Description

Technical Field

[0001] The invention belongs to the technical field of inflatable cushions, and in particular relates to an inflatable cushion for preventing pressure sores. Background Art

[0002] In order to reduce the occurrence of bone displacement, patients with fractures need to lie in bed in the same posture for a long time to rest. This makes the part of the patient's back that contacts the mattress very easy to develop pressure sores under long-term compression. Therefore, when dealing with patients with fractures or bedridden for a long time, hospitals always lay inflatable cushions on the bed to prevent and alleviate pressure sores caused by long-term bed rest.

[0003] Since most inflatable cushions use a cyclic inflation and deflation method, the surface of the cushion forms a wave shape and is combined with timed turning over to achieve the effect of preventing pressure sores. However, this method cannot effectively support the spine and is very likely to cause secondary injury to patients with spinal fractures. In addition, since turning over due to spinal fractures requires axial rotation, if the patient is heavy, a single nurse may not be able to perform the turning operation. At the same time, most current inflatable cushions operate autonomously and will not remind nurses to turn the patient over. Since most hospitals currently have a heavy workload, nurses are very likely to ignore the turning interval of the patient, which is not convenient for actual use. Summary of the invention

[0004] The object of the present invention is to provide an inflatable cushion for preventing pressure sores, so as to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, a pressure detector is fixedly installed on the top of the support column, and the detection end of the pressure detector is fixedly connected to the bottom of the base plate. Cylinders are symmetrically installed on the bottom of the base plate near its two ends, and the cylinders are sleeved on the ends of the support column. The pressure detector is located inside the cylinders.

[0009] Preferably, movable holes are symmetrically opened in the middle of the surface of the bottom plate away from the third air pipe, and a movable hole is opened on the air cushion, and the movable hole is located directly above the movable hole. A circular frame is slidably arranged in the movable hole, and the circular frame is passed through the movable hole on the air cushion, and the circular frame is located between the first air pipes. A second electric push rod is fixedly installed on the bottom of the bottom plate, and the second electric push rod is located between the two movable holes, and the output end of the second electric push rod is fixedly connected to the inner wall of the circular frame.

[0010] Preferably, a through hole is opened on the surface of the bed sheet, and the through hole is located directly above the circular frame and the third air pipe.

[0011] Preferably, two lifting holes are symmetrically provided on the surface of the bottom plate near its two sides, and an armrest is slidably provided inside the lifting hole, the armrest is a circular structure, and the armrest is kept flush with the third air pipe, and a connecting rod is fixedly connected to the inside of the armrest, the connecting rod is located above the bottom plate, and the two connecting rods are connected by a first cloth strip and a second cloth strip, and the first cloth strip and the second cloth strip are both located above the bed sheet, and two first electric push rods are symmetrically installed on the bottom of the bottom plate, the first electric push rods are located between the lifting holes, and the output end of the first electric push rod is fixedly connected to the inner wall of the armrest.

[0014] (1) The present invention is provided with a second air tube, a third air tube and a second air pump. When in use, the second air pump supplies air to the third air tube alone. Since the second air tube is not a U-shaped structure, when the first air pump is pumping air, the protrusions on both sides of the first air pump will collapse downward first, while the third air tube remains in place inside the fitting groove. As the air is pumped, the two sides of the patient's spine adjust the contact position with the fluctuation, and the spine is supported by the third air tube, thereby solving the problem that the inflatable cushion cannot effectively support the spine and easily causes spinal displacement.

