Description
Technical Field
The invention relates to the technical field of test tube supports.
Background
In order to better judge the state of illness of a patient, a hospital generally needs blood sampling and detection on the patient; blood sampling belongs to the work that the hospital will go on every day, need place blood sample on the storage rack after the normal blood sampling to this realizes the concentrated storage of a plurality of blood samples.
At present, in order to increase the number of stored blood samples, the distance between adjacent blood samples is small; the blood specimen is mainly characterized in that blood is introduced into a test tube and then sealed by a sealing cover; however, the diameter of the common sealing cover is larger than that of the test tube, and the heights of the stored blood samples are consistent, so that the distance between two adjacent sealing covers is smaller; when a blood sample is actually taken, medical staff mainly take out the whole blood sample by holding the sealing covers, and the blood sample is very inconvenient to take out due to the small distance between the two adjacent sealing covers; and, the blood sample is only placed on the storage rack, and the blood sample can rock in the storage rack, and is not fine spacing to the blood sample, and medical staff will let the blood sample shift out the storage rack and fall to subaerial slightly carelessly bumping the storage rack, if have other medical staff just through stepping on the blood sample that drops, will directly lead to the blood sample that drops to scrap and can not use.
Disclosure of Invention
The invention aims to provide a specimen placing frame to solve the problem that medical staff are inconvenient to take out of an existing placing frame at present.

The specific implementation process is as follows:
when in use, the blood samples are put into the storage tank 4 one by one; the sealing cover is manually pressed, the sealing cover drives the test tube 26 to move downwards, the test tube 26 presses the first rack 10 to move downwards, the first rack 10 drives the first wedge block 19 to move downwards, the first wedge block 19 presses the second wedge block 20 to enable the second wedge block 20 to move outwards, and the first spring 22 is stretched; the first wedge 19 continues to move downwards, the first wedge 19 presses the second spring 23, so that the two springs compress; when the limiting groove 21 is transversely opposite to the second wedge 20, the second wedge 20 extends leftwards into the limiting groove 21 under the action of the first spring 22, and then the second wedge 20 is limited through the limiting groove 21, namely, the rack is limited, so that the test tube 26 cannot move downwards any more; at this time, the test tube 26 is positioned in the storage tank 4, and the sealing lid is positioned outside the storage tank 4.
During the downward movement of the first rack 10, the first rack 10 drives the first gear 8 to rotate clockwise, the first gear 8 drives the rotating shaft 6 to rotate clockwise, and the torsion spring deforms; the rotating shaft 6 drives the clamping arm to rotate clockwise, so that the clamping arm moves towards the test tube 26; when the rack locking, press from both sides tight arm and paste with test tube 26 mutually, and then realize pressing from both sides tight to test tube 26 through the cooperation of pressing from both sides tight arm and 4 inner walls of hold up tank, realize the location to the blood sample promptly, avoid rocking of blood sample, and then avoid medical staff to collide carelessly slightly and cause the condition that the blood sample shifts out hold up tank 4, guaranteed the safe of blood sample and deposited.
During the downward movement of the first rack 10, the first rack 10 drives the first gear 8 to rotate clockwise, the first gear 8 drives the rotating shaft 6 to rotate clockwise, the rotating shaft 6 drives the circular shaft 13 to rotate clockwise through the belt 14, the circular shaft 13 drives the second gear 15 to rotate clockwise, the second gear 15 drives the second rack 16 to move rightwards, and further drives the transverse block 12 and the triangular block 18 to move rightwards; the diameter of the round shaft 13 is smaller than that of the rotating shaft 6, so that the rotating speed of the round shaft 13 is greater than that of the rotating shaft 6, and the moving speed of the triangular block 18 is greater than that of the clamping arm; because one corner of the triangular block 18 is positioned between the two arc-shaped plates 17 and is abutted against the two arc-shaped plates 17, the triangular block 18 moves rightwards to press the two arc-shaped plates 17 to be unfolded towards two sides, namely, the distance between the two arc-shaped plates 17 is gradually increased; due to the increased distance between the two arc plates 17, the arc inner tube 25 slides in the arc outer tube 24, and the return spring is stretched.
When the rack stops, the two arc-shaped plates 17 are attached to the test tube 26, and the fixing plate 7 is attached to the test tube 26; because the triangular block 18 extrudes the two arc-shaped plates 17 to expand towards two sides, compared with the clamping of one action point on the test tube 26, the number of the action points on the test tube 26 is increased through the two arc-shaped plates 17, and the clamping effect on the test tube 26 is further enhanced; moreover, a triangular structure is formed by connecting the action points of the two arc-shaped plates 17 with the action points of the storage tank 4, so that the stability of clamping the test tube 26 can be improved according to the stability of the triangle.
Because a plurality of hold tanks 4 are along the length direction setting of slope piece 3, consequently, a plurality of hold tanks 4 have the difference in height for have the difference in height after a plurality of blood specimens location, make two adjacent sealed lids have the difference in height, and then make things convenient for medical staff's hand to grip. When a bleeding sample needs to be taken, the second wedge block 20 is pulled to move out of the limiting groove 21, and the first spring 22 is stretched; the limiting effect of the second wedge 20 on the first wedge 19 disappears, and further the limiting effect on the first rack 10 disappears; the rotating shaft 6 rotates anticlockwise under the action of the torsion spring, the rotating shaft 6 drives the round shaft 13 to rotate anticlockwise through the belt 14, the round shaft 13 drives the second gear 15 to rotate anticlockwise, and the second gear 15 drives the second rack 16 to move leftwards; the rotating shaft 6 can also drive the two arc-shaped plates 17 to rotate reversely, so that the clamping effect on the test tube 26 is eliminated.
And, when the limiting action of second voussoir 20 to first voussoir 19 disappears, first voussoir 19 moves up under the effect of second spring 23, and first voussoir 19 drives first rack 10 and moves up, and first rack 10 drives test tube 26 and moves up, and then makes things convenient for medical staff to take out the blood sample.
In this embodiment, a flexible layer is bonded to one side of the arc plate 17 away from the transverse block 12, and the flexible layer is a rubber layer; because the flexible layer is flexible material, replace the direct and test tube 26 contact of arc 17 through the flexible layer, effectively avoid the wearing and tearing to test tube 26.
Example two
