Description

Technical Field

[0001] This utility model relates to the field of sample collection technology, specifically to a sample collection device. Background Technology

[0002] As a crucial auxiliary tool in clinical testing, the technological development of blood sample collection stents is closely linked to the increasing demands for efficiency and safety in medical testing. In traditional blood sample collection, healthcare workers manually hold the blood collection tubes for dispensing, labeling, and temporary storage, posing risks such as tube slippage, sample mixing, and biocontamination. This complexity increases significantly, especially in batch collection scenarios. Early stents often employed a fixed slot design, making it difficult to accommodate different tube sizes and lacking structural optimizations to prevent tipping and cross-contamination. With the advancement of standardization and automation in clinical testing, modern blood collection stents have gradually incorporated innovative elements such as modular design, ergonomic tilt angles, and antibacterial coatings. Some high-end products even integrate intelligent identification modules, enabling sample traceability management through barcode scanning and positioning technology. This technological evolution reflects a transformation from basic support functions to a precise and intelligent medical auxiliary system.

[0023] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0024] Please see Figures 1-3As shown, this embodiment discloses a sample collection device, including a frame 101, an external support device, and a collision protection device; the frame 101 is used to place the vacuum blood collection tube 102; the external support device is used to support the frame 101 to prevent the frame 101 from tipping over; the collision protection device is installed on the frame 101 and is used to support the vacuum blood collection tube 102.

[0025] The collision protection device includes a rubber seat 103, a slider 104, and an elastic element 105. The frame 101 is provided with several sliding holes 106. The slider 104 is slidably installed inside the sliding holes 106. The sliding holes 106 are provided with stepped grooves 107. The elastic element 105 is disposed inside the stepped grooves 107. The elastic element 105 is sleeved on the slider 104 and connected to the slider 104. The rubber seat 103 is disposed at the end of the slider 104. The vacuum blood collection tube 102 is used to be placed on the rubber seat 103.

[0026] This utility model mainly includes a frame 101, an external support device, and a collision protection device. In actual use, before placing the vacuum blood collection tube 102, the operator first needs to use the external support device to fix the position of the frame 101 so that it will not easily tip over. Then, the vacuum blood collection tube 102 is placed inside the frame 101. During the descent of the vacuum blood collection tube 102, it first contacts the rubber seat 103 to form a buffer. The rubber seat 103 provides a first layer of cushioning for the vacuum blood collection tube 102. When the vacuum blood collection tube... After 102 contacts the rubber seat 103, the rubber seat 103 squeezes the slider 104 and the elastic element 105. The slider 104 slides inside the sliding hole 106, and the elastic element 105 provides double buffering for the vacuum blood collection tube 102. At the same time, the rubber seat 103 supports the vacuum blood collection tube 102. In addition, the external support device supports the frame 101, making it difficult for the frame 101 to tip over. The advantage of this setting is that when collecting blood from the vacuum blood collection tube 102, the vacuum blood collection tube 102 is supported and buffered, thus making the vacuum blood collection tube 102 less prone to damage.

[0027] In some embodiments, the frame 101 is provided with a mounting hole 108, and the vacuum blood collection tube 102 is used to pass through the mounting hole and be placed on the rubber seat 103.

[0028] In actual use, the purpose of setting the mounting hole is to facilitate the storage of the vacuum blood collection tube 102, so that the vacuum blood collection tube 102 can pass through the frame 101 for storage.

[0029] In some embodiments, limit plates 109 are provided at both ends of the slider 104. The limit plate 109 located below the slider 104 contacts the end face of the frame 101, and the limit plate 109 located above the slider 104 is used to contact the bottom surface of the stepped groove 107.

[0030] In actual use, the purpose of setting two limit plates 109 is to prevent the slider 104 from disengaging from the sliding hole 106.

[0031] In some embodiments, the elastic element 105 is either a spring or a sheet spring.

[0032] As an optional implementation, in this embodiment, the elastic element 105 is a spring, one end of which is connected to the end face of the stepped groove 107, and the other end is connected to the slider 104.

[0033] In some embodiments, the external support device includes a first connecting rod 110, a second connecting rod 111, and an adsorption assembly. One end of the first connecting rod 110 and the second connecting rod 111 is hinged to the side of the frame 101, and the other end of the first connecting rod 110 and the second connecting rod 111 is hinged to the adsorption assembly, which is used to adsorb onto the carrier.

[0034] In actual use, the first link 110 and the second link 111 rotate and open, so that the first link 110, the second link 111 and the installed carrier form a stable triangular structure, which makes the frame 101 more stable during installation.

[0035] In some embodiments, the adsorption assembly includes a rotating block 112, a screw 113, and a suction cup 114. The rotating block 112 is rotatably mounted on both the first connecting rod 110 and the second connecting rod 111. The screw 113 is threaded onto the rotating block 112, and the suction cup 114 is fixedly mounted on the end of the screw 113.

[0036] In actual use, when the staff needs to fix the frame 101, they need to rotate the screw 113 to adjust the height of the suction cup 114, and they can also rotate the rotating block 112 to adjust the installation angle of the suction cup 114, so that the frame 101 can remain stable no matter what kind of carrier it is installed on.

[0037] In some embodiments, the first link 110 and the second link 111 are both hinged to the frame 101 via a rotating protrusion 116.

[0038] In actual use, the purpose of setting the rotating protrusion 116 is to facilitate the hinge connection between the first link 110 and the second link 111 to the frame 101. Setting the rotating protrusion 116 also makes it easier to install the rotating protrusion 116.

[0039] In some embodiments, the rotating block 112 is provided with a threaded hole 117, and the screw 113 is threadedly connected to the threaded hole 117.

[0040] In actual use, the purpose of setting the threaded hole 117 is to facilitate the threaded connection between the rotating block 112 and the screw 113; when in use, the screw 113 can be rotated to adjust the overall height of the suction cup 114, thereby adapting it to the mounting plane.
