Description

Technical Field

[0001] This utility model relates to the field of blood collection tube technology, specifically to an automatic detachable blood collection tube cap device. Background Technology

[0002] Blood collection tubes are specialized containers used in medical testing to collect blood samples. They come in various types, but the existing blood collection tubes mainly consist of a tube body and a cap. The tube body and cap are connected by a pressing method and fit together tightly, resulting in a high degree of security. When the collected blood sample needs to be removed for analysis, the tube body and cap need to be separated.

[0003] Existing methods for transferring blood samples from blood collection tubes require opening the tube cap, which is often done manually. This is cumbersome, time-consuming, and labor-intensive, and can cause the blood collection tube to shake during disassembly, potentially leading to blood spillage. Therefore, we propose an automatic disassembly device for separating blood collection tube caps. Utility Model Content

[0004] The purpose of this invention is to provide an automatic detachable blood collection tube cap device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic detachable blood collection tube cap device, including a base, a carrier block fixedly installed on the top of the base, a positioning hole opened on the top of the carrier block, and a tube positioning component disposed in the positioning hole;

[0006] A support plate is fixedly installed on one side of the top of the base. A horizontal plate is fixedly installed on the upper side of one side wall of the support plate. A first electric actuator is fixedly installed on the top of the horizontal plate. The actuator rod of the first electric actuator moves through the horizontal plate and is fixedly connected to a lifting plate. A rotating shaft is rotatably installed at the bottom center of the lifting plate. A cover is fixedly connected to the tail end of the rotating shaft. A second clamping plate is provided on both sides of the inner cavity of the cover. A second electric actuator is fixedly installed on both side walls of the cover. The actuator rod of the second electric actuator moves through the cover and is fixedly connected to the corresponding second clamping plate.

[0007] By adopting the above technical solution, the tube body is placed in the positioning hole and positioned using the tube body positioning component. Then, the first electric push rod drives the lifting plate to descend, so that the cover is placed on the tube cap. Then, the second electric push rod is activated to drive the second clamping plates on both sides to move, thereby using the two second clamping plates to hold the tube cap. Then, the first electric push rod drives the lifting plate to rise, thereby realizing the rapid separation of the tube body and the tube cap without manual operation, which is conducive to improving the convenience of operation, saving manpower, and also helps to avoid blood splattering due to tube shaking.

[0008] In a preferred embodiment of this utility model, a second gear is fixedly mounted on the outer wall of the rotating shaft, and a first gear meshes with the outer wall of the second gear. The first gear is fixed to the outer end of the transmission shaft of the servo motor, and the servo motor is fixedly installed on the lower side of the lifting plate.

[0009] By adopting the above technical solution, the servo motor can drive the first gear to rotate, which in turn drives the second gear to rotate, thereby driving the rotating shaft to rotate. When the tube cap is pulled upward, the cover causes the tube cap to rotate, which helps to improve the effect of separating the tube cap and the tube body and improves the separation efficiency.

[0010] In a preferred embodiment of this utility model, the tube positioning assembly includes a first clamping plate, which is disposed on both sides of the positioning hole cavity. A sliding cavity is provided on the top of the base. A dual-axis motor is fixedly installed in the middle of the inner cavity of the sliding cavity. Both ends of the dual-axis motor are fixedly connected to lead screws. The outer end of the lead screw is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The top of the lead screw slider is fixedly connected to the corresponding first clamping plate.

[0011] By adopting the above technical solution, the dual-axis motor drives the lead screws on both sides to rotate, thereby driving the lead screw sliders on both sides to move, so that the first clamping plates on both sides clamp the tube body, thereby achieving tube body positioning.

[0012] In a preferred embodiment of this utility model, a suitable rubber pad is fixedly glued to the inner arc surface of the first clamping plate.

[0013] In a preferred embodiment of this utility model, rubber pads are fixedly glued to the four corners of the bottom of the base.

[0014] In a preferred embodiment of this utility model, a limiting rod is fixedly installed on one side of the top of the lifting plate, and the limiting rod moves through the horizontal plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The present application provides an automatic separation tube cap device, which positions the tube body using a tube positioning component. Then, the cover is lowered by the first electric push rod, allowing it to be fitted onto the tube cap. The second electric push rod then drives the second clamping plate to hold the tube cap, and the tube cap is then moved upwards, thereby achieving rapid separation of the tube body and the tube cap. This improves operational convenience, saves manpower, and helps prevent blood sample spillage caused by tube shaking.

