Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of magnetic control urethra valve.
Background technique
Clinically by stress incontinence (Stress Urinary Incontinence) be defined as sphincter by
Damage, the abdominal pressures such as sneeze or cough will appear involuntary urine and leak from orificium urethrae externum when increasing.Symptoms are cough, sneeze
Do not overflow independently urine when increasing with abdominal pressures such as laughs；When sign is abdominal pressure increase, it can observe that urine does not outflow from the urethra automatically.
The patient of the urinary incontinence is unable to control urination time, and will lead to the complication such as perineum, sacrococcygeal region dermatitis and pressure ulcer,
Serious torment not only is brought to the physiology of patient and psychology, also family is caused greatly to bear.
The treatment method mainly used at present has merging catheter, is controlled, is performed the operation etc. with drug, but these nothings
It doubts and causes great physiology and psychology to torment uracratia patients.Although currently a popular artificial urinary sphincters (AUS 800)
It solves this Medical problems to a certain extent, but since manual operation causes device to shift, needs the probability of second operation
It is high；And to will cause urethra dispirited and rotten to the corn for closure urethra for a long time for device.
In view of this, designing, a kind of structure is simple, operation is simple, biocompatibility is high, safe and reliable and can periodically discharge
The device of urethra is just of great significance to simulate the function of sphincter urethrae.
Summary of the invention
Present invention aims to overcome that the shortcomings that prior art and deficiency, provide a kind of magnetic control urethra valve, are avoided that disease
The problem of people is independently manually operated and device is brought to shift, while the risk for needing second operation is reduced, it is periodically opened by magnetic force
Urethral atrophy and rotten to the corn occurrence probability can be reduced by closing urethra.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of magnetic control urethra valve, including being fixed on the Suprapubic implanted component of human body and positioned at external magnetic element, institute
Stating implanted component includes the left valve barrel and right valve barrel being connected, and left valve barrel is in the side that is in contact with right valve barrel equipped with left through slot, the right side
Valve body is equipped with the right through slot matched with left through slot, and the bottom of left through slot is equipped with left rubber mat, and the bottom of right through slot is equipped with right rubber mat,
Human urethra is between left through slot and right through slot；Left valve barrel is equipped with the guide channel being connected with left through slot, guide channel
Interior to be equipped with elastic element and permanent magnet spool, elastic element is given the extruding force of left rubber mat to the right by permanent magnet spool and is made
Left rubber mat and right rubber mat clamp human urethra；Magnetic element makes and with compression elastic element after permanent magnet spool phase separation
It obtains left rubber mat and right rubber mat loosens human urethra.
From the foregoing, it will be observed that the working principle of the invention: when urine storage, the elastic element in guide channel in the raw, bullet
Property element push permanent magnet spool squeeze left rubber mat to the right, press off urethra；When urination, magnetic element is placed in human body lower abdomen, magnetic
Property element makes left rubber mat set back and with compression elastic element after permanent magnet spool phase separation, and human urethra is put
Pine removes magnetic element so as to urinate after urination, elastic element restores nature, and urethra restores closure.
In conclusion magnetic element is placed in human body lower abdomen by the present invention can periodically be opened and closed urethra, the autonomous hand of patient is avoided
The problem of moving operation and device brought to shift, while reducing the risk for needing second operation；Urine is periodically opened and closed additionally by magnetic force
Road can reduce urethral atrophy and rotten to the corn occurrence probability, easy to operate, be easy to use.
As an improvement of the present invention, the left rubber mat and right rubber mat are made of medical silica-gel.
As an improvement of the present invention, the elastic element is elastomeric pad or spring.
As an improvement of the present invention, the magnetic element is permanent magnet.
Compared with prior art, the invention has the following advantages that
Magnetic element is placed in human body lower abdomen by the present invention can periodically be opened and closed urethra, and patient is avoided independently to be manually operated and band
The problem of carrying out device displacement, while reducing the risk for needing second operation；
Urethra is periodically opened and closed additionally by magnetic force can reduce urethral atrophy and rotten to the corn occurrence probability, easy to operate, convenient
It uses.
Detailed description of the invention
Fig. 1 is the schematic diagram of magnetic control urethra valve of the present invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.It is understood that tool described herein
Body embodiment is used only for explaining the present invention rather than limiting the invention.It also should be noted that for the ease of retouching
It states, only some but not all contents related to the present invention are shown in the drawings.
Embodiment
Referring to FIG. 1, a kind of magnetic control urethra valve, including be fixed on the Suprapubic implanted component 200 of human body and be located at external
