Abstract

A capsule endoscope for observing the conditions inside a patient'"'"'s digestive tract system includes a capsular housing, a substrate, and a plurality of metal-insert molded contacts. The capsular housing defines a sealed inner space and has an outer surface. The substrate is arranged in the sealed inner space of the capsular housing and is mounted with at least an electronic element provided thereon. The metal-insert molded contacts are embedded in the capsular housing at predetermined positions thereof and each includes a contact base and an exposed contact portion formed on the contact base. The contact bases each have a connecting section extended into the sealed inner space of the capsular housing to electrically connect to the substrate. The exposed contact portions each have a front surface exposed from the outer surface of the capsular housing for contacting with a signal contact correspondingly provided on a capsule holder that holds the capsular housing thereto.

Claims

1. A capsule endoscope, comprising:

a capsular housing defining a sealed inner space-and having an outer surface;

a substrate being arranged in the sealed inner space of the capsular housing at a predetermined position thereof, and mounted with at least an electronic element provided thereon; and

a plurality of metal-insert molded contacts being embedded in the capsular housing at predetermined positions thereof, and each of the metal-insert molded contacts including;

a contact base having a connecting section, which is radially extended into the sealed inner space of the capsular housing to electrically connect to the substrate; and

an exposed contact portion being formed on the contact base and having a front surface exposed from the outer surface of the capsular housing;

whereby when the capsular housing is held in a capsule holder, the exposed contact portions are in contact with a signal contact correspondingly provided on the capsule holder.

2. The capsule endoscope as claimed in claim 1, further comprising a control unit electrically connected to the metal-insert molded contacts to switch a high impedance status between the metal-insert molded contacts and the substrate.

3. The capsule endoscope as claimed in claim 1, wherein the metal-insert molded contacts each have a layer of metal material coated thereon.

4. The capsule endoscope as claimed in claim 1, wherein the contact bases of the metal-insert molded contacts each are an L-shaped sheet member.

5. The capsule endoscope as claimed in claim 1, wherein the contact bases of the metal-insert molded contacts each are a flexible circuit board.

6. The capsule endoscope as claimed in claim 1, wherein the exposed contact portions of the metal-insert molded contacts are formed on the contact bases by way of stamping.

7. The capsule endoscope as claimed in claim 1, wherein the exposed contact portions of the metal-insert molded contacts are formed on the contact bases by way of riveting.

8. The capsule endoscope as claimed in claim 1, wherein the exposed front surfaces of the exposed contact portions are flush with the outer surface of the capsular housing.

9. A capsule endoscope, comprising:

a capsular housing defining a sealed inner space and having an outer surface;

a substrate being arranged in the sealed inner space of the capsular housing at a predetermined position thereof, and having a sensing circuit provided thereon; and

a plurality of metal-insert molded contacts being embedded in the capsular housing at predetermined positions thereof, and each of the metal-insert molded contacts including;

a contact base having a connecting section, which is radially extended into the sealed inner space of the capsular housing to electrically connect to the sensing circuit on the substrate; and

an exposed contact portion being formed on the contact base and having a front surface exposed from the outer surface of the capsular housing;

wherein there is a high impedance existed among the metal-insert molded contacts; and

the metal-insert molded contacts contact and sense external environmental signals around a position at where the capsular housing is located; and

the sensed external environmental signals are sent to the sensing circuit on the substrate via the exposed contact portions and the contact bases of the metal-insert molded contacts.

10. The capsule endoscope as claimed in claim 9, further comprising a control unit electrically connected to the metal-insert molded contacts to switch a high impedance status that existed between the metal-insert molded contacts and the substrate.

11. The capsule endoscope as claimed in claim 9, wherein the metal-insert molded contacts each have a layer of metal material coated thereon.

12. The capsule endoscope as claimed in claim 9, wherein the contact bases of the metal-insert molded contacts each are an L-shaped sheet member.

13. The capsule endoscope as claimed in claim 9, wherein the contact bases of the metal-insert molded contacts each are a flexible circuit board.

14. The capsule endoscope as claimed in claim 9, wherein the exposed contact portions of the metal-insert molded contacts are formed on the contact bases by way of stamping.

15. The capsule endoscope as claimed in claim 9, wherein the exposed contact portions of the metal-insert molded contacts are formed on the contact bases by way of riveting.

16. The capsule endoscope as claimed in claim 9, wherein the exposed front surfaces of the exposed contact portions are flush with the outer surface of the capsular housing.

17. The capsule endoscope as claimed in claim 9, wherein the external environmental signals sensed by the metal-insert molded contacts comprises at least one of a temperature signal, a pressure signal, and a pH signal.
