Description

Technical Field

[0001] This invention relates to the field of cardiovascular interventional technology, specifically to a treatment device for cardiovascular interventional surgery. Background Technology

[0002] After a vascular interventional procedure, staff need to apply pressure to the puncture site for an extended period of time.

[0003] A search revealed that Chinese Patent Publication No. CN214907553U discloses a compression hemostasis and fixation device after puncture in cardiovascular interventional surgery, relating to the field of compression medical equipment technology. The main frame has a groove, and both sides of the groove have medium-sized grooves. The groove is located between and connected to the two medium-sized grooves. A lateral adjustment mechanism is installed within the groove. The sliding end of the lateral adjustment mechanism is located within the medium-sized groove, and the moving end of the lateral adjustment mechanism has a sliding groove. The sliding groove has equidistantly arranged locking grooves, and a height adjustment mechanism is installed within the sliding groove. This invention, a compression hemostasis and fixation device after puncture in cardiovascular interventional surgery, uses fastening bolts to fix the main frame to the patient's bedside or other location. Medical personnel can adjust the compression mechanism according to the patient's puncture location, facilitating pressure application to the puncture site and allowing for control of the compression pressure, avoiding inconsistent application of force.

[0004] However, the existing technical solutions mentioned above are mainly used to apply pressure to the puncture site of the patient to solve the problem of the pressure intensity. Since the puncture site is exposed to the air for a long time, it is easy for the patient's arm or hand to get cold, causing discomfort to the patient. Therefore, a treatment device for cardiovascular interventional surgery is needed. Summary of the Invention

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides a treatment device for cardiovascular interventional surgery, which has the following beneficial effects:

[0032] The servo motor in this invention can drive the active gear to rotate, and the active gear can drive the coaxial gear and the movable worm to rotate synchronously. The two parts of the movable worm and the two movable worm wheels are symmetrically distributed. The movable worm wheels mesh with the corresponding parts of the movable worm. The movable worm can drive the movable worm wheels and the movable clamping plate to rotate along the axis, which can change the rotation angle of the movable clamping plate. The two movable clamping plates can hold the patient's arm and fix the patient's arm on the arm support.

[0033] In this invention, external gas can flow into the air intake box through the action of the air intake fan. The gas is filtered through multiple layers by several activated carbon perforated plates, which can reduce the impurities carried by the gas. The filtered gas is then sent into the heating box through the vent.

[0034] In this invention, the patient's arm is placed on an arm support. The hollow movable column at the bottom of the arm support compresses the support spring inside the hollow connecting column. The support spring provides elastic support for the hollow movable column and the arm support, thereby providing elastic support for the patient's arm.

[0035] The heating chamber of this invention has several heating wires inside, which can be used to heat the gas. The heated gas can be sent into the first air chamber through the connecting pipe and the first air hole, and then into the second air chamber through the second air hole. The heated gas can also be dispersed into several third air chambers and then discharged through the third air holes. This can effectively disperse the heated gas on the arm support, providing effective and uniform heating for the patient's arm, preventing the arm from being exposed to the air for a long time and providing heating protection. The heated gas can also be sent into the fourth air chamber through the hose and then dispersed and discharged through several fourth air holes. The heated gas discharged from the movable clamps on both sides through the several fourth air holes blows onto the arm placed on the arm support, which can increase the heating range of the patient's arm, providing heating treatment for the patient's arm and also providing wrapping heating treatment for the patient's arm.

[0036] This invention provides support for the patient's arm and uses movable clamps on both sides to hold the patient's arm. A first electric cylinder slowly pushes the connecting plate downwards, while simultaneously pushing the connecting head and the pressing head to press on the puncture site. After the pressing head presses on the puncture site, it squeezes the pressure sensor upwards. The pressure value detected by the pressure sensor is displayed on the screen. When the pressure reaches a certain range, the first electric cylinder is turned off, so that the pressing head presses on the puncture site with a certain pressure and provides a wrapping-like heating treatment for the patient's arm.

[0049] 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.

