Description

Technical Field

[0001] The invention belongs to the technical field of medical test tube disinfection, and in particular relates to a test tube cleaning and disinfecting device for medical experiments and a use method thereof. Background Art

[0002] At present, in the process of medical experiments, test tubes are often used to meet the experimental requirements, so it is very important to keep the test tubes clean. After the experimental analysis, the test tubes need to be uniformly disinfected and cleaned. The previous cleaning method is to use manual cleaning, generally first fill water into the test tube, and then use shaking or cleaning brushes to clean the inside of the test tubes one by one, and then use special equipment to disinfect and store them.

[0003] However, due to the different goals of medical experiments, there may be some contamination in the test tubes. Manual cleaning will not only cause harm to the staff, but also affect the cleaning and disinfection effect. In addition, there may be lumps in the test tubes that stick to the inner wall of the test tubes, and it may not be cleaned up simply by injecting water into the test tubes, which will affect the reuse of the test tubes and bring unnecessary trouble to the users.

[0007] In one or more embodiments of the present invention, a shielding ring plate is fixed on the supporting water tank to block the cleaning and disinfecting water so that the cleaning and disinfecting water is not easy to flow outward, thereby facilitating collection and cleaning and reducing the cleaning pressure of the user. A drainage plate is installed on the shielding ring plate to discharge the used cleaning and disinfecting water to the outside, thereby facilitating the collection by the user and then centralized treatment to avoid secondary contamination.

[0008] In one or more embodiments of the present invention, a lower pressure ring plate is sleeved on the support column rod for supporting the test tube, so as to facilitate the washing of the inner wall of the test tube. A displacement sensor is arranged in the lower pressure ring plate for detecting the descending distance of the lower pressure ring plate. When the descending distance of the lower pressure ring plate reaches a set value, the displacement sensor will send a signal to start the driving motor, thereby washing the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the test tube; A pair of connecting cross bars are fixedly connected between the lower pressure ring plate and the lifting transmission tube, which are used to drive the lifting transmission tube to descend, so that when the test tube pushes the lower pressure ring plate downward, the lifting transmission tube can be driven to move downward, thereby exposing multiple connecting holes, which facilitates the entry of cleaning and disinfection water into the lifting transmission tube; The lower pressure ring plate is provided with a plurality of lower leakage holes for allowing the cleaning and disinfecting water to flow downward, thereby preventing the cleaning and disinfecting water from accumulating in the test tube. Furthermore, due to the continuous flow of the cleaning and disinfecting water, the cleaning and disinfecting water can also act as a lubricant, so that the rotation of the lower pressure ring plate will not affect the test tube.

[0009] In one or more embodiments of the present invention, a pair of supporting protrusions are fixed on the shrinking frame, and a fixed bearing is connected between the end of the fixed bent rod away from the supporting column and the supporting protrusion, which is used to fix the shrinking frame and enable the shrinking frame to rotate, thereby adjusting the angle of the shrinking frame so that the multiple brushes can contact the inner wall of the test tube; One end of the rotating rod disposed in the retracting frame is fixedly connected to a supporting slider for supporting and driving the multiple brushes to move. A supporting spring is connected between the supporting slider and the retracting frame for pulling the supporting slider back to its position, thereby enabling the multiple brushes to move into the retracting frame, thereby reducing the probability of dust falling on the retracting frame or being contaminated.

[0010] In one or more embodiments of the present invention, a plurality of brushes are fixed to one end of the support slider away from the rotating rod for contacting the inner wall of the test tube, and then the rotation of the plurality of brushes is driven by the contraction frame, so that the brushes can scrub the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the inner wall of the test tube.

[0011] In one or more embodiments of the present invention, a buffer groove is drilled on the lifting transmission pipe to provide space for the lifting and moving of the lifting transmission pipe, and an upper sliding pushing block and a lower fixed pushing block are arranged in the buffer groove. The upper sliding pushing block is fixedly connected to the lifting transmission pipe, so that the lifting transmission pipe can drive the upper sliding pushing block to move up and down, thereby squeezing the reset spring, and the lower fixed pushing block is fixedly connected to the supporting column rod, so that the lower fixed pushing block will not move, thereby realizing the compression of the reset spring and providing power for the reset of the lifting transmission pipe; A reset spring is fixedly connected between the upper sliding pushing block and the lower fixed pushing block. The reset spring generates a rebound force through the downward squeezing of the upper sliding pushing block, so that the lifting and transferring tube can be pushed and reset after the test tube is cleaned, so that it is convenient to use again.

