Description
Technical field
This utility model belongs to technical field of medical instruments, especially a kind of automatic urethral catheterization discharge opeing control device device of using in cathing process and catheter.
Background technology
The process of human body micturition reflex: adult under normal circumstances, under the impact that detrusor of bladder is got excited at parasympathetic tone, be in light contraction state, intravesical pressure is made often to remain on 0.98kPa(10cmH2O), because bladder has larger extensibility, can return to very much after causing intrinsic pressure slightly rising and fall.When urine volume is increased to 400-500ml, intravesical pressure is just more than 0.98kPa(10cmH2O) and obviously raise (as shown in Figure 1).If intravesical urine volume is increased to 700ml, intravesical pressure is increased to 3.43kPa(35cmH2O thereupon) time, just there is Rythmic contractions characteristic in detrusor, urinates for also obviously increasing, but now also can control consciously to urinate.When intravesical pressure reaches 6.86kPa(70cmH2O) more than time, just there is significantly pain so that have to urinate.
Clinical treatment usually needing carry out urethral catheterization to patient is discharged to external by human urine, the urethral catheterization of present stage is normally inserted catheter and discharged intravesical urine by catheter passage, destroys the natural reflection process that human body is urinated.So to the unexpected tube drawing of patient of long-time intubate urethral catheterization, there will be the physiological reaction of urinating blunt or lose (namely occurring the situation of common urinary incontinence), this just needs to recover the human body physiological function of urinating.Circulation and blocking-up normally by controlling catheter before tube drawing in the process recovering controlled micturition physiological function allow patient's bladder collection urinate to make filling of bladder to recover mechanism of micturition step by step.But, this process need personnel control and operation, when patient's stupor or handicapped, monitor not in place easily cause the uncomfortable or damage of patient.
For described situation above, products application of the present invention can avoid patient to cause physiology of urinating blunt or lose because of intubate urethral catheterization in urethral catheterization.Be applied in the process of the physiological function that recovers to urinate and can reduce personnel control, avoid because of monitoring error, patient's stupor or handicapped discomfort or damage caused to patient.

Detailed description of the invention
Embodiment one: as shown in Figure 2, a kind of automatic urethral catheterization draining controller of this utility model, comprise shell 11 and pressure control switch 12, shell 11 is provided with the taper inner joint 13 for connecting urine collector and catheter and taper external tapping 14, be provided with the urinary pathway 15 running through taper inner joint and taper external tapping in shell 11, pressure control switch 12 is arranged in the urinary pathway of taper external tapping 14.This pressure control switch 12 be according to Human Physiology Micturition pressure be according to determine Micturition pressure switch.When intravesical urine pressure reaches Human Physiology Micturition pressure, Micturition pressure switch opens intravesical urine flows out; When intravesical urine pressure is less than Human Physiology Micturition pressure, Micturition pressure switch cuts out intravesical collection urine.Process of urinating simulates the physiological reaction of human body completely.
Above-mentioned pressure control switch can adopt different frame modes to realize, and is mainly described in the following two kinds mode in the present embodiment.
One, as shown in Figure 3,4, above-mentioned pressure control switch 12 is diaphragm structure, can adopt and carve type pressure-sensitive diaphragm, and this is carved type pressure-sensitive diaphragm and can open when pressure reaches Human Physiology Micturition pressure, and when opening, state as shown in Figure 4.
Two, as shown in Figure 5,6, above-mentioned pressure control switch also can adopt spring structure, be specially, pressure control switch comprises the spacing preiection 121 in the exit being fixed on taper external tapping urinary pathway, spring 122 and plunger 123, and the two ends of spring 122 connect spacing preiection 121 and plunger 123 respectively.The size of plunger 123 and the urinary pathway import department of taper external tapping 14 adapt, and be also provided with a urine discharge breach 124 in urinary pathway 15 near spring 122 and spacing preiection 121 junction.Further, pressure control switch 12 also comprises the plunger spacing ring 125 that is arranged on the exit of taper external tapping urinary pathway.
As shown in Figure 6, during use, discharge breach 124 owing to being provided with urine, when the pressure that plunger 123 is subject to reaches Human Physiology Micturition pressure, spring 122 is compressed into the exit of taper external tapping urinary pathway, namely opens and urinates.When pressure is less than Human Physiology Micturition pressure, plunger 123, under the elastic force effect of spring 122, remains on the import department of taper external tapping 14 urinary pathway, namely stops urinating.
Taper inner joint in the present embodiment and taper external tapping design according to the interface of existing catheter and urine collector completely, meet the connection request to excretion interface in " YY0325-2002 single use sterilized catheter ".Time below with this utility model practical application, the connection of each parts is further described.
As shown in Figure 7, the tapered external tapping 14 of this utility model automatic urethral catheterization draining controller 1 is connected with the taper inner joint 21 of existing catheter 2, and taper inner joint 13 is connected with the collecting terminal draining connector 31 of existing urine collecting 3.
Embodiment two: as shown in Figure 8, a kind of automatic drain catheter of this utility model, comprise saccule urinary catheter, saccule urinary catheter comprises the sacculus 41, conduit 42 and the joint 43 that are communicated with successively.Wherein, sacculus 41 is provided with urine import 44, and joint 43 is provided with balloon cavity interface 431 and exhaust chamber interface 432.The pressure control switch 433 can opened when pressure reaches Human Physiology Micturition pressure is provided with in exhaust chamber interface 432.The pressure control switch of the diaphragm structure that this pressure control switch 433 can adopt above-mentioned automatic urethral catheterization draining controller to use.
Certainly, as shown in Figure 9, the pressure control switch of the spring structure that the pressure control switch 433 be built in exhaust chamber interface 432 also can adopt above-mentioned automatic urethral catheterization draining controller to use.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to this utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