[0050] Please see Figures 1-11 A treatment device for cardiovascular interventional surgery includes a bed 1 and a pressing assembly. A stabilizing frame 19 is provided at the front end of the bed 1. A sliding hole is provided on the moving plate 15. The stabilizing frame 19 is slidably connected to the sliding hole. The stabilizing frame 19 can improve the stability of the moving plate 15 and the U-shaped frame 2. The pressing assembly is used to press the puncture site. The pressing assembly includes a U-shaped frame 2, a first electric cylinder 3, two sets of guide rods 4, a connecting plate 5, a connecting head 6, and a pressing head 7. The first electric cylinder 3 is fixedly installed at the top of the U-shaped frame 2. Both sets of guide rods 4 are slidably connected to the top of the U-shaped frame 2. The top of the connecting plate is connected to the output end of the first electric cylinder 3 and the bottom end of the two sets of guide rods 4. The connecting head 6 is fixedly installed on the connecting plate. A first groove is provided on the connecting head 6. A pressure sensor 8 is provided at the top of the first groove. A display screen 9 is provided at the top of the U-shaped frame 2. The pressure sensor 8 is electrically connected to the display screen 9. The pressing head 7 is slidably engaged with the first groove. The top of the pressing head 7 is attached to the bottom end of the pressure sensor 8.

[0051] By adopting the above technical solution, the U-shaped frame 2 is adjusted to the left and right position on the hospital bed 1 by the moving component. When the patient is lying down and pressure is needed after puncture at the wrist, the wrist is placed in the U-shaped frame 2, and the first electric cylinder 3 is activated to slowly push the connecting plate downward. At the same time, the connecting head 6 and the pressing head 7 are pushed to press the puncture site. After the pressing head 7 presses the puncture site, it squeezes the pressure sensor 8 upward. The pressure value detected by the pressure sensor 8 is displayed on the display screen 9. When the pressure reaches a certain range, the first electric cylinder 3 is turned off, so that the pressing head 7 presses the puncture site with a certain pressure. The clamping component can clamp and limit the wrist on both sides, reducing the wrist's mobility. Therefore, a treatment device for cardiovascular interventional surgery is provided that can accurately control the pressure of pressing the puncture site in cardiovascular interventional surgery and improve the pressing effect of the pressing site.

[0052] Please see Figures 1-3 The clamping assembly consists of two sets symmetrically arranged front and rear. The clamping assembly is used to clamp and limit the wrist. It includes a multi-stage second electric cylinder 10 and a clamping plate 11. A sponge pad 17 is provided on the clamping plate 11 to improve the comfort of the pierced wrist. The multi-stage second electric cylinder 10 is fixedly mounted on a connecting plate, which has a U-shaped groove. The clamping plate 11 is slidably connected to the U-shaped groove and is connected to the output end of the multi-stage second electric cylinder 10. Activating the multi-stage second electric cylinder 10 moves the clamping plate 11 closer to the wrist and clamps and limits the pierced wrist.

[0053] Please see Figure 1 and Figure 2 The movable component is installed at the bottom of the bed 1 and is used to adjust the position of the U-shaped frame 2. The movable component includes two sets of fixed plates 12, a lead screw 13, two sets of sliding rods 14, and a movable plate 15. The two sets of fixed plates 12 are fixedly installed at the bottom of the bed 1. The lead screw 13 is rotatably connected to the two sets of fixed plates 12. One set of fixed plates 12 is equipped with a motor 16. The output end of the motor 16 is connected to the lead screw 13. Starting the motor 16 can drive the lead screw 13 to rotate. The two ends of the two sets of sliding rods 14 are respectively connected to the inner ends of the two sets of fixed plates 12. The lead screw 13 is connected to the movable plate 15. Both sets of sliding rods 14 are slidably connected to the movable plate 15. The movable plate 15 is fixedly connected to the bottom of the U-shaped frame 2. The movable plate 15 moves on the two sets of sliding rods 14 by rotating the lead screw 13. The position of the U-shaped frame 2 is adjusted according to the patient's position by moving the U-shaped frame 2 left and right.

[0054] like Figure 4 and Figure 5As shown, a platform 18 is provided on the U-shaped frame 2, and an arm support assembly is provided on the platform 18. The arm support assembly is used to clamp and support the arm. The arm support assembly includes a support bracket 20 that is bolted to the platform 18. The support bracket 20 has an open movable cavity 21 inside, and air inlet cavities 22 located on both sides of the movable cavity 21. A heating box 32 is provided at the bottom inside the movable cavity 21, and an air inlet box 34 is provided inside the air inlet cavity 22. A ventilation port 33 is connected between the heating box 32 and the air inlet box 34.

