Description

Technical Field

[0001] The utility model relates to the technical field of medical catheter auxiliary equipment, in particular to a cardiac intervention catheter nursing fixer. Background Art

[0002] Cardiac interventional surgery is a new technology for diagnosing and treating cardiovascular diseases. It is a diagnostic and treatment method that punctures surface blood vessels and inserts a cardiac catheter under continuous projection of digital subtraction. It uses specific cardiac catheter operation techniques to diagnose and treat heart disease. After the catheter is inserted into the patient's body, it needs to be cared for and fixed. The existing fixation methods are usually Velcro and rope binding. Both methods have certain defects and cannot position the catheter well. The former Velcro is usually attached to the patient's body surface. On the one hand, it is inconvenient to adjust and reposition the catheter. On the other hand, long-term sticking can easily aggravate the patient's discomfort. The latter cannot be squeezed by force, so the rope cannot be tied too tightly, which makes the catheter easy to loosen, and then causes the catheter to fall off the patient's body. The catheter needs to be observed in time, which is more troublesome. For this reason, we propose a cardiac interventional catheter care fixator. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1-8 The utility model provides a technical solution: a cardiac intervention catheter nursing fixator, including a support frame 1, and also includes:

[0030] A C-shaped tube 2, wherein the C-shaped tube 2 is slidably disposed on the support frame 1, and the open end of the C-shaped tube 2 faces one side, and a catheter is placed in the C-shaped tube 2;

[0031] A deflection rod 3, the deflection rod 3 is rotatably connected to the C-shaped tube 2;

[0032] The rotating assembly 4 is arranged on the support frame 1, and the deflection rod 3 is deflected. The C-shaped tube 2 is driven to slide through the rotating assembly 4, and the open end of the C-shaped tube 2 is directed toward the support frame 1, so as to position the catheter. Specifically, the rotating assembly 4 includes an axis 41 fixedly arranged on the C-shaped tube 2, and a telescopic rod 42 is arranged between the axis 41 and the support frame 1, and the two ends of the telescopic rod 42 are respectively rotatably connected with the axis 41 and the support frame 1, and a tension spring 43 is arranged in the telescopic rod 42, and the two ends of the tension spring 43 are respectively fixedly connected with the two ends of the telescopic rod 42, and a sliding block 44 is rotatably arranged on one end of the opening of the C-shaped tube 2, and a slide groove 45 is provided on the support frame 1, and a sliding block 44 slides in the slide groove 45;

[0033] The deflection rod 3 includes a rod 1 5 rotatably disposed on the shaft 1 41, the other end of the rod 1 5 contacts and abuts against the support frame 1, a rod 2 51 is fixedly connected to the rod 1 5, the rod 2 51 is also rotatably disposed on the shaft 1 41, and a handle 52 is disposed on the rod 2 51;

[0034] Put the catheter into the open end of the C-tube 2, pull the handle 52, drive the rod 2 51 to deflect, and then drive the rod 1 5 to deflect. Because the other end of the rod 1 5 is in contact with the support frame 1, the rod 1 5 deflects and presses against the support frame 1, thereby deflecting the shaft 1 41. Due to the cooperation between the sliding block 44 and the sliding groove 45, the C-tube 2 slides on the support frame 1. Due to the cooperation between the telescopic rod 42 and the tension spring 43, while the C-tube 2 slides, the open end of the C-tube 2 gradually deflects downward, and then pull the handle 52 until the open end of the C-tube 2 faces the support frame 1, and the support frame 1 completely covers the open end of the C-tube 2. At this time, the positioning of the catheter can be completed.

[0035] An insertion block 6 is fixedly installed on one end of the opening of the C-shaped tube 2, and a groove 61 is opened on the insertion block 6. A fixing block 62 is slidably arranged on the support frame 1, and a spring 63 is arranged on the fixing block 62. The two ends of the spring 63 are respectively fixedly connected to the fixing block 62 and the support frame 1. The fixing block 62 slides in the groove 61, and a rope 64 is installed on the fixing block 62. The shapes of the insertion block 6 and the fixing block 62 are both triangular, which is convenient for sliding, inserting and fixing, so as to position the C-shaped tube 2;

[0036] When the open end of the C-tube 2 is facing the appropriate position, the insertion block 6 presses against the fixing block 62, forcing the fixing block 62 to slide and squeeze the spring 63. After the insertion block 6 slides for a certain distance, the fixing block 62 pops out and slides into the groove 61 under the elastic force of the spring 63, thereby completing the fixation of the C-tube 2. When the catheter needs to be adjusted, the rope 64 is pulled to drive the fixing block 62 to slide so that the fixing block 62 is separated from the groove 61, so that the C-tube 2 can be opened, and then the position of the C-tube 2 can be adjusted.

[0037] The support frame 1 includes a U-shaped block 7, which is located on the guardrail. The U-shaped block 7 is connected to a bolt 71 by threaded rotation, and multiple bolts 71 are provided to fix the support frame 1. The open end of the U-shaped block 7 is inserted into the guardrail on the patient's bed, and the open end of the U-shaped block 7 is fastened by the bolt 71 to complete the positioning of the support frame 1.

[0038] The C-tube 2 is made of a flexible elastic material, such as rubber. Since the catheter cannot be squeezed, placing the catheter into the C-tube 2 reduces the possibility of the catheter being squeezed, thereby reducing hard contact with the catheter.

[0039] Example 2

[0040] See also Figure 1-10 The utility model provides a technical solution: a cardiac intervention catheter care fixator, and embodiment 2 is optimized based on embodiment 1.

[0041] The rod 1 5 is rotatably connected to the rod 2 51, and there is damping between the rod 1 5 and the rod 2 51. A stopper 8 is fixedly arranged on the rod 1 5, and the stopper 8 contacts and abuts against the rod 2 51 to accommodate the rod 2 51. When the rod 1 5 is deflected, it abuts against the stopper 8, thereby driving the rod 2 51 to deflect. After the C-shaped tube 2 is deflected and fixed, the rod 2 51 deflects back in the opposite direction. On the one hand, the rod 2 51 is accommodated to save space. On the other hand, the rod 2 51 can press the catheter after it is deflected back in the opposite direction, thereby further limiting the catheter.
