Abstract

The utility model discloses a multi-cavity urethral catheter, which comprises a urethral catheterization cavity, a gas bag and a gas bag cavity. A drainage hole is arranged at the top end of the urethral catheterization cavity, the gas bag is annularly placed on the outer wall of the urethral catheter and is connected with the gas bag cavity inside the urethral catheter, a balloon catheter is connected with the tail end of the gas bag cavity, and a gas charging valve is arranged at the tail end of the balloon catheter; the urethral catheter is also provided with a cavity A, a side hole is formed at the front end of the urethral catheter and is connected with the cavity A, and the tail end of the cavity A is connected with the catheter. When blood clots or secretions inside the bladder clog the drainage hole, flushing fluid is introduced from the water inlet hole to dilute and scatter the blood clots or secretions, and the diluted and scattered blood clots or secretions are discharged out of human body from the drainage hole and the side hole, so as to reduce the unsmooth micturition phenomenon airing from the blockage of the drainage hole by the blood clots or secretions, reduce the frequency of reintubation, and relieve the additional pains on patients.

Description

A kind of multi-cavity catheter
Technical field
This utility model belongs to medical device, relates in particular to a kind of multi-cavity catheter with scale side opening and scale groove.
Background technology
Indwelling catheter is clinical practice one of nursing procedure comparatively widely, at present disposable two-chamber or three chamber silica gel Foley catheters of adopting more, this catheter requires female patients to insert urethra 4-6cm when operation, patient male inserts urethra 20-22cm, see that urine inserts 7-10cm again after catheter flows out, and in air bag, inject and corresponding 0.9% sodium chloride solution of this catheter bag volume, be used for the conduction hole of catheter is fixed on intravesical.At present following problem is arranged in the clinical use of urinary catheter: 1, the urinary catheter front end has 1-2 conduction hole, when drainage of urine, if patient's intravesical is hemorrhage more, is easy to then cause that the conduction hole of urinary catheter stops up, and is unfavorable for the discharge of urine; 2, during indwelling catheter because urinary catheter stimulates urethra to be easy to generate secretions, for the breeding of antibacterial provides the place, be easy to cause urinary tract infection if drain is insufficient; Increased patient's additional misery.
The utility model content
Technical problem to be solved in the utility model provides a kind of Foley catheter, when the pleural drainage hole plug, blood or secretions well can be carried out drain.
In order to address the above problem, this utility model is taked following technical scheme: a kind of multi-cavity catheter, comprise: urethral catheterization chamber, air bag and airbag chamber, top, described urethral catheterization chamber is provided with conduction hole, described air bag annular places the interior airbag chamber of catheter outer wall and catheter to be connected, the terminal balloon catheter that connects of airbag chamber, the balloon catheter end is provided with charge valve; Described catheter outer wall is provided with side opening, and described side opening is connected with the A chamber of catheter inside, and the A chamber is terminal to be connected with conduit.
Preferably, described catheter outer wall is established the scale groove.
Preferably, described scale inside grooves is carved with scale.
Characteristics of this urinary catheter or advantage: 1, during indwelling catheter,, be beneficial to the drain of urine, reduce the generation of plugging by increasing 1-2 side opening at the urinary catheter head end.And can in the urinary catheter passage, inject flushing liquor, flushable intravesical secretions, blood, pus help the drain control and infect; Inject relieving spasm to stop pain or topical anesthetic cream, treatment cystospasm etc. can effectively alleviate patient's misery; 2. after placing this urinary catheter, endo-urethral secretions can be excreted from urethra by the side opening in the urinary catheter, the drain meeting is more abundant, thereby effectively prevents and treats the relevant urinary tract infection of indwelling catheter; 3, by on urinary catheter, increasing graduated way, can improve the degree of accuracy of clinical manipulation, reduce patient's additional misery.
Description of drawings
Fig. 1 is this utility model multi-cavity catheter structural representation;
Fig. 2 is the described graduated multi-cavity catheter structural representation that has.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, this utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to figure 1, catheter 11 shown in Figure 1 is the made circular pipe of silica gel, catheter inside is provided with three chambeies, be provided with 1 or 2 conduction holes 12 on 18 tops, urethral catheterization chamber of catheter, urethral catheterization chamber end is an apopore, air bag 14 is enclosed within on the outer wall apart from the about 5cm in catheter top place, and the outer wall of being close to catheter, airbag chamber one end in the catheter passes the catheter outer wall and is connected with air bag 14, the other end of airbag chamber is connected with balloon catheter 15, and the balloon catheter end is provided with charge valve 16; A chamber side is provided with side opening 13, and side opening is positioned at conduction hole 4 to 18cm places, and according to concrete demand, side opening 13 can be set to a plurality of.The A chamber is terminal to be connected with conduit 17, is used to import flushing liquor or input treatment medicinal liquid.
With reference to figure 2, in order to control the length that catheter inserts urethra, at the catheter outer wall a plurality of scale grooves 19 are set, scale is carved with in groove 19 inside, for example: from the urinary catheter top to 25cm, do a scale groove every 1cm, promptly engrave scale in the groove respectively at 1cm, 2cm, 3cm, 4cm.....25cm place.
During actual nursing procedure, intravesical is inserted on the catheter top, inflate to air bag by airbag chamber, the air bag of expansion is stuck in intravesical, if blood or endo-urethral secretions stop up conduction hole when dredging urine, can import cleanout fluid from conduit, cleanout fluid flows out from the side opening in A chamber, break up and stop up conduction hole blood and secretions on every side, Xi Shi blood and secretions are discharged in the body simultaneously from side opening and drain then.
The technical scope of this utility model is not limited to the content on the description, also has the concrete technical application scheme of much determining according to its claim.The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
