Description

Technical Field

[0001] This invention relates to a vaccine activity detection extractor and its usage method, belonging to the field of vaccine detection technology. Background Technology

[0002] Vaccines are immunizing agents used to prevent infectious diseases. They are made by artificially attenuating, inactivating, or using genetic engineering methods to produce pathogenic microorganisms (such as bacteria, rickettsiae, viruses, etc.) and their metabolic products. Vaccines retain the characteristic of pathogens stimulating the animal's immune system. When an animal comes into contact with this harmless pathogen, the immune system produces certain protective substances, such as immune hormones, active physiological substances, and specific antibodies. When the animal comes into contact with the pathogen again, the animal's immune system will follow its original memory and produce more protective substances to prevent the pathogen from causing harm.

[0003] Vaccines are stored in vials and kept at low temperatures. In current technology, when extracting vaccines, medical personnel usually hold the vials by hand. Since extracting vaccines takes a certain amount of time, the body temperature during this time will cause the temperature of the vaccine in the vial to rise, which will affect the activity of the vaccine.

[0004] For example, the Chinese utility model patent CN201821963621.X discloses a "vaccine extractor." Its instruction manual states that vaccines are generally stored in ampoules, while the human body temperature is mostly around 37 degrees Celsius. When medical personnel remove the ampoules, they need to remove the tops, requiring them to touch the ampoules. The body temperature causes the temperature of the vaccine inside the ampoule to drop, easily leading to loss of drug activity and affecting its normal efficacy.... This patent demonstrates the defects in the existing technology.

[0005] Therefore, we have made improvements to this by proposing a vaccine activity detection extractor and its usage method. Summary of the Invention

[0006] (a) The technical problem to be solved by the present invention is that the temperature of the human body affects the activity of the vaccine during the extraction of the vaccine.

[0007] (II) Technical Solution

[0008] To achieve the above-mentioned objectives, the present invention provides a vaccine activity detection extractor, including a support base and a handle fixedly installed on one side of the support base. An extraction mechanism is provided between the support base and the handle, and a driving mechanism is provided between the support base, the extraction mechanism and the handle.

[0009] The extraction mechanism includes a positioning part disposed in the support base, an adjustable clamping part disposed on the positioning part, and a control part disposed between the adjustable clamping part and the handle;

[0010] The drive mechanism includes a transmission part disposed between the support base and the positioning part, and a switching part is provided between the transmission part and the control part.

[0011] A method of using a vaccine activity detection extractor, comprising the vaccine activity detection extractor and further comprising:

[0012] S1. Horizontal clamping: Push the control unit in the extraction mechanism, and the control unit drives the adjustable clamping part to expand. Place the expanded adjustable clamping part on the outside of the vaccine bottle. Release the control unit, and the adjustable clamping part will retract and clamp the vaccine bottle.

[0013] S2. Vertical clamping: Pull the adjustable control unit and rotate it to switch the position of the adjustable control unit. Then, drive the adjustable clamping part to expand through the control unit. Place the expanded adjustable clamping part on the outside of the vaccine bottle from the vertical direction. Release the control unit. At this time, the adjustable clamping part will retract and clamp the vaccine bottle.

[0014] S3. Use as a drug mixing structure: Lay the support base down so that the adjustable clamping part faces upward. Pull the adjustable control part and rotate it. Through the cooperation of the control part and the switching part, the transmission part is driven by the adjustable control part. The medicine bottle is clamped on the adjustable clamping part. The control part is pushed back and forth to make the adjustable control part rotate back and forth, so as to achieve the mixing of the medicine in the medicine bottle.

[0015] (III) Beneficial Effects

[0016] The vaccine activity detection extractor and its usage method provided by this invention have the following advantages:

[0017] 1. Through the extraction mechanism, the control unit in the extraction mechanism can control the adjustable clamping part, which can clamp the vaccine vial, so that the medical staff's hands do not come into contact with the vaccine vial during the extraction process, thereby reducing the impact of body temperature on vaccine activity;

[0018] 2. Through the set extraction mechanism, the adjustable clamping part in the extraction mechanism can clamp the vaccine bottle horizontally from the horizontal direction, and after the position of the adjustable clamping part is adjusted, it can clamp the vaccine bottle vertically, which is suitable for different usage scenarios.

[0019] 3. With the adjustable clamping part and drive mechanism, the adjustable clamping part can rotate after the position is switched, and the transmission part in the drive mechanism can drive the adjustable clamping part to rotate under the control of the switching part, so that the extractor can be used as a drug mixing structure, that is, it can mix the drugs in the medicine bottle, thus improving the functionality of this application.

