Description

Technical Field

[0001] The present invention relates to the technical field of pressure bandaging, and in particular to a pressure bandaging device after breast surgery. Background Art

[0002] After surgical removal of breast tissue, a certain cavity will be left, namely the dead space. Pressure bandage can make the skin fit closely with deep tissue, reduce the dead space, allow new blood vessels, fibrous tissue, etc. to better fill it, and promote healing. Traditional pressure bandage methods, such as using elastic bandages or chest straps, can provide a certain amount of pressure support, but have many shortcomings.

[0003] For example, Chinese patent CN220046294U discloses a breast surgery pressure bandage device, including a shoulder strap, the bottom of the shoulder strap is fixedly connected to the device body, one side of the middle front of the main vest is fixedly connected to the chest connecting buckle, the other side of the middle front of the main vest is fixedly connected to the chest connecting strip, and the middle of the back of the main vest is fixedly connected to the back connecting buckle; by setting the back connecting buckle, it is ensured that the back of the device can be freely opened to facilitate the user to put it on while ensuring the stability of the connection after putting it on; by setting the back connecting strip, the connection of the back of the device is ensured, and the back connecting strip has no direct connection with the main vest, which can increase the expansion area of the back; and the connection characteristics of the back connecting strip and the back connecting buckle can facilitate the free manipulation of the expansion surface of the back of the device without excessive operation.

[0004] However, this technology has the following problems: First, relying solely on shoulder straps, the main vest, and simple connecting parts may result in uneven force on different parts of the chest, affecting the effectiveness of hemostasis and swelling reduction. It may even cause tissue damage due to excessive local pressure, or insufficient local pressure to effectively promote healing.

[0005] Second, it cannot meet the different pressure requirements of different patients and recovery stages after breast surgery. The fixed connection method is difficult to meet the personalized pressure adjustment needs, affecting the treatment effect.

DETAILED DESCRIPTION

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0042] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-11 A postoperative breast surgery pressure bandage device includes a wearable body 1, a bandage mechanism 2, a pressure fine-tuning component 3, and a drainage limiter module 4. The interior of the wearable body 1 is connected to the bandage mechanism 2, the bandage mechanism 2 is equipped with the pressure fine-tuning component 3, and the lower end of the wearable body 1 is connected to the drainage limiter module 4.

[0043] The bandaging mechanism 2 includes a position adjustment module 21 and a moving module 22. The position adjustment module 21 is provided in two groups and is respectively installed on the left and right sides of the wearable body 1. Both groups of position adjustment modules 21 are connected to the moving module 22. The position adjustment module 21 is connected to the pressurized fine adjustment component 3.

[0044] The moving module 22 includes a moving component 221 and an adjusting component 222 . The moving component 221 is connected to the position adjusting module 21 on the right side, and the adjusting component 222 is connected to the position adjusting module 21 on the left side.

[0045] When the present invention is used, the medical gauze roll is installed on the mobile component 221. After the installation is completed, the wearable body 1 is worn on the patient, and the position of the mobile component 221 and the adjustment component 222 are adjusted according to the position of the patient's wound through the position adjustment module 21. Then, the patient's wound is coated with medicine and bandaged, and the drainage tube is inserted and fixed on the drainage limiting module 4 to prevent the drainage tube from shifting and detaching from the wound when the patient moves;

[0046] The medical gauze is then pulled out from the moving component 221 and wound around the adjusting component 222. The adjusting component 222 reels the medical gauze. After the medical gauze is fixed, the pressurizing fine-adjusting component 3 is fixed to the outside of the medical gauze to apply pressure to the patient's wound.

[0047] The present invention can reel in and unreel the medical gauze through the moving component 221 and the adjusting component 222, thereby facilitating dressing changes on the patient's wound. When the medicine penetrates into the medical gauze, the medical gauze can be reeled in through the adjusting component 222 and adjusted to a clean section of medical gauze for bandaging.

