Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical test sample collection and anti-contamination device. Background Technology

[0002] In modern medical diagnostic systems, biological sample testing occupies a central position. Samples such as urine, body fluids, and blood contain rich physiological and pathological information, and their test results are crucial for disease diagnosis, treatment planning, and prognosis assessment. However, these valuable medical test samples face the risk of contamination by external microorganisms and chemicals at every stage of collection, transfer, and storage.

[0003] Currently, traditional sample collection devices lack reliable fixing and protective structures after the sample tube is placed. The sample tube is easily tipped over or slipped due to external impacts or shaking, leading to sample leakage and contamination. Furthermore, existing devices struggle to stably clamp the sample tube immediately after collection, failing to effectively prevent contamination from contact with the external environment during transfer. Once the sample is contaminated, it can not only lead to inaccurate test results and mislead clinical judgment but may also delay the patient's optimal treatment time, causing serious consequences. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a medical testing sample collection and anti-contamination device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A medical test sample collection anti-contamination device, comprising:

[0007] The top plate has several circular grooves evenly distributed inside to accommodate sample tubes. Several clamping blocks are slidably arranged on the outer periphery of each circular groove inside the top plate. The bottom of the clamping blocks extends out of the bottom surface of the top plate, and the sliding path of the clamping blocks is parallel to the radial direction of the circular grooves.

[0008] The chassis is vertically slidably disposed directly below the circular groove, and a connecting plate is rotatably disposed between the surface of the chassis and the bottom of the clamping block;

[0009] The base plate is fixed directly below the top plate;

[0010] Adsorption components are used to securely connect the base plate and the chassis.

[0011] When the filled sample tube sinks under gravity, it will press down on the base plate and be fixed to the base plate by the adsorption component. As a result, the clamping blocks are pulled together by the connecting plate, and finally the clamping surface of the clamping block is in contact with the peripheral side of the sample tube.

[0012] Preferably, the diameter of the circular groove is larger than the diameter of the sample tube, and the arc-shaped surface of its inner wall is detachably provided with a velvet cloth, the velvet side of which is attached to the circumferential side of the sample tube.

[0013] Preferably, the clamping surface of the clamping block is provided with an anti-slip layer, which is in close contact with the peripheral side of the sample tube.

[0014] Preferably, the bottom surface of the top plate is provided with a plurality of sliding grooves evenly distributed on the circumferential side of each circular groove. The sliding grooves are parallel to the radial direction of the circular grooves, and the end of the sliding groove pointing to the circular groove is not connected to the circular groove.

[0015] Preferably, a slider is fixed to the bottom surface of the clamping block, the slider is slidably disposed inside the groove, and the end of the connecting plate near the clamping block is rotatably engaged with the slider.

[0016] Preferably, the adsorption element is a magnet or a suction cup.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses the gravity of the sample tube to press down on the base plate, which drives the clamping blocks to close together and clamp the sample tube. No manual operation is required. It can stably clamp the sample tube immediately after sample collection, preventing the sample tube from shaking or slipping due to external forces. It effectively prevents the sample from coming into contact with the outside world and being contaminated, ensuring the original state of the sample during the transfer process.

[0019] 2. The soft velvet cloth on the inner wall of the circular groove of this utility model can cushion the sample tube, reduce the collision damage to the sample tube during placement and transfer, and further improve the stability of the sample tube, reducing the risk of sample leakage and contamination caused by sample tube shaking.

[0020] 3. This utility model achieves automatic clamping of sample tubes through a mechanical structure, eliminating the need for complex control systems and power devices. It has a simple structure and low cost. At the same time, the placement and removal of sample tubes are convenient, improving the efficiency of sample collection. Attached Figure Description

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figure 1 As shown, a medical test sample collection anti-contamination device includes a top plate 1 and a bottom plate 6. The bottom plate 6 is fixed directly below the top plate 1, and a number of connecting shafts are connected between the top plate 1 and the bottom plate 6 to provide spaced support.

