Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of children nursing, and particularly relates to an infusion fixing device for children nursing. BACKGROUND

[0002] In the field of children nursing, infusion therapy is a very common medical means, and the existing infusion fixing device for children nursing usually comprises a restraint belt and a palm support plate to reduce the risk of displacement or falling of the infusion needle.

[0003] However, due to the significant difference in individual growth and development of children, the thickness of their arms varies, but the restraint belt in the existing fixing device lacks a tightness adjustment function. This results in that, in actual use, for children with thinner arms, the too-loose restraint belt cannot effectively fix the infusion site, so that the infusion needle is prone to displacement or falling out, increasing the risk of repeated puncture; and for children with thicker arms, the restraint belt may be too tight to press the skin and hinder blood circulation, causing discomfort of the children and even local skin damage, and also causing inconvenience and trouble to the medical staff. In addition, during the infusion process, the comfortable placement and appropriate movement of the child's hands are crucial to improve the infusion experience, but the existing fixing device fails to realize the adjustment of the rotation angle of the palm support plate during infusion, and the child's hand muscles will be tired and the joints will be stiff if the child maintains the same palm posture for a long time, which will cause the child to be restless, and may lead to the child's unconscious struggle or large-scale movement of the arms. Based on the above problems, the present application proposes an infusion fixing device for children nursing to improve the above problems.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with the help of the drawings in the specification.

[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility, but the utility can also be implemented in other ways different from the description, and those skilled in the art can make similar generalization without departing from the connotation of the utility, so the utility is not limited by the specific embodiments disclosed below.

[0025] Secondly, "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility. "In a preferred embodiment" does not mean the same embodiment in different places in this specification, and is not an embodiment that is independent or optional and mutually exclusive with other embodiments.

[0026] Thirdly, the utility is described in detail in combination with the schematic diagram, in the detailed description of the utility, for the convenience of description, the sectional view showing the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the utility protection here. In addition, the three-dimensional spatial dimensions including length, width and depth should be included in actual production.

[0027] Please refer to the attached Figures 1 to 3 The utility provides a kind of infusion fixing device for child care, including fixed box 10, rotating link 11 is rotationally connected in the inside of fixed box 10, and one end of rotating link 11 penetrates the side wall of fixed box 10, ratchet 12 is fixed in the outside of rotating link 11 and located in the inside of fixed box 10, first through-hole 13 is arranged in the upper end of ratchet 12 in the inside of fixed box 10, first limiting rod 14 is slidably connected in first through-hole 13, and first limiting rod 14 and ratchet 12 are adapted, bottom plate 15 is fixed in the outside of first limiting rod 14, first spring 16 is assembled between the outside of first limiting rod 14 and bottom plate 15 and first through-hole 13, the upper end of fixed box 10 is assembled with multiple restraint belts 17, second through-hole 18 is arranged in one side of fixed box 10, one end of restraint belt 17 penetrates the inside of second through-hole 18 and is wound on the outside of rotating link 11, and the other end of restraint belt 17 is fixedly connected with the side of fixed box 10 away from second through-hole 18.

[0028] It should be noted that first spring 16 is always in compression state, and first spring 16 can drive first limiting rod 14 and bottom plate 15 to move towards the direction close to ratchet 12.

[0029] In this embodiment, when it is necessary to adjust the tightness of the restraint strap 17, the knob 19 is turned clockwise. The rotation of the knob 19 drives the rotating rod 11 to rotate, which in turn retracts the restraint strap 17, shortening the length of the restraint strap 17 exposed outside the fixing box 10. This tightens the restraint strap 17, thus limiting the child's wrist and preventing the child's wrist or palm from swinging during the infusion process. After the knob 19 is stopped, the first limiting rod 14 and the base plate 15 move towards the ratchet 12 under the drive of the first spring 16. When the bottom of the first limiting rod 14 is in contact with the ratchet 12, the first limiting rod 14 limits the ratchet 12. To prevent the rotating rod 11 from rotating in the opposite direction, when it is necessary to release the restraint strap 17 from the child's wrist and palm, pull the first limiting rod 14 away from the fixed box 10, so that the first limiting rod 14 and the ratchet 12 move away from each other, thereby releasing the restraint strap 17 from the child's wrist and palm. Pull the restraint strap 17, so that the restraint strap 17 rolled on the outside of the rotating rod 11 is extended, thereby increasing the length of the restraint strap 17 exposed on the outside of the fixed box 10, thereby releasing the restraint strap 17 from the child's wrist and palm or reducing the restraint of the restraint strap 17 on the child's wrist and palm, so that the device can be used for children with different wrist sizes, thus improving the applicability of the device.

[0030] In a preferred embodiment, please refer to Figure 3 A knob 19 is fixed at the end of the rotating rod 11 away from the fixed box 10, and the outer side of the knob 19 is provided with anti-slip texture.

