Description

Technical Field

[0001] The invention belongs to the technical field of medical blood sampling, and in particular relates to an automatic peripheral blood sampling device. Background Art

[0002] Peripheral blood sampling is a common method for collecting blood specimens and an effective supplement to venous blood collection. It punctures the capillaries on the surface of the ring finger instead of venous blood to facilitate relevant medical examinations. It is usually used to quickly detect and monitor certain components in the blood, such as blood sugar, blood lipids, hemoglobin, etc. This method is widely used in clinical and home care, and is particularly suitable for blood sugar monitoring in diabetic patients.

[0003] Steps for peripheral blood sampling

[0004] Preparation: Equipment: Prepare a blood collection device (such as a fingertip blood collection needle), alcohol cotton balls, cotton balls or gauze, and appropriate blood collection tubes. Disinfection: Use an alcohol cotton ball to disinfect the blood collection site (usually one side of the finger) and let it air dry naturally. Blood collection: Piercing: Use the needle of the blood collection device to pierce the side of the fingertip, usually the ring finger or middle finger. The piercing depth should be moderate to avoid discomfort or injury caused by excessive depth. Squeezing: Gently squeeze the fingertip to make the blood flow out. Avoid excessive force to prevent blood from mixing with tissue fluid. Collection: Use a test tube or other container to collect blood samples. Hemostasis and cleaning: After blood collection, gently press the piercing point with a cotton ball or gauze until the bleeding stops. After processing, dispose of the used blood collection equipment safely to avoid cross infection. Sample processing: If immediate analysis is required, send the sample to the laboratory for testing as soon as possible; if it is a home monitoring device, just follow the instructions.

[0005] The peripheral blood sampling method is convenient and fast, and is suitable for a variety of testing purposes, such as: Diabetes management: regular monitoring of blood sugar levels to help patients adjust their diet and medications, Screening and diagnosis: used to quickly screen certain components in the blood to facilitate timely diagnosis, Blood monitoring: monitor the health status of patients in a medical environment. Although peripheral blood sampling is simple, it is still necessary to follow relevant operating specifications to ensure the accuracy and safety of the sample.

[0006] The prior art discloses some invention patents in the field of medical blood collection technology, among which the invention patent with application number CN202011488532.6 discloses a peripheral blood sampling device, which squeezes and fixes the limb to be blooded by setting an extrusion body in the fixing device, and movably connects the blood sampling device with the base so that the blood sampling device can be moved to an opening of the fixing device to collect blood from the limb to be blooded, thereby realizing automated blood collection of the peripheral blood sampling device, thereby reducing the cost of manual blood collection, improving the speed and efficiency of the blood collection process, and realizing the standardization of the blood collection process, so as to further improve the efficiency and accuracy of blood collection and improve the blood collection pass rate.

[0007] When the existing technology is used, if the patient is a child who is young and has poor compliance, peripheral blood collection has high technical requirements for the operator, and it is necessary to control the puncture depth, force and angle. The built-in needle of the contact pressure blood collection device can quickly complete a pop-up and retraction, but the puncture depth of the existing technology is constant, and it is not easy to draw blood for patients with rough skin.

One side of the unwinding roller 704 and the taking-up roller 705 are slidably contacted with the limiting cover 601. The motor B703 drives the transmission shaft B702 to rotate, so that the transmission shaft B702 drives the taking-up roller 705 to rotate, so that the taking-up roller 705 can drive the plastic belt 706 to reel up, and at this time, the cotton pad 707 soaked in alcohol will be driven to move, so that the cotton pad 707 can contact the outer wall of the tactile sensor 407 to disinfect it.

