Description

Technical Field

[0001] This invention belongs to the field of medical device and medical equipment technology, specifically relating to a modular infusion platform for cavity drug delivery and its assembly and control method. Background Technology

[0002] Existing methods of cavity drug delivery include pressure bottles (enemas, vaginal douches), syringe injection, and simple balloon compression, as well as some infusion systems that combine pumps, drug containers, and tubing. However, most of these existing systems are general-purpose designs and are not specifically designed for the anatomical adaptation, replaceable release components, target area delivery, and control requirements for matching different drug solutions / drug delivery curves in cavity local drug delivery scenarios.

[0003] The problems include: uncontrollable or insufficient control precision of drug delivery rate, drug backflow, cavity irritation, difficulty in compatibility with different cavities and different release components, difficulty in achieving multi-drug synergy, and the separate platform design of low-cost disposable consumables and reusable pump bodies, which has a fixed structure and is difficult to expand. Therefore, there is an urgent need for a modular cavity drug delivery platform based on a reusable micropump drive unit, capable of working in conjunction with different drug storage modules and different cavity-adapted release components. Unlike cavity drug delivery devices that simply combine the drug storage site, delivery device, and release site in a fixed combination, this invention aims to enable the same micropump drive unit to be selectively assembled with different types of drug storage modules and different types of cavity-adapted release components through a modular interface, and to be able to invoke the corresponding infusion parameter set or preset dosing curve based on the selected module combination.

[0053] A method for assembling and controlling a modular infusion platform for cavity drug delivery, comprising: A modular infusion platform is provided, the platform including a micropump drive unit, at least one replaceable drug storage module, and at least one cavity adapter release component; Select the appropriate cavity adapter release component according to the target cavity type and / or target drug delivery requirements, and assemble the micro pump drive unit, the drug storage module and the cavity adapter release component through a modular interface structure to establish a sealed detachable connection and form a drug delivery flow path; Infusion parameters are sent to the micro-pump drive unit through an external control device, and / or the corresponding infusion parameter set or preset dosing curve is loaded based on the selected drug storage module and / or the selected cavity adapter release component.

[0054] This invention provides a modular cavity drug delivery platform. Through the combination of a reusable micro-pump drive unit, a replaceable drug storage module, a cavity-adaptive release component, and a modular interface structure, it achieves the following: compatibility with different cavity shapes; compatibility with various drug containers or drug tanks; scalability to multi-drug, multi-pathway, and multi-consumable structures; execution of infusion parameter sets or preset dosing curves corresponding to the selected drug storage module and / or the selected cavity-adaptive release component via an external control device; and support for the separate design of low-cost disposable consumables and reusable pump bodies.

[0055] This platform provides a unified basic architecture for various cavity drug delivery devices and provides platform support for extended functions related to infusion parameter setting, preset dosing curve control and sensor access.

[0056] In some embodiments, the cavity-adaptive release component of the present invention may further include a diffusion structure for promoting uniform distribution of the drug solution within the cavity. This diffusion structure can take various forms, such as porous layers, adsorption layers, microstructure arrays, hydrophilic coating layers, capillary structures, or other devices capable of improving the uniformity of drug solution distribution, enabling more uniform diffusion of the drug solution within the cavity. It should be noted that this diffusion structure is only an optional additional function and does not constitute a necessary component of the platform structure of the present invention.

[0057] Example 1: Push rod pump + soft bag drug reservoir + rectal adapter release component; This embodiment provides a basic configuration suitable for rectal administration (such as retention enemas, suppository liquefaction infusion, etc.).

[0058] Miniature pump drive unit: A precision push rod pump driven by a motor. This unit includes a stepper motor, a lead screw transmission mechanism, and a push rod. Its internal control circuitry allows it to receive commands via built-in buttons or an external communication interface (such as Bluetooth) to precisely control the push rod's travel speed and stroke, thereby achieving precise control over the drug infusion rate and total volume.

[0059] Medication storage module: A disposable, flexible, sterile medication bag (soft bag shape). The bag outlet has a pre-fabricated Luer connector male. The bag is pre-filled with medication and sealed in an aluminum foil bag; it is unsealed and installed before use. The bag is placed in a rigid bracket connected to the drive unit. The push rod of the pusher pump acts on the piston plate of the bag or directly squeezes the bag body to push out the medication.

[0060] Cavity adapter release component: A disposable rectal catheter. Its insertion end is made of round-tipped silicone with a flexible section to reduce discomfort during insertion. The catheter body is a medical-grade soft tube, with a Luer connector female at its proximal end (external end) for quick connection to the medication bag outlet. The catheter body is marked with depth graduations. An anti-backflow check valve is integrated near the insertion end within the medication delivery path to prevent intestinal fluid or medication from flowing back and contaminating the tubing.

[0061] Modular Interface and Workflow: Insert the rectal catheter into the patient's rectum to the appropriate depth. Remove the pre-filled medication bag from the packaging and insert it into the drive unit's bracket. Rotate the Luer connector of the medication bag to the Luer connector of the catheter. Set the infusion parameters (e.g., slow infusion mode) on the drive unit. After startup, the pusher pump advances at a constant speed, gently infusing the medication through the catheter into the deep rectum. After completion, disconnect the interface, discard the used medication bag and catheter, and disinfect the drive unit or replace the protective cover for future use.

[0062] Example 2: Motor-driven squeeze pump + bottle-shaped medicine container + vaginal tampon-shaped adapter release component; This embodiment provides a formulation suitable for vaginal administration (such as antibacterial gel, estrogen cream, etc.), emphasizing the uniform distribution of the drug solution within the cavity.

