Description

Technical Field

[0001] This invention relates to the field of blood sampling technology, and more particularly to a blood sampling device for use in medical hematology departments. Background Technology

[0002] Doctors often need patients' blood test reports to aid in their diagnosis, requiring patients to undergo blood draws first. Many patients with blood disorders also require frequent blood tests. The current procedure involves attaching an elastic band to the patient's arm to expose the veins, having the patient clench their fist, disinfecting the blood draw site with alcohol, and then drawing blood. This process requires repeated procedures by medical staff, is labor-intensive, and inefficient. Therefore, a blood sampling device for medical hematology departments is proposed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blood sampling device for medical hematology departments.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A blood sampling device for use in a medical hematology department includes a U-shaped plate with a base plate at its bottom. A sealing plate is fixedly installed on one side of the top of the U-shaped plate, and an L-shaped plate is fixedly installed on one side of the top of the sealing plate. A U-shaped rod is fixedly installed on the other side of the U-shaped plate, and a mounting sleeve is fixedly fitted around the center of the circumference of the U-shaped rod.

Multiple pneumatic rods are fixedly installed on one side of the top of the base plate. Springs are fixedly installed on both sides of the bottom of the L-shaped plate, and a limit frame is fixedly installed between the top of the pneumatic rod and the bottom of the spring. An airbag is fixedly installed inside the limit frame. An air pump is provided at the top of the sealing plate, and a delivery tube is fixedly connected between the center of the top of the airbag and the air pump.

[0005] Preferably, a first adapter seat is fixedly installed at both ends of one side of the bottom of the U-shaped plate and at both ends of the other side of the top of the base plate, and a hydraulic rod is rotatably installed between the two sets of two first adapter seats. A support column is fixedly installed on the other side of the top of the base plate, and a second adapter seat is fixedly installed in the middle of the other side of the bottom of the U-shaped plate, and the second adapter seat and the support column are rotatably connected.

[0006] Preferably, triangular plates are fixedly installed at the connection points between the two ends of the top of the sealing plate and the two ends of the L-shaped plate, and an indicator sign is fixedly installed at the top of the L-shaped plate.

[0007] Preferably, multiple shock-absorbing columns are fixedly installed between the top of the sealing plate and the bottom of the air pump.

[0008] Preferably, the four corners of the limiting frame are rounded, and the airbag has a rectangular opening in the middle.

[0009] Preferably, a red and green indicator light is fixedly installed on the other side of the top of the base plate.

[0010] Preferably, a third adapter is fixedly installed at the top center of the limiting frame, and a support rod is rotatably installed inside the third adapter. An arc-shaped opening is provided at the middle of the end of the support rod, and a silicone roller is rotatably installed inside the arc-shaped opening. The diameter of the silicone roller is smaller than the diameter of the arc-shaped opening.

[0011] The beneficial effects of this invention are as follows: 1. This invention proposes a blood sampling device for medical hematology departments. Patients prepare by following the instructions on the signage, passing their bare arm through the limiting frame and airbag to the other side of the U-shaped plate, and pressing their palm against the rubber sleeve so that the pressure sensor detects slight pressure. Then, the air pump inflates the airbag, forcefully lifting the upper wall of the patient's arm. The patient then grips the rubber sleeve tightly, exposing the blood vessels in the arm, until the pressure sensor detects the target pressure, turning the red-green indicator light green. Medical staff then perform disinfection and blood sampling. Patients can follow the instructions on the signage to complete the initial steps themselves, while medical staff only need to perform the crucial disinfection and blood sampling, significantly reducing their workload and improving efficiency.

[0012] 2. The present invention proposes a blood sampling device for medical hematology departments, wherein first adapter seats are fixedly installed at both ends of one side of the bottom of a U-shaped plate and at both ends of the other side of the top of the bottom plate, and a hydraulic rod is rotatably installed between the two sets of two first adapter seats.
