[0002] When hospitals examine patients, blood sampling is one of the commonly used methods. After the blood is sampled, it is collected and stored using a glass sampling tube, and then transported to the testing equipment for testing.

[0003] Through patent search, it is found that a portable blood sampling tube with publication number CN213189618U includes a tube body, a blocking device is fastened at the opening of the tube body, the outer end of the blocking device is located on the outside of the tube body and is fixedly connected to a pressure pad, the outer end of the pressure pad is fixedly connected to a cover plate, the outer side of the tube body is provided with a protective sleeve, the outer side of the protective sleeve is slidably connected to four groups of sliders that are symmetrically distributed, and two groups are rotatably connected between the sliders. A locking ring is connected. In the utility model, the blocking device is inserted into the opening of the tube body, and then the locking ring is rotated to rotate the tail end of the locking ring to the upper side of the cover plate, and then the slider is pushed to slide along the slide groove. When the limiter is tightly fitted with the blocking pad, the slider can be locked. At this time, the locking ring is buckled into the buckle groove inside the cover plate to complete the sealing and tightening of the opening end of the tube body, preventing the blocking device from falling off the tube body and causing the blood sample to be lost during the process of carrying the tube body by medical personnel.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 to Figure 6 As shown, a portable blood sampling tube includes a protective shell 1 and a protective shell 2 which are symmetrically arranged. A placement port 3 is provided on the adjacent side of the protective shell 1 and the protective shell 2. A sampling tube 4 is provided between the two placement ports 3, and a cap 5 is provided on the top of the sampling tube 4. An elastic pad 1 8 is fixedly connected to the adjacent side of the protective shell 1 and the protective shell 2. An elastic pad 2 9 is fixedly connected to the top of the cap 5. The design of the elastic pad 1 8 and the elastic pad 2 9 strengthens the protection of the sampling tube 4 when it is impacted. An adjustment mechanism 6 is provided between the protective shell 1 and the protective shell 2;

[0026] The adjustment mechanism 6 includes a set of adjustment plates 61 fixedly connected to the front and rear ends of the side of the protective shell 1 close to the protective shell 2 2, and a set of grooves 62 are provided at the front and rear ends of the side of the protective shell 2 close to the protective shell 1, and the ends of the adjustment plates 61 extend into the grooves 62. The inner sides of the grooves 62 are fixedly connected to the limiting rods 10, and the side of the adjustment plates 61 close to the spring 1 63 is provided with limiting grooves 11, and the limiting rods 10 are slidably connected to the limiting grooves 11, which play a role in limiting the adjustment plates 61 and will not be skewed. One end of the adjustment plate 61 located in the groove 62 is fixedly connected to a spring 1 63, and the other end of the spring 1 63 is fixedly connected to the inner side of the groove 62. Slide grooves 64 are provided on the front and rear sides of the top of the protective shell 2, and the slide grooves 64 are connected to the grooves 62. Pressing rods 67 are slidably connected in the slide grooves 64. The bottom ends of the pressing rods 67 are fixedly connected to spring 2 68, and the bottom ends of the spring 2 68 are fixedly connected to the bottom ends of the slide grooves 64. A group of arc-shaped pieces 65 are fixedly connected to the top of the adjustment plate 61. A notch 66 is provided at the bottom end of the arc-shaped pieces 65 away from the sampling tube 4. A group of blocks 69 are fixedly connected to the side of the pressing rod 67 close to the sampling tube 4.

