Description

Technical Field

[0001] This invention relates to the field of blood collection machine technology, and more specifically, to a blood collection device with a shielding effect for patients who faint at the sight of blood. Background Technology

[0002] A blood-drawing machine is a machine designed using infrared and ultrasound imaging technology. It is specifically used to replace nurses in giving injections and drawing blood from patients. This machine is faster and more accurate than manual blood drawing, thus improving the efficiency of blood collection.

[0003] In the prior art, Chinese patent with authorization announcement number CN106510730B discloses a vein depth measuring device and a blood collection machine. The device calculates the depth data of the target subcutaneous vein by processing the foreground extraction image. The correction module is used to receive the depth data and process the depth data to calculate the accurate depth data of the target subcutaneous vein. Calculating the vein depth using image processing technology can make the puncture work more efficient and improve the puncture accuracy.

[0004] However, in actual blood collection operations, although existing technologies have made blood collection more efficient, mechanical blood collection methods can increase the fear of those being drawn, and for some patients who faint at the sight of blood, this environment increases the risk of fainting, which is somewhat dangerous. When conducting large-scale blood collection, it is necessary to frequently change the blood collection tubes, and manual connection and replacement will increase the blood collection time and affect the efficiency of blood collection. Summary of the Invention

A snap-fit ​​sleeve is connected to the bottom end of the three-way valve, and multiple sets of blood test tubes are inserted into the blood storage chamber.

[0012] Optionally, the top of the blood test tube is connected to a connecting tube, and the connecting tube is fitted with a snap-fit ​​sleeve. The three-way valve is provided with a three-way ball valve core. One end of the three-way ball valve core is connected to a valve shaft. One end of the valve shaft passes through a lifting connecting plate and is connected to a valve drive gear. A fixed gear plate is connected between the lifting connecting plate and the main body of the collector, and the valve drive gear meshes with the fixed gear plate.

[0013] Optionally, an electric lifting cylinder is provided between the lifting connecting plate and the peristaltic blood pump, and the top of the output shaft of the electric lifting cylinder is connected to the lifting connecting plate. One end of the lifting connecting plate is sleeved on the outside of the three-way valve, and the end of the lifting connecting plate away from the three-way valve is connected to a transmission gearbox. The top of the transmission gearbox is connected to a transmission gear set.

[0014] Optionally, the transmission gear set includes a lifting connecting gear and a transmission bevel gear, and the lifting connecting gear and the transmission bevel gear are connected by a rotating shaft.

[0016] Optionally, a waste liquid tank and a disinfection patch are connected to the top of the connecting base plate, and multiple sets of limiting gears are connected inside the connecting base plate via a rotating shaft. A sliding gear plate is connected to the bottom of the blood storage chamber. Both sides of the sliding gear plate have toothed structures. The moving drive gear and multiple sets of limiting gears are distributed on both sides of the sliding gear plate, and the sliding gear plate meshes with the moving drive gear and the multiple sets of limiting gears.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above solution, a display screen with a screen to block out obstructions and distract attention is used to prevent patients from fainting at the sight of blood. An observation window is provided on one side for the accompanying person to observe and prevent accidents. The front of the main unit of the blood collection device is made of opaque plastic or metal to prevent the user from seeing the blood collection process inside, which could cause fainting.

The observation window allows doctors, nurses, or accompanying persons to observe the blood collection process from the side to prevent accidents.

[0019] By incorporating automatic tube switching and disinfection equipment, blood collection efficiency is increased and manpower consumption is reduced. A peristaltic blood pump, driven by a blood pump motor, reverses direction. During this process, disinfectant solution from the cleaning and disinfection chamber is delivered through a rinsing hose and a three-way valve into the blood collection hose. The collection needle assembly and its connecting block are then disinfected. Waste liquid from the collection needle assembly is discharged into a waste tank, where it is further disinfected by a disinfection dressing device. Upon completion of one cleaning cycle, the blood tubes in the blood storage chamber are moved to a new position and lowered via an electric lifting cylinder, completing the tube switching and the transition to the next blood collection procedure.

