Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional automatic PICC catheter puncture auxiliary frame. Background Technology

[0002] PICC catheterization is a medical procedure that involves inserting a catheter from a peripheral vein into a central vein. By inserting the catheter from a peripheral vein and extending it into a central vein, it provides patients with a long-term and safe intravenous access for treatment. It is widely used in clinical settings such as chemotherapy for tumors and long-term infusions, and is an important method of intravenous drug administration in clinical treatment.

[0003] During PICC catheter insertion, accurate selection of the puncture site, accurate measurement of the arm circumference at the puncture site, and maintaining a stable puncture environment are crucial. Precise puncture site location and arm circumference measurement allow for the appropriate catheter selection, reducing complications, while a stable operating environment improves the success rate of the puncture and ensures the smooth progress of treatment.

[0004] In existing technologies, there is a lack of specialized auxiliary means to clearly divide the puncture area, making it difficult to quickly locate the optimal puncture point; arm circumference measurement mostly relies on individual tools, which are cumbersome and lack precision; at the same time, it cannot effectively deal with loose skin, which can easily obscure blood vessels. In addition, during traditional treatment, the patient lies flat on the bed, and medical staff need to use a probe to perform puncture operations on the patient's optimal puncture area. After a long time, the staff will feel uncomfortable. All these problems affect the efficiency and safety of puncture. Summary of the Invention

An electromagnet is rotatably installed on the bottom wall of the cavity. A first spring is fixedly installed on the electromagnet. A magnetic block is fixedly installed on the end of the first spring away from the electromagnet. A limit block is fixedly installed on the magnetic block. A first limit groove that cooperates with the limit block is formed on the inner side wall of the cavity. A second limit groove is formed on the upper end face of the flat plate. The limit block cooperates with the first limit groove and the second limit groove. A return spring is fixedly installed on both the first boss and the second boss, and the other end of the return spring is fixedly connected to the inner wall of the slide groove.

[0012] Optionally, the partitioning component includes a set of partition lines formed on the flat plate, which divide the flat plate into a first region, a second region, and a third region.

[0013] Optionally, the second region is defined as the optimal puncture area with reference to the elbow crease.

[0014] Optionally, the clamping assembly includes two sets of mounting blocks respectively fixedly installed on both sides of the plate. A rotating shaft is rotatably installed between the set of mounting blocks on the same side. A pair of sleeves are fixedly installed on the rotating shaft.

[0039] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 8As shown, an embodiment of the present invention provides a multifunctional automatic PICC catheter puncture auxiliary frame, including a flat plate 10, a storage cavity 80 provided on one side of the flat plate 10, and a measuring component 20 connected to the flat plate 10 through a synchronization component 30. The measuring component 20 is used to measure the arm circumference of the optimal puncture area of ​​the patient's arm.

[0041] A partitioning component 40 is disposed on a flat plate 10 and is used to partition the puncture area of ​​the patient's arm.

[0042] A clamping assembly 50 is disposed on a flat plate 10 and is used to clamp and stretch loose skin of a patient.

[0043] In traditional treatment, patients lie flat on the bed, and medical staff need to use probes to perform punctures on the optimal puncture area. After a long time, the staff will feel uncomfortable. The tablet 10, as the basic load-bearing structure of the entire auxiliary frame, provides an installation and support platform for various functional components. When the patient's arm is placed on the tablet 10 for treatment, medical staff do not need to use probes, which reduces the pressure on medical staff and improves the treatment effect.

[0044] The measuring component 20, in conjunction with the synchronization component 30, can accurately locate the optimal puncture area of ​​the patient's arm and measure the arm circumference of that area, providing data for selecting the appropriate PICC catheter size and avoiding puncture failure or postoperative complications caused by mismatch between catheter size and arm circumference.

[0045] The partitioning component 40 can clearly divide the relevant areas of the patient's arm for puncture, helping medical staff to quickly identify the best puncture area, reduce puncture positioning time, and improve puncture efficiency;

[0046] The clamping component 50 can clamp and stretch the loose skin at the puncture site on the patient's arm, making the blood vessels at the puncture site more clearly exposed, reducing the risk of blood vessel damage during puncture, and reducing the interference of skin folds on the puncture operation, thereby improving the accuracy and success rate of puncture.

