Technical Field

[0001] The present invention relates to the technical field of high-pressure injectors, and particularly to a fixing device for a DSA high-pressure injector that is convenient for adjustment. Background Art

[0002] A DSA high-pressure injector is a medical device that can quickly inject contrast agent into a patient's blood vessel by precisely controlling the pressure, flow rate, and dose of the contrast agent, and can generate clear blood vessel images to help medical staff observe the blood vessel structure and lesion conditions.

[0003] However, existing DSA high-pressure injectors usually come with a large fixed base to ensure working stability, which results in excessive space occupation due to their large overall volume in the non-use state, making it difficult to efficiently store, and also increasing the difficulty of transportation and transfer; the common existing solution is to disassemble the device into multiple components for batch storage or transportation and reassemble it when in use; however, this process is cumbersome, significantly increasing the operation burden on medical staff and reducing clinical efficiency.

[0004] In summary, the present application proposes a fixing device for a DSA high-pressure injector that is convenient for adjustment to improve the above-mentioned technical problems. Summary of the Invention

[0005] In order to overcome the disadvantages that the high-pressure injector has a large overall volume, occupies too much space, is difficult to efficiently store, and also increases the difficulty of transportation and transfer, the present invention provides a fixing device for a DSA high-pressure injector that is convenient for adjustment.

[0006] The technical implementation solution of the present invention is: a fixing device for a DSA high-pressure injector that is convenient for adjustment, including a mounting base plate, a multi-stage telescopic rod, a contrast injector, a mounting bracket, and a control panel; the mounting base plate is fixedly connected with the multi-stage telescopic rod; the telescopic part of the multi-stage telescopic rod is connected with the contrast injector; the telescopic part of the multi-stage telescopic rod is fixedly connected with the mounting bracket; the mounting bracket is rotatably connected with the control panel; it further includes a roller bracket, a universal wheel, a protective cloth, a connecting ring, a mask cover, and a rubber cushion block; several roller brackets are rotatably connected to the mounting base plate; each roller bracket is equipped with a universal wheel; a storage groove is opened on the mounting base plate; a protective cloth is arranged in the storage groove; the lower end of the protective cloth is fixedly connected with the bottom of the storage groove, and the upper end of the protective cloth is fixedly connected with the connecting ring; several rubber cushion blocks are fixedly connected to the connecting ring, and the lower side of the rubber cushion block is arc-shaped; the telescopic part of the multi-stage telescopic rod is fixedly connected with the mask cover, and the mask cover is located above the contrast injector.

[0007] Furthermore, it further includes a first buffer sponge; each roller bracket is equipped with a first buffer sponge.

[0008] Furthermore, the roller bracket and the first buffer sponge are detachably connected.

[0009] Furthermore, it also includes a transverse telescopic rod; the telescopic portion of the multi-stage telescopic rod is rotatably connected to the transverse telescopic rod, and the telescopic portion of the transverse telescopic rod is fixedly connected to the contrast injector.

[0010] Furthermore, the rubber pad is arranged in an arc shape.

[0011] Furthermore, the width of the cross section of the connecting ring is greater than the width of the cross section of the receiving groove.

[0012] Furthermore, the top of the mask cover is configured to be in a cone shape.

[0013] Furthermore, it also includes a second buffer sponge; the second buffer sponge is installed at the bottom of the installation base plate.

[0014] Furthermore, the mounting base plate and the second buffer sponge are detachably connected.

[0015] Furthermore, a plurality of groove structures are arranged at the bottom of the buffer sponge 1 and the buffer sponge 2.

[0016] The present invention has the following advantages: The multi-stage telescopic rod is lowered and retracted, and the roller bracket and the universal wheel are rotated and retracted. At the same time, the protective cloth and the connecting ring are pulled up, and the contrast syringe and the control panel are wrapped and stored by installing the bottom plate and the cover, and fixed by the rotated roller bracket and the universal wheel, so as to reduce the size of the entire device and reduce the space it occupies, so as to facilitate subsequent storage and transportation.

