Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a uric acid testing device for endocrinology. Background Art

[0002] Uric acid is the final product of purine metabolism, and abnormal levels of it are often closely related to various diseases of the endocrine system. As a medical branch that manages hormones and metabolism in the body, endocrinology has important clinical significance for monitoring uric acid levels. An increase in uric acid levels is usually associated with endocrine diseases such as gout, hyperuricemia, diabetes, obesity, and metabolic syndrome.

[0003] When testing uric acid, sample collection and preparation are also required. For example, for synovial fluid samples: draw synovial fluid from the affected joint of the patient with a sterile syringe. For example, for urine samples: collect fresh urine and immediately perform centrifugation to separate the precipitate. Drop the synovial fluid sample on a glass slide, cover it with a cover slip, drop the centrifuged urine precipitate on a glass slide, cover it with a cover slip, and observe the sample with a subsequent microscope, adjust the focus to find urate crystals, or add the urine sample to a reaction test tube or an automated instrument containing uricase and buffer to start the uric acid oxidation reaction. Subsequently, place the reacted solution in a spectrophotometer and measure the absorbance at a specific wavelength.

[0004] For the above two testing methods, technicians need to manually drop the extracted liquid on the glass slide or pour it into the test tube, and the amount is not easy to control. If the amount is difficult to control in a single sampling, multiple samplings and detections are required, and the process is cumbersome and time-consuming. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a uric acid testing device for endocrinology, aiming to alleviate the above problems to at least a certain extent.

The collecting boxes can move before the lifting component lifts the lifting frame, and the collecting boxes return to their original positions after moving to a preset position.

[0013] Preferably, the lifting component includes a first rod connected to the base. A second rod slidably connected to the first rod is connected to the bottom of the lifting frame. A limiting piece is connected to the second rod. A lead screw is provided on the base, and a sliding frame slidably connected to the second rod is threadedly connected to the lead screw.

[0014] Preferably, a first spring is connected between the first rod and the second rod.

[0015] Preferably, a first gear is connected to the lead screw. A screw tube is rotatably connected to the fixed frame. A screw rod slidably connected to the fixed frame is threadedly connected inside the screw tube. The positioning piece is connected to the screw rod. A second gear meshing with the first gear is connected to the screw tube. A preset distance is provided between the sliding frame and the limiting piece.

[0016] Preferably, a connecting ring is connected to the outside of the screw tube. The connecting ring is rotatably connected to the inside of the second gear. A plurality of clamping grooves are formed on the inner side wall of the second gear. A plurality of connecting grooves are formed on the outer side wall of the connecting ring. A top contact rod adapted to the clamping groove is slidably sleeved in the connecting groove. One end of the top contact rod in the clamping groove is semi-spherical. A second spring is connected between the top contact rod and the connecting groove.

[0017] Preferably, the collecting component includes a collecting box provided on the base. A first tube is connected to the collecting box. A second tube is slidably connected to the first tube. The second tube is communicated with the collecting box.

[0018] Preferably, the collecting component further includes a rotating frame connected to the lead screw. A connecting rod is rotated on the rotating frame. The other end of the connecting rod is connected to the collecting box.

[0019] Preferably, a box body is connected to the top of the base. The lead screw is rotatably connected to the box body. A motor is provided inside the box body. The driving shaft of the motor is connected to the lead screw.

[0020] Preferably, a test tube rack is connected to the top of the base.

