Technical Field

[0001] This utility model relates to a medical weighing bed, and more particularly to a weighing device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In medical settings, patients often have limited mobility but require weight monitoring to aid in treatment. Current technology utilizes weighing beds to achieve this. These weighing beds typically add pressure sensors at the connection between the bed frame and the base frame. However, since the bed frame and base frame are usually stacked, the addition of the pressure sensors further occupies significant vertical space, increasing the bed's height and making it difficult for patients to get in and out. Furthermore, the exposed pressure sensor structure is more susceptible to corrosion and damage from impacts.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a weighing device that can further reduce the vertical height of the weighing device by setting a tube with a cavity in the second support and inserting the second end of the pressure sensor through the tube, which is also more conducive to protecting the pressure sensor structure.

[0006] To achieve the above objectives, this utility model discloses a weighing device, which includes:

[0007] The first support is composed of a plurality of first beams enclosing it.

[0008] The second support, the end of the second support is configured as a tube with a cavity;

[0009] A pressure sensor having a first end and a second end disposed opposite to each other, the first end of the pressure sensor being connected to the bottom of one of the first beams of the first bracket, and the second end of the pressure sensor being inserted into the tube of the second bracket.

[0010] The top of the second bracket is used to mount the bed, and the bed and the second bracket are used to provide a downward force to the second end of the pressure sensor. One of the first beams of the first bracket is used to provide an upward force to the first end of the pressure sensor.

[0011] As a further description of the above technical solution, the pressure sensor is configured as a regular rectangular block.

[0012] As a further description of the above technical solution, the weighing device also includes a fixing bolt, which passes through both the first end of the pressure sensor and one of the first beams of the first bracket at the corresponding position, so that the first bracket is fixedly connected to the pressure sensor.

[0013] As a further description of the above technical solution, the first end of the pressure sensor and one of the first beams of the first bracket at the corresponding position are fixed together by two fixing bolts that are spaced apart.

[0014] As a further description of the above technical solution, the weighing device also includes a plurality of movable wheels, which are spaced apart and installed at the bottom of the first support.

[0015] As a further description of the above technical solution, the second bracket has hollow tubes at both ends and is connected to the first bracket through two pressure sensors respectively.

[0016] As a further description of the above technical solution, there are two second supports, which are arranged in parallel, and the two second supports are connected to the first support respectively through four pressure sensors.

[0017] As a further description of the above technical solution, a crossbeam is connected between the two second supports, and the top of the crossbeam is connected to the bed frame.

[0018] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0019] The weighing device of this invention can be configured by having a hollow tube in the second support, and inserting the second end of the pressure sensor through the tube. The first end of the pressure sensor is installed at the bottom of one of the first beams of the first support, and the second end of the pressure sensor is inserted through the cavity of the tube in the second support. This makes the pressure sensor and the second support substantially located on the same horizontal level and sharing the same horizontal level, which indirectly reduces the total vertical height of the weighing device itself. Furthermore, the pressure sensor is mostly covered by the first and second supports, making it less susceptible to external corrosion and wear, and extending the service life of the device.

[0029] Please see Figure 1-3 This is a weighing device according to this embodiment, wherein the weighing device includes:

[0030] The first support 1 is composed of multiple first beams 11 enclosed by it.

[0031] The second support 2 has a tube with a cavity at its end.

[0032] Pressure sensor 3 has a first end and a second end that are arranged opposite to each other. The first end of pressure sensor 3 is connected to the bottom of one of the first beams 11 of the first support 1, and the second end of pressure sensor 3 is inserted into the tube of the second support 2.

[0033] The top of the second bracket 2 is used to mount the bed, and the bed and the second bracket 2 are used to provide a downward force to the second end of the pressure sensor 3. One of the first beams 11 of the first bracket 1 is used to provide an upward force to the first end of the pressure sensor 3.

[0034] For the above structure, during installation, the operator needs to insert at least part of the second end of the pressure sensor 3 into the tube formed at the end of the second bracket 2, and fix the second end of the pressure sensor 3 to the inner wall of the tube formed at the end of the second bracket 2. The specific connection method can be to use an external fastener to pass through the tube of the pressure sensor 3 and the second bracket 2, and fix the first end of the pressure sensor 3 to one of the first beams 11. The specific connection method can be to use a fixing bolt 4 to pass through the pressure sensor 3 and the first beam 11, and use the pressure sensor 3 as an intermediate connector to fix the first bracket 1 and the second bracket 2 to each other.

[0035] With the above structure, in use, the operator first reads the current reading of the pressure sensor 3 in a static state and resets it to zero. Then, the patient to be tested is arranged to lie flat on the bed at the top, so that the load on the second support 2 increases and is supported by the first support 1 on the bottom side. The force sensed by the pressure sensor 3 changes, so the operator can obtain the corresponding weight measurement reading at this time.

[0036] In the above structure, since the second end of the pressure sensor 3 passes through the cavity of the tube of the second support 2, the pressure sensor 3 and the second support 2 are actually located on the same horizontal layer and share the same horizontal layer, which indirectly reduces the total vertical height of the weighing device itself, and makes the pressure sensor 3 of the weighing device mostly covered by the first support 1 and the second support 2, making the pressure sensor 3 less susceptible to external corrosion and wear, and extending the service life of the device.

[0037] Furthermore, the pressure sensor 3 is configured as a regular rectangular block. In this embodiment, the second bracket 2 is also configured as a square steel pipe with a size matching it, and its size is slightly larger than the cross-section of the pressure sensor 3 to facilitate the insertion of the rectangular block.

[0038] Furthermore, the weighing device also includes fixing bolts 4, which pass through both the first end of the pressure sensor 3 and one of the first beams 11 of the corresponding first support 1, thereby fixing the first support 1 to the pressure sensor 3. Specifically, the first end of the pressure sensor 3 and one of the first beams 11 of the corresponding first support 1 are fixed together by two spaced-apart fixing bolts 4. Specifically, the two spaced-apart fixing bolts 4 are arranged along the extension direction of the rectangular block pressure sensor 3 to improve the stability of the fixation.

[0039] Furthermore, the weighing device also includes multiple movable wheels 5, which are spaced apart and mounted on the bottom of the first support 1. For details, please refer to [link to relevant documentation]. Figure 1 In this embodiment, the first support 1 is formed by four first beams 11 forming a rectangular frame. There are four movable wheels 5, which are respectively set at the four corners of the first support 1 to provide better support stability for the first support 1.

[0040] Furthermore, the second support 2 has hollow tubes at both ends and is connected to the first support 1 via two pressure sensors 3. There are two second supports 2, arranged in parallel, and connected to the first support 1 via four pressure sensors 4. Based on the rectangular first frame, in this embodiment, the two second frames 2 form two parallel longitudinal supports along the long side of the rectangle. The pressure sensors 3 at the four connection points with the first support 1 provide stable force detection, improving weighing accuracy.

[0041] Furthermore, a crossbeam 6 connects the two second supports 2, and the top of the crossbeam 6 is connected to the bed frame. Specifically, in this embodiment, there are two crossbeams 6, which are respectively located near the two short sides of the first support 1 of the rectangular frame, and are used directly to provide stable four-legged support for the bed frame at the top with the help of related connectors.
