TECHNICAL FIELD
[0001] The utility model belongs to blood test device technical field, concretely relates to a kind of anticoagulated blood specimen clot identification filter. BACKGROUND
[0002] Hospital for patient blood specimen collection, due to various reasons will lead to blood specimen tube coagulation forms clot. If nurse in collection blood, not in time with anticoagulant fully mixed blood, or mixed uniform way is incorrect;Blood volume is too much or too little, affect the proportion of anticoagulant and blood;Anticoagulant is not enough or anticoagulant in the process of transportation appears improper situation, such as adsorbed on rubber plug, can lead to anticoagulant relative to those actually collected blood volume is insufficient. Certain patient's blood is in hypercoagulable state, especially the patient with certain malignant tumor, hyperlipidemia or blood viscosity high patient etc.
[0003] In addition, blood specimen is in temperature lower environment after collection, especially room temperature is lower than standard condition, blood in blood coagulation factor can cause blood spontaneous coagulation. These clots are usually small in size, it is difficult to distinguish with naked eye, especially EDTA-K2 anticoagulant tube and sodium citrate anticoagulant tube detects blood routine and coagulation detection when blood clot in blood has very big influence on test result, laboratory staff suspect that the result abnormality caused by blood clot in blood, can not judge with naked eye whether there is clot, can only notify patient to rebleed review, and a part of patient can exist repeated blood drawing problem. Patient causes certain harm and loss, give clinical medical staff also caused certain work burden. UTILITARIAN CONTENT
[0004] The utility model provides a kind of anticoagulated blood specimen clot identification filter, to reduce the test result error caused by blood clot, reduce patient repeated blood drawing and the work burden of clinical medical staff, improve work efficiency.
[0005] Therefore, the utility model adopts following technical scheme:
[0006] A kind of anticoagulated blood specimen clot identification filter, including support, glass test tube, blood collection tube and two-way opening sleeve tube;
[0007] The blood collection tube stores the blood collected, and the filtered blood in the blood collection tube is stored in the glass test tube;The glass test tube and the blood collection tube are oppositely opened, and the blood collection tube is higher than the glass test tube;
[0008] The inner cavity center of the two-way opening sleeve is provided with a filter membrane, the outer edge of the filter membrane is in sealing connection with the inner wall of the two-way opening sleeve, the inner diameter of the two-way opening sleeve is equal to the outer diameter of the glass test tube and the blood collection tube; the two ends of the two-way opening sleeve are connected with the glass test tube and the blood collection tube respectively, and the tube openings of the glass test tube and the blood collection tube abut against the filter membrane.
[0009] The glass test tube and the blood collection tube are placed on the support.
[0010] Further, the inner diameter and the outer diameter of the glass test tube and the blood collection tube are equal.
[0011] Further, one side of the support is provided with a slope, the glass test tube and the blood collection tube are fixed on the slope, the blood collection tube is on the upper side and the glass test tube is on the lower side.
[0012] Further, the bottom of the slope of the support is fixed with a horizontal block, a plurality of grooves are formed on the slope surface and are perpendicular to the horizontal block; the glass test tube and the blood collection tube are placed in the grooves of the slope and the glass test tube abuts against the horizontal block.
[0013] The blood collection tube is placed on the slope of the support upward, and the blood in the blood collection tube is detected for 10 minutes, and then the blood in the blood collection tube enters the lower glass test tube through the filter membrane, and the blood clot in the blood is left on the filter membrane, so that whether the blood clot exists in the blood can be directly observed. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 is a structural schematic view of the utility model;
[0015] Figure 2 is a schematic view of the support of the utility model;
[0016] In the drawing: glass test tube-1, two-way opening sleeve-2, filter membrane-3, blood collection tube-4, support-5, 6-block, 7-groove. DETAILED DESCRIPTION
[0017] The utility model will be further described in combination with the drawings and specific embodiments:
[0018] As Figure 1As shown, an anticoagulated blood sample clot identification filter includes a support 5, a glass test tube 1, a blood collection tube 4, and a bidirectional open sleeve 2. The inner and outer diameters of the glass test tube 1 and the blood collection tube 4 are equal. The blood collection tube 4 holds the collected blood, and the blood in the blood collection tube 4 is filtered and then stored in the glass test tube 1. The openings of the glass test tube 1 and the blood collection tube 4 are opposite each other, and the blood collection tube 4 is positioned higher than the glass test tube 1. A filter membrane 3 is provided at the center of the inner cavity of the bidirectional open sleeve 2, and the outer edge of the filter membrane 3 is sealed to the inner wall of the bidirectional open sleeve 2. The inner diameter of the bidirectional open sleeve 2 is equal to the outer diameter of the glass test tube 1 and the blood collection tube 4. The two ends of the bidirectional open sleeve 2 are respectively connected to the glass test tube 1 and the blood collection tube 4, and the openings of the glass test tube 1 and the blood collection tube 4 respectively abut against the filter membrane 3. The glass test tube 1 and the blood collection tube 4 are placed on the support 5.
[0019] like Figure 2 As shown, a ramp is provided on one side of the support 5. The glass test tube 1 and the blood collection tube 4 are fixed on the ramp, with the blood collection tube 4 on top and the glass test tube 1 on the bottom. A horizontal stop 6 is fixed at the bottom of the ramp of the support 5. Multiple grooves 7 are opened on the ramp surface, and the grooves 7 are perpendicular to the horizontal stop 6. The glass test tube 1 and the blood collection tube 4 are placed in the grooves 7 of the ramp, and the glass test tube 1 is against the horizontal stop 6.
[0020] The method of using this utility model is as follows: Before use, remove the cap of the blood collection tube 4 and the dust cover of the bidirectional open sleeve 2. The filter membrane 3 ensures that all blood cells can pass through, but blood cell clots and fibrinogen clots cannot. After connecting the two parts, place the blood collection tube 4 upwards on the slope of the support 5 and let it stand for 10 minutes. The blood in the blood collection tube 4 to be tested will pass through the filter membrane 3 into the lower glass test tube 1. The blood clots will remain on the filter membrane 3, allowing for direct observation of whether there are clots in the blood. If no clots are present, the blood sample will not be re-drawn for retesting. The bidirectional open sleeve 2 is for single use only and will not be reused, fundamentally eliminating sample contamination.
[0021] Practical application example of this utility model: The filter membrane of this utility model uses a cell filter membrane product from BKMAMLAB, with a product specification of 40μm. Initially, 50 sets of samples were purchased. After a two-month trial in our hospital's laboratory department, it received positive feedback from the laboratory staff. It reduced the harm and losses caused by repeated blood draws for some patients, reduced errors in test results due to blood clots, and improved the work efficiency of medical personnel.