[0017] By pulling up the protective cloth and keeping it straight and taut, the cover is then fully fitted and in contact with the connecting ring; then the roller bracket and the universal wheel are rotated to make the universal wheel firmly against the bottom of the connecting ring; through this design, the protective cloth can be kept in a taut state when the device is stored, so that even if it encounters an accidental impact during subsequent storage or transportation, the taut protective cloth can effectively buffer the external force and prevent damage to the internal contrast injector and control panel.

The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] Embodiment 1 A fixed device for DSA high-pressure syringe that is convenient for adjustment, referring to Figures 1 - 5 as shown, includes a mounting base plate 1, a multi-stage telescopic rod 2, a contrast syringe 3, a mounting bracket 4, and a control panel 5; the mounting base plate 1 is fixedly connected to the multi-stage telescopic rod 2; the telescopic part of the multi-stage telescopic rod 2 is connected to the contrast syringe 3; the telescopic part of the multi-stage telescopic rod 2 is fixedly connected to the mounting bracket 4; the mounting bracket 4 is rotatably connected to the control panel 5; It also includes a roller bracket 7, a universal wheel 8, a protective cloth 9, a connecting ring 10, a mask cover 11 and a rubber cushion block 111; the mounting base plate 1 is rotatably connected with four roller brackets 7 distributed in an annular array; each roller bracket 7 is equipped with a universal wheel 8; the mounting base plate 1 is provided with a storage groove 01; a protective cloth 9 is arranged in the storage groove 01; the lower end of the protective cloth 9 is fixedly connected to the bottom of the storage groove 01, and the upper end of the protective cloth 9 is fixedly connected with a connecting ring 10; the connecting ring 10 is fixedly connected with rubber cushion blocks 111 having the same number as the roller brackets 7, and the lower side of the rubber cushion block 111 is arc-shaped; the telescopic part of the multi-stage telescopic rod 2 is fixedly connected with a mask cover 11, and the mask cover 11 is located above the contrast injector 3.

[0023] It also includes a first buffer sponge 101; each roller bracket 7 is equipped with a first buffer sponge 101.

[0024] The roller bracket 7 and the first buffer sponge 101 are detachably connected. When the surface of the first buffer sponge 101 is dirty or damaged, the operator can disassemble and replace the first buffer sponge 101.

[0025] It also includes a horizontal telescopic rod 6; the telescopic part of the multi-stage telescopic rod 2 is rotatably connected with a horizontal telescopic rod 6, and the telescopic part of the horizontal telescopic rod 6 is fixedly connected with the contrast injector 3. By pulling out the horizontal telescopic rod 6, the horizontal position of the contrast injector 3 can be adjusted to meet the actual use requirements.

[0026] The rubber cushion block 111 is arc-shaped, which increases the contact area with the universal wheel 8 and improves the stability of the equipment during storage.

[0027] The width of the cross-section of the connecting ring 10 is greater than the width of the cross-section of the storage groove 01. When the protective cloth 9 is stored in the storage groove 01, the storage groove 01 is covered by the connecting ring 10, so as to store the protective cloth 9 in a sealed manner, prevent dust from contacting the inner side of the protective cloth 9, and avoid directly contaminating the contrast injector 3 and the control panel 5 with dust during subsequent use.

[0028] The top of the mask cover 11 is cone-shaped, which reduces the accumulation of dust on the top of the mask cover 11 during the storage process.

