Description

Technical Field

[0001] This utility model relates to the field of medical gas filling, and in particular to a medical gas filling device that prevents tipping. Background Technology

[0002] Medical gases are gases used in medical environments for treatment, diagnosis, anesthesia, or to power medical equipment. For example, oxygen is used to treat patients with hypoxia, carbon dioxide is used in laparoscopic surgery or for respiratory stimulation, and nitric oxide is used to treat persistent pulmonary hypertension in newborns and to dilate pulmonary blood vessels. Hospitals typically supply these gases centrally via pipelines or cylinders. Since medical gases are consumables, the gas stored in cylinders needs to be refilled. During storage, the cylinders must be secured to prevent collisions, slippage, and damage to components. Therefore, there is an urgent need for an anti-tipping medical gas filling device to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing an anti-tipping medical gas filling device that can fix the cylinder body during filling, prevent the cylinder from tipping over, and avoid damage to parts caused by collision and rolling.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tilt-resistant medical gas filling device includes a base and a placement plate. Support feet are provided at the four corners of the bottom surface of the placement plate, and the support feet are fixedly connected to the base. An anti-tilt plate is fixedly connected to one side of the top surface of the placement plate. A clamping mechanism is provided on the placement plate. The clamping mechanism includes two fixing blocks fixedly connected to the upper end of the placement plate, and the two fixing blocks are respectively arranged at two corners on the other side of the top surface of the placement plate. A fixing rod is fixedly connected between the two fixing blocks and between the fixing blocks and the anti-tilt plate. A clamping assembly is rotatably sleeved on the fixing rod. The clamping assembly is used to clamp the bottom of the gas cylinder. A torsion spring is installed between the fixing rod and the clamping assembly. One end of the torsion spring is fixedly connected to one of the fixing blocks, and the other end is fixedly connected to the inner wall of the clamping assembly. A linkage plate is installed below the placement plate, and three linkage rods are hinged to the periphery of the linkage plate. The three linkage rods are respectively hinged to three clamping assemblies, and a pedal is fixedly connected to the bottom surface of the linkage plate. A locking mechanism and an inflation tube are installed on the anti-tilt plate. The locking mechanism is used to lock the top of the gas cylinder, and the inflation tube is fixedly connected to the top of the anti-tilt plate. One end of the inflation tube is connected to the inflation head, and the other end is connected to an external inflation device. By using the clamping mechanism and the locking mechanism together, the cylinder body can be fixed during the inflation of the medical gas cylinder to prevent the cylinder from tipping over.

[0006] The clamping assembly includes a hollow cylindrical rod and a clamping block. The two ends of the hollow cylindrical rod located between the two fixed blocks are rotatably connected to the two fixed blocks respectively, while the two ends of the hollow cylindrical rod located between the fixed block and the anti-tilt plate are rotatably connected to the fixed block and the anti-tilt plate respectively. The other end of the torsion spring is fixedly connected to the inner wall of the hollow cylindrical rod, and the clamping block is fixedly connected to the middle of the hollow cylindrical rod.

[0007] The locking mechanism includes a through groove located near the top of the anti-tilt plate, extending along the width of the anti-tilt plate. A movable rod is movably mounted within the through groove, with two symmetrically arranged semi-circular rings rotatably connected to both ends of the movable rod. The other ends of the two semi-circular rings are provided with opposing semi-cylindrical threaded portions, which are threadedly connected to the same knob block. The two semi-circular rings are secured to the gas cylinder by rotating the knob block.

[0008] The anti-tilt plate has a bonding plate on the side facing the gas cylinder. The bonding plate has an arc-shaped structure on the side close to the gas cylinder, so that the gas cylinder can be placed tightly against the bonding plate.

[0009] The top surface of the placement plate is provided with a placement groove to facilitate the placement and positioning of the gas cylinder.

[0010] By adopting the above technical solution, this utility model has the following beneficial effects:

[0011] This utility model adopts a double locking structure design. The two semi-circular rings controlled by the knob block in the locking mechanism quickly lock and release the top of the gas cylinder. In addition, the three sets of clamping components driven by the pedal form a circumferential constraint on the lower end of the gas cylinder, which realizes the fixation of the top and bottom of the gas cylinder. This keeps the gas cylinder in a vertical and stable state during the inflation process, effectively preventing the gas cylinder from tipping over and avoiding collisions and rolling that could cause damage to parts.

