Description

Technical Field

[0001] This invention relates to the field of pediatric outpatient clinics, and more particularly to an infusion chair for use in pediatric outpatient clinics. Background Technology

[0002] An infusion chair, also known as an IV drip chair, is a seat used by patients during intravenous infusions. Early infusion chairs were very simple, often made of chairs or sofas, with poor quality, safety, and ease of use. With the rapid development of modern medicine, infusion chairs have become increasingly scientifically designed, offering a wider range of functions. Pediatric infusion chairs are special chairs designed to facilitate intravenous treatment for children. These chairs are generally comfortable, taking into full account the physical characteristics and needs of children. They typically consist of an IV stand and a leather seat, with two positions: one for the infusion and one for the parent / attendant. Some infusion chairs are equipped with independent multimedia viewing devices to better serve pediatric infusion needs.

[0003] A search revealed a patent with publication number CN210096538U, which discloses a pediatric infusion chair, including an infusion chair body, a storage box connected above the armrests of the infusion chair body, a cushion rotatably connected above the storage box, an infusion stand connected to one side of the infusion chair body, a connecting rod placed inside the storage box, the connecting rod rotatably connected to the storage box, a mobile phone clip connected to the other end of the connecting rod via a universal ball joint, a storage slot above the cushion, and a strap connected to the side of the cushion.

[0004] The aforementioned patent designs a simple pediatric infusion chair, which includes a storage box above the armrests for placing items and straps to secure the child's arms and prevent needle misalignment due to arm movement. However, during infusions, children are prone to drowsiness due to the sedative and hypnotic components in the medication. When asleep, they may lean to one side, causing compression of the IV tubing or potentially breaking the needle, thus affecting the infusion's effectiveness. Furthermore, if the child is held by a caregiver during the infusion, it requires prolonged support and is physically demanding. Therefore, there is an urgent need for an infusion chair that allows the child to lean back comfortably during infusions and facilitates caregiver supervision. Summary of the Invention

[0005] In order to overcome the shortcomings of existing pediatric infusion chairs that cannot prevent children from falling over after dozing off, the present invention aims to provide an infusion chair for pediatric outpatient use that is easy to use and provides support for children who are dozing off.

[0006] To address the aforementioned technical problems, this invention provides an infusion chair for pediatric outpatient clinics, comprising an infusion chair, a leaning component, a buckle component, and an IV bag assembly. The infusion chair serves as the primary carrier for infusion, consisting of the chair's basic components: supporting legs, armrests, and a backrest. The backrest has two through openings, through which the leaning component is slidably connected. This leaning component provides safe support for children who become drowsy during infusion. The leaning component is activated by sliding back and forth across the openings in the backrest. A buckle component is located at the leaning part of the leaning component, locking it in place to ensure stable support. An IV bag assembly is located on one side of the infusion chair, used to hang the IV bag. The assembly can be raised and lowered to facilitate hanging the IV bag for medical staff, thus aiding in the infusion process.

[0007] Preferably, the support assembly includes a support block, a flip block, a locking plate, a limiting frame, and a limiting rod. The backrest of the infusion chair has a support block slidably connected to it via an opening, providing support for children. There are two support blocks, left and right, each with a flip block rotatably connected to its rear end. The two flip blocks are connected by a locking plate located at the rear ends of the two flip blocks. A limiting frame for limiting the flip blocks is fixed to the back of the infusion chair. The limiting frame has a recessed slot, and a limiting rod slides through the slot. When the flip block rotates downwards into the slot, the limiting rod lowers, locking the flip block in the limiting frame. This reduces the space occupied by the flip block protruding outwards after the support block retracts into the infusion chair, and also locks the support assembly when not in use, preventing it from affecting the normal use of the infusion chair.

[0008] Preferably, the latching assembly includes a toggle bar and a first spring. A toggle bar for latching is provided at the connection between the support block and the flipping block. Two toggle bars are provided, and a first spring is elastically connected between the two toggle bars. The toggle bar is slidably connected to the upper surface of the flipping block. The toggle bar consists of a bar and a lever. When the bar is latched into the opening on the support block, it horizontally restricts the support block and the flipping block. After the support assembly slides backward, the lever is used to press the bar inward. The bar overcomes the elastic force of the first spring and moves away from the opening on the support block. The bar then no longer restricts the support block and the flipping block, allowing the flipping block to flip, reducing its space occupation.

