With the continuous improvement of animal epidemic prevention level, the livestock and poultry disease monitoring laboratory work has rapidly developed in the grass-roots animal epidemic prevention departments. The development of monitoring work requires a large amount of serum, and blood sampling is the main technical means to obtain serum. Animal blood collection is an important routine and prerequisite work, and the grass-roots veterinarians must master the correct and rapid blood collection operation technology.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figures 1-3 The utility model provides the following technical scheme: a blood sampling tool special for veterinarians, which comprises a syringe composed of a needle cylinder 1, an injection needle 2 and a piston rod 3.

[0025] The piston rod 3 is slidingly connected in the interior of the needle cylinder 1, and the injection needle 2 is mounted on the needle head of the needle cylinder 1 in a plug-in manner.

[0026] The needle head of the needle cylinder 1 is provided with the needle plug 6 mounted in a plug-in manner and the cylinder plug 5 mounted in a plug-in manner at the other end, and one end of the piston rod 3 is provided with the anti-skid convex point 4; when in use, the syringe composed of the needle cylinder 1, the injection needle 2 and the piston rod 3 can be used to draw blood from livestock.

[0027] After blood sampling is completed, first, the needle cylinder 1 is turned over so that the direction of the injection needle 2 is downward, then the piston rod 3 is pulled out, and the cylinder plug 5 is inserted into the other end of the needle cylinder 1, so that the needle cylinder 1 is closed to prevent blood from spilling, and then the needle cylinder 1 is turned over upward so that the direction of the injection needle 2 is upward, at this time, the blood in the interior of the needle cylinder 1 moves toward the cylinder plug 5.

[0028] After completion, the injection needle 2 can be pulled out, and the needle plug 6 is inserted into the needle head on the needle cylinder 1, so that the needle cylinder 1 is sealed, which avoids the need to inject blood into the interior of the vacuum tube every time blood sampling is performed, thereby reducing material consumption and improving blood sampling efficiency and safety. Through this way, the veterinarian can more conveniently perform blood collection work on livestock, and ensure smooth blood sampling process.

[0029] Specifically, as shown in the figure, Figure 3 In this embodiment, the cylinder plug 5 and the needle plug 6 are both conical in shape; this design enables the cylinder plug 5 and the needle plug 6 to closely fit the two ends of the needle cylinder 1, thereby effectively preventing blood leakage, and the conical shape not only increases the sealing property, but also makes insertion and pulling out more smooth.

[0030] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , in the embodiment, the outer wall of the barrel plug 5 is fixed with a pair of second connecting plates 8, one end of the needle plug 6 is fixed with a first connecting plate 7, a pair of mounting grooves 9 are formed on the second connecting plate 8 and the first connecting plate 7, two pairs of screw rods 11 for penetrating the two pairs of mounting grooves 9 are fixed on the outer wall of the needle barrel 1, the outer wall of the two pairs of screw rods 11 is threadedly installed with a nut 12, and the two pairs of screw rods 11 are also fixed with a gasket 13; during use, when the barrel plug 5 and the needle plug 6 are inserted into the corresponding positions of the needle barrel 1, the first connecting plate 7 and the second connecting plate 8 can be hung on the screw rod 11 through the mounting groove 9, and the purpose of this is to ensure that one side of the first connecting plate 7 and the second connecting plate 8 can be tightly attached to the gasket 13, so as to achieve better sealing effect, and then the nut 12 is firmly installed on the screw rod 11 by rotating, and in this way, the nut 12 and the gasket 13 jointly act on the first connecting plate 7 or the second connecting plate 8 to effectively clamp the first connecting plate 7 or the second connecting plate 8, and such clamping action can ensure that the barrel plug 5 and the needle plug 6 are firmly fixed on the needle barrel 1, thereby significantly improving the sealing performance of the needle barrel 1, so that even during transportation, the needle barrel 1 is not easy to cause blood overflow, and the safety and integrity of the blood sample are ensured.

[0031] Specifically, as shown in Figure 2 , in the embodiment, the second connecting plate 8 and the first connecting plate 7 are both fixed with a pull ring 10; when blood is needed, the barrel plug 5 or the needle plug 6 can be pulled out of the needle barrel 1 by pulling the pull ring 10, and the design of the pull ring 10 makes the operation more convenient and fast, especially when the blood sample needs to be quickly obtained, in addition, the use of the pull ring 10 reduces the direct contact with the needle barrel 1, and reduces the risk of contaminating the blood sample.

[0032] Specifically, as shown in Figure 2 , in the embodiment, the outer wall of the second connecting plate 8 and the first connecting plate 7 is provided with an anti-skid pattern 14; the stability of the nut 12 and the gasket 13 in clamping the first connecting plate 7 or the second connecting plate 8 can be increased, so that it is not easy to slide.

[0033] The components not described in detail herein are prior art.

[0034] The working principle and use process of the utility model are as follows: when used, the syringe composed of the needle barrel 1, the injection needle 2 and the piston rod 3 can be used to draw blood from livestock;

[0035] After blood sampling is completed, first, the syringe 1 is turned upside down, so that the injection needle 2 is directed downward, then the plunger rod 3 is pulled out, the barrel plug 5 is inserted into the other end of the syringe 1, so that the syringe 1 is sealed to prevent blood from spilling, then the syringe 1 is turned upside down, so that the injection needle 2 is directed upward, at this time, the blood in the syringe 1 moves towards the barrel plug 5;

[0036] After completion, the injection needle 2 can be pulled out, and the needle plug 6 is inserted into the needle on the syringe 1, so that the syringe 1 is sealed, which avoids the need to inject blood into the vacuum tube every time blood is collected, thereby reducing material consumption and improving blood collection efficiency and safety, so that veterinarians can more conveniently collect blood from livestock, ensuring smooth blood collection process;

[0037] When the barrel plug 5 and the needle plug 6 are inserted into the corresponding positions of the syringe 1, the first connecting piece 7 and the second connecting piece 8 can be hung on the screw rod 11 through the mounting groove 9, which is to ensure that one side of the first connecting piece 7 and the second connecting piece 8 can be tightly attached to the gasket 13, thereby achieving better sealing effect, then the screw cap 12 is firmly installed on the screw rod 11 by rotating, in this way, the screw cap 12 and the gasket 13 work together to effectively clamp the first connecting piece 7 or the second connecting piece 8, which can ensure that the barrel plug 5 and the needle plug 6 are firmly fixed on the syringe 1, thereby significantly improving the sealing performance of the syringe 1, so that the syringe 1 is not easy to spill blood during transportation, ensuring the safety and integrity of the blood sample.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
