[0033] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0034] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Combine Figure 1 As shown, the present invention mainly relates to: a drug dispensing capsule, comprising a shell 1 and a partition plate 2 disposed within the shell 1. The partition plate 2 is circumferentially sealed to the inner wall of the shell 1. A drug compartment 13 is defined between one side of the partition plate 2 and the inner wall of the shell 1, and a device compartment 14 is defined between the other side of the partition plate 2 and the inner wall of the shell 1. The drug compartment 13 and the device compartment 14 are independently provided.

[0036] The medication capsule also includes a drug-loaded capsule 3 that is secured to the outer periphery of the partition plate 2 and extends into the drug chamber 13, and an injection structure 4 that extends from one side of the partition plate 2 into the drug-loaded capsule 3. The injection structure 4 is encased within the drug-loaded capsule 3. In this embodiment, the injection structure 4 is fixedly connected to the partition plate 2.

[0037] The drug enters through the injection structure 4 and is stored in the drug-loaded soft capsule 3 and enters the digestive tract along with the drug administration capsule. When it reaches the drug administration area, that is, the lesion area, it is released, thereby achieving accurate drug release.

[0038] In the radial direction of the drug-dispensing capsule, part of the drug-loaded soft capsule 3 is located between the injection structure 4 and the inner wall of the shell 1. In other words, part of the drug-loaded soft capsule 3 is sandwiched between the injection structure 4 and the inner wall of the shell 1. The injection structure 4 serves to connect the inner wall of the shell 1 and the drug-loaded soft capsule 3. The arrangement of the injection structure 4 allows the injection structure 4 to support the drug-loaded soft capsule 3 during the drug injection process, which has the advantages of convenient injection and good support effect.

[0039] Preferably, in the radial direction of the medication capsule, an injection portion 16 is formed at a position opposite to the shell 1 and the injection structure 4, and the injection structure 4 is aligned with the injection portion 16. During the drug injection process, the drug enters the drug-loaded soft capsule 3 through the injection portion 16 and the injection structure 4 in sequence.

[0040] Combine Figure 2 As shown, the injection structure 4 includes a fixing portion 41 disposed on one side of the partition plate 2 and a soft rubber plug 42 disposed in the fixing portion 41 . The injection portion 16 and the soft rubber plug 42 are disposed opposite to each other along the radial direction of the medication capsule.

[0041] Preferably, the axial direction of the soft rubber plug 42 is the radial direction of the shell 1, which facilitates the injection of medicine along the radial direction of the shell 1 and improves the convenience of operation.

[0042] The aforementioned injection portion 16 is configured as an injection through hole. It is understandable that the injection portion 16 may also be other structures, such as a tubular structure.

[0043] During the drug injection process, the drug enters the drug-loaded soft capsule 3 through the injection hole and the soft rubber plug 42. The elastic deformation of the soft rubber plug 42 blocks the perforation formed by the syringe passing through the soft rubber plug 42 during the drug injection process, thereby keeping the drug-loaded soft capsule 3 in a sealed state and preventing it from being contaminated by other liquid environments.

[0044] Furthermore, a drug-loaded through hole is opened on the wall of the drug-loaded soft capsule 3 at a position opposite to the soft rubber plug 42 to prevent the drug-loaded soft capsule 3 from being punctured during the drug injection process. At the same time, the setting of the soft rubber plug 42 will also block the drug-loaded through hole, so that the drug-loaded soft capsule 3 is in a relatively closed state.

[0045] Furthermore, the drug dispensing capsule, housing 1, device compartment 14, and partition plate 2 also includes a camera 51, a control unit, and a pump 53, all located within the compartment. The camera 51 is used to monitor the digestive tract and the drug release process in real time. The control unit includes circuit components such as a battery, a processor, and a wireless module. The pump 53 is a micropump, comprising a pump body, a pump driver, and a delivery pipeline.

[0046] Furthermore, the pump body 53 is fixed on the partition plate 2, the drug-loaded soft capsule 3 is sleeved on the outer periphery of the partition plate 2 and fixed with glue, and the control component is electrically connected between the camera 51 and the pump body 53. It has the advantages of compact structure and increased space utilization.

