Description
Technical Field
The utility model relates to the technical field of urethral catheterization devices, in particular to a urethral catheterization device with a bladder perfusion function.
Background
A catheter is often required to be placed in front of the gynecological operation to keep the bladder in an empty state, so as to avoid damage to the bladder during the operation. However, in some special cases, it is desirable to fill the bladder with a color reagent (e.g., a methylene blue diluent) to determine the location and integrity of the bladder.
The method adopted at present is to prick the catheter tube wall by the needle of the infusion set and then infuse the physiological saline dissolved with methylene blue into the bladder by using the mode of pressurized infusion. However, the needle is not easy to be fixed with the catheter wall, so that the needle is possibly displaced, and the color developing agent flows outwards, thereby affecting the operation process.

The utility model aims to solve the problems and provide a urethral catheterization device with a bladder perfusion function.
The technical aim of the utility model is realized by the following technical scheme: the utility model provides a urethral catheterization device that has bladder filling function, includes catheter and three-way valve, catheter one end is equipped with the fluid-discharge tube, the fluid-discharge tube can dismantle with the three-way valve and be connected, catheter keeps away from fluid-discharge tube one end and is equipped with the catheter head, catheter head bottom side is equipped with the pneumatic valve, catheter one side is equipped with the soft valve.
The utility model is further provided with: the three-way valve comprises a valve, a first channel, a second channel and a third channel, and the first channel is connected with the liquid discharge pipe.
The utility model is further provided with: the catheter main body is made of sterilized silica gel, and the three-way valve is made of ABS or PP.
In summary, the utility model has the following beneficial effects:
the utility model relates to a urethral catheterization device with a bladder perfusion function, which adopts a double-cavity catheter, and a three-way valve is additionally arranged at the tail end of the double-cavity catheter, so that the bladder perfusion function is increased, the phenomenon of outflow of liquid possibly occurring when an infusion apparatus is used for perfusion is avoided, and the bladder perfusion efficiency is improved.

In the figure: 1. a urinary catheter; 101. an air bag; 102. a urine tube head; 103. a liquid discharge pipe; 104. a soft valve; 2. a three-way valve; 201. a first channel; 202. a second channel; 203. a third channel; 204. and (3) a valve.
Detailed Description
In order that those skilled in the art will better understand the present utility model, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings, wherein it is to be understood that the illustrated embodiments are merely exemplary of some, but not all, of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The present utility model will be described in detail with reference to examples.
Examples:
as shown in figure 1, the urethral catheterization device with the bladder perfusion function comprises a catheter 1 and a three-way valve 2, wherein a liquid discharge pipe 103 is fixedly arranged at one end of the catheter 1, the liquid discharge pipe 103 is detachably connected with the three-way valve 2, a catheter head 102 is fixedly arranged at one end, far away from the liquid discharge pipe 103, of the catheter 1, an air valve is fixedly arranged at the bottom side of the catheter head 102, and a soft valve 104 is fixedly arranged at one side of the catheter 1.
In this embodiment, the catheter 1 is made of sterilized silica gel, and is a dual-lumen catheter with a total length of about 40cm. At one end is a urine head 102 and an air bag 101, and at the other end is a soft valve 104 and a liquid discharge tube 103. The soft valve 104 is communicated with the air sac 101 through the outer cavity of the catheter 1, the soft valve can be used for fixing the catheter 1 after the physiological saline is injected, when the long axis of the three-way valve 2 is perpendicular to the long axis of the catheter 1, the first channel 201 is closed, the second channel 202 and the third channel 203 are opened, and when the long axis of the three-way valve 2 is parallel to the long axis of the catheter 1, the third channel 203 is closed, and the first channel 201 and the second channel 202 are opened.
The three-way valve 2 comprises a valve 204, a first channel 201, a second channel 202 and a third channel 203, wherein the first channel 201 is connected with the liquid discharge pipe 103.
In this embodiment, the three-way valve 2, the first channel 201 is connected to the drain 103, the second channel 202 is connected to the drain bag, the third channel 203 is connected to the syringe (for infusion),
the main body of the catheter 1 is made of sterilized silica gel, and the three-way valve 2 is made of ABS or PP.
Working principle: after the catheter 1 is placed, the soft valve 104 is filled with 10ml of physiological saline to fill the balloon 101, and the catheter 1 is fixed. And the second 202 port of the passage of the three-way valve 2 is connected with a drainage bag. When bladder emptying is desired, valve 204 is rotated so that the long axis of three-way valve 2 is parallel to the long axis of the urinary catheter. When bladder perfusion is desired, valve 204 is again rotated so that the long axis of three-way valve 2 is perpendicular to the long axis of the catheter. And the port three 203 of the channel is connected with a 50ml syringe, so that the liquid in the syringe can be injected into the bladder.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
