Description

Technical Field

[0001] This invention relates to the field of dressing rack technology, specifically to a dressing rack. Background Technology

[0002] A dressing stand is a support structure used after surgery to hold the injured area where dressings need to be changed, making it easier for caregivers to change the dressings. It is usually used on the patient's limbs.

[0003] When using a dressing stand to support a patient's affected limb, it should primarily support the uninjured limb, leaving the wound suspended in the air. This makes it easier for caregivers to remove dressings, gauze, and infected tissue from the wound and replace the corresponding dressings and gauze. When a patient has a severe leg fracture and is undergoing surgery, the patient's leg needs to be elevated to 20-30 cm above the level of the heart.

[0004] However, during the dressing change process, the patient's affected limb needs to be raised onto the dressing stand. When the patient moves the affected limb, it may pull on the wound, causing the patient to feel more pain and making it inconvenient to change the dressing. Secondly, if the patient's leg is in a raised position for a long time, pressure sores are likely to form on the skin surface, and the leg muscles are likely to atrophy, which will affect the patient's treatment. Therefore, we propose a dressing stand. Summary of the Invention

[0016] Preferably, one side of the support member is provided with an observation mechanism for reflecting the wound on the patient's leg. The observation mechanism includes a plane mirror installed on one side of the support plate. A support rod is fixedly connected to the bottom of the plane mirror. The bottom of the support rod is connected to the support member 2 through a transmission mechanism.

[0017] Preferably, the transmission mechanism includes a rotating shaft rotatably connected to the support plate 1, the rotating shaft and the support plate 1 are connected by a torsion spring, a fixed pulley 1 and a fixed pulley 2 are rotatably connected to one side of the base 1, a transmission groove is opened on one side of the base 1, a transmission rod is slidably connected in the transmission groove, one end of the transmission rod abuts against one side of the support rod, and a pull rope is fixedly connected to one side of the base 2, the pull rope passes through the fixed pulley 2 and the fixed pulley 1 in sequence and is fixedly connected to the transmission rod.

[0039] 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.

[0040] Please see Figure 1-16 The present invention provides a technical solution:

[0041] Example 1,

[0042] A dressing change rack, comprising:

[0043] Mounting bracket 1 is installed on the steel pipe at the foot of the bed, and the device can be easily installed at the foot of the bed through mounting bracket 1;

[0044] Support component 2 is installed on the mounting bracket 1 and supports the patient's distal limb.

[0045] Support component 2 3 is installed on the mounting frame 1 and is located at the proximal end of the patient's heart. Support component 1 2 and support component 2 3 support the affected limbs on both sides of the patient's wound. The dressing area formed between support component 1 2 and support component 2 3 allows medical staff to easily change the dressings of the affected limbs without moving them, reducing the pain of moving the affected limbs and making it convenient for medical staff and patients to use.

[0046] Massage mechanism 4 is installed between support member 1 2 and support member 2 3. When the patient's leg is supported for a long time, massage mechanism 4 massages the patient's leg muscles and changes the position of the supporting skin on the patient's leg. Massage mechanism 4 can facilitate the massage of the affected limb and change the support position of the affected limb, thereby reducing the possibility of pressure sores and ulcers on the surface of the affected limb, facilitating the massage of the patient's muscles and facilitating the patient's later rehabilitation.

[0047] Mounting frame 1 includes a connecting plate 10 connected to the foot of the bed. Two extrusion plates 11 are slidably connected to one side of the connecting plate 10. The two extrusion plates 11 are threaded to the connecting plates 10 on both sides by screws 12. The two screws 12 are rotatably connected to the corresponding extrusion plates 11. A square steel column 13 is fixedly connected to one side of the connecting plate 10. A square steel pipe 14 is slidably connected to the outside of the square steel column 13. A screw 2 15 is threaded to one side of the square steel pipe 14. The screw 2 15 locks the square steel pipe 14 and the square steel column 13. Support 1 2 and support 2 3 are both connected to the square steel pipe 14.

