Abstract
This utility model belongs to medical instruments field, be specially a kind of three-cavity catheter with sealing joint, comprise chamber of urinating, water-injecting cavity and rinse chamber, it is characterized in that arranging sealing joint at flushing end, described sealing joint is made up of shell, puncture conduit and silicon cover: shell is open column shape structure, is installed on and rinses end outside; Be fixed on bottom puncture conduit to rinse in end and hold with flushing and be communicated with, top becomes coniform and has 3 transverse side holes; Compressible silicon cover is placed between shell and puncture conduit.Without the need to using syringe needle when this apparatus is done, the requirement of bladder irrigation flow velocity can be met, avoiding medical personnel to be stabbed by syringe needle simultaneously; Utilize malleation principle, urine can not be backflowed, make bladder irrigation device completely airtight, not easily pollute, can not slippage, reduce the incidence rate of urinary tract infection, the requirement of rigorous aseptic technology can be reached; The price of bladder irrigator is partially expensive, and sealing joint can directly be connected with transfusion device or blood exchange transfusion set, reduces developing cost.
Description
Technical field
This utility model belongs to medical instruments field, is specially a kind of three-cavity catheter with sealing joint.
Background technology
Three-cavity catheter is a kind of pipeline, can through per urethram inserting bladder in case drainage of urine out.In existing medical system, three-cavity catheter can also be used for the work of bladder irrigation and intravesical administration while indwelling catheter.
The operation principle of three-cavity catheter is utilize the pressure of bladder that urine chamber of passing through to urinate is excreted; Sacculus can swell after by water-injecting cavity water filling and block bladder, is used for fixing catheter when indwelling catheter; Rinse chamber to be used for rinsing or intravesical administration, it is unlimited for rinsing end, and be directly connected with irrigator when carrying out bladder irrigation, the used time does not just block up.Have document to mention to rinse to hold with calparine cap and urinary catheter and be connected, during flushing, the syringe needle of transfusion device thrusts calparine cap; But when three chamber urinary catheters are used for urologic neoplasms patient, particularly block catheter patient with easily there is clot during hematuria, this just has requirement to the flow velocity rinsed, and the flow velocity of syringe needle is crossed and can not well be prevented catheter to block slowly; In addition, it is also not exclusively airtight with the connection of calparine cap that urinary catheter rinses end, and have the possibility of deviating from, patient exists the risk of latent infection.
Summary of the invention
Rinse end design Problems existing for existing three-cavity catheter, this utility model provides a kind of three-cavity catheter with sealing joint.
A kind of three-cavity catheter with sealing joint of the present utility model, comprise chamber of urinating, water-injecting cavity and rinse chamber, it is characterized in that arranging sealing joint at flushing end, described sealing joint is made up of shell, puncture conduit and silicon cover: shell is open column shape structure, is installed on and rinses end outside; Be fixed on bottom puncture conduit to rinse in end and hold with flushing and be communicated with, top becomes coniform and has 3 transverse side holes; Compressible silicon cover is placed between shell and puncture conduit.
During use, insert in shell by the mastoid process front end of sealing joint and syringe or transfusion device, silicon cover receives extruding compression, and fluid injects in the side opening of puncture conduit from syringe, thus enters bladder via the flushing chamber of three-cavity catheter, completes flushing or administration.Silicon cover inside is in aseptic condition all the time, and surface can cleaning disinfection.
As preferably, described silicon cover is formed by connecting for several O type silicon rings, ensures the elasticity that silicon overlaps to keep the memory of closed system after injection.Described cover top portion is equipped with fluorescent ring, to facilitate medical personnel in the operation at night.
A kind of three-cavity catheter with sealing joint of the present utility model, without the need to using syringe needle during operation, can meet the requirement of bladder irrigation flow velocity, avoiding medical personnel to be stabbed by syringe needle simultaneously; Utilize malleation principle, urine can not be backflowed, make bladder irrigation device completely airtight, not easily pollute, can not slippage, reduce the incidence rate of urinary tract infection, the requirement of rigorous aseptic technology can be reached; The price of bladder irrigator is partially expensive, and sealing joint can directly be connected with transfusion device or blood exchange transfusion set, reduces developing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of sealing joint of the present utility model;
Wherein, three-cavity catheter 1, sealing joint 2, rinses end 1-1, shell 2-1, puncture conduit 2-2, side opening 2-3.
Detailed description of the invention
Embodiment 1: a kind of three-cavity catheter with sealing joint of the present utility model, comprise chamber of urinating, water-injecting cavity and rinse chamber, it is characterized in that arranging sealing joint at flushing end 1-1, described sealing joint is made up of shell 2-1, puncture conduit 2-2 and silicon cover: shell 2-1 is open column shape structure, is installed on and rinses outside end 1-1; Be fixed on bottom puncture conduit 2-2 and rinse in end 1-1 and hold 1-1 to be communicated with flushing, top becomes coniform and has 3 transverse side holes 2-3; Compressible silicon cover is placed between shell 2-1 and puncture conduit 2-2.Described silicon cover is formed by connecting for several O type silicon rings, ensures the elasticity of silicon cover, keeps the memory of closed system after injection.Described shell 2-1 top is equipped with fluorescent ring, to facilitate medical personnel in the operation at night.
