[0018] The beneficial effects of the present invention are:

[0019] 1. The sliding rectangular block slides in the sliding cavity to drive the blood collection tube body to descend. However, the sliding rectangular block compresses the compression spring while descending. After being compressed to the specified position, the compression spring begins to rebound. During the rebound and compression process, the blood in the blood collection tube body is driven to shake, so that the blood itself is always in an active state. In addition, the set limit frame can prevent the sliding rectangular block from shaking too much and causing the blood collection tube body to fall off, thereby improving the blood collection effect of the vacuum blood collection tube and the use effect of the device.

[0020] 2. To prevent the blood collection tube body from being damaged due to collision during placement, the elastic force of the first tension spring drives the two groups of first buffer clamps to limit the bottom of the outer wall of the blood collection tube body, and then pushes the sliding clamping column again to clamp into a specified group of clamping cavities for clamping and limiting. The reverse thrust of the two groups of tension springs ensures that the blood collection tube itself will not be damaged when it is hit or shaken, thereby improving the safety of blood collection tube placement.

[0021] 3. The blood is collected by connecting the venous blood collection needle through the liquid inlet tube, and the blood is collected into the blood collection tube body. Then, the condensation structure is connected through the air supply tube, so that the condensed gas enters the storage tube. Then, the air supply tube is sealed by the sealing shell, and the blood in the blood collection tube is cooled and protected by the condensed gas placed in the storage tube, which prolongs the storage time and improves the quality of blood collection.

[0022] 4. Drive the connecting tube to slide in the connecting tube, and drive the two groups of second buffer clamps connected to the connecting tube to move in opposite directions. During the movement, the two groups of second tension springs are squeezed, and then the blood collection tube body is fitted with the clamping groove, and then the pulling of the tension handle is released. Then, when the second tension spring senses that the pressure disappears, it starts to rebound. During the rebound process, the two groups of second buffer clamps are driven to move in the direction close to the blood collection tube body, and the blood collection tube is limited and stabilized, thereby improving the limiting stabilization effect and the separation effect of the blood collection tube.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present invention provides a detachable contact-free vacuum blood collection tube. It includes an active placement component 1, exemplarily, such as Figure 1 and Figure 2 As shown, the top of the active placement component 1 is movably connected to the convenient component 2, the top of the convenient component 2 is installed with a moving component 3, the top of the moving component 3 is installed with a sealing cover component 4, the bottom of the sealing cover component 4 is connected to the blood collection tube body 5, and two groups of separate and disassembled components 6 are symmetrically installed on the outer wall of the sealing cover component 4.

[0036] For example, Figure 3 and Figure 4As shown, the active placement component 1 includes a placement plate 101, a fixed plate 102 is installed at the top edge of the placement plate 101, a sliding cavity 103 is opened on one side wall of the fixed plate 102, a mounting block 104 is installed on the bottom inner wall of the fixed plate 102, a connecting rod 105 is installed on the top of the mounting block 104, a stopper 106 is installed on the top of the connecting rod 105, a compression spring 107 is installed on the top of the mounting block 104, the compression spring 107 is sleeved on the outer wall of the connecting rod 105, the top of the compression spring 107 is connected to a sliding rectangular block 108, the sliding rectangular block 108 is slidably sleeved on the outer wall of the connecting rod 105, the sliding The outer wall of the rectangular block 108 slides and fits in the sliding cavity 103, and a first magnetic block 109 is installed on the top of the sliding rectangular block 108. A side wall of the fixed plate 102 away from the sliding cavity 103 is rotatably connected to a rotating frame 110, and a second magnetic block 111 is installed at the bottom of the rotating frame 110. The first magnetic block 109 is magnetically connected to the second magnetic block 111. A limiting frame 112 is installed on a side wall of the fixed plate 102 close to the sliding cavity 103, and the limiting frame 112 is located directly above the sliding rectangular block 108. A fixing ring 113 is installed on one side wall of the sliding rectangular block 108, and a plurality of groups of snap-in holes 114 are opened in a circular array on the top of the fixing ring 113.

