Abstract
The utility model discloses a urinary catheter. The utility model can be fixed firmly when used, patients can feel comfort; when the urinary catheter is placed, the drainage is thorough without remnant urine. The urinary catheter is composed of an air sac, a low-level drainage side hole, a urinary catheter body, an aerating valve and an outer drainage interface. A thin cavity and a urinary catheter cavity are arranged in the urinary catheter body, and the air sac is positioned on the head end of the urinary catheter to be communicated with the aerating valve through the thin cavity. The low-level drainage side hole is communicated with the outer drainage interface through the urinary catheter cavity; the air sac is positioned on one side of the urinary catheter body, the low-level drainage side hole is positioned on the other side of the urinary catheter body, and the low-level drainage side hole is corresponding to the air sac.
Description
This utility model belongs to this technical field of medical catheter, particularly a kind of inclined to one side side Foley catheter.
The catheter of using clinically mainly contains two big classes, the one, ordinary urethral catheter, the 2nd, Foley's catheter now.Ordinary urethral catheter does not have inside and outside fixture, need during application to fix with rubber plaster stickup patient's pudendum and external genitalia position, its external orifice of urethra secretions inadequate drainage of back is fixed in fixing inconvenient and fixing not firm, easy slippage in addition, has increased the chance of patient's urinary tract infection.The Foley's catheter, in have air bag to fix, but its drain side opening is positioned at the air bag front, and when the indwelling catheter drainage of urine, its drain side opening is positioned at bladder central authorities, drain does not thoroughly have residual urine, increased the chance that infects, and formed easily that precipitate blocks the urinary catheter tube chamber in the urine, in addition the air bag of Foley's catheter be positioned at the urethral catheterization body around, volume is big, heavy to bladder irritation during use, patient's sense of discomfort is strong.It is 89213347 patent that an application number is arranged, and relates to a kind of internally-fixed catheter, and it is inner, and to play the head of blooming of fixation heavy to the stimulation of bladder.
This utility model provides a kind of inclined to one side side Foley catheter at above-mentioned the deficiencies in the prior art part, fixation when it uses, and patient's sense of discomfort is poor, and during indwelling catheter, drain does not thoroughly have residual urine.
This utility model is achieved through the following technical solutions: this catheter is made up of air bag, dependent drainage side opening, urethral catheterization body, charging valve, external drainage interface, thin chamber and urethral catheterization lumen are arranged in the urethral catheterization body, air bag is positioned at the head end of catheter and communicates with charging valve by thin chamber, the dependent drainage side opening communicates with the external drainage interface by urethral catheterization lumen, air bag is positioned at a side of urethral catheterization body, and the dependent drainage side opening is positioned at the opposite side of urethral catheterization body and relative with air bag.After the catheter head end inserts bladder, by charging valve by the gas injection of thin chamber or water in air bag, air bag is swelled, make catheter be difficult for deviating from, air bag is inclined to one side side, and is little to bladder irritation, sense of discomfort is poor.The position of dependent drainage side opening in bladder is low, during indwelling catheter, can make urine drainage thorough.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail: this catheter is by air bag (1), dependent drainage side opening (2), urethral catheterization body (3), charging valve (4), external drainage interface (5) is formed, thin chamber (6) and urethral catheterization lumen (7) are arranged in the urethral catheterization body (3), air bag (1) is positioned at the head end of urethral catheterization body (3) and communicates with charging valve (4) by thin chamber (6), dependent drainage side opening (2) communicates with external drainage interface (5) by urethral catheterization lumen (7), air bag (1) is positioned at a side of urethral catheterization body (3), and dependent drainage side opening (2) is positioned at the opposite side of urethral catheterization body (3) and relative with air bag (1).During use, the head end of catheter inserts bladder, by charging valve (4) by (6) gas injection of thin chamber or water in air bag (1), air bag (1) is swelled, generally after air bag (1) filled up, the peak of air bag (1) was 1.5～2.0cm apart from the diameter of the distance+urethral catheterization body of urethral catheterization body, just can make catheter be unlikely to deviate from from opening of bladder, air bag (1) is inclined to one side side, and is little to bladder irritation, sense of discomfort is poor.Dependent drainage side opening (2) is positioned at the opposite side of urethral catheterization body (3), and relative with air bag (1), and dependent drainage side opening (2) position in bladder is low like this, and drain does not thoroughly have residual urine and forms.General rearmost point when dependent drainage side opening (2) can be avoided the covered obstruction of dependent drainage side opening during than the about 0.5cm of rearmost point height of air bag (1), and drain is the most thorough.
Claims (1)
1, a kind of catheter, form by air bag, dependent drainage side opening, urethral catheterization body, charging valve, external drainage interface, thin chamber and urethral catheterization lumen are arranged in the urethral catheterization body, air bag is positioned at the head end of catheter and communicates with charging valve by thin chamber, the dependent drainage side opening communicates with the external drainage interface by urethral catheterization lumen, it is characterized in that air bag is positioned at a side of urethral catheterization body, the dependent drainage side opening is positioned at the opposite side of urethral catheterization body and relative with air bag.
