Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hospital bed with a multi-directional extension structure. Background Technology

[0002] The standard dimensions of a single hospital bed are fixed (a single bed is generally around 2.0m x 0.9m). However, the height and weight of patients admitted to hospitals vary. If the user's height exceeds the length of the bed, the patient's body cannot stretch out properly due to the limitations of the bed's length and width. If the patient's height is significantly less than the length of the bed, they may shift during therapeutic positions such as semi-recumbent or low-lying positions due to insufficient height. Some therapeutic positions have requirements for both the length and width of the bed. For example, when positioning stroke patients in a proper limb position, the bed needs to be wider than a standard hospital bed to ensure correct limb placement and safety.

[0003] To overcome this drawback, extension frames are often added to the foot of hospital beds to accommodate users of different heights. These are available in both electric and manual versions, but neither offers extension or fixation for different bed widths. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a hospital bed with a multi-directional extension structure, comprising: a bed body 1, telescopic rods 2 slidably connected to both ends of the bed body 1, and brackets 3 fixedly connected to the ends of the two telescopic rods 2 away from the bed body 1; bed rails 4 fixedly connected to the upper ends of the two brackets 3, which protect the patient's safety. Adjustment units 5 are provided on both sides of the lower end of the bed body 1, and sliding rods 6 are slidably connected to both the front and rear ends of the bed body 1. Brackets 7 are fixedly connected to the ends of the two sliding rods 6 away from the bed body 1. Connection holes are provided at the lower ends of brackets 3 and brackets 7 for installing support frames to improve the stability of the bed body 1. An extension unit 8 is provided at the lower end of the bed body 1.

[0025] The two adjustment units 5 include a mounting base 501 fixedly connected to the lower end of the bed body 1. The inner wall of the mounting base 501 is rotatably connected to a gas spring 502 via a rotating shaft. The output end of the gas spring 502 is rotatably connected to a connecting seat 503 via a rotating shaft. The length of the bed body 1 can be extended by adjusting the units 5.

[0026] 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.

[0027] The extension unit 8 includes an adjustment shell 801 fixedly connected to the lower end of the bed body 1. A bidirectional screw 802 is rotatably connected to the inner wall of the adjustment shell 801. A gear 803 is fixedly connected to the outer wall of the bidirectional screw 802. Sliding seats 804 are fixedly connected to the outer wall of the bidirectional screw 802 on both sides of the gear 803. A connecting rod 805 is fixedly connected to the side of each sliding seat 804 that is far apart from each other. A drive unit 9 is provided on the inner wall of the adjustment shell 801. The width of the bed body 1 can be extended by the extension unit 8.

[0028] The two connecting rods 805 are L-shaped and both extend through one side of the adjusting housing 801. The connecting rods 805 are fixedly connected to the bottom wall of the bracket 7 at one end of the adjusting housing 801. The bracket 7 is moved by the two connecting rods 805.

[0029] The drive unit 9 includes a drive motor 901 fixedly connected to the inner wall of the adjustment housing 801. A rotating rod 902 is fixedly connected to the output end of the drive motor 901, and a gear 903 is fixedly connected to the outer wall of the rotating rod 902. The drive unit 9 can drive the extension unit 8 to extend the bed body 1.

[0030] Gear 2 903 is located on one side of gear 1 803, and gear 2 903 is meshed with gear 1 803. The rotation of gear 2 903 drives the rotation of gear 1 803.

[0031] A controller 101 is installed on the front side of the bed body 1. The controller 101 is electrically connected to the pneumatic spring 502 and the drive motor 901. The controller 101 allows the patient to control and extend the bed body 1.

[0032] Working principle: When the patient needs to extend the length of the bed body 1, the controller 101 starts the gas spring 502, which outputs the connecting seat 503 to drive the support 3 to move. The movement of the support 3 causes 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 starts the drive motor 901. The drive motor 901 outputs the rotating rod 902 to drive the gear 2 903 to rotate. The rotation of the gear 2 903 causes 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 support 2 7 at one end of the connecting rod 805 to move, ultimately realizing the adjustment of the width of the bed.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
