Description

A hospital bed for assisting patients to automatically turn over and transfer

technical field

The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to a hospital bed for assisting patients to automatically turn over and transfer.

Background technique

At present, more than 13% of the population in my country is over 60 years old and the number is still increasing. The risk of developing many diseases increases with age. According to relevant statistics, more than 30 million patients in my country have different degrees of disability. The most common state of disability is the inability to move voluntarily and to turn over in bed voluntarily. Long-term bed rest will cause damage to other physiological functions. Because the patient cannot move voluntarily, the continuous pressure on the same part of the body will cause poor blood circulation, and at the same time, the nerve will be damaged, which will cause local necrosis of the part to form bedsores. Therefore, it is particularly important to help the patient to turn over frequently.

Compared with the huge number of patients, my country's medical resources are stretched. And to help patients turn their bodies, this places a great physical burden on the nursing staff. Most of the existing medical bed equipment in our country are some low-cost, low-tech and single-function hospital bed products. Automatic, efficient patient care is not available.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the defects of single function of the hospital bed in the prior art and the large physical burden on the patient to turn over by manpower, and to provide a hospital bed that can assist the patient to automatically turn over and transfer.

The technical scheme adopted by the present invention to solve its technical problems is:

Further, a beam clamping frame is clamped on the beam, a bearing seat is fixedly installed on the beam clamping frame, and the swing plate is installed on the bearing seat through a trunnion.

Further, an auxiliary pipe arranged in parallel with the unpowered roller is also connected between the two swinging plates symmetrically arranged in the front and rear.

Further, an auxiliary pipe end is fixed on the swing plate by bolts, the auxiliary pipe is sleeved outside the auxiliary pipe end, and is fixed by a pin shaft radially passing through the two.

Further, a vertical pipe flange is fixed on the swing plate by bolts, and the inner side of the vertical pipe flange has a vertical pipe installation convex shaft; the vertical pipe is sleeved outside the vertical pipe installation convex shaft, and passes through the vertical pipe installation convex shaft. A tapered pin penetrating both radially is fixed.

Further, armrest mechanisms are also installed on the longitudinal beams on the left and right sides of the bed frame.

Further, a fixing slot is installed on the longitudinal beam, a guardrail fixing plate is fixed at the lower end of the fixing slot, and the mounting plate of the handrail mechanism is fixed on the guardrail fixing plate by bolts.

Further, the armrest mechanism includes an armrest plate, a first link and two second links arranged in parallel on both sides of the first link, and both ends of the first link and the second link are respectively Pinned to the mounting plate and the handrail plate.

Further, headboards are also installed on the front and rear sides of the bed frame.

The beneficial effects of the hospital bed for assisting the patient to automatically turn over and transfer are as follows:

1. By rotating the rocker, the lead screw is driven to rotate in or out of the lead screw sleeve to extend or shorten the total length of the lead screw and the lead screw sleeve, and then pull the vertical tube to move, and the vertical tube movement makes the swing rod swing , the height of the unpowered rollers set on the swing rod can be adjusted; by adjusting the different heights of the unpowered rollers on both sides of the bed frame, and driven by the powered rollers, the patient sleeping on the transmission cloth can be automatically turned over.

2. Replace the traditional work of manpower to help patients turn over with electric drive to reduce the labor intensity of medical staff.

3. The structure is compact, and the size of the normal hospital bed is equivalent, saving the tight hospital space resources.

4. The existing ordinary hospital beds can be directly modified, which greatly reduces the cost of hospital bed renewal.

5. The operation is simple, only need to shake the rocker by hand to adjust the height of the unpowered drum, and then the bed shape in the turning state and the non-working state can be switched.

6. The armrest mechanism can be rotated, and the armrest mechanism can be rotated up or down as required.

In order to protect the patient from being turned out of the bed during the turning process, armrest mechanisms are also installed on the longitudinal beams 31 on the left and right sides of the bed frame 3 . Referring to FIG. 2 , a fixed slot 21 is installed on the longitudinal beam 31 , a guardrail fixing plate 22 is fixed at the lower end of the fixing slot 21 , and the mounting plate 29 of the handrail mechanism is fixed on the guardrail fixing plate 22 by bolts. As shown in FIG. 7 , the armrest mechanism includes an armrest plate 23 , a first link 24 and two second links 25 arranged on both sides of the first link 24 in parallel. Both ends are pinned to the mounting plate 29 and the armrest plate 23, respectively.

Headboards 26 are also installed on the front and rear sides of the bed frame 3 .

Referring to FIG. 6 , two ends of the longitudinal beam 31 are installed with fixing slot mounting brackets, the corner brackets 28 are fixed on the fixing slot mounting bracket by bolts, and both ends of the electric drum are installed through the corner brackets 28 .

The concrete working principle and process of the present invention are:

Normally, the embodiment of the present invention is an ordinary hospital bed, and the patient sleeps on the transmission cloth (sheet). When the patient needs to turn over, the nursing staff rotates the rocker 10 on one side of the bed frame 3 , and the total length of the lead screw 9 and the lead screw sleeve 7 is shortened when the rocker 10 rotates, thereby pulling the vertical tube 2 to the left and right of the bed frame 3 The two sides move, under the pulling of the vertical pipe 2, the swing plate 4 rotates around the trunnion 17 and the unpowered roller 5 rises, and the transmission cloth on this side is raised, and when it rises to a certain height, the rocker stops shaking 10. At this time, due to the self-locking function of the thread before the lead screw 9 and the lead screw sleeve 7, the height of the unpowered roller 5 is locked, and the powered roller 1 is started. The powered roller 1 drives the patient sleeping on the transmission cloth from low to low. High movement, and then realize automatic rollover. In order to ensure the safety of turning over, the armrest board 23 must be raised when turning over, so as to protect the patient from falling on the left and right sides of the bed frame 3 . The armrest board 23 can be rotated and lowered as needed when changing bedding or when a doctor is checking a patient.

On the other hand, if one end of the transmission cloth is wrapped around the power drum 1 of one bed and the other end is wrapped around the power drum 1 of the other bed, the transfer of the patient between the two beds can be realized.

It should be understood that the specific embodiments described above are only used to explain the present invention, but not to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
