DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and functional effects of the present invention easy to understand, the present invention will be further 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 are within the scope of protection of the present invention.

[0037] [Example 1] In order to address the shortcomings of the existing technology, such as Figure 1 , 2 As shown, the present invention provides an outpatient infusion stand with a reminder function, comprising a reminder function module and a support frame 1, the support frame 1 is provided with a fixing seat 3 for fixing at least two infusion bottles 001, and a replacement device 2 is provided between the fixing seat 3 and the support frame 1, for realizing automatic replacement of the infusion bottle 001 and automatic insertion and removal of the tube head 021 on the infusion tube 002; The top of the support frame 1 is fixedly connected to any position of the transmission part on the replacement device 2, and at least two holes are provided on the fixing seat 3 for fixing the infusion bottle 001. Any mechanism known to technicians in this field for clamping or fixing the infusion bottle 001 is arranged at the hole, such as a spring clamp, or a push plate driven by a bolt to clamp and fix the infusion bottle 001, or a soft pad for increasing the friction coefficient is arranged at the hole.

[0038] It should be noted that the present embodiment can be applied to any outpatient infusion stand with a reminder function that is well known to technicians in the field, such as infrared liquid level sensing, gravity sensing, and image acquisition and analysis based on machine learning and other such reminder functions. Therefore, in the present embodiment, the specific structure of the reminder function module and its operating principle are not further limited. Technicians in the field can refer to the existing technology and common knowledge to set up and arrange the reminder function module, and no excessive elaboration is made in the present embodiment.

[0039] During the infusion process, the infusion bottle 001 to be infused is placed on the fixing seat 3 for fixing. The fixing seat 3 is customized to fix the hole position of the infusion bottle 001 according to the actual implementation requirements, and then the infusion tube 002 is fixed to the replacement device 2 based on the position of the tube head 021 on it, and the end of the infusion tube 002 away from the tube head 021 is connected to the patient's body for normal infusion; After the infusion of one of the infusion bottles 001 is completed or is close to being completed, if there is a need for continuous infusion, the replacement device 2 is started, or the replacement device 2 starts automatically after receiving the electrical signal of the reminder function module, and drives the fixing seat 3 to change the position of the infusion bottle 001, and at the same time, performs an insertion and removal action on the tube head 021 to realize automatic replacement of the infusion bottle 001.

[0040] Specifically, Figure 3 As shown, a replacement device 2 in an outpatient infusion stand with a reminder function, the replacement device 2 includes a driving mechanism 21 and a plug-in mechanism 22, and the transmission rule of the driving mechanism 21 and the plug-in mechanism 22 is: during the normal driving process of the driving mechanism 21, the fixed seat 3 is driven to rotate intermittently, and during the intermittent period when the fixed seat 3 stops rotating, the driving mechanism 21 drives the tube head 021 to perform plug-in and pull-out actions through the plug-in mechanism 22.

[0041] Further, such as Figures 3 to 6As shown, a driving mechanism 21 and a plug-in mechanism 22 for a replacement device 2 in an outpatient infusion stand with a reminder function, the driving mechanism 21 includes a cam divider 212, one end of an input shaft 2122 on the cam divider 212 is provided with a motor 211, an output shaft 2121 of the cam divider 212 is fixedly connected to a fixed seat 3, and an end of the input shaft 2122 on the cam divider 212 away from the motor 211 extends to the outside and is connected to the plug-in mechanism 22, serving as the input end of the plug-in mechanism 22. When the motor 211 drives the input shaft 2122 to rotate, the plug-in mechanism 22 drives the tube head 021 to extend and retract to achieve plugging and unplugging; The reminder module is electrically connected to the motor 211. When the reminder module detects that the infusion is completed or nearly completed, it outputs an electrical signal to the motor 211 to start and rotate the motor 211. In this embodiment, the motor 211 may not be electrically connected to the reminder module, and manual intervention is required, which does not affect the normal operation of the replacement device 2. The non-input shaft 2122 and output shaft 2121 portion of the cam divider 212 is fixedly connected to the top of the support frame 1, the rotor of the motor 211 is fixedly connected to one end of the input shaft 2122, and the housing of the motor 211 is fixed to the non-output shaft 2121 and input shaft 2122 portion of the cam divider 212, or fixed to the outside; The plug-in mechanism 22 includes a fixing member 221 for fixing the pipe head 021 and a trigger rod 223 for fixing the fixing member 221. The trigger rod 223 is matched with a base frame 222 that slides relatively therewith, and a spring 224 is arranged between the base frame 222 and the trigger rod 223. A special-shaped cam 225 is arranged at a portion of the base frame 222 away from the trigger rod 223 and connected to one end of the fixing member 221. The special-shaped cam 225 is opposite to the trigger rod 223 and is fixedly connected to the input shaft 2122. A base 2211 is provided between the fixing member 221 and the trigger rod 223. The fixing member 221 is fixedly connected to the upper section of the trigger rod 223 through the base 2211. The fixing member 221 can be equivalently replaced by any fixing clamping assembly known to those skilled in the art, not limited to elastic fastening, or rigid fastening such as bolts. The plug-in mechanism 22 is fixed to the outside as a whole based on the base frame 222, or is fixedly connected to the position of the cam divider 212 other than the output shaft 2121 and the input shaft 2122. Two plates are arranged on the base frame 222, and the trigger rod 223 can slide on the two plates. A limiting protrusion is arranged on the trigger rod 223, and the spring 224 is located between one plate and the limiting protrusion on the trigger rod 223; the special-shaped cam 225 is rotatably connected to the base frame 222, or is directly fixedly connected to the input shaft 2122.

