Background

An endoscope is a common examination apparatus in the medical field, and is integrated with components such as an image sensor, an optical lens, light source illumination, a mechanical device and the like, and enters a human body through a natural duct of the human body or a manual opening when in use. Conventionally, since body fluid (gastric juice, intestinal juice, etc.) is adhered to the portion of the endoscope inserted into the human body, the endoscope can be reused only by strictly cleaning and sterilizing after each use, but the service life of the endoscope is reduced by repeated sterilization, and the sterilization process is time-consuming, so that a disposable endoscope sleeve has recently appeared, which is fixed on the outer tube of the insertion portion of the endoscope before use, and the endoscope sleeve can be discarded as medical waste after one use, so that the endoscope can be reused without sterilization, and the utilization rate of the endoscope is improved.

The structure of the disposable endoscope sleeve generally comprises a connector, a hose and a lens cover. In addition, the interface is in direct contact with the outer tube of the endoscope, if the diameter of the outer tube of the endoscope is smaller, the glass optical fiber in the endoscope is easily broken when the force is applied, so that the endoscope is damaged.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

As shown in fig. 1 to 5, a disposable endoscope sleeve comprises a joint 1, a hose 2 sleeved at the end of the joint 1, and a lens cover 3 connected to the end of the hose 2 far from the joint 1. The interface 1 is made of ABS, PVC and the like, the hose 2 is made of TPU, PVC and other thin-wall tubes with certain elasticity, the mirror cover 3 can be made of PC and other high-light-transmittance materials, and the joint of the three components can be fixed by means of dispensing and the like. The flexible tube 2 has elasticity and a length smaller than that of the outer tube 22 of the endoscope, so that the flexible tube 2 is in a stretched state after the disposable endoscope sleeve is assembled with the endoscope.

The interface 1 comprises a cylindrical end 10 and a tapered end 11, the diameter of the cylindrical end 10 of the interface 1 being larger than the diameter of the tapered end 11 of the interface. The cylindrical end 10 is provided with an end surface clamping part 15, the end surface clamping part 15 is clamped with a protruding part 21 arranged on the endoscope connector 20, and the end surface shape of the cylindrical end 10 of the interface 1 is complementary with the circumferential shape of the position where the protruding part 21 of the endoscope connector 20 is located, so that the endoscope sleeve can be smoothly screwed into the endoscope connector 20. The number of the protruding parts 21 is the same as the number of the end surface clamping parts 15, and the protruding parts are symmetrically arranged. A slight gap exists between the two projections 21 and the end face of the endoscope adapter 20. The cylindrical end 10 of the interface 1 is provided with a window 12 on a side surface thereof, the window 12 is a groove along the circumferential direction, and the position of the window 12 is located in front of the end surface clamping portion 15 in the axial direction and is the same as the end surface clamping portion 15 in the circumferential direction. At the location of the window 12 is provided a logo structure 14 in the shape of a double arrow.

The inner surface of the interface 1 is provided with a limiting part 13 for limiting the rotation of the interface 1 along the circumferential direction, and the limiting part 13 is positioned at a position connected with one side of the window 12 along the circumferential direction. The limiting part 13 prevents the interface 1 from rotating again in the circumferential direction after reaching the defined locking position.

When assembling the sleeve and the endoscope, the end face of the cylindrical end 10 of the adjusting port 1 is positioned in a position complementary to the shape of the endoscope connector 20, the endoscope outer tube 22 is inserted in alignment with the center of the port 1 of the disposable endoscope sleeve until the end face of the rear end of the cylindrical end 10 of the port 1 contacts the end face of the endoscope connector 20, and then the port 1 is rotated clockwise by 90 °, at this time, the two end face engaging portions 15 of the rear end of the endoscope sleeve port 1 are positioned in the foregoing minute gap and are abutted against the end faces of the two protruding portions 21 of the endoscope connector 20, and since the flexible tube 2 is in a stretched state, the end face engaging portions 15 are pulled toward the protruding portions 21 in the axial direction, so that the endoscope sleeve can be firmly fixed to the endoscope connector 20. No external force is applied to the outer tube 22 of the endoscope during the whole assembly process, so that the glass optical fiber inside the endoscope can be prevented from being damaged. When the endoscope sleeve is required to be detached, the interface 1 is only required to be rotated anticlockwise by 90 degrees to unlock, and the endoscope sleeve is taken down, so that the disassembly is very convenient and labor-saving. Above, also can anticlockwise lock, clockwise unblock, only need with spacing portion 13 of window 12 department adjust to opposite side can.

The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
