Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to figs. 1 to known to Fig. 5: a kind of anti-disposable Micropump extension tube of fold-type, including connector 1, the right end of the connector 1
It is fixedly connected with outer tube 2, integrally connected on the outside of the left end of the outer tube 2 and the bead of 1 right end of connector, the right end peace of the outer tube 2
Inner tube 3 is filled, the right end port inner bulge of the right end integrally connected conduit 4 of said inner tube 3, the connector 1 forms limited ring dais
5, activity installation connecting element 6 at the limited ring dais 5, left section of tube body of said inner tube 3 reduces radius and forms inner catheter 7, described
Inner catheter 7 is inserted into outer tube 2, and the right end of inner catheter 7 is fixedly connected with connector 6.
The outer tube 2 is transparent modeling pipe, and the body interior of outer tube 2 installs spring 8, is bent and restores to the original state convenient for outer tube 2.
The outer side wall surface of the outer tube 2, inner tube 3 and conduit 4 flushes, beautiful.
The inside oblique cutting of the right end nozzle of the outer tube 2 forms the first inclined-plane 9, the connection of said inner tube 3 and inner catheter 7
To locate oblique processing and forms the second inclined-plane 10, the inner sidewall of the outer tube 2 is contacted with the fitting of the lateral wall of inner catheter 7, and described first
Inclined-plane 9 is contacted with the matching fitting of the second inclined-plane 10, and the junction of inner tube 3 and inner catheter 7 is avoided to bend.
9 tilt angle on first inclined-plane is between 5~25 degree, 3~6 millimeters of the chamfer length on the first inclined-plane 9 it
Between, it avoids 9 length on the first inclined-plane too long, bearing capacity is caused to be deteriorated, 9 length on the first inclined-plane are too short, can not play using effect
Fruit.
Said inner tube 3 and inner catheter 7 are silica gel hose, soft, small with certain tensile strength, bending radius, are not easy to turn round
Knot.
The left side of the connector 6 is the first ring plate, and the right side of connector 6 is the second ring plate, and the first ring plate is located at limit
The left side of land 5, the second ring plate are located at the right side of limited ring dais 5, the inner ring integrally connected of first ring plate and the second ring plate,
The avris of second ring plate is contacted with the ontology inner sidewall of outer tube 2, and the ontology of the second ring plate integrally connects with the right end of inner catheter 7
It connects, good airproof performance, is convenient for water conservancy diversion, while inner catheter 7 will not distort.
The principles of the present invention and advantage: in clinical care, patient view 20 is used for Micropump, finds 18
Occur reflexed problem after when longer, when this patent infusion of drug, be affected by gravity, inner tube 3 and conduit 4 can under
It is curved, it is curved under the meeting of inner catheter 7 since the ontology reduction radius of inner tube 3 forms inner catheter 7, since the right end nozzle of outer tube 2 is cut
At the first inclined-plane 9, the oblique processing in the junction of inner tube 3 and inner catheter 7 forms the second inclined-plane 10, and two inclined-plane matchings are bonded, from
And make the junction of inner tube 3 and inner catheter 7 that there is buffering gradient, it is not easy to the case where bending, with inner tube 3 curved at present
It can pressed against with inner catheter 7 curved under outer tube 2, outer tube 2 is transparent modeling pipe, and side wall is relatively thin, and spring 8 is housed, and is restored and curved by spring 8
The influence of Qu Xingneng, outer tube 2 can when bending due to pressure increases under curved amplitude increase, pressure reduce and under curved amplitude
Reduce, so that arc-shaped shape when the entire compression of outer tube 2, so that inner tube 3 and the arc-shaped shape of inner catheter 7, connection is farther out
Conduit 4 can freely under curved hang, so that entire extension tube will not be bent, and can be automatically adjusted, always in arc shape
Or it is linear, infusion of drug is unblocked, it should be noted that if producing 2 higher cost of outer tube of built-in spring 8, that
Too hard plastics in the sorting of outer tube 2, can cannot be used using existing flexible and transparent modeling pipe in the market, this
Sample will cause outer tube 2 and can only stretch, cannot be bent, and the structure mentioned in specification is all chosen for transparent material in addition to spring 8,
Medical worker is facilitated to check in this way.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
