Description

Technical Field

[0001] This utility model relates to the field of separation and sampling technology, specifically a sampling device that facilitates separation. Background Technology

[0002] When sampling a tumor, the tumor sample is not easy to separate from the tumor body, which affects the sampling. In order to facilitate separation and sampling, the existing method usually involves directly inserting a sampling needle into the tumor and extracting the tissue inside the tumor by suction.

[0003] However, the current method of directly puncturing and extracting tumors has several drawbacks: First, direct puncture can only sample soft tissue within the tumor; when the tumor is blocky, it cannot be sampled. Second, the current sampling method is not conducive to tumor separation. Therefore, a sampling device that facilitates separation is provided (see patent number: 202222922449.6). This device includes an operating handle and a sample collection tube installed at the end of the operating handle. A sampling blade is housed within the sample collection tube at the end furthest from the operating handle. A transmission rod is mounted on the sampling blade, which passes sequentially through the sample collection tube and the operating handle and is connected to a sliding rotation mechanism. The sliding rotation mechanism can drive the sampling blade to extend or retract into the sample collection tube via the transmission rod, and can also drive the sampling blade to rotate outside the sample collection tube. This invention achieves fragmented sampling and targeted sampling of tumors, enabling sampling of hard parts of the tumor, facilitating separation of the tumor sample from the tumor, and allowing for continuous sampling.

[0004] However, in existing sampling devices that facilitate separation, the control over the separation of sample solutions after they are separated into upper and lower layers is poor. The upper layer of sample solution is easily exported along with the sample solution. Furthermore, in order to control the export of the upper layer of sample solution, the lower layer of sample solution may not be completely exported. This not only increases consumption but also reduces the utilization rate to some extent.

[0005] To address the aforementioned problems, a sampling device that facilitates separation has emerged. Utility Model Content

[0006] The purpose of this invention is to provide a sampling device that facilitates separation, in order to solve the problems of poor control over separation and high consumption of samples during separation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for easy separation, comprising a separation sampling tube, a first discharge tube at the bottom of the separation sampling tube, a side tube on one side of the first discharge tube, and a linkage frame and a regulating valve movably connected to the end face of the first discharge tube.

[0008] The bottom of the side tube is provided with a glass hose, the bottom of the glass hose is provided with a second discharge pipe, and a rotating shaft is rotatably connected to the top of one end of the second discharge pipe.

[0009] The first discharge pipe is fixedly connected to a support frame on the outside;

[0010] The regulating valve includes a rotating rod, one end of which is equipped with a gear.

[0011] As a further improvement of this utility model: multiple sets of locking teeth that match the gears are evenly arranged at the top of the internal part of the linkage frame, the gears are meshed with the linkage frame through the locking teeth, and one side of one end of the linkage frame is rotatably connected to the side tube through a rotating shaft.

[0012] As a further improvement of this utility model: one end of the support frame is provided with a movable hole, the rotating rod is rotatably connected to the support frame through the movable hole, and a damping pad is provided at the connection end between the rotating rod and the support frame.

[0013] As a further improvement of this utility model: the top and bottom of one end of the first discharge pipe are provided with limiting blocks located at the top and bottom of the linkage frame.

[0014] As a further improvement of this utility model, the side tube, the glass hose, and the second discharge tube are all fixedly connected by flanges.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By generating a rightward pulling force on the linkage frame, the linkage frame moves to the right, and under the action of the rotating shaft, a rightward pulling force is generated on the side tube, causing the side tube to quickly extend into the glass bottle. Then, the valve on the side tube is opened, allowing the sample located in the lower layer on the first discharge tube to be discharged through the side tube, the glass tube, and the second discharge tube at the bottom. This results in more lower layer solution being discharged, while reducing the content of lower layer solution inside the separation sampling tube, thus reducing consumption.

[0017] 2. By turning the regulating valve and driving the rotating rod and gear to rotate, the linkage frame is moved to the right, so that the bottom of the second discharge pipe can be better extended to the glass bottle mouth located below the separation sampling tube. This better extension at this position prevents leakage during the feeding process and ensures the stability of operation. Attached Figure Description

[0025] Among them, a glass hose 201 is provided at the bottom of the side tube 2, a second discharge pipe 202 is provided at the bottom of the glass hose 201, and a rotating shaft 203 is rotatably connected to the top of one end of the second discharge pipe 202.

[0026] Among them, the first discharge pipe 101 is externally fixedly connected to a support frame 102;

[0027] The regulating valve 4 includes a rotating rod 401, and a gear 402 is provided at one end of the rotating rod 401.

[0028] Please see Figures 1 to 3 Multiple sets of teeth that match the gear 402 are evenly arranged at the top of the internal linkage frame 3. The gear 402 is connected to the linkage frame 3 through the teeth. One side of one end of the linkage frame 3 is rotatably connected to the side tube 2 through the rotating shaft 203.

[0029] Please see Figures 1 to 3 One end of the support frame 102 is provided with a movable hole, and the rotating rod 401 is rotatably connected to the support frame 102 through the movable hole. A damping pad is provided at the connection end of the rotating rod 401 and the support frame 102.

[0030] Please see Figures 1 to 3 The top and bottom of one end of the first discharge pipe 101 are provided with limiting blocks located at the top and bottom of the linkage frame 3, which are used to ensure that the linkage frame 3 moves horizontally to the left or right, so that its side has a better operating effect on the rotating shaft 203.

[0031] Please see Figures 1 to 3 The side pipe 2, the glass hose 201, and the second discharge pipe 202 are all fixedly connected by flanges and are mated together using flanges. At the same time, corresponding sealing gaskets are installed inside for sealing the connection.

[0032] The working principle of this utility model is as follows: After the sample is placed inside the separation sampling tube 1, after a period of sedimentation and separation, the upper and lower layers are separated. After separation, if it is necessary to export some of the liquid, the valve on the first discharge pipe 101 can be opened directly to export the material in the lower layer. When the remaining content is very small, the valve on the first discharge pipe 101 is closed, and then the regulating valve 4 is rotated, which drives the rotating rod 401 and the gear 402 to rotate. Since the gear 402 is connected to the linkage frame 3 through the meshing of the teeth, it can generate a rightward pulling force on the linkage frame 3, causing the linkage frame 3 to rotate. While moving to the right, the rotating shaft 203 generates a rightward pulling force on the side tube 2, causing the side tube 2 to shift to the right with the glass tube 201 as the base point. This allows the bottom of the side tube 2 to extend better into the glass bottle below. Then, the valve on the side tube 2 is opened, allowing the sample located in the lower layer on the first discharge tube 101 to be discharged through the side tube 2, the glass tube 201, and the second discharge tube 202 at the bottom. This allows for the discharge of more lower layer sample solution while reducing the amount of lower layer solution inside the separation sampling tube, thereby reducing consumption and improving utilization to some extent.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
