DETAILED DESCRIPTION

[0026] The present invention is further described below through specific implementation methods.

[0027] Reference Figures 1 to 5The utility model provides an anti-splash device for an endoscope biopsy port, which is arranged on the biopsy port 2 of an endoscope 1, and includes a bottom tube 3, an anti-splash head 4 and a blocking head 5. The bottom tube 3 is arranged on the biopsy port 2, the anti-splash head 4 is arranged on the bottom tube 3, the blocking head 5 is arranged on the side of the anti-splash head 4 away from the bottom tube 3, and a lifting handle 50 is provided on the blocking head 5.

[0028] The bottom tube 3 has an active cavity 30 that runs through from top to bottom. The active cavity 30 is connected to the biopsy port 2. A tightening section 31 is formed in the active cavity 30, with the opening gradually decreasing toward the side of the biopsy port 2. An insertion groove 32 is formed between the side wall of the tightening section 31 and the tube wall of the bottom tube 3. The bottom tube 3 is arranged on the biopsy port 2 through the insertion groove 32 so that the tightening section 31 partially extends into the biopsy port 2.

[0029] The anti-splash head 4 is detachably mounted on the bottom tube 2 and is movable between a sealed position and an open position. The anti-splash head 4 is a double-layer tubular structure having an inner tube 40 and an outer tube 41. The inner tube 40 and the outer tube 41 are spaced apart and open at only one end. The splash-proof head 4 also includes a center hole 42, a blocking portion 43, a first splash-proof plate 44, a second splash-proof plate 45 and an anti-slip strip 46. The center hole 42 is opened on the inner tube 40 and the center hole 42 passes through the splash-proof head 4 up and down. Three embedded grooves 420 are formed on the inner wall of the center hole 42 and are parallel to and spaced apart along the axial direction of the center hole 42. The first splash-proof plate 44, the second splash-proof plate 45 and the blocking portion 43 are sequentially arranged in the three embedded grooves 420, and the blocking portion 43 at least partially protrudes from the center hole 42. When the splash-proof head 4 is arranged on the bottom tube 3, the center hole 42 is connected to the active cavity 30 and the part of the blocking portion 43 protruding from the center hole 42 extends into the active cavity 30. When the splash-proof head 4 is in a sealed position, the blocking portion 43 passes through the tightening section 31 and is tightened by the tightening section 31 to form a sealed state. The gap between the outer tube 41 and the inner tube 40 is greater than the wall thickness of the bottom tube 3. The inner wall of the outer tube 41 is formed with an internal thread, and the outer wall of the bottom tube 3 is formed with an external thread. The anti-splash head 4 is detachably attached to the bottom tube 3 via a threaded connection. The anti-slip strip 46 is provided on the outer circumference of the outer tube 41.

[0030] The blocking portion 43 includes a mounting plate 430 and multiple blocking plates 431. The blocking plates 431 are evenly arranged along the circumference of the mounting plate 430. The mounting plate 430 is installed in the embedding groove 420 so that the blocking plates 431 protrude from the central hole 42. The blocking plates 431 can be tightened by the tightening section 31 to form a sealed conical structure. The diameter of the tightening section 31 at its largest opening is larger than the fully expanded diameter of the blocking plates 431. At its smallest opening, the blocking plates 431 can be fully tightened to form a sealed cone.

[0031] The first splash guard 44 includes a first mounting portion 440 and a first splash guard 441. The first mounting portion 440 is arranged on the outer peripheral surface of the first splash guard 441. The first splash guard 44 is detachably arranged on the embedding groove 420 through the first mounting portion 440. The first splash guard 441 is made of an elastic material and a cross groove 442 is provided on the first splash guard 441. The first splash guard 441 can be opened or closed along the cross groove 442.

[0032] The second splash guard 45 includes a second mounting portion 450 and a second splash guard 451. The second mounting portion 450 is arranged on the outer peripheral surface of the second splash guard 451. The second splash guard 45 is detachably arranged on the embedding groove 420 through the second mounting portion 450. The second splash guard 451 includes a plurality of elastic soft pads, which are arranged at an angle. The plurality of soft pads are evenly arranged along the circumferential direction so that the lowest point of the previous soft pad is located below the highest point of the next soft pad to form a spiral structure.

[0033] Continue to refer to Figures 1 to 5 When the present invention is used, the bottom tube 3 is first set on the biopsy port 2, and then the splash-proof head 4 is set on the bottom tube 3 through a threaded connection. The splash-proof head 4 is rotated to drop the splash-proof head 4 to a sealing position. The blocking portion 43 passes through the tightening section 31 and is tightened by the tightening section 31 to form a sealed state, so that the middle hole 42 of the splash-proof head 4 and the active cavity 30 of the bottom tube 3 are not connected. When the biopsy port 2 is not in use, the blocking head 5 is set on the splash-proof head 4 to further enhance the sealing performance of the splash-proof head 4 and prevent the patient's body fluid from leaking.

[0034] When it is necessary to insert a medical device into the biopsy port 2, unplug the sealing head 5, rotate the splash head 4 to make the splash head 4 rise, and the blocking part 43 gradually expands as the splash head 4 rises. The expansion size of the blocking part 43 can be controlled according to the medical device that needs to be inserted. During the adjustment process, since a first splash plate 44 and a second splash plate 45 are provided above the blocking part 43, the patient's body fluid can be prevented from leaking. After the adjustment is completed, the medical device is inserted from the middle hole 42. The medical device can push open the first splash plate 44 from the cross groove 442 of the first splash plate 44, and after passing through the first splash plate 44, continue to push open the spirally arranged second splash plate 45 and finally pass through the opening of the blocking part 43 and insert into the biopsy port 2. The first splash plate 441 and the second splash plate 451 are made of elastic material, which can be attached to the surface of the medical device when pushed open by the medical device, thereby preventing the leakage of body fluid.

[0035] The first and second splash guards 44, 45 are detachable. When worn, they can be removed and replaced separately, saving medical costs. The anti-slip strips 46 on the splash guard 4 prevent the operator's hands from slipping when rotating the splash guard 4, improving the accuracy and convenience of operation. The lifting handle 50 facilitates the removal and installation of the plugging head 5.

[0036] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
