DETAILED DESCRIPTION

[0029] The utility model will be described in further detail below in conjunction with the drawings and specific embodiment:

[0030] The embodiment aims at providing a kind of pathological tissue specimen preservation device, it is mainly used to preserve pathological tissue sample, to effectively solve the problem that current preservation bottle cannot limit the free movement of sample in bottle and sample is in unstable state and is easily damaged in transport process.

[0031] A kind of pathological tissue specimen preservation device, including bottle body 1 and with bottle body 1 detachable lower cover 2, such as Figure 1 And Figure 2 It also includes upper cover 3, protection cylinder 4, placement basket 5 and connecting rod 6.

[0032] Lower cover 2 is screw thread cover, its upper end surface is equipped with the connecting ring 201 extending upwards, connecting ring 201 and lower cover 2 are integrated structure, the outer wall of connecting ring 201 is provided with outer thread, the inner circle of connecting ring 201 forms placement hole, placement hole extends downwards and penetrates lower cover 2.

[0033] The inner wall of the upper cover 3 is provided with an internal thread, and the upper cover 3 is threadedly connected to the connecting ring 201.

[0034] The upper end of the guard cylinder 4 is arranged on the lower cover 2, and in this embodiment, the top of the outer wall of the guard cylinder 4 is provided with a fixing ring 405 which overlaps the connecting ring 201, as shown in Figure 2 When the upper cover 3 is threadedly connected to the lower cover 2, the fixing ring 405 of the guard cylinder 4 is limited between the connecting ring 201 and the upper cover 3.

[0035] The upper end and the lower end of the guard cylinder 4 extend downward into the bottle body 1 through the placement hole, the guard cylinder 4 has an open upper placement cavity, and the side wall of the guard cylinder 4 is provided with a plurality of first filter holes 404 which are penetrated through and allow the preservative liquid to pass through while intercepting the sample.

[0036] The placement basket 5 is placed in the guard cylinder 4 and is mainly used for placing the sample, and the placement basket 5 is fixedly connected with the connecting rod 6 between the upper cover 3, so that the placement basket 5 and the upper cover 3 are fixedly connected as a whole. The side wall of the placement basket 5 is provided with a plurality of second filter holes 501 which are penetrated through and allow the preservative liquid to pass through while intercepting the sample.

[0037] In this embodiment, the sample is placed in the placement basket 5, the placement basket 5 is placed in the guard cylinder 4, the guard cylinder 4 can limit the activity range of the sample, prevent the sample from separating from the placement basket 5, and limit the free activity of the sample inside the bottle body 1, so that the sample is relatively kept in a stable state and is prevented from being damaged by colliding with the bottle body 1. The guard cylinder 4 is provided with the first filter holes 404, and the placement basket 5 is provided with the second filter holes 501, so that the preservative liquid in the bottle body 1 can enter the guard cylinder 4 and the placement basket 5 to immerse the sample.

[0038] When the sample needs to be taken out, the lower cover 2 is first opened, so that the lower cover 2, the guard cylinder 4, the placement basket 5 and the upper cover 3 are separated from the bottle body 1, and the guard cylinder 4 and the placement basket 5 discharge the preservative liquid therein through the filter holes, so that the sample is separated from the tissue fluid, the situation that the preservative liquid needs to be poured out when the sample is taken out can be avoided, the replacement and waste of the preservative liquid are reduced, and the method is especially suitable for the situation that the sample is transported to a place which does not have the same preservative liquid; then the upper cover 3 is opened, so that the upper cover 3 and the placement basket 5 are separated from the guard cylinder 4, so as to take out the sample and reduce the damage and pollution to the sample in the taking-out process.

[0039] Further, as shown in Figure 3The placement cavity includes an upper cavity 401 and a lower cavity 402. The inner diameter of the lower cavity 402 is smaller than that of the upper cavity 401, forming a limiting step surface 403 between the upper cavity 401 and the lower cavity 402 to facilitate the positioning of the placement basket 5. A limiting ring 502 is provided on the side wall of the placement basket 5. The limiting ring 502 and the placement basket 5 are an integral structure. The limiting ring 502 and the inner wall of the protective sleeve 4 are in clearance fit. The limiting ring 502 is located at the top of the placement basket 5. When the limiting ring 502 overlaps on the limiting step surface 403, the placement basket 5 is located in the lower cavity 402. The bottom of the placement basket 5 and the bottom of the lower cavity 402 maintain a gap. The bottom of the protective sleeve 4 has a first filter hole 404 and the bottom of the placement basket 5 has a second filter hole 501. The gap between the bottom of the placement basket 5 and the bottom of the lower cavity 402 can prevent the first filter hole 404 and the second filter hole 501 from overlapping and reducing the actual effective pore size, thus avoiding affecting the flow efficiency of the preservation liquid.

[0040] Furthermore, the diameter of the outer wall of the placement basket 5 is smaller than the inner diameter of the lower cavity 402, so that there is a gap between the placement basket 5 and the cavity wall of the lower cavity 402. Similarly, in order to avoid the overlap of the first filter hole 404 and the second filter hole 501 and reduce the actual effective filter hole diameter, the efficiency of the preservation liquid passage should be avoided.

[0041] Furthermore, at least two sets of connecting rods 6 are evenly arranged around the circumference. The upper end of the connecting rod 6 is fixedly connected to the upper cover 3, and the lower end of the connecting rod 6 is fixed on the limiting ring 502 to prevent the connecting rod 6 from being located in the middle of the placement basket 5 and affecting the space of the placement basket 5.

[0042] Furthermore, such as Figure 4 A horizontal anti-buoyancy plate 7 is fixedly installed on the connecting rod 6. The anti-buoyancy plate 7 is located above the placement basket 5. The anti-buoyancy plate 7 is mainly used to intercept the sample, mainly targeting the situation where fat samples, alveolar samples, etc. have a density less than the preservation liquid and float. When this device is installed, the anti-buoyancy plate 7 is located in the area inside the bottle body 1, which can block the sample from floating upward from above and ensure that the sample is completely immersed in the preservation liquid.