[0048] When the dressing rack needs to be installed at the foot of the bed, the two compression plates 11 inside the connecting plate 10 are inserted into the surface of the steel pipe at the foot of the bed. The screws 12 on both sides are rotated, and the screws 12 push the compression plates 11 to press against the surface of the steel pipe, thereby fixing the square steel column 13 to the steel pipe at the foot of the bed. Then, according to the length of the patient's foot and the location of the patient's wound, the two screws 25 are loosened, and the square steel pipe 14 is pulled. The square steel pipe 14 pulls the support member 12 and support member 23 at its top to the vicinity of the patient's wound. Then the two screws 25 are tightened, and the two screws 215 lock the square steel column 13 and the square steel pipe 14. The mounting frame 1 can then be adjusted to a suitable position to support the patient's wound, which is convenient for supporting the patient's affected limb.

[0049] The support component 2 includes a base 21 that is slidably connected to the square steel tube 14. The base 21 is locked to the square steel tube 14 by a screw 3 22. A support plate 23 is fixedly connected to the top of the base 21, and the support plate 23 supports the affected limb.

[0050] Support component 2 3 includes a base 2 31 that is slidably connected to the square steel tube 14. The base 2 31 is locked to the square steel tube 14 by a screw 4 32. A support plate 2 33 is rotatably connected to the top of the base 2 31. The support plate 2 33 is locked to the surface of the base 2 31 by a screw 5 34.

[0051] Before using support plates 1 (23) and 2 (33) to support the patient's affected limb, loosen screws 3 (22) and 4 (32), and slide bases 1 (21) and 2 (31) on the square steel tube 14 until the skin on both sides of the patient's wound is positioned on top of support plates 1 (23) and 2 (33). Then tighten screws 3 (22) and 4 (32), allowing the patient's affected limb to be placed on top of support plates 1 (23) and 2 (33). This creates a dressing change area between support plates 1 (23) and 2 (33) that facilitates wound care and dressing changes for nursing staff. Secondly, it can also support the patient's affected limb, reduce the possibility of edema at the wound site, and facilitate the return of tissue fluid to the patient's heart. When the patient's leg is bent or the wound is located at the knee, screw 5 34 can be delivered. After screw 5 34 is released, the support plate 2 33 and base 2 31 are rotated relative to each other, and then adjusted to a suitable position for supporting the patient's thigh and lower leg. The patient's affected limb is then placed on top of support plate 1 23 and support plate 2 33, which facilitates the lifting of the affected limb.

[0052] The massage mechanism 4 includes a motor 41 fixedly connected to one side of a square steel tube 14. A rotating rod 5 is provided above the square steel tube 14. A reducer 42 is connected to one end of the rotating rod 5. The reducer 42 is fixedly connected to the square steel tube 14. One side of the reducer 42 is connected to the free end of the output shaft of the motor 41. Multiple cams 43 are fixedly connected to the outside of the rotating rod 5 in an alternating pattern. Each cam 43 has a lifting plate 44 on its top. The multiple lifting plates 44 are slidably connected to the support plate 23 and the support plate 33, respectively.

[0053] After the affected limb is lifted, the motor 41 starts, and the power of the motor 41 is transmitted to the reducer 42. The reducer 42 drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the cam 43 to rotate. The cam 43 will continuously squeeze the lifting plate 44, so that the lifting plate 44 has a massaging effect on the patient's leg. At the same time, the lifting plate 44 continuously changes the contact position with the patient's skin, thereby reducing the possibility of pressure sores on the patient's leg. At the same time, the rotation amplitude is small and the pushing position is located on the patient's normal skin, so it is not easy to cause strain on the patient's surgical site.

[0054] The rotating rod 5 includes a rotating part 51 located below the support plate 23. The bottom of the support plate 33 is rotatably connected to the rotating part 53 via a rotating seat 52. The opposite surfaces of the rotating part 51 and the rotating part 53 are provided with long grooves. The rotating part 51 and the rotating part 53 are connected by a universal joint 54. The two ends of the universal joint 54 are slidably connected to two square grooves 55 in sequence.

[0055] When the patient's injury is located at or near the knee, support plate 23 supports the patient's lower leg, and support plate 33 supports the patient's thigh. When support plate 33 rotates relative to base 31, it pulls rotating part 53 to slide relative to universal joint 54, causing universal joint 54 to rotate. Consequently, when rotating part 51 rotates, it drives rotating part 53 to rotate through universal joint 54. At the same time, the thigh can be massaged while being supported. While rotating support plate 33, rotating part 51, rotating part 53, and universal joint 54 automatically switch angles. The operation is relatively simple, which facilitates massage of the affected limb and reduces the possibility of pressure sores.

