Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Embodiment 1

[0050] Patent document CN 211609866 U discloses a cattle and sheep OP fluid collector, which can collect OP fluid from cattle and sheep.

[0051] It can be seen from the clear records in the technical issues of the above-mentioned patent documents that the existing collection tools for cattle and sheep OP fluid are mainly metal probe cups, and the metal probe cup is inserted from the mouth into the pharynx or esophagus (i.e., throat), and the secretions are scraped by pulling the pull rod back and forth. However, the existing probe cup type collector, due to the sharp mouth of the metal probe cup, often causes damage and bleeding to the pharynx, esophagus (i.e., throat) and even the root of the tongue, and is mixed with a large amount of food residue, which will affect the quality of the sample.

[0052] In order to solve the above technical problems, the inventor has adopted a technical solution that is completely different from the patent document CN 211609866 U, which is as follows:

[0053] like Figure 1-8 As shown, the utility model provides a technical solution:

[0054] A cattle and sheep OP fluid collection device includes a syringe 10, which is composed of a syringe 101 and a piston core rod 102 slidably installed in the syringe 101. When the piston core rod 102 is pulled outward, the inner cavity of the syringe 101 can form a negative pressure. A connecting piece 20 is detachably installed on the syringe 101, a flexible tube 30 is detachably installed on the connecting piece 20, and an OP fluid collection component 40 is detachably installed on the flexible tube 30. The OP fluid collection component 40 can be extended into the pharynx or throat of cattle and sheep through the flexible tube 30;

[0055] The OP liquid collection component 40 includes an OP liquid collection head 401, and a collection chamber 403 is provided on one side of the OP liquid collection head 401. The OP liquid collection component 40 can suck the mucus from the pharynx or larynx of cattle and sheep through the collection chamber 403, and the mucus can enter the inner cavity of the syringe 101 through the flexible tube 30 and the connector 20;

[0056] The OP liquid collection component 40 also includes a flexible sampling piece, which is arranged on the OP liquid collection head 401. When the OP liquid collection component 40 is extended into the pharynx or throat of cattle and sheep, the OP liquid collection component 40 can also adhere to mucus through the flexible sampling piece.

[0057] In this embodiment, when sampling and collecting mucus in the pharynx or throat of cattle and sheep (i.e., OP fluid of cattle and sheep), the syringe 10 is connected to the connector 20, the connector 20 is connected to the flexible tube 30, and the flexible tube 30 is connected to the OP fluid collection component 40. Since the syringe 10 is composed of a syringe 101 and a piston core rod 102, in order to collect the OP fluid of cattle and sheep without damaging the pharynx or throat of cattle and sheep, the principle of the syringe 10 can be reversely utilized, that is, the suction principle of the syringe 10 is utilized. In addition, since the collection device uses a combination of the syringe 10, the connector 20, the flexible tube 30 and the OP fluid collection component 40, the collection device also has the practical effect of being portable, which can be convenient for staff to use and carry.

[0058] When collecting OP fluid from cattle and sheep, the flexible tube 30 is inserted into the pharynx or throat of the cattle and sheep.

When the OP fluid collection component 40 contacts the mucus in the pharynx or throat of the cattle and sheep, the staff pulls the piston core rod 102 outward to make the inner cavity of the syringe 101 in a negative pressure state. Under the action of negative pressure, the OP fluid collection component 40 can suck the mucus in the pharynx or throat of the cattle and sheep through the collection chamber 403. After the mucus enters the collection chamber 403, it can continue to enter the flexible tube 30 under the action of negative pressure, and then enter the syringe 101 through the connector 20. After the mucus enters the syringe 101, the collection of OP fluid from cattle and sheep is completed. In addition, during the process of collecting mucus by the OP fluid collection component 40, the pharynx, throat or tongue root of the cattle and sheep will not be damaged, and the collection process is convenient and quick.

[0059] At the same time, the flexible sampling piece provided on the OP liquid collection component 40 can also cooperate with the collection chamber 403. While the OP liquid collection component 40 absorbs mucus through the collection chamber 403, it can also adhere to the mucus through the flexible sampling piece, thereby further improving the sampling effect on the pharynx or throat of cattle and sheep. In addition, the flexible sampling piece will not cause damage to the pharynx, throat or tongue root of cattle and sheep.

[0060] Furthermore, the connector 20 can be easily removed from the syringe 10, one end of the flexible tube 30 can be easily removed from the connector 20, and the other end can be easily removed from the OP liquid collection component 40, thereby facilitating the replacement of the connector 20, the flexible tube 30, and the OP liquid collection component 40.

[0082] Embodiment 6

[0083] like Figure 1-8 As shown, based on the first embodiment, the following improvements are made:

[0084] In order to facilitate the staff to sample and analyze the mucus collected in the syringe 101, in the present embodiment, a breathable water absorbent is further installed in the inner cavity of the syringe 101. The breathable water absorbent can absorb the mucus in the syringe 101 without affecting the coordinated operation of the syringe 101 and the piston core rod 102.