[0047] like Figures 1 to 4 As shown, the measuring component 20 includes a first boss 21 and a second boss 28 disposed opposite to each other. The first boss 21 has a mounting cavity 22. A winding shaft 23 is rotatably mounted in the mounting cavity 22. A torsion spring 24 is fixedly mounted on the winding shaft 23. The other end of the torsion spring 24 is fixedly connected to the inner wall of the mounting cavity 22. A measuring belt 25 is wound on the winding shaft 23. The measuring belt 25 is provided with a scale. A hook 27 is fixedly mounted on the measuring belt 25. A limiting hook 26 that cooperates with the hook 27 is fixedly mounted on the second boss 28.

[0048] When it is necessary to measure the arm circumference of the optimal puncture area of ​​a patient's arm, the positions of the first protrusion 21 and the second protrusion 28 are adjusted by the synchronization component 30. The measuring band 25 is pulled to release it from the take-up shaft 23 inside the first protrusion 21. At this time, the take-up shaft 23 rotates and causes the torsion spring 24 to elastically deform. After the measuring band 25 is wrapped around the optimal puncture area of ​​the patient's arm, the hook 27 on the measuring band 25 is hooked onto the limiting hook 26 of the second protrusion 28. The arm circumference data can then be read through the scale of the measuring band 25. After the measurement is completed, the hook 27 is released. Under the action of the elastic restoring force, the torsion spring 24 drives the take-up shaft 23 to rotate in the opposite direction, automatically retracting the measuring band 25 and winding it back onto the take-up shaft 23, thus realizing the storage and reset of the measuring band 25. The operation is simple, the measurement is accurate, and the efficiency and accuracy of arm circumference measurement are improved.

[0049] like Figures 1 to 6 As shown, the synchronization component 30 includes a groove 31 formed within the flat plate 10. A first boss 21 and a second boss 28 are slidably mounted at both ends of the groove 31. A first toothed plate 32 is fixedly mounted on the first boss 21, and a second toothed plate 33 is fixedly mounted on the second boss 28. A gear 35 is disposed between the first toothed plate 32 and the second toothed plate 33, meshing with both the first toothed plate 32 and the second toothed plate 33. The gear 35 is rotatably mounted within the groove 31. A cavity 36 is formed within the gear 35, and an electromagnet 37 is rotatably mounted on the bottom wall of the cavity 36. A first spring 38 is fixedly mounted on the electromagnet 37. A magnetic block 39 is fixedly mounted on the end of the first spring 38 away from the electromagnet 37. A limiting block 310 is fixedly mounted on the magnetic block 39. A first limiting groove 311 that cooperates with the limiting block 310 is formed in the cavity 36. A second limiting groove 312 is formed on the plate 10. The limiting block 310 cooperates with the first limiting groove 311 and the second limiting groove 312. The two ends of the sliding groove 31 protrude outside the surface of the plate 10, so that the first boss 21 and the second boss 28 can slide a certain distance on the platform 10 and then be limited. The middle part of the sliding groove 31 is located below the surface of the plate 10. The second limiting groove 312 is formed on the surface of the plate 10 so that the limiting block 310 can be limited by the second limiting groove 312. A return spring 34 is fixedly installed on both the first boss 21 and the second boss 28, and the other end of the return spring 34 is fixedly connected to the inner wall of the slide groove 31; the first boss 21 and the second boss 28 can slide relative to the surface of the plate 10 through the slide groove 31. The contour of the first limiting groove 311 and the second limiting groove 312 after they are connected is adapted to the outer contour of the limiting block 310.

[0050] When adjusting the positions of the first protrusion 21 and the second protrusion 28 within the groove 31 on the flat plate 10, the first toothed plate 32 on the first protrusion 21 and the second toothed plate 33 on the second protrusion 28 will synchronously drive the intermediate gear 35 to rotate, ensuring that the first protrusion 21 and the second protrusion 28 always move symmetrically around the gear 35, and stretch the return spring 34, ensuring that the measuring band 25 can always be directly facing the measurement area of ​​the patient's arm, and can adapt to arms of different thicknesses, improving the accuracy of measurement. When it is necessary to fix the positions of the first protrusion 21 and the second protrusion 28, the electromagnet 37 is energized, and the electromagnet 37 generates magnetic force to attract the magnetic block 39, causing the magnetic block 39 to compress the first spring 38 and drive the limiting block 310 to move. The limiting block 310 simultaneously engages with the first limiting block in the cavity 36 of the gear 35. The gear 35 is fixed in the groove 311 and the second limiting groove 312 on the plate 10. The first boss 21 and the second boss 28 are fixed in position by the meshing relationship between the gear 35 and the first tooth plate 32 and the second tooth plate 33. When the position needs to be adjusted again, the power supply of the electromagnet 37 is cut off, the magnetic force of the electromagnet 37 disappears, and the first spring 38 pushes the magnetic block 39 to reset under the action of elastic restoring force, which drives the limiting block 310 to disengage from the first limiting groove 311. The gear 35 resumes rotation. At this time, the elastic force of the reset spring 34 can slide to adjust the position of the first boss 21 and the second boss 28 again, realizing the synchronous movement and precise positioning of the first boss 21 and the second boss 28, ensuring the measurement accuracy of the measuring component 20, and at the same time, the operation is flexible and convenient, improving the ease of use of the auxiliary frame. Specifically, after the limit block 310 disengages from the first limit slot 311, it will enter the second limit slot 312. At this time, the limit block 310 will not restrict the rotation of the gear 35. The limit block 310 can be regarded as always being in the second limit slot 312, only with different depths. The purpose of the limit block 310 is to be inserted into the gear 35 to limit it when necessary.

