[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-Figure 6 As shown, a multifunctional PICC auxiliary bracket includes a base component 1, a splint component 2 and a clamping component 3; the base component 1 is placed on a hospital bed, the splint component 2 is connected to the base component 1, the clamping component 3 is arranged on the splint component 2, and is used to clamp the patient's surgical limb, and the splint component 2 is in an incomplete ring shape; the clamping component includes an airbag component 31, a clamping mechanism 32, and a slide rail 33; the number of airbag components 31 is two, which are symmetrically arranged at both ends of the splint component 2, one side of the airbag component 31 is fixedly arranged on the clamping component 3, and the other side is slidably connected to the slide rail 33; the sliding side of any airbag component 31 is connected to the clamping mechanism 32, which is used to abut the clamping mechanism 32 to tighten the loose skin when the airbag component 31 is inflated;

[0028] The base assembly 1 is placed on the bed to provide a stable support base for the entire support, ensuring that the support will not be displaced due to external force or patient movement during operation; the splint assembly 2 is designed in an incomplete ring shape, which can not only clamp the operated limb, but also reserve a certain space for convenient tube placement. Through the connection with the base assembly 1, the splint assembly 2 can be firmly positioned around the patient's operated limb. The clamping assembly 3 is arranged on the splint assembly 2, and is equipped with an airbag component 31, a clamping mechanism 32 and a slide rail 33. When the patient's operated limb needs to be fixed, the airbag component 31 is inflated by an inflating device. As the airbag component 31 expands, its sliding edge moves along the slide rail 33 and pushes the clamping mechanism 32 to apply pressure in the direction of the operated limb. This pressure tightens the skin around the operated limb to the back of the tube placement, thereby tightening the loose skin of the elderly, reducing the increased difficulty of puncture caused by loose skin and the pain caused to the patient. At the same time, a sensor is provided on the airbag component 31 to sense the clamping force of the airbag component 31 on the surgical limb, accurately control the inflation amount of the airbag component 31, and adjust the clamping force to ensure that the surgical limb can be stably fixed and adapted to surgical limbs of different sizes without causing discomfort to the patient. In short, the airbag component 31 can adapt to surgical limbs of different sizes, and a slide rail 33 is provided at the same time, so that the airbag pushes the clamping mechanism 32 to move toward the outside of the puncture point during the inflation process. The movement process clamps the patient's loose skin to both sides, so that the skin at the catheter placement point is tightened, which can make the clamping component 3 adapt to surgical limbs of different sizes and improve the applicability of the stent, and can also tighten the skin of patients with loose skin, thereby ensuring the smooth progress of the puncture and reducing the pain of the patient.

[0029] In one embodiment, the clamping mechanism 32 includes a rubber pad 321 and a plurality of elastic members 322. The elastic members 322 connect the rubber pad 321 to the splint assembly 2. The plurality of elastic members 322 are equidistantly distributed. The rubber pad 321 is L-shaped, with a short side fixedly connected to the airbag member 31 and a long side in contact with human skin. When the airbag member 31 begins to be inflated by the inflation device, its volume gradually increases. Since one side of the airbag member 31 is fixed to the clamping assembly 3 and the other side is connected to the splint assembly 2 through the slide rail 33, as the airbag expands, the unfixed side thereof will move along the slide rail 33 toward the inner side of the splint assembly 2. The clamping mechanism 32 consists of a rubber pad 321 and a plurality of elastic members 322. The elastic members 322 are equidistantly distributed between the rubber pad 321 and the splint assembly 2, so that the rubber pad 321 can undergo elastic deformation when subjected to external force, and can also adapt to patients of different body shapes. When the airbag component 31 is inflated and moves inward, it pushes the short side of the rubber pad 321, causing the rubber pad 321 to bend inward as a whole. The long side of the rubber pad 321 contacts the human skin. As the elastic component 322 bends, the long side will exert pressure on the skin around the surgical limb and drive the skin to move, thereby achieving a clamping effect. By adjusting the inflation amount of the airbag component 31, the clamping force on the surgical limb can be controlled. The appropriate amount of clamping force can ensure the stable fixation of the surgical limb. At the same time, through the elastic effect of the rubber pad 321, the loose skin around the surgical limb is tightened to facilitate medical operations.

