Description

Technical Field

[0001] This invention relates to the field of blood sample collection container technology, and in particular to a disposable human arterial blood sample collection container. Background Technology

[0002] When collecting blood samples, medical staff first clean and disinfect their hands. Because the gripping part of the needle is flat, it is inconvenient for medical staff to handle, especially when inserting the needle into the blood sample collection container. It is easy for the needle to slip out of their hands. At the same time, the sealing block on the blood sample collection container is relatively thick, requiring medical staff to forcefully insert it. If the operation is not done properly, it is easy to pull out the needle from the patient's arm, causing inconvenience to the blood sample collection. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a disposable human arterial blood sample collection container. This invention uses an auxiliary needle insertion mechanism to assist in the insertion of the blood-drawing needle, making it easier for staff to insert the needle into the tube and avoiding situations where the needle is slipped or pulled off along with the patient's arm. A detection mechanism identifies the person handling the tube, and if the person is forcibly handled, a leak-proof mechanism will inject other liquids into the blood sample to damage the blood sample and prevent leakage and cleanup.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution:

A clamping plate is fixedly connected to the telescopic ends of the telescopic rods and springs, and a sliding groove is provided on the clamping plate. A limiting plate is slidably connected in the sliding groove of one of the clamping plates.

[0009] The corner of the clamping plate on the adjacent side of the top is chamfered, and the two ends of the upper surface of the clamping plate are respectively provided with circular through grooves.

The telescopic ends of the telescopic rods 403 and springs 404 are fixedly connected to the clamping plate 406. The clamping plate 406 is provided with a sliding groove. A limiting plate 405 is slidably connected in the sliding groove of one of the clamping plates 406.

[0026] The corner of the clamping plate 406 adjacent to the top is chamfered, and the two ends of the upper surface of the clamping plate 406 are respectively provided with circular through grooves, so that the needle tube of the needle is located in the circular through grooves, which makes it convenient for the clamping plate 406 to clamp the needle.

[0027] The detection mechanism 2 includes an airbag 201, a positioning block 202, a miniature air pump 203, an image sensor 204, an internal power supply 205, and a microcontroller 206. The positioning blocks 202 are equidistantly arranged and fixedly connected to the tube cap 3, and the airbag 201 is fixedly connected to the positioning block 202. The inner side of the airbag 201 is in contact with the outer wall of the tube body 1. The positioning block 202 has a groove, and the miniature air pump 203, the internal power supply 205, and the microcontroller 206 are respectively installed in the groove.

[0028] The leak-proof mechanism 6 includes a storage rack 601 and an electric telescopic rod 602. The storage rack 601 is located on the inner wall of the pipe body 1 and is fixedly connected. The top of the storage rack 601 is in contact with the sealing block 5. The electric telescopic rods 602 are fixedly connected to the inner wall of the top of the storage rack 601 at equal intervals.

[0031] The disposable human arterial blood sample collection container, as described above, is used by medical personnel who insert one end of a blood-drawing needle into an artery in the arm and the other end of the needle between two clamping plates 406. A spring 404 pushes the clamping plates 406, clamping the needle and pushing a limiting plate 405, causing one end of the limiting plate 405 to enter the other clamping plate 406. The limiting plate 405 restricts the flat portion of the needle, increasing the area for insertion. The medical personnel press an arc-shaped plate 402, which moves the needle between the two clamping plates 406, facilitating insertion into the sealing block 5. After blood collection, a micro-pump 203 inflates the airbag 201, causing it to expand. The system will completely cover tube 1. The image sensor 204 identifies the information of the person taking tube 1. After identification, the microcontroller 206 shuts down the air pressure sensor, allowing medical personnel to take the tube. If the identity of the person taking the tube cannot be identified, the airbag 201 outside tube 1 is pressed when taking the tube. When the airbag 201 is pressed, the air pressure sensor detects the gas inside the airbag 201. When the air pressure inside the airbag 201 changes, the air pressure sensor transmits the information to the microcontroller 206, which then activates the electric telescopic rod 602 to extend and retract. The needle on the electric telescopic rod 602 punctures the plastic film of the storage rack 601, allowing the liquid inside the storage rack 601 to enter tube 1, thus destroying the blood sample inside tube 1 and preventing leakage.
