Description

Technical Field

[0001] The present invention relates to the technical field of infusion set connectors, and specifically to a multifunctional adjustable connector for an infusion set and a usage method thereof. Background Art

[0002] As is well known, an infusion set uses the principles of atmospheric pressure and hydrostatic pressure to infuse a large amount of sterile liquid and medicine into the body intravenously. During infusion, the liquid in the infusion bottle flows along a thinner infusion hose into the drip chamber under the action of atmospheric pressure. When the water column pressure in the drip chamber is greater than the human venous pressure, the liquid in the bottle will flow into the vein along the infusion hose. Among them, in order to reduce the number of liquid changes or perform multiple infusions simultaneously, there is also a double-connector infusion set, which has two bottle stopper puncture devices and can be inserted into two infusion bottles or infusion bags simultaneously to achieve dual-channel infusion and can connect two bottles of liquid at the same time.

[0003] Although the double-insert connector infusion set in the prior art can achieve dual-channel infusion and connect two bottles of liquid at the same time, it cannot meet the requirements when it is necessary to replace different infusion contents in sequence. It can only reduce the number of bottle changes for the same medicine or mix medicines for infusion, and is inconvenient to use; Based on the above-mentioned situation, we found that it is difficult for the infusion sets in the prior art to avoid the above problems at the same time. Therefore, we propose an adjustable connector that can be externally placed outside the double-insert connector infusion set, automatically closes when it detects that the liquid on one side has been finished, and at the same time opens the other side for infusion, and can be reciprocally switched, so as to reduce the number of bottle changes, extend the bottle change time, reduce the workload of medical staff, and at the same time reduce the probability of empty bottles in various situations. Moreover, after use, it can be removed from the infusion set and recycled for subsequent use without increasing the production cost of the infusion set, a multifunctional adjustable connector for an infusion set. Summary of the Invention

[0004] (1) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a multifunctional adjustable connector for an infusion set and a usage method thereof, which has the advantages of being able to be externally placed outside the double-insert connector infusion set, automatically closing when it detects that the liquid on one side has been finished, and at the same time opening the other side for infusion, and can be reciprocally switched, so as to reduce the number of bottle changes, extend the bottle change time, reduce the workload of medical staff, and at the same time reduce the probability of empty bottles in various situations. Moreover, after use, it can be removed from the infusion set and recycled for subsequent use without increasing the production cost of the infusion set.

[0005] (2) Technical Solutions The above technical object of the present invention is achieved by the following technical solutions: A multifunctional adjustment joint for an infusion set, comprising an adjustment part, a bottle support part, and an infusion tube. The infusion tube includes a flexible tube part. At the top of the flexible tube part, there are two puncture tubes, and at the top of the puncture tubes, there are bottle stopper needles installed. The bottle support part includes a bottom ring. On the outer side of the bottom ring, there is a support rope fixedly connected. At the top of the support rope, there is a top ring fixedly connected. The top ring is made of elastic ribs. At the top of the top ring, there is a weighing sensor movably connected. On the outer side of the bottom ring, there is a matching component movably connected. The adjustment part includes two groups of adjustment frames. Between the opposite sides of the two groups of adjustment frames, there is a guide frame fixedly connected. Inside the guide frame, there is a slider slidably connected. At the front side of the slider, there is a wheel frame movably connected. On the outer side of the wheel frame, there are two rollers movably connected. On the outer side of the rollers, there are rubber sleeves. At the front side of the adjustment frame, there is a pressing frame movably connected. At the front side of the pressing frame, there is a connecting rib fixedly connected. The inner side of the pressing frame and the rollers are slidably connected. The two puncture tubes are respectively arranged between the two groups of adjustment frames. The side of the roller close to the puncture tube is in contact with the puncture tube. The rear side of the adjustment frame is inclined, and the directions of the two adjustment frames are opposite.

