Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic liquid changing device, and in particular to an automatic liquid changing device. BACKGROUND

[0002] Intravenous infusion is a method of using atmospheric pressure and hydrostatic pressure to inject a large amount of sterile liquid, electrolyte and drug into the body through the vein, and injecting a large amount of liquid, electrolyte or blood into the vein is called intravenous infusion method, which can be divided into peripheral intravenous infusion, central intravenous infusion, high-nutrition infusion and blood transfusion according to the injection site and infusion.

[0003] With the development of society, people pay more and more attention to the health of the body, and the requirement for medical level is higher and higher, but due to the limited number of medical staff in the hospital, careful work is required, which causes a contradiction between the medical level and the demand of the people. In order to solve this contradiction, on the basis of the existing medical level, gradually improving the automation level of medical equipment is the trend, and in the current medical process, intravenous infusion is a common treatment method. In intravenous infusion, multiple bottles or bags of medicine need to be input by the patient during infusion, and currently nursing workers need to manually replace each bottle of medicine after inputting, and many times medical staff need to replace the liquid personally, which greatly increases the workload of medical staff, and the patient or family members may delay the call due to negligence, therefore, the present application provides an automatic liquid changing device. SUMMARY

[0006] Furthermore, the rotating device includes a servo motor, a rotating disk, and rotating plates. The servo motor is installed inside the upper end of the retractable frame of the automatic telescopic frame. The rotating disk is installed on the output end of the servo motor. Several rotating plates are provided, and the several rotating plates are evenly arranged around the lower end of the rotating disk.

[0007] Furthermore, the outer side of the rotating disk is uniformly surrounded by a number of placement slots, and the positions of the placement slots correspond one-to-one with the positions of the rotating plates.

[0008] Furthermore, each of the aforementioned storage devices includes a connecting component and a storage component. The connecting component includes a connecting shaft, a connecting disc, a connecting block, and a limiting block. The connecting disc is disposed at the lower end of the rotating plate. The connecting shaft is rotatably connected to the axis of the connecting disc, with both ends located on both sides of the connecting disc. One end of the connecting block is connected to the beginning of the connecting shaft. The connecting disc is provided with a circular groove, and the end of the limiting block is located within the circular groove and is slidably fitted.

[0009] Furthermore, each of the aforementioned storage components includes an upper fixing member, a mesh pocket, and a lower fixing member. The upper fixing member is connected to the first end of the limiting block and is made of rubber. The lower fixing member is connected to the other end of the connecting block. The upper fixing member and the lower fixing member are connected by the mesh pocket. The lower fixing member is ring-shaped and has an inclined groove on it. A limiting shaft can be inserted into the inclined groove.

[0010] Furthermore, the auxiliary flipping device includes helical gears, auxiliary rods, and an auxiliary disk. The auxiliary disk is fitted onto the extendable frame of the automatic telescopic frame. Several helical gears are provided, each set at the end of a corresponding connecting shaft. The auxiliary disk has several helical teeth that mesh with the helical gears. The auxiliary disk also has a circular track. Several auxiliary rods are provided, each set on a corresponding connecting shaft and facing downwards. The lower end of each auxiliary rod has a slider, and the sliders are equidistantly arranged around the circular track and are all slidably engaged.

[0011] Furthermore, the center of the mechanical clamping point is located directly below the axis of the lower fixing component, and the central axis of the conventional infusion puncture needle is located directly below the axis of the lower fixing component after being clamped by the mechanical clamp.

[0012] Furthermore, it also includes a main controller, which controls the operation of the mechanical clamp, liquid sensor, servo motor and automatic telescopic frame. The display screen has an alarm function and is electrically connected to the main controller. The main controller can perform operation design programs through the display screen.

[0013] Furthermore, the storage box has a flexible layer inside, and the interior of the storage box is inclined downwards.

