Description
Technical field
This utility model belongs to manufacture technology field of medical appliance, particularly a kind of fixture of drainage catheter.
Background technology
China Patent No. 201120041947.9 discloses a kind of drainage catheter fixer, this fixture comprises stator, described stator top is provided with and the integrated fixed cover of stator, the center of fixed cover is provided be used to installing the drainage catheter centre bore, centre bore runs through fixed cover and stator, the excircle of described fixed cover is provided with annular groove, be installed with detachable clamp mechanism in the annular groove, described stator and fixed cover are provided with the joint-cutting that drainage catheter is installed, and are set with on the below fixed cover of described annular groove and are fixed in patient's smooth member with it.There is following weak point in this patented technology scheme: 1, when drainage catheter is installed, drainage catheter laterally is mounted to centre bore from the joint-cutting of stator and fixed cover.In this process, must stator and fixed cover be pulled open certain interval along joint-cutting, just can put into drainage catheter, it is comparatively inconvenient that operating process seems.In like manner, after finishing using, also there is this unhandy problem in dismountable.2, after finishing using in the unloading process, two ratchets of detachable clamp mechanism are misplaced up and down to finish dismounting.Yet detachable clamp mechanism is integral structure, and it is installed in the annular groove of fixed cover excircle, and when two ratchets were misplaced up and down, what be subjected to lower wall on the retaining collar connected in star stopped that this operating process is not easy yet.3, when assembling fixed cover and clamp mechanism, because clamp mechanism is one-body molded by material, and it has certain hardness, and when sandwiching the annular groove of fixed cover, its peristome will be pulled very greatly, and this process is easy to the clamp mechanism damage and scraps.
Summary of the invention
Deposit the problem of in use operation inconvenience, assembling inconvenience for solving above-mentioned prior art, the utility model discloses a kind of fixture of drainage catheter.
This utility model is taked following technical scheme: the fixture of drainage catheter, comprise fixed disk, snap close, fixed disk is made by soft prepared material, fixed disk be formed for the stretching through through hole of drainage catheter, the front of fixed disk forms projection, and described through hole extends to the bottom surface of fixed disk from the top of projection; Fixed disk is spliced relatively by halves, and splicing place vertically (namely from the top of projection to the bottom surface of fixed disk) runs through described through hole; Described snap close withholds by two that the limit is hinged to be formed, and withholds the limit for two and forms a protruding suitable clasp with fixed disk, and the diameter of described clasp is withheld relatively rotating and changing of limit with two; The two non-hinged ends of withholding the limit form suitable teeth, and the two non-hinged ends of withholding the limit are relative localization by both teeth snappings.
Preferably, the outer of fixed disk is circle-shaped, and described projection is cylindric, convexes to form the positive middle part in fixed disk.
Preferably, two non-hinged ends of withholding the limit of snap close respectively form corrugated attaching part, press two attaching parts, and making gradually two, to withhold the limit close, until two teeth of withholding the limit snap into correct position.
Preferably, snap close is withheld the limit by two and is rotatably assorted by hinge and forms.
The fixture of this utility model drainage catheter has advantage easy and simple to handle, and in assembling process, not only convenient, and not fragile parts, packaging efficiency is high.

Fig. 5 is the structure chart of embodiment one snap close.
The specific embodiment
Below in conjunction with accompanying drawing this utility model embodiment is elaborated.
Embodiment one: referring to Fig. 1-5, present embodiment comprises fixed disk 1, snap close 2, fixed disk 1 is made by soft prepared material, its outer is circle-shaped, positive middle part forms cylindrical protrusions 1-1 and central through hole 1-2, central through hole 1-2 extends to the bottom surface of fixed disk 1 from the top of protruding 1-1, be used for stretching through drainage catheter.Fixed disk 1 divides halves A, B along its a certain diameter, and this diameter vertically (namely from the top of projection to the bottom surface of fixed disk) runs through through hole, and namely fixed disk 1 is spliced by halves A is relative with B.
Snap close 2 is withheld limit 2-1,2-2 by two and is rotatably assorted by hinge 3 and forms, two withhold limit 2-1,2-2 form one with the suitable clasp 2-3 of the protruding 1-1 external diameter of fixed disk 1, the diameter of this clasp is withheld relatively rotating and changing of limit with two.The two non-hinged ends of withholding limit 2-1,2-2 form suitable teeth 2-1-1,2-2-1, two of this end withhold the limit near the time, can't be separated from by both teeth snappings, if in the time of both will being separated from, only need both are misplaced up and down, rotate dorsad again and get final product.
The two non-hinged ends of withholding limit 2-1,2-2 also form corrugated attaching part 2-1-2,2-2-2, finger presses two attaching parts, and making gradually two, to withhold the limit close, until two teeth of withholding the limit snap into correct position.Attaching part is set, has the advantage that is difficult for slip when withholding operation.
During use, first halves A, the B of fixed disk are aimed at drainage catheter and relatively splice, make the part of drainage catheter be in the central through hole place of fixed disk; Then the retaining ring part with snap close is placed in outside the projection of fixed disk, presses two attaching parts of snap close, and making gradually two, to withhold the limit close, until two teeth of withholding the limit snap into correct position, the location that drainage catheter is just reinforced.During dismounting, two teeth of withholding the limit that stagger are up and down rotated dorsad two again and are withheld the limit, and drainage catheter has just broken away from locking.
Because fixed disk of the present utility model is spliced relatively by halves, therefore, there is not the defective that institute's referenced patents document exists in the background technology, it has installs and dismantles easy advantage.
In addition, snap close of the present utility model is withheld the limit by two and is rotatably assorted by hinge and forms, and its rotational angle is large, and stops therefore, have assembling, the easy advantage of dismounting without any when staggering two teeth.
Those of ordinary skill in the art will be appreciated that; above embodiment illustrates this utility model; and be not that conduct is to restriction of the present utility model; as long as in essential scope of the present utility model, all will fall into protection domain of the present utility model to variation, the modification of the above embodiment.