[0030] In one embodiment, the clamping plate assembly 2 is composed of two fixed plates 21 and a tube placement plate 22. The tube placement plate 22 is located between the two fixed plates 21 and is connected to the fixed plates 21 by a chimeric rotation connection. The two fixed plates 21 and the tube placement plate 22 are coaxially arranged and connected end to end. This connection method allows the tube placement plate 22 to rotate coaxially with the two fixed plates 21, so that the tube placement plate 22 can be rotated when the tube is placed, thereby achieving a large-scale disinfection of the tube placement area; a rotating assembly 4 is provided at one end of any fixed plate 21 close to the tube placement plate 22. The rotating assembly 4 is a key part for realizing the rotation of the tube plate 22, and it is composed of a rotating seat 41, a pulling groove 42, straight teeth 43 and round teeth 44. The rotating seat 41 is fixedly installed at the bottom of the fixed plate 21 to provide stable support. The pulling groove 42 is arranged on the rotating seat 41 for installing and sliding the straight teeth 43. The straight teeth 43 can slide freely in the pulling groove 42 and realize the rotation function of the tube plate 22 by engaging with the round teeth 44. The round teeth 44 are arranged at the bottom where the tube plate 22 and the fixed plate 21 are embedded, and match the straight teeth 43. During use, when it is necessary to adjust the angle of the tube plate 22, it is only necessary to pull the spur teeth 43 to slide in the pulling groove 42. As the spur teeth 43 slide, they will engage with the round teeth 44 at the opening of the pulling groove 42, and change the rotational movement of the spur teeth 43 into the rotational movement of the round teeth 44. When the spur teeth 43 are pulled, the tube plate 22 will rotate to expose the area that needs to be disinfected. A fixing belt 9 is also provided on one side of the opening of the two fixing plates 21, and the fixing belt 9 is used to connect the open fixing plates 21 to further clamp the arm, so that the two fixing plates 21 have better wrapping properties for the arm.

[0031] In one embodiment, a pull rod 5 is provided between the straight teeth 43 on both sides. The pull rod 5 is used to pull the straight teeth 43 at both ends to move linearly at the same time. By pulling the pull rod 5, the two straight teeth 43 can be moved together in their respective pulling grooves 42 at the same time, and then synchronously rotated from both ends of the tube placement plate 22, which can ensure that the tube placement plate 22 is subjected to uniform force, and the rotation process is smoother, so that patients have a good experience. For the operator, the operation steps of adjusting the tube placement end are reduced, and the operation is simple and convenient. In addition, the pull rod 5 and the straight teeth 43 are hinged. After the rotation is completed, the pull rod 5 is rotated and clamped on the rotating seat 41, so that during the tube placement process, the tube placement plate 22 and the fixed plate 21 can remain in a relatively static state and are not affected by external forces, thereby ensuring the smooth progress of the tube placement.

[0032] In one embodiment, the base assembly 1 is mainly composed of a base 11, a movable rail 12 and a slider 13. The base 11 serves as the supporting base of the entire assembly and has sufficient stability and load-bearing capacity. The movable rail 12 is arranged on the base 11, including a transverse movable rail 12 and a vertical movable rail 12, which are in the same plane and perpendicular to each other. This design allows the slider 13 to move freely on a two-dimensional plane, thereby driving the clamping assembly 3 to achieve precise positioning and adjustment to adapt to the adjustment of the patient's surgical limb during the catheterization process. First, through the combined use of the transverse and vertical movable rails 12, medical staff can easily adjust the position and angle of the clamping assembly 3, which not only improves the flexibility of catheterization, but also greatly reduces the workload of medical staff. Secondly, the cooperation of the movable rail 12 and the slider 13 makes the movement of the clamping assembly 3 more stable and smooth, reducing the surgical risks caused by improper operation or equipment problems. In addition, the stability and load-bearing capacity of the base 11 also ensure the stability and safety of the entire clamping assembly 3 during the operation.

