Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, and in particular to an oral liquid measuring device with adjustable volume, which can conveniently adjust the volume and thus quickly and accurately measure liquid medicine. Background Art

[0002] Liquid medicine refers to medicine in liquid form made by dispersing drugs in a suitable dispersion medium. It can be taken orally or externally. The dosage of liquid medicine has a great impact on the condition, so the dosage of various liquid medicines needs to be accurate.

[0003] Existing liquid medicines are usually contained in medicine bottles, and when taking them, the liquid medicine needs to be poured from the medicine bottle into the bottle cap or a measuring cup with a scale to drink. The bottle cap generally has a fixed capacity, and the patient can use the bottle cap to measure the prescribed amount of medicine, but when the amount of liquid medicine is not an integer multiple of the bottle cap capacity, it is generally difficult to measure accurately, so more often it is measured with a measuring cup. The measuring cup has scale lines, but when using the measuring cup to measure the dosage, it is difficult to achieve accurate quantification with one pour, and it often takes multiple pours to reach the required dosage, which is inconvenient to use; when pouring the liquid medicine into the measuring cup, it is difficult to control the amount of medicine poured out. When the amount of medicine poured out exceeds the prescribed amount, it will either cause waste of the liquid medicine or there is a risk of contaminating the liquid medicine when it is poured back into the bottle.

[0004] In addition, when using a measuring cup to measure liquid medicine, you need to carefully observe whether the liquid surface is aligned with the target scale. Now a considerable number of patients are older and have difficulty seeing the scale line when placing the measuring cup on the table due to deteriorating eyesight. Once the scale line is not clearly seen, it is easy to cause inaccurate measurement and affect the dosage of the medicine. Taking medicine is a long process that requires repeated measurement of liquid medicine. When using a measuring cup to repeatedly measure liquid medicine, the cumbersome measurement process will affect the patient's compliance with medication and is not conducive to the patient's long-term regular medication. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the technical defects in the prior art that it is difficult to accurately measure liquid medicine in one go when using a measuring cup, and multiple pouring is often required to reach the appropriate dosage.

[0046] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] This embodiment provides a volume-adjustable oral liquid measuring device, such as Figure 1-3 As shown, it includes a medicine cup 1, a movable inner plug 2 and a lifting mechanism 3; wherein the medicine cup 1 includes a cup body 11 and a cup bottom 12, and an adjustment port 121 is opened in the middle of the cup bottom 12; the movable inner plug 2 is arranged inside the cup body 11 so as to be movable up and down, and the outer wall is sealed and connected to the inner wall of the cup body 11; the upper end surface of the movable inner plug 2 and the inner wall of the cup body 11 are enclosed to form a receiving chamber 100 for containing liquid; the lifting mechanism 3 is installed below the cup bottom 12, and has an output end 321 that can move up and down, and the output end 321 passes upward through the adjustment port 121 and is fixedly connected to the lower end surface of the movable inner plug 2; under the action of external force, the output end 321 can drive the movable inner plug 2 to move up and down in the cup body 11 to change the volume of the receiving chamber 100.

[0048] The volume-adjustable oral liquid measuring device of this embodiment drives the movable inner plug 2 to move up and down through the output end 321 of the lifting mechanism 3, so as to change the depth of the medicine cup 1 and change the volume of the containing chamber 100 of the medicine cup 1. When in use, the volume of the containing chamber 100 is first adjusted according to the dosage of the oral liquid to be taken each time, so that it can just accommodate the dosage of the liquid medicine to be taken each time. After the volume of the containing chamber 100 is adjusted, when taking the oral liquid each time, it is only necessary to fill the containing chamber 100 with the oral liquid, and then it can be taken directly, so that it is not necessary to measure the oral liquid in advance when taking it, and the adverse effects of the cumbersome measuring process on the patient's medication are avoided.

