Technical Field
[0001] This utility model relates to the field of medical supplies, specifically a surface catheter fixation device that is easy to adjust. Background Technology
[0002] A surface catheter fixation device is a medical device used to secure various surface catheters (such as venous catheters, arterial catheters, urinary catheters, and gastric tubes). Its main purpose is to ensure the catheter's stable position within the patient's body, preventing displacement or dislodgement, while minimizing patient discomfort. Surface catheter fixation devices play a crucial role in medical care, ensuring catheter stability and patient safety. Choosing an appropriate fixation device and using it correctly can effectively reduce complications and improve patient comfort and treatment outcomes.
[0003] In the existing technology, there are also some surface catheter fixation patches that can fix the catheter, but when using them, the direction of the catheter routing is fixed, and it is inconvenient to adjust when encountering some obstacles. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surface catheter fixation device that is easy to adjust. This catheter fixation device can adjust the direction of the catheter in real time according to the situation, reducing the workload of medical staff.

[0011] The card cover has a downwardly recessed mating cavity in the middle. A mating rod is provided in the middle of the mating cavity, and a central fixing hole is provided in the middle of the mating rod. The central fixing hole mates with a central fixing pin on the card seat. An inner mating platform is provided on the inner side of the mating cavity, and an outer mating platform is provided on the outer side of the mating cavity. The inner mating platform mates with the inner fixing platform on the card seat. A first fixing block and a second fixing block are provided on the outer mating platform. The first fixing block mates with a first fixing hole, and the second fixing block mates with a second fixing hole. An upwardly protruding first fixing rod is provided on the outer side of the outer mating platform. The first fixing rod mates with a first fixing groove.

[0012] Preferably, the fixed cavity and the mating cavity have a "Y" shaped structure.
[0013] Preferably, the card holder has two first fixing holes, and the card cover has two corresponding first fixing blocks.
[0014] Preferably, the space between the first fixing groove and the second fixing hole is a hollow structure.
[0015] Preferably, the fixed shaft is a locating pin.
[0016] Preferably, when the card holder and the card cover are mated, the partition rod in the middle of the fixed cavity and the mating rod in the middle of the mating cavity divide the upper part of the fixed cavity and the mating cavity into two channels.
[0017] Preferably, limit posts are provided in both the upper channels of the fixed cavity and the mating cavity.
[0018] The beneficial effects of this utility model are as follows: 1. A fixing shaft is provided on the fixing seat, and a fixing hole is provided in the middle of the card holder. Through the connection of the fixing shaft and the fixing hole, the card holder can rotate around the fixing shaft on the fixing seat. Thus, medical staff do not need to adjust the injection angle and catheter direction before injection. After the injection is completed, the card holder located on the fixing seat can be rotated. 2. Both the fixing cavity and the mating cavity are "Y" shaped structures. The upper part of the fixing cavity and the mating cavity are divided into two channels by the partition rod in the middle of the fixing cavity and the mating rod in the middle of the mating cavity. During use, the two branches of the Y-shaped catheter can be easily fixed. 3. Through the cooperation of multiple sets of fixing structures, the stability of the catheter in the fixing cavity and the mating cavity is ensured, and the catheter displacement or dislodgement is prevented.