[0051] like Figure 2 As shown, the partitioning component 40 includes a set of partition lines 41 formed on the plate 10, which divide the plate 10 into a first region 42, a second region 43 and a third region 44, wherein the second region 43 is the optimal puncture area with the elbow crease as a reference.

[0052] The partition lines 41 on the tablet 10 divide the surface of the tablet 10 into three distinct areas. Medical staff can quickly distinguish the functions of different areas based on the position of the patient's arm using the partition lines 41. The partition lines 41 provide an intuitive visual reference for identifying the puncture area, avoiding puncture position deviations caused by unclear area judgment during puncture operations. This helps medical staff quickly locate the relevant puncture area, improves the efficiency of puncture preparation, and lays the foundation for subsequent accurate puncture. Using the clear physiological landmark of the elbow crease as a reference, the second area 43 on the tablet 10 is defined as the optimal puncture area. This allows medical staff to quickly and accurately match the optimal puncture site of the patient's arm to the second area 43 of the tablet 10, reducing the time and error in judging the optimal puncture area. This ensures that the puncture operation is always performed in the optimal area, effectively improving the puncture success rate and reducing the risk of complications such as vascular damage and catheter displacement caused by improper puncture position.

[0053] like Figures 1 to 7 As shown, the clamping assembly 50 includes two sets of mounting blocks 51 respectively fixedly installed on both sides of the plate 10. Each set of mounting blocks 51 includes two mounting blocks 51 arranged opposite each other on the same side of the plate 10. A rotating shaft 52 is rotatably installed between the two mounting blocks 51 on the same side. A pair of sleeves 53 are fixedly installed on the rotating shaft 52. A movable rod 54 is slidably installed inside the sleeve 53. An installation rod 55 is fixedly installed between the two movable rods 54 on the same side. A clamp 56 is fixedly installed on the installation rod 55. A spring piece 57 is fixedly installed on the sleeve 53. The other end of the spring piece 57 is fixedly connected to the plate 10.

[0054] Patients often experience rapid weight loss during punctures, resulting in loose, sagging skin on their arms. To address this, the sleeve 53 is rotated to the appropriate angle. As the sleeve rotates, it compresses the spring 57. The clamp 56 is then placed on the loose skin on either side of the optimal puncture area. Releasing the sleeve 53 causes the spring 57 to rotate the sleeve 53 and the pivot 52. Simultaneously, the movable rod 54, sliding within the sleeve 53, adapts to different arm sizes, effectively stretching the loose skin, improving the clarity of the puncture field, and reducing the difficulty of the puncture. Specifically, the movable rod 54 slides within the sleeve 53; that is, as the clamp 56 rotates while gripping the skin, the movable rod 54 slides within the sleeve 53, allowing for adaptive length adjustment.

[0055] like Figure 2As shown, a fixing component 60 is provided on the flat plate 10. The fixing component 60 includes a first sliding plate 61 slidably installed inside the flat plate 10, a second sliding plate 62 slidably installed inside the first sliding plate 61, a protruding plate 65 fixedly installed on the second sliding plate 62, a lifting rod 66 slidably installed on the protruding plate 65, a second spring 68 sleeved and fixedly installed on the lifting rod 66, the other end of the second spring 68 being fixedly connected to the protruding plate 65, and a fixing plate 67 fixedly installed at the bottom end of the lifting rod 66. The fixing plate 67 is located below the protruding plate 65, and the fixing plate 67 and the protruding plate 65 cooperate to clamp the side of the hospital bed.

