Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of nursing infusion devices, and more specifically, relates to a pediatric nursing infusion device that prevents the needle from slipping out due to struggle. Background Technology
[0002] Intravenous infusion in pediatrics refers to intravenous infusion procedures performed on children in pediatric clinical nursing. It is a common intervention method used in pediatric clinical settings such as administering medication for infectious diseases, rehydration for dehydration, and postoperative nutritional support. This procedure is performed by professional medical staff who perform intravenous puncture and insert an infusion needle to infuse medication, nutritional solutions, or electrolyte solutions into the child through the infusion line to achieve the nursing goals of disease treatment and regulation of bodily functions. Because children are not yet fully developed physiologically and psychologically, they are naturally active and easily develop a fear of infusion needles, which may lead to crying, struggling, and other behaviors during the infusion process.
[0003] Chinese patent publication number CN106964018A discloses a medical infusion stand for children. This invention features an infusion stand equipped with music-playing colored lights that automatically play music and emit dazzling lights to attract the baby's attention. When playing lullabies, it can soothe the baby to sleep, facilitating medical treatment. By installing casters at the bottom of the device, it becomes movable, making it convenient to use. Furthermore, when the baby becomes agitated, the seat can be moved by pushing a handle, allowing the baby to be carried around.
[0004] Existing anti-dislodgement devices for intravenous infusion in children have the following drawbacks:
[0005] 1. Existing anti-dislodgement devices for intravenous infusion in children generally adopt a strap-type structure. This method aims to prevent needle dislodgement by directly binding and fixing the child's hands to a fixed carrier such as the armrest of the infusion chair or the table. This is a typical restraint-type fixation method, which restricts the child's limb movement and causes obvious discomfort such as a feeling of restraint and pressure. This may further aggravate the child's crying and violent struggle, which in turn increases the risk of needle dislodgement and damage to the puncture site.
[0006] 2. Existing anti-escape devices lack flexibility in their fixation methods and are relatively simple in general. Once the fixation strength and state are set, they cannot be dynamically adjusted according to the child's real-time state. During pediatric intravenous infusion, the child's hands are continuously and forcibly restrained regardless of whether the child is in a quiet and cooperative state or crying and struggling. When the child cries and struggles, the fixation strength cannot be increased in time; while when the child remains quiet, the continuous forcible restraint is excessive and increases the child's physical discomfort.
[0007] In view of this, we have studied and improved the existing structure and its shortcomings, and provided a pediatric nursing infusion device that prevents the needle from slipping out of the needle, in order to achieve a more practical purpose. Summary of the Invention
[0008] To address the aforementioned technical problems, this invention provides a pediatric nursing infusion device that prevents needle dislodgement due to struggle.
[0009] A pediatric infusion device for preventing needle dislodgement during infusion includes a fixed wristband with a protective mechanism to prevent dislodgement. The protective mechanism includes a cylindrical box, a palm wristband, a miniature air pump, and connecting straps. The cylindrical box is located at the side end of the fixed wristband, and the fixed wristband and palm wristband are connected by two connecting straps. The cylindrical box is fixedly installed at the circumferential end of the fixed wristband. The miniature air pump is located at the side end of the palm wristband. The fixed wristband has a first strap, and multiple rubber protrusions are fixedly installed at the circumferential end of the inner wall of the fixed wristband. The rubber bumps are arranged in an array. A gyroscope sensor is provided on the inner wall of the cylindrical box. A first sealing gasket is fitted on the upper end of the cylindrical box. A fixed cover plate is fixedly installed on the upper end of the first sealing gasket. A dial is fixedly installed on the upper end of the fixed cover plate. A second strap is provided on the palm wristband. An annular plate is fixedly installed on the palm wristband. A skin-friendly rubber layer is fixedly installed on the lower end of the annular plate. An airbag is provided on the inner wall of the skin-friendly rubber layer. A fixed circular plate is fitted on the upper end of the annular plate. A cartoon cover plate is fixedly installed on the upper end of the fixed circular plate.
[0010] Preferably, the micro air pump is fixedly installed at the circumferential end of the annular plate, and the output end of the micro air pump is located inside the airbag.
[0011] Preferably, a data transmission line is fixedly installed between the miniature air pump and the gyroscope sensor, and a protective tube is provided between the annular plate and the cylindrical box, the protective tube being sleeved on the outer wall of the miniature air pump and the data transmission line.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, a cartoon cover and a ring plate are used together. The cartoon cover is placed on the upper part of the ring plate corresponding to the injection site, effectively covering the injection site during intravenous infusion in children. This prevents children from directly seeing the needle, reducing the visual impact of the needle and alleviating children's fear of intravenous infusion. Children are prone to an instinctive fear of needles, and the covering design can reduce crying and struggling behaviors caused by fear, improving children's cooperation during intravenous infusion and meeting the psychological care needs of children in pediatric intravenous infusion.
