A device for sampling and submitting tumor effusion

Abstract

The invention relates to the technical field of auxiliary medical equipment, and provides a tumor effusion sampling and inspection device, comprising an effusion tank, a needle tube, a pump, and a connecting tube connecting the above-mentioned effusion box (1), needle tube and pump (2). , and also includes a high-pressure gas source, an anesthetic medicine box and a control assembly, the needle tube includes an inner tube and an outer tube, the outer tube is fully wrapped in the inner tube, the inner tube is used to extract tumor effusion, and the outer tube is used to spray anesthetics; Before the tissue, anesthesia is sprayed into the tissue to be punctured through a high-pressure gas source to make it anesthetized and reduce the pain of the patient.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical equipment, in particular, to a device for sampling and submitting tumor effusion. Background technique [0002] For example, the Chinese patent with the application number: 201810079309.2 discloses a tumor effusion extraction device. By setting a penetration hole on the outside of the needle tube, the anesthetic is infiltrated, so that the outer cannula will benefit from the anesthetic during the puncture, which is effective Alleviate the pain of the patient; however, as we all know, the effective time of anesthesia generally takes 1-2min, and the above-mentioned patent can achieve the penetration of the anesthetic into the tissue after the needle punctures the tissue, so as to realize the anesthesia of the tissue , reduce the pain of the patient; then, the pain of the needle passing through the tissue is still directly felt by the patient, and the above-mentioned patent does not have a ...

Problems solved by technology

[0002] For example, the Chinese patent with the application number: 201810079309.2 discloses a tumor hydrops extraction device, which penetrates the anesthetic by setting a permeable hole outside the needle tube, so that the anesthetic can be released from the outer cannula at the time of piercing, which is effective. Relieve the pain of the patient; however, as we all know, the effective time of the anesthetic generally takes 1-2 minutes, and the above-mentioned patent can realize the penetration of the anesthetic to the tissue after the needle punctures the tissue, so as to realize the anesthesia of the tissue , to reduce the pain of the patient; then, the pain of the needle passing through the tissue is still directly felt by the patient, and the above-mentioned patent does not have a good effect on alleviating the pain, and the pain and pain after the needle punctures the tissue Compared with the pain of tissue puncture, the latter is more painful and more needs to be relieved by anesthesia, so how to complete the puncture of the tissue to be punctured before the needle punctures? Anesthesia treatment is the main technical issue in this case
