Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an anti-indentation venous indwelling needle for children. Background Art
[0002] The intravenous indwelling needle is also called the intravenous cannula needle. The core components include the catheter / cannula that can be indwelled in the blood vessel, and the stainless steel puncture guide needle core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely in the blood vessel, the needle core is withdrawn, and only the catheter is indwelled in the blood vessel for infusion treatment.
[0003] When the current indwelling needle is in use, its overall structure is a cylindrical structure, and the sleeve is set at the center of one end of the base. After being inserted into the patient's vein, the indwelling needle is attached to one side of the patient's skin through the airplane wings located on both sides of the base and fixed by a film.
[0004] However, due to the overall structural design of the indwelling needle base, in order to achieve a stable fixation effect, it is often necessary to repeatedly stick and fix it with a film and a label. Since the overall cylindrical design is adopted, when the cannula is inserted into the vein and stuck tightly, the base close to the skin will pry the cannula inserted into the vein, causing discomfort to the child, and will form an indentation on the skin. When the sticking is loose, there are certain safety hazards due to the active habits of children. In view of this, we propose a child-proof indentation-proof intravenous indwelling needle. Utility Model Content
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a child-proof intravenous indwelling needle that prevents indentation marks, so as to solve the technical problems that the current indwelling needle adopts a cylindrical design as a whole, and when the sleeve is inserted into the vein and adhered tightly, the base close to the skin will pry the sleeve inserted into the vein, causing discomfort to the child, and will form an indentation on the skin; when the adhesion is loose, there are certain safety hazards due to the active habits of children.
[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a child-proof indentation-proof intravenous indwelling needle, including an indwelling infusion component and an adhesive positioning component arranged at the bottom of the indwelling infusion component for fixing the indwelling infusion component to the patient's skin surface;
[0007] The indwelling infusion assembly comprises a base, a sleeve is installed at the center of one end of the base, and a movable seat is installed at the other end of the base, and a needle core inserted in the sleeve is provided at one end of the movable seat facing the base;
[0008] The bottom ends of the base and the movable seat are both formed with an inclined surface A for reducing the angle between the sleeve and the user's skin, and an extension ear is constructed on one side of the movable seat. The bottoms of both sides of the base are fixedly installed with anti-indentation components for improving comfort, and the bonding and positioning components are bonded and fixed to the inclined surface A at the bottom of the base.
[0009] Preferably, the anti-indentation component comprises an airplane wing, the airplane wing is constructed at the bottom of one side of the base, and the bottom of the airplane wing remains parallel.
[0010] Preferably, a sponge layer is bonded and fixed to the bottom end of the aircraft wing, and an inclined surface B having the same slope as that of the inclined surface A is formed at the bottom end of the sponge layer.
[0011] Preferably, one side of the outer edge surface of the base is provided with an input port connected to the base, and an input pipe is fixedly installed in the input port.
[0012] Preferably, the bonding and positioning component includes a silicone pad, an adhesive layer is provided at the center of the top of the silicone pad, and the silicone pad is bonded and fixed to the surface of the inclined surface A through the adhesive layer.
[0013] Preferably, two through grooves are symmetrically provided on both sides of the top of the silicone pad, and the two sponge layers pass through the corresponding through grooves respectively.
[0014] Preferably, an adhesive layer is provided at the bottom of the silicone pad, and a release paper for protecting the adhesive layer is provided at the bottom of the silicone pad through the adhesive layer.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model completes the arrangement of the indwelling needle in the patient's vein through the indwelling infusion component, and adheres the indwelling infusion component to the patient's skin surface through the bonding and positioning component. Since the bottom of the base is formed with an inclined surface A, after the fixation to the user's skin is completed through the inclined surface A and the bonding and positioning component, the angle between the cannula arranged on the base and inserted into the patient's vein and the user's skin is greatly reduced, thereby avoiding the problem of children's discomfort caused by prying the cannula, and the fixing arrangement of the indwelling infusion component is completed at the bottom through the bonding and positioning component, which effectively reduces the problem of indentation formed by excessive contact between the indwelling infusion component and the child's skin, and avoids the problem of detachment due to children's hyperactivity, eliminating safety hazards.
[0017] 2. The utility model cooperates the two anti-indentation components arranged on the base through the bonding positioning component to further avoid the formation of indentations. The silicone pad is bonded to the user's skin surface by removing the release paper, and the sponge layer arranged at the bottom of the wing passes through the through groove on the silicone pad and abuts against the user's skin surface, thereby avoiding the problem of excessive squeezing of local skin, increasing the contact area, and further avoiding the formation of indentations.
