Description

Technical Field

[0001] The utility model belongs to a weighing device with automatic feeding or unloading for weighing batch materials, in particular to a medical automatic counting device. Background Art

[0002] Liquid medical consumables need to be properly stored and managed in liquid storage cabinets before use to ensure the safety of liquid medical consumables. However, the current management of liquid medical consumables in the ICU intensive care unit of the hospital is to store liquid medical consumables in a storage cabinet with a label. When they need to be taken, the medical staff will take out the liquid medical consumables stored in the storage cabinet under the guidance of the label, and count them before and after taking them. In the process of managing liquid medical consumables using existing liquid storage cabinets, manual counting and statistics are laborious and inefficient. Although some prior art has improved liquid storage cabinets, such as a medical consumables intelligent identification storage cabinet disclosed in the utility model patent application with application number 202310475362.5, an intelligent identification management structure for recording the number and service life of stored medical consumables is added to the cabinet body with a storage cavity structure. However, this solution also requires manual handling and movement of the centrally stored materials, which increases the workload of medical staff. Therefore, the liquid storage cabinet improved by the prior art is difficult to meet the storage management needs in practical applications. Utility Model Content

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0016] The following examples further illustrate the content of the utility model, but should not be construed as limiting the utility model. Without departing from the spirit and essence of the utility model, modifications or replacements made to the methods, steps or conditions of the utility model are within the scope of the utility model.

[0017] Some Figure 1-4 The medical automatic counting device involved in the embodiment described at least comprises: Figure 1 The mechanical structure shown includes one or more hoppers 1 and a conveying mechanism 3 for moving the hopper 1, wherein the conveying mechanism 3 includes a lifting mechanism 31 and a horizontal conveying mechanism 32, wherein the horizontal conveying mechanism 32 includes an electromagnetically driven roller 321 arranged on the bottom surface of the hopper, and an electromagnetic horizontal conveying rail 322 which can be electromagnetically coupled with the electromagnetically driven roller 321 and limit the position of the electromagnetically driven roller 321.

[0018] exist Figure 1 Some embodiments based on the invention also include Figure 2 The multiple layers of shelves 4 arranged in a vertical direction for receiving the hopper are shown, and a weighing mechanism 2 for counting the material in the hopper is fixedly arranged on the hopper shelf 4. The hopper shelf is mainly used to provide a horizontal weighing surface for the hopper, and the conveying mechanism 3 automatically transfers the hopper 1 to the upper surface of the hopper shelf. When the length and width of the hopper shelf meet the needs of the hopper, its size should not be specifically limited. The edge of the hopper shelf is fixed on a vertical surface such as a wall, and the hopper shelf is parallel to the horizontal plane. In other embodiments, the arrangement of the hopper shelf is not limited to Figure 2 Among them, the circuit principle of the weighing mechanism 2 is as follows: Figure 5 , including a weighing device 21 fixed on each layer of the hopper shelf and a counting module 22 electrically connected to each weighing device, the weighing device is used to weigh the material in the hopper, and send the collected weighing data to the counting module 22, the counting module 22 is used to count and save the data of the quantity and quality of the materials in all hoppers. It should be noted that the counting module can be specifically implemented through existing technologies, as disclosed in the utility model patent application with application number 202310475362.5: "A metering module for measuring the quantity of various medical consumables and a time limit recording module for recording the service life of various medical consumables are embedded in the controller."

[0019] exist Figure 1-2 The horizontal conveying mechanism 32 of some embodiments based on the present invention includes a set of electromagnetically driven rollers on the left and right sides of the bottom surface of the hopper, each having a configuration as follows: Figure 3 As shown in the shape, magnetic protrusions 321A are evenly distributed on the rim of each electromagnetically driven roller, and the recesses between the protrusions have arc-shaped edges. A magnet (with a fixed magnetic pole) is fixedly installed in the protrusion of the rim, and the magnet includes an electromagnet or a permanent magnet.

[0020] exist Figure 1-2 The horizontal transfer mechanism of some embodiments based on the invention has Figure 4The electromagnetic horizontal conveying rail 322 shown includes a rack rail 322A that matches the wheel rim shape of the electromagnetic drive roller, and one or two horizontal arms 322B of equal height for supporting the rack rail. An electromagnetic coil 322C is buried between adjacent raised racks of the rack rail, and the axial direction of the winding of the electromagnetic coil is in the vertical direction. The width of the rack rail is greater than the width of the bottom surface of the hopper.

[0021] based on Figure 3-4 The working principle of the embodiment is as follows: when the rack track is energized, the alternating magnetic poles of the electromagnetic coil in the depression between the racks will attract or repel the fixed magnetic poles on the protrusion of the wheel rim. Due to the torque generated by this attraction / repulsion force, the electromagnetically driven roller rolls forward on the raised smooth edge of the rack of the rack track, and the protrusion of the wheel rim of the electromagnetically driven roller just falls into the depression between the next racks. By adjusting the power and period of the alternating current in the electromagnetic coil, the alternating magnetic field generated on the electromagnetic horizontal transmission rail can always generate a driving torque in the forward direction of the wheel rim, so as to achieve the effect of the electromagnetic field driving the electromagnetically driven roller to roll, that is: the electromagnetically driven roller is electromagnetically coupled with the electromagnetic horizontal transmission rail, and the electromagnetically driven roller is limited based on the shape of the staggered protrusions and depressions on the upper surface of the rack track.

[0022] In some embodiments based on the above embodiments, the lifting mechanism includes any one of a pneumatic lifting mechanism, a cylinder lifting mechanism, and an electric lifting mechanism, and the lifting mechanism includes a movable part and a fixed part, and the end of the horizontal arm is fixedly connected to the movable part of the lifting mechanism. For example, the end of the horizontal arm is fixed to the end of the cylinder, and the cylinder can move up and down in the vertical track of the lifting mechanism.

[0023] In some embodiments based on the above embodiments, the weighing device includes any weighing device implemented by a gravity sensor, a pressure sensor, or an electronic scale.

[0024] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model based on the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
