Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, and more specifically, it relates to an adapter for a pharmaceutical testing centrifuge. Background Technology

[0002] As a specialized device for drug detection and analysis, the core function of a pharmaceutical centrifuge is to separate different components in a sample, laying the foundation for subsequent testing. It has wide applications in drug component separation, blood and urine analysis, and quality control.

[0003] When using a pharmaceutical centrifuge, the reagent tubes must be securely fixed to the rotor with the help of an adapter in order to perform the centrifugation operation. After the test tubes are fixed, the protective caps must be tightly closed on the top of the test tubes to prevent the reagents from spilling during the centrifugation process.

[0004] However, after centrifugation is complete, the protective cap needs to be removed from the test tube before pouring out the reagent. If the protective cap is too tight on the test tube, the reagent in the test tube is very likely to spill out the moment the protective cap is removed. Once this happens, it will adversely affect the subsequent test results of the centrifuged reagent, interfering with the accuracy and reliability of the test. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a pharmaceutical testing centrifuge adapter to solve the risk of spillage of pharmaceuticals inside the test tubes when the protective cap is removed from the test tubes.

[0006] This utility model provides an adapter for a pharmaceutical testing centrifuge, achieved through the following specific technical means:

[0007] An adapter for a pharmaceutical testing centrifuge includes a cap removal assembly, an upper adapter part, and a lower adapter part. The cap removal assembly includes a cap removal plate with a central upper shaft insertion hole, two rings of test tube insertion holes around the cap removal plate, a fixing collar at each test tube insertion hole, and rotatable handles on both sides of the cap removal plate. A guide rod is provided at the bottom of the cap removal plate. The upper adapter part includes an upper plate and an upper lower plate, with a shaft insertion tube connecting them centrally. The lower end of the shaft insertion tube passes through the upper lower plate and is provided with a limit plate. Two rings of connecting tubes are arranged around the sides of the shaft insertion tube. Holes are provided at the connection ends of the shaft insertion tube, connecting tubes, and upper upper and lower plates. A guide hole is provided on the upper plate, and a guide rod is provided. A sliding guide hole is provided; the lower end of the rotating shaft insert is inserted into the center of the lower part of the adapter. The lower part of the adapter includes a lower upper plate and a lower lower plate, with a lower rotating shaft insert hole in the center of both. Two arc-shaped holes are arranged around the lower rotating shaft insert hole. A sandwich is formed between the lower upper plate and the lower lower plate. The sandwich is connected to the lower upper plate and the lower lower plate near one end of the arc-shaped hole by a connecting arc plate. An arc-shaped hole is provided on one side of the lower upper plate, and a notch is provided on the edge of the other side. A limiting sleeve is provided near the notch. A fixing seat hole is provided on the lower lower plate. A medicine test tube is inserted into the test tube insert hole. The medicine test tube includes a tube body and a protective cap. The tube body passes through the connecting tube and the arc-shaped hole, and the lower end of the tube body protrudes from the lower part of the adapter.

[0008] Furthermore, the protective cap is placed on the upper end of the tube body, the side wall of the protective cap is secured within the fixing ring, and the bottom of the protective cap is secured around the test tube insertion hole of the cap removal plate.

[0009] Furthermore, each of the connecting arc plates is fitted with anti-slip rubber, which rests against the side wall of the tube.

[0010] Furthermore, a fixing plate is provided on one side of the bottom of the upper plate, and the fixing plate passes through the second arc-shaped hole; an end plate is provided at one end of the second arc-shaped hole in the lower interlayer of the adapter; an arc-shaped sleeve is provided on the fixing plate, and a spring is sleeved on the arc-shaped sleeve, with the two ends of the spring abutting against the fixing plate and the end plate respectively.

[0011] Furthermore, the bottom of the upper plate has a contact plate one on the other side, and the contact plate one has a through notch; the lower interlayer of the adapter has a contact plate two at one end of the notch, and the contact plate one and the contact plate two are in contact; the upper plate has a pin hole near the contact plate one, and a positioning pin is inserted into the pin hole, and the positioning pin passes through the limiting sleeve.

