A device for fixing and preventing dislodgement of pediatric indwelling intravenous catheters

Abstract

This utility model discloses a device for fixing and preventing dislodgement of intravenous catheters in children, specifically involving an infusion tray. The tray includes a tray with a centrally located shallow groove filled with gas. The gas, when inflated, consists of an arc-shaped dome and multiple equidistant connecting posts positioned on the dome. Half of the connecting posts are connected to the inner wall of one side of the shallow groove, while the other half are attached to the side of the tray via Velcro. This utility model has a simple structure and is easy to operate. It can cover the area where the indwelling needle is fixed in the arm, preventing it from being scraped and dislodged.

Description

Technical Field

[0001] This utility model relates to an infusion support, specifically to a device for fixing and preventing dislodgement of intravenous catheters in children. Background Technology

[0002] The use of indwelling intravenous catheters can reduce the pain and fear of injections caused by repeated venipunctures in children, alleviate the anxiety of parents, facilitate clinical medication administration, and facilitate the emergency medication administration of critically ill patients. It can also reduce the workload of nurses and reduce the pain of children. Therefore, indwelling intravenous catheters are widely used in clinical practice.

[0003] The core components of an indwelling needle include a flexible catheter / cannulas that can be left in a blood vessel, and a stainless steel puncture guide needle core. When in use, the catheter and needle core are inserted into the blood vessel together. After the catheter is fully inserted into the blood vessel, the needle core is withdrawn, leaving only the flexible catheter in the blood vessel for infusion therapy. The connector needs to be fixed to the patient's palm or the infusion site.

[0004] Currently, the support plates used for intravenous catheterization in children are all homemade straight boards (cardboard, wooden boards, etc.). They are uniform in color and made of hard material. The connector of the indwelling needle is fixed to the back of the hand. Although this can prevent the needle from moving on its own, it can be moved or pulled out due to pressure during sleep or accidental scratching by the child. This makes the indwelling needle unusable and inconvenient to use, and is rejected by nursing staff, children and parents.

[0005] A child indwelling needle fixing device disclosed in Chinese Utility Model Patent Application Publication CN209270501U, although this child indwelling needle fixing device, due to the addition of a cover plate, sleeve, moving rod and connecting parts, is designed to protect the indwelling needle, prevent the indwelling needle from colliding with external objects during the child's movement, and prevent the child from pulling too much on the infusion tube, thus improving the stability of the indwelling needle in the child's hand, solves the drawbacks of the prior art where children easily pull on the infusion tube during infusion, which can easily lead to the indwelling needle falling off and poor infusion stability. However, this child indwelling needle fixing device has the disadvantages of not being securely fixed, using many hard parts that can easily cause injury to children, and the indwelling needle being easy to fall off, resulting in poor infusion stability. Utility Model Content

[0006] The purpose of this invention is to provide a device for fixing and preventing the dislodgement of intravenous catheters in children, in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for fixing and preventing dislodgement of an indwelling intravenous catheter in children includes a support plate with a storage compartment on one side, and the storage compartment is filled with gas.

[0009] The inflatable gas in the inflated state is structurally divided into an arc-shaped dome and multiple equidistant connecting columns disposed on the arc-shaped dome.

[0010] One-half of the connecting posts are connected to one side of the tray, while the other half of the connecting posts are connected to the side of the tray via Velcro.

[0011] Preferably, side wing plates are inserted into both ends of the tray, and silicone pads are provided on the side wing plates and the tray.

[0012] Preferably, the side wing plate is provided with adjustable restraint straps.

[0013] Preferably, the top of the arc-shaped dome has a window, and a cover is embedded in the window.

[0014] Preferably, the cover is connected to the window via a flexible band.

[0015] Preferably, multiple equidistant connecting posts along the length of the pallet avoid forming an arm penetration area.

[0016] In the above technical solution, the present invention provides a pediatric intravenous indwelling needle fixation and anti-dislodgement protection device, which has the following beneficial effects: the inflated gas in the inflated state covers the support plate like a cover, thereby covering the arm placed on the support plate and covering the indwelling needle. The entire inflated state is in the form of an arc-shaped dome and multiple equidistant connecting columns set on the arc-shaped dome. Therefore, the gap between each connecting column ensures the internal airflow after the cover is covered, and also makes it convenient for the nurse to observe the status of the indwelling needle through the gap. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, a device for fixing and preventing dislodgement of a pediatric indwelling intravenous catheter includes a support plate 1, with a storage compartment on one side, and an inflatable gas 3 inside the storage compartment;

[0025] In use, the side wing plates 2, which are inserted at both ends of the support plate 1, are stretched according to the length of the patient's arm, thereby increasing the overall support surface. A rubber damping ring is provided at the joint between the two, and the plate is fixed after adjustment by damping force.

[0026] When using it, first pull out the gas 3, and then use the adjustable restraint straps 4 on the side wing plate 2 to bind and fix the arm placed on the support plate 1, and then perform the indwelling needle puncture.

[0027] Furthermore, the gas filling 3 is structurally divided into an arc-shaped dome 31 and multiple equidistant connecting columns 32 disposed on the arc-shaped dome 31. In this embodiment, half of the connecting columns 32 are connected to one side of the support plate 1, while the other half of the connecting columns 32 are connected to the side of the support plate 1 via Velcro.

[0028] Inflation is achieved through the air inlet on the outer side of the curved dome 31, so that the inflatable gas 3 is fully inflated, as shown below. Figure 2 As shown, at this point, the connecting post 32 with the hook and loop fastener is then combined with the hook and loop fastener side of the tray 1, i.e. Figure 3 As shown, this allows the gas 3 to cover the indwelling needle after puncture.

[0029] Furthermore, in combination Figure 2 and Figure 1 As shown, the top of the arc-shaped dome 31 has a window 311, and a cover 5 is embedded in the window 311. The cover 5 is connected to the window 311 by a flexible strip, such as a cloth strip or a plastic strip. The puncture needle can then be viewed by removing the cover 5 from the window 311.

[0030] Furthermore, the surface of the inflatable gas 3 in the embodiment can be decorated with cartoon paintings, or the entire inflatable gas 3 can be in the shape of a cartoon.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
