A kind of infusion set for pediatric nursing

Abstract

The invention discloses an infusion set for pediatric nursing, which comprises a dripping pot, a puncture head, an infusion needle and a flow regulator. The outer wall of the lower infusion tube is also movably provided with a clamp assembly which is convenient for coiling the lower infusion tube with each other; the clamp assembly includes A lower splint, an upper splint rotatably arranged on the lower splint through a rotating shaft, and a torsion spring arranged between the upper splint and the lower splint; the drip pot includes a lower pot body, an upper pot body and a backflow prevention mechanism; the backflow prevention mechanism Including baffle, guide plate, sealing assembly and reset structure. The present invention utilizes the force of the reset structure on the sealing assembly, so that when there is no infusion or the liquid height on the baffle is less than the set height, the sealing assembly is in close contact with the baffle under the action of the reset structure; at the same time, when the blood pressure increases , During the backflow process of the blood down the infusion tube, the liquid at the lower end of the sealing component is pushed, so that the contact between the sealing component and the lower side of the baffle is more closely, so as to prevent blood backflow more effectively.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an infusion set for pediatric nursing. Background technique [0002] The infusion set is a common medical consumable, which is aseptically processed to establish a channel between the vein and the liquid medicine for intravenous infusion. Generally, it includes intravenous needles or injection needles, needle guards, infusion tubes, flow rate regulators, drip pots, puncture heads and exhaust pipes. [0003] At present, the infusion recipients in the pediatrics are mainly children. Once blood flows back into the infusion tube, the children will be nervous or panic when they see the blood. A blood-return prevention mechanism needs to be set up in the pediatric infusion set. The infusion set often adopts a floating ball type blood-return prevention mechanism in the dripping pot of the infusion set; the infusion set of the prior art also has the following defects and shortcomings: the...

AI Technical Summary

Problems solved by technology

[0003] At present, the infusion users in pediatrics are mainly children. Once the blood backflows into the infusion tube, the child will be nervous or panic when seeing the blood. In the pediatric infusion set, it is necessary to set up an anti-blood return mechanism. In the patent literature of the prior art The infusion device often adopts the floating ball type anti-blood return mechanism in the drip pot of the infusion device; the infusion device of the prior art also has the following defects and deficiencies: the infusion tube is too long, and it is easy to be entangled during use; when the blood pressure of the human body increases , in the process of blood returning to the infusion tube, it will push the liquid at the lower end of the sealing assembly, thereby pushing the blocking rod to move, which will cause the anti-blood return effect to fail
