Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a waterproof abortion suction tube. Background Art

[0002] The structures of visual abortion suction tubes currently on the market are basically the same. The front end is composed of a transparent cover, an image acquisition component, a flexible PCB, a base for fixing the image acquisition device, and a pipeline shared by the flexible PCB and the negative pressure channel. Specifically, a disposable visual abortion suction tube disclosed in Chinese patent announcement number "CN205031343U" includes a suction tube assembly, which includes a transparent cover, a fixing part and a circular double-lumen tube; a camera module is provided in the transparent cover, the front end of the transparent cover is hemispherical, and one end of the fixing part is sealed and combined with the opening end of the transparent cover.

[0003] In order to facilitate the routing of the camera module, a through-hole is opened on the tube body, and the connecting wire is led out from the through-hole and electrically connected to the circuit board. However, in actual production or use, if the transparent cover is debonded or a leak occurs inside the body, tissue fluid will enter the handle through the through-hole along the routing cavity during the suction process. If the tissue fluid contacts the circuit board, it is easy to cause short circuit damage to the circuit board, and in severe cases it will affect the safety of the operation. Based on this, in order to improve the sealing performance of the existing suction tube, we propose a waterproof abortion suction tube. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 An embodiment of the utility model discloses a waterproof abortion suction tube, which comprises a gripping portion 1, a tube body 2 and a circuit board 3 are fixed inside the gripping portion 1, and a lens module 4 is fixed at the end of the tube body 2;

[0023] The tube body 2 includes a suction cavity 21 and a wiring cavity 22. A through hole 23 connected to the wiring cavity 22 is provided on the outer side of the tube body 2. The connection line of the lens module 4 extends outward along the wiring cavity 22 through the through hole 23 and is electrically connected to the circuit board 3. Specifically, the lens module 4 described in this embodiment includes a CMOS module and a light source. The connection line is a flexible FPC board. The specific connection method and principle have been disclosed in the prior art and will not be described in detail here.

[0024] A sealing component 5 is disposed on the outer side of the tube body 2 , and the sealing component 5 is used to seal the through-hole 23 .

[0025] In some embodiments, the sealing assembly 5 of the present invention includes a fixing ring 51 fixed to the outside of the tube body 2 and an adjusting ring 52 rotatably connected to the outside of the tube body 2 , and a resistance ring 53 is provided at the end of the adjusting ring 52 .

[0026] On the basis of the above embodiment, the adjusting ring 52 is threadedly connected to the tube body 2, and a first sealing ring 54 is further provided on the end face of the abutment ring 53, that is, in this embodiment, the adjusting ring 52 is rotated. The displacement control through the rotation of its thread is used to drive the abutment ring 53 to move. When the abutment ring 53 moves toward one side of the fixing ring 51, the connecting line of the lens module 4 is clamped and fixed by the extrusion deformation force of the first sealing ring 54, and the through-hole 23 is sealed to prevent the tissue fluid from entering the interior of the gripping part 1 through the wiring cavity 22 and the through-hole 23 when the end of the tube body 2 is debonded, thereby affecting the normal operation of the circuit board 3.

[0027] Furthermore, in the present embodiment, a positioning column 56 is fixed on the end face of the fixing ring 51, and a plurality of positioning holes 55 are circumferentially distributed on the end face of the abutment ring 53. The positioning column 56 is plugged into the positioning hole 55 for positioning. During the initial sealing, the position of the abutment ring 53 is first adjusted by the adjusting ring 52. When the abutment ring 53 contacts the fixing ring 51, the positioning column 56 and the positioning hole 55 are kept relative and plugged. The design purpose of adopting this structure is to ensure that in the subsequent clamping and sealing process, the relative rotation of the abutment ring 53 can be avoided, so as to avoid the problem of distortion force on the connecting line of the lens module 4 and damage to the connecting line. That is, in the present embodiment, the positioning column 56 and the positioning hole 55 are used to realize the relative linear movement of the abutment ring 53 and the fixing ring 51, so as to ensure the stable clamping and sealing of the connecting line.

[0028] On the basis of the above-mentioned embodiment, a wire outlet notch 57 is provided on the end face of the fixing ring 51 in the present embodiment, and a sealing gasket 58 is arranged in the wire outlet notch 57. The wire outlet notch 57 is used to position the connecting wire in the initial state. It should be noted that in the initial state, when the connecting wire is placed in the wire outlet notch 57, the outer side of the connecting wire should protrude from the side of the fixing ring 51, so that when clamping and sealing, the first sealing ring 54 and the sealing gasket 58 can achieve sealing and fixing of the connecting wire through extrusion deformation.

[0029] It should be noted that in the present embodiment, the outer side of the adjustment ring 52 is provided with a stop ring protrusion 59, and the stop ring protrusion 59 is used to limit the contact ring 53. A second sealing ring 591 is also provided on the outer side of the stop ring protrusion 59, that is, when the adjustment ring 52 is rotated, the stop ring protrusion 59 contacts the above-mentioned contact ring 53 and moves until it contacts the fixed ring 51. When the contact ring 53 and the fixed ring 51 are in contact and subjected to force, the two are connected and sealed by the first sealing ring 54 and the sealing gasket 58, and the rear side is sealed with the stop ring protrusion 59 by the second sealing ring 591, so that the through-opening 23 is completely sealed to achieve a waterproof effect.

[0030] In addition, in this embodiment, the first sealing ring 54 and the second sealing ring 591 are both configured as rubber rings, and the sealing pad 58 is configured as a rubber pad.

[0031] In summary, the utility model optimizes the design of the tube body 2 of the existing suction tube, and adopts a sealing component 5 to seal the connecting line through-hole 23 of the lens module 4, so as to prevent tissue fluid from flowing into the interior of the gripping part 1 through the through-hole 23 when the connection of the lens module 4 is debonded or a leak occurs in the tube body 2, thereby avoiding the problem of short circuit or damage of the circuit board 3 due to moisture, so as to optimize the overall waterproof performance. The sealing component 5 is simple in design. During assembly, the connection circuit board 3 is still first led out along the through-hole 23. Thereafter, the clamping force generated by the fixing ring 51 and the resistance ring 53 by operating the adjusting ring 52 can complete the sealing of the through-hole 23 and the connecting line, thereby further improving the durability of the existing suction tube.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
