Technical Field

[0001] The present invention relates to the field of blood collection, and more specifically to an anti-hemolysis blood sample collection device for a physical examination center. Background Art

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0017] In the above scheme, by providing a guide block and a shunt block, when it is necessary to make the blood flow slowly down from the inner wall of the blood storage vessel, the blood enters the blood storage vessel through the needle, flows into the cavity on the shunt block, and is allowed to flow out evenly through the multiple shunt ports and shunt holes on the shunt block. The blood flows dispersedly to the surface of the guide block through the multiple shunt ports and shunt holes, and the blood flows outward toward the wall of the blood storage vessel through the inclined surface of the guide block. The blood is guided to flow slowly into the blood storage vessel for storage through the multiple vertical grooves, so that the blood flows evenly, reducing the impact force on the blood during the flow process, and avoiding the hemolysis caused by the rupture of red blood cells due to excessive pressure. At the same time, flowing along the multiple vertical grooves also helps to reduce the direct contact between blood and air, reducing the risk of oxidative hemolysis.

[0018] By providing the vertical rod and the annular liquid bag, when the anticoagulant needs to be uniformly added to the blood, the blood flows into the blood storage tube through the vertical groove. Since the density of the blood is greater than that of the anticoagulant, the blood can drive the annular liquid bag, so that the annular liquid bag rises as the blood increases. In the process of the annular liquid bag rising, as the diameter of the vertical rod becomes larger and larger, the vertical rod squeezes the annular liquid bag more, so that the pressure of the anticoagulant in the annular liquid bag is greater, and the anticoagulant is squeezed into the liquid outlet tube. Under the pressure applied to the annular liquid bag, the anticoagulant pushes the sealing ball away from the sealing port on the truncated table, and the elastic rope stretches. When the sealing ball is pushed away, the anticoagulant can flow out through the gap between the sealing port and the sealing ball, and be uniformly discharged into the blood through multiple liquid outlet tubes.

[0019] By providing an annular airbag, when the needle holder needs to be fixed, the needle holder is put on the outside of the plastic cap so that the top ends of the four connecting rods are in contact with the inner top wall of the needle holder. Then, the needle holder is pressed downward, and the needle holder pushes the connecting rod, which drives the extrusion circular ring plate to slide downward on the plastic cap. When the extrusion circular ring plate slides to contact the annular airbag, the extrusion circular ring plate can squeeze the annular airbag, so that the annular airbag expands outward to fit closely with the inner wall of the needle holder. The friction between the annular airbag and the needle holder can be increased by the rubber pad on the outer surface of the annular airbag, so as to fix the needle holder.

[0020] By providing a suction cup, when the stability of the device needs to be improved, the two second T-shaped sliders at the upper end of the circular plate are respectively inserted into the rectangular grooves on the circular block, and then the circular plate is rotated to rotate the second T-shaped slider into the arc groove, and the second T-shaped slider is rotated to the end of the arc groove. When the second T-shaped slider contacts the rubber block, the second T-shaped slider can squeeze the rubber block to compress the rubber block. When the second T-shaped slider completely leaves the rubber block, the rubber block rebounds to restrict the second T-shaped slider and the suction cup. The device is fixed on the plane through the adsorption force of the suction cup to prevent tipping due to accidental collision or external force, thereby ensuring stability and safety during storage.

[0041] like Figures 1 to 11 As shown, an embodiment of the present invention provides an anti-hemolysis blood sample collection device for a physical examination center, including a blood storage blood vessel 101, a plastic cap 102 is provided at the upper end of the blood storage blood vessel 101, a guide block 103 is provided in the blood storage blood vessel 101, and the guide block 103 is umbrella-shaped. The inner wall of the blood storage blood vessel 101 is provided with a plurality of vertical grooves 104, and the screenshots of the plurality of vertical grooves 104 are all arc-shaped. A shunt component for shunting blood is provided in the blood storage blood vessel 101.

[0042] When the blood needs to flow slowly down the inner wall of the blood storage tube 101, the blood enters the blood storage tube 101 through the needle, and the blood flows to the surface of the guide block 103 through the shunt component. The blood flows to the wall of the blood storage tube 101 through the guide block 103, and the blood is guided by the multiple vertical grooves 104 to flow slowly into the blood storage tube 101 for storage, thereby reducing the impact force on the blood during the flow process, avoiding hemolysis caused by the rupture of red blood cells due to excessive pressure, and at the same time, flowing along the multiple vertical grooves 104 also helps to reduce the direct contact between blood and air, reducing the risk of oxidative hemolysis.

