Oral liquid has the advantages of small dosage, fast absorption, stable quality, convenient to carry and take, and easy to store. It has become one of the fastest-growing dosage forms in drug preparations. At present, when patients take liquid medicine in clinical practice, they mostly observe the medicine bottle, divide the liquid medicine visually and roughly estimate the dosage, or pour the liquid medicine into a cup before taking the medicine. In this way, the amount of medicine taken cannot be accurately determined, and the liquid medicine is easy to spill during the pouring process. The operation is cumbersome, which increases the difficulty of taking medicine for patients. When patients take liquid medicine, the uneven dosage will lead to poor treatment effect and affect the recovery speed of patients. There is also a straw placed in the liquid medicine bottle, and the liquid medicine in the liquid medicine bottle is sucked into the measuring cup through the straw through the air bag.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figure 1 to Figure 5 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle. Figure 4 The utility model Figure 2 Cross-sectional view of the CC line, Figure 5 The utility model Figure 4 A partial enlarged view of point D in the middle.

[0027] The utility model provides an oral liquid medicine dosing device, including an upper cover body 101, a lower cover body 102, a measuring cup 103 and a plurality of fixing mechanisms, wherein the fixing mechanisms include two positioning rods, an arc plate 113, a screw 114 and a rotating block 118, and the rotating member includes a rotating block 112 and a connecting shaft 117. The above-mentioned scheme solves the technical problem that the internal thread arranged inside the upper cover body 101 can only be applicable to the liquid medicine bottles 107 of the same caliber, so when installing other liquid medicine bottles 107, it is necessary to replace different upper cover bodies 101, thereby reducing the practicality of the dosing device. It can be understood that the above-mentioned scheme can be used in the scene of fixing the bottle mouth, and can also be used to solve the problem that the processed parts are inconvenient to clamp.

[0028] According to this specific embodiment, a baffle 104 is provided in both the upper cover body 101 and the lower cover body 102, and a liquid port 105 is provided on the baffle 104, and a filter membrane 106 is provided in the liquid port 105. A liquid medicine bottle 107 is detachably provided above the upper cover body 101, and a sealing ring 108 is provided at the bottle mouth of the liquid medicine bottle 107, and the sealing ring 108 and the corresponding baffle 104 are mutually supported, and a drainage tube 109 is provided below the lower cover body 102, and a rotary piston 110 is provided on the drainage tube 109. The rotary piston 110 has a through hole 111, and the through hole 111 is connected to the rotary piston 110. The upper cover 101 is threadedly connected to the lower cover 102 and is located above the lower cover 102. The drainage tube 109 is detachably connected to the measuring cup 103 and is located in the measuring cup 103. By inverting the liquid medicine bottle 107 in the upper cover 101, the positions of the liquid ports 105 of the two baffles 104 are staggered, and the liquid medicine in the liquid medicine bottle 107 will not flow into the upper cover 101. The upper cover 101 is rotated to align the two liquid ports 105, thereby forming a through cavity inside the upper cover 101 and the lower cover 102, and the liquid medicine in the liquid medicine bottle 107 enters the drainage tube 109 through the through cavity, and the rotary piston 110 is rotated to make the through hole 111 on the rotary piston 110 communicate with the through cavity, and the liquid medicine flows into the measuring cup 103 along the drainage tube 109. Since the measuring cup 103 is provided with a scale, medical staff or patients can accurately Measure the amount of liquid medicine to be taken orally; when the liquid medicine flows to the amount that is about to be taken, rotate the rotary piston 110 so that part of the through hole 111 on the rotary piston 110 is connected to the above-mentioned through cavity, thereby slowing down the flow rate of the liquid medicine, avoiding a large amount of liquid medicine from entering the measuring cup 103, causing unnecessary waste of liquid medicine, and at the same time avoiding the liquid medicine in the liquid medicine bottle 107 from being contaminated; the filter membrane 106 arranged in the liquid port 105 can play a certain filtering role on the liquid medicine, preventing insoluble substances contained in the liquid medicine from entering the patient's mouth.

[0029] Among them, a rotating member is provided at one end of the screw 114, a first thread groove 115 is provided on the inner diameter of the arc plate 113, a plurality of second thread grooves 116 are provided on the outer side of the upper cover body 101, and positioning grooves are provided on both sides of the second thread groove 116.

The arc plate 113 is fixedly connected to the rotating member and is located at one end of the rotating member, and the arc plate 113 is also located in the upper cover body 101. The arc plate 113 is also threadedly connected to the medicine liquid bottle 107 and is located on the outer side of the bottle mouth of the medicine liquid bottle 107. The screw 114 is connected to the upper cover body 1 01 is threadedly connected and is located in the corresponding second thread groove 116. The positioning rod can make the arc plate 113 move horizontally. The first thread groove 115 set on the arc plate 113 can be matched with the thread on the bottle mouth of the medicine bottle 107, so as to facilitate the fixation of the medicine bottle 107. The screw 114 can facilitate the adjustment of the distance of the arc plate 113, so as to clamp the medicine bottles 107 of different calibers. It should be noted that when installing the medicine bottle 107, it is necessary to use the sealing ring 108 that is compatible with the caliber of the installed medicine bottle 107. The sealing ring 108 can prevent the medicine in the medicine bottle 107 from flowing out. A plurality of the arc plates 113 can be combined to form a ring shape, so as to fix the medicine bottle 107.

[0030] Secondly, the rotating block 118 is fixedly connected to the screw rod 114 and is located at the other end of the screw rod 114 . The rotating block 118 can be used to easily rotate the screw rod 114 .

[0031] Again, the rotating block 112 is fixedly connected to the connecting shaft 117 and is located at one end of the connecting shaft 117. The rotating block 112 is rotatably connected to the screw rod 114 and is located at one end of the screw rod 114. The arc plate 113 is fixedly connected to the connecting shaft 117 and is located at the other end of the connecting shaft 117, and the connecting shaft 117 passes through the screw rod 114. Through the cooperation between the rotating block 112 and the connecting shaft 117, the screw rod 114 can be rotated without driving the arc plate 113 to rotate, thereby causing the arc plate 113 to move horizontally.

[0032] When the utility model is used to fix the liquid medicine bottle 107, the screw 114 is rotated by adjusting the plurality of fixing mechanisms, so that the arc plate 113 moves toward the inner side of the upper cover body 101, and then the sealing ring 108 adapted to the liquid medicine bottle 107 is placed in the upper cover body 101, and the bottle mouth of the liquid medicine bottle 107 is placed between the plurality of arc plates 113, and the screw 114 is rotated in the opposite direction at this time, so that the screw 114 pushes the arc plate 113 to close the liquid medicine bottle 107. 07, and finally rotate the medicine liquid bottle 107 to make the medicine liquid bottle 107 threadedly connected with the plurality of arc plates 113, thereby improving the sealing between the sealing ring 108 and the medicine liquid bottle 107. In this way, the technical problem that the internal thread arranged inside the upper cover body 101 can only be used for the medicine liquid bottles 107 of the same caliber and thus when installing other medicine liquid bottles 107, it is necessary to replace different upper cover bodies 101, thereby reducing the practicality of the drug dispenser is solved.