[0020] The linkage-driven structure ensures that blood collection and disinfection work do not interfere with each other, guaranteeing the purity of the collected blood and the continuity of the work. The electric lifting cylinder drives the lifting plate to move up and down. During the movement of the lifting plate, the three-way valve, the lifting plate connected to it, the transmission gearbox, and the transmission gear set connected to it all move up and down together. During the movement of the lifting plate, the valve drive gear rotates through the fixed gear plate. During the rotation of the valve drive gear, the valve shaft drives the three-way ball valve core to rotate, thereby switching the passage and completing the switching between blood collection and cleaning. The lifting plate also connects or disconnects the blood tube from the three-way valve during the lifting process. Attached Figure Description

[0055] like Figures 1 to 9 As shown, this embodiment of the invention provides a blood collector with a shielding effect for patients who faint at the sight of blood. It includes a collector main body 1, a collection component 3, and a blood storage chamber 8. The front of the collector main body 1 is provided with a display screen 11, and a collection hole 12 is provided below the display screen 11. A base box 2 is provided below the collector main body 1.

[0056] The main body 1 of the collector contains a main unit housing 4, and a movable connecting top plate 41 is located below the main unit housing 4. The collection component 3 slides below the movable connecting top plate 41. A peristaltic blood pump 5, a lifting connecting plate 6, and a cleaning and disinfection box 7 are connected to the inner wall of the main body 1. A connecting bottom plate 21 is connected inside the bottom box 2, and the blood storage chamber 8 is slidably connected above the connecting bottom plate 21. The user can pre-tie a pressure band to make the veins in the arm protrude, which facilitates subsequent identification and positioning work, and then insert the arm into the collection port. Within 12, blood is collected via the collection component 3. The peristaltic blood pump 5 pumps the blood into the blood storage chamber 8. The front of the main body 1 of the collector is made of opaque plastic or metal to prevent the user from seeing the blood collection process inside, which could cause fainting. The display screen 11 can be used to play decompression videos or promotional videos to distract the person being drawn. The main unit 4 contains a motor assembly and control system that drive the entire collection component 3 to move. Precise moving and collecting actions are achieved by using a central control system and a variable frequency motor.

[0057] like Figure 1 and Figure 2As shown, the collection hole 12 is a central hole, and arm pads 121 with a circumference of 2 / 5 are connected to both sides of the bottom of the collection hole 12. A restraint strap 122 is connected to the top of the arm pads 121. An observation window 13 is provided on one side of the main body 1 of the blood collector. A detachable back plate 14 is bolted to the back of the main body 1 of the blood collector, and a blood chamber door 15 is connected to the bottom of the detachable back plate 14 via a pivot. After the blood donor inserts their arm into the collection hole 12, the arm is placed in the arm pad. The blood collection device 121 is mounted on a pad, and a restraint strap 122 can be used to prevent the user's arm from shifting during blood collection. The restraint strap 122 can be secured with an elastic band or Velcro. The observation window 13 allows doctors, nurses, or accompanying persons to observe the blood collection process from the side to prevent accidents. The main body 1 of the blood collection device can be opened through a detachable back panel 14 for easy maintenance. The blood chamber door 15 can be opened and closed manually to facilitate the removal or insertion of the blood storage chamber 8.

[0058] The display screen 11, which is designed to block and distract attention, is used to prevent patients from fainting at the sight of blood. An observation window 13 is provided on one side for the accompanying person to observe and prevent accidents. The front of the main body 1 of the blood collection device is made of opaque plastic or metal to prevent the user from seeing the blood collection process inside, which could lead to fainting. The display screen 11 can be used to play decompression videos or promotional videos to distract the person having their blood drawn. The observation window 13 is for doctors, nurses, or accompanying persons to observe the blood collection process from the side to prevent accidents.

