Description
Technical Field
[0001] This invention relates to the field of catheter fixation technology, specifically to a catheter fixation device for surgical care. Background Technology
[0002] Catheter fixation devices are tools used to secure and stabilize medical catheters. They play an important role in various surgical procedures and treatments, ensuring that the catheter does not move, thereby reducing the risk of complications and improving patient comfort.
[0003] Patent publication number CN214596771U relates to a surgical catheter fixation device, comprising two support columns for providing support and a connecting shaft rotatably mounted between the two support columns. The connecting shaft is provided with a catheter fixation mechanism to prevent catheter entanglement or bending, thereby improving the nursing and treatment effect. This surgical catheter fixation device, unlike existing technologies, prevents catheter entanglement or bending when patients have multiple indwelling catheters during turning over. The catheter fixation mechanism facilitates the fixation of catheters, enabling normal nursing work, improving the treatment effect to a certain extent, and greatly reducing catheter dislodgement, blood backflow, and other phenomena, thus ensuring the patient's life safety.
[0004] The aforementioned patents improve treatment effectiveness to a certain extent and greatly reduce phenomena such as catheter dislodgement and blood backflow, thus ensuring the safety of patients. However, when injecting patients, it is necessary to adjust the injection position and fix the syringe. Changes in the syringe during injection can cause harm to the patient and threaten their life. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a catheter fixation device for surgical care, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a surgical catheter fixation device, comprising a support plate, a support frame fixedly installed at the bottom of the support plate, a connecting block fixedly installed at the top of the support plate, a sliding groove provided at the top of the support plate, and an injection device, an adjustment device, and a fixing device provided at the top of the support plate. The injection device includes a lower clamp, an upper clamp, a fixed frame, a syringe, a sliding rod, an arc-shaped clamp, a fixed block, and a reset telescopic rod. The lower clamp is fixedly installed on the top of the connecting block, and a rotating groove is formed on the top of the lower clamp. The upper clamp is rotatably installed in the rotating groove on the top of the lower clamp, and a square groove is formed on the arc surface of the upper clamp. The fixed frame is slidably installed on the inner wall of the square groove, and a fixed hole is formed on the surface of the fixed frame. The syringe is placed on the inner wall of the fixed hole. The sliding rod is slidably installed on the side of the fixed frame near the fixed hole. The arc-shaped clamp is fixedly installed on the end of the sliding rod away from the fixed frame. The syringe is placed between the arc-shaped clamps. The fixed block is fixedly installed at the bottom of the arc-shaped clamp. The output end of the reset telescopic rod is fixedly installed between the fixed blocks. Pulling the arc-shaped clamp moves it, placing the syringe inside the fixed hole. Then, releasing the arc-shaped clamp causes it to reset via a spring, which in turn resets the reset telescopic rod. The reset telescopic rod then moves the fixed block to the opposite position, and the movement of the fixed block moves the arc-shaped clamp towards the syringe.
[0007] According to the above technical solution, a No. 1 spring is provided inside the reset telescopic rod. The syringe contacts the arc-shaped clamp and drives the reset spring to reset through the No. 1 spring.
[0008] According to the above technical solution, the adjustment device includes a fixing component, a rotating shaft, a strap, a guide rod, and a fixing frame. The fixing component is fixedly installed on the surface of the fixing frame. The rotating shaft is rotatably installed on the opposite side of the fixing component. The strap is fixedly installed between the rotating shafts. The guide rod is fixedly installed on the top of the inner arc surface of the lower clamp. A U-shaped groove is opened on the surface of the lower clamp. The fixing frame is fixedly installed on the top of the support plate. Then, the strap is passed through the U-shaped groove. After the strap passes through the U-shaped groove, pulling the strap will change the direction of force on the strap due to the obstruction of the U-shaped groove and the guide rod. The strap will then bind the patient's arm.
[0009] According to the above technical solution, the adjusting device further includes a lead screw, a first baffle, a second baffle, an elastic telescopic rod, and a collar. The lead screw is sleeved on the opposite side of the fixed frame. The circumferential surface of the lead screw is provided with Velcro. The first baffle is fixedly installed on the circumferential surface of the lead screw. The second baffle is fixedly installed on the surface of the fixed frame. The elastic telescopic rod is fixedly installed on the top of the support plate. The collar is fixedly installed on the top of the output end of the elastic telescopic rod. When the first baffle rotates, it will contact and be blocked by the second baffle, preventing the lead screw from continuing to rotate. After the lead screw cannot rotate, the strap cannot continue to be pulled to the bottom. Thus, after the patient's arm is fixed, the lead screw will prevent the strap from continuing to be pulled to the bottom.
