Specimen sampling device for hematologic tumor

Abstract

The invention discloses a specimen sampling device for hematologic tumors. The specimen sampling device comprises a device body, and a control device and a suction device which are arranged in the device body, after specimen sampling is completed, a pull ring is pushed leftwards to drive a lead screw to rotate, a sliding plate drives a needle head and a needle tube to move rightwards, the needle head is pulled out, in the needle head pulling-out process, a driving assembly starts to work, and a movable plate slides rightwards to suck gas on the left side of the movable plate through work of the driving assembly, the liquid suction pipe absorbs tumor liquid exuding from the puncture part of the needle into the collection box, so that the situation that healthy human bodies are infected by the tumor liquid due to the fact that the puncture part of the needle is not cleaned in time after personnel complete sampling is prevented, the personnel are protected to a certain degree, and the workload of medical personnel is effectively relieved, and after puncture, the needle enters the attaching pad, so that the needle is prevented from hurting medical staff during transfer, and the medical staff is protected to a certain extent.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a sample sampling device for blood tumors. Background technique [0002] Cancer is a genetic disease, but not hereditary. It refers to the new organisms formed by the abnormal growth of monoclonal abnormal growth due to the change of genes under the action of carcinogenic factors and the loss of normal regulation of its growth. This neoplasm often forms a localized mass, hence the name. According to the biological characteristics of tumors and their harmfulness to the body, tumors can be divided into two categories: benign tumors and malignant tumors. The former grows slowly, has a clear boundary with surrounding tissues, does not metastasize, and is not harmful to human health. The latter grows rapidly and can be transferred to other parts of the body. It also produces harmful substances, destroys normal organ structures, makes the body dysfunctional, and threatens ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, it is impossible to achieve effective observation and control of the insertion depth of the needle, and when the traditional device is in use, it is impossible to effectively clean and sterilize the puncture site of the needle. It is still impossible to effectively absorb the tumor fluid flowing out of the puncture site, and a sample sampling device for blood tumors is proposed
