Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a vacuum blood collection tube cap device. Background Technology

[0002] Vacuum blood collection tubes are disposable negative pressure vacuum tubes that enable quantitative blood collection. They need to be used in conjunction with intravenous blood collection needles. Vacuum blood collection tubes have the advantages of accurate blood collection, good safety performance, good separation of serum and plasma, convenient operation, and the ability to collect multiple blood samples with one needle. They are the best choice in clinical practice to replace disposable syringes for blood sample collection, and therefore, vacuum blood collection tubes are widely used.

[0003] In the production process of vacuum blood collection tubes, after the blood collection tubes are disinfected and dried, they need to be bonded with caps. The traditional manual cap bonding method is not only complicated and time-consuming, but also has a relatively high probability of defective products. Utility Model Content

[0017] 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.

[0018] According to an embodiment of the present invention, a vacuum blood collection tube cap device is provided.

[0019] Example 1:

[0020] like Figure 1-5 As shown, the vacuum blood collection tube cap device according to an embodiment of the present utility model includes a base 1 and a fixing seat 2 located on the top of the base 1. The top of the fixing seat 2 is provided with a placement groove 3 for placing the vacuum blood collection tube, and a limiting mechanism 4 for reinforcing the vacuum blood collection tube is provided in the placement groove 3. The base 1 has symmetrically arranged columns 5 on its top and on one side of the fixed base 2. A connecting plate 6 is provided on one side of the two sets of columns 5. A cap plate 7 for capping the vacuum blood collection tube is provided below the connecting plate 6. The cap plate 7 is connected to the connecting plate 6 through a reciprocating mechanism. The limiting mechanism 4 includes a fixed ring 8 and a worm gear ring 9. The fixed ring 8 and the worm gear ring 9 are provided with a plurality of symmetrically arranged sliding holes 10 at equal intervals. Two sets of sliding holes 10 are slidably connected to vertically arranged sliding rods 11. A movable block 12 is movably sleeved on the sliding rod 11 and located between the fixed ring 8 and the worm gear ring 9.

[0021] Example 2:

[0022] like Figure 1-5 As shown, the movable blocks 12 have a triangular structure at their close ends and their outer walls are in contact with each other. The ends of several movable blocks 12 are in contact to form a circular through hole 13. The fixed base 2 is laterally rotatably connected to a worm 14 that meshes with multiple sets of worm gear rings 9. One end of the worm 14 extends to the outside of the fixed base 2 and is provided with a knob 15. Both ends of the slide rod 11 are respectively provided with a limiting block 16 to prevent it from falling off. The slide hole 10 is inclined.

[0023] The circular through hole 13 is in its maximum state and matches the diameter of the placement groove 3. The vacuum blood collection tube is placed in the placement groove 3. Rotating the knob 15 drives the worm gear 14 to rotate. The worm gear 14 meshes with the worm wheel ring 9, causing the worm wheel ring 9 to rotate. During the clockwise rotation, the sliding hole 10 of the worm wheel ring 9 makes a circular motion, causing the sliding hole 10 on the worm wheel ring 9 to squeeze the sliding rod 11 to move in the same direction. The sliding rod 11 drives the movable block 12 to move in the same direction, making the circular through hole 13 formed between several movable blocks 12 smaller, thereby limiting the vacuum blood collection tube.

[0024] Example 3:

[0025] like Figure 1-5 As shown, the reciprocating mechanism includes a housing 17 located on the side of the connecting plate 6. A connecting member 18 extending outward and connected to the cap plate 7 is vertically movably connected inside the housing 17. A double-sided rack 19 is provided at the top of the connecting member 18. Sector gears 20 meshing with the double-sided rack 19 are symmetrically provided on both sides of the rack. The two sets of sector gears 20 are movably connected to the housing 17 through rotating shafts. Driven gears 21 are sleeved on the two sets of rotating shafts. A transmission gear 22 meshing with the two sets of driven gears 21 is rotatably connected to one side of the housing 17. The transmission gear 22 is movably connected to the housing 17 through a drive shaft. A motor 23 for driving the transmission gear 22 to rotate is provided inside the housing 17. A sliding sleeve 24 movably sleeved on the connecting member 18 is also provided inside the housing 17.

[0026] The starter motor 23 drives the transmission gear 22 to rotate. The transmission gear 22 meshes with two sets of driven gears 21, which in turn drive two sets of sector gears 20 to rotate in both directions. During the rotation, the two sets of sector gears 20 alternately mesh with the double-sided rack 19, which drives the cap plate 7 to reciprocate through the connector 18, ultimately combining the blood collection tube cap with the vacuum blood collection tube.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, the circular through-hole 13 is in its maximum state and matches the diameter of the placement groove 3. The vacuum blood collection tube is placed in the placement groove 3, and the knob 15 is rotated to drive the worm 14 to rotate. The worm 14 meshes with the worm wheel ring 9, causing the worm wheel ring 9 to rotate. During the clockwise rotation of the worm wheel ring 9, its sliding hole 10 makes a circular motion, causing the sliding hole 10 on the worm wheel ring 9 to press the slide rod 11 to move in the same direction. The slide rod 11 drives the movable block 12 to move in the same direction, so that the circular shape formed between the several movable blocks 12... The through hole 13 becomes smaller, thereby limiting the vacuum blood collection tube; then the motor 23 is started to drive the transmission gear 22 to rotate. The transmission gear 22 meshes with two sets of driven gears 21 respectively, so that the two sets of driven gears 21 drive two sets of sector gears 20 to perform forward and reverse motion. During the rotation, the two sets of sector gears 20 alternately mesh with the double-sided rack 19, so that the double-sided rack 19 drives the cap plate 7 to reciprocate through the connector 18, and finally combines the blood collection tube cover with the vacuum blood collection tube.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, a mechanized structure is adopted, replacing the original manual operation, which greatly shortens the processing time, improves the product qualification rate, and significantly reduces labor costs. The setting of the limiting mechanism 4 can limit the vacuum blood collection tube placed in the placement groove 3, preventing the test tube from shifting when the vacuum blood collection tube cap is closed, further improving the product qualification rate. The setting of the reciprocating mechanism can drive the cap plate 7 to reciprocate up and down, which can prevent the cap plate 7 from exceeding the safe range of movement during the movement, thereby preventing the blood collection test tube from breaking and avoiding potential hazards to personal safety.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
