Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pediatric infusion nursing, especially relates to a palm fixing device for pediatric infusion. BACKGROUND

[0002] Pediatric patients need frequent intravenous injection, infusion and other operations due to the variety of diseases and rapid changes in illness, and children often feel afraid of infusion behavior, plus pain and discomfort, which easily leads them to show unstable behavior such as struggling and crying when receiving infusion, which not only increases the difficulty of medical operation, but also may affect the infusion effect and even cause needle displacement or falling.

[0003] Traditional pediatric infusion usually relies on the manual fixing of children's arms by parents or medical staff, and this method is low in efficiency and difficult to maintain stability for a long time, especially for lively and active children, and some simple hand support pads or splints on the market usually lack sufficient flexibility to adapt to children of different sizes, and have limitations in adjusting position and angle.

[0004] Based on the above background, the utility model aims to develop a palm fixing device for pediatric infusion which can effectively fix the hands of pediatric patients and has high comfort and good adjustability, so as to solve the above problems. UTILITY MODEL CONTENT

[0005] To solve the above technical problems, the utility model is realized by the following technical scheme:

[0006] The utility model is a palm fixing device for pediatric infusion, which comprises a fixing assembly, a support adjusting assembly adapted to be installed on the outside of the fixing assembly, and a palm lifting assembly matched with the support adjusting assembly.

[0007] The fixing assembly comprises a shell, an end seat fixed to the outer side of the shell, a screw rod threadedly connected to the center of the end seat, an adjusting knob fixed to the top of the screw rod, a transmission member movably connected to the bottom of the screw rod, a traction member movably connected to the side of the transmission member, and a clamping member connected to the bottom of the traction member.

[0008] The support adjusting assembly comprises a guide rod fixed to the upper end of the adjusting knob, a sleeve movably sleeved on the outside of the guide rod, a support arm fixed to the side of the sleeve, a spherical member fixed to the end of the support arm, and a spherical shell movably assembled on the outside of the spherical member.

[0009] The palm lifting assembly comprises a bottom plate fixed to the upper end of the spherical shell, a flexible pad fixed to the upper side of the bottom plate, and an elastic band provided at the end of the flexible pad.

[0010] The present invention is further configured such that the clamping member is movably connected to the inside of the housing via a shaft member, and a pair of clamping members are arranged opposite to each other, and the bottom protrusion of the clamping member is made of rubber.

[0011] The present invention is further configured such that a mounting groove is provided on the side of the guide rod, and the kit is fixed to the guide rod by fasteners.

[0012] The present invention is further configured such that the spherical shell is fixed to the spherical component via a fixing knob, and the spherical shell and the spherical component are in a transitional fit.

[0013] The present invention is further configured such that the surface of the flexible pad is provided with continuous protective texture, and the interior of the flexible pad is filled with a woven memory metal layer.

[0014] The present invention is further configured such that the elastic band has a built-in sensing layer, and the elastic band is pressed against the fingertips of the infusion hand.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting a fixing component, this utility model can securely fix the entire device to the bedside or other suitable positions, which not only improves the overall stability of the device, but also allows medical staff to easily adjust the clamping force as needed, ensuring that the device is firm and will not damage the support. By setting a support adjustment component, it provides height adjustability and multi-angle positioning function. Its flexibility allows the device to adapt to the body size and posture needs of different children, thereby improving the comfort during the treatment process and helping to reduce the restlessness of children caused by discomfort.

[0017] 2. This utility model enhances the comfort and stability of hand support by setting up a palm support component, especially the memory metal layer filled inside the flexible pad and the continuous protective texture on the surface. The memory metal layer can form an appropriate support shape according to the hand shape, while the protective texture increases friction and prevents the hand from slipping. In addition, the design of the elastic strap with built-in sensing layer can automatically adjust the tightness according to the pressure, which not only ensures effective fixation, but also avoids causing unnecessary pressure on the hand.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