[0006] By adopting the above technical solutions, through the setting of the bottle support part, it is used to fix the infusion bottle and can also provide a supporting effect when infusing in some glass containers. When hanging, its weighing sensor can detect the weight of the infusion container in real time. The structure formed by the support rope and the bottom ring surrounds the infusion container from the outside, so that both bag-shaped containers and bottle-shaped containers can be fixed for use. The set adjustment part is used to adjust the infusion tube. By setting the adjustment frame in cooperation with the pressing frame, it is convenient to fix the two puncture tubes inside the adjustment frame. The set guide frame is used to connect the two adjustment frames and at the same time limit the slider. When the slider moves vertically along the guide frame, it will drive the wheel frame and the rollers to move vertically along the pressing frame. When the rollers move, since the two groups of adjustment frames are set in opposite directions, at this time, one side of the roller does not press the puncture tube, and the other side of the roller presses the puncture tube so that the liquid medicine in it cannot flow. Changing the pressing direction of the roller can achieve the effect of switching the infusion container for infusion.

[0007] The present invention is further set as: The matching component includes a moving ring. The moving ring is sleeved on the outer side of the bottom ring. At the top of the moving ring, there is a flexible frame fixedly connected. At the top of the flexible frame, there is a connecting clip fixedly connected. The connecting clip is stuck on the outer side of the top ring. On the outer side of the flexible frame, there is an adjusting clip movably connected. At the outer side of the adjusting clip, there is a horizontal frame fixedly connected. On the outer side of the horizontal frame, there are a code scanning module and a detection module installed. The detection module is an infrared opposed self-reflection module.

[0008] With the above technical solution, by setting a movable ring, it is used to adjust the horizontal position of the matching component relative to the bottom ring, so that the soft frame connected thereto and the structures thereon are located at a position convenient for use. Before use, the top of the soft frame can be fixed outside the top ring through a connecting clip to keep it relatively vertical. Subsequently, the position of the adjusting clip can be adjusted to achieve the effect of adjusting the vertical height of the horizontal clip, so that the code scanning module and the detection module can scan different positions of the infusion container. The code scanning module can assist in scanning the code of the infusion container, and the detection module can detect whether there is any remaining liquid medicine inside the infusion container at the current position.

[0009] The present invention is further configured as: the adjusting clip includes a sliding frame, a connecting piece is slidably connected to the inner side of the sliding frame, a pressing piece is arranged on the inner side of the sliding frame, a pressing piece is arranged on the outer side of the sliding frame, both the pressing piece and the pressing piece are fixedly connected to the connecting piece on the side close to the connecting piece, a pressing spring is fixedly connected to the outer side of the pressing piece, the side of the pressing spring away from the pressing piece is fixedly connected to the sliding frame, and the soft frame is clamped between the pressing piece and the sliding frame.

[0010] With the above technical solution, by setting a sliding frame, the adjusting clip can be moved along the soft clip. When movement is required, the operator needs to press the pressing piece. At this time, the pressing piece moves away from the soft frame, so that there is space inside the sliding frame for the adjusting clip to move. After moving to the required position, the pressing piece is no longer pressed. At this time, the pressing spring pushes the pressing piece, so that it cooperates with the sliding frame to press the soft frame to the current position for locking.

[0011] The present invention is further configured as: the pressing frame includes two vertical bars, a hinge and an inserting piece. The hinge is fixedly connected to the right side of the right vertical bar. The side of the hinge away from the vertical bar is rotatably connected to the right adjusting frame. The inserting piece is fixedly connected to the top of the connecting rib. A chamfer is arranged on the side of the inserting piece close to the adjusting frame, and a through groove is opened inside the inserting piece.

[0012] With the above technical solution, by setting the vertical bars to be fixed through the connecting rib for use as a whole, the hinge is used to enable the pressing frame to be unfolded or combined along the adjusting frame, so as to facilitate the disassembly and assembly of different infusion devices. The provided inserting piece is used to assist in locking the pressing frame and the adjusting frame.

[0013] The present invention is further configured as: the guiding frame includes a main frame, a control motor is installed on the top of the main frame, a lead screw is rotatably connected to the inside of the main frame, the outside of the lead screw is threadedly connected to a slider, a locking card is fixedly connected to the top of the front side of the main frame, and the bottom of the lead screw extends out of the main frame.

