Description

A hospital bed that is easy for a patient to turn over

technical field

The invention relates to the field of medical equipment, in particular to a hospital bed that is convenient for a patient to turn over.

Background technique

Generally, patients who need long-term care, such as stroke, brain disease, central nervous system damage, and vegetative state, must lie on the bed for a long time because they do not have the ability to move. When a patient lies on the bed for a long time, it is very easy to develop bedsores, and once the bedsore disease occurs, it is very difficult to heal, which will not only bring great pain to the patient, but also bring a great burden to the caregivers.

Due to the lack of mobility, the patient must lie on the bed most of the time, so the design of the hospital bed has a great impact on the comfort of the patient and the convenience of taking care of the patient. The incidence of bedsores is greater than that of ordinary people, and the nursing work is more difficult and exhausting, so the general-purpose hospital beds are obviously not suitable for use, and specially designed special beds must be used.

The main cause of bedsores is that the bed and the patient's skin are pressed for a long time, resulting in poor blood circulation and poor ventilation, resulting in a sultry situation, resulting in skin ulceration. Nursing staff who take care of the patient must periodically turn the patient over to change the patient's center of gravity.

At present, when the server turns over the patient, the server relies entirely on the server to turn the patient over, which is very laborious, and the workload of the server is particularly large.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a hospital bed that is convenient for the patient to turn over, so as to reduce the workload of the server staff when turning the patient over.

To achieve the above object, the present invention adopts the following technical solutions:

A hospital bed that is convenient for a patient to turn over includes a bed frame, a turning air bag is arranged on the bed frame, and the turning air bag includes a first air bag and a second air bag both extending along the length direction of the bed frame, and the first air bag and the second air bag are both connected with inflatable air bags. Volume-adjustable inflation mechanism.

The principle and beneficial effects of this scheme are as follows:

The turning airbag is used to realize the turning of the patient on the bed. The specific turning principle is as follows: the inflation mechanism inflates the first airbag and the second airbag in the turning airbag, so that the first airbag and the second airbag bulge. Due to the inflation of the inflation mechanism The volume is adjustable. When the patient needs to be turned to one side, the inflation mechanism fills the first airbag and the second airbag with different amounts of gas, so that the first airbag is fully inflated, the second airbag is only partially inflated, and the first airbag is inflated. There is a height difference with the top of the second air bag. When the patient is lying on the first air bag and the second air bag, the side of the patient on the first air bag is higher than the side of the patient on the second air bag, and the patient is in a tilted state. The staff turns the patient over again, which can easily turn the patient; when the patient needs to turn over to the other side, the first air bag is only partially inflated, and the second air bag is fully inflated, so that the patient tilts to the other side, and the medical staff Then turn the patient over. When the patient is turned over, the whole body weight of the patient is concentrated on the contact part of the patient with the air bag on the lower side of the top (such as the patient's arm and waist), so that the contact part is subjected to relatively large pressure, and When the patient turns over, the contact part is located on the air bag on the lower side of the top, that is, the contact part is located on the uninflated air bag. The compression force on one arm and waist prevents the patient from feeling discomfort due to the pressure on one arm of the patient. And also because the oppressed part is the rotation axis of the patient's turning over, the oppressed arm and waist of the patient are wrapped by the airbag that is not full of air, forming a lateral limiting effect on the oppressed arm and waist when the patient turns over. , to avoid the problem that the patient's side arm and waist under compression will slip when the patient turns over, resulting in the failure of turning over.

Further, the inflatable mechanism includes an air pump and a three-way pipe, the three-way pipe includes 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, and the second air outlet pipe is communicated with the first air bag. The trachea can communicate with the second air bag, the first air outlet is provided with a first regulating valve sheet, and the second air outlet is provided with a second regulating valve sheet. The gas discharged from the air outlet end of the air pump enters the air intake pipe, and then is discharged from the first air outlet pipe and the second air outlet pipe. The gas in the first air outlet pipe enters the first air bag, and the gas in the second air outlet pipe enters the second air bag. For the inflation of the first airbag and the second airbag, the first regulating valve sheet is used to adjust the air flow in the first air outlet, and the second regulating valve sheet is used to regulate the air flow in the second air outlet.

