Description

Technical Field

[0001] This invention belongs to the field of intravenous infusion technology, specifically relating to a device for preventing and fixing intravenous infusion. Background Technology

[0002] Intravenous therapy is a common treatment method that uses atmospheric pressure and hydrostatic pressure to deliver large amounts of sterile fluids, electrolytes, and medications into the body via a vein. During infusion, needles are usually inserted into the wrist, back of the hand, elbow, or instep. However, in actual treatment, because the blood vessels of some younger children are thinner and harder to find, it makes needle insertion more difficult. In such cases, infusion is usually performed in the child's head.

[0003] When administering intravenous infusion to a young child's head, the child is often restless and uncooperative, and may grab the dangling IV tubing with their hands, causing the needle to detach from the head and resulting in unnecessary pain for the child.

[0004] Therefore, a fixation device for preventing intravenous treatment loss was designed to solve the above problems. Summary of the Invention

[0017] As a preferred embodiment of the intravenous treatment anti-loosening fixation device of the present invention, the rectangular frame is symmetrically fixedly connected with blocks, and two blocks are rotatably connected to a rotating cylinder through a third rotating shaft. The rotating cylinder is equidistantly fitted with multiple limiting discs on its surface, and the limiting discs and the rotating cylinder are fixedly connected.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This intravenous infusion treatment anti-dislodgement fixation device, when used, first connect the infusion tubing to various points on the device, and then place the head loop with the connected infusion tubing over the child's head and fix it in place. Next, connect the needle at one end of the infusion tubing to the vein in the child's head, and the other end to the IV bag. At this point, leave a certain length of the infusion tubing according to the child's pulling range. The infusion tubing is then positioned between the first and second arc-shaped sleeves. The second arc-shaped sleeve, with the cooperation of the limiting slide rod and the second spring, can clamp the infusion tubing, preventing it from moving under its own weight. Intravenous infusion treatment can then be administered to the child. When a child pulls on the dangling IV tubing, the movement of the tubing causes the hollow block to move through the T-shaped block within the rectangular frame. When the child's pulling force is strong, the hollow block overcomes the elastic force of the first spring and continues to move downwards. When it reaches a certain position, the plug moves within the clamping frame with the help of the limiting slider. The movement of the plug pushes the IV tubing into the arc-shaped groove, causing the IV tubing within the clamping frame to bend. This prevents the IV tubing from moving further downwards and avoids it from overcoming the holding force between the first and second arc-shaped sleeves. This effectively prevents the needle from detaching from the child's head and ensures the smooth progress of the IV infusion process.

[0020] 2. When using this intravenous therapy anti-detachment fixation device, first place the headband on the child's head and adjust its position. Then, while keeping the headband in place, continuously squeeze and press the air bladder. The air bladder draws in outside air through the second one-way valve and is then delivered to the annular air bladder through the air delivery tube, causing the annular air bladder and the bladder protrusion to inflate until the bladder protrusion fits snugly against the child's head. At this point, stop squeezing and pressing the air bladder to complete the fixation of the headband. After the infusion is finished, open the sealing plug on the surface of the exhaust pipe. The gas inside the annular air bladder and the bladder protrusion will leak out, and the annular air bladder and the bladder protrusion will gradually flatten. Then, the headband can be removed from the child's head.

[0021] 3. This intravenous therapy anti-dislodgement fixation device, when a child pulls on the dangling infusion tube, the movement of the infusion tube will cause the hollow block to move through the T-shaped block within the rectangular frame. The movement of the hollow block will then cause the pressure rods on both sides to move accordingly. At this time, the third spring is in a compressed state. When the pulling force is large, the hollow block continues to move downward until the pressure rod is located outside the limiting groove. At this time, the elastic force of the third spring causes the limiting round block to move within the hollow block through the cooperation of the limiting block, which in turn causes the pressure rod to be inserted into the limiting groove, thereby limiting the movement position of the hollow block. When it is necessary to release the limitation of the hollow block, the user can insert the cylindrical rods on both sides into the limiting grooves on both sides respectively, and then press the cylindrical rods simultaneously to move the pressure rod out of the limiting groove. At this time, the hollow block can move upward under the elastic force of the first spring.

[0022] 4. When the hollow block is positioned, the first conductive block and the second conductive block come into contact, and the circuit is connected. At this time, the alarm sounds, which can remind medical staff and guardians to stop the child's behavior.

