Description
Technical Field
The utility model belongs to the field of medical equipment, especially, relate to a novel catheter.
Background
As a clinical common medical instrument, the urinary catheter is placed into a human body through the urethra and then drains urine from the bladder to the outside of the body, has the main functions of accurately recording urine volume, facilitating drainage, flushing and the like, and plays an important role in clinic.
The catheter is mainly made of silica gel, rubber, EVA, PVC and the like, and the head end and the catheter body are soft. But the resistance in the urethra of some patients is larger due to the conditions of urethral stricture, prostatic hyperplasia, canceration, bladder neck sclerosis and the like, thereby greatly increasing the difficulty of catheterization. The existing clinical catheterization is usually to fix the external urethral orifice with one hand after disinfecting the external urethral orifice and surrounding tissues, and the other hand directly holds the urethral catheter or holds the urethral catheter with forceps and the like, and the urethral catheter is inserted from the urethral orifice, and needs to be put in harder when facing the situations of resistance bending and stenosis, which brings great pain to patients, causes the damage of urethral mucosa, causes the damage of urinary tract structure, and increases the risk of urethral infection.
The existing clinical catheter implanting process has the following problems: when the top end of the head of the catheter advances to the narrow part of the urethra, external force is required to be increased for propulsion, the top end of the head and the urethra at the narrow part can generate a shearing effect, even if the head passes through the narrow urethra, the inner membrane of the urethra is seriously contused and conditions are created for microbial infection, lubricating oil and the like are smeared on the outer surface of the catheter, and the effect is very little when the urethral stricture is met.
It is sometimes very difficult to place a urinary catheter and replace a urinary catheter clinically, and it is easy to cause secondary urethral damage caused by violence when inserting the urinary catheter, such as false tract, bleeding, perforation, etc., and further aggravate the severity of urethral disease, influence the healing of urethra, even cause complicated urethral damage and stenosis, and seriously affect the quality of life of patients. Therefore, for the patients, in order to avoid false passage when the catheter is placed, the catheter is often placed under the guidance of a guide wire. Most of the existing catheters are tube bodies with the front ends sealed and the rear ends opened, and the side openings are communicated with the catheter cavity. When the catheter is placed into the guide wire, the guide wire is led out from the side opening of the catheter through the lumen, so that the catheter and the guide wire cannot be parallel to each other, the guide is difficult, and the catheter is not placed into the catheter.
Disclosure of Invention
The utility model aims at providing a simple structure, imbed convenient operation's a novel catheter of taking narrow expansion seal wire.
The technical scheme of the utility model is that:
the utility model provides a novel catheter, including pipe and seal wire, be equipped with inflation channel in the pipe, wash passageway and urine passageway, be equipped with the urine entry on the front end lateral wall of urine passageway, the rear end of pipe is equipped with the urine chamber, be equipped with respectively on the lateral wall in urine chamber with wash the chamber of washing that the passageway is linked together and with the inflation chamber that inflation channel is linked together, the seal wire sets up inside the urine passageway, the seal wire is the tubulose, the internal diameter of urine passageway is greater than the external diameter of seal wire, the front end of seal wire is equipped with the outside seal wire gasbag that is located the catheter front end, the rear end of seal wire is equipped with connecting portion, the rear end of connecting portion is equipped with the elasticity utricule, connecting portion are connected with the urine chamber, the elasticity utr.
Extrude elasticity utricule during the use, during air or liquid enter into the seal wire gasbag, strut the narrow department of urethra, loosen elasticity utricule, the catheter impels forward, operates repeatedly, and the catheter is implanted easily, and can not cause the injury to the urethra when implanting the operation, and the security is high.
The diameter of the guide wire balloon after filling is larger than the outer diameter of the catheter and smaller than the outer diameter of the catheter balloon when filling.
The elastic bag body is detachably provided with a sealing plug.
The sealing plug on the elastic bag body can be detached, and gas or liquid is supplemented into the elastic bag body.
The outer side wall of the connecting part is in interference fit with the inner side wall of the rear end of the urine cavity.
The outer side wall of the front end of the connecting part is provided with an annular guide wire groove, and the inner side wall of the rear end of the urine cavity is provided with a bulge matched with the guide wire groove.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the catheter is implanted more safely and conveniently; has the advantages of simple structure, low processing cost, high safety and the like.