[0012] In one or more embodiments of the present invention, a plurality of connecting holes are drilled at the bottom of the lifting transmission tube to facilitate the flow of cleaning and disinfecting water into the lifting transmission tube, so that the cleaning and disinfecting water can be sprayed onto the inner wall of the test tube to achieve cleaning and disinfection of the inner wall of the test tube. Sealing sleeves are connected between the two ends of the lifting transmission tube and the supporting column rod to avoid leakage, so that when the lifting transmission tube does not move downward, the cleaning and disinfecting water will not enter the lifting transmission tube, and the first one-way valve will not spray cleaning and disinfecting water outward. A pair of the sealing sleeves are fixed on the supporting column rod to prevent the sealing sleeves from moving, thereby not reducing the sealing performance of the device. A first sealed bearing is fixedly connected between the support column and the support water tank, so that the rotation of the support column will not be affected by the support water tank, thereby improving the stability of the device.

[0013] In one or more embodiments of the present invention, a puncture cone is provided in the mixing chamber for puncturing the seal on the solution bottle so that the solution in the solution bottle can flow into the mixing chamber to facilitate the mixing of the solutions. A plurality of fixed thin rods are fixedly connected between the puncture cone and the support block for fixing the puncture cone to prevent the puncture cone from moving or falling off. A solution bottle is provided above the puncture cone to contain the disinfection solution, so as to facilitate pouring the solution into the mixing liquid chamber. The solution bottle is threadedly connected to the supporting water tank, so that the cleaning water is not easy to leak when the solution is mixed, the sealing is improved, and the disassembly and installation of the staff are also convenient; In addition, when the solution bottle is not installed, a sealing plug will be provided on the supporting water tank to block the upper port of the mixing chamber, thereby preventing leakage of the cleaning and disinfecting water.

[0014] In one or more embodiments of the present invention, a branch delivery pipe is provided on the support block for delivering cleaning water to the liquid mixing chamber, so as to facilitate mixing of the disinfection solution, the other end of the branch delivery pipe is connected to the water delivery pipe, and a control valve is fixed on the branch delivery pipe for controlling the rotation of the rotating plate so that the rotating plate can be controlled to form a blocking and opening effect; A control rotating plate is provided in the control valve for blocking the control valve so that cleaning water cannot enter the mixing liquid chamber. A control handle is installed on the control rotating plate for driving the rotation of the control rotating plate to facilitate the control of the staff so that cleaning water can flow into the mixing liquid chamber.

