Abstract

The invention discloses an auxiliary tool for adjusting the length of an extension pipe in the field of clinical medical technology. One end extends through the bottom of the pressing roller and the top of the auxiliary roller to the right end of the installation frame, and the right end of the extension tube extends to the right outer wall of the installation frame and is connected with an indwelling needle, and the left end of the connection between the extension tube and the indwelling needle is provided with a backflow prevention component , the left end of the connection between the extension tube and the anti-reflux component is slidably sleeved with a movable clip. When the tube needs to be sealed after the liquid is transported, the screw rod is rotated to make the connecting plate drive the upper pressure roller to squeeze the extension tube. When the upper pressure roller continues to squeeze When the extension tube is pressed, the extension tube can be sealed to prevent the tube-sealing liquid or the drug remaining in the indwelling needle from entering the extension tube, which may cause the weakening of the tube-sealing effect or the deterioration of the drug.

Description

An auxiliary tool for easy adjustment of the length of the extension pipe

technical field

The invention relates to the technical field of clinical medical treatment, in particular to an auxiliary tooling which is convenient for adjusting the length of an extension tube.

Background technique

The extension tube is a medical device widely used in clinic, especially the pump extension tube. When a patient needs to use the drug at a lower speed, a pump-type extension tube is often selected, one end of which is connected to a syringe, and the other end is connected to an indwelling needle. However, in the actual use process, it is found that the pump-type extension tube has many shortcomings: due to the fixed length, the patient cannot perform large-scale activities, and even the most basic bed turning is limited, which brings inconvenience to the patient; When the infusion at one end is completed and the drug at the other end needs to be continuously injected at a small speed, in order to prevent the indwelling needle from being blocked, the nurse needs to seal the tube from the end of the infusion end, because there is no device installed on the pump extension tube to prevent liquid reflux , therefore, the extension tube can only be temporarily reversed by the nurse's manual reflexion, and the tube can be released manually after the tube is sealed. and the residual drug in the indwelling needle will flow back into the extension tube, which will cause ineffective tube sealing and mixing of different drugs; because the pump-type extension tube is used, the drug bolus injection speed is slow, the pressure is low, and the blood is easy to return to the extension tube. , causing blood coagulation and blocking the pipeline; during the infusion process, the patient urinates a lot and often needs to go to the toilet, and there is no switch on the extension tube like the infusion set, so the nurse is urgently needed to help suspend the infusion. service, resulting in tension between nurses and patients, and also increased the workload of nurses. To this end, we propose an auxiliary tool that is convenient for both patients and nursing staff to adjust the length of the extension tube.