[0009] Preferably, the infusion assembly includes a support rod, a motor, a bidirectional threaded rod, and an infusion rack. A vertical support rod is connected to one side of the infusion chair. A motor is located at the upper end of the support rod, and the output shaft of the motor is located inside the support rod. The internal rotation of the support rod is connected to the bidirectional threaded rod, which is connected to the output shaft of the motor. The upper end of the support rod is slidably connected to the infusion rack, which consists of multiple outwardly radiating perforated plates. The bidirectional threaded rod meshes with the infusion rack through its threads. When the bidirectional threaded rod rotates, the threads drive the infusion rack to rise and fall.

[0010] Preferably, it also includes a clamping component. Each perforated plate on the IV rack is provided with a clamping component, which can further clamp the IV bottle placed on the IV rack to prevent the IV bottle from falling after being hung up.

[0011] Preferably, the clamping assembly includes an elastic frame, a linkage wedge, a clamping plate, a linkage rotating plate, and a second spring. Each perforated plate on the IV rack has multiple grooves, through which the elastic frame is slidably connected. The linkage wedge is slidably connected to each elastic frame. The upper side of each perforated plate on the IV rack is slidably connected to a clamping plate through a groove. The clamping plates are symmetrically arranged at the clamping openings of the perforated plates. The IV rack is connected to the linkage rotating plate via a rotating rod. When the linkage wedge is squeezed by the IV bottle, it will squeeze the linkage rotating plate to rotate. The linkage rotating plate and the IV rack are elastically connected to a second spring for resetting. After the linkage rotating plate rotates, it can squeeze and push the clamping plate inward to stably clamp the placed IV bottle.

[0012] Preferably, it also includes an adjustment assembly, which includes an adjustment threaded rod, a push wedge, an elastic pad, and a third spring. Both the leaning block and the flipping block have through holes inside. The leaning block and the flipping block are rotatably connected to the adjustment threaded rod through the through holes. The push wedge is slidably connected inside the leaning block. The third spring is elastically connected between the push wedge and the leaning block. The push wedge is connected to the elastic pad. After the adjustment threaded rod is screwed into the leaning block through the thread, it will press against the inclined surface of the push wedge. The push wedge pushes the elastic pad to move towards the side where the child is leaning, so that the elastic pad can expand and contract as needed to meet the different leaning needs of the child.

[0013] Preferably, it also includes a collection assembly, which includes a placement plate, a collection box, a box cover, and a filter screen. The placement plate is provided on one side of the seat of the infusion chair. The placement plate is provided with a collection box for placing the infusion bottle after the infusion is completed. The top opening of the collection box is covered with a box cover. The inside of the collection box is provided with a filter screen, which can filter out the residual medicine after the infusion bottle is poured out, so as to separate the infusion bottle and the residual medicine and improve the efficiency of subsequent processing of the infusion bottle.

[0014] Preferably, it also includes a footrest assembly, which includes a linkage rod, a push-out plate, and a footrest pad. The linkage rod is fixed to the lower side of one of the backrest blocks, and the lower end of the linkage rod is provided with a push-out plate. The footrest pad is slidably connected to the lower side of the seat cushion of the infusion chair. The front end of the push-out plate contacts the footrest pad. When the backrest block is pushed out for use, it will drive the footrest pad to slide out of the seat cushion of the infusion chair. The footrest pad can support the child's feet while sitting on the infusion chair, so that when the child is dozing off, his feet are supported and lifted by the footrest pad, improving the child's comfort during infusion.

[0015] Preferably, it also includes a storage component, which includes a storage frame. The storage frame is provided on the armrest of the infusion chair. The storage frame can be used to place objects that children use for entertainment during infusion, thereby effectively diverting children's attention during infusion and preventing children from crying during infusion.

[0016] Beneficial effects:

[0017] This invention provides support for children who are drowsy and fall over by pushing the backrest and flipping block out from the back of the infusion chair and using a lever to keep them horizontally within the chair. The adjustable screw rod can be turned to adjust the position of the elastic pad protruding from the backrest, providing adaptive support for children of different ages. This prevents children from falling over due to drowsiness, which would hinder the infusion process, and also improves the comfort of children when they fall over.

