Description
Technical field
The present invention relates to the technical field with the counteracting bedsores sick bed for kowtowing back of the body function automatically, and in particular to one kind has automatic
Turn over the rehabilitation bed for kowtowing back of the body counteracting bedsores function.
Background technology
Bedsore also makes pressure sore be also known as pressure ulcer, is due to that local organization is pressurized for a long time, occur continuous ischemia, anoxic,
It is malnutritive and cause tissue fester downright bad.The problem of pressure ulcer is a generality in rehabilitation and nursing.According to relevant
Document report, 60,000 people are there are about every year and die from pressure sore concomitant symptoms.Paraplegia, chronic debilitating illness, large-area burns and depth stupor
It is Susceptible population Deng long-term bedridden patients.General hospital bedsore incidence is 2.5% ~ 8.8%, up to 11.6%, Patients of Spinal
Incidence 25% to 85%, and 8% is relevant with death, and Aged In-patientss incidence is 10% ~ 25%.
The generation for preventing bedsore is always the most important thing in basic nursing works, is the important of evaluation nursing quality
Problem in index, and nursery work.The generally acknowledged effective ways for preventing bedsore are exactly manually to turn over and kowtow the back of the body at present.
Kowtowing the concrete operation step of the back of the body is：Operator is typically chosen the right hand（Depending on patient posture, stand right in left side
Hand, left hand on the contrary.）Thumb is close to first articulations digitorum manus of forefinger, and four refer to and close up in bowl-shape, like possessing egg sample, hand in hand
Wrist is exerted oneself, and lifts 20 ~ 30 centimetres, and frequency is 60 ~ 80 beats/min, kowtows back of the body operation every time no more than 30 minutes.With 15 ~ 20 points
Clock is preferred.The time interval for kowtowing the back of the body every time is no more than two hours.
Therefore, it is the long-term bedridden patients such as paraplegia, chronic debilitating illness, large-area burns and depth stupor to turn over and kowtow the back of the body
In nursery work, the work that consumes one's strength very much.Due to operator's sense of responsibility, working attitude whether rectify, each one poor physical capacity
The presence of different etc. factor so that turn kowtows back of the body work quality and hardly results in guarantee.The number of also interim workload, also very
It is difficult to ensure that back of the body work is kowtowed in the turn of card every two hours once.

The course of work：As shown in Fig. 2 patient is lain on screen cloth 6, controller opens one of them（Such as right side）Reel 5
The second motor 52 and the 3rd motor 58, be moved to opposite side along rack 41 under the drive of the both ends second gear 51 of reel 5,
When reaching opposite side（Left side）When controller stop the rotation of the second motor 52 and the 3rd motor 58, screen cloth 6 is covered in patient's
Top, screen cloth 6 forms fixing device from the upper and lower parcel realized to patient, two reels 5 and screen cloth 6, when preventing that patient from turning over
Produce horizontal displacement.After the completion of wrapping up patient, controller starts fluid pressure drive device 10, drives supporting plate 19 to move down；
Controller inverts the second motor 52 of above-mentioned reel 5, while opens another（Left side）The second motor 52 and bed board of reel 5
3 two corresponding sides（Left side）The first motor 33 start rotate simultaneously, and steering it is identical with the second motor 52 of previous reel 5,
First gear 32 and second gear 51 is driven to be rotated on rack 41, so that bed board 3 and two reels 5 are simultaneously along track 4
Rotated around rotating shaft 31；When bed board 3 is by horizontally rotating vertical position, the block 7 on movable axis 31 encounters wherein side
On limit switch I 8, the first motor 33 stops operating.Now, patient is become by horizontal recumbency in the presence of screen cloth 6 and bed board 3
Lie on one's side, then controller controls the reversion of the first motor 33 to drive first gear 32 to be returned along rack 41, and bed board 3 is horizontal
State, now controller control fluid pressure drive device 10 stretch, drive supporting plate 19 to be supported the both sides of bed board 3, prevent upwards
Bed board 3 inverts, and realizes the lateral position of patient, completes the upset of patient；Now, automatic back of the body device of kowtowing is placed on bed board 3, together
Step cog belt 25 is meshed with second on the second master gear 28 and support shaft 27 on stepper motor 26 from gear 29 respectively, under
Slide rail 23 is placed on the rear side of patient on bed board 3, and upper slide rail 21 is fixed on track 4 by connection card 9, as shown in Figure 1；Control
Device, which opens mobile motor 12 and makes to kowtow back of the body ball 17, to be rotated while moves up and down around screw rod 15, when step-by-step movement 17 be moved to top or
During bottom, controller makes stepper motor 26 work, and synchronous cog belt 25 drives the horizontal direction of screw rod 15 to move a certain distance, real
Back of the body work now is kowtowed to patient；When screw rod 15 is moved to the other end from one end of glidepath 23, controller makes stepper motor 26
Reversion, then proceedes to kowtow the back of the body, after the completion of controller control stepper motor 26 and mobile motor 12 to stop operating.By upper slide rail 21 from
Remove, automatic back of the body device of kowtowing is removed from bed board 3, controller control fluid pressure drive device 10 is retracted downwards, is driven on track 4
Supporting plate 19 is moved down, controller control bed board 3 two used just now（Left side）First motor 33 turns to vertical position
Put, controller controls the second motor 52 of two reels 5 and above-mentioned（Left side）First motor 33 rotates simultaneously to be returned to along track
Raw bits, patient is converted into the position that lies low by lateral position, the second motor 52 reversion of the reel 5 on controller control top returns to just
Beginning position（Right side）, the screen cloth 6 on patient top is returned into original position, as shown in Figure 1.Time block opens the present apparatus one in every 2 hours
It is secondary, circulate above-mentioned steps.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
