Abstract
The utility model relates to a three-bag four-cavity prostate perfusion catheter. The interior of a catheter body comprises four catheter cavities, namely an air sac catheter cavity 1 for the ball part of a urethra, an air sac catheter cavity 2 for the prostate part of the urethra, an air sac catheter cavity 3 for the neck part of a bladder, a medicine-injecting catheter cavity 4, etc., wherein an air sac 5 for the ball part of the urethra is arranged at the front part of the catheter body; an air sac 7 for the prostate part of the urethra and an air sac 6 for the neck part of the bladder are respectively arranged around the catheter body; an opening at the tail end of the medicine-injecting catheter cavity 4 is connected with a medicine-injecting device when the utility model is used. The urinary catheter cavity of the existing catheter is cancelled by the three-bag four-cavity prostate perfusion catheter, and the air sac catheter cavity for the prostate part of the urethra is added, so the problem that physic liquor flows backwards to the bladder is effectively solved; simultaneously, the sealing function of the air sac for the neck part of the bladder to the neck part of the bladder is enhanced.
Description
This utility model belongs to toward the interior medical apparatus and instruments of introducing material of body cavity, and what be specifically related to is a kind of three capsules, four chamber prostate infusion conduits.
In the topical therapeutic of prostatitis and other accessory sex gland inflammation, once used a kind of conduit of topical, i.e. the conduit of Chinese patent 88212101 disclosed chronic prostatitis topicals.This conduit comprises four chambeies and two air bags, i.e. bladder neck air bag tube chamber, airsac tube chamber, urethra bulb, injection tube chamber and the tube chamber of urinating, urethra bulb air bag and bladder neck air bag.The invention of this conduit provides a kind of new thinking for prostatitic treatment, but in clinical practice, the medicinal liquid of this catheter perfusion easily backflows to bladder, thereby makes prostatic part not obtain due treatment.This is because the existence of the urethral catheterization lumen that front end communicates with bladder can reduce intravesical hydraulic pressure, is unfavorable for the sealing process of bladder neck air bag to neck of bladder; And, under the effect of drug infusion pressure, understand move left and right, thereby can not finish sealing process to bladder neck because the bladder neck air bag is an elastic soft.
The purpose of this utility model is that the deficiency at above-mentioned conduit provides a kind of backflow three capsules, four chamber prostate infusion drainage catheters of bladder of medicinal liquid that in use can prevent.
The purpose of this utility model is achieved in that three capsules, four chamber prostate infusion conduits of the present utility model, it is characterized in that catheter tube comprises the catheter holder and the outer field catheter jacket of internal layer, is provided with airsac tube chamber, urethra bulb, prostatic urethra air bag tube chamber, bladder neck air bag tube chamber and injection tube chamber in the catheter holder of body; The front portion of body be provided with urethra bulb air bag, bladder neck air bag and prostatic urethra air bag wrap in respectively body around, the front end of airsac tube chamber, urethra bulb, bladder neck air bag tube chamber and prostatic urethra air bag tube chamber passes to urethra bulb air bag, bladder neck air bag and prostatic urethra air bag respectively, their tail end is opened on the body afterbody and passes to outside the body, and at the mouth of pipe Non-return air valve is housed respectively; The front opening of injection tube chamber is on the tube body wall between urethra bulb air bag and the prostatic urethra air bag, and its tail end is opened on the body afterbody and leads to medicine injecting device outside the body.
Three capsules, four chamber prostate infusion conduits of the present utility model, described body can comprise the catheter holder and the outer field catheter jacket of internal layer, catheter holder mainly plays support and fixes four tube chambers, and airsac tube chamber, urethra bulb, prostatic urethra air bag tube chamber, bladder neck air bag tube chamber and injection tube chamber mainly are positioned at catheter holder.And catheter jacket on the one hand makes the molding of conduit profile, and soft smooth comparatively, reduces painful when conduit inserts patient's urethra; The hardness ratio catheter jacket of general catheter holder is big.The material of body is generally all selected rubber (latex) for use.
Three capsules, four chamber prostate infusion conduits of the present utility model, can also form several tubulose branches from rat at described body afterbody, comprise the rear of four tube chambers such as airsac tube chamber, urethra bulb, prostatic urethra air bag tube chamber, bladder neck air bag tube chamber and injection tube chamber in each branch respectively.Apparatus derivatorius is set, is convenient to operation and distinguishes tube chamber everywhere.
Three capsules, four chamber prostate infusion conduits of the present utility model, general opening on the front tube body wall of described injection tube chamber is one.
Three capsules, four chamber prostate infusion conduits of the present utility model owing to the urethral catheterization lumen of having got rid of in the existing conduit, utilize the intravesical pool stream pressure that urine and micturition reflex produced to strengthen the sealing process of bladder neck air bag, thereby prevent that medicinal liquid from backflowing to intravesical; The opposing party aspect, the existence of prostatic urethra air bag, can when dabbling drug, hinder the direct effect of injection pressure to the bladder neck air bag, thereby reduced the stressed of bladder neck air bag, keep the stable and sealing process of bladder neck air bag to greatest extent, thereby strengthened the sealing effectiveness of urethra prostate section when pouring at bladder neck.Help medicine so more and pour in the body of prostate, improve clinical therapeutic efficacy; Contrast agent can also be fed in the prostate lumen of gland by medicine-injecting cavity, finish prostatic contrast examination.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the section of structure of this utility model embodiment.
As shown in Figure 1, three capsules, four chamber prostate infusion conduits of the present utility model, body is inner conductor support 8 and the outer conductor overcoat of being made by latex 10, is provided with airsac tube chamber, urethra bulb 1, prostatic urethra air bag tube chamber 2, bladder neck air bag tube chamber 3 and injection tube chamber 4 in body; Anterior urethra bulb air bag 5, bladder neck air bag 6 and the prostatic urethra air bag 7 that is provided with of body wrap in respectively body around.The front end of airsac tube chamber, urethra bulb 1, bladder neck air bag tube chamber 3 and prostatic urethra air bag tube chamber 2 passes to urethra bulb air bag 5, bladder neck air bag 6 and prostatic urethra air bag 7 respectively, their tail end is opened on the body afterbody and passes to outside the body, and at the mouth of pipe Non-return air valve 9 is housed respectively; The front opening of injection tube chamber 4 is on the tube body wall between air bag 7 and the air bag 5, and its tail end is opened on the body afterbody and leads to outside the body external medicine injecting device.
During use, three capsules, four chamber prostate infusion conduits of the present utility model are inserted patient's urethra, allow the portion between three air bags be positioned at prostatic urethra, by check valve 9 through bladder neck air bag tube chamber 3 aeration in air bag, the bladder neck air bag is outwards pullled conduit after filling makes it be fixed in bladder neck, per urethra prostatic part air bag tube chamber 2 aeration in air bag again, reinforce the sealing process of bladder neck air bag to bladder neck, by check valve 9 per urethra bulb air bag tube chambers 1 aeration in air bag, like this, bladder neck air bag 6, make the relative blind chamber of prostatic urethra after prostatic urethra air bag 7 and urethra bulb air bag 5 are full, the full intensity of prostatic urethra air bag 7 progressively reduces after drug infusion begins, and finishes this step by the slow venting of check valve 9.Go into the prostate lumen of gland by the pressure messenger drug perfusion that medicine-injecting cavity 4 utilizes injection to be produced.