[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, this embodiment proposes a vaccine activity detection extractor, including a support base 1 and a handle 4 fixedly installed on one side of the support base 1. An extraction mechanism 2 is provided between the support base 1 and the handle 4, and a driving mechanism 3 is provided between the support base 1, the extraction mechanism 2 and the handle 4.

[0037] The extraction mechanism 2 includes a positioning part disposed in the support base 1, an adjustable clamping part disposed on the positioning part, and a control part disposed between the adjustable clamping part and the handle 4.

[0038] The drive mechanism 3 includes a transmission part disposed between the support base 1 and the positioning part.

The adjustable clamping part can clamp the vaccine bottle, so that the medical staff's hands do not come into contact with the vaccine bottle during the vaccine extraction process, thereby reducing the impact of body temperature on the vaccine activity.

[0039] Example 2

[0040] The solution in Example 1 will be further described below with reference to its specific working method.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the positioning part further includes a cavity 201 opened on the front of the support base 1, a fixed plate 202 is fixedly installed in the cavity 201, and four positioning grooves 203 are opened on the fixed plate 202. The four positioning grooves 203 are arranged in a ring and are equidistantly distributed.

[0042] A rotating shaft 204 is rotatably connected to the inner wall of the chamber 201 via a bearing. One end of the rotating shaft 204 passes through a fixed plate 202 and is fixedly connected to a connecting plate 205. A gap is left between the rotating shaft 204 and the fixed plate 202 so that the rotation of the rotating shaft 204 is not affected by the fixed plate 202. A turntable 206 located in the chamber 201 is fixedly installed on the side of the connecting plate 205 away from the rotating shaft 204. A first sliding groove 207 is provided in the middle of the turntable 206. The setting of the connecting plate 205 facilitates the connection of the rotating shaft 204 and the turntable 206 together.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the adjustable clamping part further includes a slide rod 208 fixedly installed in the first slide groove 207. Two support plates 209 are provided in the first slide groove 207. One support plate 209 is fixedly connected to the inner wall of the first slide groove 207, and the other support plate 209 is slidably connected to the inner wall of the first slide groove 207. A sliding plate 217 is fixedly installed on one side of the other support plate 209. The sliding plate 217 is slidably connected to the outer surface of the slide rod 208. The support plate 209 connected to the sliding plate 217 can be supported by the cooperation of the sliding plate 217 and the slide rod 208.

[0044] The outer surface of the slide bar 208 is fitted with a second spring 218 located on one side of the slide plate 217. The two ends of the second spring 218 are fixedly connected to the slide plate 217 and the first slide groove 207, respectively. The force of the second spring 218 can push the slide plate 217 to move, so that the two support plates 209 can get closer.

[0045] like Figure 1 , Figure 3 and Figure 5As shown, in a preferred embodiment, based on the above method, a second sliding groove 210 is further provided in the middle of each of the two support plates 209. A support rod 211 is fixedly installed in each of the two second sliding grooves 210. A slider 212 is slidably connected to the outer surface of each of the two support rods 211. A connecting rod 213 is rotatably connected to the end of each of the two sliders 212 that is close to each other through a bearing. A clamping plate 214 is fixedly connected to the end of each of the two connecting rods 213 that is close to each other. The slider 212 contacts the clamping plate 214. The friction between the slider 212 and the clamping plate 214 can limit the clamping plate 214 so that the clamping plate 214 can stay in the corresponding position after rotation.

[0046] Both clamping plates 214 have notches 215 on one side. One side of the clamping plate 214 is inserted into the positioning groove 203. By inserting the clamping plate 214 into the positioning groove 203, the turntable 206 can be limited to prevent the turntable 206 from rotating during the clamping of the vaccine bottle, which is convenient for use. The notch 215 is slidably connected to the outer surface of the slide rod 208. The outer surface of the support rod 211 is fitted with a first spring 216. The two ends of the first spring 216 are fixedly connected to the second slide groove 210 and the slider 212, respectively. The force of the first spring 216 can improve the stability of the clamping plate 214 inserted into the positioning groove 203.

[0047] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the control unit further includes a third slide groove 220 opened in the middle of the handle 4 and a through hole 221 opened between the support base 1 and the handle 4. Two guide wheels 222 are installed in the through hole 221. A connecting seat 227 is slidably connected in the third slide groove 220. A pull ring 224 is provided on one side of the connecting seat 227. A wire hole 219 is opened on the pull ring 224.