Detailed Implementation

[0015] See Figures 1-2An anti-tipping medical gas filling device includes a base 1 and a placement plate 2. The top surface of the placement plate 2 is provided with a placement groove 21 for easy placement and positioning of the gas cylinder. Support feet 6 are provided at the four corners of the bottom surface of the placement plate 2, and the support feet 6 are fixedly connected to the base 1. The base 1 is made of a circular plate to improve the stability of the device. An anti-tipping plate 3 is fixedly connected to one side of the top surface of the placement plate 2. An adhesive plate 31 is provided on the side of the anti-tipping plate 3 facing the gas cylinder. The adhesive plate 31 can be made of rubber, and its side near the gas cylinder has an arc-shaped structure to fit the body of the gas cylinder. A clamping mechanism 4 is provided on the placement plate 2 to clamp the bottom of the gas cylinder. A locking mechanism 5 and an inflation tube 7 are provided on the anti-tilt plate 3. The locking mechanism 5 is used to lock the top of the gas cylinder. The inflation tube 7 is fixedly connected to the top of the anti-tilt plate 3. One end of the inflation tube 7 is connected to the inflation head 8, and the other end of the inflation tube 7 is connected to an external inflation device. Since there are many types of inflation devices available and they are all existing technologies, this utility model does not limit or describe them.

[0016] The clamping mechanism 4 includes two fixing blocks 41 fixedly connected to the upper end of the placement plate 2, and the two fixing blocks 41 are respectively arranged at the two corners on the other side of the top surface of the placement plate 2. Fixing rods 42 are fixedly connected between the two fixing blocks 41 and between the fixing blocks 41 and the anti-tilt plate 3, that is, there are three fixing rods 42 arranged vertically in pairs and forming a quadrilateral structure with the anti-tilt plate 3. Each of the three fixing rods 42 is rotatably sleeved with a clamping assembly 43. The clamping assembly 43 specifically includes a hollow cylindrical rod 431 and a clamping block 432. The two ends of the hollow cylindrical rod 431 located between the two fixing blocks 41 are rotatably connected to the two fixing blocks 41 respectively, and the two ends of the hollow cylindrical rod 431 located between the fixing blocks 41 and the anti-tilt plate 3 are rotatably connected to the fixing blocks 41 and the anti-tilt plate 3 respectively. The clamping block 432 is fixedly connected to the middle part of the hollow cylindrical rod 431. A torsion spring 44 is provided between the fixed rod 42 and the clamping assembly 43, and the torsion spring 44 is sleeved on the fixed rod 42. One end of the torsion spring 44 is fixedly connected to one of the fixed blocks 41, and the other end is fixedly connected to the inner wall of the hollow cylindrical rod 431. A triangular linkage plate 45 is provided below the placement plate 2. Three linkage rods 46 are hinged to the triangular part of the periphery of the linkage plate 45. The other ends of the three linkage rods 46 are respectively hinged to the three clamping blocks 432. An L-shaped plate-shaped pedal 47 is fixedly connected to the bottom surface of the linkage plate 45.

[0017] In use, the user presses down on the pedal 47, which causes the linkage plate 45 to move horizontally downward, thereby causing the three linkage rods 46 to move downward. The linkage rods 46 pull the clamping block 432 and the hollow cylindrical rod 431 to rotate around the fixed rod 42 as the rotation axis, causing the three clamping components 43 to unfold outward. Then, after the gas cylinder is placed in the positioning groove 21 of the placement plate 2, the user releases the pedal 47. The torsion spring 44 returns to its original position and applies a rotational force to the hollow cylindrical rod 431 facing the gas cylinder, thereby causing the three clamping blocks 432 to clamp the gas cylinder around its periphery. Preferably, the contact surface between the clamping block 432 and the gas cylinder is made with an arc surface that is adapted to the cylinder body, so that the gas cylinder is more tightly fixed.

[0018] The locking mechanism 5 includes a through groove 51 located near the top of the anti-tilt plate 3, extending along the width of the anti-tilt plate 3. A movable rod 52 is vertically movable within the through groove 51. Two symmetrically arranged semicircular rings 53 are rotatably connected to both ends of the movable rod 52. The two semicircular rings 53 are made of elastic metal sheets to ensure elastic deformation under stress. The two semicircular rings 53 can jointly clamp the gas cylinder for fixation. The other ends of the two semicircular rings 53 are provided with opposing semi-cylindrical threaded portions 54. These two semi-cylindrical threaded portions 54 combine to form a cylindrical structure with threads. A knob block 55 is connected to the external thread of the cylindrical structure. By controlling the distance the knob block 55 is screwed into the cylindrical structure, the opening and closing size of the two semicircular rings 53 is controlled, thereby controlling the locking force at the top of the gas cylinder.

[0019] This invention involves placing the gas cylinder on the placement plate 2 so that one side of the gas cylinder is tightly fitted to the fitting plate 31. Then, the upper and lower parts of the gas cylinder are clamped and fixed by the locking mechanism 5 and the clamping mechanism 4. After that, the inflation head 8 is connected to the input end of the gas cylinder, the inflation tube 7 is connected to the external inflation device and inflation begins. After inflation is completed, the inflation device is turned off, the inflation head 8 is removed, and the knob block 55 is turned outward to control the two semi-circular rings 53 to release the clamping of the upper part of the gas cylinder. The two semi-circular rings 53 are pulled upward to rotate them to the back of the anti-tilt plate 3 for the next use. Then, the pedal 47 is pressed to make the clamping assembly 43 move outward to release the clamped gas cylinder. After the gas cylinder is taken out, the pedal 47 is released to complete the gas cylinder inflation operation.
