In the fields of hospitals, laboratories, and public health, accurately detecting the disinfection and sterilization effects of various items, environments, and medical devices is the cornerstone for ensuring medical safety, preventing cross-infection, and meeting environmental protection emission standards.

[0003] Currently, the evaluation of disinfection and sterilization effects mainly relies on sampling and detecting the samples after disinfection. Traditional sampling methods mainly include cotton swab sampling method and reagent tube suction sampling method.

[0004] Specifically, when using the reagent tube suction sampling method, the reagent tube is usually designed as a funnel-shaped structure made of soft material, relying on medical staff to manually squeeze the end to generate suction, so as to suck the sample into the inner cavity. However, this operation method has significant defects: First, the finger pressing area is limited, resulting in a small amount of sample that can be sucked in a single sampling. To reach the required sample amount for detection, multiple repeated samplings are often required, which increases the workload of medical staff, prolongs the sampling time, and reduces work efficiency.

[0005] Therefore, how to provide a sampling device to increase the sample amount of a single sampling and reduce the number of samplings is a technical problem that those skilled in the art need to solve currently. Summary of the Utility Model

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0031] See Figures 1 - 2, a sampling device provided by the present application includes an elastic pressing chamber 1, and the elastic pressing chamber 1 is communicated with a sampling tube 2; a pressing mechanism sleeved outside the elastic pressing chamber 1, the pressing mechanism includes a lower fixing frame 3 for supporting the bottom of the elastic pressing chamber 1, and first pressing plates 4 and second pressing plates 5 which are slidable are symmetrically arranged on both sides of the elastic pressing chamber 1 on the lower fixing frame 3. The upper ends of the first pressing plate 4 and the second pressing plate 5 are jointly slidably connected to an upper fixing frame 6, the upper fixing frame 6 is sleeved outside the top of the elastic pressing chamber 1, and a rebound member 7 is symmetrically arranged between the first pressing plate 4 and the second pressing plate 5; a blocking member for blocking the passage of the sampling tube 2.

[0032] That is to say, the elastic pressing chamber 1 is communicated with the sampling tube 2, and by pressing the elastic pressing chamber 1, the sample can be pushed out through the sampling tube 2 or sucked into the elastic pressing chamber 1.

[0033] The lower fixing frame 3 stably fixes the bottom of the elastic pressing chamber 1 to prevent shaking or deviation during the sampling process. The first pressing plate 4 and the second pressing plate 5 are respectively located on both sides of the elastic pressing chamber 1. The first pressing plate 4 and the second pressing plate 5 can slide on the lower fixing frame 3, and their upper ends are jointly slidably connected to the upper fixing frame 6. When the first pressing plate 4 and the second pressing plate 5 move towards the center, they will squeeze the elastic pressing chamber 1 and make it deformed; the upper fixing frame 6 is sleeved outside the top of the elastic pressing chamber 1 to provide a sliding guide for the first pressing plate 4 and the second pressing plate 5.

[0034] The rebound member 7 is symmetrically arranged between the first pressing plate 4 and the second pressing plate 5 to help the first pressing plate 4 and the second pressing plate 5 quickly return to the initial position; the blocking member is used to block the passage of the sampling tube 2 before and after sampling.

[0035] First, place the elastic pressing chamber 1 inside the pressing mechanism, then use the blocking member to seal the passage of the sampling tube 2 to ensure the sealing of the passage of the sampling tube 2. Next, remove the blocking member, and the operator simultaneously pushes the first pressing plate 4 and the second pressing plate 5 towards the center of the elastic pressing chamber 1, maintains the pressing effect, aligns the sampling tube 2 with the sample, and then releases the first pressing plate 4 and the second pressing plate 5 to suck the sample. After sampling, use the blocking member to seal the sampling tube 2 again to prepare for the next sampling or sample processing.

[0036] In summary, a sampling device provided by the present application simultaneously acts through the first pressing plate 4 and the second pressing plate 5. Compared with the traditional finger pressing method, it increases the pressing area and can apply pressure to the elastic pressing chamber 1 more evenly, thereby generating negative pressure more effectively and promoting the inhalation or ejection of the sample. The rebounding member 7 enables the first pressing plate 4 and the second pressing plate 5 to automatically reset, simplifies the operation process, improves the sampling efficiency, and the combined use of the upper fixing frame 6 and the lower fixing frame 3 provides a stable sliding track for the first pressing plate 4 and the second pressing plate 5, making it easy to operate.

[0037] Optionally, the plugging member can be a sealing cover. The end of the sampling tube 2 is provided with a sampling port, and the sealing cover can be rotatably and sealingly connected to the sampling port. A sealing gasket is provided inside the sealing cover to enhance the sealing effect.

[0038] On the basis of the above embodiment, a plurality of L-shaped hooks 8 are arranged along the circumferential direction at the bottom of the lower fixing frame 3. The L-shaped hooks 8 are used to support the bottom of the elastic pressing chamber 1. Specifically, the number of the L-shaped hooks 8 can be 4.

