Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material weighing, and in particular to a device for quantitatively taking Chinese medicinal materials. Background Art

[0002] At present, in traditional Chinese medicine pharmacies, when staff pick up Chinese medicinal materials, they usually use a balance scale and an ordinary electronic scale to weigh multiple Chinese medicinal materials separately, then divide them into multiple small portions of equal weight, and then mix the divided medicinal materials of different types together, and finally package them. Among them, the weighing process of prescriptions containing multiple Chinese medicinal materials requires staff to go back and forth between the Chinese medicine cabinet and the counter many times to weigh each Chinese medicinal material separately, which significantly consumes the physical energy of the staff, prolongs the time of picking up medicines, limits the efficiency of picking up medicines, and causes patients to wait longer for medicines.

[0003] In addition, the use of a balance scale requires the person who takes the medicine to measure with a weight, which is inefficient and has large errors. Although the quantitative measurement of medicine using an electronic scale is more accurate and easier to use, the electronic scale is not easy to move, so it is fixed on the counter for use.

[0004] In order to reduce the manual labor intensity in the process of quantitative drug collection of Chinese medicine prescriptions, improve the accuracy of drug collection and the efficiency of quantitative drug collection, relevant patents have provided solutions. For example, the Chinese patent application number CN201210268543.2 discloses an automatic processing system for Chinese medicine prescriptions. Although the system is convenient for realizing the automatic processing of Chinese medicine prescriptions, it has high investment and at least high requirements for the pharmacy environment and supporting facilities. It is used to replace the existing facilities in use, which is easy to significantly affect the normal operation of the pharmacy. Therefore, it is not suitable for the majority of small and medium-sized Chinese medicine pharmacies, as well as Chinese medicine pharmacies that are already in operation.

[0005] Therefore, it is very necessary to provide a quantitative drug taking device for Chinese medicinal materials which has low cost, good applicability and is conducive to improving drug taking efficiency. Summary of the invention

[0006] The purpose of the present invention includes providing a Chinese medicinal material quantitative medicine dispensing device which has low cost, good applicability, is easy to move, and can be easily and reliably fixed on a drawn medicine cabinet drawer to achieve high-precision quantitative medicine dispensing.

[0007] In order to achieve the above object, the present invention has the following technical solutions:

[0009] Preferably, the relative rotation angle between the vertical connecting rod and the connecting assembly is less than 20°.

[0010] Preferably, a stopper is provided under the movable tray for limiting the movable tray from sliding off the tray.

[0011] Preferably, the connecting assembly includes a front clamping rod, a rear clamping rod, two parallel transverse connecting rods rotatably connected between the upper parts of the front clamping rod and the rear clamping rod, a transverse support rod connected to the upper part of the front clamping rod facing the rear clamping rod, and an ear plate connected to the upper part of the rear of the rear clamping rod, and the rear end of the ear plate is rotatably connected to the vertical connecting rod by means of a pin or the like.

[0012] Preferably, the lower end of the rear clamping rod is vertically connected to a base.

[0013] Preferably, a slide groove is provided on the base, and a telescopic foot is slidably connected in the slide groove. The telescopic foot includes a sliding foot, a screw rod vertically connected to one end of the sliding foot, and a nut threaded on the screw rod. The sliding foot is slidably connected to the slide groove.

[0014] Preferably, a foot pad is connected to the bottom of the base.

[0015] Preferably, the mass of the weight bar is greater than or equal to 3 times the mass of the electronic scale.

[0016] Preferably, the heavy rod is a rubber-coated lead rod or a rubber-coated metal tungsten rod.

[0017] Preferably, a strong magnet such as a neodymium magnet is connected to the lower portion of the heavy rod.

[0018] Preferably, the rear clamping rod is made of metal aluminum.

[0019] Preferably, the connection assembly further comprises two box-hanging rods, and the two box-hanging rods are symmetrically connected to the side surfaces of the rear clamping rod through one end thereof.

