Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a closed negative pressure flushing device that can recover flushing fluid. Background Technology

[0002] The main functions of a negative pressure irrigator include relieving pain, shortening treatment time, promoting wound healing, preventing infection, and improving surgical efficiency. By generating negative pressure, the irrigator can remove blood, pus, and other contaminants from the wound, keeping it clean, thus preventing infection and accelerating wound healing.

[0003] Chinese patent discloses a negative pressure irrigation device for nursing (CN203677616U), including a negative pressure device, an inlet tube, an insertion tube, and an inlet bag. A replenishment tube is located on one side of the upper part of the inlet bag, and the inlet tube is located at the lower part of the inlet bag. Several through holes are provided on the wall of the insertion tube. A control valve is provided at one end of the negative pressure device, and a negative pressure device handle is provided at the other end. A negative pressure tube is inserted into the negative pressure device handle, passing through the inlet bag and into the inlet tube. The insertion tube is inserted into the lower end of the inlet tube. An outlet valve is provided at the end of the negative pressure tube, installed on the inlet tube, passing through the inlet tube and connected to the negative pressure tube. The outlet valve is used to control the opening and closing of the negative pressure tube. An outlet passage is formed between the negative pressure device, the negative pressure device handle, and the negative pressure tube; an inlet passage is formed between the inlet bag, the inlet tube, and the insertion tube. This utility model has a simple structure, is easy to use, and provides smooth inlet and outlet of fluids, minimizing the patient's pain during intubation. Current negative pressure irrigators require incision of the wound before rinsing, which slows down the patient's healing process. Furthermore, a separate device is needed to absorb the irrigating fluid, which can easily cause blockage of the tubing due to the presence of blood clots, reducing absorption efficiency and the patient's treatment rate. Therefore, a closed-loop negative pressure irrigator capable of recovering the irrigating fluid is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that current negative pressure flushers are prone to clogging after absorbing flushing fluid, and to propose a closed negative pressure flusher that can recover flushing fluid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a closed negative pressure flushing device capable of recovering flushing fluid, comprising a storage bladder and a fixing cap, wherein a drainage tube is fixedly installed at the output end of the storage bladder, an injection tube is connected to the side wall of the drainage tube, and an anti-clogging component is provided on the inner wall of the fixing cap.

[0006] The anti-clogging component includes a retaining ring, the outer surface of which is fixedly connected to the inner wall of the retaining cap, and a connecting rod is fixedly installed on the inner surface of the retaining ring.

[0007] As a further description of the above technical solution:

[0008] A fixed plate is fixedly installed at one end of the connecting rod, and a rotating rod is fixedly installed on the side wall of the fixed plate.

[0009] As a further description of the above technical solution:

[0010] One end of the rotating rod extends into the interior of the liquid outlet pipe, and a positioning ring is fixedly installed on the outer surface of the rotating rod.

[0011] As a further description of the above technical solution:

[0012] A positioning rod is fixedly installed on the outer surface of the positioning ring, and a cleaning rod is fixedly installed on the side wall of the positioning rod.

[0013] As a further description of the above technical solution:

[0014] The outer surface of the injection tube is connected to an outlet tube, and the outer surface of the outlet tube is provided with a limiting groove. The inner wall of the limiting groove is rotatably connected to the inner wall of the fixing cap.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the fixing cap is threaded with a connecting pipe, and a negative pressure bottle is fixedly installed at one end of the connecting pipe.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting an anti-clogging component, the fixing cap can be rotated during the absorption of rinsing liquid in the negative pressure bottle. At this time, the fixing cap will drive the fixing ring to rotate, thereby driving the fixing plate to rotate synchronously through the connecting rod. The fixing plate will drive the rotating rod to rotate inside the liquid outlet pipe. Under the action of the positioning ring, the positioning rod drives the cleaning rod to rotate, breaking up the blood clots in the rinsing liquid. This avoids sudden blockage during the negative pressure absorption process, ensuring the stability of the negative pressure rinsing device and improving the efficiency of waste liquid absorption.

[0019] 2. In this utility model, a negative pressure bottle is provided, and the syringe is connected to the injection tube. Under the action of the syringe, the rinsing solution is squeezed into the drainage tube. The rinsing solution cleans the wound through the drainage tube. When the switch on the negative pressure bottle is turned on, the cleaned rinsing solution is drawn into the outlet tube after passing through the drainage tube under the action of the negative pressure bottle. Then, it flows into the negative pressure bottle through the connecting tube. Then, the normal exudate is drawn into the storage bladder through the drainage tube, realizing direct rinsing with the drainage tube without cutting open the wound for rinsing. This reduces the damage to the patient, can accelerate the patient's healing speed, and can also absorb the rinsing solution after rinsing, avoiding the possibility of the rinsing solution flowing around and causing infection in other parts of the body, thus ensuring the safety of the negative pressure rinsing device.

[0031] Working principle: Connect the syringe to the injection tube 3, and then squeeze the flushing fluid into the drainage tube 2 under the action of the syringe. The flushing fluid cleans the wound through the drainage tube 2. Turn on the switch on the negative pressure bottle 6. Under the action of the negative pressure bottle 6, the cleaned flushing fluid is sucked into the outlet tube 4 after passing through the drainage tube 2, and then flows into the negative pressure bottle 6 through the connecting tube 5.
