Detailed Description

The medical anti-bending drainage catheter provided by the utility model is explained and explained in detail below by combining the attached drawings of the specification.

The embodiment specifically discloses a medical anti-bending drainage catheter, which comprises an internal section 1 and an external section 2, wherein the internal section 1 is inserted into the skin of a patient during drainage, and the external section 2 is left outside the skin, as shown in fig. 1. The medical anti-bending drainage catheter is made of materials such as polyurethane or silicon rubber.

The in-vivo section 1 comprises a straight section 11 and an arc section 12, the tail end of the straight section 11 is fixedly connected with the in-vitro section 2, and the inner diameter of the in-vitro section is larger than that of the straight section, so that smooth drainage can be ensured; the outer diameter of the external section is larger than that of the straight section, so that the external section can be left outside the body. The front end of the straight section 11 is fixedly connected with the circular arc section 12, and is preferably integrally formed. The wall of the straight section 11 is internally embedded with a supporting spring 3, the supporting spring 3 and the straight section 11 are coaxially arranged, and the supporting spring 3 is completely embedded in the wall of the internal section 1, so that the inner wall of the drainage catheter is ensured to be smooth, and the blockage caused by the attachment of fibers, thrombus or other sediments is prevented; the supporting spring 3 plays a supporting role, prevents the drainage catheter from being forced to be closed after the drainage catheter penetrates out of the skin or the intradermal section, and ensures smooth drainage; meanwhile, the supporting spring 3 has certain elasticity and bending degree, when the drainage catheter slightly deforms, the supporting spring 3 can also deform adaptively, but the hardness and the strength of the supporting spring can ensure that the drainage catheter cannot be broken and blocked, the drainage catheter can smoothly enter the skin, and the discomfort of a patient is reduced. One or more drainage holes 121 are formed in the wall of the circular arc section 12 close to the circle center, and the drainage holes 121 are arranged along the length direction of the circular arc section 12. The anterior segment of internal section 1 sets up to circular-arc, and drainage hole 121 sets up at the inner circle, and it takes place to reduce drainage hole 121 and attach the wall phenomenon, and the guarantee drainage is unobstructed.

The vertical distance from the tail end of the supporting spring 3 to the front end of the circular arc section 12 is 10-20 cm. Since the depth of the drainage catheter inserted into the skin is generally between 10 and 20cm, this embodiment ensures that the support spring 3 can be fully inserted into the skin for support. Moreover, the supporting spring 3 is arranged at a position close to the tail end of the in-vivo section 1, so that the drainage catheter can smoothly penetrate out of the skin. Preferably, the front end of the supporting spring 3 is at a certain vertical distance from the front end of the circular arc section 12, so that the direction change of the intracutaneous segment 1 is facilitated.

The front end of the arc section 12 is a tip which is convenient for skin puncture. Preferably, the wall of the tip of the arc segment 12 close to the center of the circle is arc-shaped, and the wall far from the center of the circle is an inclined plane inclined towards the center of the circle. The arc-shaped inner ring of the tip is convenient for the drainage catheter to turn in the skin, so that the discomfort of a patient during turning is reduced, and the inclined plane is convenient for puncturing the skin.

The tail end of the internal section 1 or the joint of the internal section 1 and the external section 2 is fixed with a fixed wing 4. The fixed wing 4 fixes the drainage catheter when being convenient for drainage, avoids causing the patient discomfort because of the drainage catheter dislocation that factors such as patient's disorder caused, and influences the drainage effect. In the preferred embodiment, two fixing holes 41 are provided on the fixing wing 4, and the two fixing holes 41 are distributed on both sides of the body section 1. The left and right sides of the drainage catheter can be fixed by the binding bands passing through the two fixing holes 41, and the fixing firmness is ensured.

The tail end of the external section 2 is fixed with a drainage tube joint 5. The drainage tube joint 5 is connected with a pressure device or a drainage bottle and other containers, the drainage tube joint 5 is used for being connected with a tubular structure, a common tube joint can be selected, and the drainage tube joint can be in threaded connection or buckled connection.

The tip of drainage catheter firstly punctures skin, then 1 whole entering subcutaneous of internal section, after the drainage, when drainage catheter worn out skin, need follow and skin vertically direction change immediately more with the skin horizontally direction, the drainage catheter of this embodiment buries one section supporting spring in drainage catheter's wall endocyst under the prerequisite that does not change the material, plays the supporting role, has anti ability of rolling over, has avoided the occlusive phenomenon of rolling over to take place, guarantees that the drainage is unobstructed. The drainage hole 121 of the anterior segment of the drainage catheter is positioned in the inner ring of the arc segment 12, so that the phenomenon that the drainage hole 121 is attached to the wall is reduced, and the drainage is further ensured to be smooth.
