Description

Sickbed convenient for patient to turn over

Technical Field

The invention relates to the field of medical equipment, in particular to a sickbed convenient for a patient to turn over.

Background

Generally, patients who have to be cared for a long time, such as stroke, brain lesion, central nerve damage, and botanicals, have no mobility ability by themselves, and thus have to lie and lean on a bed for a long time. The patient lies on the bed for a long time, bedsore can be easily generated, once bedsore disease occurs, healing is not easy, great pain is brought to the patient, and great burden is brought to caregivers.

Since the patient has no mobility and must lie on the bed most of the time, the design of the hospital bed has a great influence on the comfort of the patient and the convenience of the patient care work, so that for the patient without mobility, the hospital bed for general use is obviously not suitable for use, and a specially designed special hospital bed must be used, because the probability of bedsore occurrence is higher than that of the general people, and the nursing work is more difficult and physical.

The main reasons of bedsore are poor blood circulation, poor ventilation and sultry caused by long-time pressing of the sick bed and the skin of the patient, and skin ulceration caused by the sultry. The nursing staff who attends to the patient must turn the patient timely to change the stressed center of gravity of the patient.

At present, when a servo person turns over a patient, the servo person can turn over the patient completely, which is very labor-consuming and has a large amount of labor.

Disclosure of Invention

The invention aims to provide a sickbed convenient for a patient to turn over so as to reduce the labor amount of a servo worker when the patient turns over.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a sick bed convenient to patient stands up, includes the bedstead, is equipped with the upset gasbag on the bedstead, and the upset gasbag is including first gasbag and the second gasbag that all extends along bedstead length direction, and first gasbag and second gasbag all link has the inflation mechanism of inflation volume adjustable.

The principle and the beneficial effect of the scheme are that:

the turning air bag is used for turning a patient on a sickbed, and the specific turning principle is as follows: the inflating mechanism inflates the first air bag and the second air bag in the overturning air bag to enable the first air bag and the second air bag to be inflated, because the inflating quantity of the inflating mechanism is adjustable, when a patient needs to turn over to one side, the inflating mechanism inflates different quantities of air into the first air bag and the second air bag to enable the first air bag to be full of air and the second air bag to be only inflated, a height difference exists between the tops of the first air bag and the second air bag, when the patient lies on the first air bag and the second air bag, one side of the patient, which is positioned on the first air bag, is higher than one side of the patient, which is positioned on the second air bag, and the patient is in an inclined state, and at the moment, medical personnel turn over the patient again, so that the patient can be turned over easily; when the patient needs to turn over to the other side, the first air bag is only filled with a part of air, the second air bag is filled with air, so that the patient inclines to the other side, and the medical staff turns over the patient. When the patient is turned over, the whole body weight of the patient is concentrated on the contact part of the patient and the air bag at the lower side of the top (such as one side of the arm and the waist of the patient), so that the compression force applied to the contact part is larger, and when the patient is turned over, the contact part is positioned on the air bag at the lower side of the top, namely the contact part is positioned on the air bag which is not filled with air. And because the pressed part is the rotating axis of the patient, the arm and the waist of the pressed side of the patient are wrapped by the air bag which is not filled with air, the transverse limiting function is formed on the arm and the waist of the pressed side of the patient when the patient turns over, and the problem that the patient fails to turn over due to the fact that the arm and the waist of the pressed side of the patient slide when the patient turns over is avoided.

Further, the inflation mechanism comprises an air pump and a three-way pipe, the three-way pipe comprises an air inlet pipe, a first air outlet pipe and a second air outlet pipe, the air inlet pipe is communicated with the air outlet end of the air pump, the first air outlet pipe is communicated with the first air bag, the second air outlet pipe can be communicated with the second air bag, a first adjusting valve plate is arranged in the first air outlet pipe, and a second adjusting valve plate is arranged in the second air outlet pipe. The gas that gives vent to anger of air pump end combustion gas gets into the intake pipe, discharges from first outlet duct and second outlet duct again, and in the first air outlet duct gas got into first gasbag, in the second air outlet duct gas got into the second gasbag to realize aerifing of first gasbag and second gasbag, first regulating valve piece was used for adjusting the airflow in the first air outlet duct, and the second regulating valve piece is used for adjusting the airflow in the second air outlet duct.