Further, the first regulating valve plate is rotatably connected to the first air outlet pipe, and the rotation axis of the first regulating valve plate and the axis of the first air outlet pipe are coplanar and vertical, and the top of the first regulating valve plate is fixed with a first rotating shaft, The first rotation axis penetrates the top of the first air outlet pipe upward, the second regulating valve plate is rotatably connected to the second air outlet pipe, and the rotation axis of the second regulating valve plate and the axis of the second air outlet pipe are coplanar and vertical, and the second regulating valve plate is coplanar and perpendicular to the axis of the second air outlet pipe. A second rotating shaft is fixed on the top of the regulating valve plate, and the second rotating shaft upwardly penetrates the top of the second air outlet pipe. By rotating the angle between the first regulating valve plate and the axis of the first air outlet pipe, the gap between the first regulating valve plate and the inner wall of the first air outlet pipe is adjusted, so as to realize the adjustment of the air flow in the first air outlet pipe. The adjustment principle of the second regulating valve plate is the same as that of the first regulating valve plate.

Further, 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. When the first airbag and the second airbag are inflated and deflated, the intake ends of the first airbag and the second airbag also rise and fall. The air bag and the intake end of the second air bag are pulled during inflation and deflation.

Further, the first airbag and the second airbag are fixedly connected, and both the first airbag and the second airbag are mesh airbags. The ventilation can be realized through the mesh holes of the mesh airbag, the ventilation effect is good when the patient is lying on the hospital bed, and the effect of preventing the patient from developing bedsores is good.

Further, both sides of the bed frame are rotatably connected with reels extending along the length direction of the bed frame, a torsion spring is connected between the reels and the bed frame, a bed sheet is laid on the overturning airbag, and both sides of the bed sheet are respectively fixed and wound on the two scroll shafts. . The two sides of the sheet are stretched by two reels, which can flatten the sheet and avoid wrinkling. The two sides drive the reel to rotate in the forward direction, the torsion spring stores the force, and the sheets wound on the reel are released, which can keep the sheets flat during the patient's turning process, and also avoid the sheets being pulled after the sheets are lifted. If it is broken, when the first air bag or the second air bag is deflated, the sheet sinks back to its original position, and the torsion spring reverses, driving the reel to roll up the side of the sheet again.

Further, the bed frame is also slidably connected with two protective plates that can slide along the width direction of the bed frame, the protective plates are fixedly connected with a transverse rack, and the reel is sleeved with a drive gear that meshes with the rack. Since the patient is usually located in the center of the hospital bed, after turning the patient over, the patient will be at the edge of the hospital bed, and sometimes even accidentally fall out of the bed. The fixedly connected protective plate slides out of both sides of the bed frame to increase the width of the original bed frame and prevent the patient from falling out of the bed after turning over. Retracting into the bed frame does not affect the space occupied by the original hospital bed. In this solution, the airbag inflation is used as the driving force for the movement of the two protective plates, and no additional power is required to drive the movement of the two protective plates.

The principle that adopts the present invention to turn over the patient is as follows:

