In use, medical catheter 4 sets notch 1 from conduit and conduit is set and walked between notch 2 32, only conduit Set notch 1 and conduit set notch 2 32 the notch gross area be greater than 4 cross-sectional area of medical catheter just can ensure that it is medical Conduit 4 will not be by magnetic pedestal 2 when walking and magnetic lid 3 blocks or incarceration.Conduit is set notch 1 and is arranged at magnetic bottom Middle side part on seat 2, conduit set notch 2 32 and the lower middle side part of magnetic lid 3 are arranged, and the two position corresponds to each other, it is ensured that medical to lead Pipe 4 is smooth when walking, in addition the first flexible glue body 21 and the second flexible glue body 31 that are arranged between magnetic pedestal 2 and magnetic lid 3, The magnetic pedestal 2 of hard and magnetic lid 3 is avoided to oppress or contact 4 surface of medical catheter, it is ensured that the safety of medical catheter 4.Institute State conduit set notch 1 and conduit set 2 32 cross-sectional profile of notch include symmetrical semicircle, it is rectangle, trapezoidal and three It is angular.No matter that shape is used, is required to form medical catheter 4 in fixed medical catheter 4 and oppress, it is therefore desirable to protect Hold that conduit sets notch 1 and conduit is set the edge of notch 2 32 and do not contacted with fixed medical catheter 4.

In order to ensure that can prolong to 4 two sides of medical catheter when the first flexible glue body 21 and the second flexible glue body 31 compressing medical catheter 4 Exhibition, it is necessary to be reserved with after enough deformations space of extending to the first flexible glue body 21 and the second flexible glue body 31, that is to say, that first is soft Colloid 21 and the deformation of the second flexible glue body 31 remain in the space being contained between magnetic pedestal 2 and magnetic lid 3 after extending, this is just It is required that the sum of cross-sectional area of the first flexible glue body 21 and the second flexible glue body 31 and medical catheter 4 is equal to or slightly less than magnetic pedestal The cross-sectional area in space between 2 and magnetic lid 3.Otherwise, lumen quilt part or complete after medical catheter 4 is fixed is inevitably resulted in Portion shrivels；Or magnetic pedestal 2 and magnetic lid 3 can not correctly cover conjunction, 4 fixed effect of medical catheter is had a greatly reduced quality.

As it was noted above, only the first flexible glue body 21 and the second flexible glue body 31 are highly and greater than magnetic pedestal 2 and magnetic sucking cap Just gap width when body 3 attracts each other fixed is able to achieve the preferable grip effect of fixed effect, under the premise of this, in order to reality The sum of existing first flexible glue body 21 and the cross-sectional area of the second flexible glue body 31 and medical catheter 4 are equal to or slightly less than magnetic pedestal 2 The cross-sectional area in gap between magnetic lid 3 just necessarily requires the length of the first flexible glue body 21 and the second flexible glue body 31 small The width in gap between magnetic pedestal 2 and magnetic lid 3.

Further, middle side part is equipped with flexible glue recess 1 on the magnetic pedestal 2, and the first flexible glue body 21 is embedded in flexible glue It is recessed in one 23.The lower middle side part of the magnetic lid 3 is equipped with flexible glue recess 2 33, and the second flexible glue body 31 is embedded in flexible glue recess two In 33.The middle part of flexible glue recess 1 is arranged in the first flexible glue body 21, and it is recessed that 21 volume of the first flexible glue body is less than flexible glue Fall into one 23 volume.The middle part of flexible glue recess 2 33 is arranged in the second flexible glue body 31, and the second flexible glue body 31 is small in size In the volume of flexible glue recess 2 33.

By the way that flexible glue recess 1 and the setting flexible glue of magnetic lid 3 recess 2 33, the first flexible glue body is arranged in magnetic pedestal 2 21 and the second flexible glue body 31 can be safe the gap being fixed between magnetic pedestal 2 and magnetic lid 3 in, avoid because of after being pressurized the Origin-location is deviated after one flexible glue body 21 and the deformation of the second flexible glue body 31, or even de- with magnetic pedestal 2 and 3 bottom of magnetic lid From.The flexible glue one 23 pair of first flexible glue body 21 that be recessed has position-limiting action, with origin-location when making the first flexible glue 21 compressive deformation of body Extend to surrounding at center, it is ensured that remained at after 21 compressive deformation of the first flexible glue body in flexible glue recess 1, be unlikely to deviate from soft Glue recess 1.Similarly, the flexible glue 2 33 pair of second flexible glue body 31 that be recessed has position-limiting action, when making the second flexible glue 31 compressive deformation of body Extended centered on origin-location to surrounding, it is ensured that it is remained at after 31 compressive deformation of the second flexible glue body in flexible glue recess 2 33, It is unlikely to deviate from flexible glue recess 2 33.It is recessed 2 33 pair of first flexible glue body 21 and the second flexible glue by flexible glue recess 1 and flexible glue The position-limiting action of body 31, it is ensured that product can work normally, the fixed effect played stably.