[0023] 5. In this intravenous therapy anti-dislodgement fixation device, when the hollow block is positioned, it presses against the contact rod, causing the contact rod to move downwards. The movement of the contact rod then moves the fixing block, which in turn moves the rack within the rectangular frame. Simultaneously, the movement of the fixing block presses against the telescopic rod and the fourth spring. The movement of the rack then drives the gear to rotate, which in turn drives the first screw to rotate. The rotation of the first screw then drives the plug to move, thereby pushing the infusion tube into the arc-shaped groove. When the restriction on the hollow block is released, the fixing block moves upwards under the elastic force of the fourth spring. The movement of the fixing block then drives the rack to move, which in turn drives the gear to rotate, thereby releasing the restriction on the infusion tube. At this time, the hollow block moves the infusion tube back to its initial position.

[0024] 6. When installing the infusion tube, the infusion tube is placed between two blocks and a rectangular frame. During placement, the two blocks are pushed, and the rotating rod rotates in the U-shaped seat. At this time, the torsion spring is in a stored state. When the infusion tube is placed between the blocks and the rectangular frame, the blocks return to their initial state under the torsion of the torsion spring, thus limiting the swing amplitude of the infusion tube.

[0025] 7. This intravenous therapy anti-dislodgement fixation device wraps the infusion tube around the surface of the rotating cylinder and passes the infusion tube through the limiting cylinder, which can fix the reserved part of the infusion tube and prevent the infusion tube from falling on the child's head and causing discomfort to the child.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] See Figure 1-11 The present invention provides a technical solution: a fixation device for preventing detachment during intravenous treatment, comprising a head ring 1, a rectangular frame 2 and a connecting post 3, wherein the connecting post 3 is fixedly connected to the surface of the head ring 1, and the rectangular frame 2 is fixedly connected to the surface of the connecting post 3.

[0049] A movable component 5 is provided on the inner wall of the rectangular frame 2. The movable component 5 includes a T-shaped block 53 inserted into the inner wall of the rectangular frame 2 and a hollow block 52 fixedly connected to the surface of the T-shaped block 53. The T-shaped block 53 and the rectangular frame 2 are slidably connected. A first spring 51 is fixedly connected between the hollow block 52 and the rectangular frame 2. A positioning ring 58 is fixedly connected to the surface of the hollow block 52. A first arc-shaped sleeve 512 is fixedly connected to one side of the inner wall of the positioning ring 58. Two limiting slide rods 511 are symmetrically inserted on the side of the positioning ring 58 away from the first arc-shaped sleeve 512. The limiting slide rods 511 are slidably connected to the positioning ring 58. One end of the limiting slide rod 511 extends into the interior of the positioning ring 58 and is fixedly connected to a second arc-shaped sleeve 59 provided inside the positioning ring 58. A second spring 510 is fixedly connected between the second arc-shaped sleeve 59 and the positioning ring 58.

[0050] The bottom surface of the rectangular frame 2 is provided with a limiting clamping component 7. The limiting clamping component 7 includes a clamping frame 711 fixedly connected to the bottom surface of the rectangular frame 2, a plug 78 inserted into the clamping frame 711, and an arc-shaped groove 79 opened inside the clamping frame 711. The plug 78 and the clamping frame 711 are slidably connected. A limiting slider 710 is symmetrically fixedly connected to the surface of the plug 78. The limiting slider 710 is inserted into the clamping frame 711, and the limiting slider 710 and the clamping frame 711 are slidably connected.

[0051] In this implementation plan: When using this device, firstly, connect the infusion tubing to various points on the device, and then place and secure the head loop 1 with the connected infusion tubing on the child's head. Next, connect the needle at one end of the infusion tubing to a vein in the child's head, and the other end to the IV bag. At this point, leave a certain length of the infusion tubing according to the child's pulling range. The infusion tubing is then positioned between the first arc-shaped sleeve 512 and the second arc-shaped sleeve 59. The second arc-shaped sleeve 59, under the combined action of the limiting slide rod 511 and the second spring 510, can clamp the infusion tubing, preventing it from moving under its own weight. Then, intravenous infusion treatment can be administered to the child. When the child pulls on the dangling infusion tubing... During infusion, the movement of the infusion tube will cause the hollow block 52 to move within the rectangular frame 2 via the T-shaped block 53. When the child's pulling force is large, the hollow block 52 will continue to move downwards against the elastic force of the first spring 51. When it moves to a certain position, the plug 78 will move within the clamping frame 711 with the cooperation of the limiting slider 710. The movement of the plug 78 will push the infusion tube into the arc-shaped groove 79, causing the infusion tube located within the clamping frame 711 to bend. This will prevent the infusion tube from moving further downwards and avoid the infusion tube from continuing to move downwards against the holding force between the first arc-shaped sleeve 512 and the second arc-shaped sleeve 59. This can effectively prevent the needle from detaching from the child's head and ensure the smooth progress of the infusion process.