[0014] With the above technical solution, by setting up a control motor, it is convenient to automatically drive the rotation of the lead screw and adjust the rotation direction according to the consumption of the weighing sensor and the detection module, so as to facilitate the control of the vertical position of the slider inside the main frame by the lead screw. As a driving control component for switching different infusion containers, the bottom of the lead screw extends out of the main frame, which is convenient for manual rotation by personnel for manual use. The locking card is used to cooperate with the insertion piece to lock or unlock the structure.

[0015] The present invention is further configured as: the locking card includes a hollow shell, the inner side of the hollow shell is inserted with the insertion piece, a locking bar is slidably connected to the inner side of the hollow shell, a reset spring is fixedly connected to the top inside the locking bar, the bottom of the reset spring is fixedly connected to the hollow shell, a rounded corner edge is provided on the side of the locking bar close to the insertion piece, and the locking bar is inserted into the through groove inside the insertion piece.

[0016] With the above technical solution, by setting up a hollow shell, when it is necessary to close the pressing frame and the adjusting frame, the insertion piece will be inserted into the inside of the hollow shell, and the chamfer on its outer side can prevent it from being stuck during the insertion process. When continuously inserted into the hollow shell, the rounded corner edges of the rounded corner edge and the locking bar come into contact and press against each other, causing the entire locking bar to move upward until the through groove position of the insertion piece is located at the locking bar. At this time, the reset spring rebounds, and the locking bar will be stuck into the through groove to complete the locking of the structure. When unlocking, press down the locking bar to move it out of the inside of the through groove, and then the entire pressing frame can be rotated open along the hinge.

[0017] The present invention is further configured as: a mating concave block is fixedly connected to the front side of the slider, and a mating convex block is fixedly connected to the rear side of the wheel frame, and the mating concave block and the mating convex block are used in cooperation.

[0018] With the above technical solution, by setting up the mating convex block and the mating concave block, when the pressing frame and the adjusting frame are closed, the mating convex block will be inserted into the mating concave block to facilitate the movement of the driving wheel frame.

[0019] The present invention is further configured as: a tube pad is fixedly connected to the inside of the adjusting frame, and the front side of the tube pad contacts the puncture tube.

[0020] With the above technical solution, by setting up the tube pad, it is convenient to perform the actions of raising and limiting the puncture tube in contact with it.

[0021] The present invention is further configured as: the tube pad includes a raising block, limiting protrusions are fixedly connected to both sides of the raising block, a heat-conducting medium is filled in the cavity formed by the limiting protrusions, the raising block and the adjusting frame, sealing sheets are provided at the top and bottom of the cavity, and heating wires are installed inside the sealing sheets, and the heating wires are located inside the cavity.

[0022] With the above technical solution, the puncture tube is lifted to a position where it is convenient to be pressed by setting a lifting block. The set limiting protrusion is used to limit the extreme pressing position of the roller, avoiding damage to the puncture tube or deformation that is difficult to reset caused by excessive pressing. The heat-conducting medium inside the cavity formed by the limiting protrusion, the lifting block, and the adjusting frame cooperates with the heating wire to heat when needed, making the liquid medicine close to the human body temperature and reducing the stimulation of the liquid medicine to the patient. Since the lifting block is relatively thick, there is a certain attenuation in the temperature transfer process, and it is not easy for the liquid medicine to deteriorate or the puncture tube to be damaged by heat due to excessive temperature.