[0015] A method for using a test tube cleaning and disinfecting device for medical experiments comprises the following steps: S1. The user inserts the medical experimental test tube upside down into the support column, and then presses the mouth of the test tube on the lower pressure ring plate, and then pushes the test tube downward, so that the test tube pushes the lower pressure ring plate downward, and drives the lifting transmission tube to move downward through the lower pressure ring plate and the connecting cross bar, and the lower pressure ring plate can also detect the lifting and moving distance of the lower pressure ring plate through the displacement sensor when moving; S2. During the descent process, the lifting transmission pipe gradually exposes a plurality of connecting holes, and then the cleaning water in the supporting water tank is transported into the lifting transmission pipe through the connecting holes, and finally ejected through the first one-way valve installed on the top of the lifting transmission pipe, and then can be ejected into the inside of the test tube to achieve the effect of cleaning and disinfection. The cleaning water flows downward along the inner wall of the test tube, then flows to the lower pressure ring plate, and then flows downward through the lower leakage hole. Through multiple buffers, the cleaning water will not splash, avoiding harm to the user. Finally, the cleaning water will be discharged through the drain plate; S3. When the lifting transmission tube moves downward, it will also drive the rotating rod to rotate, and the rotating rod will gradually shrink into the shrinking frame when rotating, so as to push the supporting slider to move outward, and the supporting slider will drive multiple brushes to extend outward, so that the brushes will contact the inner wall of the test tube; S4, when the retracting frame rotates to the horizontal position, the multiple brushes reach the maximum extension distance, and the lower pressure ring plate is also lowered to the lowest position, and then the drive motor is started through the displacement sensor, so that the drive motor drives the rotation of the transmission support shaft and the drive gear, and the drive gear drives the rotation of the support column through the driven gear, so that the multiple brushes can rotate, and the inner wall of the test tube is scrubbed, thereby improving the cleaning and disinfection effect of the test tube; S5. When the test tube cleaning requires the addition of a designated solution for thorough cleaning and disinfection, the staff puts the designated solution into the solution bottle, seals the solution bottle, and then screws the solution bottle onto the supporting water tank. The seal on the solution bottle can be pierced by the piercing cone, so that the solution can flow into the mixed liquid chamber. Then, the control handle is turned to drive the rotation of the control turn plate, so that the cleaning and disinfection water delivered by the water delivery pipe can flow into the mixed liquid chamber through the branch delivery pipe. S6. However, due to the obstruction of the guide arc plate, the cleaning and disinfecting water delivered by the branch delivery pipe can impact downward on the solution, achieve rapid mixing of the solution, improve the mixing effect, and rinse the solution bottle to reduce the waste of the solution. Finally, it is sprayed into the supporting water tank through the second one-way valve, and then impacted on the inner wall of the test tube through the delivery of the lifting transmission pipe and the injection of the first one-way valve, so as to improve the cleaning and disinfection effect of the test tube.

[0016] Compared with the prior art, the present invention improves the cleaning effect of medical experimental test tubes by setting up corresponding mechanisms, prevents operators from being harmed, and can effectively remove lumps adhering to the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the test tube and reducing unnecessary trouble for users.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] like Figure 1-Figure 11 As shown, a test tube cleaning and disinfecting device for medical experiments in one embodiment of the present invention includes: a supporting water tank 1, a disinfection and washing mechanism 2, a driving mechanism 3 and a liquid mixing mechanism 4.

[0022] like Figure 1 As shown, a water delivery pipe 408 is fixedly connected to the support water tank 1, which is used to deliver cleaning water into the support water tank 1, so as to facilitate flushing the inner wall of the test tube. By continuously supplying cleaning water into the support water tank 1, a certain water pressure is generated in the support water tank 1. After the lifting transmission pipe 202 descends, the cleaning and disinfecting water can flow from the connecting hole 218 into the lifting transmission pipe 202, and finally spray out through the first one-way valve 203. A shielding ring plate 101 is fixed on the support water tank 1, which is used to block the cleaning and disinfecting water, so that the cleaning and disinfecting water is not easy to flow outward, thereby facilitating collection and cleaning, and reducing the cleaning pressure of the user. A drainage plate 102 is installed on the shielding ring plate 101, which is used to discharge the used cleaning and disinfecting water to the outside, so as to facilitate the collection by the user, and then centralized treatment, to avoid secondary pollution.

[0023] like Figure 1-Figure 5 As shown, the disinfection and washing mechanism 2 is installed on the supporting water tank 1, and the disinfection and washing mechanism 2 includes a supporting column 201, which is used to support the lifting transmission tube 202 and drive the lifting transmission tube 202 to rotate, and plays a supporting and transmission role. The lifting transmission tube 202 is inserted into the supporting column 201, which is used to transport cleaning water and drive multiple brushes 214 to rotate, so as to clean the inner wall of the test tube. A first one-way valve 203 is installed on the top of the lifting transmission tube 202, which is used to spray cleaning and disinfection water outward, so as to clean the inner wall of the test tube.

