Abstract
A kind of electronic catheter of anti-clogging for the discharge of urethra clot includes crushing cutting head, driving device, and driving device is connect by the transmission shaft in catheter with cutting head is crushed；The catheter is equipped with negative pressure connector.The advantages of the utility model is invented is, on the basis of traditional catheter, drives crushing cutter tip to carry out cutting crushing to the clot in urine by electric device, and it is excluded by vacuum suction external, blocking of the clot to catheter is prevented, the efficiency of urethral catheterization is improved, mitigates the pain of patient.
Description
Technical field
The utility model invention is related to a kind of catheter, more particularly to a kind of electronic urethral catheterization of anti-clogging for the discharge of urethra clot
Device.
Background technology
Existing catheter generally carries out urethral catheterization drainage by negative pressure, but in actual use often because of the clot in urine
The blocking for causing catheter influences the effect of urethral catheterization, and the pain of body and spirit is caused to patient.
Invention content
In view of the above-mentioned problems, the present utility model is a kind of for urethra clot row the technical problem to be solved is that providing
The electronic catheter of anti-clogging gone out drives spiral cutter head to be crushed the clot in urine, reduces blood by electromechanical device
Blocking of the block to conduit, improves the efficiency of urethral catheterization, mitigates the pain of patient.
To realize technical solution of the present utility model, a kind of electronic catheter of anti-clogging for the discharge of urethra clot
Including crushing cutting head, driving device, driving device is connect by the transmission shaft in catheter with cutting head is crushed；
The catheter is equipped with negative pressure connector.
Further, the crushing cutting head includes metal pipe sleeve, and pipe sleeve front end is circle, and side is provided with into urine hole, interior
There is helical form axis shape bite；It is internally provided with fixed component in the catheter front end, the fixed component includes locating ring, and
It is located at the positioning ring outer wall to connect with urethral catheterization inside pipe wall by retainer plate, two end opening of the retainer plate, inner hollow are described
It is equipped in locating ring and holds axis, transmission shaft is connect by holding axis with cutter head.
Further, transmission outer shaft sleeve sets protection pipe, and protection pipe is more than 1 millimeter at a distance from transmission shaft outer surface.
Further, transmission shaft includes an at least elastomeric element, and two end of elastomeric element respectively sets a rigidity component.
The advantages of the utility model：Driving device drives cutter head rotation by transmission shaft, is broken to endo-urethral clot
It is broken, make clot be easier to be discharged, although setting transmission shaft, cutter head can occupy catheter inner space, in order to ensure the effect of urethral catheterization
Fruit needs to increase the sectional area of catheter, but compared to relatively for the degree that clot is crushed, the increased sectional area of catheter only exists
Within 1 15 to 25, patient will not substantially be influenced too much.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is A-A sectional schematic diagrams in Fig. 1.
Fig. 3 is transmission shaft preferred structure schematic diagram.
In such as figure, catheter 1 crushes cutting head 2, transmission shaft 3, headgear 4, cutter head 5, protection pipe 6, negative pressure connector 7, positioning
Circle 8, elastomeric element 10, rigidity component 11, holds axis 12 at retainer plate 9.
Specific embodiment
In Fig. 1,2, a kind of mechanical conduit for the discharge of urethra clot includes crushing cutting head 2, driving device, driving
Device is connect by the transmission shaft 3 in catheter 1 with cutting head 2 is crushed；
It is additionally provided with negative pressure connector 7 on catheter 1, when work, negative pressure connector 7 can be connected with negative tube, made in place's wall sleeve 1
Full of negative pressure, it is conducive to urination and extracts broken clot out.
Transmission shaft 3 is equipped in catheter 1（Preferably, protection pipe 6 is arranged outside transmission shaft 3, protection pipe is flexible conduit or leads firmly
Pipe, protection pipe 6 are more than 1 millimeter at a distance from 3 outer surface of transmission shaft, when outer wall sleeve 1 is inserted into human body, 1 meeting of outer wall sleeve
By the pressure of human body, so that it deforms, in order to ensure smoothly to urinate, deformation rate cannot be too big, in order to avoid cause outer wall
Sleeve 1 occurs bending and transmission shaft 3 is caused to lose transmission effect, and protection pipe 6 can completely cut off transmission shaft 3 and pass through in outer wall sleeve 1
Urine, to prevent transmission shaft 3 from being polluted by urine, protection pipe 6 is more than 1 millimeter at a distance from 3 outer surface of transmission shaft, with protection pipe 6
Compressive deformation reserves surplus）, it includes headgear 4 with holes to crush cutting head 2, and cutter head 5 is equipped in headgear（Preferably, cutter head 5 is
Spiral cutter head, when installation, cutter head 5 is fitting 4 inner wall of headgear, and cutter head 5 is helicaled feed on one side shred while）, 3 front end of transmission shaft
It is connect with cutter head 5, rear end and driving device（Driving device can be located in outer wall sleeve 1, or be located at outside outer wall sleeve 1,
This structure is similar to electric toothbrush, and small machine as electric toothbrush may be used in driving device）Connection.
Preferably, it is internally provided with fixed component in 1 front end of the catheter, fixed component includes locating ring 8, and is located at institute
It states 8 outer wall of locating ring to connect with 1 inner wall of catheter by four retainer plates 9,9 two end opening of the retainer plate, inner hollow, it is fixed
It is equipped in position circle 8 and holds axis 9, transmission shaft 3 is connect by holding axis 12 with cutter head 5, in use, cutter head 5 is transmitted the driving rotation of axis 3
（Locating ring 8 is supported cutter head 5, transmission shaft 3）, to urine clot into being crushed, the clot being broken later passes through retainer plate 9
It is discharged after in into catheter 1.
Preferably, as in Fig. 3, transmission shaft 3 includes an at least elastomeric element 10, and 10 2 end of elastomeric element respectively sets a steel
Property component 11, an elastomeric element 10 is set on transmission shaft 3, when transmission shaft 3 is by external lateral pressure, 10 meeting of elastomeric element
It deforms, to realize transmission shaft under bowed state, realizes transmission, although above structure can reduce the transmission effect of transmission shaft 3
The density of rate, but extremely adapt to human physiological structure, the intensity and length of elastomeric element 10, and setting, is the technology of enterprise
Secret is described in detail herein, i.e., general technical staff and existing technology are can to produce the biography of this patent introduction
Moving axis and other structures can be because of small differences only in service life and operability, and there are prodigious differences.
