Suction cup type film-taking apparatus

Abstract

The invention discloses a sucker-type film taking device, which comprises an outer casing and a negative-pressure lifting sheet cover fixed at the bottom of the outer casing, wherein a pressure relief hole is arranged in the middle of the outer casing, and a pressure relief valve and a pressure relief valve are arranged inside the outer casing. The inner casing, the bottom of the inner casing is provided with a spring platform, the two sides of the spring platform are provided with a return spring, the upper part of the return spring is provided with the pressure relief valve, the upper part of the pressure relief valve is airtight, and the upper part of the pressure relief valve is provided with The pressure relief ball, the upper part of the pressure relief ball is provided with a soft membrane, and the two sides of the upper part of the pressure relief valve are provided with through holes, the pressure relief valve is connected to the inner casing by sliding, the spring platform is in the shape of a ring, and the spring platform is connected to the inner casing. The casings are fixedly connected, and the inner casing and the outer casing are fixedly connected. The pressure relief ball is fixedly connected with the pressure relief valve, and there is a channel inside the pressure relief valve, which communicates with the negative pressure lifting plate cover, and the through hole communicates with the pressure relief hole when the return spring is compressed. The invention has the advantages of simple structure, convenient use and quick taking and unloading of slices.

Description

Technical field: [0001] The invention relates to medical equipment, in particular to a sucker type sheet taking device. Background technique: [0002] X-ray filming machine, computerized radiography system (CR), direct digital radiography system (DR), computerized tomography (CT), nuclear magnetic resonance (MRI), digital subtraction angiography system (DSA), etc. Most of the film processing is done manually. After a film is processed, a new film needs to be reloaded and unloaded. As a result, the hands of the medical staff who process the film are often wet and covered with wet medicine, which can easily lead to new The film will cause pollution, and serious cases will cause diagnostic errors. In order to solve this problem, some sucker type sheet taking devices have appeared on the market. It uses a crossbeam to connect the piston and the air cylinder, the end of the piston is connected to the suction cup, and the suction cup generates suction by pulling the handle to ...
