Puncture device with multi-needle structure for blood detection

Abstract

The invention discloses a puncture device with a multi-needle structure for blood detection. The puncture device comprises an upper shell and sampling cups, wherein a bottom end of the upper shell isin threaded connection with a top end of a lower shell, top ends of connecting frames are connected to bottom ends of driving boards that are vertically distributed, outer tubes horizontally distributed are arranged inside the upper shell, and two ends of each outer tube are rotationally connected to breaks of sleeves. A bracket is connected between the sleeves at two ends. Tail ends of the sleeves pass through the upper shell to extend to upper parts of the sampling cups, the sampling cups are mounted on an outer surface of the lower shell through buckles, and the buckles are fixedly connected to the lower shell. The puncture device with the multi-needle structure for blood detection is provided with a corresponding needle tube slide structure based on the multi-needle structure, so thata selected needle tube at a specified position can conveniently slide out to puncture by movement of a pressing plate, and blood can be conveniently sampled by sliding movement of the needle tube, sothat the design is more reasonable.

Description

technical field [0001] The invention relates to the technical field of medical testing equipment, in particular to a puncture device for blood testing provided with a multi-needle structure. Background technique [0002] In hospitals, blood testing is a relatively common detection method. After the designated skin site is sterilized, a puncture device is used to puncture it. The needle tube passes through the cortex to reach the blood vessel, and is exported to the blood vessel through the needle tube and the internal structure of the device. In the sampling cup, in order to improve the detection and sampling efficiency, a multi-needle structure is used in the prior art; [0003] For example, the authorized patent with the publication number of CN207186624U (a puncture needle for medical blood testing) includes a housing in which a piston chamber and a shunt chamber are sequentially opened from top to bottom, and the piston chamber communicates with the shunt chamber.

Problems solved by technology

[0006] The purpose of the present invention is to provide a puncture device for blood testing with a multi-needle structure, to solve the above-mentioned background technology that the needles are scattered in a radial structure distribution, and different needle tubes are used in different positions, but when the puncture operation , the needle tube at the side position is very easy to cause accidental injury to the skin, and there is no reasonable design of the relevant storage structure; the blood in the needle tube at different positions will flow into the unified cavity inside the device during the sampling process, and the blood at different positions will If it is mixed with the residual blood from the previous sampling process, the subsequent test results of the blood will naturally be affected
