Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of diaphragm type Foley catheter.
Background technology
Foley catheter is a kind of apparatus of clinical conventional drainage of urine, and body front portion is provided with the urethral catheterization of connection tube chamber
Hole, and for preventing catheter front end from departing from the air bag of bladder, body rear portion is provided with the inflation inlet of communicated air bags, and end is
Urination mouth, when body front portion is inserted to correct position in bladder, being inflated through inflation inlet into air bag makes its expansion realize fixation.
On traditional Foley catheter, urethral catheterization hole is constantly in conducting state, bladder a little urine with urination mouth
Will be discharged, this results in bladder and is chronically at emptying state, on bionics for, the change of intravesical pressure is conducive to protecting
Its function is held, and the change of intravesical pressure is realized in the process of urine accumulation, discharge, bladder is chronically at emptying shape
State, can decline the stress diastolic function of detrusor urinae of bladder, inside and outside sphincter, and urine storage function, the row of bladder can be caused when serious
Hyporeflexia is urinated, and then causes bladder function to be gradually reduced, bladder function disuse atrophy is caused eventually.
Also there is the Foley catheter for being provided with pressure sensor, processing module and electric control valve at present, pass through pressure sensing
Device detects intravesical pressure, is received by processing module, the detection data of processing pressure sensor, to control electric control valve to open and close,
So that the urine of bladder still has the process of accumulation, bladder is retained the change of internal pressure, maintain bladder function；But urine pH value
Fluctuated between 4.5-8.0, acid-base property fluctuates conference and electronic device generation corrosion, and its operation must be supported by power supply, reliably
Property is low, and the usage cycles of Foley catheter are generally one week, it is impossible to reuse, the increase of electronic device greatly improved
The use cost of Foley catheter, and complicated, operation inconvenience.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of diaphragm type Foley catheter, existing air bag urethral catheterization can be solved
Pipe realizes pipeline switching using electronic devices such as pressure sensor, processing module and electric control valves, to maintain bladder function, leads
Cause reliability is low, cost is high, complicated, unhandy problem.
The present invention is achieved through the following technical solutions：
A kind of diaphragm type Foley catheter, its body front portion is provided with air bag and set with the urethral catheterization hole of tube chamber, body rear portion is connected
There is the inflation inlet of communicated air bags, end is urination mouth, and arch is connected with the urethral catheterization hole side body towards body end
Valve mechanism is provided with flexible sheet, the tube chamber, the valve element of the inwall connecting valve mechanism of the flexible sheet drives it
Action, makes valve mechanism on or off.
The further scheme of the present invention is that the flexible sheet and valve element respectively have two, the valve mechanism at least provided with
Two imports, described two flexible sheets are symmetricly set in body both sides, each one valve element of connection, the movement of each valve element,
Open or close at least one import.
The further scheme of the present invention is that the flexible sheet and valve mechanism respectively have two, and the tube chamber passes through barrier film
It is divided into two chambers, the body front portion is provided with least two urethral catheterization holes connected respectively with two chambers, described two
Flexible sheet is connected on the corresponding body of two chambers, and two valve mechanisms are respectively arranged in two chambers.
The further scheme of the present invention is that described two valve mechanisms are staggered in two chambers.
The further scheme of the present invention is that the valve mechanism includes valve body and valve element, and the valve body edge sealing connects
It is connected on lumen wall, the valve body and is provided with spool chamber, and be respectively communicated with the inlet and outlet of spool chamber, the valve element is set
It is placed in spool chamber.
The further scheme of the present invention is to be provided with spool bore on the valve element, with the movement of valve element, the valve element
Hole overlaps or staggered with import, outlet, realizes the on or off of valve mechanism.
The further scheme of the present invention is that the body has outer layer and internal layer to be composited.
The further scheme of the present invention is that the flexible sheet connects valve element by spring.
The advantage of the present invention compared with prior art is：
First, the altitude simulation urine storage of bladder, the physiological function of urination, according to intravesical pressure come automatically adjust bladder urine storage and
Urination reaction, reduces the sense of discomfort of patient, improves the tolerance of patient, reduces the complication after catheter use；
2nd, when intravesical pressure is more than the flexible sheet tolerance range of arch, flexible sheet is recessed to body direction, drives valve element
Action makes valve mechanism conducting discharge urine, electronic device is not used completely, reliability is high, cost is low, simple in construction, operation side
Just；
3rd, two flexible sheets, valve element and import, can reduce that single flexible sheet is damaged or spool jam or import are blocked
Cause urine can not discharge the healthy risk of influence sufferer；
4th, tube chamber is divided into by two chambers by barrier film, the larger foreign matter of volume can be prevented while blocking two imports, entered
One step reduction urine can not discharge the healthy risk of influence sufferer；
5th, two valve mechanisms are staggered, limitation of the reduction installing space to valve mechanism size, advantageously reduce installation difficult
Degree, expands import, outlet size, and reduction blocks risk, makes urination more smooth；
6th, overlap or stagger with import, outlet by spool bore, realize the on or off of valve mechanism, urine and foreign matter are not
Spool chamber can be entered, the sealing between valve element and valve element cavity wall is not interfered with, further improve reliability；
7th, using spring performance, flexible sheet promote valve core movement when there is hysteresis quality, can evade a part because of abdominal pressure suddenly
Pseudo- urination caused by increase, causes to extend urination time because of its hysteresis quality, is drained beneficial to urine, bladder urination of more fitting
Physiological effect；
8th, this catheter is particularly suitable for use in neurogenic bladder patient, is that it maintains the urine storage of bladder, urinary function, remolds wing
The neural reflex of Guang, improves its curative effect, shortens its course for the treatment of and is supported there is provided Urinary functional test and Mechanics of Machinery.