[0024] like Figure 1-Figure 6 As shown, a plurality of retractable frames 204 are provided on one side of the support column 201, which are used to provide space for the retraction of the rotating rod 206, so that the rotating rod 206 and the retractable frame 204 can be rotated to adjust the positions of the plurality of brushes 214. A pair of fixed curved rods 205 are fixedly connected between the retractable frame 204 and the support column 201, which are used to support the retractable frame 204 and prevent the retractable frame 204 from falling off. A rotating rod 206 is inserted into the retractable frame 204, which is used to drive the retractable frame 204 to rotate.

[0025] Among them, multiple support frames are fixed on the lifting transmission tube 202, and one end of the rotating rod 206 is rotatably connected to the support frame, so that the rotating rod 206 can rotate when the lifting transmission tube 202 descends, so as to facilitate pushing the brush 214 out to contact the inner wall of the test tube.

[0026] like Figure 1-Figure 4As shown, a lower pressure ring plate 207 is sleeved on the support column 201 to support the test tube, so as to facilitate the washing of the inner wall of the test tube. A displacement sensor is arranged inside the lower pressure ring plate 207 to detect the descending distance of the lower pressure ring plate 207. When the descending distance of the lower pressure ring plate 207 reaches a set value, the displacement sensor will send a signal to start the driving motor 301, thereby washing the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the test tube.

[0027] like Figure 1-Figure 4 As shown, a pair of connecting cross bars 208 are fixedly connected between the lower pressure ring plate 207 and the lifting transmission tube 202, which are used to drive the lifting transmission tube 202 to descend, so that the test tube can drive the lifting transmission tube 202 to move downward when the lower pressure ring plate 207 is pushed downward, thereby exposing multiple connecting holes 218, which facilitates the entry of cleaning and disinfecting water into the lifting transmission tube 202. Multiple lower leakage holes 209 are drilled on the lower pressure ring plate 207, which are used to allow the cleaning and disinfecting water to flow downward, thereby preventing the cleaning and disinfecting water from accumulating in the test tube, and because the cleaning and disinfecting water continues to flow, and the cleaning and disinfecting water can also play a lubricating role, so that the rotation of the lower pressure ring plate 207 will not affect the test tube.

[0028] In addition, a pair of supporting protrusions 210 are fixed on the retraction frame 204, and a fixed bearing 211 is connected between the end of the fixed bent rod 205 away from the supporting column rod 201 and the supporting protrusion 210, which is used to fix the retraction frame 204 and enable the retraction frame 204 to rotate, thereby adjusting the angle of the retraction frame 204 so that multiple brushes 214 can contact the inner wall of the test tube.

[0029] like Figure 1-Figure 6 As shown, one end of the rotating rod 206 disposed in the retracting frame 204 is fixedly connected to a support slider 212 for supporting and driving the multiple brushes 214 to move. A support spring 213 is connected between the support slider 212 and the retracting frame 204 for pulling the support slider 212 back to its original position, thereby enabling the multiple brushes 214 to move into the retracting frame 204, thereby reducing the probability of dust falling on the retracting frame 204 or being contaminated.

[0030] Specifically, a plurality of brushes 214 are fixed to one end of the support slider 212 away from the rotating rod 206 for contacting the inner wall of the test tube, and then the rotation of the plurality of brushes 214 is driven by the contraction frame 204, so that the brushes 214 can scrub the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the inner wall of the test tube.

[0031] like Figure 7As shown, a buffer groove is excavated on the lifting transmission tube 202 to provide space for the lifting and moving of the lifting transmission tube 202, and an upper sliding pushing block 215 and a lower fixed pushing block 216 are arranged in the buffer groove. The upper sliding pushing block 215 is fixedly connected to the lifting transmission tube 202, so that the lifting transmission tube 202 can drive the upper sliding pushing block 215 to move up and down, thereby squeezing the reset spring 217, and the lower fixed pushing block 216 is fixedly connected to the support column 201, so that the lower fixed pushing block 216 will not move, thereby realizing the compression of the reset spring 217, and providing power for the reset of the lifting transmission tube 202.

[0032] Specifically, a reset spring 217 is fixedly connected between the upper sliding pushing block 215 and the lower fixed pushing block 216. The upper sliding pushing block 215 is pressed downward to make the reset spring 217 generate a rebound force, so that the lifting and transferring tube 202 can be pushed and reset after the test tube is cleaned, so that it is convenient to use again.

