Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an anti-dislodgement buckling device for a saline bag infusion set. Background Technology
[0002] An infusion set is a common medical consumable. After sterilization, it is used to establish a channel between a saline bag and the patient's vein. It is commonly used for intravenous infusion and generally consists of a medication needle, tubing, drip chamber, flow regulator, puncture needle, and sealing cap. During use, the medication needle and puncture needle are inserted into the bag cap and the patient's vein, respectively, to complete the infusion process.
[0003] However, existing infusion sets still have shortcomings in use:
[0004] During intravenous infusion, patients often accidentally pull on the infusion tubing (especially agitated patients or children), or even pull the needle out of the bag stopper, causing contamination of the needle. In order to comply with the principle of aseptic operation, a new disposable infusion set must be replaced, which increases the economic burden on patients and the workload of medical staff.
[0005] In psychiatric settings, patients engaging in non-suicidal self-harm may detach the IV drip head during an episode to injure themselves or others. Therefore, designing an anti-detachment device to prevent the IV needle from dislodging from the saline bag during infusion has become a pressing issue in the medical device field. Utility Model Content
[0006] The purpose of this invention is to provide an anti-detachment buckling device for saline bag infusion sets, which can prevent the infusion needle from detaching from the saline bag opening during infusion, avoid the need to replace the infusion set due to contamination of the needle tip, and reduce the economic burden on patients and the workload of medical staff.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0008] A saline bag infusion set anti-dislodgement fastening device includes a male fastener and a female fastener. The male fastener has a male groove on its upper part, in which the opening of an existing saline bag is fastened and secured. The bag opening has a stopper and a ring groove. The female fastener has a female groove on its lower part, in which the medication needle of the existing infusion set is fastened and secured. The medication needle has a needle tip, needle wings, and a tube opening. The male fastener has a male connector on its lower part, and the female fastener has a female connector on its upper part. The male connector and the female connector are detachably connected, and the needle tip penetrates the stopper.
[0009] Compared with existing technologies, the anti-dislodgement buckle device for saline bag infusion sets, which adopts the above-mentioned technical solution, has the following beneficial effects:
[0010] This invention utilizes a saline bag infusion set anti-dislodgement fastening device. Medical staff fasten and secure the opening of the existing saline bag into the male groove, then fasten and secure the infusion set's medication needle into the female groove, with the needle tip inserted into the stopper. After the infusion is completed, the male and female fasteners are disconnected. This anti-dislodgement fastening device prevents the infusion set's medication needle from detaching from the saline bag opening during infusion, avoiding the need to replace the infusion set due to needle contamination, thus reducing the financial burden on patients and the workload of medical staff.
[0011] Preferably, the side wall of the male insert groove is provided with a retractable male locking block.
