Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical auxiliary devices, and particularly relates to a limb suspension pad. Background Art
[0002] In clinical work, it is found that for patients with limb skin flap transfer, since the skin flap at the skin graft site is in an area prone to compression (such as the inner side of the upper arm, the elbow joint, the inner side of the forearm, the back of the thigh, the back of the calf, the popliteal fossa, the calcaneus, and the inner and outer sides of the ankle joint), it is ultimately easy to cause necrosis of the skin flap at the skin graft site. For the existing auxiliary devices for elevating the affected limb, generally there is a single elevation pad. Such an elevation pad is not suitable for all patients, and the positions of limb skin flap transfer are also different. Therefore, the existing elevation pads have poor adaptability, and it is easy for the affected limb or the elevation pad to shift unconsciously when the patient is sleeping, ultimately resulting in ischemia, hypoxia, and necrosis of the skin flap due to compression. Content of the Utility Model
[0003] The utility model provides a limb suspension pad, which solves the problem in the prior art that the skin flap transfer and the elevation pad are in contact and squeezed with each other, resulting in necrosis of the skin flap at the skin flap transfer site.
[0004] The technical solution of the utility model is realized as follows:
[0005] A limb suspension pad includes a first elevation pad and a second elevation pad combined with each other. The first elevation pad is used for placing the patient's calf, and the second elevation pad is used for placing the patient's thigh.
[0006] An arc surface is arranged at the upper end of the first elevation pad. When the calf or forearm is placed, it is suspended along the arc surface so that the affected area is not squeezed by the first elevation pad.
[0007] First and second placement grooves are respectively formed at the upper and lower ends of the second elevation pad. The second placement groove includes a placement groove opened along the direction of the patient's thigh or upper arm, and a ventilation groove perpendicular to the placement groove. When the thigh or upper arm is placed, the ventilation groove is recessed to make the skin flap transfer site of the thigh or upper arm suspended and not squeezed by the second elevation pad.
[0008] As a preferred technical solution of the present application, the depth of the ventilation groove is greater than the depth of the placement groove. When the patient's thigh or upper arm is placed along the placement groove, the ventilation groove does not contact the affected area at the back of the thigh or the inner side of the upper arm.
[0009] As a preferred technical solution of the present application, magic tapes are fixedly arranged on the sides of the first elevation pad and the second elevation pad for mutual adhesion between the two.
[0010] As a preferred technical solution of the present application, a strap member for fixing the patient's limb is further arranged on the second elevation pad.
[0011] As a preferred technical solution of the present application, the strap member includes a strap body. One end of the strap body is fixedly arranged on one end face of the upper side of the second elevation pad, and a buckle is installed at the other end of the second elevation pad for connecting the other end of the strap body. A male surface is arranged on the end face of the strap body near one end of the buckle, and a female surface is correspondingly arranged along another area of the strap body. After the strap body is folded along the buckle, the male surface and the female surface are adhered to each other to fix the patient's leg.
[0012] As a preferred technical solution of the present application, the buckle includes a connecting seat fixedly installed on the upper end of the second elevation pad. A connecting buckle is movably arranged inside the connecting seat, and a long groove is opened inside the connecting buckle to facilitate the passing of the strap body.
[0013] As a preferred technical solution of the present application, the strap body is an elastic band.
[0014] As a preferred technical solution of the present application, connecting columns are further arranged at the central positions of the side walls of the first elevation pad and the second elevation pad, and connecting holes are correspondingly opened at the second elevation pad to facilitate the insertion of the connecting columns along the connecting holes.
[0015] As a preferred technical solution of the present application, the connecting column includes a column body and a blocking ring fixedly sleeved along the outer side of the column body.
[0016] As a preferred technical solution of the present application, the blocking ring is made of rubber material.
[0017] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0018] In the present utility model, by providing the first elevation pad and the second elevation pad, the two elevation pads can be combined with each other to form elevation pads of different lengths to facilitate adaptation to the limb lengths of different patients.
