Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hospital bed with a multi-directional extension structure. Background Art

[0002] The size of a conventional single bed is fixed (single bed: the size is generally about 2.0m*0.9m), but the height and weight of the patients that the hospital needs to admit are different. If the user's height exceeds the length of the bed, the patient will not be able to stretch his body normally due to the limitation of the length and width of the bed; if the patient's height is much shorter than the length of the bed, when performing therapeutic positions, such as semi-recumbent position, low lying position, etc., he will shift due to insufficient height; some therapeutic positions have requirements on the length and width of the bed. For example, when a stroke patient is placed in a good limb position, the width of the bed is required to be wider than that of an ordinary bed to ensure the correct placement of the limbs and ensure safety.

[0003] In order to overcome this shortcoming, an extension bed frame is often added to the foot of the bed to accommodate users of different heights. There are two types of electric and manual types, but there is no extension and fixation for the width of the bed. Summary of the invention

[0017] Reference Figure 1-4 The embodiment of the present invention is a hospital bed with a multi-directional extension structure, which includes: a hospital bed body 1, telescopic rods 2 are slidably connected at both ends of the hospital bed body 1, and the ends of the two telescopic rods 2 away from the hospital bed body 1 are fixedly connected to brackets 3, and the upper ends of the two brackets 3 are fixedly connected to bed rails 4, which protect the safety of patients. Adjustment units 5 are provided on both sides of the lower end of the hospital bed body 1, sliding rods 6 are slidably connected at the front and rear ends of the hospital bed body 1, and the ends of the two sliding rods 6 away from the bed body 1 are fixedly connected to brackets 2 7, and the lower ends of brackets 1 3 and brackets 2 7 are provided with connecting holes, and support frames can be installed to improve the stability of the hospital bed body 1, and an extension unit 8 is provided at the lower end of the bed body 1; The two adjustment units 5 include a mounting seat 501 fixedly connected to the lower end of the bed body 1, the inner wall of the mounting seat 501 is rotatably connected to a gas rod 502 via a rotating shaft, and the output end of the gas rod 502 is rotatably connected to a connecting seat 503 via a rotating shaft. The length of the bed body 1 can be extended by the adjustment unit 5.

[0018] The upper end of the connecting seat 503 is fixedly connected to the bottom end of the bracket 3. The connecting seat 503 drives the bracket 3 to move.

[0019] The extension unit 8 includes an adjustment shell 801 fixedly connected to the lower end of the bed body 1, the inner wall of the adjustment shell 801 is rotatably connected to a bidirectional screw 802, the outer wall of the bidirectional screw 802 is fixedly connected to a gear 1 803, the outer wall of the bidirectional screw 802 and the two sides of the gear 1 803 are fixedly connected to sliding seats 804, the two sliding seats 804 are fixedly connected to the sides away from each other with connecting rods 805, and the inner wall of the adjustment shell 801 is provided with a driving unit 9. The width of the bed body 1 can be extended by the extension unit 8.

[0020] The two connecting rods 805 are L-shaped, and both connecting rods 805 penetrate one side of the adjustment shell 801. The connecting rod 805 penetrates the upper part of one end of the adjustment shell 801 and is fixedly connected to the bottom wall of the bracket 2 7. The bracket 2 7 is driven to move by the two connecting rods 805. The driving unit 9 includes a driving motor 901 fixedly connected to the inner wall of the adjusting shell 801, a rotating rod 902 fixedly connected to the output end of the driving motor 901, and a second gear 903 fixedly connected to the outer wall of the rotating rod 902.

[0021] Gear 2 903 is located on one side of gear 1 803, and gear 2 903 is meshed and connected with gear 1 803. The rotation of gear 2 903 drives gear 1 803 to rotate.

[0022] A controller 101 is installed on the front side of the bed body 1, and the controller 101 is electrically connected to the gas rod 502 and the drive motor 901. The controller 101 is convenient for the patient to control and extend the bed body 1.

[0023] Working principle: When the patient needs to extend the length of the bed body 1, the controller 101 starts the gas rod 502 to output the connecting seat 503 to drive the bracket 3 to move. The movement of the bracket 3 drives the telescopic rod 2 to extend out of the bed body 1, thereby changing the length of the bed body 1. When the patient needs to extend the width of the bed body 1, the controller 101 can be used to start the drive motor 901. The drive motor 901 outputs the rotating rod 902 to drive the gear 2 903 to rotate. The gear 2 903 rotates the bidirectional screw 802 on the gear 1 803 to rotate. The rotation of the bidirectional screw 802 will drive the two sliding seats 804 to move in opposite directions, thereby driving the bracket 2 7 at one end of the connecting rod 805 to move, and finally the width of the bed can be adjusted.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
