Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a protective pad for injured limbs. Background Art

[0002] In the care of fractures of injured limbs, the existing fixed splints can keep the injured limb in a fixed position, but maintaining a functional position for a long time is inconvenient for the patient to move and recover, and it will cause secondary injuries when the patient accidentally falls or bumps into something. Small air pillows are beneficial for blood return to reduce swelling and relieve pain, but they cannot maintain a fixed position because the shape of the air pillow changes easily after being compressed. Forearm sling care is beneficial for maintaining the functional position of the fractured upper limb, preventing limb swelling, avoiding pain and discomfort, and preventing complications such as forearm slippage and local skin ulcers. However, because the forearm sling limits joint movement and the joint is kept in a fixed position, it will cause joint soreness symptoms and even joint stiffness. Therefore, traditional care for fractures of injured limbs will more or less cause discomfort to patients and fail to achieve satisfactory treatment results for patients. Utility Model Content

[0003] The utility model aims to provide a protective pad for an injured limb, so as to alleviate the discomfort brought to patients by the existing fracture care.

[0004] According to the first aspect of the present invention, a protective pad for an injured limb comprises:

[0014] According to some embodiments of the present utility model, in order to adapt to the shape of the limbs, the upper surface of the front base and the upper surface of the rear base are both arc-shaped concave surfaces.

[0015] According to some embodiments of the utility model, a first adhesive tape is fixedly provided on the upper surface of the front base, and a second adhesive tape detachably connected to the first adhesive tape is fixedly provided on the front air cushion. The above arrangement can conveniently replace the front air cushion, thereby meeting the needs of different user groups.

[0016] According to some embodiments of the utility model, a third adhesive tape is fixedly provided on the upper surface of the rear base, and a fourth adhesive tape detachably connected to the third adhesive tape is fixedly provided on the rear air cushion. The above arrangement can conveniently replace the rear air cushion, thereby meeting the needs of different user groups.

[0017] According to some embodiments of the utility model, since the front base can be used alone, the air pump is installed inside the front base, and a control switch electrically connected to the air pump is provided on the surface of the front base to facilitate inflation and deflation.

[0018] According to some embodiments of the utility model, although the front base and the rear base are connected by the connecting hinge, in some application scenarios, the rear base can be detached from the front base and placed on top of the rear base. At this time, the lower bottom surface of the front base is connected to the lower bottom surface of the rear base, and the upper top surface of the rear base serves as the lower bottom surface of the entire combination. Therefore, in order to meet the requirement of stable placement, the front base and the rear base are both provided with a horizontal lower bottom surface, and the upper surface of the rear base is provided with an enclosure higher than the rear air cushion, and the enclosure has a horizontal top surface.

[0030] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of the first, second, third, and fourth, it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] like Figures 1 to 3As shown, a limb protection pad according to the first aspect of the embodiment of the utility model comprises a front base 100, a rear base 200 and a connecting hinge 300, wherein the front base 100 is located in front of the rear base 200, and the front base 100 and the rear base 200 are connected via the connecting hinge 300. Specifically, the upper surface of the front base 100 is designed as an arc-shaped concave surface according to the shape of the limb, and the upper surface of the front base 100 is connected to a front air cushion 110, and the front air cushion 110 is inflated and deflated by an air pump 400. Since the front base 100 can be used independently, the air pump 400 is optionally installed inside the front base 100, and a control switch 410 for controlling inflation and deflation is provided on the surface of the front base 100.

[0033] Although the front air cushion 110 has a specific shape when inflated, considering the physiological differences of different user groups, in order to adapt to different user groups, the front air cushion 110 needs to be detachably connected to the front base 100 so as to replace different front air cushions 110. To this end, two or more first adhesive tapes 120 are fixedly provided on the upper surface of the front base 100, and the front air cushion 110 is fixedly provided with a second adhesive tape (not shown in the drawings) detachably connected to the first adhesive tape 120. In this embodiment, both the first adhesive tape 120 and the second adhesive tape are selected as Velcro, and the setting positions of the two correspond to each other, so that the front air cushion 110 can be detachably connected to the front base 100.

