prone to rigid friction with the stent, which not only easily causes tubing wear but also directly transmits the stretching force to the needle, still posing a risk of needle dislodgement.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0034] BNC is a binary radiotherapy technique that involves first delivering [a specific type of radiation] into the patient's body. Boron compounds are used to selectively kill cancer cells by irradiating the tumor area with a low-energy neutron beam. After atoms capture thermal neutrons, a nuclear reaction occurs, precisely destroying tumor cells with minimal damage to surrounding normal tissue. Therefore, if a sufficient number of... By selectively enriching boron in tumor cells and then irradiating the tumor area with neutrons, tumor cells can be precisely destroyed at the cellular level while minimizing damage to surrounding normal tissues. To achieve the above effect, patients need to receive intravenous infusion of boron-rich drugs before neutron irradiation to ensure that the boron concentration in the tumor reaches an effective level.

[0035] However, the following technical problems exist in practical applications.

[0036] During BNCT treatment, patients need to be fixed on the treatment bed to receive irradiation. After the needle is inserted into the body, the process may last from tens of minutes to several hours. During this period, the patient's limited movement or body position adjustment may pull on the infusion tubing, which is prone to twisting, kinking or falling off, thus interrupting the infusion and affecting the treatment. Not only can the treatment be interrupted, but it may also cause venous damage to the patient, extravasation of boron drugs and skin irritation, seriously threatening the safety of treatment.

[0037] Therefore, in response to the aforementioned technical problems, the research found that, to solve these problems, firstly, a combination fixing assembly using a silicone suction cup and a bearing-connected rod is used to stably fix the device to the ground. The 360° rotational freedom buffers slight pulling forces, preventing the pulling force from being directly transmitted to the needle. Secondly, a linkage pressure relief structure is constructed, consisting of a sealing cylinder, piston plate, elastic element, and one-way valve. When the pulling force is too large, the pipeline pressure rises synchronously, triggering the pressure relief assembly to release the suction force of the silicone suction cup, allowing the device to actively release and completely cutting off the pulling force transmission path, preventing needle detachment from the root. Simultaneously, a roll and partitioned storage structure is used to prevent pipeline entanglement from exacerbating pulling, a shielding component blocks neutron radiation, and an integrated medicine bag frame and switching valve enable convenient management of multiple medicine bags.

[0038] Based on the above-mentioned inventive discovery, the technical solution of this application is proposed.

[0039] The application scenarios of the device provided in this application are described below.

[0040] Figure 1 This is a schematic diagram of a truss device provided in an embodiment of this application. It should be noted that... Figure 1 The examples shown are merely examples of scenarios in which this application can be applied, to help those skilled in the art understand the technical content of this application, but do not mean that this application cannot be used in other devices, systems, environments or scenarios.

[0041] like Figure 1 As shown, this is an application scenario for an infusion device, which includes: a triangular base 100, a control box 700, and a shielding assembly 500.

[0042] The infusion device is installed in a pre-designed area on the ground next to the BNCT treatment bed. It is used to stably and safely deliver boron-rich drugs to the patient. It solves the problem of tubing pulling and needle dislodgement caused by patient movement during treatment. It also has neutron radiation protection and multi-bag boron drug management functions, and is suitable for continuous infusion needs from tens of minutes to several hours.

[0043] Figure 2 and Figure 3 This is a schematic diagram of the triangular base 100 in the infusion device provided in an embodiment of this application. Figure 2 and Figure 3 As shown, the infusion device includes a triangular base 100, which is the core support carrier of the entire infusion device. It is used to install the storage component 200, the fixing component 300 and the pressure relief component 400. Its structure is adapted to the installation requirements of each component to ensure the overall structure is stable.

[0044] Furthermore, the storage component 200 is installed on the inner wall of the triangular base 100 to separate the wound infusion connection tube 202 and prevent the tube from getting tangled. The storage component 200 includes multiple partitions 201, infusion connection tube 202 and a reel 203. The reel 203 is fixedly installed on both sides of the inner wall of the triangular base 100. The reel 203 provides a winding carrier for the infusion connection tube 202. Multiple partitions 201 are fixedly set on the outer surface of the reel 203 and are evenly distributed along the axial direction of the reel 203 to separate the infusion connection tube 202 wound on the reel 203. The infusion connection tube 202 is wound on the outer surface of the reel 203, with one end penetrating the inside of the sealing cylinder 401 and the other end penetrating the right side of the triangular base 100. The infusion connection tube 202 realizes the transfer and delivery of boron drugs.

