Description
Technical field
The utility model is related to field of medical device, especially a kind of triplet type catheter.
Background technology
Modern times are in the medical means of urinary tract dredging treatment, catheter is one of essential tool.Present urethral catheterization
When pipe is used for cleaning urinary tract, all it is that catheter is first inserted into urinary tract, then injection needle is inserted into catheter, passes through syringe needle
Brine is convergeed in catheter, urinary tract is finally transported to and is cleaned, but the mode that this syringe needle is inserted into, it is easy to because
External touches and syringe needle is caused to fall off, and the syringe needle that thus must more renew reinserts to be injected again, time-consuming and laborious.
Utility model content
The technical problems to be solved in the utility model is：In order to solve the low deficiency of existing display screen detection efficiency, this
Utility model provides a kind of triplet type catheter, connects Brine Pipe and water pipe by threeway, and to the clamping of Brine Pipe
To prevent its falling off with threeway.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of triplet type catheter, including threeway, conduit, sealing plate, elastomeric element, sleeve, mandril and rubber ring, threeway
Bonding connection has conduit, the lower opening between two opposed opens of threeway to be fixedly connected with to two opposite openings respectively
Sleeve is equipped with the mandril of L-type in sleeve, and bonding connection has rubber ring in sleeve, passes through elastomeric element and sealing plate phase in threeway
Even, the opening that sealing plate is connected with sleeve matches.
Specifically, the elastomeric element is preferably spring strut.
Specifically, the side bonding connection that the sealing plate fits with threeway opening has the sealing ring of rubber system.
Specifically, the sleeve lining is equipped with screw thread, and the threeway opening outer wall being connected with sleeve is equipped with screw thread, set
Cylinder is connect with threeway open-top screw thread.
Specifically, the end face of the sealing plate is equipped with draw ring.
The utility model has the beneficial effects that：The utility model provides a kind of triplet type catheter, is connected by threeway
Brine Pipe and water pipe, and its falling off with threeway is prevented to the clamping of Brine Pipe.

Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Fig. 1 is the structural schematic diagram of the utility model, and Fig. 2 is the upward view of the sleeve of the utility model, and Fig. 3 is this practicality
Novel state diagram when removing sleeve.
A kind of triplet type catheter, including threeway 1, conduit 2, sealing plate 3, elastomeric element 4, sleeve 5, mandril 6 and rubber
Ring 7, bonding connection has conduit 2, the under shed between two opposed opens of threeway 1 to 1 two opposite openings of threeway respectively
Place is fixedly connected with sleeve 5, and the mandril 6 of L-type is equipped in sleeve 5, and bonding connection has rubber ring 7 in sleeve 5, passes through in threeway 1
Elastomeric element 4 is connected with sealing plate 3, and the opening that sealing plate 3 is connected with sleeve 5 matches.The elastomeric element 4 is preferably spring
Cylinder.The side bonding connection that the sealing plate 3 fits with the opening of threeway 1 has the sealing ring 8 of rubber system.5 inner wall of the sleeve
It is equipped with screw thread, the threeway 1 being connected with sleeve 5 is open outer wall equipped with screw thread, and sleeve 5 is connect with 1 open-top screw thread of threeway.Institute
The end face for stating sealing plate 3 is equipped with draw ring 9.
When this catheter does not have connector sleeve sleeve 5, when being only used as two siphunculus road urethra being dredged or rinsed, sealing plate
3 are fully mated with 1 opening of threeway and seal, and threeway at this time 1 is equipped with externally threaded opening and just seals completely, only remaining
Two opposite open communications（As shown in Fig. 3）, threeway at this time 1 only used as single pipeline.And 3 edge of sealing plate
The sealing ring 8 at place can increase the leakproofness between sealing plate 3 and threeway 1, prevent liquid from the connection of sealing plate 3 and threeway 1
Place's leakage.
When needing using external brine, sleeve 5 is threadedly coupled to threeway 1 first and is equipped with externally threaded opening,
Due to being equipped with the mandril 6 of L-type in sleeve 5, so when constantly rotation is screwed into the opening of threeway 1 to sleeve 5, internal mandril
6 can also follow sleeve 5 constantly to extend toward the direction of threeway 1, the sealing plate 3 in 6 open-top threeway 1 of mandril so that sealing
Plate 3 is detached from from 1 opening of threeway, and the opening that such threeway 1 is sealed just completes unlatching.Then Brine Pipe is opened from sleeve 5
7 through hole of rubber ring at mouthful place penetrates, until Brine Pipe by the opening of sleeve 5 and threeway 1 and is extend into inside threeway 1,
Since the through-hole diameter of rubber ring 7 is more smaller than brine pipe diameter, so when Brine Pipe fills in the through-hole of rubber ring 7, rubber is utilized
The rubber telescopic nature of rubber ring 7 brings it about expansion, and reaction force when replying deformation using it and salt can be clamped
Water pipe, but since 7 through-hole diameter of rubber ring is not more much smaller than rubber ring 7, so the extruding of 7 through-hole of rubber ring will not occur
Power is excessive and the case where blocking Brine Pipe.Brine Pipe can be passed into physiological saline in threeway 1 in this way.Due to Brine Pipe quilt
The delivery outlet of the partial distance Brine Pipe of clamping farther out, stays in so having quite a few Brine Pipe in sleeve 5 and threeway 1,
It is not only able to prevent fluid seepage using rubber ring 7 in this way, additionally it is possible to prevent Brine Pipe from undesirably falling off from threeway 1, increase
Durability.
When needing to restore bilateral state, Brine Pipe is just extracted, 5 spiral of sleeve is back-outed, due to the branch departing from mandril 6
Support, sealing plate 3 is filled out again under the suppressing of spring strut returns to 1 opening of threeway, is finally caught on draw ring 9 again and is pulled outward one with hooking to clamp
Under, it will be able to allow sealing plate 3 and 1 opening of threeway complete gluing, sealing again.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right
Property range.
