Description
Technical field
The present invention relates to a kind of medical instruments, in particular to the three way type catheter joint of a kind of counterflow-preventing.
Background technology
At present, to operation after Urology Department patient care time, owing to patient is handicapped, so needing to pass through urethral catheterization
Urine in patient body is discharged by pipe, but doctor can be sampled inspection every day to the urine of patient in whole therapeutic process
Surveying, therefore doctor is typically all and is directly sampled in urinal, and such sampling mode has the following disadvantages；1, urine
Urine in Dai is not that patient just gets rid of, and the urine placed for a long time exists rotten situation, therefore influences whether inspection
Come to an end fruit；2, when with test tube extraction urine sample, first urine can be with air Long contact time, thus can be by the disease in air
Bacterium is polluted, thus affects inspection result, is then easily dropped on the ground in sampling process urine exactly, pollutes the ring in ward
Border, during censorship, urine easily spills the most exactly；3, when patient does not notes, the urine in urinal is easy to be back to
In catheter, cause the superinfection of patient.
Summary of the invention
It is an object of the invention to provide the three way type catheter joint of a kind of counterflow-preventing, to solve the problems referred to above.
For realizing the object of the invention, the technical scheme of employing is: the three way type catheter joint of a kind of counterflow-preventing, including T
The joint body of type, described joint body is respectively arranged with catheter interface, Bag for collecting urine interface and sample connection；Described urethral catheterization
Interface tube streamwise becomes larger, and is provided with retainer ring and ball in catheter interface, and ball is positioned at catheter and connects
The entrance side of mouth, and between ball and retainer ring, it is provided with compression spring；It is provided with fiber crops on the outer surface of described catheter interface
Stricture of vagina；Being additionally provided with the plug-in unit of activity on described joint body, and the end of plug-in unit is positioned at sample connection, the top of plug-in unit runs through
Joint body is to outward；The through hole of connection catheter interface and Bag for collecting urine interface is offered on described plug-in unit；The end of described plug-in unit
It is provided with the breach of an inclination, and breach is positioned at catheter interface side.
Further, it is equipped with rubber block at described sample connection.
Further, described plug-in unit is provided with sealing device with the through part of joint body.
The invention has the beneficial effects as follows, present configuration is simple, easy to operate, and sampling operation is convenient, and sealing property
Good, effectively prevent the seepage of urine；Urine reflux back in the present invention can effectively prevent catheter simultaneously, in catheter, uses more
Add safety, be prevented effectively from the superinfection of patient.
Accompanying drawing explanation
Fig. 1 is the structure chart of the three way type catheter joint of the counterflow-preventing that the present invention provides；
Labelling and corresponding parts title in accompanying drawing:
1, joint body, 2, catheter interface, 3, sample connection, 4, Bag for collecting urine interface, 5, plug-in unit, 6, through hole, 7, breach, 8,
Retainer ring, 9, ball, 10, compression spring.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The three way type catheter joint of a kind of counterflow-preventing that the present invention that Fig. 1 is shown provides, including T-shaped joint body
1, described joint body 1 is respectively arranged with catheter interface 2, Bag for collecting urine interface 4 and sample connection 3, and urethral catheterization interface 2 with connect
Urinal interface 4 is located along the same line；Described catheter interface 2 streamwise becomes larger, and arranges in catheter interface 2
Having retainer ring 8 and ball 9, retainer ring 8 is fixed on the inwall of catheter interface 2, and ball 9 is positioned at the entrance of catheter interface 2
Compression spring 10 it is provided with between side, and ball 9 and retainer ring 8；Fiber crops stricture of vagina it is provided with on the outer surface of described catheter interface 2；
Being additionally provided with the plug-in unit 5 of activity on described joint body 1, and the end of plug-in unit 5 is positioned at sample connection 3, the top of plug-in unit 5 passes through
Wear joint body 1 to outward；The through hole 6 of connection catheter interface 2 and Bag for collecting urine interface 4 is offered on described plug-in unit 5；Described plug-in unit
The end of 5 is provided with the breach 7 of an inclination, and breach 7 is positioned at catheter interface 2 side.It is equipped with rubber at described sample connection 3
Block, block is mated with sample connection 3.Described plug-in unit 5 is provided with sealing device with the through part of joint body 1.
When plug-in unit 5 inserts in sample connection 3, when through hole 6 on plug-in unit 5 and breach 7 are respectively positioned in sample connection 3, this
Time sample connection 3 and Bag for collecting urine interface 4 be blocking shape, now urine can not be flowed by sample connection 3 and Bag for collecting urine interface 4
Go out；When plug-in unit 5 is centrally located, the breach 7 on plug-in unit 5 is positioned at sample connection 3, and catheter interface 2 connects with Bag for collecting urine
When mouth 4 is connected by through hole 6, urine is entered in Bag for collecting urine by Bag for collecting urine interface 4, and sample connection 3 blocks；When plug-in unit 5
When extracting, Bag for collecting urine interface 4 is in blocked state, and catheter interface 2 is connected with sample connection 3 by breach 7, now can be direct
By being sampled at sample connection 3.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