[0020] Preferably, the box hanging rod is a hard straight rod with a long strip-shaped hole provided thereon.

[0021] Preferably, a temporary storage box for temporarily collecting and accommodating weighed Chinese medicinal materials is detachably connected to the elongated hole, and a hook is connected to one side of the temporary storage box, and the hook is close to the mouth of the temporary storage box.

[0022] Preferably, the device for quantitatively dispensing Chinese medicinal materials further comprises an anti-slip sticker, and the anti-slip sticker is at least connected to the surface of the base facing the front clamping rod.

[0023] Preferably, the device for quantitatively dispensing Chinese medicinal materials further comprises a handle, and the handle is connected to the connecting support plate and the vertical connecting rod.

[0024] Due to the adoption of the above technical solution, the advantages of the present invention are:

[0025] 1. The weight bar included in the present invention and the method of rotatably connecting the connecting assembly with the weighing part can realize automatic leveling of the electronic scale, so the present invention can be placed on the drawer panel for use and still meet the weighing accuracy requirements of Chinese medicinal materials.

[0026] 2. Hold the handle and lift the present invention to the top of the drawer panel, then lower the present invention to the drawer panel and insert it between the front clamping rod and the rear clamping rod, so that the present invention can be quickly and conveniently fixed on the drawer panel.

[0027] 3. The rear clamping rod included in the present invention automatically squeezes the drawer panel under the action of the electronic scale, the vertical connecting rod, the handle, the weight bar, and its own gravity, and anti-slip stickers are connected to the base and the surface of the rear clamping rod facing the front clamping rod, which can further prevent the connection component from shifting relative to the drawer panel, and the fixation is reliable and stable; as the rear clamping rod is lifted, the distance between the rear clamping rod and the front clamping rod is expanded, and the rear clamping rod and the front clamping rod no longer clamp the drawer panel, so the present invention can be easily taken out of the medicine cabinet drawer by only lifting the present invention, which is convenient to take and move.

[0028] 4. In the present invention, a strong magnet is connected to the side of the lower end of the weight bar facing the rear clamping rod, and the rear clamping rod is made of metal aluminum. When the weight bar swings rapidly after adding Chinese medicinal materials in the movable tray, the eddy current generated by the rear clamping rod interacts with the strong magnet when the strong magnet approaches the aluminum rear clamping rod, so that the strong magnet slows down and promotes the weight bar to quickly stop and maintain a vertical state, thereby achieving rapid and stable weighing state of the electronic scale included in the present invention.

[0029] 5. When the present invention is used for quantitatively dispensing multiple Chinese medicinal materials, the staff only needs to go back and forth between the counter and the Chinese medicine cabinet once to quantitatively weigh multiple Chinese medicinal materials. The quantitative dispensing process does not require the staff to go back and forth to weigh each medicine as in the existing operation. The number of round trips for quantitative dispensing operations for prescriptions containing multiple Chinese medicinal materials can be significantly reduced, which significantly saves the staff's physical energy and medicine dispensing time, is beneficial to improving the efficiency of medicine dispensing work, and reduces the waiting time for patients to get medicine.

[0030] 6. The present invention has a simple structure and is easy to operate. It is particularly suitable for use in small and medium-sized Chinese medicine clinics or hospitals. It does not require modification or adjustment of existing facilities and equipment, has good applicability and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0046] The specific implementation method is now described as follows:

[0047] Embodiment 1 of a device 100 for quantitatively dispensing Chinese medicinal materials provided by the present invention, see Figure 1 , Figure 2 , Figure 3 , Figure 4, including a handle 3, an anti-slip sticker 20, a connecting component 6 and an electronic scale 1, wherein the electronic scale 1 includes a scale body 11, a tray 12 connected to the scale body 11, a movable tray 13 is placed on the tray 12, a block 133 is provided below the movable tray 13, a connecting support plate 2 is connected to the bottom of the scale body 11, a vertical connecting rod 4 is vertically connected to the bottom of the connecting support plate 2, a heavy rod 5 is connected to the lower end of the vertical connecting rod 4, a strong magnet 51 is connected to the lower part of the heavy rod 5, and the axis of the heavy rod 5 coincides with the axis of the vertical connecting rod 4.

