Liquid drop stopping bottle capable of preventing air inflow

Abstract

The invention relates to the technical field of medical instruments, and discloses an anti-air-inflow liquid-stopping dropping bottle which comprises a plastic needle, an extrusion catheter is fixedly connected to the lower portion of the plastic needle, a dropping bottle middle support is arranged in the middle of the inner side of the extrusion catheter, a filter screen is fixedly installed on one side of the dropping bottle middle support, and a floating valve is arranged at the bottom of the inner side of the catheter. According to the anti-air-inflow liquid-dropping-preventing bottle, during infusion, a plastic needle is inserted into a liquid medicine bottle, liquid medicine flows into the extrusion catheter through the plastic needle, when the liquid medicine flows into the upper portion of the interior of the extrusion catheter, the liquid medicine is filtered through a filter screen and then flows into the lower portion of the interior of the extrusion catheter, and when the liquid medicine flows into the lower portion of the interior of the extrusion catheter, the liquid medicine is filtered. After the liquid is accumulated, the floating valve floats and the liquid flows out due to the fact that the density of the floating valve is smaller than that of the liquid, and after the liquid flows out, the floating valve gradually descends along with the descending of the liquid level of the liquid medicine, so that the gas can be blocked in time and prevented from entering the human body.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an air-intake-proof anti-drop bottle. Background technique [0002] The infusion set is a common medical consumable. After aseptic treatment, a channel between the vein and the liquid medicine is established for intravenous infusion. Generally, it is composed of eight parts such as venous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, cork puncturer, air filter, etc. Some infusion sets also have injection parts , dosing port, etc. [0003] When the infusion is about to end, there is no automatic liquid stop function. When the caregiver or patient does not notice that the infusion is almost over, without notifying the nurse or doctor, when the liquid is dripped through the infusion set, the infusion needle will stop. When it is not pulled out from the patient's body, it will cause the patient's blood to fl...

AI Technical Summary

Problems solved by technology

[0003] When the infusion is about to end, there is no automatic liquid stop function. When the caregiver or patient does not notice that the infusion is almost over, without notifying the nurse or doctor, when the liquid is dripped through the infusion set, the infusion needle will stop. When it is not pulled out from the patient's body, it will cause the patient's blood to flow back, which is easy to cause danger to the patient. In addition, the existing infusion set is directly inserted into the top of the infusion bottle, but the infusion set is under the touch of external force. As a result, it is easy to cause the plastic needle to fall violently from the top of the infusion bottle, thereby affecting the patient's infusion, and when the patient is infused in cold weather, because the existing infusion device does not have an automatic heating device, when the cold liquid medicine is injected into the human body, it will cause the human body to lose weight. A situation that causes discomfort occurs
