Referring to fig. 1 to 2, the cleaning fixing block of the embodiment of the present invention is applied to the cleaning of the soft endoscope, and includes a block 100, a fixing portion 200, a bayonet 300 and a cleaning hole 400.

Wherein the block body 100 is non-toxic, wear-resistant and has a certain softness, and the fixing part 200, the bayonet part 300 and the cleaning hole 400 are all processed and formed on the block body 100. In some embodiments of the present invention, the block 100 is a rubber block, which is made of medical grade rubber with a thickness of about 5-8CM, a length of 2.5CM and a width of 2CM. Further, when the fixing portion 200 is a U-shaped bayonet, the radius is about 0.7mm, which is equivalent to half the diameter of the gas injection and water injection port of the soft endoscope operation portion, and the cleaning fixing block can be correctly used based on the installation position. When the bayonet part 300 is set as a sink, its diameter is about 1.4mm, which is the peripheral aperture of the suction inlet of the endoscope operation part. The size of the cleaning hole 400 is about 0.3mm, which is the diameter of the brush wire, and the brush is inserted along the notch 500 at a specific inclination angle when being brushed by the brush.

Wherein fixed part 200 sets up at block 100, fixed part 200 is used for fixing the preset position at soft scope, can understand, through fixed part 200 with block 100 fixed connection in soft scope, wherein fixed position need guarantee bayonet part 300 can be located suitable position, attract mouthful contactless when scrubbing with the scope in order to guarantee the brush, thereby make a round trip to extract, do not take place the friction when inserting, preferred fixed part 200 can also set up to the adhesive linkage, convenient structure of fixing at soft scope such as retaining member.

Wherein bayonet part 300 sets up and is used for inlaying the attraction hole periphery of establishing at soft scope at block 100 bayonet part 300, can understand that, when using earlier the bayonet part 300 cover establish on attracting the hole, then adjust orientation etc. of block 100 and fixed through fixed part 200 again to guarantee bayonet part 300's correct use, can fix the brush in the central authorities of attracting the hole when scrubbing.

Wherein cleaning hole 400 sets up at bayonet portion 300, and cleaning hole 400 runs through to the bottom of bayonet portion 300 from the top of bayonet portion 300, and cleaning hole 400 is the through-hole and forms in bayonet portion 300 for after bayonet portion 300 cover was established on the suction hole, the through cleaning hole 400 based on cleaning hole 400 can be used for guiding the brush and stretch into in the suction hole. When specifically using, fix the position in the preset of block 100 in soft scope as fixed end through fixed part 200, this preset position is selected based on the hole position of attracting of soft scope, make bayonet portion 300 can inlay and establish in attracting the hole periphery, bayonet portion 300 inlays and establishes back purge orifice 400 and can with attract the hole intercommunication, it washs in the hole to get into the attraction through purge orifice 400 guide brush, make the brush of scrubbing get into or withdraw from this process of attracting the hole and can reduce the stainless steel thread long steel wire of brush and attract the steel wall wear in hole, thereby it is not defective to keep attracting entry steel wall, guarantee its and attract the leakproofness between the button, guarantee the pressure of negative pressure attraction, maintain the doctor and attract the normal of function when operating the scope.

In some embodiments of the present invention, the fixing portion 200 is a U-shaped bayonet formed on a side wall of the block 100. It can be understood that, when soft scope operation portion gas injection, water filling port are located attracts the hole next door, through the length of guaranteeing to wash the fixed block for the bayonet part 300 on the washing fixed block is when being located the position of attracting the hole, and a lateral wall of wasing the fixed block can block soft scope operation portion gas injection, water filling port through U type bayonet socket, thereby fixes block 100 through the mode of joint, and operation simple to use, fixed effective.

Preferably, the different specifications of different brands can be different slightly, and the size of block 100 can be adjusted slightly according to brand and specification, but under the prerequisite that soft scope operation portion gas injection, water filling port are located the suction hole next door, the relative fixed part 200 setting of bayonet part 300, bayonet part 300 is located another relative lateral wall of block 100 to carry out the adjustment of size under the reasonable prerequisite of overall arrangement, reduce the cost of manufacture, improve the preparation efficiency.

In some embodiments of the present invention, the bayonet portion 300 is configured as a sinking groove, and the cleaning hole 400 is configured as a through hole at the bottom of the sinking groove, preferably, the sinking groove is configured as a cylinder shape for the adaptive suction hole. It can be understood that the suction hole is generally cylindrical, so that the bayonet part 300 is provided as a cylindrical sunken groove, and the sunken groove is used for accommodating the suction hole, so that the operation and use are simple, the fixation is effective, and the correct guide of the brush can be ensured. Therefore, preferably, the cleaning hole 400 and the sinking groove are coaxially arranged, so that the hairbrush is ensured to be fixed at the center of the suction hole, and the hairbrush is ensured not to be in contact with the suction port of the endoscope during brushing, so that friction is not generated during back-and-forth extraction and insertion.

In some embodiments of the present invention, one side of the cleaning hole 400 is provided with the notch portion 500, the notch portion 500 has a guide surface, the guide surface is inclined, the top end of the guide surface is formed at the bottom of the sink, and the bottom end of the guide surface is butted against the cleaning hole 400. Preferably, the guide surface is arranged inclined at 45 °. It can be understood that in order to further reduce the friction between the brush and the suction inlet, it is necessary to guide the angle of insertion of the brush into the cleaning hole 400, and the cut-away portion 500 having the guide surface can play a role of guidance and guidance to ensure the correct use of the brush, thereby making it possible to prevent the brush from contacting and rubbing the suction inlet as much as possible.

Referring to fig. 1 to 2, the utility model discloses the soft scope of second aspect embodiment, soft scope can be the alimentary canal scope, including gastroscope, intestines mirror, duodenoscope, supersound scope etc, soft scope includes the utility model discloses the washing fixed block of first aspect embodiment can protect soft scope suction port structure normal, reduces the friction of cleaning brush and suction entry, prevents that wearing and tearing or defect from appearing in the stainless steel wall of entrance, can also guarantee the normal service function of soft scope equipment, reduces the friction that suction port enters the mouth, keeps the leakproofness between entry and the suction button, guarantees the pressure of negative pressure suction, maintains the normal of doctor suction function when operating the scope.

The technical features of the embodiments described above can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
