Abstract
The utility model discloses a disposable medical catheter and a matched drainage bag. A urine guiding-out hole of a urine guiding pipe is a hard structure, has a fixed size and is provided with screw on the surface. A drainage connector of the drainage bag comprises a nipple and a screw cap. When the urine guiding pipe is connected with the drainage bag, the urine guiding hole is connected with the drainage connector, and screwing the screw cap is required. When a double-chamber urine guiding pipe is used for irrigating the bladder, the urine guiding-out hole is connected with a medial three-way valve. One side of the three-way valve is connected with a transfusion pipe, and the other side is connected with the drainage bag. The flowing direction of the liquid is adjusted through the three-way valve for irrigating the bladder. A liquid medicine injection opening is directly connected with the transfusion pipe when a three-chamber urine guiding pipe is used for irrigating the bladder. The urine guiding pipe of the utility model can be fixedly connected with the drainage bag so that the drainage bag does not fall off and the nursing load is reduced. The connector between the urine guiding pipe and the drainage bag is provided with a screw cap for covering so that the retrograde infection probability of the urinary system is reduced. The disposable medical catheter has the advantages of convenient using and suitability for being widely used for clinical catheter indwelling and bladder irrigating.
Description
Technical field
This utility model relates to o urethral catheterization device, relate in particular to can fixedly connected drainage bag Dispoable medical catheter and supporting drainage bag.
Background technology
Existing catheter comprises three types: single chamber catheter, double lumen catheter and three-cavity catheter.Earlier catheter is inserted bladder during urethral catheterization, again the flow sub socket of the urine export mouth of catheter and drainage bag.Because the urine export mouth is flexible, size is fixing, and is insecure with being connected of the flow sub of drainage bag, comes off easily, causes the urine outflow, increases the nursing burden; Interface when catheter is connected with drainage bag is exposed to the outside, causes the urinary system retrograde infection easily, causes medical expense to increase; Catheter connects the tube for transfusion inconvenience, need be equipped with the bladder irrigation bag during bladder irrigation and could wash the process complexity.
Summary of the invention
The purpose of this utility model is: at the above-mentioned defective of prior art, providing can fixedly connected drainage bag and be convenient to the Dispoable medical catheter and the supporting drainage bag of bladder irrigation.
The purpose of this utility model realizes by following scheme: the urine export mouth of catheter is a solid structure, and size is fixing, and there is screw thread on the surface; The flow sub of drainage bag comprises nipple, screw-cap.
The size of urine export mouth is identical with the pintle of syringe needle, matches with the nipple of drainage bag; There is screw thread on urine export mouth surface.The design of the medicinal liquid inlet of three-cavity catheter is identical with the urine export mouth.
The good size and spaced farapart of drainage bag is identical with the tube for transfusion nipple; The screw thread on screw-cap female thread and urine export mouth surface matches; The screw-cap sidewall laterally forms the adjusting stricture of vagina of being convenient to operate.
The fixedly connected drainage bag of this utility model catheter energy, drainage bag can not come off, and reduces the nursing burden; The seam that catheter is connected with drainage bag has screw-cap to cover, and reduces the probability of urinary system retrograde infection.Catheter and tube for transfusion are easy to connect, help bladder irrigation.The design is simple in structure, and is easy to use, is widely used in clinical indwelling catheter and bladder irrigation.
Description of drawings
This utility model provides three types of catheters and supporting drainage bag.
Fig. 1 is single chamber catheter example structure sketch map.
Fig. 2 is a double lumen catheter example structure sketch map.
Fig. 3 is a three-cavity catheter example structure sketch map.
Fig. 4 is a drainage bag example structure sketch map.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility model is elaborated.
Fig. 1 is single chamber catheter, comprises urine introducing port 1, single lumen catheter 3 and urine export mouth 2, during urethral catheterization catheter inserted bladder after, urine export mouth 2 is connected drainage bag flow subs 9, screw screw-cap 9 (b) and get final product.
Fig. 2 is a double lumen catheter, include urine introducing port 1, air bag 4, double channel catheter 3, urine export mouth 2, air bag injection valve 5 formations, after during urethral catheterization catheter being inserted bladder, heave air bag 4 by air bag injection valve 5 suitable liquid of injection or gas, urine export mouth 2 is connected drainage bag flow sub 9, screw screw-cap 9 (b) and get final product.Connect medical three-way valve at urine export mouth 2 during the row bladder irrigation, a side joint tube for transfusion of three-way valve, a side joint drainage bag is regulated the flow direction of liquid and is carried out bladder irrigation by three-way valve.
Fig. 3 is a three-cavity catheter, includes urine introducing port 1, medicine liquid outlet 6, air bag 4, three cavities conduit pipe 3, air bag injection valve 5, urine export mouth 2, medicinal liquid inlet 7 and 8 formations of blocking a shot, and medicinal liquid inlet 7 usefulness block 8 is not built when not carrying out bladder irrigation at ordinary times.Three-cavity catheter is inserted bladder and is reached the fixedly same double lumen catheter of drainage bag method, takes off the block 8 of medicinal liquid inlet during bladder irrigation, tube for transfusion is connected medicinal liquid inlet 7 can carry out bladder irrigation.
Fig. 4 is a drainage bag, comprise flow sub 9, drainage tube 10, suspension strap 11, Liquid storage bag 12,, discharging tube 13 and tapping valve 14, flow sub comprises nipple 9 (a), screw-cap 9 (b).Elder generation packages the nipple 9 (a) and the urine export mouth 2 of flow sub during urine drainage, and the thread surface by urine export mouth 2 screws screw-cap 9 (b) again, thereby fixedly connected.
Novel Dispoable medical catheter that provides and supporting drainage bag are provided for this, can pack separately, also can be placed in the disposable sterilized urethral catheterization bag.Single chamber catheter caliber is little, is suitable for prostate hyperplasia, with the patient of traditional urethral catheterization method intubation defeat, or child's urethral catheterization usefulness; Double lumen catheter is suitable for perform the operation preceding, postoperative patient, and the patient who needs indwelling catheter; Three-cavity catheter also is suitable for perform the operation preceding, postoperative patient, and the patient who needs indwelling catheter, because the medicinal liquid inlet that can directly connect tube for transfusion is arranged, bladder irrigation is more convenient.
