Patient pyjama or nightgown based on a system of slots

Developed by: Instituto de Investigación Sanitaria Hospital La Paz


Description and essential characteristics

The patient pyjama or nightgown includes a system of openings and buttonholes strategically distributed for the location of drains and catheters and to facilitate medical care. Broadly speaking, this is a system adapted to the design of a standard pyjama or nightgown—adult or child size—available on the market.

The system contains two types of slots: “partial” and “total.” The partial slots are variable in length, have vertical or horizontal orientation (depending on the area where they are located), and are bilaterally distributed in the most frequent entry and exit points of catheters: bend of the elbow, shoulder, body side lateral, hip lateral and knee lateral.

The buttonholes on the garment incorporate a reinforcement made of the same material as that surrounding the slot, which prevents wear due to prolonged use. Buttonhole finishing can include a closure system, which must be hygienic and resistant to daily use, such as fasteners, buttons or Velcro.

The total slots are bilaterally distributed along the sleeve seam, along the body side seam and along the trouser seam. These slots get their name because they occupy the entire portion of the garment where they are located, at the place where the seam is usually made. By incorporating a closure system—Velcro, fasteners or buttons—complete exposure of the anatomical area is possible.

The number and distribution of the openings that each garment finally incorporates will vary depending on the type of procedure undergone by the patient—medical or surgical procedure. 

Competitive advantages

The design of this garment for patients can mean an improvement in healthcare quality and in the image the patient has regarding clinical care.  

First, its design is adapted to the needs of the hospital environment, thus facilitating the daily care that wounds, catheters and probes require by providing easy access to the site of medical treatment. Its design is versatile, being useful for a number of medical specialties. 

Second, from the patient's point of view, this pyjama avoids inconveniences resulting from the placement of medical devices, such as discomfort (e.g., sleeve bends, unfastened openings) and the involuntary dislodging of devices such as sera infusion systems, drains and catheters.

Finally, the pyjama means an improvement in the cost-benefit ratio, as it avoids having to tear the patient’s clothes to facilitate daily clinical care, and the incorporation of these slots does not involve a significant increase in the garment’s unit price.
