Shaking device for sampling tubes

Abstract

This application relates to a sampling tube shaking device, specifically a shaking device comprising a body, a support tray, and multiple rollers. The support tray is mounted on and extends from the body, and is configured to reciprocate along the horizontal direction of the body. Multiple rollers are evenly arranged along the length of the support tray and are rotatably connected to it. A rolling motor connected to one of the rollers is also mounted on the support tray, and the roller connected to the rolling motor is connected to the other rollers via a pulley assembly. This application, by providing a shaking device that enables automated individual oscillation, individual rolling, or oscillation and rolling movements of the sampling tube, replaces traditional manual rinsing and drug recovery methods. It allows for comprehensive, rapid, and repeatable recovery of drugs from the sampling tube, eliminating the time-consuming nature of manual operation and the resulting fluctuations in recovery efficiency, reducing test variability, and ensuring the accuracy of dosage measurements.

Description

Technical Field

[0001] This application relates to the field of shaking devices, and more particularly to a sampling tube shaking device. Background Technology

[0002] The delivery dose uniformity (DDU) test for inhaled formulations (including inhaled aerosol MDIs and inhaled powder DPIs) is a core bridge connecting product manufacturing quality and clinical medication safety. It not only needs to meet the requirement of "consistent dosage for each batch of products", but also to ensure the stability of each press of the same can of medicine. This is directly related to the characteristics of inhaled formulations, which are "targeted delivery through the respiratory tract and dose precision dependent on the synergistic effect of the device and the formulation".

[0003] The core logic of this test is to collect the drug using a dedicated delivery dose uniformity sampling device (such as an aerosol sampling tube or a powder inhaler sampling tube) by simulating clinical use scenarios (such as inhalation flow rate and triggering method), and then to evaluate the "effective dose actually delivered to the patient's lungs" through precise quantification. Thorough rinsing of the sampling tube and drug recovery are the core steps to ensure the authenticity and reliability of this evaluation result.

[0004] In existing technologies, the rinsing of sampling tubes and drug recovery are mainly achieved through manual operation. This is time-consuming and labor-intensive. In addition, the rinsing force, speed and solvent pouring angle of different operators may vary, which may lead to fluctuations in the recovery efficiency of the same batch of samples (e.g., the recovery efficiency may be 92% for a novice operator and 98% for a skilled operator). This directly affects the accuracy of the dose measurement value and needs to be improved. Utility Model Content

[0005] In view of the above problems, this application is made in order to provide a sampling tube shaking device that overcomes or at least partially solves the above problems.

The tray frame is provided with a swing component, and the swing component is provided with a sliding hole for the eccentric shaft to be inserted into for vertical sliding. When the swing motor drives the eccentric shaft to rotate, the eccentric shaft drives the tray frame to reciprocate along the optical axis through the swing component.

[0008] Optionally, the rolling motor is connected to the end roller and is arranged in parallel with the end roller.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0016] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0017] This embodiment provides a sampling tube shaking device.

[0018] Reference Figures 1-3 The sampling tube shaking device includes a body 1, a support tray 2 set on the body 1, and multiple rollers 3 set on the support tray 2.

[0019] The carrying tray 2 includes a tray body 21 and a tray frame 22 for carrying the tray body 21, and the tray is located outside the body 1.

[0020] At least two pairs of support columns 11 are arranged side by side at the bottom of the body 1. Each pair of support columns 11 is arranged opposite to each other and is connected by a horizontally arranged optical axis 111. The bottom of the tray frame 22 is provided with sliders 221 corresponding to the number of optical axes 111. Multiple sliders 221 are correspondingly arranged on multiple optical axes 111 and are all horizontally slidably connected to them.

[0021] A swing element 12 is provided at one end of the bottom of the tray frame 22, and a sliding hole 121 is provided on the swing element 12 along the vertical direction. A swing motor 13 is provided at the bottom of the machine body 1, located next to the swing element 12. An eccentric shaft 131 is provided on the swing motor 13. The eccentric shaft 131 can be inserted into the sliding hole 121 and slide along its vertical direction. When the swing motor 13 drives the eccentric shaft 131 to rotate, the eccentric shaft 131 drives the tray frame 22 to slide horizontally along the optical axis 111 through the cooperation with the sliding hole 121, thereby driving the entire carrying tray 2 to perform horizontal reciprocating sliding motion along the length direction of the optical axis 111.

[0022] Multiple rollers 3 are evenly arranged along the length of the disc body 21, and both ends of the rollers 3 are rotatably connected to the sides of the disc body 21. A rolling motor 211 is also provided on the disc body 21. The rolling motor 211 is connected to one of the rollers 3 via a coupling, and the roller 3 connected to the rolling motor 211 is connected to the other rollers 3 via a pulley assembly 4 to achieve synchronous rotation drive of all rollers 3. In specific implementation, the rolling motor 211 is preferably configured to be connected to the roller 3 located at the end, and arranged parallel to the roller 3 located at the end, to effectively save space on the disc body 21.

[0023] To meet the rolling motion requirements of sampling tubes with pressure measuring holes or other accessories, at least one pair of adjacent rollers 3 are provided with clearance grooves 31. In specific implementation, since the sampling tubes with pressure measuring holes or other accessories are rarely shaken, it is preferable that the rollers 3 connected to the rolling motor 211 and their adjacent rollers 3 are provided with clearance grooves 31.

[0024] To ensure that the roller 3 generates sufficient friction to rotate the sampling tube, the surface of the roller 3 is covered with a soft rubber material 32. At the same time, to prevent the sampling tube from scratching the surface of the sampling tube due to contact with the inner wall of the disc 21 during the shaking process, foamed silicone 5 is provided on the inner wall of the disc 21.

[0025] When performing the shaking operation, the corresponding sampling tube is first placed on the roller 3, and then the rolling motor 211 and / or the swing motor 13 are controlled to realize the automatic control of the sampling tube to swing alone, roll alone, or swing and roll together, which meets the needs of rinsing the sampling tube and recovering the drug.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
