The invention discloses the catheter joint of a kind of counterflow-preventing, relating to medical sanitary apparatus apparatus field, including connecting tube and step-like catheter, described catheter includes body section and linkage section, the diameter of linkage section is more than the diameter of body section, and offers bayonet socket on the inner surface of linkage section；Being provided with conical seat in described linkage section, be provided with the passage communicated with connecting tube in conical seat, and connecting tube is plugged between conical seat and linkage section, the inserted terminal of connecting tube is clamped in bayonet socket；Being additionally provided with retainer ring and taper plug in described connecting tube, the tip of taper plug pushes against with conical seat, and is provided with compression spring between taper plug and retainer ring.The present invention can make connecting tube be clamped in catheter, effectively prevents connecting tube from coming off with catheter, can be prevented effectively from the leakage of urine simultaneously, be connected firmly；And the urine being also avoided that in Bag for collecting urine is back in catheter by connecting tube, prevent patient's superinfection.
Description
Technical field
The present invention relates to medical sanitary apparatus apparatus field, in particular to the catheter joint of a kind of counterflow-preventing.
Background technology
Bladder irrigation is the high requisite basic nursing skills of nursing of frequency that diseases of urinary system patient does, and urethral catheterization
Pipe cannot be connected tight with the connecting tube of Bag for collecting urine, easily come off, after coming off urine directly from catheter outflow, cause sheet or
Clothing contamination.The thing followed be change clothes sheet quilt cover, packing paper diaper increases nursing work load, improve medical treatment and nursing become
This, be the long-term unsolved puzzlement of numerous health care workers.Simultaneously when patient does not notes, the urine in Bag for collecting urine is easy to
It is back in catheter, causes patient's superinfection.
Summary of the invention
It is an object of the invention to provide the 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 catheter joint of a kind of counterflow-preventing, including connecting tube and
Step-like catheter, described catheter includes body section and linkage section, and the diameter of linkage section is more than the diameter of body section, and connects
Bayonet socket is offered on the inner surface of the section of connecing；It is provided with conical seat in described linkage section, is provided with in conical seat and communicates with connecting tube
Passage, and connecting tube is plugged between conical seat and linkage section, the inserted terminal of connecting tube is clamped in bayonet socket；In described connecting tube
Being additionally provided with retainer ring and taper plug, the tip of taper plug pushes against with conical seat, and sets between taper plug and retainer ring
It is equipped with compression spring.
Further, the inserted terminal of described connecting tube is provided with multiple radial expansible wings, and adjacent two expansible wings it
Between be provided with opening.
Further, described expansible wings is at least 3.
The invention has the beneficial effects as follows, the present invention can make connecting tube be clamped in catheter, effectively prevents connecting tube and leads
Urinary catheter comes off, and can be prevented effectively from the leakage of urine, and simple in construction simultaneously, be connected firmly, and the present invention is prevented effectively from chamber pot simultaneously
Urine in Dai is back in catheter by connecting tube, prevents patient's superinfection.

Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The catheter joint of a kind of counterflow-preventing that the present invention that Fig. 1, Fig. 2 are shown provides, including connecting tube 6 and step-like
Catheter 1, and catheter 1 outer surface and inner surface are all in ledge structure, and described catheter 1 includes body section 2 and linkage section
3, the diameter of linkage section 3 is more than the diameter of body section 2, and linkage section 3 is connected with connecting tube 6, and offers on the inner surface of linkage section 3
Having bayonet socket 4, the cross section of bayonet socket 4 is triangle；It is provided with conical seat 5 in described linkage section 3, is provided with in conical seat 5 and connecting tube 6
The passage 9 communicated, the gradient on conical seat 5 surface is consistent with the gradient on bayonet socket 4 inclined-plane, and the surface of conical seat 5 and bayonet socket
4 between gap equal to the wall thickness of connecting tube 6, connecting tube 6 is plugged between conical seat 5 and linkage section 3, and passage 9 is logical for taper
Road, the flow direction that passage 9 is flowed into connecting tube 6 along catheter 1 tapers into, and the inserted terminal of connecting tube 6 is clamped on bayonet socket 4
In, make the tapered shape of inserted terminal of connecting tube 6；Retainer ring 10 and taper plug 11, retainer ring it is additionally provided with in described connecting tube 6
10 are fixedly mounted in connecting tube 6, and the outer surface of retainer ring 10 coordinates with the inner surface of connecting tube 6, the tip of taper plug 11
Pushing against with conical seat 5, the tip of taper plug 11 is positioned at the passage 9 of conical seat 5, makes conical seat 5 relative with taper plug 11
Arrangement, less than the internal diameter of connecting tube 6 at the maximum gauge of taper plug 11, and is provided with between taper plug 11 and retainer ring 10
Compression spring 12.
The inserted terminal of described connecting tube 6 is provided with between multiple radial expansible wings 7, and adjacent two expansible wings 7 setting
There is opening 8, make the inserted terminal of connecting tube 6 can independently open when grafting and be clamped in bayonet socket 4.Described expansible wings 7 at least 3
Individual, distribution is more uniform, and the effect of clamping is more preferable.
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.