[0048] The connecting assembly 6 includes a front clamping rod 64, a rear clamping rod 65, two parallel transverse connecting rods 61 rotatably connected between the upper parts of the front clamping rod 64 and the rear clamping rod 65, a transverse support rod 62 connected to the upper part of the front clamping rod 64 facing the rear clamping rod 65, and an ear plate 63 connected to the upper part of the rear of the rear clamping rod 65, wherein the rear end of the ear plate 63 is connected to the vertical connecting rod 4 through a pin shaft 10; the lower end of the rear clamping rod 65 is vertically connected to a base 7, a slide groove 71 is provided on the base 7, and a telescopic foot 8 is slidably connected in the slide groove 71, and the telescopic foot 8 includes a sliding foot 83, a screw rod 81 vertically connected to one end of the sliding foot 83, and a nut 82 threaded on the screw rod 81, the sliding foot 83 is slidably connected to the slide groove 71, and a foot pad 9 is connected to the bottom of the base 7.

[0049] The handle 3 is connected to the connecting support plate 2 and the vertical connecting rod 4 .

[0050] The anti-slip sticker 20 is bonded to the surface of the base 7 and the rear clamping rod 65 facing the front clamping rod 64 .

[0051] In this embodiment, the relative rotation angle between the vertical connecting rod 4 and the rear clamping rod 65 is 15°; the weight rod is a rubber-coated metal tungsten rod; the rear clamping rod 65 is made of metal aluminum; the anti-slip sticker 20 is a rubber sheet with adhesive coated on one side; the mass of the weight rod 5 is equal to the mass of the electronic scale 1, plus the maximum weighing mass of the electronic scale 1, plus the mass of the connecting support plate 2, plus the mass of the vertical connecting rod 4, and twice the total mass of the handle 3, or the mass of the weight rod 5 is equal to 3 times the mass of the electronic scale 1.

[0052] Embodiment 2 of a device 100 for quantitatively dispensing Chinese medicinal materials provided by the present invention, see Figure 5 , Figure 6 , Figure 7On the basis of the Chinese medicinal material quantitative medicine dispensing device 100 described in the above-mentioned embodiment 1, two box hanging rods 66 are symmetrically connected to the upper part of the side of the rear clamping rod 65, and the box hanging rod 66 is a hard straight rod with a long strip hole on it. A temporary storage box 30 is hung on the long strip hole, and a hook 31 is connected to one side of the temporary storage box 30, and the hook 31 is close to the mouth 32 of the temporary storage box 30.

[0053] In this embodiment, the hard straight rod is made of aluminum alloy material; the temporary storage box 30 is made of polypropylene plastic.

[0054] The connecting assembly 6 provided by the present invention realizes the principle of convenient and stable fixing on the drawer panel 210, see Fig. 9 , Fig.10 :

[0055] The handle 3 is held to lift the present invention to the top of the drawer panel 210 , and then the present invention is lowered to the drawer panel 210 and inserted between the front clamping rod 64 and the rear clamping rod 65 included in the connecting assembly 6 , so that the present invention can be quickly and conveniently fixed on the drawer panel 210 .

