Description

Technical Field

[0001] This utility model relates to the field of blood collection tube cap technology, specifically a quick-sealing blood collection tube cap device. Background Technology

[0002] The inner wall of the blood collection tube is coated with different types of anticoagulants (such as EDTA, heparin, sodium citrate, etc.) or coagulants to meet the needs of different test items. After each use, the blood collection tube needs to be sealed with the matching cap.

[0003] The existing technical solution has at least the following drawbacks: After testing, existing blood collection tubes are typically closed manually one by one. However, this manual method is inefficient and cannot achieve rapid sealing of multiple blood collection tube caps to ensure sample safety, thus requiring improvement. Therefore, we propose a rapid-sealing blood collection tube cap device. Utility Model Content

[0004] The purpose of this invention is to provide a quick-sealing blood collection tube cap device, which solves the problem mentioned in the background art that the manual method is inefficient and cannot achieve quick sealing of multiple blood collection tube caps to ensure sample safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-sealing blood collection tube cap device, comprising a support frame, a blood collection tube frame movably mounted on the lower end of the support frame, hydraulic cylinders fixedly mounted on both sides of the support frame, a fixing frame mounted on the output end of the hydraulic cylinders, a sealing plate fixedly mounted on the lower end of the fixing frame, multiple annular airbags bonded to the lower end of the sealing plate, strip grooves formed on both sides of the support frame, fixing strips provided in the inner cavity of the strip grooves, air storage bags bonded to the upper end of the fixing strips, pressure blocks fixedly mounted on both ends of the fixing frame, sliding grooves formed at both ends of the inner cavity of the strip grooves, and sliders fixedly mounted on both ends of the fixing strips.

[0006] By adopting the above technical solution, the cap can be surrounded and limited by the annular airbag and the rubber sheet. Then, the hydraulic cylinder is opened, and the hydraulic cylinder drives the fixing frame to move downward. The fixing frame drives the sealing plate to move accordingly, causing the sealing plate to move the cap downward. In the initial downward movement, the pressure block on the fixing frame will squeeze the air storage bag, and the air in the air storage bag will be discharged into the annular airbag through the hose. The annular airbag inflates and expands, which in turn drives the rubber sheet to press and limit the cap, further ensuring the stability of the cap during sealing. After the pressure of the pressure block on the air storage bag exceeds the elastic force of the support spring, the pressure block can drive the fixing strip to slide downward. At this time, the sealing plate drives the multiple caps after limitation to quickly seal at the edge of the blood collection tube, thereby improving the sealing efficiency of multiple blood collection tubes and ensuring sample safety.

[0007] Optionally, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0008] By adopting the above technical solution, the stability of the movement of the fixed strip can be guaranteed by the cooperation of the slider and the groove.

[0009] Optionally, a rubber sheet is bonded to the inner side of the annular airbag, and the rubber sheets are arranged symmetrically.

[0010] By adopting the above technical solution, the rubber sheet can be used to surround and confine the cover through friction.

[0011] Optionally, the air outlet of the air reservoir is connected to a flexible hose, and the end of the flexible hose is connected to the air inlet of the annular air bladder.

[0012] By adopting the above technical solution and using the hose, the air inside the air reservoir can be guided.

[0013] Optionally, a support spring is fixedly installed at the lower end of the fixing strip, and the other end of the support spring is fixedly connected to the lower end of the inner cavity of the strip groove.

[0014] By adopting the above technical solution and setting the support spring, the fixing bar can be supported, which facilitates the pressure block to squeeze and vent the air storage bag.

[0015] Optionally, the pressure block is positioned above the fixing strip.