[0018] This invention enables the IV stand to rise and fall via a motor, allowing medical staff to easily hang IV bottles on it. A linkage wedge presses against a rotating plate, which in turn pushes a retaining plate to stably hold and easily release the IV bottle, thus assisting the IV chair in the infusion process.

[0019] The invention can also move the push plate simultaneously through the support block. Under the pressure of the push plate, the foot support pad extends, providing support for drowsy children while also supporting the child's legs, making the infusion process more comfortable and pleasant for the child.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] An infusion chair used in pediatric outpatient clinics, such as Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the device includes an infusion chair 1, a leaning component, a buckle component, and an IV bag assembly. The infusion chair 1 is the main carrier for infusion, consisting of the basic chair components: a support leg, armrests, and a backrest. The backrest has two through openings through which the leaning component is slidably connected. The leaning component provides safe support for children who become drowsy during infusion. The leaning component is activated by sliding back and forth through the openings in the backrest. The leaning part of the leaning component has a buckle component that locks into the leaning component, limiting its position and ensuring stable support. An IV bag assembly is located on one side of the infusion chair 1. This assembly is used to hang the IV bag and can be raised and lowered to facilitate hanging the IV bag for medical staff, thus assisting with the infusion process.

[0034] like Figure 4 and Figure 5 As shown, the support assembly includes a support block 21, a flip block 22, a retaining plate 23, a limiting frame 24, and a limiting rod 25. The backrest of the infusion chair 1 is slidably connected to the support block 21 for children to lean against via an opening. There are two support blocks 21, left and right, each with a flip block 22 rotatably connected to its rear end. The two flip blocks 22 are connected by a retaining plate 23 located at the rear ends of the two flip blocks 22. A retaining plate 23 is fixedly attached to the back of the infusion chair 1 to limit the flip blocks. The limiting frame 24 of 22 has a recessed slot. The limiting frame 24 has a limiting rod 25 that slides through the slot. When the flip block 22 rotates downward into the slot, the limiting rod 25 is lowered, locking the flip block 22 in the limiting frame 24. This reduces the space occupied by the flip block 22 protruding outward after the support block 21 is retracted into the infusion chair 1. At the same time, it can lock the support component when not in use to prevent it from affecting the normal use of the infusion chair 1.

[0035] like Figure 5 As shown, the latching assembly includes a lever 31 and a first spring 32. The connection between the support block 21 and the flip block 22 is provided with a lever 31 for latching. There are two levers 31, and the first spring 32 is elastically connected between the two levers. The levers are slidably connected to the upper surface of the flip block 22. The lever 31 consists of a latch and a lever. When the latch is latched in the opening on the support block 21, it horizontally restricts the support block 21 and the flip block 22. After the support assembly slides backward, the lever is used to press the latch inward. After the latch overcomes the elastic force of the first spring 32 and moves away from the opening on the support block 21, the latch will no longer restrict the support block 21 and the flip block 22, and the flip block 22 can then flip, reducing the space it occupies.

[0036] When a child receives an IV infusion in an outpatient setting, this IV chair 1 can be used. First, place the IV chair 1 in a suitable infusion location. While the child is sitting in the chair, some children may become drowsy. In this case, the caregiver can carefully push the backrest block 21 out of the backrest opening using the flip block 22. At this time, the lever 31 will pop outwards under the force of the first spring 32. The lever 31 will then lock into the opening on the backrest block 21, ensuring that the backrest block 21 and the flip block 22 are pushed out horizontally. Once the backrest block 21 is pushed out to its outermost position, it can support the drowsy child's tilted body, preventing the child from falling over and pressing on the IV tubing, thus affecting the smooth progress of the infusion. When the child is awake and no longer needs to lean, the backrest block 21 and the flip block 22 can be manually pulled back. When pulled back to its original position, the front end of the backrest block 21 will be flush with the back of the infusion chair 1. At this time, the flip block 22 will occupy a large space on the back of the infusion chair 1. At this time, the actuating clip 31 can be squeezed inward to overcome the elastic force of the first spring 32 and disengage from the opening on the backrest block 21. After disengagement, the actuating clip 31 will no longer restrict the backrest block 21 and the flip block 22 to the same level. At this time, the flip block 22 can be rotated towards the ground. When the flip block 22 is rotated to be perpendicular to the backrest block 21, the clip 23 will enter the opening of the limiting frame 24. When the limiting rod 25 is inserted into the limiting frame 24, the unused backrest block 21 and the flip block 22 can be restricted. At the same time, the flip block 22 is folded behind the backrest, thus saving the space occupied by the infusion chair 1.

