Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a drug delivery capsule. Background Art
[0002] The controlled release of drugs can improve the therapeutic effect of drugs and reduce side effects, especially for difficult-to-reach sections of the digestive tract. The use of capsule drug delivery solutions has received increasing attention. It has the advantages of being non-invasive, painless, having a wide coverage range, and precise drug controlled release. There are already some design schemes for capsule drug delivery devices, such as using a micro motor to push a piston to push out the drug in the drug chamber. This design has a high drug release control capability, can be used for multiple drug administrations, and the drug flow rate is controllable. However, the mechanical structure of the device is relatively complex, the power consumption is high, and it does not have a camera function. It can only roughly distinguish the digestive tract sections through a pH sensor and cannot make more precise drug release, such as administering drugs to lesions such as bleeding and ulcers.
[0003] There is also a method in which a gas chamber is set inside the capsule and pressurized gas is used to release the drug. The capsule is also equipped with a lens module to achieve precise release of the drug. However, since the capsule must be equipped with both a gas chamber and a drug chamber, as well as a drug discharge channel and a gas pressurization channel, the structural design is relatively complex and occupies a large space, which is not conducive to the miniaturization of the capsule.
[0004] Therefore, those skilled in the art are committed to developing a drug delivery capsule with a simple structure and precise drug release. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a drug delivery capsule with a simple structure and precise drug release.
[0006] To achieve the above-mentioned purpose, the present invention provides a drug delivery capsule comprising a detachably connected drug storage portion and a camera portion, wherein a soluble film is provided on one side of the drug storage portion connected to the camera portion. The drug storage portion is used to store drug powder, and the camera portion is used to capture images of the interior of the digestive tract. In the initial use state of the drug delivery capsule of this patent, the drug storage portion and the camera portion are connected together. When the drug delivery capsule enters the digestive tract and reaches a specific position, the drug storage portion and the camera portion are separated under command, and the soluble film is exposed and dissolved under the action of the liquid in the digestive tract, thereby releasing the drug in the drug storage portion and achieving precise drug delivery.
[0007] Preferably, the medicine storage part is provided with a magnet, and the camera part is provided with an electromagnetic control module, so that the medicine storage part and the camera part can be connected and separated by magnetic force under the cooperation of the electromagnetic control module and the magnet.
[0008] Preferably, the electromagnetic control module is electrically connected to the microprocessor module. The microprocessor module controls the electromagnetic control module, and when the drug storage portion and the imaging portion need to be connected, the electromagnetic control module generates a magnetic field that attracts the magnet, tightly connecting the two and forming a complete capsule. When the drug storage portion and the imaging portion need to be separated, the microprocessor module controls the electromagnetic control module to generate a magnetic field that repels the magnet in the drug storage portion, separating the drug storage portion and the imaging portion, thereby releasing the drug in the drug storage portion.
[0009] Preferably, the microprocessor module is also electrically connected to a radio frequency antenna module, an image processing module, and an LED light, and the image processing module is electrically connected to the lens module. This configuration enables image capture and transmission. The radio frequency antenna module transmits the captured images to an external receiver for viewing by a physician, facilitating lesion location identification and precise drug delivery. The specific image capture and transmission functions of the present invention are similar to those of existing capsule endoscopes and are therefore not further described.
[0010] Preferably, to facilitate filming, the lens module and the LED light are arranged on an end of the camera portion away from the soluble film.
[0011] Preferably, the microprocessor module is also connected to a battery to provide power to each module.
[0012] Preferably, the connecting surface of the camera part and the drug storage part is set as an intermediate shell, and the intermediate shell is conformally configured with the soluble film, so as to achieve a tight connection between the camera part and the drug storage part, maximize the use of internal space, and reduce the volume of the drug capsule.
[0013] Preferably, in order to enhance the stability and tightness of the connection between the camera part and the medicine storage part, the intermediate shell protrudes toward the soluble film, and the electromagnetic control module is arranged in the middle of the intermediate shell; the soluble film is concavely arranged, and the magnet is directly matched with the electromagnetic control module.
[0014] Preferably, to facilitate filming, the outer shell of the end of the camera portion away from the medicine storage portion is a transparent cover.
