Description

Technical Field

[0001] The present invention relates to the technical field of drainage tube fixing devices, and particularly to an abdominal drainage tube fixing device. Background Art

[0002] An abdominal drainage tube is used for clinical surgical drainage, guiding pus, blood, and fluid accumulated in the abdominal cavity to the outside of the body, and is a medical device for preventing postoperative infection and promoting wound healing. After abdominal surgery, an abdominal drainage tube is usually indwelled to drain the fluid in the abdominal cavity. The indwelling of the abdominal drainage tube often causes displacement due to the patient's movements. Therefore, a drainage tube fixing member is required to fix the drainage tube. When the existing drainage tube fixing member is used, it usually uses a pipe clamp to clamp the drainage tube, and a sticking layer is provided at the bottom of the pipe clamp. After removing the release paper, the pipe clamp is stuck on the patient's body. However, the existing fixing method has the following defects: when the drainage tube is pulled, the pipe clamp will pull the skin around the drainage wound, resulting in secondary injuries such as tearing of the wound. Summary of the Invention

[0003] In view of the defect that after the abdominal drainage tube is fixed, the pulling force acts on the skin around the wound, causing the wound to be torn and the force on the wound is large and not conducive to recovery in the above background art, a technical solution for an abdominal drainage tube fixing device is provided.

[0004] It includes four petal-shaped pulling pieces arranged in a circular array. A drainage wound decompression member is provided on the outer surface of the front petal-shaped pulling piece, and drainage tube restricting members are provided on the top surfaces of the rear petal-shaped pulling piece and the left and right petal-shaped pulling pieces;

[0005] Each petal-shaped pulling piece includes a parallel plate, a vertical plate fixed to the inner side of the top surface of the parallel plate. Arc-shaped pieces are fixed to the outer surfaces of the rear vertical plate and the left and right vertical plates. Medical double-sided adhesives are adhered to the bottom surfaces of the parallel plates;

[0006] A plastic tightening strip passing through the inside of the arc-shaped piece is fixed to the left side of the outer surface of the front vertical plate, and a circular ring is fixed to the end of the plastic tightening strip;

[0007] The drainage tube restricting member includes a base fixed to the upper surface of the vertical plate, a square frame fixed to the top end of the base. A tie strap passes through the inside of the square frame. One end of the tie strap is fixed with a rectangular sleeve, and the other end of the tie strap passes through the inside of the rectangular sleeve. 20 - 30 silicone convex balls are fixed to the inner surface of the tie strap in a circular array; specifically, the drainage tube is passed through the inside of the tie strap, and a section of the tie strap passing through the rectangular sleeve is pulled. While tightening the tie strap, the silicone convex balls are brought into contact with the drainage tube, thereby binding the body of the drainage tube and playing a role in fixing the drainage tube.

[0008] The drainage wound decompression component includes a fixing plate fixed on the outer surfaces of the front and rear vertical plates, and two side plates fixed on the upper and lower surfaces of the fixing plate. On the left side of the mutually approaching surfaces of the side plates, a winding roller is rotatably connected, and a driven gear is fixedly connected to the top end of the winding roller; on the right side of the mutually approaching surfaces of the side plates, a rotating shaft is rotatably connected, and a driving gear meshing with the driven gear is fixedly connected to the outer circle of the rotating shaft. Specifically, after tearing off the release paper at the bottom of the medical double-sided tape, with the drainage wound as the center, the four parallel plates are adhered to the skin around the wound by the medical double-sided tape. Subsequently, the rocker and the crank are shaken, forcing the hollow shaft and the ratchet to rotate, thereby rotating the rotating shaft. After driving the driven gear by the driving gear, the winding roller winds up the plastic tightening strip, and further makes the four vertical plates approach each other, pulling the skin around the wound to gather towards the center, preventing the drainage tube from being pulled and tearing the wound.

[0009] A ratchet is sleeved on the top end of the rotating shaft, and a pawl engaging with the ratchet is rotatably connected to the upper surface of the top side plate. A hollow shaft is fixed to the top end of the ratchet, a rocker is connected to the top end of the hollow shaft, and a crank is rotatably connected to the end of the rocker.

[0011] In the technical solution of the above abdominal drainage tube fixing device, preferably: notches for inlaying and fixing the base are all opened on the top end surfaces of the vertical plates.

[0012] In the technical solution of the above abdominal drainage tube fixing device, preferably: through grooves for the plastic tightening strip to pass through are all opened inside the arc-shaped pieces, and the inner circle of the ring is fixedly connected to the outer circle surface of the winding roller.

[0013] In the technical solution of the above abdominal drainage tube fixing device, preferably: a number of equally spaced teeth are fixedly arranged on the inner side of the section of the tie strap passing through the inside of the rectangular sleeve, and a check tooth engaging with the teeth is fixed in the inner cavity of the rectangular sleeve.

[0014] In the technical solution of the above abdominal drainage tube fixing device, preferably: the inner side surface of the tie strap contacts the outer surface of the abdominal drainage tube, the silica gel convex balls are all in a hollow state, and fine holes for discharging the internal air are all arranged on the surfaces of the silica gel convex balls.

[0015] In the technical solution of the above abdominal drainage tube fixing device, preferably: a driven gear protection cover covering the driven gear is fixed on the upper surface on the right side of the top side plate.

[0016] In the technical solution of the above abdominal drainage tube fixing device, preferably: a torsion spring is fixed on the outer circumferential surface of the ratchet pawl, and the other end of the torsion spring is fixedly connected to the upper surface of the top side plate.

[0017] In the technical solution of the above abdominal drainage tube fixing device, preferably: the cross-section of the paragraph of the rotating shaft above the driving gear is regular hexagon, and the cross-section of the bottom end port of the hollow shaft is regular hexagon.

[0018] In the technical solution of the above abdominal drainage tube fixing device, preferably: a ratchet protective shell covering the ratchet wheel and the ratchet pawl is fixedly connected to the top surface of the top side plate, the hollow shaft penetrates above the ratchet protective shell, threads are provided on the paragraph of the hollow shaft above the ratchet protective shell and two nuts are screwed thereon, and the end of the rocker arm away from the crank is penetrated by the hollow shaft and is located between the two nuts.

[0019] As can be seen from the above technical solution, compared with the prior art, the abdominal drainage tube fixing device provided by the present invention has the following beneficial effects:

[0020] In the technical solution of the present invention, four groups of petal-shaped pulling pieces are adhered around the abdominal drainage tube wound. With the cooperation of the drainage wound decompression piece and the plastic tightening strip, the four groups of petal-shaped pulling pieces are forced to move closer to the center of the wound. By pulling the skin around the wound towards the center, the wound is prevented from being torn, reducing secondary damage to the wound. Moreover, drainage tube limiting pieces are arranged on the four groups of petal-shaped pulling pieces to limit abdominal drainage tubes with different diameters and prevent the abdominal drainage tube from pulling the wound due to being pulled.