[0063] Miniature pump drive unit: Employs a miniature motor-driven squeeze pump. It features a motor-driven, periodically pressable pressure head. This compact unit can be designed as a handheld device, incorporating a built-in rechargeable battery and a simple control chip, providing continuous or pulsed infusion modes.

[0064] Medication storage module: This is a small cylindrical vial (bottle-shaped) with a specially designed screw-lock connector at the opening. The vial is made of a translucent material for easy observation of the remaining amount. It may contain a gel-like medication.

[0065] Cavity-adaptive release device: This is an expandable tampon / umbrella-shaped applicator. Its outer surface is a flexible applicator that can be inserted into the vagina, while its interior contains a highly absorbent, biocompatible diffusion structure. The end of the applicator connects to the medication storage module via a thin tube. Once in place, mechanical or fluid action causes the internal diffusion structure to expand appropriately within the vagina, increasing the contact area.

[0066] Modular Interface and Workflow: Insert the applicator into the predetermined position in the vagina and unfold its diffusion structure. Screw the pre-filled vial into the corresponding interface on the drive unit and lock it in place. Start the device; the pump will pump the gel from the vial through a thin tube into the diffusion structure inside the applicator. Under the pumping pressure and the capillary / porous action of the diffusion structure, the medication is evenly released and distributed onto the vaginal mucosa. After infusion, remove the drive unit and vial. The applicator can be left in place for a period of time before being removed and discarded, or it can be designed as a biodegradable consumable.

[0067] Example 3: Miniature peristaltic pump + corrugated bottle assembly + replaceable adapters; This embodiment demonstrates the platform's precise infusion and multi-drug synergistic capabilities, making it suitable for scenarios requiring continuous or complex dosing regimens (such as colonic infusion and multi-drug irrigation).

[0068] Miniature pump drive unit: Utilizing a multi-channel miniature peristaltic pump as the core drive, the pump head features multiple independent pump tube slots. A precision motor drives multiple rollers to sequentially compress the pump tube, achieving contamination-free transport. The drive unit is equipped with a color touchscreen, a multi-functional sensor interface (compatible with flow and pressure sensors), and advanced control algorithms, supporting closed-loop control based on flow feedback.

[0069] Medication storage module: Consists of multiple compressible corrugated bottles (corrugated bottle shape). Each corrugated bottle is connected to a dedicated peristaltic pump tube. The corrugated bottle design allows the bottle to expand and contract freely during pump suction and discharge, ensuring stable medication delivery and easy monitoring of remaining levels. RFID tags can be attached to the bottles for recording medication information.

[0070] Cavity adapter release components and replaceable interface connectors: Standard tubular cavity adapter release components (such as colonoscopy assist catheters) are used. To accommodate different patient cavity diameters, replaceable interface connectors are provided at the end of the drug delivery path, such as a series of conical transition tips or rectal catheter tips with side holes of different outer diameters and hardness, which can be quickly replaced via magnetic interfaces.

[0071] Modular Interface and Workflow: Multiple corrugated bottles (e.g., drug A, drug B, and flushing solution) are installed into the drive unit bracket, and their pump tubing is inserted into the corresponding channel of the peristaltic pump. Select and connect the appropriate cavity adapter and connector to match the target cavity (e.g., colon). Program the infusion sequence on the control panel (e.g., first infuse 100ml of drug A at a low speed, pause for 5 minutes, then infuse 50ml each of drug B and flushing solution at a medium speed in parallel). The system operates according to the program and can monitor flow rate and tubing pressure in real time, triggering an alarm and shutdown in case of abnormalities. This achieves multi-drug, programmable, and precise cavity infusion.

[0072] Example 4: A universal cavity adapter release component system based on a deformable flexible front end; This embodiment focuses on illustrating the modular adaptation characteristics of the cavity adaptation and release component itself, so as to adapt to multiple cavities with a single component platform.

[0073] Core structure: A universal cavity adapter release component with a flexible tube as its main body is designed. Its most distinctive feature is that the insertion end is not fixed in shape, but is connected to a "deformable flexible front end" module.

[0074] Deformable Flexible Front End: This front end module is made of a shape memory alloy skeleton covered with medical-grade silicone, or it can be an inflatable flexible structure. Multiple pre-molded styles are available. Rectal / colonic version: Slender cone shape with a lubricating coating on the surface.

[0075] Vaginal / cervical type: Umbrella-shaped or saucer-shaped, which can fit the fornix when unfolded.

[0076] Nasal plug type: The curved shape of the nasal plug conforms to the anatomy of the nasal cavity.

[0077] Urethral type: an extremely thin straight tube with a smooth tip.

[0078] Modular interface structure: The main body of the cavity adapter release component is coupled to the deformable flexible front end through a micro soft connection quick interface. This interface ensures the sealing of the drug delivery flow path and the connection is smooth and stepless.

[0079] Workflow: Based on clinical needs (e.g., nasal administration), select the "nasal" flexible tip from the component package and connect it to the main body of the universal infusion tube with a click. Insert the assembled cavity adapter release component into the nasal cavity. The other end connects to the drive unit with the pre-assembled drug storage module via a standard Luer interface. Output is completed using preset infusion parameters. After use, discard the entire cavity adapter release component (including the tip), or discard only the tip (if the main body is designed for re-sterilization). This method greatly simplifies inventory; by simply replacing the tip module, the platform can be quickly adapted to various cavities such as the rectum, vagina, nasal cavity, and urethra, demonstrating the platform's modularity and compatibility.
