Description

Technical Field

[0001] This utility model relates to the field of electric hospital bed structure technology, and in particular to an electric hospital bed. Background Technology

[0002] Electric hospital beds are mainly used to treat paralyzed patients (including paraplegia, hemiplegia, and quadriplegia) who are bedridden for a long time due to weakened physical strength, insufficient active movement of paralyzed limbs, and abnormal muscle tone, which can lead to various complications such as systemic muscle atrophy, joint stiffness, and orthostatic hypotension. They are also used for standing rehabilitation training for lower limb orthopedic patients, ankle rehabilitation training for patients with foot inversion or eversion, and standing rehabilitation training for patients with spinal nerve injury.

[0003] Existing electric hospital beds have foot rails that are fixed to the bed frame. Because the foot rails are fixed, caregivers cannot directly access the patient's feet for procedures like changing dressings. Medication can only be applied from the sides. For wounds on the inner ankle, the foot needs to be moved, which carries a risk of secondary injury. Furthermore, the fixed foot rails prevent the bed board from being extended. Therefore, an electric hospital bed is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric hospital bed includes an electric hospital bed beam frame, a bed frame body is provided on the right side of the electric hospital bed beam frame, the bed frame body includes an outer plate that is connected and fixed to the electric hospital bed beam frame, a guardrail is provided at the top of the outer plate, the guardrail includes a bed end rail, and the bottom end of the bed end rail is movably connected to the outer plate.

[0007] Preferably, the outer plate has a groove on its surface, and a shaft is inserted into the side of the outer plate through a through hole. A dial is connected to the outer end of the shaft. The shaft passes through the limiting block through the through hole. The limiting block is connected and fixed to the bottom right side of the bed end rail. By moving the dial, the dial pushes the shaft into the through hole of the limiting block, ensuring the stability of the bed end rail when it is laid flat.

[0008] Preferably, a support spring is connected to the outside of the dial, and a fixing plate is connected to the end of the support spring. The fixing plate is fixed to the side of the outer plate. When the bed end rail rotates and causes the limiting block to move, the limiting block moves to the groove of the outer plate. The through hole of the limiting block is matched with the insertion shaft, which facilitates the snap-fit ​​operation.

[0009] Preferably, the left side of the bed end rail has an inner groove, and two limiting springs are symmetrically connected to the inner wall of the groove. A lifting plate is connected to the left side of the limiting springs, and a threaded shaft is rotatably installed at the center of the right side of the lifting plate. The threaded shaft passes through the inside of the bed end rail through a threaded hole. By rotating and moving the threaded shaft in the threaded hole of the bed end rail, the lifting plate can be lifted and pushed, so that the lifting plate can be flush with the top of the electric hospital bed beam.

[0010] Preferably, the lifting plate surface is provided with an air cushion end, and the bottom end of the bed end rail is provided with two rectangular plate ends, and the bottom of the rectangular plate ends is provided with a plate groove adapted to the insertion shaft. When the bed end rail is placed upright, the rectangular plate ends at the bottom of the bed end rail are located above the insertion shaft. The insertion shaft can limit the rectangular plate ends of the bed end rail to ensure the stability of the bed end rail when it is placed upright.

[0011] Preferably, the right side of the bed end rail is symmetrically connected to two protruding shafts, and a buffer spring is connected to the right side of the protruding shaft. The end of the buffer spring is connected to a rubber strip. A guide wheel is rotatably installed at the corner of the outer plate. When the rubber strip is impacted, the elastic force of the buffer spring can buffer the rubber strip, reducing the chance of the caregiver being injured by a collision.

[0012] Preferably, the outer convex shaft and the outer side of the buffer spring are fitted with rubber sleeves, and the two ends of the rubber sleeves are respectively connected and fixed to the rubber strip and the side of the bed end frame. The rubber sleeves can cover the buffer spring and the outer convex shaft, thereby protecting the buffer spring.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up the bed frame and guardrails, the bed end rail can be folded down. Compared with the traditional structure, this device uses a dial to control the insertion shaft to disengage from the slot end of the lower plate of the bed end rail. By rotating the bed end rail, it can be aligned with the right side of the electric hospital bed beam. At this time, the insertion shaft can be pushed to move under the elastic force of the support spring, so that the insertion shaft is inserted into the limit block, and then the bed end rail is horizontally locked and fixed. After the bed end rail is folded down, the overall length of the electric hospital bed beam can be extended, and medical staff can apply medicine from multiple angles to ensure the convenience of medication application.

[0015] 2. By installing guardrails, the lifting plate can be raised. After the bed end rail is lowered, the threaded shaft can be twisted and rotated, moving within the threaded hole of the bed end rail to push the lifting plate. During this movement, the lifting plate is pushed up, allowing it to adapt to the top height of the electric hospital bed frame. At the same time, a buffer spring connects to a rubber strip on the outside of the bed end rail, providing a certain degree of protection to prevent caregivers from colliding with the bed end rail and getting injured.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4 An electric hospital bed includes an electric hospital bed beam 1, a bed frame body 2 is provided on the right side of the electric hospital bed beam 1, the bed frame body 2 includes an outer plate 21 that is connected and fixed to the electric hospital bed beam 1, a guardrail 3 is provided at the top of the outer plate 21, the guardrail 3 includes a bed end rail 31, and the bottom end of the bed end rail 31 is movably connected to the outer plate 21.

