Technical Field

[0001] The invention belongs to the technical field of turning-over pillows, in particular to a turning-over pillow with pressure sensing. Background Art

[0002] The turning pillow is a care product designed specifically for patients who need to turn over regularly. Through its supporting function, the turning pillow can promote the material exchange between tissue cells and interstitial fluid in the compressed parts of the body, reduce the pressure and friction of the compressed tissues, thereby promoting blood circulation and preventing pressure sores.

[0003] In the prior art, if the turning time cannot be adjusted according to the difference in patient weight, especially between heavier patients and lighter patients, there is a significant difference in the force their bodies withstand when under pressure. If a fixed turning time continues to be used, the compressed parts of the body of heavier patients may face more severe compression, thereby increasing the risk of pressure sores.

[0004] To this end, the present invention provides a turning-over pillow with pressure sensing. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1: Figures 1 to 8 As shown, a pressure-sensitive turning pillow described in an embodiment of the present invention includes a triangular pillow 3, an outer wall of the triangular pillow 3 is fixedly installed with an elastic support plate 2, the elastic support plate 2 is arranged in a V-shape, and the opening is downward, the triangular pillow 3 is arranged below the elastic support plate 2, and the triangular pillow 3 is placed on the bed. At this time, the two ends of the elastic support plate 2 will be supported on the bed, and the triangular pillow 3 can be supported to a certain extent.

[0033] The side wall of the elastic support plate 2 is fixedly mounted with a cushion 4, so that the patient's back can lean against the cushion 4 and the patient can assume a side-lying posture, which can facilitate the patient with limited mobility to turn over and also prevent the patient's buttocks from being compressed.

[0034] A pressure sensor 11 is provided inside the triangular pillow 3 for measuring the pressure given by the patient's own weight;

[0035] Since different patients have different weights, the damage to the body caused by lying in bed for a long time is also different. The pressure sensor 11 arranged inside the triangular pillow 3 can monitor the patient's body weight in real time and perform data calculations. The ratio of pressure and time can be measured, so as to calculate the frequency of turning over of the patient of the current weight, thereby improving the patient's comfort while ensuring the rehabilitation effect.

[0036] An execution module is provided inside the triangular pillow 3 for performing data analysis based on the detected pressure;

[0037] The execution module includes a logic controller and a buzzer. The logic controller controls the buzzer to sound intermittently by receiving pressure values, so as to remind medical staff to turn the patient over in time.

[0038] A pillowcase 1 is detachably mounted on the elastic support plate 2. The pillowcase 1 can be mounted on the outside of the elastic support plate 2 by means of common Velcro, and the entire triangular pillow 3 can be wrapped. The easily removable pillowcase 1 is also easy to clean, thereby preventing cross infection among patients.

[0039] A storage chamber 6 is provided inside the triangular pillow 3 , an air bag 5 is provided on the back cushion 4 , a discharge pipe 8 is fixedly connected to the air bag 5 , and the storage chamber 6 is communicated with the inner cavity of the air bag 5 through the discharge pipe 8 .

[0040] There are multiple airbags 5, which are buried in the cushion 4 and extend through the elastic support plate 2 to the inside of the triangular pillow 3. When the patient leans on the cushion 4, the airbag 5 will be squeezed, and the gas in the airbag 5 can be squeezed into the storage chamber 6 opened in the triangular pillow 3 through the discharge pipe 8, so that the interior of the storage chamber 6 is pressurized. When the patient is not leaning on the cushion 4, the gas entering the storage chamber 6 will re-enter the interior of the airbag 5, causing the airbag 5 to expand again.

[0041] A guide cylinder 12 is fixedly installed inside the triangular pillow 3, and a pressure rod 15 for pressing the pressure sensor 11 is elastically installed inside the guide cylinder 12. A first piston 16 is fixedly installed at the other end of the pressure rod 15, and the sliding of the first piston 16 is controlled by the pressure in the storage chamber 6.

[0042] The guide cylinder 12 is hollow and communicated with the inner cavity of the storage chamber 6. The pressure sensor 11 is arranged at one end of the guide cylinder 12 away from the airbag 5. By controlling the first piston 16 and the pressure rod 15 in the guide cylinder 12 to slide toward the pressure sensor 11, the pressure rod 15 can press the pressure sensor 11.

[0043] When the patient leans on the cushion 4, the gas in the multiple airbags 5 enters the interior of the storage chamber 6 through the exhaust pipe 8, so that the air pressure in the storage chamber 6 gradually increases, thereby pushing the first piston 16, causing the pressure rod 15 to slide toward the direction of the pressure sensor 11. In the above manner, the patient's weight can be indirectly measured, and at the same time, the pressure sensor 11 can be avoided from being set below the patient, causing discomfort to the patient. Although the pneumatic transmission method will reduce a certain detection accuracy, a certain threshold can be reserved, and the turning frequency can still be adjusted according to different body weights.

[0044] Clean water is stored inside the storage chamber 6, and a multi-connected U-shaped connecting pipe 7 is fixedly installed inside the storage chamber 6. The multi-connected U-shaped connecting pipe 7 is arranged inside one end of the triangular pillow 3 facing the cushion 4, and both ends of the multi-connected U-shaped connecting pipe 7 extend to both ends of the storage chamber 6.

[0045] When the patient leans on the cushion 4, the gas in the multiple airbags 5 will enter the interior of the storage chamber 6 through the discharge pipe 8, and press the clean water in the storage chamber 6. At this time, the clean water almost fills the storage chamber 6, which can improve the efficiency of the gas in the airbags 5 to discharge and press the water. When the water is pressed, the first piston 16 can be pushed by the water, which is better than using only gas to transmit pressure. At the same time, the filled water will also increase the weight of the triangular pillow 3, which can effectively prevent the displacement of the triangular pillow 3 on the bed.