[0047] The pump body 53 is provided with a drug inlet 531 connected to the inside of the drug-loaded soft capsule 3, and the housing 1 is provided with a drug release port 15 connected to the outside of the housing 1. The drug dispensing capsule also includes a drug release pipe 6 connecting the drug inlet 531 and the drug release port 15. The drug release port 15 is arranged within the field of view of the camera 51.

[0048] Specifically, the pump body 53 draws the drug from the drug-loaded soft capsule 3 through the drug inlet 531 and ejects the drug from the drug release port 15 through the drug release pipe 6. The camera 51 can accurately observe the target position and direction of drug release, which has the advantage of precise control.

[0049] Combine Figure 3 As shown, the shell 1 includes a shell body 11, a medicine storage shell 12 arranged axially along the shell body 11 and sleeved on one end of the shell body 11, and the medicine storage shell 12 is sleeved and fixed on the outer periphery of one end of the shell body 11 and fixed by glue.

[0050] During assembly, the injection structure 4 is fixedly connected to the partition plate 2, and the drug-loaded capsule 3 is sleeved around the outer periphery of the partition plate 2, so that the injection structure 4 is enclosed in the drug-loaded capsule 3. The drug reservoir housing 12 and the shell body 11 are fixed to each other by glue. At this time, part of the drug-loaded capsule 3 is located between the injection structure 4 and the inner wall of the shell 1. The injection structure 4 serves to support the drug-loaded capsule 3, which has the advantages of facilitating injection and providing good support.

[0051] Furthermore, a medicine bin 13 is defined between one side of the partition plate 2 and the inner wall of the medicine bin shell 12 , and an equipment bin 14 is defined between the other side of the partition plate 2 and the inner wall of the shell body 11 , so as to improve the independence of the medicine bin 13 and the equipment bin 14 .

[0052] Preferably, the shell of the medicine chamber 13 is made of biocompatible hard shell plastic.

[0053] Furthermore, the shell 1 is also formed with a pressure balance hole 121 connecting the inside of the aforementioned medicine chamber 13 with the outside of the shell 1, wherein the pressure balance hole 121 is for maintaining the pressure balance in the medicine chamber 13: when the drug is released, the volume of the drug-loaded soft capsule 3 will gradually decrease, and the pressure balance hole 121 maintains the connection between the inside and the outside, ensuring the pressure balance in the medicine chamber 13, so that the drug release can be carried out continuously and smoothly.

[0054] In order to solve the above problems, the present invention also provides a drug administration capsule system.

[0055] Combine Figure 4As shown, a medication capsule system includes the medication capsule described above, and further includes a capsule holder 7 for detachably mounting the medication capsule. The capsule holder 7 is independently provided. The capsule holder 7 is designed to facilitate the injection of medication into the medication-loaded soft capsule 3 even when operated by a single operator. The capsule holder 7 is washable and reusable.

[0056] Combine Figure 5 As shown, the capsule holder 7 includes a support portion 71 at its bottom and an inclined slot 72 disposed above the support portion 71 and adapted to the outer wall of the housing 1. The inclined slot 72 is arc-shaped and has an inclined opening for mounting the housing 1. After the medication capsule is placed in the inclined slot 72, the angle of the medication capsule is adjusted by self-rotation, so that the injection portion 16 is disposed outside the inclined slot 72 and tilted upward. The inclined slot 72 maintains a constant angle, making it easier for the user to inject medication in a natural posture.

[0057] Furthermore, the support portion 71 is a plane formed by the bottom of the capsule holder 7 , which can be adsorbed on a horizontal and smooth tabletop.

[0058] Preferably, the capsule seat 7 tends to increase in size from top to bottom, thereby improving the stability of the capsule seat 7 and making the drug injection process proceed more smoothly.

