Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anti-blockage drainage device. Background Technology

[0002] In thoracic surgery, drainage devices are very common equipment. A search revealed that a Chinese patent (application number: 201710838270.3) discloses a thoracic surgical anti-blockage drainage device. It uses a hose to draw in air or liquid, and the waste gas or liquid enters a sealed container. When the hose is blocked, the one-way air inlet valve allows air to enter due to the low air pressure inside the sealed container, preventing damage to the medical negative suction pump. By moving or rotating the lever, the milling cutter agitates the liquid, breaking up blood clots for easy extraction. An electric slider drives a fixed pulley to press the hose in the U-shaped channel back and forth, reducing the blockage of blood clots. This device is simple to operate, highly practical, and has broad market application prospects.

[0003] For example, Chinese patent (application number: 201811559569.6) discloses a thoracic surgical anti-blockage drainage device. By setting up a drainage mechanism and using three delivery tubes, it can divert gas or liquid in the pleural cavity. Then, the filtration mechanism can isolate the sediment, and the filter element can perform further filtration, achieving the purpose of good filtration effect and good anti-blockage effect. The vacuum pump uses the vent pipe to extract the gas inside the recovery box, creating a negative pressure inside the recovery box, which can then guide the liquid inside the transition box into the recovery box, achieving the purpose of convenient drainage and good use effect.

[0004] However, the two patents mentioned above use relatively simple methods to achieve the anti-clogging effect. They either use multiple delivery tubes to divert the flow or crush the blood clots. They cannot combine the two methods, resulting in a poor anti-clogging effect. Therefore, improvements are needed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an anti-blockage drainage device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clog-preventing diversion device includes a diversion and storage mechanism and a diversion head. A diversion mechanism is provided between the feed hose of the diversion and storage mechanism and the diversion head. The diversion mechanism includes an installation structure on which four diversion hoses are installed. The installation structure includes a diversion shell, which is closed at both ends. Four equally spaced arc-shaped slots are provided on the side wall of the diversion shell, with open ends. The diversion hoses are secured in the arc-shaped slots, and both ends of each diversion hose are connected between the feed hose of the diversion and storage mechanism and the diversion head.

[0008] In order to break up the blood clot and ensure the drainage speed, four equally spaced arc-shaped plates are fixed on the outside of the diversion shell. The arc-shaped plates are open at both ends and cover the arc-shaped slots. The diversion tube matches the inner wall of the arc-shaped plate. After the diversion tube is locked in the arc-shaped slots, a part of the diversion tube extends into the diversion shell. The diversion shell is provided with a tube extrusion structure.

[0009] Specifically, in this utility model, the extrusion structure includes a motor horizontally mounted at one end of a diverter shell. The output shaft of the motor rotates and extends into the diverter shell. A rotating rod is provided inside the diverter shell. One end of the rotating rod is fixed to the output shaft of the motor, and the other end is rotatably mounted on the other end of the diverter shell. The surface of the rotating rod is provided with a plurality of equally spaced extrusion tooth rows. Each extrusion tooth row includes four extrusion teeth. The two adjacent extrusion teeth are staggered, and the free ends of the extrusion teeth abut against the inner wall of the diverter shell.

[0010] Compared with the prior art, this utility model has the following advantages: the four diversion hoses in the diversion mechanism can ensure the normal operation of drainage. If one diversion hose is blocked, the other diversion hoses can still be used normally. The extrusion structure can drive the extrusion teeth to rotate in the diversion shell, crushing the blood clots in the diversion hoses and preventing blockage. In summary, the diversion of the four diversion hoses, combined with the crushing of blood clots, makes the anti-blockage effect better. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 As shown, this utility model provides an anti-blockage drainage device, including a drainage storage mechanism 1 and a drainage head 2, both of which are existing technologies. For the specific principle, please refer to Chinese Patent (Application No.: 201710838270.3). The drainage storage mechanism 1 includes the medical negative pressure pump, sealed container, air inlet pipe and other structures mentioned in the above patent, which will not be described in detail in this utility model. A diversion mechanism is provided between the feed hose of the drainage storage mechanism 1 and the drainage head 2. The diversion mechanism includes an installation structure, on which four diversion hoses 3 are installed. The installation structure includes a diversion shell 4, which is closed at both ends. Four equally spaced arc-shaped slots 4-1 are opened on the side wall of the diversion shell 4. The arc-shaped slots 4-1 are open at both ends. The diversion hoses 3 are locked in the arc-shaped slots 4-1. The two ends of each diversion hose 3 are connected between the feed hose of the drainage storage mechanism 1 and the drainage head 2.

[0020] like Figure 2-4 As shown, in order to crush the blood clot and ensure the drainage speed, four equally spaced arc-shaped plates 5 are fixed on the outside of the diversion shell 4. The arc-shaped plates 5 are open at both ends and cover the arc-shaped slots 4-1. The diversion tube 3 matches the inner wall of the arc-shaped plates 5. After the diversion tube 3 is inserted into the arc-shaped slots 4-1, part of the diversion tube 3 extends into the diversion shell 4. The diversion shell 4 is equipped with a tube extrusion structure.

[0021] like Figure 5-6 As shown, in this utility model, the extrusion structure specifically includes a motor 6 horizontally mounted at one end of a diverter housing 4. The output shaft of the motor 6 rotatably extends into the diverter housing 4 (a circular hole is provided on the diverter housing 4, and a bearing is assembled in the circular hole, with the output shaft of the motor 6 cooperating with the bearing). A rotating rod 7 is provided inside the diverter housing 4. One end of the rotating rod 7 is fixed to the output shaft of the motor 6, and the other end is rotatably mounted on the other end of the diverter housing 4 (mounted on the diverter housing 4 through a bearing). The surface of the rotating rod 7 is provided with a plurality of equally spaced extrusion tooth rows. The extrusion tooth rows include four extrusion teeth 8. The two adjacent extrusion teeth 8 are staggered, and the free end of the extrusion tooth 8 abuts against the inner wall of the diverter housing 4.

[0022] The working principle of this utility model is described in detail below: When the drainage head 2 is inserted into the patient's chest cavity, the medical negative pressure pump in the drainage storage mechanism 1 works to extract the liquid and gas in the chest cavity. The liquid and gas enter each drainage tube through the drainage head 2 for diversion. When moving within the diversion tube 3, the motor 6 is connected to an external power source and starts, driving each squeezing tooth 8 on the rotating rod 7 to rotate, squeezing the diversion tube 3 and crushing the blood clot. The crushed liquid and gas enter the sealed tank through the feed tube.

[0023] Finally, the most significant contribution of this invention is that the four diversion hoses 3 in the diversion mechanism can ensure normal drainage. If one diversion hose 3 is blocked, the other diversion hoses 3 can still be used normally. The extrusion structure can drive the extrusion teeth 8 to rotate inside the diversion shell 4, crushing the blood clots in the diversion hoses 3 and preventing blockage. In summary, the diversion of the four diversion hoses 3, combined with the crushing of blood clots, makes the anti-blockage effect better.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