[0059] like Figures 2 to 9 As shown, the acquisition component 3 includes a movable slide plate 31 and an acquisition connecting block 33. A recognition camera component 32 is connected to the side of the movable slide plate 31 closest to the display screen 11. The acquisition connecting block 33 is connected to the bottom of the movable slide plate 31, and a acquisition needle component 34 is connected to the bottom of the acquisition connecting block 33. The recognition camera component 32 is a high-pixel recognition camera and can be equipped with a thermal imaging device to more accurately locate the veins in the arm. The movable slide plate 31 and the movable connecting top plate 41 form a two-axis moving structure, controlling precise movement based on the recognition results. Block 33 is used to connect the delivery tubing and the collection needle assembly 34. The collection needle assembly 34 is an oblique structure within the collection connecting block 33 to facilitate puncture. The collection connecting block 33 is equipped with an oblique moving mechanism that simulates the trajectory of oblique puncture veins during manual blood collection and achieves precise venous puncture through machine drive. This facilitates puncture through the collection needle assembly 34. The collection needle assembly 34 can be a single needle or a puncture and collection structure composed of a needle and a needle tube. The collection and puncture equipment, its specific movement trajectory, and its principle are existing mature technologies.

[0060] like Figure 2 and Figure 4 As shown, the lifting connecting plate 6 is disposed between the peristaltic blood pump 5 and the cleaning and disinfection box 7, and the lifting connecting plate 6 is slidably connected to the inner wall of the collector main body 1. A three-way valve 61 is fixedly connected to the side of the lifting connecting plate 6 away from the collector main body 1, and the peristaltic blood pump 5 is provided with an inverted V-shaped pipeline connection groove 51. The lifting connecting plate 6 can slide and move on the inner wall of the collector main body 1. The peristaltic blood pump 5 is a peristaltic pump, which realizes the unidirectional movement of fluid by squeezing the outside of the pipeline, so as to transport without contact with blood, prevent blood contamination, and prevent blood coagulation by squeezing during transportation. The cleaning and disinfection box 7 contains disinfectant for sterilizing the inside of the collection component 3.

[0061] A blood-drawing tubing 331 is connected between the three-way valve 61 and the collection connection block 33, and the blood-drawing tubing 331 is snapped into the pipeline connection groove 51. A flushing tubing 611 is connected between the three-way valve 61 and the cleaning and disinfection box 7, and a rehydration tube 71 is connected to one side of the cleaning and disinfection box 7. A snap-fit ​​sleeve 612 is connected to the bottom end of the three-way valve 61. Multiple sets of blood test tubes 81 are inserted into the blood storage chamber 8. One end of the blood-drawing tubing 331 is inserted into the collection connection block 33 and is sleeved or inserted into the needle assembly of the collection needle assembly 34. The blood-drawing tubing 331 is fixed in the peristaltic... The blood pump 5 is connected to the pipeline 51, and blood input and disinfectant output are completed within the pipeline 51. The cleaning and disinfection box 7 can be made transparent for easy observation of the liquid level, or a liquid level gauge can be installed for observation. It can also be programmed to issue an alarm when the internal liquid level is too low, so that disinfectant can be replenished in time through the replenishment tube 71. The disinfectant inside the cleaning and disinfection box 7 is sent into the blood drawing tube 331 through the rinsing tube 611 via the three-way valve 61, and then transported through the blood drawing tube 331 to the inside of the collection needle assembly 34 and the collection connection block 33 for disinfection.

