Disposable spray head module suitable for biomedical detection

Abstract

The invention discloses a disposable spray head module suitable for biomedical detection. The disposable spray head module comprises a base and a containing bottle, wherein a spray head assembly is arranged inside the base; a puncture part, a fastening part and an isolating assembly are arranged on the spray head assembly; the containing bottle is used for containing liquid and provided with an opening, and the opening is sealed by a diaphragm; when the containing bottle is arranged on the base, the diaphragm of the containing bottle is arranged corresponding to the puncture part of the base; and the opening of the containing bottle is blocked on the fastening part of the base, so that the puncture part penetrates through the diaphragm for guiding the liquid in the containing bottle to flow to the spray head assembly by virtue of the puncture part, and guiding clean gas to adjust the internal pressure of the containing bottle by virtue of the isolating assembly, and therefore, micro-droplets are sprayed out by the spray head assembly.

Description

technical field [0001] The invention relates to a disposable nozzle module, especially one that is suitable for biomedical detection, and can prevent the detection liquid from being polluted by the outside, and then achieve non-toxic, sterile, labor-saving, time-saving and can be discarded as a whole after use. Disposable sprinkler module. Background technique [0002] With the increasing emphasis on medical quality, the efficiency and accuracy of biomedical testing has also become a link that cannot be ignored. Fast and accurate test reports can assist in the early detection of many diseases for subsequent treatment. In the current biomedical detection system, the inspectors first extract the detection reagents into the syringe, and then drop the detection reagents into the test tubes to perform screening tests and analyze the results. However, this biomedical detection method is not only time-consuming and expensive. It is labor-intensive, and the droplet volume of the de...

Problems solved by technology

[0005] An object of the present invention is to provide a disposable nozzle module suitable for biomedical detection, which uses the fastening part on the base to lock and fix the opening of the container bottle, and uses the puncture part on the base The diaphragm passing through the opening of the holding bottle, so that the liquid in the holding bottle can flow to the spray head assembly through the guidance of the piercing part, and guide the clean gas through the isolation assembly on the base to adjust the internal pressure of the holding bottle , so that the micro-droplets are sprayed from the nozzle assembly to solve the time-consuming inspection of the known technology, the droplet volume of the drug solution cannot be accurately controlled, and the analysis results are easily distorted due to human error, and it can avoid the liquid in the drug bottle. The pharmaceutical solution is polluted by the outside world, so as to achieve the purpose of non-toxic, sterile, labor-saving, time-saving and the whole group can be discarded after use
