Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an aspirator flushing joint. Background Art

[0002] During surgical operations, sterile saline is needed to flush the surgical area or instruments. At the same time, a suction device is needed to drain the bloody liquid, cell debris, and flushing water produced by the wound in a timely manner to clean the surgical field, make the surgical field clear, and reduce infection.

[0003] The existing flushing and suctioning device requires medical staff to coordinate the work with both hands, and due to the structural limitations of the flushing and suctioning device itself, the operation process is relatively long. In addition, the flushing and suctioning device is generally operated with the assistance of an assistant. If the hospital staff is tight and the doctor needs to operate it himself, the two-handed operation will cause the doctor to be unable to free his hands to perform other operations during the flushing operation. For this reason, an aspirator flushing connector is proposed. Utility Model Content

[0004] The utility model is a suction flushing joint proposed to solve the shortcomings in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an aspirator flushing connector, comprising a main body, a long thin tube fixedly passing through one side of the outer surface of the main body;

[0006] A chamber is formed inside the main body, and two rotating shafts are provided inside the chamber. The rotating shafts extend through the bottom wall of the chamber to the inside of the pipe of the main body, and the rotating shafts are sealed and rotatably connected to the main body. The outer surfaces of the two rotating shafts are fixedly sleeved with valve plates, and two sealing valve seats are fixedly installed on the inner walls of both sides of the pipe of the main body, and the two adjacent sealing valve seats match the valve plates on the same side.

[0007] Two gears are fixedly sleeved on the outer surfaces of the two rotating shafts, and the gears are located in the cavity;

[0008] Two limit assemblies are symmetrically installed inside the chamber, and the two limit assemblies are staggered up and down and connected to adjacent gears;

[0009] A first finger ring and a second finger ring are provided on one side of the outer surface of the main body. An L-shaped rack rod is installed between the first finger ring, the second finger ring and the chamber. The two L-shaped rack rods are staggered up and down and connected to adjacent gears, and the limit assembly matches the L-shaped rack rod.

[0010] Furthermore, both of the limiting assemblies include a first rack, and the first rack is meshed with the adjacent gear. One end of the first rack is fixedly connected to an L-shaped limiting rod. The rotation of the gear can drive the first rack to move, thereby driving the L-shaped limiting rod to move.

[0011] Furthermore, a slide rail is slidably connected to one side of the outer surface of the first rack, and the slide rail is fixedly connected to the chamber. The slide rail has a limiting effect on the first rack, which can ensure the stability of the movement of the first rack.

[0012] Furthermore, the two L-shaped rack rods include a baffle rod, and the baffle rod matches the L-shaped limit rod. A sliding rod is fixedly connected to one side of the outer surface of the baffle rod, and the sliding rod passes through the inner wall of the chamber and extends to the outside of the main body. The sliding rod and the main body are slidingly connected, and the main body pushes the sliding rod to have a limiting effect, which can ensure the stability of the sliding rod movement.

[0013] Furthermore, a second rack is fixedly embedded on one side of the outer surface of the slide rod, and the second rack is meshedly connected with the adjacent gear, so that the slide rod drives the gear to rotate.

[0014] Furthermore, sealing gaskets are fixedly installed on the top and bottom of the two valve plates, and the sealing gaskets are in sealing contact with the inner wall of the main pipe body to ensure the sealing between the valve plates and the main pipe body.

[0015] Furthermore, an aspirator connecting tube and an irrigator connecting tube are fixedly mounted on both sides of the outer surface of the main body. The aspirator connecting tube can be connected to an external aspirator, and the irrigator connecting tube can be connected to an external physiological saline supply device.

[0016] Beneficial effects of the utility model:

[0017] When the utility model is in use, the aspirator flushing connector adopts a double-finger-ring operation design through the long and thin tube, chamber, rotating shaft, main body, valve plate, sealing valve seat, gear, limit assembly, L-shaped rack rod, first finger ring and second finger ring. The flushing or suction can be controlled by one hand, and the flow rate can be controlled according to experience to improve the use effect. At the same time, the whole adopts a limit design. When the valve plate on one side is in an open state, the valve plate on the other side is in a state that cannot be opened, thereby avoiding the flushing and suction flow channels from communicating with each other, further improving the overall use effect.

A sealing gasket is also installed on one side of the outer surface of the sealing valve seat 16. When the valve plate 17 and the sealing valve seat 16 are closed, the sealing gasket can ensure the sealing of the connection between the valve plate 17 and the sealing valve seat 16.

[0027] Two gears 10 are fixedly sleeved on the outer surfaces of the two rotating shafts 13 , and the gears 10 are located in the chamber 15 . The two gears 10 are arranged up and down, and the distance between them is adjusted according to actual needs.

[0028] Two limit assemblies are symmetrically installed inside the chamber 15, and the two limit assemblies are staggered up and down and connected to adjacent gears 10. The two limit assemblies each include a first rack 14, and the first rack 14 is meshed with the adjacent gear 10. One end of the first rack 14 is fixedly connected to an L-shaped limit rod 11, and one side of the outer surface of the first rack 14 is slidably connected to a slide rail 9, and the slide rail 9 is fixedly connected to the chamber 15. After the rotating shaft 13 rotates, it can drive the gears 10 on both sides connected to it to rotate, and one of the gears 10 drives the first rack 14 connected to it to move, thereby driving the L-shaped limit rod 11 to move.

[0029] A first finger ring 6 and a second finger ring 3 are provided on one side of the outer surface of the main body 1.
