Description

Technical Field

[0001] The utility model relates to the field of medicine dispensing and injection equipment, in particular to a solvent pre-dissolution transfer mechanism. Background Technique

[0002] Intravenous infusion is one of the most common ways to treat patients in medical institutions at all levels in China; the number of hospitals adopting intravenous drug dispensing centers has increased rapidly, aiming to solve the relatively high occupational risk of medical and health workers who have been dispensing a large number of harmful drugs for a long time. In the realization of medicine dispensing automation, first, the liquid medicine in the medicine bottle needs to be shaken evenly, and then the solvent bag is filled with the liquid medicine. Before shaking the liquid medicine in the medicine bottle evenly, the medicine bottle also needs to be filled with the solvent, and the filling amount is controlled by a flow meter or time. Therefore, it is difficult to accurately control the filling accuracy, and it is difficult to meet the requirements for medicines with high preparation accuracy of the liquid medicine. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a solvent pre-dissolution transfer mechanism, which is provided with a buffer table with a weight sensor, and can weigh the liquid medicine between shaking and filling. On the one hand, it can buffer the medicine bottle after shaking, and on the other hand, it can significantly improve the accuracy of liquid medicine filling.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a solvent pre-dissolution transfer mechanism, including a handling component, a buffer table and a liquid supply table;

[0005] The handling component is used to shake the medicine bottle evenly and transport it to the buffer table, and transport the medicine bottle on the buffer table to the liquid supply table;

[0006] The buffer table is provided with a weight sensor for weighing the medicine bottle, and the liquid supply table is provided with a needle inserted into the medicine bottle and used for external transportation.

[0007] In this solution, the medicine bottle is first at the waiting material station. The handling component first shakes it evenly and transports it to the buffer table for waiting to be transported to the liquid supply table. When the medicine bottle is on the buffer table, because the buffer table is provided with a weight sensor, the medicine bottle after shaking can be weighed, so as to accurately control the liquid weight in the medicine bottle and provide preparation for subsequent filling.

[0008] Preferably, two groups of handling components are provided. One group of handling components transports the medicine bottle to the buffer table, and the other group of handling components transports the medicine bottle on the buffer table to the liquid supply table. The two groups of handling components can cooperate with each other to significantly improve the handling efficiency.

[0009] Preferably, the handling component includes a robotic arm, a mounting seat and a fixture;

[0010] A flipping motor is provided at the end of the robotic arm, and the mounting seat is provided at the output end of the flipping motor, and the fixture is provided on the mounting seat.

[0011] The fixture is used to clamp the medicine bottle, and the robotic arm is used to shake it. The medicine bottle can be flipped by the flipping motor to adapt to the requirements of different working station angles at the buffer table, liquid supply table, etc.

[0012] Preferably, the fixture includes a linkage structure and a plurality of clamping structures;

[0013] Each of the clamping structures synchronously clamps and releases through the linkage structure.

[0014] By simultaneously controlling multiple clamping structures through the linkage structure, the clamping efficiency can be significantly improved.

[0015] Preferably, the clamping structure includes a driven jaw and a driving jaw that are distributed relatively. The rear ends of the driven jaw and the driving jaw are respectively connected to the mounting seat through a rotating shaft. Arc-shaped racks that mesh with each other are respectively provided at the rear ends of the driven jaw and the driving jaw. A swing arm is provided at the rear end of the driving jaw, and the swing arm is linked with the linkage structure.

[0016] The driven jaw and the driving jaw are matched through the mutually meshing arc-shaped racks. When the linkage structure drives the driving jaw to move, the driven jaw will also move synchronously, thereby achieving the effects of closing and opening.

[0017] Preferably, the linkage structure includes a linkage plate, an eccentric wheel and a torsion spring. The linkage plate is slidably matched with the mounting seat. The linkage plate is provided with a pushing side edge and a stress side edge. The pushing side edge and the torsion spring are respectively located on both sides of the swing arm. The torsion spring is provided on the mounting seat. The torsion spring pushes the swing arm to swing towards the side of the pushing side edge. A clamping motor is provided on the mounting seat, and the eccentric wheel is provided at the output end of the clamping motor. The wheel surface of the eccentric wheel abuts against the stress side edge, and the eccentric wheel pushes the swing arm to swing towards the side of the torsion spring;

[0018] An upper limit plate is provided above the driven jaw and the driving jaw, and the upper limit plate is fixed to the mounting seat.

[0019] The torsion spring and the eccentric wheel are located on both sides of the swing arm. Therefore, when the eccentric wheel pushes the swing arm, the torsion force of the torsion spring will be overcome. When the eccentric wheel does not push the swing arm, the torsion spring will push the swing arm to swing towards the side of the eccentric wheel. Therefore, when the eccentric wheel rotates, with the cooperation of the torsion spring, the swing arm is always in contact with the eccentric wheel. Therefore, the swing arm will swing along with the eccentric wheel, that is, drive the active jaw and the driven jaw to perform the actions of closing and opening.

[0020] Preferably, the buffer table includes a base and a positioning fixture, and the weight sensor is arranged between the base and the positioning fixture.

[0021] The positioning fixture can position the medicine bottle when it is placed, so that the medicine bottle can be stably placed on the buffer table.

[0022] Preferably, the needle is provided with a catheter, and the catheter bypasses the peristaltic pump. In this way, the peristaltic pump can be used to transport the liquid medicine in the medicine bottle out for perfusion.

[0023] Preferably, the needle is fixed upward on the liquid supply table, and the peristaltic pump is located inside the liquid supply table. The upwardly arranged needle can better extract all the liquid medicine inside the medicine bottle, so as to use the peristaltic pump to transport it out for perfusion.

[0024] The beneficial effects of the present utility model are as follows:

[0025] The manipulator is used to transfer and shake the liquid medicine, and a buffer table with a weight sensor is provided, which can weigh the liquid medicine between shaking and perfusion. On the one hand, it can buffer the medicine bottle after shaking, and on the other hand, it can significantly improve the accuracy of liquid medicine perfusion. Description of the Drawings
