Description

Technical Field

[0001] This utility model relates to human daily necessities, and more particularly to medical devices, specifically a foldable fixation stent for arteries and veins in the operating room. Background Technology

[0002] In complex surgeries, patients under general anesthesia require routine monitoring of arterial blood pressure and central venous pressure, necessitating pressure sensors positioned at the level of the heart. Current technology places these sensors horizontally on either side of the patient's head. However, intraoperative positioning, such as head-up or head-down, alters the heart's horizontal position. If the sensor's position isn't adjusted promptly, the readings will be inaccurate, affecting the anesthesiologist's judgment. Therefore, an improved technique is urgently needed to address these issues in existing technologies. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides a technical solution: an operating room arteriovenous folding fixation bracket, including a base 1, four sliders 2 and four folding support frames;

[0025] The base 1 has a T-shaped groove 3. One end of the base 1 is open and an end cap 12 is provided at the open end. The slider 2 can slide in through the open end, and the end cap 12 is provided to prevent the slider 2 from detaching from the T-shaped groove 3 of the base. A fixing frame 13 is provided on one side of the base 1, and the whole is fixed by bolts. The sliders 2 are all slidably connected to the T-shaped groove 3 of the base 1. Each slider 2 has a folding support frame on its upper surface. Each folding support frame includes a platform 6. The platform 6 is located at the top of the folding support frame. Each platform has a pipe fixing component 8 on its upper side.

[0026] Each slider 2 has two first connecting sleeves 4 on its upper surface; the two first connecting sleeves 4 are coaxial, and the bottom of the folding support frame is rotatably connected to the first connecting sleeves 4 through a damping pivot.

[0027] Each of the aforementioned folding support frames includes two or more support rod groups arranged vertically and horizontally. Each of the aforementioned support rod groups includes two support rods 5 arranged in parallel and spaced apart. Each of the two ends of each support rod 5 is provided with a second connecting sleeve 7. The two adjacent support rods 5 are rotatably connected through the second connecting sleeve 7 and the damping shaft. The support rod 5 at the bottom is also rotatably connected to the first connecting sleeve 4 through the second connecting sleeve 7 and the damping shaft. The support rod 5 at the top is also connected to the platform 6. One end of the platform 6 is bonded to the second connecting sleeve 7 of the top support rod 5 to realize the connection between the platform 6 and the second connecting sleeve 7 of the corresponding support rod 5.

[0028] The damping shaft includes a central rod 9, a nut 10 and a washer 11. The two ends of the central rod 9 pass through the second connecting sleeves 7 of the corresponding support rods 5. The two ends of the central rod 9 are respectively provided with threads. The ends of the central rod 9 and the two ends of the second connecting sleeves 7 of the two interconnected support rods 5 are provided with nuts 10 through the washer 11.

[0029] like Figure 5 As shown, the pipe fixing assembly 8 includes a fixing seat 801, a movable pressure cap 802, a male buckle 803, and a female buckle 804. The fixing seat 801 is fastened to the platform 6 by bolts. One side of the fixing seat 801 is connected to one side of the movable pressure cap 802 by a hinge 805. The male buckle 803 is provided on the side of the fixing seat 801 away from the hinge 805, and the female buckle 804 is provided on the side of the movable pressure cap 802 away from the hinge 805. The female buckle 804 and the male buckle 803 cooperate with each other. The movable pressure cap 802 can be flexibly opened and closed by the cooperation of the female buckle 804 and the male buckle 803. This structure and method realize the limiting of one end of the pipe fixing assembly 8.

[0030] Installation method and operating principle: First, the two support rods 5 correspond to the first connecting sleeve 4 on the upper surface of the slide block via the second connecting sleeve 7, and are connected to each other via a damping shaft. The damping shaft is installed by passing the central shaft through the second connecting sleeve 7 and the first connecting sleeve 4 on one side, and simultaneously placing two sets of nuts 10 and washers 11 on the central shaft. Then, the central shaft is passed through the second connecting sleeve 7 and the first connecting sleeve 4 on the other side, and the two sets of nuts 10 and washers 11 are placed on the outer end of the central shaft, completing the installation of the damping shaft. Subsequently, the support rods 5 are connected to each other via the damping shaft until the support rod 5 connected to the platform 6 is installed on top. Finally, the pipe fixing assembly 8 is installed on the upper surface of the platform 6 with bolts, completing the assembly of the folding support frame and the slider 2. After assembling the connection structure of the four sets of folding support frames and slider 2, the slider 2 is inserted into the T-shaped groove 3 from one end of the base 1, and the end cap 12 is installed on the open end of the base 1 with bolts, completing the assembly. In use, first, firmly fix the base 1 to the head end of the operating table with bolts. The anesthesiologist will choose the left or right side of the patient for arterial and venous puncture and catheterization based on the different surgical methods and sites. According to the positions of the arterial pressure sensor, central venous pressure sensor, peripheral vein, and central venous catheters on either side of the patient's head, slide the four sliders 2 on the base 1 to their corresponding positions via the T-shaped grooves. The catheters are then fixed to the corresponding sliders 2 using the catheter fixing assembly 8. The four sliders 2 can be labeled to distinguish the catheters, or different colored sliders 2 can be used for differentiation. In the supine position, the four folding support frames are in their original folded horizontal position. Different catheters can be clearly distinguished by the labels or color markings on the sliders 2, ensuring the safety of various operations such as intravenous injection and arterial blood gas aspiration. If the patient's position is changed to head-up or head-down or feet-up during the operation, and the pressure sensor is not at the level of the patient's heart, the platform 6 can be adjusted higher or lower using the folding support frames to ensure that the pressure sensor on the platform 6 is always at the same level as the heart. Figure 6 As shown, this design ensures more accurate measurement of arterial and venous pressure values, safeguarding patient safety. The invention features a rational structure that effectively classifies and secures four lines of tubing: deep vein and peripheral venous infusion lines, and arterial and venous pressure sensors. The tubing fixing component 8 prevents slippage, and the folding support frame allows for easy adjustment of the pressure sensors' positions as the patient's posture changes during surgery, ensuring the sensors are at the same level as the heart. This guarantees accurate arterial and venous pressure monitoring during surgery and protects patient safety.