[0023] A method for using a multifunctional adjusting joint for an infusion set, comprising the following steps: S1. Before use, two containers can be scanned through the hospital's drug management system. Then, the two infusion containers are placed inside the bottle support part. When placing them, ensure that their bottle stopper parts are inside the bottom ring, and the top ring made of elastic bands is stretched to increase its circumferential area for the container to be placed inside the support rope. Also, the two infusion containers are respectively hung on the drip stand through the weighing sensors; S2. The infusion tubes are respectively inserted into the bottle stoppers through two puncture needles for liquid supply. Then, the adjusting frame and the pressing frame of the adjusting part are opened along the hinge, and the two puncture tubes are respectively located inside the two groups of adjusting frames and are in contact with the tube pads. Then, the pressing frame is clamped on the front side of the adjusting frame along the hinge. Manually rotate the bottom of the lead screw as needed to adjust the position of the connected slider until the wheel frame and the roller move to the top or bottom of the two groups of adjusting frames. Since the two groups of adjusting frames are set in opposite directions, at this time, one side of the roller does not press the puncture tube, and the other side of the roller presses the puncture tube, causing the liquid medicine in it to not flow; S3. After the infusion preparation is completed, the patient is infused through a venous needle. After the liquid medicine in one infusion container is infused, the weighing sensor senses that the weight of the bottom container decreases, and at the same time, the detection module receives a change in the intensity of the reflected infrared light. Therefore, it is judged that the container is infused to the required amount. At this time, a signal is transmitted to the control motor, and the control motor rotates to drive the lead screw to rotate. At this time, the position of the slider changes, and the two rollers move to the other side relative to the adjusting frame to switch the pressed puncture tube for the replacement of the infusion container; S4. After the liquid in the first infusion container is finished, the signal is simultaneously transmitted to the hospital's drug management system. The system automatically ends the liquid volume of the first infusion container and automatically starts to record the liquid of the second infusion container. After the first infusion container is finished, when the second infusion container is being infused, since the bottom pipeline of the first infusion container cannot output the liquid medicine, the subsequent infusion containers can be replaced at any time. When the second infusion container ends, the system automatically records the liquid volume of the second infusion container, and subsequent cyclic operations are performed.

[0024] (III) Beneficial effects Compared with the prior art, the present invention provides a multifunctional adjustment joint for an infusion set and a usage method, having the following beneficial effects: For the multifunctional adjustment joint for an infusion set and the usage method, by providing a bottle support part for fixing the infusion bottle, it can also provide a supporting effect when infusing in some glass containers. When hanging, its weighing sensor can detect the weight of the infusion container in real time. The structure formed by the supporting rope and the bottom ring surrounds the infusion container from the outside, enabling both bag-shaped containers and bottle-shaped containers to be fixed and used. The provided adjustment part is used to adjust the infusion tube. By providing an adjustment frame and a pressing frame, it is convenient to fix two puncture tubes inside the adjustment frame. The provided guide frame is used to connect two adjustment frames and at the same time limit the slider. When the slider moves vertically along the guide frame, it will drive the wheel frame and the roller to move vertically along the pressing frame. When the roller moves, since the two adjustment frames are arranged in opposite directions, at this time one side roller does not press the puncture tube, and the other side roller presses the puncture tube so that the liquid medicine therein cannot flow. Changing the pressing direction of the roller can achieve the effect of switching the infusion container for infusion. BRIEF DESCRIPTION OF THE DRAWINGS

The front side of the adjustment frame 11 is movably connected to a pressing frame 16. A connecting rib 17 is fixedly connected to the front side of the pressing frame 16. The inside of the pressing frame 16 is slidably connected to the roller 15. Two puncture tubes 32 are respectively arranged between the two groups of adjustment frames 11. The side of the roller 15 close to the puncture tube 32 is in contact with the puncture tube 32. The rear side of the adjustment frame 11 is inclined, and the directions of the two adjustment frames 11 are opposite. The provided adjustment part 1 is used to adjust the infusion tube 3. By arranging the adjustment frame 11 in cooperation with the pressing frame 16, it is convenient to fix the two puncture tubes 32 inside the adjustment frame 11. The provided guide frame 12 is used to connect the two adjustment frames 11 and at the same time limit the slider 13. When the slider 13 moves vertically along the guide frame 12, it will drive the wheel frame 14 and the roller 15 to move vertically along the pressing frame 16. When the roller 15 moves, since the two groups of adjustment frames 11 are arranged in opposite directions, at this time, one side roller 15 does not press the puncture tube 32, and the other side roller 15 presses the puncture tube 32 so that the liquid medicine in it cannot flow. Changing the pressing direction of the roller 15 can achieve the effect of switching the infusion container for infusion.