[0021] Preferably, a slide rack is connected to the top of the test tube rack. A top opening is formed on the top of the slide rack.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] By setting up a lifting frame, during application, the operator can suck the extracted joint fluid or centrifuged urine into the syringe through the syringe, and then place the syringe into the placement opening on the lifting frame. The multiple placement openings provided can allow the staff to place multiple syringes filled with liquid. A glass slide corresponding to the position of the syringe needle tube or a test tube containing a reaction solvent can be placed on the base. Specifically, the operator can activate the lifting component. When the lifting component moves upward, the position of multiple positioning pieces can be adjusted between the lifting frame. The multiple positioning pieces can move towards the piston shaft on the syringe. At this time, the collection box in the collection component can move. The collection box moves towards the bottom of the syringe. After the multiple positioning pieces contact and push against the piston shaft of the syringe to fix the piston shaft, when the collection box is in a position where it can receive the liquid flowing out of the syringe, the lifting component moves the lifting frame upward. The movement of the lifting frame can lift the syringe using the flange on the syringe, while the piston shaft of the syringe is restricted by the positioning piece and remains stationary. When the needle tube moves upward, the liquid can be squeezed through the piston of the piston shaft, allowing the liquid to flow out from the needle tube of the syringe. The liquid flowing out from the syringe in the early stage can be collected by the collection box that slides to its bottom. Because when the operator uses the syringe to extract liquid, if the extraction force is relatively large, some air may enter the needle tube of the syringe. The air bubbles generated in the liquid discharged at the initial stage of the syringe can be received by the collection box. As the lifting frame continues to move upward, the collection box gradually moves away from the bottom of the syringe, and the liquid is no longer received by the collection box and can flow onto the test tube or glass slide placed on the base. By controlling the distance that the lifting component moves the lifting frame upward, the amount of liquid discharged from the syringe after the collection box leaves the bottom of the syringe can be controlled to adapt to dropping and loading different containers and carriers. When the operator specifically uses the syringe to extract liquid, different forces will cause the piston shaft to move different distances. In this application, the positioning piece is used to fix the piston shaft, and the lifting frame is used to move the syringe, which can ensure that the movement distances of multiple syringes placed on the lifting frame are consistent, so that the amounts of liquid discharged from multiple syringes are the same, and it will not cause different amounts of liquid carried on each test tube or glass slide due to the piston shafts of multiple syringes being of different lengths, thus avoiding problems that affect subsequent further testing of uric acid. This solves the problem in the prior art that technicians need to manually drop and load the extracted liquid onto a glass slide or pour it into a test tube, and the amount is not easy to control. If the amount of a single sample is difficult to control, multiple samplings and detections are required, and the process is cumbersome and time-consuming. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] ReferenceFigures 1 - 10 , a uric acid testing device for the endocrinology department, comprising:

[0042] a base 100;

[0043] a fixing frame 101 provided on the top of the base 100, and a plurality of positioning pieces 102 are provided on the fixing frame 101;

[0044] a lifting frame 103 provided outside the fixing frame 101, and a plurality of object placing openings 104 for placing syringes are formed on the lifting frame 103;

[0045] a lifting component provided between the base 100 and the fixing frame 101 for lifting the lifting frame 103, and the lifting component can move the position of the positioning piece 102 before lifting the lifting frame 103;

[0046] a collecting component provided on the base 100 for collecting the liquid released by the syringe, the collecting component includes a plurality of slidable collecting boxes 105, the collecting boxes 105 can move the collecting boxes 105 before the lifting component lifts the lifting frame 103, and the collecting boxes 105 return to the original position after moving to a preset position;

