Abstract
Description
Technical Field
[0001] This application relates to a medical device, and particularly to a device for elevating the head of a turning bed for burn patients. Background Art
[0002] Turning beds are mainly applicable to patients with extensive burns, burns on the trunk or limbs, and those who have difficulty changing positions automatically or passively. Since the head of the bed cannot be elevated like a general hospital bed, in actual work, the front wheels of the turning bed can only be placed on a pier to elevate the head of the bed, which is beneficial for reducing swelling of the patient's head and face and preventing pulmonary infections.
[0003] However, this method requires multiple people to lift the head of the bed, and there is a patient on the bed. The entire bed is relatively heavy, not only requiring a large number of people but also being relatively laborious. Utility Model Content
[0004] In view of the above problems, this application aims to propose a device for elevating the head of a turning bed for burn patients, which can relatively easily elevate the head of the turning bed with one person's operation.
[0005] The device for elevating the head of a turning bed for burn patients of this application includes: a bottom plate, a floating plate, a first driving rod, a second driving rod, and a third driving rod;
[0006] The bottom plate is provided with a first mounting hole, a second mounting hole, and a third mounting hole;
[0007] The lower end of the first driving rod is rotatably mounted in the first mounting hole through a first bearing; a first sprocket is integrally formed on the lower part of the first driving rod; an external thread is formed on the upper part of the first driving rod;
[0008] The lower end of the second driving rod is rotatably mounted in the second mounting hole through a second bearing; a second sprocket is integrally formed on the lower part of the second driving rod; an external thread is formed on the upper part of the second driving rod;
[0009] The lower end of the third driving rod is rotatably mounted in the third mounting hole through a third bearing; a third sprocket is integrally formed on the lower part of the third driving rod; an external thread is formed on the upper part of the third driving rod;
[0010] The floating plate is formed with a first threaded hole, a second threaded hole, and a third threaded hole; the upper part of the first driving rod is threadedly engaged in the first threaded hole; the upper part of the second driving rod is threadedly engaged in the second threaded hole; the upper part of the third driving rod is threadedly engaged in the third threaded hole; a guiding plate is obliquely formed on one side of the floating plate;
[0011] The upper end of the first driving rod is fixedly installed with a handwheel;
[0012] A chain is tensionally mounted around a first sprocket, a second sprocket, and a third sprocket, and the chain meshes with the teeth of the first sprocket, the second sprocket, and the third sprocket respectively.
[0013] Preferably, the first driving rod, the second driving rod, and the third driving rod are distributed in a triangular shape on the bottom plate.
[0014] Preferably, the triangle is an isosceles triangle, and the first driving rod is located at the vertex position of the isosceles triangle.
[0015] Preferably, an arc-shaped groove is formed on the upper side of the floating plate for accommodating the casters at the bottom ends of the feet at the head position of the turning bed for burn patients.
[0016] After the turning bed elevation device for burn patients of the present application is inserted under the head of the turning bed, when the turning bed is pushed, the casters at the bottom ends of the feet of the head will roll along the guiding plate to the upper side of the floating plate and get stuck in the arc-shaped groove, making it not easy to slip off; at this time, by operating the handwheel, the height of the floating plate can be raised through the three driving rods, realizing the elevation of the head of the turning bed. The whole process can be implemented by only one person, saving manpower and reducing the physical consumption of the operator. Brief Description of the Drawings

[0022] Next, the turning bed elevation device for burn patients of the present application will be described in detail with reference to the accompanying drawings.
[0023] The turning bed elevation device for burn patients of the present application includes: a bottom plate 10, a floating plate 20, a first driving rod 30, a second driving rod 40, and a third driving rod 50.
[0024] The bottom plate 10 is provided with a first mounting hole 13, a second mounting hole 14 and a third mounting hole 15.
[0025] The lower end of the first driving rod 30 is rotatably mounted in the first mounting hole 13 through a first bearing; a first sprocket 31 is integrally formed on the lower part of the first driving rod 30; an external thread is formed on the upper part of the first driving rod 30.
[0026] The lower end of the second driving rod 40 is rotatably mounted in the second mounting hole 14 through a second bearing; a second sprocket 41 is integrally formed on the lower part of the second driving rod 40; an external thread is formed on the upper part of the second driving rod 40.
[0027] The lower end of the third driving rod 50 is rotatably mounted in the third mounting hole 15 through a third bearing; a third sprocket 51 is integrally formed on the lower part of the third driving rod 50; an external thread is formed on the upper part of the third driving rod 50.
[0028] The floating plate 20 is formed with a first threaded hole 23, a second threaded hole 24 and a third threaded hole 25; the upper part of the first driving rod 30 is threadedly engaged in the first threaded hole 23; the upper part of the second driving rod 40 is threadedly engaged in the second threaded hole 24; the upper part of the third driving rod 50 is threadedly engaged in the third threaded hole 25; a guide plate 21 is inclinedly formed on one side of the floating plate 20. The upper ends of the first driving rod 30, the second driving rod 40 and the third driving rod 50 extend above the floating plate.
[0029] A handwheel 32 is fixedly mounted on the upper end of the first driving rod 30.
[0030] A chain 60 is tensionedly mounted on the first sprocket 31, the second sprocket 41 and the third sprocket 51.

[0032] The triangle is an isosceles triangle, and the first driving rod 30 is located at the vertex position of the isosceles triangle.
[0033] An arc-shaped groove 26 is formed on the upper side of the floating plate 20 for accommodating the casters at the bottom ends of the feet at the head position of the turning bed for burn patients.
[0034] During use, first rotate the first driving rod through the handwheel, and the first sprocket on the first driving rod drives the chain to rotate, thereby driving the second driving rod and the third driving rod to rotate. The external threads on the upper parts of the first, second and third driving rods rotate in the corresponding first, second and third threaded holes, and the floating plate descends.
[0035] Insert the whole device under the lower side of the head of the bed, and then push the whole bed so that the casters of the two feet corresponding to the head of the bed roll along the guide plate onto the floating plate and get stuck in the arc-shaped groove.
[0036] The operator then rotates the handwheel, driving the chain to rotate through the rotation of the first driving rod, and the chain drives the second driving rod and the third driving rod to rotate; the external threads on the upper parts of the first, second, and third driving rods rotate in the corresponding first, second, and third threaded holes, the floating plate rises, and the head of the bed is lifted.
