Description

Technical Field

[0001] The utility model relates to the technical field of placing racks, in particular to a vacuum blood collection tube placing rack. Background Technique

[0002] A vacuum blood collection tube is a disposable negative pressure vacuum glass tube that can achieve quantitative blood collection and needs to be used in conjunction with a venous blood collection needle. The principle of the vacuum blood collection tube is to pre-pump the blood collection tube with a head cover to different vacuum degrees, and use its negative pressure to automatically quantitatively collect venous blood samples. One end of the blood collection needle is inserted into the human vein and the other end is inserted into the rubber stopper of the vacuum blood collection tube. The human venous blood is inside the vacuum blood collection tube and is drawn into the blood sample container through the blood collection needle under the action of negative pressure. Under one venous puncture, multiple tubes can be collected without leakage. The inner cavity volume of the connecting blood collection needle is very small, and the influence on the blood collection volume can be ignored.

[0003] When a large number of vacuum blood collection tubes are used, they will be placed in cooperation with a placing rack. The vacuum blood collection tubes are placed in the placing holes of the placing rack to achieve placing and positioning, so that the vacuum blood collection tubes can be placed neatly and tightly. However, when the existing placing rack is in use, when there are many vacuum blood collection tubes, using two placing racks will occupy a large area of the workbench, and stacking the placing racks will cause the lower placing rack to be blocked, resulting in inconvenient access. Therefore, a vacuum blood collection tube placing rack is proposed to improve the above situation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vacuum blood collection tube placing rack to solve the problems raised in the above background technique.

The second gear 6 and the third gear 7 are fixedly connected with the connecting shaft. A clip holder 9 adapted to it is arranged in the tray 8. Positioning holes 10 are evenly opened on the bottom surface of the clip holder 9. The positioning holes 10 can form a positioning and supporting effect on the bottom of the vacuum blood collection tube 12. Limiting holes 11 are evenly opened on the top surface of the clip holder 9. The diameter of the limiting holes 11 is adapted to the outer diameter of the vacuum blood collection tube 12. The vacuum blood collection tube 12 with a label pasted on it can be conveniently inserted into the limiting holes 11 and is supported on the side through the limiting holes 11, so that the vacuum blood collection tube 12 is vertically and stably placed. The vacuum blood collection tube 12 is jointly arranged in the limiting holes 11 and the positioning holes 10.

[0022] The clip holder 9 cooperates with the limiting holes 11 and the positioning holes 10 to place and store the vacuum blood collection tube 12. The clip holder 9 is placed through the tray 8 to form an upper and lower double-layer placement. During the rotation of the rotating arm 5, the second gear 6 rolls on the first gear 4, thereby forming a rotation. The rotating second gear 6 drives the third gear 7 to rotate. The third gear 7 drives the tray 8 to rotate synchronously, so that the tray 8 can be kept horizontal, forming the up and down switching of the clip holder 9. The double-layer storage placement can place more vacuum blood collection tubes 12. At the same time, the clip holder 9 can be conveniently switched up and down, so as to facilitate the taking and placing of the vacuum blood collection tube 12.

[0023] Please refer to Figure 3, mounting holes are provided at the four corners of the clip holder 9, and threaded posts 13 are fixedly connected to the tray 8 corresponding to the mounting holes. The top end of the threaded post 13 passes through the mounting hole and is threadedly connected to a hand-tightening nut 14.

[0024] The clip holder 9 is fixed in the tray 8 by the cooperation of the threaded post 13 and the hand-tightening nut 14, so that the clip holder 9 is more stable and the situation of falling off is avoided.

[0025] Please refer to Figure 4 , four positioning grooves 15 are circumferentially provided at the position of the rotating arm 5 corresponding to the first gear 4, and the positioning grooves 15 are quarter-spherical grooves.

[0026] A hand-tightening bolt 16 is threadedly connected to the vertical plate 2 corresponding to the positioning groove 15. The hand-tightening bolt 16 passes through the first gear 4. A hexagonal nut for threaded connection of the hand-tightening bolt 16 is fixedly connected to the vertical plate 2. Through holes for the hand-tightening bolt 16 to pass through are provided on both the vertical plate 2 and the first gear 4. The end of the hand-tightening bolt 16 is provided with a first hemispherical head 17 adapted to the positioning groove 15, and the first hemispherical head 17 can be inserted into the groove 15.

[0027] A contraction groove 18 is fixedly connected to the upper part of the first gear 4 corresponding to the positioning groove 15. A top block 19 adapted to it is slidably connected in the contraction groove 18. A spring 20 is provided between the top block 19 and the bottom of the contraction groove 18. A second hemispherical head 21 adapted to the positioning groove 15 is fixedly connected to the side of the top block 19 corresponding to the positioning groove 15, and the second hemispherical head 12 can be inserted into the groove 15.

[0028] Through the setting of the positioning groove 15, during the rotation of the rotating arm 5, the spring 20 presses the top block 19, so that the second hemispherical head 21 is always pressed against the positioning groove 15, thereby forming a rotation jamming, which is convenient to control the rotating arm 5 to rotate to 90° and 180°, and cooperate with the rotation of the hand-tightening bolt 16, so as to control the first hemispherical head 17 to be inserted into the positioning groove 15 to form a fixing effect, and avoid the instability of the tray 8 after the handle 15 rotates and switches.

[0029] The working principle of the present utility model is:

[0030] During use, place the placement rack on the tabletop through the base 1, and place the paper clip rack 9 in the tray 8. At this time, the threaded column 13 passes through the paper clip rack 9 through the mounting hole. Then, screw the hand-tightening nut 14 onto the threaded column 13 to lock the paper clip rack 9. At this time, the vacuum blood collection tube 12 can be inserted into the corresponding limit hole 11. After the paper clip rack 9 is full, rotate the hand-tightening bolt 16 to make the first hemispherical head 17 leave the positioning groove 15, and rotate the rotating arm 5 so that the upper and lower rings of the rotating arm 5 are formed. During the rotation of the rotating arm 5, the second gear 6 rolls on the first gear 4, thus forming a rotation. The rotating second gear 6 drives the third gear 7 to rotate, and the third gear 7 drives the tray 8 to rotate synchronously, so as to keep the tray 8 horizontal and form the up and down switching of the paper clip rack 9. During the rotation, the second hemispherical head 21 is squeezed against the edge of the positioning groove 15, so that the top block 19 compresses the spring 20 to form a contraction. Every time the rotating arm 5 rotates 90°, the second hemispherical head 21 is ejected into the positioning groove 15 by the spring 20 to form a jamming positioning. Then, rotate the hand-tightening bolt 16 to make the first hemispherical head 17 at the end of the hand-tightening bolt 16 insert into the positioning groove 15, so as to form a fixing effect. At this time, the vacuum blood collection tube 12 can be continuously placed on the blank paper clip rack 9 for double-layer placement, with a larger capacity.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