[0047] By setting up the lifting frame 103, when in use, the operator can absorb the extracted joint fluid or the centrifuged urine into the syringe through the syringe, and then place the syringe in the storage port 104 on the lifting frame 103. The multiple storage ports 104 are provided for the staff to place multiple syringes with absorbed liquids, and glass slides or test tubes containing reaction solvents corresponding to the positions of the syringe needles can be placed on the base 100. Specifically, the operator can start the lifting component, and when the lifting component moves upward, the lifting frame 103 can move the positions of multiple positioning pieces 102, and the multiple positioning pieces 102 can move toward the piston shaft on the syringe. At this time, the collection box 105 provided in the collecting component can The collecting box 105 moves toward the bottom of the syringe, and after the plurality of positioning pieces 102 contact and abut the piston shaft of the syringe to fix the piston shaft, when the collecting box 105 is in a position to receive the liquid flowing out of the syringe, the lifting component moves upward to the position of the lifting frame 103, and the movement of the lifting frame 103 can lift the syringe by using the flange on the syringe, while the piston shaft of the syringe is limited by the positioning piece 102 and remains stationary. When the syringe moves upward, the piston of the piston shaft can squeeze the liquid, allowing the liquid to flow out of the syringe needle. The liquid flowing out of the syringe in the early stage can be slid to the collecting box 105 at its bottom for collection. When the syringe is filled with liquid, if the force of extraction is large, some air may enter the needle tube of the syringe. Some of the air in the liquid initially discharged from the syringe can generate bubbles that can be received by the collecting box 105. As the lifting frame 103 continues to move upward, the collecting box 105 gradually leaves the bottom of the syringe, and the liquid is no longer received by the collecting box 105 and can flow to the test tube or glass slide placed on the base 100. The amount of liquid discharged from the syringe after the collecting box 105 leaves the bottom of the syringe can be controlled by controlling the distance of the lifting frame 103 to move upward by the lifting component, so as to adapt to the drip loading of different containers and carriers. When the operator uses the syringe to extract the liquid, different forces The piston shaft moves at different distances. The present application utilizes the positioning piece 102 to fix the piston shaft and allows the lifting frame 103 to move the syringe, which can ensure that the movement distances of multiple syringes placed on the lifting frame 103 are consistent, so that the amount of liquid discharged by the multiple syringes is the same. The piston shafts on the multiple syringes are not long or short, which will cause the amount of liquid carried on each test tube or glass slide to be different, thereby affecting the subsequent testing of uric acid. The problem that the technicians in the prior art need to manually drop the extracted liquid on the glass slide or pour it into the test tube, and the amount is not easy to control. If the amount is difficult to control in a single sampling, multiple sampling and testing are required, and the process is cumbersome and time-consuming.

[0048] As a further solution of the present invention, the lifting component includes a first rod 200 connected to the base 100. The bottom of the lifting frame 103 is connected with a second rod 201 slidably connected to the first rod 200. A limiting piece 202 is connected to the second rod 201. A lead screw 203 is provided on the base 100. A sliding frame 204 threadedly connected to the lead screw 203 and slidably connected to the second rod 201 is provided on the lead screw 203.

[0049] By providing the lead screw 203, during application, an operator can rotate the lead screw 203. The rotation of the lead screw 203 can move the position of the sliding frame 204 upward through the acting force of the thread. After the sliding frame 204 reaches the position of the limiting piece 202, the second rod 201 can be moved through the limiting piece 202 to achieve the purpose of moving the lifting frame 103 upward.

[0050] As a further solution of the present invention, a first spring 205 is connected between the first rod 200 and the second rod 201.

[0051] By providing the first spring 205, it is convenient to reset the lifting frame 103 subsequently.

[0052] As a further solution of the present invention, a first gear 300 is connected to the lead screw 203. A screw tube 301 is rotatably connected to the fixed frame 101. A screw rod 302 threadedly connected to the screw tube 301 and slidably connected to the fixed frame 101 is provided in the screw tube 301. A positioning piece 102 is connected to the screw rod 302. A second gear 303 meshing with the first gear 300 is connected to the screw tube 301. A preset distance is provided between the sliding frame 204 and the limiting piece 202.

[0053] By providing the first gear 300, when the lead screw 203 rotates to move the sliding frame 204, the sliding frame 204 slides on the second rod 201. The rotation of the lead screw 203 can make the first gear 300 rotate and make the screw tube 301 rotate through the second gear 303. The rotation of the screw tube 301 can make the screw rod 302 slide through the acting force of the thread, so as to achieve the purpose of moving the positioning piece 102 towards the piston shaft and abutting against the piston shaft. By setting a certain distance between the sliding frame 204 and the limiting piece 202, when the lead screw 203 rotates and the first gear 300 rotates, the sliding frame 204 can slide on the second rod 201 without driving the second rod 201 to move until the sliding frame 204 contacts the limiting piece 202, which can provide a certain time for the displacement of the positioning piece 102.