[0016] By adopting the above technical solution and setting the pressure block, the air storage bag above the fixing strip can be squeezed.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] This technical solution utilizes a support frame, blood collection tube holder, hydraulic cylinder, sealing plate, air reservoir, support spring, and slider. The cap is enclosed and secured by the annular air reservoir and its rubber sheet. Opening the hydraulic cylinder moves the fixing frame downwards, which in turn moves the sealing plate, causing the cap to move downwards. Initially, the pressure block on the fixing frame compresses the air reservoir, expelling air from the reservoir into the annular air reservoir through a hose. The annular air reservoir inflates, further pressing the rubber sheet against the cap, ensuring stability during sealing. Once the pressure of the pressure block on the air reservoir exceeds the spring force of the support spring, the pressure block slides the fixing strip downwards. At this point, the sealing plate quickly seals multiple caps at the opening of the blood collection tubes, improving sealing efficiency and ensuring sample safety. Attached Figure Description

[0024] Please see Figure 1-3 This utility model provides a technical solution: a quick-sealing blood collection tube cap device, including a support frame 1, a blood collection tube frame 11 movably mounted on the lower end of the support frame 1, hydraulic cylinders 12 fixedly mounted on both sides of the support frame 1, a fixing frame 13 mounted on the output end of the hydraulic cylinders 12, a sealing plate 14 fixedly mounted on the lower end of the fixing frame 13, multiple annular airbags 2 bonded to the lower end of the sealing plate 14, strip grooves 3 opened on both sides of the support frame 1, fixing strips 23 provided in the inner cavity of the strip grooves 3, air storage bags 22 bonded to the upper end of the fixing strips 23, pressure blocks 24 fixedly mounted on both ends of the fixing frame 13, and sliding grooves 5 opened on both ends of the inner cavity of the strip grooves 3. Both ends of the fixed strip 23 are fixedly installed with sliders 6. The air outlet of the air reservoir 22 is connected to a hose 25. The end of the hose 25 is connected to the air inlet of the annular air reservoir 2. The hose 25 can guide the air in the air reservoir 22. The lower end of the fixed strip 23 is fixedly installed with a support spring 4. The other end of the support spring 4 is fixedly connected to the lower end of the inner cavity of the strip groove 3. The support spring 4 can support the fixed strip 23, which facilitates the pressure block 24 to squeeze the air reservoir 22 to release air. The pressure block 24 is set above the fixed strip 23. The pressure block 24 can squeeze the air reservoir 22 above the fixed strip 23.

[0025] The size of the slider 6 is adapted to the size of the slide groove 5, and the slider 6 and the slide groove 5 are slidably connected. The stability of the movement of the fixed strip 23 can be guaranteed by the cooperation between the slider 6 and the slide groove 5.

[0026] A rubber sheet 21 is bonded to the inner side of the annular airbag 2, and the rubber sheets 21 are symmetrically arranged. Through the arrangement of the rubber sheets 21, the cover can be surrounded and limited by the friction of the rubber sheets 21.

[0027] During sealing, the multiple blood collection tubes to be sealed are first placed into the blood collection tube holder 11, and then the corresponding caps are placed into the annular air bladder 2. The caps are then surrounded and restricted by the rubber sheet 21 of the annular air bladder 2. Then, the hydraulic cylinder 12 is opened, and the hydraulic cylinder 12 drives the fixing frame 13 to move downward. The fixing frame 13 drives the sealing plate 14 to move accordingly, causing the sealing plate 14 to move the caps downward. In the initial downward state, the pressure block 24 on the fixing frame 13 will squeeze the air storage bladder 22, and the air in the air storage bladder 22 will be discharged into the annular air bladder 2 through the hose 25. The annular air bladder 2 will inflate and expand, thereby driving the rubber sheet 21 to press and restrict the caps, further ensuring the stability of the caps during sealing. When the pressure of the pressure block 24 on the air storage bladder 22 is greater than the elastic force of the support spring 4, the pressure block 24 drives the fixing strip 23 to slide downward. At this time, the sealing plate 14 drives the multiple caps after restriction to quickly seal at the edge of the blood collection tube, thereby improving the sealing efficiency of multiple blood collection tubes and ensuring sample safety.
