Dripping speed regulator capable of being separated from infusion tube

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a dripping speed regulator capable of being separated from an infusion tube. The dripping speed regulator comprises a mounting seat detachably mounted on the infusion tube, a mounting groove is formed in the mounting seat, an extrusion bag is connected with one end of an extension tube, the other end of the extension tube is connected with a regulating device, and the regulating device is used for regulating air pressure in the extrusion bag and comprises a mounting head, an air inlet device and an air outlet device. In the infusion process, only the adjusting device needs to be placed near the hand of a patient without needle insertion, the speed can be adjusted or infusion operation can be stopped when the patient lies flat, the patient does not need to rotate in the speed adjusting process, and the infusion needle can be prevented from falling off due to rotation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a drip speed regulator which can be separated from a transfusion tube. Background technique [0002] The drip speed regulator is a common speed regulating device used in conjunction with the infusion tube, which is used to adjust the drip speed, and then adjust the infusion speed. A common drip speed regulator includes a mounting base and a rolling gear. The rolling gear can roll along the top length of the mounting base. The infusion tube passes through the mounting base and is located between the rolling gear and the inner bottom of the mounting base. The top is inclined relative to the bottom, and with the movement of the rolling gear, different pressures can be produced on the infusion tube, which changes the size of the liquid flow space inside the infusion tube, thereby realizing the adjustment of the flow rate. When the infusion is about to be complete...

Problems solved by technology

However, for urology patients, it often involves surgery on the urinary system. Urethral intubation, drainage tubes, etc. are commonly used medical equipment for urology patients. When these equipment are used, the patient's waist and lower limbs are inconvenient. In addition, one side of the patient's arm is receiving intravenous infusion, and three parts of the patient's limbs are inconvenient to move.

For the infusion of patients without accompanying persons, the other arm can only be used to adjust the drip speed regulator, which requires the arm to be transferred from one side of the body to the other side of the body, and the rotation of the arm can easily drive the rotation of the waist. Urology patients are not friendly, and when the arm adjusts the drip rate regulator, the strength is not well controlled, and the arm tends to reset, that is, it is easy to pull the infusion tube to the side where the infusion arm is not, and there is a risk of needle removal
