Description
Technical Field
The utility model particularly relates to the technical field of medical equipment, particularly to a catheter guide sheath.
Background
Currently, in clinic, the catheterization of a patient is realized by inserting a urinary catheter into a bladder by a nurse or a doctor by using a disposable catheterization bag and then retaining the urinary catheter by injecting water into an air bag; however, when the urethra is narrow or obstructed, the urethral catheterization method is under blind vision, the urinary catheter can not pass through the narrow and is inserted into the bladder, and can fall off due to the resistance of the narrow peduncle, at the moment, a urethral bougie is generally adopted clinically to perform blind urethral dilatation, and then the urethral catheterization operation is continued; the blind vision mode can not only damage the urethra, but also cause urethral catheterization failure of a plurality of patients, and finally only can perform bladder puncture fistulization, thereby increasing the trauma and infection risk of the patients and increasing the difficulty of doctor-patient communication clinically; the ureter guide sheath is characterized in that the resectoscope is placed into the guide sheath, the urethra is inserted into the urinary bladder under direct vision, the ureter enters the urinary bladder and then exits from the inner sheath of the resectoscope and the speculum, the ureter is placed into the urinary bladder through the notch of the outer sheath in the indwelling urinary tract, the urinary bladder is filled with the air bag, and the slotted outer sheath is then exited, so that the ureter is smoothly indwelling in the urinary bladder urethra, and the catheterization is completed.
The traditional catheterization has the advantages of flexibility, controllability, simplicity, small injury and the like, and is still the most commonly adopted method in the current clinical catheterization; however, these techniques have some problems as follows; firstly, for patients with urinary tract stenosis and urinary tract obstruction, the success rate is greatly reduced; second, it is very much related to the experience and skill of the operator; third, urinary catheterization is often repeated with multiple attempts or urethral dilations, increasing the risk of urethral injury; fourth, when the above procedure still fails to place the ureter successfully, the bladder puncture fistulization is often performed, which brings surgical risks to the patient.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides a urinary catheter guide sheath to solve the problems in the background technology.
In order to achieve the above object, the utility model provides a following technical scheme: a urinary catheter introducer sheath, comprising:
the left side wall and the right side wall of the connecting valve are respectively provided with a water outlet and a water inlet;
the water injection valve is hermetically communicated with a water inlet of the connecting valve by adopting a water injection pipe;
the water outlet valve is in sealed communication with the water outlet of the connecting valve;
the bottom end of the guiding catheter sheath is hermetically arranged at the top port of the connecting valve, and a guiding catheter groove is formed in the side wall of the guiding catheter sheath.
Further, preferably, a notch having an inclination angle of 45 ° is provided at the tip of the urinary catheter sheath, and the notch is located at the tip of the urinary catheter guiding groove.
Further, it is preferable that the length of the urinary catheter sheath is set to 180mm, and the outer diameter thereof is set to 9 mm.
Further, preferably, the width of the catheter groove is set to 4.5 mm.
Further, preferably, the bottom end of the urinary catheter guiding groove is provided with a semicircular notch.
The utility model adopts the above technique, compare with current technique and have following beneficial effect: the utility model discloses the device can be simple, convenient, swift keeps somewhere the ureter, reduces and leads urine because of the urethra is narrow or block a lot of that brings repeatedly, reduces the unnecessary damage to do not need the operator to have abundant experience, like this, in clinical operation, not only can be comprehensive, timely keep somewhere the ureter, can also reduce medical staff's work load, improve work efficiency and patient comfort level.
Drawings

Detailed Description
With reference to the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below.
Example (b): referring to fig. 1-3, the present invention provides a technical solution: a urinary catheter introducer sheath, comprising:
a water outlet and a water inlet are respectively arranged on the left side wall and the right side wall of the connecting valve 5;
the water injection valve 1 is hermetically communicated with a water inlet of the connecting valve 5 by a water injection pipe 6;
the water outlet valve 2 is hermetically communicated with the water outlet of the connecting valve 5;
the bottom end of the guiding catheter sheath 4 is hermetically arranged at the top port of the connecting valve 5, and a guiding catheter groove 3 is formed in the side wall of the guiding catheter sheath 4.
In this embodiment, the top end of the guiding catheter sheath 4 is provided with a notch with an inclination angle of 45 °, and the notch is located at the top end of the guiding catheter groove 3.
In this embodiment, the length of the urinary sheath 4 is set to 180mm, and the outer diameter thereof is set to 9 mm.
In this embodiment, the width of the urethral canal guide 3 is set to 4.5 mm.
