Abstract

This application belongs to a medical appliance, in particular to a capsule endoscope. The utility model is an existing capsular type shell added with an opening capable of changing batteries, and the exterior of the shell is equipped with a one time only protecting external tube. The one time only protecting external tube is a capsule structure corresponding to the shell configuration. A dielectric layer can be arranged between the transparent front half-part of the one time only protecting external tube and the exterior surface of the shell. So the light loss caused by increasing the external tubes can be reduced. By adopting batteries replaceable technology of this application and the one time only protecting jacket structure, each time of checking only needs to change the batteries and the external tube one time. So the high fabricating cost capsule endoscope can be repeatedly used. So the checking cost price is hugely reduced without happening nosocomial infection. The utility model is convenient to popularize and pervade to the extensive mass. Because the cost price is cheap, so a plurality of such capsule endoscopes can be used by a patient at a distance to continuous swallow checking, so the microscopy rate of missed diagnosis is reduced.

The specific embodiment

Embodiment 1

As Fig. 1, Fig. 2 and shown in Figure 3, the application comprises housing 10, battery 4, luminous body 1, object lens 2, CMOS or ccd video camera 3, signal projector 5, antenna 6, described battery 4, luminous body 1, object lens 2, video camera 3, signal projector 5, antenna 6 place in the housing 10, housing 10 is the capsule-type structure, partly or entirely is the transparent body; On described capsule-type housing 10, be provided with in order to change the opening 12 of battery 4; Be provided with disposable protection overcoat in housing 10 outsides, described disposable protection overcoat is made up of first half 9 and latter half of 7;

Wherein: the described disposable protection overcoat of the application is the capsule structure that adapts with housing 10 profiles; Partly or entirely can adopting of described disposable protection overcoat has biocompatibility, the material of electricity, chemical stability, the transparency; as (first half 9 of the disposable protection overcoat of present embodiment are the transparent body, and latter half of 7 can be opaque body) such as medical polyvinyls.

The application's making and installation are on the basis of existing capsule endoscope, will settle the position of battery 4 that an opening 12 of being convenient to adorn power taking pond 4 is set.To do following preparation before use: the new battery 4 of packing into, and former and later two half ones 9 of disposable protection overcoat that will be as shown in Figure 3 dock with 7 and overlap the outside that is enclosed in this capsule endoscope housing 10.

When clinical: available one piece of capsule endoscope that has improved structure like this or only installed disposable protection overcoat additional is swallowed in patient's body; also available one piece or many pieces capsule endoscope that has improved structure is like this swallowed continuously in that patient is separated by a distance on one's body, to reduce the microscopy rate of missed diagnosis.Above-mentioned capsule endoscope after the use, need the patient to wait to excrete after, clean through preliminary flushing, regain by hospital, peel off outside disposable protection overcoat, clean the front surface 13 (to battery-powered replacing battery) of housing 10 with solvent.Put disposable transparent protection overcoat, be enclosed at last in the device that certain corresponding site has suitable magnetic force, by the magnetic switch powered-down in order to using next time.

The application is owing to the protection of disposable protection overcoat, and capsule endoscope does not contact any patient's tract, thus but just repeated multiple times use of capsule endoscope.Because not contaminated, the patient does not have antihygienic sensation yet.The just overcoat of patient's contact because this protection overcoat is disposable, has avoided all cross infections and unhygienic situation to take place fully.

Embodiment 2

Structurally difference from Example 1 is: also can establish dielectric layer 11 between the first half inner surface 14 of described disposable protection overcoat and housing 10 outer surfaces 13, to reduce the light loss of reflecting between two surfaces.Be specially:

14 transparent viscous mediums 15 of first half inner surface at disposable protection overcoat; this medium 15 is with after housing 10 outer surfaces 13 of capsule endoscope mirror body contact; because former and later two half one 9,7 (Fig. 3) continuation axial pressure behind suit of disposable protection overcoat; this medium is crowded thin, form layer of transparent dielectric layer 11.The refractive index of the first half 9 of the refractive index of this dielectric layer 11 and housing 10 and disposable protection overcoat is approaching, thereby has reduced light because increased the reflection that is increased behind the disposable protection overcoat and the loss that produces on two interfaces.This transparent viscous medium 15 can be the used things such as silicone oil of high power microscope, and the size of its amount is by dipping in the size decision of getting the forward bulb diameter of device.The medium amount of being dripped is for guaranteeing that formed dielectric layer 11 areas are can cover the needed area of angle of visual field degree of being substantially.The sealing of the suit of former and later two

half ones

9,7 of disposable protection overcoat depends on this two interfaces: latter half of outer surface 8 near sealing part of promptly disposable protection overcoat and the quality of fit that is positioned near the first half inner surface 14 of the disposable protection overcoat of sealing part.Increase along with the axial compressive force of former and later two half ones 9 of the disposable protection overcoat of execute and 7; make latter half of outer surface 8 near sealing part of disposable protection overcoat and the gap that is positioned near the first half inner surface 14 of the disposable protection overcoat of sealing part level off to zero; thereby reach the requirement of sealing; because former and later two

half ones

9 and 7 mating parts of disposable protection overcoat have enough angle of frictions, guaranteed that the two can not natural separation.

Comparative example

In the prior art various capsule endoscopes be substantially by camera system (for luminous body, object lens, CMOS or the ccd video camera of illumination) with the picture of captured object, by signal processor and antenna signal is sent to external, donor external system reception.Battery provides the energy, exhausts but work as the energy content of battery, and work just will stop (examination of small intestinal stage can only being finished at most).Because battery can not be changed, all included microelectronic devices of a complete set of capsule endoscope all will be discarded.When powering with capacitor certainly, by radio frequency external to its charging do not have a this problem, but still the disposable problem that exists capsule endoscope mirror body to use, the application's disposable external-cover has then solved this key technology, and it can repeatedly be used.
