A kind of instrument for taking liquid of fixed liquid of specimen

Abstract

The invention discloses a specimen stationary liquid taking instrument. The specimen stationary liquid taking instrument comprises a sealed cabinet body, a liquid storage barrel, a liquid pumping device and a microprocessor, wherein the liquid storage barrel is arranged in the cabinet body; the liquid pumping device is connected to the liquid storage barrel and used for pumping liquid; and the microprocessor is electrically connected with the liquid pumping device. One side of the cabinet body is provided with a cabinet door device capable of being opened and closed. A liquid outlet pipe is connected to the outlet end of the liquid pumping device. The cabinet body is provided with a detection sensor for detecting the open state and the close state of a cabinet door. The detection sensor is electrically connected with the microprocessor and controls starting or stopping of an air circulating filtration device. According to the specimen stationary liquid taking instrument, specimen liquid can be prevented from volatilizing into the ambient environment during liquid taking, and formaldehyde in the cabinet body is purified; and the instrument is safe, reliable and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an instrument for taking liquid from a specimen fixative. Background technique [0002] In hospital operating rooms, pathology departments, social health centers, laboratories, etc., specimen solutions are usually used to preserve, disinfect, and soak tissue samples for inspection. Formaldehyde solution is the most common specimen solution, which has the following hazards: 1. Direct contact with human skin may cause allergies, skin inflammation or eczema, especially for people who need to be exposed to formaldehyde for a long time at work, such phenomena often occur; 2. Formaldehyde is highly volatile, highly irritating and harmful to the eyes; 3. When inhaled by the human body, it will irritate the mucous membranes of the mouth, nose and respiratory tract, ranging from painful coughing to severe respiratory inflammation and even pulmonary edema; 4. Many scientific stu...

Problems solved by technology

Although the specimen collection truck with this structure adopts a closed cabinet, which can simply isolate formaldehyde from volatilizing into the environment, formaldehyde cannot be removed in the cabinet. When there is a lot of formaldehyde in the cabinet, the formaldehyde will still It will volatilize outward from various gaps and pollute the environment. When the cabinet is opened, formaldehyde will diffuse and escape, affecting human health
