Abstract
The utility model discloses a urinary catheter for pressure measurement in the technical field of clinic medical equipment. The urinary catheter comprises a catheter body made of an elastic material, an air bag is arranged on the periphery close to the upper end of the catheter body, a urinary catheterization hole is formed in the center of the catheter body, an air bag hole communicated with the air bag is formed in the catheter wall outside the urinary catheterization hole, the lower end of the air bag hole is connected with an air feed and exhaust joint through a branch pipe I, a pressure hole and a liquid feed hole are formed in the catheter wall outside the urinary catheterization hole, the upper ends of the pressure hole and the liquid feed hole are extended into the upper end part of the catheter body, and the lower end of the pressure hole is connected with a pressure measurement joint through a branch pipe II; and a transfusion joint is connected to the lower end of the liquid feed hole through a branch pipe III. During use, a far end of the urinary catheter is closed, a pressure sensor is connected onto the pressure measurement joint, a syringe is connected onto the transfusion joint, an injection is injected into a bladder, then the internal pressure of the bladder can be displayed on a pressure gauge through the pressure sensor, and internal pressure measurement of the bladder is finished. Therefore, the internal pressure of the bladder can be measured more accurately, faster and more safely, and parameter reference is provided for treatment.
Description
Technical field
This utility model belongs to clinical treatment technique with the apparatus field, relates to specifically a kind of catheter.
Background technology
In prior art, there is a kind of catheter, its structure comprises the body of being made up of elastomeric material, body is provided with air bag near upper end position periphery, body center is provided with urethral catheterization hole, in tube wall outside urethral catheterization hole, be provided with the pneumatopyle communicating with air bag, pneumatopyle lower end is connected with intake and exhaust joint through arm one.Catheter is from urethra inserts bladder, and urine can be discharged by urethral catheterization hole, to air bag air feed, makes its expansion fixing by intake and exhaust joint, pneumatopyle.In the time that measuring intravesical pressure, conventionally take by needs two kinds of ways: the one, and catheter far-end is closed, and uses disposable transfusion device directly to thrust urethral catheterization hole, splashes into after normal saline 50ml, uses meter ruler to measure water-column.Its shortcoming: it is poor that medical worker operates compliance; Repeated measurement is repeatable poor; The stability of hand dipping is not good enough; Urine in part urethral catheterization hole refluxes, and may have the risk of infection; The 2nd, catheter far-end is closed, and uses threeway to be connected between catheter and urinal, connects transfusion device and pressure transducer by threeway.Its weak point is: threeway is connected difficulty with catheter interface, connective stability is not good enough; In part urethral catheterization hole, urine refluxes, and has the risk of PI.
Utility model content
In order to overcome existing catheter in the deficiency when measuring intravesical pressure, can accurately, fast, more safely measure intravesical pressure, the catheter that this utility model provides a kind of novel pressure measurement to use.
The purpose of this utility model is achieved in that the catheter that a kind of pressure measurement is used, comprise the body of being made by elastomeric material, body is provided with air bag near upper end position periphery, body center is provided with urethral catheterization hole, in tube wall outside urethral catheterization hole, be provided with the pneumatopyle communicating with air bag, pneumatopyle lower end is connected with intake and exhaust joint through arm one, in tube wall outside described urethral catheterization hole, be provided with pressure tap and inlet opening, pressure tap and inlet opening upper end extend to body upper end, and pressure tap lower end is connected with pressure measuring tie-in through arm two; Inlet opening lower end is connected with infusion connector through arm three.
When this utility model uses, by patient's clinostatism of making even, under sterile working, first, body is inserted into bladder by per urethra, inflates via arm one by intake and exhaust joint to pneumatopyle, make airbag inflation fix catheter, intravesical urine can be drawn by urethral catheterization hole.In the time carrying out pressure measurement, first catheter far-end is closed, pressure transducer is connected on pressure measuring tie-in, again syringe is connected on infusion connector, then injection is injected into intravesical, intravesical pressure will be presented on pressure measuring instruments by pressure transducer, completes the measurement to intravesical pressure, thereby reaches the object of indirect measurement intra-abdominal pressure.This device has designed independently inlet opening in body, by arm tee joint to infusion connector.Like this, injection needn't thrust urethral catheterization hole by syringe, but directly from inlet opening input, reflux and may cause the risk of infection thereby effectively stopped the urine in urinary catheter, also solved can not repeated measurement intravesical pressure problem; Meanwhile, in body, design independently pressure tap, be communicated on pressure measuring tie-in by arm two.Like this, just can solve pressure transducer and can not stablize the problem being connected with catheter.This apparatus structure is simple, can accurately, fast, more safely measure intravesical pressure, for treatment provides corresponding parameter foundation.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is that A-A of Fig. 1 is to view.
Wherein, 1. body, 2. intake and exhaust joint, 3. arm one, 4. pneumatopyle, 5. air bag, 6. urethral catheterization hole, 7. inlet opening, 8. arm two, 9. arm three, 10. infusion connector, 11. pressure measuring tie-ins, 12. pressure taps.
The specific embodiment
As shown in Figure 1, pressure measurement catheter of the present utility model, comprise the body 1 of being made by elastomeric material, body 1 is provided with air bag 5 near upper end position periphery, body 1 center is provided with urethral catheterization hole 6, in tube wall outside urethral catheterization hole 6, be provided with the pneumatopyle 4 communicating with air bag 5, pneumatopyle lower end is connected with intake and exhaust joint 2 through arm 1, and independent pressure tap 12 and the inlet opening 7 arranging in tube wall outside urethral catheterization hole 6, pressure tap 12 and inlet opening 7 upper ends extend to the upper end of body 1, pressure tap 12 lower ends are connected with pressure measuring tie-in 11 through arm 28, inlet opening 7 lower ends are connected with infusion connector 10 through arm 39, pressure tap 12 and inlet opening 7 are arranged in parallel within the tube wall outside urethral catheterization hole 6, arrangement mode is not limit.
In the time using this device, patient's clinostatism of making even, under sterile working, first, body 1 is inserted into bladder by per urethra, by intake and exhaust joint 2 via arm 1 to the interior inflation of pneumatopyle 4, air bag 5 is expanded and fixes catheter, when normal use, can, by urethral catheterization hole 6, intravesical urine be drawn.While needing pressure measurement, first catheter far-end is closed, then pressure transducer is connected on pressure measuring tie-in 11, again syringe is connected on infusion connector 10, injection is injected into intravesical, intravesical pressure will be presented on pressure measuring instruments by pressure transducer, completes the measurement to intravesical pressure.In above-mentioned work process, need to close a certain passage time (inlet opening, pressure tap, pneumatopyle), can will after corresponding arm doubling, clamp with clip, get final product cutting-off liquid flow or air-flow, take off clip, under elastic reaction, can open voluntarily respective channel.
This utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of this utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