[0014] Furthermore, the helical gear on the connecting shaft of the storage device directly above the infusion puncture needle held by the mechanical clamp is about to contact the matching helical teeth on the auxiliary disk, and the number of helical teeth on the auxiliary disk is enough for the corresponding helical gear to rotate one revolution.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, this device is applicable to various types of infusion products, including plastic infusion bottles, infusion bags, and glass infusion bottles. It can also be used in various lengths and diameters, offering a wide range of applications. Furthermore, after medical staff place the infusion bottles containing the medication in sequence, the device can automatically replace and cycle the infusions to complete the treatment, providing continuous treatment for the patient. This eliminates the need for patients or their families to call for infusion bottle replacements due to negligence. Additionally, it eliminates the need for medical staff to repeatedly change infusion bottles, significantly reducing their workload and effectively improving treatment efficiency and quality.

[0017] Secondly, the entire infusion treatment process of this device is as follows: First, the corresponding medications are placed in the storage box according to their order. → Then, they are placed into the corresponding storage components in the order of infusion. → The infusion needle is clamped and the liquid sensor is clamped onto the infusion tubing. → The infusion needle is inserted into the infusion bottle by the downward movement of the automatic telescopic frame. → When the liquid sensor no longer detects liquid, the initial infusion is completed. → The automatic telescopic frame moves upward, disengaging the infusion needle from the completed infusion bottle. → The servo motor drives the infusion bottle in the next storage component to the infusion position directly above the fixed frame. → The infusion needle is inserted into the required infusion bottle again by the downward movement of the automatic telescopic frame. → The completed infusion bottle is rotated to the top of the storage box and, with the assistance of an auxiliary device, the storage component rotates the completed infusion bottle 180 degrees, causing it to fall down. → The storage component rotates 180 degrees again to return to its original state, preparing for subsequent use. → The treatment begins normally after the liquid sensor detects liquid. → After the treatment is completed through a cyclical automatic replacement operation, the display screen alarms to remind the patient or family to call medical personnel.

[0018] Thirdly, the storage components consist of an upper fixing member, a mesh pocket, and a lower fixing member. Because the infusion bottle is placed inside the mesh pocket with its opening facing downwards, and because the mesh pocket itself is stretchable and can be shaped to fit the desired form using weights, this device is suitable for various types of infusion products, including plastic infusion bottles, infusion bags, and glass infusion bottles, and can be used for different lengths and thicknesses. However, due to the inherent limitations of the mesh pocket itself, it lacks the strength and ability to securely fix the infusion bottle. Therefore, this device… The needle is inserted at an angle and abuts against the ring of the infusion bottle. During the puncture, the upward pressure exerted by the needle on the infusion bottle is transmitted to the limiting shaft. Since the limiting shaft is angled, the pressure is then transmitted to the lower fixing component, which in turn transmits the pressure to the corresponding connecting device. Finally, the pressure is transmitted to the connecting plate via the limiting block, where it is dissipated by the automatic telescopic frame and the ground. The limiting block prevents the corresponding storage components from shaking due to gravity or inertia, thus ensuring the accuracy of the needle insertion.

[0019] Fourth, medical staff can initially connect the computer control system on the workbench to the main controller in this device based on the patient's basic information and medication usage, synchronizing the information on the display screen. Based on this synchronized information, medical staff can accurately place the corresponding infusion bottles in sequence, ensuring the accuracy of the entire treatment. If medication errors occur, the situation can be assessed immediately and appropriate measures taken. After the required infusion bottles are placed in sequence, medical staff can set a specific operating method and process on the display screen. This method involves inputting the number of infusion bottles in sequence. Once the set number is reached, the liquid sensor will not detect any liquid, and the display screen will generate an alarm indicating the end of the infusion process. The system also adjusts the required fluid flow rate based on the medication used in the infusion bottles and the characteristics of the medication.

