Description

Technical Field

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

[0002] In clinical interventional treatment, external catheters are usually placed at the wound site or inserted into the body to serve as drainage. Currently, the phenomenon of external catheters in patients with gastrointestinal diseases is relatively common during clinical treatment. It plays a very important role in the treatment process, and preventing the catheter from falling off is one of the most important requirements during nursing care. Currently, when fixing the catheter, medical tape is usually used to bond the catheter to the human body surface. If the patient sweats easily, the medical tape will easily become ineffective, and the medical tape is also easy to involve the patient's skin when it is torn off, which can easily cause discomfort to the patient.

[0003] Patent No. 2022232243098, an improved solution for existing technologies, discloses a catheter fixation device for gastrointestinal surgery, comprising a fixing plate with a sliding mechanism provided on one side of the fixing plate, a clamping mechanism provided on the movable end of the sliding mechanism, and multiple fixing mechanisms provided on the bottom end of the fixing plate; the clamping mechanism comprises an upper clamping plate and a lower clamping plate connected to the sliding mechanism, the inner sides of the upper and lower clamping plates being provided with multiple clamping grooves, and a telescopic mechanism being provided between the upper and lower clamping plates. This solution secures the device to one side of a bed using the fixing mechanism, and can secure multiple catheters using the clamping and telescopic mechanisms. Depending on the position where the patient needs to insert the tube, the sliding seat is pulled to move the clamping mechanism to a suitable position away from the patient. However, the above solution has some drawbacks. 1. The length of the fixing mechanism cannot be adjusted to the available length of the bedside or other equipment, which may result in the fixing mechanism being too long and unusable. 2. After the sliding seat is adjusted, it cannot be fixed. If someone accidentally touches the sliding seat and causes it to move, the catheter may be pulled out of the patient's wound or the wound may be pulled, which is very unsafe.

[0004] Therefore, in order to solve the above-described technical problems, a gastrointestinal surgical catheter fixing device is urgently needed. Utility Model Content

[0051] When the utility model is implemented,

[0052] When in use, the length of the retractable base and the retractable slide rod is adjusted according to the length of the installation position. After the adjustment, the first positioning bolt 404 is screwed so that the first positioning bolt 404 abuts against the right cylinder 402, thereby limiting the right cylinder 402 and fixing it to the adjusted position. After the adjustment, the U-shaped card is clamped on the bed frame or other fixed object, and then the second positioning bolt 502 is screwed to firmly fix the U-shaped card 501 on the bed frame or other fixed object; in this way, the entire retractable base can be stably installed in the desired position. When adjusting the position of the catheter fixing mechanism, the insertion rod 314 is slightly pulled out so that the clamping plate 315 does not abut against the limiting slide groove 200, and then the catheter fixing mechanism is pushed to move. After reaching the specified position, the insertion rod 314 is released. Under the action of the spring 313, the clamping plate 315 abuts against the limiting slide groove 200, thereby fixing the catheter fixing mechanism;

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0057] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0058] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0059] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0060] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