[0029] Initially, the contrast injector 3 is installed on the multi-stage telescopic rod 2 through the horizontal telescopic rod 6, and the control panel 5 is installed on the multi-stage telescopic rod 2 through the mounting bracket 4. Figure 1The figure shows the state of daily use of the high-pressure syringe. In this state, the device contacts the ground through the universal wheels 8. When the device needs to be used, medical staff can directly push the device to move near the examination bed where the patient is located. Subsequently, the medical staff adds the required contrast agent into the contrast syringe 3, connects the injection tube and the needle to the contrast syringe 3. Then, the medical staff inserts the needle into the patient's blood vessel and injects the contrast agent into the patient's blood vessel through controlling the contrast syringe 3 to generate clear blood vessel images to help observe the blood vessel structure and lesion conditions. During the use of the contrast syringe 3, the medical staff adjusts the height of the multi-stage telescopic rod 2 and the length of the horizontal telescopic rod 6, so as to respectively adjust the vertical and horizontal positions of the contrast syringe 3 to meet the actual use requirements. In addition, the overall support and stability are achieved through the installation base plate 1, the roller bracket 7 and the universal wheels 8 to ensure the stability during the use of the contrast syringe 3.

[0030] However, existing DSA high-pressure syringes usually come with a large fixed base to ensure working stability, which results in excessive space occupation due to their large overall volume in the non-use state, making it difficult to efficiently store, and at the same time increasing the difficulty of transportation and transfer. To solve the above problems, when the device is in the non-use state, first, the medical staff manually retracts the horizontal telescopic rod 6 to make the contrast syringe 3 close to the multi-stage telescopic rod 2, and then rotates and retracts the control panel 5. Next, the medical staff manually retracts the multi-stage telescopic rod 2 to lower the contrast syringe 3, the control panel 5 and the mask cover 11. While retracting the multi-stage telescopic rod 2, the medical staff lifts the connecting ring 10 and pulls up and unfolds the protective cloth 9 stored in the storage groove 01 until the protective cloth 9 is straightened and tightened. As the multi-stage telescopic rod 2 continues to retract, when the mask cover 11 descends to fit with the connecting ring 10, it stops descending. At this time, the installation base plate 1, the protective cloth 9, the connecting ring 10 and the mask cover 11 jointly enclose a closed space, and the contrast syringe 3 and the control panel 5 are located inside this closed space. Then, the medical staff manually rotates the roller bracket 7, rotates and retracts the roller bracket 7, and makes the universal wheels 8 abut against the bottom of the connecting ring 10, as Figure 4As shown, the raised protective cloth 9 and the connecting ring 10 are restricted and fixed by the roller bracket 7 and the universal wheel 8, so that the storage of the whole device is completed; by lowering and contracting the multi-stage telescopic rod 2, rotating and retracting the roller bracket 7 and the universal wheel 8, and pulling up the protective cloth 9 and the connecting ring 10 at the same time, the contrast syringe 3 and the control panel 5 are wrapped and stored in cooperation with the installation base plate 1 and the shield cover 11, and fixed by the rotated roller bracket 7 and the universal wheel 8, so as to reduce the volume of the whole device and reduce the space occupied by it, so as to facilitate the subsequent storage and transportation transfer; at the same time, the contrast syringe 3 and the control panel 5 are stored and isolated by installing the base plate 1, the protective cloth 9, the connecting ring 10 and the shield cover 11, so that the device is prevented from contacting with the contrast syringe 3 and the control panel 5 by external dust when not in use, so as to prevent external dust from contaminating the device and affecting the subsequent use. Compared with the prior art in which the device is disassembled into multiple parts for storage or transportation in batches, and then reassembled when used, the present invention can simplify the storage operation of the device when not in use and reduce the operating burden of medical staff.

[0031] During manual operation, the protective cloth 9 is first pulled up and kept in a straight and taut state, and then the mask cover 11 is fully fitted and contacted with the connecting ring 10; then the roller bracket 7 and the universal wheel 8 are rotated to make the universal wheel 8 firmly against the bottom of the connecting ring 10; through this design, the device can ensure that the protective cloth 9 is continuously in a taut state when it is stored, so that even if it encounters an accidental impact during subsequent storage or transportation, the taut protective cloth 9 can effectively buffer the external force and avoid damage to the internal contrast injector 3 and the control panel 5.