[0010] According to the above technical solution, the strap contacts the guide rod, and a torsion spring is provided between the rotating shaft and the fixing component, which drives the rotating shaft to reset.
[0011] According to the above technical solution, the fixing device includes a sliding plate, a hollow column, a rotating plate, a wire-fixing hook, a limiting plate, a reset plate, and an adjusting rod. The sliding plate is slidably installed on the inner wall of the sliding groove. The hollow column is fixedly installed on the top of the sliding plate, and a fixing hole is opened on the surface of the hollow column. The adjusting rod is slidably installed on the inner wall of the hollow column, and an adjusting hole is opened on the surface of the adjusting rod. The rotating plate is rotatably installed on the top of the adjusting rod. The wire-fixing hook is fixedly installed on the top of the rotating plate. The limiting plate is disposed on the surface of the hollow column. The reset plate is fixedly installed on the side of the limiting plate near the adjusting hole. The reset plate is driven to reset by a second spring. The reset plate resets the adjusting rod and the hollow column, placing the guide tube inside the wire-fixing hook and sliding the sliding plate to the desired position.
[0012] According to the above technical solution, the fixing device further includes an L-shaped rod and a wire fastener. The L-shaped rod is fixedly installed on the circumferential surface of the output end of the elastic telescopic rod, and the wire fastener is fixedly installed at the bottom of the L-shaped rod. When the output end of the elastic telescopic rod moves to the bottom, it will drive the L-shaped rod to move to the bottom. When the L-shaped rod moves to the bottom, it will drive the wire fastener to move to the bottom. When the wire fastener moves to the bottom, it will fix the conduit, so that the conduit is fixed to the top of the support plate by the wire fastener.
[0013] According to the above technical solution, a second spring is provided between the reset plates. The reset plates are in contact with the adjustment hole, and the second spring drives the reset plates to reset.
[0014] This invention provides a catheter fixation device for surgical care. It has the following beneficial effects: (1) In this invention, the upper clamp will fix the patient's arm after rotation, so that the patient's arm cannot move during injection, preventing the patient's arm from moving during injection, which may cause injection failure or damage to blood vessels by the syringe, thus improving the protection of the patient. The arc-shaped clamp will clamp and fix the syringe, so that the patient or medical staff do not need to manually support the syringe, thus improving the practicality and stability of the device during use. (2) In this invention, the strap will bind the patient's arm to prevent the patient's arm from twitching or spasming when the syringe punctures the patient's subcutaneous tissue, which may cause the syringe to scratch the patient's skin tissue, thus improving the protection of the patient. After the patient's arm is fixed, the screw will prevent the strap from being pulled to the bottom, preventing the strap from being too tight when the patient's arm is bound too tightly, which may affect the patient's blood flow and prevent the fluid in the blood vessels from flowing into the patient's body, thus ensuring the patient's life safety and reducing the probability of medical accidents. (3) In this invention, the catheter is fixed to the top of the support plate by the cable fixer to prevent the catheter from being too long and causing the catheter to be pulled when the patient or medical staff moves, which could lead to injury to the patient and improve the patient's safety. The catheter is placed inside the cable fixation hook and the sliding plate is slid to the desired position, so that the height and angle of the catheter can be adjusted. This allows the medication to flow from the top to the bottom or be discharged from the top to the bottom when facing different situations, which improves the practicality of the device and increases the options when facing different situations.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-8 One embodiment of the present invention is: a surgical catheter fixation device, including a support plate 1, a support frame 2 fixedly installed at the bottom of the support plate 1, a connecting block 3 fixedly installed at the top of the support plate 1, a sliding groove opened at the top of the support plate 1, and an injection device provided at the top of the support plate 1. The injection device includes a lower clamp 41, an upper clamp 42, a fixing frame 43, a syringe 44, a sliding rod 45, an arc-shaped clamp 46, a fixing block 47, and a reset telescopic rod 48. The lower clamp 41 is fixedly installed on the top of the connecting block 3, and a rotating groove is provided on the top of the lower clamp 41. The upper clamp 42 is rotatably installed in the rotating groove on the top of the lower clamp 41. A square groove is provided on the arc surface of the upper clamp 42 to prevent injection failure or damage to blood vessels by the syringe 44 during injection if the patient's arm moves, thus improving patient protection. The fixing frame 43 is slidably installed on the square... The inner wall of the groove has a fixing hole on the surface of the fixing frame 43. The syringe 44 is set on the inner wall of the fixing hole. The sliding rod 45 is slidably installed on the side of the fixing frame 43 near the fixing hole. The arc-shaped clamp 46 is fixedly installed on the end of the sliding rod 45 away from the fixing frame 43. The syringe 44 is set between the arc-shaped clamps 46. The fixing block 47 is fixedly installed on the bottom of the arc-shaped clamp 46. The output end of the reset telescopic rod 48 is fixedly installed between the fixing blocks 47. This eliminates the need for the patient or medical staff to manually support the syringe 44, improving the practicality and stability of the device during use.
