A Toomey syringe is a large-capacity syringe, usually 60 mL, distinguished by its wide, open catheter tip instead of the narrow Luer-lock or Luer-slip tip found on standard syringes. That broad opening is the whole point: it lets you push and pull thicker fluids, flush catheters without excessive pressure buildup, and move larger volumes quickly. You will find Toomey syringes in hospital supply carts, home care kits, and veterinary clinics, and once you understand what makes this syringe different, you start noticing how many bedside procedures depend on it.
What Makes a Toomey Syringe Different from a Regular Syringe
The defining feature is the tip. Most syringes taper to a small cone that accepts a needle or locks into one via a threaded collar. A Toomey syringe skips that entirely. Its tip is a smooth, tapered nozzle wide enough to slide directly into the funnel end of a Foley catheter, a nasogastric tube, or a feeding tube. There is no needle involved in any typical Toomey application.
The barrel is also larger than what most people picture when they hear “syringe.” At 60 mL, it holds roughly four tablespoons of fluid per draw. The plunger has a broad, flat thumb rest so you can push or pull with one hand while the other holds tubing in place. Some versions have a slightly curved tip for easier catheter connections, and the barrel markings are printed in bold increments because precision down to the tenth of a milliliter is not the point here. The point is moving a meaningful volume of fluid in or out, efficiently and without clogging.
The materials are unremarkable: medical-grade polypropylene or polycarbonate for the barrel, a rubber or silicone gasket on the plunger to maintain the seal. Toomey syringes are almost always disposable, sold sterile and individually wrapped. You will occasionally see reusable glass versions in older surgical kits or veterinary settings, but the disposable plastic type dominates modern use.
Bladder Irrigation and Clot Removal
The most well-known clinical use of the Toomey syringe is flushing the urinary bladder through a Foley or three-way catheter. After prostate surgery, bladder surgery, or any procedure that leaves blood in the bladder, clots can form and block the catheter. A plugged catheter means the patient cannot drain urine, which is painful and potentially dangerous. The standard fix is to connect a Toomey syringe to the catheter port, draw back to pull clots out, then push saline in to break up whatever remains.
The Toomey syringe is preferred for this job because the suction pressure it generates is considerably higher than what you get with an Ellick evacuator, a bulb-style device sometimes used for the same purpose. That extra suction matters when clots are old and sticky. An Ellick evacuator can struggle with tenacious clots, while the Toomey’s plunger lets the clinician control exactly how much negative pressure to apply on each pull. 1PubMed Central. Clot Retention: Our Experiences with a Simple New Technique of Evacuation with a Thoracic Catheter The technique is straightforward: fill the syringe with sterile saline, push it gently into the bladder through the catheter, then pull back. Whatever comes out goes into a basin for inspection. Repeat until the return fluid runs clear or until the catheter drains freely on its own.
When mechanical suction is applied carefully during clot evacuation, outcomes are generally good. One study examining suction-based clot removal from the bladder found that, aside from minor surface bleeding spots on the bladder lining, no complications were encountered. 2Urology. Mechanical suction: an effective and safe method to remove large and tenacious clots from the urinary bladder That said, overly aggressive irrigation or aspiration with any syringe, including a Toomey, can occasionally cause bladder perforation, so the technique requires a measured hand. 1PubMed Central.

Feeding Tubes and Enteral Nutrition
If you or a family member have dealt with a nasogastric (NG) tube or a gastrostomy tube (G-tube, PEG tube), you have probably already met a Toomey syringe. The catheter tip fits snugly into the external port of most feeding tubes, making it the go-to tool for several routine tasks: checking residual stomach contents before a feeding, flushing the tube with water to prevent clogging, and administering liquid medications or formula when a feeding pump is not in use.
Checking residual volume is a common nursing assessment. The nurse connects the Toomey syringe to the feeding tube, gently pulls back on the plunger, and measures how much stomach content returns. A high residual can signal delayed gastric emptying and may prompt the care team to hold or slow the feeding. Because the Toomey syringe has a wide bore, it handles the sometimes thick, partially digested formula without jamming the way a narrow syringe would.
Flushing is equally important. Feeding tubes clog more often than most people expect, especially when crushed medications are pushed through them. Running 30 to 60 mL of warm water through the tube after every feeding or medication pass is standard practice, and a Toomey syringe delivers that volume in a single smooth push. Some home-care patients keep several on hand and reuse them for a short period between replacements, though hospital protocol is single-use.
Wound Irrigation
Flushing a wound with pressurized saline to remove debris and bacteria is one of the simplest and most effective ways to prevent infection. The general principle is well supported: in a study of complicated appendectomy cases, patients whose surgical wounds received syringe-pressure irrigation with saline had dramatically lower infection rates than those who did not. 3PubMed.

Wound irrigation setups vary. Some use a standard syringe with a needle or catheter tip attached to generate a focused stream, while others use a Toomey syringe when a broader, high-volume flush is desired. The Toomey is especially useful for larger wounds or open cavities where you need to move a lot of saline quickly but do not want the pinpoint pressure of a needle-tipped irrigator. Emergency departments, operating rooms, and wound-care clinics all stock them for this reason. The wide tip also means less risk of accidentally puncturing tissue compared to setups that involve a needle.
Other Clinical and Home-Care Uses
Beyond the big three of bladder irrigation, tube feeding, and wound care, Toomey syringes show up in a surprising number of settings:
- Ear irrigation: Some practitioners use a Toomey syringe to flush impacted earwax with warm water, though purpose-built ear irrigation syringes with splash guards are more common in primary care offices now.