[0033] like Figure 1-Figure 9 As shown, the bottom of the lifting transmission tube 202 is provided with a plurality of connecting holes 218, which are used to facilitate the flow of cleaning and disinfecting water into the lifting transmission tube 202, so that the cleaning and disinfecting water can be sprayed onto the inner wall of the test tube to achieve cleaning and disinfection of the inner wall of the test tube. Sealing sleeves 219 are connected between the two ends of the lifting transmission tube 202 and the supporting column 201 to prevent leakage, so that when the lifting transmission tube 202 does not move downward, cleaning and disinfecting water will not enter the lifting transmission tube 202, and the first one-way valve 203 will not spray cleaning and disinfecting water outward. A pair of sealing sleeves 219 are fixed on the supporting column 201 to prevent the sealing sleeves 219 from moving, so as not to reduce the sealing performance of the device.

[0034] In addition, a first sealed bearing 220 is fixedly connected between the support column 201 and the support water tank 1, so that the rotation of the support column 201 will not be affected by the support water tank 1, thereby improving the stability of the device.

[0035] like Figure 1-Figure 8As shown, the driving mechanism 3 is installed in the supporting water tank 1, and the driving mechanism 3 is used to drive the rotation of the supporting column 201 and the lifting transmission tube 202, so as to drive the rotation of multiple contraction frames 204 and the rotating plug rod 206 through the supporting column 201, thereby improving the cleaning effect of the test tube. The driving mechanism 3 includes a driving motor 301, which provides power for the rotation of the supporting column 201. A protective cover 302 is installed outside the driving motor 301, which plays a supporting and transmission role, and a transmission support shaft 303 is fixedly connected to the driving motor 301. A driving gear 304 is fixed to the other end of the transmission support shaft 303, and a driven gear 305 is meshed on the driving gear 304. The driven gear 305 is fixed on the supporting column 201, and a second sealed bearing 306 is fixedly connected between the transmission support shaft 303 and the supporting water tank 1.

[0036] like Figure 1-Figure 10 As shown, the liquid mixing mechanism 4 is installed on one side of the support column 201, and the liquid mixing mechanism 4 includes a support block 401, and the support block 401 is excavated with a liquid mixing chamber 402 to provide space for mixing disinfection solution and cleaning water. A guide arc plate 403 is installed on the side wall of the liquid mixing chamber 402 to block the cleaning water so that the cleaning water can rush into the solution in the liquid mixing chamber 402, thereby improving the mixing effect of the solution and the cleaning water. A plurality of second one-way valves 404 are installed on the support block 401 to spray out the mixed cleaning and disinfection water and have the function of preventing backflow.

[0037] like Figure 1-Figure 10 As shown, a puncture cone 405 is provided in the mixing chamber 402 for puncturing the seal on the solution bottle 407, so that the solution in the solution bottle 407 can flow into the mixing chamber 402, which is convenient for mixing the solutions. A plurality of fixed thin rods 406 are fixedly connected between the puncture cone 405 and the support block 401, which are used to fix the puncture cone 405 to prevent the puncture cone 405 from moving or falling off. The cleaning and disinfecting water will first impact the disinfecting solution due to the obstruction of the guide arc plate 403, and then after the mixing chamber 402 is filled, the cleaning and disinfecting water will enter the solution bottle 407 again, and will not be sprayed out from the second one-way valve 404 until the solution bottle 407 is also filled, thereby achieving the effect of flushing the solution bottle 407.

[0038] A solution bottle 407 is provided above the puncturing cone 405 to contain the disinfection solution, so as to facilitate pouring the solution into the liquid mixing chamber 402. The solution bottle 407 is threadedly connected to the supporting water tank 1, so that the cleaning water is not easily leaked when the solution is mixed, the sealing is improved, and the disassembly and installation of the staff are convenient. In addition, when the solution bottle 407 is not installed, a sealing plug is provided on the supporting water tank 1 to block the upper port of the liquid mixing chamber 402, thereby preventing leakage of the cleaning and disinfection water.

