Technical Field

[0001] The present application relates to a semi-automatic sampling claw structure for freeze-drying medicines, and belongs to the technical field of freeze-drying medicine sampling structures. Background Art

[0002] The drug sampling structure of the freeze-drying machine is mostly used in the field of early process development of new drugs. As the current market demand for new drugs is increasing, it is also very important for the development of new drugs and early testing of drugs. During the whole process of freeze-drying of new drugs, it is necessary to continuously take out the drugs from the drying box at various stages for observation and research, and the quality of the drugs also needs to be strictly protected during this process. The drugs need to be plugged in the drying box before they can be taken out, so as to ensure that the drugs are not contaminated by the outside world. The process involves two actions: plugging and taking out. The current sampling claws can only realize the taking out action, resulting in the need to use different instruments for plugging and taking out, which increases the possibility of drug contamination; therefore, it is particularly important to choose a suitable sampling claw to clamp the drug bottle. Summary of the invention

[0006] The sampling clamping claw and the plug pressing rod are connected to the same push rod via a clamping action connecting rod and a plug pressing action connecting rod respectively;

[0007] The movement of the push rod drives the sampling clamping claw and the plugging rod to synchronously complete the clamping action and the plugging action, thereby achieving synchronous completion of clamping and plugging.

DETAILED DESCRIPTION

[0019] In order to make the present application more clear and understandable, a preferred embodiment is described in detail as follows with reference to the accompanying drawings.

[0020] Example

[0021] This embodiment provides a semi-automatic sampling claw structure for freeze-drying machine medicine, which can realize the pressing of the rubber stopper while taking out the medicine bottle. The sampling claw is made into a structure that integrates clamping and plugging, and can also perform plugging work while clamping. The whole process is completed in the drying box, ensuring the structure and quality properties of the medicine;

[0022] Structure Figure 1 As shown, the medicine bottle 1 is used to hold medicines; the right sampling claw 2 and the left sampling claw 3 are hinged in the middle to form a sampling claw for clamping the medicine bottle 1; the front ends of the right sampling claw 2 and the left sampling claw 3 are working ends for clamping the medicine bottle 1, and the shapes are both set to be arc-shaped to match the outer contour of the medicine bottle 1;

[0023] The plugging wheel 4 is arranged on the sampling clamping claw, and is located just above the medicine bottle 1. It is used to plug the rubber plug 17 while clamping the medicine. The roller can roll on the rubber plug to reduce the friction and lateral thrust on the rubber plug; the sampling claw hinge shaft 5 is a rotating shaft used to connect the right sampling claw 2 and the left sampling claw 3; the plugging wheel 4 is installed on the front end of the plugging rod 6 close to the medicine bottle 1, and the middle part of the plugging rod 6 is hinged to the end of the sampling claw hinge shaft 5, so that the front end of the plugging rod 6 swings up and down to drive the plugging wheel 4 to move up and down for plugging the rubber plug 17. The plugging rod 6 is hinged to the front end of the plugging connecting rod 7 at the rear end away from the medicine bottle. The plugging connecting rod 7 serves as a power input and is used to push the plugging rod 6 to realize the up and down swing of the front end of the plugging rod 6;

[0024] The rear ends of the right sampling claw 2 and the left sampling claw 3 away from the working end are hinged to the sampling claw connecting rod 18, and the rear ends of the plugging connecting rod 7 and the sampling claw connecting rod 18 are hinged to the push rod 8. The push rod 8, the sampling claw connecting rod 18, and the sampling clamping claw form a clamping action component, and the push rod 8, the plugging connecting rod 7, the plugging rod 6, and the compression wheel 4 form a plugging action component. The push rod 8 realizes unified action input, and the clamping action and the plugging action are synchronously integrated.

[0025] Taking the push rod 8 as the dividing line, the rear end of the push rod 8 is the non-sterile area and the front end is the sterile area. The sterile and non-sterile areas need to be separated. The sampling rod sealing shell 9 is used to seal the push rod 8. The sealing push rod 8 slides back and forth in the sampling rod sealing shell 9. A lubricating sleeve 10 is installed between the push rod 8 and the sampling rod sealing shell 9 to facilitate lubrication and support of the push rod 8. The O-ring 13 is used to seal the push rod 8; the sampling rod sealing shell 9 extends forward with a bracket to fix and support the sampling claw hinge shaft 5, which plays the role of supporting the clamping action component and the plugging action component. The forward bracket of the sampling rod sealing shell 9 is provided with a cushion seat 11, which is used to isolate the right sampling claw 2, the left sampling claw 3 and the forward bracket of the sampling rod sealing shell 9 to avoid friction; one end of the compression spring 14 is connected to the push rod 8 and the other end is connected to the sampling rod sealing shell 9. Under the thrust of the compression spring 14, the sampling claw is closed, the plugging rod will be pressed down, and the rubber plug will be pressed on;

[0026] The rear end of the sampling rod sealing shell 9 is connected to the sampling outer rod 15, and the sampling outer rod 15 and the sampling rod sealing shell 9 are welded together to move and fix the entire sampling claw structure; the rear end of the push rod 8 is connected to the drawing wire 16, and the drawing wire 16 is pulled to control the movement of the push rod 8. The drawing wire 16 is set in the inner cavity of the sampling outer rod 15. The drawing wire 16 can extend the operating distance. The drawing wire 16 pulls the push rod 8, drives the sampling claw to open, and takes out the plugged bottle from a specific sampling port.

[0027] The working process of the semi-automatic sampling claw structure provided by the present application is that the compression spring 14 provides rebound force and maintains the thrust of the push rod 8, the sampling claw remains clamped, the compression wheel 4 remains in a low position, the wire drawing 16 is pulled backward, and the push rod 8 is driven to move backward, the sampling claws are separated, and the compression wheel 4 is raised under the drive of the plug pressing rod 6, and the semi-automatic sampling claw structure is moved to the medicine bottle 1 to be clamped, the sampling claw is aligned with the medicine bottle 1, and the compression wheel 4 is aligned with the bottle mouth plug 17, the wire drawing 16 is released, and the push rod 8 is pushed forward under the push of the compression spring 14, and the sampling claw clamps the medicine bottle 1 through the transmission of the clamping action component and the plug pressing action component to realize semi-automatic sampling, and the compression wheel 4 presses the plug 17 to realize the synchronous completion of clamping and plugging.

[0028] The above structure is used as a semi-automatic sampling claw structure for freeze-drying medicines, which can complete the clamping and plugging work inside the drying box, ensuring zero external contamination of the medicines.