[0045] Specifically, the outer surface of the roll 203 is provided with an anti-slip texture, which is a grid-like raised structure that can increase the friction between the roll 203 and the infusion connection tube 202. This effectively prevents the infusion connection tube 202 from slipping off the roll 203 due to slight vibration or pulling during the infusion process. Multiple partitions 201 and the roll 203 are integrally molded and are all made of medical-grade ABS. The spacing between adjacent partitions 201 is 2-5cm, which can be flexibly adapted according to the diameter of the infusion connection tube 202 to ensure that the infusion connection tube 202 is not squeezed or tangled after winding, thus ensuring smooth delivery of boron drugs.

[0046] Furthermore, a fixing component 300 is used to fix the triangular base 100. The fixing component 300 is installed at the bottom of the triangular base 100. The fixing component 300 includes a silicone suction cup 301, a suction cup base 302, and a connecting rod 303. One end of the connecting rod 303 is connected to the center of the bottom of the triangular base 100 through a bearing, and the other end of the connecting rod 303 is fixedly connected to the top of the suction cup base 302. The silicone suction cup 301 is installed at the bottom of the suction cup base 302, and a pressure relief hole is provided on one side of the suction cup base 302.

[0047] Specifically, the bearing is a deep groove ball bearing, with its outer ring interference-fitted with the mounting hole at the bottom of the triangular seat 100, and its inner ring interference-fitted with the connecting rod 303, ensuring that the connecting rod 303 can rotate smoothly 360° without jamming, thus buffering the pulling force when the patient moves slightly. The connecting rod 303 is made of medical-grade 304 stainless steel, which has sufficient tensile strength to prevent bending or breakage during pulling. The silicone suction cup 301 has a corrugated adsorption surface, and the vacuum adsorption force can reach 15-20N, which can stably fix the device to the ground, and the adsorption force is not affected by the ground material, such as plastic, metal, wood, tile, etc. The suction cup seat 302 is made of medical-grade ABS material, and its pressure relief hole is fixedly connected to the pressure relief pipe 404 by threads, ensuring a stable and sealed connection.

[0048] Furthermore, Figure 4 This is a schematic diagram of the internal structure of the sealing cylinder in the infusion device provided in an embodiment of this application. Figure 4 As shown, a pressure relief assembly 400 for rapid pressure relief is installed on the left side of the triangular base 100. The pressure relief assembly 400 includes a sealing cylinder 401, a flow guide hose 402, a one-way valve 403, a pressure relief pipe 404, a piston plate 405, and an elastic element 406. The sealing cylinder 401 is fixedly disposed on the left side of the triangular base 100. One end of the infusion connection pipe 202 penetrates the interior of the sealing cylinder 401 and fits against the inner wall of the sealing cylinder 401. The piston plate 405 is movably embedded in the inner wall of the sealing cylinder 401 and fixedly sleeved on the outer surface of the infusion connection pipe 202. The elastic element 406 is disposed between the inner wall of the sealing cylinder 401 and the piston plate 405. The outer surface of the sealing cylinder 401 is provided with a pressure relief port. One end of the flow guide hose 402 is connected to the pressure relief port, and the other end of the flow guide hose 402 is connected to one end of the pressure relief pipe 404. The other end of the pressure relief pipe 404 is fixedly connected to the pressure relief hole of the suction cup seat 302. The one-way valve 403 is installed on the outer surface of the pressure relief pipe 404. The sealing ring is sealed and fitted to the edge of the piston plate 405. The elastic element 406 can be a compression spring or an elastic rubber column, and its preload is 5-10N.

[0049] Specifically, the sealing cylinder 401 is made of medical-grade transparent PC material, which facilitates medical staff to observe the working status of the internal piston plate 405. The sealing ring on its inner wall is made of nitrile rubber, which fits tightly with the edge of the piston plate 405 to effectively prevent gas leakage. The piston plate 405 is also made of nitrile rubber, and its inner ring is fixedly sleeved on the outer surface of the infusion connection tube 202 by a medical-grade clamp to ensure that it moves synchronously with the infusion connection tube 202 when it is subjected to force. The drainage hose 402 is made of medical-grade polyurethane material, which has good flexibility and pressure resistance. The pressure relief pipe 404 is made of medical-grade stainless steel pipe, and its two ends are fixedly connected to the drainage hose 402 and the pressure relief hole of the suction cup seat 302, respectively. The one-way valve 403 is directed from the sealing cylinder 401 to the adsorption chamber of the silicone suction cup 301, ensuring that the pressure can only be released in one direction and preventing external air from entering the sealing cylinder 401 in the opposite direction and disrupting the vacuum environment of the silicone suction cup 301.

