Problems solved by technology

Although this can avoid the waste of the cytoprotective agent, manual operation cannot ensure that the cytoprotective agent is evenly injected into the blood bag, which has the risk of destroying the cell activity in the blood sample, and also increases the labor intensity of the medical staff. In the end, Potentially a result that outweighs the gain

Embodiment Construction

[0046] The method for injecting the liquid in the syringe with the micropump provided in this embodiment is preferably carried out in a clean bench, and the micropump is erected using the micropump support device described in detail below. First use the syringe to suck the cell protection agent into the syringe, and after using the syringe to suck the liquid into the syringe, continue to suck the air into the syringe; then install the syringe of the suction cell protection agent on the micropump, and the injection The hole faces downward, and the injection hole is connected to the inlet of the pipeline for delivering the cell protection agent, and the outlet of the pipeline is communicated with the blood bag containing the blood sample. The parameters of the micropump are set according to needs, and the setting of the parameters is a prior art. Finally start the micropump.

[0047] In this embodiment, after the liquid is sucked into the syringe with the syringe, the air is co...

Abstract

The invention discloses a method for ejecting liquid in an injector by a micro pump and a micro pump support device. The method comprises the following steps of: firstly, sucking the liquid into the injector, then installing the injector with the sucked liquid onto the micro pump, connecting a pipeline for delivering the liquid, setting parameters of the micro pump according to demands, and finally, starting the micro pump; after the liquid is sucked into the injector independently, sucking air into the injector; and erecting the micro pump through a support, wherein an injection hole of the injector is downward. The micro pump support device comprises a base and the support connected with the base, wherein the support is provided with a cross bar above the base, and a plurality of fixing devices for fixing the micro pump are distributed on the cross bar. The method and the device can avoid intermittence and waste of liquid, and also reduce the labor intensity of medical workers.

Description

technical field [0001] The invention relates to a method for ejecting liquid in a syringe and a support device, in particular to a method for ejecting liquid in a syringe with a micropump and a support device for the micropump. The method and the device are for non-diagnostic and non-therapeutic purposes. Background technique [0002] The micropump is a tool specially used to control the syringe to deliver liquid at a constant speed and quantitatively. Medical micropumps have the advantages of accurate dosage, no volume load and easy operation. In the prior art, in order to maintain the activity of cells in the blood sample, it is necessary to add a cytoprotective agent to the blood sample. The flow of cell protectant added should always be the same. Therefore, it is a good choice to control the syringe to deliver liquid at a constant speed and quantitatively through a micropump. The usual method is: first use a syringe to inhale the cell protectant into the syringe, in ...
