Make the placing plate slide down, and then push the connecting plate through the push plate, so that the connecting plate pushes the push rod to move to the right, so that the connecting ring pushes the connecting rod to move, so that the transmission gear rotates, and the rotation of the transmission gear drives the rotation gear to rotate, so that The test tube placed on the test tube tray is rotated to a position perpendicular to the middle of the placing plate, and then the blood collection can be carried out by binding the strapping tape. After the blood collection is completed, the personnel arm is lifted to make the placing plate reset under the action of the return spring, and then The next test tube is rotated by half, which realizes the automatic replacement of the test tube, and prevents the blood collected in the test tube from coagulating when the person does not shake it, which brings convenience to the use of the personnel.

Description

A blood sample collection device for outpatient clinic

technical field

The utility model relates to the technical field of blood collection, in particular to a blood sample collection device used in outpatient clinics.

Background technique

Blood collection refers to the process of taking blood samples by medical personnel through veins and arteries for inspection or related needs. Blood collection is undertaken by medical staff and personnel who have been specially trained in blood collection technology, and they are not allowed to work without special training; the proficiency of blood collection technology is directly related to the quality of blood and the health of blood donors, so it is required that each blood collection personnel must be proficient in Blood collection technique. Proofread the electronic blood collection instrument (blood collection measuring scale), check the quality of the blood collection bag again (whether there is rupture, water leakage, mildew, the amount of stored liquid, etc.), and check that the blood donor and the full set of cards are consistent with the blood collection bag and tube sign. Lay the donor's arm flat and attach a tourniquet or blood pressure monitor approximately 5 cm above the cubital fossa. Choose the median cubital vein that is thick, full, elastic, and not easy to slide, followed by the expensive vein; because the cephalic vein is easy to slide, it is only selected when the former is difficult to reach. Sterilize the venipuncture point and surrounding skin with 2.5% iodine tincture, with a range of about 8 to 10 cm. After the iodine tincture is dry, deiodine with 75% ethanol. Place the blood collection bag on the forearm of the blood donor, clamp the blood collection catheter with hemostatic forceps, remove the needle protection cap of the blood collection needle, puncture, and release the hemostatic forceps when blood returns; cover the eye of the needle with a sterile cotton ball and fix it with tape.

At present, when blood samples are collected in outpatient clinics, it is necessary to repeatedly take test tubes for blood collection, which will seriously affect the efficiency of blood collection, and it is necessary to shake after the blood collection is completed to prevent the internal blood from coagulating. In the case of blood coagulation, we propose a blood sample collection device for outpatient clinics to solve the above problems.
