Problems solved by technology

[0005] However, when adopting the scheme in the above-mentioned utility model, medical personnel still need to manually adjust the switches on different pipelines, so as to control whether the blood in different pipelines circulates, and the automatic adjustment of each pipeline cannot be realized, and the operation is relatively complicated.
Especially when there are many pipelines, multiple pipelines are staggered together, so it is easy for the medical staff to distinguish which pipeline is connected with the corresponding blood collection test tube, and it is easy to cause the blood in the pipeline to flow when the medical personnel control the switch. Phenomenon that enters the blood collection tube that has already collected blood

Embodiment 1

[0026] Basic as attached Figure 1-Figure 2Shown: a blood collection device, including a base 1 and a riser 5, the base 1 is located at the bottom of the riser 5, and is fixedly connected together by screws. The base 1 is provided with three placing grooves for placing the blood collection test tubes 2, the vertical plate 5 is provided with a cylinder groove, and a cylinder (not shown) is installed in the cylinder groove, and a motor 12 is installed on the cylinder rod of the cylinder by screws. Therefore, the motor 12 can be moved closer to and away from the riser 5 through the expansion and contraction of the cylinder rod. The motor 12 is connected with a reducer 13, and the reducer 13 is also installed on the cylinder rod through screws. The reducer 13 in this embodiment is a gear structure reducer. Speed ​​reducer 13 is connected with the turning roller 17 that is positioned at its left side, and when motor was close to riser 5, the sidewall of turning roller 17 can stick...

Embodiment 2

[0032] combine Figure 2-Figure 4 The difference between embodiment 2 and embodiment 1 is that: a cavity is provided in the rotating roller 17, and a rotating rod 16 is connected to rotate in the cavity. Specifically, a rotating hole is provided at the middle position of both ends of the rotating roller 17, and the rotating rod 16 passes through the turning hole, and three extruding wheels 27 are welded on the turning bar 16, and three sliding blocks are all arranged on each slotted hole 19, and three sliding blocks are successively the first sliding block 23, the second sliding block 24 and the third sliding block 25, the first sliding block 23 is slidingly connected with the left side inner wall of the slot hole 19, and the third sliding block 25 is slidingly connected with the right side inner wall of the slot hole 19, and the second sliding block 24 can be respectively It is slidably connected with the first sliding block 23 and the third sliding block 25 , and the specifi...

Abstract

The invention relates to the field of medical equipment, in particular to a blood collection device, which includes a base and a vertical plate, which are fixedly connected, the base is provided with a plurality of placement slots for placing blood collection test tubes, and the vertical plate is equipped with a motor. A speed reducer is connected to the speed reducer, and a rotating roller is connected to the speed reducer. There are several slots arranged on the rotating roller, and the several slots are arranged along the axial direction of the rotating roller. The projections of the several slots on the axial direction of the rotating roller are evenly distributed; There are multiple sets of limit buckles on the board. This scheme realizes the automatic control of different pipelines.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a blood collection device. Background technique [0002] At present, when diagnosing diseases, it is necessary to collect blood from the patient. When collecting blood, the medical staff will pierce the needle of the blood collection needle into the blood vessel of the patient, and then remove the protective cover on the plug end of the blood collection needle connected by a flexible tube. The staff inserts the plug end into the blood collection test tube, and relies on the negative pressure in the blood collection test tube to realize blood collection. [0003] However, due to the need to check multiple health indicators of the patient, it is often necessary to take multiple blood samples at the same time, so multiple blood collection test tubes are needed. Pull out the end, insert the end of the puncture plug into another blood collection test tube, and so on, complete the blo...
