Description

Bladder irrigation converter

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a converter is washed to bladder.

Background

Bladder cancer is the most common malignant tumor of the urinary system and is better developed in middle-aged and old men. Benign prostatic hyperplasia is one of the best diseases for elderly men. Currently transurethral prostatectomy is one of the more widely used surgical approaches in the clinic. At present, transurethral prostate electrosectomy is one of more extensive operation modes clinically adopted, and patients after the electrosectomy usually need to keep a three-cavity catheter for bladder irrigation and press the wound surface of the prostate to stop bleeding after the operation. Although the resected prostate tissue is flushed after the resectoscope, partial tissue or blood clots are inevitably left, so that the catheter is blocked when the patient returns to the affected area for bladder flushing, and great pain is brought to the patient. Clinically, no simple treatment method exists for the phenomenon, and a syringe is often needed to pump physiological saline and connect a catheter for rapid bladder irrigation so as to pump out blood clots and dredge the catheter.

However, the caliber of the injection end of the existing syringe is not matched with the diameter of the port of the urinary catheter, an operator needs to firmly pinch the joint of the urinary catheter and the syringe by hand when using the syringe, and then pushes the liquid medicine, but the method causes inconvenient operation of the operator, and simultaneously, the caliber of the injection end is not matched with the diameter of the port of the urinary catheter, so that the hole is still large although the operator manually pushes the syringe, in the process of pushing the liquid medicine, the liquid medicine may flow out, the hand of the operator is dirtied, the liquid medicine is wasted, the pushing and metering are inaccurate, and the treatment effect is affected.

Detailed Description

The present invention will be further explained below.

Example (b):

as shown in fig. 1, the bladder irrigation transducer comprises an outer shell 1 and an inner core 2, wherein the inner core 2 is arranged in a circular truncated cone shape and is made of latex. The outer shell 1 is arranged in a tubular shape and sleeved outside the inner core 2, and the outer shell 1 is made of hard plastic so as to reduce interference of connection of the outer shell 1 and the ureter on liquid medicine delivery.

The central axis of the inner core 2 is provided with a transfusion channel 21 in a penetrating way, the larger end of the inner core 2 is provided with a funnel-shaped guide groove 22, and the guide groove 22 and the transfusion channel 21 are coaxial and communicated.

The larger end of the guide groove 22 is larger than the caliber of the injection end of the injector, the diameter of the transfusion channel 21 is smaller than the caliber of the injection end of the injector, the depth of the guide groove 22 is smaller than the length of the injection end of the injector, the inner core 2 is made of latex, and the injector is selected from a common 10ml injector as a standard in the embodiment. The guide groove 22 is firstly used for guiding so as to facilitate the insertion of the head of the syringe, and secondly, when the head specification of the syringe is large, the inner core 2 is made of latex, so that the deformation capacity is large, the head of the syringe can be clamped in the guide groove 22 and is fixed in the guide groove 22, and the adaptability to syringes of different specifications is achieved. The depth of the guide groove 22 is smaller than the length of the injection end of the syringe so that the head of the normal-sized and smaller-sized syringes can be inserted into the administration channel 21 to be fixed in the administration channel 21.

The lateral wall of infusion passageway 21 has seted up round recess 23, and this recess 23 sets up in the junction of infusion passageway 21 and guide way 22, and the head that the syringe was convenient for to the setting of recess 23 inserts infusion passageway 21, and when the head of syringe was inserted, the round ring piece that forms because of recess 23 took place to deform simultaneously, is the latex material because of inner core 2, and the cover that this ring piece can be firmly can effectually prevent the leakage of liquid medicine at the head of syringe.

Round auxiliary groove 24 has been seted up to the lateral wall of inner core 2, auxiliary groove 24 cut personally submits the arc setting, auxiliary groove 24 is located the junction of guide way 22 and infusion passageway 21, auxiliary groove 24's setting can be convenient for the deformation of inner core 2, reduce the interference that shell 1 caused inner core 2 deformation, the inner core 2 reconversion of can being convenient for of setting up of arc groove reduces the production of here stress, reduces the damage of inner core 2.

The outer diameter of the smaller end of the shell 1 is smaller than the diameter of the ureteral orifice, and the outer diameter of the larger end of the shell 1 is larger than the diameter of the ureteral orifice. Since the diameter of the ureteral orifice is between 6mm and 8mm, the larger end diameter is 12mm in this embodiment to ensure that the transducer does not enter the ureter in its entirety. This design allows the smaller end of the housing 1 to be easily inserted into the orifice of the ureter without the larger end entering the ureter orifice. Since the ureter is mostly made of natural rubber, the shell is fixed at the position of the ureter orifice under the self elasticity of the ureter, and the overall taper of the converter is about 2:15 for facilitating the connection between the shell 1 and the ureter.

When the converter is dismounted, in order to avoid the situation that the converter is not easy to pull out under the action of atmospheric pressure due to the excessive attachment between the shell 1 and the ureter, the outer side wall of the shell 1 is provided with a constant pressure groove 11, and two ends of the constant pressure groove 11 are respectively positioned at the larger end of the shell 1 and the smaller end of the shell 1, so that the converter is convenient to dismount. For the convenience of applying force by an operator, the shifting piece 3 is arranged on the outer side wall of the end part of the larger end of the shell 1, and the operator can hold the shifting piece 3 to pull outwards, so that the converter can be detached from the urinary catheter.

The operation process is as follows:

the operating personnel inserts the less end of shell 1 into the ureter mouth of pipe at first to make this converter fix the tip at the ureter under the elastic effect of ureter self, operating personnel holds between the fingers shell 1 afterwards, inserts the head (being injection end) of syringe into guide way 22, and make the head of syringe fix under the elastic effect of inner core 2 self, and operating personnel can inject the liquid medicine in the syringe into the converter this moment, and liquid medicine popular infusion passageway 21 gets into in the catheter. The converter is convenient for an operator to connect the syringe with the ureter, thereby facilitating the use of the operator and simultaneously reducing the leakage phenomenon of the liquid medicine from the joint of the syringe and the ureter. The converter has simple structure, low cost and easy production, and can be made into disposable products, thereby ensuring the sanitary condition of the converter.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
