Technical Field

[0001] The present application relates to the field of medical protective gear, and in particular to an anti-pressure sore pad. Background Art

[0002] Pressure ulcers, also known as bedsores, are caused by long-term pressure on local tissue, resulting in persistent ischemia, hypoxia, and malnutrition leading to tissue necrosis. Patients who are bedridden for a long time or have limited mobility and need to sit in a wheelchair for a long time are prone to pressure ulcers in the sacrum and buttocks.

[0003] At present, pressure sore pads are often used to protect patients with pressure sores on the sacrum and buttocks or patients who have undergone hemorrhoid surgery. However, due to the different sizes of patients' buttocks and the different locations of sores, multiple pressure sore pads of different sizes and specifications are needed for doctors to choose from.

[0004] However, since each specification of the anti-pressure sore pad can be adapted to a certain size of buttocks and the area for avoiding the sore site is fixed, there is still a situation where it is difficult to fit the anti-pressure sore pad to the patient's buttocks. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the related art, the present application provides an anti-pressure sore pad.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The present application embodiment discloses an anti-pressure sore pad. Figure 1 , an anti-pressure sore pad includes two seat cushions 1 for supporting the buttocks of the user on both sides, the seat cushions 1 are arranged in an arc shape along the width direction thereof, and when in use, the inner arc surface faces the buttocks of the user, and the two seat cushions 1 are connected by an elastic band 2, and two elastic bands 2 are provided, and the two elastic bands 2 are respectively arranged at the two ends of the seat cushion 1 along the length direction thereof; a side where the two seat cushions 1 are close to each other is provided with an avoidance structure 3 for the user to avoid the sore part when in use, and the avoidance structure 3 is arranged on the side of the seat cushion 1 close to the other seat cushion 1, and is located between the connection positions of the two elastic bands 2. In the embodiment of the present application, the avoidance structure 3 is arranged along the length direction of the seat cushion 1 as an arc-shaped protrusion formed relative to the inner arc surface of the seat cushion 1, and the side where the avoidance structures 3 respectively located on the two seat cushions 1 are close to each other are all inner arc surfaces, and when in use, the gap between the two avoidance structures 3 can not only avoid the sore part, but also support the non-sore part to prevent the sore part from touching the seat under the anti-pressure sore pad. In other embodiments, the avoidance structure 3 may also be configured as a avoidance hole opened on the seat cushion 1 , or a recessed structure provided on the inner arc surface of the seat cushion 1 .

[0031] When the user uses the anti-pressure sore pad, the seat cushion 1 is placed on the seat with the inner arc surface facing upwards, and the elastic band 2 is stretched so that the two seat cushions 1 are respectively against the buttocks of the user on both sides. When the user sits down, the avoidance structure 3 supports the buttocks of the user so that the buttocks are spread apart, thereby preventing the pressure sores from being squeezed by the buttocks and other objects.

[0032] Reference Figure 2, both ends of the elastic band 2 are provided with connecting blocks 5, and the connecting blocks 5 are detachably connected to the seat cushion 1. Figure 3 and Figure 4 The seat cushion 1 is provided with an embedding groove 7 for accommodating the connecting block 5, and positioning grooves 11 are provided on the two inner side walls opposite to each other in the width direction of the embedding groove 7, and slide grooves 16 are provided on the two opposite side walls in the length direction of the connecting block 5. A positioning pin 12 is provided in the slide groove 16 to slide along the length direction of the connecting block 5, and the positioning pin 12 is plugged and adapted with the positioning groove 11. In order to prevent the positioning pin 12 from falling out of the slide groove 16 as much as possible, the slide groove 16 is stepped along the length direction of the connecting block 5, and the positioning pin 12 is also stepped along its length direction, and the diameter of one end close to the inner bottom wall of the slide groove 16 is larger than the diameter of the other end. A sliding hole 17 connected to the sliding groove 16 is provided on the side of the connecting block 5 away from the bottom wall of the embedding groove 7. The opening of the sliding hole 17 is rectangular and its length direction is arranged along the length direction of the connecting block 5. A toggle plate 13 is slidably arranged in the sliding hole 17 along the sliding direction of the positioning pin 12. One end of the toggle plate 13 is fixed to the positioning pin 12, and the other end extends to the opening of the sliding hole 17 away from the sliding groove 16.

