Description

Technical Field

[0001] The utility model relates to a circuit board, in particular to a circuit board capable of being weighed. Background Art

[0002] Currently, hospitals store liquid medications in test tubes, which are then placed in drawers for safekeeping. However, when stored in drawers, medical staff have no way of knowing whether there is any medication left in the tubes or how much is left. This leads to medical staff having to open the drawer and take it out before making a final decision when they need it. This wastes time and can even lead to missing the optimal time to administer the medication. Utility Model Content

[0003] The first object of the utility model is to provide a circuit board, which can automatically weigh the circuit board and transmit the signal to the control background.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0005] A circuit board includes a control board. The control board is provided with a plurality of weighing sensors. Each weighing sensor is electrically connected to a controller. The controller transmits the obtained weight signal to a control background.

[0006] Furthermore, the weighing sensors are circular in shape and of different sizes.

[0007] Furthermore, the control panel is rectangular in shape.

[0008] Furthermore, the control board is provided with a plurality of fixing holes, and the fixing holes are used to fix the control board.

[0009] Another object of the present invention is to provide a drawer that can automatically weigh and determine the presence or absence of medicines.

[0010] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0011] A drawer comprises a circuit board as described in the above embodiment, a drawer body and a chassis; the circuit board is fixed between the drawer body and the chassis, and the chassis is connected to the drawer body for wrapping the circuit board.

[0012] Furthermore, it includes a storage position, which is circular; the storage position includes a storage hole and a fixing plate, and the fixing plate is connected to the bottom of the storage hole and is adapted to the storage hole.

[0013] Furthermore, the weighing sensor is arranged at the bottom of the fixing plate, and the weighing sensor is adapted to the storage hole.

[0014] Furthermore, the drawer body is provided with a plurality of connection holes, and the connection holes are adapted to and correspond to the fixing holes one by one.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] By adding a weighing sensor to the control panel, this utility model automatically weighs items placed on the panel. Based on the measured weight and the weight of an empty test tube, it can determine whether the test tube still contains medication. Furthermore, based on the density of the medication, the remaining volume is determined to determine whether the remaining amount meets the required usage. By automatically weighing items, this utility model saves medical personnel the time and cost of opening drawers for inspection, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1

[0020] like Figure 1 As shown, a circuit board includes a control board 1, and a plurality of weighing sensors 2 are provided on the control board 1. Each weighing sensor 2 is electrically connected to a controller, and the controller transmits the obtained weight signal to the control background. The weighing sensors 2 are circular in shape and of different sizes. The control board 1 is rectangular in shape. The control board 1 is provided with a plurality of fixing holes 3, which are used to fix the control board 1. The weighing sensor 2 can automatically weigh the items placed on the control board 1, and can determine whether there are still drugs in the test tube based on the weighed weight and the weight of the empty test tube. This saves the time cost of medical personnel opening drawers for inspection and improves work efficiency.

[0021] Example 2

[0022] like Figure 2As shown, a drawer includes a circuit board as described in the above embodiment, a drawer body 4, and a chassis 5. The circuit board is fixed between the drawer body 4 and the chassis 5, and the chassis 5 is connected to the drawer body 4 to enclose the circuit board. After weighing the medicine and test tubes, the remaining volume of the medicine can be determined based on the weight of the empty test tube and the density of the medicine, thereby determining whether the remaining volume meets the required usage. The drawer body 4 includes storage locations, each of which is circular. The storage locations vary in size, including at least two different storage locations, to accommodate medicines of different sizes. The storage locations include a storage hole 6 and a fixing plate 7, which is connected to the bottom of the storage hole 6 and fits in with the storage hole 6. The fixing plate 7 ensures safer access to the test tubes, preventing them from breaking and causing danger. The load cell 2 is located at the bottom of the fixing plate 7 and fits into the storage hole 6. The drawer body 4 is provided with multiple connection holes, which match and correspond to the fixing holes 3.

[0023] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
