[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Combined with the embodiments and appendix Figure 1-4 A sheep ear vein micro-blood collector includes a detachably connected sampling tube 1 and a blade head, the blade head includes a handle 21 connected to a blade 22, and the handle 21 is connected to a fixing ring 23 that is detachably connected to the sampling tube 1; one end of the sampling tube 1 is closed, and the other end is adjustably connected to a tube cap 13, and a capillary tube 12 is inserted into the tube cap 13; a negative pressure blood sampling cavity 10 is separated by a sealing membrane 11 in the sampling tube 1, and the capillary tube 12 is located above the sealing membrane 11; the sampling tube 1 and the tube cap 13 are both made of flexible plastic.

[0017] The middle part of the handle 21 is connected to the fixing ring 23 through the connecting handle 25. The inner wall of the fixing ring 23 is covered with a non-slip washer, the inner diameter of which matches the outer diameter of the sampling tube. The non-slip washer can be made of rubber or silicone.

[0018] Furthermore, the side wall of the knife handle is radially raised to form an anti-slip handle 24, which is arranged back to back with the connecting handle 25 to facilitate hand-held operation and prevent the knife handle from slipping and flying off during sampling operation.

[0019] The outer wall of the sampling tube 1 is engraved with an external threaded section 14, and the downward distance of the tube cap 13 along the axial direction of the sampling tube 1 is greater than the initial vertical distance between the lower end of the capillary tube 12 and the sealing membrane 11. Rotating the tube cap 13 drives the capillary tube 12 downward into the negative pressure blood sampling chamber 10. During assembly, the lower end of the capillary tube hovers above the sealing membrane, and an adjustable connection achieves adjustable communication between the capillary tube and the negative pressure blood sampling chamber, preventing the capillary tube from accidentally sucking in hair or other debris when operating the cutting head.

[0020] A sheep ear vein micro-blood collector has another adjustable connection method for the tube cap. A protrusion is connected to the outer wall of the sampling tube, and a sliding groove is opened at the position opposite to the protrusion of the tube cap. The protrusion and the sliding groove slide and match, so that the sampling tube can slide relative to the tube cap, driving the capillary tube into the negative pressure blood collection chamber. The operation of the capillary tube entering the negative pressure blood collection chamber can be achieved by sliding the tube cap or sliding the sampling tube.

[0021] Furthermore, the slide is arranged along the axial direction of the sampling tube, and one end of the slide is connected to a changing groove arranged along the circumference of the sampling tube, and the changing groove is connected to the lower wall of the tube cap. The tube cap is moved axially downward to the section where the slide and the changing groove are connected, and the tube cap can be rotated to separate and recycle the tube cap from the sampling tube.

[0022] The lower end of the capillary 12 is a pointed tip, and the inner wall of the capillary 12 is coated with an anticoagulant to prevent the capillary 12 from being blocked. The bottom of the negative pressure blood collection chamber 10 is coated with a coagulant. When the tube cap descends to the lowest point, the lower end of the capillary is located at the upper part of the negative pressure blood collection chamber. Squeezing can conveniently discharge serum for antibody test strip detection.

[0023] There are two fixing rings 23 , and both fixing rings 23 are arranged parallel to the cross section of the sampling tube 1 .

[0024] The blade 22 is a tapered blade, and the tapered blade is arranged on the same side as the capillary.

[0025] When sampling, the epidermal hair is quickly processed by the blade. The conical blade can be used to pierce or scratch, and can be used to form an open wound for easy sampling. After aligning the capillary tube with the wound, the tube cap can be rotated with one hand to drive the capillary tube through the sealing membrane to connect to the negative pressure blood collection chamber, completing the rapid sampling operation; when adding the sample, the sampling tube can be taken out from the fixed ring, and the sampling tube itself is flexible, and the lower end of the sampling tube is squeezed to complete the sample removal operation, and the sample is added to the antibody test strip.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
