Abstract
The utility model provides an automatic pressure-inductive retainment urethral catheterization device, which is characterized in that a valve is additionally arranged on a pipe for urethral catheterization which is connected with a urine bag, the inner cavity of the valve is provided with a flap which causes the pipe for urethral catheterization to be blocked or communicated, or a pressure relay and an electromagnetic valve are additionally arranged on the pipe for urethral catheterization, and the output end of the pressure relay and the control end of the electromagnetic valve are connected with a time relay and an electric source. The utility model solves the side effect of bladder contracture which is generated by the original pipe for urethral catheterization, the utility model not only can maintain the normal function of a bladder but also can cause the storage time of urine to be shortened and reduce bacteria breeding and retroinfection. In addition, the utility model also has the advantages of simple structure and easy fabrication.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used for clinical to patient's urethral catheterization, especially a kind of automatic pressure induction indwelling catheter device.
Background technology
Indwelling catheter continues the common operation that urethral catheterization is clinical each section's extensive use to patient, and it is applicable to the high paraplegia patient, the bladder stoma patient, and coma patient, before the art, in the art, postoperative patient, and all need remember the patient of discrepancy amount.At present common indwelling catheter mainly is made up of with the urinal that is connected with the catheter lower end the catheter that inserts urethra, the catheter of this structure is continuously derived intravesical urine, the side effect of contracture of bladder can take place in this catheter of life-time service, in addition the urinal storage of urine time of this catheter oversize, bacteria breed easily takes place cause retrograde infection.
Summary of the invention
This utility model provides a kind of side effect little for solving the technical problem that exists in the known technology, the automatic pressure induction indwelling catheter device that the storage of urine time is short.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
A kind of automatic pressure induction indwelling catheter device is only pressed from both sides by catheter, the urinal that is connected with catheter and the water that is installed in the catheter lower end and to form, but the control device that conducting also is installed and closes on the described catheter.
This utility model can also adopt following technical measures:
Described control device is a valve, and circular cylindrical cavity is arranged in the valve body, and the center that is equipped with in the cavity is shaped on the flap valve of the frustum projection that can close import, and a side of flap valve is equipped with the axle and spring that flap valve closed hinged with cavity.
Described control device is an electromagnetic valve and a pressure switch, and the outfan of pressure switch and the control end of electromagnetic valve are connected with the time relay and power supply.
Advantage and the good effect that the utlity model has are: owing to add the valve of control urethral catheterization on catheter, make urine under certain pressure, just begin urethral catheterization, make bladder that the chance of expansion, contraction has been arranged like this, keep normal function, avoided the side effect of contracture of bladder, this in addition discontinuous urethral catheterization also makes the interior storage of urine time of urinal shorten greatly, reduces growing and retrograde infection of antibacterial, in addition this utility model also have simple in structure, the advantage that is easy to make.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
Among the figure: 1, catheter; 2, valve; 3, water ends folder; 4, urinal; 5, spring; 6, flap valve; 7, frustum projection; 8, pressure switch; 9, power supply; 10, the time relay; 11, electromagnetic valve.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, catheter 1 lower end is connected with urinal 4, the catheter lower end also is equipped with tongs 3, the valve 2 that control urine conducting is installed and closes in the catheter middle part, valve internal has a circular cylindrical cavity, the center that is equipped with in the cavity is shaped on the flap valve 6 of the frustum projection 7 of stopping up catheter, between flap valve and the valve cavity rotating shaft is installed, the spring 5 that flap valve is closed is installed in the rotating shaft, like this when urine reaches certain pressure, flap valve overcomes spring force and opens flap valve automatically, the urine conducting; Pressure disappears after urine is discharged, and flap valve sets back under the spring force effect, closes catheter.
As shown in Figure 2, on catheter 1, also can add control urine conducting and pressure switch 8 of closing and electromagnetic valve 11, be connected with the time relay 10 and power supply 9 at the outfan of pressure switch and the control end of electromagnetic valve.Like this when urine reaches certain pressure, pressure switch action turn-on power, power supply is given electricity by the time relay to electromagnetic valve, makes the electromagnetic valve action, the conducting urine; Pressure disappears after urine is discharged, the pressure switch return, and the time relay cut off the power supply after time-delay a period of time, made the electromagnetic valve return, closed catheter.
