Definitions

  • the invention belongs to medical equipment, and in particular relates to a capsule endoscope. Background technique
  • capsule endoscopes Since 1995, there have been hundreds of patent applications in various countries, and the research and development of capsule endoscopes has become a boom. Its typical structure is: a light body, an objective lens, a CMOS or CCD camera, a signal generator, and an antenna as the main body. Powered by batteries or capacitors, wrapped in a capsule-shaped, transparent case. But they are all made up of high-tech devices, making them expensive to make. In addition, the battery or capacitor for power supply is fixed in the housing, and the entire capsule endoscope is only used for one time. It is discarded after use, and the cost is too high, so the patient has to pay too much. For developing countries, especially China, India and other populous countries, it can only be applied to a small number of people. Summary of the invention

  • the disposable protective jacket according to the present invention has a capsule structure adapted to the shape of the shell; part or all of the disposable protective jacket can be made of materials with biocompatibility, electricality, chemical stability, and transparency; A dielectric layer may also be provided between the transparent front half of the disposable protective outer surface and the outer surface of the housing to reduce the loss of light reflected between the two surfaces.
  • the present invention is an improvement and supplement to various existing capsule endoscopes, and proposes a battery that can be replaced and covered on the outer surface of the entire capsule endoscope casing to protect the outer casing at one time, so that the lens body in the protective casing can be more Repeated use ensures that the capsule endoscope housing does not touch the patient's cavity, and relieves the patient from worrying about hygiene.
  • the expensive capsule endoscope body itself is no longer a single-use, but a disposable protective jacket that is placed on the outside for protection. In this way, under the premise of ensuring safety, the cost of medical examinations is greatly reduced, which is very suitable for China's national conditions. The low cost is more conducive to using multiple capsule endoscopes to enter the digestive tract at a certain distance. Multiple microscopy is helpful to reduce the rate of missed diagnosis.

  • the disposable protective jacket according to the present invention has a capsule structure adapted to the shape of the casing 10; part or all of the disposable protective jacket can be biocompatible, electrical, chemically stable, transparent Materials, such as medical polyvinyl chloride (the front half 9 of the disposable protective jacket in this embodiment is a transparent body, and the rear half 7 may be a non-transparent body).
  • the production and installation of the present invention is based on the existing capsule endoscope, and the position where the battery 4 is placed is set to An opening 12 is convenient for loading and unloading the battery 4.
  • a capsule endoscope with such improved structure or only a disposable protective jacket can be swallowed into a patient's body, or one or more capsule endoscopes with such improved structure can be separated on a patient. Continuous swallowing at a certain distance to reduce the rate of missed microscopy.
  • the above-mentioned capsule endoscope after use requires the patient to be discharged from the body, and then rinsed and recovered by the hospital.
  • the outer disposable protective jacket is peeled off, and the front surface 13 of the casing 10 is cleaned with a solvent (for battery-powered Replacement battery). Put on a disposable transparent protective jacket, and finally put it into a device with considerable magnetic force at a certain location. Turn off the power with a magnetic switch for next use.
  • the capsule endoscope does not contact the cavity of any patient, so the capsule endoscope can be used repeatedly and repeatedly. Because they are not contaminated, patients do not feel unhygienic. The patient only touches the jacket, because this protective jacket is disposable and completely avoids all cross-infection and unhygienic situations.
  • Embodiment 1 It is structurally different from Embodiment 1 in that it can also be on the inner surface of the front half of the disposable protective jacket
  • a dielectric layer 11 is provided between 14 and the outer surface 13 of the casing 10 to reduce the loss of light reflected between the two surfaces. Specifically: After dropping a drop of transparent viscous medium 15 on the inner surface 14 of the front half of the disposable protective jacket, the medium 15 is in contact with the outer surface 13 of the housing 10 of the capsule endoscope body. The halves 9, 7 (Fig. 3) continue to apply axial pressure after the set, squeezing the medium to form a transparent medium layer 11. The refractive index of the dielectric layer 11 is close to that of the housing 10 and the front half 9 of the disposable protective cover, thereby reducing the loss of light caused by the increased reflection on the two interfaces after the disposable protective cover is added. .
  • This drop of transparent and viscous medium 15 may be a silicone oil or the like used in a high-power microscope.
  • the size of the drop is determined by the diameter of the ball head at the front of the dipstick.
  • the amount of the medium dropped is to ensure that the area of the formed dielectric layer 11 is in degrees required to cover the angle of view.
  • the tightness of the set of the two front and rear halves 9, 7 of the disposable protective jacket depends on the two interfaces: the outer surface 8 of the disposable protective jacket near the seal and the disposable protective jacket near the seal. Fit accuracy of the inner surface 14 of the front half. With the increase of the axial pressure of the front and back halves 9 and 7 of the disposable protective jacket, the outer surface 8 of the rear half of the disposable protective jacket near the seal and the disposable protective jacket near the seal are made.
  • the gap of the inner surface 14 of the front half approaches zero, thereby meeting the requirements of sealing, because the mating parts of the front and back halves 9 and 7 of the disposable protective cover have sufficient friction angles to ensure that the two cannot be separated
  • various capsule endoscopes basically use a camera system (a light-emitting body for illumination, an objective lens, a CMOS or CCD camera) to send a signal of an image of an object through a signal processor and an antenna to the outside of the body.
  • a camera system a light-emitting body for illumination, an objective lens, a CMOS or CCD camera
  • the battery provides energy, but when the battery is depleted, work will stop (at best, the small intestine can only be diagnosed). As the battery cannot be replaced, all microelectronic devices included in the complete capsule endoscope will be discarded.

Abstract

L'invention concerne un appareil médical, et plus spécifiquement un type d'endoscope à forme de capsule. Selon cette invention, une ouverture (12) est ajoutée sur le corps (10) de l'endoscope à forme de capsule connu pour le changement des piles. De plus, une enveloppe de protection jetable est située à l'extérieur du corps (10). Cette enveloppe de protection jetable est en forme de capsule par rapport à la forme du corps. Une couche médiane (11) peut être placée entre la surface intérieure (14) de la partie avant transparente (9) et la surface extérieure (13) du corps (10) afin de diminuer la perte de lumière due à l'ajout de l'enveloppe. Les piles et l'enveloppe de protection de cette invention ne doivent être changés qu'une fois pour chaque examen. Ainsi, cet endoscope à forme de capsule peut être réutilisé, il permet de diminuer le coût de l'examen sans risque d'infection iatrogène et peut facilement être diffusé dans la population. Grâce à son faible coût, un sujet peut avaler en continu plusieurs endoscopes à forme de capsule à un intervalle donné, de façon à réduire le taux de diagnostic erroné.
