Description

Detachable infusion tube connector

technical field

The utility model relates to the field of medical care, in particular to a detachable infusion tube connector.

Background technique

At present, the disposable infusion set needs to be connected with an indwelling needle when infusion to a patient, and then fixed with an applicator, and then reinforced with an adhesive tape. However, the fixation effect of the applicator is not ideal. Patients who sweat a lot, wash their hands frequently, and have a lot of hand activities are prone to problems such as curling, tape falling off, and poor fixation, resulting in needle removal, risk of hospital feeling and acupuncture. Risk of injury and interruption of infusion. Infusion set needles need to be replaced immediately.

In addition, patients often need to go out for examinations, and nurses are busy removing wound dressings and tapes, and replacing needles on disposable infusion sets. When the patient came back from the examination, he hurriedly re-sterilized the interface for the patient, exhausted the air, and wrapped the applicator and tape. It also wastes some medical resources.

If the patient needs to transfer to the toilet, eat, etc. during the infusion process, he must walk with the infusion bottle or infusion bag in the other hand, or need the help of another person, which is extremely inconvenient for the patient during the process.

The invention of an infusion tube that can be easily reconnected when a patient encounters an emergency and needs to stop the infusion for a short period of time after returning is a very practical product for patients, family members and nurses.
