Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a fixation device for preventing intravenous treatment loss. Background Technology

[0002] Intravenous therapy is a treatment method that involves injecting various drugs into the bloodstream through a vein. It has the advantages of rapid drug administration and quick onset of action, and is a commonly used treatment method in clinical practice.

[0003] In most cases, intravenous infusions are administered for extended periods. To prevent the IV needle from dislodging and ensure the infusion continues smoothly, children generally need to remain relatively still, requiring controlled limb movement. Since children are typically active and energetic, their movements can easily dislodge the IV needle. To prevent this, children are usually secured to a chair to minimize movement during the infusion. However, this method is not suitable for all children, and some children, out of curiosity or discomfort, may attempt to remove the tape securing the IV needle. This method does not effectively protect the IV needle attachment site.

[0004] To address the above problems, this invention proposes a fixation device for preventing intravenous treatment loss. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a fixation device for preventing intravenous treatment loss.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an intravenous therapy anti-dislodgement fixation device, including a seat, with an infusion stand provided on one side of the seat; A support plate is provided on one side of the seat, and a support assembly is provided on the support plate. The support assembly includes a first plate, a second plate, and a third plate connected in sequence. The first plate is vertically rotatably connected to the support plate. The first plate is rotatably connected to the second plate via a first pivot, and the second plate is rotatably connected to the third plate via a second pivot. The front and rear ends of the first, second, and third plates are all provided with inclined surfaces. A sliding plate is slidably provided on the upper end surface of the support assembly, and a placement plate is rotatably provided on the sliding plate. A restraint assembly is provided on the placement plate. By rotating the support assembly so that it is perpendicular to the support plate, the sliding plate is positioned on the first plate. Then, the second plate rotates around the first pivot, and the third plate rotates around the second pivot, thereby forming a placement cavity with a triangular cross-section, and the placement plate is located inside the placement cavity.

[0007] Furthermore, the support plate is provided with a first arc-shaped relief groove that mates with the first rotating shaft, and the support plate is provided with a second arc-shaped relief groove that mates with the second rotating shaft; both the first arc-shaped relief groove and the second arc-shaped relief groove penetrate the outer side of the support plate.

[0008] Furthermore, both the first arc-shaped relief groove and the second arc-shaped relief groove are concentrically arranged with the rotation axis between the first plate and the support plate.

[0009] Furthermore, a first electric telescopic rod is connected between the first plate and the second plate, and a second electric telescopic rod is connected between the second plate and the third plate.

[0010] Furthermore, the first plate, the second plate, and the third plate are all provided with limiting grooves, and sliding grooves are provided on both sides of the limiting grooves. Sliding blocks that slide in cooperation with the sliding grooves are provided on both sides of the sliding plate.

[0011] Furthermore, a motor is fixedly installed inside the support plate, with the motor shaft pointing vertically upward and fixedly connected to the first plate.

[0012] Furthermore, the restraint assembly includes straps that are connected to the placement plate.

[0013] Furthermore, the infusion stand includes a fixing rod and a hook, the fixing rod being mounted on one side of the seat, and the hook being disposed at the top of the fixing rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the support assembly is in the deployed state, the slide can slide on the support assembly, and the placement board can rotate on the slide, allowing the patient to move their arm appropriately to relieve the discomfort caused by prolonged arm immobility.

[0015] When the support assembly is in the folded state, the first plate, the second plate, and the third plate form a placement cavity. The strap and the fixing part of the infusion needle are all inside the placement cavity, thus preventing children from opening the strap or tearing the tape fixing the infusion needle. It also prevents children or others from accidentally touching the tape and strap, causing the tape and strap to loosen and the infusion needle to fall off. It is suitable for children with poor limb control.

[0016] This invention allows for the selection of different usage states based on the patient's specific condition, thereby improving the applicability of the device. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A fixation device for preventing intravenous treatment loss includes a seat 1, an infusion stand and a support assembly.

[0021] An IV stand is installed on one side of the seat 1 to support the IV bottle. The IV stand includes a fixing rod 17 and a hook 18. The fixing rod 17 is installed on one side of the seat 1, and the hook 18 is installed on the upper end of the fixing rod 17.

[0022] A support plate 2 is provided on one side of the seat 1. The support assembly is located on the upper surface of the support plate 2. During intravenous infusion, the patient's arm is placed on the support assembly.

[0023] The support assembly includes a first plate 4, a second plate 5, and a third plate 6 connected in sequence. The first plate 4 is rotatably mounted on the front end of the support plate 2. Specifically, a motor 3 is embedded and fixedly mounted within the support plate 2, with the motor shaft of the motor 3 pointing vertically upwards. The first plate 4 is fixedly connected to the motor shaft of the motor 3. The motor 3 has a self-locking function. The second plate 5 is rotatably connected to the first plate 4 via a first rotating shaft 7, and the end of the second plate 5 facing away from the first plate 4 is rotatably connected to the third plate 6 via a second rotating shaft 701. The first plate 4, the second plate 5, and the third plate 6 all have inclined surfaces at both their front and rear ends.

[0024] First electric telescopic rods 10 are installed on both sides of the first plate 4, and the output end of the first electric telescopic rods 10 is connected to the second plate 5. Second electric telescopic rods 101 are installed on both sides of the second plate 5, and the output end of the second electric telescopic rods 101 is connected to the third plate 6. The first electric telescopic rods 10 cause the second plate 5 to rotate around the first rotating shaft 7. The second electric telescopic rods 101 cause the third plate 6 to rotate around the second rotating shaft 701, thereby causing the first plate 4, the second plate 5, and the third plate 6 to form a placement cavity with a triangular cross-section, and the support assembly is in a folded state. At this time, the adjacent inclined surfaces of the first plate 4 and the second plate 5 are fitted together, the adjacent inclined surfaces of the second plate 5 and the third plate 6 are fitted together, and the inclined surfaces of the front end of the first plate 4 and the rear end of the third plate 6 are fitted together. During infusion, the placement plate 13 is located in the placement cavity, thereby protecting the fixing part of the infusion needle and preventing children from tearing off the tape fixing the infusion needle.