[0085] More specifically, the breathable absorbent member is a water-absorbing cotton sheet 50, which is placed at the bottom of the inner cavity of the syringe 101, wherein the water-absorbing cotton sheet 50 has a plurality of air-permeable gaps, under the effect of the air-permeable gaps, it is possible to facilitate the flow of air, therefore, when the water-absorbing cotton sheet 50 is placed in the inner cavity of the syringe 101, it will not affect the pulling and drawing movement of the piston core rod 102 on the syringe 101;

[0086] Moreover, the absorbent cotton sheet 50 is a better form of breathable absorbent.

The absorbent cotton sheet 50 can be placed in a testing instrument, and the cattle and sheep OP fluid in the absorbent cotton sheet 50 can be tested and analyzed by the testing instrument.

[0087] Embodiment 7

[0088] like Figure 1-8 As shown, based on the first embodiment, the following improvements are made:

[0089] In order to optimize the implementation form of the flexible tube 30 , in this embodiment, further, the flexible tube 30 is a medical catheter.

[0090] In summary, the workflow of the utility model is:

[0091] like Figure 1-8 As shown, when sampling and collecting mucus in the pharynx or throat of cattle and sheep (i.e., OP fluid of cattle and sheep), the syringe 10 is connected to the connector 20, the connector 20 is connected to the flexible tube 30, and the flexible tube 30 is connected to the OP fluid collection component 40. Since the syringe 10 is composed of a syringe 101 and a piston core rod 102, in order to collect the OP fluid of cattle and sheep without damaging the pharynx or throat of cattle and sheep, the principle of the syringe 10 can be used in reverse, that is, the suction principle of the syringe 10 is used. In addition, since the collection device uses a combination of the syringe 10, the connector 20, the flexible tube 30 and the OP fluid collection component 40, the collection device also has the practical effect of being portable, which can be convenient for staff to use and carry.

[0092] When collecting OP fluid from cattle and sheep, the flexible tube 30 is inserted into the pharynx or throat of the cattle and sheep. At this time, the OP fluid collection component 40 is also synchronously inserted into the pharynx or throat of the cattle and sheep. When the OP fluid collection component 40 contacts the mucus in the pharynx or throat of the cattle and sheep, the staff pulls the piston core rod 102 outward to make the inner cavity of the syringe 101 in a negative pressure state. Under the action of negative pressure, the OP fluid collection component 40 can suck the mucus in the pharynx or throat of the cattle and sheep through the collection chamber 403. After the mucus enters the collection chamber 403, it can continue to enter the flexible tube 30 under the action of negative pressure, and then enter the syringe 101 through the connector 20. After the mucus enters the syringe 101, the collection of OP fluid from cattle and sheep is completed. In addition, during the process of collecting mucus by the OP fluid collection component 40, the pharynx, throat or tongue root of the cattle and sheep will not be damaged, and the collection process is convenient and quick.

[0093] At the same time, the flexible sampling piece provided on the OP liquid collection component 40 can also cooperate with the collection chamber 403. While the OP liquid collection component 40 absorbs mucus through the collection chamber 403, it can also adhere to the mucus through the flexible sampling piece, thereby further improving the sampling effect on the pharynx or throat of cattle and sheep. In addition, the flexible sampling piece will not cause damage to the pharynx, throat or tongue root of cattle and sheep.

[0094] Furthermore, the connector 20 can be easily removed from the syringe 10, one end of the flexible tube 30 can be easily removed from the connector 20, and the other end can be easily removed from the OP liquid collection component 40, thereby facilitating the replacement of the connector 20, the flexible tube 30, and the OP liquid collection component 40.

[0095] A breathable water-absorbing member is installed in the inner cavity of the syringe 101. The breathable water-absorbing member can absorb the mucus in the syringe 101 without affecting the cooperation between the syringe 101 and the piston core rod 102.

[0096] The breathable absorbent member is a water-absorbing cotton sheet 50, which is placed at the bottom of the inner cavity of the syringe 101, wherein the water-absorbing cotton sheet 50 has a plurality of air-permeable gaps, under the effect of the air-permeable gaps, it is possible to facilitate the flow of air, therefore, when the water-absorbing cotton sheet 50 is placed in the inner cavity of the syringe 101, it will not affect the pulling and drawing movement of the piston core rod 102 on the syringe 101;

[0097] Moreover, the absorbent cotton sheet 50 is a better form of breathable absorbent. After the absorbent cotton sheet 50 absorbs the mucus, the staff will pull out the piston core rod 102 and use tweezers to take out the absorbent cotton sheet 50 in the syringe 101. The absorbent cotton sheet 50 can be placed in a testing instrument, and the cattle and sheep OP fluid in the absorbent cotton sheet 50 can be tested and analyzed by the testing instrument.

[0098] The above different embodiments can be combined, replaced and used in conjunction with each other.

[0099] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