[0012] Furthermore, the cap removal plate is provided with rotatable pressure plates on both sides, and the pressure plates press against the handle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model is equipped with a cap removal component. After the reagent centrifugation is completed, the anti-slip rubber inside the connecting arc plate will press against one side of the tube body, and the other side of the tube body will press against one end of the arc-shaped hole, firmly limiting the test tube in the connecting tube. At this time, lift the handle, and the cap removal plate will separate from the upper part of the adapter. During this process, the protective cap will be stuck on the cap removal plate, thus separating smoothly from the test tube and completing the cap removal operation. The whole process is simple to operate and can ensure that the reagent inside the tube will not spill.

[0015] 2. In this utility model, when the positioning pin is pulled out from the pin hole, the limit between the upper part and the lower part of the adapter is released; under the compression of the spring, the lower part of the adapter will rotate around the pivot tube, causing the anti-slip rubber to detach from the test tube, at which point the test tube can slide freely up and down inside the connecting tube; under the action of gravity, hold the adapter and let it slowly fall to the ground, and the top of the test tube will be exposed by the cap removal plate, making it convenient to take out the tube and medicine from the adapter.

The adapter upper part 200 includes an upper plate 210 and an upper lower plate 220, with a rotating shaft tube 230 connected between them at the center. The lower end of the rotating shaft tube 230 passes through the upper lower plate 220 and is provided with a limit plate 240. Two connecting tubes 250 are provided around the side of the rotating shaft tube 230. The connecting ends of the rotating shaft tube 230, the connecting tubes 250, and the upper plate 210 and the upper lower plate 220 are all opened. A guide hole 211 is opened on the upper plate 210, and the guide rod... 116 Sliding insertion guide hole 211; The lower end of the rotating shaft insertion tube 230 is inserted into the center of the lower part 300 of the adapter. The lower part 300 of the adapter includes a lower upper plate 310 and a lower lower plate 320. A lower rotating shaft insertion hole 311 is provided in the center of the two. Two arc-shaped holes 312 are arranged around the lower rotating shaft insertion hole 311. A sandwich is formed between the lower upper plate 310 and the lower lower plate 320. The sandwich is connected to the lower upper plate 310 and the lower lower plate 320 near one end of the arc-shaped hole 312 by a connecting arc plate 330. The lower plate 320; the upper plate 310 has an arc-shaped hole 313 on one side and a notch 314 on the edge on the other side, and a limiting sleeve 315 is provided near the notch 314; the lower plate 320 has a fixing seat hole 321; a medicine test tube 400 is inserted into the test tube insertion hole 112, the medicine test tube 400 includes a tube body 410 and a protective cap 420; the tube body 410 passes through the connecting tube 250 and the arc-shaped hole 312, and the lower end of the tube body 410 protrudes from the lower part 300 of the adapter.

[0038] Among them, such as Figure 1 As shown, the protective cap 420 covers the upper end of the tube body 410, the side wall of the protective cap 420 is secured within the fixing ring 113, and the bottom of the protective cap 420 is secured around the test tube insertion hole 112 of the cap removal plate 110; as shown Figure 8 As shown, each of the connecting arc plates 330 is fitted with anti-slip rubber 500, which rests against the side wall of the tube body 410. The tube body 410 of the reagent test tube 400 can slide freely up and down within the connecting tube 250. After the anti-slip rubber 500 placed inside the connecting arc plate 330 is engaged on one side of the tube body 410, the other side of the tube body 410 is engaged at one end of the arc-shaped hole 312, which can limit the movement of the tube body 410. Anti-slip rubber can also be provided at the end with the arc-shaped hole 312.

[0039] Among them, such as Figure 5As shown, a fixing plate 221 is provided on one side of the bottom of the upper lower plate 220, and the fixing plate 221 passes through the arc-shaped hole 313; as Figure 6 As shown, an end plate 340 is provided at one end of the arc-shaped hole 313 inside the lower 300 layer of the adapter; as Figure 5 As shown, an arc-shaped sleeve 222 is provided on the fixing plate 221, such as... Figure 10 As shown, a spring 600 is fitted on the arc-shaped sleeve 222. The two ends of the spring 600 abut against the fixed plate 221 and the end plate 340 respectively. At this time, the spring 600 is in a compressed state.