[0048] The pull ring 224 has multiple slots 225 on its outer side. One of the slots 225 has a post 226 inserted into it. The post 226 has a magnet on it and the magnet is in contact with the inner wall of the slot 225. A transmission rope 223 is fixedly connected to one side of the post 226. One end of the transmission rope 223 passes through the wire hole 219, the through hole 221 and the turntable 206 in sequence and is fixedly connected to the sliding plate 217. The transmission rope 223 passes through two guide wheels 222. The two guide wheels 222 are arranged one above the other. The two guide wheels 222 can guide and position the transmission rope 223.

[0049] In a preferred embodiment, based on the above method, the transmission unit further includes a gear 301 fixedly sleeved on the outer surface of the rotating shaft 204, and the gear 301 is located on the side of the fixed plate 202 away from the rotating plate 206. A rack 302 is provided above the gear 301, and one end of the rack 302 passes through the support base 1 and extends into the third slide groove 220. Figure 1 and Figure 7 In this state, rack 302 and gear 301 are not in contact, but... Figure 9 In this state, rack 302 meshes with gear 301.

[0050] like Figure 2 and Figure 7 As shown, in a preferred embodiment, based on the above method, the switching part further includes a fourth slide groove 303 formed on the connecting seat 227. Two uprights 304 are fixedly installed in the fourth slide groove 303. A transmission plate 305 is slidably connected between the outer surfaces of the two uprights 304. The end of the transmission plate 305 extends out of the fourth slide groove 303 and is fixedly connected to one end of the rack 302. A third spring 306 located above the transmission plate 305 is sleeved on the outer surface of the uprights 304. The transmission plate 305 can be supported by the two uprights 304.

[0051] like Figure 7 As shown, in a preferred embodiment, based on the above method, a circular groove 307 is provided on the side of the connecting seat 227 near the pull ring 224, and a square groove 308 is provided on the side of the circular groove 307 near the pull ring 224. A block 309 is inserted and connected in the square groove 308. The block 309 cannot rotate in the square groove 308. The side of the block 309 away from the circular groove 307 is fixedly connected to the pull ring 224. A connecting post 310 is fixedly connected to the side of the block 309 away from the pull ring 224. A cylinder 311 located in the circular groove 307 is fixedly connected to the end of the connecting post 310 away from the block 309. The cylinder 311 can rotate in the circular groove 307.

[0052] like Figure 7 As shown, in a preferred embodiment, based on the above method, a square cavity 312 is further provided inside the cylinder 311. A square plate 313 is slidably connected inside the square cavity 312. A rotating rod 314 is fixedly connected to the side of the square plate 313 away from the connecting column 310. One end of the rotating rod 314 away from the square plate 313 passes through the square cavity 312 and extends into the fourth sliding groove 303. The other end of the rotating rod 314 away from the square plate 313 is connected to the side wall of the fourth sliding groove 303 through a bearing. A cam 315 located in the fourth sliding groove 303 is fixedly sleeved on the outer surface of the rotating rod 314. The outer surface of the cam 315 contacts the bottom of the transmission plate 305. Figure 7 In this state, the protruding part of the cam 315 contacts the transmission plate 305, causing the transmission plate 305 to drive the rack 302 to separate from the gear 301;

[0053] The outer surface of the rotating rod 314 is fitted with a fourth spring 316 located in the square cavity 312. The two ends of the fourth spring 316 are fixedly connected to the square plate 313 and the square cavity 312 respectively. The force of the fourth spring 316 can improve the stability of the block 309 located in the square groove 308.

[0054] Example 3

[0055] This embodiment proposes a method for using a vaccine activity detection extractor, including the vaccine activity detection extractor, and further comprising:

[0056] S1. Horizontal clamping: Push the control unit in the extraction mechanism 2, and drive the adjustable clamping part to expand. Place the expanded adjustable clamping part on the outside of the vaccine bottle. Release the control unit, and the adjustable clamping part will retract and clamp the vaccine bottle.

[0057] The specific steps are as follows, please refer to... Figure 1 Hold the handle 4, insert your fingers into the pull ring 224 and push the pull ring 224. The pull ring 224 pulls the sliding plate 217 through the transmission rope 223, which in turn moves the support plate 209 on the sliding plate 217, causing the two clamping plates 214 to move away from each other. After placing the two clamping plates 214 on the outside of the vaccine bottle, release the pull ring 224. At this time, the force of the second spring 218 pushes the support plate 209 on the sliding plate 217 to move, causing the two clamping plates 214 to move closer together and clamp the vaccine bottle.

[0058] S2. Vertical clamping: Pull the adjustable control unit and rotate it to switch the position of the adjustable control unit. Then, drive the adjustable clamping part to expand through the control unit. Place the expanded adjustable clamping part on the outside of the vaccine bottle from the vertical direction. Release the control unit. At this time, the adjustable clamping part will retract and clamp the vaccine bottle.