[0048] The position of the medical gauze of the present invention can be adjusted up and down, and the tightness can be adjusted by the moving component 221 and the adjusting component 222 to adapt to the wound position and dressing change requirements of different patients;

[0049] The pressurization fine-tuning component 3 uses a pressure sensor 38, a display screen 39 and a controller 310 to accurately monitor the pressure, and adjusts the pressure range through the airbag 32 and the micro air pump 33 to meet the pressure requirements of the patient at different recovery stages.

[0050] The wearable body 1 includes a vest 11, a fixing strap 12, a Velcro 13 and a fixing strip 14. The fixing straps 12 are provided with two and are fixedly installed on the left and right sides of the back half of the vest 11 respectively. The Velcro 13 is provided with two and is fixedly installed on the left and right sides of the front half of the vest 11 respectively. The two fixing straps 12 are respectively adhesively connected to the left and right sides of the front half of the vest 11 through the two Velcros 13. The fixing strips 14 are provided with two and are fixedly installed on the front side of the back half of the vest 11 respectively. The fixing strips 14 are connected to the position adjustment module 21, the moving component 221, the adjustment component 222, the pressurization fine adjustment component 3, and the drainage limiting module 4.

[0051] The Velcro 13 is a fleece surface, and the hook surface is fixedly mounted on the fixing strip 14 , and the fleece surface and the hook surface are detachably connected.

[0052] Working principle: Spread out the front and back parts of the vest 11 so that the patient is located on the back half of the vest 11. After bandaging the patient's wound, first use the drainage limiting module 4 to store the drainage tube, then adjust the position adjustment module 21, the moving component 221, and the adjustment component 222, and then flip the front half of the vest 11 to the patient's chest, and then fix the fixing belt 12 and the front half of the vest 11 together with the Velcro 13.

[0053] The position adjustment module 21 includes a slider 212, a limit block 213 and a movable column 214. A first slide groove 211 and a second slide groove 215 are opened inside the fixed bar 14. The first slide groove 211 is located at the upper end of the second slide groove 215. The first slide groove 211 is slidably connected to the slider 212. The rear end of the movable column 214 is fixedly connected to the limit block 213. The limit block 213 is slidably connected to the second slide groove 215. The movable column 214 is threadedly connected to the slider 212.

[0054] Preferably, the limiting block 213 is in the shape of a truncated cone.

[0055] The first slide groove 211, slider 212, limit block 213, movable column 214, and second slide groove 215 are each provided with two and are respectively located in the fixed bar 14 on the left and right sides. The sliders 212 on the left and right sides are respectively connected to the movable component 221 and the adjustment component 222.

[0056] Working principle: When the slider 212 is locked, the limit block 213 contacts the front end of the second slide groove 215, and the slider 212 is fixed under the action of friction;

[0057] When the slider 212 is adjusted in position, the movable column 214 is first rotated, and the movable column 214 drives the limit block 213 to move together. Since the movable column 214 and the slider 212 are threadedly connected, during the rotation of the movable column 214, based on the transmission principle of the thread, the limit block 213 moves backward inside the second slide groove 215, thereby disengaging the limit block 213 from the front end of the second slide groove 215. At this time, the slider 212 can move inside the first slide groove 211 and be adjusted to a suitable position.

[0058] As the slider 212 slides up and down in the first slide groove 211, the moving component 221 and the adjusting component 222 connected to the slider 212 also move synchronously;

[0059] Since there are two first slide grooves 211, sliders 212, limit blocks 213, movable columns 214, and second slide grooves 215, and they are respectively located in the fixed bars 14 on the left and right sides, during operation, the left and right sides can perform the same adjustment action synchronously, ensuring the balance and symmetry of the movable component 221 and the adjustment component 222 during position adjustment, and meeting the actual usage needs of different patients.