[0049] The volume-adjustable oral liquid measuring device of this embodiment, the lifting mechanism 3 includes a driving seat 31 and a lifting rod 32; the driving seat 31 has a cylindrical cavity 30 inside, and is detachably rotatably connected to the medicine cup 1 through a first connecting structure; the lifting rod 32 has an upper end as the output end 321, and a lower end that passes through the adjusting port 121 and extends into the cavity 30; the lifting rod 32 is levitably connected to the driving seat 31 through a second connecting structure, and when the driving seat 31 rotates, the lifting rod 32 can be driven to move up and down through the second connecting structure; the rod body of the lifting rod 32 is also movably connected to the cup bottom 12 through a limiting structure, and when the driving seat 31 rotates and drives the lifting rod 32 to move up and down through the second connecting structure, the limiting structure can limit the lifting rod 32 so that it cannot rotate with the driving seat 31.

[0050] In this embodiment, the medicine cup 1 is a hollow structure, and taking medicine is generally a long process, which makes it inevitable that the medicine cup 1 will be damaged due to improper use (such as falling, collision, etc.) during use; at the same time, the dosage of common oral liquids is not much different from each other, and one medicine cup 1 can generally meet the use needs. However, when the dosage of individual oral liquids taken at one time far exceeds the dosage of common oral liquids, or when the dosage of individual oral liquids taken at one time is far lower than the dosage of common oral liquids, it is often difficult to use one medicine cup 1 to simultaneously meet the measurement requirements of multiple dosages. Therefore, the drive seat 31 and the medicine cup 1 are detachably connected through the first connecting structure, and the medicine cup 1 can be easily disassembled and replaced, so that the medicine cup 1 of the corresponding volume can be replaced according to the dosage of different oral liquids, so that the volume of the oral liquid measuring device can be accurately adjusted within a large range, and the oral liquid can be accurately measured within a large volume range, which improves the scope of application of the oral liquid measuring device and also reduces the use cost of the patient.

[0051] In the capacity-adjustable oral liquid measuring device of this embodiment, the cup bottom 12 is higher than the bottom end of the cup body 11 by a certain height to form an installation space; the first connecting structure includes an annular guide flange 111 formed on the inner wall of the bottom of the cup body 11, and a guide plug 33 arranged at the upper end of the driving seat 31; the guide flange 111 is located below the cup bottom 12, and a first guide groove 336 is formed on the guide plug 33; the guide plug 33 can be installed in the installation space in a pluggable manner, so as to control the guide flange 111 to be inserted into the first guide groove 336, or to be pulled out from the first guide groove 336.

[0052] The capacity-adjustable oral liquid measuring device of this embodiment further comprises a plurality of guide structures arranged around the outer periphery of the top of the driving seat 31, wherein the guide structures comprise a first horizontal plate 331, a first vertical plate 332, a second horizontal plate 333 and a second vertical plate 334; one end of the first horizontal plate 331 is fixedly connected to the top of the driving seat 31, and the other end extends in a direction away from the driving seat 31, and an inclined surface 335 extending obliquely downward is arranged at the end; the upper end of the first vertical plate 332 is fixedly connected to the lower end surface of the first horizontal plate 331 close to the other end, and the lower end extends in a direction away from the first horizontal plate 331; one end of the second horizontal plate 333 is fixedly connected to the first vertical plate 334 The lower end of 332 is fixedly connected, and the other end extends in the direction away from the first vertical plate 332; the upper end of the second vertical plate 334 is fixedly connected to the other end of the second horizontal plate 333, and the lower end extends in the direction away from the second horizontal plate 333; the first horizontal plate 331, the first vertical plate 332, the second horizontal plate 333 and the second vertical plate 334 are surrounded to form the first guide groove 336; under the action of external force, the guide plug 33 can be inserted into the interior of the guide flange 111, so that the inner side edge of the guide flange 111 slides from the inclined surface 335 into the first guide groove 336, and can rotate in the first guide groove 336.

