Description

TECHNICAL FIELD

[0001] The application relates to the technical field of recuperation equipment, in particular to a pressure injury prevention device for bedridden patients. BACKGROUND

[0002] Surgery is a very common medical means, which can quickly eliminate lesions so as to make patients recover health. Since the incision after surgery will have a great sense of discomfort after the end of the anesthetic effect, the patient needs to be bedridden for a long time, due to the long time of skin contact with the bed surface and the pressure injury or pressure sore caused by the weight of the patient, for this, a pressure injury prevention device is installed under the bed sheet, so as to reduce the contact surface between the bed surface and the human body. The pressure injury prevention device of this type is a relatively traditional one and is also the most widely used one at present.

[0003] Although the existing pressure injury prevention device has certain effect, there are still certain limitations in the actual use process. Since the contact surface between the bed surface and the human body is reduced, the comfort of the patient lying on the bed is reduced, and when the patient is bedridden for a long time, the pressure injury still occurs, which cannot fundamentally solve the problem. For this, the application file proposes a pressure injury prevention device for bedridden patients, which aims to solve the above-mentioned problems. SUMMARY

[0004] The application adopts the following technical scheme: a pressure injury prevention device for bedridden patients, comprising a first support frame: the two sides of the first support frame are provided with travel holes in a drilling manner, a travel device is movably installed in the travel holes in a shaft hole matching manner, a connecting plate is fixedly installed on the bottom of the first support frame at positions close to the middle of the two sides through welding, a bottom plate is fixedly installed on the bottom of the connecting plate through welding, a power device is fixedly installed on the top of the bottom plate through bolt connection, a pressure sensing liquid supply device is fixedly installed on the front and back surfaces of the outer surface of the first support frame through bolt connection, guide pressure pipes are fixedly installed on the two sides of the outer surface of the pressure sensing liquid supply device through clamping, liquid guide pipes are fixedly installed on the bottom of the outer surface of the pressure sensing liquid supply device through clamping, the number of the liquid guide pipes is three, the guide pressure pipes and the liquid guide pipes are connected with the travel device, and a second support frame is fixedly installed on the bottom of the first support frame through welding at positions close to four corners.

[0005] Further, the stroke device comprises two side plates, one side of the side plate is provided with a bearing hole by drilling, the inside of the bearing hole is fixedly sleeved with a sealing bearing by shaft hole cooperation, the inside of the sealing bearing inner ring is fixedly sleeved with a massage device by shaft hole cooperation, the other side of the side plate is fixedly installed with a stroke rod near the middle, the stroke rod and the stroke hole are movably installed by shaft hole cooperation, one end of the stroke rod is sleeved with the power device by shaft hole cooperation, the outer surface of the side plate is provided with a limiting groove by grooving, and a rotating sleeve is movably sleeved through the limiting groove, and the outer surface of the rotating sleeve is fixedly installed with a contact film by sticking.

[0006] Further, the side plate, the sealing bearing and the contact film constitute a closed cavity, and the inside of the closed cavity is filled with water.

[0007] Further, the massage device comprises a rotating roller, the inside of the rotating roller is provided with a cavity, both ends of the rotating roller are fixedly installed with a connecting shaft, the connecting shaft is sleeved with the inside of the sealing bearing inner ring, the outer surface of the connecting shaft is provided with a limiting seat by integral casting, the limiting seats are distributed on the outer surface of the rotating roller in an array, and the inside of the rotating roller is movably installed with a telescopic block by shaft hole cooperation.

[0008] Further, one end of the pressure guide pipe is connected with the cavity in the inside of the rotating roller, and one end of the liquid guide pipe is connected with the inside of the closed cavity constituted by the side plate, the sealing bearing and the contact film.

[0009] Further, the power device comprises a telescopic machine, one end of the output shaft of the telescopic machine is fixedly installed with a connecting rod support by bolt connection, both ends of the connecting rod support are movably sleeved with connecting rods by shaft hole cooperation, one end of the connecting rod is movably sleeved with a stroke plate by shaft hole cooperation, one side of the stroke plate is provided with a connecting hole by drilling, and the connecting hole is sleeved with the stroke rod by shaft hole cooperation.

[0010] The application has the following beneficial effects.

[0011] 1. During the telescopic process of the telescopic machine, the stroke plate will reciprocate along the horizontal direction under the transmission of the connecting rod, at this time, the stroke plate will drive the whole stroke device to reciprocate in the inside of the stroke hole in the movement process of the stroke plate, so that the contact part of the stroke device with the patient in the bed changes, thereby avoiding the problem of pressure sores caused by the long-term contact of the skin surface of the patient in the bed with the bed surface and the extrusion of the body weight, and improving the practicality of the device.

[0012] 2. In the process of the overall reciprocating motion of the stroke device, the rotating roller will move relative to the human body and rotate along its axis as the center under the action, at this time the extension block in the protruding state will continuously contact the body, massage the bedridden patient, thereby promoting the blood flow of the part of the patient's body in contact with the bed surface, relieving the discomfort caused by long-term bedridden, and improving the comfort of the device.

[0013] 3. Under the action of the body weight of the patient, the extension block will be inserted into the inside of the limiting seat, thereby reducing the volume of the cavity inside the rotating roller and increasing the pressure, so that other extension blocks will be extended from the inside of the limiting seat under the action of the pressure, ensuring that the extension block can be in the extended state before contacting the human body during the rotation of the massage device, avoiding the problem that the extension block cannot be reset after being inserted into the inside of the limiting seat, reducing the massage effect, and improving the stability of the device during operation.

[0014] 4. When the patient's body weight is large, most of the extension blocks will remain inserted into the inside of the limiting seat, at this time the cavity inside the rotating roller is connected through one end of the pressure guide pipe, at this time the increase of the pressure inside the rotating roller will be transmitted to the pressure-sensitive liquid supply device through the pressure guide pipe, at this time the pressure-sensitive liquid supply device senses the increase of the pressure and injects more water into the inside of the closed cavity composed of the side plate, the sealing bearing and the contact film through the liquid guide pipe, thereby increasing the pressure inside the stroke device, achieving the effect of auxiliary support for the human body, avoiding the problem that the force between the rotating roller and the human body is too large when the bedridden patient has a large body weight, causing the patient to be uncomfortable, and further improving the practicality of the device.
