Detailed Description

With reference to fig. 1 to 5, the features of the anal dilator are detailed as follows:

the utility model provides an anal dilator, is including stretching into the expansion tube 100 in patient's anus, expansion tube 100 wholly is straight tube column structure, expansion tube 100 one end is big, the one end is little to be arranged, the anus of patient is stretched into to the small-size end of expansion tube 100, the big chi end of expansion tube 100 stretches out patient's anus and is connected with fixed knot structure, fixed knot structure is connected with patient's belly or shank.

When the patient adopts the anal dilator to perform colonoscopy, the anus of the patient is led into the dilating tube 100, the dilating tube 100 is fixed on the abdomen or the leg of the patient through the fixing structure, so that the dilating tube 100 is fixed, during detection, the colonoscope enters the anus of the patient through the dilating tube 100, and then the contact between the colonoscope and the anus periphery of the patient can be avoided, so that the comfort level of the colonoscopy during detection can be improved.

The expansion pipe 100 is large in one end and small in one end, the expansion pipe 100 can be conveniently stretched into the anus of a patient, and therefore the auxiliary tool is convenient to use, the expansion pipe 100 is made of hard silica gel materials, and the comfort degree of the anus of the patient and the expansion pipe 100 is improved.

In order to ensure the normal use of the dilator and avoid the situation that the dilating tube 100 is guided into the anus and cannot be drawn out, the large-size end of the dilating tube 100 is provided with an abutting sheet 200, and the abutting sheet 200 is attached to the hip position of a patient.

The paste piece 200 is made by flexible silica gel material, and after the extension tube 100 stretched into the anus, the paste piece 200 is attached at the buttock position of the two sides of the femoral groove of the patient, and the expander can be conveniently fixed through the implementation of a fixing structure.

Specifically, the whole of the sheet 200 is in the shape of an arc plate, and the fixing structure includes a fixing bandage 300 disposed on the sheet 200, and the fixing bandage 300 is connected to the abdomen or the leg of the patient.

The fixing bandage 300 is fixed in the both ends position of pasting the piece 200, and back in the anus that stretches into the patient when the expansion pipe 100 for paste the piece 200 and paste in patient's buttock position, make fixing bandage 300 around establishing at patient's thigh position, perhaps patient's belly position, and then realize the fixed of this expander, avoid expansion pipe 100 to take out from patient's anus at will.

Preferably, in order to facilitate the insertion of the colonoscope into the dilation tube 100, the abutment plate 200 is provided with a through hole 210, and the through hole 210 is communicated with the large-sized end nozzle of the dilation tube 100.

Specifically, in order to avoid random gas or foreign matter discharge from the anus, especially for patients with anal fistula, a flap 110 is disposed in the small-sized end orifice of the dilation tube 100, the flap 110 and the inner wall of the dilation tube 100 form a one-way conduction valve, and the one-way conduction direction formed by the flap 110 and the dilation tube 100 is directed from the large-sized end orifice to the small-sized end orifice.

During actual examination, the colonoscope is inserted through the large-sized end of the dilation tube 100, and the flap 110 is tightly attached to the outer wall of the colonoscope to prevent the anus from exhausting air or foreign objects at will.

Preferably, the flap sheets 110 are provided in plurality at intervals along the circumferential direction of the inner wall of the expanding tube 100.

More specifically, the edge of the through hole 210 is located at the arc transition of the sheet 200.
