The components of the implementations of the present application, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Example 1

Referring to fig. 1, a saliva sample collecting bag comprises a first bag body 1 and a second bag body 2, wherein the second bag body 2 is integrally connected to the bottom of the first bag body 1, a sealable sample inlet 11 is arranged on the first bag body 1, and a sealable sample inlet 21 is arranged on the second bag body 2; when the sampling port 21 is opened, the first bag body 1 and the second bag body 2 are communicated. It should be noted that, the sealing manner of the sample inlet 11 and the sampling port 21 may be sealed by using a sealing clip or heat sealing, and in this embodiment, in consideration of sealing performance and easiness in changing the sealing state, the sealing strips 5 are disposed on the sampling port 21 and the sampling port 11 to achieve the sealing effect, and the sealing strips 5 are commercially available self-sealing strips.

In this embodiment, the usage of the collecting bag is as follows:

step 1: inserting the second pouch body 2 into the liquid storage tube 4;

and 2, step: the sampler 3 chewed by the pigs is put into the first bag body 1 through the sample inlet 11;

and step 3: the sample inlet 11 is closed, and the sampler 3 is squeezed and pinched with force, so that the saliva in the sampler 3 flows out, and flows into the second bag body 2 through the sample outlet 12 and the sample port 22.

And 4, step 4: the sample outlet 12 is closed, and the residual sample in the diversion bag 6 is cleaned.

And 5: the sampling port 21 is closed, the flow guide bag 6 is cut off, the cap of the liquid storage tube 4 is closed, and the sample is sent.

In a normal state, the sample outlet 12 and the sampling port 21 are opened.

Through the structure, the sealed sampling and the sealed sample feeding can be realized, the contact between the sample and the external environment when the liquid storage pipe 4 is installed and disassembled is prevented, and the sample is kept pollution-free.

In this embodiment, after the second bag body 2 is sampled and cut off from the first bag body 1, a gap is left at the bottom of the first bag body 1, and if there is a residual sample in the first bag body 1, the residual sample can flow into the external environment, which causes environmental pollution, therefore, preferably, a sealable sample outlet 12 is further provided at the upper part of the second bag body 2, and the sample outlet 12 is located between the sampling port 21 and the bottom of the first bag body 1; after the second bag body 2 is about to take a sample, the sample outlet 12 at the bottom of the first bag body 1 is sealed, a sample remained between the sample outlet 12 and the sample outlet 21 is squeezed into the second bag body 2, then the sample outlet 21 of the second bag body 2 is sealed and the diversion bag 6 is cut off, so that the residual sample in the first bag body 1 can not flow into the environment after the second bag body 2 is cut off, and the environmental pollution is caused.

In this embodiment, in order to facilitate the operator to take a plurality of samples at a time, preferably, the bottom of the first bag body 1 is provided with a plurality of second bag bodies 2 which are uniformly distributed, and the sealing strips 5 of the sample outlet 12 of the first bag body 1 and the sampling port 21 of the second bag body 2 are used for sequentially sampling the plurality of second bag bodies 2 arranged at the bottom of the first bag body 1, so that the loss of the samples and the contact with the external environment caused by the replacement of the liquid storage tube 4 during multiple sampling are avoided, and the probability of the samples being polluted by the external environment is reduced.

In this embodiment, conventionally, in order to make the sample in the first bag body 1 more easily flow to the second bag body 2, the sample outlet 12 is connected with the diversion bag 6 having a wide upper part and a narrow lower part, the upper and lower sides of the diversion bag 6 are both open, and the second bag body 2 is connected with the lower part of the diversion bag 6.

In this embodiment, in order to observe the flow of saliva in the first bag body 1 and the second bag body 2, the first bag body 1 and the second bag body 2 are made of transparent plastic materials.

Example 2

Referring to fig. 2-3, a saliva sample collecting device comprises a saliva sample collecting bag and a liquid storage tube 4, wherein the second bag 2 is placed inside the liquid storage tube 4, in this embodiment, a sample collected by a sampler 3 is squeezed into the first bag 1, then the sample outlet 12 and the sample outlet 21 are kept in an open state, the sample sequentially flows through the sample outlet 12, the sample outlet 21 and enters the second bag 2 to collect the sample, the sample outlet 12 is sealed, the sample between the sample outlet 12 and the sample outlet 21 is squeezed into the second bag 2 to complete the collection, the sample outlet 21 is sealed, the second bag 2 is cut off between the sample outlet 12 and the sample outlet 21, the second bag 2 is placed in the liquid storage tube 4 to complete the whole sampling operation, and if a plurality of samples need to be collected, the steps are repeated. This design makes and does not take place the contact between saliva in the sampling process and the external environment, has not only protected the sample the purity, also make the external environment not contaminated to make sample operation convenient and efficient through appearance mouth 12, sample connection 21 and place the second bag body 2 in the liquid storage pipe 4 in and, also can take a plurality of samples simultaneously, improved the efficiency of sampling.

In this embodiment, in order to prevent the liquid storage tube 4 from being unable to accommodate the second pouch body 2 due to its small volume, it is preferable that the diameter of the liquid storage tube 4 is larger than the diameter of the sampling port 21, and the length of the liquid storage tube 4 is larger than the length of the second pouch body 2.

In this embodiment, it is preferable that the device further comprises a sampler 3, and the sampler 3 is a water-absorbing strip-shaped object or a rope. It should be noted that the sampler 3 may be made of cotton, sponge, rayon, or other materials, and may be made into a strip or rope shape, and in this embodiment, a cotton rope is selected as the sampler 3 in consideration of water absorption and wear resistance, one end of the cotton rope is fixed, the other end faces the oral cavity of the pig, the pig chews the cotton rope, and at this time, the cotton rope absorbs saliva, and the sample is collected. Then a cotton string is put inside the first pouch body 1 and saliva is squeezed out.

To sum up, a saliva sample collection bag and collection device, this design is through the integration of first bag body and second bag body and be located the play appearance mouth of first bag body bottom and be located the sample connection of second bag body top for do not take place the contact between saliva in the sampling process and the external environment, not only protected the purity of sample, also make the external environment not contaminated, and through going out the appearance mouth, the second bag body that sample connection and interior place in the liquid storage pipe makes the security that send the appearance process improve, a plurality of samples also can be taken simultaneously to a plurality of second bag bodies that first bag body bottom set up simultaneously, the efficiency of sampling has been improved.
