Description

The MIC-KEY Low Profile Jejunal Tube is a specialized medical device designed to provide enteral nutrition directly into the jejunum for both pediatric and adult patients. Manufactured by Ballard Medical Products and distributed by Kimberly-Clark, this tube is particularly beneficial for individuals who cannot absorb adequate nutrition through the stomach due to various medical conditions such as severe gastroesophageal reflux, gastric outlet obstruction, or post-surgical needs.

Design and Functionality

This tube features a low-profile, button-style design that sits discreetly against the skin, enhancing comfort and reducing visibility. It includes multiple ports: a jejunal port for feeding, a gastric port for decompression, and a balloon port for inflating the internal retention balloon. The retention balloon, made of medical-grade silicone, secures the tube in place, while the external bolster ensures stability and allows air circulation.

Compatibility and Security

The MIC-KEY tube is compatible with MIC-KEY Extension Sets, available with ENFit or catheter tips, depending on the model. Its connector mechanism, featuring a lock-and-key or SECUR-LOK system, provides secure attachment, minimizing the risk of disconnection. An anti-reflux valve is integrated to prevent leakage of stomach contents, enhancing safety during use.

Imaging and Insertion

A radiopaque stripe allows for easy visualization under imaging, and the weighted jejunal portion helps maintain proper positioning. The tube's distal tip is trimmable and tapered, facilitating non-traumatic insertion and customization to the patient's needs. Clearly marked ports aid in the easy identification of gastric and jejunal access points.

Sizes and Specifications

Available in various French sizes ranging from 12 Fr to 22 Fr, the tube offers different stoma and jejunal lengths to accommodate individual requirements. Balloon fill volumes vary, with smaller volumes for pediatric use and larger for adults. The tube is supplied sterile, intended for single-patient use, and requires a prescription.

Maintenance and Care

Proper care involves daily cleaning of the tube and stoma site, regular flushing with water, and weekly checks of the balloon volume. The use of MIC-KEY extension sets is recommended, with replacements every two weeks. Patients are advised not to rotate the tube unless instructed and to follow specific guidelines for medication administration and feeding.

Placement and Replacement

Placement is typically performed under fluoroscopic or endoscopic guidance, and replacement should be managed by a healthcare professional unless otherwise trained. Some models may require endoscopic procedures for replacement, emphasizing the need for professional oversight.

Packaging

The device is packaged individually, with example dimensions of approximately 32 cm in length, 23 cm in width, and 6 cm in height, weighing around 0.55 kg. It is non-returnable and should be used only as directed by a healthcare provider, ensuring adherence to recommended practices for optimal outcomes.
