DETAILED DESCRIPTION

[0027] The drawings in the present application are not strictly drawn according to the actual proportion, and the specific size and quantity of each structure can be determined according to the actual needs. The drawings described in the present application are only structural schematic diagrams.

[0028] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0029] Unless otherwise defined, the technical terms or scientific terms used herein should be understood as the usual meanings understood by those of ordinary skill in the art to which the present application belongs. The "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Include" or "contain" and similar words mean that the elements or objects before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "In", "out", "up", "down", "far", "near", "front", "back" and the like are only used to represent the relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] A vial is a common sterile injection packaging container, which has a simple structure composed of a bottle neck, a rubber cap at the bottle neck, a plastic cap and a glass tube body (according to the ISO 7864 standard, usually 10-20 mm in diameter and about 30-60 mm in length).

[0031] Among the vials used in hospitals on a daily basis, the two specifications of 5 mL and 10 mL are used the most, and the specific reasons are as follows:

[0032] 5 mL: exactly meets the "regular dose" requirements of 0.5 mL-5 mL injection, freeze-dried powder injection, vaccine, biological product, etc. More than 80 % of the single doses of injections in the pharmacopoeia and medical insurance catalog are in this range.

[0033] 10 mL: It is more convenient for drugs that need to be diluted, administered in several times or prepared into a small amount of infusion solution (such as ceftriaxone, vancomycin, etc.). It neither causes waste by opening too large a bottle at one time, nor reduces the number of drug preparation times.

[0034] 20 mL, 30 mL Although also commonly used in the static configuration center batch liquid, the frequency is significantly lower than 5 mL and 10 mL. Less than 2 mL specifications (1 mL and 2 mL) are more common in insulin, vaccines, special high-priced biological agents, and limited use.

[0035] Based on the above, most of the vials are 5 mL specifications, the fixing seat 21 and other components of the application can be designed in size and position for 5 mL vials, so that the device can assist medical staff to complete most of the drug preparation work. As for the adaptation of other specifications of vials on the application, if there is a large demand in actual work, the size of the fixing seat 21 and other components can be adjusted for the corresponding specifications of the vials, which can meet the related use requirements.

[0040] The driving member 5 is connected with the rotating disc 2, and is used for intermittently driving the rotating disc 2 to rotate, so that the rotating disc 2 drives the vial to move below the first clamping member 31 or the second clamping member 41; specifically, the first clamping member 31 or the second clamping member 41 is a pneumatic mechanical clamping jaw, and the first lifting member 33 and the second lifting member 43 are pneumatic telescopic rods.

[0043] As an alternative embodiment, the lower rotating shaft of the rotating table 1 is provided with a signal disc 6, and a plurality of signal teeth corresponding to the slots of the slot wheel 51 are uniformly distributed on the signal disc 6, and each signal tooth is located in the longitudinal plane of each slot of the slot wheel 51; the side of the lower signal disc 6 of the support table 1 is provided with a position sensor 61 for monitoring the signal teeth, and the position sensor 61 is signal connected with a controller, and the two first lifting members 33 and the second lifting member 43, the driving motor 53, the opening motor 321 and the peristaltic pump 422 are all signal connected with the controller; since the rotating table 2, the slot wheel 51 and the signal disc 6 are located on the same rotating shaft, the rotating table 2, the slot wheel 51 and the signal disc 6 are synchronously rotated in the process of rotating the rotating shaft, and because the fixed seat 21 on the rotating table 2, the slot on the slot wheel 51 and the signal tooth on the signal disc 6 are in one-to-one correspondence, the position sensor 61 only needs to monitor the signal tooth, and the rotating positions of the slot of the slot wheel 51 and the fixed seat 21 with the vial can be known in real time, and then the controller can provide a basis for issuing control instructions of each component by acquiring the monitoring information of the position sensor 61.

[0044] As an alternative embodiment, the support table 1 is also provided with a medicine extraction mechanism 7, which has the same structure as the dispensing mechanism 4, the medicine extraction mechanism 7 extracts the prepared liquid medicine in the vial, and the peristaltic pump 422 of the medicine extraction mechanism 7 is signal connected with the controller; the controller is used for controlling the start and stop of the peristaltic pump 422.