[0034] In addition, a plurality of front elastic bands 130 are provided in the length direction of the front base 100. In this embodiment, the number of the front elastic bands 130 can be selected to be two, and the two front elastic bands 130 are respectively connected to the front and rear of the front base 100. It can be understood that the front elastic bands 130 are prior art and have a certain elasticity. When the patient places the injured limb on the front air cushion 110, the medical staff can use the front elastic bands 130 to restrain the patient's injured limb, thereby temporarily fixing the injured limb on the front base 100, so as to provide all-round protection for the injured limb, thereby reducing the risk of collision.

[0035] Similarly, the upper surface of the rear base 200 is designed as an arc-shaped concave surface according to the shape of the limbs. The upper surface of the rear base 200 is connected to the rear air cushion 210. In order to save costs, the rear air cushion 210 is also inflated and deflated by the air pump 400 disposed in the front base 100. The air pump 400 is provided with two gas branches (not shown in the drawings) respectively connected to the front air cushion 110 and the rear air cushion 210. The two gas branches are connected to the gas main road of the air pump 400 through a reversing valve (not shown in the drawings) to achieve independent control of the front air cushion 110 and the rear air cushion 210. However, the utility model does not limit the number of the air pumps 400. In some other embodiments, an air pump 400 can be disposed inside the front base 100 and the rear base 200 to form a double pump, which is not limited to the above embodiments.

[0036] Although the rear air cushion 210 has a specific shape when inflated, considering the physiological differences of different user groups, in order to adapt to different user groups, the rear air cushion 210 needs to be detachably connected to the rear base 200 so as to replace different rear air cushions 210. To this end, two or more third adhesive tapes 220 are fixedly provided on the upper surface of the rear base 200, and the rear air cushion 210 is fixedly provided with a fourth adhesive tape (not shown in the drawings) detachably connected to the third adhesive tape 220. In this embodiment, the third adhesive tape 220 and the fourth adhesive tape are both selected as Velcro, and the setting positions of the two correspond to each other, so that the rear air cushion 210 can be detachably connected to the rear base 200.

[0037] In addition, a plurality of rear elastic bands 230 are provided in the length direction of the rear base 200. In this embodiment, the number of the rear elastic bands 230 can be selected to be two, and the two rear elastic bands 230 are respectively connected to the front and rear of the rear base 200. It can be understood that the rear elastic band 230 is a prior art, which has a certain elasticity. When the patient places the injured limb on the rear air cushion 210, the medical staff can use the rear elastic band 230 to restrain the patient's injured limb, thereby temporarily fixing the injured limb on the rear base 200, so as to provide all-round protection for the injured limb, thereby reducing the risk of collision.

[0038] On the other hand, one of the front end and the rear end of the connecting hinge seat 300 is provided with a rotating slider 310, and the other is provided with a rotating frame 320. Correspondingly, one of the front base 100 and the rear base 200 is provided with an arc-shaped slide groove 140 matching the rotating slider 310, and the other is hinged to the rotating frame 320 in the up-down direction. Through the above arrangement, the front base 100 and the rear base 200 have two degrees of rotational freedom, which can respectively cope with the swinging motion and the twisting motion of the patient, such as Figure 4 As shown, this is a schematic diagram of the utility model in response to the patient's twisting movement.

[0039] In this embodiment, the arc-shaped slide groove 140 is provided on the front base 100, and at the same time, the rear base 200 is provided with a notch 240 matching the rotating frame 320, and the rotating frame 320 and the notch 240 are connected by a pin 500. In order to limit the degree of freedom of the front base 100 and the rear base 200 in the front-back direction, the vertical sections of the arc-shaped slide groove 140 and the rotating slider 310 are both T-shaped structures, and the first and second ends of the arc-shaped slide groove 140 are provided with an upwardly open tongue 141, and the rotating slider 310 enters the arc-shaped slide groove 140 from any one of the tongues 141. Under the limitation of the T-shaped groove, the rotating slider 310 can only slide along the extension direction of the arc-shaped slide groove 140, and cannot be separated from the arc-shaped slide groove 140. It can be understood that the arc-shaped slide groove 140 only needs to be provided with an upwardly open tongue 141 at any one end thereof, and is not limited to the above embodiment.

