DETAILED DESCRIPTION

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] See also Figures 1 to 8 The utility model provides a technical solution: a double-lumen lumbar drainage tube, comprising a tube body 1, a drainage head 4, a flushing head 5 and a dredging head 10, wherein a drainage cavity 2 and a flushing cavity 3 are respectively provided inside the tube body 1, and the outlet ends of the drainage cavity 2 and the flushing cavity 3 are respectively connected with the drainage head 4 and the flushing head 5, and the middle parts of the flushing head 5 and the drainage head 4 are respectively provided with a first one-way valve 6;

[0033] The outer surface of the tube body 1 is provided with a scale coating 7 at equal intervals, and the scale coating 7 is made of a developing material;

[0034] The outer sleeve of the tube body 1 is provided with a sealing member 8, and a clearance hole is provided in the middle of the sealing member 8 for the tube body 1 to pass through. The inner wall of the clearance hole is fixed with a sealing ring 9 that contacts the surface of the tube body 1. Considering that when draining lumbar patients, it is necessary to make a self-made flushing head 5, and then the flushing head 5 and the drainage head 4 are tied together for drainage and flushing of the patient, but the current bundling method is easily affected by the surgical cavity, that is, the volume becomes larger after binding, which is easy to affect the patient, and the drainage liquid leaks from the surgical cavity and the gap of the pipeline. The tube body 1 of the utility model adopts a consistent double-lumen design, so that it can play the role of component flushing and drainage channel for the drainage part of the patient while ensuring that the volume of the surgical cavity occupied by the pipeline is reduced. In order not to affect the flushing and drainage functions, it is equipped with a dedicated first one-way valve 6, and a plurality of scale coatings 7 are designed on the surface of the tube body 1, which will help the user know the depth of the drainage inserted into the surgical cavity. At the same time, in order to prevent leakage at the drainage incision position, a sealing member 8 is designed.

[0035] Among them, the front end of the drainage head 4 is also connected to the dredging head 10, and the dredging head 10 is located on one side of the first one-way valve 6. A second one-way valve 11 is provided in the middle of the dredging head 10. A first dust cover 12 is threadedly connected to the outside of the dredging head 10, and a sealing gasket 13 is fixedly bonded to the inside of the first dust cover 12. By setting the dredging head 10, when the drainage cavity 2 is blocked, physiological saline can be injected into the dredging tube to dredge the blocked drainage cavity 2, thereby ensuring the normal drainage.

[0036] Among them, the ends of the flushing head 5 and the drainage head 4 are both provided with a protruding end 14 for resisting the internal groove of the second dust cover 15. The second dust cover 15 is provided to protect the flushing head 5 and the drainage head 4.

[0037] Among them, a cavity is opened inside the wall of the drainage head 4 and the flushing head 5 for inserting the V-shaped metal sheet 16. By inserting the V-shaped metal sheet 16 inside the wall of the drainage head 4 and the flushing head 5, medical staff can adjust the distance between the drainage head 4 and the flushing head 5 as needed, thereby making room for the pipe docking position. When adjusting, the V-shaped metal sheet 16 can be bent directly.

[0038] Among them, a dressing layer 17 is provided in the middle of the contact surface between the seal 8 and the patient's skin, a sealing ring 18 is fixed on the outside of the contact surface between the seal 8 and the patient's skin, and grooves for installing medical tape 19 are provided on both sides of the outside of the seal 8. By setting the dressing layer 17, an anti-inflammatory effect is played on the surgical incision site of the patient's skin tissue, preventing the drainage fluid from seeping out and causing infection at the incision site. The presence of the sealing ring 18 prevents the infiltration of external liquid and causing infection at the incision site.

[0039] Among them, positioning rods 20 are fixed at equal intervals inside each trough body, and two contact ends 22 for buckling the pressure plate 21 are provided at the end of each positioning rod 20, and a fixing hole matching the number of the positioning rods 20 is opened in the middle of the pressure plate 21. By setting the pressure plate 21 to cooperate with the positioning rods 20, the medical tape 19 is fixed inside the trough body. When assembling, the workers only need to align the opening of the medical tape 19 itself with the positioning rod 20, take out the pressure plate 21 and press it down. The contact end 22 of the positioning rod 20 is forced to close together and pass through the fixing hole of the pressure plate 21 and then reset to complete the fixation of the pressure plate 21. At this time, the medical tape 19 is fixed, and the medical tape 19 can be used to fix the seal 8 on the patient.

[0040] Among them, a fixing sleeve 24 for inserting the end of the spring 23 is symmetrically fixed to the middle end of the outer side of the seal 8, and a rubber ring 25 is fixed and adjusted at the end of the spring 23. Four positioning pieces 26 are integrally formed in the middle of the rubber ring 25, and the positioning pieces 26 are in contact with the surface of the tube body 1. The spring 23 is fixed by setting the fixing sleeve 24. During assembly, one end of the spring 23 is screwed into the fixing sleeve 24 and then rotated so that the fixing sleeve 24 at the other end is observed. At this time, the fixation of one end of the spring 23 is completed. Due to the presence of the spring 23, when the tube body 1 is pulled and folded, the spring 23 will be used for soft support to prevent the connection between the seal 8 and the drainage tube from folding, causing blockage of the drainage tube.
