Description

Bedside negative pressure connector

Technical Field

The utility model relates to the technical field of medical equipment, especially relate to a bedside negative pressure attach fitting.

Background

The bedside negative pressure connecting joint generally refers to a connecting channel used between a bedside continuous negative pressure suction tube and a plasma drainage tube, and can effectively keep continuous negative pressure suction and drain oozing blood and oozing liquid in a wound cavity.

However, the existing bedside negative pressure connecting joint still has the defects in use: the existing bedside negative pressure connecting joint mostly adopts a glass joint to connect all pipelines, the joint is inconvenient for a patient to get off the bed, and the drainage pipeline is not completely closed after getting off the bed, so that infection is easily caused. And the two ends of the glass joint are sharper and smaller, and the pipeline is easy to be blocked when the drainage liquid is viscous.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem among the prior art, the utility model provides a bedside negative pressure attach fitting has solved the bedside negative pressure attach fitting among the prior art and has caused the problem of infection easily when patient gets out of bed the activity.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:

the utility model provides a bed side negative pressure attach fitting, it includes transparent body, and the both ends of body are provided with the connector, and the middle part of body has the dwang along radially pegging graft, and the dwang is located the one end of body and is fixed with the valve plate that corresponds with the body hole, is fixed with sealed the pad on the fitting surface of valve plate and body hole.

Furthermore, a rotating handle is vertically fixed at one end of the rotating rod, which is positioned outside the tube body. The rotating handle is convenient to hold when the rotating rod rotates, and the convenience of operation is improved.

Furthermore, the rotating rod is in clearance fit with the pipe wall of the pipe body, and a rubber sealing ring is arranged between the rotating rod and the pipe wall of the pipe body. The clearance between dwang and the pipe wall is sealed through rubber seal, improves the leakproofness and the security of this joint.

Further, the valve plate is a circular plate, and the sealing gasket is fixed on the outer cylindrical surface of the valve plate. The circular plate is contacted with the inner hole wall of the tube body and is sealed by the sealing gasket on the outer cylindrical surface, so that the human tissue fluid is prevented from flowing out of the negative pressure tube, and the external bacteria and dust are prevented from entering the wound cavity of the patient to cause infection.

Further, the rotating rod is fixed on a diameter line of the valve plate. When the valve plate is opened or closed, the valve plate rotates around the central axis, so that the valve plate can be switched to an opening or closing state under a small rotation angle regardless of forward rotation or reverse rotation, and the convenience of operation is improved.

Furthermore, the connector is the taper pipe portion for being fixed in the body both ends, is provided with on the taper pipe portion to be spiral winding and to the convex anti-skidding line of outside. The anti-skidding line can prevent that the negative pressure pipe of connecting from droing, and the anti-skidding line is the spiral winding, can make the negative pressure pipe remove to the major diameter end from the path end of taper pipe portion through rotating when connecting, reduces the operation degree of difficulty, improves the convenience of connecting.

Furthermore, the pipe body, the rotating rod and the valve plate are all made of plastics. The plastic is not easy to be broken, and the joint cannot be broken in the moving process of the patient getting out of the bed, so that the patient can move more freely and conveniently.

The utility model has the advantages that: connect and dismantle the convenience when connecting negative pressure pipe and drainage tube through the bedside negative pressure attach fitting in this scheme, in the activity process of patient getting out of bed, rotatory dwang drives behind the valve plate seal tube body hole, break away from this joint from the negative pressure pipe that is close to negative pressure production device one end, make this joint hang on the drainage tube that is located human one side, can prevent effectively that patient from polluting the surrounding environment at activity in-process body fluid outflow, also can prevent that the surrounding environment from causing the infection for patient's wound cavity simultaneously, the security has been improved.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

As shown in fig. 1, the bedside negative pressure connection joint comprises a transparent pipe body 1, two ends of the pipe body 1 are provided with connectors 2, the connectors 2 are taper pipe parts 21 fixed at two ends of the pipe body 1, the taper pipe parts 21 are provided with anti-slip threads 22 spirally wound and protruding outwards, and the anti-slip threads 22 are arc-shaped protrusions and are smoothly connected with the outer wall surface of the taper pipe parts 21.

As shown in fig. 2, a rotating rod 3 is inserted into the middle of the tube body 1 along a radial direction, a valve plate 4 corresponding to the inner hole 11 of the tube body is fixed at one end of the rotating rod 3 located in the tube body 1, and a sealing gasket 41 is fixed on a matching surface of the valve plate 4 and the inner hole 11 of the tube body. A rotating handle 5 is vertically fixed at one end of the rotating rod 3 outside the tube body 1. The dwang 3 and the pipe wall clearance fit of body 1 are provided with rubber seal 6 between the pipe wall of dwang 3 and body 1. The valve plate 4 is a circular plate, and the seal 41 is fixed to the outer cylindrical surface of the valve plate 4. The swivelling levers 3 are fixed on the diameter line of the valve plate 4.