[0015] Preferably, the medicine storage portion further comprises a capsule bottom shell connected to the soluble film, and the capsule bottom shell and the soluble film enclose a medicine storage chamber.
[0016] The beneficial effects of the present invention are as follows: the present invention has a simple structure, which greatly reduces the complexity of the structural design of the drug delivery capsule, and can reduce the design cost and material cost of the product; the camera part allows the doctor or patient to observe the approximate position of the capsule in the digestive tract in real time, thereby achieving accurate release of the drug. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 2 This is a schematic diagram of the initial state structure of a specific embodiment of the utility model DETAILED DESCRIPTION
[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that in the description of the present invention, the orientation or positional relationship of the relevant indications is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific manner, and therefore cannot be understood as a limitation on the present invention.
[0020] like Figure 1 and Figure 2 As shown, a drug delivery capsule includes a detachably connected drug storage portion and an imaging portion, with a soluble film 12 provided on one side of the drug storage portion connected to the imaging portion. The drug storage portion also includes a capsule bottom shell 9 connected to the soluble film 12. The capsule bottom shell 9 and the soluble film 12 enclose a drug storage chamber 11. When the drug storage portion and the imaging portion are separated, the soluble film 12 is exposed to the digestive tract. Upon contact with the liquid in the digestive tract, the soluble film 12 dissolves and disappears, releasing the drug in the drug storage chamber 11, completing the drug delivery. The soluble film 12 can be made of a gastrointestinal soluble material such as hydropropyl methylcellulose or polyvinyl alcohol.
[0021] In this embodiment, the detachable connection is realized by: a magnet 10 is built into the medicine storage part, and an electromagnetic control module 8 is provided in the camera part. Figure 2 As shown, the microprocessor module 5 controls the electromagnetic control module 8 to generate a magnetic field that attracts the medicine storage magnet 10, so that the medicine storage part and the imaging part are tightly connected to form a complete capsule state.
[0022] The electromagnetic control module 8 is electrically connected to the microprocessor module 5. The microprocessor module 5 is also electrically connected to the radio frequency antenna module 7, the image processing module 4, the LED light 2, and the battery 6. The image processing module 4 is electrically connected to the lens module 1. The lens module 1 and the LED light 2 are located on the end of the camera unit away from the soluble film 12. The housing of the end of the camera unit away from the drug storage unit is a transparent cover 3. With this arrangement, after the patient swallows the medication capsule, the drug enters the digestive tract along with the medication capsule in the capsule drug storage chamber 11. During this period, the capsule's camera continuously captures the inner wall of the digestive tract and transmits the images in real time to an external receiver for the patient or doctor to view. When the capsule reaches the lesion area, the doctor issues a medication order to the medication capsule. The microprocessor module 5 controls the electromagnetic control module 8 to generate a magnetic field that repel each other with the magnet 10 in the drug storage unit, causing the medication storage unit and the camera unit to separate, dissolving the soluble film 12, and releasing the drug from the drug storage chamber, completing the entire medication task.
[0023] To enhance the tightness and stability of the connection, an intermediate housing 13 is provided at the interface between the camera unit and the drug storage unit. The intermediate housing 13 conforms to the soluble film 12. The intermediate housing 13 protrudes toward the soluble film 12. The electromagnetic control module 8 is located in the middle of the intermediate housing 13. The soluble film 12 is recessed, and the magnet 10 is aligned with the electromagnetic control module 8.
[0024] When the present invention is used, in the initial state, the drug storage part and the camera part are interconnected, and the patient can easily swallow the patented drug-delivery capsule. The drug capsule enters the digestive tract, during which the camera part continuously photographs the inner wall of the digestive tract and sends the image in real time to an external receiver for the patient or doctor to view. When it is found that the capsule reaches the lesion area, a drug-delivery command is sent to the capsule, the drug storage part and the camera part are separated, and the drug storage chamber releases the drug to complete the entire drug-delivery task.
[0025] The drug delivery capsule of this invention releases the drug by controlling the magnetic field to separate the drug compartment, significantly reducing the complexity of the capsule's structural design and potentially lowering product design and material costs. A built-in camera allows doctors or patients to observe the capsule's current position within the digestive tract in real time, enabling precise drug delivery.
[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