Furthermore, first regulating valve block rotates to be connected on first outlet duct, and the axis of rotation of first regulating valve block and the axis coplane of first outlet duct and perpendicular, first regulating valve block top is fixed with first axis of rotation, first axis of rotation upwards runs through first outlet duct top, second regulating valve block rotates to be connected on the second outlet duct, and the axis of rotation of second regulating valve block and the axis coplane of second outlet duct and perpendicular, second regulating valve block top is fixed with the second axis of rotation, the second axis of rotation upwards runs through second outlet duct top. The gap between the first adjusting valve plate and the inner wall of the first air outlet pipe is adjusted by rotating the angle between the first adjusting valve plate and the axis of the first air outlet pipe, so that the adjustment of the air flow in the first air outlet pipe is realized, and the adjusting principle of the second adjusting valve plate is the same as that of the first adjusting valve plate.

Furthermore, a hose is communicated between the first air outlet pipe and the first air bag, and a hose is also communicated between the second air outlet pipe and the second air bag. Because the inlet ends of the first air bag and the second air bag also lift along with the first air bag and the second air bag when the first air bag and the second air bag are inflated and deflated, the flexible pipe can adapt to the lifting of the inlet ends of the first air bag and the second air bag, and the inlet ends of the first air bag and the second air bag are prevented from being pulled when the first air bag and the second air bag are inflated and deflated.

Further, the first air bag and the second air bag are fixedly connected, and the first air bag and the second air bag are both net-shaped air bags. Can realize ventilative through the mesh of netted gasbag, it is effectual that patient's ventilation effect when lying on the sick bed prevents that patient from giving birth to decubital ulcer.

Further, the bedstead both sides all are rotated and are connected with the spool that extends along bedstead length direction, all link between spool and the bedstead has the torsional spring, and upset gasbag upper berth is equipped with the sheet, and the sheet both sides are fixed respectively and are twined on two spools. Prop up sheet both sides limit through two spools, can be with the sheet exhibition flat, avoid the sheet to wrinkle, after first gasbag or second gasbag aerify, first gasbag or second gasbag swell, lift the sheet on, sheet both sides limit drives the spool forward rotation, the torsional spring holds power, the winding is rolled out at epaxial sheet, can make patient in the in-process sheet that stands up and remain the state of exhibition flat throughout, also can avoid lifting back sheet on the sheet to be dragged and pull out simultaneously, after first gasbag or second gasbag gassing, the sheet sinks to resume the normal position, the torsional spring reversal, it rolls up the sheet side again to drive the spool.

Furthermore, still horizontal sliding connection has two can follow the gliding guard plate of bedstead width direction on the bedstead, and guard plate fixedly connected with is horizontal rack, and the cover is equipped with the drive gear with rack toothing on the spool. Because patient is located sick bed central authorities usually, turn over the back with patient, patient can be in the sick bed border, sometimes can drop outside the sick bed by accident even by accident, drive gear rotates when the spool corotation, drive gear drives rack lateral sliding, thereby drive the guard plate roll-off bedstead both sides with rack fixed connection, increase the width of original bedstead, it is outside the sick bed to avoid patient to drop after turning over, when the spool reverses under the torsional spring effect, the spool drives drive gear reversal, the guard plate retracts in the bedstead again, do not influence the occupation space of original sick bed, this scheme utilizes the gasbag to aerify the power as two blocks of guard plate motion, it drives two blocks of guard plate motions to need not extra power.