[0032] In addition, the rotated roller bracket 7 is distributed in a circular array on the outside of the protective cloth 9, and the buffer sponge 101 arranged on its surface can form double protection: when the equipment falls accidentally, the buffer sponge 101 can absorb the impact energy, and further prevent the internal precision components from being damaged due to collision; this structural design takes into account both storage stability and transportation safety, and significantly improves the protection performance of the equipment through the synergistic effect of mechanical locking and flexible buffering.

[0033] It should be noted that a rubber pad 111 is provided at the bottom of the connecting ring 10. Figure 5 As shown, when the rotating roller bracket 7 makes the universal wheel 8 tightly abut against the rubber pad 111, the arc surface structure on the lower side of the rubber pad 111 can increase the contact area with the universal wheel 8, and its surface material properties can also significantly enhance the friction of the contact surface, thereby improving the stability of the equipment when it is stored.

[0034] When the device is converted from the storage state to the use state, first, manually rotate and open the roller bracket 7 and the universal wheels 8. Then, lower and reset the protective cloth 9 and the connecting ring 10, and re-store the protective cloth 9 in the storage groove 01. Subsequently, pull up the multi-stage telescopic rod 2 and the parts connected thereto for use. It should be noted that the width of the cross-section of the connecting ring 10 is greater than the width of the cross-section of the storage groove 01. After the protective cloth 9 is stored in the storage groove 01, the storage groove 01 is covered by the connecting ring 10 to prevent dust from contacting the inner side of the protective cloth 9, so that in the subsequent use process, the dust directly contacts the contrast injector 3 and the control panel 5.

[0035] Embodiment 2 On the basis of Embodiment 1, with reference to Figure 1 、 Figure 6 and Figure 7 as shown, it further includes a second buffer sponge 102; a second buffer sponge 102 is installed at the bottom of the mounting base plate 1.

[0036] The mounting base plate 1 and the second buffer sponge 102 are detachably connected. When the second buffer sponge 102 is dirty or damaged, it can be conveniently disassembled and replaced manually.

[0037] A number of groove structures are provided at the bottoms of the first buffer sponge 101 and the second buffer sponge 102, which can increase the friction with the ground and improve the stability of the device during operation.

[0038] On the basis of the above-mentioned Embodiment 1, during use, the device relies on the universal wheels 8 to contact the ground to facilitate moving it to the examination bed near the patient. When the device reaches the designated position, start the contrast injector 3 to inject the intravascular contrast agent into the patient. However, during operation, the device is prone to slide due to the collision of passing medical staff, affecting the injection accuracy of the contrast agent. Even if the universal wheels 8 are locked before operation, due to the form of contact between it and the ground being line-to-surface contact, the device may still slide when being collided. Based on the above problems, when the medical staff move this device to the designated position, then manually directly press down the mounting base plate 1, and the roller bracket 7 rotates passively until the mounting base plate 1 contacts the ground, as Figure 6 shown. At this time, both the mounting base plate 1 and the roller bracket 7 contact the ground simultaneously, thereby increasing the contact area of the device with the ground during operation and improving the stability of the device during operation, avoiding the situation that the device is prone to slide when being collided during operation; and, a second buffer sponge 102 is provided at the bottom of the mounting base plate 1. When the mounting base plate 1 and the roller bracket 7 contact the ground, they contact the ground through the first buffer sponge 101 and the second buffer sponge 102, increasing the friction when the device contacts the ground and further improving the stability of the device during operation to ensure the normal injection of the contrast agent.

[0039] When the device is in the storage state, it is stably placed by contacting the ground or the desktop through the mounting base plate 1. The stability of the device during static placement is increased by the second buffer sponge 102 provided at the bottom of the mounting base plate 1. In the event of an accidental drop during the transportation or transfer of the device, the second buffer sponge 102 provided at the bottom of the mounting base plate 1 can also buffer the impact received during the drop, thereby protecting the contrast injector 3 and the control panel 5 inside the device. This not only ensures the stability of the device during daily use but also provides additional protection for the safety of the device in unforeseen situations.

Therefore, the scope of the present disclosure should not be limited to the above embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