[0017] The servo motor drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn causes the shaft to rotate. When the tube cap is pulled upward, the cover causes the tube cap to rotate, which helps to improve the separation effect of the tube cap and the tube body and improves the separation efficiency.

[0026] Please see Figure 1-3 This utility model provides a technical solution: an automatic separation type blood collection tube cap device, including a base 1, a carrier block 11 fixedly installed on the top of the base 1, a positioning hole opened on the top of the carrier block 11, and a tube positioning component set in the positioning hole;

[0027] A support plate 13 is fixedly installed on one side of the top of the base 1. A horizontal plate 14 is fixedly installed on the upper side of one side wall of the support plate 13. A first electric push rod 15 is fixedly installed on the top of the horizontal plate 14. The push rod of the first electric push rod 15 moves through the horizontal plate 14 and is fixedly connected to a lifting plate 17. A rotating shaft 2 is rotatably installed at the bottom middle of the lifting plate 17. A cover 24 is fixedly connected to the tail end of the rotating shaft 2. A second clamping plate 26 is provided on both sides of the inner cavity of the cover 24. A second electric push rod 25 is fixedly installed on both sides of the cover 24. The push rod of the second electric push rod 25 moves through the cover 24 and is fixedly connected to the corresponding second clamping plate 26.

[0028] It should be understood that in actual use, the tube is placed in the positioning hole and positioned by the tube positioning component. Then, the first electric actuator 15 drives the lifting plate 17 to descend, so that the cover 24 is placed on the tube cap. Then, the second electric actuator 25 is activated to move the second clamping plates 26 on both sides, so that the tube cap is clamped by the two second clamping plates 26. Then, the first electric actuator 15 drives the lifting plate 17 to rise, thereby realizing the rapid separation of the tube and the tube cap without manual operation, which is conducive to improving the convenience of operation, saving manpower, and also helps to avoid blood splattering due to tube shaking.

[0029] Furthermore, a limit rod 16 is fixedly installed on one side of the top of the lifting plate 17. The limit rod 16 moves through the horizontal plate 14. The setting of the limit rod 16 makes the lifting plate 17 driven by the first electric push rod 15 highly stable.

[0030] Furthermore, rubber pads are fixedly glued to the four corners of the bottom of the base 1. The rubber pads allow the device to slide smoothly when placed on a table.

[0031] like Figure 1 and 2 As shown; a second gear 23 is fixedly mounted on the outer wall of the rotating shaft 2, and a first gear 22 meshes with the outer wall of the second gear 23. The first gear 22 is fixed to the outer end of the transmission shaft of the servo motor 21, and the servo motor 21 is fixedly installed on the lower side of the lifting plate 17.

[0032] It should be understood that the servo motor 21 can drive the first gear 22 to rotate, which in turn drives the second gear 23 to rotate, thereby driving the rotating shaft 2 to rotate. When the tube cap is pulled upward, the cover 24 drives the tube cap to rotate, which helps to improve the effect of separating the tube cap and the tube body and improves the separation efficiency.

[0033] like Figure 1 and 3 As shown; the tube positioning assembly includes a first clamping plate 12, which is disposed on both sides of the positioning hole cavity. A sliding cavity is opened on the top of the base 1. A dual-axis motor 3 is fixedly installed in the middle of the inner cavity of the sliding cavity. Both ends of the dual-axis motor 3 are fixedly connected to lead screws 31. The outer end of the lead screw 31 is rotatably connected to the inner wall of the sliding cavity. A matching lead screw slider 32 is fitted on the outer wall of the lead screw 31. The top of the lead screw slider 32 is fixedly connected to the corresponding first clamping plate 12.

[0034] It should be understood that the dual-axis motor 3 drives the lead screws 31 on both sides to rotate, thereby driving the lead screw sliders 32 on both sides to move, so that the first clamping plates 12 on both sides clamp the tube body, thereby achieving tube body positioning.

[0035] Furthermore, a suitable rubber pad is fixedly glued to the inner arc surface of the first clamping plate 12. The rubber pad increases friction when the first clamping plate 12 clamps the tube, thereby improving the stability of the tube positioning.

[0036] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the specific embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
