DETAILED DESCRIPTION
[0022] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: an anti-blockage thoracic surgical drainage fixing device, comprising a drainage bottle 1 for collecting drainage fluid, which is placed in a stable position on the ground when in use to avoid tilting, tilting, and collision;
[0023] One end of the drainage tube 2 is connected to the drainage bottle 1 and is used to drain the accumulated fluid into the drainage bottle 1;
[0024] The other end of the drainage tube 2 is connected to a body-fitting fixing connection device 3, which is fixed to the patient's body to maintain the stability of the connection between the drainage tube 2 and the patient's chest cavity to prevent the drainage tube 2 from falling off;
[0025] The drainage tube 2 is connected to an anti-clogging mechanism 11, which is used for flushing the drainage tube 2 to prevent clogging.
[0026] Among them, the close-fitting fixing connection device 3 includes a bottom tape 4, an adjustment mechanism 5 and a tape opening 7; the bottom tape 4 is a medical tape, which is used to be pasted on the patient's drainage port. The bottom tape 4 is provided with a tape opening 7, and the tape opening 7 is provided with an adjustment mechanism 5.
[0027] Among them, the adjustment mechanism 5 includes an adjustment track 8 and an adjustment ring 9. The adjustment track 8 is arranged on both sides of the tape opening 7. The adjustment ring 9 is used to slide on the adjustment track 8. The adjustment ring 9 is provided with a ring opening 10. The drainage tube 2 is used to pass through the ring opening 10 and the tape opening 7 and be connected to the patient's drainage port.
[0028] Among them, a first protrusion 18 and a first groove 19 are provided on the inner walls at both ends of the adjustment track 8, and a second protrusion 20 and a second groove 21 are provided on the outer walls at both ends of the adjustment ring 9. The first protrusion 18 and the first groove 19 cooperate with the second protrusion 20 and the second groove 21 to fix the adjustment ring 9, and the adjustment track 8 and the adjustment ring 9 are both made of medical plastic material. A certain deformation can be generated between the adjustment track 8 and the adjustment ring 9, so that the adjustment ring 9 can slide up and down in the adjustment track 8 to adjust the position.
[0029] Among them, a hollow slide groove 22 is opened in the middle part of the outer wall of both ends of the adjustment track 8, a slider 23 is arranged in the hollow slide groove 22, and one end of the fastening screw 24 is used to pass through the slider 23 and screw into the adjustment ring 9 to fix the adjustment ring 9.
[0030] The fixing mechanism 6 is arranged on the adjusting ring 9 and is used for fixing the drainage tube 2 .
[0031] The tape opening 7 is larger than the ring opening 10 .
[0032] The fixing mechanism 6 is configured as an existing clamping chuck for tightening one end of the drainage tube 2 .
[0033] Among them, the anti-clogging mechanism 11 includes a flushing component 12 and a negative pressure pump 13; one end of the negative pressure pump 13 is connected to the lower part of the drainage pipe 2, the flushing component 12 is connected to the upper part of the drainage pipe 2, and the flushing component 12 also includes a pulse water pump 14, a flushing pipe 15, a flushing tank 16 and a solenoid valve 17; one end of the pulse water pump 14 is connected to the upper part of the drainage pipe 2, and the other end of the pulse water pump 14 is provided with a flushing tank 16. The pulse water pump 14 and the flushing tank 16 are connected through the flushing pipe 15, and a solenoid valve 17 is provided below the connection between the pulse water pump 14 and the drainage pipe 2.
[0034] The flushing tank 16 is filled with a flushing agent or physiological saline for preventing clogging.
[0035] The pulse water pump 14 is adjustable in multiple gears.
[0036] Among them, the drainage tube 2 is provided with a protective sleeve 25 on the outside, and the protective sleeve 25 can be installed and removed; by setting the protective sleeve 25, the drainage tube 2 is prevented from being squeezed and deformed. At the same time, even if it is bent, the drainage tube 2 is prevented from being completely cut off due to the increase in the curvature radius.
[0037] Threaded caps are provided at both ends of the protective sleeve 25 and are threadedly connected to the ring opening 10 and the drainage bottle 1 respectively.
[0038] The protective sleeve 25 is a stainless steel corrugated tube, which can avoid being squeezed and deformed, and can also avoid being interrupted by excessive bending.
[0039] Wherein, the drainage bottle 1 is provided with an exhaust hole 26 .
[0040] Working process: before using the device, first put the protective sleeve 25 on the drainage tube 2, insert one end of the drainage tube 2 into the drainage bottle 1, and connect and fix it with the threaded cap at one end of the protective sleeve 25 and the threaded cap at the bottle mouth of the drainage bottle 1. Then, stick the bottom adhesive tape 4 on the patient's drainage port, insert the drainage tube 2 into the chest cavity through the ring mouth 10 and the adhesive tape mouth 7, and then tighten and fix the other end of the drainage tube 2 through the fixing mechanism 6. After the drainage tube 2 is inserted, connect and fix the threaded cap at the other end of the protective sleeve 25 with the threaded cap at the ring mouth 10.
[0041] The accumulated fluid flows into the drainage bottle 1 along the drainage tube 2, and the drainage bottle 1 is used to collect the accumulated fluid;
[0042] If the position of the adjusting ring 9 needs to be adjusted, the adjusting ring 9 is grasped and slid upward or downward in the adjusting track 8. When the adjusting ring 9 slides upward or downward, it also drives the slider 23 and the fastening screw 24 to move together, so that the fastening screw 24 moves along the hollow slide groove 22. After the adjusting ring 9 moves upward or downward to a suitable position, the adjusting ring 9 is fixed by the first concave-convex groove of the adjusting ring 9 and the second concave-convex groove of the adjusting track 8. After being fixed, the fastening screw 24 is tightened into the adjusting ring 9, so that the first concave-convex groove of the adjusting ring 9 and the second concave-convex groove of the adjusting track 8 cooperate more closely, thereby improving the fixing effect of the adjusting ring 9.
[0043] A water flow sensor is arranged on the drainage tube 2; the anti-blocking mechanism 11 includes a microprocessor; when the accumulated fluid flows downward in the drainage tube 2, it is detected by the water flow sensor, and a signal is sent by the water flow sensor. The microprocessor is used to receive the signal sent by the water flow sensor. When the water flow sensor detects that the drainage fluid flow rate is reduced, which may be caused by blockage, the water flow sensor sends a detection signal, and then the microprocessor is used to receive the signal sent by the water flow sensor. After the microprocessor receives the signal, the microprocessor controls the electromagnetic valve 17 to be closed, and then the microprocessor controls the electromagnetic valve 17 to be closed. The processor starts the pulse water pump 14, and the flushing agent or saline in the flushing tank 16 is sucked into the flushing pipe 15 through the pulse water pump 14, and then sprayed into the drainage tube 2 along the flushing pipe 15, and finally the blockage is flushed back into the chest cavity along the drainage tube 2. Since the blockage is mostly coagulated blood clots, the flushed back blockage does not cause harm to the body; then the solenoid valve 17 and the negative pressure pump 13 are opened by the microprocessor, and the negative pressure pump 13 generates negative pressure to suck the effusion and the blockage into the drainage bottle 1, and the negative pressure pump 13 is used to improve the suction effect of the effusion and the blockage.
