Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-coagulation device for blood collection. Background Art

[0002] When blood is collected for inspection, in order to prevent blood clotting, blood collection tubes containing anticoagulants are usually used. In order to fully mix the blood and the anticoagulant or maintain the fluidity of the blood, the blood collection tubes are usually placed in an anti-coagulation device before the blood is collected and sent for inspection. The motor in the blood anti-coagulation device drives the pull rod to rotate, thereby pushing the placement rack to slide back and forth along the width or height direction of the device body under the placement rack to achieve the above purpose.

[0003] However, when the existing blood anti-coagulation device uses a method of pushing the placement rack to move to shake and mix or maintain blood fluidity, the bottom of the container used to install the placement rack not only needs to have space for installing the shaking mechanism, but also needs to have movement space for the placement rack above or on the side, which makes the existing blood anti-coagulation device larger in size and inconvenient to use when collecting blood from specific people outside. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an anti-coagulation device for blood collection, so as to solve the technical problem that the blood anti-coagulation device in the prior art is large in size and inconvenient to use when collecting blood from specific people outside.

[0005] The utility model is realized by the following technical solutions:

[0006] A blood collection anti-coagulation device comprises a device body and a placement rack for placing blood collection tubes, wherein a plurality of supports with elastic support components are fixedly arranged on the bottom wall of the device body;

[0007] The action end of the elastic support component is connected with an impact head, and the impact head is pressed against the bottom of the placement rack under the action of the elastic support component, and the device body is provided with an extrusion component for simultaneously extruding a plurality of the impact heads downward.

[0008] Further, the support is generally concave in shape, and the elastic support assembly includes a mounting plate laterally fixedly connected between two opposite side walls of the support;

[0009] A mounting rod is vertically slidably inserted on the mounting plate, a distance is provided between the lower end of the mounting rod and the concave bottom wall of the support, the upper end of the mounting rod is detachably connected to the impact head, and an elastic member is installed between the impact head and the mounting plate.

[0010] Furthermore, a limit block for limiting the rising distance of the mounting rod is integrally formed at the bottom of the mounting rod; a connecting sleeve is fixedly connected to the impact head, and the upper end of the mounting rod extends into the connecting sleeve and is threadedly connected to the connecting sleeve.

[0011] Furthermore, the extrusion assembly includes a plurality of extrusion members installed on the same horizontal plane, and the plurality of extrusion members are connected as a whole through a connecting rod; a driving component is provided on the device body for driving the plurality of extrusion members to reciprocate simultaneously to extrude the plurality of impact heads.

[0012] Further, the extrusion piece includes an extrusion portion, the extrusion portion has an inclined surface, and the inclined surface faces the impact head;

[0013] It also includes connecting parts integrally formed at both ends of the extrusion part, and the connecting parts are used to connect with the connecting rod and the driving component.

[0014] Furthermore, the driving component includes a sliding rod and a screw rod which are rotatably connected to the device body in a transverse direction, the sliding rod is slidably connected to one of the connecting parts, and the screw rod is threadedly connected to the other connecting part;

[0015] A power source is fixedly connected to the inside of the device body, and gears are respectively installed on the output end of the power source and the screw rod, and the two gears are meshed with each other.

[0016] Furthermore, the device body includes a box body, a box cover hinged to the top of the box body, and a bottom box detachably connected to the bottom of the box body.

[0017] Furthermore, an annular connecting groove is provided on the bottom end surface of the box body, and an annular connecting ring is fixedly connected to the top end surface of the bottom box, and the connecting ring can be plugged and matched with the connecting groove;

[0018] The side of the box body is connected with fixing bolts for fixing the connecting ring to the box body.

[0019] Furthermore, the placement rack includes a frame body fixedly connected to the box body and a placement base, the placement base is located below the frame body, and the shapes of the frame body and the placement base are adapted to the internal space of the box body.