[0020] Fifth, during the infusion process through the first infusion bottle, once the liquid sensor no longer detects liquid, the infusion is considered complete, and the sensor illuminates red, transmitting the message to the main controller. At this point, the automatic telescopic frame initiates an upward movement, disengaging the infusion needle from the completed infusion bottle. The needle remains stationary in the required position. Next, the servo motor drives a rotating disk at its output to rotate clockwise. This clockwise rotation of the disk drives several rotating plates, which in turn rotate their corresponding storage devices. The storage components originally containing the contents of the first infusion bottle are then activated. In the connecting assembly, the helical gear, initially not engaged with several helical gears on the auxiliary disk, engages through rotation. The helical gear not only rotates synchronously with the rotating disk but also rotates around its own axis due to the engagement. This rotation drives the corresponding connecting shaft, which in turn drives the corresponding connecting block. The connecting block's rotation, in turn, drives the corresponding lower fixing component. Meanwhile, the corresponding limiting block slides within the release groove on the corresponding connecting disk. The corresponding upper fixing component and the corresponding mesh pocket are also in a coordinated motion state. During the rotation of the corresponding lower fixing component, the limiting shaft inserted into it, when vertically downward, is affected by gravity. The IV bottle will fall into the storage box. As the corresponding lower fixing component rotates, causing the corresponding mesh bag to rotate approximately 180 degrees, the first IV bottle inside the mesh bag will fall into the storage box. Finally, when the helical gear disengages from several helical gears on the auxiliary plate, the helical gear rotates exactly one full rotation, or 360 degrees. At the same time, the servo motor also drives the rotating plate to rotate 60 degrees, and the corresponding storage component returns to its original state. The entire process completes the unloading of the IV bottle after infusion. After the first IV bottle is unloaded, the IV bottle in the next storage component moves to the infusion position directly above the fixing frame. Then, the automatic telescopic frame moves downward to complete the infusion. The IV needle is inserted again into the required IV bottle, completing the automatic IV bottle replacement. This provides continuous treatment for the patient and avoids situations where the patient forgets to call for a replacement, which could lead to blood backflow. Furthermore, it eliminates the need for medical staff to repeatedly change IV bottles, significantly reducing their workload and effectively improving treatment efficiency and quality. After the treatment is completed through the automatic IV bottle replacement cycle, an alarm on the display reminds the patient or their family to call for medical staff. All used IV bottles are stored in a storage box for easy collection by medical staff. The entire treatment process is very convenient. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] This invention provides an automatic fluid replacement device, including an automatic telescopic frame 1 that can be automatically extended and retracted for height adjustment. The lower end of the automatic telescopic frame 1 is provided with several movable and self-locking casters 11. The upper end of the automatic telescopic frame 1 is provided with a rotating device 2. The rotating device 2 is provided with several storage devices 3 for storing infusion products, and the several storage devices 3 are evenly arranged around each other. The telescopic frame of the automatic telescopic frame 1 is provided with an auxiliary flipping device 4 for flipping and engaging the several storage devices 3. The non-telescopic frame of the automatic telescopic frame 1 is provided with a fixing frame 12, which is located directly below the infusion product to be infused. The fixing frame 12 is provided with a mechanical clamp 14 for clamping the infusion needle 6. The fixing frame 12 is also provided with a liquid sensor 13 for detecting the liquid inside the infusion tube. The telescopic frame of the automatic telescopic frame 1 is also provided with a storage box 15 for storing and collecting used infusion products. The non-telescopic frame of the automatic telescopic frame 1 is provided with a display screen 16.

[0041] This device is applicable to various types of infusion products, including plastic infusion bottles 5, infusion bags, and glass infusion bottles 5. It can be used in various lengths and diameters, offering a wide range of applications. After medical staff place the infusion bottles 5 containing the therapeutic drugs in sequence, the device automatically replaces and cycles the bottles, completing the treatment process and providing continuous care for the patient. This eliminates the need for patients or their families to call for bottle replacements due to negligence. Furthermore, it eliminates the need for medical staff to repeatedly change the bottles, significantly reducing their workload and effectively improving treatment efficiency and quality.

[0042] This device has several self-locking casters 11 that are movable and have a self-locking function, allowing it to be moved freely to the desired treatment location or storage location.

