Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] refer to figure 1 , is a dried blood spot punching instrument disclosed in the present invention, comprising an outer cover 34 with a horizontal workbench 1 on the outer cover 34 .

[0046] Such as figure 2 As shown, there is a driving assembly 2 and a punching assembly 3 inside the outer cover 34, wherein the driving assembly 2 is a four-axis servo system, and the four-axis servo system is composed of two horizontally arranged and perpendicular guide rails 8, and the upper guide rail 8 is fixed on the lower On the mobile seat 16 of the guide rail 8. The movable seat 16 in the four-axis servo system is detachably connected to the test tube tray 4, and several vertical test tubes are inserted on the test tube tray 4.

[0047] Such as image 3 As shown, the test tube tray 4 is provided with some circular holes 17 for inserting test tubes, and the mo...

Abstract

The invention relates to the technical field of punchers, in particular to a dried blood spot puncher and a punching method thereof. The dried blood spot puncher comprises a workbench, wherein a driving assembly and a punching assembly are arranged on the workbench; a test tube tray is in driving connection to the driving assembly; the punching assembly comprises a punching punch, a punching upperdie and a punching lower knife which are sequentially distributed from top to bottom; a gap is reserved between the punching upper die and the punching lower knife and is used for placing a blood spot acquisition card; a first punched hole is formed in the punching upper die; a second punched hole is formed in the punching lower knife; a punching needle is fixed on the punching punch and is in sliding fit with the inner wall of the first punched hole; the bottom end of the punching needle is in shearing fit with the second punched hole; and an air hole is formed in the central axis of the punching needle. After the dried blood spot puncher is used for punching, blood sheets can be blown into test tubes, and the blood sheets falling into the test tubes cannot fly out of the test tubes dueto the influence of air flow; and the dried blood spot puncher has the advantage of being quiet during working, is efficient and energy-saving, and is suitable for being used in medical places.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a dried blood spot punching instrument and a punching method thereof. Background technique [0002] At present, the operation of blood sheet collection is generally carried out manually, that is, placing a single test tube or collection part under the punching device, and punching the filter paper infiltrated with blood spots to form a blood sheet. The blood sheet outlet falls into the test tube or the collection part, and then the collection part is replaced manually. However, this process requires laboratory personnel to manually operate, which greatly affects the efficiency of work. [0003] In addition, in the above structure, when the blood sheet falls into the test tube and the collection part, due to the influence of static electricity inside the punching device, the blood sheet often deviates during the falling process, that is, the blood sheet may fall into th...