[0052] It should be noted that the first arc-shaped sleeve 512 and the second arc-shaped sleeve 59 are provided with anti-slip rubber protrusions on their close sides, which can increase the friction between them and the infusion tube, thereby achieving the limiting and fixing of the infusion tube.

[0053] Example 2

[0054] This embodiment is a further improvement on embodiment 1. Please refer to [link / reference]. Figure 1-11 The headband 1 is internally equipped with a reinforcing component 4. The reinforcing component 4 includes an annular airbag 41 fixedly connected to the inner wall of the headband 1, an airbag protrusion 42 fixedly connected to the surface of the annular airbag 41, and an air supply pipe 43 fixedly connected to the surface of the annular airbag 41. The annular airbag 41 and the airbag protrusion 42 are connected to each other, and the annular airbag 41 and the air supply pipe 43 are connected to each other. The air supply pipe 43 is inserted into the surface of the headband 1 and fixedly connected to the headband 1. A first one-way valve 46 is fixedly connected inside the air supply pipe 43. A press airbag 44 is fixedly connected to one end of the air supply pipe 43. A second one-way valve 45 is fixedly connected to the surface of the press airbag 44. An exhaust pipe 47 is fixedly connected to the surface of the annular airbag 41.

[0055] In this implementation plan: When using the device, first place the headband 1 on the child's head and adjust its position. Then, while keeping the headband 1 in the same position, continuously squeeze and press the airbag 44. The airbag 44 draws in outside air through the second one-way valve 45 and then delivers it to the annular airbag 41 through the air delivery tube 43. This causes the annular airbag 41 and the airbag protrusion 42 to inflate until the airbag protrusion 42 fits against the child's head. At this point, stop squeezing and pressing the airbag 44 to secure the headband 1. After the infusion is finished, open the sealing plug on the surface of the exhaust pipe 47. The gas inside the annular airbag 41 and the airbag protrusion 42 leaks out, and the annular airbag 41 and the airbag protrusion 42 gradually flatten. Then, the headband 1 can be removed from the child's head.

[0056] It should be noted that a sealing plug is provided at the end of the exhaust pipe 47.

[0057] Example 3

[0058] This embodiment is a further improvement on embodiment 1. Please refer to [link / reference]. Figure 1-11 Two limiting circular blocks 54 are symmetrically inserted inside the hollow block 52. The limiting circular blocks 54 and the hollow block 52 are slidably connected. A rectangular limiting block 55 is symmetrically fixedly connected to the surface of the limiting circular block 54. The rectangular limiting block 55 is inserted inside the hollow block 52. The rectangular limiting block 55 and the hollow block 52 are slidably connected. A pressing rod 57 is fixedly connected to the surface of the limiting circular block 54. A third spring 56 is fixedly connected between the limiting circular block 54 and the hollow block 52. Two limiting grooves 515 that cooperate with the pressing rod 57 are symmetrically opened on the surface of the rectangular frame 2.

[0059] In an optional embodiment, a connecting rope 513 is symmetrically fixedly connected to the surface of the rectangular frame 2 at a position below the limiting groove 515, and a cylindrical rod 514 is fixedly connected to one end of the connecting rope 513.

[0060] In this implementation scheme: When a child pulls on the dangling IV tubing, the movement of the tubing will cause the hollow block 52 to move through the T-shaped block 53 within the rectangular frame 2. The movement of the hollow block 52 will then cause the pressure rods 57 on both sides to move accordingly. At this time, the third spring 56 is in a compressed state. When the pulling force is large, the hollow block 52 continues to move downward until the pressure rod 57 is located outside the limiting groove 515. At this time, the elastic force of the third spring 56 will cause the limiting block 54 to pass through the rectangular frame 2. The positioning block 55 moves within the hollow block 52, thereby driving the pressing rod 57 to insert into the limiting groove 515, thus limiting the movement position of the hollow block 52. When it is necessary to release the limitation on the hollow block 52, the user can insert the cylindrical rods 514 on both sides into the limiting grooves 515 on both sides respectively, and then press the cylindrical rods 514 at the same time to move the pressing rod 57 out of the limiting groove 515. At this time, the hollow block 52 can move upward under the elastic force of the first spring 51.

