Description

Technical Field

[0001] The present invention relates to the field of interventional surgery nursing equipment, and in particular to an automated wound care device after interventional surgery. Background Art

[0002] Interventional therapy, also known as interventional medicine, is an emerging treatment approach between surgery and internal medicine. Based on imaging, interventional surgery is a relatively advanced minimally invasive technique that uses puncture needles, catheters, guidewires, and other recording equipment to diagnose and treat diseases, guided by devices such as X-rays, ultrasound, and CT scans. Its key advantages are minimal trauma, accurate positioning, and few complications, making it a key component of minimally invasive surgical techniques.

[0003] After the interventional treatment, the puncture point needs to be compressed for 15-20 minutes, and then a pressure bandage is applied. After the bandage, a 1kg sandbag is used to compress the puncture site. The arterial puncture is compressed for 6 hours, and the venous puncture is compressed for 2-4 hours. During this period, the sandbag cannot be shifted, and the puncture site needs to be closely observed for exudate, bleeding, and wound swelling. A small amount of bleeding and exudate should be replaced with a dressing in time, and an appropriate pressure bandage should be applied. At present, the compression before bandaging is mainly done manually, and this traditional method is undoubtedly labor-intensive and time-consuming. The current compression device, such as the utility model patent with publication number CN221083710U, is an interventional surgery artery compression nursing device.

The second latching protrusion 32 is bonded to the pressing post 20. The provision of the second latching groove 31 and the second latching protrusion 32 can secure the hand pressing plate 10, so that the hand pressing plate 10 will not easily separate from the pressing body 2 when using and operating the device.

[0037] A lever 33 is provided on the side of the skeleton ring 1 facing away from the skin. The lever 33 is bonded to the skeleton ring 1. A lever 34 is provided on the end of the pressing post 20 facing away from the hand pressing plate 10, extending horizontally between the lever 33 and the pressing post 20.

The lever 34 can pass through the second perforation 30. When replacing the pressing body 2, the support rod 34 can be pressed, and the hand pressing plate 10 and the frame ring 1 can be pressed. Then, the pressing body 2 can be pulled to separate the pressing body 2 from the frame ring 1. Then, the support rod 34 can be turned over to the extension line of the length direction of the pressing column 20, and the pressing body 2 can be slowly moved out so that the entire pressing body 2 passes through the pressing column 20 and the support rod 34. The installation of the support rod 34 makes operation more convenient.

[0038] To monitor the presence of exudate and bleeding, this embodiment includes a second outlet pipe 36 connected to the first outlet pipe 17.

[0039] The end of the fourth air outlet tube 39, remote from the second air outlet tube 36, enters the compression groove 6 and passes through the skin-facing side of the hand compression plate 10. A cotton ball 41 is inserted into the fourth air outlet tube 39 at the end remote from the second air outlet tube 36. If the dressing 12 becomes soaked with blood or exudate, the dressing 12 will soak the cotton ball 41. The portion of the fourth air outlet tube 39 located within the hand compression plate 10 is connected to the fourth air outlet tube 39. The fifth air outlet tube 42, which passes through the skin-facing side of the hand compression plate 10, passes through the compression groove 6 and the compression body 2, and then connects to the outside world.

[0040] The portions of the air outlet pipe 4 39 and the air outlet pipe 5 42 located within the pressing groove 6 each include a branch pipe 1 43 extending from the pressing body 2 and a branch pipe 2 44 extending into the hand pressing plate 10, with the end of the branch pipe 2 44 away from the branch pipe 1 43 being inserted into the hand pressing plate 10. An annular magnet 45 is provided on the outer periphery of the end of the branch pipe 1 43 near the branch pipe 2 44, and the annular magnet 45 is bonded to the outer wall of the branch pipe 1 43. An extension tube 46 is provided on the end of the branch pipe 2 44 near the branch pipe 1 43, and the extension tube 46 is bonded to the branch pipe 2 44. An annular iron sheet 47 is provided on the outer periphery of the end of the extension tube 46 away from the branch pipe 2 44, and the iron sheet 47 is bonded to the outer wall of the extension tube 46. The iron sheet 47 has two ends with insertion rods 48 on the side facing the second branch pipe 44. The insertion rods 48 are bonded to the iron sheet 47.

[0041] A wet-tight paper 53 is provided at the connection between the air outlet pipe 5 42 and the air outlet pipe 4 39 to completely block the air outlet pipe 5 42 . The wet-tight paper 53 is bonded to the air outlet pipe 5 42 and contacts the cotton 41 . When the cotton 41 is soaked, the cotton 41 will also slowly soak the wet-tight paper 53 .

[0042] The portion of the air outlet pipe five 42 located within the pressing body 2 is provided with an elastic rubber sheet 54 that completely blocks the air outlet pipe five 42. The elastic rubber sheet 54 is bonded to the air outlet pipe five 42. A horizontal plate 55 is provided on the side of the elastic rubber sheet 54 facing away from the pressing groove 6. The horizontal plate 55 is located within the air outlet pipe five 42 and does not completely block the air outlet pipe five 42. The horizontal plate 55 is bonded to the air outlet pipe five 42. A pressure sensing chip two 56 is provided on the side of the horizontal plate 55 facing the elastic rubber sheet 54.