[0056] Specifically, Fig. 9 , Fig.10As shown, an addition tube 801 is fixedly connected through the alcohol seat 8, a sealing plug 802 is threadedly connected on the addition tube 801, a liquid pressing plate 803 is slidably provided in the alcohol seat 8, a threaded rod 804 is rotatably connected through the alcohol seat 8, the threaded rod 804 is threadedly connected to the liquid pressing plate 803, a universal joint 805 is fixedly connected to the outer end of the threaded rod 804, the other end of the universal joint 805 is rotatably connected to the bottom end of the alcohol seat 8, a toothed wheel 806 is fixedly connected to the universal joint 805, a pin is rotatably connected through one side of the toothed wheel 806, a transmission wheel 807 is fixedly connected to the outer end of the pin, the transmission wheel 807 is meshed with the transmission rack 302 for transmission, one end of the pin located in the toothed wheel 806 is fixedly connected to a toothed disc 808, a plurality of meshing teeth 809 are rotatably provided in the toothed disc 808 in an annular structure, and one end of the meshing teeth 809 is connected A tension spring 810 is fixedly arranged, and the other end of the tension spring 810 is connected and fixed to the inner wall of the toothed disc 808. The meshing teeth 809 are meshed with the toothed wheel 806 for transmission. The liquid outlet end of the alcohol seat 8 is located above the plastic belt 706. When the skin roughness detection mechanism 4 rotates to the upper side, the transmission rack 302 on the rotating frame 3 will drive the transmission wheel 807 to rotate, so that the transmission wheel 807 can drive the toothed disc 808 to rotate. At this time, the meshing teeth 809 on the toothed disc 808 are under the action of the tension spring 810, so that when the toothed disc 808 rotates in the opposite direction, the meshing teeth 809 will not mesh with the toothed wheel 806. When the toothed disc 808 rotates, the universal joint 805 connected to the toothed wheel 806 can be driven to rotate, so that the universal joint 805 drives the threaded rod 804 to rotate, and the threaded rod 804 drives the threaded rod 804 to move downward, squeezing the alcohol in the alcohol seat 8 and dripping it onto the cotton pad 707 on the plastic belt 706.

[0057] Working principle, when in use: first place the finger to be blood drawn on the finger rack 201, then constrain the finger under the action of the elastic band 202, and then use the motor A301 to drive the rotating rack 3 to rotate, so that the skin roughness detection mechanism 4 rotates to the lower side, at this time, under the action of the adjustment rack 203, the worm 401 connected to the adjusting wheel 402 will rotate, so that the worm 401 drives the connecting rod group 404 connected to the worm wheel 403 to rotate, so that the other end of the connecting rod group 404 drives the adjusting seat 405 to move downward, so that the tactile sensor 407 can be pressed on the finger to be blood drawn. At this time, when the tactile sensor 407 contacts the skin surface, it will measure the changes in physical quantities such as pressure, displacement or capacitance. By measuring the changes in capacitance, it can sense the slight changes in the contact surface. The rough surface will affect the capacitance value of the tactile sensor 407, so that the roughness of the finger skin surface can be inferred;

[0058] Then the rotating frame 3 rotates in the opposite direction, so that the puncture mechanism 5 rotates to the lower side, so that the electric push rod 501 drives the disposable blood collection needle 503 on the needle holder 502 according to the measured roughness to accurately control the puncture depth of the blood collection needle;

[0059] When the skin roughness detection mechanism 4 rotates to the upper side, the transmission rack 302 on the rotating frame 3 drives the transmission wheel 807 to rotate, so that the transmission wheel 807 can drive the toothed disc 808 to rotate. At this time, the meshing teeth 809 on the toothed disc 808, under the action of the tension spring 810, when the toothed disc 808 rotates in the opposite direction, the meshing teeth 809 will not mesh with the toothed wheel 806. When the toothed disc 808 rotates, the universal joint 805 connected to the toothed wheel 806 can be driven to rotate, so that the universal joint 805 drives the threaded rod 804 to rotate, so that the threaded rod 804 drives the threaded rod 804 to move downward, squeezing the alcohol in the alcohol seat 8 and dripping it onto the cotton pad 707 on the plastic belt 706;

[0060] Then, the motor B703 is used to drive the transmission shaft B702 to rotate, so that the transmission shaft B702 drives the take-up roller 705 to rotate, so that the take-up roller 705 can drive the plastic belt 706 to reel up, and at this time, the cotton pad 707 soaked with alcohol will be driven to move, so that the cotton pad 707 can contact the outer wall of the tactile sensor 407 to disinfect it;

[0061] After the cotton pad 707 is used up and needs to be replaced, open the limiting cover 601, then remove the unwinding roller 704 and the taking-up roller 705 from the transmission shaft A701 and the transmission shaft B702, insert the new unwinding roller 704 and the taking-up roller 705 onto the transmission shaft A701 and the transmission shaft B702 respectively, and then pull out the plastic belt 706 to wrap around the two guide rollers 603 for use.
