Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, and particularly relates to a fixing device for an ECMO transfer vehicle. Background Art

[0002] An artificial membrane lung, also known as ECMO (extracorporeal membrane oxygenation), is a kind of artificial heart-lung machine, mainly used for patients with severe cardiopulmonary failure. It provides continuous extracorporeal oxygenation and circulatory support for patients, reduces the cardiopulmonary burden of patients, and buys more treatment time for medical staff. ECMO mainly includes intravascular cannulas, connecting tubes, a power pump (artificial heart), an oxygenator (artificial lung), an oxygen supply tube, a monitoring system, etc.; the power pump (artificial heart) provides power to drive blood to flow in the pipeline; the oxygenator (artificial lung) oxygenates the input blood and outputs oxygenated arterial blood; the oxygenator is divided into two types: silicone membrane type and hollow fiber type; the silicone membrane type has good biocompatibility, less plasma leakage, and less damage to blood components, and is suitable for long-term use.

[0003] When transporting such patients, the transfer vehicle is relatively small, and the electrocardiogram monitor can only be placed on the patient; there are many instruments and no place to put them. During the transfer process, an electrocardiogram monitor and a micro-infusion pump are needed. For thin patients, it is okay to place them beside the patient, but for obese patients, they can only be placed on the patient. Such an operation not only affects the positioning and observation of the instruments during the transfer process, but also causes a certain degree of compression on the patient's body, resulting in discomfort for the patient. Some existing fixing frames are inconvenient to disassemble and assemble during use, and for some narrow places, they cannot be folded, resulting in inconvenient movement, which is not conducive to transporting patients multiple times and using during transfer. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a fixing device for an ECMO transfer vehicle, which effectively solves the problem of inconvenient fixing of instruments during the transportation of patients.

[0005] The technical solution it adopts is that the present utility model includes two main support plates that are opposite to each other left and right. The opposite ends of the two main support plates are respectively rotatably connected with connecting columns in the front-back axial direction. The front and rear ends of the connecting columns respectively penetrate through the main support plates and are fixed with support rods in the up-down direction. A rotating column in the front-back axial direction is arranged below the connecting columns. The front and rear ends of the two rotating columns are respectively rotatably connected with the corresponding support rods on their sides. A side support plate is fixed on the rotating column. Placing grooves with openings facing upwards are respectively formed on the main support plates and the side support plates. The placing grooves on the two main support plates are communicated with each other and can form a rectangle. The lower ends of multiple support rods are detachably connected with clamping devices. The clamping device includes an inverted U-shaped fixing block, and a clamping plate that can move up and down is arranged inside the fixing block.

[0006] The structure of the utility model is reasonable and easy to use, which is convenient for medical staff to place some life-sustaining instruments during the transfer of patients, avoiding the occupation of the patient's lying space when the instruments are placed on the transfer stretcher or transfer bed, and also avoiding the extra burden on the patient's body caused by placing the instruments on the patient. It is beneficial to the nursing operation of medical staff during the patient transfer process. At the same time, when not in use, only the support frame needs to be removed and the clamping device is retained, so that when used next time, the support frame can be quickly disassembled and assembled, and the main support plate and side support plate can be folded and placed, avoiding the excessive storage space caused by the idleness of the transfer tool and the inconvenience of its placement, and avoiding the reduction of the transfer efficiency of medical staff caused by repeated disassembly and assembly, which is beneficial for medical staff and patients to use.

[0013] The following further describes in detail the specific embodiments of the utility model with reference to the accompanying drawings.

[0014] It is given by Figures 1 to 6 and includes two main support plates 1 opposite to each other left and right. Connecting columns 2 in the front-back axial direction are respectively rotatably connected to the back ends of the two main support plates 1. The front and back ends of the connecting columns 2 respectively penetrate through the main support plates 1 and are fixed with support rods 3 in the up-down direction. A rotating column 4 in the front-back axial direction is arranged below the connecting columns 2. The front and back ends of the two rotating columns 4 are respectively rotatably connected to the support rods 3 on their corresponding sides. A side support plate 5 is fixed on the rotating column 4. Placing grooves 6 with openings facing upwards are respectively formed on the main support plates 1 and the side support plates 5. The placing grooves 6 on the two main support plates 1 communicate with each other and can form a rectangle. The lower ends of multiple support rods 3 are detachably connected with clamping devices. The clamping device includes an inverted U-shaped fixing block 7, and a clamping plate 8 that can move up and down is arranged in the fixing block 7.

[0015] For the convenience of using this device, inverted U-shaped main blocking rods 9 are respectively arranged below the two main supporting plates 1. The two main blocking rods are located inside the plurality of supporting rods 3, and their opposite ends are respectively fixedly connected to the corresponding supporting rods 3 on their corresponding sides. Side blocking rods 10 are respectively arranged below the two side supporting plates 5. The two side blocking rods 10 are located outside the plurality of supporting rods 3, and their opposite ends are fixedly connected to the corresponding supporting rods 3 on their corresponding sides.