[0046] A pressing plate 13 is slidably mounted inside the storage chamber 6 , and the outer wall of the pressing plate 13 is in contact with the inner wall of the storage chamber 6 .

[0047] When the top pressure plate 13 slides inside the storage chamber 6, the water can be squeezed toward one side. The water will not only be squeezed into part of the airbags 5, but also can be squeezed into one end of the multi-connected U-shaped connecting tube 7. When the water enters the airbags 5, the patient's back can be cooled down and kept cool, which can prevent the patient from sweating and causing skin damage due to lying on the triangular pillow 3 for a long time. The clean water in the storage chamber 6 can enter from one end of the multi-connected U-shaped connecting tube 7 and be discharged from the other end through the top pressure plate 13. As the top pressure plate 13 slides back and forth, the clean water can flow back and forth inside the multi-connected U-shaped connecting tube 7.

[0048] A driving motor 10 is fixedly installed inside the triangular pillow 3 , and a first reciprocating threaded rod 9 is fixedly installed on the output shaft of the driving motor 10 . The first reciprocating threaded rod 9 is connected to the top pressure plate 13 through threads.

[0049] By starting the driving motor 10 , the first reciprocating threaded rod 9 can be driven to rotate, and at the same time, the top pressure plate 13 can be driven to slide back and forth inside the storage chamber 6 , so that the water in the storage chamber 6 can continuously flow inside the multi-connected U-shaped connecting pipe 7 .

[0050] A transfer head 14 is fixedly installed inside the triangular pillow 3, one end of which extends to the inside of the airbag 5 and is fixedly installed with a deformation head 17. A second piston 18 is slidably installed inside the transfer head 14, and clean water is stored between the second piston 18 and the deformation head 17.

[0051] The deformation head 17 is located inside the airbag 5. When the second piston 18 is controlled to slide toward the deformation head 17, the second piston 18 will squeeze the clean water between the deformation head 17. At this time, the clean water will press the deformation head 17, causing the deformation head 17 to deform and expand toward the inside of the airbag 5. When the patient 5 leans on the cushion 4, the expanded deformation head 17 will contact the patient's back and perform pressure massage on the patient's back, which can not only provide a cool feeling on the patient's back, but also perform a certain massage, thereby improving the patient's comfort when lying on his side for a long time.

[0052] A second reciprocating threaded rod 20 is rotatably mounted on the multi-connected U-shaped connecting pipe 7 via a sealed bearing. The outer wall of the second reciprocating threaded rod 20 is threadedly connected to a transmission cylinder 19 , and the top end of the transmission cylinder 19 is fixedly connected to the second piston 18 .

[0053] A limit piece is provided on the transmission cylinder 19, which is used to limit the transmission cylinder 19 to only slide inside the transfer head 14 and not rotate. When the second reciprocating threaded rod 20 rotates, it can drive the transmission cylinder 19 to slide back and forth inside the transfer head 14, and at the same time drive the second piston 18 to slide back and forth inside the transfer head 14. When the second piston 18 slides toward the deformation head 17, the deformation head 17 can be deformed by squeezing water to achieve massage of the patient. When the second piston 18 slides in the direction away from the deformation head 17, the deformation head 17 can be released from deformation. By repeating the above operation, the massage effect on the patient can be achieved.

[0054] At the same time, the multiple U-shaped connecting tubes 7 are provided with multiple transfer heads 14 and deformation heads 17, which can ensure that multiple airbags 5 are provided with multiple transfer heads 14 and deformation heads 17 inside, thereby increasing the massage area.

[0055] One end of the second reciprocating threaded rod 20 extends to the interior of the multi-connected U-shaped connecting pipe 7 and is fixedly mounted with a water wheel blade 21 .

[0056] When the top pressure plate 13 slides back and forth inside the storage chamber 6, clean water can flow back and forth inside the multi-connected U-shaped connecting tube 7. When water flows through the multi-connected U-shaped connecting tube 7, it will impact the internal water wheel blades 21, causing the water wheel blades 21 to rotate. When the water wheel blades 21 rotate, it will drive the second reciprocating threaded rod 20 to rotate. Therefore, the second piston 18 can be controlled to slide back and forth inside the transfer head 14 to achieve massage of the patient's back.

[0057] Working principle: When the patient squeezes the airbags 5 on the cushion 4, the gas in the multiple airbags 5 enters the interior of the storage chamber 6 through the exhaust pipe 8, so that the air pressure in the storage chamber 6 gradually increases, thereby pushing the first piston 16, causing it to drive the pressure rod 15 to slide and press toward the direction of the pressure sensor 11, so that the patient's body weight can be monitored, and data calculations can be performed, and the ratio of pressure to time can be measured, so as to calculate the frequency of turning over of the patient with the current weight, thereby improving the patient's comfort while ensuring the rehabilitation effect.

[0058] When the top pressure plate 13 slides back and forth inside the storage chamber 6, water can be squeezed into part of the airbag 5, which can cool the patient's back and keep it cool. This can prevent the patient from sweating and causing skin damage when lying on the triangular pillow 3 for a long time. At the same time, clean water can flow back and forth inside the multi-connected U-shaped connecting pipe 7, controlling the rotation of the water wheel blades 21, driving the second reciprocating threaded rod 20 to rotate, and controlling the second piston 18 to slide back and forth inside the transfer head 14. By circulating the top pressure of the clean water in the transfer head 14, the patient's back can be massaged, thereby improving the comfort of the patient lying on his side.