[0056] When the cross brace 62 falls on the upper end of the drawer panel 210, the drawer panel 210 blocks the cross brace 62 from continuing to fall. However, the rear clamping rod 65 continues to fall under the action of the electronic scale 1, the vertical connecting rod 4, the handle 3, the heavy rod 5, and its own gravity, so that the parallelogram structure formed by the two cross connecting rods 61 and the upper parts of the front clamping rod 64 and the rear clamping rod 65 is deformed, and the distance between the front clamping rod 64 and the rear clamping rod 65 is reduced until the front clamping rod 64 and the rear clamping rod 65 are clamped on the front and rear surfaces of the drawer panel 210 respectively; further, since the anti-slip stickers 20 are connected to the surfaces of the base 7 and the rear clamping rod 65 facing the front clamping rod 64, they can further prevent the connection component 6 from shifting relative to the drawer panel 210, thereby achieving stable fixation of the connection component 6 on the drawer panel 210, see Figure 2 , Figure 6 .

[0057] The principle of the present invention to prevent the movable tray 13 from being excessively tilted is as follows:

[0058] The present invention can be fixed on the drawer panel 210 of the medicine cabinet drawer 200 along with the connecting component 6. Generally, as the medicine cabinet drawer 200 is pulled out, the drawer panel 210 tilts forward (the more it is pulled out, the more obvious the tilt is). At this time, the front clamping rod 64 and the rear clamping rod 65 fixedly connected to the drawer panel 210 will also tilt forward. However, since the vertical connecting rod 4 is rotatably connected to the ear plate 63, and the upper end of the vertical connecting rod 4 is vertically connected to the bottom of the electronic scale 1 through the connecting support plate 2, and the lower end is connected to a heavy rod 5 (the axis line of the heavy rod 5 coincides with the axis line of the vertical connecting rod 4, and the mass is much greater than the mass of the vertical connecting rod 4 connected to its upper end plus the mass of the electronic scale 1 and other components), the heavy rod 5 always tends to maintain a vertical state under the action of gravity. Therefore, the forward tilting state of the drawer panel 210 is difficult to be transmitted to the electronic scale 1, thereby avoiding excessive tilting of the movable tray 13. Furthermore, since a strong magnet is connected to the side of the lower end of the heavy rod 5 facing the rear clamp rod 65, and the rear clamp rod 65 is made of metal aluminum, when the heavy rod 5 swings rapidly after the Chinese medicinal materials are added to the movable tray 13, the strong magnet 51 will quickly approach and move away from the aluminum rear clamp rod 65. The eddy current generated during the approaching process interacts with the strong magnet 51, causing the strong magnet 51 to decelerate and promote the heavy rod 5 to quickly stop and maintain a vertical state, further promoting the movable tray 13 to quickly maintain a nearly horizontal state, thereby achieving a weighing quantitative accuracy similar to the use state of placing an electronic scale on a platform, see Fig.10 , Fig.11 .

[0059] The method of using the present invention to move to the medicine cabinet drawer 200 to weigh Chinese medicinal materials:

[0060] S1, holding the handle 3, move the present invention to the top of the target medicine cabinet drawer 200, and fix it on the drawer panel 210;

[0061] S2, add the Chinese medicinal materials in the target medicine cabinet drawer 200 into the movable tray 13, until the value displayed on the electronic scale 1 is stably equal to the total weight of the medicine recorded in the prescription;

[0062] S3, lift the movable tray 13, pour the weighed Chinese medicinal materials into the temporary storage box 30, and then put the movable tray 13 back on the tray 12;

[0063] S4, repeat S1 to S3 according to the prescription and continue to weigh the next Chinese medicinal material until all the Chinese medicinal materials recorded in the prescription are weighed into the present invention;

[0064] S5. Bring the present invention to the counter, and mix the various Chinese medicinal materials weighed out from the temporary storage box 30 in a conventional manner.

[0065] The method of unfolding the base 7 of the present invention is as follows:

[0066] S1, loosen the nut 82;

[0067] S2, holding the handle 3, lift or tilt the present invention until the support foot 831 leaves the table;

[0068] S3, push the nut 82 to the right with your fingers until it reaches the end, and then tighten the nut 82. The base 7 can be folded and reduced by following the above steps in reverse.

[0069] After the base 7 of the present invention is unfolded, it can be placed on a counter more stably for weighing.

[0070] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
