Its main task is to continuously provide more effective drugs and improve drug quality, ensure drug safety, and enable patients to treat or cure diseases in a way that minimizes harm and maximizes benefits. At present, dispensing devices are used in the process of preparing liquid medicines.

[0003] For example, the utility model with application number CN201921571888.9 discloses a liquid medicine quantitative extraction device for pharmaceutical dispensing. The utility model uses an air bag to cooperate with the device base to slowly fill the liquid medicine into the measuring cup, and can directly extract a certain amount of liquid medicine in this way, which is highly practical. However, in the process of extracting the liquid medicine, the nurse needs to constantly confirm the scale mark on the measuring cup, and long-term operation is prone to fatigue.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a dispensing device capable of quantitative extraction is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3 As shown, a dispensing device capable of quantitative extraction comprises a dispensing bottle 1 and a floating plate 17, a bearing 2 is arranged at the opening of the top of the dispensing bottle 1, and a bearing 2 3 is arranged at the opening of the bottom of the dispensing bottle 1, an extraction cylinder 4 is arranged in the bearing 2, and a needle 6 is connected to the bottom end of the extraction cylinder 4, the bearing 2 and the bearing 2 3 are arranged coaxially, the needle 6 runs through the middle of the bearing 2 3, the extraction cylinder 4, the needle 6 and the hose 8 are connected to each other, and a liquid inlet unit is installed on the needle 6 The other end of the needle 6 is connected to the valve 7, and a hose 8 is connected, and a counterweight 9 is sleeved on the outer lower part of the hose 8, a liquid outlet pipe 10 is installed on the outer lower part of the extraction cylinder 4, and a liquid outlet check valve 11 is installed on the liquid outlet pipe 10, a floating plate 17 is sleeved on the outside of the extraction cylinder 4, a distance sensor 16 is installed on the inner top of the dispensing bottle 1, and an alarm 18 is installed on the outside of the dispensing bottle 1, the floating plate 17 is a circular ring structure, and a bottle cap 19 is installed on the bottom right side of the dispensing bottle 1.

[0022] The specific operation is as follows: the buoyancy provided by the medicine solution enables the float plate 17 to float. When the medicine bottle 1 is placed vertically, the float plate 17 is in a horizontal state. Since the signal output end of the distance sensor 16 is connected to the signal input end of the controller, the distance between it and the float plate 17 is sensed by the distance sensor 16. When the total distance value obtained by the controller reaches the set value, the alarm 18 is controlled to send out an alarm signal to remind the nurse and reduce the error rate of medicine dispensing.

[0023] like Figure 1 and Figure 2 As shown, stirring blades 12 are connected to the lower sides of the outside of the extraction cylinder 4, and a connecting disc 13 is fixed to the upper outside of the extraction cylinder 4, a ring 14 is connected to the outside of the connecting disc 13, and the outer surface of the ring 14 is wrapped with anti-slip patterns 15, and the inside of the extraction cylinder 4 is connected to the piston push rod 5, and the connecting disc 13 accounts for one third of the thickness of the ring 14.

[0024] The specific operation is as follows: the hand-held ring 14 rotates the connecting disc 13 and the extraction tube 4 to allow the liquid medicine to enter the inside of the dispensing bottle 1, and the stirring blades 12 continuously stir the liquid medicine to ensure a uniform mixing effect inside the dispensing bottle 1.

[0025] In summary, when using the quantitatively extractable drug dispensing device, firstly, the hose 8 is extended into the drug liquid container, and the hose 8 is kept immersed in the liquid surface under the gravity of the counterweight 9. At this time, one hand holds the drug dispensing bottle 1, and the other hand pulls the piston push rod 5 upward, which can generate negative pressure inside the extraction cylinder 4, thereby sucking the drug liquid;

[0026] Since the liquid inlet check valve 7 is configured to allow liquid input but prohibit liquid output, and the liquid outlet check valve 11 is configured to allow liquid output but prohibit liquid input, when the piston push rod 5 is pushed, the liquid inside the extraction cylinder 4 is completely transported to the dispensing bottle 1 along the liquid outlet pipe 10;

[0027] When the fixed amount of liquid medicine in the extraction tube 4 is all input into the dispensing bottle 1, the hose 8 is extended into another liquid medicine container, and the above extraction operation is repeated to allow another liquid medicine to slowly enter the dispensing bottle 1. At this time, the buoyancy provided by the liquid medicine enables the float 17 to float, so that when the dispensing bottle 1 is placed vertically, the float 17 is kept in a horizontal state. Since the signal output end of the distance sensor 16 is connected to the signal input end of the controller, the distance between it and the float 17 is sensed by the distance sensor 16, and the total distance value is sent to the controller. When the total distance value obtained by the controller reaches the set value, the alarm 18 is controlled to send an alarm signal to remind the nurse to release the piston push rod 5 in time to achieve the effect of quantitative extraction, thereby reducing the error rate of dispensing.

[0028] At this time, the anti-slip pattern 15 is used to increase the friction between the hand and the ring 14. By holding the ring 14, the connecting disc 13 and the extraction tube 4 are rotated, so that the stirring blades 12 continuously stir the two liquid medicines to ensure a uniform mixing effect inside the dispensing bottle 1. When the dispensing is completed, the bottle cap 19 is opened to facilitate the discharge of the liquid medicine.

[0029] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
