Description

Technical Field

[0001] The utility model belongs to the technical field of western medicine detection sampling, and particularly relates to a liquid medicine extraction device for western medicine detection. Background Art

[0002] Western medicine, relative to the traditional Chinese medicine of the motherland, refers to the drugs used by western medicine, generally made by chemical synthesis methods or extracted from natural products; including aspirin, penicillin, painkillers, etc. Western medicine is organic chemical drugs, inorganic chemical drugs and biological products. Looking at its instructions, there are chemical names and structural formulas, and the dosage is more accurate than that of traditional Chinese medicine, usually measured in milligrams. Before western medicine flows into the market, it needs to be detected to ensure the safety of the drugs. Usually, before detection, the drugs need to be configured into liquid medicine, and then the liquid medicine is taken out separately, different chemical substances are added, and their reaction conditions are observed. Due to the detection needs, the liquid medicine needs to be extracted multiple times. However, the traditional extraction using tools such as syringes is time-consuming, and multiple extractions make the operation more cumbersome. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a liquid medicine extraction device for western medicine detection, and the technical scheme adopted is as follows:

[0004] A liquid medicine extraction device for western medicine detection includes a medicine barrel. A partition is arranged inside the medicine barrel. One side of the partition is set as a liquid storage area, and the other side is set as a liquid outlet area. A liquid delivery pipe is installed at the bottom of the liquid storage area, and the other end of the liquid delivery pipe passes through the liquid outlet area and exposes outside the medicine barrel. A top support plate is arranged above the liquid storage area. An extension plate that can cover the liquid storage area extends outward from the upper end of the top support plate. A motor that drives the gear to rotate is installed above the extension plate.

[0005] A protective cover is arranged outside the motor and above the extension plate. An opening for the screw rod to pass through is opened inside both the protective cover and the extension plate. The lower end of the screw rod is connected with a lower pressing plate.

[0006] Further, the lower pressing plate has the same size and shape as the inner side of the liquid storage area. After the lower pressing plate descends, the outer side of the lower pressing plate is closely attached to the inner wall of the liquid storage area, thereby pressing the liquid medicine to be discharged from the liquid delivery pipe.

[0007] Further, a controller for controlling the motor is arranged above the protective cover. The controller can be a button type, a knob type or a remote control type.

[0008] Further, a tooth groove meshing with the gear is arranged on one side of the screw rod. The rotation of the gear can drive the screw rod to rise and fall.

[0009] Further, two positioning sleeves are provided on the upper surface of the lower pressing plate, and a guide rod capable of being inserted into the positioning sleeve is respectively provided on one side of the top frame plate and directly above the positioning sleeve.

[0010] Further, an observation window is provided on one side of the medicine barrel and within the liquid storage area, through which the dosage of the liquid medicine added to the liquid storage area can be observed.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model uses a motor as a power source to drive the screw to move. When the screw moves downward, the liquid medicine in the liquid storage area of the medicine barrel can be pressed out through the lower pressing plate. Therefore, during use, the operator only needs to press the motor controller to start the motor to complete the extraction of the liquid medicine, with higher work efficiency; and by changing the starting device of the motor, such as changing it to a knob-type controller, the speed of the motor can be adjusted at this time, so that the dosage and speed of the liquid medicine discharged can be controlled; when changed to a remote control type controller, with the medicine barrel placed below, it is more convenient to use without occupying the desktop space.

[0013] 2. The dosage of the liquid medicine added in the medicine barrel of the utility model is based on the maximum not exceeding two-thirds of the height of the liquid storage area, so as to ensure that when the lower pressing plate presses downward, there is still some air remaining in the liquid storage area. After the liquid medicine is pressed out, the remaining air can flush out the residual liquid medicine in the liquid storage area and the infusion tube, avoiding the residual liquid medicine in the medicine barrel and facilitating subsequent cleaning for reuse.

[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] As attached Figures 1-4 shown.

