Description

Technical Field

[0001] The invention belongs to the technical field of outdoor medical care, and in particular relates to an outdoor self-anchoring catheter fixing frame. Background Art

[0002] Field training exercises are a type of combat simulation activity conducted by the military or emergency response teams in a natural environment, which aims to improve combat capabilities, survival skills and emergency medical assistance in complex environments. This type of training is usually conducted in areas such as mountains, jungles, and deserts that are far away from fixed medical facilities, and requires a high degree of self-sufficiency and rapid response mechanisms. Therefore, it is crucial to set up a complete medical support system outdoors to ensure that trainees can receive timely and effective treatment when they encounter accidental injuries. In the process of nursing treatment, catheters and their connecting devices (such as infusion pumps, negative pressure drainage devices, etc.) play a vital role.

[0003] However, during the nursing treatment process, if the catheter and its connecting equipment are placed directly on the ground, the uneven ground or soft texture will cause the equipment to be unstable and prone to tipping or displacement. The tipping of the equipment may not only damage the expensive instrument, but also cause liquid leakage or catheter detachment, affecting normal operation and endangering patient safety. In addition, the outdoor ground often contains dust, bacteria or other pollutants, and direct contact may increase the risk of infection. Therefore, in the outdoor nursing treatment process, it is necessary to use a bracket to place and fix the catheter and its connecting equipment, but the existing brackets are mainly designed for indoor use and lack adaptability to complex outdoor terrain. Since the outdoor ground is mostly unstable surfaces such as soft soil, gravel, and grass, the traditional indoor catheter fixing bracket is difficult to provide stable support on soft or uneven ground, and it is very easy to shake or even tip over due to touch or ground vibration. Once the bracket shakes or tips over, the catheter and medical equipment connected to it may be pulled or even fall off, causing treatment interruption, blood reflux, increased risk of infection, and even secondary injury or life-threatening in severe cases. Summary of the invention

[0004] In view of the defects and problems of existing outdoor medical care, the present invention aims to provide a stable and convenient medical care catheter fixing frame, which is suitable for complex environments such as the wild, ensures the stable fixation of catheters and equipment, avoids treatment interruptions and safety hazards caused by unstable stents, and improves the efficiency of outdoor first aid and care.

Specific embodiments

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. Embodiment

[0027] This embodiment provides an outdoor self-anchoring catheter fixing frame, as Figure 1-8 shown, including a central column 1. A catheter platform 7 is fixedly installed at the top of the central column 1. The catheter platform is used to place the catheter and its connecting devices. A plurality of catheter clips are fixed on the catheter platform 7 for clamping the catheter to prevent the catheter from being pulled off the connected device when the patient turns over and moves the body; Three support legs 2 are evenly spaced along the circumferential direction on the outer side of the central column 1. The central column 1 is fixedly supported on the ground through the three support legs.

[0028] The central column 1 includes an outer support tube 11 connected to each support leg 2. An inner core column 12 is slidably installed vertically inside the outer support tube 11. The top end of the inner core column 12 is detachably connected to the catheter platform. A core column locking assembly 13 is arranged on the outer support tube in a matching manner for locking the inner core column 12 and the outer support tube 11 together. There are various types of the core column locking assembly 13. In this embodiment, the core column locking assembly 13 includes a locking bolt. A threaded hole communicating with the inside is arranged radially at the top of the outer ring surface of the outer support tube 11. The locking bolt is installed in the threaded hole in a matching manner, and a handle is fixedly installed on the bolt head of the locking bolt. The locking bolt can be driven to rotate and penetrate into the outer support tube 11 to press and fix the inner core column 12 and the outer support tube 11 together through the handle.

[0029] The support leg 2 includes a guide sleeve 3, a ground-breaking rod 4, a winding and traction assembly 5 and an expansion block 6. The guide sleeve is arranged parallel to the center column and is connected to the outer support tube 11 of the center column. There are many ways to connect the guide sleeve 3 and the outer support tube 11 of the center column. This embodiment adopts a foldable connection method. Specifically: like Figure 2 As shown, the outer ring surface of the outer support tube 11 is evenly spaced along the circumferential direction with three groups of parallel links, the parallel links correspond to the support legs one by one, the inner ends of the parallel links are hinged to the outer support tube, and the outer ends of the parallel links are hinged to the corresponding guide sleeves. A driving assembly connected to the bottom end of the inner core column 12 is provided below the outer support tube 11, and the driving assembly is connected to each parallel link. When the inner core column 12 drives the driving assembly to lift, the driving assembly will push the parallel links upward to drive each guide sleeve 3 to synchronously rotate and translate upward around the inner end of the corresponding parallel link.

[0030] The parallel connecting rod includes two connecting rods 14 arranged in parallel and spaced apart vertically, the outer ends of the connecting rods 14 are arranged to tilt downward and are hinged to the guide sleeve on the same side, the inner ends of the connecting rods are hinged to the outer support tube 11, the outer support tube 11 arranged in parallel and spaced apart are connected to the guide sleeve 2 through two connecting rods 14 arranged in parallel and spaced apart to form a parallelogram-shaped support leg fixing frame, the driving assembly includes a lifting seat 15 fixedly installed at the bottom of the inner core column, and a driving rod 16 is hinged on the lower connecting rod between the outer support tube 11 and the guide sleeve 3 in each set of parallel connecting rods, and the driving rod 16 The tail end is hinged to the lifting seat 15. When the inner core column 12 drives the lifting seat 15 to rise, the lifting seat 15 will push the supporting leg fixing frame through each driving rod 16 to flip upward around the inner end of the parallel connecting rod and unfold. Conversely, when the inner core column 12 drives the lifting seat 15 to descend, the lifting seat 15 will pull the supporting leg fixing frame through each driving rod 16 to flip downward around the inner end of the parallel connecting rod and fold it. In this way, the supporting legs can be folded close to the central column when not in use, reducing the overall volume and making it convenient to carry and transport. When needed, it can be quickly unfolded by pulling the inner core column, thereby improving the response speed and deployment efficiency.