[0019] The reset telescopic rod 48 is equipped with a No. 1 spring. The syringe 44 contacts the arc-shaped clamp 46, and the No. 1 spring drives the reset spring to perform reset.
[0020] In this embodiment, during operation: the patient's arm is placed on top of the lower clamp 41, and then the upper clamp 42 is rotated. The rotation of the upper clamp 42 fixes the patient's arm, preventing movement during injection and thus preventing injection failure or damage to blood vessels by the syringe 44. This improves patient protection. The rotation of the upper clamp 42 causes the fixing frame 43 to rotate. After the upper clamp 42 completes its rotation, the fixing frame 43 is manually adjusted by pushing it. The movement of the fixing frame 43 causes the sliding rod 45 to move, moving it to the desired position. After placement, pull the arc-shaped clamp 46. After the arc-shaped clamp 46 moves, it places the syringe 44 inside the fixing hole. Then release the arc-shaped clamp 46. The arc-shaped clamp 46 resets through the first spring, which drives the reset telescopic rod 48 to reset. The reset telescopic rod 48 will drive the fixing block 47 to move to the opposite position. The movement of the fixing block 47 will drive the arc-shaped clamp 46 to move towards the syringe 44. The movement of the arc-shaped clamp 46 will clamp and fix the syringe 44, so that the patient or medical staff do not need to manually support the syringe 44, which improves the practicality and stability of the device during use.
[0021] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the top of the support plate 1 is provided with an adjustment device and a fixing device. The adjustment device includes a fixing member 51, a rotating shaft 52, a strap 53, a guide rod 54, and a fixing frame 55. The fixing member 51 is fixedly installed on the surface of the fixing frame 43. The rotating shaft 52 is rotatably installed on the opposite side of the fixing member 51. The strap 53 is fixedly installed between the rotating shafts 52. The guide rod 54 is fixedly installed on the top of the inner arc surface of the lower clamp 41. A U-shaped groove is opened on the surface of the lower clamp 41. The fixing frame 55 is fixedly installed on the top of the support plate 1 to prevent the patient's arm from twitching or spasming when the syringe 44 punctures the patient's subcutaneous tissue, thus preventing the syringe 44 from scratching the patient's skin tissue and improving the protection of the patient.
[0022] The adjustment device also includes a lead screw 56, a first baffle 57, a second baffle 58, an elastic telescopic rod 59, and a collar 510. The lead screw 56 is sleeved on the opposite side of the fixed frame 55. Velcro is provided on the circumferential surface of the lead screw 56. The first baffle 57 is fixedly installed on the circumferential surface of the lead screw 56. The second baffle 58 is fixedly installed on the surface of the fixed frame 55. The elastic telescopic rod 59 is fixedly installed on the top of the support plate 1. The collar 510 is fixedly installed on the top of the output end of the elastic telescopic rod 59. This prevents the strap 53 from being too tight when the patient's arm is excessively bound, which could affect the patient's blood flow and prevent the fluid in the blood vessels from flowing into the patient's body, thus ensuring the patient's life safety and reducing the probability of medical accidents.
[0023] The strap 53 contacts the guide rod 54, and a torsion spring is provided between the rotating shaft 52 and the fixing member 51. The torsion spring drives the rotating shaft 52 to reset.