[0037] The clamping rod 202 provided at the bottom of the placing tube 201 is movably clamped with the clamping hole 114 opened at the top of the fixing ring 113. When the blood collection tube body 5 is performing blood collection, the first magnetic block 109 and the second magnetic block 111 are in a magnetic state, so that the blood collection tube body 5 on the sliding rectangular block 108 will not shake. When the blood collection is completed and the blood is transported, the rotating frame 110 is started to drive the second magnetic block 111 to rotate, so that the first magnetic block 109 and the second magnetic block 111 are in a demagnetized state. Subsequently, during the transportation process, the sliding rectangular block 108 slides in the sliding cavity 103, thereby driving the blood collection tube body 5 to descend. However, the sliding rectangular block 108 is also lowered while descending. The compression spring 107 will be compressed, and after being compressed to the specified position, the compression spring 107 begins to rebound, and the blood in the blood collection tube body 5 is driven to shake during the rebound and compression process, so that the blood itself is always in an active state, and a limit frame 112 is arranged directly above the sliding rectangular block 108, so as to avoid the problem that the blood collection tube body 5 falls off due to excessive shaking of the sliding rectangular block 108. In addition, in order to prevent shaking and damage during the transportation of conventional blood collection tubes, the blood collection tubes are protectively wrapped. Although this improves the protective effect, it cannot guarantee that the collected blood is always in an active and active state, which improves the blood collection effect of the vacuum blood collection tube and improves the use effect of the device.

[0038] For example, Figure 5As shown, the convenient component 2 includes a placement tube 201, and a plurality of groups of clamping rods 202 are distributed in a circular array at the bottom of the placement tube 201. The clamping rods 202 are movably clamped with the clamping holes 114, and two groups of first fixed blocks 203 are symmetrically installed on the inner wall of the placement tube 201, and a group of sleeve tubes 204 are installed on one side wall of each group of the first fixed blocks 203, and a group of sliding rods 205 are slidably connected in each group of the sleeve tubes 204, and a group of first buffer clamps 206 are installed on one side wall of each group of the sliding rods 205, and two groups of first tension springs 207 are symmetrically installed on the edge of one side wall of each group of the first fixed blocks 203 near the sleeve tube 204, and the other end of each group of the first tension springs 207 is installed on the first buffer clamp 206.

[0039] For example, Figure 6 As shown, the moving component 3 includes a mounting tube 301, a sliding tube 302 is slidably connected inside the mounting tube 301, a plurality of groups of snap-in cavities 303 are evenly spaced on the outer wall of the sliding tube 302, the bottom of the sliding tube 302 is mounted on the top of the placement tube 201, a second fixed block 304 is mounted on the outer wall of the mounting tube 301, a sliding snap-in column 305 is slidably connected to the second fixed block 304, and the sliding snap-in column 305 is movably snap-in with the snap-in cavity 303.

[0040] In order to prevent the blood collection tube body 5 from being damaged by collision during the placement process, the two groups of first buffer clamps 206 are first pulled to move in opposite directions, and the sliding rod 205 is driven to slide in the sleeve tube 204 during the movement. During the sliding process, pressure is provided to the two groups of first tension springs 207, and then the placement tube 201 is pushed to move upward, and the sliding tube 302 is driven to slide in the installation tube 301 during the movement. When the placement tube 201 rises to the specified position, the pulling of the two groups of first buffer clamps 206 is released, and then the elastic force of the first tension spring 207 drives the two groups of first buffer clamps 206 to limit the bottom of the outer wall of the blood collection tube body 5, and then the sliding clamping column 305 is pushed again to clamp into the specified group of clamping cavities 303 for clamping and limiting. The reverse thrust of the two groups of tension springs ensures that the blood collection tube itself will not be damaged when it is hit or shaken, thereby improving the safety effect of blood collection tube placement.

[0041] For example, Figure 7As shown, the sealing cover assembly 4 includes a sealing cover structure 401, a protective ring 405 is installed at the bottom edge of the sealing cover structure 401, the top of the mounting tube 301 is installed on the bottom of the protective ring 405, and a clamping groove is opened at the bottom of the sealing cover structure 401; the blood collection tube body 5 is movably clamped in the clamping groove, and the top center of the sealing cover structure 401 is connected to an air supply pipe 402, the top of the air supply pipe 402 is rotatably connected to a sealing shell 403, the bottom of the air supply pipe 402 is connected to a storage tube 406, and the top of the sealing cover structure 401 is connected to a liquid inlet pipe 404, and the output end of the liquid inlet pipe 404 is located in the blood collection tube body 5.

