Description

Technical Field

[0001] The invention relates to the technical field of intravenous injection, and in particular to a device for determining the intravenous injection and blood sampling position of a Northeast Forest Rana and a method for using the device. Background Art

[0002] Blood is a carrier for detecting various physiological and biochemical indicators of the body, evaluating the health parameters of organisms, diagnosing blood parasites, identifying viral and bacterial pathogens, and detecting antibody levels. It plays an irreplaceable and important role in scientific research and clinical diagnosis. Intravenous injection usually refers to a medical method of injecting liquid substances such as blood, liquid medicine, and nutrient solution directly into the vein through the vein. Intravenous injection has the advantages of rapid onset of drug effect, less drug harm, and precise and controllable dosage. It is an indispensable technical means in basic research and clinical applications.

[0003] The Northeast Forest Rana is both a medicine and a food, and is nutritious. With the continuous development and improvement of artificial breeding and reproduction technology in recent years, its scientific breeding and disease prevention and control research has gradually been put on the agenda. However, due to its small size, small heart volume, thin blood vessels, rich body mucus and peritoneal fluid, fast coagulation rate and other physiological characteristics, it is extremely difficult to draw blood from the heart and femoral vein, which is easy to be contaminated and may cause death. Intravenous injection is almost impossible to achieve. To this end, the present invention proposes a device for determining the intravenous injection and blood collection position of the Northeast Forest Rana and a method of using the device to solve the above problems.

[0011] Step S2, the operator inserts the thumb and index finger of the left hand into the first clamping ring and the second clamping ring on both sides of the positioning plate respectively to wear the frog, and adjusts the position so that the frog's right eye and the eardrum are located in the positioning groove of the positioning plate, and uses 75% alcohol to disinfect the position between the frog's right eye and the eardrum in the positioning groove;

[0012] Step S3, make one side of the positioning groove at the top of the positioning plate extend from the upper edge of the tympanic membrane to the upper edge of the frog eye, keep the first positioning rod just passing through the center origin of the tympanic membrane, and place the positioning plate, find the first blood collection point where the second positioning rod intersects with the front edge of the tympanic membrane along the second positioning rod, pierce the skin with a blood collection needle, and use a blood collection tube or a capillary tube with a length of 3-4 cm to collect a small amount of blood. After collection, press the pinhole caused by the acupuncture with a 75% alcohol cotton ball to stop bleeding and disinfect;

[0013] Step S4, make one side of the positioning groove at the bottom end of the positioning plate extend along the lower edge of the tympanic membrane to the lower edge of the frog eye, keep the first positioning rod just through the center origin of the tympanic membrane and place it well, find the second blood collection point along the third positioning rod where it intersects with the lower front edge of the tympanic membrane, pierce the skin with a blood collection needle, use a blood collection tube to collect a large amount of blood, or pierce the skin with a syringe and observe the blood returning in the syringe, make sure that the syringe needle has pierced the blood vessel, slowly push the needle tube to complete the intravenous injection, and after the operation is completed, use a 75% alcohol cotton ball to press the pinhole caused by the acupuncture to stop bleeding and disinfect.