[0037] like Figure 2 and Figure 6 As shown, the infusion assembly includes a support rod 41, a motor 42, a bidirectional threaded rod 43, and an infusion rack 44. A vertical support rod 41 is connected to one side of the infusion chair 1. A motor 42 is installed at the upper end of the support rod 41. The output shaft of the motor 42 is located inside the support rod 41. The bidirectional threaded rod 43 is connected to the internal rotation of the support rod 41. The bidirectional threaded rod 43 is connected to the output shaft of the motor 42. The upper end of the support rod 41 is slidably connected to the infusion rack 44. The infusion rack 44 is composed of multiple outwardly radiating perforated plates. The bidirectional threaded rod 43 meshes with the infusion rack 44 through threads. When the bidirectional threaded rod 43 rotates, the threads drive the infusion rack 44 to rise and fall.

[0038] like Figure 6 and Figure 7As shown, it also includes clamping components. Each perforated plate on the IV rack 44 is equipped with a clamping component. The clamping components can further clamp the IV bottle placed on the IV rack 44 to prevent the IV bottle from falling after being hung up. The clamping components include an elastic frame 51, a linkage wedge 52, a clamping plate 53, a linkage rotating plate 54, and a second spring 55. Each perforated plate on the IV rack 44 is provided with multiple grooves, through which the elastic frame 51 is slidably connected. The elastic frame 51 is slidably connected to... The upper side of the perforated plate of the IV rack 44 is slidably connected to the clamping plate 53 via grooves, and the clamping plate 53 is symmetrically arranged at the clamping opening of the perforated plate. The IV rack 44 is connected to the linkage rotating plate 54 via a rotating rod. When the linkage wedge 52 is squeezed by the IV bottle, it will squeeze the linkage rotating plate 54 to rotate. The linkage rotating plate 54 and the IV rack 44 are elastically connected to the second spring 55 for reset. After the linkage rotating plate 54 rotates, it can squeeze and push the clamping plate 53 inward to stably clamp the IV bottle.

[0039] When a nurse administers an IV to a child, pressing the control button on support rod 41 starts motor 42. Motor 42 rotates forward, driving bidirectional threaded rod 43 to rotate. This rotation of bidirectional threaded rod 43 causes the IV rack 44 to descend on support rod 41. Once it reaches a suitable height, the nurse can easily place the IV bottle onto the rack 44. When the bottle neck is placed on the rack 44, it is first pressed against the inclined surface of linkage wedge 52. The pressure from the inclined surface forces linkage wedge 52 to move. After linkage wedge 52 moves open, the IV bottle neck enters the perforated plate of the rack 44. The perforations in the plate limit the movement of the IV bottle neck. Pushing the linkage wedge further... Squeezing the linkage plate 54 causes it to rotate. The linkage plate 54 rotates after overcoming the elastic force of the second spring 55. The rotated linkage plate 54 pushes the clamping plate 53 inward, while firmly clamping the infusion bottle to prevent it from falling out of the IV rack 44. Pressing the control button starts the motor 42 and rotates in the opposite direction, which drives the bidirectional threaded rod 43 to reverse, thereby raising the IV rack 44, which holds the infusion bottle, back to the infusion height. After the infusion is finished, pushing the elastic frame 51 will push the linkage wedge 52 outward with elastic force. At the same time, the elastic frame 51 will also squeeze open the clamping plate 53 to remove the infusion bottle.