[0032] Among them, the pressing frame 16 includes two vertical bars 161, a hinge 162 and an insertion piece 163. The hinge 162 is fixedly connected to the right side of the right vertical bar 161. The side of the hinge 162 away from the vertical bar 161 is rotatably connected to the right adjustment frame 11. The insertion piece 163 is fixedly connected to the top of the connecting rib 17. A chamfer is provided on the side of the insertion piece 163 close to the adjustment frame 11, and a through groove is opened on the inner side of the insertion piece 163. By setting the vertical bar 161 to be fixed through the connecting rib 17 for use as a whole, the hinge 162 is used to enable the pressing frame 16 to be unfolded or combined along the adjustment frame 11, so as to facilitate the disassembly and assembly of different infusion sets. The provided insertion piece 163 is used to assist in locking the pressing frame 16 and the adjustment frame 11. The guide frame 12 includes a main frame 121.

A rounded edge is provided on the side of the locking bar 1242 close to the insertion piece 163. The locking bar 1242 is inserted into the through groove on the inner side of the insertion piece 163. By setting the hollow shell 1241, when it is necessary to close the pressing frame 16 and the adjustment frame 11, the insertion piece 163 will be inserted into the inside of the hollow shell 1241. The chamfer on its outer side can prevent it from being stuck during the insertion process. When continuously inserted into the hollow shell 1241, the rounded edges of it and the locking bar 1242 come into contact and press against each other, causing the entire locking bar 1242 to move upward until the through groove position of the insertion piece 163 is located at the locking bar 1242. At this time, the return spring 1243 rebounds, and the locking bar 1242 will be stuck into the through groove to complete the locking of the structure. When unlocking, press down the locking bar 1242 to move it out of the inner side of the through groove, and then the entire pressing frame 16 can be rotated open along the hinge 162. A mating concave block 4 is fixedly connected to the front side of the slider 13, and a mating convex block 5 is fixedly connected to the rear side of the wheel frame 14. The mating concave block 4 and the mating convex block 5 are used in cooperation. By setting the mating convex block 5 and the mating concave block 4,When the pressing frame 16 and the adjusting frame 11 are closed, the mating convex block 5 will insert into the mating concave block 4 to facilitate the movement of the driving wheel frame 14. A pipe pad 6 is fixedly connected to the inner side of the adjusting frame 11. The front side of the pipe pad 6 contacts the puncture tube 32. By providing the pipe pad 6, it is convenient to perform the actions of raising and limiting the puncture tube 32 in contact therewith. The pipe pad 6 includes a raising block 61. Limiting protrusions 62 are fixedly connected to both sides of the raising block 61. A heat-conducting medium is filled in the cavity formed by the limiting protrusions 62, the raising block 61 and the adjusting frame 11. Sealing sheets 63 are provided at the top and bottom of the cavity. A heating wire 64 is installed inside the sealing sheet 63. The heating wire 64 is located inside the cavity. By providing the raising block 61, the puncture tube 32 is raised to a position where it is convenient to be pressed. The provided limiting protrusions 62 are used to limit the extreme pressing position of the roller 15 to prevent damage to the puncture tube 32 or deformation that is difficult to reset caused by excessive pressing. The heat-conducting medium in the cavity formed by the limiting protrusions 62, the raising block 61 and the adjusting frame 11 cooperates with the heating wire 64 to be heated when needed, so that the liquid medicine is close to the human body temperature and the stimulation of the liquid medicine to the patient is reduced. Since the raising block 61 is relatively thick, there is a certain attenuation in the temperature transfer process, and it is not easy for the liquid medicine to deteriorate or the puncture tube 32 to be damaged by heat due to excessive temperature.