[0031] The soil-breaking rod 4 is vertically inserted in the guide sleeve 3 and can slide up and down along the guide sleeve. The bottom end of the soil-breaking rod 4 is a sharp end for breaking the soil, and the guide sleeve is matched with a rod locking assembly 31, which is used to lock the soil-breaking rod 4 and the guide sleeve 3 together to make the soil-breaking rod 4 lose its sliding function. There are many types of rod locking assemblies 31. The structure of the rod locking assembly 31 in this embodiment is the same as the structure of the core column locking assembly 13. When not in use, the ground-breaking rod 4 is pulled upward to move the sharp end of the ground-breaking rod 4 into the guide sleeve 3, and the ground-breaking rod 4 and the guide sleeve 3 are locked together by the rod locking assembly 31, which can effectively avoid accidental contact with the sharp end of the ground-breaking rod 4. When in use, after the supporting legs are unfolded and placed on the ground, the ground-breaking rod 4 and the guide sleeve 3 are unlocked by the rod locking assembly 31, and then the top of the ground-breaking rod 4 is pressed down, and the bottom end of the ground-breaking rod 4 will pass through the guide sleeve and insert into the bottom surface, thereby stably supporting the fixed frame on the ground.

[0032] like Figure 4 As shown, the ground-breaking rod 4 includes an upper rod section 41 and a lower ground-breaking section 42. The lower ground-breaking section 42 is composed of four sub-rods 421 distributed in a field shape. The top of the sub-rod 421 is hinged to the bottom of the upper rod section. Specifically: An articulated plug 422 is matched with the top of the sub-pole 421 along the diagonal direction of the ground-breaking rod 4, and four articulated slots matching the articulated plug 422 are distributed in a field shape at the bottom of the upper insertion rod section 41, and the end of the articulated slot facing outward along the diagonal is open. The articulated plug 422 is matched and installed in the corresponding articulated slot through an articulated axis. In a natural state, the four sub-pole naturally droops, contacts each other laterally, and gathers together to form a complete rod section, which is convenient for insertion into the soil.

[0033] like Figure 3 As shown, a receiving cavity 423 is vertically provided in the middle of the lower ground-breaking section 42, and an arc-shaped notch groove is vertically provided at the inner top corner end of each sub-rod 421. When the four sub-rods hang down and contact each other laterally and are gathered together to form a complete rod section, the arc-shaped notches of the four sub-rods are pieced together to form the receiving cavity 423. The cavity top of the receiving cavity 423 is conical, and the expansion block 6 is vertically slidably installed in the receiving cavity 423.

[0034] The coiling and traction assembly 5 includes a rope wheel shaft 51, a rope wheel 52, a driven gear 53, a driving rack 54, and a traction rope 55. The rope wheel shaft 51 is rotatably installed on the upper insertion rod section above the guide sleeve. The rope wheel 52 and the driven gear 53 are fixedly sleeved on the rope wheel shaft. The driving rack 54 is vertically fixed to the top of the guide sleeve below the driven gear, and the driving rack 54 is located between the driven gear 53 and the soil-breaking insertion rod 4. When the driven gear moves down with the soil-breaking insertion rod and passes by the driving rack 54, the driven gear 53 meshes with the driving rack 54; that is, after the lower soil-breaking section extends out of the guide sleeve by a fixed length, the driven gear meshes with the driving gear. The fixed length that the lower soil-breaking section extends out of the guide sleeve is greater than the length of the lower soil-breaking section. For example, in this embodiment, the length of the lower soil-breaking section is 35 cm, and the fixed length that the lower soil-breaking section extends out of the guide sleeve is 50 cm.

[0035] As Figure 8 shown, the head end of the traction rope 55 is fixed to the rope wheel, and the tail end of the traction rope 55 is coaxially connected to the top end of the expansion block. Specifically: a traction rope hole 412 communicating with the accommodation cavity is vertically provided in the middle of the upper insertion rod section. The top hole of the traction rope hole 412 is located on the side wall of the upper insertion rod section inside the rope wheel. The tail end of the traction rope 55 extends into the accommodation cavity through the traction rope hole and is coaxially connected to the top end of the expansion block. When pressing down the top end of the soil-breaking insertion rod to drive the lower soil-breaking section of the soil-breaking insertion rod to extend out of the guide sleeve and completely insert into the soil to a fixed depth, the driven gear meshes with the driving gear. As the soil-breaking insertion rod continues to be inserted downward, the driven gear will drive the rope wheel to rotate and wind up the traction rope during the process of moving downward along the driving rack, thereby driving the expansion block to move upward and push against the top of the accommodation cavity, driving the four sub-rods distributed in a cross shape to rotate and expand in a scattered manner around the top end to form an anchor. When in use, when the guide sleeve and the connected soil-breaking insertion rod expand outward, a wider base support surface can be formed. This structure increases the contact area between the entire fixing frame and the ground, thereby improving the overall stability and anti-overturning ability. Especially after the sub-rods expand to form a larger support area, it effectively prevents tilting or sinking caused by soft ground or vibration.

[0036] Furthermore, in this embodiment, the inner core column is a telescopic sleeve rod. The telescopic end of the inner core column is arranged upward and is fixedly connected to the conduit platform, so that the height of the conduit platform can be adjusted according to actual needs during use.

[0037] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