The principle of turning over the patient by adopting the invention is as follows:

when the patient needs to turn over to the left, the medical staff screws the first rotating shaft 510 and the second rotating shaft 520 to rotate the first adjusting valve plate 511 and the second adjusting valve plate 521 to the state shown in fig. 5, the medical staff turns on the switch of the air pump 4 again, the air pump 4 inflates the air inlet pipe 50 of the three-way pipe 5, the air entering the air inlet pipe 50 enters the first air outlet pipe 51 and the second air outlet pipe 52 again, the air in the first air outlet pipe 51 enters the first air bag 2, the air in the second air outlet pipe 52 enters the second air bag 3, because the included angle between the first adjusting valve plate 511 in the first air outlet pipe 51 and the axis of the first air outlet pipe 51 is an acute angle, and the second adjusting valve plate 521 in the second air outlet pipe 52 coincides with the axis of the second air outlet pipe 52, the air flow of the second air outlet pipe 52 is greater than the air flow of the first air outlet pipe 51, so that the inflation amount in the second air bag 3 is greater than the inflation amount, namely, the second air bag 3 is full of air, the first air bag 2 is only partially inflated, a height difference exists between the top of the first air bag 2 and the top of the second air bag 3, when a patient lies on the first air bag 2 and the second air bag 3, the patient is in an inclined state with a lower left and a higher right, and at the moment, medical personnel turn over the patient again, so that the patient can be turned over more easily. When the patient is turned over, the whole body weight of the patient is concentrated on the contact part of the patient and the first air bag 2 (namely the left arm and the waist of the patient), so that the compression force applied to the contact part is larger, and the contact part is positioned on the first air bag 2 which is not filled with air when the patient is turned over. And because the pressed part is the rotation axis of the patient, the pressed left arm and waist of the patient form a recess 10 on the first air bag 2 which is not filled with air, the pressed left arm and waist of the patient are wrapped by the first air bag 2 which is not filled with air in the recess 10, and the pressed left arm and waist of the patient form a transverse limiting effect when the patient turns over, thereby avoiding the problem that the patient fails to turn over due to the sliding of the pressed part when the patient turns over. When the patient turns over, the air release valves on the first air bag 2 and the second air bag 3 are opened, and the air in the first air bag 2 and the second air bag 3 is discharged.

Because two sides of the bed sheet 9 are respectively fixed and wound on the two reels 8, and the reels 8 are connected with the torsional springs, the two sides of the bed sheet 9 can be unfolded and flattened, and the bed sheet 9 is prevented from being wrinkled. After the first air bag 2 and the second air bag 3 are inflated, the first air bag 2 and the second air bag 3 are expanded to lift the bed sheet 9, the left side edge and the right side edge of the bed sheet 9 drive the reel 8 to rotate in the forward direction, the torsional spring stores force, the bed sheet 9 wound on the reel 8 is discharged, the bed sheet 9 can be always kept in a flat state in the turning process of a patient, and meanwhile, the bed sheet 9 can be prevented from being pulled and damaged after the bed sheet 9 is lifted. When the first air bag 2 and the second air bag 3 are deflated, the bed sheet 9 sinks to return to the original position, the torsion spring rotates reversely, the reel 8 is driven to roll up the side edge of the bed sheet 9 again, and the bed sheet 9 is kept in a flattening state all the time. Meanwhile, the driving gear 81 is driven to rotate when the scroll 8 rotates forwards, the driving gear 81 drives the rack 70 to slide transversely, so that the protection plate 7 fixedly connected with the rack 70 is driven to slide out of two sides of the bed frame 1, the width of the original bed frame 1 is increased, because the patient is usually positioned in the center of a hospital bed, after the patient turns over, the patient can be positioned at the edge of the hospital bed, sometimes even outside the hospital bed can be dropped carelessly, the protection plate 7 extending out of the bed frame 1 can prevent the patient from falling outside the hospital bed after turning over, when the scroll 8 rotates backwards under the action of the torsion spring, the scroll 8 drives the driving gear 81 to rotate backwards, the protection plate 7 retracts into the bed frame 1 again.

When a patient needs to turn over to the right, medical staff screws the first rotating shaft 510 and the second rotating shaft 520 to enable the first adjusting valve plate 511 and the second adjusting valve plate 521 to rotate to be in the state shown in fig. 6, so that the air flow in the first air outlet pipe 51 is larger than the air flow in the second air outlet pipe 52, the air pump inflates the first air bag 2 and the second air bag 3, the first air bag 2 is full of air, the second air bag 3 is only inflated with a part of air, the patient is in an inclined state with the left high and the right low, and the medical staff turns over the patient at the moment, so that the patient can easily turn over successfully.