[0042] The blood collection tube with the sealing cover structure 401 is pre-evacuated to different vacuum degrees, and then connected to the venous blood collection needle through the liquid inlet tube 404 for blood collection, and the blood is collected into the blood collection tube body 5. Then, the condensation structure is connected through the gas supply tube 402, so that the condensed gas enters the storage tube 406, and then the gas supply tube is sealed by the sealing shell 403. The condensed gas placed in the storage tube 406 is used to cool the blood in the blood collection tube, thereby extending the storage time and improving the quality of blood collection.

[0043] For example, Figure 8 As shown, the separation and disassembly component 6 includes a connecting tube 601, the outer wall of each group of the connecting tubes 601 is installed on the protective ring 405, a group of sleeved rectangular plates 602 are sleeved on the outer wall of each group of the connecting tubes 601, each group of the sleeved rectangular plates 602 are installed on the inner wall of the protective ring 405, a group of connecting tubes 603 are slidably connected to the inner wall of each group of the connecting tubes 601, a group of second buffer clamps 604 are installed on one side wall of each group of the connecting tubes 603, two groups of second tension springs 605 are symmetrically installed on one side wall of each group of the second buffer clamps 604 close to the sleeved rectangular plate 602, the other end of each group of the second tension springs 605 is installed on the sleeved rectangular plate 602, a group of rotating rings 606 are rotatably connected to one side wall of each group of the connecting tubes 603 away from the second buffer clamps 604, and a group of stretching handles 607 are installed on one side wall of each group of the rotating rings 606 away from the connecting tubes 603.

[0044] In order to improve the separation stability effect of the device, the thumb and the middle finger are first placed in one of the stretching handles 607 respectively, and then stretched outward. During the stretching process, the connecting tube 603 is driven to slide in the connecting tube 601, and the two groups of second buffer clamps 604 connected to the connecting tube 603 are driven to move in opposite directions. During the movement, the two groups of second stretching springs 605 are squeezed, and then the blood collection tube body 5 is fitted with the clamping groove, and then the pulling of the stretching handle 607 is released. Then, when the second stretching spring 605 senses the disappearance of pressure, it begins to rebound. During its rebound process, the two groups of second buffer clamps 604 are driven to move in the direction close to the blood collection tube body 5, and limit and stabilize it, thereby improving the limit and stability effect while improving the separation effect of the blood collection tube.

[0045] The sliding rectangular block 108 slides in the sliding cavity 103 to drive the blood collection tube body 5 to descend. However, the sliding rectangular block 108 will compress the compression spring 107 while descending. After being compressed to the specified position, the compression spring 107 begins to rebound. During the rebound and compression process, the blood in the blood collection tube body 5 is driven to shake, so that the blood itself is always in an active state. In addition, the set limit frame 112 can prevent the sliding rectangular block 108 from shaking too much and causing the blood collection tube body 5 to fall off, thereby improving the blood collection effect of the vacuum blood collection tube and improving the use effect of the device.

[0046] In order to prevent the blood collection tube body 5 from being damaged due to collision during placement, the elastic force of the first tension spring 207 drives the two groups of first buffer clamps 206 to limit the bottom of the outer wall of the blood collection tube body 5, and then pushes the sliding clamping column 305 again to clamp into a specified group of clamping cavities 303 for clamping and limiting. The reverse thrust of the two groups of tension springs ensures that the blood collection tube itself will not be damaged when it is hit or shaken, thereby improving the safety of blood collection tube placement.

[0047] Blood is collected by connecting the venous blood collection needle through the liquid inlet tube 404 and collecting the blood into the blood collection tube body 5. Subsequently, the condensation structure is connected through the gas supply tube 402 so that the condensed gas enters the storage tube 406. Subsequently, the gas supply tube is sealed by the sealing shell 403. The condensed gas placed in the storage tube 406 is used to cool the blood in the blood collection tube, thereby extending the storage time and improving the quality of blood collection.

[0048] The connecting tube 603 is driven to slide in the connecting cylinder 601, and the two groups of second buffer clamps 604 connected to the connecting tube 603 are driven to move in opposite directions. During the movement, the two groups of second tension springs 605 are squeezed, and then the blood collection tube body 5 is fitted with the clamping groove, and then the pulling of the tension handle 607 is released. Then, when the second tension spring 605 senses the disappearance of the pressure, it begins to rebound. During the rebound process, the two groups of second buffer clamps 604 are driven to move in the direction close to the blood collection tube body 5, and the blood collection tube body is limited and stabilized, thereby improving the limiting stabilization effect and the separation effect of the blood collection tube.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