- Chest tube management: In thoracic procedures, a Toomey syringe can be used to aspirate fluid or air through a chest drain, particularly when testing for leaks or sampling pleural fluid.
- Veterinary medicine: Large-animal vets reach for Toomey syringes to flush wounds, irrigate abscesses, and administer oral medications to animals that cannot swallow pills.
- Colostomy and ileostomy care: Patients with ostomies sometimes use a Toomey syringe to irrigate the stoma, helping regulate bowel function and reduce the need for a collection pouch throughout the day.
The common thread is always the same: you need to move a moderate to large volume of fluid through a tube or into a body cavity, without a needle, and with enough control to vary the pressure by hand.
How to Use One Correctly
If you have been sent home with a Toomey syringe for tube-feeding care or wound irrigation, a few practical points help avoid common mistakes.
First, connect the tip firmly but do not force it. The catheter tip is designed to create a snug friction fit inside the tube’s port. If you jam it in too hard, you risk cracking the tube connector or making the syringe difficult to detach. A gentle twist-and-push is enough.
Second, push the plunger slowly. The temptation is to give a quick, firm push to get the flush over with, but that spike in pressure can cause discomfort (in bladder irrigation) or dislodge a feeding tube. Slow, steady pressure gives the fluid time to flow through the tube and spread evenly.
Third, when aspirating (pulling back), do not yank the plunger. Gentle, steady traction prevents tissue from being sucked against the catheter tip, which can cause pain or minor injury to the bladder or stomach lining. If you meet strong resistance while pulling back, stop and reposition the tubing before trying again.
Fourth, flush with plain water after every use if you are reusing the syringe at home. Dried formula or medication residue inside the barrel makes the plunger stick, and a sticky plunger means uneven pressure on the next use. Most home-care guidelines suggest replacing the syringe every 24 to 48 hours even with cleaning, since the rubber gasket loses its seal with repeated use.
Common Mix-Ups and Misconceptions
People sometimes confuse a Toomey syringe with a catheter-tip syringe and assume the two terms are interchangeable. They are closely related but not identical in every product line. “Catheter-tip syringe” is a broader category describing any syringe whose tip is designed to connect directly to a catheter or tube. A Toomey syringe is a specific type within that category, traditionally associated with a 60 mL barrel and a particular tip profile. In practice, many manufacturers label their 60 mL catheter-tip syringes as “Toomey” regardless of minor design differences, so the terms have blurred. If a medical professional asks you to pick up a Toomey syringe, a 60 mL catheter-tip syringe from any reputable brand will almost certainly be what they mean.
Another misconception is that a bigger syringe always delivers more pressure. It is actually the opposite. Pressure equals force divided by the area of the plunger. A 60 mL Toomey syringe has a wider barrel than a 10 mL syringe, so the same push on the plunger produces lower pressure per unit area. That is by design: the Toomey delivers volume, not concentrated force. When a clinician needs high-pressure irrigation for a deep wound, they often switch to a smaller syringe with a narrow tip or an attached catheter to focus the stream. The Toomey’s strength is throughput and gentle pressure over a wide area.
Finally, some people assume that because the Toomey syringe is simple and sold over the counter, it is entirely risk-free. It is safe when used as intended, but irrigating a body cavity always carries a small risk of introducing bacteria if sterile technique is not followed, or of tissue injury if too much pressure is applied. Bladder perforation, though rare, is a recognized complication of aggressive manual irrigation. 1PubMed Central. Clot Retention: Our Experiences with a Simple New Technique of Evacuation with a Thoracic Catheter Home-care patients should follow the specific instructions their care team provides rather than improvising.
Why the Syringe Is Named “Toomey”
The name comes from its original designer, though the precise origin is poorly documented compared to many other eponymous medical instruments. What is clear is that the design has been in continuous clinical use for decades, referenced in urological literature as far back as the late 1970s and early 1980s. Over the years, the basic concept has barely changed: a large, open-tipped syringe built for catheter work. Modifications have appeared for specialized tasks, but the core geometry of a wide barrel with a smooth catheter tip has proved so practical that it has resisted redesign. In an era when many disposable medical devices are re-engineered every few years, the Toomey syringe remains essentially the same tool it was a generation ago.
Purchasing and Availability
Toomey syringes are inexpensive and widely available. You can buy them individually or in bulk from medical supply retailers, pharmacies, and online stores. Prices typically range from one to three dollars per syringe, though bulk packs bring the per-unit cost down further. You do not need a prescription to purchase one.
When shopping, look for syringes that are individually sealed in sterile packaging if you plan to use them for any procedure that contacts an open wound, a catheter inside the body, or a feeding tube. Non-sterile versions exist and are fine for tasks like flushing external equipment or mixing solutions, but they are not appropriate for clinical or home-care irrigation. Most packaging will clearly state “sterile” and carry a lot number and expiration date. Expired syringes are not dangerous in themselves, but the sterility guarantee no longer holds, so treat them as non-sterile.
Brand differences are minimal. The barrel graduation markings, plunger feel, and tip taper vary slightly between manufacturers, but the functional performance is essentially identical. If your home-care instructions specify a particular brand, follow them; otherwise, any major medical supply brand’s 60 mL catheter-tip or Toomey syringe will work. Some patients develop a preference for a specific brand because they like the plunger resistance or the feel of the tip connection, which is perfectly reasonable when you are using the device multiple times a day for tube feeding care.