[0015] (2) The present invention is provided with a time controller, a signal transmitter and a first electric push rod, etc. When the patient lies flat on the third trachea, the air pressure detector detects the change in the air pressure inside the third trachea and then starts the time controller to count. After the preset time is reached, the signal transmitter is started to notify the nurse to turn the patient over. When turning the patient over, it is only necessary to start the first electric push rod on one side, so that it can drive the second cloth strip and one end of the first cloth strip to move upward through the armrest, thereby assisting the nurse in turning the patient over, thereby eliminating the problem that the nurse is unable to help the patient turn over when dealing with a heavy patient.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4 As shown, the present invention provides the following technical solutions: an inflatable cushion for preventing pressure sores includes a bottom plate 13, baffles 15 are symmetrically installed on the top surface of the bottom plate 13 near the two ends thereof, and an air cushion 23 is laid on the top surface of the bottom plate 13, support columns 3 are connected to the bottom of the bottom plate 13 near the two ends thereof, and a first air pump 4 and a second air pump 10 are fixedly installed on the bottom of the bottom plate 13, the air cushion 23 is located between the baffles 15, and a first air pipe 20 and a second air pipe 21 are arranged inside the air cushion 23, the second air pipe 21 is located on one side of the inside of the air cushion 23, and the first air pipe 20 is installed on both sides of the second air pipe 21, and a fitting groove 29 is opened in the top surface of the second air pipe 21, and the fitting groove 29 is fitted inside A third air pipe 32 is provided, and the third air pipe 32 is perpendicular to the first air pipe 20, and the bottom of the third air pipe 32 near its two ends is respectively connected with an air inlet pipe 7 and an air outlet pipe 11, the air inlet pipe 7 and the air outlet pipe 11 pass through the air cushion 23 and the bottom plate 13 and are connected with the second air pump 10, the first air pipe 20 and the second air pipe 21 are connected with the first air pump 4 through the air pipe, the second air pump 10 is connected with the air inlet pipe 7 through a connecting pipe 9, an air pressure detector 18 and a time controller 8 are fixedly installed on the connecting pipe 9, a signal transmitter 1 is fixedly installed on the upper part of one side of a baffle 15 away from the air cushion 23, and the air pressure detector 18, the time controller 8 and the signal transmitter 1 are all connected through a data line.

[0024] Through the above technical solution, when a patient with a spinal fracture lies on the air cushion 23, the spinal fixator he wears is located directly above the third air tube 32. When the first air tube 20 and the second air tube 21 are repeatedly inflated and deflated by the first air pump 4, their surfaces present a wavy shape, thereby adjusting the contact area between the patient's skin and the air cushion 23, thereby achieving the effect of reducing the occurrence of pressure sores. However, since the third air tube 32 is supplied with air separately by the second air pump 10, and the second air tube 21 is a U-shaped structure, when the first air pump 4 draws air from the inside of the second air tube 21, the protrusions at both ends of the top of the second air tube 21 will collapse downward first, while the third air tube 32 arranged in the fitting groove 29 will remain in place, and then the spine and the spinal fixator are fixedly supported by the fixed third air tube 32, thereby solving the problem that the inflatable cushion 23 cannot effectively support the spine, which can easily cause spinal displacement.

[0025] In addition, when the patient lies on the third trachea 32, the third trachea 32 will be squeezed downward, causing the air pressure inside the third trachea 32 to increase. At this time, when the air pressure detector 18 detects a higher air pressure, it can be determined that the patient is in a lying position, and the time controller 8 is immediately activated and timed through the time controller 8. After the predetermined time is reached, a signal is sent out through the time controller 8 to notify the nurse to turn the patient over to prevent the skin of the spine from being squeezed by the third trachea 32 for a long time and causing pressure sores, thereby achieving the alarm effect. When the nurse completes the turning, the air pressure of the third trachea 32 gradually decreases. At this time, the air pressure detector 18 is activated again, and it is determined that the patient is in a lateral position at this time, and the time controller 8 is driven to reset the timing and restart the timing to achieve the effect of timed turning over.

[0026] At the same time, since the third air pipe 32 is embedded in the embedding hole, if it is necessary to restore the original effect of the air cushion 23, it is only necessary to disconnect the connection between the air inlet pipe 7 and the air outlet pipe 11 and the second air pump 10, so that the third air pipe 32 is in contact with the fixed connection of the air cushion 23 and the bottom plate 13, and then the disassembly can be completed by pulling the third air pipe 32 upward. The installation and adjustment steps are relatively few and it is convenient to use.

[0027] Furthermore, a second Velcro 33 is symmetrically installed on the side wall of the air cushion 23 close to the baffle 15, and the air cushion 23 is covered with a bed sheet 14, the bottom of the bed sheet 14 is adhered and fixed to the second Velcro 33, the third air tube 32 is rectangular, and a heating pad 25 is fixedly installed on the top of the third air tube 32.

[0028] Please refer to Figure 1-Figure 2 By installing the second Velcro 33, the bed sheet 14 can be directly fixed on the air cushion 23 by adhesion, which prevents the bed sheet 14 from moving when turning over. At the same time, during the fracture recovery period, the installed heating pad 25 can be used to heat the fracture area separately to increase the blood circulation in the fracture area and accelerate the recovery effect.

[0029] Furthermore, a pressure detector 12 is fixedly installed on the top of the support column 3, and the detection end of the pressure detector 12 is fixedly connected to the bottom of the base plate 13. A cylinder 2 is symmetrically installed at the bottom of the base plate 13 near its two ends. The cylinder 2 is sleeved on the end of the support column 3, and the pressure detector 12 is located inside the cylinder 2.

