Description

Cushion for preventing bedsore that can be alternately lifted}

The present invention in more detail as an alternate floating bed sock prevention cushion, the air cell unit alternately floats through the information detected by the temperature sensor or pressure sensor to periodically change the pressure part of the bedsores to prevent the bedsores generated and It relates to an alternating buoyancy prevention cushion that can significantly reduce the risk of secondary infection at the site of pressure sores.

Pressure ulcers are pressured on one part of the body due to long standing posture and blood circulation disorders occur on the part of the body. That means ulcers. These pressure sores often occur in people with reduced mobility, such as elderly people, patients with neurological disorders or severe diseases. Various functional products have been released to prevent bedsores, and among them, a cushion for preventing bedsores is most used in terms of cost.

In this regard, referring to the prior art, Korean Patent No. 10-1298522, for example, disperses the pressure caused by the body's own weight by repeating a process of introducing and discharging air for each of the independent air cells divided into a plurality. It can reduce pressure sores, especially by detecting pressure point through pressure delivered to the cushion, recognizing the location of the sacrum bone, and injecting high temperature air into the air cell of the highest pressure point to perform high temperature air massage on the bone. Cushions to prevent pressure sores that reduce blood pressure, help blood circulation, remove skin moisture and prevent skin sores are suggested.

However, the Korean Patent No. 10-1298522 has a limitation in that its effect is lowered simply by detecting the highest pressure point and inducing air to prevent the occurrence of pressure sores. In addition, there is a fear that a high pressure air flows into the bedsores that are very susceptible to high temperatures, rather the bedsores are generated.

Republic of Korea Patent Publication No. 10-1298522 (2013.08.22.)

The present invention has been made to solve the problems of the prior art as described above, when the detected pressure is higher than the set pressure to inject more air to the detected pressure portion to prevent the occurrence of pressure sores Its purpose is to.

In addition, the pressure sensor unit 40 detects the pressure when the user is seated. (S2) The controller 60 indicates that the pressure detected by the pressure sensor unit 40 exceeds a first reference value set. If it is determined, air is further injected into the corresponding inflation portion. Will be able to prevent the occurrence of. Next, the control unit 60 determines whether the difference between the maximum value and the minimum value among the pressure values detected by the pressure sensor unit 40 exceeds the second reference value. If the control unit 60 determines that the difference between the maximum value and the minimum value among the pressure values detected by the pressure sensor unit 40 does not exceed the second reference value, the pressure sensor unit 40 again returns the pressure when the user is seated. (S2) If the control unit 60 determines that the difference between the maximum value and the minimum value among the pressure values detected by the pressure sensor unit 40 exceeds a second reference value, the user through the output unit 50 A signal indicating that posture correction is required is outputted. (S6) A signal indicating that posture correction of the user is required is transmitted through any one of the display 51, the speaker 53, and the vibration generating unit 53. It will be.

In addition, the control unit 60 may perform a function of recommending the support time of the first expansion unit 101 and the second expansion unit 102 alternately through pressure sensing using the pressure sensor unit 40. . Therefore, the user may continuously correct the posture through the control unit 60, and may balance the posture through alternating levitation of the first expansion unit 101 and the second expansion unit 102.