[0042] The special-shaped cam 225 is provided with a notch, and the special-shaped cam 225 is divided into a force-applying portion and a non-force-applying portion based on the notch. When the special-shaped cam 225 rotates to the non-force-applying portion based on the trigger rod 223, the trigger rod 223 is forced by the spring 224 to quickly reset. When the special-shaped cam 225 rotates to the force-applying portion based on the trigger rod 223, the trigger rod 223 drives the tube head 021 to continuously move toward the infusion bottle 001 through the fixing member 221. When the special-shaped cam 225 rotates until the notch thereon is directly opposite to the trigger rod 223 , the special-shaped cam 225 does not exert force on the trigger rod 223 .

[0043] It should be noted that the present invention is an outpatient infusion stand with a reminder function. Through the replacement device 2, during the infusion process, when the replacement device 2 is self-started or started, the rotor of the motor 211 rotates, driving the input shaft 2122 on the cam divider 212 to rotate, and the input shaft 2122 drives the cam in the cam divider 212 to rotate, and the output shaft 2121 is acted on by the internal cam of the cam divider 212. Regarding the structural installation and operation principle of the cam divider 212, those skilled in the art can understand that the cam divider 212 is constructed in proportion to the cam divider in the prior art. What needs to be defined are structural parameters such as the indexing angle and cam curve of the cam divider 212, which will not be described in detail here. The operation rules of the drive mechanism 21 and the plug-in mechanism 22 are as follows: Special shaped cam 225 Figure 4 , 5 In the structural state shown, the special-shaped cam 225 acts on the trigger rod 223 to the maximum extent, so that the trigger rod 223 extends, and the fixing member 221 drives the tube head 021 to be inserted into the infusion bottle 001, so as to achieve normal communication; When the motor 211 is started, the rotor of the motor 211 drives the input shaft 2122 to rotate, and at the same time, the input shaft 2122 drives the special-shaped cam 225 to rotate, so that the special-shaped cam 225 temporarily stops exerting force on the trigger rod 223. In this state, the spring 224 drives the trigger rod 223 to quickly reset, so that the fixing member 221 drives the tube head 021 to be pulled out of the infusion bottle 001. In this operation process, the output shaft 2121 is in a relatively static state; Thereafter, due to the continuous rotation of the input shaft 2122, the output shaft 2121 is driven to rotate, and the infusion bottle 001 is replaced based on the fixed seat 3. After the infusion bottle 001 is replaced, the output shaft 2121 is in a relatively static state again. In the static gap of the output shaft 2121, the special-shaped cam 225 completes one rotation and acts on the trigger rod 223 to the maximum extent, so that the trigger rod 223 drives the tube head 021 to insert the replaced infusion bottle 001 based on the fixing piece 221.

[0044] The above-mentioned operation rules are used as a complete replacement process of the infusion bottle 001, wherein, when the trigger rod 223 drives the tube head 021 to contact the infusion bottle 001 based on the fixing part 221 after being subjected to force, the output shaft 2121 should be in a relatively static state, that is, the spiral groove of the internal cam of the cam divider 212 is in a non-engaged state relative to the input shaft 2122.

[0045] It is worth mentioning that when the reminder module detects that the infusion is completed, the replacement device 2 is used to first drive the infusion bottle 001 on the infusion tube 002 to be quickly drawn out from the infusion bottle 001. During the process of drawing out the infusion tube 002, the infusion bottle 001 will not move. Then the replacement device 2 is continuously driven to drive the fixing seat 3 to rotate, and the positions of at least two infusion bottles 001 on the fixing seat 3 are replaced through the fixing seat 3. After the position of the infusion bottle 001 is replaced, the infusion tube 002 is driven to continuously extend to be inserted into the infusion bottle 001, so as to realize the replacement and automatic plugging and unplugging of the infusion bottle 001, thereby avoiding the safety hazard caused by the medical staff being unable to replace it in time due to excessive occupancy. In addition, the automated replacement of infusion bottles 001 minimizes manual operations, reduces the risk of infusion interruptions or errors caused by human errors, effectively reduces direct contact between medical staff and infusion bottles and infusion tubes, and reduces the risk of cross infection; In addition, the automated replacement process causes less disruption to patients, especially at night or when patients are resting, which can reduce disturbance to patients and improve the quality of medical services.

[0046] In this embodiment, those skilled in the art will appreciate that in order to achieve normal continuous infusion, that is, to avoid the liquid inside the drip bucket on the infusion tube 002 from flowing out during the process of replacing the infusion bottle 001, during the process of replacing the infusion bottle 001, the infusion bottle 001 should be replaced when a small amount of liquid is left in the infusion bottle 001 or when a large amount of liquid is left in the drip bucket of the infusion tube 002, so as to avoid the adverse effects of air inflow caused by the liquid inside the dripper flowing out.