[0059] The specific operation is as follows: the shape of the vaccine activity detection extractor is changed from... Figure 1 Switch to Figure 8First, pull the insert 226 to separate it from the corresponding slot 225. Then, insert the insert 226 into the slot 225 near the handle 4, extending the transmission rope 223. Next, pull the two clamps 214 to separate them from the positioning groove 203. Rotate the turntable 206 clockwise by 90 degrees to release the clamps 214 and insert them into the positioning groove 203, thus completing the mode switching. Hold the handle 4, insert your fingers into the pull ring 224, and push the pull ring 224. The pull ring 224 pulls the sliding plate 217 through the transmission rope 223, which in turn moves the support plate 209 on it, causing the two clamps 214 to move away from each other. After placing the two clamps 214 vertically outside the vaccine bottle, release the pull ring 224. At this time, the force of the second spring 218 pushes the support plate 209 on it through the sliding plate 217, causing the two clamps 214 to move closer together and clamp the vaccine bottle.

[0060] Pull the two clamps 214 to separate them from the positioning grooves 203. Rotate the turntable 206 counterclockwise by 90 degrees to release the clamps 214 so that they insert into the positioning grooves 203. Then pull the insert 226 to separate it from the corresponding slot 225. Insert the insert 226 into the slot 225 away from the handle 4. This changes the shape of the vaccine activity detection extractor. Figure 8 Switch back Figure 1 ;

[0061] S3. Use as a drug mixing structure: Lay the support base 1 down so that the adjustable clamping part faces upward. Pull the adjustable control part and rotate it. Pull the control part and rotate it. Through the cooperation of the control part and the switching part, the transmission part is driven by the adjustable control part. The medicine bottle is clamped on the adjustable clamping part. The control part is pushed back and forth to make the adjustable control part rotate back and forth, so as to achieve the mixing of the medicine in the medicine bottle.

[0062] The specific operation is as follows: the shape of the vaccine activity detection extractor is changed from... Figure 1 Switch to Figure 9First, lay down the support base 1, pull the two clamps 214 to separate them from the positioning groove 203, rotate the clamps 214 ninety degrees, release the clamps 214 so that they insert into the positioning groove 203, pull the insert pin 226 to separate it from the corresponding slot 225, then insert the insert pin 226 into the slot 225 near the handle 4, so that the transmission rope 223 extends, then pull the pull ring 224 to separate the block 309 from the square groove 308, rotate it ninety degrees. Rotating block 309 causes cylinder 311 to rotate via block 309 and connecting column 310. Cylinder 312 and square plate 313 then drive rotating rod 314 to rotate. Rotating rod 314 drives cam 315 to rotate, causing the protruding part of cam 315 to separate from transmission plate 305. At this time, transmission plate 305, under the action of third spring 306, causes rack 302 to descend, allowing rack 302 to mesh with gear 301. This changes the shape of the vaccine activity detection extractor from... Figure 1 Switch to Figure 9 ;

[0063] The support plate 209 connected to the sliding plate 217 is pushed to move, and the medicine to be mixed is added to the medicine bottle. The medicine bottle is then placed between two clamping plates 214, which hold the medicine bottle in place. The pull ring 224 is pushed back and forth to move. The pull ring 224, the connecting seat 227, and the transmission plate 305 drive the rack 302 to move back and forth. The rack 302 and the gear 301 work together to drive the rotating shaft 204 to rotate back and forth. The rotating shaft 204 drives the turntable 206 to rotate through the connecting plate 205, thereby making the medicine bottle rotate back and forth to achieve mixing.

[0064] After pushing the clamping plate 214, rotate the clamping plate 214 around the connecting rod 213 so that the notch 215 aligns with the first slide groove 207. Then, insert the clamping plate 214 into the positioning groove 203. Pull the pull ring 224 to separate the block 309 from the square groove 308. Rotate the block 309 ninety degrees in the opposite direction. The block 309 and the connecting column 310 drive the cylinder 311 to rotate. The cylinder 311 and the square cavity 312 drive the rotating rod 314 to rotate through the square plate 313. The rotating rod 314 drives the cam 315 to rotate, so that the protruding part of the cam 315 contacts the transmission plate 305. At this time, the transmission plate 305, under the action of the third spring 306, drives the rack 302 to rise, so that the rack 302 separates from the gear 301. Thus, the shape of the vaccine activity detection extractor changes from... Figure 9 Switch to Figure 1 .

[0065] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