[0022] Embodiment 1:

[0023] A liquid medicine extraction device for western medicine testing includes a medicine barrel 1 for containing liquid medicine, a partition 2 for dividing the internal space of the medicine barrel 1 is provided inside the medicine barrel 1, one side of the partition 2 is set as a liquid storage area, and the other side is set as a liquid outlet area, an infusion tube 21 is installed at the bottom of the liquid storage area, and the other end of the infusion tube 21 passes through the liquid outlet area and is exposed outside the medicine barrel 1.

[0024] A top frame plate 3 is arranged above the liquid storage area, and an extension plate capable of covering the liquid storage area is extended outward from the upper end of the top frame plate 3. The shield 6 and the motor with the gear 7 are both installed above the extension plate.

[0025] To ensure that the lower pressure plate 4 always remains opposite to the liquid storage area, two positioning sleeves 41 are provided on the upper surface of the lower pressure plate 4, and a guide rod 31 that can be inserted into the positioning sleeve 41 is provided on one side of the top frame plate 3 and directly above the positioning sleeve 41.

[0026] When in use: the controller at the top of the shield 6 can control the motor connected to the gear 7 to rotate, and the motor rotates forward, as shown in the attached Figure 4 The gear 7 rotates clockwise, and by meshing with the tooth groove on one side of the screw 5, drives the screw 5 to move upward. An opening for the screw 5 to pass through is provided inside the shield 6 and the extension plate. The inner diameter of the opening is the same as the outer diameter of the screw 5, so that the screw 5 can remain stable while moving without shaking.

[0027] Since the lower end of the screw rod 5 is movably connected with the lower pressure plate 4, the screw rod 5 moves upward and simultaneously drives the lower pressure plate 4 upward. During the upward movement of the lower pressure plate 4, before the lower pressure plate 4 is separated from the liquid storage area, the positioning sleeve 41 above the lower pressure plate 4 first contacts with the guide rod 31, so that after the lower pressure plate 4 is separated from the liquid storage area, the relative position with the liquid storage area remains unchanged, so that when the lower pressure plate 4 moves downward, the two can contact smoothly again.

[0028] After the lower pressing plate 4 moves upward and leaves the liquid storage area, the state is as shown in the attached Figure 2As shown in the figure, the processed liquid medicine can be added into the liquid storage area through the gap below the lower pressing plate 4. Through the observation window provided on one side of the medicine bucket 1, the dosage of the added liquid medicine can be understood.

[0029] After the liquid medicine filling is completed, the controller above the shield 6 is used to control the reverse rotation of the motor. The gear 7 rotates counterclockwise, the screw rod 5 descends, and the lower pressing plate 4 presses into the liquid storage area. Since the size and shape of the lower pressing plate 4 are the same as those of the liquid storage area, when the lower pressing plate 4 descends, it will push the liquid medicine in the liquid storage area to be discharged through the liquid infusion pipe 21. The dosage and speed of the discharged liquid medicine are determined by the descending speed and height of the lower pressing plate 4.

[0030] Therefore, only by controlling the operation of the motor through the controller, multiple extraction operations of the liquid medicine can be realized.

[0031] Embodiment 2:

[0032] The difference from Embodiment 1 is that the controller of the motor can adopt a knob switch, and the flow rate of the liquid medicine flowing out of the liquid infusion pipe can be controlled in sequence.

[0033] Furthermore, an extension pipe can be connected to the outer end of the liquid infusion pipe, and the pipeline can be directly pulled above the experimental platform to increase the convenience of use.

[0034] Embodiment 3:

[0035] The difference from Embodiments 1 and 2 is that the controller of the motor can adopt a wireless remote control. The remote control and the extension pipe are both placed above the experimental platform, and the medicine bucket is placed below. Without occupying the desktop space, it is more convenient to use.

[0036] The different controllers adopted by the motor in the above Embodiments 1-3 are all prior arts. Their push-button type, knob type, and remote control type are all common methods, and the specific structures, models, and coefficient indexes of all their components are their own technologies. As long as their beneficial effects can be achieved, they can be implemented. Those skilled in the art only need to install and operate according to the attached user manual, and do not require creative labor from those skilled in the art.

[0037] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall all fall within the protection scope of the present utility model.
