Description

Technical Field

[0001] The utility model relates to the technical field of blood sampling, in particular to a blood testing sampling device. Background Art

[0002] Blood testing is a project to test the blood components of the human body. It can detect parameters such as liver function, blood sugar, blood lipids, blood pressure, blood sugar, etc. for medical staff to refer to and judge, so as to detect diseases in time. Blood testing requires drawing blood from patients. Most existing blood drawing devices take out the blood sample tube from the test tube rack, and then use the blood drawing tube to draw blood under negative pressure. After the blood drawing is completed, the blood sample tube is placed in the test tube rack and then sent for unified monitoring. However, most existing blood tubes are placed in the test tube rack with a snap connection. A more stable snap connection will make it difficult to take the test tube when drawing blood, and a looser snap connection will cause the blood tube to shake when moving, which can easily cause the blood tube to fall.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a blood test sampling device, comprising a sampling tube 1 and a fixed card seat 2 placed in a test tube rack, a placement groove 7 is opened in the fixed card seat 2, the placement groove 7 corresponds to the sampling tube 1, a rubber ring 4 is sleeved on the sampling tube 1, a card block 6 is fixed in the placement groove 7, the card block 6 corresponds to the rubber ring 4, a blood sampling tube 8 is installed on the sampling tube 1, a needle 9 and a fixed block 10 are fixed at one end of the blood sampling tube 8, a sliding block 12 is elastically fitted in the fixed block 10, and the sliding block 12 corresponds to the needle 9.

[0022] In this embodiment, a slot 5 is provided in the rubber ring 4 , and the slot 5 corresponds to the block 6 . A limit block 3 is fixed on the sampling tube 1 , and the limit block 3 is located on the upper side of the rubber ring 4 .

[0023] Specifically, before blood collection, the sampling tube 1 is directly placed in the test tube rack. At this time, the bottom of the sampling tube 1 is located in the placement groove 7. After blood collection is completed, the rubber ring 4 is put on the sampling tube 1, and then the sampling tube 1 is inserted into the test tube rack so that the rubber ring 4 enters the placement groove 7. The card slot 5 and the card block 6 form a card connection relationship, and the sampling tube 1 can be carded and fixed to prevent the sampling tube 1 from shaking.

[0024] A slide groove 11 is provided in the fixed block 10, and the slide groove 11 corresponds to the sliding block 12. A plurality of springs 13 are fixed between the sliding block 12 and the groove wall of the slide groove 11. The sliding block 12 is fixedly connected to the needle 9. A protective cover 14 is provided on the lower side of the sliding block 12, and the protective cover 14 corresponds to the needle 9. A flow regulator 15 is provided on the blood collection tube 8. A positioning groove 16 is provided in the fixed block 10, and the positioning groove 16 corresponds to the sliding block 12.

[0025] Specifically, when drawing blood, the protective cover 14 is pulled out, and the fixed block 10 can be used to position the needle 9 first to ensure that the needle 9 can be inserted into the blood vessel. Then, the sliding block 12 is pushed so that the sliding block 12 drives the needle 9 to move, and the needle 9 can be inserted into the blood vessel. Then, the sliding block 12 is pushed to one side so that the sliding block 12 enters the positioning groove 16. The sliding block 12 and the positioning groove 16 are engaged with each other, and the needle 9 can be fixed. When the blood drawing is completed, the sliding block 12 is toggled, and the sliding block 12 loses the engaging relationship with the positioning groove 16. The spring 13 rebounds and the needle 9 can be quickly pulled out.