[0033] In one embodiment, the base assembly 1 also includes a lifting assembly 14; the lifting assembly 14 is rotatably connected to the slider 13; the lifting assembly 14 is mainly composed of an electric lifting component 141, a Y-shaped connecting rod 142 and a fixing component 143. The electric lifting component 141 is installed on the slider 13 and can be lifted up and down according to actual needs. One end of the Y-shaped connecting rod 142 is rotatably connected to the movable end of the electric lifting component 141, and the other end is fixedly connected to the two fixed plates 21. This design enables the power of the lifting component to be evenly transmitted to the clamping assembly 3, thereby achieving a stable and smooth lifting action. In terms of working principle, when the electric lifting member 141 receives a lifting command, its movable end begins to extend and retract, thereby driving the Y-shaped connecting rod 142 to extend and retract. Since the two ends of the Y-shaped connecting rod 142 are respectively connected to the fixing plate 21 and the electric lifting member 141, it will perform corresponding lifting movements according to the extension and retraction degree of the movable end, driving the clamping assembly 3 to perform lifting movements together to meet the lifting requirements during the catheter placement process. The fixing member 143 plays a key regulating role. It is located at the connection between the electric lifting member 141 and the Y-shaped connecting rod 142. By adjusting the tightness of the two, the normal state In this state, the Y-shaped connecting rod 142 is tightly pressed against the electric lifting component 141, and the Y-shaped connecting rod 142 cannot rotate with the electric lifting component 141. If the fixed plate 21 needs to be rotated, the fixing component 143 can be rotated to adjust the tightness of the Y-shaped connecting rod 142 and the electric lifting component 141, thereby realizing the rotation function of the fixed plate 21. The addition of the lifting component 14 enables the clamping component 3 to freely adjust the height in the vertical direction, which not only improves the flexibility of the operation, but also enables medical staff to operate the clamping component 3 more conveniently, reducing the difficulty of operation caused by inappropriate height.

[0034] In one embodiment, the base 11 is provided with a suction assembly 6 for fixing to the bed, and the suction assembly 6 is used to keep the splint clamping the patient's operated limb when lifting the bed; the suction assembly 6 mainly includes an air cavity 61, a plurality of suction cups 62 and a hook rod 63. The air cavity 61 is arranged inside the base 11. As the power core of the suction assembly 6, it can control the adsorption and release of the suction cup 62 through the change of air pressure. The suction cup 62 is distributed at the bottom of the base 11 and is directly connected to the air cavity 61. When the air pressure in the air cavity 61 decreases, the suction cup 62 can be firmly adsorbed on the surface of the bed to fix the base 11. The hook rod 63 is another key component of the suction assembly 6. It is partially arranged in the air cavity 61 and partially extends to the outside of the base 11. At one end outside the base 11, the hook rod 63 is equipped with a clamping part 631 that is clamped with the edge of the bed. This design allows the base 11 to be fixed on the bed not only by the adsorption force of the suction cup 62, but also by the clamping of the hook rod 63 with the edge of the bed to achieve double fixation, further enhancing stability. In actual application, medical staff place the base 11 at the position of the corresponding arm of the bed to ensure that the suction cup 62 is in full contact with the surface of the bed. Then, the clamping portion 631 of the hook rod 63 is tightly clamped on the edge of the bed, so that the hook rod 63 moves in the air cavity 61, and the Keen people reduce the air pressure in the air cavity 61. As the air pressure decreases, the suction cup 62 begins to be adsorbed on the surface of the bed, and the base 11 is firmly fixed on the bed. Even in the process of lifting the bed, under the dual effects of the suction cup 62 and the hook rod 63, a stable position and posture can be maintained, so that the bracket can be stably placed on the bed during the process of lifting the bed; wherein the edge of the bed edge is the side of the bed lifting area away from the bed fixing area, so that even if the bracket is in an unstable state during lifting, the bracket can be fixed on the bed through the hook rod 63, and under the action of gravity, when the base 11 slides downward, it will slide with the hook rod 63, thereby further reducing the pressure in the air cavity 61, and the suction of the suction cup 62 to the bed is strengthened, which can ensure that the bed is in a non-lifted state and a lifted state and the stability of the bracket.

[0035] During alcohol disinfection, blood vessels will contract, which is not conducive to the smooth progress of puncture. It is necessary to keep the catheter arm warm. In one embodiment, a heating pad 7 is also included. The heating pad 7 is mainly composed of an electric heating element 71, an insulating layer 72 and an outer covering layer 73. The electric heating element 71 is embedded in the insulating layer 72. This design not only ensures the uniform distribution of heat, but also effectively prevents the electric heating element 71 from directly contacting the user's skin, greatly improving the safety of use. The outer covering layer 73 is made of soft and comfortable medical-grade skin-friendly fabric, which not only ensures the fit with the surgical limb, but also provides sufficient comfort. At the same time, the outer covering layer 73 also has certain wear resistance and easy cleaning properties, which is convenient for medical staff to clean and maintain during surgery. In practical applications, due to the uniform distribution of the electric heating element 71 and the good thermal insulation performance of the insulating layer 72, the surgical limb can obtain a continuous and stable insulation effect, effectively preventing problems such as poor blood circulation and vascular contraction caused by low temperature during surgery. Secondly, the skin-friendly design of the outer covering layer 73 greatly improves the patient's comfort and reduces the skin discomfort that may occur due to long-term surgery. In addition, the easy cleanability of the heating pad 7 also reduces the workload of medical staff and improves surgical efficiency.

