Example one

Please refer to fig. 1 to 4 simultaneously, the utility model discloses a preferred embodiment provides a drainage tube convenient to normal position is changed, including the hose body and set up multiunit water conservancy diversion hole 40 on the hose body lateral wall, wherein, the hose body includes external pipe 10 and invasion pipe 11, the external diameter of invasion pipe 11 is less than the external diameter of external pipe 10, external pipe 10 and invasion pipe 11 integrated into one piece just set up to smooth arc transition in external pipe 10 and the junction of invasion pipe 11, the hose body and support blade 2 use silica gel to make, silica gel has soft texture, good elasticity, to the good characteristics of little biocompatibility of tissue damage, from this there is not the phenomenon appearance such as irritability and irritability, can keep somewhere for a long time. A plurality of sets of supporting blades 2 are fixed on the outer side of the invading pipe 11, and the plurality of sets of supporting blades 2 are fixedly connected on the outer side wall of the hose body, so that a clearance cavity 30 is formed between the supporting blades 2 and the side wall of the invading pipe 11.

As shown in fig. 1 to 3, the support blade 2 includes a connection portion 20 and a pressure receiving portion 22, the connection portion 20 and the pressure receiving portion 22 are integrally formed, and a connection portion between the connection portion 20 and the pressure receiving portion 22 is an arc-shaped bridge 21 with a convex portion facing a side away from a circle center of the intrusion pipe 11. On the one hand because the arc bridge 21 that sets up has great intensity and can bear the certain pressure of tissue on every side and not collapse and then guaranteed the existence of clearance cavity 30, on the other hand the outer wall of arc bridge 21 is level and smooth to be difficult to cause the tissue damage, and arc bridge 21 can take place deformation when having great pressure oppression simultaneously and reduce the volume of clearance cavity 30 and then reduce the external diameter so that smoothly pass through internal narrow department. The connecting portion 20 is fixedly provided on the side wall of the intrusion pipe 11, and the pressure receiving portion 22 is overlapped on the adjacent support blade 2. And a plurality of sets of support blades 2 are fixedly arranged on the intrusion pipe 11 along the same circumferential direction (clockwise or counterclockwise). With this arrangement, when the intrusion tube 11 penetrates into a narrow part of a human body, the intrusion tube 11 is rotated in a certain direction (clockwise or counterclockwise), the pressure receiving portion 22 is moved toward the side of the support blade 2 to which it is overlapped to increase the area of the overlapped portion, so that the diameter of the outer tube diameter formed by the support blade 2 is reduced to pass through the narrow part, and at the same time, the support strength of the support blade 2 is further enhanced due to the increase in the area of the overlapped portion, and the existence of the clearance cavity 30 at the narrow part can be ensured.

As shown in fig. 1, the external body tube 10 and the support blades 2 are provided with depth markings 221, the depth of insertion of the invasive tube 11 can be grasped in real time by the depth markings 221, the invasive tube 11 is provided with a plurality of sets of radiographic marking points 110, and the radiographic marking points 110 are used for imaging under X-ray irradiation, whereby the specific position of the invasive tube 11 in the body can be displayed more accurately. When the ray marking points 110 are performed, two sets of ray marking points 110 are required to be arranged at the end of the invasion tube 11 to reflect the position of the front end of the invasion tube 11, and a plurality of sets of ray marking points 110 are not arranged on the tube wall of the invasion tube 11 along the axial direction to reflect the posture of the invasion tube 11 in the human body.

As shown in fig. 4, when the drainage tube is replaced, the guide wire 50 is first inserted into the original hose body to the original drainage position, then the original drainage tube is pulled out, and a new drainage tube is sleeved on the guide wire 50 and then inserted, the guide wire provides a guide for the insertion of the new drainage tube, so that the new drainage tube can be inserted smoothly, on one hand, whether the new drainage tube reaches the original drainage position or not can be judged by comparing the position of the depth mark 221 arranged on the drainage tube with the standard scale mark 51 on the guide wire 50, and on the other hand, the insertion position of the new drainage tube can be judged by developing the ray mark point 110 on the new drainage tube under the X-ray. The head end of the guide wire 50 is set as a hydrophilic soft guide wire, and the hydrophilic soft guide wire has a hydrophilic coating on the surface, so that the surface becomes smooth after absorbing water, and tissue damage is not caused when the guide wire 50 is inserted.

Example two

As shown in fig. 5 and 6, the difference between the present embodiment and the first embodiment is only the structural form of the supporting blade 2, the supporting blade 2 in the present embodiment includes a top-supported arc piece 25 and a connecting bracket 23, the connecting bracket 23 is vertically fixed on the outer side of the intrusion pipe 11 along the axial direction of the intrusion pipe 11, and the top-supported arc piece 25 is fixedly disposed on the connecting bracket 23. The top bracing arc piece 25 is the arc sheet structure that is concentric circles with the invasion pipe 11, and linking bridge 23 fixes on the vertical line of symmetry of top bracing arc piece 25, and the resistance to deformation ability of the higher holistic drainage tube of the support intensity of this form support blade 2 is stronger, can reach the purpose of penetrating fast when penetrating the comparatively simple tissue of path shape that has higher intensity from this.

As shown in FIG. 6, in order to reduce the possibility of the catheter tube damaging surrounding tissues during penetration, the support blades 2 are provided with an arc-shaped introduction head 26 on the side close to the end of the invasive tube 11. Be equipped with the clearance between two sets of adjacent top bracing arc pieces 25, can reduce the area of contact of top bracing arc pieces 25 and human tissue on every side and then reduce the frictional force when penetrating through setting up the clearance, seted up multiunit conducting hole 24 on the linking bridge 23, can be convenient for drainage liquid through setting up conducting hole 24 and adjust the volume of the drainage liquid in each clearance cavity 30 of balanced in the free flow of each group clearance cavity 30.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