[0039] like Figure 1-Figure 11As shown, a branch delivery pipe 409 is provided on the support block 401 for delivering cleaning water to the liquid mixing chamber 402, so as to facilitate mixing of the disinfection solution, and the other end of the branch delivery pipe 409 is connected to the water delivery pipe 408. A control valve 410 is fixed on the branch delivery pipe 409 for controlling the rotation of the rotating plate 411 so that the rotating plate 411 can form a blocking and opening effect.

[0040] In addition, a control rotating plate 411 is provided in the control valve 410 for blocking the control valve 410 so that the cleaning water cannot enter the mixing liquid chamber 402. A control handle 412 is installed on the control rotating plate 411 for driving the rotation of the control rotating plate 411 to facilitate the control of the staff so that the cleaning water can flow into the mixing liquid chamber 402.

[0041] A method for using a test tube cleaning and disinfecting device for medical experiments comprises the following steps: S1. The user inserts the medical experimental test tube upside down into the support column 201, and then presses the mouth of the test tube on the lower pressure ring plate 207, and then pushes the test tube downward, so that the test tube pushes the lower pressure ring plate 207 downward, and drives the lifting transmission tube 202 to move downward through the lower pressure ring plate 207 and the connecting cross bar 208, and the lower pressure ring plate 207 can also detect the lifting and moving distance of the lower pressure ring plate 207 through the displacement sensor when moving; S2. During the descent process of the lifting transmission pipe 202, a plurality of connecting holes 218 are gradually exposed, and then the cleaning water in the supporting water tank 1 is transported into the lifting transmission pipe 202 through the connecting holes 218, and finally ejected through the first one-way valve 203 installed on the top of the lifting transmission pipe 202, and then can be ejected into the inside of the test tube to achieve the effect of cleaning and disinfection, and the cleaning water will flow downward along the inner wall of the test tube, and then flow to the lower pressure ring plate 207, and then flow downward through the lower leakage hole 209. Through multiple buffers, the cleaning water will not splash, avoiding harm to the user, and finally the cleaning water will be discharged through the drainage plate 102; S3. When the lifting transmission tube 202 moves downward, it also drives the rotating rod 206 to rotate, and the rotating rod 206 gradually shrinks into the shrinking frame 204 during the rotation, so as to push the supporting slider 212 to move outward, and the supporting slider 212 drives the plurality of brushes 214 to extend outward, so that the brushes 214 contact the inner wall of the test tube; S4, when the retracting frame 204 rotates to the horizontal position, the multiple brushes 214 reach the maximum extension distance, and the lower pressure ring plate 207 is also lowered to the lowest position, and the drive motor 301 is started through the displacement sensor, so that the drive motor 301 drives the rotation of the transmission support shaft 303 and the drive gear 304, and the drive gear 304 drives the rotation of the support column 201 through the driven gear 305, so that the multiple brushes 214 can rotate, and the inner wall of the test tube is scrubbed, thereby improving the cleaning and disinfection effect of the test tube; S5. When the test tube cleaning needs to add a designated solution to ensure thorough cleaning and disinfection, the staff puts the designated solution into the solution bottle 407, then seals the solution bottle 407, and then screws the solution bottle 407 onto the supporting water tank 1. The piercing cone 405 can pierce the seal on the solution bottle 407, so that the solution can flow into the mixing liquid chamber 402, and then the control handle 412 is turned to drive the rotation of the control rotating plate 411, so that the cleaning and disinfecting water delivered by the delivery pipe 408 can flow into the mixing liquid chamber 402 through the branch delivery pipe 409; S6. However, due to the obstruction of the guide arc plate 403, the cleaning and disinfecting water delivered by the branch delivery pipe 409 can impact downward on the solution, thereby achieving rapid mixing of the solution and improving the mixing effect. It can also rinse the solution bottle 407 and reduce the waste of the solution. Finally, it is sprayed into the supporting water tank 1 through the second one-way valve 404, and then impacted on the inner wall of the test tube through the delivery of the lifting transmission pipe 202 and the injection of the first one-way valve 203, so as to improve the cleaning and disinfection effect on the test tube.