[0031] In this embodiment, the anti-slip texture on the outer side of the knob 19 can effectively increase the friction between the fingers and the knob 19. When medical staff or users need to rotate the rotating rod 11 to adjust the tightness of the restraint strap 17, the anti-slip texture can prevent the fingers from slipping on the surface of the knob 19.

[0032] Secondly, please refer to it again. Figure 2 Each of the multiple restraint straps 17 has several ventilation holes 20 at its upper end.

[0033] In this embodiment, during the child's intravenous infusion, the skin is in contact with the restraint strap 17 for a long time. The vents 20 can increase air circulation and reduce the stuffiness and discomfort caused by wearing the restraint strap 17 for a long time.

[0034] Secondly, please refer to the following as well. Figure 2 and Figure 4The upper end of the fixed box 10 is provided with a third through hole 21 and a fourth through hole 22 from one side to the other. Inside the fixed box 10 and on both sides of the third through hole 21, a rotating shaft 23 is rotatably connected. Outside the rotating shaft 23 and inside the third through hole 21, a support plate 24 is fixed. Inside the fourth through hole 22, a rotating block 25 is provided, and the rotating shaft 23 and the rotating block 25 are fixedly connected.

[0035] It should be noted that the support plate 24 is adapted to fit the patient's palm. When placing the child's hand on the top of the fixing box 10, the child's palm needs to be aligned with the support plate 24.

[0036] In this embodiment, during intravenous infusion in children, if the child's wrist movement causes slight movement between the infusion needle and the child's wrist, resulting in the medication stopping or backflow of blood, rotating block 25 is used. This rotating block 25 drives the rotating shaft 23 and support plate 24 to rotate synchronously, adjusting the support angle of the support plate 24 on the child's palm. This, in turn, slightly adjusts the degree of wrist flexion, thus resolving the issue of medication stopping or backflow of blood caused by the child's wrist movement. Of course, the above embodiment is only one possible solution to the problem of medication stopping or backflow of blood. If the above problem cannot be resolved, medical personnel need to choose the correct solution based on the actual situation, such as re-inserting the needle.

[0037] To further understand and explain, Figures 4 to 5 For example, a fifth through hole 26 is provided on the side of the fixed box 10 away from the second through hole 18. A second limiting rod 27 is slidably connected inside the fifth through hole 26, and one side of the second limiting rod 27 passes through the fifth through hole 26. A baffle 28 is fixed on the outside of the second limiting rod 27 and inside the fifth through hole 26. A second spring 29 is provided on the side of the baffle 28 away from the rotating block 25, and the second spring 29 is located inside the fifth through hole 26. A plurality of grooves 30 are provided on the side of the rotating block 25 close to the second limiting rod 27, and the second limiting rod 27 and the grooves 30 are compatible.

[0038] In this embodiment, when the support plate 24 is adjusted to a suitable angle, the second spring 29 pushes the baffle 28 to move by elastic force. Since the baffle 28 and the second limiting rod 27 are fixedly connected, the second limiting rod 27 moves when the baffle 28 moves. Also, since multiple grooves 30 are provided on the outer side of the rotating block 25, and the second limiting rod 27 and the grooves 30 are matched, one side of the second limiting rod 27 can move to the groove 30 under the action of the second spring 29, thereby limiting the rotating block 25. The design of the second limiting rod 27 and the grooves 30 ensures that the rotating block 25 can only rotate within a preset angle range, avoiding safety hazards caused by excessive rotation.

[0039] The working principle of this utility model is as follows:

[0040] When adjusting the tightness of the restraint strap 17, turn the knob 19 clockwise. The knob 19 rotates the rotating rod 11, which in turn rotates the ratchet 12. The ratchet 12's rotation causes the restraint strap 17 to wrap around the rotating rod 11, tightening the restraint strap 17. Simultaneously, the clockwise rotation of the ratchet 12 pushes the first limiting rod 14 upwards. When the rotating rod 11 is no longer rotated, the ratchet 12 rotates counter-clockwise under the action of the restraint strap 17. At this point, the first limiting rod 14 engages the ratchet 12, preventing it from rotating counter-clockwise. When loosening the restraint strap 17... Move the first limiting rod 14 upwards, and the first limiting rod 14 will no longer engage with the ratchet 12. At this time, under the action of the restraint belt 17, the rotating rod 11 will rotate counterclockwise. The number of turns of the restraint belt 17 will decrease, and the effective length of the restraint belt 17 will increase, thereby loosening the restraint belt 17. When it is necessary to adjust the angle of the support plate 24, the rotating block 25 can be rotated by moving the second limiting rod 27. The rotation of the rotating block 25 can rotate the support plate 24 to adjust the angle. Loosen the second limiting rod 27 so that it engages with the groove 30 on one side of the rotating block 25. At this time, the rotating block 25 will no longer rotate, and the support plate 24 will no longer rotate.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