[0055] like Figure 4 , Figure 5 and Figure 9 As shown, an arm support 23 is provided above the support bracket 20, and movable clamping plates 24 are located on both sides of the arm support 23. The bottom of the movable clamping plate 24 is connected to a movable worm gear 25. The movable clamping plate 24 and the movable worm gear 25 are movably connected to the support bracket 20 through a shaft. The bottom of the movable worm gear 25 meshes with a movable worm 26. The input shaft of the movable worm 26 is fixed with a coaxial gear 27. The coaxial gear 27 meshes with a drive gear 28. The input shaft of the drive gear 28 is fixed with a servo motor 29.

[0056] By adopting the above technical solution, the patient's arm can be placed on the arm support 23. Then, the servo motor 29 can drive the drive gear 28 to rotate. The drive gear 28 can drive the coaxial gear 27 and the movable worm gear 26 to rotate synchronously. The two parts of the movable worm gear 26 and the two movable worm wheels 25 are symmetrically distributed. The movable worm wheels 25 mesh with the corresponding parts of the movable worm gear 26. The movable worm gear 26 can drive the movable worm wheels 25 and the movable clamping plate 24 to rotate along the axis, which can change the rotation angle of the movable clamping plate 24. The two movable clamping plates 24 can clamp the patient's arm and fix the patient's arm on the arm support 23.

[0057] like Figure 4 and Figure 6As shown, a movable filter cylinder 35 is installed on one side inside the air inlet box 34. The movable filter cylinder 35 has several filter holes 36 inside. Connecting sliders 37 are fixed to both sides of the outer wall of the movable filter cylinder 35. Limiting grooves 38 are provided on both sides of the inner wall of the air inlet box 34. The connecting sliders 37 are partially adapted to the limiting grooves 38, allowing the movable filter cylinder 35 to move. The connecting sliders 37 on both sides of the movable filter cylinder 35 can move within the limiting grooves 38. The limiting grooves 38 restrict the movement trajectory of the connecting sliders 37, and the connecting sliders 37 and the limiting grooves 38 restrict the range of motion of the movable filter cylinder 35. The movable filter cylinder 35 can be moved through the air inlet box 34. Pulling out the internal part of 4 exposes several filter holes 36 on the air inlet box 34 to the air, increasing the air intake area. Alternatively, the movable filter tube 35 can be pushed into the air inlet box 34, providing preliminary filtration of the gas through the filter holes 36, reducing impurities carried by the gas. The air inlet box 34 is equipped with an air intake fan 39 and several activated carbon perforated plates 40. Several slots 41 are provided at the bottom of the inner wall of the air inlet box 34. The bottom of the activated carbon perforated plates 40 can be inserted into the slots 41, allowing several activated carbon perforated plates 40 to be installed inside the air inlet box 34.

[0058] By adopting the above technical solution, external gas can flow into the air inlet box 34 through the action of the air intake fan 39. The gas is filtered through multiple layers by several activated carbon perforated plates 40, which can reduce the impurities carried by the gas. The filtered gas is then sent into the heating box 32 through the vent 33.

[0059] like Figure 4 and Figure 7 As shown, the heating box 32 has several heating wires 42 inside. The top of the heating box 32 is connected to a hollow connecting column 31. A hollow movable column 30 passes through the top of the hollow connecting column 31. A support spring 46 is installed inside the hollow connecting column 31. A connecting tube 45 passes through the inside of the support spring 46. The patient's arm is placed on the arm support 23. The hollow movable column 30 at the bottom of the arm support 23 compresses the support spring 46 inside the hollow connecting column 31. The support spring 46 provides elastic support for the hollow movable column 30 and the arm support 23, thereby providing elastic support for the patient's arm.

[0060] like Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the hollow movable column 30 has a first air chamber 43 inside, and a first air hole 44 is opened at the bottom of the first air chamber 43. The heating box 32 is connected to the first air chamber 43 through the connecting pipe 45 and the first air hole 44. A second air hole 47 is opened at the top of the first air chamber 43. The arm support 23 has a second air chamber 48 inside, as well as several third air chambers 49. A third air hole 50 is opened at the top of the third air chamber 49. The first air chamber 43, the second air hole 47, the second air chamber 48, the third air chamber 49 and the third air hole 50 are connected.

[0061] By adopting the above technical solution, several heating wires 42 inside the heating box 32 can be used to heat the gas. The heated gas can be sent into the first air chamber 43 through the connecting pipe 45 and the first air hole 44, and then sent into the second air chamber 48 through the second air hole 47. The heated gas can also be dispersed into several third air chambers 49 and then discharged through the third air hole 50. The heated gas can be effectively dispersed on the arm support 23. The heated gas can be used to provide effective and dispersed heating for the patient's arm and to provide uniform heating for the patient's arm. This can prevent the arm from being exposed to the air for a long time and thus provide heating protection for the patient's arm.