[0054] As a further solution of the present invention, a connection ring 304 is connected to the outside of the solenoid 301. The connection ring 304 is rotatably connected to the inside of the second gear 303. A plurality of card slots 305 are provided on the inner side wall of the second gear 303. A plurality of connection slots 306 are provided on the outer side wall of the connection ring 304. A top contact rod 307 adapted to the card slot 305 is slidably sleeved in the connection slot 306. One end of the top contact rod 307 in the card slot 305 is semi-spherical. A second spring 308 is connected between the top contact rod 307 and the connection slot 306;

[0055] By providing the connection ring 304, the force of the spring can be used to sleeve the top contact rod 307 with the card slot 305. When the second gear 303 rotates, the friction between the top contact rod 307 and the card slot 305 can be used to rotate the connection ring 304, so as to achieve the purpose of rotating the solenoid 301 to move the screw rod 302. After the top contact piece contacts the piston shaft, the movement of the screw rod 302 is restricted. When the lead screw 203 continues to rotate to move the lifting frame 103, the top contact rod 307 contracts into the connection slot 306 under the force of the card slot 305, that is, the second gear 303 idles outside the solenoid 301 to avoid the problem of movement conflict.

[0056] As a further solution of the present invention, the collection component includes a collection box 400 provided on the base 100. A first pipe 401 is connected to the collection box 400. A second pipe 402 is slidably connected to the first pipe 401. The second pipe 402 is communicated with the collection box 105;

[0057] By providing the second pipe 402, when the liquid enters the collection box 105, the liquid can flow into the collection box 400 through the second pipe 402 and the first pipe 401, and the collection box 400 centrally collects the liquid.

[0058] As a further solution of the present invention, the collection component further includes a rotating frame 403 connected to the lead screw 203. A connecting rod 404 is rotatably connected to the rotating frame 403. The other end of the connecting rod 404 is connected to the collection box 105;

[0059] By providing the rotating frame 403, the position of the collection box 105 can be restricted by the second pipe 402 and the first pipe 401. When the rotating frame 403 rotates with the lead screw 203, the position of the collection box 105 can be touched by the connecting rod 404 to move the collection box 105. When the rotating frame 403 rotates with the lead screw 203 by a first preset angle, the collection box 105 moves to the limit position. When the rotating frame 403 continues to rotate, the collection box 105 still wants to return to its original position. In this way, the collection box 105 can receive the liquid initially discharged from the syringe and can leave the bottom of the syringe in time, so that the container or slide can receive the subsequent liquid.

[0060] As a further solution of the present invention, a box body 500 is connected to the top of the base 100. The lead screw 203 is rotatably connected to the box body 500. A motor 501 is provided in the box body 500, and the drive shaft of the motor 501 is connected to the lead screw 203;

[0061] By providing the motor 501, during application, the rotation of the drive shaft of the motor 501 can be used to rotate the lead screw 203, so as to provide a driving force for the rotation of the lead screw 203.

[0062] As a further solution of the present invention, a test tube rack 502 is connected to the top of the base 100;

[0063] By providing the test tube rack 502, it is convenient for the operator to fix the test tube for receiving the liquid in the syringe needle at the top of the base 100, corresponding to the position of the syringe needle tube.

[0064] As a further solution of the present invention, a glass slide rack 503 is connected to the top of the test tube rack 502, and a top opening 504 is provided at the top of the glass slide rack 503;

[0065] By providing the glass slide rack 503, it is convenient for the operator to fix the glass slide for receiving the liquid in the syringe needle at the top of the base 100. When placing the test tube, it can be placed in the test tube rack 502 through the top opening 504 to adapt to the shapes of the glass slide and the test tube.

[0066] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
