Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following.

Example 1:

as shown in fig. 1 to 8, a urinary leakage prevention indwelling catheter device comprises a locking and positioning component which is used for being sleeved outside a catheter and has the function of sliding and locking along the length direction of the catheter.

Further, locking locating component includes connecting piece 2, clamping piece 3, retaining member 4 and can the butt at urethral export's bolster 1, and bolster 1 is scalable, realizes soft keeping out with urethral export, bolster 1 is connected with detachable mode (for example, joint is connected, threaded connection) the one end of connecting piece 2, bolster 1 includes along its axial be provided with through-hole 1d, integrated into one piece's buffering portion 1b and the gentle drift. Connect in connecting piece one end with the detachable mode through the bolster, and the bolster includes the modular design who is provided with through-hole, integrated into one piece's buffering portion and slow drift along its axial, has realized changing suitable, the bolster of different grade type according to the actual conditions of the urethral export of different use crowds, enlarges the scope of using the crowds.

Further, the buffering part 1b is provided with a corrugated tubular structure with at least one wave crest, and the corrugated tubular structure has certain telescopic capacity, so that the fitting surface 1a and the urethral outlet are more tightly fitted. The buffer head is kept away from a terminal surface of connecting piece 2 and is binding face 1a, binding face 1a is the conical surface structure, binding face 1 a's tip and buffer 1 b's one end integrated into one piece, buffer 1 b's the other end is equipped with joint portion 1c with integrated into one piece's mode, joint portion 1c joint is on connecting piece 2. Under the buffering effect of the buffering part 1b, the binding surface 1a forms a pretightening force for the urethral outlet, and the soft resisting effect is realized.

Further, an annular groove is formed in the side wall of the clamping portion 1c, a clamping step 2a extending inwards is arranged at one end of the connecting piece 2, and the clamping step 2a is clamped in the annular groove.

Further, the connecting piece 2 is a hollow structure, the clamping piece 3 is coaxially arranged inside the connecting piece 2, the clamping piece 3 comprises a cylindrical surface section 3a and a conical surface section 3b, the small end of the conical surface section 3b is connected with the cylindrical surface section 3a, the diameter of the small end of the conical surface section 3b is the same as the outer diameter of the cylindrical surface section 3a, under the extrusion state without external force, a gap is arranged between the clamping hole 3e and the catheter 5, a plurality of contraction joints 3c are arranged on the side wall of the clamping part 3, the outer diameter of the cylindrical surface section 3a is smaller than the inner diameter of the connecting piece 2, the middle part of the conical surface section 3b is abutted against the inner edge of the end part of the connecting piece 2, retaining member 4 with connecting piece 2 is connected through screw-thread fit, the one end that connecting piece 2 was kept away from to retaining member 4 is provided with clamp ring 4a, clamp ring 4a butt is on the main aspects terminal surface of conical surface section 3 b. As shown in fig. 9, when in use, the locking member 4 is unscrewed, the urinary catheter 5 sequentially passes through the locking member 4, the clamping member 3, the connecting member 2 and the buffer member 1 of the device, the front end of the urinary catheter 5 is inserted into the bladder from the male urethra, the air bag at the front end of the urinary catheter 5 is inflated through the inflation port, so that the air bag is attached to the inner wall of the bladder, at this time, the urinary catheter 5 cannot be pulled out, but can move inwards, in this state, the buffer member 1 of the device is abutted to the outlet of the urethra, the locking member 4 is screwed, the clamping ring 4a pushes the clamping member 3 to move towards one side of the buffer member 1 along the axial direction of the connecting member 2, the conical surface section 3b is abutted to the inner edge of the end portion of the connecting member 2, so that the gap of the contraction joint 3c is gradually reduced, namely, the gap between the clamping hole 3e and the urinary catheter 5 is also gradually reduced, and finally, the clamping hole 3e is clamped and fixed with the urinary catheter 5, a fixed distance is determined by the device and the air bag together, so that the position of the catheter 5 in the urethra is fixed, and the catheter 5 with different lengths of the urethra is fixed by adjusting the position of the device. Wherein, the buffer member 1 is made of a material having an elastic function.

Further, the contraction joint 3c extends from the large end face of the conical section 3b to the middle of the cylindrical section 3 a.

Furthermore, the big end face of the conical surface section 3b is also provided with a pressing step face 3d, and the pressing ring 4a is pressed on the pressing step face 3 d. The matching of the pressing step surface 3d and the pressing ring 4a prevents the deviation of the axis of the clamping piece 3, and meanwhile, the automatic centering effect is also achieved between the conical surface section 3b and the inner edge of the end part of the connecting piece 2, so that the clamping piece 3 and the connecting piece 2 are ensured to be always in a coaxial state.

Further, the buffer member 1 is made of a flexible material. For example, silicone rubber, is softer in texture, improving patient comfort.

Further, the middle part of connecting piece 2 is equipped with spacing ring 2b to spacing ring 2b is the border, connecting piece 2 is provided with anti-skidding line on being close to the one end lateral wall of bolster 1, and the one end that is close to retaining member 4 is provided with the external screw thread that can with retaining member 4 spiro union, be provided with anti-skidding line on retaining member 4's the lateral wall. The setting of spacing ring 2b can make the locking position of retaining member 4 carry on spacingly, prevents that retaining member 4 locking volume is too big, leads to catheter 5 to receive the extrusion too big, and the unhooked condition of catheterization appears. And the antiskid line can prevent to skid when screwing, improves operating efficiency.

Example 2:

example 2 is the same as example 1 in other structures except that: locking locating component includes connecting piece, clamping piece, retaining member and can the butt at the bolster of urethra export, the bolster is connected with the detachable mode the one end of connecting piece, the bolster includes that its axial is provided with the elastic component and the gentle drift that the through-hole, but split connection are followed. By the combined design of the buffer member comprising the detachably connected elastic member (e.g. spring) and the buffering head (e.g. silicone head) which are provided with the through holes along the axial direction thereof, buffering of the urethral outlet of different users can still be realized.
