Detailed Description

The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.

Referring to fig. 1-5, the anti-fouling auxiliary device for endoscopy in this embodiment includes a main body 1, the main body 1 is a hollow cylindrical structure with openings at the upper and lower ends, the upper end opening of the main body 1 is in fit and sealing fit with the surface of an endoscope 4, a spherical valve member 2 is arranged at the upper end opening of the main body 1, the valve member 2 includes a plurality of valves 21 which are circumferentially and equidistantly arranged, the edge fit of the adjacent valves 21 forms a closed port, the lower end opening of the main body 1 is in fit and sealing fit with the outer surface of an outer sleeve catheter 5, an annular buckle 3 protruding inwards is arranged in the lower end opening of the main body 1, and the main body 1, the valve member 2 and the annular buckle 3 are all elastic.

When the utility model is used, firstly, the lower end opening of the main body 1 is expanded, so that the lower end opening of the main body 1 is sleeved to the inlet position of the outer sleeve pipe 5, the annular buckle 3 is matched with the convex circular ring 51 at the inlet position of the outer sleeve pipe 5 to play a role of clamping and fixing, the risk that the main body 1 falls off from the outer sleeve pipe 5 when being pulled is reduced, the main body 1 is tightly attached to the surface of the outer sleeve pipe 5 under the elastic action of the main body 1, then the endoscope 4 is inserted from the valve part 2 to separate the valve 21 from each other, the valve part 2 is expanded and is always attached to the surface of the endoscope 4 under the elastic action of the endoscope 2, and therefore, when sewage in the intestinal tract of a patient flows outwards along the outer sleeve pipe 5, the sewage can play a blocking role through the sealing attachment of the main body 1 and the outer sleeve pipe 5 and the endoscope 4, the risk that the sewage flows out along the outer sleeve pipe 5 to pollute an operation table top and an operation room is reduced, and meanwhile, the problems that medical staff needs to wear a plurality of layers of protection boots and increase the operation time and extend the anesthesia time are solved.

When the endoscope 4 is not inserted, the adjacent valves 21 can keep the edge fitting state, so the valve piece 2 forms a closed mouth, and the endoscope 4 can also play a role of sealing to reduce the risk of sewage outflow when not inserted.

Referring to fig. 1, 3-5, the main body 1 includes a fixing section 11 and a bending section 12, the fixing section 11 and the bending section 12 are in a hollow structure connected up and down, the internal cavities of the fixing section 11 and the bending section 12 are communicated, the fixing section 11 is adapted to be sealed and attached to the outer surface of the inlet position of the casing catheter 5, and the bending section 12 is adapted to be sealed and attached to the outer surface of the endoscope 4.

By increasing the bonding area between the bending section 12 and the surface of the endoscope 4 and thus improving the sealing effect, the bending section 12 bends inwards towards the outer sleeve 5 (as shown in fig. 4) during the process of inserting the endoscope 4 into the outer sleeve 5, and the bending section 12 bends outwards towards the outer sleeve 5 (as shown in fig. 5) during the process of extracting the endoscope 4 from the outer sleeve 5, so that the bending section 12 can always keep bonding with the surface of the endoscope 4 to play a sealing role, and meanwhile, the bending section 12 can be positioned between the endoscope 4 and the outer sleeve 5 to play a buffering role during the process of inserting the endoscope 4, thereby reducing the risk of damaging the surface of the endoscope 4 caused by direct contact friction between the endoscope 4 and the outer sleeve 5.

Referring to fig. 3-5, the annular clasp 3 is provided with two, including an upper annular clasp 31 near the middle of the fixed section 11 and a lower annular clasp 32 near the lower end opening of the fixed section 11.

When the fixing section 11 is sleeved on the outer sleeve pipe 5, the upper annular buckle 31 is matched with the convex circular ring 51 at the inlet position of the outer sleeve pipe 5 to play a role in clamping and fixing, the upper annular buckle 31 and the lower annular buckle 32 enable the fixing section 11 to be attached to the outer surface of the outer sleeve pipe 5, the attaching area of the fixing section 11 and the outer sleeve pipe 5 is increased, when the main body 1 is pulled by large external force to cause the upper annular buckle 31 to be separated from the outer sleeve pipe 5 and even fall off from the outer sleeve pipe 5, the sealing and clamping and fixing functions can be played through the lower annular buckle 32, and the risk that the main body 1 falls off directly from the outer sleeve pipe 5 is reduced, so that the anti-leakage effect of the utility model is improved, and the stability in use of the utility model is improved.

Referring to fig. 3, the left and right ends of the upper annular buckle 31 are fixed to the inner wall of the fixed section 11, and the rest of the upper annular buckle 31 is separated from the inner wall of the fixed section 11.

During installation, the lower annular buckle 32 is turned upwards from the outer side to expose the upper annular buckle 31, fingers or other tools (such as tweezers) are used for being respectively inserted into gaps between the front side and the rear side of the upper annular buckle 31 and the inner wall of the fixed section 11, the upper annular buckle 31 is pulled outwards to expand and sleeved on the lower side of the convex circular ring 51 of the outer sleeve guide pipe 5 to realize clamping and fixing, and finally the lower annular buckle 32 is pushed downwards to enable the lower annular buckle 32 to move to the lower side of the upper annular buckle 31 and finally the fixed section 11 to be unfolded and restored, so that the installation of the utility model is realized.

The main body 1, the valve piece 2 and the annular buckle 3 are integrally formed by silica gel.

The silica gel has the advantage of good flexibility, can repeatedly turn over the bending section 12 and be attached to the surface of the endoscope 4 in the repeated inserting and extracting process of the endoscope 4, reduces abrasion caused to the surface of the endoscope 4, and is low in material cost, so that the utility model can reduce operation cost when being used as disposable consumable, and does not increase the economic burden of a patient.

In mass production, the main body 1, the valve piece 2 and the annular buckle 3 are integrally formed through the die, then the valve 21-shaped opening is formed at the upper end closed position of the bending section 12 through cutting, and finally the upper annular buckle 31 is exposed outside by turning the fixing section 11 to partially cut the upper annular buckle 31 and separate from the inner wall of the fixing section 11.

The foregoing description of the utility model is merely exemplary of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the utility model as defined in the accompanying claims.