[0043] like Figure 3 As shown, the shunt assembly includes a shunt block 201, which is fixedly connected to the inner wall of the blood storage blood vessel 101, and the top of the guide block 103 is fixedly connected to the shunt block 201. The shunt block 201 is inverted cone shape, and a cavity 202 is provided in the middle of the shunt block 201. A plurality of shunt ports 203 are provided at the lower end of the shunt block 201, and the plurality of shunt ports 203 are all arranged in a circle. A plurality of shunt holes 204 are provided on the shunt block 201, and the plurality of shunt holes 204 are all circular.

[0044] When the blood needs to flow evenly onto the surface of the guide block 103, the blood enters the blood storage blood vessel 101 through the needle, flows into the cavity 202 on the shunt block 201, and is allowed to flow out evenly through the multiple shunt ports 203 and shunt holes 204 on the shunt block 201. The blood flows dispersedly to the surface of the guide block 103 through the multiple shunt ports 203 and shunt holes 204, and flows outward toward the wall of the blood storage blood vessel 101 through the inclined surface of the guide block 103. The blood is guided by the multiple vertical grooves 104 to flow slowly into the blood storage blood vessel 101 for storage, so that the blood flows evenly. The shunt block 201 can also prevent the needle from being pierced off-center, which causes the blood to not flow evenly into the vertical grooves 104.

[0045] like Figure 4 As shown, the inner bottom wall of the blood storage tube 101 is fixedly connected with a vertical rod 205, and the diameter of the vertical rod 205 increases from bottom to top. An annular liquid capsule 206 is arranged on the outside of the vertical rod 205. The annular liquid capsule 206 is circular in shape and is sleeved on the outside of the vertical rod 205. A plurality of circular holes 207 are opened at the lower end of the annular liquid capsule 206. The plurality of circular holes 207 are all arranged in a circle. A liquid outlet pipe 208 is fixedly connected to the inner wall of the circular hole 207. The liquid outlet pipe 208 is communicated with the annular liquid capsule 206, and a sealing component is arranged inside the liquid outlet pipe 208.

[0046] When the anticoagulant needs to be evenly added to the blood, when the blood flows into the blood storage tube 101 through the vertical groove 104, since the density of blood is greater than that of the anticoagulant, the blood can drive the annular liquid sac 206, causing the annular liquid sac 206 to rise as the amount of blood increases. During the rising process of the annular liquid sac 206, as the diameter of the vertical rod 205 becomes larger and larger, the vertical rod 205 squeezes the annular liquid sac 206 more, so that the pressure of the anticoagulant in the annular liquid sac 206 increases, and the anticoagulant is squeezed into the liquid outlet tube 208. The anticoagulant in the annular liquid sac 206 can push open the sealing component in the liquid outlet tube 208, and the anticoagulant is evenly discharged through the multiple liquid outlet tubes 208 on the annular liquid sac 206.

[0047] like Figure 5 As shown, the sealing assembly includes a truncated cone 209, which is fixedly connected to the inner wall of the liquid outlet pipe 208. A sealing opening 210 is opened on the truncated cone 209. A sealing ball 211 is engaged with the inner wall of the sealing opening 210. Two elastic ropes 212 are fixedly connected to the outer surface of the sealing ball 211. The top ends of the two elastic ropes 212 are fixedly connected to the inner wall of the liquid outlet pipe 208.

[0048] When the anticoagulant needs to be evenly added to the blood, the blood flows into the blood storage tube 101 through the vertical groove 104. Since the density of blood is greater than that of anticoagulant, the blood can drive the annular liquid capsule 206, so that the annular liquid capsule 206 rises with the increase of blood. In the process of the annular liquid capsule 206 rising, as the diameter of the vertical rod 205 becomes larger and larger, the vertical rod 205 squeezes the annular liquid capsule 206 more, so that the pressure of the anticoagulant in the annular liquid capsule 206 increases, and the anticoagulant is squeezed into the liquid outlet tube 208. Under the pressure on the annular liquid capsule 206 The anticoagulant pushes the sealing ball 211 away from the sealing port 210 on the truncated cone 209, and the elastic rope 212 is stretched. While the sealing ball 211 is pushed away, the anticoagulant can flow out through the gap between the sealing port 210 and the sealing ball 211, and be evenly discharged into the blood through multiple liquid outlet pipes 208. After the anticoagulant flows out, the elastic rope 212 rebounds, and the elastic rope 212 drives the sealing ball 211, so that the sealing ball 211 is engaged with the sealing port 210, and the truncated cone 209 is sealed to prevent impurity blood from entering the annular liquid bag 206 through the liquid outlet pipe 208.

[0049] like Figure 6 As shown, the outer surface of the plastic cap 102 is provided with an annular airbag 213, and the annular airbag 213 is sleeved on the outside of the plastic cap 102. The outer surface of the annular airbag 213 is fixedly connected with a rubber pad 214. The plastic cap 102 is provided with an extrusion component for extruding the annular airbag 213.