[0053] In this embodiment, the inclined surface 335 on the first transverse plate 331 can make it easier to insert the guide plug 33 into the installation space, thereby completing the installation of the drive seat 31 and the cup body 11; when the drive seat 31 needs to be disassembled from the cup body 11, force can be applied to all the second vertical plates 334 surrounding the periphery at the same time, for example, by holding all the second vertical plates 334 by hand to deform them toward the center of the drive seat 31; the deformation of the second vertical plates 334 will simultaneously drive the second transverse plate 333 and the first vertical plate 332 to deform toward the center of the drive seat 31, and make the end of the first transverse plate 331 close to the inclined surface 335 bend toward the center of the drive seat 31, causing the outer diameter of the guide plug 33 to become smaller, so that the first guide groove 336 can no longer limit the guide flange 111, so that the guide plug 33 can be smoothly pulled out of the installation space.

[0054] The volume-adjustable oral liquid measuring device of this embodiment further includes a shell 34, which is cylindrical and sleeved on the outer periphery of the drive seat 31, and the upper end of the shell 34 is integrally connected with the lower ends of the plurality of second vertical plates 334. In this embodiment, the shell 34 is more convenient for the patient to grasp than the drive seat 31, so that the patient can adjust the volume of the accommodating cavity 100 and assemble the drive seat 31 and the cup body 11 more conveniently and labor-savingly, and the shell 34 can also make the device more stable when placed.

[0055] The capacity-adjustable oral liquid measuring device of this embodiment, the second connecting structure includes a second guide groove 311 and a guide block 323, the second guide groove 311 is spirally shaped and formed on the inner wall of the cavity 30 of the drive seat 31; the guide block 323 is formed on the lower end side wall of the lifting rod 32, and can slide in the second guide groove 311 when the drive seat 31 rotates.

[0056] The capacity-adjustable oral liquid measuring device of this embodiment, further, the limiting structure includes a limiting groove 324 and a limiting protrusion 122; the limiting groove 324 is vertically arranged on the rod body of the lifting rod 32 along the length direction of the lifting rod 32; the limiting protrusion 122 is formed on the inner wall of the adjusting port 121, and is suitable for being embedded in the limiting groove 324 to prevent the lifting rod 32 from rotating relative to the cup bottom 12.

[0057] In this embodiment, when the driving seat 31 is rotated, the limiting protrusion 122 is embedded in the limiting groove 324 to limit the lifting rod 32 so that it cannot rotate with the driving seat 31. Under the rotation of the spiral second guide groove 311, the guide block 323 drives the lifting rod 32 to perform lifting and lowering movements.

[0058] In the oral liquid measuring device with adjustable capacity of this embodiment, the movable inner plug 2 includes a supporting plug 22 and a sealing plug 21; the lower end surface of the supporting plug 22 is fixedly connected to the output end 321; the lower end surface of the sealing plug 21 is fixedly connected to the upper end surface of the supporting plug 22, and the upper end surface and the inner wall of the cup body 11 are enclosed to form the accommodating cavity 100. In this embodiment, the sealing plug 21 can be made of materials such as silicone or rubber, so as to ensure good sealing with the inner wall of the cup body 11; the supporting plug 22 can be made of hard plastic material, so as to support the sealing plug 21 and prevent the sealing plug 21 from twisting or warping when moving.

[0059] In the oral liquid measuring device with adjustable capacity of this embodiment, the cup body 11 is further made of a transparent material, and is provided with scale lines 112 and scale values ​​113, and the scale lines 112 or the scale values ​​113 are raised on the outer surface of the cup body 11. The scale lines 112 and the scale values ​​113 can help the patient to adjust the volume of the containing cavity 100 quickly and conveniently.

[0060] In the oral liquid measuring device with adjustable capacity of this embodiment, different scale values ​​113 have different colors. Different colors are helpful for patients to accurately identify the scale values ​​113, and prevent elderly patients from being unable to accurately see the scale values ​​due to vision deterioration.

[0061] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