[0014] In this invention, a fixed wristband and a palm wristband are provided, which are connected by a connecting strap. During the infusion process in children, the device is fixed only to the child's wrist and palm, without forcibly binding the child's hands to fixed objects such as chairs or tables. This fixing method allows the child's hands to retain a certain amount of room to move, which can meet the child's basic activity needs during infusion, reduce the physical discomfort caused by excessive restraint, and reduce struggling behavior caused by discomfort. This makes the fixing method for pediatric infusion more in line with the characteristics of children's limb movement.
[0015] In this invention, a dial and a fixed cover are used to fix the dial to the upper end of the fixed cover. During the infusion process for children, the dial's design can attract children's attention and shift their focus away from the infusion needle, reducing children's attention to and touching of the injection site. This reduces the risk of needle displacement caused by touching the needle. At the same time, parents can directly observe the duration of the infusion through the dial, making it easier for them to keep track of the infusion progress and better cooperate with medical staff to complete the infusion care for children, thus improving the convenience of pediatric infusion care.
[0016] In this invention, a gyroscope sensor, a miniature air pump, and an air bladder are used in conjunction. The gyroscope sensor is positioned on the inner wall of a cylindrical box. During intravenous infusion in children, when a child shakes their hand violently due to crying or other reasons, the gyroscope sensor can quickly identify this abnormal movement and trigger the miniature air pump to inflate the air bladder via a data transmission line. The inflated air bladder gently presses a skin-friendly rubber layer against the skin around the injection site, providing protective pressure. This design replaces manual pressure to protect the needle, providing timely protection when the child struggles, preventing the needle from dislodging. The gentle pressure does not cause additional discomfort to the child's skin, making needle dislodgement prevention in pediatric intravenous infusions more timely and gentle.
[0017] This invention utilizes a gyroscope sensor, a miniature air pump, and an airbag to achieve dynamic pressure protection during pediatric intravenous infusion. The airbag's pressure function is activated only when the child cries and shakes their hand violently to protect the injection site. Once the gyroscope sensor detects that the child's hand has stopped shaking and remains stable, the miniature air pump stops inflating, and the airbag slowly deflates, ceasing pressure on the injection site and preventing continuous pressure. This dynamic design reduces discomfort caused by prolonged pressure, improves comfort during pediatric intravenous infusion, and makes needle dislodgement prevention during infusions more humane.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0028] Please see Figure 1 - Figure 8This invention provides a pediatric nursing infusion device to prevent struggle and needle dislodgement, including a fixing wristband 1. The fixing wristband 1 is equipped with a protective mechanism to prevent children from struggling during infusion. The protective mechanism includes a cylindrical box 2, a palm wristband 3, a miniature air pump 4, and connecting straps 5. The cylindrical box 2 is located at the side end of the fixing wristband 1. The fixing wristband 1 and the palm wristband 3 are connected by two connecting straps 5. The cylindrical box 2 is fixedly installed at the circumferential end of the fixing wristband 1. The miniature air pump 4 is located at the side end of the palm wristband 3. When performing nursing infusion on a child, medical staff first fix the wristband. 1. Wear the device on the child's wrist and 3. Wear the device on the child's palm. During the wearing process, adjust the position of the device so that the skin-friendly rubber layer 33 on the palm wristband 3 is accurately aligned with the child's infusion needle position. Then, adjust the first strap 11 on the fixed wristband 1 and the second strap 31 on the palm wristband 3 respectively so that the fixed wristband 1 and the palm wristband 3 are stably attached to the child's skin without loosening or shifting. After the device is worn, start the device to put it into the protective working state for pediatric infusion, providing anti-needle dislodgement protection for the subsequent infusion process.
[0029] The fixed wristband 1 is equipped with a first strap 11. Multiple rubber protrusions 12 are fixedly installed on the circumferential end of the inner wall of the fixed wristband 1. The rubber protrusions 12 are arranged in an array. A gyroscope sensor 21 is installed on the inner wall of the cylindrical box 2. A first sealing gasket 22 is fitted onto the upper end of the cylindrical box 2. A fixed cover plate 23 is fixedly installed on the upper end of the first sealing gasket 22. A dial 24 is fixedly installed on the upper end of the fixed cover plate 23. A second strap 31 is provided on the palm wristband 3. When performing intravenous infusion care for children, this device can be fixed to the limb on the side receiving the infusion. The wristband 1, with the adjustable tension of the first strap 11, can be adapted to the wrist circumference of children of different ages, thus securing the wristband 1 firmly to the child's wrist and preventing the device from slipping off during infusion. The palm wristband 3, with the adjustable tension of the second strap 31, can fit the different sizes of children's palms, securing the palm wristband 3 to the child's palm. Under the fixing effect of the palm wristband 3, the skin-friendly rubber layer 33 on it can accurately cover the injection site of the child's infusion needle, forming a physical cover for the needle tip, and building a basic protective structure for the pediatric infusion injection site.
