The invention belongs to the technical field of medical devices, and in particular relates to a disposable intravenous infusion needle gas detection instrument. The gas detection instrument includes amain body, a first joint part and a second joint part. The first joint part is provided with an external wall groove. The external wall groove is provided with a first clamping bag therein. The mainbody is provided with a gas inlet pipe and a gas outlet pipe. The gas inlet pipe separates the cavity of the main body into a left cavity and a right cavity. The left cavity is provided with a first sliding block therein. The right cavity is provided with a second sliding block therein. The left cavity is provided with a first stopper. The right cavity is provided with a second stopper. The main body and the first joint part are provided with a first channel and a second channel. The main body is provided with a third channel thereon. A needle cannula jacket is sleeved with a second clamping bag. According to the invention, the technical solution overcomes technical defects in using disposable intravenous infusion needle gas detection instruments in the prior art, such as the need for a man to clamp a needle end and uneasy operation. The technical solution provides a disposable intravenous infusion needle gas detection instrument which is easy to operate and great in applicability.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, and specifically discloses an air detector for disposable intravenous infusion needles. Background technique [0002] Disposable intravenous infusion needle is a commonly used hospital infusion device, the structure is as follows figure 1 As shown, it includes a needle 1 and an intravenous infusion needle channel 2 , and the head of the intravenous infusion needle channel 2 is connected to the needle 1 . [0003] Disposable intravenous infusion has certain requirements for its tightness and whether the channel and needle are unimpeded. At present, when producing disposable intravenous infusion needles, the general method for its detection is to adopt manual operation. Moreover, when checking its airtightness and checking whether the intravenous infusion needle channel and the needle are unimpeded, the detection test is carried out separately. As a result, the entire detection process...