[0050] In this embodiment, the storage component 200, the fixing component 300, and the pressure relief component 400 work together to form a three-level protection mechanism of anti-pull, buffering, and pressure relief, which effectively solves the problem of needle detachment.

[0051] The first-level protective storage component 200 prevents entanglement. The infusion connection tube 202 is wound around the reel 203 with a partition 201. The partition 201 prevents the tube from tangling or getting caught on external objects, reducing the risk of pulling from the source. The anti-slip texture of the reel 203 ensures that the tube will not slip when there is slight vibration or pulling, maintaining the stability of the delivery path. At the same time, the infusion connection tube 202 is wound around the reel 203 in a spiral shape similar to a telephone cord spring, which has a certain elastic tensile capacity. When the patient is not moving, the infusion connection tube 202 is naturally coiled. If the patient moves and causes traction, the infusion connection tube 202 can be stretched to provide additional length buffer.

[0052] The secondary protective fixing component 300 provides cushioning force. The fixing component 300 uses a silicone suction cup 301 to stably fix the device to the ground, preventing the tubing from being pulled due to device displacement. When the patient moves slightly or the tubing is pulled slightly, the connecting rod 303 rotates 360° through the bottom bearing, converting the linear pulling force into rotational motion, cushioning the impact force, and preventing the pulling force from being directly transmitted to the connection between the infusion connecting tube 202 and the infusion tube 502, thereby protecting the puncture needle.

[0053] The breaking force of the three-level protective pressure relief component 400 is such that when the pulling force exceeds the buffer limit (e.g., when the patient turns over violently or there is an accidental collision with an external person), after the triangular seat 100 rotates with the connecting rod 303, one of the infusion tubes 502 will continue to pull the infusion connecting tube 202. At this time, the infusion connecting tube 202 drives the piston plate 405 to move synchronously, further stretching the elastic element 406. The elastic element 406 uses its own elasticity to reduce the impact force at the moment of pulling, achieving buffering and force relief. When the pressure in the pipeline exceeds the pre-tightening force of the elastic element 406, the piston plate 405 moves along the inner wall of the sealing cylinder 401 towards the pressure relief port. The infusion connecting tube 202 and the inner wall of the sealing cylinder 401 are connected by an interference fit. A sealing effect is achieved, forming a closed cavity inside the sealing cylinder 401. When the piston plate 405 moves, the volume change of the closed cavity generates high-pressure gas. The high pressure in the pipeline is transmitted through the guide hose 402 and the pressure relief pipe 404 to the pressure relief hole of the suction cup seat 302 via the one-way valve 403, and enters the suction chamber of the silicone suction cup 301, breaking the vacuum environment and causing the silicone suction cup 301 to actively release. The entire device is separated from the ground, completely cutting off the transmission path of the pulling force to the puncture needle, preventing needle dislodgement from the root. When the pulling force is eliminated, the rebound force of the elastic element 406 pushes the piston plate 405 to reset. Medical staff can press the silicone suction cup 301 again to restore the device fixation, without affecting subsequent treatment.

[0054] Furthermore, Figure 5 This is a schematic diagram of the internal structure of the shielding sleeve in the infusion device provided in an embodiment of this application. Figure 5 As shown, the infusion device also includes two shielding components 500 for shielding neutron radiation. Each shielding component 500 includes a shielding sleeve 501 and an infusion tube 502. One end of each infusion tube 502 is connected to both ends of the infusion connection tube 202. The other end of one infusion tube 502 is connected to a human vein through a needle, and the other end of the other infusion tube 502 is connected to one end of the infusion guide tube 705. The two shielding sleeves 501 are respectively fitted onto the outer surface of the corresponding infusion tube 502. The shielding sleeves 501 are made of boron polyethylene or boron-containing rubber. The shielding sleeves 501 are flexible sleeves, and the inner wall of the shielding sleeves 501 is fitted to the outer wall of the corresponding infusion tube 502.