[0040] Furthermore, in order to prevent the rotating slider 310 from sliding out of the groove 141 to the outside of the arc-shaped slide groove 140, the arc-shaped slide groove 140 is detachably connected with a limiting plate 142 at its groove 141, so as to limit the moving path of the rotating slider 310. In order to prevent the limiting plate 142 from protruding out of the front base 100, the front base 100 is provided with an escape position 150 that avoids the limiting plate 142. During assembly, the limiting plate 142 is first removed, and then the rotating slider 310 of the connecting hinge seat 300 is inserted into the arc-shaped slide groove 140 from the groove 141, and finally the limiting plate 142 is installed back to the position covering the groove 141. Through the above-mentioned arrangement, no matter how the patient twists his injured limb, the connecting hinge seat 300 will not be separated from the front base 100, which can avoid safety accidents on the one hand and prevent the patient from being injured due to excessive twisting on the other hand.

[0041] It should be noted that the present invention does not limit the connection relationship between the connecting hinge 300 and the front base 100 and the rear base 200. In other embodiments, the arc-shaped slide groove 140 can also be arranged on the rear base 200, and the front base 100 and the rotating frame 320 of the connecting hinge 300 are hinged in the up and down directions, without being limited to the above embodiments.

[0042] In some embodiments of the utility model, in order to cope with some application scenarios, the injured limb protective pad further includes a sling 600, the sling 600 is provided with a plurality of overhead ends 610, and the front base 100 and the rear base 200 are both provided with a plurality of connecting buckles (not shown in the drawings) for connecting the overhead ends 610, so as to achieve the installation of the sling 600. Since the sling 600 is detachably connected to the connecting buckle, the sling 600 can be connected to the front base 100 and the rear base 200 at the same time, and can also be connected to the front base 100 or the rear base 200 separately, so as to meet different application scenarios.

[0043] With the above structure, when the patient is lying in bed, the injured limb can be placed on the injured limb pad and tied with an elastic band, and then the air pump 400 is started to inflate the air cushion under the injured limb and expand it to a preset shape, which is conducive to blood reflux to achieve the effect of reducing swelling and relieving pain. In addition, since there are two rotational degrees of freedom between the front base 100 and the rear base 200, the patient can swing the joint up and down or twist the joint circumferentially under the protection of the injured limb pad to relieve the discomfort of the joint part, and can effectively promote blood circulation and help the patient's recovery. When the patient leaves the bed, if the patient's injured limb is an upper limb, the sling 600 can be worn to maintain the functional position of the upper limb. During this period, the patient can still relieve discomfort by moving the joint. Compared with the prior art, the utility model integrates the advantages of multiple protective gear and humanely provides patients with multiple degrees of freedom of movement to facilitate patients to carry out daily activities and rehabilitation training.

[0044] like Figure 5 As shown, this is the second embodiment of the utility model. Although the front base 100 and the rear base 200 are connected by the connecting hinge 300, in some application scenarios, the rear base 200 can be detached from the front base 100 and placed on the top of the rear base 200. At this time, the lower bottom surface of the front base 100 is connected to the lower bottom surface of the rear base 200, and the upper top surface of the rear base 200 serves as the lower bottom surface of the entire combination to achieve the effect of raising the front base 100. This embodiment is suitable for patients with fractures of both the upper arm and forearm, or patients with more serious fractures of a single upper arm or forearm. In order to meet the requirements of stable placement, the front base 100 and the rear base 200 are both provided with a horizontal lower bottom surface, and the upper surface of the rear base 200 is provided with a baffle 250 higher than the rear air cushion 210, and the baffle 250 has a horizontal top surface.

[0045] In addition, the front base 100 and the rear base 200 are respectively provided with a first connection portion 160 and a second connection portion 260 that match each other. When the rear base 200 is detached from the front base 100, the front base 100 and the rear base 200 can be assembled up and down through the cooperation of the first connection portion 160 and the second connection portion 260. When the rear base 200 is detached from the connecting hinge seat 300, its pin 500 is also removed together. In order to avoid the loss of parts, the first connection portion 160 and the second connection portion 260 can be selected as connection holes. At this time, the pin 500 can be reused to achieve the connection between the first connection portion 160 and the second connection portion 260.

[0046] Correspondingly, since the rear base 200 is connected to the bottom of the front base 100 , the overhead end 610 of the sling 600 only needs to be connected to the connecting buckle of the front base 100 , and the air pump 400 also disconnects the inflation and deflation of the rear air cushion 210 .

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
