Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a prone position pressure sore prevention support device. Background Art

[0002] The main indication for prone ventilation is ARDS, also known as acute respiratory distress syndrome. Only a small amount of lung can be ventilated where there is consolidation in the lungs, that is, the distribution of consolidation and ventilation is uneven. When ventilating in the supine position, the consolidation area cannot be ventilated. After the body position is changed, due to gravity, the liquid diffuses to the inflated area. After ventilation, the expanded part of the lung can be increased, which can improve the ventilation effect and alleviate the symptoms of hypoxia. However, since patients who ventilate in the prone position need to wear a ventilator and maintain a prone posture for about twelve hours a day, it is very easy to cause pressure sores on the patient's face. For critically ill patients, adjusting the patient's posture and wearing the equipment midway also requires the cooperation of multiple people, and the operation is relatively complicated. Therefore, preventing facial pressure sores in patients who ventilate in the prone position and conveniently adjusting the patient's posture are extremely important for this treatment.

[0003] At present, the existing technology is to cooperate with at least two people, on the basis of preparing enough pillows, towels or blankets, first shake the bed flat, and assist the patient to turn over to the prone position. The first pillow is placed under the patient's chest or abdomen, and the second pillow is placed under the patient's forehead, leaving space for the oxygen mask. The patient's head is turned to a position that he feels comfortable, and then the oxygen tube is adjusted within the visible range. Make sure that the oxygen fills the air storage bag and the mask does not press on the patient's face. Then optimize the patient's position to make him feel comfortable. Finally, monitor the patient's blood oxygen saturation, respiratory rate and comfort in real time, and replace the towel on the surface of the patient's pillow at fixed intervals. At the same time, adjust the patient's head posture to avoid long-term side lying to damage the spine and cause pressure sores.

[0004] At present, the existing technology relies on medical personnel to complete the patient's prone posture adjustment and the wearing of corresponding equipment. The steps are extremely complicated and the patient has to be constantly asked when adjusting the posture angle, resulting in low operation efficiency and poor effect. In addition, the existing technology can only rely on medical personnel to assist in adjusting the head posture and mask at a fixed interval to avoid continuous compression of the face causing pressure sores. If this interval is too short, it will cause a sharp increase in the workload of medical personnel. If the interval is too long, it will cause great discomfort to the patient and the formation of pressure sores. It cannot be adjusted automatically and synchronously in real time, resulting in extremely inconvenient operation. In addition, only changing the pillow surface to contact the towel and adjusting the posture to prevent pressure sores is extremely poor compared to the real-time and uninterrupted implementation of facial ventilation and alternating stable support. The effect of preventing pressure sores is extremely poor. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a prone anti-pressure sore support device, which solves the problem that there is no automated and conveniently operated prone support adjustment structure in the prior art, resulting in complex manual operation, low efficiency and poor effect for medical staff, and lacks an automated facial support sensing intelligent adjustment structure, resulting in the inability to intelligently adjust the facial support in real time, causing pressure sores on the face.

[0035] like Figure 1-10 As shown, an embodiment of the present invention is: a prone anti-pressure sore support device, comprising an anti-pressure sore bed body 1, an inflatable limb support pillow is fixedly arranged on the top of the anti-pressure sore bed body, the inflatable limb support pillow comprises an inflatable foot support pillow 2, an inflatable abdomen support pillow 3 and an inflatable chest support pillow 4, the inflatable foot support pillow, the inflatable abdomen support pillow and the inflatable chest support pillow are all connected with the inflatable motor 5 through an inflatable tube, the inflatable motor is fixedly arranged at the bottom of the anti-pressure sore bed body, a limb movable hollow area 6 is opened on the anti-pressure sore bed body, a limb telescopic support plate 7 is arranged inside the limb movable hollow area, the limb movable hollow area is set according to the position range of the limbs of the human body when lying prone, the frame of the limb movable hollow area is rounded to prevent the patient from being scratched by sharp corners when moving the limbs, wherein the limb telescopic support plate comprises a flexible support plate body 8 whose size matches the limb movable hollow area, and an electric telescopic column 9 is fixedly arranged at the bottom of the flexible support plate body. The main function of the above structure is to be able to move the patient's limbs and improve the comfort of the patient in prone position by controlling the inflation state of the inflatable limb support pillow. The use of the limb movable hollow area in conjunction with the limb telescopic support plate is conducive to the realization that after the patient lies for a long time, the telescopic support plate can be lowered to empty the limb movable hollow area for the patient to move his limbs and place the injured limbs. For patients who are completely unconscious, medical staff can also use the telescopic support plate to support the limbs for up and down movements.