[0030] A ring plate 32 is fixedly installed on the wristband 3. A skin-friendly rubber layer 33 is fixedly installed at the lower end of the ring plate 32. When providing intravenous infusion care to children, this device achieves auxiliary protection and anti-needle dislodgement effects through the cooperation of multiple components. The cartoon cover 36 covers the upper end of the ring plate 32 corresponding to the injection site, which can cover the injection site and prevent children from directly seeing the infusion needle, reducing children's fear of the needle and improving children's cooperation during infusion. The rubber protrusions 12 arranged in an array on the inner side wall of the fixed wristband 1 can increase the friction between the fixed wristband 1 and the child's wrist skin, preventing the device from shifting when the child moves slightly and ensuring the accuracy of the protective position. The dial 24 at the upper end of the fixed cover 23 can attract children's attention with its shape, diverting their attention from the injection site, and also making it easy for parents to visually observe the duration of infusion.
[0031] An air bladder 34 is provided on the inner wall of the skin-friendly rubber layer 33. A fixed circular plate 35 is fitted onto the upper end of the annular plate 32. A cartoon cover 36 is fixedly installed on the upper end of the fixed circular plate 35. A miniature air pump 4 is fixedly installed on the circumferential end of the annular plate 32. The output end of the miniature air pump 4 is located inside the air bladder 34. A data transmission line 41 is fixedly installed between the miniature air pump 4 and the gyroscope sensor 21. A protective tube 42 is provided between the annular plate 32 and the cylindrical box 2. The protective tube 42 is fitted onto the outer wall of the miniature air pump 4 and the data transmission line 41. When a child shakes their hand violently due to crying or other reasons during the infusion process, the gyroscope sensor 21 on the inner wall of the cylindrical box 2 will detect it in time. This abnormal movement state is detected and transmitted to the micro air pump 4 via the data transmission line 41, triggering the micro air pump 4 to start working and inflate the air bag 34. After the air is injected, the air bag 34 gradually inflates and gently adheres the skin-friendly rubber layer 33 to the skin around the injection site, providing protection for the injection site instead of manual pressing, preventing the needle from falling off due to the child's struggle during pediatric infusion. When the gyroscope sensor 21 detects that the child's hand has stopped shaking violently and has remained stable, the micro air pump 4 immediately stops inflating, and the air bag 34 slowly deflates, gradually returning to its initial fit, continuing to provide basic protection for pediatric infusion.
[0032] The dial 24 and the fixing cover 23 work together to fix the dial 24 to the upper end of the fixing cover 23. During intravenous infusion in children, the design of the dial 24 can attract children's attention and shift their focus away from the infusion needle site, reducing children's attention to and touching of the injection site, thereby reducing the risk of needle displacement caused by touching. At the same time, parents can directly observe the duration of the infusion through the dial 24, making it easier for them to keep track of the infusion progress and better cooperate with medical staff to complete the child's intravenous infusion care, thus improving pediatric care. To enhance the convenience of intravenous infusion care, the gyroscope sensor 21 works in conjunction with the miniature air pump 4 and the air bag 34. The gyroscope sensor 21 is positioned on the inner wall of the cylindrical box 2. During intravenous infusion in children, if the child shakes their hand violently due to crying or other reasons, the gyroscope sensor 21 can quickly identify this abnormal movement and trigger the miniature air pump 4 to inflate the air bag 34 via the data transmission line 41. The inflated air bag 34 then gently presses the skin-friendly rubber layer 33 against the skin around the injection site, providing protective pressure. This design replaces manual pressure to protect the needle, providing timely protection when the child struggles and preventing the needle from dislodging.
[0033] Working principle:
[0034] The first step, when performing intravenous infusion on a child, is for medical staff to first place the fixing wristband 1 on the child's wrist and the palm wristband 3 on the child's palm. During the process, the position of the device is adjusted so that the skin-friendly rubber layer 33 on the palm wristband 3 is precisely aligned with the child's infusion needle position. Then, the first strap 11 on the fixing wristband 1 and the second strap 31 on the palm wristband 3 are adjusted to ensure that both the fixing wristband 1 and the palm wristband 3 are stably fitted to the child's skin without any loosening or displacement. After the device is put on, it is activated to put the device into the protective working state for pediatric infusion, providing protection against needle dislodgement during the subsequent infusion process.
