Technical Field
[0001] The utility model relates to the technical field of medical examination sampling, in particular to a sampling device for medical examination. Background Art
[0002] Medical testing is an essential component of the medical field. By conducting microbiological, immunological, biochemical, genetic, hematological, biophysical, and cytological tests on human samples, they provide crucial information for the prevention, diagnosis, and treatment of human diseases and the assessment of human health. Sample collection is a critical step in the medical testing process. However, traditional sampling methods for medical testing present several challenges. For example, medical staff must repeatedly use a rubber-tipped dropper for sampling, which is cumbersome, time-consuming, and labor-intensive, and carries a high risk of sample contamination.
[0003] After searching, a Chinese patent with announcement number CN219511880U discloses a medical test sampler, including a sampling tube, a fixed plate, and a piston body. Although the above patent does not require medical staff to repeatedly take a rubber-tipped dropper to take samples, thereby saving time and effort, the sampler needs to be cleaned and disinfected after a single sampling, which is not only time-consuming and labor-intensive, but also difficult to ensure the disinfection effect. Because the sampler needs to be cleaned and disinfected, it is necessary to wait for a certain period of time after each sampling, which affects the efficiency of the entire inspection process. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that the sampler needs to be cleaned and disinfected after a single sampling, which is not only time-consuming and labor-intensive, but also reduces the sampling efficiency of medical examinations, and to propose a sampling device for medical examinations.

The movement of the pressing plate 103 and the piston 102 forms an air pressure difference, thereby realizing the suction and discharge of the liquid, and the outer sleeve of the pressing rod 101 is provided with a spring 104, one end of the spring 104 is fixedly connected to the top of the piston 102 by a bolt, and the other end of the spring 104 is fixedly connected to the top of the sampler 1 by a bolt, the bottom of the sampler 1 is threadedly connected with a connecting sleeve 106, and one end of the connecting sleeve 106 is provided with a connecting head 107, and the outer surface of one end of the connecting head 107 is integrally formed with a convex ring 108;
[0026] One end of the connecting sleeve 106 is clamped with the sampling hose 3, and the sampling hose 3 includes a butt joint 301 and a sampling tube 302. The outer side of the butt joint 301 is integrally formed with an annular groove 303, and the inner side of the annular groove 303 is clamped with a convex ring 108. The placement of the annular groove 303 and the convex ring 108 in clamping relation makes the sampling hose 3 firmly connected, ensuring no leakage during sample transmission and greatly reducing the risk of sample contamination.
[0027] Reference Figure 3 A silicone pad 109 is provided inside the connecting sleeve 106 , and a cross perforation is provided on the top of the silicone pad 109 , and the top of the silicone pad 109 contacts one end of the sampler 1 .
[0028] Reference Figure 1 and Figure 2 The outer surface of the sampler 1 is provided with a plurality of anti-slip grooves 110 , and the top of the pressing plate 103 is provided with a plurality of anti-slip bumps 105 .
[0029] Reference Figure 6 and Figure 7 , a plurality of placement holes 201 for placing the sampling hose 3 are provided on the top of the placement base 2. The sampling hose 3 is accommodated by providing a plurality of placement holes 201 on the top of the placement base 2 to realize the placement and fixation of the sampling hose 3. The placement holes 201 are distributed in a circular array on the top of the placement base 2. A rotating shaft 203 is welded on one side of the top of the placement base 2, and the outer surface of the rotating shaft 203 is rotatably connected to the cover 204. The design of the rotating shaft 203 and the cover 204 prevents the sampling hose 3 from being contaminated. A plurality of toggling ridges 207 are provided on one side of the top of the cover 204. A baffle 202 is integrally formed on the top of one side of the placement base 2, and one side of the baffle 202 is in contact with one side of the cover 204. A placement block 205 is welded on the top of the cover 204, and the placement block 205 is provided with a placement groove 206, and one end of the sampler 1 can be inserted into the placement groove 206.
[0030] Reference Figure 5 The outer surface of the sampling tube 302 is provided with a scale 304. The scale 304 on the sampling hose 3 is designed to help the operator accurately control the sampling volume under different circumstances. The sampling tube 302 is made of transparent polyethylene.
[0031] The working principle of this embodiment is as follows: when the sampler 1 is needed, the pressing plate 103 is first pressed to drive the pressing rod 101 to move downward. The downward movement of the pressing rod 101 pushes the piston 102 to move downward, thereby exhausting the original air in the sampler 1. The air is squeezed out through the cross perforations on the silicone pad 109 to ensure that negative pressure is formed inside the sampler 1 to prepare for the subsequent suction of liquid. Then, the operator rotates the cover plate 204 on the placement base 2 and inserts the connector 107 at one end of the sampler 1 into the sampling hose 3 in the placement hole 201. The convex ring 108 on the connector 107 is aligned with the annular ring on the sampling hose 3. The card slots 303 are connected to each other, achieving a firm fixation between the two. The sampling tube 302 at the top of the sampling hose 3 is carefully inserted into the liquid to be sampled. Then, the pressing plate 103 is slowly loosened. At this time, the spring 104 is activated, pulling the piston 102 to one side. Under the action of negative pressure, the liquid to be tested is sucked into the sampling hose 3. The scale 304 provided on the sampling hose 3 can intuitively display the dosage of the liquid taken, which helps the operator to grasp the sampling amount. After the sampling is completed, the pressing plate 103 is pressed again. At this time, the force of the spring 104 acts again, and the piston 102 moves in the opposite direction to discharge the liquid in the sampling hose 3. This step ensures a clean and tidy sampling process and avoids cross contamination. After sampling is completed, the sampling hose 3 at the top is removed and discarded to keep the equipment clean. If sampling is required again, just repeat the above steps.
[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
