Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a catheter fixing device for gastrointestinal abdominal wall hernia surgery. Background Art

[0002] The catheter fixing device for gastrointestinal abdominal wall hernia surgery is a device used to fix the catheter in gastrointestinal surgery.

[0003] In the related art, the catheter fixing device is usually placed outside the patient's body, and the catheter is passed through it to prevent the catheter from falling off or being pulled when the patient turns over or moves his body with a large amplitude while sleeping.

[0004] For example, a catheter fixing device for gastrointestinal abdominal wall hernia surgery with application number CN202121313162.2, in which the mounting block is tied tightly to the patient's body through a restraining component, and then the catheter is passed through the slot on the mounting block, and the catheter can be automatically clamped and fixed through the fixing component, thereby eliminating the need to manually compress the catheter and eliminating the need to stick the catheter to the patient's skin with tape, thereby improving the stability of catheter fixation, which not only improves safety but also improves the patient's comfort.

[0005] However, the above patent still has some problems in actual use. For example, when the mounting block is tied to the patient's body by the binding assembly, the mounting block will contact the patient's body and even squeeze the patient's skin. Although a sponge pad is provided on the mounting block, the patient will still feel uncomfortable when tying the mounting block. In addition, due to the fixing effect of the fixing block, after the catheter passes through the slot on the mounting block, when the patient pulls the catheter, the catheter will bend at the connection with the slot, causing the catheter to be squeezed and deformed at this location, affecting the use of the catheter. Summary of the invention

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The catheter fixing device for gastrointestinal abdominal wall hernia surgery according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the catheter fixing device for gastrointestinal abdominal wall hernia surgery of the embodiment of the utility model can reduce discomfort of wearing by allowing the adjustment sleeve 300 to be adjustably set on the outer ring of the strap 100 and rotatably setting the fixing device 400 on the adjustment sleeve 300, while allowing the other components to squeeze the patient's skin when the strap 100 is installed on the patient. In addition, the fixing device 400 can rotate with the catheter to reduce the squeezing of the catheter when the patient pulls the catheter, thereby reducing the situation that the use of the catheter is affected.

[0027] A catheter fixation device for gastrointestinal abdominal wall hernia surgery with application number CN202121313162.2 (hereinafter referred to as "the patent"), by respectively arranging the restraint components on both sides of the mounting block. When the restraint components are installed on the patient, the mounting block will squeeze the patient's skin, and dents will appear on the skin after long-term wearing, which will give the patient a poor user experience.

[0028] The catheter fixing device for gastrointestinal abdominal wall hernia surgery of the present invention is achieved by additionally providing a mounting frame 200 on the outer ring of the bandage 100, and adjusting the adjustment sleeve 300 to be adjustably set on the mounting frame 200. When the patient wears it, only the inner ring of the bandage 100 contacts the patient's skin, which will not cause squeezing of the patient's skin and will not form dents, thereby improving the patient's comfort.

[0029] The catheter fixing device for gastrointestinal abdominal wall hernia surgery of the utility model can adjust the adjustment sleeve 300 by squeezing the side plate 330 by the patient or other personnel to deform the arc-shaped side plate 330. Since the bottom plate 310 abuts against the outer circle of the binding belt 100, as the side plate 330 deforms, the top plate 320 is lifted, so that the clamping plate 340 is lifted along with the top plate 320 and detaches from the two adjacent limit blocks 201. Then, the adjustment sleeve 300 can be moved to the desired position. After reaching the desired position, the squeezing of the side plate 330 is released, so that the top plate 320 and the clamping plate 340 are reset, and the clamping plate 340 is re-limited between the two new adjacent limit blocks 201. The operation is faster and positioning adjustment can be achieved.

[0030] This patent uses a fixing component when fixing the catheter, that is, the starting motor drives the first bevel gear fixedly connected to its output end to rotate, and the first bevel gear drives the two sets of second bevel gears meshing with it to rotate in the opposite direction, and the two sets of second bevel gears drive the two sets of rotating rods on the two sets of box bodies to rotate. Since the moving block is not only slidably connected to the slide groove, but also threadedly connected to the rotating rod, the two sets of rotating rods will drive the two sets of moving blocks to move when they rotate, and then the two sets of clamping pads can be driven by the two sets of connecting rods to move closer to each other and against the tube wall of the catheter inside the slot, so as to fix the catheter inside the mounting block. This structure is relatively complicated, and since the mounting block cannot rotate, it is impossible to prevent the catheter from bending when the patient pulls the catheter.

[0031] The catheter fixing device for gastrointestinal abdominal wall hernia surgery of the present invention, by rotatably setting the mounting seat on the top plate 320 of the adjusting sleeve 300 and limiting the catheter by the clamping structure 430, can enable the fixing device 400 to rotate along with the pulling of the catheter when the patient pulls the catheter, thereby avoiding the situation where the catheter is squeezed and deformed at the connection of the fixing device 400, which affects the subsequent use of the catheter.

[0032] In addition, when fixing the catheter, the catheter fixing device for gastrointestinal abdominal wall hernia surgery of the utility model only needs to rotate the handle 433. The rotation of the handle 433 drives the threaded rod 432 to rotate, so that the threaded rod 432 rotates into the fixing ring 420, pushes the arc pressure plate 431 into the fixing ring 420, and cooperates with the inner wall of the fixing ring 420 to achieve clamping and fixing of both sides of the catheter, which is faster to operate and simpler in structure.

[0033] In summary, according to the catheter fixing device for gastrointestinal abdominal wall hernia surgery in the embodiment of the utility model, by setting the mounting frame on the outer ring of the strap and the adjusting sleeve being adjustably set on the mounting frame, it is possible to avoid squeezing the patient's skin by other components when the strap is installed on the patient, thereby reducing the patient's discomfort. In addition, through the rotatable fixing device, when the patient pulls the catheter, the fixing device can be rotated accordingly, thereby avoiding bending of the catheter and reducing extrusion and deformation of the catheter.