[0031] Preferred, such as Figure 4-5 As shown, the top plate 1 has several circular grooves 2 evenly distributed inside to accommodate sample tubes. The diameter of the circular grooves 2 is larger than the diameter of the sample tubes so that the sample tubes can be smoothly placed into the circular grooves 2. The arc-shaped surface of its inner wall is detachably provided with a velvet cloth 7 via Velcro. The velvet side of the velvet cloth 7 is attached to the periphery of the sample tube. The velvet cloth 7 is soft and can provide initial cushioning and fixation for the sample tubes without damaging them. At the same time, the Velcro is convenient for the replacement and cleaning of the velvet cloth 7.

[0032] Inside the top plate 1, several clamping blocks 3 are slidably arranged on the outer periphery of each circular groove 2. The clamping surface of the clamping block 3 is glued with an anti-slip layer 8. The anti-slip layer 8 is tightly attached to the periphery of the sample tube. The anti-slip layer 8 is made of rubber and is tightly attached to the periphery of the sample tube, which can increase the friction between the sample tube and the sample tube and prevent the sample tube from sliding.

[0033] The sliding path of the clamping block 3 is parallel to the radial direction of the circular groove 2, so that the clamping block 3 can move along the radial direction of the circular groove 2, thereby realizing the clamping and releasing of the sample tube.

[0034] The chassis 4 is vertically slidably positioned directly below the circular groove 2. A connecting plate 5 is rotatably positioned between the surface of the chassis 4 and the bottom of the clamping block 3. The two ends of the connecting plate 5 are rotatably connected to the chassis 4 and the clamping block 3 through pins.

[0035] The suction component is used to fix the base plate 6 and the chassis 4. The suction component is set as a magnet or a suction cup.

[0036] When a magnet is selected, magnet blocks that attract each other are installed on the base plate 6 and the base plate 4 respectively. When the base plate 4 slides down under the gravity of the sample tube, the magnet blocks can fix the base plate 4 on the base plate 6, thereby maintaining the clamping state of the clamping block 3 on the sample tube.

[0037] When a suction cup is selected, the bottom surface of the base plate 6 is fixed with a suction cup directly below the base plate 4. When the base plate 4 slides downward under the gravity of the sample tube, the suction cup can adsorb the base plate 4 onto the base plate 6, thereby maintaining the clamping state of the clamping block 3 on the sample tube.

[0038] Preferred, such as Figure 2-3 As shown, the bottom of the clamping block 3 extends out of the bottom surface of the top plate 1. The bottom surface of the top plate 1 is evenly provided with several sliding grooves 9 on the sides of each circular groove 2. The sliding grooves 9 are parallel to the radial direction of the circular groove 2. The end of the sliding groove 9 pointing to the circular groove 2 is not connected to the circular groove 2 to avoid the sample tube from contacting the components inside the sliding groove 9.

[0039] A slider 10 is fixed on the bottom surface of the clamping block 3. The slider 10 is slidably disposed inside the slide groove 9. The end of the connecting plate 5 near the clamping block 3 is rotatably engaged with the slider 10. The engagement between the slider 10 and the slide groove 9 can restrict the movement direction of the clamping block 3 and ensure that the clamping block 3 slides stably along the radial direction.

[0040] Working principle: When it is necessary to collect a sample, the empty sample tube is placed in the circular groove 2. The sample tube is located between the velvet cloths 7. The velvet cloths 7 play a preliminary positioning and buffering role for the sample tube. After the sample is collected, the sample tube filled with the sample will press down on the base plate 4 due to gravity. The base plate 4 slides vertically downward.

[0041] During the sliding process of the chassis 4, the connecting plate 5 pulls the slider 10 to move radially towards the center of the circular groove 2 in the groove 9, thereby causing the clamping blocks 3 to come together.

[0042] When the base plate 4 slides to contact the base plate 6, the adsorption element (magnet) fixes the base plate 4 to the base plate 6. At this time, the clamping surface of the clamping block 3 is closely attached to the periphery of the sample tube through the anti-slip layer 8, so as to achieve stable clamping of the sample tube and prevent the sample tube from shaking or tipping during transfer and storage, effectively avoiding sample contamination.

[0043] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