[0059] Furthermore, the drug dispensing capsule system further comprises a syringe 8, which comprises a syringe body 81 and a needle 82 connected to the syringe body 81. The syringe body 81 can be a common syringe, such as a skin test syringe, connected to the needle 82.

[0060] The needle 82 sequentially penetrates the injection portion 16 and the injection structure 4, and the length of the needle 82 is less than the width of the housing 1. Preferably, the length of the needle 82 is less than 8 mm, reducing the risk of accidentally piercing the drug-loaded soft capsule 3, damaging the needle 82, or damaging the drug reservoir housing 12.

[0061] Combine Figure 6 As shown, the syringe 8 further includes an injection cavity formed by the syringe body 81 and connected to the injection through-hole. The needle 82 has through-holes 821 disposed on its head and side surfaces, respectively, that communicate with the injection cavity. To prevent the needle 82 from becoming clogged when piercing the injection structure 4, which would make it difficult to load the drug, the drug can flow out of the through-holes 821 disposed on the side surfaces, thereby improving the stability of the drug injection process.

[0062] Combine Figure 7As shown, the syringe 8 also includes a needle seat 83 connecting the needle 82 and the syringe body 81, a sleeve 84 arranged in the inner cavity of the needle seat 83, and a filter 85 arranged in the inner cavity of the sleeve 84, wherein the inner cavity of the needle seat 83 is connected to the injection cavity, and the surface of the filter 85 is arranged perpendicular to the axis of the sleeve 84. The mesh number requirement of the filter 85 matches the particle size specification requirement of the pump body 53. This ensures that oversized particles in the liquid medicine will not be loaded, reducing the risk of blockage during drug release. Of course, the user needs to know in advance the upper limit of the particle size supported by the pump body 53 so as to select the appropriate drug for injection. The needle 82 is a disposable item and is only used for capsule loading. One capsule can be equipped with 1 to 2.

[0063] The drug loading method of the drug dispensing capsule system is as follows:

[0064] 1. Take out the medicine capsule, turn on the machine, and run the pump 53 for several seconds to expel the air in the medicine-loaded soft capsule 3. At this time, the medicine-loaded soft capsule 3 can be seen shrinking;

[0065] 2. Place the medication capsule in the inclined groove 72 of the sterilized capsule holder 7;

[0066] 3. Adjust the capsule position so that the injection portion 16 is positioned outside the inclined slot 72;

[0067] 4. Replace the syringe body 81 filled with medicine with the corresponding needle 82;

[0068] 5. Use the syringe 8 to load the medication capsule with the drug. Align the needle 82 with the injection portion 16, the soft rubber plug 42, and the medication loading hole in sequence. Slowly push the piston of the syringe 8 to inject the drug into the medication-loaded soft capsule 3.

[0069] 6. Take out the medication capsule to complete the medication loading process of the medication capsule.

[0070] After the drug-loading capsule is completed by the syringe 8, a perforation is left when the needle 82 passes through the soft rubber plug 42. The elastic deformation of the soft rubber plug 42 blocks the perforation, so that the drug-loaded soft capsule 3 is in a sealed state.

[0071] Compared with the prior art, the drug administration capsule and drug administration capsule system provided by the present invention are achieved by fixing the drug-loaded soft capsule 3 on the outer periphery of the partition plate 2 and extending it into the medicine chamber 13, and extending the injection structure 4 from one side of the aforementioned partition plate 2 into the drug-loaded soft capsule 3, so that part of the drug-loaded soft capsule 3 is clamped between the injection structure 4 and the inner wall of the shell 1, and the injection structure 4 serves to connect the inner wall of the shell 1 and the drug-loaded soft capsule 3. In the radial direction of the drug administration capsule, an injection part 16 is formed at a position where the shell 1 and the injection structure 4 are opposite to each other. Through the setting of the injection structure 4, the injection structure 4 supports the drug-loaded soft capsule 3 during the injection of the drug, and the drug enters the drug-loaded soft capsule 3 through the injection part 16 and the injection structure 4 in turn, which has the advantages of good support effect, easy insertion, smooth injection process, and stable and reliable structure.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