[0056] First, slide the first slide plate 61 and the second slide plate 62 within the first slide plate 61 inside the flat plate 10 to adjust the horizontal position of the convex plate 65 so that the convex plate 65 can be aligned with the edge of the hospital bed. Then, drive the lifting rod 66 to move the fixing plate 67 downward, compressing the second spring 68 and pressing the convex plate 65 against the upper edge of the hospital bed. Release the lifting rod 66, and the second spring 68, under the action of elastic restoring force, pulls the lifting rod 66 and the fixing plate 67 upward, so that the fixing plate 67 and the convex plate 65 cooperate to clamp the edge of the hospital bed, thereby fixing the auxiliary frame to the hospital bed. It can be adapted to hospital beds of different widths. The cooperation between the lifting rod 66 and the second spring 68 realizes the rapid clamping and releasing of the fixing plate 67. The fixing method is firm and reliable, providing a stable support environment for puncture operations.

[0057] The plate 10 is threaded with a first fixing bolt 63, one end of which can abut against the first sliding plate 61. The first sliding plate 61 is threaded with a second fixing bolt 64, one end of which can abut against the second sliding plate 62.

[0058] After adjusting the position of the protruding plate 65 using the first sliding plate 61 and the second sliding plate 62, tighten the first fixing bolt 63 on the plate 10 so that one end of the first fixing bolt 63 is tightly pressed against the first sliding plate 61, fixing the relative position of the first sliding plate 61 and the plate 10 through friction. At the same time, tighten the second fixing bolt 64 on the first sliding plate 61 so that one end of the second fixing bolt 64 is pressed against the second sliding plate 62, fixing the relative position of the second sliding plate 62 and the first sliding plate 61. This effectively locks the positions of the first sliding plate 61 and the second sliding plate 62, preventing the sliding plates from sliding due to external forces during the use of the auxiliary frame, ensuring the stable and reliable fixing effect of the fixing component 60, further ensuring the overall stability of the auxiliary frame, and providing safety for piercing operations.

[0059] like Figure 8As shown, a pressing assembly 70 is provided on the flat plate 10. The pressing assembly 70 includes a rotating rod 71 rotatably mounted on the flat plate 10. A top plate 72 is fixedly mounted on the rotating rod 71. A movable cylinder 73 is fixedly mounted on the top plate 72. The movable cylinder 73 passes through the top plate 72. A pull rod 76 is slidably mounted inside the movable cylinder 73. A pressing sponge 75 is fixedly mounted at the bottom end of the pull rod 76. The pressing sponge 75 is located below the top plate 72 and protrudes outside the movable cylinder 73. A third spring 74 is fixedly mounted on the pressing sponge 75. The third spring 74 is sleeved on the pull rod 76. The other end of the third spring 74 is fixedly connected to the inner wall of the movable cylinder 73.

[0060] Before and after puncture, rotate the rotating rod 71 to adjust the top plate 72, movable cylinder 73, pull rod 76, and pressure sponge 75 to the position on the patient's arm that needs to be pressed. Pull the pull rod 76 to adjust the height of the pressure sponge 75 so that it fits the target area on the patient's arm. The third spring 74 provides elastic support between the pressure sponge 75 and the movable cylinder 73. Under the elastic force of the third spring 74, the pressure sponge 75 applies gentle and stable pressure to the patient's arm. This pressure helps the pressure sponge 75 to press firmly on the wound, reduce bleeding, meet the pressing needs of different patients and puncture scenarios, and improve the stability and safety of the puncture operation.

[0061] A Velcro strap 11 is fixedly installed on the flat plate 10, and a pressure sensor is provided on the Velcro strap 11.

[0062] After placing the patient's arm on the tablet 10, the Velcro strap 11 is wrapped around and secured to the arm, preventing movement during the puncture and ensuring a smooth procedure. The Velcro strap 11 is easy to apply and its tightness can be adjusted according to the patient's arm size. Simultaneously, a pressure sensor on the Velcro strap 11 monitors the pressure exerted on the patient's arm in real time and transmits this data to medical staff. The staff can then adjust the tightness of the strap to ensure effective fixation without excessive pressure that could impede blood circulation or cause discomfort, thus improving patient comfort and the safety of the puncture procedure.

[0063] A storage cavity 80 is provided on one side of the plate 10 for storing a transparent sterile plastic sleeve. The transparent sterile plastic sleeve is used to cover the plate 10, the pressing sponge 75 and the clip 56 to reduce the contact between the device and the patient's skin, ensure sterility during the treatment process, and maintain hygiene and treatment effectiveness.

