[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a sterile vacuum blood collection tube, including a tube body 1 and a tube cover 3, the inner surface of the tube cover 3 is threadedly connected to the outer surface of the tube body 1, a first rubber plug 2 is arranged near the top of the inner surface of the tube body 1, a second rubber plug 4 is arranged near the top of the inner surface of the tube cover 3, a first support seat 8 is symmetrically fixedly connected to the inner surface of the tube cover 3 near the lower side of the second rubber plug 4, a first spring 9 is symmetrically fixedly connected to the outer surface of the first support seat 8, a first clamping block 10 is fixedly connected between the end surfaces of the two first springs 9, an alcohol cotton block 11 is arranged on the inner surface of the first clamping block 10, and the inner surface of the tube body 1 is near the bottom of the second rubber plug 4. A limit ring 7 is fixedly connected to the bottom position, the limit ring 7 is located on the upper side of the tube body 1, two alcohol cotton blocks 11 are in a fitted state, the outer surface of the alcohol cotton block 11 is wrapped with a film layer, the inner surface of the tube cover 3 is symmetrically fixedly connected with a second support seat 12 near the lower side of the first support seat 8, the outer surface of the second support seat 12 is symmetrically fixedly connected with a second spring 13, a second clamping block 14 is fixedly connected between the end faces of the two second springs 13, a Velcro hook surface 15 is adhered to the inner surface of the second clamping block 14, and an absorbent cotton ball 16 is arranged on the inner surface of the second clamping block 14, and the two absorbent cotton balls 16 are in a fitted state.

[0023] The effect achieved by the entire embodiment 1 is that when blood is collected, the needle is inserted into the tube body 1 through the tube cover 3 to perform bloodletting. By setting the second rubber plug 4 on the outermost side of the tube cover 3, the inside of the tube cover 3 can be kept in a sealed and sterile state. After the needle passes through the second rubber plug 4 and enters the tube cover 3, the needle will pass between the alcohol cotton blocks 11 on both sides. By utilizing the rebound force of the first springs 9 on both sides, the alcohol cotton blocks 11 on both sides can be kept in a close contact state. By setting a film wrapped around the outside of the alcohol cotton blocks 11, alcohol evaporation can be avoided. When the needle passes between the two alcohol cotton blocks 11, the alcohol cotton blocks 11 can be placed in a sealed state. When the needle is inserted between the two absorbent cotton balls 16, the film will be scratched so that alcohol will overflow and be smeared on the surface of the needle, thereby completing the disinfection and sterilization of the needle surface. The needle is then inserted between the two absorbent cotton balls 16, and the resilience of the second spring 13 can make the absorbent cotton ball 16 completely wrap the needle to complete wiping and absorbing water from the needle. The Velcro hook surface 15 can be set to fix and limit the absorbent cotton ball 16 to prevent the absorbent cotton ball 16 from being dislocated by the needle. After the needle is inserted through the tube cover 3 to complete sterilization and wiping and absorbing water, it is inserted into the tube body 1 through the first rubber stopper 2 to perform bloodletting, thereby completing the blood collection operation.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, fixing rods 5 are symmetrically fixedly connected to the top of the tube cover 3 , and a positioning ring 6 is fixedly connected between the two fixing rods 5 . The positioning ring 6 is located at the center of the tube cover 3 .

[0025] The effect achieved by the entire embodiment 2 is that when the needle is inserted into the tube body 1 for bloodletting, the needle is inserted from the inner side of the positioning ring 6. The positioning ring 6 can be set to position the insertion position of the needle, so that the needle is inserted into the tube cover 3 in a centered position. This makes it easier for the needle to maintain a centered position and fully contact with the alcohol cotton blocks 11 and absorbent cotton balls 16 on both sides to complete sterilization, thereby improving the sterilization effect on the needle.

[0026] Working principle: When collecting blood, insert the needle through the tube cover 3 into the tube body 1 for bloodletting. By setting the second rubber plug 4 on the outermost side of the tube cover 3, the inside of the tube cover 3 can be kept in a sealed and sterile state. After the needle passes through the second rubber plug 4 and enters the tube cover 3, the needle will pass between the alcohol cotton blocks 11 on both sides. By utilizing the rebound force of the first springs 9 on both sides, the alcohol cotton blocks 11 on both sides can be kept in a close contact state. By setting a film wrapped around the outside of the alcohol cotton blocks 11, the evaporation of alcohol can be avoided. When the needle is inserted between the two alcohol cotton blocks 11, the film will be scratched so that the alcohol will overflow and be smeared on the surface of the needle, thus completing the disinfection and sterilization of the needle surface. Then the needle is inserted between the two absorbent cotton balls 16. By utilizing the second spring 13 The rebound force can make the absorbent cotton ball 16 completely wrap the needle to complete the wiping and absorbing water from the needle. The setting of the Velcro hook surface 15 can play a fixed and limited role on the absorbent cotton ball 16 to prevent the absorbent cotton ball 16 from being dislocated by the needle. After the needle is inserted through the tube cover 3 to complete sterilization and wiping and absorbing water, it is inserted into the tube body 1 through the first rubber stopper 2 to complete blood drawing. When the needle is inserted into the tube body 1 for blood drawing, the needle is inserted from the inner side of the positioning ring 6. The setting of the positioning ring 6 can play a positioning role on the insertion position of the needle, so that the needle is kept in the center position when inserted into the tube cover 3, which can facilitate the needle to maintain the center position and fully contact with the alcohol cotton blocks 11 and the absorbent cotton balls 16 on both sides to complete sterilization, thereby improving the sterilization effect on the needle.