[0062] like Figures 4 to 7As shown, the top of the blood test tube 81 is connected to a connecting tube 811, and the connecting tube 811 is fitted with a snap-fit ​​sleeve 612. A three-way ball valve core 62 is installed inside the three-way valve 61. One end of the three-way ball valve core 62 is connected to a valve shaft 621. One end of the valve shaft 621 passes through a lifting connecting plate 6 and is connected to a valve drive gear 622. A fixed gear plate 16 connects the lifting connecting plate 6 and the collector main body 1, and the valve drive gear 622 meshes with the fixed gear plate 16. The three-way ball valve core 62 has a common three-way valve core structure with two through holes on its outer side, one of which is always connected to the blood drawing tubing 331. During the lifting and lowering movement of the lifting connecting plate 6, the valve drive gear 622 is driven to rotate by the fixed gear plate 16, and the valve drive gear 622 rotates during this process. The valve shaft 621 drives the three-way ball valve core 62 to rotate, thereby switching the flow path and completing the switching between blood drawing and cleaning. The blood collected by the collection component 3 is sent into the three-way valve 61 through the blood drawing tube 331, and then into the insertion connecting tube 811 through the snap sleeve 612. The blood then flows into the blood test tube 81 for collection. When the insertion connecting tube 811 is inserted into the snap sleeve 612, its opening is in contact with the outlet of the three-way ball valve core 62 to prevent blood from entering the snap sleeve 612 and causing blood residue and contamination. The insertion connecting tube 811 is made of plastic or silicone and can be equipped with a heat sealing machine to seal the insertion connecting tube 811 through external pressure and heat to ensure the cleanliness of the blood. The blood storage chamber 8 can be equipped with temperature control and shaking devices to ensure the blood storage environment.

[0063] like Figure 4 As shown, an electric lifting cylinder 9 is provided between the lifting connecting plate 6 and the peristaltic blood pump 5, and a lifting plate 91 is connected to the top of the output shaft of the electric lifting cylinder 9. One end of the lifting plate 91 is sleeved on the outside of the three-way valve 61, and the end of the lifting plate 91 away from the three-way valve 61 is connected to a transmission gearbox 92. A transmission gear set 921 is connected to the top of the transmission gearbox 92. The electric lifting cylinder 9 is controlled by a central control program. It is raised after the blood collection work is completed and lowered after the cleaning work is completed. The electric lifting cylinder 9 drives the lifting plate 91 to perform the lifting action. During the movement, the lifting plate 91 drives the three-way valve 61 and the lifting plate 91 connected to it, as well as the transmission gearbox 92 and the transmission gear set 921 connected to it to move up and down together. In order to ensure the stability of its lifting movement, a sliding groove or slider can be added between it and the inner wall of the collector main body 1 to ensure smooth movement.

[0064] like Figure 8As shown, the transmission gear set 921 includes a lifting connecting gear 922 and a transmission bevel gear 923, and the lifting connecting gear 922 and the transmission bevel gear 923 are connected by a rotating shaft. The transmission gear box 92 is connected to a transmission connecting shaft 924, and the two ends of the transmission connecting shaft 924 are respectively connected to a driven bevel gear 925 and a moving drive gear 926.

[0065] A blood pump motor 52 is provided on one side of the peristaltic blood pump 5, and a reduction gearbox 521 is connected to the output shaft of the blood pump motor 52. One end of the output shaft of the reduction gearbox 521 is connected to the peristaltic blood pump 5, and a switching drive gear 522 that meshes with the lifting connecting gear 922 is sleeved on the outside of the output shaft of the reduction gearbox 521. The driven bevel gear 925 and the transmission bevel gear 923 mesh. The peristaltic blood pump 5 is driven by the blood pump motor 52 to pump, and the switching of the peristaltic blood pump 5's pumping and pumping operations can be achieved by the forward and reverse rotation of the blood pump motor 52. When the transmission gear set 921 rises, it completes the meshing of the lifting connecting gear 922 and the switching drive gear 522. The blood pump motor 52 drives the switching drive gear 522 to rotate through the reduction gearbox 521. During the rotation of 22, the transmission gear set 921 and its connected transmission bevel gear 923 are driven to rotate, and the transmission bevel gear 923 drives the driven bevel gear 925 to rotate. In turn, the driven bevel gear 925 drives the moving drive gear 926 to rotate. When the electric lifting cylinder 9 drives the lifting plate 91 to lift, the lifting plate 91 drives the transmission gear set 921 to lift. During the lifting process, the lifting connecting gear 922 and the switching drive gear 522 are engaged, thus completing the connection between the transmission gear set 921 and the blood pump motor 52 drive structure. At this time, the blood pump motor 52 can drive the movement of the blood storage chamber 8, thereby realizing the replacement of the blood tube 81 while switching between blood drawing and cleaning modes.