[0016] For the convenience of fixing the instrument, an elastic damping pad 11 is arranged in the placement groove 6. A positioning belt 12 is fixedly connected to the upper end of the right main supporting plate 1, and a positioning ring 13 is fixedly connected to the upper end of the left main supporting plate 1. The positioning belt 12 can pass through the positioning ring 13.

[0017] For the convenience of using the positioning belt 12, a magic male fastener is arranged at the free end of the positioning belt 12, and a magic female fastener that can be adhered to the magic male fastener is arranged on one side of the positioning belt 12.

[0018] For the convenience of the detachable connection between the supporting rod 3 and the clamping device, a slot 14 that penetrates up and down is opened on the side of the fixed block 7 away from its notch. The supporting rod 3 can be inserted into the slot 14. An inverted L-shaped limiting groove 15 is opened on the supporting rod 3. The opening of the limiting groove 15 faces downward and the side away from the notch of the fixed block 7 communicates with the outside. A limiting rod 16 is slidably connected in the fixed block 7. The limiting rod 16 can move in the limiting groove 15 and can contact the stepped surface of the limiting groove 15.

[0019] For the convenience of the movement of the limiting rod 16, the side of the upper end surface of the limiting rod 16 close to the supporting rod 3 is an inclined surface that slopes downward. The supporting rod 3 can contact the inclined surface of the limiting rod 16 and can also contact the upper end surface of the limiting rod 16. The two limiting rods 16 on the same side penetrate the fixed block 7 in the direction away from the supporting rod 3 and are connected by a pull rod 17. A pressing groove 18 is arranged in the fixed block 7. A pressing rod 19 that is inserted into the pressing groove 18 is arranged at the lower end of the limiting rod 16. The pressing rod 19 is connected to the side wall of the pressing groove 18 through a V-shaped elastic piece 20.

[0020] For the convenience of the movement of the clamping plate 8, a threaded knob 21 is threadedly connected to the fixed block 7, and the upper end of the threaded knob 21 is rotatably connected to the clamping plate 8.

[0021] When the utility model is in use, anti-slip pads are respectively arranged on the clamping plate 8 and the fixed block 7. During installation, the two main supporting plates 1 and the supporting rods 3 on both sides can be separately installed. First, install the left clamping device on the transfer tool. First, insert the bed boards or brackets on both sides of the transfer tool into the notch of the fixed block 7, and then rotate the threaded knob 21 clockwise to make the clamping plate 8 move upward and clamp the bed board or bracket. Then install the clamping device on the other side to align the two main supporting plates 1, as shown in the distribution relationship in the attached drawing;

[0022] At this time, the required fixing appliance can be placed in the placement groove 6. At the same time, the positioning belt 12 can be used to bypass the instrument and pass through the positioning ring 13, so that the magic sub - sticker is bonded to the magic mother - sticker to squeeze and fix the instrument. When not in use, only the support rod 3 can be removed. At this time, pull the pull rod 17 outwards, so that the pull rod 17 drives the limit rod 16 to move and makes it move out of the limit groove 15, and then the support rod 3 can be pulled out upwards;

[0023] Similarly, the two support rods 3 on the other side are moved upwards out of the corresponding fixing blocks 7 on their respective sides. After releasing the pull rod 17, under the action of the V - shaped elastic piece 20, the limit rod 16 resets. If it is necessary to reinstall the support rod 3 in the fixing block 7, only need to insert the support rod 3 into the slot 14. The lower end of the support rod 3 first contacts the inclined surface of the limit rod 16 and pushes the limit rod 16 to move to one side of the limit groove 15. When the limit rod 16 moves to the stepped surface of the limit groove 15, under the action of the elastic piece 20, it is inserted into the upper side of the limit groove 15. At this time, it contacts the stepped surface of the limit groove 15 to limit the up - and - down movement of the support rod 3.

[0024] The structure of the utility model is reasonable and easy to use. By setting the main support plate, side support plate, connecting column and rotating column, it is convenient for medical staff to place some life - sustaining instruments during the patient transfer process, avoiding the situation that when the instruments are placed on the transfer stretcher or transfer bed, they occupy the flat - lying space of the patient, and also avoiding the extra burden on the patient's body caused by placing the instruments on the patient. It is beneficial to the nursing operation of medical staff during the patient transfer process. At the same time, when not in use, only the support frame needs to be removed and the clamping device is retained, so that when used next time, the support frame can be quickly disassembled and assembled, and the main support plate and side support plate can be folded and placed, avoiding the situation that the transfer tool is idle and the storage space is too large and not easy to place, and avoiding the reduction of the transfer efficiency of medical staff caused by repeated disassembly and assembly. It is beneficial for medical staff and patients to use. This structure is simple, easy to operate, novel in conception and strong in practicability.