[0036] An anti-pressure sore head and face support pillow 10 is fixedly arranged at the upper end of the anti-pressure sore bed body, and the anti-pressure sore head and face support pillow includes a supporting elastic plate 11, a prone face breathing hole 12 is opened in the middle of the supporting elastic plate, and a rotating positioner 13 is fixedly arranged at the upper and lower ends of the prone face breathing hole, and the rotating positioner is fixedly arranged at the bottom of the supporting elastic plate. The main body of the rotating positioner is an electric rotating sleeve 14, and a bidirectional rotating slide rail 15 is opened in the electric rotating sleeve. A rotating slide plate 16 is slidably arranged in the bidirectional rotating slide rail, wherein one end of the rotating slide plate is connected to a rotating motor 17 fixedly arranged on both sides of the electric rotating sleeve, and the other end of the rotating slide plate is fixedly connected to a positioning support plate 18, and the support An anti-pressure sore massage flexible pad 19 is fixedly installed on the top of the supporting elastic plate, and the anti-pressure sore massage flexible pad includes a dot matrix floating raised massage plate 20 and a flexible pad breathable protective cover 21. The dot matrix floating raised massage plate is composed of an electric telescopic convex head 22 fixedly installed on the top of the supporting elastic plate in a dot matrix manner. A micro airway 23 for providing gas circulation is provided in the middle of the electric telescopic convex head. A constant temperature and humidity air supply machine 24 is connected to the micro airway through a pipeline. The constant temperature and humidity air supply machine is fixedly installed at the bottom of the supporting elastic plate. A dot matrix micro pressure sensor 25 is provided on the surface of the flexible pad breathable protective cover, and a humidity sensor 26 is provided on the surface of the flexible pad breathable protective cover.

[0037] A central controller 27 is fixedly arranged outside the anti-pressure sore bed, and is connected to the inflatable limb support pillow, the limb telescopic support plate, and the anti-pressure sore head and face support pillow through lines, and the dot matrix micro pressure sensor and the humidity sensor are connected to the central controller through wireless signals. The central controller can be a pure manual central controller or a voice-controlled central controller.

[0038] When implementing this embodiment, first let the patient lie on the anti-pressure sore bed in a prone position, so that the patient's face is aligned with the prone face breathing hole, and the patient wears the breathing mask he needs to wear, and then the central controller controls the inflation motor to inflate the inflatable foot support pillow, the inflatable abdomen support pillow and the inflatable chest support pillow respectively so that the inflation is stopped when the patient feels the best. When the patient's limbs become sore and swollen after lying for a long time, the central controller controls the electric telescopic column to drive the flexible support plate body downward, so as to ensure that the patient's limbs can directly extend from the limb activity hollow area for movement, while the limbs and trunk remain in the prone position. After completing the activity, the limbs are put back on the anti-pressure sore bed, and then the electric telescopic rod is controlled to rise back, so as to achieve state recovery.

[0039] For the anti-pressure sore care of the patient's face, it is necessary to set the rotation positioner to rotate at a fixed time according to the data transmitted back to the central controller by the dot matrix micro pressure sensor and humidity sensor, so that the rotation positioner can rotate the supporting elastic plate at a fixed angle at a fixed time under the data set by the central controller, thereby driving the anti-pressure sore massage flexible pad on the upper end of the supporting elastic plate to rotate and bend, and driving the patient's face on it to rotate and adjust the posture, thereby realizing the timed and flexible rotation of the patient's face to prevent the same facial area of ​​the patient from being compressed for a long time and causing pressure sores. At the same time, the massage mode can also be set according to the detected pressure value and humidity value, that is, under the control of the central controller, the electric telescopic convex head on the dot matrix floating convex massage plate is retracted in sequence at intervals, which has the effect of regular interval squeezing massage. At the same time, the constant temperature and humidity air supply machine provides constant temperature and humidity comfort gas under the control of the central controller, which is sprayed from the micro airway and passes through the flexible pad breathable protective cover to exchange and supplement the air at the contact point between the patient's face and the anti-pressure sore head and face support pillow, thereby improving comfort and preventing the formation of pressure sores caused by abnormal temperature and humidity.

[0040] This embodiment provides a prone anti-pressure sore support device with an automatic adjustment of the prone support structure, an automatic head posture adjustment structure, and an automatic facial support sensing intelligent mobilization structure. The inflatable limb support pillow is combined with the limb activity hollow area to facilitate the realization of an automatic and conveniently operated prone support adjustment structure, simplifying the manual operation of medical personnel and improving efficiency. The anti-pressure sore head and face support pillow that can automatically adjust the pillow posture and the micro-sensor and the fully covered micro-massage structure thereon are combined with a central controller to facilitate the realization of an automatic facial support sensing intelligent mobilization structure, ensuring real-time intelligent mobilization of the facial support, and avoiding pressure sores on the face through temperature and humidity control and continuous real-time massage. .

[0041] In this embodiment, arc-shaped guardrails are fixedly provided on the left and right sides of the anti-pressure sore bed body, which is helpful to prevent the patient from rolling off the bed unconsciously.

[0042] In this embodiment, a silicone protective gasket is fixedly provided on the edge of the prone facial breathing hole, which is beneficial to ensuring the safety of the patient's face when the patient's face comes into contact and is squeezed with the prone facial breathing hole.

[0043] In this embodiment, a voice control chip is installed inside the central controller, which is beneficial for the patient to completely control the support device by voice when there is no medical staff present, avoiding the inconvenience of standing up to operate the central controller.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