[0019] In the present utility model, by providing the arc surface and the second placement groove, the skin flap transfer area of the limb does not come into contact with the elevation pad, avoiding the situation of extrusion. Description of the Drawings

Specific embodiments
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0030] Embodiment 1: A limb suspension pad includes a mutually combined first elevation pad 10 and a second elevation pad 20. As Figure 1 shown, at the back of the patient's calf or the inner side of the forearm flap transfer area, due to the arc surface 11 on the upper end face of the first elevation pad 10, it can be ensured that there is no contact between the back of the calf or the inner side of the forearm flap transfer area and the first elevation pad 10, avoiding necrosis due to compression, ischemia, and hypoxia;
[0031] While the thigh or upper arm is placed on the second elevation pad 20. Since the elevation pads can be mutually combined to form a new elevation pad assembly, medical staff can freely combine the elevation pads according to the specific flap transfer area of the patient's limb and the length of the patient's limb, solving the problem that the elevation pad is not suitable for the patient because its length cannot be changed;
[0032] The combination of the elevation pads in this application is as follows Figure 3 As shown, there is a Velcro 24 provided on the side of the elevation pad, and the Velcro 24 is used to achieve the fixed connection between the first elevation pad 10 and the second elevation pad 20;
[0033] There is also a first placement groove 21 opened inside the second elevation pad 20 to facilitate the placement of the thigh or upper arm;
[0034] Considering that if the flap transfer site is located at the back of the thigh or the inner side of the upper arm, it is not very suitable to use the first placement groove 21 to place the patient's thigh or upper arm at this time. Therefore, a second placement groove 22 is also opened at the lower end of the second elevation pad 20 to place the flap transfer site at the back of the thigh or the inner side of the upper arm. For this reason, the second elevation pad 20 can be rotated 180 degrees to turn the second placement groove 22 upward for the placement of the patient's thigh or upper arm;
[0035] As Figure 7 shown, the second placement groove 22 includes a placement groove 22B opened along the length direction of the thigh or upper arm, and a ventilation groove 22A perpendicular to the placement groove 22B. The thigh or upper arm is placed along the placement groove 22B, and the flap transfer site is placed along the ventilation groove 22A. The depth of the ventilation groove 22A is greater than the depth of the placement groove 22B. Therefore, the affected area will not come into contact with the main body of the second elevation pad 20 to achieve a suspended effect, thus avoiding the situation of squeezing the affected area;
[0036] Embodiment 2: The difference from Embodiment 1 is that in order to solve the problem that the affected limb may move during the patient's sleep, or the elevation pad itself may shift, a strap member 30 as shown in Figure 5-6 is also provided on the elevation pad. Among them, as shown in Figure 6 the strap member 30 includes a strap main body 301. One end of the strap main body 301 is sewn and connected to the upper end face of the second elevation pad 20, and a buckle member is also bound to the other end. The buckle member includes a connection seat 302 fixedly provided at the other upper end face of the second elevation pad 20. A connection buckle 303 is movably connected inside the connection seat 302. A long groove is opened along the strap main body 301 inside the connection buckle 303 to facilitate the strap main body 301 to pass through the long groove to be connected with the connection buckle 303. A sub-surface 304 is provided on the end face of the strap main body 301 near the connection buckle 303, and a mother surface 305 is correspondingly provided along another area of the strap main body 301 to facilitate the sub-surface 304 to be fixedly adhered to the mother surface 305, so that the thigh can be fixed on the second elevation pad 20;
[0037] Embodiment 3: The difference from Embodiment 1 and Embodiment 2 is that in order to make the upper end of the second elevation pad 20 flush and facilitate rotation, as shown in Figure 2-3 and Figure 5As shown in the figure, connecting columns 40 are provided on the first elevation pad 10 and the second elevation pad 20, and the connected second elevation pad 20 is provided with connection holes 23 for the connecting columns 40 to be inserted therein. To facilitate the rotation of the second elevation pad 20, as Figure 4 shown, the connecting column 40 further includes a column body 401, and a blocking ring 402 is fixedly sleeved on the outer side of the column body 401. When inserted into the connection hole 23, due to the blocking of the blocking ring 402, the magic tapes 24 on the side of the second elevation pad 20 will not contact each other, facilitating the rotation of the second elevation pad 20. Then, rotate along the center of the column body 401 to turn the second placement groove 22 upwards. Then, forcefully squeeze the column body 401 into the connection hole 23 again, so that the magic tapes 24 on the side contact each other and are fixedly adhered together, which can ensure that the upper end surface of the second elevation pad 20 is flush and convenient for placing the thigh or upper arm.
[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