[0020] The beneficial effects of the utility model are:

[0021] 1. By arranging a plurality of impact mechanisms at the bottom of the placement rack, the extrusion assembly can extrude a plurality of the impact heads simultaneously when moving. When the extrusion assembly passes through the impact head at a certain speed, the impact head is quickly reset under the action of the elastic support assembly to slightly impact multiple locations of the bottom of the placement rack at the same time to generate vibration, thereby achieving the effect of fully mixing the blood and the anticoagulant or maintaining the fluidity of the blood.

[0022] 2. Compared with the prior art method of driving the blood collection tube placement rack to move and shake, the utility model generates vibrations through impact to promote the full mixing of blood and anticoagulant or maintain the fluidity of blood. There is no need to reserve moving space in the container for installing the placement rack, so that the structure of the utility model is more compact and small, easy to carry, and is particularly suitable for blood collection and examination of patients outside, such as community medical services, infectious disease prevention and control or other emergency situations.

[0023] 3. The vertical movement generated by the up and down impact of the utility model can directly act on the bottom of the placement rack, which can more effectively disturb the platelets and fibrin in the blood to prevent aggregation and clot formation, and the vertical movement can better penetrate the liquid layer to ensure that the entire blood is evenly mixed;

[0024] Secondly, compared with shaking, up and down bumping produces fewer bubbles, which is particularly important in experimental or medical applications where bubble interference needs to be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] An annular connecting groove 14 is provided on the bottom end surface of the box body 11, and an annular connecting ring 15 is fixedly connected to the top end surface of the bottom box 13, through which the connecting ring 15 can be plugged and matched with the connecting groove 14, and then a fixing bolt 16 for fixing the connecting ring 15 and the box body 11 is connected to the side of the box body 11, so that the bottom box 13 is installed under the box body 11 in a detachable connection manner, which is conducive to disassembly of the bottom box 13 and maintenance of the collision mechanism in the bottom box 13;

[0037] The apparatus further comprises a placement rack 2 for placing blood collection tubes, the placement rack 2 comprising a frame body 21 fixedly connected to the box body 11 and a placement base 22, the placement base 22 being located below the frame body 21, and the shapes of the frame body 21 and the placement base 22 being adapted to the internal space of the box body 11, and the frame body 21 and the placement base 22 are both close to the outlets at both ends of the box body 11, thereby effectively utilizing the internal space of the box body 11;

[0038] Secondly, when the box cover 12 is closed, the inner top wall of the box cover 12 is preferably in contact with the top of the blood collection tube, so as to prevent the blood collection tube from shaking up and down when placed in the placement rack 2, thereby affecting the carrying experience.

[0039] See also Figure 2 and Figure 4 A plurality of supports 3 with elastic support components 4 are fixedly arranged on the bottom wall inside the bottom box 13. The supports 3 described in the present application document are generally concave, and may also be "L"-shaped or other shapes. The action end of the elastic support component 4 is connected to a collision head 5, and the collision head 5 is made of plastic material. The collision head 5 described in the present application document is in the shape of a round cake, and may also be in the shape of a ball or other shapes. The collision head 5 is against the bottom of the placement rack 2 under the action of the elastic support component 4;

[0040] The elastic support assembly 4 includes a mounting plate 41 which is laterally fixedly connected between the two opposite side walls of the support 3 by bolts, and a mounting rod 42 is vertically slidably inserted on the mounting plate 41. There is a gap between the lower end of the mounting rod 42 and the concave bottom wall of the support 3, leaving a movable space for the downward movement of the mounting rod 42. The upper end of the mounting rod 42 is detachably connected to the impact head 5, and an elastic member 43 is installed between the impact head 5 and the mounting plate 41. The elastic member 43 described in the present application document is a spring, and the elastic member 43 is sleeved outside the mounting rod 42;

[0041] A limit block 44 for limiting the rising distance of the mounting rod 42 is integrally formed at the bottom of the mounting rod 42; a connecting sleeve 45 is fixedly connected to the impact head 5, and the upper end of the mounting rod 42 extends into the connecting sleeve 45 and is threadedly connected to the connecting sleeve 45.

