Pneumatic cell collector

Abstract

A pneumatic cell collector comprises a main device and an auxiliary device which is attached on the side face of the main device. The main device is used for sucking and storing cells, and air pressure is used as power in the auxiliary device to drive a device in the main device to move to assist in generating negative pressure in the main device for collecting the cells into the main device through a collection port. Negative pressure quantity in a main syringe can be adjusted by opening and closing an auxiliary air outlet in the side face of an auxiliary syringe, so that advantages of single-person operation are retained while limitation of the same is avoided. Realization of perfect and accurate puncturing technology and acquisition of cytology specimens having diagnosis value are facilitated, various dangers are avoided to greatest extent, and clinical application prospect of fine needle aspiration cytology examination is wider. By the pneumatic cell collector, the dangers can be reduced greatly, and success rate and accurate rate of needle biopsy can be increased.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and relates to a clinical collection device for fine-needle aspiration cytology examination, especially a cell collection device. Background technique [0002] Fine-needle aspiration cytology (FNAC) is a cytodiagnostic that uses fine-needle aspiration to absorb cells and other components in the lesion for smears, and observe the morphological changes and interstitial changes of tumor and non-tumor cells. During the implementation process, according to the texture and nature of the tumor, a disposable syringe with a size of about 10 cm can be used for puncture at present. Absorb palpable mass lesions through the patient's body surface, or perform needle aspiration on deep organ lesions guided by X-ray, B-ultrasound, CT and radionuclide scanning, and absorb tiny tissue components (including cells, interstitium or other accompanying substances) ) for cell morphological diagnosis...

AI Technical Summary

Problems solved by technology

The disadvantage is that the operator has to perform both the extensive action of pulling back the needle plug to generate negative pressure, and the fine action of repeatedly sucking the puncture needle into the nodule several times, which is inherently contradictory. Actions require the operator to have strong physical coordination, but most clinicians are obviously difficult to master, which will easily lead to various dangers and reduce the success rate and accuracy of biopsy

Therefore, single-person operation is the most conducive to achieving perfect and accurate puncture techniques and obtaining cytology specimens with diagnostic value, and avoiding various risks to the greatest extent. However, as far as the current equipment is concerned, it is only suitable for physical coordination. Very strong clinicians, because most clinicians are difficult to master the technical essentials, so it is difficult to benefit the public