[0064] The working process of the multifunctional automatic PICC catheter puncture auxiliary frame provided by this invention is as follows:

[0065] In traditional treatment, patients lie flat on the bed, and medical staff need to use probes to perform punctures on the optimal puncture area. After a long time, the staff will feel uncomfortable. The tablet 10, as the basic load-bearing structure of the entire auxiliary frame, provides an installation and support platform for various functional components. When the patient's arm is placed on the tablet 10 for treatment, medical staff do not need to use probes, which reduces the pressure on medical staff and improves the treatment effect.

[0066] The measuring component 20, in conjunction with the synchronization component 30, can accurately locate the optimal puncture area of ​​the patient's arm and measure the arm circumference of that area, providing data for selecting the appropriate PICC catheter size and avoiding puncture failure or postoperative complications caused by mismatch between catheter size and arm circumference.

[0067] The partitioning component 40 can clearly divide the relevant areas of the patient's arm for puncture, helping medical staff to quickly identify the best puncture area, reduce puncture positioning time, and improve puncture efficiency;

[0068] The clamping component 50 can clamp and stretch the loose skin at the puncture site on the patient's arm, making the blood vessels at the puncture site more clearly exposed, reducing the risk of blood vessel damage during puncture, and reducing the interference of skin folds on the puncture operation, thereby improving the accuracy and success rate of puncture.

[0069] When it is necessary to measure the arm circumference of the optimal puncture area of ​​the patient's arm, the positions of the first protrusion 21 and the second protrusion 28 are adjusted by the synchronization component 30, and the measuring belt 25 is pulled to release it from the take-up shaft 23 inside the first protrusion 21. At this time, the take-up shaft 23 rotates and the torsion spring 24 undergoes elastic deformation. After the measuring belt 25 is wrapped around the optimal puncture area of ​​the patient's arm, the hook 27 on the measuring belt 25 is hooked onto the limiting hook 26 of the second protrusion 28. The arm circumference data can then be read through the scale of the measuring belt 25. After the measurement is completed, the hook 27 is released, and the torsion spring 24 drives the take-up shaft 23 to rotate in the opposite direction under the action of elastic restoring force, automatically retracting the measuring belt 25 and winding it onto the take-up shaft 23, realizing the storage and reset of the measuring belt 25. The operation is simple, the measurement is accurate, and the efficiency and accuracy of arm circumference measurement are improved.

[0070] When adjusting the positions of the first protrusion 21 and the second protrusion 28 within the slide groove 31 of the flat plate 10, the first toothed plate 32 on the first protrusion 21 and the second toothed plate 33 on the second protrusion 28 will synchronously drive the intermediate gear 35 to rotate, ensuring that the first protrusion 21 and the second protrusion 28 always move symmetrically around the gear 35, ensuring that the measuring band 25 is always aligned with the measurement area of ​​the patient's arm, and can adapt to arms of different thicknesses, improving measurement accuracy. When it is necessary to fix the positions of the first protrusion 21 and the second protrusion 28, the electromagnet 37 is energized, and the electromagnet 37 generates magnetic force to attract the magnetic block 39, causing the magnetic block 39 to compress the first spring 38 and drive the limiting block 310 to move. The limiting block 310 simultaneously engages with the first limiting slot in the cavity 36 of the gear 35. The gear 35 is fixed by the second limiting slot 312 on the plate 10 and the gear 311. The first boss 21 and the second boss 28 are fixed by the meshing relationship between the gear 35 and the first tooth plate 32 and the second tooth plate 33. When the position needs to be adjusted again, the power supply of the electromagnet 37 is cut off, the magnetic force of the electromagnet 37 disappears, and the first spring 38 pushes the magnetic block 39 to reset under the action of elastic restoring force, which drives the limiting block 310 to disengage from the first limiting slot 311. The gear 35 resumes rotation. At this time, the position of the first boss 21 and the second boss 28 can be slid and adjusted again, realizing the synchronous movement and precise positioning of the first boss 21 and the second boss 28, ensuring the measurement accuracy of the measuring component 20, and at the same time, the operation is flexible and convenient, improving the ease of use of the auxiliary frame.

