[0002] Animal blood collection is a routine operation in animal husbandry, veterinary medicine and animal experiments, and is widely used in disease diagnosis, health monitoring and scientific research; currently, blood collection techniques mainly rely on manual operations, supplemented by standardized needles of different specifications (such as conventional blood collection needles, butterfly needles, insulin needles, etc.) and blood collection tubes, etc.
[0003] However, during the traditional animal blood collection process, the operator usually needs to maintain a specific blood collection posture for a long time (for example, when collecting blood from the jugular vein of cattle, a 30° inclination angle needs to be maintained for 1 - 3 minutes), which easily causes muscle fatigue and excessive burden on the operator. Especially when collecting blood from large animals such as cattle and horses, multiple people are required to cooperate, resulting in low efficiency. At the same time, the risk brought by animal resistance is relatively large. For example, animals may kick or struggle due to pain or fear, resulting in needle displacement or detachment, and even accidental needle puncture, animal collision and other situations that may injure the operator. In addition, the uneasiness and restlessness of animals may further increase the difficulty of blood collection.
[0004] Therefore, it is particularly necessary to develop a portable animal blood collection device.

[0018] (1) The clamping component provided in the present invention can clamp the protective sleeve and the vacuum blood collection tube arranged therein. After the operator completes the puncture, he can leave the animal, and the blood collection will be carried out automatically. Before blood collection, first place the vacuum blood collection tube in the protective sleeve, pass the blood collection hose connected to the top of the vacuum blood collection tube through the protective sleeve arranged at the top of the protective sleeve, and then adjust the relative position of the vacuum blood collection tube and the fixed seat. After the protective sleeve is flush with the upper surface of the fixed seat, rotate the control sleeve rotatably clamped on the fixed seat, so that the control sleeve drives the screw sleeve screwed therein to move axially, so that the screw sleeve presses the connecting ring, and the connecting ring will slide along the orientation groove with the sliding sleeve. Since the sliding sleeve contacts the wedge block through an inclined surface, and at the same time the wedge block is slidably clamped between the guide frames through the limiting groove, when the sliding sleeve moves, it will drive the wedge block to move inward along the guide frame, so that the inner side of the wedge block clamps the protective sleeve through a pair of splint plates connected by elastic plates, and then open the insurance component to further fix the protective sleeve.
[0019] (2) The insurance component provided in the present invention can prevent the vacuum blood collection tube from falling midway due to the struggle of the animal during blood collection. After the vacuum blood collection tube is fixed by the clamping component, slide the pressing plate along the chute, so that the side plate moves in the chute until the side plate moves into the fixed ring, and then rotate the pressing plate along the fixed ring, so that one side of the pressing plate contacts the stopper arranged in the fixed ring, and then manually pull the pull ring arranged outside the locking shaft, so that the locking shaft moves out of the locking shaft opened on the fixed frame, and then rotate the fixed frame along the fixed block, so that the pressing plate slidably clamped on the fixed frame through the chute presses against the outside of the protective sleeve to complete the auxiliary fixation of the vacuum blood collection tube.
[0020] (3) The separation component provided in the present invention can relax the clamping force of the clamping component, so that the blood in the vacuum blood collection tube will fall automatically after reaching the blood collection volume standard. After the blood in the vacuum blood collection tube reaches the blood collection volume standard, the transmitter will synchronously send a signal to the electromagnet connected to the top of the fixed seat, convert the magnetic pole of the electromagnet, so that the electromagnet repels the two connecting arms, and the two connecting arms will move outward synchronously along the cross bar and pull the connecting button arranged outside the splint plate, so that the splint plate relaxes the protective sleeve to release the vacuum blood collection tube.