[0060] The moving assembly 221 includes a first fixed plate 2211, a rotating shaft 2212, a first ratchet 2213, a first pawl 2214, a first tension spring 2215, a mounting plate 2216 and a bolt 2217. The first fixed plate 2211 is fixedly mounted on the upper end of the slider 212. The upper end of the rotating shaft 2212 is rotatably connected to the first fixed plate 2211. The side wall of the rotating shaft 2212 is fixedly connected to the inner wall of the first ratchet 2213. The first ratchet 2213 is fixedly connected to the first ratchet 2213. One end of a pawl 2214 is unidirectionally meshed and connected, the other end of the first pawl 2214 is rotatably connected to the first fixed plate 2211, one end of the first tension spring 2215 is fixedly connected to the first fixed plate 2211, the other end of the first tension spring 2215 is fixedly connected to the first pawl 2214, one end of the mounting plate 2216 is rotatably connected to the lower end of the rotating shaft 2212, and the other end of the mounting plate 2216 is detachably connected to the lower end of the slider 212 by a bolt 2217.

[0061] The adjusting assembly 222 includes a rotating shaft 2221, a second ratchet 2222, a second pawl 2223, a second tension spring 2224, a rotating buckle 2225 and a second fixing plate 2226, and the second fixing plate 2226 is provided with two and is respectively fixedly installed at the upper and lower ends of the left slider 212. The upper and lower ends of the rotating shaft 2221 are rotatably connected to the two second fixing plates 2226, and the side walls of the rotating shaft 2221 are fixedly connected to the inner wall of the second ratchet 2222, the second ratchet 2222 is unidirectionally meshed with one end of the second pawl 2223, the other end of the second pawl 2223 is rotatably connected to the second fixing plate 2226 at the upper end, one end of the second tension spring 2224 is fixedly connected to the second fixing plate 2226, the other end of the second tension spring 2224 is fixedly connected to the second fixing plate 2223, the rotating buckle 2225 is fixedly connected to the upper end of the rotating shaft 2221, and the rotating buckle 2225 is located above the second fixing plate 2226 at the upper end.

[0062] The teeth on the first ratchet 2213 and the second ratchet 2222 are oriented in the same direction, ensuring that the rotating shaft 2212 and the rotating shaft 2221 can rotate in opposite directions.

[0063] Working principle: The mounting plate 2216 is removed from the lower end of the slider 212 by means of the bolt 2217, and then the medical gauze roll is mounted on the rotating shaft 2212. One end of the medical gauze is pulled out and fixed on the rotating shaft 2221. The rotating buckle 2225 is rotated, so that the rotating buckle 2225 drives the rotating shaft 2221 to rotate, and then the second ratchet 2222 rotates. When the second ratchet 2222 rotates, the second pawl 2223 is acted upon by the second tension spring 2224, so that the second ratchet 2222 can only rotate in one direction, thereby preventing the rotating shaft 2221 from reversing.

[0064] At the same time, the rotation of the rotating shaft 2221 drives the medical gauze to rotate together, and the medical gauze drives the rotating shaft 2212 to rotate. Since the rotating shaft 2212 is fixedly connected to the first ratchet 2213, the first ratchet 2213 will rotate accordingly. Similarly, the first pawl 2214 can only allow the first ratchet 2213 to rotate in one direction under the tension of the first tension spring 2215, so that the rotating shaft 2212 can only rotate in one direction, thereby ensuring the stability of the movement of the rotating shaft 2212;

[0065] Under the action of the first ratchet 2213 and the second ratchet 2222, the rotating shaft 2212 and the rotating shaft 2221 cover the medical gauze above the wound. The first ratchet 2213 and the second ratchet 2222 also facilitate the replacement of wound medicine. It is only necessary to unlock the first ratchet 2213 through the first pawl 2214 to adjust the tightness of the medical gauze. The medical gauze does not need to be removed and the medicine can be directly replaced.

[0066] If the medicine penetrates into the medical gauze, the medical gauze can be rolled up by adjusting the rotating buckle 2225 to adjust it to a clean section of medical gauze.