[0024] The fixing device includes a sliding plate 63, a hollow column 64, a rotating plate 65, a wire-fixing hook 66, a limiting plate 67, a reset plate 68, and an adjusting rod 69. The sliding plate 63 is slidably installed on the inner wall of the sliding groove. The hollow column 64 is fixedly installed on the top of the sliding plate 63, and a fixing hole is opened on the surface of the hollow column 64. The adjusting rod 69 is slidably installed on the inner wall of the hollow column 64, and an adjusting hole is opened on the surface of the adjusting rod 69. The rotating plate 65 is rotatably installed on the top of the adjusting rod 69. The wire-fixing hook 66 is fixedly installed on the top of the rotating plate 65. The limiting plate 67 is set on the surface of the hollow column 64. The reset plate 68 is fixedly installed on the side of the limiting plate 67 near the adjusting hole. The height and angle of the conduit can be adjusted, so that in different situations, the liquid can be selected to flow from the top to the bottom or be discharged from the top to the bottom, which improves the practicality of the device and increases the selectivity in different situations.
[0025] The fixation device also includes an L-shaped rod 61 and a cable fastener 62. The L-shaped rod 61 is fixedly installed on the circumferential surface of the output end of the elastic telescopic rod 59, and the cable fastener 62 is fixedly installed on the bottom of the L-shaped rod 61 to prevent the catheter from being too long and causing the catheter to be pulled when the patient or medical staff moves, resulting in injury to the patient and improving the patient's safety.
[0026] A second spring is provided between the reset plates 68. The reset plates 68 are in contact with the adjustment hole, and the second spring drives the reset plates 68 to reset.
[0027] In this embodiment, during operation: the movement of the fixed frame 43 causes the fixed component 51 to move, which in turn causes the rotating shaft 52 to move. After the fixed frame 43 stops moving, the strap 53 is pulled, passing along the inner wall of the upper clamp 42 through the guide rod 54. The strap 53 is then pulled upwards and placed on the top of the patient's arm. The strap 53 is then passed through the U-shaped groove. After the strap 53 exits the U-shaped groove, pulling it causes the direction of force on the strap 53 to change due to the obstruction from the U-shaped groove and the guide rod 54. The strap 53 then binds the patient's arm, preventing twitching or spasms in the patient's arm when the syringe 44 punctures the subcutaneous tissue, thus preventing the syringe 44 from scratching the patient's skin and improving patient protection. After pulling the strap 53, moving it will contact... The movement of the lead screw 56 and the strap 53 causes the Velcro attached to the circumference of the lead screw 56 to adhere. As the strap 53 moves to the bottom, it drives the lead screw 56 to move to the bottom as well. The strap 53 continues to move to the bottom, and the Velcro causes the lead screw 56 to rotate. The rotation of the lead screw 56 causes the first baffle 57 to rotate. The first baffle 57 then comes into contact with and is blocked by the second baffle 58, preventing the lead screw 56 from rotating further. Once the lead screw 56 cannot rotate, the strap 53 cannot be pulled further to the bottom. This prevents the strap 53 from being pulled further to the bottom after the patient's arm has been secured. This prevents the strap from being too tight when the patient's arm is over-bound, as this could affect blood flow and prevent fluid from flowing into the patient's body, thus ensuring the patient's safety and reducing the probability of medical accidents.
[0028] Moving the lead screw 56 to the bottom will cause the collar 510 to move to the bottom. The collar 510 moving to the bottom will cause the output end of the elastic telescopic rod 59 to move to the bottom. The output end of the elastic telescopic rod 59 moving to the bottom will cause the L-shaped rod 61 to move to the bottom. The L-shaped rod 61 moving to the bottom will cause the catheter fixator 62 to move to the bottom. The catheter fixator 62 will secure the catheter to the top of the support plate 1, preventing the catheter from being too long and being pulled during patient or medical staff movement, thus improving patient safety. Manually pulling the adjusting rod 69 will move the adjusting hole. After adjusting to the desired position, pressing the reset plate 68 causes deformation, which in turn pushes the limiting plate 67 toward the fixing hole. The movement of the limiting plate 67 will cause the reset plate 68 to move. After the reset plate 68 has completely passed through the adjusting hole, the second spring will drive the reset plate 68 to reset. The reset plate 68 will limit the adjustment rod 69 and the hollow column 64. The conduit is placed inside the fixed wire hook 66, and the sliding plate 63 is slid to the desired position. The height and angle of the conduit can be adjusted, so that in different situations, the liquid can be selected to flow from the top to the bottom or be discharged from the top to the bottom, which improves the practicality of the device and increases the options for different situations.
[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
