Hemospast for animal husbandry and veterinary medicine

Abstract

The invention discloses a hemospast for animal husbandry and veterinary medicine, and relates to the technical field of medical supplies, in particular to the hemospast for animal husbandry and veterinary medicine, which comprises a needle cylinder, a piston is inserted into the needle cylinder, one side of the piston is fixedly connected with a drawing rod, one end of the drawing rod far away from the piston is fixedly connected with a drawing plate, the lower surface of the needle cylinder is fixedly connected with a connecting pipe, the end, away from the needle cylinder, of the connecting pipe is in threaded connection with a liquid storage cylinder, and a valve is arranged on the outer surface of the connecting pipe. According to the hemospast for the animal husbandry and veterinary medicine, due to the arrangement of the liquid storage cylinder, in the using process, extracted blood can be stored, so that a storage tool does not need to be additionally found; the connecting pipe is in threaded connection with the liquid storage cylinder, so that the liquid storage cylinder is convenient to replace, the purpose of convenient use is achieved; and through the arrangement of a handle, it is convenient for the staff to hold the hemospast for animal husbandry and veterinary medicine in the process of liquid extraction, so as to prevent the falling off of the hemospast.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a blood drawer for animal husbandry and veterinary medicine. Background technique [0002] Blood draws are often required in animal husbandry work. In the past practice, traditional syringes were generally used, which was inconvenient to use because the operator had to pull the lever of the syringe all the time after inserting the needle to draw out the blood. Later, someone designed a vacuum tube with negative pressure inside the tube to hold the drawn blood, and the vacuum tube was separated from the blood collection device. When in use, the staff first pierce the needle into the blood vessel, and then use the vacuum puncture needle at the other end to pierce the entrance of the vacuum tube. Driven by the negative pressure in the tube, the blood flows from the blood vessel into the vacuum tube. This kind of device is easy to use and has been applied in a large area n...

AI Technical Summary

Problems solved by technology

This kind of device is easy to use and has been applied in a large area now, but the disadvantage of this device is that due to the small entrance on the vacuum tube, it is not easy for the operator to pierce the vacuum puncture needle into the blood vessel when the blood collection needle has already been inserted into the blood vessel. Vacuum tubes, especially when the animal is struggling due to pain, are more likely to cause prolonged blood draw time. In addition, because the operator needs to free up to insert the vacuum puncture needle into the vacuum tube, it often causes the blood collection needle to penetrate the vessel wall