[0067] By covering and bandaging the wound with medical gauze, not only is it possible to conveniently replace medicines, but also the medical gauze can be used to apply initial pressure to the wound.

[0068] Embodiment 2: In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the pressurized fine adjustment component 3 includes a fixing cloth 31, an air bag 32, a micro air pump 33, an elastic cloth 34, a mounting bag 35, a movable buckle 36, a pressure sensor 38 and a display screen 39. One end of the fixing cloth 31 is fixedly connected to the slider 212 on the right, the other end of the fixing cloth 31 is adhesively connected to one end of the elastic cloth 34, the other end of the elastic cloth 34 is fixedly connected to the slider 212 on the left, the lower end of the elastic cloth 34 is fixedly connected to the mounting bag 35, and the elastic cloth 34 is fixedly connected to the mounting bag 35.

The pressure sensor 38 is fixedly installed on the upper end of the movable buckle 36. The display screen 39 is fixedly installed on the front side of the front half of the vest 11. The display screen 39 is used to display pressure data.

[0069] The pressurized fine adjustment component 3 also includes a controller 310 . The pressure sensor 38 is electrically connected to the controller 310 . The controller 310 is electrically connected to the display screen 39 and the micro air pump 33 . The controller 310 is fixedly mounted on the front side of the front half of the vest 11 .

[0070] The micro air pump 33 is a low-noise, small-volume air pump whose suction flow and pressure can meet the demand for supplementing negative pressure. When the micro air pump 33 receives a start signal from the controller 310, it can start quickly to pressurize the airbag 32.

[0071] Working principle: After the medical gauze is properly fixed above the wound, the elastic cloth 34 is tightly adhered to the fixed cloth 31. At this time, the position of the movable buckle 36 is carefully adjusted so that the movable buckle 36 drives the air bag 32 to move smoothly to the top of the wound;

[0072] Then, the micro air pump 33 is started to slowly increase the pressure in the air bag 32 so that the pressure of the air bag 32 acts on the wound, achieving precise compression of the wound;

[0073] The pressure sensor 38 monitors the pressure data in the airbag 32 in real time and quickly uploads this data to the controller 310. After the controller 310 analyzes and processes the data, it uploads the results to the display screen 39 for clear display. The caregiver can then understand the pressure situation intuitively and promptly, and then accurately adjust the pressure according to actual needs.

[0075] Working principle: When storing the drainage tube, the drainage tube is wound around the rotating rod 41, and the inner pawl 45 is manually opened to disengage the inner ratchet 44 and the inner pawl 45. The knob 46 is rotated, and the knob 46 drives the rotating disk 42 to rotate together. The rotating disk 42 is fixedly connected to the rotating rod 41, so the rotating rod 41 also rotates, and the rotating rod 41 drives the drainage tube to rotate together, and the tail of the drainage tube is pulled out to the storage box 47. The inner pawl 45 is lowered, so that the inner ratchet 44 and the inner pawl 45 are re-engaged, thereby storing the middle part of the drainage tube in the storage box 47. Finally, the tail of the drainage tube is connected to the drainage bag;

[0076] Since the drainage tube is wrapped around the rotating rod 41, when an external force pulls the drainage bag, the inner ratchet 44 and the inner pawl 45 are in a locked state, the drainage tube is fixed and the drainage bag will not pull the drainage tube, thereby avoiding the situation where the drainage tube is separated from the wound due to the force applied to the drainage bag, effectively protecting the patient's wound, reducing the risk of infection, and ensuring the normal drainage work.

[0077] When the patient moves too much, the drainage tube will be pulled to move together, and the drainage tube will drive the rotating rod 41 to move. At this time, under the action of the vortex spring 43, the inner ratchet 44 and the inner pawl 45 are not locked, and the rotating rod 41 will drive the inner pawl 45 to move together, thereby adjusting the length of the drainage tube to prevent the patient from moving too much and pulling off the drainage tube. While ensuring the patient's safety, it gives the patient a certain amount of space to move and improves the patient's comfort.
