[0002] The nicorandil trial is a series of studies conducted on the nicorandil drug to comprehensively evaluate its application value in the medical field. Taking the CHANGE trial as an example, this is a domestic multicenter prospective randomized controlled interventional clinical study that included patients with acute ST-segment elevation myocardial infarction and divided them into the nicorandil group and the placebo control group.

[0003] Currently, due to differences in experimental scenarios and sample types, the core components of blood collection devices used in clinical trials include blood collection needles, blood collection tubes, and auxiliary tools. Blood collection needles mostly adopt butterfly or straight needle designs. Butterfly needles are highly flexible and suitable for blood vessels that are difficult to puncture, while straight needles are more stable and can ensure the smooth progress of the blood collection process. In the past, nicorandil test sampling was carried out using a syringe, but now it is carried out using a special nicorandil test sampling device, thereby improving its sealing. However, the sampling needle of the existing nicorandil test sampling device is inserted from the front and cannot be removed separately after insertion, which limits the number of samples that can be collected at one time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nicotinic acid test sampling device, which aims to improve the problem in the prior art that the sampling needle cannot be removed individually after insertion, thus limiting the number of samples taken at one time.

[0009] As a preferred embodiment, the inner center of each of the two buckles is equidistantly connected to a plurality of rotating rods, and the outer walls of the plurality of rotating rods are fixedly connected to pulleys.

[0010] As a preferred embodiment, rubber pads are fixedly connected to the front and rear sides of both pull rods, and anti-slip textures are formed on the outer walls of the multiple rubber pads.

[0011] As a preferred embodiment, the outer wall of the connecting ring is provided with a plurality of threaded holes at equal intervals, and screws are threaded to the inner side of each of the plurality of threaded holes.

[0012] As a preferred embodiment, a sealing ring is installed on the outer wall of the tray, and thumbtacks are fixedly connected to the outer wall of the sealing ring at equal intervals.

[0013] As a preferred embodiment, the front sides of the machine body and the tray are equidistantly connected with a plurality of insert rods, and the front ends of the plurality of insert rods are fixedly connected with a blocking disc.

Rubber pads 12 are fixedly connected to the front and rear sides of the two pull rods 9. Anti-slip textures 13 are opened on the outer walls of the multiple rubber pads 12. The anti-slip textures 13 are used to improve the anti-slip properties of the rubber pads 12.

[0027] In this embodiment, pulling the lever 9 installed on the baffle 3 causes the steel wire 8 to move backward, thereby pulling the corresponding buckle 6 back into the corresponding groove 5 on the buckle 4. Then, the lever 9 is pulled out, and the sampling needle is removed. The baffle 3 is then reinserted into the body 1. At this time, multiple springs 7 will push out the corresponding buckle 6 to fix it. The pulley 11 fixed by the rotating rod 10 can improve the smoothness of the steel wire 8. The rubber pad 12 fixed outside the lever 9 improves its grip by the anti-slip texture 13.

[0028] Please see Figure 4 and Figure 5 As shown, the fixing mechanism 2 includes a tray 201. The rear side of the tray 201 is located on the front side of the body 1. Multiple fixing buckles 202 are fixedly connected at equal intervals on the rear side of the tray 201. Fixed grooves 203 are opened at equal intervals on the front end of the body 1. The multiple fixing grooves 203 are slidably connected to the corresponding fixing buckles 202. The tray 201 is fixed to the body 1 through the cooperation of the fixing buckles 202 and the fixing grooves 203. Multiple insertion holes 204 are opened at equal intervals on the outer wall of the tray 201. Limiting strips 205 are slidably connected to the inner side of each of the multiple insertion holes 204. Connecting rings 206 are fixedly connected to the front end of each of the multiple limiting strips 205. The multiple limiting strips 205 are inserted into the corresponding insertion holes 204 through the connecting rings 206. Multiple threaded holes 14 are opened at equal intervals on the outer wall of the connecting rings 206. Screws 15 are threadedly connected to the inner side of each of the multiple threaded holes 14. The threaded holes 14 are used to fix the screws 15.

[0029] In this embodiment, the multiple fixing buckles 202 fixed to the back of the tray 201 are aligned with the multiple fixing slots 203 corresponding to those on the front of the body 1. Then, the multiple fixing buckles 202 are inserted into the corresponding fixing slots 203 and rotated to the right. Then, the connecting ring 206 is grasped and the multiple limiting strips 205 fixed thereon are aligned with the corresponding insertion holes 204 on the tray 201. Then, the connecting ring 206 is pushed to insert the multiple limiting strips 205 into the corresponding insertion holes 204, thereby restricting the position of the fixing buckles 202 to prevent them from sliding. The screw 15 fixed in the threaded hole 14 can fix the connecting ring 206.

[0030] Please see Figure 1 , Figure 4 and Figure 5As shown, a sealing ring 16 is installed on the outer wall of the tray 201. Thumbtacks 17 are fixedly connected at equal intervals to the outer wall of the sealing ring 16. The thumbtacks 17 are used to fix the sealing ring 16. Multiple insert rods 18 are slidably connected at equal intervals to the front side of the machine body 1 and the tray 201. A blocking disc 19 is fixedly connected to the front end of each insert rod 18. The insert rod 18 is used to fix the blocking disc 19. A threaded groove 20 is opened on the inner wall of the machine body 1. A rotating shaft 21 is threadedly connected to the inner side of the threaded groove 20. The threaded groove 20 is used to fix the rotating shaft 21. The sealing ring 16, fixed by the thumbtacks 17, facilitates the sealing effect of the outer tray 201. The blocking disc 19 installed at the front of the machine body 1 by the insert rods 18 prevents the nicorandil test sampling device from being left empty. The rotating shaft 21, fixed by the threaded groove 20, facilitates the gripping of the nicorandil test sampling device.

[0031] In this embodiment, when the sampling needle needs to be removed during sampling using the Nicorandil testing sampling device, first pull the lever 9 installed on the baffle 3. The lever 9 drives the steel wire 8 to move backward, thereby pulling the corresponding buckle 6 back into the corresponding groove 5 opened on the buckle 4. Then, the baffle 3 is pulled out. After sampling, the baffle 3 is reinserted into the body 1. At this time, multiple springs 7 will push out the corresponding buckle 6 to fix it, thus achieving the effect of removing the sampling needle after the Nicorandil testing sampling device is installed. When installing the tray 201 onto the body 1, first align the multiple fixing buckles 202 fixed to the back of the tray 201 with the multiple fixing slots 203 corresponding to those on the front of the body 1. Then, insert the multiple fixing buckles 202 into the corresponding fixing slots 203 and rotate them to the right. Next, grasp the connecting ring 206 and align the multiple limiting strips 205 fixed on it with the corresponding insertion holes 204 on the tray 201. Then, push the connecting ring 206 to insert the multiple limiting strips 205 into the corresponding insertion holes 204, thereby restricting the position of the fixing buckles 202 and preventing them from sliding. This achieves a convenient fixing effect for the tray 201.