[0071] The partition lines 41 on the tablet 10 divide the surface of the tablet 10 into three distinct areas. Medical staff can quickly distinguish the functions of different areas based on the position of the patient's arm using the partition lines 41. The partition lines 41 provide an intuitive visual reference for identifying the puncture area, avoiding puncture position deviations caused by unclear area judgment during puncture operations. This helps medical staff quickly locate the relevant puncture area, improves the efficiency of puncture preparation, and lays the foundation for subsequent accurate puncture. Using the clear physiological landmark of the elbow crease as a reference, the second area 43 on the tablet 10 is defined as the optimal puncture area. This allows medical staff to quickly and accurately match the optimal puncture site of the patient's arm to the second area 43 of the tablet 10, reducing the judgment time and error of medical staff in determining the optimal puncture area. This ensures that the puncture operation is always performed in the optimal area, effectively improving the puncture success rate and reducing the risk of complications such as vascular damage and catheter displacement caused by improper puncture position.

[0072] Patients often experience rapid weight loss during puncture, resulting in loose, sagging skin on their arms. When using this device, rotate the sleeve 53 to the appropriate angle. As the sleeve 53 rotates, it compresses the spring 57. Then, clamp the clip 56 onto the loose skin on both sides of the optimal puncture area. After releasing the sleeve 53, the spring 57 drives the sleeve 53 and the rotating shaft 52 to rotate. Simultaneously, the movable rod 54, sliding within the sleeve 53, adapts to different arm sizes, allowing for adaptive adjustments. This effectively stretches the loose skin, improves the clarity of the puncture field, and reduces the difficulty of the puncture.

[0073] First, slide the first slide plate 61 and the second slide plate 62 inside the first slide plate 61 within the first slide plate 61 to adjust the horizontal position of the convex plate 65 so that the convex plate 65 can be aligned with the edge of the hospital bed. Then, pull the lifting rod 66 to move the fixing plate 67 downward. The second spring 68 is compressed, causing the convex plate 65 to fit against the edge of the hospital bed. Release the lifting rod 66, and the second spring 68, under the action of elastic restoring force, pulls the lifting rod 66 and the fixing plate 67 upward, so that the fixing plate 67 and the convex plate 65 cooperate to clamp the edge of the hospital bed, thereby fixing the auxiliary frame to the hospital bed. It can be adapted to hospital beds of different widths. The cooperation between the lifting rod 66 and the second spring 68 enables the quick clamping and loosening of the fixing plate 67. The fixing method is firm and reliable, providing a stable support environment for puncture operations.

[0074] After adjusting the position of the convex plate 65 using the first slide plate 61 and the second slide plate 62, tighten the first fixing bolt 63 on the plate 10 so that one end of the first fixing bolt 63 abuts tightly against the first slide plate 61, fixing the relative position of the first slide plate 61 and the plate 10 by friction. At the same time, tighten the second fixing bolt 64 on the first slide plate 61 so that one end of the second fixing bolt 64 abuts against the second slide plate 62, fixing the relative position of the second slide plate 62 and the first slide plate 61. This effectively locks the positions of the first slide plate 61 and the second slide plate 62, preventing the slide plates from sliding due to external forces during the use of the auxiliary frame, ensuring the stable and reliable fixing effect of the fixing component 60, further ensuring the overall stability of the auxiliary frame, and providing safety for the piercing operation.

[0075] Before and after puncture, rotate the rotating rod 71 to adjust the top plate 72, movable cylinder 73, pull rod 76, and pressure sponge 75 to the position on the patient's arm where pressure is needed. Pull the pull rod 76 to adjust the height of the pressure sponge 75 so that it fits the target area on the patient's arm. The third spring 74 provides elastic support between the pressure sponge 75 and the movable cylinder 73. Under the elastic force of the third spring 74, the pressure sponge 75 applies gentle and stable pressure to the patient's arm. This pressure helps the pressure sponge 75 to press firmly on the wound, reducing bleeding and meeting the pressure needs of different patients and puncture scenarios, thus improving the stability and safety of the puncture operation. When pressure is not needed, pull the pull rod 76 upward to move the pressure sponge 75 away from the puncture point, and then rotate the rotating rod 71 to move the entire assembly away.

[0076] After placing the patient's arm on the tablet 10, the Velcro strap 11 is wrapped around and secured to the arm, preventing movement during the puncture and ensuring a smooth procedure. The Velcro strap 11 is easy to apply and its tightness can be adjusted according to the patient's arm size. Simultaneously, a pressure sensor on the Velcro strap 11 monitors the pressure exerted on the patient's arm in real time and transmits this data to medical staff. The staff can then adjust the tightness of the strap to ensure effective fixation without excessive pressure that could impede blood circulation or cause discomfort, thus improving patient comfort and the safety of the puncture procedure.
