Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a rotating tube used for preventing a negative pressure drainage tube from being compressed. Background Art
[0002] Drainage tubes are generally used for surgical drainage, that is, the pus, blood, fluid, etc. accumulated between human tissues or in the human body cavity are drained out of the body through the drainage tubes. Especially in vascular surgery, after vascular surgery, if the pus, blood, fluid, etc. accumulated between human tissues or in the human body cavity are not drained out of the body in time, it may cause postoperative infection or affect wound healing, causing inconvenience to the patient's later wound recovery.
[0003] The section of the drainage tube that is connected to the negative pressure machine is directly exposed to the outside and is most susceptible to squeezing. If the patient turns over, the drainage tube may be easily squeezed. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention aims to provide a rotating tube for preventing pressure on a negative pressure drainage tube, which can retract the drainage tube exposed to the outside into the rotating tube body, thereby preventing the drainage tube from being compressed.
[0005] The purpose of this disclosure can be achieved through the following technical solutions:
[0006] A rotating tube for preventing pressure on a negative pressure drainage tube, comprising:
[0007] A rotating tube body, wherein the inner side surface of the rotating tube body is provided with an internal thread, and the two ends of the rotating tube body are rotatably connected with a first connecting part and a second connecting part respectively, a first hole is opened on the first connecting part, a second hole is opened on the second connecting part, and a guide rod is fixedly connected between the first connecting part and the second connecting part;
[0008] A connector, which is disposed in the rotating tube body and is slidably connected to the guide rod, a peripheral side of the connector is provided with an external thread that is threadedly connected to the internal thread inside the rotating tube body, and a third hole is provided on the connector;
[0009] A bellows, one end of which is fixedly connected to the connector, and the other end of which is fixedly connected to the first connecting portion.
[0010] The above technical solution, its principle and technical effect:
[0011] The second connection part is fixedly connected to the negative pressure joint of the negative pressure machine, the drainage pipe joint is connected to the third hole on the connection head through the first hole, and the rotating tube body is rotated to make the connection head move toward the second connection part along the guide rod. The bellows contracts, so that the drainage pipe enters the rotating rotating tube body, which plays a role in preventing pressure on the drainage pipe. At the same time, the drainage waste enters the negative pressure machine through the bellows.
[0012] In a preferred example, the utility model can be further configured as follows: the first connecting portion includes a first connecting plate, the first hole is opened on the first connecting plate, the side of the first connecting plate is fixedly connected with a first connecting tube, and the first connecting tube is rotatably connected to the inner side of the rotating tube body.
[0013] In a preferred example, the present invention can be further configured as follows: a connecting joint is fixedly connected to a side surface of the connecting head close to the first connecting portion.
[0014] In a preferred example, the present invention can be further configured as follows: the connecting joint is communicated with the third hole.
[0015] In a preferred example, the present invention can be further configured as follows: the inner diameter of the first hole is larger than the outer diameter of the connecting joint.
[0016] In a preferred example, the utility model can be further configured as follows: the interior of the bellows is communicated with the third hole and the second hole.
[0017] In a preferred example, the utility model can be further configured as follows: the second connecting portion includes a second connecting plate, the second hole is opened on the second connecting plate, the side surface of the second connecting plate is fixedly connected with a second connecting tube, and the second connecting tube is rotatably connected to the inner side of the rotating tube body.
[0018] In a preferred example, the present invention can be further configured as follows: a plurality of connection holes are opened on the peripheral side of the second connection plate.
[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:
[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.
[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.
[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).
[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).
[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.
[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.
[0026] Beneficial effects of the present disclosure:
[0027] The drainage tube exposed outside can be put into the rotating tube body, which plays a role in preventing the drainage tube from being pressed. BRIEF DESCRIPTION OF THE DRAWINGS