[0033] When the connecting block 5 needs to be removed from the seat cushion 1, the two toggle plates 13 are driven to move toward each other, thereby driving the positioning pin 12 to disengage from the positioning groove 11, completing the unlocking of the connecting block 5 on the seat cushion 1, and the connecting block 5 and the elastic band 2 can be removed together for easy replacement.

[0034] In order to improve the stability of the connecting block 5 when it is installed on the seat cushion 1, refer to Figure 4 , an elastic member 14 is provided in the slide slot 16 for driving the positioning pin 12 to move in a direction away from the inner bottom wall of the slide slot 16. In the embodiment of the present application, the elastic member 14 is configured as a spring, one end of the spring abuts against the inner bottom wall of the slide slot 16, and the other end abuts against the end of the positioning pin 12. When the connecting block 5 is fixed to the seat cushion 1, the positioning pin 12 is driven to abut against the inner bottom wall of the positioning slot 11 under the action of the spring force. In other embodiments, the elastic member 14 can also be configured as an elastic telescopic cylinder or a spring leaf.

[0035] In order to facilitate the removal of the loose or damaged elastic band 2 from the connecting block 5 and replace it, refer to Figure 4 , the two connecting blocks 5 are provided with insertion grooves 8 on the sides close to each other, and the connecting blocks 5 are threadedly connected with bolts 15, and the end of the screw of the bolt 15 extends into the insertion groove 8, and one end of the elastic band 2 is fixed in the insertion groove 8 by the bolt 15. In the embodiment of the present application, the end of the screw of the bolt 15 presses one end of the elastic band 2 against the inner wall of the insertion groove 8, thereby completing the detachable fixation of the elastic band 2. In other embodiments, a clearance hole is provided at the end of the elastic band 2, and the bolt 15 passes through the clearance hole and abuts against the inner wall of the insertion groove 8, which can also achieve the detachable fixation of the elastic band 2 and the connecting block 5.

[0036] When using an anti-pressure sore pad, the user's legs are lifted because the buttocks are supported, which can easily cause discomfort. Figure 1 and Figure 5 A leg support plate 6 is provided at one end of the seat cushion 1, and the leg support plate 6 is arranged in an arc shape along the width direction thereof, and the leg support plates 6 on the two seat cushions 1 are also connected by an elastic band 2. In order to further improve the comfort of the user's legs, the thickness of the leg support plate 6 gradually decreases from one end of the leg support plate 6 close to the seat cushion 1 to the other end, so as to avoid indentations on the user's legs as much as possible. The surfaces of the seat cushion 1 and the leg support plate 6 that are used to contact the user are both provided with a sponge layer 4, so as to further improve the comfort of the user.

[0037] Reference Figure 3 and Figure 5 , the leg support plate 6 is slidably connected with the seat cushion 1. Specifically, a first arc slide 9 is provided on the end surface of the seat cushion 1 near the leg support plate 6, and a second arc slide 18 is provided on the end surface of the leg support plate 6 near the seat cushion 1. The first arc slide 9 and the second arc slide 18 are both stepped along their depth direction. The first arc slide 9 and the second arc slide 18 are connected by an I-shaped slider 10. The slider 10 is cylindrical, and the two ends of the slider 10 are respectively embedded in the first arc slide 9 and the second arc slide 18. The leg support plate 6 is rotated and slid on the seat cushion 1 through the slider 10, so that when the user's legs rotate, the leg support plate 6 rotates relative to the seat cushion 1, and the leg support plate 6 is prevented from moving the seat cushion 1 when the leg support plate 6 and the seat cushion 1 are fixed, which causes the sore part to be squeezed.

[0038] The implementation principle of an anti-pressure sore pad in the embodiment of the present application is as follows: when the user uses the anti-pressure sore pad, the seat cushion 1 is placed on the seat with the inner arc surface facing upwards, and the elastic band 2 is stretched so that the two seat cushions 1 are respectively against the buttocks of the user on both sides. When the user sits down, the avoidance structure 3 supports the buttocks of the user so that the buttocks are spread apart, so that the pressure sores are not squeezed by the buttocks and other objects. When the elastic band 2 is damaged or the elastic force is insufficient, the two toggle plates 13 are driven to move in a direction close to each other, thereby completing the disassembly of the connecting block 5 on the seat cushion 1 / leg support plate 6, and then the bolts 15 are loosened, and the elastic band 2 is taken out from the connecting block 5 for replacement.