[0047] Preferably, the fixing member 221 includes a fixed portion and a movable portion, a torsion spring is arranged between the movable portion and the fixed portion, and when the movable portion and the fixed portion are not subjected to force based on the torsion spring, the gap between the fixed portion and the movable portion is smaller than the thickness of the portion to be fixed on the tube head 021; after the fixing member 221 is clamped, it can be understood by those skilled in the art that the stiffness coefficient design of the torsion spring needs to be sufficient to stably clamp the tube head 021 without being subjected to external force; When the side of the fixing member 221 adjacent to the fixing seat 3 is a movable part, during the insertion of the tube head 021, when the driving mechanism 21 is not started, although the tube head 021 is subjected to a certain pulling external force, the good stability of the connection between the tube head 021 and the fixing seat 3 can be guaranteed; When the side of the fixing member 221 away from the fixing seat 3 is a movable part, during the insertion process of the tube head 021, even if the driving mechanism 21 is not started, if an emergency occurs, the tube head 021 can still be removed from the fixing member 221.

[0048] [Example 2] Based on the above-mentioned embodiment 1, in order to avoid the potential safety hazard of emptying the liquid in the drip bucket on the infusion tube 002 during the replacement of the infusion bottle 001, this embodiment is proposed: Specific, and Figure 3 As shown, a replacement device 2 in an outpatient infusion stand with a reminder function, the replacement device 2 also includes a head sealing mechanism 23, which is used to provide sealing protection for the tube head 021 when the tube head 021 is completely pulled out of the infusion bottle 001.

[0049] Further, such as Figure 7 As shown, a head sealing mechanism 23 for a replacement device 2 in an outpatient infusion stand with a reminder function, the head sealing mechanism 23 includes a rack 234 connected to a trigger rod 223, and a gear 233 meshing with the rack 234, two threaded rods 232 with opposite thread directions are arranged on both sides of the gear 233, and the two threaded rods 232 are each attached with a sealing plate 231 threadedly connected thereto respectively; One end of the rack 234 is fixedly connected to the base 2211 and is set up parallel to the trigger rod 223. The opposite ends of the two threaded rods 232 with opposite thread directions are fixedly connected to the two sides of the gear 233 respectively. A connecting frame is arranged between the two threaded rods 232 and the base frame 222. The threaded rods 232 and the connecting frame are rotatably connected through bearings, and one end of the connecting frame away from the threaded rods 232 is fixedly connected to the base frame 222. The two sealing plates 231 are located on the left and right sides of the tube head 021 , and a limiter 2312 is provided between the two sealing plates 231 for limiting the rotation of the sealing plates 231 . The limiter 2312 is rod-shaped, one end of which is fixedly connected to one of the sealing plates 231 and passes through the other sealing plate 231 .

[0050] It should be noted that the present invention is an outpatient infusion stand with a reminder function. Through the provided head sealing mechanism 23, during the replacement of the infusion bottle 001, when the trigger rod 223 is temporarily not affected by the special-shaped cam 225, the spring 224 drives the trigger rod 223, and the trigger rod 223 drives the tube head 021 to move downward based on the fixing part 221, the trigger rod 223 synchronously drives the rack 234 to move downward to drive the gear 233 to rotate, and the gear 233 then drives the two threaded rods 232 to rotate. During the rotation of the two threaded rods 232, the sealing plates 231 respectively attached thereto move relatively. When the trigger rod 223 moves and drives the tube head 021 to move to the same horizontal position as the two sealing plates 231, the two sealing plates 231 should cover and act on the tube head 021 to form an external seal for the tube head 021.

[0051] It is worth mentioning that in the process of automatic replacement of the infusion bottle 001 and automatic insertion and removal of the tube head 021, when the tube head 021 is pulled out, the plug-in mechanism 22 cooperates with the head sealing mechanism 23 to trigger the operation, so that the head sealing mechanism 23 provides sealing protection for the pulled out tube head 021. On the one hand, it can effectively prevent pollutants such as dust and bacteria in the air from entering the infusion tube 002 and causing the risk of infection. On the other hand, after the tube head 021 is sealed, the liquid in the infusion tube 002 no longer flows. During the entire cycle of replacing the infusion bottle 001, the continuous flow of liquid can be avoided, causing the liquid in the drip bucket to flow out, thereby preventing the safety hazard of air rushing into the infusion tube 002.

[0052] As a preferred embodiment, a soft seal 2311 is detachably connected to one side of the sealing plate 231 facing the pipe head 021; The soft seal 2311 can be made of any one of rubber, silicone, foam, sponge, etc., and can be detachably connected to the sealing plate 231. The detachable connection can be bonded by means of tape, or a groove with a structural size smaller than the soft seal 2311 can be opened on the sealing plate 231 to clip the soft seal 2311, so as to facilitate the replacement of the disposable soft seal 2311.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