Detailed implementation manners
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners:
[0028] Embodiment:
[0029] As Figures 1 to 5 shown, the present invention provides a portable animal blood collection device, including a fixing seat 37. A protective sleeve 1 clamped by a clamping assembly is arranged in the fixing seat 37. A vacuum tube for blood collection is arranged in the protective sleeve 1. The top end of the vacuum tube for blood collection is connected with a blood collection hose 2. The blood collection hose 2 is clamped on a protective sleeve 7 sleeved on the top end of the protective sleeve 1. A strap 5 is connected to the outside of the fixing seat 37. A plurality of weight reduction grooves 3 are formed in the strap 5. One end of the strap 5 is fixedly provided with a connecting frame 6. The free end of the strap 5 passes through the connecting frame 6. A pressure roller 4 is arranged on the outside of the free end of the strap 5. The outside of the strap 5 is in frictional contact with the pressure roller 4.
[0030] As Figure 4 and Figure 5 shown, the clamping assembly includes a sliding sleeve 31 arranged in the fixing seat 37. The bottom end of the sliding sleeve 31 is coaxially connected with a connecting ring 36. A pair of orienting grooves 32 are jointly formed on the inner walls of the sliding sleeve 31 and the connecting ring 36. The sliding sleeve 31 is slidably clamped in the inner side of the fixing seat 37 through the orienting grooves 32. The inner side of the sliding sleeve 31 is an inclined surface.
[0031] As Figure 1 、 Figure 3 and Figure 5 shown, two pairs of guide frames 14 are arranged at one end of the fixing seat 37. A wedge block 13 is arranged between each pair of guide frames 14. Limiting grooves 11 are formed at both ends of the wedge block 13. The wedge block 13 is slidably clamped between the guide frames 14 through the limiting grooves 11. The wedge block 13 is in contact with the sliding sleeve 31 through an inclined surface. The inner side of the wedge block 13 is connected with a clamping plate 17 through a pair of elastic plates 12. The protective sleeve 1 is clamped between the two clamping plates 17.
[0032] As Figure 4 and Figure 5 shown, a screw sleeve 34 is rotatably clamped at the bottom end of a connecting ring 36. A control sleeve 35 is screwed on the outer side of the screw sleeve 34. The control sleeve 35 is rotatably clamped at one end of a fixed seat 37.
[0033] As Figure 3 and Figure 5 shown, a separating assembly is arranged on the fixed seat 37. The separating assembly includes an electromagnet 19 connected to the top end of the fixed seat 37. Cross bars 18 are connected to both ends of the electromagnet 19. Baffles 15 are arranged at the free ends of the cross bars 18. Connecting arms 9 are penetrated through the cross bars 18. Magnetic blocks are arranged on the opposite sides of the two connecting arms 9.
[0034] As Figure 3 shown, a connecting button 10 is arranged on the outer side of a clamping plate 17. The two connecting arms 9 are respectively sleeved on the outer sides of the two connecting buttons 10.
[0035] The separating assembly can relax the clamping force of the clamping assembly, so that the blood in the blood collection vacuum tube drops automatically after reaching the blood collection volume standard. After the blood in the blood collection vacuum tube reaches the blood collection volume standard, a transmitter will synchronously send a signal to the electromagnet 19 connected to the top end of the fixed seat, converting the magnetic poles of the electromagnet 19, so that the electromagnet 19 repels the two connecting arms 9. The two connecting arms 9 will synchronously move outwards along the cross bars 18 and pull the connecting buttons 10 arranged on the outer side of the clamping plate 17, so that the clamping plate 17 relaxes the protective sleeve 1 to release the blood collection vacuum tube.
[0036] As Figure 4 shown, a safety assembly is arranged on the outer side of the fixed seat 37. The safety assembly includes a fixed block 28 fixedly connected to the outer side of the fixed seat 37. A fixed frame 24 is rotatably clamped on the fixed block 28. A pair of fixing rings 30 are arranged on the fixed frame 24. A pair of sliding grooves 29 are formed on the fixed frame 24. Side plates 26 are slidably clamped in the two sliding grooves 29. The two side plates 26 are connected by a pressing plate 33.
[0037] As Figure 2 and Figure 4 shown, a stop block 25 is arranged in the fixing ring 30. One side of the pressing plate 33 is in contact with the outer side of the protective sleeve 7.
