Abstract
Description
Technical Field
[0001] The utility model relates to the field of liquid transmembrane pressurization, in particular to a tool for facilitating liquid transmembrane pressurization. Background Art
[0002] Inductively coupled plasma mass spectrometers (ICP-MS) are often used in heavy metal testing for soil and agricultural products. This type of instrument is extremely precise and sensitive, so the aperture of the nebulizer at the sample inlet is particularly small. To prevent clogging of the nebulizer after injection, the sample is typically digested with acid to a fixed volume before being transferred to a syringe with a filter membrane and filtered before being tested on the instrument. Since most samples, especially soil samples, still contain some difficult-to-digest impurities or suspended matter after digestion, the filtration process is particularly prone to clogging the membrane, causing significant resistance. Furthermore, the large amount of filtrate required for each sample to be tested on the instrument makes relying solely on fingers and palms to push the plunger for filtration extremely laborious, time-consuming, and labor-intensive, and prolonged operation can easily cause injury to the hands.
[0003] Therefore, a tool is proposed to facilitate the pressurization of liquid through the membrane. It is a manual device that uses the lever principle to pressurize the syringe, thereby avoiding directly pushing the plunger rod with the palm and fingers, saving labor intensity and time, and continuously improving detection efficiency. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a tool that facilitates liquid to pass through the membrane and pressurize, so as to solve the current technical problems that most samples, especially soil samples, still have some impurities or suspended matter that are difficult to digest after digestion, which are particularly easy to clog the filter membrane during the filtration process and cause great resistance. In addition, a lot of filtrate is required for each sample to be put on the machine. It is very laborious and time-consuming to rely solely on fingers and palms to push the plunger rod for filtration, the workload is particularly large, and long-term operation is likely to cause certain injuries to the hands.

[0014] 1. The utility model combines a movable connection mechanism, a pressure plate and a handle block, and can utilize the movable connection mechanism to connect between the first rod body and the second rod body.

[0019] The present invention is further described below with reference to the accompanying drawings and embodiments:
[0020] Example 1: A tool for facilitating liquid pressure transfer through a membrane, see Figures 1 to 2, comprises a first rod body 1 and a second rod body 203, which are connected by a movable connection mechanism; a pressure plate 2 is fixed on one side of the first rod body 1; a fixed shell 204 is fixed on one side of the second rod body 203, and handle blocks 211 are provided at both front and rear ends of one side of the fixed shell 204, and an adjustment component for adjusting the spacing is provided at one end of the handle block 211 located in the fixed shell 204. First, the two handle blocks 211 are respectively clamped at the bottom of the two handles of the syringe, and then the first grip 201 and the second grip 207 are squeezed by hand. The first grip 201 and the second grip 207 will drive the first rod body 1 to move downward and the second rod body 203 to move upward through the rotating shaft 202, thereby driving the two handle blocks 211 to move upward and the pressure plate 2 to move downward. The pressure plate 2 will press the piston handle of the syringe downward, thereby using the lever principle to pressurize the syringe manually, avoiding directly pushing the plunger rod with the palm and fingers, saving labor intensity and time, and continuously improving detection efficiency.
[0021] For details, see Figure 1 , the movable connection mechanism is the rotating shaft 202.
[0022] For further information, see Figure 1 and Figure 2 A square hole 205 is opened on the top of the fixed shell 204, and a movable hole 208 is opened on one side of the fixed shell 204.
[0023] It is worth noting that, see Figure 2 The adjusting component is a movable plate 209 connected to the handle block 211. A threaded hole 210 is provided on the surface of the movable plate 209, and a fixing bolt 206 is connected in the threaded hole 210. When the distance between the two handle blocks 211 needs to be adjusted, the fixing bolt 206 can be unscrewed from the threaded hole 210 on the surface of the movable plate 209, thereby adjusting the position distance between the two handle blocks 211. After the adjustment is completed, the fixing bolt 206 is passed through the square hole 205 on the top of the fixed shell 204 and threadedly connected to the threaded hole 210 on the surface of the movable plate 209 to limit the movable plate 209 and the handle block 211, thereby clamping syringe handles of different sizes, thereby improving the adjustability of the tool and enabling the tool to be used for syringes of different sizes.
[0024] It is worth noting that see Figure 1 and Figure 2 One end of the movable plate 209 extends into the fixed housing 204 through the movable hole 208 , and the bottom of the fixing bolt 206 passes through the square hole 205 and is threadedly connected to the threaded hole 210 on the surface of the movable plate 209 .
[0025] It is worth mentioning that see Figure 1A first handle 201 and a second handle 207 are fixed to the other side of the first rod body 1 and the second rod body 203 respectively.
[0026] When using a tool that facilitates pressurization of liquid through a membrane, first clamp the two handle blocks 211 at the bottom of the two handles of the syringe respectively, then squeeze the first handle 201 and the second handle 207 with your hands, and the first handle 201 and the second handle 207 will drive the first rod 1 to move downward and the second rod 203 to move upward through the rotating shaft 202, thereby driving the two handle blocks 211 to move upward and the pressure plate 2 to move downward. The pressure plate 2 will press down the piston handle of the syringe, thereby using the lever principle to pressurize the syringe manually, avoiding directly pushing the plunger rod with the palm and fingers. When the distance between the two handle blocks 211 is to be adjusted, the fixing bolt 206 can be unscrewed from the threaded hole 210 on the surface of the movable plate 209, thereby adjusting the position distance between the two handle blocks 211. After the adjustment is completed, the fixing bolt 206 is passed through the square hole 205 on the top of the fixed shell 204 and threadedly connected to the threaded hole 210 on the surface of the movable plate 209 to limit the movable plate 209 and the handle block 211, thereby clamping syringe handles of different sizes, thereby improving the adjustability of the tool and enabling the tool to be used for syringes of different sizes.