[0035] The second step involves fixing the device to the limb on the side receiving the infusion during pediatric infusion care. The wristband 1, with its adjustable tension via the first strap 11, can be adapted to the wrist circumference of children of different ages, thus securing the wristband 1 firmly to the child's wrist and preventing the device from slipping off during infusion. The palm wristband 3, with its adjustable tension via the second strap 31, can fit the different sizes of children's hands, securing the palm wristband 3 to the child's palm. Under the fixing effect of the palm wristband 3, the skin-friendly rubber layer 33 can accurately cover the injection site of the infusion needle, forming a physical cover for the needle tip and providing a basic protective structure for the pediatric infusion injection site.
[0036] This application uses a cartoon cover 36 and a ring plate 32 to cover the upper end of the ring plate 32 corresponding to the injection site. This effectively covers the injection site during intravenous infusion in children, preventing them from directly seeing the needle and reducing the visual impact of the needle. This alleviates children's fear of intravenous infusion. Children are prone to instinctive fear of needles, and the covering design can reduce crying and struggling behaviors caused by fear, improve children's cooperation during intravenous infusion, and meet the psychological care needs of children in pediatric intravenous infusion.
[0037] This application uses a fixed wristband 1 and a palm wristband 3, which are connected by a connecting strap 5. During pediatric intravenous infusion, the device is fixed only to the child's wrist and palm, without forcibly binding the child's hands to fixed objects such as chairs or tables. This fixing method allows the child's hands to retain a certain amount of room to move, which can meet the child's basic activity needs during intravenous infusion, reduce the physical discomfort caused by excessive restraint, reduce struggling behavior caused by discomfort, and make the fixing method of pediatric intravenous infusion more in line with the characteristics of children's limb movement.
[0038] Thirdly, during intravenous infusion care for children, this device utilizes multiple components to provide auxiliary protection and prevent needle dislodgement. A cartoon cover 36 covers the upper end of the annular plate 32 corresponding to the injection site, shielding the injection location and preventing children from directly seeing the needle, reducing their fear and improving their cooperation during infusion. The array of rubber protrusions 12 on the inner wall of the wristband 1 increases friction between the wristband and the child's wrist skin, preventing displacement during slight child movement and ensuring accurate positioning. The dial 24 on the upper end of the cover 23 attracts children's attention, diverting their focus from the injection site, and also allows parents to visually observe the infusion duration and progress. When a child's hand shakes violently during the infusion process due to crying or other reasons, the gyroscope sensor 21 on the inner wall of the cylindrical box 2 will detect the abnormal movement in time and transmit the detection signal to the micro air pump 4 through the data transmission line 41. This triggers the micro air pump 4 to start working and inflate the air bag 34. After the air is injected, the air bag 34 gradually inflates and gently adheres the skin-friendly rubber layer 33 to the skin around the injection site, providing protection for the injection site instead of manual pressing. This prevents the needle from falling off due to the child's struggle during the pediatric infusion. When the gyroscope sensor 21 detects that the child's hand has stopped shaking violently and has remained stable, the micro air pump 4 immediately stops inflating, and the air bag 34 slowly deflates, gradually returning to its initial fit, continuing to provide basic protection for the pediatric infusion.
[0039] This application uses a dial 24 and a fixed cover 23 to fix the dial 24 to the upper end of the fixed cover 23. During the infusion process for children, the shape of the dial 24 can attract children's attention and shift their focus away from the infusion needle, reducing children's attention to and touching of the needle site, thereby reducing the risk of needle displacement caused by touching. At the same time, parents can directly observe the duration of the infusion through the dial 24, making it easier for parents to keep track of the infusion progress and better cooperate with medical staff to complete the infusion care for children, thus improving the convenience of pediatric infusion care.
[0040] This application utilizes a gyroscope sensor 21, a miniature air pump 4, and an airbag 34 in conjunction. The gyroscope sensor 21 is positioned on the inner wall of the cylindrical box 2. During intravenous infusion in children, when a child violently shakes their hand due to crying or other reasons, the gyroscope sensor 21 quickly identifies this abnormal movement and triggers the miniature air pump 4 to inflate the airbag 34 via the data transmission line 41. The inflated airbag 34 then gently presses the skin-friendly rubber layer 33 against the skin around the injection site, providing protective pressure. This design replaces manual pressure to protect the needle, providing timely protection when the child struggles, preventing the needle from dislodging. The gentle pressure does not cause additional discomfort to the child's skin, making needle dislodgement prevention in pediatric infusions more timely and gentle.
[0041] This application utilizes a gyroscope sensor 21, a miniature air pump 4, and an airbag 34 to achieve dynamic pressure protection during pediatric intravenous infusion. The airbag 34 activates only when the child cries and shakes their hand violently to protect the injection site. Once the gyroscope sensor 21 detects that the child's hand has stopped shaking and is stable, the miniature air pump 4 stops inflating, and the airbag 34 slowly deflates, ceasing pressure on the injection site and preventing continuous pressure. This dynamic design reduces discomfort caused by prolonged pressure, improves comfort during pediatric intravenous infusion, and makes needle dislodgement prevention during infusions more humane.