[0025] The support assembly is equipped with a sliding plate 11 for upper limit sliding. Specifically, the upper surfaces of the first plate 4, the second plate 5, and the third plate 6 are all provided with limiting grooves extending through their front and rear ends. Sliding grooves 8 are provided on both sides of the limiting grooves, and sliders 12 that slide in cooperation with the sliding grooves 8 are fixedly connected to both sides of the sliding plate 11. The sliding plate 11 is limited and slidably positioned within the limiting grooves by the sliders 12. Stops 9 are fixedly installed at both ends of the support assembly, namely the front end of the first plate 4 and the rear end of the third plate 6. The stops 9 are used to prevent the sliding plate 11 from falling out of the limiting grooves.

[0026] A placement plate 13 is rotatably mounted on the upper surface of the slide plate 11, and there is a certain rotational damping between the placement plate 13 and the slide plate 11.

[0027] A restraint assembly is provided on the upper surface of the placement plate 13. The restraint assembly includes straps 14, one end of which is fixedly connected to the placement plate 13. In this embodiment, there are two sets of straps 14, each set including two straps 14. The two straps 14 in the same set are fixedly connected to each other, thereby restraining the patient's arm on the placement plate 13.

[0028] The upper surface of the support plate 2 is provided with a first arc-shaped relief groove 15 and a second arc-shaped relief groove 16, both of which are concentrically arranged with the motor 3. Both the first arc-shaped relief groove 15 and the second arc-shaped relief groove 16 penetrate the outer surface of the support plate 2. The first rotating shaft 7 is slidably engaged with the first arc-shaped relief groove 15, and the second rotating shaft 701 is slidably engaged with the second arc-shaped relief groove 16. When the second plate 5 and the third plate 6 are both on the support plate 2, the first rotating shaft 7 is located within the first arc-shaped relief groove 15, and the second rotating shaft 701 is located within the second arc-shaped relief groove 16, thereby limiting the movement of the second plate 5 and the third plate 6, ensuring that the lower surfaces of the first plate 4, the second plate 5, and the third plate 6 remain in contact with the upper surface of the support plate 2. The dimensions of the first arc-shaped relief groove 15 and the second arc-shaped relief groove 16 should be reasonably set so that the first rotating shaft 7 can slide smoothly in the first arc-shaped relief groove 15 and the second rotating shaft 701 can slide smoothly in the second arc-shaped relief groove 16.

[0029] Working principle: Initially, the support assembly is in the unfolded state, that is, the first plate 4, the second plate 5 and the third plate 6 are in a straight line, and the first plate 4, the second plate 5 and the third plate 6 are all in contact with the upper end surface of the support plate 2. The first rotating shaft 7 is in the first arc-shaped relief groove 15 and the second rotating shaft 701 is in the second arc-shaped relief groove 16.

[0030] For older children with some limb control, this device can be used with the support assembly deployed. In use, the patient sits on seat 1, and slides slider 12 on the support assembly to adjust the position of placement plate 13. The arm is then placed on the support assembly, with the puncture site positioned on placement plate 13. The restraint assembly then secures the patient's arm to placement plate 13. Medical personnel can then perform the puncture and infusion. During the infusion, the patient can rotate their arm, causing placement plate 13 to rotate relative to slide plate 11. The patient can also move their arm back and forth, causing slide plate 11 to slide along the support assembly. In other words, the patient's arm can be moved moderately to alleviate discomfort caused by prolonged immobility.

[0031] For younger children with poor limb control, in order to ensure the smooth progress of the infusion process, the support assembly can be folded so that the first plate 4, the second plate 5, and the third plate 6 form a placement cavity to protect the fixation point of the infusion needle.

[0032] Specifically, start motor 3 to rotate the support assembly outward by 90 degrees. Then move slide plate 11 so that it is positioned on the first plate 4. At this time, the support assembly is perpendicular to the support plate 2. After that, rotate the placement plate 13, which rotates 90 degrees relative to the slider 12, so that the arm can be easily fixed to the placement plate 13 by the straps.

[0033] Subsequently, the patient's arm to be punctured is placed on the placement plate 13 and secured with the strap 14. Puncture is then performed, and the infusion needle is fixed. The first and second electric telescopic rods 10 and 101 are activated, causing them to shorten. The first electric telescopic rod 10 drives the second plate 5 to rotate around the first rotating shaft 7, and the second electric telescopic rod 101 drives the third plate 6 to rotate around the second rotating shaft 701. This causes the first plate 4, second plate 5, and third plate 6 to form a triangular placement cavity. At this point, the strap 14 and the fixation point of the infusion needle are located within the placement cavity, preventing children from untying the strap 14 or tearing off the tape securing the infusion needle. It also prevents accidental contact by children or others that could loosen the tape and strap 14, causing the infusion needle to fall out.

[0034] At this time, the slide plate 11 is limited by the second plate 5 and the third plate 6 and cannot slide freely, and the placement plate 13 is limited by the second plate 5 and the third plate 6 and cannot rotate freely, thereby preventing the child's arm from swinging freely and helping the infusion process to proceed smoothly.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
