Description

Technical Field

[0001] The utility model relates to the relevant technical field of medical equipment, in particular to a disposable suction connecting tube. Background Art

[0002] Medical negative pressure aspirators are essential tools for surgical operations. The main components include the aspirator head, hose, and drainage bottle / bag. Its working principle is to generate negative pressure through a vacuum pump or other means. The atmospheric pressure pushes the effusion, blood accumulation, solid particles, etc. during the operation into the aspirator, thereby achieving a clear surgical field of view and reducing the chance of contamination. In orthopedic surgeries such as total hip and total knee replacements, a large number of solid particles such as bone fragments and debris of varying sizes may be generated due to surgical steps such as grinding the acetabulum, sawing bones, and removing soft tissues. These solid particles often cause the aspirator to become clogged, so the surgeon needs to find the cause of the blockage, clear the clogged area, or even replace the aspirator head or aspirator hose, which prolongs the operation time and increases the patient's bleeding and infection risk.

[0003] The Chinese patent publication number is CN220530413U, and the authorization announcement date is February 27, 2024. A medical suction tube with a connection protection structure disclosed includes a connection tube, one end of the connection tube is movably connected to a buckle kit, the buckle kit is movably connected to the connection tube and the flat-bottomed bolt through a U-shaped buckle, the other end of the connection tube is fixedly connected to a connection head, the lower outer side of the connection head is fixedly connected to a connection rope, and the top of the connection rope is fixedly connected to a connection cover, which can not only be quickly and easily installed, but also ensure the structural stability of the medical suction tube, prevent the displacement or fall off of the pipeline due to unstable connection during use, bring great convenience to the work of medical staff, so that the medical suction tube can be quickly picked up and used in an emergency, improve work efficiency, effectively prevent dust and bacteria in the air from entering the connection head, provide good adaptability to the use environment, reduce the requirements for the use environment, and expand the scope of application of this medical suction tube. The disadvantage of this utility model is that the tube is easily blocked, resulting in a long operation time, and the prolonged operation time will increase the patient's bleeding and infection risks. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art that the tube is easily clogged and the operation time is prolonged, thereby increasing the patient's bleeding volume and infection risk. The utility model provides a disposable suction connecting tube that is not easy to clog and reduces the operation time, thereby reducing the patient's bleeding volume and infection risk.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A disposable suction connecting tube comprises a suction connecting tube, wherein the suction connecting tube is provided with a tube tail and a suction head, wherein the tube tail is arranged at the upper end of the suction connecting tube, and the suction head is arranged at the lower end of the suction connecting tube, wherein the tube tail and the suction head are integrally formed with the suction connecting tube, wherein the interior of the tube tail is hollow and communicated with the interior of the suction connecting tube, wherein the interior of the suction head is hollow and communicated with the interior of the suction connecting tube, and wherein the outer diameter of the suction head is the same as the outer diameter of the suction connecting tube.

[0007] During installation, the suction connecting tube is connected to the suction device by installing the tube tail on the connecting tube of the suction device; in orthopedic surgeries such as total hip and total knee replacements, when there is fluid accumulation, blood accumulation, solid particles, etc., turn on the suction device and place the suction head on the fluid accumulation, blood accumulation, solid particles, etc. for suction. The suction head can block excessively large solid particles outside, so the suction connecting tube is not easy to be blocked, and the outer diameter of the suction head is the same as the outer diameter of the suction connecting tube, reducing the possibility of the suction head damaging the surgical site, thereby achieving the purpose of not being easy to be blocked and reducing the operation time, thereby reducing the patient's bleeding volume and infection risk.

[0008] Preferably, a filter screen is provided on the lower end of the suction head, the filter screen is placed at the lower end of the suction head and is formed integrally with the suction head, and the cross section of the lower end surface of the filter screen is arc-shaped. The arc-shaped structure can prevent the front end from being too sharp and irritating soft tissue.

[0009] Preferably, the distance between the lowermost end of the arc of the filter screen and the lower end surface of the suction head is 0.7-1 mm. The arc should not be too large, otherwise it will cause a decrease in the suction force.

[0010] Preferably, the filter screen is provided with a plurality of mesh holes, the mesh holes are triangular in shape, the mesh holes are evenly distributed on the filter screen with the arc-shaped lower end of the filter screen as the center, and the mesh holes are connected to the interior of the suction head. The mesh holes are triangular in shape, which is convenient for blocking oversized solid particles or blood clots.

[0011] Preferably, the inner diameter of the suction connection tube, the inner diameter of the tube tail and the inner diameter of the suction head are all the same. The same inner diameter facilitates the suction of liquids such as effusion and blood accumulation, and is not prone to blockage.

[0012] Preferably, the cross section of the tube tail is trapezoidal, and the long side of the trapezoidal tube tail is connected to the connecting suction tube. The cross section of the tube tail is trapezoidal for easy installation.

[0013] The beneficial effects of the utility model are: it is not easy to be blocked and the operation time is reduced, thereby reducing the patient's bleeding volume and infection risk; the arc-shaped structure can avoid the front end being too sharp and irritating the soft tissue; the arc is not easy to be too large, otherwise it will cause a decrease in attraction; the mesh is in a triangular shape, which is convenient for blocking overly large solid particles or blood clots; the same internal diameter is convenient for sucking away liquids such as effusions and blood, and it is not easy to be blocked; the cross-section of the tube tail is trapezoidal, which is convenient for installation.
