Description

Technical Field

[0001] The utility model belongs to the technical field of pathological sample containers, in particular to a pathological sample container. Background Art

[0002] In the fields of medical diagnosis and pathological analysis, the collection, storage, and transportation of pathological samples are crucial. As a key tool in the pathological sample container, the sealing and ease of use of blood collection tubes directly impact the integrity of the sample and the accuracy of the test.

[0003] In existing blood collection tube designs, the tube and the sealing cap are typically sealed using a threaded connection. While this connection ensures a certain degree of sealing reliability, it takes a considerable amount of time to rotate the sealing cap multiple times. This can significantly reduce work efficiency in certain situations when many blood collection tubes need to be sealed or opened.

[0004] Some blood collection tubes have a sealing cap that fits tightly over the tube opening. This allows for direct opening, saving time, but requires considerable force. Opening the sealing cap with force can easily cause internal oscillations in the tube, mixing the centrifuged samples and affecting certain test results. Utility Model Content

[0005] The purpose of the utility model is to provide a pathology sample container, which can open the sealing cover on the blood collection tube with relatively easy and labor-saving operation.

[0024] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0025] Example

[0026] A pathological sample container described in this embodiment, such as Figures 1 to 7 As shown, it includes a blood collection tube 1, the tube mouth of the blood collection tube 1 is covered with a sealing cover 3, and the blood collection tube 1 and the sealing cover 3 are both made of plastic material.

[0027] A sealing plug 2 is provided between the tube opening of the blood collection tube 1 and the inner top of the sealing cap 3. The sealing plug 2 is made of an elastic material. The sealing plug 2 is made of a rubber material, which has high elasticity and sealing performance. In addition to rubber, the sealing plug 2 can also be made of silicone.

[0028] The diameter of the tube opening of the blood collection tube 1 is smaller than the diameter of the sealing plug 2, so that the sealing plug 2 covers the tube opening of the blood collection tube 1 and plays a sealing role.

[0029] like Figure 1 and Figure 2 As shown, two groups of latch teeth are provided on the outer wall of the blood sampling tube 1, and the two groups of latch teeth are symmetrically distributed on the outer wall of the blood sampling tube 1; each group of latch teeth includes a plurality of first latch teeth 4 distributed sequentially from bottom to top, and the inner wall of the sealing cover 3 is fixed with second latch teeth 5 engaged with each group of latch teeth. In this way, there are two second latch teeth 5 on the inner wall of the sealing cover 3, and they are symmetrically distributed on the sealing cover 3; when in use, the second latch teeth 5 are stuck directly below any one of the first latch teeth 4 to limit the upward movement of the sealing cover 3.

[0030] like Figure 5 As shown, the inner wall of the sealing cap 3 is fixed with several sliders 6 distributed along its circumference. There are two sliders 6, symmetrically distributed on the inner wall of the blood collection tube 1. The sliders 6 and the second latches 5 are aligned at 90 degrees along the circumference of the sealing cap 3. The outer wall of the blood collection tube 1 is provided with a first slot for the sliders 6 to slide downward. When the sliders 6 are positioned within the first slot, the second latches 5 engage with the first latches 4, preventing the sealing cap 3 from being removed upward. During production, the first and second latches 4 are configured in a serrated pattern, allowing the second latches 5 to move downward along the path of the first latches 4, but not upward along the path of the first latches 4. As the second latches 5 move downward along the path of the first latches 4, the sliders 6 slide downward along the first slot. It is also worth mentioning that when the second tooth 5 moves downward along the first tooth 4, the material of the second tooth 5 follows the sealing cover 3, which is plastic material and has a certain elastic deformation ability, so that the second tooth 5 can move downward along the first tooth 4.

[0031] like Figure 7 As shown, a second chute for sliding the slider 6 upward is provided on the outer wall of the blood collection tube 1 corresponding to one side of the first chute. The second chute is located on the counterclockwise side of the first chute (as shown in FIG. Figure 5 (As shown), an open slot is defined between the first and second chutes for the slider 6 to slide through. During use, the sealing cover 3 is rotated to allow the slider 6 to pass through the open slot from the first chutes and into the second chutes. When the slider 6 enters the second chutes, the second latching teeth 5 are misaligned with the first latching teeth 4 and no longer engage with each other. The slider 6 can then be withdrawn from the second chutes and the sealing cover 3 can be removed.

[0032] The width of the first latching tooth 4 is smaller than the distance between the first and second chutes. This allows the sealing cover 3 to be removed after the slider 6 enters the second chutes without restricting the second latching tooth 5 and the first latching tooth 4. The width of the first and second chutes is equal to the width of the slider 6. The slider 6 can only slide up and down along the first and second chutes, preventing the sealing cover 3 from shaking.

[0033] like Figure 3 and Figure 4 As shown, the second latch 5 and the slider 6 are at the same level, and the opening is lower than the level of the first latch 4 at the bottom. This design ensures a tighter fit between the sealing cap 3 and the blood collection tube 1, preventing the slider 6 from accidentally entering the second slot due to the sealing cap 3's rotation. During use, since the second latch 5 and the slider 6 are at the same level, when the second latch 5 and the bottom-most first latch 4 engage, the opening is located below the slider 6. To remove the sealing cap 3, the slider 6 must enter the second slot. This requires pressing the sealing cap 3. The elastic deformation of the sealing plug 2 causes the sealing cap 3 to move downward a certain distance, causing the slider 6 to move downward until it is at the same level as the opening. The sealing cap 3 is then rotated, and the slider 6 enters the second slot through the opening. The second latch 5 is misaligned with the first latch 4 due to the rotation of the sealing cap 3. The slider 6 then exits upward along the second slot, allowing the sealing cap 3 to be removed from the blood collection tube 1.

[0034] In actual use:

[0035] When the sealing cover 3 is put on, the slider 6 slides into the first slot. At the same time, the second latch 5 slides into the slot from top to bottom along the distribution path of the first latch 4. The slider 6 cooperates with the first slot to limit the rotation of the sealing cover 3, maintaining the engagement between the second latch 5 and the first latch 4. The sealing plug 2 covers the tube mouth of the blood collection tube 1, maintaining the seal, and achieving a tight connection between the sealing cover 3 and the blood collection tube 1. When removing the sealing plug 2, press the sealing cover 3 to move the slider 6 downward to align with the opening slot, and then rotate the sealing cover 3 to allow the slider 6 to enter the second slot. At the same time, the second latch 5 and the first latch 4 are no longer engaged, and the slider 6 withdraws from the second slot. The sealing cover 3 can be quickly and conveniently removed, thereby saving time and effort in opening the sealing cover 3.