[0066] By setting up automatic tube switching and automatic disinfection equipment, the efficiency of blood collection is increased and the consumption of manpower is reduced. The peristaltic blood pump 5 is reversed by the blood pump motor 52. At this time, the disinfectant inside the cleaning and disinfection box 7 is sent into the blood collection tube 331 through the rinsing hose 611 and the three-way valve 61. The blood collection tube 331 is then sent into the collection needle assembly 34 and the collection connection block 33 for disinfection. The waste liquid discharged from the collection needle assembly 34 is discharged into the waste liquid tank 22 and disinfected by the disinfection patch device 23. When the equipment completes one cleaning operation, the blood tube 81 in the blood storage chamber 8 completes a position switch. At this time, it can be driven by the electric lifting cylinder 9 to perform a lowering action, completing the switching of the blood tube 81 and the switching of the next blood collection process. That is, when it moves to the next test tube position, the empty blood tube 81 is reconnected to the snap sleeve 612 by the lifting action, and the next blood collection process can be carried out.

[0067] like Figures 2 to 9 As shown, the top of the connecting base plate 21 is connected to a waste liquid tank 22 and a disinfection patch device 23. Multiple sets of limiting gears 211 are connected inside the connecting base plate 21 via a rotating shaft. The bottom of the blood storage chamber 8 is connected to a sliding gear plate 82. Both sides of the sliding gear plate 82 have toothed structures, which mesh with the moving drive gear 926 and the multiple sets of limiting gears 211, respectively. The moving drive gear 926 drives the sliding gear plate 82 to slide, and during this movement, the sliding gear plate 82 drives the multiple sets of limiting gears 211 to rotate. The limiting gears 211 are mainly used to fix the position and sliding direction of the sliding gear plate 82, making the movement of the fixed sliding gear plate 82 more stable. The moving drive gear 926 and the multiple sets of limiting gears 211 are distributed on both sides of the sliding gear plate 82, and the sliding gear plate 82 meshes with the moving drive gear 926 and the multiple sets of limiting gears 211.

[0068] The waste liquid tank 22 is used to collect the waste liquid discharged from the collection needle assembly 34 during rinsing. The disinfection patch device 23 is an alcohol spraying device that can spray disinfection on the blood collection site and disinfect the collection needle assembly 34 during disinfection. It can also be equipped with a device for pressing alcohol swabs. Both the disinfection patch device 23 and the alcohol swab pressing device are conventional equipment in existing blood collection machines. During rotation, the moving drive gear 926 drives the sliding gear plate 82 and the connected blood storage chamber 8 to move. The device completes one... During the next cleaning operation, the blood tubes 81 in the blood storage chamber 8 complete a positional shift. The sliding gear plate 82 uses multiple sets of limit gears 211 to make the movement smoother. When the blood storage chamber 8 moves to the maximum distance, an alarm will sound to remind you to replace the blood tubes 81. When switching to the blood collection process, the blood storage chamber 8 can be freely pulled out. The height of the moving drive gear 926 is greater than the lifting height of the electric lifting cylinder 9, so that the sliding gear plate 82 and the moving drive gear 926 can always be engaged during the lifting process.

[0069] The linkage-driven structure ensures that blood collection and disinfection work do not interfere with each other, guaranteeing the purity of the collected blood and the continuity of the work. The electric lifting cylinder 9 drives the lifting plate 91 to move up and down. During the movement of the lifting plate 91, the three-way valve 61 and the lifting plate 91 connected to it, as well as the transmission gearbox 92 and the transmission gear set 921 connected to it, move up and down together. During the movement of the lifting connecting plate 6, the valve drive gear 622 is driven to rotate through the fixed gear plate 16. During the rotation of the valve drive gear 622, the valve shaft 621 drives the three-way ball valve core 62 to rotate, thereby realizing the switching of the passage and completing the switching of blood collection and cleaning work. During the movement of the lifting connecting plate 6, the blood tube 81 is connected or disconnected from the three-way valve 61.