[0039] That is to say, the L-shaped hooks 8 are arranged along the circumferential direction and can evenly disperse and support the weight of the elastic pressing chamber 1.

[0040] On the basis of the above embodiment, the lower fixing frame 3 includes a first ring 31 and first sliding rails 32 symmetrically arranged on the outer peripheral surface of the first ring 31. The upper fixing frame 6 includes a second ring 61 and second sliding rails 62 symmetrically arranged on the outer peripheral surface of the second ring 61. Both the first ring 31 and the second ring 61 are used for the elastic pressing chamber 1 to pass through. The first sliding rail 32 is provided with a first sliding groove along its length direction, and the second sliding rail 62 is provided with a second sliding groove along its length direction. The bottom ends of the first pressing plate 4 and the second pressing plate 5 are symmetrically provided with first sliders slidably connected to the first sliding groove, and the top ends of the first pressing plate 4 and the second pressing plate 5 are symmetrically provided with second sliders slidably connected to the second sliding groove.

[0041] That is to say, the central hole of the first ring 31 allows the elastic pressing chamber 1 to pass through. Furthermore, the elastic pressing chamber 1 can be stably fixed below. The first sliding rails 32 are symmetrically arranged on the outer peripheral surface of the first ring 31. The first sliding rails 32 are used to guide the movement of the bottoms of the first pressing plate 4 and the second pressing plate 5. The first sliding groove is slidably connected to the first sliders at the bottom ends of the first pressing plate 4 and the second pressing plate 5, ensuring the stable movement of the pressing plates in the horizontal direction.

[0042] Similarly, the central hole of the second ring 61 also allows the elastic pressing chamber 1 to pass through. The second slide rails 62 are symmetrically arranged on the outer peripheral surface of the second ring 61 and are used to guide the movement of the tops of the first pressing plate 4 and the second pressing plate 5. Similar to the first slide rails 32, second chutes are also provided on the second slide rails 62, and the second chutes are slidably connected to the second sliders at the tops of the first pressing plate 4 and the second pressing plate 5 to ensure the stable movement of the pressing plates in the vertical direction.

[0043] In the present application, the first slider and the first chute, and the second slider and the second chute are all in a snap-fit sliding connection, so as to realize that the first slider is always connected with the first chute in a matching manner, and the second slider is always connected with the second chute in a matching manner. Moreover, the snap-fit sliding connection in the present application is a direct application of the existing mature technology.

The rebounding member 7 is arranged between the first fixing plates 41 and the second fixing plates 51, and the rebounding member 7 is a spring.

[0045] Specifically, the first fixing plates 41 and the second fixing plates 51 are symmetrically arranged on the outer walls on both sides of the first pressing plate 4 and the second pressing plate 5 respectively, ensuring that the spring is evenly stressed on both sides, which is beneficial to maintaining the balance and stability of the first pressing plate 4 and the second pressing plate 5. The rebounding member 7 is selected as a spring, and in actual application, an appropriate spring stiffness can be selected according to needs to ensure that both the reset requirement can be met and excessive resistance will not be generated during the pressing process.

[0046] On the basis of the above-mentioned embodiment, anti-slip patterns are provided on the outer walls of the first pressing plate 4 and the second pressing plate 5.

[0047] That is to say, the anti-slip patterns can increase the friction between the user's fingers and the pressing plates, so that during the pressing process, the user's fingers can fit more firmly on the pressing plates and are not prone to sliding or falling off.

[0048] On the basis of the above-mentioned embodiment, referring to Figure 3 , it further includes a leak-proof pipe 9 and a sealing pipe 10.

[0049] That is to say, the leak-proof pipe 9 serves as a connection channel between the elastic pressing chamber 1 and the sealing pipe 10 to ensure that during the sampling process, the sample can smoothly flow from the sealing pipe 10 into the elastic pressing chamber 1. One end of the leak-proof pipe 9 is communicated with the elastic pressing chamber 1, and the other end is connected to the sealing pipe 10.

[0050] In order to further enhance the tightness of the connection and prevent leakage, a locking member is provided on the leak-proof tube 9, which can ensure a tight fit between the leak-proof tube 9 and the sealing tube 10.

[0051] One end of the sealing tube 10 is connected to the leak-proof tube 9, and the other end is connected to the sampling tube 2, so that the sample can smoothly enter the sealing tube 10, the leak-proof tube 9 from the sampling tube 2 and finally flow into the elastic pressing chamber 1 for subsequent analysis. In order to control the flow of the sample and prevent contamination during non-sampling periods, a sealing member is provided on the sealing tube 10. When sampling is not required, the sealing member can block the internal channel of the sealing tube 10, thus ensuring the sealing and safety of the sample.

[0052] Specifically, the sealing member includes a sealing film provided on the inner wall of the sealing tube and a tightening member provided on the outer side of the sealing tube. When the tightening member is twisted clockwise, the sealing film is driven by the tightening ring to perform the sealing and closing operation.
