The length of the support rod 6 is gradually increased from the head part to the tail part sequentially to form a tail part with a high head part and a low head part.

The binding device 7 is a nylon quick-sticking belt.

The number of the first cross beams 11 is 3, and support rods 6 are arranged below the first cross beams; the number of the second beams 21 is 3, and support rods 6 are arranged below the two second beams close to the head part; the joint of the front blocking frame 1 and the rear blocking frame 2 is fixed by a first cross beam and a second cross beam through bolts 4.

When the pig binding arm is used, the front blocking frame is connected with the rear blocking frame, the contact surface of the first cross beam and the second cross beam is fixedly connected through screws, and then the inserting position of the binding arm is adjusted according to the size of a pig; after the pig is placed on the device, the pig leg is fixed on the binding arm; fixing the pig mouth on a fixing device; after the whole body of the pig is fixed, the pig cannot struggle, so that the hemolysis of the serum is small, and the quality of the serum is ensured.

The device simple structure, it is small, installation and convenient to use, bind struggle little of back pig, and low cost.

Pig serum that uses in the existing market generally derives from the screening in batches of plant or slaughterhouse, and the qualification rate is only about 30%, and this mode shortcoming work load is big, and the quality of serum can't be guaranteed, adopts big container if blood is collected, and the hemolysis can appear in the serum of collection, influences subsequent experimental research and product development.

Some traditional bloodletting methods in the past have large workload and low efficiency for operators. In terms of serum collection amount, blood in a blood vessel cannot be collected completely due to a decrease in blood pressure as the blood slowly flows out, and thus waste is large. In the aspect of serum quality, aseptic collection is difficult to achieve by a traditional mode, and contaminated bacteria easily cause the quality reduction of serum and even the rejection of serum. In addition, in the conventional blood collection mode, certain hemolysis phenomenon exists due to factors such as struggle of a collection object and impact of whole blood, and the quality of serum is also reduced.

In order to solve the above problems, the utility model discloses a special blood sampling device which uses a detachable light folding retaining frame and is matched with the retaining frame, the blood sampling device 9 comprises a blood sampling needle head 92 and a blood pressure sensor 93 which are sequentially arranged on a silica gel blood sampling tube 91, the tail end of the blood sampling needle head passes through a sealing bottle plug 94 and is fixed in a bottle 96 through a blood outlet fixing magnet 95; a bottle rack magnet 97 is arranged outside the bottle 96 and is attracted with the blood vessel fixing magnet 95; the tail end of an air suction pipe on the air suction pump 98 penetrates through the sealing bottle stopper 94 and is positioned in the bottle 96; the bottle 96 is obliquely arranged on the bottle holder 962.

As shown in fig. 3: the blood pressure sensor 93 is further designed, the two ends of the blood pressure sensor are connected with the silica gel for blood sampling, the blood pressure is measured, the measurement result is transmitted to the single chip intelligent controller 99 in a serial port mode, the no-load value is transmitted to the controller as the background number when the system is initialized, and the background number is subtracted from the actual measurement value so as to eliminate the measurement system error. The intelligent controller 99 of the single chip microcomputer is a single chip computer with STM32 as a core, and the interface is a capacitive color serial touch screen, so that man-machine conversation is realized, various parameters are set, such as setting the starting pressure of an air pump, observing the change value of blood pressure at any time, and the like. The controller is also internally provided with a solid-state relay for controlling the air pump 98 to be opened and closed so as to automatically control the whole blood sampling process.

This blood sampling device can be aseptic ground through the pig artery with blood collection, the supplementary draw-out device of vacuum of adding, automatic start when pig blood pressure drops to the maximize gather serum and improved work efficiency. The obtained separated serum has no hemolysis and the serum CCU titer can reach up to 10¹⁰. Through verification and comparison of a plurality of batches of blood-collecting pigs specially bred, the utilization rate of collected serum can reach more than 98%, and the CCU (strain culture Unit) in a laboratory develops color: the titer can reach 10^8-10. Compared with other traditional blood sampling modes, the invention collects the analyzed amount and the quality of the serum; the mycoplasma culture efficiency and the sterility have great advantages. Example 1 comparison of serum deposition amounts, 5 pigs with consistent backgrounds were collected in the same field under the same feeding conditions in the same weight and in the same conventional manner as in the present invention, and the ear plates collected in the conventional manner were designated as Z-1, Z-2, Z-3, Z-4, and Z-5, and the ear plates collected in the present invention were designated as X-1, X-2, X-3, X-4, and X-5, respectively. The serum was treated under the same conditions to compare the amount of serum released. The results are shown in Table I.

EXAMPLE 3 sterile comparison

The serum collected in two different ways was subjected to sterility test in each batch (refer to the pharmacopoeia of the people's republic of China (2015 edition three). The observation of 7 days of detection and culture, the result of new equipment and new mode of serum collection for TG and TSB detection are aseptic growth, and the result is: negative (—). And the traditional method for collecting serum to detect TG and TSB results have bacterial growth, and the results are as follows: positive (+). The results are shown in Table III

Serum sterility test record table three

After long-time breeding and cultivation, the value of the animal serum is very high, so that the method is very important for the production and preparation of the full-negative serum, and the conventional bloodletting method adopted at present cannot maximally collect the animal serum; when the heart of the pig beats weakly, the bleeding becomes very slow, and the arterial blood can not be output cleanly.

The utility model discloses possible whole blood sampling process aseptic to whole blood sampling process does not have by a wide margin blood and rocks, can make the hemolysis of serum less, has guaranteed the quality of serum, the utility model discloses a put the frame to one side of triangular flask, magnetism blood vessel fixer can make the blood that gets into the triangular flask slowly flow in the bottle along the bottle wall, has reduced the disturbance to blood, makes the quality of serum better.