[0043] Reference Figures 1 to 14 As shown, the entire infusion treatment process of this device is as follows: First, place the corresponding therapeutic drugs in the storage box 15 according to their order → Then, place them sequentially into the corresponding storage components according to the infusion sequence → Clamp the infusion needle 6 and clamp the liquid sensor 13 onto the infusion tubing → The automatic telescopic frame 1 moves downwards to allow the infusion needle 6 to puncture and insert into the infusion bottle 5 → Once the liquid sensor 13 no longer detects liquid, the initial infusion is complete → The automatic telescopic frame 1 starts moving upwards to disengage the infusion needle 6 from the completed infusion bottle 5 → The servo motor 21 drives the infusion bottle 5 in the next storage component 32 to move to the fixed frame 1. 2. The infusion position is directly above the infusion point. The automatic telescopic frame 1 moves downward to allow the infusion needle 6 to be inserted into the required infusion bottle 5 again. The infusion bottle 5, after the infusion is completed, is rotated to the top of the storage box 15. With the cooperation of the flipping auxiliary device 4, the storage component 32 drives the completed infusion bottle 5 to flip 180 degrees and fall down. The storage component 32 rotates 180 degrees again to return to its original state to prepare for subsequent use. After the liquid sensor 13 senses the liquid, the treatment operation proceeds normally. After the treatment operation is completed through the cyclic automatic replacement operation, the display screen 16 alarms to remind the patient or family to call medical staff.

[0044] Preferably, the rotating device 2 includes a servo motor 21, a rotating disk 22, and a rotating plate 23. The servo motor 21 is disposed inside the upper end of the retractable frame of the automatic telescopic frame 1. The rotating disk 22 is disposed on the output end of the servo motor 21. Several rotating plates 23 are provided, and the several rotating plates 23 are evenly arranged around the lower end of the rotating disk 22. Several placement slots 221 are evenly arranged around the outer side of the rotating disk 22, and the positions of the several placement slots 221 and the several rotating plates 23 are in a one-to-one correspondence.

[0045] The rotating disk 22 has several placement slots 221 evenly arranged around its outer side, which makes it easy for medical staff to place the infusion bottle 5 into the corresponding storage component 32.

[0046] Reference Figure 3 As shown, when administering intravenous infusion to a patient, medical staff stand opposite the display screen 16. First, by touching the display screen 16, they adjust the height of the automatic telescopic frame 1 to a height suitable for placing and hanging the infusion bottles 5. After adjustment, the medical staff place the prepared infusion bottles 5 sequentially into the storage box 15, referring to… Figure 3 As shown, place the first infusion bottle 5 requiring infusion into the storage component 32 located directly above the display screen 16, with the infusion bottle 5 placed head down. After placing the first infusion bottle 5, refer to... Figure 13 and Figure 14 As shown, the limiting shaft 325 is inserted into the inclined groove 324 on the lower fixing member 323 at an angle, and is positioned exactly at the bottle neck guard ring 51 of the infusion bottle 5 to limit the infusion bottle 5. By operating the display screen 16 again, the servo motor 21 is started. The servo motor 21 rotates clockwise, driving the rotating disk 22 to rotate clockwise. The clockwise rotation of the rotating disk 22 drives several rotating plates 23 to rotate clockwise, thereby driving several clockwise storage components 32 to rotate. After rotating accurately by 60 degrees, the operation stops. At this time, the storage component 32 plate, which was originally located above the storage box 15, moves to the top of the display screen 16. Then, the second infusion bottle 5 that needs infusion is placed in the storage component that is now located directly above the display screen 16. In step 32, after completing the placement and limiting of the infusion bottle 5 according to the above operations, the servo motor 21 is started and rotates 60 degrees each time to place the infusion bottles 5 required for infusion treatment into the corresponding storage components 32 in sequence. After all the infusion bottles 5 required for infusion treatment have been placed, the servo motor 21 is started again to move the storage component 32, which originally stored the first required infusion bottle 5, to a position directly above the fixed frame 12. This completes the sequential placement of infusion drugs as required, setting a benchmark for subsequent automatic infusion and fluid replacement operations. The entire placement process is relatively simple and will not lead to errors in the order of drug placement, greatly bringing convenience to medical staff and providing patients with an accurate treatment process to promote better recovery.

[0047] Preferably, each of the plurality of storage devices 3 includes a connecting assembly 31 and a storage assembly 32. The connecting assembly 31 includes a connecting shaft 311, a connecting disk 312, a connecting block 313, and a limiting block 314. The connecting disk 312 is disposed at the lower end of the rotating plate 23. The connecting shaft 311 is rotatably connected to the axis of the connecting disk 312, with both ends located on both sides of the connecting disk 312. One end of the connecting block 313 is connected to the first end of the connecting shaft 311. The connecting disk 312 is provided with a circular groove 315. The end of the limiting block 314 is located within the circular groove 315 and is... The sliding fit configuration includes several storage components 32, each comprising an upper fixing member 321, a mesh pocket 322, and a lower fixing member 323. The upper fixing member 321 is connected to the first end of the limiting block 314 and is made of rubber. The lower fixing member 323 is connected to the other end of the connecting block 313 and is connected by the mesh pocket 322. The lower fixing member 323 is ring-shaped and has an inclined groove 324, into which a limiting shaft 325 can be inserted.

