Description

Technical Field

[0001] The utility model relates to the technical field of dissolution instruments, in particular to a liquid replenishing mechanism for a dissolution instrument. Background Art

[0002] The dissolution apparatus is an indispensable experimental equipment in the fields of drug production and quality inspection. Its main function is to monitor the release process of drugs to help drug manufacturers understand the dissolution mechanism and kinetic process of drugs, and then optimize the formulation and production process. In addition, the dissolution apparatus can also be used as an important tool for drug quality inspection to test whether the release of drug ingredients in drugs complies with national standards and relevant regulations to ensure the quality and safety of drugs.

[0003] However, when the existing dissolution instrument refilling mechanism is used, in order to ensure the accuracy of the measurement result, it is necessary to refill the dissolution cup. However, when refilling the dissolution cup, the staff manually injects the liquid into the dissolution cup using a syringe, which is inconvenient to operate. At the same time, there are multiple dissolution cups in the water bath of the dissolution instrument, and the staff is required to refill the dissolution cups in turn. The operation steps are cumbersome, which increases the work tasks of the staff, and the efficiency of refilling the dissolution cup is relatively slow, which has a certain impact on the accuracy of the measurement result. Therefore, a dissolution instrument refilling mechanism is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a dissolution instrument refilling mechanism. The utility model solves the problem that the existing dissolution instrument refilling mechanism is inconvenient to refill dissolution cups at different positions when in use, by arranging an electric telescopic rod, a refilling head, a liquid tank, a pump body, a motor, a threaded screw, a transmission sleeve, a driving rod and a support plate.

[0005] The technical solution adopted by the utility model to solve the technical problem is a dissolution instrument fluid replenishing mechanism, comprising a dissolution instrument body and a liquid tank, a water bath for heating is fixed to the outer side of the dissolution instrument body by screws, a dissolution cup for dissolving medicine is placed inside the water bath, a motor for driving a threaded screw to rotate is bolted inside the dissolution instrument body, a transmission sleeve connected to a driving rod is threadedly connected to the outer side of the threaded screw, a support plate for fixing an electric telescopic rod is welded to the outer side of the driving rod, a fluid replenishing head for replenishing fluid in the dissolution cup is screwed to one side of the electric telescopic rod, a delivery pipe connected to a pump body is screwed to one side of the fluid replenishing head, and a branch pipe connected to the liquid tank is screwed to the outer side of the pump body.

[0006] By adopting the above technical scheme, when the inside of the dissolution cup needs to be replenished with fluid, the electric telescopic rod in the support plate converts the received electrical energy into mechanical energy, the electric telescopic rod drives the replenishment head to move above the dissolution cup, and the pump body outside the liquid tank works, and then the liquid in the liquid tank is transported to the delivery pipe outside the pump body through the branch pipe, and then the replenishment head at one end of the delivery pipe transports the liquid to the inside of the dissolution cup. After the replenishment of the dissolution cup is completed, the pump body switch on the liquid tank is turned off, and multiple dissolution cups are placed in the water bath. The motor in the main body of the dissolution instrument drives the threaded screw to rotate, and the transmission sleeve outside the threaded screw drives the support plate on the drive rod to move, and the support plate drives the replenishment head on the electric telescopic rod. The delivery pipe on one side of the replenishment head is a corrugated pipe, and the delivery pipe is retracted and extended with the replenishment head, so that the replenishment head moves to above the dissolution cups at different positions, thereby facilitating the replenishment of the dissolution cups at different positions.

[0007] Specifically, a fixing rod is welded inside the main body of the dissolution instrument, and a connecting block connected to the transmission sleeve is slidably connected inside the fixing rod.

[0008] By adopting the above technical solution, when the transmission sleeve moves outside the threaded screw, the connecting block outside the transmission sleeve slides outside the fixed rod, so that the transmission sleeve is limited, which facilitates the lateral movement of the transmission sleeve outside the threaded screw.

[0009] Specifically, a connection groove for moving the driving rod is provided on the surface of the dissolution instrument body.

[0010] By adopting the above technical solution, when the driving rod drives the support plate to move, the driving rod slides in the connecting groove provided on the surface of the dissolution instrument body, thereby improving the stability of the movement of the driving rod.

[0011] Specifically, the power output end of the motor is connected to the power input end of the threaded screw.

[0012] By adopting the above technical solution, when the threaded screw is to be driven to rotate, the motor in the main body of the dissolution instrument converts the received electrical energy into mechanical energy, and the motor drives the threaded screw to rotate.

[0013] Specifically, the input ends of the motor and the electric telescopic rod are both electrically connected to the output end of the external power supply.

[0014] By adopting the above technical solution and connecting to an external power source, the electrical device can work normally.