[0042] See also Figure 2 and Figure 5The bottom box 13 is provided with an extrusion assembly 6 for simultaneously extruding a plurality of the impact heads 5 downward to move downward, the extrusion assembly 6 includes a plurality of extrusion members 61 installed on the same horizontal plane, the extrusion members 61 are in the shape of a thin plate as a whole, and the plurality of the extrusion members 61 are connected as a whole by a connecting rod 62; the bottom box 13 is provided with a driving component 63 for driving the plurality of the extrusion members 61 to simultaneously reciprocate and extrude the plurality of the impact heads 5;

[0043] The extrusion member 61 includes an extrusion portion 611, the extrusion portion 611 has an inclined surface 612, the slope of the inclined surface 612 is relatively large, the inclined surface 612 faces the impact head 5, the cross section of the extrusion portion 611 is an isosceles trapezoid, and the extrusion member 61 also includes connecting portions 613 integrally formed at both ends of the extrusion portion 611, and the connecting portions 613 are used to connect with the connecting rod 62 and the driving component 63;

[0044] The driving component 63 includes a sliding rod 631 and a screw rod 632 which are laterally rotatably connected to the device body 1. The sliding rod 631 is slidably connected to one of the connecting parts 613, and the screw rod 632 is threadedly connected to the other connecting part 613. A power source 633 is fixedly connected to the bottom wall of the bottom box 13. The power source 633 adopts a servo motor. Gears 634 are respectively installed on the output end of the power source 633 and the screw rod 632, and the two gears 634 are meshed with each other. The gear 634 adopts a bevel gear 634.

[0045] The working principle of the utility model is as follows: the power source 633 is used to intermittently drive the screw 632 to rotate forward and reversely, and the screw 632 can drive the extrusion member 61 to move back and forth along the length direction of the screw 632 when the screw 632 rotates forward and reverse intermittently. The slide bar 631 is used to assist the movement of the extrusion member 61. When the extrusion member 61 moves close to the impact head 5, the inclined surface 612 of the extrusion member 61 first contacts the arc surface of the impact head 5, and the inclined surface 612 is conducive to the extrusion member 61 to continue to move and squeeze the impact head 5 to move downward. At this time, the mounting rod 42 slides downward under the action of the impact head 5, and the impact head 5 compresses the elastic member 43. When the extrusion member 61 moves so that the extrusion portion 611 completely passes through the impact head 5 at a certain speed, the impact head 5 quickly and slightly impacts the bottom of the placement base 22 under the force generated by the elastic member 43 deforming back to its original state. After completing one impact, the power source 633 drives the screw 632 to rotate in the opposite direction, so as to drive the extrusion member 61 to move back and forth to perform multiple impacts.

[0046] By arranging a plurality of impact mechanisms under the placement rack 2, and connecting a plurality of the extrusion members 61 as a whole through the connecting rod 62, each of the extrusion members 61 is at the same distance from the impact head 5 in its moving direction, and when the extrusion members 61 move, they can respectively and simultaneously squeeze the plurality of impact heads 5, thereby driving the plurality of impact heads 5 to slightly impact multiple locations on the bottom of the placement rack 2 at the same time, so as to generate vibration to fully mix the blood with the anticoagulant or maintain the fluidity of the blood;

[0047] The start time of the power source 633 can be set by the controller, so that the vibration time and interval can be controlled to ensure that the processing conditions of all blood collection tubes are consistent. In addition, an insulation layer or a temperature control system can be set on the inner wall of the box 11 as needed to ensure that the collected blood is stored at a suitable temperature to avoid blood deterioration due to temperature fluctuations, thereby ensuring blood quality.

[0048] Finally, it should be noted that the above-mentioned implementation is only a preferred implementation of the utility model, and cannot be used to limit the scope of protection of the utility model. Any non-substantial changes and substitutions made by technicians in this field on the basis of the utility model are within the scope of protection required by the utility model.
