Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically, the utility model relates to a sample extraction device for medical detection. Background Art
[0002] Medical examination is a science that examines materials taken from the human body in aspects such as microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc., so as to provide information for the prevention, diagnosis, and treatment of human diseases and the evaluation of human health. Usually, the samples to be detected are made into a liquid state, which is more conducive to the separation, observation, and detection of substances in the samples. However, in many detection method steps, it is necessary to extract the components separated from the samples. However, when conducting a large number of sample detections, the efficiency of single-branch sampling or single-row sampling methods far fails to meet the required standards, and there is also a possibility of cross-contamination between the samples to be detected. Content of the Utility Model

[0007] A nozzle ejector, assembled by an upper pressing plate and a bottom tray. The upper pressing plate includes a cover plate, a plurality of nozzle unloading tubes are evenly and fixedly connected to the bottom of the cover plate, limit columns are fixedly connected to the four corners of the bottom of the cover plate, the bottom of the limit column is slidably sleeved in the first column cylinder, the bottom tray includes a tray, the four corners of the bottom of the tray are fixedly connected with the first column cylinder, the bottom of the first column cylinder is fixedly connected with a column rod, the bottom of the column rod is slidably sleeved in the second column cylinder, and a plurality of nozzle unloading holes are evenly formed on the surface of the tray;
[0008] Base, including a platform, on the upper surface of which four corners are fixedly connected with cylinder tubes II, and a lofting assembly is fixedly connected to the upper surface of the platform.
[0009] As a preferred technical solution of the present utility model, the lofting assembly includes a lofting table. Near one end of the inner side of the lofting table close to the top, an upper clamping groove is opened. Below the upper clamping groove, a lower clamping groove is opened. An isolation plate is movably clamped in the upper clamping groove, and a pipe rack is movably clamped in the lower clamping groove. Sample pipes are evenly placed in the pipe rack.
[0010] As a preferred technical solution of the present utility model, an extension piece is added to the outer side of the isolation plate, which is equivalent to facilitating the extraction of the isolation plate from the upper clamping groove.
[0011] As a preferred technical solution of the present utility model, a liquid suction spring is arranged inside the handle, and the top of the liquid suction spring supports a pressure spring ring, and the pressure spring ring is fixedly connected with a push rod.
[0012] As a preferred technical solution of the present utility model, a nozzle discharging spring is arranged inside the cylinder tube I, and the top of the nozzle discharging spring supports a limiting post.
[0013] As a preferred technical solution of the present utility model, a support spring is arranged inside the cylinder tube II, and the top of the support spring supports a column rod.
[0014] As a preferred technical solution of the present utility model, the suction nozzle passes through the nozzle discharging pipe and a nozzle is detachably sleeved at the lower end.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. By pressing the button above the handle, the present utility model controls the downward movement of the plunger below, discharges the air inside the sleeve group, presses the nozzle into the sample pipe. When the pressure above the button is removed, the liquid suction spring inside the handle pushes the pressure spring ring upward, drives the push rod to move upward, and then drives the plunger to move upward. The pressure inside the sleeve group increases, so that the sample liquid is sucked into the nozzle. By adding multiple rows of suction nozzles, the efficiency of sample extraction can be improved.
[0017] 2. By clamping the isolation plate in the upper clamping groove, when the nozzle extracts the sample liquid from the sample pipe, the isolation plate does not need to be pushed into the upper clamping groove. After the nozzle extracts the sample liquid into the nozzle and withdraws from the sample pipe, at this time, the isolation plate is pushed out of the upper clamping groove, which can prevent the sample liquid in the nozzle above the isolation plate from dripping into the sample pipe below and causing the sample liquid to be contaminated. The addition of the extension piece is for facilitating the extraction of the isolation plate. Description of the Drawings
