Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a convenient-to-use gastroscope medication delivery device and method. Background Art

[0002] Gastroscopy is a common invasive examination and a good way to diagnose gastrointestinal diseases. However, it will cause obvious discomfort during the examination and there are serious complications such as infection, bleeding, and perforation. Painless gastroscopy also has the risk of anesthesia accidents. The magnetically controlled capsule gastroscopy can achieve high visualization of the gastric mucosa due to its accurate control and positioning. The diagnostic accuracy is highly consistent with that of traditional gastroscopy. After examining the stomach, the small intestine can be further examined. It is painless and non-invasive, does not require anesthesia and disinfection, is simple and comfortable, and has lower risks.

[0003] The magnetically controlled capsule gastroscopy system is mainly composed of four parts: a capsule endoscope, an image recorder, a software imaging workstation and a magnetic field control device. The control principle is mainly to set a magnet inside the capsule gastroscopy, and then control the movement trajectory of the capsule gastroscopy in the subject's body through an external magnetic field, that is, to apply a magnetic field around the subject and drive the capsule with a magnetic moment to move in the human digestive system by manipulating the rotation and translation of the magnetic field, so that medical staff can comprehensively observe the gastrointestinal tract from all directions.

[0028] 6. The present invention provides an annular reinforcement frame, so that multiple annular reinforcement frames are fixed on the inner wall of the power capsule, which can play a positioning role for the micro-guide rail, improve the connection strength of the micro-guide rail inside the power capsule, and stably install the micro-guide rail on the sealing partition, so that the micro-guide rail can maintain balance during the movement of the electric slider, and prevent the micro-guide rail from shaking and affecting the release of the medicine;

[0029] 7. The present invention provides a gelatin film so that the gelatin film can play a protective role on the drug delivery nozzle. On the one hand, it can prevent dust and bacteria from entering the medicine storage capsule through the drug delivery nozzle and mixing into the medicine before the patient swallows the medicine.

[0049] The power assembly is used to squeeze the medicine in the medicine storage capsule 3 so that the medicine is sprayed to the outside from the medicine spraying micro-holes 501 on the drug delivery nozzle 5. Figure 5 , Figure 6 As shown, the power assembly includes a micro guide rail 7 disposed inside the power capsule 2, the micro guide rail 7 is fixedly mounted on the top of the sealing partition 6, an electric slider 8 is driven and mounted on one side of the micro guide rail 7, and a traveling frame 9 is fixedly mounted on the side wall of the electric slider 8, as shown in FIG. Figure 7 As shown, a power frame 10 is fixedly mounted on one end of the traveling frame 9. Figure 8 As shown, a sealing sliding hole 601 is provided on the top of the sealing partition 6. Figure 5As shown, the bottom end of the power frame 10 passes through the sealing slide hole 601 and extends to the inside of the folding tube 4 and is fixedly installed with a medicine pushing plate 11. In this embodiment, the power frame 10 is located at the axial position of the power capsule 2 and the medicine storage capsule 3. A sealing sleeve is provided at the joint between the power frame 10 and the sealing slide hole 601. The medicine pushing plate 11 is made of soft rubber material. The medicine pushing plate 11 fits with the inner wall of the medicine storage capsule 3 to prevent the medicine inside the medicine storage capsule 3 from penetrating into the power capsule 2. Specifically, by setting the power component, the medical staff can control The magnetically controlled capsule gastroscope 1 carries the drug-delivering capsule and moves close to the affected part, and then controls the electric slider 8 inside the power capsule 2 to start sliding along the micro-guide rail 7, thereby driving the power frame 10 to slide in the sealed sliding hole 601 through the traveling frame 9, so that the drug-pushing plate 11 at one end of the power frame 10 squeezes the medicine in the drug storage capsule 3, so that the medicine is directly ejected from each drug-spraying micro-hole 501 under the action of pressure, and then the drug liquid is sprayed on the affected part, realizing direct drug delivery, and solving the problem that the traditional capsule gastroscope can only be used for observation but not for drug delivery;

[0050] like Figure 3 As shown, first docking plates 12 are fixedly installed on both sides of the medicine storage capsule 3, magnetic metal plates 13 are fixedly installed on the side walls of the first docking plates 12, and outer shells 15 are fixedly installed on the side walls of the first docking plates 12. The two magnetic metal plates 13 are respectively located inside the two outer shells 15. Figure 2 As shown, the second docking plates 14 are fixedly installed on both sides of the magnetically controlled capsule gastroscope 1, and the positions of the two first docking plates 12 correspond to the positions of the two second docking plates 14 respectively. The side walls of the second docking plates 14 are provided with docking grooves 1401 adapted to the outer shell 15, and the sides of the docking grooves 1401 are provided with docking guide angles 1402.