[0040] Among them, such as Figure 5 As shown, a contact plate 223 is provided on the other side of the bottom of the upper lower plate 220. The contact plate 223 passes through the notch 314 and serves as a rotation limiter; Figure 7 As shown, a contact plate 350 is provided at one end of the notch 314 inside the lower 300 interlayer of the adapter. Figure 11 As shown, contact plate 223 and contact plate 350 are in contact, and their cooperation allows for adjustment of the relative angle between the upper and lower parts. The lower upper plate 220 has a pin hole 224 near contact plate 223, into which a positioning pin 700 is inserted. The positioning pin 700 passes through a limiting sleeve 315. After the positioning pin 700 is pulled out of the pin hole 224, the limiting between the upper part 200 and the lower part 300 of the adapter is released. Under the compression of the spring 600, the lower part 300 of the adapter rotates around the pivot tube 230, causing the anti-slip rubber 500 to detach from the tube body 410. The tube body 410 itself can then move freely within the connecting tube 25. Slide up and down within 0; pinch contact plate 1 223 and contact plate 2 350 to rotate the entire lower part 300 of the adapter around the pivot tube 230, so that contact plate 1 223 and contact plate 2 350 gradually approach and eventually contact each other. At this time, the connecting tube 250 of the upper part 200 of the adapter is aligned with the arc-shaped hole 1 312 of the lower part 300 of the adapter. Insert tube body 410 into test tube insertion hole 112. Tube body 410 passes through connecting tube 250 and arc-shaped hole 1 312 at the same time. Anti-slip rubber 500 abuts against one side of tube body 410, and the other side of tube body 410 abuts against one end of arc-shaped hole 1 312, limiting tube body 410 within connecting tube 250.

[0041] Among them, such as Figure 1 As shown, the cap removal plate 110 is provided with a rotatable pressure plate 115 and a handle 114 on both sides. The movable end of the pressure plate 115 faces away from the center and presses on the handle 114. The cap removal plate 110 and the upper part 200 of the adapter can be separated by the handle 114. During the centrifugation process, the handle 114 is rotated to press it under the pressure plate 115, and the centrifugal force presses down the handle 114 to prevent the handle 114 from swinging.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In this invention, the reagent to be centrifuged and tested is filled into the tube body 410 of the reagent test tube 400, and a protective cap 420 is placed on the upper end of the tube body 410; the contact plate 223 and the contact plate 350 are pinched to rotate the lower part 300 of the adapter around the pivot tube 230, so that the contact plate 223 and the contact plate 350 gradually approach each other and eventually make contact. At this time, the connecting tube 250 of the upper part 200 of the adapter is aligned with the arc-shaped hole 312 of the lower part 300 of the adapter, and the pin is inserted into the pin hole 224. Insert the positioning pin 700 and insert the tube body 410 into the test tube insertion hole 112. The tube body 410 simultaneously passes through the connecting tube 250 and the arc-shaped hole 312. At this time, the anti-slip rubber 500 abuts against one side of the tube body 410, and the other side of the tube body 410 abuts against one end of the arc-shaped hole 312, limiting the tube body 410 within the connecting tube 250. Then, place the reagent test tube 400 and the adapter into the centrifuge. The centrifuge shaft passes through the shaft insertion tube 230, and the adapter is fixed through the fixing seat hole 321. The agent is centrifuged on the rotor or turntable of a centrifuge. After an appropriate time, the adapter is removed from the centrifuge. The cap removal assembly 100 is lifted upwards using the handle 114 to separate the cap removal plate 110 from the upper part 200 of the adapter. During this process, the protective cap 420 separates from the tube body 410 along with the cap removal plate 110 within the fixing ring 113, completing the cap removal process. The adapter is then placed on a flat surface, and the adapter is lifted up to a certain height above the surface using the tube body 410. It is then pulled out from the pin hole 224. After the positioning pin 700 is engaged, the limiting position between the upper part 200 and the lower part 300 of the adapter is released. Under the compression of the spring 600, the lower part 300 of the adapter rotates around the pivot tube 230, causing the anti-slip rubber 500 to detach from the tube 410. The tube 410 itself can slide freely up and down inside the connecting tube 250. Under the action of gravity, the adapter is supported and slowly falls to the ground, while the upper end of the tube 410 is exposed by the cap removal plate 110, making it easy to remove the tube 410 and the medicine from the adapter.

[0044] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