[0055] Specifically, the infusion tubing 502 is made of medical-grade silicone, possessing excellent biocompatibility and flexibility. It connects to the infusion connection tubing 202 via a medical-grade quick-connect fitting for a detachable, sealed connection, facilitating post-treatment disinfection and reuse, and allowing for rapid replacement as needed. The length of the infusion tubing 502 is adapted to the installation spacing of the BNCT treatment bed and device, satisfying the patient's need for slight movement while avoiding the risk of entanglement due to excessive tubing length. The shielding sleeve 501 is made of boron-rich polyethylene or boron-containing rubber, both materials possessing excellent neutron shielding performance. It effectively absorbs scattered neutrons generated after neutron irradiation of the boron-rich drug within the infusion tubing 502, reducing the radiation exposure risk for medical personnel and patients. The shielding sleeve 501 has a flexible structure, allowing free bending with the infusion tubing 502 without affecting clinical puncture procedures or patient positioning. Its inner wall fits tightly against the outer wall of the infusion tubing 502 without significant gaps, preventing neutron scattering from gaps and protecting the infusion tubing 502, reducing wear caused by pulling and friction, and extending the tubing's service life.

[0056] Furthermore, Figure 6 and Figure 7 This is a schematic diagram of the control box 700 in the infusion device provided in an embodiment of this application. Figure 8 for Figure 7 Enlarged view of point A in the middle. (See image below.) Figure 6 , Figure 7 and Figure 8 As shown, a liquid guide tube 705 is installed on one side of the control box 700, and a delivery pump 704 is installed on the inner wall of the control box 700. The output end of the delivery pump 704 is connected to one end of the liquid guide tube 705. A medicine bag frame 701 is fixedly installed on the side of the control box 700 away from the liquid guide tube 705. A Y-shaped tube 702 is installed inside the medicine bag frame 701. A puncture suction head 703 is installed at the input end of the Y-shaped tube 702. A switching valve 706 is installed at the output end of the Y-shaped tube 702. The output end of the switching valve 706 is connected to the other end of the liquid guide tube 705. A partition plate is provided inside the medicine bag frame 701 to separate different medicine bags.

[0057] Specifically, the delivery pump 704 is a miniature precision peristaltic pump, which can set the boron infusion rate according to the patient's weight, tumor type, and treatment plan to ensure that the boron concentration in the tumor area reaches an effective therapeutic level. The delivery pump 704 adopts a peristaltic delivery method to avoid direct contact with the boron drug, prevent drug contamination or changes in composition, and ensure treatment safety. The switching valve 706 is an electric three-way valve or four-way valve, which is electrically connected to the control panel outside the control box 700. Medical staff can quickly switch between different drug bags with one-button operation without manually changing the pipeline joints, avoiding interruption of drug solution, leakage, or air entering the pipeline during the switching process.

[0058] In this embodiment, by installing two shielding components 500 on the infusion tube 502 near the patient's venous puncture end and the control box's infusion tube connection end respectively, neutron radiation protection is formed. This ensures that scattered neutrons are effectively shielded throughout the entire delivery process of boron drugs from the drug bag to the patient's body, minimizing the radiation exposure risk to medical staff and patients. At the same time, the combination of the partition plate and the multi-input Y-shaped tube 702 enables the device to adapt to the needs of single patients for multiple courses of boron drug infusion at different concentrations, thereby improving treatment efficiency.

[0059] The core workflow of the device in this application is as follows: the infusion device is placed in a preset area on the ground next to the BNCT treatment bed, the silicone suction cup 301 is pressed to expel the internal air, and it is fixed by vacuum adsorption force. The boron-rich drug bag is placed between the partition plates of the drug bag frame 701, the puncture suction head 703 is inserted into the corresponding drug bag, the infusion connecting tube 202 is wound around the partition plates 201 of the roll 203, and the infusion tube 502 and the guide tube 705 are connected in sequence.

[0060] Insert the needle at the end of one of the infusion tubes 502 into the patient's vein, set the infusion rate through the control panel of the control box 700, start the delivery pump 704, and deliver the boron drug into the patient's body through the Y-shaped tube 702, switching valve 706, guide tube 705, infusion tube 502, and infusion connection tube 202. During the treatment, when the patient moves slightly, the connecting rod 303 buffers the pulling force through the rotation of the bearing.

[0061] When a large pulling force occurs, the pressure relief component 400 is triggered, and the silicone suction cup 301 actively releases, cutting off the transmission of pulling force and preventing the needle from falling off. When it is necessary to switch the medicine bag, the switching valve 706 can be used to quickly switch between different medicine bags without interrupting treatment.
