Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for adding physiological saline to test tubes. Background Technology

[0002] Test tube racks are basic instruments used to hold test tubes. In clinical practice of medical testing, patient urine, blood, and other test samples are placed in test tubes for analysis. During the testing process, saline solution needs to be added to the test tubes. Currently, in hospitals, when testing test samples, laboratory personnel need to place the test tubes on a test tube rack, let them stand for a period of time, and then add saline solution to mix with the test sample before proceeding with the analysis. When there are many test tubes containing test samples, laboratory personnel need to frequently draw saline solution and add it to each test tube individually. During this operation, multiple test tubes are exposed. If the laboratory personnel accidentally bump into a test tube and damage it while frequently adding saline solution, there is a possibility of leakage of the test sample. Therefore, there is a safety hazard in this operation. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] This utility model embodiment provides a saline solution addition device for test tubes, including a test tube rack 1 and multiple test tubes 11, and a protective chamber 2. The protective chamber 2 has a cavity for placing the test tube rack 1 and multiple test tubes 11. A door 21 that can be opened and closed is provided at one end of the protective chamber 2. The top of the protective chamber 2 has a slot that connects to the interior of the cavity, so that the top of the protective chamber 2 is an open design. A support plate 22 is fixedly provided in the cavity of the protective chamber 2 near the top. The support plate 22 has multiple through holes 23. The arrangement order of the multiple through holes 23 is the same as the arrangement order of the multiple test tubes 11 on the test tube rack 1. A tubular liquid storage tube 24 is provided at the bottom of the support plate 22 corresponding to each through hole 23. Each liquid storage tube 24 has a liquid outlet hole 25 at the bottom.

[0031] A square-section adjusting rod 3 is horizontally positioned above the support plate 22. Both ends of the adjusting rod 3 are slidably connected to the inner walls of the two end chambers of the protective chamber 2. At the bottom of the adjusting rod 3, corresponding to the position of each liquid storage tube 24, an insertion rod 31 is provided. The top end of each insertion rod 31 is fixedly connected to the adjusting rod 3, and the bottom end of each insertion rod 31 extends into the corresponding liquid storage tube 24, directly blocking the liquid outlet 25. A pulling plate 32 is positioned above the adjusting rod 3. The bottom end is fixedly connected to the adjusting rod 3, and the top end of the pulling plate 32 extends a distance towards the upper area of ​​the protective chamber 2; a silicone pad 33 is fixedly installed at the bottom end of each insertion rod 31, and a tubular extension tube 26 is fixedly installed at the top end of each liquid storage tube 24. The internal tubular structure of the extension tube 26 is connected to the internal tubular structure of the liquid storage tube 24. The pulling plate 32 and the adjusting rod 3 are made of metal, and the protective chamber 2, the support plate 22, the liquid storage tube 24, and the extension tube 26 are all made of transparent material.

[0032] When in use, the chamber door 21 can be opened and the test tube rack 1 containing multiple test tubes 11 can be placed into the chamber of the protective chamber 2. During operation, the position of multiple test tubes 11 can be observed through the transparent protective chamber 2 to ensure that multiple test tubes 11 correspond to multiple liquid storage tubes 24 below the tray 22. Then, the chamber door 21 is closed and the test samples collected in the test tubes 11 are allowed to stand for a period of time.

[0033] During the waiting process, saline solution can be added to multiple storage tubes 24 through the open slotted area above the protective chamber 2. The bottom end of the insertion rod 31 extending into each storage tube 24 below the adjusting rod 3 will block the outlet hole 25 at the bottom of the storage tube 24. Combined with the weight of the metal pulling plate 32 and the adjusting rod 3, the multiple insertion rods 31 are subjected to downward pressure from the adjusting rod 3 and the pulling plate 32, so that the silicone pad 33 at the bottom of the insertion rod 31 can seal the outlet hole 25 at the bottom of the storage tube 24, so that the saline solution stored in the storage tube 24 will not be discharged from the outlet hole 25.