[0048] Several storage components 32 are composed of an upper fixing member 321, a mesh bag 322, and a lower fixing member 323. Because the infusion bottle 5 is placed inside the mesh bag 322 with the bottle opening facing downwards, and because the mesh bag 322 itself is stretchable and can be shaped to fit a corresponding fit by weight, this device can be used for different types of infusion products, such as plastic infusion bottles 5, infusion bags, and glass infusion bottles 5, and can be used for different lengths and thicknesses. However, because the mesh bag 322 itself does not have the strength or function of limiting and fixing the infusion bottle 5, this device uses a limiting shaft 323. The needle 6 is inserted at an angle and abuts against the ring 51 of the infusion bottle 5. During the puncture, the upward pressure generated by the needle 6 puncturing the infusion bottle 5 is transmitted to the limiting shaft 325. Since the limiting shaft 325 is inclined, the pressure is transmitted to the lower fixing member 323. The pressure of the lower fixing member 323 is then transmitted to the corresponding connecting device. Finally, the pressure is transmitted to the connecting plate 312 through the limiting block 314, and then dissipated after being transmitted to the automatic telescopic frame 1 and the ground. The limiting block 314 can prevent the corresponding storage component 32 from shaking due to gravity or inertia, which would affect the accuracy of the needle 6 puncture insertion.

[0049] Preferably, the auxiliary flipping device 4 includes a helical gear 41, an auxiliary rod 42, and an auxiliary disk 44. The auxiliary disk 44 is sleeved on the extendable frame of the automatic telescopic frame 1. There are several helical gears 41, which are respectively set on the ends of corresponding connecting shafts 311. The auxiliary disk 44 has several helical teeth that mesh with the helical gears 41. The auxiliary disk 44 also has a circular track 45. There are several auxiliary rods 42, which are respectively set on corresponding connecting shafts 311 and all facing downward. The lower end of each of the auxiliary rods 42 is provided with a slider 43. The sliders 43 are equidistantly arranged around the circular track 45 and are all slidably engaged. The center of the clamping point of the mechanical clamp 14 is exactly below the axis of the lower fixing member 323. After the conventional infusion puncture needle is clamped by the mechanical clamp 14, its central axis is exactly below the axis of the lower fixing member 323.

[0050] It also includes a main controller, in which the mechanical clamp 14, liquid sensor 13, servo motor 21 and automatic telescopic frame 1 are all controlled by the main controller. The display screen 16 has an alarm function and is electrically connected to the main controller. The main controller can perform operation design programs through the display screen 16.

[0051] Initially, medical staff can connect the computer control system on the workbench to the main controller in this device based on the patient's basic information and medication usage, synchronizing the information on the display screen 16. Based on this synchronized information, medical staff can accurately place the corresponding infusion bottles 5 in sequence, ensuring the accuracy of the entire treatment. If medication is used incorrectly, the situation can be understood immediately and corresponding measures can be taken. After the required infusion bottles 5 are placed in sequence, medical staff can set the specified operation mode and process on the display screen 16. The specified operation mode and process involves inputting the number of infusion bottles 5 in sequence. After the setting is completed, once the number is reached, the liquid sensor 13 will not detect any liquid, and the display screen 16 will generate an alarm indicating that the entire infusion process has ended. The required liquid flow rate can also be adjusted according to the required medication and the characteristics of the medication in the infusion bottles 5.