[0040] Example 2:

[0041] Based on Example 1, such as Figure 5As shown, it also includes an adjustment assembly, which includes an adjustment threaded rod 61, a push wedge 62, an elastic pad 63, and a third spring 64. Both the leaning block 21 and the flipping block 22 have through holes. The adjustment threaded rod 61 is rotatably connected to the leaning block 21 and the flipping block 22 through the through holes. The push wedge 62 is slidably connected inside the leaning block 21. The third spring 64 is elastically connected between the push wedge 62 and the leaning block 21. The push wedge 62 is connected to the elastic pad 63. After the adjustment threaded rod 61 is screwed into the leaning block 21, it will press against the inclined surface of the push wedge 62. The push wedge 62 pushes the elastic pad 63 to move towards the side where the child is leaning, so that the elastic pad 63 can extend and retract as needed to meet the different leaning needs of the child.

[0042] like Figure 1 and Figure 10 As shown, it also includes a footrest assembly, which includes a linkage rod 81, a push-out plate 82, and a footrest pad 83. The linkage rod 81 is fixedly connected to the lower side of one of the support blocks 21, and the lower end of the linkage rod 81 is provided with a push-out plate 82. The footrest pad 83 is slidably connected to the lower side of the seat cushion of the infusion chair 1. The front end of the push-out plate 82 contacts the footrest pad 83. When the support block 21 is pushed out for use, it will drive the footrest pad 83 to slide out of the seat cushion of the infusion chair 1. The footrest pad 83 can support the child's feet when sitting on the infusion chair 1, so that when the child is dozing off, his feet are supported and lifted by the footrest pad 83, improving the child's comfort during infusion.

[0043] When children of different ages are receiving intravenous infusions while sitting on the infusion chair 1, the adjusting screw 61 can be turned to adjust the child's position based on whether the child is leaning against it while drowsy. The screw 61 engages with the screw of the flipping block 22, causing it to move forward within the flipping block 22. When it reaches the leaning block 21, it will press against the pushing wedge 62. This pressing force overcomes the elasticity of the third spring 64, causing the elastic pad 63 to be pushed inward, thus providing better support for the leaning child. When it is necessary to retract the leaning block 21, the adjusting screw 61 can be turned in the opposite direction. After the threaded rod 61 is turned back into place, the push wedge 62, no longer under pressure, will drive the elastic pad 63 to reset under the elastic force of the third spring 64. Thus, the elastic pad 63 returns to its original position and no longer obstructs the reset of the backrest block 21. When the backrest block 21 is pushed out from the backrest for the child to lean on, the backrest block 21 will also drive the linkage rod 81 to move forward. The forward-moving linkage rod 81 will push the push plate 82 to move forward. The push plate 82 will drive the footrest pad 83 to move forward and extend from under the seat cushion of the infusion chair 1, effectively supporting the legs of the child sleeping during infusion and improving the comfort of the child during infusion.

[0044] Example 3: Based on Example 2, such as Figure 8 and Figure 9 As shown, it also includes a collection assembly, which includes a placement plate 71, a collection box 72, a box cover 73, and a filter screen 74. The placement plate 71 is provided on one side of the seat of the infusion chair 1. The placement plate 71 is provided with a collection box 72 for placing the infusion bottle after the infusion is completed. The box cover 73 is provided at the upper opening of the collection box 72. The filter screen 74 is provided inside the collection box 72. The filter screen 74 can filter out the residual medicine after the infusion bottle is poured out, so as to separate the infusion bottle and the residual medicine and improve the efficiency of subsequent processing of the infusion bottle.

[0045] like Figure 1 and Figure 2 As shown, it also includes a storage component, which includes a storage frame 91. The storage frame 91 is provided on the armrest of the infusion chair 1. The storage frame 91 can be used to place objects that children use for entertainment during infusion, thereby effectively diverting children's attention during infusion and preventing children from crying during infusion.

[0046] After the IV bottle is finished and removed, the nurse opens the box lid 73 and places the empty bottle into the collection box 72. The bottle will fall onto the filter 74. Some medication residue will inevitably remain in the bottle; this residue will flow out of the bottle and be filtered down to the bottom of the collection box 72, separating the medication from the bottle. This allows cleaning staff to easily remove the collection box 72 from the placement plate 71, remove the bottle from the filter 74, and recycle it. Finally, the filtered medication at the bottom of the collection box 72 is safely disposed of. During a child's IV infusion, play items can be placed in the storage compartment 91. These items can alleviate discomfort and anxiety, attract the child's attention, and make the infusion process more relaxed and enjoyable.

[0047] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