[0034] After the test sample in test tube 11 has been left to stand for a specified time, the pull plate 32 can be pulled upwards, causing the pull plate 32 to move the adjusting rod 3 and multiple insertion rods 31 upwards. As the silicone pad 33 at the bottom of the insertion rod 31 disengages from the outlet hole 25 at the bottom of the liquid storage tube 24, the outlet hole 25 at the bottom of the liquid storage tube 24 will be opened, allowing the saline solution in the liquid storage tube 24 to flow downwards through the outlet hole 25 into the corresponding multiple test tubes 11 and mix with the collected test sample. Then, after the test sample containing saline solution in the multiple test tubes 11 has been left to stand for a period of time, the warehouse can be opened, the test tube rack 1 can be taken out, and the test sample in the multiple test tubes 11 can be tested.

[0035] After the test tube rack 1 and multiple test tubes 11 are placed into the chamber of the protective chamber 2, they will be protected by the protective chamber 2 and the support plate 22, so that the test tubes 11 will not be touched by the testing personnel. This can prevent the leakage of the test sample in the test tubes 11 due to the operation error of the testing personnel. At the same time, by pulling the pull plate 32, multiple inserts 31 below the adjusting rod 3 can be moved upward, so that the silicone pad 33 at the bottom of the insert 31, which originally sealed the liquid outlet 25 at the bottom of the liquid storage tube 24, will be removed, allowing the saline in the liquid storage tube 24 to flow downward into the multiple test tubes 11. This completes the synchronous addition of saline to multiple test tubes 11, avoiding the safety hazards caused by the testing personnel adding saline to multiple test tubes 11 one by one in the existing technology.

[0036] In a further preferred embodiment, a support plate 4 is provided at the bottom of the chamber of the protective chamber 2. The support plate 4 is slidably connected to the inner wall of the chamber of the protective chamber 2. The support plate 4 is provided with a groove 41 for placing the test tube rack 1. A vertical track groove 27 is provided on one side of the protective chamber 2. A connecting rod 42 is fixedly provided on one side of the support plate 4. The outer end of the connecting rod 42 passes through the groove 27 of the protective chamber 2 and extends a distance to the outer area of ​​the protective chamber 2. The connecting rod 42 is provided with a thread 43. A handwheel 44 is sleeved on the connecting rod 42. The contact part of the handwheel 44 sleeved on the connecting rod 42 is provided with a thread 43 groove that matches the thread 43, so that when the handwheel 44 rotates, it can form a thread 43 engagement movement along the thread 43 on the connecting rod 42. A silicone ring 45 is fixedly provided on the side of the handwheel 44 facing the protective chamber 2.

[0037] Place the test tube rack 1 on the support plate 4 and let the bottom of the test tube rack 1 be embedded in the groove 41. Then, hold the hand wheel 44 from the outside of the protective chamber 2 and pull it upward along the vertical track groove 27. This will cause the connecting rod 42 to drive the support plate 4 to move the test tube rack 1 upward, so that the extension tube 26 at the bottom of the liquid storage tube 24 can be inserted into the test tube 11 from the corresponding test tube 11 opening. In this way, when physiological saline is added later, the physiological saline dripping from the bottom of the extension tube 26 can be closer to the test sample in the test tube 11, preventing liquid impact from splashing.

[0038] After the support plate 4 is moved upward, the handwheel 44 can be rotated to gradually approach the protective chamber 2 in a spiral shape along the thread 43 on the connecting rod 42, until the silicone ring 45 on the handwheel 44 comes into contact with the protective chamber 2. At this time, the silicone ring 45 will deform after being squeezed, increasing the contact area and contact friction with the protective chamber 2. This prevents the handwheel 44 from reversing in its natural state, thus restricting the handwheel 44 and the connecting rod 42 from moving downward, so that the support plate 4 stays in the position after being moved upward.

[0039] In a further preferred embodiment, an openable cover plate 5 is provided on the slot at the top of the protective chamber 2, and the cover plate 5 is provided with a through slot for placing the pulling plate 32; the cover plate 5 provided at the top of the protective chamber 2 can protect the top of the protective chamber 2, so that the saline in the liquid storage tube 24 will not be affected.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