[0052] After several infusion bottles 5 containing therapeutic drugs are placed in sequence, medical staff place the infusion needle 6 onto the mechanical clamp 14. The mechanical clamp 14 holds the infusion needle 6, ensuring that the needle 6 has sufficient insertion length and faces the infusion bottle 5. Then, the liquid sensor 13 is clamped onto the infusion tubing connected to the infusion needle 6. The liquid sensor 13 in this device is a non-contact liquid level sensor, model Y26A. When liquid is detected, the light is off; when no liquid is detected, the red light illuminates and transmits this information. At this time, the automatic telescopic frame 1 is activated, causing several storage devices 3 on the rotating device 2 to move downwards. After moving downwards a certain distance, the clamped needle will pierce and insert into the first infusion bottle 5 in the storage assembly 32 located directly above the fixed frame 12, thus completing the piercing and insertion of the infusion needle 6 into the infusion bottle 5.

[0053] Preferably, the storage box 15 has a flexible layer inside, and the inside of the storage box 15 is inclined downwards; by having a flexible layer inside the storage box 15, the infusion bottle 5 is prevented from being subjected to a large impact when it falls, and the inclination downwards arrangement of the inside of the storage box 15 facilitates the collection and storage of the infusion bottle 5.

[0054] The helical gear 41 on the connecting shaft 311 of the storage device 3 directly above the infusion puncture needle held by the mechanical clamp 14 is about to contact the matching helical teeth on the auxiliary disk 44. The number of helical teeth on the auxiliary disk 44 is enough for the corresponding helical gear 41 to rotate one revolution.

[0055] During the infusion process through the first infusion bottle 5, once the liquid sensor 13 no longer detects liquid, the infusion is considered complete, and the sensor illuminates a red light, transmitting the message to the main controller. At this point, the automatic telescopic frame 1 initiates an upward movement, disengaging the infusion needle 6 from the completed infusion bottle 5. The infusion needle 6 remains stationary in the required position. Next, the servo motor 21 drives the rotating disk 22 on its output end to rotate clockwise. The clockwise rotation of the rotating disk 22 causes several rotating plates 23 to rotate clockwise, which in turn causes the corresponding storage devices 3 to rotate. The storage components 32 originally containing the first infusion bottle 5 and their corresponding connecting components 31... The helical gear 41, initially not engaged with the other helical gears 41 on the auxiliary disk 44, engages through rotation. The helical gear 41 not only rotates synchronously with the rotating disk 22 but also rotates around its own axis due to the engagement. This rotation drives the corresponding connecting shaft 311, which in turn drives the corresponding connecting block 313. The rotation of the connecting block 313 then drives the corresponding lower fixing member 323. The corresponding limiting block 314 slides within the release groove 316 on the corresponding connecting disk 312. The corresponding upper fixing member 321 and the corresponding mesh pocket 322 are also in a coordinated motion state. During the rotation of the corresponding lower fixing member 323, the corresponding lower fixing member 323 is inserted... When the limiting shaft 325 is vertically downward, it will fall into the storage box 15 due to gravity. As the corresponding lower fixing part 323 rotates, it drives the corresponding mesh bag 322 to rotate nearly 180 degrees. The first infusion bottle 5 inside the mesh bag 322 will fall into the storage box 15. Finally, when the helical gear 41 disengages from the meshing state of several helical gears 41 on the auxiliary disk 44, the helical gear 41 rotates exactly one revolution, which is 360 degrees. At the same time, the servo motor 21 drives the rotating disk 22 to rotate 60 degrees. The corresponding storage component 32 returns to its original state. The whole process completes the unloading operation of the infusion bottle 5 after infusion. After the first infusion bottle 5 is unloaded, the infusion bottle 5 in the next storage component 32 moves to the fixing frame 12. At the infusion site directly above, the automatic telescopic frame 1 moves downwards to allow the infusion needle 6 to be inserted again into the required infusion bottle 5. This completes the automatic replacement of the infusion bottle 5, providing continuous treatment for the patient and preventing situations where the patient forgets to call for a change, which could lead to blood backflow. Furthermore, it eliminates the need for medical staff to repeatedly change the infusion bottle 5, significantly reducing their workload and effectively improving treatment efficiency and quality. After the treatment is completed through the automatic replacement of the infusion bottle 5, the display screen 16 alarms to remind the patient or their family to call for medical staff. All used infusion bottles 5 are collected in the storage box 15 for easy collection by medical staff.The entire treatment process was very convenient.

[0056] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