[0043] The operating principle of this embodiment is as follows: after the interventional surgery, the device is set up through the control panel 3, and the device is pressed against the puncture site so that the hand pressure plate 10 is facing the puncture site. At this time, the pressing plate 8 and the hand pressure plate 10 of the device are both adhered with a dressing 12 on the side facing the skin. The pressure sensor chip 11 is squeezed and transmits the pressure value to the control panel 3. The control panel 3 controls the operation of the air pump 13, and at the same time opens the solenoid valve 16 and the solenoid valve 2 37, closes the solenoid valve 3 40, and the air pump 13 forms a negative pressure in the adsorption tank 5 through the air inlet pipe 14. The adsorption tank 5 automatically closes after being sucked onto the skin. The solenoid valve 16 at the air inlet pipe 14 is closed. At this time, the device is fixed to the patient through adsorption. Then the air pump 13 continues to inhale gas through the air inlet pipe 2 15. The spherical airbag 19 expands, pushing the pressing plate 8 toward the skin. The hand pressing plate 10 moves along with the pressing plate 8. At this time, the spring 1 27 and the spring 2 29 are stretched, the telescopic tube 46 is stretched, and the insertion rod 48 moves away from the skin relative to the vertical rod 49 until the value of the pressure sensor chip 11 reaches the set value, indicating that the pressure on the puncture site reaches the required pressure value, thereby achieving the purpose of compression and hemostasis.

[0044] After the pressure value is reached, the control panel 3 closes the electromagnetic valve 16 and the electromagnetic valve 2 37 at the air inlet pipe 2 15, so that the device remains in the pressed state; when the pressure value is too large, the air pump 13 can be deflated, and the spherical airbag 19 will retract. At this time, due to the elastic force of the spring 1 27 and the spring 2 29, the pressing plate 8 and the hand pressing plate 10 will be pulled away from the skin by the corresponding spring 1 27 and the spring 2 29; after that, the medical staff can leisurely tear off the protective paper 22 on the adhesive surface and fix the skeleton ring 1 to the patient's skin surface through the soft fixing patch 21. After fixing the skeleton ring 1, the control panel 3 controls the two electromagnetic valves 16 to open, the negative pressure in the adsorption groove 5 disappears, the adsorption groove 5 is no longer adsorbed on the skin surface, and the soft fixing patch 21 is used to fix the device on the patient's skin, which can prevent the adsorption groove 5 from adsorbing the skin for a long time and damaging the skin;

[0045] After pressing for 15-20 minutes, before bandaging, press the frame rod 34, pinch the two convex plates 57, and lift the pressing body 2 in the direction away from the patient's skin. After the pressing body 2 and the skeleton ring 1 are loosened, the frame rod 34 is flipped over so that the frame rod 34 is flipped to the extension line of the length direction of the pressing column 20 through the frame rod 34, and the pressing body 2 continues to move in the direction away from the patient. When the pressing body 2 is far enough away from the hand pressing plate 10, the top of the hand pressing plate 10 can be directly pressed by hand to remove the pressing body 2 from the pressing column 20 and the frame rod 34; during the above operation, the insertion rod 48 moves with the slider 2 52 in the direction away from the skin. When the slider 2 52 moves to the end of the slide groove 2 51 away from the skin, the insertion rod 48 can no longer move. At this time, the pressing body 2 is continued to be lifted upward, and the annular magnet 45 and the iron sheet 47 are forced to separate. At this point, the pressing body 2 is completely separated from the hand pressing plate 10;

[0046] Then tear off the dressing 12 on the removed pressing plate 8 and stick on a clean dressing 12, then take a clean hand pressing plate 10 with a dressing 12 attached, and install the hand pressing plate 10 on the removed pressing body 2 through the second perforation 30, then quickly take away the hand pressing plate 10 pressing on the patient, install the pressing body 2 and the hand pressing plate 10 with the dressing 12 attached into the skeleton ring 1 on the patient, and continue to press the wound with the pressing plate 8 and the hand pressing plate 10; when replacing the dressing 12, also follow the above operation, directly tear off the previous dressing 12 on the pressing plate 8 and the hand pressing plate 10, and stick on a new dressing 12;

[0047] During the compression process, when the pressure value of the pressure sensor chip 11 exceeds a certain range, it indicates that the skin around the puncture site is swollen, and the control panel 3 will then prompt the swelling. At the same time, during the compression process, the air pump 13 will periodically open the solenoid valve 16 at the second inlet pipe 15 and the solenoid valve 3 40 at the second outlet pipe 36, and keep the solenoid valve 2 37 in the closed state. The air pump 13 runs, blowing gas into the second outlet pipe 36, the third outlet pipe 38, and the fourth outlet pipe 39 at a relatively low pressure. Since the cotton 41 and the easy-to-wet paper 53 block the fifth outlet pipe 42 and the fourth outlet pipe 39, the gas mainly exits from the third outlet pipe 38. At this time, the value of the pressure sensor chip 2 56 will not change, indicating that there is no exudate or bleeding.

[0048] When exudation or bleeding occurs at the puncture site, the liquid will soak the dressing 12, the dressing 12 will further soak the cotton 41, and the cotton 41 will soak the easy-to-wet paper 53. At this time, the air pump 13 will blow gas into the second outlet pipe 36, the third outlet pipe 38 and the fourth outlet pipe 39 according to the previous pressure value. The gas will break through the wet easy-to-wet paper 53 and enter the fifth outlet pipe 42. The gas will blow the elastic rubber sheet 54 toward the horizontal plate 55 to swell up. The elastic rubber sheet 54 squeezes the pressure sensor chip 2 56 on the horizontal plate 55.
