A drainage bag with tight interface connection and strong practicability

Abstract

The invention relates to the technical field of medical devices, and discloses a drainage bag with tight interface connection and strong practicability, including a drainage bag and a casing, the outside of the drainage bag is movably connected with a catheter, and the outside of the catheter is fixedly connected with a card holder. The internal movable connection of the deck is connected with non-Newtonian fluid, the internal movable connection of the deck is connected with connecting rod 1, the external movable connection of connecting rod 1 is connected with connecting rod 2, the internal fixed connection of the deck is connected with a spring, and the external movable connection of the spring is connected with a card Block; through the interaction between the catheter, the card seat, the non-Newtonian fluid, the first connecting rod, the second connecting rod, the spring, the block, the block, the buckle, the card head and the card groove, the liquid inlet pipe and the drainage can be made The connection between the catheters connected to the outside of the bag can be reinforced in a variety of ways. Through the use of different reinforcement methods, the catheter can be shaken by the patient on the bed or other places without causing the catheter to slip off, which is more suitable. patient use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage bag with tightly connected interfaces and strong practicability. Background technique [0002] Drainage bag generally refers to the bleeding and effusion inside the body or in the deep part of the operation after the operation, which need to be drawn out with a tube. The end of the drainage tube is connected to a transparent plastic bag specially designed to hold the drained liquid. The commonly used drainage bag is a disposable drainage bag, which is made of medical polymer material and packaged in a low-pressure PE bag. The drainage bag is mainly used to collect urine from patients with urinary incontinence, surgically comatose patients and people with limited mobility or cooperate with other devices for the collection of wound drainage fluid. [0003] When a drainage bag is needed in the treatment of a patient, it is generally connected to the drainage bag ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a drainage bag with tight interface and strong practicability, which has the advantages of tight interface and strong practicability, and solves the problem of using the drainage bag in the treatment of patients. The end of the catheter that passes through the patient's body is connected to the drainage bag through a temporary transfer, so there is a possibility that the catheter will slip off, and the possibility is relatively large, so it is easy for the external drainage bag to slip from the catheter due to the patient's body position on the bed. The slippage of the joint will cause the drainage fluid to overflow and cause pollution or reflux of the drainage fluid, which will cause or aggravate the patient's condition, which will affect the normal recovery of the patient and increase the pain of the patient; and the connection between the catheter and the drainage bag is incorrect. If it is tight, it will affect the airtightness of its connection, which will cause changes in the negative pressure inside the patient's wound, which will more easily cause the problem of infection in the patient
