Abstract
The utility model relates to a prostate perfusion drainage tube, which comprises a tube body. A tube cavity of an air sac of a ball part of a urethra, a tube cavity of an air sac of a neck part of a bladder, a medicine-injecting tube cavity and a negative pressure drainage tube are arranged in the tube body. The air sac of the ball part of the urethra and the air sac of the neck part of the bladder are arranged on the front part of the tube body to be respectively coated around the tube body; an opening is arranged on the tail end of the negative pressure drainage tube to be used as an interface of a negative pressure device to be connected with the negative pressure device when the utility model is used. Compared with the prior art, the utility model is characterized in that an original urinary catheter cavity is cancelled, and the negative pressure drainage tube is additionally arranged on the utility model to enable the utility model to solve the problem of back flow of physic liquor, and simultaneously, the original functions of the prior art can be finished; the utility model also adds a function of drainage for prostatitis secretion.
Description
This utility model belongs to toward the interior medical apparatus and instruments of introducing medium of body cavity, and what be specifically related to is a kind of prostate infusion drainage catheter.
In the topical therapeutic of prostatitis and other attached property inflammation, a kind of topical conduit that professor's Cheng Huaijin invention is arranged, be Chinese patent 88212101 disclosed chronic prostatitis topical conduits, this conduit comprises four chambeies and two air bags, it is bladder neck air bag tube chamber, airsac tube chamber, urethra bulb, the injection tube chamber, urinate tube chamber and urethra bulb air bag, the bladder neck air bag, the invention of this conduit provides a kind of brand-new thinking for prostatitic treatment, but in clinical practice, this conduit exists a shortcoming, dabbling exactly medicinal liquid easily backflows to bladder, thereby influence is to the therapeutic effect of prostatic part, this is that the existence of the urethral catheterization lumen that communicates with bladder because of front end causes, the existence of urethral catheterization lumen can reduce intravesical hydraulic pressure, is unfavorable for the sealing process of bladder neck air bag to neck of bladder.
The purpose of this utility model is to provide a kind of and can overcomes above-mentioned conduit and have the backflow prostate infusion drainage catheter of shortcoming of medicinal liquid.
The purpose of this utility model is achieved in that this utility model comprises a body, comprise airsac tube chamber, urethra bulb, bladder neck air bag tube chamber and injection tube chamber in the body, the front portion of body be provided with urethra bulb air bag and bladder neck air bag wrap in respectively body around; The front end of airsac tube chamber, urethra bulb and bladder neck air bag tube chamber passes to urethra bulb air bag and bladder neck air bag respectively, and 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 two air bags, and its tail end is opened on the body afterbody and leads to outside the body; Also comprise the negative pressure drainage tube chamber in the body, the front opening of negative pressure drainage tube chamber is on the tube body wall between two air bags, and its tail end opening is the negtive-pressure implement interface, opens in the body afterbody.
Technique effect of the present utility model is: this utility model has been cancelled the urethral catheterization lumen in the correlation technique conduit on the one hand, 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; Increased the negative pressure drainage tube chamber of front opening on the other hand in prostatic part, make prostatic urethra produce negative pressure by negtive-pressure implement, make the intravital rheuminess thing of prostate gland by drain to urethra, thereby help prostatitic treatment more, increased therapeutic effect.In a word, this utility model not only solves the medicinal liquid problem of backflowing when finishing the conduit original function of correlation technique, also increased the drain function to the prostatitis sexual secretion.
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, this utility model embodiment is a body, four tube chambers such as airsac tube chamber, urethra bulb 1, bladder neck air bag tube chamber 2, injection tube chamber 3 and negative pressure drainage tube chamber 4 are arranged in the body, the front portion of body be provided with urethra bulb air bag 5 and bladder neck air bag 6 wrap in respectively body around; Body is divided into the catheter holder 7 and the outer field catheter jacket 8 of internal layer, being rubber makes, but the hardness ratio catheter jacket 8 of catheter holder 7 is big, catheter holder 7 mainly plays support and fixes four tube chambers, airsac tube chamber, urethra bulb 1, bladder neck air bag tube chamber 2, injection tube chamber 3 and negative pressure drainage tube chamber 4 mainly are positioned at catheter holder 7, and catheter jacket 8 makes the conduit profile be shaped on the one hand, and comparatively softness does not cause it too painful when conduit inserts patient's urethra on the one hand; The body afterbody forms several tubulose branches from rat, the rear that comprises four tube chambers such as airsac tube chamber, urethra bulb 1, bladder neck air bag tube chamber 2, injection tube chamber 3 and negative pressure drainage tube chamber 4 in each branch respectively is provided with apparatus derivatorius and is convenient to operation and distinguishes each tube chamber.
As shown in Figure 1, the front end of airsac tube chamber, urethra bulb 1 and bladder neck air bag tube chamber 2 passes to urethra bulb air bag 5 and bladder neck air bag 6 respectively, and their tail end extends to the branch of body afterbody respectively and passes to outside the body and at the mouth of pipe place Non-return air valve 9 is housed respectively; The front end of injection tube chamber 3 and negative pressure drainage tube chamber 4 is established several respectively and is opened on the tube body wall between two air bags, and their tail end opening also extends to the branch of body afterbody respectively and passes to outside the body, and the tail end opening of negative pressure drainage conduit 4 is the negtive-pressure implement interface.
During use, this utility model embodiment is inserted patient's urethra, allow the position between two air bags be positioned at prostatic urethra, by Non-return air valve 9 per urethra bulb air bag tube chambers 1 and bladder neck air bag tube chamber 2 aeration in two air bags, make the relative blind chamber of prostatic urethra after urethra bulb air bag 5 and bladder neck air bag 6 are full, the pressure that utilizes injection to be produced by injection tube chamber 3 enters in the prostate lumen of gland medicine liquid irrigation, after the perfusion, make prostatic urethra produce negative pressure by the negtive-pressure implement that is connected with negative-pressure drainage tube 4, the drain of the intravital rheuminess thing of prostate gland to urethra, is excreted with urine later on.