When the patient needs to turn to the left, the medical staff rotates the first rotating shaft 510 and the second rotating shaft 520 to make the first regulating valve plate 511 and the second regulating valve plate 521 rotate to the state shown in FIG. Turn on the switch of the air pump 4, the air pump 4 inflates the air inlet pipe 50 of the tee pipe 5, the gas entering the air inlet pipe 50 then enters the first air outlet pipe 51 and the second air outlet pipe 52, and the gas in the first air outlet pipe 51 enters the In the first air bag 2, the gas in the second air outlet pipe 52 enters the second air bag 3, because the angle between the first regulating 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 regulating valve sheet 521 in the second air outlet 52 coincides with the axis of the second air outlet 52 , so the air flow of the second air outlet 52 is greater than the air flow of the first air outlet 51 . The inflation volume is greater than the inflation volume in the first airbag 2, that is, the second airbag 3 is fully inflated, the first airbag 2 is only partially inflated, there is a height difference between the top of the first airbag 2 and the second airbag 3, and the patient lies on the first airbag 2. When the airbag 2 and the second airbag 3 are on, the patient is in a tilted state of left low and right high. At this time, the medical staff turns the patient over again, which can easily turn the patient over. When the patient is turned over, the whole body weight of the patient is concentrated on the contact part between the patient and the first airbag 2 (ie, the patient's left arm and waist), so that the contact part is subjected to relatively large compression force, and when the patient turns over, the The contact part is located on the first air bag 2 that is not full of air. Compared with the second air bag 3 that is full of air, the first air bag 2 that is only partially filled with air is softer, which reduces the impact on the patient's left arm and waist when the patient turns over. Compression force, to avoid the patient's discomfort due to the pressure on the patient's left arm and waist. And also because the compressed part is the rotation axis of the patient turning over, the compressed left arm and waist of the patient form a depression 10 on the uninflated first air bag 2, and the compressed left arm and waist of the patient are in the depression 10. The first airbag 2 that is not fully inflated inside forms a lateral limiting effect on the compressed left arm and waist of the patient when turning over, so as to avoid the problem of failure of turning over due to sliding of the compressed part of the patient when the patient turns over. When the patient is turned over, the deflation valves on the first airbag 2 and the second airbag 3 are opened, and the gas in the first airbag 2 and the second airbag 3 is discharged.

Since the two sides of the sheet 9 are respectively fixed and wound on the two reels 8 , and the reels 8 are connected with torsion springs, the temples on both sides of the sheet 9 can be flattened to prevent the sheet 9 from wrinkling. When 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 inflated, and the sheet 9 is lifted up, and the left and right sides of the sheet 9 drive the reel 8 to rotate in the forward direction, and the torsion spring is charged and wound. The bed sheet 9 on the reel 8 is released, which can keep the bed sheet 9 in a flat state all the time during the patient's turning over, and also can prevent the bed sheet 9 from being pulled and damaged after the bed sheet 9 is lifted up. When the first airbag 2 and the second airbag 3 are deflated, the sheet 9 sinks back to its original position, and the torsion spring reverses, driving the reel 8 to roll up the side of the sheet 9 again, so that the sheet 9 is always in a flat state. At the same time, when the reel 8 rotates in the forward direction, the driving gear 81 is driven to rotate, and the driving gear 81 drives the rack 70 to slide laterally, thereby driving the protective plate 7 fixedly connected with the rack 70 to slide out of both sides of the bed frame 1, increasing the original bed frame 1. Width, because the patient is usually located in the center of the bed, after turning the patient over, the patient will be at the edge of the bed, and sometimes even accidentally fall out of the bed. When the reel 8 is reversed under the action of the torsion spring, the reel 8 drives the driving gear 81 to reverse, and the protective plate 7 is retracted into the bed frame 1 again, without affecting the space occupied by the original hospital bed.

When the patient needs to turn to the right, the medical staff screw the first rotating shaft 510 and the second rotating shaft 520 to make the first regulating valve plate 511 and the second regulating valve plate 521 rotate to the state shown in FIG. The air flow in the first air outlet pipe 51 is greater than the air flow in the second air outlet pipe 52. At this time, the air pump inflates the first air bag 2 and the second air bag 3, so that the first air bag 2 is fully inflated and the second air bag 3 is only partially inflated Gas, the patient is in a tilted state of high left and low right. At this time, the medical staff can turn the patient over again, which can easily be turned over successfully.
