Description

Technical Field

[0001] This utility model relates to the field of vacuum blood collection tube technology, specifically a safety helmet for vacuum blood collection tubes. Background Technology

[0002] The safety cap of a vacuum blood collection tube usually refers to its cap, which plays an important role in the blood collection tube. Different colored safety caps represent different uses and types of additives in the blood collection tube. Red safety caps are used for routine serological tests; purple safety caps are used for tests such as complete blood count; and green safety caps are used for biochemical tests. Through color coding, medical staff can quickly and accurately identify the purpose of the blood collection tube and avoid confusion.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, if the vacuum blood collection tube is not sealed properly, external air, dust or microorganisms will enter the blood collection tube and contaminate the collected blood sample, which will lead to incorrect results when the sample is tested. At the same time, the blood collection tube is easily damaged by external force during transportation or storage, which may cause the blood collection tube to rupture. It cannot prevent the lid from being opened accidentally and cannot protect the safety of the vacuum blood collection tube, thus having low practicality.

[0004] To address the aforementioned problems, the inventors proposed a safety helmet for vacuum blood collection tubes. Summary of the Invention

[0005] To address the issues of insufficient sealing of vacuum blood collection tubes and inability to prevent accidental opening of the box lid, thus failing to protect the safety of vacuum blood collection tubes, the purpose of this utility model is to provide a safety cap for vacuum blood collection tubes.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a safety cap for vacuum blood collection tubes, comprising a box body, a box cover rotatably connected to the top surface of the box body, a buckling device symmetrically provided on one side of the box body and the box cover, a plurality of sealing tube assemblies arranged in a rectangular array on the inner wall of the box body, each sealing tube assembly comprising a tube body, a tube cap snapped onto the upper part of the tube body, a sealing gasket fixedly connected to the bottom surface of the tube cap, a sealing groove for use with the sealing gasket being opened on the top surface of the tube body, a limit frame fixedly connected to the upper part of the tube body, and a limit block for use with the limit frame fixedly connected to the outer surface of the tube cap.

[0007] As a preferred technical solution of this application, the buckle device includes a first fixing plate and a second fixing plate. A hook is fixedly connected to one side of the first fixing plate, a support plate is fixedly connected to one side of the second fixing plate, a connecting plate is rotatably connected to one side of the support plate, a handle is fixedly connected to the end of the connecting plate, a rotating shaft is movably passed through one side of the connecting plate, and a buckle frame is movably sleeved at the end of the rotating shaft.

[0008] With the above technical solution, the operator can rotate the connecting plate around the support plate by pulling the handle. The rotating shaft moves through the connecting plate, and the locking frame is movably sleeved on the end of the rotating shaft. When it is necessary to close the box cover, the locking frame is inserted into the inner wall of the hook to lock the box body and the box cover. When it is necessary to open the box cover, the handle is pulled to disengage the locking frame from the hook, and the box cover can be opened. Conversely, the handle is pressed down to firmly fix the box cover to the box body, which can prevent the box cover from being opened accidentally and protect the safety of the vacuum blood collection tube.

[0009] As a preferred technical solution of this application, the outer surface of the tube body is provided with anti-slip texture.

[0010] Through the above technical solution, the anti-slip texture can increase friction when the operator holds the tube, preventing the tube from falling and being damaged due to slipping.

[0011] As a preferred technical solution of this application, a sealing sleeve is fixedly connected to the bottom surface of the cap.

[0012] The sealing sleeve, which is fixedly connected to the bottom of the cap, further enhances the sealing effect through the above technical solution.

[0013] As a preferred technical solution of this application, the limiting block is made of an elastic material.

[0014] With the above technical solution, since the limiting block is made of elastic material, when the pipe cap is attached to the pipe body, the limiting block will undergo elastic deformation and pass smoothly through the limiting frame. When the pipe cap is fully clamped, the limiting block returns to its original shape and is stuck in the limiting frame to prevent the pipe cap from falling off accidentally.

[0015] As a preferred technical solution of this application, one side of the first fixing plate is fixedly connected to the box cover, and one side of the second fixing plate is fixedly connected to the box body.

[0016] Through the above technical solution, the first fixing plate and the second fixing plate can be used in a better manner.

[0017] As a preferred technical solution of this application, the outer surface of the card frame is engaged with the inner wall of the card hook.

[0018] Using the above technical solution, the lid can be opened by pulling the handle to disengage the card frame from the hook.

[0019] The technical effects of this utility model are as follows: 1. When the cap is attached to the tube body, the sealing gasket is embedded in the sealing groove to form a tight seal, preventing blood leakage and external air from entering the tube body and affecting the quality of the blood sample. Since the limiting block is made of elastic material, it will undergo elastic deformation when the cap is attached to the tube body, and pass smoothly through the limiting frame. When the cap is fully tightened, the limiting block returns to its original shape and is locked in the limiting frame, preventing the cap from accidentally falling off, thereby effectively strengthening the sealing of the vacuum blood collection tube.

