Description

Indwelling catheter connector

The technical field is as follows:

the utility model relates to a medical treatment auxiliary device especially relates to an keep somewhere type catheter connector.

Background art:

the indwelling catheter is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), can be inserted into the bladder through the urethra to drain urine, and after the indwelling catheter is inserted into the bladder, an air bag is arranged at the end close to the catheter end to fix the catheter to stay in the bladder, so that the urine in the bladder is discharged and is connected with the urinary catheter bag during urination. Indwelling catheters are typically used for 1-2 weeks and replaced during which time the urinary bag to which the catheter is attached must be replaced frequently. The catheterization bag that uses often at present is connected through the rubber tube that has the drainage head of annular step and catheter export, and the connector is more difficult to extract behind the rubber tube, need turn over when changing the urine bag and roll over and pull and just can take off, leaks the urine easily at this in-process and causes the pollution.

The utility model has the following contents:

the utility model discloses on aiming at not changing the basis of the connection position structure of current catheter and catheterization bag, provide one kind can be easy to assemble and take off keep somewhere type catheterization pipe connector, the leakproofness is good, pulls out the difficult urine that leaks that produces of in-process, and its technical scheme is as follows:

the utility model provides an keep somewhere type catheter connector, including the connecting pipe, sleeve pipe and fixation clamp, the fixation clamp passes through connecting band and sleeve pipe external connection, be equipped with the arc recess on the connecting pipe, the fixation clamp comprises a pair of clamp and wind spring, the oral area of clamp be equipped with connecting pipe arc recess matched with arc protruding, and the oral area of clamp diameter when the clamp is in clamping state is the same with the connecting pipe diameter, intraductal baffle and the guiding tube of being equipped with of cover, be equipped with the opening on the baffle, the guiding tube inner circle is equipped with elastic sealing ring, the sleeve pipe outside is equipped with the non-. When the fixing clamp is used, the rubber tube at the outlet of the catheter is sleeved on the connecting tube, and the arc-shaped bulge of the jaw part of the fixing clamp is aligned with the arc-shaped groove on the connecting tube and clamps the fixing clamp. The drainage head at the inlet of the urine bag is inserted into the guide tube, and the drainage head is clamped and sealed by the elastic sealing ring and cannot be pulled out under the action of the check hook.

Furthermore, the middle part of the baffle is arc-shaped and is matched with the drainage head at the inlet of the urine bag, so that the sealing effect of the drainage head after being inserted into the guide tube is improved.

Furthermore, the connecting band is elastic connecting band, makes the fixation clamp operation more convenient.

Compared with the prior art, the utility model discloses the beneficial effect who produces is: can connect and keep somewhere type catheter and catheterization bag on the basis that does not change the connection position structure of current catheter and catheterization bag, easy to assemble with take off, the leakproofness is good, pulls out the difficult urine that leaks that produces of in-process.

Description of the drawings:

in order to more clearly illustrate the technical solution in the embodiments of the present invention, the drawings required to be used in the embodiments will be briefly described below.

FIG. 1 is a schematic cross-sectional view of an indwelling catheter connector according to an embodiment of the present invention in an uninstalled state;

FIG. 2 is a schematic cross-sectional view of an indwelling catheter connector according to an embodiment of the present invention in place;

in the figure:

1. a connecting pipe; 2. a sleeve; 3. a fixing clip; 31. clamping; 32. an arc-shaped bulge; 33. a coil spring; 34. a mouth; 4. an arc-shaped groove; 5. a baffle plate; 6. a guide tube; 7. an elastic sealing ring; 8. a non-return hook; 9. an opening; 10. a connecting belt; 11. a drainage head; 12. rubber tube

The specific implementation mode is as follows:

the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model provides a keep somewhere type catheter connector, including connecting pipe 1, sleeve pipe 2 and fixation clamp 3, fixation clamp 3 passes through connecting

band

10 and 2 external connections of sleeve pipe, be equipped with arc recess 4 on the connecting pipe 1, fixation clamp 3 comprises a pair of clamp 31 and wind spring 33, the oral area 34 of clamp 31 is equipped with the arc arch 32 with arc recess 4 matched with, and the oral area 34 of clamp 31 diameter is the same with 1 diameter of connecting pipe when clamp 31 is in clamping state, be equipped with baffle 5 and guiding tube 6 in the sleeve pipe 2, be equipped with opening 9 on the baffle 5, guiding tube 6 inner circle is equipped with elastic sealing ring 7, the sleeve pipe 2 outside is equipped with non-return pothook 8 with guiding tube 6 junction.

Preferably, the middle part of the baffle 5 is arc-shaped and is matched with the drainage head 11 at the inlet of the urine bag, so that the sealing effect of the drainage head 11 after being inserted into the guide tube 6 is improved.