[0027] During operation, the protective shell 1 and the protective shell 2 are pulled toward both sides, and the spring 1 63 is stretched. At this time, the adjusting plate 61 slides toward the outer side of the groove 62, and the adjusting plate 61 drives the arc-shaped piece 65 to move. The arc-shaped piece 65 is squeezed by the stopper 69 and deformed. After passing the stopper 69, it returns to its original state, and the space between the two receiving ports 3 between the protective shell 1 and the protective shell 2 is stretched to the maximum. At this time, under the action of the restoring force of the spring 1 63, the stopper 69 resists the arc-shaped piece 65, and at this time, the size of the two receiving ports 3 between the protective shell 1 and the protective shell 2 is restricted and fixed, and then the sampling tube 4 is placed between the two receiving ports 3, and the pressing rod 67 is pressed downward, and the pressing rod 67 moves the spring 2 68 downward, and the spring 2 68 is squeezed, and at the same time, the pressing rod 67 drives the stopper 69 to move downward, and the stopper 69 moves to contact the top of the adjustment plate 61, and the stopper 69 just corresponds to the notch 66. At this time, under the action of the spring 1 63, the adjustment plate 61 slides into the groove 62 again, and the stopper 69 passes through the corresponding notch 66 until the two protective shells 1 and 2 clamp the sampling tube 4. The pressing rod 67 is released, and the stopper 69 is reset. At this time, the stopper 69 is against the corresponding arc-shaped piece 65, reducing the extrusion force on the sampling tube 4 to avoid the sampling tube 4 being crushed. At this time, the sampling tube 4 is clamped and fixed, and then the structure can adjust the size of the placement port 3 between the protective shell 1 and the protective shell 2, so that it can be suitable for sampling tubes 4 of different diameters, which greatly improves the practicality of the device.

A U-shaped handle 12 is provided on the side away from the two sliding rods 72, and the ends of the U-shaped handle 12 are rotatably connected to the sliding rod 72. The design of the U-shaped handle 12 is convenient for carrying and taking the device, and at the same time, the U-shaped handle 12 can be slid to drive the two sliding rods 72 to move at the same time. The bottom ends of the pressure plates 77 are fixedly connected to the limiting rods 13, and the bottom ends of the limiting rods 13 extend to the bottom of the fixed frame 74. The design of the limiting rods 13 limits the movement of the pressure plates 77 so that they can only slide up and down.

[0029] When working, cover cap 5 is covered on the top of protective shell 1 1 and protective shell 2, and slide rod 72 is slid so that slide rod 72 corresponds to perforation 75, slide rod 72 enters perforation 75, and then presses down cover cap 5, slide rod 72 presses down pressure plate 77, pressure plate 77 squeezes spring three 76, and then slides slide rod 72 again to make it correspond to slot 78, release cover cap 5, under the action of spring three 76, pressure plate 77 squeezes slide rod 72 into slot 78, at this time, the fixation of cover cap 5 is realized, and when the distance between protective shell 1 and protective shell 2 becomes longer due to the larger diameter of the placed sampling tube 4, slide rod 72 first enters side opening 73, and then enters perforation 75 again. Through the design of side opening 73, no matter how protective shell 1 and protective shell 2 change, cover cap 5 can always be fixed to them, and the top of sampling tube 4 can be prevented from being hit and broken, thereby achieving the protective effect.

At this time, under the action of the restoring force of the spring 1 63, the stopper 69 resists the arc-shaped piece 65, and the size of the two receiving ports 3 between the protective shell 1 and the protective shell 2 2 is limited and fixed, and then the sampling tube 4 is placed between the two receiving ports 3, and the pressing rod 67 is pressed downward, and the pressing rod 67 moves the spring 2 68 downward, and the spring 2 68 is squeezed, and the pressing rod 67 is pressed at the same time. 67 drives the stopper 69 to move downward, and the stopper 69 moves to contact the top of the adjustment plate 61, and the stopper 69 just corresponds to the notch 66. At this time, under the action of the spring 1 63, the adjustment plate 61 slides into the groove 62 again, and the stopper 69 passes through the corresponding notch 66 until the two protective shells 1 and 2 clamp the sampling tube 4. The pressing rod 67 is released, and the stopper 69 is reset. At this time, the stopper 69 is against the corresponding arc-shaped piece 65, reducing the extrusion force on the sampling tube 4 to avoid the sampling tube 4 being crushed.