[0050] By providing an annular airbag 213 and a rubber pad 214, the annular airbag 213 can be squeezed by an extrusion component to expand the annular airbag 213 outward, and the outer surface of the annular airbag 213 fits tightly with the inner wall of the needle holder. The rubber pad 214 on the outer surface of the annular airbag 213 can increase the friction between the annular airbag 213 and the needle holder, thereby fixing the needle holder.

[0051] like Figure 7 As shown, the extrusion assembly includes a fixed annular plate 215, which is fixedly connected to the outer surface of the plastic cap 102, and the annular airbag 213 is located at the top of the fixed annular plate 215. The outer surface of the plastic cap 102 is slidably connected with an extrusion annular plate 216, and the top of the extrusion annular plate 216 is fixedly connected with four connecting rods 217, and the four connecting rods 217 are all arranged in a circle.

[0052] When the needle holder needs to be fixed, the needle holder is put on the outside of the plastic cap 102 so that the top ends of the four connecting rods 217 are in contact with the inner top wall of the needle holder. Then, the needle holder is pressed downward, and the needle holder pushes the connecting rod 217. The connecting rod 217 drives the extrusion ring plate 216 to slide downward on the plastic cap 102. When the extrusion ring plate 216 slides to contact the annular airbag 213, the extrusion ring plate 216 can squeeze the annular airbag 213, so that the annular airbag 213 expands outward to fit closely with the inner wall of the needle holder. The rubber pad 214 on the outer surface of the annular airbag 213 can increase the friction between the annular airbag 213 and the needle holder, thereby fixing the needle holder.

[0053] like Figure 7 and Figure 8 As shown, two first T-shaped sliders 218 are fixedly connected to one side of the extrusion annular plate 216 close to the plastic cap 102 , and two second T-shaped sliding grooves 219 are provided on the plastic cap 102 . Both of the first T-shaped sliders 218 are slidably connected in the corresponding two sliding grooves.

[0054] By providing a first T-shaped slider 218 and a second T-shaped groove 219, when the extrusion annular plate 216 is moving, the extrusion annular plate 216 can drive the first T-shaped slider 218 to slide in the second T-shaped groove 219. The second T-shaped groove 219 can guide and limit the first T-shaped slider 218 and the extrusion annular plate 216. The first T-shaped slider 218 slides in the second T-shaped groove 219, which can also improve the stability of the extrusion annular plate 216 during movement.

[0055] like Fig. 9 As shown, a plurality of connection ropes 220 are fixedly connected to the inner top wall of the annular liquid capsule 206 , and a round ball 221 is fixedly connected to the bottom ends of the plurality of connection ropes 220 , and the connection ropes 220 and the round ball 221 are both arranged in a circle.

[0056] When the annular liquid capsule 206 is in the process of rising, the gravity of the ball 221 can drive the connecting rope 220 to swing back and forth, and the anticoagulant in the annular liquid capsule 206 can be evenly mixed during the swinging of the ball 221.

[0057] like Fig.10 As shown, a round block 222 is fixedly connected to the bottom end of the blood storage tube 101, a round groove 223 is provided in the middle of the round block 222, a round plate 224 is provided on the inner wall of the round groove 223, a suction cup 225 is fixedly connected to the bottom end of the round plate 224, and a disassembly component for disassembling and assembling the suction cup 225 is provided on the round block 222.

[0058] By providing the suction cup 225, when the device is being transported, the device can be firmly fixed on a plane through the adsorption force of the suction cup 225 to prevent tipping due to accidental collision or external force, thereby ensuring stability and safety during storage.

[0059] like Fig.11 As shown, the disassembly assembly includes two second T-shaped sliders 226, and the two second T-shaped sliders 226 are fixedly connected to the top of the circular plate 224. The inner wall of the circular block 222 is provided with a rectangular groove 227 and an arc groove 228 that cooperate with the second T-shaped sliders 226. The rectangular groove 227 is connected to the arc groove 228, and the inner wall of the arc groove 228 is fixedly connected with two rubber blocks 229.

[0060] When the suction cup 225 needs to be installed, the two second T-shaped sliders 226 at the upper end of the circular plate 224 are respectively inserted into the rectangular grooves 227 on the circular block 222. Then, the circular plate 224 is rotated to rotate the second T-shaped sliders 226 into the arc groove 228. The second T-shaped sliders 226 are rotated to the end of the arc groove 228. When the second T-shaped sliders 226 contact the rubber block 229, the second T-shaped sliders 226 can squeeze the rubber block 229 to compress the rubber block 229. When the second T-shaped sliders 226 are completely When the rubber block 229 is completely separated from the rubber block 229, the rubber block 229 rebounds to restrict the second T-shaped slider 226, and the suction cup 225 is installed. When the suction cup 225 needs to be removed, the circular plate 224 is rotated in the opposite direction, and the second T-shaped slider 226 squeezes the rubber block 229 to compress the rubber block 229. The circular plate 224 drives the second T-shaped slider 226 to slide from the arc groove 228 to the rectangular groove 227. Then, the circular plate 224 is pulled downward to make the second T-shaped slider 226 leave the rectangular groove 227, and the suction cup 225 is removed.

