Description

Technical Field

[0001] The utility model relates to the technical field of cell collection, in particular to a sample cell preservation device convenient for slice collection. Background Technique

[0002] During clinical practice for diagnosis, sometimes it is necessary to take tissue samples from the diseased part of a patient to make slices. During the collection process, after collecting with tools such as a puncture needle, the sample needs to be injected into a preservation tube filled with a preservation solution for sealing, and then sent to a testing institution. After taking it out with a pipette gun, it is tested;

[0003] Existing preservation tubes have the following drawbacks: 1. The diameter of the preservation tube is small (outer diameter 1.2 cm). When injecting the sample into the preservation tube with a long and sharp puncture needle, it may accidentally injure the doctor; 2. The bottom of the preservation tube has a conical shape or a flat bottom. However, when such a preservation tube is placed vertically without a base, it is prone to tipping and skewing, which will undoubtedly increase the cost;

[0004] Publication No. CN221013316U discloses a sample collection and preservation device for cell detection, including a sampling bottle and a sealing cap. An upper-wide and lower-narrow liquid collection hopper is arranged inside the sampling bottle. The liquid collection hopper is connected to the inner wall of the sampling bottle. An external thread is arranged on the outer wall of the upper part of the sampling bottle, and an internal thread matching the external thread is arranged on the inner wall of the sealing cap. The sealing cap is threadedly connected to the outer wall of the sampling bottle. This device can facilitate the transfer of tissue into the tube by a puncture needle, without increasing the usage amount of the preservation solution, reducing the operation difficulty and saving the usage cost. However, the following problems still exist in the actual use of this patent:

[0005] The above device increases the convenience of use by shortening the tube body depth and expanding the surface area of the tube body. However, both the above device and existing preservation tubes use a sealing cap installed by threads for sealing, and the threaded installation is not convenient for the disassembly and assembly of the sealing cap.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please refer to Figures 1-5 ,the present utility model provides a technical solution: a sample cell preservation device convenient for slicing and collection, including a storage tube body 1;

[0028] A flaring assembly 2 is provided at the top of the storage tube body 1, and a vertical placement mechanism 3 is provided at the bottom of the storage tube body 1. The flaring assembly 2 includes an installation outer ring 201 fixed to the outer side of the top of the storage tube body 1. A plurality of rotating shafts 202 are rotatably installed at the top of the installation outer ring 201. A gear 204 is fixedly installed at the top end of the rotating shaft 202. A rotating blade 203 is fixedly connected to the top of the rotating shaft 202; the number of rotating shafts 202 is not less than three

[0029] Among them, the rotating shafts 202 are evenly distributed. The adjacent rotating blades 203 are in contact with each other and a sealing strip is fixedly installed at the contact edge. The rotating blade 203 is in contact with the top end of the storage tube body 1; a waterproof coating is attached to the bottom surface of the rotating blade 203, which can prevent the preservation liquid from leaking out from the contact part between the rotating blade 203 and the storage tube body 1.

[0030] An outer ring strip is fixedly installed at the bottom of the installation outer ring 201. One side of the top surface of the outer ring strip is fixedly connected with a spring sleeve 205. A support spring 206 is fixedly connected inside the spring sleeve 205. The top end of the support spring 206 is fixedly connected with a movable rod 207. The movable rod 207 is slidably connected with the spring sleeve 205; the support spring 206 can always lift the movable rod 207 to ensure that the clamping head 209 is engaged with the gear 204.

[0031] The top end of the movable rod 207 is fixedly connected with a clamping head 209. A pressing convex plate 208 is fixedly connected to the outer side of the top of the movable rod 207. The clamping head 209 is engaged with one gear 204; the clamping head 209 prevents one gear 204 from rotating randomly, thus affecting the sealing performance of the storage tube body 1.

[0032] A fixed sleeve 210 is sleeved on the outer side of the bottom of the storage tube body 1. A toothed ring 211 is fixedly connected to the inner side of the fixed sleeve 210. A guiding cover 212 is fixedly connected to the bottom surface of the toothed ring 211. The guiding cover 212 is conical. The maximum width of the guiding cover 212 is much larger than the top opening of the storage tube body 1. The toothed ring 211 can be engaged with the gear 204; when the guiding cover 212 is reversely buckled on the top of the storage tube body 1, it can guide the puncture needle to insert into the storage tube body 1.

[0033] The vertical placement mechanism 3 includes a fixed ring 301 fixed to the bottom of the storage tube body 1. The fixed ring 301 is located above the fixed sleeve 210. Clamping hooks 302 are symmetrically and fixedly connected to the outer side of the fixed ring 301. A sliding groove 303 is opened inside the fixed sleeve 210. The sliding groove 303 is slidably connected with the clamping hooks 302; the clamping hooks 302 can be inserted into the sliding groove 303 and slide.

[0034] A clamping groove 304 is formed inside the fixed sleeve 210, and the clamping groove 304 is located on one inner side of the sliding groove 303.

[0035] A bent block is provided at the bottom end of the clamping hook 302. Rubber blocks 305 are fixedly connected to both the top and bottom of the bent block. The rubber blocks 305 are engaged with the clamping groove 304; when the rubber blocks 305 are inserted into and detached from the clamping groove 304, deformation occurs.

[0036] Working principle: Before using the sample cell preservation device convenient for slicing and collection, it is necessary to first check the overall condition of the device to determine that it can work normally. According to Figure 1 - Figure 5 As shown, when it is necessary to inject the storage tube body 1, first rotate the guiding cover 212 so that the clamping hook 302 drives the rubber block 305 to be withdrawn from the clamping groove 304 and slide in the sliding groove 303, and then pull down the guiding cover 212 so that the clamping hook 302 is separated from the fixed ring 301; through the downwardly installed guiding cover 212, the storage tube body 1 can be detached from a common test tube rack and placed independently, avoiding the random dumping and rolling of the storage tube body 1 when there is no test tube rack. For some test tubes with flat bottoms, the guiding cover 212 can also increase the stability when the test tube is placed vertically alone;

[0037] Turn the removed guiding cover 212 together with the fixed sleeve 210 so that the fixed sleeve 210 is located below. Then, while holding the storage tube body 1 with one hand, press the pressing convex plate 208 with the thumb, so that while the movable rod 207 moves downward, the clamping head 209 is disengaged from the gear 204 until the clamping head 209 moves to a position lower than the rotating blade 203. Then, put the fixed sleeve 210 outside the gear 204 so that the gear 204 meshes with the gear ring 211. Then, rotate the guiding cover 212 so that the fixed sleeve 210 drives the gear ring 211 to rotate, thereby causing the rotating shaft 202 to rotate and the rotating blade 203 to rotate outwards. At this time, the guiding cover 212 can guide the puncture needle to insert into the storage tube body 1 to store the collected cell sample, avoiding misalignment of the puncture needle due to a smaller tube diameter, and further avoiding accidental injury to the operator's hand by the puncture needle;

[0038] The rotating blade 203 in the unfolded state can prevent the clamping head 209 from moving upward under the action of the support spring 206, so that the pressing convex plate 208 does not need to be installed at this time.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
