Description

A kind of clinical medical flora detection device

technical field

The utility model belongs to the field of flora detection, in particular to a flora detection device for clinical medicine.

Background technique

As we all know, it is often necessary to detect the intestinal flora in clinical medicine. During the detection, it is necessary to collect a stool sample, and then place the stool sample into a corresponding flora detection reagent tube.

However, the existing clinical flora detection devices, such as intestinal flora detection reagent tubes, often use the collection spoon worn by the flora detection reagent tube when collecting stool samples, and the required stool samples are collected by the collection spoon. Collected into the flora detection reagent tube, because the stool has a certain viscosity, this will cause the stool to easily adhere to the collection spoon and cannot fall off, which will affect the subsequent stool collection work. When the stool sample is stored in the detection reagent tube, the collection spoon is likely to be in contact with the nozzle of the flora detection reagent tube, so that the stool sample is likely to adhere to the nozzle of the flora detection reagent tube, so it is very dirty.

Therefore, it is very necessary to invent a clinical flora detection device.

Utility model content

In order to solve the above technical problems, the utility model provides a technical solution adopted by a clinical flora detection device: a clinical flora detection device, including a flora detection tube, an external thread connection port, a large sealing cover, Piston rod and anti-slip groove, wherein: the top of the flora detection tube is fixedly installed with an external threaded connection port, and the external threaded connection port is threadedly connected with a large sealing cover, and the outer surface of the large sealing cover is uniformly provided with anti-slip grooves; One end of the piston rod slides through the large sealing cover and penetrates into the inside of the flora detection tube; the inner side of the large sealing cover is fixed with a C-shaped tube; the piston rod is in the C-shaped tube and slides with the C-shaped tube connection; the C-type tube is inside the flora detection tube; the C-type tube is used to prevent the sample from contacting the detection nozzle.

When the utility model detects the intestinal flora, first, the large sealing cover is separated from the flora detection tube, and then the small sealing cover is twisted to separate the small sealing cover from the external thread connecting pipe, and the piston rod can be pulled at this time , so that the piston rod drives the sampling spoon to leak from the C-shaped tube. At this time, the stool can be sampled through the sampling spoon. After the sampling is completed, pull the piston rod again so that the piston rod drives the sampling spoon into the C-shaped tube for hiding , so that when the stool sample is transferred to the flora detection tube, the sampling spoon can be prevented from contacting the external thread connection port at the top of the flora detection tube, thereby preventing the stool from accidentally adhering to the external thread connection port, making it more clean and hygienic; When the sampling spoon has completely entered the flora detection tube, the sampling spoon can be pushed out of the C-shaped tube through the piston rod again, and then the stool sample in the sampling spoon can be poured into the flora detection tube. The stool sample in the sampling spoon accidentally adheres to the sampling spoon and cannot be poured down. At this time, the sampling spoon can be brought into contact with the scraper, so that the scraper enters into the sampling spoon, and then the piston rod is turned to make the scraper hold the stool in the sampling spoon. The stool sample can be scraped out, so that it is convenient to continue the sampling work, making it very convenient. Finally, after the sampling is completed, pour the corresponding detection solution into the flora detection tube.

One side of the inner surface of the flora detection tube 1 is fixedly equipped with a scraper 3; the scraper 3 is used to scrape off the stool sample inside the sampling spoon 8; the size of the scraper 3 is smaller than the size of the cavity of the sampling spoon 8, and the scraper The height of 3 is higher than the height of sampling spoon 8;

The size of the C-type tube 6 is smaller than the size of the bacterial flora detection tube 1 and the external thread connection port 2, and the height of the scraper 3 is higher than the height of the sampling spoon 8, that is to say, between the large sealing cap 4 and the flora detection tube 1 In the case of no connection, the C-shaped tube 6 and the sampling spoon 8 have an active space in the flora detection tube 1. When the sampling spoon 8 leaks from the C-shaped tube 6, due to the active space, the sampling spoon 8 can Close to the scraper 3, the cavity of the sampling spoon 8 can be placed outside the scraper 3, that is to say, the scraper 3 is passively entered into the cavity of the sampling spoon 8; When the stool sample is poured into the flora detection tube 1, the sample in the sampling spoon 8 can be scraped out by the scraper 3, so as to facilitate the continuation of the sampling work.

In this embodiment, when detecting intestinal flora, first, turn the large sealing cover 4 to separate the large sealing cover 4 from the flora detection tube 1, and then twist the small sealing cover 9 to make the small sealing cover 9 and the outer The threaded connecting pipe 5 is separated, and now the piston rod 7 can be pulled, so that the piston rod 7 drives the sampling spoon 8 to leak out from the C-shaped pipe 6, and now the stool can be sampled by the sampling spoon 8. After the sampling is completed, again Pull the piston rod 7 to make the piston rod 7 drive the sampling spoon 8 into the C-shaped tube 6 to hide, so that when the stool sample is transferred to the flora detection tube 1, the sampling spoon 8 can be prevented from colliding with the top of the flora detection tube 1 The external threaded connection port 2 of the external thread contact, so as to avoid the accidental adhesion of stool on the external threaded connection port 2, making it more clean and hygienic; when the sampling spoon 8 completely enters the flora detection tube 1, it can pass through the piston rod again 7 Push the sampling spoon 8 out of the C-shaped tube 6, and then pour the stool sample in the sampling spoon 8 into the flora detection tube 1. When the stool sample in the sampling spoon 8 accidentally adheres to the sampling spoon 8, it cannot Fall down, at this time, the sampling spoon 8 can be brought into contact with the scraper 3, and the scraper 3 can enter the sampling spoon 8, and then the sampling spoon 8 can be rotated by the piston rod 7, so that the scraper 3 can touch the stool sample in the sampling spoon 8. Just scrape it out, so that it is convenient to continue the sampling work, making it very convenient. Finally, after the sampling is finished, pour the corresponding detection solution into the flora detection tube 1 and get final product.
