Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-2The utility model provides an embodiment: a blood collection device for hematology, comprising a base 1, an air pump 2 is fixedly connected to one side of the inner part of the base 1, an air inlet pipe 3 is fixedly connected to the output end of the air pump 2, a rubber ring 4 is fixedly connected to the top of the base 1, and one end of the air inlet pipe 3 is fixedly connected to the bottom of the rubber ring 4, an air release pipe 5 is fixedly connected to the outer side of the rubber ring 4, a first electromagnetic valve 6 is fixedly connected to the outer side of the air release pipe 5, and a blood collection table 7 is fixedly connected to the middle of the top surface of the base 1, and the blood collection table 7 is located below the rubber ring 4. When in use, water is first transported to the inside of the blood collection table 7 through the water inlet pipe 12, and then the water can be heated by the heating wire 11, so that the temperature of the blood collection table 7 is increased to prevent the blood collection table 7 from being too cold, and then the arm is placed on the cushion layer 10 placed on the blood collection table 7, and then the air pump 2 is driven to transport gas to the inside of the rubber ring 4 through the air inlet pipe 3, so as to achieve the effect of pressing the arm and facilitate blood collection.

[0031] Reference Figure 2 The inner bottom of the rubber ring 4 is fixedly connected with a support rod 8, and the inside of the rubber ring 4 is set as a hollow structure. The inside of the base 1 is set as a hollow structure, and the air inlet pipe 3 runs through the top of the base 1. By setting the support rod 8, the rubber ring 4 can be prevented from collapsing after deflating, and by setting the rubber ring 4 as a hollow structure, gas can be transported to the inside of the rubber ring 4. By setting the base 1 as a hollow structure, the air pump 2 can be placed inside the base 1, and by the air inlet pipe 3 running through the top of the base 1, the gas can pass through the air inlet pipe 3 and enter the inside of the rubber ring 4.

[0032] Reference Figure 3 , a cushion layer 10 is fixedly connected to the top of the blood collection table 7, and the cushion layer 10 is set as a flexible material. A groove 9 is opened on the top of the blood collection table 7, and the groove 9 is arc-shaped, and the cushion layer 10 is inside the groove 9. The inside of the blood collection table 7 is set as a hollow structure, and a heating wire 11 is fixedly connected to the inside of the blood collection table 7. A water inlet pipe 12 is fixedly connected to the top of one side of the blood collection table 7, and a second solenoid valve 13 is fixedly connected to the outside of the water inlet pipe 12. A water outlet pipe 14 is fixedly connected to the bottom of one side of the blood collection table 7, and a third solenoid valve 15 is fixedly connected to the outside of the water outlet pipe 14. By setting the cushion layer 10, and setting the cushion layer 10 as a flexible material, comfort can be increased during blood collection. Through the groove 9, the arm can be placed in the groove 9 during blood collection. By setting the blood collection table 7 as a hollow structure, water can be filled inside the blood collection table 7, and the water inside the blood collection table 7 can be heated by the heating wire 11, thereby preventing the blood collection table 7 from being too cold. Water can be transported to the inside of the blood collection table 7 through the water inlet pipe 12, and the water inside the blood collection table 7 can be discharged through the water outlet pipe 14. The second solenoid valve 13 and the third solenoid valve 15 can prevent the water inside the blood collection table 7 from flowing out through the water inlet pipe 12 or the water outlet pipe 14 when the blood collection table 7 is in use.

[0033] Reference Figure 1 A placement frame 16 is fixedly connected to one side of the top of the base 1, and a plurality of through holes 17 are provided on the top of the placement frame 16. Through the placement frame 16 and the plurality of through holes 17, the test tube after blood collection can be placed on the placement frame 16 to avoid collapse, and it can avoid the need for medical staff to hold the test tube in their hands all the time, which is inconvenient to operate.

[0034] Working principle: When in use, firstly deliver water to the inside of the blood collection platform 7 through the water inlet pipe 12, then close the second solenoid valve 13, and heat the water inside the blood collection platform 7 through the heating wire 11 inside the blood collection platform 7, so that the temperature of the blood collection platform 7 is increased to avoid the blood vessels from contracting due to the blood collection platform 7 being too cold, thereby increasing the difficulty of blood collection, and then let the patient who needs blood collection place his arm on the cushion layer 10 set on the blood collection platform 7. The cushion layer 10 is relatively soft, which can improve the comfort of the blood collector. When the arm is placed, the air pump 2 is driven to deliver gas to the rubber ring 4 through the air inlet pipe 3, and the rubber ring 4 continues to expand, so as to achieve the effect of comfort for the arm of the blood collector. Squeeze, when the needle is inserted into the arm, the first solenoid valve 6 is opened to allow the gas inside the rubber ring 4 to be discharged through the vent pipe 5, and the rubber ring 4 with the gas discharged slowly collapses. At this time, the support rod 8 arranged inside the rubber ring 4 can support the rubber ring 4 to prevent the rubber ring 4 from collapsing on the blood collection table 7 and affecting the blood collection personnel. The test tube after blood collection can be placed in the through hole 17 of the placement frame 16 arranged above the base 1 to avoid the need for medical staff to hold the test tube in their hands throughout the process, which is inconvenient to operate. After blood collection, the third solenoid valve 15 is opened to allow the water inside the blood collection table 7 to be discharged through the water outlet pipe 14, and then the third solenoid valve 15 can be closed.
