Description
Technical Field
The utility model relates to a medical apparatus technology especially relates to a technique of taking and intentionally extracting damage-proof type catheter outward.
Background
The catheter is a hose which is inserted into the bladder through the urethra to drain urine, the catheter is usually made of natural rubber, silicon rubber or polyvinyl chloride, the front part of the catheter is provided with an air bag, after the catheter is inserted into the bladder, the air bag at the front part is inflated to expand the catheter, and the position of the catheter can be fixed by utilizing the air bag, so that the catheter is not easy to drop when being kept in the bladder.
However, some unconscious patients may perform the action of pulling out the catheter by themselves after inserting the catheter, and some patients may also pull out the catheter by accident by themselves because of forgetting that the catheter is fixed on the patient bed. In the process of accidentally pulling out the catheter, the bladder and the urethra are seriously damaged by tearing and pulling injuries of the air bag.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that an accidental pulling-out injury-preventing type catheter that has that can not harm bladder and urethra when accidentally pulling out is provided.
In order to solve the technical problem, the utility model provides a take and intentionally extract damage-preventing type catheter, including soft catheter body, the front portion of catheter body is equipped with the gasbag, and the rear portion of catheter body is equipped with pneumatic valve, its characterized in that:
the outer wall of the outer air bag is coated with a layer of elastic, breathable and permeable water seepage protective film;
the catheter body is provided with two air valves at the rear part, wherein one air valve is an inner-layer air valve, the other air valve is an outer-layer air valve, the inner-layer air valve is communicated with the inner-layer air bag, and the outer-layer air valve is communicated with the outer-layer air bag.
Furthermore, a connecting channel of the inner air valve and the inner air bag and a connecting channel of the outer air valve and the outer air bag are arranged in the tube wall of the catheter body.
The utility model provides a have unexpected and extract damage-proof type catheter, when taking place unexpected tube drawing, can utilize sharp tooth of inlayer gasbag outer wall and the sharp tooth of outer gasbag inner wall to puncture outer gasbag, inlayer gasbag, the cladding can cover sharp tooth at the protection film of outer gasbag outer wall moreover, consequently can not harm bladder and urethra when unexpected pulling out.
Drawings
FIG. 1 is a schematic view of an embodiment of the present invention showing an atraumatic catheter with accidental pull-out when the balloon is not inflated;
FIG. 2 is a schematic view of the catheter with accidental pull-out atraumatic catheter according to an embodiment of the present invention after balloon inflation;
fig. 3 is a schematic structural view of a balloon in an atraumatic catheter with accidental pull-out according to an embodiment of the invention.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1-3, an intentional outward-pulling anti-injury urinary catheter provided by an embodiment of the present invention includes a soft urinary catheter body 1, wherein an air bag 2 is disposed at the front part of the urinary catheter body;
the number of the air bags is two, wherein one air bag is an inner air bag 23, the other air bag is an outer air bag 22, the inner air bag 23 is positioned in a cavity of the outer air bag 22, the outer wall of the inner air bag 23 is provided with sharp teeth 24 for puncturing the outer air bag, the inner wall of the outer air bag 22 is provided with sharp teeth 25 for puncturing the inner air bag, and the outer wall of the outer air bag is coated with a layer of elastic, breathable and water permeable protective film 21;
the rear part of the catheter body is provided with an inner layer air valve 3 and an outer layer air valve 4, the inner layer air valve 3 is communicated with an inner layer air bag 23, the outer layer air valve 4 is communicated with an outer layer air bag 22, and a connecting channel of the inner layer air valve and the inner layer air bag and a connecting channel of the outer layer air valve and the outer layer air bag are arranged in the tube wall of the catheter body.
The utility model discloses application method as follows:
in the initial state, the inner layer air bag 23 and the outer layer air bag 22 are in a deflated state, and the bag walls of the inner layer air bag 23 and the outer layer air bag 22 are in a loose state and cannot be punctured by the sharp teeth;
after the front end of the catheter body is inserted into the bladder, the outer air bag 22 is inflated (or filled with water) through the outer air valve 4 to expand the catheter body, so that the catheter body is fixed in position and is not easy to drop when being left in the bladder, and the water seepage protective film 21 can also generate certain elastic deformation along with the expansion of the outer air bag 22;
then, the inner air bag 23 is inflated (or filled with water) through the inner air valve 3 to expand, and the inflation (or filling) amount is proper, so that a gap is formed between the sharp teeth 24 on the inner air bag 23 and the bag wall of the outer air bag 22, and a gap is also formed between the sharp teeth 25 on the outer air bag 22 and the bag wall of the inner air bag;
normal tube drawing can be implemented only by discharging air (or water) in the inner air bag and the outer air bag through the inner air valve and the outer air valve;
when accidental forced extubation occurs (for example, a patient forcibly pulls out a catheter), the outer air bag is pressed by the bladder and the body in the urethra to contract inwards, so that the sharp teeth 24 on the inner air bag 23 touch the tightened bag wall of the outer air bag 22, the outer air bag 22 is punctured, meanwhile, the sharp teeth 25 on the outer air bag 22 also touch the bag wall of the inner air bag 23, the inner air bag 23 is also punctured, air (or water) in the two air bags leaks to the outside through the water seepage protective film 21, the two air bags are also deflated, and the water seepage protective film 21 coated on the outer wall of the outer air bag can cover the sharp teeth, so that the bladder and the urethra cannot be damaged when the catheter is accidentally pulled out.