[0045] As an alternative embodiment, the peristaltic pump 422 of the medicine injection part 42 is connected with a medicine storage tank 423; the medicine storage tank 423 is used for storing the liquid medicine to be dispensed.

[0046] As an alternative embodiment, the side of the first clamping member 31 is provided with an exhaust mechanism 9, and the exhaust mechanism 9 is used for extracting the waste generated by the opening of the vial.

[0047] As an alternative embodiment, the support table 1 is provided with a dust cover 8, and the two first lifting members 33 and the second lifting member 43 are arranged on the inner wall of the dust cover 8; specifically, the cylinder bodies of the two first lifting members 33 and the second lifting member 43 are fixedly connected to the top of the inner wall of the dust cover 8 through the connecting plates.

[0048] The working principle and use method of the embodiment are as follows:

[0049] This invention provides a fully automatic solution mixing machine. In operation, vials are first mounted on the fixed base 21 of the turntable 2. Then, the drive motor 53 is started to rotate the dial 52, causing the dial 52 to intermittently rotate the grooved wheel 51. The grooved wheel 51, via the rotating shaft of the turntable 2, causes the turntable 2 to rotate intermittently, thus rotating the vials. Since the turntable 2, grooved wheel 51, and signal disk 6 are located on the same rotating shaft, they rotate synchronously during the shaft's rotation. Because the fixed base 21 on the turntable 2, the grooves on the grooved wheel 51, and the signal teeth on the signal disk 6 are in a one-to-one correspondence, the position sensor 61 only needs to monitor the signal teeth to know the real-time rotational position of the grooves on the grooved wheel 51 and the fixed base 21 with the vials. The controller then uses the monitoring information from the position sensor 61 as the basis for issuing control commands to each component in the next operation.

[0050] When the controller determines that the vial has rotated to the bottom of the opening mechanism 3, it first controls the first lifting member 33 to move the first clamping member 31 downward and controls the first clamping member 31 to grip the vial. Then, the first lifting member 33 drives the opening motor 321 to move downward so that the opening knife 322 abuts against the vial. Subsequently, the opening motor 321 is started to drive the opening knife 322 to rotate so that the opening knife 322 drills a hole in the plastic cap of the vial. During the opening process, the exhaust mechanism 9 continues to work to discharge the waste generated during the opening process through the exhaust mechanism 9. After the opening work is completed, the drive motor 53 is started to drive the turntable 2 to continue to rotate.

[0051] When the opening vial is rotated to the lower part of the dispensing mechanism 4, the controller controls the second lifting member 43 to drive the second clamping member 41 to clamp the vial, then another second lifting member 43 inserts the injection needle 421 into the vial, the peristaltic pump 422 injects the required liquid into the vial from the medicine tank 423, and then the injection needle 421 is pulled out. After that, under the action of the second lifting member 43 and the second clamping member 41, the vial with the mixed liquid is moved up and down several times to fully mix the liquid in the bottle. Finally, the rotating disc 2 rotates the vial to the lower part of the medicine extraction mechanism 7, and the operation mode during injection is the same. After the injection needle 421 is inserted into the vial, the peristaltic pump 422 is used to extract the mixed liquid for use; specifically, the extracted liquid can be extracted from different positions according to different use modes. If the extracted liquid is used for drip injection, the output pipe of the peristaltic pump 422 can be directly connected to the drip bottle to extract the mixed liquid into the drip bottle for use. If the extracted liquid is used for intramuscular injection, the output pipe of the peristaltic pump 422 can be connected to a transition container, and the mixed liquid can be extracted and used by using a syringe. For other use modes, the staff can connect the relevant containers to the output pipe of the peristaltic pump 422 according to the actual needs to complete the extraction and use of the liquid. The specific extraction position of the liquid is not strictly limited by the present application.

[0052] The medical liquid dispensing machine innovates the existing liquid dispensing process and fundamentally improves the quality of medical services. The introduction of this fully automatic solution dispensing machine not only greatly reduces the errors in the drug dispensing process and improves the accuracy of the dispensing, but also significantly improves the work efficiency of the hospital and effectively reduces the work burden of the medical staff.