[0038] As Figure 4 shown, a locking shaft 20 is slidably clamped on the outer side of the fixed block 28. The locking shaft 20 is connected to the fixed block 28 through a spring 21. A pull ring 22 is arranged on the outer side of the locking shaft 20. A locking groove 23 is formed on the fixed frame 24. The locking shaft 20 is penetrated through the locking groove 23.
[0039] As Figures 3 to 5 shown, an annular plate 16 connected through a connecting plate 8 is arranged on the fixed seat 37. A light source and a light sensor are oppositely arranged on the inner side of the annular plate 16. The light sensor controls the movement of the locking shaft 20.
[0040] The insurance component can prevent the blood collection vacuum tube from falling midway during the blood collection process due to the struggling of the animal. After fixing the blood collection vacuum tube through the clamping component, slide the pressing plate 33 along the chute 29 to move the side plate 26 within the chute 29 until the side plate 26 moves into the fixing ring 30. Then, rotate the pressing plate 33 along the fixing ring 30 until one side of the pressing plate 33 contacts the stopper 25 arranged within the fixing ring 30. Then, manually pull the pull ring 22 arranged outside the locking shaft 20 to move the locking shaft 20 out of the locking shaft opening provided on the fixing bracket 24. Then, rotate the fixing bracket 24 along the fixing block 28 to press the pressing plate 33 slidably clamped through the chute 29 on the fixing bracket 24 against the outer side of the protective sleeve 7, and the auxiliary fixation of the blood collection vacuum tube can be completed;
[0041] When the blood in the blood collection vacuum tube reaches the blood collection volume standard, the light sensor will send a signal to the locking shaft 20 to move the locking shaft 20 outward. After the locking shaft 20 disengages from the locking groove 23, the rotation limit of the fixing bracket 24 is released. At the same time, the separating component will relax the clamping force of the clamping component, and the blood collection vacuum tube will squeeze open the pressing plate 33 under the action of gravity, causing the blood collection vacuum tube and the protective sleeve 1 to fall together.
[0042] The specific usage mode and function of this embodiment:
[0043] The clamping component provided in the present invention can clamp the protective sleeve 1 and the blood collection vacuum tube arranged therein. After the operator completes the puncture, the operator can leave the animal, enabling automatic blood collection. Before blood collection, first place the blood collection vacuum tube into the protective sleeve 1, insert the blood collection hose 2 connected to the top of the blood collection vacuum tube into the protective sleeve 7 provided at the top of the protective sleeve 1. Then, adjust the relative position of the blood collection vacuum tube and the fixing seat. After the protective sleeve 7 is flush with the upper surface of the fixing seat, rotate the control sleeve 35 rotatably clamped on the fixing seat to drive the screw sleeve 34 screwed therein to move axially, so that the screw sleeve 34 presses the connecting ring 36, and the connecting ring 36 will slide along the directional groove 32 with the sliding sleeve 31. Since the sliding sleeve 31 contacts the wedge-shaped block 13 through an inclined surface, and at the same time the wedge-shaped block 13 is slidably clamped between the guide frames 14 through the limiting groove 11, when the sliding sleeve 31 moves, it will drive the wedge-shaped block 13 to move inward along the guide frame 14, so that the inner side of the wedge-shaped block 13 clamps the protective sleeve 1 through the pair of elastic plates 12 connected to the clamping plate 17, and then open the insurance component to further fix the protective sleeve 1;
[0044] After the fixation is completed, tie the strap 5 connected to the outside of the fixing base to the limb of the animal to be blood-sampled. After passing the free end of the strap 5 through the connecting frame 6 connected to the other end of the connecting frame 6, fold the free end of the strap 5 outward so that the free end of the strap 5 passes through the bottom of the pressure roller 4 provided on the outside of the free end of the strap 5. Then, drive the pressure roller 4 to rotate and drive the strap 5 to tighten, so that the strap 5 can be tightened to the limb of the animal to be blood-sampled. At this time, puncture the blood collection needle to the blood collection position of the animal to be blood-sampled and fix it, and then automatic blood collection can be carried out through the blood collection vacuum tube.
[0045] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
