Abstract
A triple cavity indwelling catheter relates a medical appliance which is used to induce urine when the urine is retention during the case watching for the patient after operation or in the operation. The catheter comprises an elliptical side opening which is communicated with the central cavity from the top end, an air-pocket, a tunnel which is communicated with the side opening in the air-pocket, five strip tunnels with connecting a plurality of small side openings on the pipe wall, a rear end with one-way valve which is in relative to the five trip tunnels and a bottom end which is communicated with the central cavity of the ureter. The utility model possesses functions of convenience, health, small stimulation for urethra stick film and light harm with non-invasive.
Description
Affiliated technical field
This utility model relates to a kind of medical equipment, is drainage of urine when being used for patient's urine retention, or in the art, the clinical follow state of an illness and washed bladder.Particularly need long-time patients with indwelling, easily sterilization, easily change urinary catheter, to patient's mucous membrane of urethra stimulate little, damage is light.
Background technology
At present the catheter that uses is divided into two kinds of General Purpose Rubber catheter and FoleyShi catheters (Foley catheter).When ordinary urethral catheter is made indwelling catheter, need use immobilization with adhesive tape, the male will stick at catheter and penis both sides with butterfly type adhesive plaster, again with the loose DNA releaxed circular DNA of another adhesive plaster around penis, with fixing butterfly type adhesive plaster, the adhesive plaster narrow end is fixed on the catheter.Around adhesive tape be sure not around tension, with the blood circulation of obstruction free penis.The women can use Hengshan Mountain font adhesive plaster, and roomy partial fixing is on mons pubes, and middle billet is around pasting catheter, and two is rectangular respectively around one week of catheter, is fixed in perineal position and two thighs again.After adhesive plaster was flooded by urine, viscosity faded away, and catheter comes off easily, and simultaneously, some patient can cause scytitis to cloth hypersensitivity.Though trouble and shortcoming that the FoleyShi catheter need not above-mentioned processing are put catheter, when extracting urinary catheter, and after urinary catheter extracts, because that urinary catheter stimulates urethral mucosa is heavier, urine retention takes place in patient's sharp ache again, and patient is caused very big misery.
Summary of the invention
The purpose of this utility model has solved existing catheter stimulates heavier problem to urethral mucosa.This utility model no matter during urethral catheterization or urinary catheter extract moment, patient's urethral mucosa is not had the tearing damage.
This technical scheme of using novel technical solution problem to be adopted is: go into a plurality of small side holes of five tunnels by tube wall and communicate with the catheter outside in that the urethral catheterization tube wall is built-in, inject paraffin oil through this during use, paraffin oil evenly is applied to the urinary catheter outer wall by small side hole, when inserting or withdrawal process, make and occur between catheter and urethral mucosa isolating, littler to the urethral mucosa stimulation, nothing is rushed or the purpose of Wicresoft thereby reach.
The beneficial effects of the utility model are: use safer, convenient, healthy, easy disposal, easy making simple in structure.The misery that causes to patient in operating process is littler.
Description of drawings
Below in conjunction with accompanying drawing and enforcement this utility model is further specified.
Fig. 1 is the novel structural representation of this use (topography)
Fig. 2 is the novel cross-sectional view of this use (indwelling catheter stage casing, three chambeies)
1. tops among the figure, 2. oval side opening, 3. air bag, 4. air bag inboard aperture, 5. tube wall small side hole, 6. through air bag tunnel, 7. many small side hole tunnels, 8. catheter center cavity, the 9. tail end (band check valve) in through air bag tunnel, 10. the tail end (band check valve) after five tunnels merge, 11. catheter center cavity tail ends.
The specific embodiment
Urinary catheter always is about 40～50cm, external diameter 0.6cm, internal diameter 0.2cm, thickness of pipe wall 0.2cm, in six tunnel diameter 0.05～0.08cm are arranged, wherein five along tube wall week footpath uniform distribution, another are between above-mentioned two, air bag is apart from the about 1.5～3.5cm of near-end, about 18～20 milliliters of its capacity, every tunnel small side hole spacing 0.5cm, small side hole diameter 0.03cm, article five, the tail end of tunnel fusion and the tail end in through air bag tunnel are equipped with one-way cock, and its diameter is identical with the ordinary syringe top, the about 1.0cm of catheter rear diameter chap.
It is circular that top (1) is point, there is oval-shaped side opening (2) both sides, air bag (3), there is a side opening (4) the air bag inboard, tube wall has a large amount of small side hole (5), there is center cavity (8) in catheter central authorities, the tunnel (6) that a through air bag is arranged, and tail end band check valve (9), article five, the tunnel that communicates with small side hole (7), and merge the back with end and form band check valve tail end (10), with through the oval-shaped side opening in both sides, top by catheter center cavity and the terminal tail end (11) that forms, apart from top 0.5～0.8cm the about 0.2 * 0.5cm of corresponding two oval side openings (2) is arranged, six tunnels are arranged in the urethral catheterization tube wall, wherein one by the through air bag (6) of tail end, five tunnels are by the through air bag far-end (7) of tail end in addition, and to catheter tail end 4.5cm, male's catheter has many small side holes from air bag far-end 0.03cm to the female patients catheter between catheter tail end 16cm from air bag far-end 0.03cm.
Inject aseptic paraffin oil through (10) during use, paraffin oil evenly is applied to the catheter outer wall through (7) by (5).No matter put urinary catheter or pull out the urinary catheter process, because paraffin oil makes between urethral catheterization tube wall and urethral mucosa and sealing coat occurs, reducing catheter stimulates and mucosa injury urethral mucosa.Inject 18～20 milliliters of physiological saline solution through (9), to (3), make (3) expand fixation, prevent that catheter from coming off by (6), (4).When catheter was inserted bladder, urine was passed through (8), (11) to drainage device through (2).
Claims (3)
