Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a flushing liquid siphon device. Background Art

[0002] Some urological surgeries such as percutaneous nephrolithotomy, transurethral resection of the prostate, and transurethral resection of bladder tumors require the use of a large amount of flushing fluid. If the operation time is long and a lot of flushing fluid is used, medical staff will need to frequently replace the drainage bucket. At this time, the surgeon is required to stop the operation and cooperate in replacing the drainage bucket. When medical staff replace the drainage bucket, there is a risk of contact with the patient's body fluids, which also increases the workload of medical staff.

[0003] To solve this problem, the first thing that comes to mind is to replace the drainage bucket with a larger volume, such as an 80-liter drainage bucket. However, the current hospital procurement system, equipment management system, surgical operation process and other systems are relatively fixed, and large-capacity drainage buckets take up a lot of space and are inconvenient to carry. Obviously, we cannot simply use a larger-capacity drainage bucket to solve this problem. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0023] Reference Figures 1 to 4 A urological surgical flushing fluid drainage siphon device comprises a siphon tube 1, one end of the siphon tube 1 is a water inlet end 11, and the other end is a negative pressure end 12, the water inlet end 11 is provided with a weighted ball 13, and the negative pressure end 12 is provided with a negative pressure interface 14 for connecting a negative pressure aspirator; the siphon tube 1 is provided with at least two manifolds 2 at different positions, each of the manifolds 2 is provided with a manifold switch 21, and a negative pressure switch 15 is installed at a position of the siphon tube 1 close to the negative pressure interface 14; the structure of the negative pressure switch is the same as that of the manifold switch, which will not be described in detail here; the siphon tube 1 is provided with a number of not less than the manifold switches 21. 2 number of fixing clips 16; the siphon tube of this embodiment is provided with a plurality of manifolds, and by controlling the negative pressure switch and the manifold switch, the siphon tube forms a siphon effect, and the flushing fluid in the drainage bucket that tends to be filled is transferred to other drainage buckets, without changing the existing management system. First, it does not hinder the doctor's surgical operation, maintains the continuity of the operation, and shortens the operation time; second, it is easy to operate, ensures the continuity of drainage, avoids medical staff from contacting the flushing fluid with patient body fluid components, and avoids nosocomial infection; third, it prevents the flushing fluid from overflowing and polluting the surgical environment; fourth, it is convenient to observe the flushing fluid in the bucket and facilitate the postoperative disposal of the flushing fluid.

[0024] The manifold switch 21 includes a seat body 22 and a switch rocker 23. The seat body 22 is in the shape of a groove formed by two vertical walls and a transverse wall. The middle part of the switch rocker 23 is hinged with the two vertical walls. A siphon passage for the siphon 1 to pass through is formed between the seat body 22 and the switch rocker 23. Slide grooves 24 are also provided at both ends of the vertical walls. A positioning groove 25 is provided at the bottom of the slide groove 24. A directional guide groove 25 is provided between the bottom of the slide groove 24 and the positioning groove 25. The switch seesaw 23 is provided with a slide bar 231 extending into the slide slot 24 and the positioning slot 25, and a clamping block 232 is provided at one end of the switch seesaw 23. When the slide bar 231 is located in the positioning slot 25 near one end of the clamping block 232, the clamping block 232 and the transverse wall clamp the siphon tube 1 to turn off the siphon tube 1. By pressing the switch seesaw, the clamping block is pressed down or tilted up to control the on and off of the manifold. The switch seesaw is fixed to the seat in a hinged manner. When medical staff replace the spare drainage bucket, they can open or close the manifold switch by pressing the switch seesaw with one hand, which is convenient for medical staff to operate.

[0025] The vertical wall is provided with a hinge hole 26, and hinge shafts 233 inserted into the hinge holes 26 are provided on both sides of the switch rocker 23; a first deformation portion 234 is provided between the hinge shaft 233 and the slide bar 231, and when the slide bar 231 is located in the slide groove 24, the first deformation portion 234 is in an elastic compression state; the first deformation portion 234 is an arc-shaped arc that is concave downward; a second deformation portion 235 is provided between the clamping block 232 and the adjacent slide bar 231, and when the slide bar 231 is located in the positioning groove 25, the second deformation portion 235 is in a stress-deformed state; at this time, the first deformation portion recovers part of the deformation, but it still has a certain deformation, so that the position of the switch rocker remains fixed; the second deformation portion 235 is an arch that arches upward.

[0026] The surface of the switch rocker 23 is provided with anti-skid patterns 236. During surgery, medical staff and doctors all wear sterile medical gloves, which come into contact with the flushing fluid. At this time, pressing the manifold switch is prone to slipping. In order to facilitate doctors to operate the manifold switch during surgery, the present embodiment provides anti-skid patterns on the surface of the switch rocker 23 to prevent medical staff from slipping when pressing the switch rocker.

[0027] The fixing clip 16 is an integrally formed "n" shape, and the inner wall of the fixing clip 16 is symmetrically provided with protrusions 161, which divide the fixing clip 16 into a tube clamping portion 162 for fixing the siphon tube 1 and a barrel clamping portion 163 for fixing on the drainage barrel; the fixing clip of this embodiment is integrally injection-molded from hard plastic. Since the fixing clip is used to fix the position of the siphon tube, medical staff do not touch the fixing clip during surgery, so the fixing clip does not require very high sterility requirements.

[0028] During specific use, the water inlet end of the siphon tube is extended into the drainage bucket, the discharge end of the manifold is extended into the spare drainage bucket, the negative pressure interface is connected to the negative pressure suction device, and the laparoscopic drainage tube sucks the flushing fluid sucked out during the operation into the drainage bucket. When the drainage bucket is full, the manifold switch is closed, the negative pressure switch is turned on, and the flushing fluid in the drainage bucket is sucked to the negative pressure end of the siphon tube by the negative pressure suction device. Then, the negative pressure switch is closed, and the manifold switch is turned on to allow the flushing fluid in the siphon tube to flow into the spare drainage bucket along the manifold under the action of gravity. At this time, due to the height difference between the flushing fluid in the drainage bucket and the spare drainage bucket, according to the siphon principle, the flushing fluid in the drainage bucket will be siphoned to the spare drainage bucket. Use the drainage bucket until the liquid levels in the two buckets tend to be flush. At this time, the medical staff only needs to close the manifold switch above and open the manifold switch of the other manifold to let the flushing liquid in the siphon tube flow down along the other manifold, and then use the siphon principle to siphon the flushing liquid in the drainage bucket into another spare drainage bucket again until the flushing liquid in the drainage bucket is less. The technical solution adopted in this embodiment does not require the medical staff to replace the drainage bucket when transferring the flushing liquid in the drainage bucket, thereby avoiding the medical staff from contacting the flushing liquid with the patient's body fluid components, avoiding medical-induced infection, not hindering the doctor's surgical operation, maintaining the continuity of the operation, and shortening the operation time.