It excessively lacks of proper care to make appearance be unlikely to ratio, 21 volume of the first flexible glue body is less than the volume of flexible glue recess 1, Second flexible glue body, 31 volume is less than the volume of flexible glue recess 2 33, such magnetic fixed two main part magnetic pedestals 2 and magnetic 3 comparison match of lid, size the first flexible glue body 21 appropriate and the second flexible glue body 31 oppress 4 two sides of medical catheter respectively, Most stable of fixed effect can be played.Certainly, as long as can guarantee the volume of the first flexible glue body 21 and the second flexible glue body 31 and be less than Flexible glue recess 1 and flexible glue recess 2 33 volume and, can also reach fixed effect, only ratio is uncoordinated, fixed effect compared with Difference.

In order to further enhance the fixed effect of medical catheter 4, as shown in Fig. 1, Fig. 4, Fig. 6, Fig. 7 and Fig. 9, described first Embedding slot 1 is equipped on the upside of flexible glue body 21, it is corresponding, embedding slot 2 30 is equipped on the downside of the second flexible glue body 31.The embedding slot one 20 and embedding slot 2 30 trend and conduit set notch 1 and conduit to set the trend of notch 2 32 consistent.The embedding slot The sum of one 20 and the cross section of embedding slot 2 30 are less than 4 cross-sectional area of medical catheter.The embedding slot 1 and embedding slot two 30 cross-sectional profile includes symmetrical semicircle.

The trend of the embedding slot 1 and embedding slot 2 30 and conduit set notch 1 and conduit sets notch 2 32 Trend it is consistent, can reduce the bending of medical catheter 4 to the full extent, keep the maximum degree of mobility of medical catheter 4.Avoid by Notch 1 is set in the trend and conduit of embedding slot 1 and embedding slot 2 30 and what conduit set notch 2 32 moves towards different The bending of medical catheter 4 caused by causing even gives a discount.

By the way that embedding slot 1 and embedding slot 2 30, energy is arranged in the first flexible glue body 21 and 31 corresponding position of the second flexible glue body Stable region is formed in the fixed medical catheter 4 of the first flexible glue body 21 and the second flexible glue body 31, avoids medical catheter 4 when being pressurized the It is slid between one flexible glue body 21 and the second flexible glue body 31, prevents medical catheter 4 from partly or entirely slipping when being pressurized to the first flexible glue Outside gap between body 21 and the second flexible glue body 31.When fixed medical catheter 4, it is nested with when by medical catheter 4 in the first flexible glue body Between 21 embedding slot 1 and the embedding slot 2 30 of the second flexible glue body 31,2 30 pairs of medical catheters of embedding slot 1 and embedding slot 4 form the gripping effect of environmental protection, when the first flexible glue body 21 and the second flexible glue 31 compressive deformation of body, embedding slot 1 and embedding slot The environmentally friendly curable grip of 2 30 pairs of medical catheters 4 is gradually reinforced, and can to a certain extent stablize medical catheter 4 in one 20 He of embedding slot In embedding slot 2 30, medical catheter 4 is avoided to slip to side

If the sum of the embedding slot 1 and cross section of embedding slot 2 30 should be less than 4 cross-sectional area of medical catheter, this The inner surface and medical catheter 4 of embedding slot 1 and embedding slot 2 30 when sample, the first flexible glue body 21 and the second flexible glue body 31 are pressurized Outer surface can come into full contact with, and move up and be looped around medical catheter 4 part the first flexible glue body 21 and the extruding of the second flexible glue body 31 Side, the realization on 4 cross section of medical catheter without dead angle is around the fixed effect held.Should be 4 section of medical catheter is mostly The cross-sectional profile of circle, the embedding slot 1 and embedding slot 2 30 is preferably symmetrical semicircle.To reach optimal fixation Effect.

In order to further strengthen the fixed effect of 2 30 pairs of medical catheters 4 of embedding slot 1 and embedding slot, the embedding slot 1 and the inner surface that is recessed of embedding slot 2 30 several non-slip textures 6 are set.Non-slip texture 6 includes and embedding slot 1 and sets The vertical band of 2 30 long axis of slot, check design, rice character design.When it is implemented, embedding slot one can also be closed in the first flexible glue body 21 20 are nearby arranged anti-skid chequer 6, close on setting anti-skid chequer 6 near embedding slot 2 30 in the second flexible glue body 31.When the first flexible glue body 21 When being pressurized and deform with the second flexible glue body 31, the anti-skid chequer 6 that embedding slot 1 and embedding slot 2 30 are nearby arranged can be touched The surface of medical catheter 4.The setting of anti-skid chequer 6 can further increase medical catheter 4 and embedding slot 1, embedding slot 2 30 and Its coefficient of friction for closing on flexible glue block enhances to 4 fixed effect of medical catheter.