[0036] In one embodiment, a control unit is also included, and the control unit is provided with a voice control module, an electric lifting unit, an airbag unit and a temperature control unit; the input end of the voice control module is used to collect the voice data of the electric lifting unit 141, the airbag unit 31 and the heating pad 7, and the corresponding control instructions are sent through the control unit electric lifting unit, the airbag unit and the temperature control unit; the voice control module is a key component of the control unit, and its input end is used to collect the voice data in the surrounding environment. In particular, the voice control module can identify specific voice instructions related to the electric lifting unit 141, the airbag unit 31 and the heating pad 7. These voice instructions can be simple voice commands issued by medical staff, such as "raise", "lower", "inflate", "deflate", "heat up" and "cool down". Once the voice control module captures these sound data, it will process and identify the sound signal and convert it into a command signal that the control unit can understand. Then, the control unit sends corresponding control instructions to the electric lifting unit, the airbag unit and the temperature control unit according to the identified command signal. After receiving the control instruction, the electric lifting unit will drive the lifting mechanism to perform lifting operation, thereby adjusting the height of the clamping assembly 3, which enables medical staff to easily adjust the height of the equipment as needed to adapt to different scenes and patient positions. After receiving the control instruction, the airbag unit will control the inflation and deflation process of the airbag. By adjusting the inflation amount of the airbag, the clamping force and stability of the clamping assembly 3 can be accurately controlled, which helps to ensure that the patient's surgical limb can be stably and comfortably clamped during the operation; the temperature control unit is responsible for controlling the temperature of the heating pad 7. It can heat or cool the heating pad 7 according to the instructions of the medical staff or the preset temperature parameters. By accurately controlling the temperature of the heating pad 7, in addition, the control unit can also coordinate the above units according to actual needs. For example, when adjusting the height of the clamping assembly 3, the control unit can simultaneously adjust the inflation amount of the airbag to ensure the stability and clamping force of the clamping assembly 3 during the lifting process. The intelligent control of the electric lifting unit, airbag unit and temperature control unit is realized, which not only improves the convenience of equipment operation, but also improves the comfort of patients. In addition, through voice control, medical staff can easily adjust various parameters of the equipment while keeping their hands free to operate.

[0037] In one embodiment, it also includes a battery module and a charging port 8. The battery module is used to power the control unit. The charging port 8 is set on the side of the base 11 for charging the battery module. The battery module is connected to the control unit through a circuit to achieve the transmission of electric energy. When the control unit receives instructions from the voice control module and drives each functional module to work, the battery module will provide sufficient power support. At the same time, the battery module also has a power management function, which can monitor its own power status in real time and remind the user when the power is low. The charging port 8 adopts a standard interface design to ensure compatibility with most chargers on the market. The user only needs to insert the charging cable into the charging port 8 and connect the other end to an external power supply to charge the battery module. During the charging process, the charging port 8 will also communicate with the battery module to ensure the safety and efficiency of the charging process.

[0038] PICC-assisted stent placement process

[0039] The patient lies flat on the bed, fixes the bracket to the lifting end of the bed, clamps the patient's arm on the splint assembly 2, rotates the Y-shaped connecting rod 142, abducts the patient's arm to expose the catheterization area, inflates the two fixing plates 21 by inflating the airbag component 31, fixes and clamps the patient's arm, and tightens the loose skin by the clamping assembly, and then rotates the catheterization plate 22 relative to the fixing plate 21. At this time, the catheterization plate 22 is not inflated, and the area around the catheter is fully disinfected. After disinfection, the catheterization plate 22 is rotated back to the initial state, and the airbag component 31 of the catheterization plate 22 is inflated again. At the same time, the heating pad 7 is turned on by voice control to ensure the warmth of the operated limb and avoid vasoconstriction. At this time, the catheterization end can be normally catheterized;

[0040] When inserting a catheter, the bed is lifted so that the catheter insertion is smoother under the action of gravity. When the bed is lifted, the bracket is fixed to the bed by the suction component 6, so that the bracket is lifted together with the bed; when the blood vessel is folded, the arm for inserting the catheter needs to be lifted. At this time, the slider 13 is used to slide on the base 11 and the electric lifting member 141 is raised by voice control, so that the arm is lifted. At the same time, the slider 13 slides on the moving rail 12 to adapt to the patient's body position and ensure the compatibility of the bracket and the arm; after reaching the puncture point, the electric lifting member 141 descends to flatten the arm and the limb;

[0041] Finally, after the bracket has been used for a period of time, the power becomes low and the bracket can be charged through the charging port 8.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