[0070] The workflow of the technical solution provided by this invention is as follows:

[0071] First, the user puts on a pressure bandage to make the veins on the arm protrude, which facilitates subsequent identification and positioning. Then, the user inserts the arm into the collection port 12. After the user inserts the arm into the collection port 12, the arm is placed on the arm pad 121. The user can also use a restraint strap 122 to prevent the arm from shifting during blood collection. At the same time, the disinfection patch device 23 sprays disinfectant on the blood collection site.

[0072] The identification camera component 32 locates the vein in the arm, and the two-axis moving structure formed by the moving slide plate 31 and the moving connecting top plate 41 controls the precise movement based on the identification results. The collection connecting block 33 drives the collection needle component 34 to perform puncture and blood collection. The blood pump motor 52 drives the peristaltic blood pump 5 to perform pumping action. The blood collected by the collection component 3 is sent into the three-way valve 61 through the blood drawing tube 331, and then into the insertion connecting tube 811 through the snap sleeve 612. Then, it flows into the blood test tube 81 for collection through the insertion connecting tube 811. After collection, the electric lifting cylinder 9 drives the process to switch, and the insertion connecting tube 811 is separated from the three-way valve 61 during the switching process. The insertion connecting tube 811 is then sealed by the heat sealing machine using external pressure and heat.

[0073] The electric lifting cylinder 9 drives the lifting plate 91 to move up and down. During the movement of the lifting plate 91, the three-way valve 61 and the lifting plate 91 connected to it, as well as the transmission gearbox 92 and the transmission gear set 921 connected to it, move up and down together. During the movement of the lifting plate 6, the valve drive gear 622 is driven to rotate through the fixed gear plate 16. During the rotation of the valve drive gear 622, the valve core 62 of the three-way ball valve is driven to rotate through the valve shaft 621, thereby realizing the switching of the passage and completing the switching of blood drawing and cleaning.

[0074] Then, the peristaltic blood pump 5 is reversed by the blood pump motor 52. At this time, the disinfectant inside the cleaning and disinfection box 7 is sent into the blood drawing tube 331 through the rinsing tube 611 and the three-way valve 61. The blood drawing tube 331 is then sent into the inside of the collection needle assembly 34 and the collection connection block 33 for disinfection. The waste liquid discharged from the collection needle assembly 34 is discharged into the waste liquid tank 22, and the collection needle assembly 34 is disinfected by the disinfection patch device 23.

[0075] Simultaneously, the blood pump motor 52 drives the switching drive gear 522 to rotate via the reduction gearbox 521. During the rotation of the switching drive gear 522, the transmission gear set 921 and its connected transmission bevel gear 923 are driven to rotate. The transmission bevel gear 923 drives the driven bevel gear 925 to rotate. During the rotation of the driven bevel gear 925, the moving drive gear 926 is driven to rotate. During the rotation of the moving drive gear 926, the sliding gear plate 82 and its connected blood storage chamber 8 are moved. When the equipment completes one cleaning operation, the blood tube 81 in the blood storage chamber 8 completes a position change. At this time, it can be driven by the electric lifting cylinder 9 to perform a lowering action, completing the switching of the blood tube 81 and the switching of the next blood drawing process. That is, when it moves to the next tube position, the empty blood tube 81 is reconnected to the snap sleeve 612 by the lifting action, and the next blood drawing process can be carried out.

[0076] Furthermore, during the blood draw process, the patient's attention can be diverted by playing decompression videos or promotional videos on the display screen 11. Doctors, nurses, or accompanying persons can observe the blood draw process from the side through the observation window 13 to prevent accidents. When the blood storage chamber 8 moves to its maximum distance, the machine will sound an alarm to remind staff to replace the blood test tube 81. The blood storage chamber 8 can be pulled out or put in by manually opening and closing the blood chamber door 15. When maintenance is required inside, the main body of the collector 1 can be opened through the detachable back panel 14.

[0078] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