[0061] It should be noted that there are two cylindrical rods 514, located on both sides of the rectangular frame 2 respectively, and one end of the pressing rod 57 is provided with a ball head, which makes it easy to insert into the limiting groove 515.

The alarm component 6 includes an alarm 61 and a battery 62 fixedly connected to the surface of the rectangular frame 2. A first conductive block 63 is fixedly connected to the bottom surface of the hollow block 52. A second conductive block 64 is fixedly connected to the inner wall of the rectangular frame 2 at a position below the limiting groove 515.

[0064] In this implementation scheme: when the position of the hollow block 52 is defined, the first conductive block 63 and the second conductive block 64 come into contact, the circuit is connected, and the alarm 61 sounds an alarm, thereby reminding medical staff and guardians to stop the child's behavior.

[0065] Example 5

[0066] This embodiment is a further improvement on embodiment 1. Please refer to [link / reference]. Figure 1-11 A rack 71 is inserted into the inner wall of the rectangular frame 2, and the rack 71 is slidably connected to the rectangular frame 2. A fixing block 72 is fixedly connected to the surface of the rack 71. The fixing block 72 is inserted into the inner wall of the rectangular frame 2 and is slidably connected to the rectangular frame 2. A contact rod 73 is fixedly connected to the surface of the fixing block 72. A first screw 77 is inserted into the surface of the plug 78, and the first screw 77 is threadedly connected to the plug 78. The first screw 77 is inserted into the surface of the rectangular frame 2 and is rotatably connected to the rectangular frame 2 through a first bearing. One end of the first screw 77 extends to the outside of the rectangular frame 2 and is fixedly connected to a gear 76 located on the outside of the rectangular frame 2. The gear 76 and the rack 71 are meshed together.

[0067] In an optional embodiment, a telescopic rod 74 and a fourth spring 75 are fixedly connected between the fixed block 72 and the rectangular frame 2, with the fourth spring 75 sleeved on the surface of the telescopic rod 74.

[0068] In this implementation scheme: When the position of the hollow block 52 is restricted, the hollow block 52 presses the contact rod 73, causing the contact rod 73 to move downward. The movement of the contact rod 73 then drives the fixed block 72 to move. The movement of the fixed block 72 then drives the rack 71 to move within the rectangular frame 2. At the same time, the movement of the fixed block 72 presses the telescopic rod 74 and the fourth spring 75. The movement of the rack 71 then drives the gear 76 to rotate. The rotation of the gear 76 then drives the first screw 77 to rotate. The rotation of the first screw 77 then drives the plug 78 to move, thereby pushing the infusion tube into the arc-shaped groove 79. When the restriction on the hollow block 52 is released, the fixed block 72 moves upward under the elastic force of the fourth spring 75. The movement of the fixed block 72 then drives the rack 71 to move. The movement of the rack 71 then drives the gear 76 to rotate, thereby releasing the restriction on the infusion tube. At this time, the hollow block 52 drives the infusion tube to return to its initial position.

A stop bar 83 is fixedly connected to the surface of the U-shaped seat 82. A torsion spring 85 is fixedly connected between the rotating rod 84 and the stop bar 83.

[0071] In this implementation scheme: When installing the infusion tube, the infusion tube is placed between two stops 86 and the rectangular frame 2. During placement, the two stops 86 are pushed, and the rotating rod 84 rotates within the U-shaped seat 82. At this time, the torsion spring 85 is in a stored state. When the infusion tube is placed between the stops 86 and the rectangular frame 2, the stops 86 return to their initial state under the torsion of the torsion spring 85, thus limiting the swing amplitude of the infusion tube.

[0072] It should be noted that: the bottom end of the rotating rod 84 is fixedly connected to a turntable, one end of the torsion spring 85 is fixedly connected to the turntable, and the other end of the torsion spring 85 is connected to the stop rod 83.

[0075] In an optional embodiment, a block 93 is symmetrically fixedly connected to the surface of the rectangular frame 2, and a rotating cylinder 94 is rotatably connected between two blocks 93 through a third rotating shaft. A plurality of limiting discs 95 are equidistantly sleeved on the surface of the rotating cylinder 94, and the limiting discs 95 and the rotating cylinder 94 are fixedly connected.

[0076] In this implementation plan: the infusion tube is wrapped around the surface of the rotating cylinder 94 and passed through the limiting cylinder 92, which can secure the reserved part of the infusion tube and prevent the infusion tube from falling on the child's head and causing discomfort to the child.