[0030] Please refer to Figure 3 When the patient lies on the air cushion 23, the pressure detector 12 will be pressed downward through the bottom plate 13 under the influence of gravity, and the downward pressure will be detected by the pressure detector 12 to calculate the patient's real-time weight. By controlling the first air pump 4 and the second air pump 10, the supporting force of the first air tube 20, the second air tube 21 and the third air tube 32 can be adjusted to improve the comfort of the air cushion 23 so that the patient can rest normally.

[0031] Furthermore, movable holes 30 are symmetrically opened in the middle of the surface of the bottom plate 13 away from the third air tube 32, a movable hole 31 is opened on the air cushion 23, and the movable hole 31 is located directly above the movable hole 30. A circular frame 5 is slidably arranged in the movable hole 30, and the circular frame 5 is passed through the movable hole 31 on the air cushion 23, and the circular frame 5 is located between the first air tubes 20. A second electric push rod 22 is fixedly installed on the bottom of the bottom plate 13, and the second electric push rod 22 is located between the two movable holes 30, and the output end of the second electric push rod 22 is fixedly connected to the inner wall of the circular frame 5. A through hole 24 is opened on the surface of the bed sheet 14, and the through hole 24 is located directly above the circular frame 5 and the third air tube 32, and the circular frame 5 is located below the patient's knees.

[0032] Please refer to Figure 1-Figure 3 and Figure 5 When the patient is in a lying state and the signal transmitter 1 sends a signal outward, the second electric push rod 22 starts automatically, driving the circular frame 5 to move upward through the movable hole 30 and the movable hole 31, until the top of the circular frame 5 passes through the bed sheet 14 through the through hole 24 and moves above the bed sheet 14, pushing the patient's knees upward from bottom to top, driving the patient's soles to gradually move and finally contact with the surface of the bed sheet 14. Finally, the second electric push rod 22 is reset, and the top of the circular frame 5 returns to the first trachea 20. Through the second electric push rod 22 and the circular frame 5, some preparations for axial reversal can be completed before the nurse arrives, so that after the nurse arrives, she only needs to manually adjust the patient's arms to perform the turning steps, simplifying the nursing steps and improving the nursing efficiency.

[0033] Furthermore, two lifting holes 28 are symmetrically provided on the surface of the bottom plate 13 near its two sides, and an armrest 6 is slidably provided inside the lifting hole 28. The armrest 6 is a circular structure, and the armrest 6 is kept flush with the third air pipe 32. A connecting rod 16 is fixedly connected inside the armrest 6. The connecting rod 16 is located above the bottom plate 13, and the two connecting rods 16 are connected by a first cloth strip 26 and a second cloth strip 27. The first cloth strip 26 and the second cloth strip 27 are both located above the bed sheet 14. Two first electric push rods 19 are symmetrically installed at the bottom of the bottom plate 13. The first electric push rod 19 is located between the lifting holes 28, and the output end of the first electric push rod 19 is fixedly connected to the inner wall of the armrest 6. The connecting rod 16 is wrapped with a first Velcro 17 near its two ends. The first cloth strip 26 and the second cloth strip 27 are both adhered to the connecting rod 16 through the first Velcro 17. The first cloth strip 26 and the second cloth strip 27 are respectively located under the patient's shoulders and buttocks.

[0034] Please refer to Figure 1-Figure 3When turning over a patient with a spinal fracture, after the second electric push rod 22 completes the adjustment of the legs and feet, the nurse also needs to manually adjust the patient's arms, and after completing all the adjustment steps, start the first electric push rod 19 on one side to drive the armrest 6 to move upward inside the lifting hole 28. Since the first cloth strip 26 and the second cloth strip 27 are located at the patient's shoulders and hips, when the connecting rod 16 drives one end of the first cloth strip 26 and the second cloth strip 27 to move upward, the first cloth strip 26 and the second cloth strip 27 can support the patient's shoulders and hips to turn the patient over, and the nurse only needs to perform auxiliary operations on the side. Since the turning thrust required for this method is mostly provided by machinery, nurses with less strength can also deal with patients with heavier weights alone, eliminating the current problem that nurses cannot help patients with heavier weights turn over.

[0035] Since the first cloth strip 26 and the second cloth strip 27 are adhered to the connecting rod 16 by the first Velcro 17, when the third air tube 32 is removed to restore the air cushion 23 to its original effect, only the ends of the first cloth strip 26 and the second cloth strip 27 need to be torn off to complete the removal and convenient use.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