[0024] The outer plate 21 has a groove on its surface. A shaft 26 is inserted into the side of the outer plate 21 through a through hole. A dial 25 is connected to the outer end of the shaft 26. The shaft 26 passes through the inside of the limiting block 27 through the through hole. The limiting block 27 is connected and fixed to the bottom right side of the bed end railing 31.

[0025] A support spring 24 is connected to the outside of the dial 25, and a fixing plate 23 is connected to the end of the support spring 24. The fixing plate 23 is fixed to the side of the outer plate 21.

[0026] The left side of the bed end rail 31 has an inner groove, and two limiting springs 38 are symmetrically connected to the inner wall of the groove. A lifting plate 37 is connected to the left side of the limiting springs 38. A threaded shaft 36 is rotatably installed at the center of the right side of the lifting plate 37, and the threaded shaft 36 passes through the interior of the bed end rail 31 through a threaded hole.

[0027] The lifting plate 37 has an air cushion end on its surface, and the bottom of the bed end railing 31 has two rectangular plate ends, with a plate groove adapted to the insertion shaft 26 below the rectangular plate ends.

[0028] Two protruding shafts 32 are symmetrically connected to the right side of the bed foot rail 31, and a buffer spring 33 is connected to the right side of the protruding shaft 32. A rubber strip 34 is connected to the end of the buffer spring 33, and a guide wheel 22 is rotatably installed at the corner of the outer plate 21.

[0029] A rubber sleeve 35 is fitted on the outside of the protruding shaft 32 and the buffer spring 33, and the two ends of the rubber sleeve 35 are respectively connected and fixed to the rubber strip 34 and the side of the bed end rail 31.

[0030] When the bed end rail 31 rotates, the bed end rail 31 can drive the limiting block 27 to be built into the groove of the outer plate 21. At this time, the dial 25 can be turned to push the insertion shaft 26 into the through hole of the limiting block 27, ensuring the stability of the bed end rail 31 when it is laid flat. When the bed end rail 31 rotates and drives the limiting block 27 to move, the limiting block 27 moves to the groove of the outer plate 21. The position of the through hole of the limiting block 27 is matched with the insertion shaft 26. Under the elastic force of the support spring 24, the dial 25 can be pushed to move, so that the dial 25 can quickly push the insertion shaft 26 to perform displacement operation. By rotating and moving the threaded shaft 36 in the threaded hole of the bed end rail 31, the lifting plate 37 can be lifted and pushed, so that the lifting plate 37 can be flush with the top of the electric hospital bed beam 1, ensuring the overall flatness of the surface of the electric hospital bed beam 1.

[0031] When the lifting plate 37 is moved and raised, the air cushion end on the surface of the lifting plate 37 can improve the patient's comfort when lying flat. When the bed end rail 31 is placed upright, the rectangular plate end at the bottom of the bed end rail 31 is located above the insertion shaft 26. The insertion shaft 26 can limit the rectangular plate end of the bed end rail 31 to ensure the stability of the bed end rail 31 when it is placed upright. The rubber strip 34 can be connected by the buffer spring 33. When the rubber strip 34 is impacted, the elasticity of the buffer spring 33 can buffer the rubber strip 34, reducing the chance of injury to the caregiver. The buffer spring 33 and the protruding shaft 32 can be covered by the rubber sleeve 35, thereby protecting the buffer spring 33 and preventing the buffer spring 33 from pinching the hand or foreign objects from entering the buffer spring 33 and affecting the elasticity of the buffer spring 33.

[0032] Working principle: According to the appendix Figure 2 With appendix Figure 3 As shown, during use, the dial 25 can be turned to move the insert shaft 26, controlling the insert shaft 26 to disengage from the bottom plate groove of the bed end rail 31. At this time, the bed end rail 31 can be rotated so that it is flush with the outer plate 21 during rotation. At this time, the limiting block 27 moves into the groove of the outer plate 21, and pushes the dial 25 through the elastic force of the support spring 24. The movement of the dial 25 can push the insert shaft 26 through the inside of the limiting block 27, ensuring the stability of the outer plate 21 when it is placed horizontally.

[0033] Secondly, according to the appendix Figure 4 As shown, when the top plane of the electric hospital bed beam 1 is higher than the surface of the bed end rail 31, the end of the threaded shaft 36 can be moved in the threaded hole of the bed end rail 31 by rotating the threaded shaft 36. The movement of the end of the threaded shaft 36 pushes the lifting plate 37. The lifting plate 37 can be flush with the top of the electric hospital bed beam 1 during the upward movement, thus facilitating the flatness of the bed.