[0033] Working principle of this embodiment: First, open the pressing frame 16 from the adjusting frame 11 along the hinge 162, place the two puncture tubes 32 between the two groups of adjusting frames 11 respectively, and make the puncture tubes 32 contact the tube gasket 6. The heightening block 61 of the tube gasket 6 can heighten the puncture tubes 32 to a position convenient for operation, and the limiting protrusion 62 can prevent the roller 15 from pressing the puncture tubes 32 excessively. Close the pressing frame 16, and insert the insertion piece 163 into the hollow shell 1241 of the locking card 124. The chamfer of the insertion piece 163 ensures smooth insertion. As the insertion piece 163 goes deeper, the rounded edge of its rounded corner interacts with the rounded edge of the locking bar 1242 to move the locking bar 1242 upward. When the through slot of the insertion piece 163 reaches the position of the locking bar 1242, the return spring 1243 pushes the locking bar 1242 to snap into the through slot, completing the locking of the pressing frame 16 and the adjusting frame 11, ensuring that the mating convex block 5 on the rear side of the wheel frame 14 accurately inserts into the mating concave block 4 on the front side of the slider 13, making the connection between the wheel frame 14 and the slider 13 stable. If it is necessary to manually switch the infusion container, directly rotate the lead screw 123 extending from the bottom of the main frame 121. The lead screw 123 drives the slider 13 threadedly connected thereto to move vertically within the main frame 121 of the guide frame 12. The slider 13 drives the wheel frame 14 and the roller 15 to move vertically along the pressing frame 16 through the mating convex block 5 and the mating concave block 4. Since the two groups of adjusting frames 11 are in opposite directions, the movement of the roller 15 can switch the pressing state on the puncture tubes 32, realizing the switching of the infusion container. When the weighing sensor 24 senses a change in the weight of the infusion container, or the detection module 257 detects a change in the liquid medicine, the signal is transmitted to the control motor 122. The control motor 122 automatically drives the lead screw 123 to rotate, realizing the adjustment of the position of the slider 13, and then completing the switching of the pressing state of the roller 15 on the puncture tubes 32, automatically replacing the infusion container. When it is necessary to heat the liquid medicine to be close to the human body temperature to reduce the stimulation to the patient, start the heating wire 64. The heating wire 64 heats the heat-conducting medium filled in the cavity formed by the limiting protrusion 62, the heightening block 61 and the adjusting frame 11. The heat is transmitted to the liquid medicine in the puncture tubes 32 through the heightening block 61. Since the heightening block 61 is relatively thick, it can effectively prevent the liquid medicine from deteriorating or the puncture tubes 32 from being damaged due to excessive temperature. When it is necessary to disassemble, press down the locking bar 1242 to make it move out of the through slot of the insertion piece 163, and then rotate and open the pressing frame 16 along the hinge 162, and then maintenance operations such as inspecting, cleaning or replacing components of the internal structure of the adjusting part 1 can be carried out.

10. A method for using a multifunctional adjusting connector for an infusion set according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Before use, the two containers can be scanned through the hospital's drug management system, and then the two infusion containers are placed on the inner side of the bottle holder (2), and when placed, the bottle plugs are ensured to be located on the inner side of the bottom ring (21), and the top ring (23) made of elastic tendons is stretched to increase its circumferential area so that the containers can be placed on the inner side of the support rope (22), and the two infusion containers are hung on the bottle hanging rack through the weighing sensor (24); S2. Insert the infusion tube (3) into the bottle stopper through two puncture needles to supply liquid, then open the adjustment frame (11) and the pressure frame (16) of the adjustment part (1) along the hinge (162), and make the two puncture tubes (32) respectively located on the inner side of the two groups of adjustment frames (11) and contact with the tube pad (6), then clamp the pressure frame (16) on the front side of the adjustment frame (11) along the hinge (162), and manually rotate the bottom of the screw rod (123) as needed to adjust the position of the slider (13) connected thereto until the wheel frame (14) and the roller (15) move to the top or bottom of the two groups of adjustment frames (11).

At this time, the position of the slider (13) changes, and the two rollers (15) move to the other side relative to the adjustment frame (11) to switch the compressed puncture tube (32) to replace the infusion container; S4. After the liquid in the first infusion container is infused, the signal is transmitted to the hospital's drug management system at the same time. The system automatically ends the liquid volume of the first infusion container and automatically starts to enter the liquid in the second infusion container. After the infusion of the first infusion container is completed, when the second infusion container is infused, since the bottom pipeline of the first infusion container cannot output the liquid medicine, the subsequent infusion container can be replaced at any time. When the second infusion container ends, the system automatically enters the liquid volume of the second infusion container, and the subsequent cycle operation is carried out.