[0077] Working principle: When using this device, first connect the infusion tubing to each position on the device, and then place the head ring 1 (with the infusion tubing connected) on the child's head. Adjust the position of the head ring 1, and then, while keeping the head ring 1 in place, continuously squeeze and press the air bladder 44. The air bladder 44 draws in outside air through the second one-way valve 45, and then delivers it to the annular air bladder 41 through the air inlet tube 43, causing the annular air bladder 41 and the air bladder protrusion 42 to inflate until the air bladder protrusion 42 fits against the child's head. At this point, stop squeezing and pressing the air bladder 44, thus securing the head ring 1. Next, wrap the infusion tubing around the surface of the rotating cylinder 94 and pass the infusion tubing through the limiting cylinder 92. This secures the reserved portion of the infusion tubing, preventing it from scattering onto the child. To prevent discomfort to the child, the IV tubing is placed between two stops 86 and the rectangular frame 2. During placement, pushing the two stops 86 causes the rotating rod 84 to rotate within the U-shaped seat 82. At this time, the torsion spring 85 is in a charged state. When the IV tubing is placed between the stops 86 and the rectangular frame 2, the stops 86 return to their initial state under the torque of the torsion spring 85, thus limiting the swing amplitude of the IV tubing. At this point, based on the child's pulling range, a certain length of the IV tubing is reserved, and the IV tubing is placed between the first arc-shaped sleeve 512 and the second arc-shaped sleeve 59. The second arc-shaped sleeve 59, in conjunction with the limiting slide rod 511 and the second spring 510, can clamp the IV tubing, preventing it from moving under its own weight. Once ready, Connect the needle at one end of the infusion tube to the vein in the child's head, and the other end to the IV bag for intravenous infusion. The movement of the infusion tube will cause the hollow block 52 to move within the rectangular frame 2 via the T-block 53. The movement of the hollow block 52 then moves the pressure rods 57 on both sides. At this time, the third spring 56 is compressed. When the pulling force is large, the hollow block 52 continues to move downwards until the pressure rod 57 is located outside the limiting groove 515. Then, the elastic force of the third spring 56 causes the limiting block 54 to move within the hollow block 52 through the cooperation of the rectangular limiting block 55, thereby causing the pressure rod 57 to insert into the limiting groove 515, thus limiting the movement position of the hollow block 52. At this time, the first conductive block 63 and the second conductive block 6... When all four phases are in contact, the circuit is connected, and the alarm 61 sounds, alerting medical staff and guardians to stop the child's behavior. During this process, the hollow block 52 presses against the contact rod 73, causing it to move downwards. This movement of the contact rod 73 then moves the fixing block 72, which in turn moves the rack 71 within the rectangular frame 2. Simultaneously, the moving fixing block 72 presses against the telescopic rod 74 and the fourth spring 75. The rack 71 then moves, causing the gear 76 to rotate. The rotation of the gear 76 then rotates the first screw 77, which in turn moves the plug 78, pushing the IV tubing into the arc-shaped groove 79, causing the IV tubing within the clamping frame 711 to bend.This prevents the infusion tube from moving further downwards, avoiding the infusion tube overcoming the clamping force between the first arc-shaped sleeve 512 and the second arc-shaped sleeve 59 to continue moving downwards. It effectively prevents the needle from detaching from the child's head, ensuring the smooth progress of the infusion process. When it is necessary to release the restriction on the hollow block 52, the user can insert the cylindrical rods 514 on both sides into the limiting grooves 515 on both sides, and then press the cylindrical rods 514 simultaneously to move the pressing rod 57 out of the limiting groove 515. At this time, the hollow block 52 can move upwards under the elastic force of the first spring 51. When the restriction on the hollow block is released... When the limit of 52 is reached, the fixing block 72 moves upward under the elastic force of the fourth spring 75. The movement of the fixing block 72 then drives the rack 71 to move, and the movement of the rack 71 then drives the gear 76 to rotate, thereby releasing the limit on the infusion tube. At this time, the hollow block 52 drives the infusion tube to return to its initial position. After the infusion is completed, the needle is pulled out from the child's head, and the sealing plug on the surface of the exhaust pipe 47 is opened. The gas in the annular airbag 41 and the airbag protrusion 42 leaks out, and the annular airbag 41 and the airbag protrusion 42 gradually flatten. Then the headband 1 can be removed from the child's head.