[0020] 2. This utility model allows the connecting plate to rotate around the support plate by pulling the handle. The rotating shaft moves through the connecting plate, and the locking frame is movably sleeved on the end of the rotating shaft. The locking frame is then inserted into the inner wall of the hook to lock the box body and the box cover. Conversely, when it is necessary to open the box cover, the handle is pressed down to firmly fix the box cover to the box body, thereby achieving the purpose of preventing the box cover from being opened accidentally and protecting the safety of the vacuum blood collection tube.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1-5 As shown, this utility model provides a safety helmet for vacuum blood collection tubes, including a box body 1, a box cover 3 rotatably connected to the top surface of the box body 1, a buckle device 4 symmetrically provided on one side of the box body 1 and the box cover 3, and a plurality of sealing tube assemblies 2 arranged in a rectangular array on the inner wall of the box body 1. The sealing tube assembly 2 includes a tube body 21. The outer surface of the tube body 21 is provided with anti-slip texture 22. A tube cap 23 is snapped onto the upper part of the tube body 21. A sealing sleeve 24 is fixedly connected to the bottom surface of the tube cap 23. A sealing gasket 25 is fixedly connected to the bottom surface of the tube cap 23. A sealing groove 26 for use with the sealing gasket 25 is provided on the top surface of the tube body 21. A limit frame 27 is fixedly connected to the upper part of the tube body 21. A limit block 28 for use with the limit frame 27 is fixedly connected to the outer surface of the tube cap 23. The limit block 28 is made of elastic material.

[0029] When the cap 23 is attached to the tube body 21, the limiting block 28 will undergo elastic deformation and pass smoothly through the limiting frame 27. After the cap 23 is fully secured, the limiting block 28 returns to its original state and is locked in the limiting frame 27, preventing the cap 23 from accidentally falling off and effectively strengthening the seal of the vacuum blood collection tube.

[0030] The buckle device 4 includes a first fixing plate 41 and a second fixing plate 42. One side of the first fixing plate 41 is fixedly connected to the lid 3, and one side of the second fixing plate 42 is fixedly connected to the body 1. A hook 43 is fixedly connected to one side of the first fixing plate 41, and a support plate 44 is fixedly connected to one side of the second fixing plate 42. A connecting plate 45 is rotatably connected to one side of the support plate 44. A handle 46 is fixedly connected to the end of the connecting plate 45. A rotating shaft 47 is movably passed through one side of the connecting plate 45. A locking frame 48 is movably sleeved at the end of the rotating shaft 47. The outer surface of the locking frame 48 is engaged with the inner wall of the hook 43.

[0031] The card frame 48 is inserted into the inner wall of the hook 43 to lock the box body 1 and the box cover 3. When it is necessary to open the box cover 3, pull the handle 46 to disengage the card frame 48 from the hook 43 and open the box cover 3. Conversely, press down the handle 46 to firmly fix the box cover 3 to the box body 1, which can prevent the box cover 3 from being opened accidentally and protect the safety of the vacuum blood collection tube.

[0032] The working principle of the safety cap for a vacuum blood collection tube in this embodiment is as follows: The tube body 21 serves as the main body of the vacuum blood collection tube, used to contain the collected blood sample. The anti-slip texture 22 increases friction when the operator holds the tube body 21, preventing it from slipping and being damaged. It is snapped onto the upper part of the tube body 21, sealing it. The sealing gasket 25, fixedly connected to the bottom surface of the cap 23, works in conjunction with the sealing groove 26 on the top surface of the tube body 21. When the cap 23 is snapped onto the tube body 21, the sealing gasket 25 is embedded in the sealing groove 26, forming a tight seal to prevent blood leakage from the tube and external leakage. If air enters the tube body 21, it will affect the quality of the blood sample. The sealing sleeve 24 fixedly connected to the bottom of the tube cap 23 further enhances the sealing effect. The limiting frame 27 fixedly connected to the upper part of the tube body 21 and the limiting block 28 fixedly connected to the outer surface of the tube cap 23 cooperate with each other. Since the limiting block 28 is made of elastic material, when the tube cap 23 is snapped onto the tube body 21, the limiting block 28 will undergo elastic deformation and pass smoothly through the limiting frame 27. When the tube cap 23 is fully snapped, the limiting block 28 returns to its original shape and is stuck in the limiting frame 27 to prevent the tube cap 23 from accidentally falling off, thereby achieving the purpose of effectively strengthening the sealing of the vacuum blood collection tube. The operator can rotate the connecting plate 45 around the support plate 44 by pulling the handle 46. The rotating shaft 47 moves through the connecting plate 45, and the locking frame 48 is movably sleeved on the end of the rotating shaft 47. When it is necessary to close the box cover 3, the locking frame 48 is inserted into the inner wall of the hook 43 to lock the box body 1 and the box cover 3. When it is necessary to open the box cover 3, the operator can pull the handle 46 to disengage the locking frame 48 from the hook 43 and open the box cover 3. Conversely, the operator can press down the handle 46 to firmly fix the box cover 3 to the box body 1, thereby achieving the purpose of preventing the box cover 3 from being opened accidentally and protecting the safety of the vacuum blood collection tube.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