In this embodiment, the relative rotation direction of the two adjacent steering plates 17 is on the same vertical plane as the straight line where the first docking plate 12 and the second docking plate 14 are located; specifically, by setting the folding tube 4, when the patient swallows the device, the magnetically controlled capsule gastroscope 1 and the drug-delivery capsule are connected through the folding tube 4, and the magnetically controlled capsule gastroscope 1 does not contact the power capsule 2, thereby facilitating the patient to swallow the device. Before directly administering the drug to the affected area, the medical staff controls the magnetically controlled capsule gastroscope 1 to move up and down, so that a relative displacement occurs between the magnetically controlled capsule gastroscope 1 and the power capsule 2 and the drug storage capsule 3. The limiting rings 16 and the steering plates 17 in the folding tube 4 cooperate with each other to limit the bending direction and the shape of the folding tube 4 after bending. When the folding tube 4 is bent, the second docking plate 14 on the magnetically controlled capsule gastroscope 1 and the power capsule 2 are The first docking plate 12 on the capsule 2 is always on the same vertical plane, so that the folding tube 4 can only bend toward the position of the first docking plate 12 and the second docking plate 14, so that the magnetically controlled capsule gastroscope 1 and the power capsule 2 finally contact each other. At this time, the first docking plate 12 and the second docking plate 14 remain aligned, and the magnetic metal plate 13 on the power capsule 2 drives the outer shell 15 to be stuck into the docking groove 1401 along the docking guide angle 1402 under the magnetic attraction of the magnet inside the magnetically controlled capsule gastroscope 1, so that the first docking plate 12 and the second docking plate 14 are fitted together, and then the magnetically controlled capsule gastroscope 1 and the power capsule 2 are folded and assembled, so that the direction of the camera device of the magnetically controlled capsule gastroscope 1 is parallel to the direction of the drug administration nozzle 5. At this time, the position and direction of the drug administration nozzle 5 can be accurately controlled by controlling the movement of the magnetically controlled capsule gastroscope 1. While the magnetically controlled capsule gastroscope 1 photographs the affected area, the power component is controlled to push out the medicine in the medicine storage capsule 3 and spray it on the affected area, thereby achieving precise drug administration.

[0055] like Figure 4As shown, a gelatin film 24 is fixedly installed at the bottom of the drug storage capsule 3. In the present embodiment, the gelatin film 24 is mainly made of food-grade medicinal gastric-soluble gelatin, which can be quickly dissolved in the stomach, and the drug delivery nozzle 5 is located inside the gelatin film 24. Specifically, by setting the gelatin film 24, the outside of the drug delivery nozzle 5 is wrapped with a layer of gelatin film 24, which can protect the drug delivery nozzle 5. On the one hand, it can prevent dust and bacteria from entering the drug storage capsule 3 through the drug spraying micropores 501 on the drug delivery nozzle 5 and mixing into the medicine in the process of taking out the device and swallowing by the patient.

Location of the affected part: The medical staff controls the magnetically controlled capsule gastroscope 1 to move in the patient's stomach through an external magnetic field control device, and observes the patient's stomach in real time through a software imaging workstation and an image recorder worn by the patient until the affected part is found:

[0060] S3. Folding of the device: The medical staff controls the magnetically controlled capsule gastroscope 1 and the power capsule 2 to contact each other, and the magnetic metal plate 13 is inserted into the docking groove 1401. The magnetically controlled capsule gastroscope 1 and the power capsule 2 are folded and assembled so that the direction of the camera device of the magnetically controlled capsule gastroscope 1 is parallel to the direction of the drug delivery nozzle 5:

[0061] S4. Precise drug delivery: The position and direction of the drug delivery nozzle 5 are precisely controlled by controlling the movement of the magnetically controlled capsule gastroscope 1. While the magnetically controlled capsule gastroscope 1 is photographing the affected area, the medicine is squeezed by the power component so that the medicine is sprayed on the affected area under pressure, thereby achieving direct and precise drug delivery:

[0062] S5. Device excretion: After the drug administration is completed, the medical staff controls the magnetically controlled capsule gastroscope 1 to separate from the power capsule 2, and the gelatin block 18 gradually dissolves in the patient's body, so that the magnetically controlled capsule gastroscope 1, the folding tube 4 and the drug administration capsule are separated from each other, and the device is decomposed into multiple small parts, which is convenient for the patient to excrete the device later.

[0063] In summary: before use: the patient first wears the image recorder and lies on the bed, and the medical staff takes the device out of the package, cuts the first rubber sheet 22, and uses the cut first rubber sheet 22 to tear off the first soft rubber shell 21 from one side of the magnetically controlled capsule gastroscope 1 and the power capsule 2, and then cuts the second rubber sheet 26 and tears the second soft rubber shell 25 from the bottom of the drug storage capsule 3, and gives the device to the patient to drink water and swallow into the stomach;

[0064] During use: the medical staff controls the movement of the magnetically controlled capsule gastroscope 1 in the patient's stomach through the external magnetic field control device in cooperation with the controllable magnet inside the magnetically controlled capsule gastroscope 1, and observes the patient's stomach condition in real time through the software imaging workstation and the image recorder worn by the patient until the affected area is found. The medical staff controls the magnetically controlled capsule gastroscope 1 to carry the medication capsule and move close to the affected area. The medical staff controls the magnetically controlled capsule gastroscope 1 to move up and down, so that a relative displacement occurs between the magnetically controlled capsule gastroscope 1 and the power capsule 2 and the drug storage capsule 3. The limiting ring 16 and the steering plate 17 in the folding tube 4 cooperate with each other to limit the bending direction and the shape of the folding tube 4 after bending. When the folding tube 4 is bent, the second docking plate 14 on the magnetically controlled capsule gastroscope 1 and the first docking plate 12 on the power capsule 2 are always on the same vertical plane, so that the folding tube 4 can only bend toward the position of the first docking plate 12 and the second docking plate 14, so that the magnetically controlled capsule gastroscope 1 and the power capsule 2 finally contact each other. At this time, the first docking plate 12 and the second docking plate 14 are in contact with each other. The two docking plates 14 remain aligned, and the magnetic metal plate 13 on the power capsule 2 drives the outer shell 15 to be stuck into the docking groove 1401 along the docking guide angle 1402 under the magnetic attraction of the magnet inside the magnetically controlled capsule gastroscope 1, so that the first docking plate 12 and the second docking plate 14 are fitted together, and then the magnetically controlled capsule gastroscope 1 and the power capsule 2 are folded and assembled, so that the direction of the camera device of the magnetically controlled capsule gastroscope 1 is parallel to the direction of the drug administration nozzle 5. At this time, the position and direction of the drug administration nozzle 5 can be accurately controlled by controlling the movement of the magnetically controlled capsule gastroscope 1. While the magnetically controlled capsule gastroscope 1 photographs the affected part, the electric slider 8 inside the power capsule 2 is controlled to start sliding along the micro guide rail 7, so that the power frame 10 is driven to slide in the sealing slide hole 601 through the traveling frame 9, so that the medicine pushing plate 11 at one end of the power frame 10 squeezes the medicine in the medicine storage capsule 3, so that the medicine is directly ejected from each medicine spraying microhole 501 under the action of pressure, and then the medicine liquid is sprayed on the affected part, realizing direct and precise drug administration;

[0065] After use: After the examination and medication are completed, the medical staff controls the magnet inside the magnetically controlled capsule gastroscope 1 to weaken the magnetism, so that the magnetically controlled capsule gastroscope 1 and the power capsule 2 are separated under the action of gravity, and then the gelatin blocks 18 at both ends of the folding tube 4 are gradually dissolved under the action of the patient's own digestive system, so that the magnetically controlled capsule gastroscope 1, the folding tube 4 and the medication capsule are separated from each other, and the device is decomposed into multiple small parts, which is convenient for the patient to excrete the device later.
