After the utility model is assembled, the front end of the catheter core protrudes from the front end of thecatheter sheath to prevent the urethra from being injured in the operation process. The positioning short column is inserted into the positioning hole to play the function of axial positioning. The utility model has the advantages of high insertion success ratio and strong applicability. The utility model can avoid the pain for patients caused by operation, and the labor intensity of the doctors and the medical cost can be largely reduced.

Description

Catheter insertion device

This practicality newly relates to a kind of catheter inserter, is particularly useful for patients such as prostate hyperplasia urine retention and injury of urethra.

When suffering from sufferer such as prostate hyperplasia urine retention, injury of urethra when human body, can not normal voiding because of the urethra distortion, the processing method for above-mentioned situation is catheter to be inserted patient's urethra help controlled micturition at present.But the patient serious for the urethra distortion or urethra ruptures fully inserts very difficulty of catheter.Current both at home and abroad to prostate hyperplasia urine retention placement catheter loser, all adopt the operation method drainage of urine of bladder stoma, the releasing urine retention.The employing punctio vesicae method that has, this is a kind of emergency measure.For fresh injury of urethra is to adopt surgical operation therapy methods such as urinary anastomosis, prostate tip fixation, cystostomy and urethral reunion operation to carry out early time treatment., all adopt bladder to cut and cleared up through can not removing person for the hematocyst piece with catheter flushing.Owing to adopt surgical operation to cause suffering to the patient, prolong healing time, increase doctor's labor intensity and medical expense.

The purpose of this utility model is to provide a kind of catheter inserter, makes patient avoid the hardship of operation, alleviates doctor's labor intensity simultaneously.

This utility model is achieved in that the catheter inserter is made of pipe sheath and tube core, and the profile of pipe sheath is similar to divulsor, and its smooth-shaped does not have corner angle, has a support in its back-end, and a locating hole is arranged on this support.Tube core is an elongate rod, and its front portion is a rods, and the tube core front end is a fairing surface, and the shape of this place and pipe sheath front end matches, and its rear end has a location short column.After pipe sheath and the tube core assembling, tube core is inserted in the pipe sheath, and the tube core front end protrudes in pipe sheath front end, with the common outer surface that constitutes a smooth garden profit of pipe sheath front end, to prevent damaging urethra in the operating process.In the locating hole on the location short column insertion support of tube core rear end, play axial location.

The using method of this catheter inserter is, earlier by the urethra that after the above-mentioned requirements assembling this catheter inserter is inserted the patient, from locating hole, take out the location short column then, again tube core is extracted out, the pipe sheath is stayed in patient's the urethra, and the take-off pipe sheath got final product after tailing edge pipe sheath was inserted patient's urethra depths with existing catheter.In the practical operation, will enter along the urethra rear side at anterior urethra, urethra will enter along the urethra antetheca in the back.The operator must be familiar with the anatomic construction of urethra, grasps apparatus and inserts main points, and action is soft, accurate.For back urethra fracture person fully, should use and point, and pin prostate lightly downwards in the anal guide, make urethra involutory, help the catheter inserter and pass through.The meatal stenosis person inserts after should expanding in advance again.To be coated with lubricated paralyzant before inserting, still have the urethral orifice person of bleeding after catheter is inserted, the hemostasis by compression of available T-shape band.

Advantage of the present utility model is: 1, insert the success rate height, once insert success rate and reach more than 95%.2, the suitability is strong, not only can substitute existing catheter and insert method, and the patient's catheter that goes for the existing inefficient injury of urethra of urethral catheterization method, prostate hyperplasia urine retention, the cleaning of hematocyst piece and prostate excision situation such as deviates from, thereby avoids the misery of performing the operation and bringing to the patient to greatest extent.3, can alleviate doctor's labor intensity significantly.4, can reduce medical expense effectively.

Below in conjunction with drawings and Examples this utility model is further described.

The A-A broken section enlarged drawing of Fig. 4: Fig. 3.

Embodiment: the described catheter inserter of present embodiment is to be made of pipe sheath 1 and tube core 3.As shown in Figure 1, the profile of wherein managing sheath 1 is similar to divulsor, and its smooth-shaped does not have corner angle, and the sheath wall of front end is thinner, and the rear end of pipe sheath has a support 4, and a locating hole 5 is arranged on this support 4.As shown in Figure 2, tube core 3 is an elongate rod, and its front portion is flexible thin bar, can bending with the pipe shape of sheath, tube core 3 front ends have a slick spheroid 2, and this spheroid 2 matches with the internal diameter of managing sheath 1 front end place, the rear portion of tube core is a rigid rod, has a location short column 6 in its back-end.After pipe sheath 1 was assembled with tube core 3, as shown in Figure 3, tube core 3 was inserted in the pipe sheath 1, and the spheroid 2 of tube core 3 front ends protrudes in manages sheath 1 front end, and this spheroid 2 constitutes the outer surface that moisten in a smooth garden jointly with the front end of pipe sheath 1, to prevent damaging urethra in operating process.In the locating hole 5 that the location short column 6 of tube core 3 rear ends inserts on the support 4, play axial location, referring to Fig. 4.