[0061] The working process of the technical solution provided by the present invention is as follows:

[0062] When in use, the needle holder is put on the outside of the plastic cap 102 so that the top ends of the four connecting rods 217 contact the inner top wall of the needle holder. Then, the needle holder is pressed downward, and the needle holder pushes the connecting rod 217. The connecting rod 217 drives the extrusion annular plate 216 to slide in the plastic cap 102. The extrusion annular plate 216 drives the first T-shaped slider 218 to slide downward in the second T-shaped slide groove 219. When the extrusion annular plate 216 slides to contact the annular airbag 213, the extrusion annular plate 216 can squeeze the annular airbag 213, so that the annular airbag 213 expands outward to fit closely with the inner wall of the needle holder. The rubber pad 214 on the outer surface of the annular airbag 213 can increase the friction between the annular airbag 213 and the needle holder, thereby fixing the needle holder.

[0063] Subsequently, the blood enters the blood storage vessel 101 through the needle on the needle holder, flows into the cavity 202 on the shunt block 201, and is allowed to flow out evenly through the multiple shunt ports 203 and shunt holes 204 on the shunt block 201. The blood is dispersed to the surface of the guide block 103 through the multiple shunt ports 203 and shunt holes 204, and the blood flows outward to the wall of the blood storage vessel 101 through the inclined surface of the guide block 103. The blood is guided by the multiple vertical grooves 104 to flow slowly into the blood storage vessel 101 for storage. When the blood flows into the blood storage vessel 101 through the vertical grooves 104, since the density of the blood is greater than the density of the anticoagulant, the blood can drive the annular liquid capsule 206, so that the annular liquid capsule 206 rises as the amount of blood increases. In the process of the annular liquid capsule 206 rising, as the diameter of the vertical rod 205 becomes larger and larger, the vertical rod 205 squeezes the annular liquid capsule 206 more, so that the pressure of the anticoagulant in the annular liquid capsule 206 is greater, and the annular liquid capsule 206 is The anticoagulant is squeezed into the liquid outlet pipe 208. Under the pressure exerted on the annular liquid capsule 206, the anticoagulant pushes the sealing ball 211 away from the sealing port 210 on the truncated cone 209. The elastic rope 212 is stretched. When the sealing ball 211 is pushed away, the anticoagulant can flow out through the gap between the sealing port 210 and the sealing ball 211, and be evenly discharged into the blood through multiple liquid outlet pipes 208. After the anticoagulant flows out, the elastic rope 212 rebounds. The elastic rope 212 drives the sealing ball 211 to engage with the sealing port 210, thereby sealing the truncated cone 209 and preventing impurity blood from entering the annular liquid capsule 206 through the liquid outlet pipe 208. In the process of the annular liquid capsule 206 rising, the round ball 221 is also driven. The gravity of the round ball 221 can drive the connecting rope 220 to swing back and forth. During the swinging of the round ball 221, the anticoagulant in the annular liquid capsule 206 can be evenly mixed.

[0064] When the suction cup 225 needs to be installed, the two second T-shaped sliders 226 at the upper end of the circular plate 224 are respectively inserted into the rectangular grooves 227 on the circular block 222. Then, the circular plate 224 is rotated to rotate the second T-shaped slider 226 into the arc groove 228. The second T-shaped slider 226 is rotated to the end of the arc groove 228. When the second T-shaped slider 226 contacts the rubber block 229, the second T-shaped slider 226 can squeeze the rubber block 229 to compress the rubber block 229. When the second T-shaped slider 226 completely leaves the rubber block 229, the rubber block 229 rebounds to press the second T-shaped slider 226. Restriction, the suction cup 225 is installed. Through the adsorption force of the suction cup 225, the device can be firmly fixed on the plane to prevent tipping due to accidental collision or external force, thereby ensuring stability and safety during storage. When the suction cup 225 needs to be disassembled, the circular plate 224 is rotated in the opposite direction, and the second T-shaped slider 226 squeezes the rubber block 229 to compress the rubber block 229. The circular plate 224 drives the second T-shaped slider 226 to slide from the arc groove 228 to the rectangular groove 227. Then, the circular plate 224 is pulled downward to make the second T-shaped slider 226 leave the rectangular groove 227, and the suction cup 225 is disassembled.