[0056] According to the above embodiments, Embodiment Two

[0057] One side of the support member 2 is provided with an observation mechanism 6 that reflects the wound on the patient's leg. The observation mechanism 6 includes a plane mirror 61 installed on one side of the support plate 23. The bottom of the plane mirror 61 is fixedly connected to a support rod 62. The bottom of the support rod 62 is connected to the support member 3 through a transmission mechanism 7.

[0058] The transmission mechanism 7 includes a rotating shaft 71 rotatably connected to the support plate 23. The rotating shaft 71 is connected to the support plate 23 by a torsion spring 72. A fixed pulley 73 and a fixed pulley 74 are rotatably connected to one side of the base 21. A transmission groove 74 is opened on one side of the base 21. A transmission rod 76 is slidably connected in the transmission groove 74. One end of the transmission rod 76 abuts against one side of the support rod 62. A pull rope 77 is fixedly connected to one side of the base 2 31. The pull rope 77 passes through the fixed pulley 74 and the fixed pulley 73 in sequence and is fixedly connected to the transmission rod 76.

[0059] A push plate 78 is slidably connected to one side of the base 21. The push plate 78 contacts the support rod 62. The support rod 62 swings inside the rotating shaft 71. The rotation of the cam 43 will push the push plate 78 to continuously push the support rod 62 to swing, which will facilitate the swing of the plane mirror 61. The periodic swing can facilitate the patient to observe their affected limb from all angles, making it more convenient for the patient to use.

[0060] When the nurse adjusts the length between tray 1 23 and tray 2 33, the base 2 31 pulls the pull rope 77 to move. The pull rope 77 will drive the transmission rod 76 to rise through the fixed pulley 1 73 and fixed pulley 2 74. When the transmission rod 76 rises, it will push the support rod 62 to rotate, which in turn drives the plane mirror 61 to rotate. Thus, the reflection angle of the plane mirror 61 is always aimed at the patient's wound. Therefore, even when the patient is unable to get up, the patient can observe whether there is any seepage or other issues at their wound in real time. This makes it convenient for the patient to notify the nurse in time. The medical staff only need to place the wound between tray 1 23 and tray 2 33. The operation is relatively simple and convenient for the patient to observe themselves.

[0061] According to the above embodiments, in Embodiment 3,

[0062] The support rod 62 is slidably connected to the rotating shaft 71. A track 63 is slidably connected to one side of the base 21. The track 63 contacts the bottom of the support rod 62. A guide post 64 is fixedly connected to one side of the track 63. A guide sleeve 65 is slidably connected to the outside of the guide post 64. A guide seat 67 is rotatably connected to the bottom of the guide sleeve 65. The guide seat 67 is connected to the square steel tube 14 through a moving groove 67. One end of the guide sleeve 65 is connected to the base 31 through a deflection groove 68. A protrusion 69 is provided at the bottom of the support plate 33. The protrusion 69 contacts the guide sleeve 65.

[0063] When observing the wound near the knee while the patient is lying down, it is necessary to rotate the second support plate 33. When the second support plate 33 rotates, it will drive the protrusion 69 to rotate, which will directly push the guide sleeve 65 to rotate. The guide sleeve 65 rotates under the action of the guide seat 67, which in turn drives the guide post 64 on the other side to rotate, which in turn drives the track 63 to rise. When the track 63 rises, it will push the support rod 62 to rise, which makes it easier to raise the plane mirror 61 above the knee, making it easier for the patient to observe their wound. Secondly, when the second support plate 33 is away from the first support plate 23, the lever arm on the side of the guide post 64 increases, and the height of the plane mirror 61 increases, making it easier for the patient to observe themselves.

[0064] Secondly, when the patient has just finished surgery and the anesthesia has not completely worn off, the patient cannot feel if the drainage tube is blocked or if there is leakage from the affected limb. At this time, the plane mirror 61 can better observe the actual situation of the patient's wound, making it easier for the patient to press the call button in time to seek help from medical staff.