[0062] like Figure 4 As shown, both sides of the hollow movable column 30 are connected to hoses 51. The movable clamp 24 has a fourth air chamber 52 inside. The fourth air chamber 52 has several fourth air holes 53 inside. The first air chamber 43 of the hollow movable column 30 is connected to the fourth air chamber 52 through hoses 51. The several fourth air holes 53 are evenly distributed in an arc shape.

[0063] By adopting the above technical solution, the heating gas can be sent into the interior of the fourth air chamber 52 along the hose 51, and then the heating gas is dispersed and discharged through several fourth air holes 53. The heating gas discharged from the movable clamps 24 on both sides through several fourth air holes 53 is blown onto the arm placed on the arm support 23, which can increase the heating range of the patient's arm, provide heating treatment for the patient's arm, and also provide wrapping heating treatment for the patient's arm.

[0064] In summary, when using this treatment device for cardiovascular interventional surgery, the starter motor 16 drives the lead screw 13 to rotate. The rotation of the lead screw 13 causes the moving plate 15 to move on the two sets of slide rods 14, which in turn moves the U-shaped frame 2 left and right to adjust its position according to the patient's position. When the patient is lying down, and pressure is needed after puncture at the wrist, the wrist is placed inside the U-shaped frame 2, and the patient's arm is placed on the arm support 23. The hollow movable column 30 at the bottom of the arm support 23 compresses the support spring 46 inside the hollow connecting column 31. The hollow movable column 30 and arm support 23 are provided with elastic support. Then, the servo motor 29 can drive the drive gear 28 to rotate. The drive gear 28 can drive the coaxial gear 27 and the movable worm 26 to rotate synchronously. The two parts of the movable worm 26 and the two movable worm wheels 25 are symmetrically distributed. The movable worm wheels 25 mesh with the corresponding parts of the movable worm 26. The movable worm 26 can drive the movable worm wheels 25 and the movable clamp 24 to rotate along the axis. The two movable clamps 24 can clamp the patient's arm, fix the patient's arm on the arm support 23, and support the patient's arm through the extension plate 18.

[0065] Secondly, the bottom of the activated carbon perforated plate 40 can be inserted into the slot 41, and several activated carbon perforated plates 40 can be installed inside the air inlet box 34. The movable filter tube 35 is pushed into the air inlet box 34, and the gas is provided with preliminary filtration through several filter holes 36 on the air inlet box 34. Then, through the action of the air intake fan 39, the external gas can flow into the air inlet box 34, and the gas is provided with multi-layer filtration through several activated carbon perforated plates 40, which can reduce the impurities carried by the gas. The filtered gas is then sent into the heating box 32 through the vent 33.

[0066] Secondly, several heating wires 42 inside the heating chamber 32 can be used to heat the gas. The heated gas can be sent into the first gas chamber 43 through the connecting pipe 45 and the first gas hole 44, and then sent into the second gas chamber 48 through the second gas hole 47. The heated gas can also be dispersed into several third gas chambers 49 and then discharged through the third gas hole 50. The heated gas can be used to heat the patient's arm and hand. Then, the heated gas can be sent into the fourth gas chamber 52 through the hose 51 and then dispersed and discharged through several fourth gas holes 53. This can increase the heating range of the patient's arm and provide heating treatment for the patient's arm, thus preventing the arm from being exposed to the air and getting cold for a long time.

[0067] Then, the first electric cylinder 3 is activated to slowly push the connecting plate downwards, while simultaneously pushing the connecting head 6 and the pressing head 7 to press against the puncture site. After the pressing head 7 presses against the puncture site, it squeezes the pressure sensor 8 upwards. The pressure value detected by the pressure sensor 8 is displayed on the display screen 9. When the pressure reaches a certain range, the first electric cylinder 3 is turned off, so that the pressing head 7 presses against the puncture site with a certain pressure. The multi-stage second electric cylinder 10 is activated to move the clamping plate 11 closer to the wrist and clamp and limit the punctured wrist, reducing the wrist's mobility.

[0068] This motor 16 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, which we will not elaborate on here. The motor 16 is equipped with a matching control switch, and the installation position of the control switch is selected according to actual usage requirements to facilitate operation and control by the operator.

[0069] The pressure sensor 8 and display screen 9 involved in this solution are products that already exist on the market. Their internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. Therefore, this patent will not elaborate on their internal structure and working principle.

[0070] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
